(find_newline_no_quit): Likewise for start position. * lisp.h (find_newline, find_newline_no_quit): Adjust prototype. * bidi.c (bidi_find_paragraph_start): Pass byte position to find_newline_no_quit, thus eliminating CHAR_TO_BYTE. * editfns.c (Fconstrain_to_field): Break long line. Adjust call to find_newline. * indent.c (vmotion): Adjust calls to find_newline_no_quit. Use DEC_BOTH to start next search from the previous buffer position, where appropriate. * xdisp.c (back_to_previous_line_start, forward_to_next_line_start) (get_visually_first_element, move_it_vertically_backward): Likewise.

Add eassert. 2013-03-06 Paul Eggert Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881). * sysdep.c (list_system_processes) [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]: Make it a stub in this case; otherwise the build might fail, and this code hasn't been tested on such hosts anyway. Problem reported by Nelson H. F. Beebe in and analyzed by Jérémie Courrèges-Anglas in . 2013-03-06 Dmitry Antipov * lisp.h (find_next_newline_no_quit): Rename to find_next_newline. * xdisp.c (back_to_previous_line_start, forward_to_next_line_start) (get_visually_first_element, move_it_vertically_backward): Adjust users. * bidi.c (bidi_find_paragraph_start): Likewise. * indent.c (vmotion): Likewise. 2013-03-05 Paul Eggert FILE's lock is now always .#FILE and may be a regular file (Bug#13807). * filelock.c: Include . (MAX_LFINFO): New top-level constant. (lock_info_type): Remove members pid, boot_time. Add members at, dot, colon. Change user member to be the entire buffer, not a pointer. This allows us to handle the case where a foreign pid or boot time exceeds the local range. All uses changed. (LINKS_MIGHT_NOT_WORK): New constant. (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing. (defined_WINDOWSNT): Remove. (MAKE_LOCK_NAME, file_in_lock_file_name): Always use .#FILE (not .#-FILE) for the file lock, even if it is a regular file. (rename_lock_file): New function. (create_lock_file): Use it. (create_lock_file, read_lock_data): Prefer a symbolic link for the lock file, falling back on a regular file if symlinks don't work. Do not try to create symlinks on MS-Windows, due to security hassles. Stick with POSIXish functions (open, read, write, close, fchmod, readlink, symlink, link, rename, unlink, mkstemp) when creating locks, as a GNUish host may be using a Windowsish file system, and cannot use MS-Windows-only system calls. Fall back on mktemp if mkstemp doesn't work. Don't fail merely because of a symlink-contents length limit in the current file system; fall back on regular files. Increase the symlink contents length limit to 8 KiB, this should be big enough for any real use and doesn't crunch the stack. (create_lock_file, lock_file_1, read_lock_data): Simplify allocation of lock file buffers now that they fit in 8 KiB. (lock_file_1): Return error number, not bool. All callers changed. (ELOOP): New macro, if not already defined. (read_lock_data): Return size of lock file contents, not Lisp object. All callers changed. Handle a race condition if some other process replaces a regular-file lock with a symlink lock or vice versa, while we're trying to read the lock. (current_lock_owner): Parse contents more carefully, to help avoid confusing a regular-file lock with some other application's use of the file. Check for lock file contents being too long, or not parsing correctly. (current_lock_owner, lock_file): Allow foreign pid and boot times that exceed the local range. (current_lock_owner, lock_if_free, lock_file): Simplify allocation of lock file contents. * w32.c (sys_rename_replace): New function, containing most of the contents of the old sys_rename. (sys_rename): Use it. (fchmod): New dummy function. * w32.h (sys_rename_replace, fchmod): New decls. 2013-03-05 Eli Zaretskii * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or bidi_count_bytes, as the callers now arrange for bidi_it->charpos to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov . 2013-03-05 Dmitry Antipov * composite.c (get_composition_id, fill_gstring_header): Use make_uninit_vector where appropriate. * font.c (Ffont_get_glyphs, build_style_table): Likewise. * xselect.c (clean_local_selection_data): Likewise. 2013-03-04 Paul Eggert Fix misuse of ImageMagick that caused core dump (Bug#13846). * image.c (imagemagick_load_image): Calculate height and width after flattening the image, not before. 2013-03-04 Dmitry Antipov * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW. * ftfont.c (ftfont_shape_by_flt): Likewise. * w32uniscribe.c (uniscribe_shape): Likewise. 2013-03-02 Paul Eggert The lock for FILE is now .#FILE or .#-FILE (Bug#13807). The old approach, which fell back on DIR/.#FILE.0 through DIR/.#FILE.9, had race conditions that could not be easily fixed. If DIR/.#FILE is a non-symlink file, Emacs now does not create a lock file for DIR/FILE; that is, DIR/FILE is no longer partly protected by a lock if DIR/.#FILE is a non-symlink file ("partly" because the locking mechanism was never reliable in that case). This patch fixes this and other bugs discovered by a code inspection that was prompted by . Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows, to avoid interoperability problems between the MS-Windows and non-MS-Windows implementations. MS-Windows and non-MS-Windows instances of Emacs now ignore each others' locks. * filelock.c (defined_WINDOWSNT): New constant. (MAKE_LOCK_NAME, fill_in_lock_file_name): Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE regular files on MS-Windows hosts. (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p): Use SAFE_ALLOCA to avoid problems with long file names. (MAX_LFINFO): Now a local constant, not a global macro. (IS_LOCK_FILE): Remove. (lock_file_1): Don't inspect errno if symlink call succeeds; that's not portable. (lock_file): Document that this function can return if lock creation fails. (lock_file): Don't access freed storage. 2013-03-02 Andreas Schwab * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734) 2013-03-02 Paul Eggert * textprop.c: Use bool for booleans. (validate_interval_range, Fadd_text_properties) (Fremove_text_properties): Prefer bool to int when either works. 2013-03-02 Eli Zaretskii * textprop.c (Fadd_text_properties, Fremove_text_properties): If the interval tree changes as a side effect of calling modify_region, re-do processing starting from the call to validate_interval_range. (Bug#13743) 2013-02-28 Eli Zaretskii * w32.c (sys_open): Don't reset the flags for FD in fd_info[]. (Bug#13546). 2013-02-27 Eli Zaretskii * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with _SH_DENYRW flag, instead of emacs_open, to deny any other process access to the lock file until it is written and closed. (Bug#13807) 2013-02-27 Paul Eggert * callint.c (Qcall_interactively): * macros.c (Qexecute_kbd_macro): Now static. 2013-02-26 Bastien Guerry * window.c (Frecenter): Tiny docstring enhancement. 2013-02-26 Paul Eggert Minor textprop integer cleanup. * intervals.h, textprop.c (add_text_properties_from_list): Return void, not int, since nobody uses the return value. * textprop.c (validate_plist, add_properties, remove_properties) (Fadd_text_properties): Don't assume list length fits in int. (interval_has_all_properties, interval_has_some_properties) (interval_has_some_properties_list, add_properties, remove_properties) (Fadd_text_properties, Fremove_text_properties) (Fremove_list_of_text_properties, text_property_stickiness): Use bool for booleans. (Fadd_text_properties, Fremove_text_properties): (Fremove_list_of_text_properties): Reindent do-while as per GNU style. 2013-02-25 Eli Zaretskii Implement CLASH_DETECTION for MS-Windows. * filelock.c [WINDOWSNT]: Include w32.h. (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime function of that name. Up-case the macro arguments. (IS_LOCK_FILE): New macro. (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK. (create_lock_file): New function, with body extracted from lock_file_1. [WINDOWSNT]: Implement lock files by writing a regular file with the lock information as its contents. (read_lock_data): New function, on Posix platforms just calls emacs_readlinkat. [WINDOWSNT]: Read the lock info from the file. (current_lock_owner): Call read_lock_data instead of calling emacs_readlinkat directly. (lock_file) [WINDOWSNT]: Run the file name through dostounix_filename. * w32proc.c (sys_kill): Support the case of SIG = 0, in which case just check if the process by that PID exists. * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is also present, as doing so will fail to error out if the file already exists. * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h. * textprop.c (Fadd_text_properties, Fremove_text_properties) (Fremove_list_of_text_properties): Skip all of the intervals in the region between START and END that already have resp. don't have the requested properties, not just the first one. Add assertions that the loop afterwards always modifies the properties. (Bug#13743) 2013-02-25 Stefan Monnier * callint.c (Fcall_interactively): Use the right lexical environment for `interactive' specs (bug#13811). * eval.c (Feval): Accept a lexical environment. 2013-02-25 Paul Eggert Simplify data_start configuration (Bug#13783). This is a followon simplification to the fix for Bug#13650. * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD) (START_FILES): Remove. All uses removed. (otherobj): Remove $(VMLIMIT_OBJ), as it's now first. (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first. (buildobj.h): Use it. ($(ALLOBJS)): Depend on globals.h.

(exceeds_lisp_ptr): New function, replacing the old EXCEEDS_LISP_PTR macro. All uses changed. (check_memory_limits): Simplify and remove casts. (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove. (memory_warnings): Use data_start instead of start_of_data. 2013-02-24 Andreas Schwab * xdisp.c (set_message): Only check for debug-on-message if STRING is a string.

Reported by Eli Zaretskii in and diagnosed by Andreas Schwab in . 2013-02-22 Paul Eggert Assume C89 or better. * ralloc.c (SIZE, POINTER, NIL): * vm-limit.c (POINTER): Remove, replacing all uses with C89 equivalents. These old symbols were present only for porting to pre-C89 platforms. 2013-02-22 Claudio Bley * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop. This avoids warning messages reported as part of Bug#13546. 2013-02-21 Ken Brown * sheap.c (report_sheap_usage): Fix arguments of message1_no_log. 2013-02-20 Stefan Monnier * sheap.c (report_sheap_usage): Prefer message1_nolog. * keyboard.c (Qcommand_execute): New var.

Break long line. * lisp.h (message_dolog, compile_pattern): Adjust prototype. * print.c (PRINTDECLARE, print_object): * search.c (compile_pattern, fast_looking_at, search_buffer): (simple_search, boyer_moore, Freplace_match): * xdisp.c (c_string_pos, number_of_chars, message_dolog): (get_overlay_arrow_glyph_row, display_mode_element): (decode_mode_spec_coding, message3): * xfaces.c (face_at_string_position): Use bool for booleans. Adjust comments. 2013-02-15 Paul Eggert Fix AIX port (Bug#13650). * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]: Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set, was #undeffed earlier, so it cannot be used as a macro here. Use the constant and not the macro. 2013-02-15 Eli Zaretskii * w32proc.c (new_child): If no vacant slots are found in child_procs[], make another pass looking for slots whose process has exited or died. (Bug#13546) * w32.c (sys_pipe): When failing due to file descriptors above MAXDESC, set errno to EMFILE. (_sys_read_ahead): Update cp->status when failing to read serial communications input, so that the status doesn't stay at STATUS_READ_IN_PROGRESS.

With this, it should be as good as it was in 23.3, though it's still pretty bad: the dumped emacs does not run. See Mark Fleishman in https://lists.gnu.org/r/help-gnu-emacs/2011-04/msg00287.html * unexaix.c (start_of_text): Remove. (_data, _text): Declare as char[], not int, as AIX manual suggests. (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr) (orig_load_scnptr, orig_data_scnptr): Now off_t, not long, since they are file offsets. (make_hdr): Use _data, not start_of_data (). This is the key part of the fix. (make_hdr, unrelocate_symbols): Use off_t for file offsets. (unrelocate_symbols): Cast pointers to intptr_t, not to ulong. * pre-crt0.c (data_start): Initialize to 1. This ports to compilers that optimize the external declaration 'int x = 0;' as if it were 'int x;' to shrink the executable. Improve AIX port (Bug#13650). This doesn't fix the bug, but it makes progress: Emacs builds now. * unexaix.c: Include inttypes.h, stdarg.h. (report_error, report_error_1): Mark as _Noreturn. (report_error): Don't report the wrong errno. (report_error_1): Now varargs. All callers changed. (make_hdr): Use uintptr_t, not unsigned, when converting pointers to unsigned. Don't use ADDR_CORRECT, as it no longer exists. (write_ptr): Use %p to print address rather than %lx and a cast to unsigned long. Grow buffer a bit, to be safer. 2013-02-13 Eli Zaretskii * bidi.c (bidi_resolve_neutral): After finding the next non-neutral character, accept NEUTRAL_ON type as well, because directional control characters, such as LRE and RLE, have their type converted to that by bidi_resolve_weak. This avoids aborts when LRE/RLE follows a run of neutrals. (bidi_move_to_visually_next): Assert that return value of bidi_peek_at_next_level is non-negative. Negative values will cause an infloop. 2013-02-13 Paul Eggert Minor getenv-related fixes. * callproc.c (Fcall_process_region) [!DOS_NT]: Avoid unnecessary duplicate call to getenv. * callproc.c (init_callproc): * dispnew.c (init_display): * sysdep.c (sys_subshell): Omit unnecessary cast of getenv or egetenv. 2013-02-13 Juanma Barranquero * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)): Update dependencies. 2013-02-12 Eli Zaretskii * xdisp.c (redisplay_internal): Don't set w->region_showing to the marker's position. (display_line): Set w->region_showing to the value of it->region_beg_charpos, not to -1. This fixes redisplay optimization when cursor is moved up after M->. (Bug#13623) (Bug#13626) (try_scrolling): Scroll text up more if point is too close to ZV and inside the scroll margin. This makes sure point is moved outside the scroll margin in these cases. * window.h (struct window): region_showing can no longer be negative. 2013-02-11 Paul Eggert Tune by using memchr and memrchr. * doc.c (Fsnarf_documentation): * fileio.c (Fsubstitute_in_file_name): * search.c (find_newline, scan_newline): * xdisp.c (pos_visible_p, display_count_lines): Use memchr and memrchr rather than scanning byte-by-byte. * search.c (find_newline): Rename from scan_buffer. Omit first arg TARGET, as it's always '\n'. All callers changed. Clean up read_key_sequence a tiny bit more. * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]: (read_key_sequence): Remove unused locals. 2013-02-11 Stefan Monnier Clean up read_key_sequence a bit; reread active keymaps after first event. * keyboard.c (read_char, read_char_x_menu_prompt) (read_char_minibuf_menu_prompt): Replace nmaps+maps with a single `map' arg. (follow_key): Operate on a single map. (active_maps): New function. (test_undefined): Also return true for nil bindings. (read_key_sequence): Use active_maps to replace the arrays of keymaps with a single (composed) keymap. Remember `first_event' to choose the right set of active keymaps. Recompute the set of keymaps after receiving the first event. Remove GOBBLE_FIRST_EVENT. (syms_of_keyboard): Remove inhibit_local_menu_bar_menus. * keyboard.h (read_char): Update declaration. * lread.c (read_filtered_event): Adjust call to read_char. 2013-02-11 Eli Zaretskii * xdisp.c (move_it_vertically_backward, move_it_by_lines): Don't use the limitation on backwards movement when lines are truncated in the window. (Bug#13675) 2013-02-11 Dmitry Antipov * marker.c (set_marker_internal): If desired position is passed as a marker, avoid call to buf_charpos_to_bytepos. * window.c (Fset_window_point): Omit redundant type checking. (Fset_window_start): Likewise. Format comment. (window_scroll_pixel_based): Use set_marker_restricted_both with character and byte positions obtained from an iterator. (Fset_window_configuration): Use set_marker_restricted_both. * xdisp.c (message_dolog): Likewise. 2013-02-10 Eli Zaretskii * xdisp.c (move_it_vertically_backward, move_it_by_lines): When text lines are longer than window's screen lines, don't move back too far. This speeds up some redisplay operations. (Bug#13675) 2013-02-10 Dmitry Antipov * syntax.c (scan_sexps_forward): Fix byte position calculation Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change. 2013-02-10 Paul Eggert * fileio.c (Fexpand_file_name): Omit confusing pointer comparison that was not needed. 2013-02-09 Paul Eggert Minor hashing refactoring. * fns.c (SXHASH_REDUCE): Move to lisp.h. (sxhash_float): Return EMACS_UINT, for consistency with the other hash functions. * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a non-static inline function and therefore can't use static vars. (SXHASH_REDUCE): Move here from fns.c, and make it inline. * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent with the other hash functions. 2013-02-09 Eli Zaretskii * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the XXXXXX part of the temporary file pattern is not downcased even when w32-downcase-file-names is non-nil. (Bug#13661) * xdisp.c (decode_mode_spec): Remove handling of %t. * msdos.c (careadlinkatcwd): Remove. 2013-02-08 Stefan Monnier * lread.c (skip_dyn_bytes): New function (bug#12598). (read1): Use it. Use getc instead of READCHAR to read bytes. (load_each_byte): Remove. Update users. 2013-02-08 Dmitry Antipov * search.c (scan_buffer): Calculate end byte position just once. (scan_newline): Do not recalculate start_byte. (search_command): Use eassert. * syntax.c (struct lisp_parse_state): New member location_byte. (scan_sexps_forward): Record from_byte and avoid redundant character to byte position calculation ... (Fparse_partial_sexp): ... here. Break too long line. 2013-02-08 Dmitry Antipov * lisp.h (make_uninit_vector): New function. * alloc.c (Fvector, Fmake_byte_code): * ccl.c (Fregister_ccl_program): * charset.c (Fdefine_charset_internal, define_charset_internal): * coding.c (make_subsidiaries, Fdefine_coding_system_internal): * composite.c (syms_of_composite): * font.c (Fquery_font, Ffont_info, syms_of_font): * fontset.c (FONT_DEF_NEW, Fset_fontset_font): * ftfont.c (ftfont_shape_by_flt): * indent.c (recompute_width_table): * nsselect.m (clean_local_selection_data): * syntax.c (init_syntax_once): * w32unsubscribe.c (uniscribe_shape): * window.c (Fcurrent_window_configuration): * xfaces.c (Fx_family_fonts): * xselect.c (selection_data_to_lisp_data): Use it. 2013-02-07 Dmitry Antipov * coding.c (Fdefine_coding_system_internal): Use AREF where argument is known to be a vector. * fns.c (Flocale_info): Likewise for ASET. * xselect.c (selection_data_to_lisp_data): Likewise for ASET. * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF. 2013-02-05 Jan Djärv * nsmenu.m (update_frame_tool_bar): Check for negative tool bar height. * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7. (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and updateCollectionBehaviour. * nsterm.m (NEW_STYLE_FS): Remove. (ns_last_use_native_fullscreen): New variable. (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen. (x_set_window_size): Do not take title bar and tool bar into account if isFullscreen returns YES. (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen. (check_native_fs): New function. (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS. (ns_term_init): Remove NEW_STYLE_FS. (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar and tool bar if isFullscreen returns NO. (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative. (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS with HAVE_NATIVE_FS. (window:willUseFullScreenPresentationOptions:): New method. (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative. Hide toolbar if not enabled (Bug#13444). (windowDidExitFullScreen:): Call updateCollectionBehaviour. Restore tool bar if enabled, hide it otherwise (Bug#13444). (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods. (toggleFullScreen:): If fs_is_native, call toggleFullScreen on window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0. Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs. (syms_of_nsterm): Add ns-use-native-fullscreen. 2013-02-04 Paul Eggert * fileio.c (Qchoose_write_coding_system): Now static. 2013-02-04 Eli Zaretskii * xdisp.c (window_buffer_changed): region_showing can be negative, which still means region is being displayed. (redisplay_internal): Resurrect code that forced redisplay of the whole window when showing region and the mark has changed. Record the new mark position to allow redisplay optimizations. (display_line): If it->region_beg_charpos is non-zero, set the window's region_showing member to -1. (Bug#13623) (Bug#13626) * window.h (struct window) : Declare ptrdiff_t, not bitfield of 1 bit. 2013-02-03 Daniel Colascione * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that daemon mode works on cygw32 when Emacs is installed and not just during development. 2013-02-02 Paul Eggert Avoid file time stamp bug on MS-Windows (Bug#13149). * fileio.c (Fwrite_region): Don't use the heuristic on empty files, as FAT32 doesn't update time stamps when truncating them. Also, check that a file time stamp is not a multiple of 100 ns; this should catch all instances of the problem on MS-Windows, as its native file system resolution is 100 ns or worse, and checking for a non-multiple of 100 ns should impose only a small overhead on systems with ns resolution. 2013-02-02 Eli Zaretskii Avoid encoding file names on MS-Windows when they need to be run through dostounix_filename. * w32.c (normalize_filename): Accept an additional argument MULTIBYTE; if non-zero, traverse the file name by bytes and don't downcase it even if w32-downcase-file-names is non-nil. (dostounix_filename): Accept an additional argument MULTIBYTE and pass it to normalize_filename. (emacs_root_dir): Adjust. * msdos.h (dostounix_filename): Adjust prototype. * w32.h (dostounix_filename): Adjust prototype. * msdos.c (dostounix_filename): Accept an additional argument and ignore it. (init_environment): Adjust callers of dostounix_filename. * fileio.c (Ffile_name_directory, file_name_as_directory) (directory_file_name, Fexpand_file_name) (Fsubstitute_in_file_name): [DOS_NT] Adjust call to dostounix_filename. [WINDOWSNT]: Downcase file names if w32-downcase-file-names is non-nil. (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment variables, as egetenv is case-insensitive for DOS_NT. * dired.c (file_name_completion): Don't call Fdirectory_file_name with an encoded file name. * w32proc.c (Fw32_short_file_name, Fw32_long_file_name): Adjust calls to dostounix_filename. * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename. * unexw32.c (unexec): Adjust call to dostounix_filename. * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename. * emacs.c (decode_env_path) [DOS_NT]: Adjust call to dostounix_filename. * callproc.c (Fcall_process) [MSDOS]: Adjust call to dostounix_filename. * callproc.c (Fcall_process): Make sure program name in PATH and new_argv[0] is encoded, if needed. Otherwise, un-encoded string is passed to exec/spawnve, which fails unless the file-name encoding is UTF-8. * w32proc.c (sys_spawnve): Make sure escape_char is initialized, even if w32-quote-process-args is nil. 2013-02-01 Paul Eggert Fix timestamp bug when write-region appends nothing (Bug#13149). * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used, the file's time stamp doesn't change if Emacs happens to write nothing to the file, and on a buggy file system this could cause Emacs to incorrectly infer that the file system doesn't have the bug. Avoid this problem by inhibiting the inference in this case. 2013-02-01 Dmitry Antipov * window.h (struct window): Convert base_line_number, base_line_pos and column_number_displayed members from Lisp_Object to ptrdiff_t. Convert region_showing member from Lisp_Object to bitfield. Remove sequence_number member. Adjust comments. * window.c (sequence_number): Remove. (make_window): Initialize column_number_displayed. * print.c (print_object): Follow the printed representation of frames and print window pointer to distinguish between windows. (adjust_window_count): Invalidate base_line_pos. Adjust comment. * xdisp.c (wset_base_line_number, wset_base_line_pos) (wset_column_number_displayed, wset_region_showing): Remove. (window_buffer_changed, mode_line_update_needed, redisplay_internal) (try_scrolling, try_cursor_movement, redisplay_window) (try_window_reusing_current_matrix, try_window_id, display_line) (display_mode_lines, decode_mode_spec): Adjust users. * .gdbinit (pwinx): Do not print sequence_number. 2013-02-01 Paul Eggert Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539). * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove. * dired.c: Include . (open_directory): New function, which uses open and fdopendir rather than opendir. DOS_NT platforms still use opendir, though. (directory_files_internal, file_name_completion): Use it. (file_attributes): New function, with most of the old Ffile_attributes. (directory_files_internal, Ffile_attributes): Use it. (file_attributes, file_name_completion_stat): First arg is now fd, not dir name. All uses changed. Use fstatat rather than lstat + stat. (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p. * fileio.c: Include , . (emacs_readlinkat): New function, with much of the old Ffile_symlink_p, but with an fd argument for speed. It uses readlinkat rather than careadlinkatcwd, so that it need not assume the working directory. (Ffile_symlink_p): Use it. * filelock.c (current_lock_owner): Use emacs_readlinkat rather than emacs_readlink. * lisp.h (emacs_readlinkat): New decl. (READLINK_BUFSIZE, emacs_readlink): Remove. * sysdep.c: Do not include , . (emacs_norealloc_allocator, emacs_readlink): Remove. This stuff is moved to fileio.c. * w32.c (fstatat, readlinkat): New functions. (careadlinkat): Don't check that fd == AT_FDCWD. (careadlinkatcwd): Remove; no longer needed. 2013-01-31 Glenn Morris * fileio.c (choose_write_coding_system): Make it callable from Lisp. (Fwrite_region): Update for new choose_write_coding_system args. Move the last piece of choose_write_coding_system here. (Bug#13522) (syms_of_fileio): Add choose-write-coding-system. 2013-01-30 Eli Zaretskii * w32.c (sys_open): Zero out the flags for the new file descriptor. (sys_close): Zero out the flags for the file descriptor before closing it. (Bug#13546) * w32.c (parse_root, get_volume_info, readdir, read_unc_volume) (logon_network_drive, stat_worker, symlink, chase_symlinks): Use CharNextExA and CharPrevExA to iterate over file names encoded in DBCS. (Bug#13553) * w32.c (w32_get_long_filename, init_environment, readlink): Support file names encoded in DBCS codepages. (readlink): Use the current file-name-coding-system, not the ANSI codepage, to decode and handle targets of symlinks. 2013-01-28 Eli Zaretskii * w32.c (opendir): Now accepts a 'const char *'. 2013-01-28 Dmitry Antipov Remove obsolete redisplay code. See the discussion at https://lists.gnu.org/r/emacs-devel/2013-01/msg00576.html. * dispnew.c (preemption_period, preemption_next_check): Remove. (Vredisplay_preemption_period): Likewise. (update_frame, update_single_window, update_window, update_frame_1): Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not used, following the 2012-06-22 change. 2013-01-25 Eli Zaretskii * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540) 2013-01-25 Dmitry Antipov * font.c (num_fonts): Remove the leftover from old debugging code. Adjust comment style here and there. * insdel.c (insert_1): Remove. * lisp.h (insert_1): Remove prototype. * xdisp.c (message_dolog): Adjust users to call insert_1_both. 2013-01-25 Eli Zaretskii * w32.c (max_filename_mbslen): New function. (normalize_filename, readdir): Use it to detect locales where ANSI encoding of file names uses a double-byte character set (DBCS). If a DBCS encoding is used, advance by characters using CharNextExA, instead of incrementing a 'char *' pointer. Use _mbslwr instead of _strlwr. (Bug#13515) * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial request of memory reservation to 1.7GB. (Bug#13065) 2013-01-25 Andreas Schwab * coding.c (detect_coding_iso_2022): Move back mis-reordered code at check_extra_latin label. (Bug#13505) 2013-01-24 Dmitry Antipov * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script): Avoid redundant calls to strlen. 2013-01-24 Dmitry Antipov Drop async_visible and async_iconified fields of struct frame. This is possible because async input is gone; for details, see https://lists.gnu.org/r/emacs-devel/2012-12/msg00734.html. * frame.h (struct frame): Remove async_visible and async_iconified members, convert garbaged to unsigned bitfield. Adjust comments. (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users. (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros. * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c: Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED, FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate. * w32term.c: Ditto. (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT properly. Likewise for obscured. * xterm.c: Ditto. (handle_one_xevent): Save visible state to generate ICONIFY_EVENT properly. * nsterm.m: Ditto. (windowDidDeminiaturize): Generate DEICONIFY_EVENT. 2013-01-24 Dmitry Antipov * insdel.c (prepare_to_modify_buffer): Revert last change as suggested in https://lists.gnu.org/r/emacs-devel/2013-01/msg00555.html. 2013-01-23 Stefan Monnier * xdisp.c (message2, message2_nolog): Remove functions. (message3, message3_nolog): Extract nbytes and multibyteness directly from the string. Change all callers. (message3_nolog): Don't set message_enable_multibyte since set_message will reset it anyway. (message1, message1_nolog): Use message3. (vmessage): Use a stack allocated buffer rather than f->message_buf. (with_echo_area_buffer): Remove last two arguments. Update all callers. (set_message): Drop all but the second arg, which has to be a string. (set_message_1): Simplify now that we know that a1 is NULL and the second arg is a string. * frame.h (struct frame): Remove `message_buf' field. Use glyphs_initialized_p instead. (FRAME_MESSAGE_BUF): Remove macro. * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2. * lisp.h (message2, message2_nolog): Remove declarations. (message3, message3_nolog): Update declarations. * keyboard.c (read_char_minibuf_menu_text) (read_char_minibuf_menu_width): Remove vars. (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as to correctly handle multibyte strings. * frame.c (delete_frame): Don't free message_buf any more. * editfns.c (message_text, message_length): Remove vars. (Fmessage_box): Don't copy the Lisp string's bytes any longer. * fileio.c (auto_save_error): Use message3 instead of message2. * dispnew.c (adjust_frame_message_buffer): Remove function. 2013-01-23 Eli Zaretskii * w32term.c (w32fullscreen_hook): Account correctly for the screen real estate used for the tool bar and the menu bar. 2013-01-23 Dmitry Antipov * insdel.c (prepare_to_modify_buffer): Force redisplay if hidden buffer is prepared to modification (Bug#13164). 2013-01-22 Dmitry Antipov * window.h (struct window): Change window_end_valid member from Lisp_Object to a bitfield. Adjust comments. (wset_window_end_valid): Remove. * window.c (adjust_window_count): Clear window_end_valid. (Fwindow_end): Adjust user. Remove ancient #if 0 code. (Fwindow_line_height, set_window_buffer, Frecenter) (Fsplit_window_internal, Fdelete_other_windows_internal) (Fset_window_fringes, Fset_window_scroll_bars): Adjust users. * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise. * xdisp.c (check_window_end, reconsider_clip_changes) (redisplay_internal, mark_window_display_accurate_1, redisplay_window) (try_window, try_window_reusing_current_matrix, note_mouse_highlight) (find_first_unchanged_at_end_row, try_window_id): Likewise. 2013-01-22 Dmitry Antipov * xdisp.c (mark_window_display_accurate): Simplify the loop assuming that the only one of vchild, hchild or buffer window slots is non-nil. Call mark_window_display_accurate_1 for the leaf windows only. (mark_window_display_accurate_1): Always assume leaf window. Adjust comment. 2013-01-22 Paul Eggert * emacs.c (Qkill_emacs_hook): Now static. * fileio.c (Finsert_file_contents): Simplify. Remove unnecessary assignments and tests. 2013-01-21 Eli Zaretskii * w32.c (acl_set_file): Don't test for errors unless set_file_security returns FALSE. Avoids spurious errors when saving files. 2013-01-21 Dmitry Antipov * fileio.c (Finsert_file_contents): Revert code introduced at 2013-01-18 in favor of the simpler and generally better fix. Save stack space by removing 'buffer' and reusing 'read_buf' where appropriate. 2013-01-19 Paul Eggert * lisp.h (eabs): Define unconditionally (Bug#13419). The old "#if !defined (eabs)" was an unnecessary revenant of back when this macro was called "abs". Document 'eabs' better. 2013-01-19 Glenn Morris * fns.c (Frandom): Doc fix. 2013-01-19 Eli Zaretskii * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid segfault when there are lots of overlays. * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault when there are lots of overlays. See https://lists.gnu.org/r/emacs-devel/2013-01/msg00421.html for the details and a way to reproduce. 2013-01-19 Paul Eggert * fileio.c: Use O_APPEND to append. This corresponds better to the natural interpretation of "append", and avoids the need to open the output file twice, or to invoke lseek when APPEND is neither nil nor a number. This relies on POSIX 1003.1-1988 or later, which is OK nowadays. (Fwrite_region): Simplify. Use O_APPEND instead of opening the file possibly twice, and lseeking to its end; this avoids the need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC at the same time: the combination is never needed and apparently it doesn't work with DOS_NT. Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149). * fileio.c (Fwrite_region): Use O_BINARY in checking code, too. Allow floating-point file offsets. Problem reported by Vitalie Spinu in . * fileio.c (emacs_lseek): Remove. (file_offset): New function. (Finsert_file_contents, Fwrite_region): Use it. 2013-01-19 Chong Yidong * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid aborting on Fsignal (Bug#13289). 2013-01-19 Eli Zaretskii * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from set_file_security as failure due to insufficient privileges. Reported by Fabrice Popineau . (fstat): Return owner and group like 'stat' and 'lstat' do. 2013-01-19 Paul Eggert Work around bug in CIFS and vboxsf file systems (Bug#13149). The bug was observed on Ubuntu operating inside a virtual machine, editing files mounted via CIFS or vboxsf from the MS Windows 7 host. The workaround introduces a race condition on non-buggy hosts, but it's an unlikely race and anyway there's a nearly identical nearby race that can't be fixed. * fileio.c (valid_timestamp_file_system, timestamp_file_system): New static vars. (Fwrite_region): Test for file system time stamp bug. (init_fileio): New function. * lisp.h (init_fileio): Declare it. * emacs.c (main): Call it. * fileio.c (Finsert_file_contents): Simplify new diagnostic and make it more consistent with other stat-failure diagnostics. 2013-01-18 Dmitry Antipov Fix crash when inserting data from non-regular files. See https://lists.gnu.org/r/emacs-devel/2013-01/msg00406.html for the error description produced by valgrind. * fileio.c (read_non_regular): Rename to read_contents. Free Lisp_Save_Value object used to pass parameters. (read_non_regular_quit): Rename to read_contents_quit. (Finsert_file_contents): Redesign internal file reading loop to adjust gap and end positions after each read and so help make_gap to work properly. Do not signal an I/O error too early and so do not leave not yet decoded characters in a buffer, which was the reason of redisplay crash. Use list2 to build return value. Adjust comments. 2013-01-17 Paul Eggert Close a race when statting and reading files (Bug#13149). * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open. This avoids a race if the file is renamed between stat and open. This race is not the problem originally noted in Bug#13149; see and later messages in the thread. 2013-01-17 Dmitry Antipov * lisp.h (toplevel): Add comment about using Lisp_Save_Value objects, related functions and macros.

(mark_object): Likewise. * editfns.c (save_excursion_save): Pack everything within Lisp_Save_Value and so avoid xmalloc. (save_excursion_restore): Adjust to match new layout. Use free_misc because we do not allocate extra memory any more. Add eassert. * print.c (print_object): New code to print Lisp_Save_Value. Do not rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments. * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c, * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c: Use XSAVE_POINTER and XSAVE_INTEGER where appropriate. 2013-01-13 Jan Djärv * nsfont.m (LCD_SMOOTHING_MARGIN): New define.

(move_gap_both): Add eassert. * editfns.c (Ftranspose_regions): Tweak to use move_gap_both. * xml.c (parse_region): Likewise. 2013-01-11 Paul Eggert emacsclient -t should not suspend Emacs server (Bug#13387) * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal): New functions. * term.c (init_tty): Use them instead of rolling our own code. * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this switches from 'signal' to 'pthread_sigmask', which is safer in multithreaded applications. * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY, which has already arranged for that. (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY. This is the main part of the bug fix. 2013-01-10 Rainer Orth (tiny change) * gtkutil.c (xg_initialize): Add ifdef HAVE_FREETYPE around x_last_font_name (Bug#13403). 2013-01-10 Dmitry Antipov Omit buffer_slot_type_mismatch and use generic predicates to enforce the type of per-buffer values where appropriate. * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to predicate, which is how it's really used now. Adjust comment. * buffer.h (buffer_slot_type_mismatch): Remove prototype. * buffer.c (buffer_slot_type_mismatch): Remove. (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to predicate. Adjust comment. (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for fill-column, left-margin, tab-width, buffer-saved-size, left-margin-width, right-margin-width, left-fringe-width, right-fringe-width, scroll-bar-width and buffer-display-count. Use Qstringp for default-directory, buffer-file-name, buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for line-spacing. * data.c (store_symval_forwarding): Adjust to call the predicate. 2013-01-09 Juanma Barranquero * w32.c (get_name_and_id, acl_set_file): * w32term.c (w32fullscreen_hook): Remove unused local variables. 2013-01-09 Dmitry Antipov * lisp.h (make_gap_1): New prototype. * buffer.h (GAP_BYTES_DFL, GAP_BYTES_MIN): New macros for the special gap size values. * editfns.c (Fbuffer_size): Rename from Fbufsize to fit the common naming convention. (syms_of_editfns): Adjust defsubr. Drop commented-out obsolete code. * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment. (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment. (make_gap_1): New function to adjust the gap of any buffer. * coding.c (coding_alloc_by_making_gap): Use it. * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE, GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment. 2013-01-08 Juri Linkov * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case of (supports :underline (:style wave)). (Bug#13000) 2013-01-08 Aaron S. Hawley * undo.c (Fprimitive_undo): Move to simple.el. (syms_of_undo): Remove declarations for Sprimitive_undo. 2013-01-08 Stefan Monnier * keyboard.c (echo_add_key): Rename from echo_add_char. 2013-01-06 Chong Yidong * keyboard.c (echo_add_char): New function, factored out from echo_char. Don't add a space if the previous echo string was empty (Bug#13255). (echo_char): Use it. (read_key_sequence): When echoing mock input, ensure that the trailing dash is properly added. 2013-01-05 Eli Zaretskii * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead of a non-portable "t" to print ptrdiff_t values. Allow up to 9 digits for buffer positions, before misalignment starts. Display "0" for integer "object" field. (dump_glyph_row): Adapt the header line to changes in dump_glyph. Display the newline glyph more unambiguously. 2013-01-04 YAMAMOTO Mitsuharu * nsterm.m (ns_draw_underwave): * w32term.c (w32_draw_underwave): * xterm.c (x_draw_underwave): Make underwave look more triangular and also degrade gracefully for small fonts. (Bug#13000) * nsterm.m (ns_draw_text_decoration): * w32term.c (x_draw_glyph_string): * xterm.c (x_draw_glyph_string): Don't use previous underline thickness and position if previous underline type is underwave. 2013-01-04 Stefan Monnier * fileio.c (Ffile_acl): Undocument return format. 2013-01-02 Glenn Morris * keymap.c (Fkey_description): Doc fix. (Bug#13323) 2013-01-02 Paul Eggert Simplify via eabs. * dired.c (file_name_completion): * doc.c (get_doc_string): * floatfns.c (round2): * font.c (font_score, font_delete_unmatched): * fringe.c (compute_fringe_widths): * lread.c (read_list): * minibuf.c (Ftry_completion): * term.c (tty_ins_del_lines): * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1): Use eabs (x) rather than open-coding it as (x < 0 ? -x : x). 2012-12-31 Eli Zaretskii * w32.c (unsetenv): Set up the string passed to _putenv correctly. See https://lists.gnu.org/r/emacs-devel/2012-12/msg00863.html for the bug this caused. 2012-12-30 Paul Eggert * coding.c (Qmac): Now static. 2012-12-30 Jan Djärv * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro. (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of handlebox_widget. Set toolbar_in_hbox to false/true, set toolbar_is_packed to true. (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET. (update_frame_tool_bar): Check toolbar_is_packed for packing. Show all on TOOLBAR_TOP_WIDGET. (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned by TOOLBAR_TOP_WIDGET. (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET. Check toolbar_is_packed. (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on HAVE_GTK_TEAROFF_MENU_ITEM_NEW. (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return false. (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW. (xg_update_menubar): Update title only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW. (xg_update_submenu): Skip tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW. (xg_initialize): Initialize xg_detached_menus only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW. * xterm.h (struct x_output): Surround handlebox_widget with #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new, toolbar_in_hbox is bool. 2012-12-30 Andreas Schwab * Makefile.in (TEMACS_LDFLAGS2): Remove.

(Bug#13277) 2012-12-29 Eli Zaretskii * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if file's SELinux context or ACLs successfully set, nil otherwise. (Bug#13298) (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails. * w32proc.c (reader_thread): Avoid passing NULL handles to SetEvent and WaitForSingleObject. 2012-12-28 Paul Eggert Port EXTERNALLY_VISIBLE to Clang 3.2. * conf_post.h (__has_attribute): New macro.

This ports to Clang 3.2. 2012-12-27 Glenn Morris * cygw32.c (Fcygwin_convert_file_name_to_windows) (Fcygwin_convert_file_name_from_windows): Doc fixes. 2012-12-27 Eli Zaretskii * fileio.c (file_name_as_directory, directory_file_name): Accept an additional argument MULTIBYTE to indicate whether the input C came from a multibyte or a unibyte Lisp string; all callers adjusted. Don't assume the input string is always multibyte. (Bug#13262) (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly: don't ENCODE_FILE them, and return a unibyte string if the input was unibyte. (Fexpand_file_name): Don't mix unibyte with multibyte strings, and don't assume the input strings will always be multibyte. If the input strings are multibyte, decode strings obtained from C library functions. 2012-12-26 Dmitry Antipov * lisp.h (toplevel): Add two notices to the comment about defining a new Lisp data type. * print.c (print_object): If Lisp_Save_Value object's pointer is the address of a memory area containing Lisp_Objects, try to print them. * alloc.c (valid_lisp_object_p): Adjust comment. 2012-12-26 Dmitry Antipov * keyboard.c (record_asynch_buffer_change): Initialize an event only if it's really needed. * frame.h (enum output_method): Remove output_mac member since it's a leftover from the deleted code. * frame.c (Fframep): Adjust user here ... * terminal.c (Fterminal_live_p): ... and here. * coding.c (Qmac): Now here because it's only used to denote end-of-line encoding type. (syms_of_coding): DEFSYM it. * frame.h (Qmac): Remove duplicated declaration. 2012-12-26 Paul Eggert * window.c (select_window_1): Now static, since it's used only here. 2012-12-25 Eli Zaretskii * window.c (window_body_cols): Subtract display margins from the window body width on TTYs as well. See https://lists.gnu.org/r/help-gnu-emacs/2012-12/msg00317.html for the original report. 2012-12-25 Dmitry Antipov * xdisp.c (redisplay_window): Remove inner local variable because the outer shadowed one has the same meaning. * xterm.h (struct x_output): Remove toolbar_detached member since it's set but never used. * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback) (xg_create_tool_bar): Adjust users. 2012-12-24 Dmitry Antipov * buffer.h (BUF_COMPACT): New macro to follow the common style. * buffer.c (Fget_buffer_create): Use it to set compact field of struct buffer_text to avoid accessing an uninitialized value when compact_buffer is called for the first time. (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF. (Fset_buffer_modified_p): Use buffer_window_count to check whether the buffer is displayed in some window. * xdisp.c (message_dolog): Likewise. 2012-12-23 Eli Zaretskii * w32.c (acl_set_file): If setting the file security descriptor fails, and the new DACL is identical to the existing one, silently return success. This fixes problems for users backing up their own files without having the necessary privileges for setting security descriptors. * w32proc.c (reader_thread): Do not index fd_info[] with negative values. (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR after WaitForSingleObject returns normally. This expedites reader thread shutdown when delete_child triggers it. (reap_subprocess): More accurate commentary for why we call delete_child only when cp->fd is negative. * w32.c (sys_close): Do not call delete_child on a subprocess whose handle is not yet closed. Instead, set its file descriptor to a negative value, so that reap_subprocess will call delete_child on that subprocess when its SIGCHLD arrives. This avoids closing handles used for communications between sys_select and reader_thread, which doesn't give sys_select a chance to notice that the process exited and invoke the SIGCHLD handler for it. 2012-12-23 Jan Djärv * nsfns.m (Fns_do_applescript): Run event loop until script has been executed (Bug#12969). (ns_run_ascript): Chech as_script for nil, set to nil after executing script. 2012-12-22 Martin Rudalics * window.c (Fselect_window): Reword doc-string (Bug#13248). 2012-12-22 Eli Zaretskii * w32term.c (w32fullscreen_hook): New function. (w32_create_terminal): Plug it into the terminal's fullscreen_hook. 2012-12-21 Eli Zaretskii * fileio.c (Finsert_file_contents): Doc fix. * w32proc.c (new_child, delete_child, find_child_pid): For a subprocess, consider its slot being in use as long as its process handle (procinfo.hProcess) is not NULL. This avoids reusing the slot when a new process is started immediately after killing another one, without waiting enough time for the first process to be reaped and resources allocated for it be orderly freed. (Bug#13086) Suggested by Fabrice Popineau . 2012-12-21 Chong Yidong * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231). * fns.c (Fcompare_strings): Doc fix (Bug#13081). 2012-12-21 Eli Zaretskii * w32.c (get_name_and_id): Always pass NULL as the first argument of lookup_account_sid. Avoids crashes with UNC file names that refer to DFS domains, not to specific machine names. (Bug#12621) Remove now unused argument FNAME; all callers changed. (get_file_owner_and_group): Remove now unused argument FNAME; all callers changed. 2012-12-21 Chong Yidong * editfns.c (Finsert_char): Since read-char-by-name now signals an error for invalid chars, don't check for a nil return value. 2012-12-20 Dmitry Antipov Avoid calls to CHAR_TO_BYTE if byte position is known. * editfns.c (make_buffer_string_both): Use move_gap_both. (Fbuffer_string): Use make_buffer_string_both. * marker.c (buf_charpos_to_bytepos): Convert to eassert. Adjust comment. (buf_bytepos_to_charpos): Likewise. (charpos_to_bytepos): Remove. * fileio.c (Finsert_file_contents): Use move_gap_both. * search.c (Freplace_match): Likewise. * process.c (process_send_region): Likewise. Use convenient names for byte positions. * lisp.h (charpos_to_bytepos): Remove prototype. * indent.c (scan_for_column): Use CHAR_TO_BYTE. * insdel.c (move_gap): Likewise. 2012-12-20 Paul Eggert * xdisp.c (redisplay_internal): Remove now-unused local. 2012-12-20 Stefan Monnier * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove. (redisplay_internal): Don't bother selecting the frame to get the proper value of frame-local variables (bug#13225). 2012-12-20 Dmitry Antipov * textprop.c (set_text_properties_1): Do not allow NULL interval. Rename 4th argument since it may be buffer or string. Adjust comment. * intervals.c (graft_intervals_info_buffer): Find an interval here. 2012-12-19 Dmitry Antipov * coding.c (Fdetect_coding_region): Do not check start and end with CHECK_NUMBER_COERCE_MARKER since validate_region does that itself. (code_convert_region): Likewise. 2012-12-18 Eli Zaretskii * w32.c (acl_get_file, acl_set_file): Run the file name through map_w32_filename, and resolve any symlinks in the file name, like Posix platforms do. (acl_set_file): Call revert_to_self, if any privileges were enabled. 2012-12-17 Juanma Barranquero * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O)) ($(BLD)/w32.$(O)): Update dependencies. 2012-12-17 Stefan Monnier * xdisp.c (select_frame_for_redisplay): Use select_window_1 to propagate redisplay's scrolling (if any) to the right window. (redisplay_internal): Use ensure_selected_frame. (display_mode_lines): Complete last fix. * window.c (select_window_1): New func, extracted from select_window. (select_window): Use it. * window.h (select_window_1): Declare. 2012-12-17 Eli Zaretskii Emulate Posix ACL APIs on MS-Windows. * w32.c: Include sddl.h and sys/acl.h. (SDDL_REVISION_1): Define if not already defined. (g_b_init_get_security_descriptor_dacl) (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd) (g_b_init_is_valid_security_descriptor) (g_b_init_set_file_security): New static flags.

With the 2012-12-03 fix for Bug#12980 in place, an old workaround for some of that bug's symptoms can now cause Emacs to abort. Remove the workaround. * process.c (wait_reading_process_output): Don't reraise SIGCHLD. The bug that caused SIGCHLD to get lost has been fixed, and the workaround for it can now cause Emacs to abort. 2012-12-16 Paul Eggert * sysdep.c (emacs_abort): Bump backtrace size to 40. Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in . 2012-12-16 Romain Francoise * fileio.c (Ffile_acl, Fset_file_acl): New functions. (Fcopy_file): Change last arg to `preserve_extended_attributes' and copy ACL entries of file in addition to SELinux context if set. (syms_of_fileio): Add `file-acl' and `set-file-acl'. * Makefile.in (LIBACL_LIBS): New macro. (LIBES): Use it. 2012-12-15 Paul Eggert * fileio.c (internal_delete_file): Use bool for boolean. 2012-12-15 Eli Zaretskii Fix bug #13079 on MS-Windows with temp files not being deleted. * w32.h (_child_process): New members input_file and pending_deletion.

[WINDOWSNT] If BUFFER is an integer, i.e. we are launching an asynchronous subprocess, record the name of the input file name, if any. (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to delete the file, record it as pending deletion when the subprocess exits. 2012-12-14 Eli Zaretskii * editfns.c [HAVE_PWD_H]: Include grp.h. * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h. 2012-12-14 Paul Eggert Fix permissions bugs with setgid directories etc. (Bug#13125) * dired.c (Ffile_attributes): Return t as the 9th attribute, to mark it as a placeholder. The old value was often wrong. The only user of this attribute has been changed to use file-ownership-preserved-p instead, with its new group arg. * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions. 2012-12-14 Stefan Monnier * xdisp.c (select_frame_for_redisplay, display_mode_lines): Keep selected_window and selected_frame in sync. 2012-12-14 Eli Zaretskii * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not try to get accurate owner and group information from NT file security APIs. This is to make most callers of 'stat' and 'lstat', which don't need that information, much faster. * dired.c (Ffile_attributes) [WINDOWSNT]: Set w32_stat_get_owner_group to a non-zero value, to request accurate owner and group information from 'lstat'. 2012-12-13 Paul Eggert * fileio.c (Finsert_file_contents): Don't put tail into head area, as that confuses set-auto-coding, so insist on the head-read returning the full 1024 bytes. Let lseek compute the tail offset; less work for us. Do not ignore I/O errors when reading the tail. * xdisp.c: Minor style fixes. (init_iterator): Hoist assignment out of if-expression. (markpos_of_region): Callers now test for sign, not for -1. 2012-12-13 Dmitry Antipov Minor redisplay optimization when the region length is zero. * xdisp.c (markpos_of_region): New function.

(Fverify_visited_file_modtime): Don't read uninitialized st.st_size. 2012-12-13 Paul Eggert * fileio.c (Fcopy_file): Make fstat failure as serious as open failure. fstat shouldn't fail, and if it does fail copy-file should not proceed. Remove unnecessary S_ISLNK test, as (contra the comments) this function can't copy symlinks. Improve quality of error message when attempting to copy files that are neither regular files nor directories. 2012-12-12 Dmitry Antipov * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds. * gtkutil.c (xg_set_toolkit_scroll_bar_thumb): * window.c (Frecenter): * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs): * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise. 2012-12-12 Daniel Colascione * unexcw.c (fixup_executable): Use posix_fallocate to ensure that the dumped Emacs is not a sparse file, greatly improving Cygwin "make bootstrap" performance. 2012-12-11 Michael Albinus * inotify.c (inotify_callback): Generate an Emacs event for every incoming inotify event. 2012-12-11 Eli Zaretskii * xdisp.c (handle_face_prop): Fix logic of computing it->start_of_box_run_p. (append_space_for_newline): If the glyph row is R2L, reset the iterator's end_of_box_run_p flag before prepending the space glyph. (extend_face_to_end_of_line): If the glyph row is R2L, reset the iterator's start_of_box_run_p flag before prepending the stretch. (append_glyph, produce_image_glyph, append_composite_glyph) (append_stretch_glyph, append_glyphless_glyph): Reverse the left_box_line_p and right_box_line_p flags of the glyph for R2L glyph rows. (Bug#13011) 2012-12-11 Dmitry Antipov * buffer.c (Fset_buffer_multibyte): Do not force redisplay if changed buffer is not shown in a window. * insdel.c (prepare_to_modify_buffer): Likewise. * window.c (replace_buffer_in_windows_safely): Do nothing if buffer is not shown in a window. (Fforce_window_update): Likewise if string or buffer argument is passed. 2012-12-11 Eli Zaretskii * inotify.c (Finotify_add_watch): Rename decoded_file_name to encoded_file_name, which is what it is. 2012-12-11 Dmitry Antipov Consistently use marker_position and marker_byte_position. * fringe.c (Ffringe_bitmaps_at_pos): * indent.c (Fvertical_motion): * insdel.c (prepare_to_modify_buffer): * keyboard.c (make_lispy_position): * window.c (Fwindow_end, Fpos_visible_in_window_p, unshow_buffer) (window_scroll_pixel_based, displayed_window_lines) (Fset_window_configuration): * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data) (mark_window_display_accurate_1, redisplay_window, decode_mode_spec): Replace direct access to marker fields with calls to marker_position and/or marker_byte_position. 2012-12-11 Juanma Barranquero * makefile.w32-in (SIG2STR_H): New macro. (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O)) ($(BLD)/w32notify.$(O)): Update dependencies. 2012-12-10 Daniel Colascione * w32term.c, keyboard.c: Fix build break in cygw32 by omitting Windows file notification functionality unless WINDOWSNT. * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused declarations. * w32fns.c (cache_system_info): Initialize the global hinst variable here so various initialization calls DTRT. * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables. (hinst): Remove unneeded extern declaration. (_start): Remove initialization of above variables; remove initialization of hinst, as cache_system_info now does that. * emacs.c (main): Call cache_system_info early in startup; we previously weren't calling it in Cygwin builds. * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK): Teach the autoconf build system how to compile a Windows resource file and link it to Emacs. 2012-12-10 Dmitry Antipov Per-buffer window counters. * buffer.h (struct buffer): New member window_count.

(Bug#13108) 2012-12-10 Martin Rudalics * editfns.c (Fcompare_buffer_substrings): Reword doc-string. 2012-12-10 Paul Eggert * fileio.c (Fsubstitute_in_file_name): Use ptrdiff_t, not int, for string length. 2012-12-08 Eli Zaretskii * w32.c (unsetenv): Return 0 if the input string is too long. 2012-12-08 Paul Eggert Use putenv+unsetenv instead of modifying environ directly (Bug#13070). * alloc.c (xputenv): New function. * dbusbind.c (Fdbus_init_bus): * emacs.c (main): * xterm.c (x_term_init): Use xputenv instead of setenv or putenv, to detect memory exhaustion. * editfns.c (initial_tz): Move static var decl up. (tzvalbuf_in_environ): New static var. (init_editfns): Initialize these two static vars. (Fencode_time): Don't assume arbitrary limit on EMACS_INT width. Save old TZ value on stack, if it's small. (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly; instead, use xputenv+unsetenv to set and restore TZ. (environbuf): Remove static var. All uses removed. (Fset_time_zone_rule): Do not save TZ and environ; no longer needed here. (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]: Move to inside set_time_zone_rule; they don't need file scope any more. (set_time_zone_rule): Maintain the TZ=value string separately. (syms_of_editfns): Don't initialize initial_tz; init_editfns now does it. * emacs.c (dump_tz) [HAVE_TZSET]: Now const. * lisp.h (xputenv): New decl. 2012-12-08 Fabrice Popineau * w32fns.c (emacs_abort): Don't do arithmetic on void pointers. 2012-12-08 Eli Zaretskii * w32.c (unsetenv, sys_putenv): New functions. 2012-12-08 Chong Yidong * editfns.c (Finsert_char): Make the error message more informative (Bug#12992). 2012-12-08 Paul Eggert Simplify get_lim_data. * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods. Remove USG and vlimit methods; no longer used these days. Add #error catchall just in case. Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026). Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these. * process.c [subprocesses]: Include , . (deleted_pid_list, Fdelete_process, create_process) (record_child_status_change, handle_child_signal, deliver_child_signal) (init_process_emacs, syms_of_process): Assume SIGCHLD is defined. (parse_signal): Remove. All uses removed. (abbr_to_signal): New static function.

(init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL, SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more. * syssignal.h (EMACS_KILLPG): Remove. All uses replaced by 'kill' with a negative pid. (SIGCHLD): Remove definition, as we now assume SIGCHLD. * w32proc.c (sys_kill): Support negative pids compatibly with POSIX. 2012-12-07 Paul Eggert * sysdep.c (get_child_status): Abort on internal error (Bug#13086). This will cause a production Emacs to dump core instead of infinite-looping. 2012-12-07 Dmitry Antipov * frame.c (make_frame): Do not set window's buffer to t. * window.c (Fsplit_window_internal): Likewise. Previously it was used to indicate that the window is being set up. Now we use set_window_buffer for all new windows, so the condition in ... (Fset_window_buffer): ... is always true and can be removed. 2012-12-07 Dmitry Antipov Convenient macro to check whether the buffer is hidden. * buffer.h (BUFFER_HIDDEN_P): New macro. * frame.c (make_frame): Use it. Adjust comment. * buffer.c (candidate_buffer): New function. (Fother_buffer, other_buffer_safely): Use it. 2012-12-06 Eli Zaretskii * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG if the child process is still running. Instead, exit the wait loop and return zero. (Bug#13086) 2012-12-06 Dmitry Antipov * frame.h (x_char_width, x_char_height): Remove prototypes. * w32term.h (x_char_width, x_char_height): Likewise. * xfns.c (x_char_width, x_char_height): Remove. * w32fns.c (x_char_width, x_char_height): Likewise. * nsfns.m (x_char_width, x_char_height): Likewise. * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for all window frames. (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT. * keyboard.c (command_loop_1): Remove prototype. (command_loop_2, top_level_1): Add static to match prototype. 2012-12-06 Paul Eggert Fix a recently-introduced delete-process race condition. * callproc.c, process.h (record_kill_process): New function, containing part of the old call_process_kill. (call_process_kill): Use it. This does not change call_process_kill's behavior. * process.c (Fdelete_process): Use record_kill_process to fix a race condition that could cause Emacs to lose track of a child. 2012-12-06 Dmitry Antipov Avoid code duplication between prev_frame and next_frame. * frame.c (candidate_frame): New function. Add comment. (prev_frame, next_frame): Use it. Adjust comment. 2012-12-06 Eli Zaretskii * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp fails, signal an error instead of continuing with an empty string. (Bug#13079) Encode expanded temp file pattern before passing it to mkstemp or mktemp. * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]: Encode the file name before passing it to dostounix_filename, in case it will downcase it (under w32-downcase-file-names). (Bug#12933) 2012-12-05 Paul Eggert Minor call-process cleanups. * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS at the same time as other platforms, to simplify analysis. No need for fd0_volatile since we have synch_process_fd. Avoid needless emacs_close; arg is always negative. 2012-12-04 Andreas Schwab * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous processes. 2012-12-04 Dmitry Antipov * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state member. Adjust users. Convert mouse_face_past_end, mouse_face_defer and mouse_face_hidden members to a bitfields. * frame.h (struct frame): Remove set-but-not-used space_width member. (FRAME_SPACE_WIDTH): Remove. * nsterm.m, w32term.c, xterm.c: Adjust users. * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so member. Adjust users. Convert term_initted, delete_in_insert_mode, costs_set, insert_mode, standout_mode, cursor_hidden and flow_control members to a bitfields. 2012-12-03 Paul Eggert Don't let call-process be a zombie factory (Bug#12980). Fixing this bug required some cleanup of the signal-handling code. As a side effect, this change also fixes a longstanding rare race condition whereby Emacs could mistakenly kill unrelated processes, and it fixes a bug where a second C-g does not kill a recalcitrant synchronous process in GNU/Linux and similar platforms. The patch should also fix the last vestiges of Bug#9488, a bug which has mostly been fixed on the trunk by other changes. * callproc.c, process.h (synch_process_alive, synch_process_death) (synch_process_termsig, sync_process_retcode): Remove. All uses removed, to simplify analysis and so that less consing is done inside critical sections. * callproc.c (call_process_exited): Remove. All uses replaced with !synch_process_pid. * callproc.c (synch_process_pid, synch_process_fd): New static vars. These take the role of what used to be in unwind-protect arg. All uses changed. (block_child_signal, unblock_child_signal): New functions, to avoid races that could kill innocent-victim processes. (call_process_kill, call_process_cleanup, Fcall_process): Use them. (call_process_kill): Record killed processes as deleted, so that zombies do not clutter up the system. Do this inside a critical section, to avoid a race that would allow the clutter. (call_process_cleanup): Fix code so that the second C-g works again on common platforms such as GNU/Linux. (Fcall_process): Create the child process in a critical section, to fix a race condition. If creating an asynchronous process, record it as deleted so that zombies do not clutter up the system. Do unwind-protect for WINDOWSNT too, as that's simpler in the light of these changes. Omit unnecessary call to emacs_close before failure, as the unwind-protect code does that. * callproc.c (call_process_cleanup): * w32proc.c (waitpid): Simplify now that synch_process_alive is gone. * process.c (record_deleted_pid): New function, containing code refactored out of Fdelete_process. (Fdelete_process): Use it. (process_status_retrieved): Remove. All callers changed to use child_status_change. (record_child_status_change): Remove, folding its contents into ... (handle_child_signal): ... this signal handler. Now, this function is purely a handler for SIGCHLD, and is not called after a synchronous waitpid returns; the synchronous code is moved to wait_for_termination. There is no need to worry about reaping more than one child now. * sysdep.c (get_child_status, child_status_changed): New functions. (wait_for_termination): Now takes int * status and bool interruptible arguments, too. Do not record child status change; that's now the caller's responsibility. All callers changed. Reimplement in terms of get_child_status. (wait_for_termination_1, interruptible_wait_for_termination): Remove. All callers changed to use wait_for_termination. * syswait.h: Include , for bool. (record_child_status_change, interruptible_wait_for_termination): Remove decls. (record_deleted_pid, child_status_changed): New decls. (wait_for_termination): Adjust to API changes noted above. * bytecode.c, lisp.h (Qbytecode): Remove. No longer needed after 2012-11-20 interactive-p changes. 2012-12-03 Eli Zaretskii * xdisp.c (redisplay_window): If the cursor is visible, but inside the scroll margin, move point outside the margin. (Bug#13055) 2012-12-03 Jan Djärv * gtkutil.c (my_log_handler): New function. (xg_set_geometry): Set log handler to my_log_handler (Bug#11177). 2012-12-03 Dmitry Antipov * lisp.h (modify_region): Rename to... (modify_region_1): ...new prototype. * textprop.c (modify_region): Now static. Adjust users. * insdel.c (modify_region): Rename to... (modify_region_1): ...new function to work with current buffer. Adjust comment and users. Use true and false for booleans. 2012-12-03 Dmitry Antipov * alloc.c (free_save_value): New function. (safe_alloca_unwind): Use it. * lisp.h (free_save_value): New prototype. * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value. Add comment. (save_excursion_restore): Adjust to match saved data structure. Use free_save_value to offload some work from GC. Drop obsolete #if 0 code. 2012-12-03 Chong Yidong * fileio.c (Vauto_save_list_file_name): Doc fix. 2012-12-03 Fabrice Popineau * w32fns.c: Remove prototype of atof.

(file_dialog_callback): Make it UINT_PTR. * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility with 64-bit builds. * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED) (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already defined. 2012-12-03 Glenn Morris * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding. 2012-12-02 Paul Eggert Fix xpalloc confusion after memory is exhausted. * alloc.c (xpalloc): Comment fix. * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory and signals an error, do not clear charset_table_size, as charset_table is still valid. * doprnt.c (evxprintf): Clear *BUF after freeing it. Use execve to avoid need to munge environ (Bug#13054). * callproc.c (Fcall_process): * process.c (create_process): Don't save and restore environ; no longer needed. * callproc.c (child_setup): Use execve, not execvp, to preserve environ. 2012-12-01 Paul Eggert * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500). 2012-12-01 YAMAMOTO Mitsuharu * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief display for sliced images (Bug#10500). * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise. 2012-11-30 Juanma Barranquero * doc.c (Fdocumentation): Re-add handling of function-documentation, accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034). 2012-11-29 Dmitry Antipov * xdisp.c (window_outdated): Remove eassert since it hits some suspicious corner cases (see Bug#13007 and Bug#13012).

(redisplay_internal): Move comment about buffer_shared... (buffer_shared_and_changed): ...near to its real use. 2012-11-29 Paul Eggert * callproc.c (Fcall_process): Don't misreport vfork failure. 2012-11-28 Paul Eggert * callproc.c (Fcall_process): Fix vfork portability problems. Do not assume that fd[0], count, filefd, and save_environ survive vfork. Fix bug whereby wrong errno value could be reported for pipe failure. Some minor cleanups, too, as follows. Move buf and bufsize to the context where they're needed. Change new_argv to be of type char **, as this is more convenient and avoids casts. (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX): Now local constants, not macros. 2012-11-18 Kenichi Handa * font.c (font_unparse_xlfd): Fix previous change. Keep "const" for the variable "f". 2012-11-13 Kenichi Handa * font.c (font_unparse_xlfd): Exclude special characters from the generating XLFD name. 2012-11-27 Paul Eggert Assume POSIX 1003.1-1988 or later for grp.h, pwd.h. * dired.c (stat_uname, stat_gname): * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.

(Bug#11964) * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse highlighting on the frame was cleared. Prevents assertion violations when repeatedly clicking on the "Top" link of the "bread-crumbs" in Info buffers. 2012-11-25 Paul Eggert * sysdep.c (sys_subshell): Don't assume pid_t fits in int. 2012-11-24 Ken Brown * keyboard.c (HAVE_MOUSE): * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE were always defined. 2012-11-24 Eli Zaretskii * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not between bpos_covered and bpos_max. This fixes cursor display when several display strings follow each other. * .gdbinit (pgx): If the glyph's object is a string, display the pointer to string data, rather than the value of the string object itself (which barfs under CHECK_LISP_OBJECT_TYPE). * indent.c (Fvertical_motion): If the starting position is covered by a display string, return to one position before that, to avoid overshooting it inside move_it_to. (Bug#12930) 2012-11-23 Dmitry Antipov * frame.h (struct frame): Remove display_preempted member since all users are dead long ago. * nsterm.h (struct x_output): Use the only dummy member. * w32menu.c (pending_menu_activation): Remove since not really used. (set_frame_menubar): Adjust user. * w32term.h (struct x_output): Drop outdated #if 0 code. (struct w32_output): Use bitfields for explicit_parent, asked_for_visible and menubar_active members. Drop unused pending_menu_activation member. * xterm.h (struct x_output): Drop outdated #if 0 code. Use bitfields for explicit_parent, asked_for_visible, has_been_visible and net_wm_state_hidden_seen members. 2012-11-23 Eli Zaretskii * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead of a literal "/". (Bug#12955) (gl-stamp): Invoke fc.exe directly, not through cmd. 2012-11-23 Paul Eggert Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958). * dired.c: Assume HAVE_DIRENT_H. (NAMLEN): Remove, replacing with ... (dirent_namelen): New function. All uses changed. Use the GNU macro _D_EXACT_NAMELEN if available, as it's faster than strlen. (DIRENTRY): Remove, replacing all uses with 'struct dirent'. (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero. * makefile.w32-in (DIR_H): Remove. All uses replaced with $(NT_INC)/dirent.h. ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h. * ndir.h: Rename to ../nt/inc/dirent.h. * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove. Do not include ; no longer needed. * w32.c: Include rather than "ndir.h". 2012-11-23 Chong Yidong * xftfont.c (xftfont_open): Remove duplicate assignment. 2012-11-22 Dmitry Antipov * alloc.c (Fgarbage_collect): Unblock input after clearing gc_in_progress to avoid note_mouse_highlight glitch with GC. * frame.h (FRAME_MOUSE_UPDATE): New macro. * msdos.c (IT_frame_up_to_date): Use it here... * w32term.c (w32_frame_up_to_date): ...here... * xterm.c (XTframe_up_to_date): ...and here... * nsterm.m (ns_frame_up_to_date): ...but not here. * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member. Adjust users. * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight): Do not check whether GC is in progress. 2012-11-22 Dmitry Antipov * xdisp.c (window_buffer_changed): New function. (update_menu_bar, update_tool_bar): Use it to simplify large 'if' statements. (redisplay_internal): Generalize commonly used 'tail' and 'frame' local variables. 2012-11-22 Eli Zaretskii * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts with Windows system header. 2012-11-21 Paul Eggert Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945). * alloc.c: Assume unistd.h exists. * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd. * sysdep.c (get_current_dir_name): Assume getcwd exists. (getwd) [USG]: Remove; no longer needed. (sys_subshell) [DOS_NT]: Use getcwd, not getwd. * w32.c (getcwd): Rename from getwd, and switch to getcwd's API. * w32.h (getcwd): Remove decl. 2012-11-21 Stefan Monnier * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind. Make it set selected_window as well. (update_tool_bar): Use it. 2012-11-21 Ken Brown * emacs.c (main): Set the G_SLICE environment variable for all Cygwin builds, not just GTK builds. See https://lists.gnu.org/r/emacs-devel/2012-11/msg00368.html. 2012-11-21 Eli Zaretskii * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED) (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]: Define for the MSVC compiler. * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon. * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory) (Fexpand_file_name) [DOS_NT]: Pass encoded file name to dostounix_filename. Prevents crashes down the road, because dostounix_filename assumes it gets a unibyte string. Reported by Michel de Ruiter , see https://lists.gnu.org/r/help-emacs-windows/2012-11/msg00017.html 2012-11-20 Stefan Monnier Conflate Qnil and Qunbound for `symbol-function'. * alloc.c (Fmake_symbol): Initialize `function' to Qnil. * lread.c (init_obarray): Set `function' fields to Qnil. * eval.c (Fcommandp): Ignore Qunbound. (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand): * data.c (Ffset, Ffboundp, indirect_function, Findirect_function): Test NILP rather than Qunbound. (Ffmakunbound): Set to Qnil. (Fsymbol_function): Never signal an error. (Finteractive_form): Ignore Qunbound. 2012-11-20 Paul Eggert * eval.c (interactive_p): Remove no-longer-used decl. 2012-11-20 Dmitry Antipov * xdisp.c (buffer_shared): Adjust comment. (buffer_shared_and_changed): New function. (prepare_menu_bars, redisplay_internal): Use it to decide whether all windows or frames should be updated. (window_outdated): New function. (text_outside_line_unchanged_p, redisplay_window): Use it. (redisplay_internal): Likewise. Fix indentation. 2012-11-20 Stefan Monnier * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove. (syms_of_eval): Remove corresponding defsubr. * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function. 2012-11-19 Daniel Colascione * w32fns.c (Fx_file_dialog): (Fx_file_dialog): Accommodate rename of cygwin_convert_path* to cygwin_convert_file_name*. * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32): Rename cygwin_convert_path* to cygwin_convert_file_name*. 2012-11-18 Paul Eggert * nsterm.m (ns_select): Send SIGIO only to self, not to process group. 2012-11-18 Eli Zaretskii * w32select.c: Include w32common.h before w32term.h, so that windows.h gets included before w32term.h uses some of its features, see below. * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New typedefs. (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New prototypes. (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878) 2012-11-18 Jan Djärv * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834). (ns_select): Return at once if events are held (Bug#12834). 2012-11-18 enami tsugutomo * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64. Needed following 2012-10-20 change. (Bug#12902) 2012-11-18 Juanma Barranquero * w32proc.c (waitpid): Remove unused label get_result. 2012-11-17 Juanma Barranquero * makefile.w32-in (SYSWAIT_H): New macro. ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O)) ($(BLD)/sysdep.$(O)): Update dependencies. 2012-11-17 Paul Eggert Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881). * callproc.c (relocate_fd): Assume F_DUPFD. * emacs.c, term.c (O_RDWR): Remove. * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than O_NDELAY, since O_NONBLOCK is the standard name for this flag. * nsterm.m: Assume exists. * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process) (create_pty, Fmake_network_process, server_accept_connection) (wait_reading_process_output, init_process_emacs): Assume O_NONBLOCK. (wait_reading_process_output): Put in a special case for WINDOWSNT to mimic the older behavior where it had O_NDELAY but not O_NONBLOCK. It's not clear this is needed, but it's a more-conservative change. (create_process): Assume FD_CLOEXEC. (create_process, create_pty): Assume O_NOCTTY. * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL. (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY. Omit if not DOS_NT, since F_GETFL is not defined there. (serial_open): Assume O_NONBLOCK and O_NOCTTY. * term.c: Include , for flags like O_NOCTTY. (O_NOCTTY): Remove. (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that lack it, since gnulib guarantees this. * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY. 2012-11-17 Eli Zaretskii * w32.c (faccessat): Pretend that directories have the execute bit set. Emacs expects that, e.g., in files.el:cd-absolute. * w32proc.c (create_child): Don't clip the PID of the child process to fit into an Emacs integer, as this is no longer a restriction. (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by reaping only the process specified by PID argument, if that is positive. Use PID instead of dead_child to know which process to reap. Wait for the child to die only if WNOHANG is not in OPTIONS. (sys_select): Don't set dead_child. * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion, as it is no longer needed. * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions, no longer needed. (record_child_status_change): Remove the setting of record_at_most_one_child for the !WNOHANG case. 2012-11-17 Paul Eggert Fix problems in ns port found by static checking. * nsterm.m: Include , for pthread_mutex_lock etc. (hold_event, setPosition:portion:whole:): Send SIGIO only to self, not to process group. (ns_select): Use emacs_write, not write, as that's more robust in the presence of signals. (fd_handler:): Check for read errors. 2012-11-16 Glenn Morris * editfns.c (Fmessage): Mention message-log-max. (Bug#12849) 2012-11-16 Stefan Monnier * eval.c (Finteractive_p): Revert lexbind-merge mishap. 2012-11-16 Eli Zaretskii * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread use the same value of thread handle. (start_timer_thread): If the timer thread exited (due to error), clean up by closing the two handles it used. Duplicate the caller thread's handle here, so it gets duplicated only once, when launching the timer thread. Set priority of the timer thread, not the caller thread. (getitimer): Don't duplicate the caller thread's handle here. (Bug#12832) 2012-11-16 Jan Djärv * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is called (Bug#12834). 2012-11-16 Paul Eggert Remove no-longer-used pty_max_bytes variable. * process.c (pty_max_bytes): Remove; unused. (send_process): Do not set it. 2012-11-15 Juanma Barranquero * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)): Update dependencies. 2012-11-15 Paul Eggert * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'. This follows up on the 2012-09-29 patch that removed indirection for the 'function' field. Reported by Sergey Vinokurov in . 2012-11-14 Eli Zaretskii * w32.c (faccessat): Rename from sys_faccessat. (No need to use a different name, as the MS runtime does not have such a function, and probably never will.) All callers changed. Ignore DIRFD value if PATH is an absolute file name, to match Posix spec better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve symlinks. 2012-11-14 Dmitry Antipov * xdisp.c (echo_area_display, redisplay_internal): Omit redundant check whether frame_garbaged is set. 2012-11-14 Paul Eggert Use faccessat, not access, when checking file permissions (Bug#12632). This fixes a bug that has been present in Emacs since its creation. It was reported by Chris Torek in 1983 even before GNU Emacs existed, which must set some sort of record. (Torek's bug report was against a predecessor of GNU Emacs, but GNU Emacs happened to have the same common flaw.) See Torek's Usenet posting "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858 Posted: Fri Apr 8 14:18:56 1983. * Makefile.in (LIB_EACCESS): New macro. (LIBES): Use it. * callproc.c (init_callproc): * charset.c (init_charset): * fileio.c (check_existing, check_executable, check_writable) (Ffile_readable_p): * lread.c (openp, load_path_check): * process.c (allocate_pty): * xrdb.c (file_p): Use effective UID when checking permissions, not real UID. * callproc.c (init_callproc): * charset.c (init_charset): * lread.c (load_path_check, init_lread): Test whether directories are accessible, not merely whether they exist. * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro. * fileio.c (check_existing, check_executable, check_writable) (Ffile_readable_p): Use symbolic names instead of integers for the flags, as they're portable now. (check_writable): New arg AMODE. All uses changed. Set errno on failure. (Ffile_readable_p): Use faccessat, not stat + open + close. (Ffile_writable_p): No need to call check_existing + check_writable. Just call check_writable and then look at errno. This saves a syscall. dir should never be nil; replace an unnecessary runtime check with an eassert. When checking the parent directory of a nonexistent file, check that the directory is searchable as well as writable, as we can't create files in unsearchable directories. (file_directory_p): New function, which uses 'stat' on most platforms but faccessat with D_OK (for efficiency) if WINDOWSNT. (Ffile_directory_p, Fset_file_times): Use it. (file_accessible_directory_p): New function, which uses a single syscall for efficiency. (Ffile_accessible_directory_p): Use it. * xrdb.c (file_p): Use file_directory_p. * lisp.h (file_directory_p, file_accessible_directory_p): New decls. * lread.c (openp): When opening a file, use fstat rather than stat, as that avoids a permissions race. When not opening a file, use file_directory_p rather than stat. (dir_warning): First arg is now a usage string, not a format. Use errno. All uses changed. * nsterm.m (ns_term_init): Remove unnecessary call to file-readable that merely introduced a race. * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK' changed to '#if O_NONBLOCK', to accommodate gnulib O_* style, and similarly for the other O_* flags. * w32.c (sys_faccessat): Rename from sys_access and switch to faccessat's API. All uses changed. * xrdb.c: Do not include ; no longer needed. (magic_db): Rename from magic_file_p. (magic_db, search_magic_path): Return an XrmDatabase rather than a char *, so that we don't have to test for file existence separately from opening the file for reading. This removes a race fixes a permission-checking problem, and simplifies the code. All uses changed. (file_p): Remove; no longer needed. 2012-11-13 Dmitry Antipov Omit glyphs initialization at startup. * dispnew.c (glyphs_initialized_initially_p): Remove. (adjust_frame_glyphs_initially): Likewise. Adjust users. (Fredraw_frame): Move actual code from here... (redraw_frame): ...to here. Add eassert. Adjust comment. (Fredraw_display): Use redraw_frame. * xdisp.c (clear_garbaged_frames): Likewise. 2012-11-13 Eli Zaretskii * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument passed to pint2str and pint2hrstr to be at most the size of the frame's decode_mode_spec_buffer. This avoids crashes with very large values of FIELD_WIDTH argument to decode_mode_spec. (Bug#12867) 2012-11-13 Paul Eggert Fix a race with verify-visited-file-modtime (Bug#12863). Since at least 1991 Emacs has ignored an mtime difference of no more than one second, but my guess is that this was to work around file system bugs that were fixed long ago. Since the race is causing problems now, let's remove that code. * fileio.c (Fverify_visited_file_modtime): Do not accept a file whose time stamp is off by no more than a second. Insist that the file time stamps match exactly. 2012-11-12 Dmitry Antipov * frame.h (struct frame): Convert external_tool_bar member to 1-bit unsigned bitfield. * termhooks.h (struct terminal): Remove mouse_moved member since all users are long dead. Adjust comment on mouse_position_hook. 2012-11-12 Dmitry Antipov Simplify by using FOR_EACH_FRAME here and there. * frame.c (next_frame, prev_frame, other_visible_frames) (delete_frame, visible-frame-list): Use FOR_EACH_FRAME. * w32term.c (x_window_to_scroll_bar): Likewise. * window.c (window_list): Likewise. * xdisp.c (x_consider_frame_title): Likewise. * xfaces.c (Fdisplay_supports_face_attributes_p): Likewise. * xfns.c (x_window_to_frame, x_any_window_to_frame) (x_menubar_window_to_frame, x_top_window_to_frame): Likewise. * xmenu.c (menubar_id_to_frame): Likewise. * xselect.c (frame_for_x_selection): Likewise. * xterm.c (x_frame_of_widget, x_window_to_scroll_bar) (x_window_to_menu_bar): Likewise. * w32fns.c (x_window_to_frame): Likewise. Adjust comment. 2012-11-12 Paul Eggert * data.c (Qdefalias_fset_function): Now static. Another tweak to vectorlike_header change. * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST): Remove, and replace all uses with ... (next_in_free_list, set_next_in_free_list): New functions, which respect C's aliasing rules better. 2012-11-11 Paul Eggert * window.c (list4i): Rename from 'quad'. All uses changed. Needed because defines 'quad' on Solaris 10. 2012-11-11 Juanma Barranquero * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence warning about mixing declarations and code in ISO C90. 2012-11-10 Martin Rudalics * window.c (Fsplit_window_internal): Set combination limit of new parent window to t iff Vwindow_combination_limit is t; fixing a regression introduced with the change from 2012-09-22. (Fset_window_combination_limit): Fix doc-string. 2012-11-10 Eli Zaretskii * xdisp.c (try_scrolling): Fix correction of aggressive-scroll amount when the scroll margins are too large. When scrolling backwards in the buffer, give up if cannot reach point or the scroll margin within a reasonable number of screen lines. Fixes point position in window under scroll-up/down-aggressively when point is positioned many lines beyond the window top/bottom. (Bug#12811) * ralloc.c (relinquish): If real_morecore fails to return memory to the system, don't crash; instead, leave the last heap unchanged and return. (Bug#12774) 2012-11-09 Stefan Monnier * lisp.h (AUTOLOADP): New macro. * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead. * data.c (Ffset): Remove special ad-advice-info handling. (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function. (Fsubr_arity): CSE. (Finteractive_form): Simplify. (Fquo): Don't insist on having at least 2 arguments.

(SCROLL_BAR_VEC_SIZE): Remove. * w32term.c (x_scroll_bar_create): Use VECSIZE. 2012-11-09 Dmitry Antipov Tweak last vectorlike_header change. * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent vectorlike object on the free list. This is introduced to avoid some (but not all) pointer casting and aliasing problems, see https://lists.gnu.org/r/emacs-devel/2012-11/msg00105.html. * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike objects. (xvectype, xvecsize): Use them to examine Lisp_Object values. 2012-11-09 Jan Djärv * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has been removed, so remove them here also. 2012-11-09 Stefan Monnier * doc.c (Fdocumentation): Handle new property dynamic-docstring-function to replace the old ad-advice-info. 2012-11-09 Paul Eggert * fns.c (Qeql, hashtest_eq): Now static. 2012-11-08 Stefan Monnier * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int. * fns.c (hashfn_eq, hashfn_eql, sxhash): * profiler.c (hashfn_profiler): Don't use XUINT on non-integers. * buffer.c (compare_overlays): Use XLI rather than XHASH. 2012-11-08 Paul Eggert Use same hash function for hashfn_profiler as for hash_string etc. * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine. * lisp.h (sxhash_combine): New inline function, with the contents of the old SXHASH_COMBINE. * profiler.c (hashfn_profiler): Use it, instead of having a special hash function containing a comparison that always yields 1. 2012-11-08 Stefan Monnier * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic) (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed) (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded): Remove unused vars. 2012-11-08 Jan Djärv * image.c (xpm_make_color_table_h): Fix compiler error because make_hash_table changed. 2012-11-08 Thomas Kappler (tiny change) * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541). 2012-11-08 Stefan Monnier Use ad-hoc comparison function for the profiler's hash-tables. * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.

(allocate_vectorlike): Likewise. (allocate_pseudovector): Change type of 3rd arg to enum pvec_type. Add easserts. Adjust XSETPVECTYPESIZE usage. (allocate_buffer): Use BUFFER_PVEC_INIT. (live_vector_p): Adjust to match large vector. * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT. * buffer.h (struct buffer): Add next member. (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT): New macros. (FOR_EACH_BUFFER): Adjust to match struct buffer change. * fns.c (internal_equal): Adjust to match enum pvec_type change. (copy_hash_table): Adjust to match vector header change. * lread.c (defsubr): Use XSETPVECTYPE. * .gdbinit (xpr, xbacktrace): Adjust to match vector header change. (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors. (xvecsize): New command. 2012-11-08 Dmitry Antipov * keyboard.c (event_to_kboard): Do not dereference frame_or_window field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT events (Bug#12814). * xterm.h (struct selection_input_event): Adjust comment. 2012-11-07 Eli Zaretskii * w32fns.c (modifier_set): Don't report modifiers from toggle key, such as Scroll Lock, if the respective keys are treated as function keys, not as modifiers. This avoids destroying non-ASCII keyboard input when Scroll Lock is toggled ON. (Bug#12806) 2012-11-07 Dmitry Antipov * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring. 2012-11-06 Paul Eggert Restore some duplicate definitions (Bug#12814). This undoes part of the 2012-11-03 changes. Some people build with plain -g rather than with -g3, and they need the duplicate definitions for .gdbinit to work; see . * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Define as macros, as well as enums or constants. 2012-11-06 Jan Djärv * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask to keypad keys (Bug#12816). 2012-11-06 Paul Eggert Minor adjustments of recently-changed frame functions. * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already known to be a frame (we're in the FRAMEP branch). * lisp.h (Qframep): Remove decl. frame.h declares this. * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t, since they're meant for Lisp fixnum values. 2012-11-06 Dmitry Antipov * window.c (Fwindow_combination_limit): Revert to the only required argument and adjust docstring as suggested in https://lists.gnu.org/r/emacs-diffs/2012-11/msg01082.html by Martin Rudalics . 2012-11-06 Dmitry Antipov Widely used frame validity and checking functions. * frame.h (decode_live_frame, decode_any_frame): Add prototypes. * frame.c (decode_live_frame, decode_any_frame): New functions. (delete_frame, Fredirect_frame_focus, Fframe_parameters) (Fframe_parameter, Fframe_char_height, Fframe_char_width) (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width) (Fframe_pointer_visible_p): Use decode_any_frame. (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame) (Fraise_frame, Flower_frame, Fmodify_frame_parameters) (Fset_frame_height, Fset_frame_width): Use decode_live_frame. (Fframe_focus): Likewise. Allow zero number of arguments. Adjust docstring. (frame_buffer_list, frame_buffer_predicate): Remove. * lisp.h (frame_buffer_predicate): Remove prototype. * buffer.c (Fother_buffer): Use decode_any_frame. * xdisp.c (Ftool_bar_lines_needed): Likewise. * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise. * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font) (Fclose_font, Ffont_info): Use decode_live_frame. * fontset.c (check_fontset_name): Likewise. * terminal.c (Fframe_terminal): Likewise. * w32fns.c (check_x_frame): Likewise. * window.c (Fminibuffer_window, Fwindow_at) (Fcurrent_window_configuration): Likewise. (Frun_window_configuration_change_hook, Fwindow_resize_apply): Likewise. Allow zero number of arguments. Adjust docstring. * dispnew.c (Fredraw_frame): Likewise. * xfaces.c (frame_or_selected_frame): Remove. (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font) (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p) (Fframe_face_alist): Use decode_live_frame. * xfns.c (check_x_frame): Likewise. 2012-11-06 Dmitry Antipov * window.c (quad): New function. (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges) (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges) (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p) (Fwindow_line_height): Use it. (Fwindow_fringes): Use list3. (Fwindow_scroll_bars): Use list4. (Fwindow_frame, Fwindow_top_child, Fwindow_left_child) (Fwindow_combination_limit): Allow zero number of arguments. 2012-11-05 Eli Zaretskii * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h. * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin. (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use file descriptor 2 for standard error. (Bug#12805) 2012-11-05 Chong Yidong * process.c (wait_reading_process_output): Revert previous change. 2012-11-05 Paul Eggert Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800). This removes code that has been obsolete since around 1990. * callproc.c (Fcall_process): * emacs.c (main): * process.c (create_process): * term.c (dissociate_if_controlling_tty): Assume setsid exists. * callproc.c (child_setup): Assume setpgid exists and behaves as per POSIX.1-1988 or later. * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove. * emacs.c (shut_down_emacs): * sysdep.c (sys_suspend, init_foreground_group): Assume getpgrp behaves as per POSIX.1-1998 or later. * msdos.c (setpgrp): Remove. (tcgetpgrp, setpgid, setsid): New functions. * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp. * term.c (no_controlling_tty): Remove; unused. * w32proc.c (setpgrp): Remove. (setsid, tcgetpgrp): New functions. Simplify by assuming __fpending. * dispnew.c: Include , not . (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT. Do not assume that __fpending's result fits in int. 2012-11-04 Paul Eggert Remove EMACS_OUTQSIZE+sleep hack. * dispnew.c (update_frame_1): Remove hack for terminals slower than 2400 bps, which throttled Emacs by having it sleep. This code hasn't worked since at least 2007, when the multi-tty stuff was added, and anyway those old terminals are long dead. * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even without the dispnew.c change, as dispnew.c doesn't include systty.h. Fix data-loss with --version (Bug#9574). * emacs.c (close_output_streams): Use strerror, not emacs_strerror, as we can't assume that emacs_strerror is initialized, and strerror is good enough here. (main): Invoke atexit earlier, to catch earlier instances of sending data to stdout and exiting, e.g., "emacs --version >/dev/full". 2012-11-04 Michael Marchionna * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680). (keyDown): Remap keypad keys to X11 virtual key codes. 2012-11-03 Paul Eggert Fix data-loss with --batch (Bug#9574). * emacs.c: Include . (close_output_streams): New function. (main): Pass it to atexit, so that Emacs closes stdout and stderr and handles errors appropriately. (Fkill_emacs): Don't worry about flushing, as close_output_stream does that now. Fix a race condition that causes Emacs to mess up glib (Bug#8855). The symptom is a diagnostic "GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned." The diagnostic is partly wrong, as the SIGCHLD action is not set to SIG_IGN. The real bug is a race condition between Emacs and glib: Emacs does a waitpid (-1, ...) and reaps glib's subprocess by mistake, so that glib can't find it. Work around the bug by invoking waitpid only on subprocesses that Emacs itself creates. * process.c (create_process, record_child_status_change): Don't use special value -1 in pid field, as the caller now must know the pid rather than having the callee infer it. The inference was sometimes incorrect anyway, due to another race. (create_process): Set new 'alive' member if child is created. (process_status_retrieved): New function. (record_child_status_change): Use it. Accept negative 1st argument, which means to wait for the processes that Emacs already knows about. Move special-case code for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of processes that have already been waited for, by testing and clearing new 'alive' member. (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change now does this internally. (handle_child_signal): Let record_child_status_change do all the work, since we do not want to reap all exited child processes, only the child processes that Emacs itself created. * process.h (Lisp_Process): New boolean member 'alive'. Omit duplicate definitions no longer needed with gcc -g3. * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG) (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM): Define only as macros. There's no longer any need to also define these symbols as enums or as constants, since we now assume gcc -g3 when debugging. 2012-11-03 Eli Zaretskii * lisp.mk: Adjust comments to the fact that term/internal is now loaded from loadup.el. * msdos.c (msdos_abort): Rename from emacs_abort, and make static. (msdos_fatal_signal): New function. (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to its argument list. * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline" for GCC versions before 4. (emacs_raise): Define to call msdos_fatal_signal. * xdisp.c (init_from_display_pos): Fix initialization of the bidi iterator when starting in the middle of a display or overlay string. (Bug#12745) 2012-11-03 Chong Yidong * process.c (wait_reading_process_output): Clean up the last change. 2012-11-03 Jim Paris (tiny change) * process.c (wait_reading_process_output): Avoid a race condition with SIGIO delivery (Bug#11536). 2012-11-03 Chong Yidong * buffer.c (cursor_type): Untabify docstring. 2012-11-03 Dmitry Antipov * frame.h (struct frame): Drop can_have_scroll_bars member which is meaningless for a long time. Adjust comments. (FRAME_CAN_HAVE_SCROLL_BARS): Remove. * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users. 2012-11-03 Dmitry Antipov * window.c (decode_next_window_args): Update window arg after calling decode_live_window and so fix crash reported at https://lists.gnu.org/r/emacs-devel/2012-11/msg00035.html by Juanma Barranquero . (Fwindow_body_width, Fwindow_body_height): Simplify a bit. * font.c (Ffont_at): Likewise. 2012-11-01 Jan Djärv * widget.c (resize_cb): New function. (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733). (EmacsFrameResize): Check if all is up to date before changing frame size. 2012-11-02 Eli Zaretskii Implement backtrace output for fatal errors on MS-Windows. * w32fns.c (CaptureStackBackTrace_proc): New typedef. (BACKTRACE_LIMIT_MAX): New macro. (w32_backtrace): New function. (emacs_abort): Use w32_backtrace when the user chooses not to attach a debugger. Update the text of the abort dialog. 2012-11-02 Dmitry Antipov Window-related stuff cleanup here and there. * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p): Use decode_any_window. * fringe.c (Ffringe_bitmaps_at_pos): Likewise. * xdisp.c (Fformat_mode_line): Likewise. * font.c (Ffont_at): Use decode_live_window. * indent.c (Fcompute_motion, Fvertical_motion): Likewise. * window.c (decode_next_window_args): Likewise. (decode_any_window): Remove static. * window.h (decode_any_window): Add prototype. * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here... * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P, respectively. 2012-11-02 Dmitry Antipov Remove pad from struct input_event. * termhooks.h (struct input_event): Remove padding field. Adjust comment. * keyboard.c (event_to_kboard): Simplify because frame_or_window member is never cons for a long time. Adjust comment. (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment. * xterm.c (handle_one_xevent): Do not initialize frame_or_window field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT. 2012-11-01 Eli Zaretskii * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776) 2012-10-31 Paul Eggert Fix crash when using Emacs as commit editor for git (Bug#12697). * callproc.c (setpgrp): Remove macro, as we now use setpgid and it is configured in conf_post.h. (Fcall_process): Don't invoke both setsid and setpgid; the former is enough, if it exists. * callproc.c (Fcall_process, child_setup): * process.c (create_process): Use setpgid. * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes for the real thing. * dispnew.c (init_display): Initialize the foreground group if we are running a tty display. * emacs.c (main): Do not worry about setpgrp; init_display does it now. * lisp.h (init_foreground_group): New decl. * sysdep.c (inherited_pgroup): New static var. (init_foreground_group, tcsetpgrp_without_stopping) (narrow_foreground_group, widen_foreground_group): New functions. (init_sys_modes): Narrow foreground group. (reset_sys_modes): Widen foreground group. 2012-10-31 Michael Albinus * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE. 2012-10-31 Martin Rudalics * minibuf.c (read_minibuf): Restore current buffer since choose_minibuf_frame calling Fset_frame_selected_window may change it (Bug#12766). 2012-10-30 Jan Djärv * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733). 2012-10-30 Kenichi Handa * font.c (Ffont_at): If WINDOW is specified and it is not displaying the current buffer, signal an error. 2012-10-29 Daniel Colascione * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In preparation for fixing bug#12739, move these functions from here... * coding.h, coding.c: ... to here, and compile them only when WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper lets us write cygw32-agnostic code for the HAVE_NTGUI case. 2012-10-28 Eli Zaretskii * w32proc.c (TIMER_TICKS_PER_SEC): New macro. (timer_loop, getitimer, setitimer): Use it instead of CLOCKS_PER_SEC, which is no longer pertinent, since we don't use 'clock'. (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a literal 10000. 2012-10-28 Jan Djärv * nsterm.m (NO_APPDEFINED_DATA): New define. (last_appdefined_event_data): New variable (last_appdefined_event): Remove. (ns_select): Initialize t from last_appdefined_event_data instead of [last_appdefined_event data1]. (sendEvent:): Save [theEvent data1] to last_appdefined_event_data, remove last_appdefined_event (Bug#12698). 2012-10-28 Stefan Monnier * frame.c (x_set_font): Catch internal error. 2012-10-27 Eli Zaretskii Avoid overflow in w32 implementation of interval timers. When possible, for ITIMER_PROF count only times the main thread actually executes. * w32proc.c : 'expire' and 'reload' are now 'volatile ULONGLONG' types. All the other data which was previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'. (GetThreadTimes_Proc): New typedef. (w32_get_timer_time): New function, returns a suitable time value for the timer. (timer_loop): Enter critical section when accessing ULONGLONG values of the itimer_data struct, as these accesses are no longer atomic. Call 'w32_get_timer_time' instead of 'clock'. Remove unused variable. (init_timers): Initialize s_pfn_Get_Thread_Times. (start_timer_thread): Don't assign itimer->caller_thread here. (getitimer): Assign itimer->caller_thread here. (setitimer): Always call getitimer to get the value of ticks_now. (sys_spawnve): Avoid compiler warning about format mismatch. 2012-10-26 Eli Zaretskii * w32fns.c (w32_wnd_proc) : Don't enable tracking of mouse movement events if the menu bar is active. This avoids producing a busy "hour-glass" cursor by Windows if the mouse pointer is positioned over a tooltip shown for some menu item. 2012-10-25 Paul Eggert Don't assume process IDs fit in int. * emacs.c (shut_down_emacs) [!DOS_NT]: * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]: * term.c (dissociate_if_controlling_tty) [!DOS_NT]: Use pid_t, not int, to store process IDs, as 'int' is not wide enough on a few platforms (e.g., AIX and IRIX). 2012-10-23 Kenichi Handa The following change is to make face-font-rescale-alist work correctly for non-ASCII fonts. * font.c (font_open_entity): Don't handle Vface_font_rescale_alist. (font_open_for_lface): Handle Vface_font_rescale_alist. 2012-10-23 Chong Yidong * xfaces.c (Vfont_list_limit): Move unused variable to faces.el. 2012-10-21 Jan Djärv * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement for screen font. (nsfont_draw): Turn off LCD-smoothing (Bug#11484). * xterm.c (x_focus_changed): Check if daemonp when sending focus in event (Bug#12681). 2012-10-21 Glenn Morris * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el. 2012-10-20 Paul Eggert Port to OpenBSD 5.1. * frame.c (Fmouse_position, Fmouse_pixel_position): * xdisp.c (produce_stretch_glyph): Declare local vars only when they're needed. This is clearer and avoids a warning on OpenBSD about unused vars. * frame.h (FRAME_WINDOW_P): Always evaluate its argument. This is safer, and avoids OpenBSD warnings about unused vars. * keyboard.c (record_menu_key): Remove unnecessary decl. (poll_timer): Define only if POLL_FOR_INPUT is defined. * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined, as our definition clashes with OpenBSD's. * xfaces.c (load_face_colors, check_lface_attrs) (get_lface_attributes_no_remap, get_lface_attributes) (lface_fully_specified_p, x_supports_face_attributes_p) (tty_supports_face_attributes_p, face_fontset, realize_face) (realize_x_face, realize_tty_face): Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not merely Lisp_Object *. This is more informative and avoids a warning on OpenBSD about accessing beyond an object's size. 2012-10-20 Chong Yidong * lread.c (Fload): Doc fix (Bug#12592). 2012-10-19 Kazuhiro Ito (tiny change) * font.c (Ffont_at): Fix previous change. 2012-10-19 Eli Zaretskii * puresize.h (BASE_PURESIZE): Bump the base value to 1700000. See https://lists.gnu.org/r/emacs-devel/2012-10/msg00593.html for the reasons. * alloc.c (NSTATICS): Decrease to 0x800. 2012-10-19 Stefan Monnier * fns.c (Fnreverse): Include the problem element when signaling an error (bug#12677). 2012-10-18 Jan Djärv * nsterm.m (ns_select): Check writefds before call to FD_ISSET (Bug#12668). 2012-10-18 Daniel Colascione * alloc.c (NSTATICS): Increase from 0x650 to 0x1000 (staticpro): If we run out of staticpro slots, die with an informative error instead of just calling emacs_abort. 2012-10-18 Martin Rudalics Fix two flaws reported by Dmitry Antipov. * window.c (Ftemp_output_buffer_show): Remove. (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.

(sys_access, e_malloc, sys_select): Add prototypes. (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval. * vm-limit.c [WINDOWSNT]: Include w32heap.h. * unexw32.c: Include lisp.h and w32.h. * term.c [WINDOWSNT]: Include w32term.h. * process.c [WINDOWSNT]: Add prototype of sys_select. * fileio.c [WINDOWSNT]: Include w32.h. * dispnew.c [WINDOWSNT]: Include w32.h. * cygw32.c (Fcygwin_convert_path_to_windows) (Fcygwin_convert_path_from_windows): Use EQ to compare 2 Lisp_Object values. (Bug#12661) * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer to Lisp_Object. (Bug#12661) 2012-10-17 Kenichi Handa * xdisp.c (reseat_1): Make the information stored in it->cmp_it invalidate. 2012-10-17 Dmitry Antipov * buffer.c (Fkill_buffer): When unchaining the marker, reset its buffer pointer to NULL (Bug#12652). 2012-10-17 Dmitry Antipov Do not verify indirection counters of killed buffers (Bug#12579). * buffer.h (BUFFER_CHECK_INDIRECTION): New macro. * buffer.c (compact_buffer, set_buffer_internal_1): Use it. 2012-10-16 Dmitry Antipov * alloc.c (Fmake_byte_code): Fix typo in comment. * print.c (print_interval): Define as static to match prototype. * indent.c (disptab_matches_widthtab, recompute_width_table): Convert to eassert. 2012-10-16 Dmitry Antipov * editfns.c (get_system_name): Remove. * lisp.h (get_system_name): Remove prototype. * xrdb.c (getenv, getpwuid, getpwnam): Remove prototypes. (get_environ_db): Use Vsystem_name. Avoid call to strlen. 2012-10-15 Daniel Colascione * dbusbind.c: Add comment explaining reason for previous change. 2012-10-15 Martin Rudalics * window.c (Fwindow_end): Rewrite check whether cached position can be used (Bug#12600). (resize_frame_windows, grow_mini_window, shrink_mini_window): Set windows_or_buffers_changed. 2012-10-15 Daniel Colascione * dbusbind.c: Fix cygw32 build break when compiling with dbus enabled by undefining the symbol "interface", which the platform headers define to something incompatible. 2012-10-14 Daniel Colascione * image.c (init_tiff_functions, init_imagemagick_functions) (init_svg_functions): Fix cygw32 build break by using these functions only when WINDOWSNT _and_ HAVE_NTGUI. 2012-10-14 Jan Djärv * nsterm.m (ns_select): Count fd:s in writefs also (Bug#12422). 2012-10-13 Jan Djärv * gtkutil.c (xg_set_widget_bg): Divide by 65535 (Bug#12612). 2012-10-13 HANATAKA, Shinya (tiny change) * coding.c (detect_coding): Set coding->id before calling this->detector. 2012-10-13 Andreas Schwab * fileio.c: Formatting fixes. 2012-10-13 Paul Eggert Fix some stat-related races. * fileio.c (Fwrite_region): Avoid race condition if a file is removed or renamed by some other process immediately after Emacs writes it but before Emacs stats it. Do not assume that stat (or fstat) succeeds. * image.c (slurp_file): Resolve the file name with fopen + fstat rather than stat + fopen. (pbm_read_file) [0]: Remove unused code with stat race. * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]: Remove ineffective code with stat race. 2012-10-12 Stefan Monnier * doc.c (get_doc_string): Don't signal an error if the file is missing. 2012-10-12 Jan Djärv * nsterm.m (hold_event_q): New static variable.

(make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it instead of calling 'stat', when what's needed is to check whether a file exists. This avoids expensive system calls on MS-Windows. (Bug#12587) * w32.c (init_environment): Call 'check_existing' instead of 'stat'. * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to determine whether a file exists and is not a directory. * lisp.h (check_existing): Add prototype. 2012-10-12 Jan Djärv * nsfont.m (nsfont_open): Remove font cache, it is not GC correct. 2012-10-12 Glenn Morris * buffer.c (Fset_buffer): Doc fix. (Bug#12624) 2012-10-11 Stefan Monnier * buffer.c (Fkill_buffer): Null out the overlay list(s) as well. * eval.c (Fautoload): Remember previous autoload status in load-history. 2012-10-11 Paul Eggert lread.c, macros.c, marker.c, menu.c, minibuf.c: Use bool for booleans. * lread.c (load_each_byte, new_backquote_flag, readchar) (read_filtered_event, lisp_file_lexically_bound_p) (safe_to_load_version, Fload, complete_filename_p, openp) (build_load_history, readevalloop, read_escape, read1) (string_to_number, read_vector, read_list): * macros.c (Fstart_kbd_macro): * marker.c (CONSIDER): * menu.c (parse_single_submenu, digest_single_submenu) (find_and_return_menu_selection, Fx_popup_menu): * minibuf.c (read_minibuf_noninteractive, read_minibuf) (Ftry_completion): * nsmenu.m (ns_update_menubar, runMenuAt:forFrame:keymaps:): (ns_menu_show): * xmenu.c (set_frame_menubar, create_and_show_popup_menu) (xmenu_show, xdialog_show): Use bool for booleans. * lread.c (safe_to_load_version): Rename from safe_to_load_p, as it's not a predicate. All uses changed. Omit unnecessary buffer termination. 2012-10-11 Dmitry Antipov * editfns.c (save_excursion_save): Use nil if mark points to nowhere. (save_excursion_restore): Do not restore mark if it was not saved. 2012-10-11 Paul Eggert * marker.c (cached_modiff): EMACS_INT, not int. * w32select.c (waiting_for_input): Declare by including "keyboard.h" instead of having a wrong decl. * nsmenu.m (waiting_for_input): Remove wrong decl. 2012-10-10 Paul Eggert keyboard.c, keymap.c: Use bool for booleans. * dispnew.c (sit_for): Distinguish between 3-way display_option and boolean do_display. * keyboard.c (single_kboard, this_command_key_count_reset) (waiting_for_input, echoing, immediate_quit, input_pending) (interrupt_input, interrupts_deferred, pop_kboard) (temporarily_switch_to_single_kboard, ignore_mouse_drag_p) (command_loop_1, adjust_point_for_property) (safe_run_hooks_error, input_polling_used, read_char): (help_char_p, readable_events, kbd_buffer_events_waiting) (kbd_buffer_get_event, timer_check_2, make_lispy_event) (lucid_event_type_list_p, get_input_pending): (gobble_input, menu_separator_name_p, menu_bar_item) (parse_menu_item, parse_tool_bar_item, read_char_x_menu_prompt) (read_char_minibuf_menu_prompt, access_keymap_keyremap) (keyremap_step, test_undefined, read_key_sequence) (detect_input_pending, detect_input_pending_ignore_squeezables) (detect_input_pending_run_timers, requeued_events_pending_p) (quit_throw_to_read_char, Fset_input_interrupt_mode): * keymap.c (get_keymap, keymap_parent, keymap_memberp) (access_keymap_1, access_keymap, map_keymap, get_keyelt) (Fdefine_key, Flookup_key, struct accessible_keymaps_data) (accessible_keymaps_1, Fkey_description, push_key_description): (shadow_lookup, struct where_is_internal_data) (where_is_internal, Fwhere_is_internal, where_is_internal_1) (Fdescribe_buffer_bindings, describe_map_tree, struct describe_map_elt) (describe_map, describe_vector): * menu.c (single_menu_item): * nsmenu.m (ns_update_menubar): * process.c (wait_reading_process_output): * search.c (scan_buffer, scan_newline): Use bool for boolean. * keyboard.c (timers_run, swallow_events) (detect_input_pending_run_timers): * process.c (wait_reading_process_output): Use unsigned for counter where wraparound-on-overflow is desired, since unsigned is guaranteed to have that behavior and signed is not. (read_char): Use ptrdiff_t for string length. (get_input_pending): Remove first argument, since it was always the same pointer-to-int (now pointer-to-boolean) &input_pending, and behave as if it had that value. Return new value of input_pending. All callers changed. * keyboard.h (struct kboard): Use unsigned : 1 for boolean member immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's a string length. * keymap.c (push_key_description): Omit last arg, which was always 1. All callers changed. * regex.c (immediate_quit) [emacs]: Remove duplicate decl. 2012-10-10 Juanma Barranquero * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/indent.$(O)) ($(BLD)/term.$(O)): Update dependencies. 2012-10-10 Dmitry Antipov * alloc.c (mark_object): Use meaningful PVEC_NORMAL_VECTOR. * lisp.h (enum pvec_type): Adjust comments and omit explicit initializer for PVEC_NORMAL_VECTOR. 2012-10-10 Paul Eggert Clean out old termopts cruft. * termopts.h (flow_control, meta_key): Remove unused decls. * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c: Don't include termopts.h. 2012-10-10 Dmitry Antipov * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers. 2012-10-10 Paul Eggert * commands.h (immediate_quit): Remove duplicate decl. 2012-10-09 Jan Djärv * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles caching. (nsfont_open): Remove setting of Vfonts_in_cache. (syms_of_nsfont): Remove initialization of Vfonts_in_cache. 2012-10-09 Eli Zaretskii * w32fns.c (w32_last_error): Change the return value to DWORD, to match what GetLastError returns. Explain why the function is needed. * frame.c (delete_frame): Rename local variable 'tooltip_frame' to 'is_tooltip_frame', to avoid confusion with its global namesake. 2012-10-08 Daniel Colascione * xdisp.c (start_hourglass): Call w32_note_current_window when HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32 build that caused Emacs to display the hourglass cursor forever. * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS, which is broken under remote desktop, calculate the number of colors available for a display based on the display's number of planes and number of bits per pixel per plane. (bug#10397). 2012-10-08 Jan Djärv * nsfont.m (Vfonts_in_cache): New variable. (nsfont_open): Use unsignedLongLongValue for cache in case wide ints are used. Add cached fonts to Vfonts_in_cache. (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache. 2012-10-08 Juanma Barranquero * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now in nt/config.nt. (FONT_H): Define after FRAME_H. ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)): Update dependencies. * w32term.c: Remove leftover declaration of keyboard_codepage. 2012-10-08 Eli Zaretskii * makefile.w32-in (FONT_H): Add $(FRAME_H). (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H). ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies. (GLOBAL_SOURCES): Add cygw32.c. ($(BLD)/unexw32.$(O)): ($(BLD)/w32.$(O)): ($(BLD)/w32console.$(O)): ($(BLD)/w32fns.$(O)): ($(BLD)/w32heap.$(O)): ($(BLD)/w32menu.$(O)): ($(BLD)/w32proc.$(O)): Add w32common.h. * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now 'const char *'. (x_to_w32_color): Don't modify the argument, modify a copy instead. 2012-10-08 Daniel Colascione * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY) (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close accidental message numbering hole. Change other messages to match. * w32select.h (HAVE_W32SELECT): Remove. * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include w32common.h instead of w32heap.h. * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size) (get_allocation_unit, get_processor_type, get_w32_major_version) (get_w32_minor_version, sysinfo_cache, osinfo_cache) (w32_major_version, w32_minor_version, w32_build_number, OS_9X) (OS_NT, os_subtype, cache_system_info): Move declarations to w32common. * w32heap.c: Include w32common.h. (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version) (w32_minor_version, w32_build_number, w32_subtype): Remove duplicate definitions. * w32fns.c: Include w32common.h; include w32heap.h only in WINDOWSNT. (Fx_file_dialog): Clarify comment on GetOpenFileName structure. Use `report_file_error' instead of `error' in order to better inform users of what went wrong. Increase NTGUI_UNICODE file dialog box file name length to 32k, the maximum allowed by the NT kernel. * w32common.h: New file. (ROUND_UP, ROUND_DOWN, get_page_size) (get_allocation_unit, get_processor_type, get_w32_major_version) (get_w32_minor_version, sysinfo_cache, osinfo_cache) (w32_major_version, w32_minor_version, w32_build_number, OS_9X) (OS_NT, os_subtype, cache_system_info): Move here. * unexw32.c, unexcw.c: Include w32common.h. * emacs.c (main): Use (defined (WINDOWSNT) || defined HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether to call syms_of_w32select. * cygw32.h: Remove obsolete EXFUN declarations. * cygw32.c (Qutf_16_le): Rename to Qutf_16le. * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal of w32inevt.o from SOME_MACHINE_OBJECTS. 2012-10-08 Daniel Colascione * image.c: Permanent fix for JPEG compilation issue --- limit jpeglib `boolean' redefinition to Cygwin builds. 2012-10-08 Eli Zaretskii * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used. * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on Cygwin. 2012-10-08 Daniel Colascione * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c, w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c, w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h, w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h, keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c, emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h, Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is now a supported configuration. * Makefile.in: consolidate image variables into LIBIMAGE; add W32_OBJ and W32_LIBS. Compile new files. * conf_post.h: (_DebPrint) declare tracing facility for W32 debugging. We need to unify tracing later. (NTGUI_UNICODE) Define when compiling for Cygwin to allow the unconditional use of W32 Unicode functions. Cygwin runs only on 100% Unicode operating systems. * cygw32.c: New file. Define Cygwin-specific facilities. (Fcygwin_convert_path_to_windows) (Fcygwin_convert_path_from_windows): New user functions for accessing Cygwin path-munging routines. * cygw32.h: New file. (WCSDATA, to_unicode, from_unicode): Define facilities for storing UTF-16LE strings temporarily inside non-Lisp-visible string objects. (w32_strerror): Just what it says on the tin. * emacs.c: Make the NS fork-then-exec code for daemon-launching also run for Cygwin; both systems have the same problem with using GUI facilities in a forked child. Also call syms_of_cygw32, syms_of_w32select in correct places. (DAEMON_MUST_EXEC): new macro defined to signal that a platform needs fork-then-exec for daemon launching. * font.h: Include frame.h. * image.c: Use the image library cache machinery only when we're compiling for native WINDOWSNT; Cygwin can use shared libraries like any other Unixlike system. * keyboard.c: Clarify a comment regarding the input loop. * menu.c: When NTGUI_UNICODE is defined, use Unicode menu functions directly instead of trying to detect at runtime that our host operating system supports them. We make this change for two reasons: Cygwin lacks support for the multibyte character conversion functions used by the legacy menu code, and Cygwin never needs to rely on non-Unicode APIs. * unexw32.c (hinst): Declare extern. * w32.c: Change header order; (w32_strerror): Move to w32fns.c because we need it for non-WINDOWSNT builds. * w32.h: Add #error macro to make sure we don't include w32.h for Cygwin builds. Remove w32select declarations. * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to w32fns.c. w32console.c is WINDOWSNT-only. * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more POSIXy alternative. (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask) (w32_major_version, w32_minor_version, w32_build_number) (os_subtype, sound_type): Define here (w32_defined_color): Make color parameter const for consistency with other _defined_color functions. (w32_createwindow): Unconditionally call w32_init_class instead of doing so only when hprevinst is non-NULL. Plumbing hprevinst through the code is complex and unnecessary because class registration is practically free. (w32_name_of_message): New EMACSDEBUG-only function. (Fset_message_beep): Move here (Fx_open_connection): Require that the display name for Windows be "w32" for consistency, emacsclient disambiguation, and maybe, one day, multi-window-system support. (file_dialog_callback): NTGUI_UNICODE changes; encode and decode Cygwin files for W32 GUI facilities, since these clearly don't expect Cygwin names. (_DebPrint): Define. (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs) (w32_kbd_patch_key, w32_sys_ring_bell): Move here. (Ssystem_move_file_to_trash): Define only for native WINDOWSNT. (w32_last_error): Remove. * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds. * w32heap.c (syspage_mask): Declare here. (cache_system_info): Remove. * w32inevt.c (faked_key): Define globally, not statically. (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key) (w32_console_toggle_lock_key): Move to w32fns.c. * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout. * w32proc.c (_DebPrint): Move to w32fns.c. * w32select.c: Include string.h, stdio.h for Cygwin. * w32select.h: New File. * w32term.c: Include io.h for non-CYGWIN builds; needed for get_osfhandle. (w32_message_fd): New variable. Under Cygwin, holds the file descriptor the system used to tell us about pending thread messages. (w32_init_term): Remove incorrect calls to fcntl and init_sigio that prevented compilation under non-WINDOWSNT systems. (w32_initialize): Open /dev/windows and assign it to w32_message_fd. Provide w32 feature. * w32term.h: Include frame.h, atimer.h. Declare various frame functions. (WM_EMACS_INPUT_READY): add. (prepend_msg, w32_message_fd): Declare globally. * w32xfns.c: (keyboard_handle): Use only when WINDOWSNT. (notify_msg_ready): New function. Posts a message to the main thread's message queue under CYGWIN, which wakes up the main thread from select(2) by making the /dev/windows file descriptor ready. Under WINDOWSNT, it sets an event the same way the old code did. (post, prepend_msg): Actually call notify_msg_ready instead of setting the input event directly. 2012-10-07 Eli Zaretskii * ralloc.c (relinquish): If a heap is ready to be relinquished, but it still has blocs in it, don't return it to the system, instead of aborting. (Bug#12402) 2012-10-07 Jan Djärv * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506). * nsterm.m (ns_update_auto_hide_menu_bar): Remove definition of MAC_OS_X_VERSION_10_6. (syms_of_nsterm): Remove comment about Panther and above for ns-antialias-text. * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove. (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4. (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3. * nsselect.m (ns_string_from_pasteboard): Remove check for >= MAC_OS_X_VERSION_10_4. * nsmenu.m (fillWithWidgetValue:): Remove code for < MAC_OS_X_VERSION_10_2. * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger. * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4. (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4. * nsterm.m (ns_in_resize): Remove (Bug#12479). (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove. (ns_clear_frame, sendEvent, windowDidResize, drawRect:): Remove ns_in_resize check. (ns_clear_frame_area): Remove resize handle code. * nsfns.m (ns_in_resize): Remove. (x_set_icon_name, ns_set_name, ns_set_name_as_filename): Remove ns_in_resize check. 2012-10-07 Paul Eggert Improve sys_siglist detection. * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's defined as a macro, as is done in Solaris. (sys_siglist_entries): New macro. (save_strsignal): Use it. * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection. 2012-10-06 Jan Djärv * nsfns.m (Fx_create_frame): Call x_default_parameter with fullscreen/Fullscreen. * nsterm.h (EmacsView): Rename tbar_height to tibar_height. tobar_height is new. * nsterm.m (x_make_frame_visible): Check for fullscreen. (ns_fullscreen_hook): Activate old style fullscreen with a timer. (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen. (windowDidResize:): Check for correct window if old style fullscreen. Capitalize word in comment. Remove incorrect comment. (initFrameFromEmacs:): tbar_height renamed tibar_height. (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix error in drawing background. (toggleFullScreen:): Remove comment. Rearrange calls. Set toolbar values to zero, save old height in tobar_height. Restore tool bar height when leaving fullscreen. (canBecomeMainWindow): New function. 2012-10-06 Paul Eggert * keyboard.c (read_char): Remove unnecessary 'volatile's and label. 2012-10-05 Eli Zaretskii * w32proc.c (stop_timer_thread): Fix declaration of 'err'. * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so that time stamps of directories could also be changed. Don't request the too broad GENERIC_WRITE, only the more restrictive FILE_WRITE_ATTRIBUTES access rights. * fileio.c (Fset_file_times): Special-case ignoring errors for directories only on MSDOS, not on MS-Windows. 2012-10-05 Ikumi Keita (tiny change) * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555) 2012-10-04 Eli Zaretskii * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to see whether CreateFile failed. 2012-10-04 Paul Eggert * profiler.c (handle_profiler_signal): Inhibit pending signals too, to avoid similar races. * keyboard.c (pending_signals): Now bool, not int. Port timers to OpenBSD, plus check for timer failures. OpenBSD problem reported by Han Boetes. * profiler.c (setup_cpu_timer): Check for failure of timer_settime and/or setitimer. (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER. * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms like OpenBSD, which has timer_settime but does not declare it. OpenBSD does not define SIGEV_SIGNAL, so use that when deciding whether to use itimerspec-related primitives. All uses of HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC. 2012-10-02 Paul Eggert * profiler.c (handle_profiler_signal): Fix a malloc race that caused Emacs to hang on Fedora 17 when profiling Lisp. 2012-10-02 Jan Djärv * nsterm.m (windowDidEnterFullScreen): Remove fprintf. 2012-10-02 Eli Zaretskii * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be consistent with the change in return value of 'safe_strsignal'. 2012-10-02 Paul Eggert Prefer plain 'static' to 'static inline' (Bug#12541). * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category) (bidi_set_sor_type, bidi_push_embedding_level) (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it) (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state) (bidi_cache_search, bidi_cache_ensure_space) (bidi_cache_iterator_state, bidi_cache_find) (bidi_peek_at_next_level, bidi_set_paragraph_end) (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char) (bidi_explicit_dir_char, bidi_resolve_neutral_1): Now 'static', not 'static inline'. Count overruns when profiling; change units to ns. * profiler.c (handle_profiler_signal): Count sampling intervals, not ms. Give extra weight to samples after overruns, to attempt to count the time more accurately. (setup_cpu_timer): Change sampling interval units from ms to ns, since the underlying primitives nominally do ns. (Fprofiler_cpu_start): Document the change. Mention that the sampling intervals are only approximate. 2012-10-02 Stefan Monnier * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP. * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special case for the special 0 coding-system. * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening. (Fmake_overlay): Remove redundant tests. (fix_start_end_in_overlays): Remove redundant recentering. 2012-10-02 Juanma Barranquero * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)): Update dependencies. 2012-10-01 Paul Eggert Fix a malloc race condition involving strsignal. A signal can arrive in the middle of a malloc, and Emacs's signal handler can invoke strsignal, which can invoke malloc, which is not portable. This race condition bug makes Emacs hang on GNU/Linux. Fix it by altering the signal handler so that it does not invoke strsignal. * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal. * process.c (status_message): Use const pointer, in case strsignal is #defined to safe_strsignal. * sysdep.c (sys_siglist, init_signals): Always define and initialize a substitute sys_siglist if the system does not define one, even if HAVE_STRSIGNAL. (safe_strsignal): Rename from strsignal. Always define, using sys_siglist. Return a const pointer. * syssignal.h (safe_strsignal): New decl. (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal. 2012-10-01 Eli Zaretskii * w32proc.c (timer_loop): Fix code that waits for timer expiration, to avoid high CPU usage. 2012-10-01 Stefan Monnier * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table) (sweep_weak_table): Remove redundant prototypes. 2012-10-01 Fabrice Popineau * emacs.c: Move the inclusion of TERM_HEADER after including windows.h on WINDOWSNT. This avoids compilation problems with MSVC. 2012-10-01 Eli Zaretskii * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET) (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses. (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *', as the previous version used 'void *'. * ralloc.c (ROUNDUP): Fix last change. (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type 'size_t'. * w32proc.c : New static flag. (init_timers): Initialize it to zero, after creating the critical sections used by the timer threads. (term_timers): Set to 1 before deleting the critical sections. (getitimer, setitimer): If disable_itimers is non-zero, return an error indication without doing anything. Reported by Fabrice Popineau as part of bug#12544. (alarm) [HAVE_SETITIMER]: Be more conformant to the expected return results. [!HAVE_SETITIMER]: Behave as the previous version that didn't support timers. * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to term_ntproc after all the other bookkeeping, to get timers working as long as possible. 2012-10-01 Paul Eggert * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100. Suggested by Juri Linkov in . Prefer plain 'static' to 'static inline' (Bug#12541). With static functions, modern compilers inline pretty well by themselves; advice from programmers often hurts as much as it helps. On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'), this change shrinks the text size of the Emacs executable by 1.1% without affecting CPU significantly in my benchmark. * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p) (live_float_p, live_misc_p, live_vector_p, live_buffer_p) (mark_maybe_object, mark_maybe_pointer, bounded_number): * buffer.c (bset_abbrev_mode, bset_abbrev_table) (bset_auto_fill_function, bset_auto_save_file_format) (bset_auto_save_file_name, bset_backed_up, bset_begv_marker) (bset_bidi_display_reordering, bset_buffer_file_coding_system) (bset_cache_long_line_scans, bset_case_fold_search) (bset_ctl_arrow, bset_cursor_in_non_selected_windows) (bset_cursor_type, bset_display_table, bset_extra_line_spacing) (bset_file_format, bset_file_truename, bset_fringe_cursor_alist) (bset_fringe_indicator_alist, bset_fringes_outside_margins) (bset_header_line_format, bset_indicate_buffer_boundaries) (bset_indicate_empty_lines, bset_invisibility_spec) (bset_left_fringe_width, bset_major_mode, bset_mark) (bset_minor_modes, bset_mode_line_format, bset_mode_name) (bset_name, bset_overwrite_mode, bset_pt_marker) (bset_right_fringe_width, bset_save_length) (bset_scroll_bar_width, bset_scroll_down_aggressively) (bset_scroll_up_aggressively, bset_selective_display) (bset_selective_display_ellipses, bset_vertical_scroll_bar_type) (bset_word_wrap, bset_zv_marker, set_buffer_overlays_before) (set_buffer_overlays_after): * category.c (bset_category_table): * charset.c (read_hex): * coding.c (produce_composition, produce_charset) (handle_composition_annotation, handle_charset_annotation) (char_encodable_p): * dispnew.c (swap_glyph_pointers, copy_row_except_pointers) (assign_row, set_frame_matrix_frame, make_current) (add_row_entry): * eval.c (set_specpdl_symbol, set_specpdl_old_value): * fns.c (maybe_resize_hash_table): * frame.c (fset_buffer_predicate, fset_minibuffer_window): * gmalloc.c (register_heapinfo): * image.c (lookup_image_type): * intervals.c (set_interval_object, set_interval_left) (set_interval_right, copy_interval_parent, rotate_right) (rotate_left, balance_possible_root_interval): * keyboard.c (kset_echo_string, kset_kbd_queue) (kset_keyboard_translate_table, kset_last_prefix_arg) (kset_last_repeatable_command, kset_local_function_key_map) (kset_overriding_terminal_local_map, kset_real_last_command) (kset_system_key_syms, clear_event, set_prop): * lread.c (digit_to_number): * marker.c (attach_marker, live_buffer, set_marker_internal): * nsterm.m (ns_compute_glyph_string_overhangs): * process.c (pset_buffer, pset_command) (pset_decode_coding_system, pset_decoding_buf) (pset_encode_coding_system, pset_encoding_buf, pset_filter) (pset_log, pset_mark, pset_name, pset_plist, pset_sentinel) (pset_status, pset_tty_name, pset_type, pset_write_queue): * syntax.c (bset_syntax_table, dec_bytepos): * terminal.c (tset_param_alist): * textprop.c (interval_has_some_properties) (interval_has_some_properties_list): * window.c (wset_combination_limit, wset_dedicated) (wset_display_table, wset_hchild, wset_left_fringe_width) (wset_left_margin_cols, wset_new_normal, wset_new_total) (wset_normal_cols, wset_normal_lines, wset_parent, wset_pointm) (wset_right_fringe_width, wset_right_margin_cols) (wset_scroll_bar_width, wset_start, wset_temslot, wset_vchild) (wset_vertical_scroll_bar_type, wset_window_parameters): * xdisp.c (wset_base_line_number, wset_base_line_pos) (wset_column_number_displayed, wset_region_showing) (window_box_edges, run_window_scroll_functions) (append_glyph_string_lists, prepend_glyph_string_lists) (append_glyph_string, set_glyph_string_background_width) (append_glyph, append_composite_glyph) (take_vertical_position_into_account): * xfaces.c (x_create_gc, x_free_gc, merge_face_vectors) (face_attr_equal_p, lface_equal_p, hash_string_case_insensitive) (lface_hash, lface_same_font_attributes_p, lookup_face): * xml.c (libxml2_loaded_p): * xterm.c (x_set_mode_line_face_gc, x_set_glyph_string_gc) (x_set_glyph_string_clipping, x_clear_glyph_string_rect): Now 'static', not 'static inline'. * bidi.c: Tune.

(Fgnutls_available_p): Caller changed. * xml.c (init_libxml2_functions, Flibxml_parse_html_region) (Flibxml_parse_xml_region): Likewise. * dispextern.h (struct image_type): Remove arg from init function. * image.c (Finit_image_library, lookup_image_type) (define_image_type): Remove now-unneeded second arg. (init_xpm_functions, init_png_functions, init_jpeg_functions) (init_tiff_functions, init_gif_functions, init_svg_functions): Arglist and w32_delayed_load calling convention changed. (gs_type): Remove init_gs_functions; there is no such function. (valid_image_p, make_image): Fix caller to lookup_image_type. 2012-09-23 Paul Eggert Simplify and avoid signal-handling races (Bug#12471). * alloc.c (die): * sysdep.c (emacs_abort) [HAVE_NTGUI]: Avoid recursive loop if there's a fatal error in the function itself. * atimer.c (pending_atimers): * blockinput.h: Don't include "atimer.h"; no longer needed. (interrupt_input_pending): Remove. All uses removed. pending_signals now counts both atimers and ordinary interrupts. This is less racy than having three separate pending-signal flags. (block_input, unblock_input, totally_unblock_input, unblock_input_to) (input_blocked_p): Rename from their upper-case counterparts BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO, INPUT_BLOCKED_P, and turn into functions. All uses changed. This makes it easier to access volatile variables more accurately. (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input (). (input_blocked_p): Prefer this to 'interrupt_input_blocked', as that's more reliable if the code is buggy and sets interrupt_input_blocked to a negative value. All uses changed. * atimer.c (deliver_alarm_signal): Remove. No need to deliver this to the parent; any thread can handle this signal now. All uses replaced by underlying handler. * atimer.c (turn_on_atimers): * dispnew.c (handle_window_change_signal): * emacs.c (handle_danger_signal): * keyboard.c (kbd_buffer_get_event): Don't reestablish signal handler; not needed with sigaction. * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT) (UNBLOCK_INPUT_TO): Rework to avoid unnecessary accesses to volatile variables. (UNBLOCK_INPUT_TO): Now a function. (totally_unblock_input, unblock_input): New decls. * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c (init_data): Remove. Necessary stuff now done in init_signal. * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions. * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c. (fatal_error_code): Remove; no longer needed. (terminate_due_to_signal): Rename from fatal_error_backtrace, since it doesn't always backtrace. All uses changed. No need to reset signal to default, since sigaction and/or die does that for us now. Use emacs_raise (FOO), not kill (getpid (), FOO). (main): Check more-accurately whether we're dumping. Move fatal-error setup to sysdep.c * floatfns.c: Do not include "syssignal.h"; no longer needed. * gtkutil.c (xg_get_file_name, xg_get_font): Remove no-longer-needed signal-mask manipulation. * keyboard.c, process.c (POLL_FOR_INPUT): Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined. * keyboard.c (read_avail_input): Remove. All uses replaced by gobble_input. (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code. (kbd_buffer_store_event_hold, gobble_input): (record_asynch_buffer_change) [USABLE_SIGIO]: (store_user_signal_events): No need to mess with signal mask. (gobble_input): If blocking input and there are terminals, simply set pending_signals to 1 and return. All hooks changed to not worry about whether input is blocked. (process_pending_signals): Clear pending_signals before processing them, in case a signal comes in while we're processing. By convention callers now test pending_signals before calling us. (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input): New functions, to support changes to blockinput.h. (handle_input_available_signal): Now extern. (reinvoke_input_signal): Remove. All uses replaced by handle_async_input. (quit_count): Now volatile, since a signal handler uses it. (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All callers changed. Block SIGINT only if not already blocked. Clear sigmask reliably, even if Fsignal returns, which it can. Omit unnecessary accesses to volatile var. (quit_throw_to_read_char): No need to restore sigmask. * keyboard.c (gobble_input, handle_user_signal): * process.c (wait_reading_process_output): Call signal-handling code rather than killing ourselves. * lisp.h: Include , for... (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication. (pending_signals): Now volatile. (syms_of_data): Now const if IEEE floating point. (handle_input_available_signal) [USABLE_SIGIO]: (terminate_due_to_signal, record_child_status_change): New decls. * process.c (create_process): Avoid disaster if memory is exhausted while we're processing a vfork, by tightening the critical section around the vfork. (send_process_frame, process_sent_to, handle_pipe_signal) (deliver_pipe_signal): Remove. No longer needed, as Emacs now ignores SIGPIPE. (send_process): No need for setjmp/longjmp any more, since the SIGPIPE stuff is now gone. Instead, report an error if errno is EPIPE. (record_child_status_change): Now extern. PID and W are now args. Return void, not bool. All callers changed. * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]: Remove. All uses removed. This bug should be fixed now in a different way. (wait_for_termination_1): Use waitpid rather than sigsuspend, and record the child status change directly. This avoids the need to futz with the signal mask. (process_fatal_action): Move here from emacs.c. (emacs_sigaction_flags): New function, containing much of what used to be in emacs_sigaction_init. (emacs_sigaction_init): Use it. Block nonfatal system signals that are caught by emacs, to make races less likely. (deliver_process_signal): Rename from handle_on_main_thread. All uses changed. (BACKTRACE_LIMIT_MAX): Now at top level. (thread_backtrace_buffer, threadback_backtrace_pointers): New static vars. (deliver_thread_signal, deliver_fatal_thread_signal): New functions, for more-accurate delivery of thread-specific signals. (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c. (deliver_arith_signal): Handle in this thread, not in the main thread, since it's triggered by this thread. (maybe_fatal_sig): New function. (init_signals): New arg DUMPING so that we can be more accurate about whether we're dumping. Caller changed. Treat thread-specific signals differently from process-general signals. Block all signals while handling fatal error; that's safer. xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal on IEEE hosts. When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored. Ignore SIGPIPE unless batch. (emacs_backtrace): Output backtrace for the appropriate thread, which is not necessarily the main thread. * syssignal.h: Include . (emacs_raise): New macro. * xterm.c (x_connection_signal): Remove; no longer needed now that we use sigaction. (x_connection_closed): No need to mess with sigmask now. (x_initialize): No need to reset SIGPIPE handler here, since init_signals does this for us now. 2012-09-23 Jan Djärv * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into, background rect may be larger (Bug#12245). 2012-09-23 Chong Yidong * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence. 2012-09-22 Paul Eggert * .gdbinit: Just stop at fatal_error_backtrace. See Stefan Monnier's request in . Remove no-longer-used query of system type. 2012-09-22 Chong Yidong * search.c (Freplace_match): Doc fix (Bug#12325). * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391). * editfns.c (Fline_beginning_position): Doc fix (Bug#12416). (Fline_end_position): Doc fix. * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414). 2012-09-22 Chong Yidong * dispextern.h (struct image_type): Add new slot, storing a type initialization function. * image.c (define_image_type): Call the image initializer function if it is defined. Arguments and return value changed. (valid_image_p, make_image): Callers changed. (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type) (gif_type, imagemagick_type, svg_type, gs_type): Add initialization functions. (Finit_image_library): Call lookup_image_type. (CHECK_LIB_AVAILABLE): Macro deleted. (lookup_image_type): Call define_image_type here, rather than via Finit_image_library, and without using CHECK_LIB_AVAILABLE. (syms_of_image): Move define_image_type calls for xbm_type and pbm_type to lookup_image_type. 2012-09-22 Eli Zaretskii * keyboard.c (timer_check_2): Move calculation of 'timers' and 'idle_timers' from here ... (timer_check): ... to here. Use Fcopy_sequence to copy the timer lists, to avoid infloops when the timer does something stupid, like reinvoke itself with the same or smaller time-out. (Bug#12447) 2012-09-22 Martin Rudalics * window.c (Fsplit_window_internal): Handle only Qt value of Vwindow_combination_limit separately. (Qtemp_buffer_resize): New symbol. (Vwindow_combination_limit): New default value. Rewrite doc-string. 2012-09-22 Eli Zaretskii * xdisp.c (next_overlay_string): Initialize it->end_charpos for the new overlay string. (Bug#10159) 2012-09-22 Paul Eggert * emacs.c (shut_down_emacs): Don't assume stderr is buffered, or that fprintf is async-signal-safe. POSIX doesn't require either assumption. 2012-09-22 Chong Yidong * buffer.c (Fset_buffer_modified_p): Handle indirect buffers (Bug#8207). 2012-09-22 Kenichi Handa * composite.c (composition_reseat_it): Handle the case that a grapheme cluster is not covered by a single font (Bug#12352). 2012-09-21 Chong Yidong * image.c (define_image_type): Avoid adding duplicate types to image_types (Bug#12463). Suggested by Jörg Walter. 2012-09-21 YAMAMOTO Mitsuharu * unexmacosx.c: Define LC_DATA_IN_CODE if not defined. (print_load_command_name): Add case LC_DATA_IN_CODE. (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data. 2012-09-21 Glenn Morris * eval.c (Frun_hook_with_args_until_success) (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393) 2012-09-21 Andreas Schwab * fileio.c (Ffile_selinux_context): Only call freecon when lgetfilecon succeeded. (Fset_file_selinux_context): Likewise. (Bug#12444) 2012-09-21 Eli Zaretskii * xdisp.c (try_window_reusing_current_matrix): Under bidi reordering, locate the cursor by calling set_cursor_from_row; if that fails, clear the desired glyph matrix before returning a failure indication to the caller. Fixes leaving garbled display when fast scrolling with a down-key. (Bug#12403) (compute_stop_pos_backwards): Fix a typo that caused crashes while scrolling through multibyte text. 2012-09-20 Stefan Monnier * alloc.c (mark_object) : Mark prev/next_buffers *after* calling mark_vectorlike since that's the one that marks the window. (mark_discard_killed_buffers): Mark the final cdr. * window.h (struct window): Move prev/next_buffers to the non-standard fields. * window.c (make_window): Initialize prev/next_buffers manually. 2012-09-20 Paul Eggert Omit unused arg EXPECTED from socket hooks. * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input): * nsterm.m (ns_term_init): * termhooks.h (struct terminal.read_socket_hook): * w32inevt.c (w32_console_read_socket): * w32term.c (w32_read_socket): * xterm.c (XTread_socket): Omit unused arg EXPECTED. All callers changed. (store_user_signal_events): Return void, not int, since callers no longer care about the return value. All uses changed. 2012-09-20 Juanma Barranquero * w32gui.h (XParseGeometry): Do not declare. 2012-09-19 Paul Eggert * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0. Ignore 'expected'. See Eli Zaretskii in (last line). * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul. (XParseGeometry): Now static. Substitute extremal values for values that are out of range. 2012-09-19 Jan Djärv * w32xfns.c (read_integer, XParseGeometry): Move to frame.c. * nsfns.m (XParseGeometry): Remove. (Fx_create_frame): Call x_set_offset to correctly interpret top_pos in geometry. * frame.c (read_integer, XParseGeometry): Move from w32xfns.c. (Fx_parse_geometry): If there is a space in string, call Qns_parse_geometry, otherwise do as on other terms (Bug#12368). 2012-09-17 Eli Zaretskii * search.c (scan_buffer): Use character positions in calls to region_cache_forward and region_cache_backward, not byte positions. (Bug#12196) * w32term.c (w32_read_socket): Set pending_signals to 1, like xterm.c does. Reported by Daniel Colascione . * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize __malloc_extra_blocks to 32 instead of 64, like alloc.c did in emacs_blocked_malloc, now deleted. 2012-09-17 Paul Eggert Remove no-longer-needed Solaris 2.4 vfork bug workaround. The workaround was for improving performance on Solaris 2.4, but is getting in the way now. Emacs will still work if someone is still running Solaris 2.4 in a museum somewhere; Sun dropped support for Solaris 2.4 in 2003. * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]: * process.c (create_process) [HAVE_WORKING_VFORK]: Omit now-unnecessary workaround for the Solaris 2.4 vfork bug, since Emacs no longer uses vfork on that platform. 2012-09-17 Glenn Morris * emacs.c: Use COPYRIGHT. 2012-09-16 Paul Eggert Remove configure's --without-sync-input option (Bug#12450). When auditing signal-handling in preparation for cleaning it up, I found that SYNC_INPUT has race conditions and would be a real pain to fix. Since it's an undocumented and deprecated configure-time option, now seems like a good time to remove it. Also see . * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal) (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls. (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]: (malloc_hysteresis): (check_depth) [XMALLOC_OVERRUN_CHECK]: (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED) (dont_register_blocks, bytes_used_when_reconsidered) (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc) (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc): [!SYSTEM_MALLOC && !SYNC_INPUT]: Remove. All uses removed. (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different implementation, one that depends on whether the new macro XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT is defined. * atimer.c (run_timers, handle_alarm_signal): * keyboard.c (pending_signal, poll_for_input_1, poll_for_input) (handle_async_input, process_pending_signals) (handle_input_available_signal, init_keyboard): * nsterm.m (ns_read_socket): * process.c (wait_reading_process_output): * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK): * sysdep.c (emacs_sigaction_init) [SA_RESTART]: (emacs_write): * xterm.c (XTread_socket): Assume SYNC_INPUT. * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef. * eval.c (handling_signal): Remove. All uses removed. * lisp.h (ELSE_PENDING_SIGNALS): Remove. All uses replaced with the SYNC_INPUT version. (reset_malloc_hooks, uninterrupt_malloc, handling_signal): Remove decls. * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Now static. * font.c (Ffont_shape_gstring): Remove unused local. 2012-09-16 Glenn Morris * Makefile.in (clean): No longer run nextstep's clean. * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables. (ns_frag): Remove. (ns-app): Move here from ns.mk, and simplify. (clean): Simplify nextstep entry. * ns.mk: Remove file. 2012-09-17 Kenichi Handa * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may not convert the last few characters. 2012-09-16 Kenichi Handa * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster here, but just check the validity of glyphs in the glyph-string. 2012-09-16 Martin Rudalics * window.c (Fwindow_parameter, Fset_window_parameter): Accept any window as argument (Bug#12452). 2012-09-16 Jan Djärv * nsfns.m (Fx_open_connection): Move initialization of ns_*_types to ns_term_init to avoid memory leak. * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use explicit retain/release. (ns_term_init): Only allow one display. Initialize outerpool and ns_*_types. 2012-09-15 Paul Eggert Port _setjmp fix to POSIXish hosts as well as Microsoft. * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as it's needed on POSIXish hosts that lack _setjmp. Attempt to solve the Microsoft problem in a different way, by altering ../nt/config.nt. 2012-09-15 Eli Zaretskii * w32xfns.c: * w32uniscribe.c: * w32term.c: * w32select.c: * w32reg.c: * w32proc.c: * w32menu.c: * w32inevt.c: * w32heap.c: * w32font.c: * w32fns.c: * w32console.c: * w32.c: * w16select.c: Remove inclusion of setjmp.h, as it is now included by lisp.h. This completes removal of setjmp.h inclusion erroneously announced in the previous commit. (Bug#12446) * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary more accurate. * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is not defined as a macro. The latter happens on MS-Windows. (Bug#12446) 2012-09-15 Paul Eggert Port better to POSIX hosts lacking _setjmp (Bug#12446). * lisp.h: Include here, since we use its symbols here. Some instances of '#include ' removed, if the only reason for the instance was because "lisp.h" was included. (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols. Unless otherwise specified, replace all uses of jmp_buf, _setjmp, and _longjmp with the new symbols. Emacs already uses _setjmp if available, so this change affects only POSIXish hosts that have sigsetjmp but not _setjmp, such as some versions of Solaris and Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.) * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros. (png_load_body) [HAVE_PNG]: (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]: Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp, since PNG requires jmp_buf. This is the only exception to the general rule that we now use sys_setjmp and sys_longjmp. This exception is OK since this code does not change the signal mask or longjmp out of a signal handler. 2012-09-14 Paul Eggert * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]: Include "syssignal.h", for 'main_thread'. 2012-09-14 Dmitry Antipov Avoid out-of-range marker position (Bug#12426). * insdel.c (replace_range, replace_range_2): Adjust markers before overlays, as suggested by comments. (insert_1_both, insert_from_buffer_1, adjust_after_replace): Remove redundant check before calling offset_intervals. 2012-09-14 Martin Rudalics * xdisp.c (Fformat_mode_line): Unconditionally save/restore current buffer (Bug#12387). 2012-09-14 Juanma Barranquero * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies. 2012-09-13 Paul Eggert Use a more backwards-compatible timer format (Bug#12430). * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0) vector element, not from the 4th, since PSECS is now at the end. (Fcurrent_idle_time): Doc fix. 2012-09-13 Dmitry Antipov Function to mark objects and remove killed buffers at once. * alloc.c (discard_killed_buffers): Rename to ... (mark_discard_killed buffers) ... new name. Add marking of remaining objects. Fix comment. Adjust users. (mark_object): Do not touch frame buffer lists here. * frame.c (delete_frame): Reset frame buffer lists here. 2012-09-13 Paul Eggert Better workaround for GNOME bug when --enable-gcc-warnings. * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change. Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in . Simplify SIGIO usage (Bug#12408). The code that dealt with SIGIO was crufty and confusing, e.g., it played tricks like "#undef SIGIO" but these tricks were not used consistently. Simplify mostly by not #undeffing standard symbols, e.g., use "defined USABLE_SIGIO" (our symbol, which we can define or not as we please) rather than "defined SIGIO" (standard symbol that we probably shouldn't #undef). * conf_post.h [USG5_4]: Do not include here. Modules that need it can include it. [USG5_4 && emacs]: Likewise, do not include the streams stuff here. * dispextern.h (ignore_sigio): New decl. * emacs.c (shut_down_emacs): Invoke unrequest_sigio unconditionally, since it's now a no-op if !USABLE_SIGIO. * emacs.c (shut_down_emacs): * keyboard.c (kbd_buffer_store_event_hold): Use ignore_sigio rather than invoking 'signal' directly. * keyboard.c (USABLE_FIONREAD && USG5_4): Include , for FIONREAD. (FIONREAD, SIGIO): Do not #undef. (tty_read_avail_input): Use #error rather than a syntax error. * process.c [USG5_4]: Include and , for I_PIPE, used by SETUP_SLAVE_PTY. (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD. * sysdep.c (croak): Remove; no longer needed. This bit of temporary code, with Fred N. Fish's comment that it's temporary, has been in Emacs since at least 1992! (init_sigio, reset_sigio, request_sigio, unrequest_sigio): Arrange for them to be no-ops in all cases when ! USABLE_SIGIO. * syssignal.h (croak): Remove decl. (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile. * systty.h [!NO_TERMIO]: Do not include ; no longer needed now that we're termios-only. (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef. * term.c (dissociate_if_controlling_tty): Use #error rather than a run-time error. Work around GCC and GNOME bugs when --enable-gcc-warnings. * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify', to work around GNOME bug 683906. * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber. (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp. This works around GCC bug 54561. 2012-09-12 Paul Eggert More fixes for 'volatile' and setjmp/longjmp. * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's. * image.c (struct png_load_context) [HAVE_PNG]: New type. (png_load_body) [HAVE_PNG]: (jpeg_load_body) [HAVE_JPEG]: New function, with most of the old parent function's body. (png_load) [HAVE_PNG]: (jpeg_load) [HAVE_JPEG]: Invoke the new function, to avoid longjmp munging our locals. (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code. (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when longjmp is passed 2, as the C standard doesn't guarantee this. Instead, store the failure code into mgr->failure_code. 2012-09-12 Stefan Monnier * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p) (Fdiscard_input, quit_throw_to_read_char, init_keyboard) (syms_of_keyboard): Remove support for unread-command-char. 2012-09-12 Eli Zaretskii * w32proc.c (sys_kill): If PID is our process ID and the signal is SIGABRT, call emacs_abort. Avoids silently exiting upon assertion violation. (Bug#12426) 2012-09-12 Paul Eggert * image.c (jpeg_memory_src): Don't assume string len fits in unsigned. 2012-09-12 Stefan Monnier * eval.c: Add `inhibit-debugger'. (Qinhibit_debugger): New symbol. (call_debugger): Bind it instead of Qdebug_on_error. (maybe_call_debugger): Test Vinhibit_debugger. (syms_of_eval): Define inhibit-debugger. * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message. (syms_of_xdisp): Remove inhibit-debug-on-message. 2012-09-11 Paul Eggert Avoid _setjmp/_longjmp problems with local nonvolatile variables. If a nonvolatile local variable is written before a _longjmp to the frame containing the variable, and is read after the _longjmp, the value read is indeterminate. Some local variables of type 'struct handler' and 'struct catchtag' are used in this way, so mark each of their slots as volatile if the slot can be set before _longjmp and read afterwards. * lisp.h (struct handler): var and chosen_clause are now volatile. (struct catchtag): val, next, and pdlcount are now volatile. * bidi.c (bidi_push_it, bidi_pop_it): * fns.c (copy_hash_table): * image.c (define_image_type): * keyboard.c (kbd_buffer_store_event_hold): * process.c (Fprocess_send_eof): * xfaces.c (x_create_gc) [HAVE_NS]: * xgselect.c (xg_select): Prefer assignment to memcpy when either will do. * alloc.c (discard_killed_buffers): Tune and simplify a bit. Use pointer-to-a-pointer to simplify and avoid a NILP check each time an item is removed. No need to mark this function 'inline'; the compiler knows better than we do. 2012-09-11 Jan Djärv * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize. (updateFrameSize:): Add delay parameter to updateFrameSize, send it to change_frame_size (Bug#12388). (windowDidResize:): Pass YES to updateFrameSize. * nsterm.h: Add delay parameter to updateFrameSize. 2012-09-11 Dmitry Antipov Discard killed buffers from deleted window and frame objects. This reduces an amount of references to killed buffers and helps GC to reclaim them faster. * alloc.c (discard_killed_buffers): New function. (mark_object): Use it for deleted windows and frames. (mark_object): If symbol's value is set up for a killed buffer or deleted frame, restore its global binding. * data.c (swap_in_global_binding): Add GC notice. (swap_in_symval_forwarding): Use convenient set_blv_where. * window.c (wset_next_buffers, wset_prev_buffers): Move ... * window.h: ... to here. 2012-09-11 Dmitry Antipov Convenient macro to check whether the buffer is live. * buffer.h (BUFFER_LIVE_P): New macro. * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c: * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it. 2012-09-11 YAMAMOTO Mitsuharu * xdisp.c (right_overwritten, right_overwriting): Also handle gstring composition cases (Bug#12364). * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left overhang of succeeding glyphs overlapping box cursor. * w32term.c (x_draw_glyph_string): Likewise. 2012-09-11 Paul Eggert Simplify, document, and port floating-point (Bug#12381). The porting part of this patch fixes bugs on non-IEEE platforms with frexp, ldexp, logb. * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error): Now static. * floatfns.c: Simplify discussion of functions that Emacs doesn't support, by removing commented-out code and briefly listing the C89 functions excluded. The commented-out stuff was confusing maintenance, e.g., we thought we needed cbrt but it was commented out. (logb): Remove decl; no longer needed. (isfinite): New macro, if not already supplied. (isnan): Don't replace any existing macro. (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp are present on all C89 platforms. (Ffrexp): Do not special-case zero, as frexp does the right thing for that case. (Flogb): Do not use logb, as it doesn't have the desired meaning on hosts that use non-base-2 floating point. Instead, stick with frexp, which is C89 anyway. Do not pass an infinity or a NaN to frexp, to avoid getting an unspecified result. * xdisp.c (Qinhibit_debug_on_message): Now static. 2012-09-10 Jan Djärv * nsterm.m (ns_update_begin): Set clip path to whole view by using NSBezierPath (Bug#12131). 2012-09-10 Chong Yidong * fns.c (Fdelq, Fdelete): Doc fix. 2012-09-10 Paul Eggert * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL) (XSETFLOAT, XSETMISC): Parenthesize macro bodies. 2012-09-09 Stefan Monnier * lisp.h (make_lisp_ptr): New macro to replace XSET. (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC): Use it. 2012-09-09 Eli Zaretskii * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the left fringe if the window has a left margin. This avoids leaving traces of the cursor because its leftmost pixel is not drawn over. * dispnew.c (update_window_line): When the left margin area of a screen line is updated, set the redraw_fringe_bitmaps_p flag of that screen line. (Bug#12277) 2012-09-09 Paul Eggert Assume C89 or later for math functions (Bug#12381). This simplifies the code, and makes it a bit smaller and faster, and (most important) makes it easier to clean up signal handling since we can stop worring about floating-point exceptions in library code. That was a problem before C89, but the problem went away many years ago on all practical Emacs targets. * data.c, image.c, lread.c, print.c: Don't include ; no longer needed. * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it might be autoconfigured, as that never happens. * data.c (fmod): * doprnt.c (DBL_MAX_10_EXP): * print.c (DBL_DIG): Remove. C89 or later always defines these. * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN) (in_float, float_error_arg, float_error_arg2, float_error_fn_name) (arith_error, domain_error, domain_error2): Remove all this pre-C89 cruft. Do not include as that's no longer needed -- we simply return what C returns. All uses removed. (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with the wrapped code. (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2): Remove. All uses expanded, as these macros are no longer used more than once and are now more trouble than they're worth. (Ftan): Use tan, not sin / cos. (Flogb): Assume C89 frexp. (fmod_float): Assume C89 fmod. (matherr) [HAVE_MATHERR]: Remove; no longer needed. (init_floatfns): Remove. All uses removed. 2012-09-08 Jan Djärv * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back compositeToPoint for OSX < 10.6 (Bug#12390). 2012-09-08 Paul Eggert * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)). This produces more-accurate results. 2012-09-08 Jan Djärv * nsterm.m (updateFrameSize): Call setFrame: on the view when size changes (Bug#12088). 2012-09-08 Chong Yidong * syntax.c (Fstring_to_syntax): Doc fix. 2012-09-08 Jan Djärv * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe in the internal border. (x_set_window_size): Remove static variables and their usage. (ns_redraw_scroll_bars): Fix NSTRACE arg. (ns_after_update_window_line, ns_draw_fringe_bitmap): Remove fringe/internal border adjustment (Bug#11052). (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c). (ns_draw_window_cursor): Remove fringe/internal border adjustment. (ns_fix_rect_ibw): Remove. (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw. (ns_dumpglyphs_box_or_relief): Ditto. (ns_maybe_dumpglyphs_background): Remove fringe/internal border adjustment. (ns_dumpglyphs_image): Ditto. (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal border adjustment. (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and their usage. Add fringe_extended_p and its use as in other terms. (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if scroll bar was removed. (updateFrameSize): New function. (windowDidResize): Move code to updateFrameSize and call it. * nsterm.h (EmacsView): Add updateFrameSize. 2012-09-07 Chong Yidong * textprop.c (Fget_text_property): Minor doc fix (Bug#12323). * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713). 2012-09-07 Paul Eggert More signal-handler cleanup (Bug#12327). * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls. Problem introduced when merging patches. Noted by Eli Zaretskii in . * floatfns.c: Comment fix. * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER. SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right, and anyway the declaration is harmless even if SIGDANGER is not defined. * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD || defined BROKEN_FIONREAD). systty.h formerly did this, but other source files not surprisingly expected syssignal.h to define, or not define, SIGIO, and it's cleaner to do it that way, for consistency. Include , for FIONREAD. * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job. This eliminates a problem whereby other files mysteriously had to include "syssignal.h" before including "systty.h" if they wanted to use "#ifdef SIGIO". 2012-09-07 Eli Zaretskii * w32proc.c (sigaction): New function, emulates Posix 'sigaction'. * w32.c (sigemptyset): Empty the set. (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions. * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT. 2012-09-07 Dmitry Antipov * alloc.c (mark_buffer): Revert unsafe marking optimization. (mark_object): Likewise for frame objects. 2012-09-07 Paul Eggert * syssignal.h (handle_on_main_thread): Always declare, even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined. This ports to platforms without HAVE_PTHREAD. 2012-09-06 Paul Eggert Signal-handler cleanup (Bug#12327). Emacs's signal handlers were written in the old 4.2BSD style with sigblock and sigmask and so forth, and this led to some inefficiencies and confusion. Rewrite these to use pthread_sigmask etc. without copying signal sets around. Also, get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and 'signal', and instead use functions that do not attempt to take over the system name space. This patch causes Emacs's text segment to shrink by 0.7% on my platform, Fedora 17 x86-64. * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c: Do not include or "syssignal.h", as these modules do not use signals. * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c: * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c: Do not include , as "syssignal.h" does that for us now. * atimer.c (sigmask_atimers): New function. (block_atimers, unblock_atimers): New functions, replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS. All uses replaced. * conf_post.h [SIGNAL_H_AHB]: Do not include ; no longer needed here. * emacs.c (main): Inspect existing signal handler with sigaction, so that there's no need to block and unblock SIGHUP. * sysdep.c (struct save_signal): New member 'action', replacing old member 'handler'. (save_signal_handlers, restore_signal_handlers): Use sigaction instead of 'signal' to save and restore. (get_set_sighandler, set_sighandler) [!WINDOWSNT]: New function. All users of 'signal' modified to use set_sighandler if they're writeonly, and to use sys_signal if they're read+write. (emacs_sigaction_init, forwarded_signal): New functions. (sys_signal): Remove. All uses replaced by calls to sigaction and emacs_sigaction_init, or by direct calls to 'signal'. (sys_sigmask) [!__GNUC__]: Remove; no longer needed. (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove; all uses replaced by pthread_sigmask etc. calls. * syssignal.h: Include . (emacs_sigaction_init, forwarded_signal): New decls. (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t. (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask. (sigmask, sys_sigmask): Remove; no longer needed. (sigpause): Remove. All uses replaced by its definiens, sigsuspend. (sigblock, sigunblock, sigfree): (sigsetmask) [!defined sigsetmask]: Remove. All uses replaced by pthread_sigmask. (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN) no longer need to be replaced, and its typical old uses are now done via emacs_sigaction_init and sigaction. (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls. (sys_sigdel): Remove; unused. (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef. 2012-09-06 Eli Zaretskii * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327) 2012-09-06 Dmitry Antipov Explicitly mark buffer_defaults and buffer_local_symbols. * alloc.c (Fgarbage_collect): Mark buffer_defaults and mark_local_symbols here. (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking since special buffers aren't marked here any more. (allocate_buffer): Chain new buffer with all_buffers here... * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and not here. (Vbuffer_defaults, Vbuffer_local_symbols): Remove. (syms_of_buffer): Remove staticpro of the above. (init_buffer_once): Set names for buffer_defaults and buffer_local_symbols. 2012-09-06 Paul Eggert Use bool for booleans in font-related modules. * font.c (font_intern_prop, font_style_to_value) (font_style_symbolic, font_parse_xlfd, font_parse_fcname) (generate_otf_features, font_check_otf_features, font_check_otf) (font_match_p, font_list_entities, font_at): * fontset.c (fontset_id_valid_p, reorder_font_vector (fontset_find_font, Fset_fontset_font) (face_suitable_for_char_p) [0]: * ftfont.c (fc_initialized, ftfont_get_open_type_spec) (ftfont_open, ftfont_text_extents, ftfont_check_otf): (m17n_flt_initialized, ftfont_shape_by_flt): * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw): * nsfont.m (nsfont_draw): * w32font.c (w32font_draw): * w32term.c (x_draw_glyphless_glyph_string_foreground): Use bool for booleans. * font.h: Adjust to above API changes. (struct font, struct font_driver, struct font_driver_list): Use bool for booleans. (struct font): Remove useless member encoding_type. All users removed. * fontset.c, xftfont.c: Omit unnecessary static decls. 2012-09-06 Dmitry Antipov * alloc.c (mark_object): Revert window marking code since it's unsafe for the Fset_window_configuration. 2012-09-05 Paul Eggert Fix race conditions with signal handlers and errno (Bug#12327). Be more systematic about preserving errno whenever a signal handler returns, even if it's not in the main thread. Do this by renaming signal handlers to distinguish between signal delivery and signal handling. All uses changed. * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler. * data.c (deliver_arith_signal): Rename from arith_error. * dispnew.c (deliver_window_change_signal): Rename from window_change_signal. * emacs.c (deliver_error_signal): Rename from fatal_error_signal. (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal. * keyboard.c (deliver_input_available_signal): Rename from input_available_signal. (deliver_user_signal): Rename from handle_user_signal. (deliver_interrupt_signal): Rename from interrupt_signal. * process.c (deliver_pipe_signal): Rename from send_process_trap. (deliver_child_signal): Rename from sigchld_handler. * atimer.c (handle_alarm_signal): * data.c (handle_arith_signal): * dispnew.c (handle_window_change_signal): * emacs.c (handle_fatal_signal, handle_danger_signal): * keyboard.c (handle_input_available_signal): * keyboard.c (handle_user_signal, handle_interrupt_signal): * process.c (handle_pipe_signal, handle_child_signal): New functions, with the actual signal-handling code taken from the original respective signal handlers, sans the sporadic attempts to preserve errno, since that's now done by handle_on_main_thread. * atimer.c (alarm_signal_handler): Remove unnecessary decl. * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft. * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Move to sysdep.c. (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Move initialization of main_thread to sysdep.c's init_signals. * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for our usage, and simplifies the mainline code. (record_child_status_change): New static function, as a helper for handle_child_signal, and with most of the old child handler's contents. (CAN_HANDLE_MULTIPLE_CHILDREN): New constant. (handle_child_signal): Use the above. * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Moved here from emacs.c. (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it; code moved here from emacs.c's main function. * sysdep.c, syssignal.h (handle_on_main_thread): New function, replacing the old SIGNAL_THREAD_CHECK. All uses changed. This lets callers save and restore errno properly. 2012-09-05 Dmitry Antipov Remove redundant or unused things here and there. * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove. * conf_post.h (RE_TRANSLATE): Use char_table_translate. * editfns.c (Fcompare_buffer_substrings): Likewise. * frame.h (struct terminal, struct font_driver_list): Remove redundant declarations. * window.h (Qleft, Qright): Likewise. 2012-09-05 Dmitry Antipov Do not mark objects from deleted buffers, windows and frames. * alloc.c (mark_buffer): Mark just the buffer if it is dead. (mark_object): Likewise for windows and frames. 2012-09-05 Dmitry Antipov * alloc.c (valid_lisp_object_p): Treat killed buffers, buffer_defaults and buffer_local_symbols as valid objects. Return special value to denote them. 2012-09-05 Paul Eggert * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean. * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name) (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file) (file_name_absolute_p, Fsubstitute_in_file_name): (check_executable, check_writable, Ffile_accessible_directory_p) (Fset_file_selinux_context, Fdefault_file_modes) (Finsert_file_contents, choose_write_coding_system) (Fwrite_region, build_annotations, a_write, e_write) (Fdo_auto_save): * filelock.c (boot_time_initialized, get_boot_time) (get_boot_time_1, lock_file_1, within_one_second): * floatfns.c (in_float): * fns.c (concat, internal_equal, Frequire, base64_encode_1) (base64_decode_1, cmpfn_eql, cmpfn_user_defined) (sweep_weak_table, sweep_weak_hash_tables, secure_hash): * lisp.h (struct Lisp_Hash_Table.cmpfn): * window.c (compare_window_configurations): Use bool for booleans. * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits) (Fdefault_file_modes): Now mode_t, not int, for modes. (Fdo_auto_save): Set a boolean to 1 rather than using ++. (internal_delete_file): Now returns void, not a (boolean) int, since nobody was looking at the return value. * lisp.h, window.h: Adjust to above API changes. * xdisp.c (set_message): Simplify and reindent last change. 2012-09-05 Juanma Barranquero * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies. 2012-09-04 Lars Ingebrigtsen * eval.c (call_debugger): Make the function non-static so that we can call it from set_message. * xdisp.c (set_message): Implement the new variable `debug-on-message'. (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'. 2012-09-04 Paul Eggert Give more-useful info on a fatal error (Bug#12328). * alloc.c [ENABLE_CHECKING]: Do not include . (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead of doing the work ourselves. * emacs.c (fatal_error_signal): Let fatal_error_backtrace do most of the work. (fatal_error_backtrace): New function, taken from the guts of the old fatal_error_signal, but with a new option to output a backtrace. (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful info about the signal than just its number. * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls. * sysdep.c: Include (emacs_backtrace): New function, taken partly from the previous code of the 'die' function. (emacs_abort): Call fatal_error_backtrace rather than abort. 2012-09-04 Stefan Monnier * lread.c (readevalloop): Call internal-macroexpand-for-load to perform eager (load-time) macro-expansion. * lisp.mk (lisp): Add macroexp. 2012-09-04 Paul Eggert Simplify redefinition of 'abort' (Bug#12316). Do not try to redefine the 'abort' function. Instead, redo the code so that it calls 'emacs_abort' rather than 'abort'. This removes the need for the NO_ABORT configure-time macro and makes it easier to change the abort code to do a backtrace. * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort. * emacs.c (abort) [!DOS_NT && !NO_ABORT]: Remove; sysdep.c's emacs_abort now takes its place. * lisp.h (emacs_abort): New decl. All calls from Emacs code to 'abort' changed to use 'emacs_abort'. * msdos.c (dos_abort) [defined abort]: Remove; not used. (abort) [!defined abort]: Rename to ... (emacs_abort): ... new name. * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking the place of the old 'abort' in emacs.c. * w32.c, w32fns.c (abort): Do not #undef. * w32.c (emacs_abort): Rename from w32_abort. 2012-09-04 Eli Zaretskii * w32uniscribe.c (uniscribe_shape): Reverse the sign of offsets[j].dv, since the y axis of the screen coordinates points down, while the y axis of the font definition coordinates points up. This fixes display of Arabic diacritics such as KASRA and KASRATAN. (Bug#11860) 2012-09-04 Paul Eggert Be more systematic about _setjmp vs setjmp. * alloc.c (test_setjmp, mark_stack): * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]: (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]: (png_load, my_error_exit, jpeg_load): * process.c (send_process_trap, send_process): Uniformly prefer _setjmp and _longjmp to setjmp and longjmp. The underscored versions are up to 30x faster on some hosts. Formerly, the code used setjmp+longjmp sometimes and _setjmp+_longjmp at other times, with no particular reason to prefer setjmp+longjmp. 2012-09-03 Paul Eggert Fix minor problem found by static checking. * buffer.c (Fdelete_all_overlays): Return nil. 2012-09-03 Martin Rudalics * buffer.c (Fdelete_all_overlays): New function. 2012-09-03 Chong Yidong * gtkutil.c: Add extern decl for Qxft. 2012-09-02 Paul Eggert * emacs.c, eval.c: Use bool for boolean. * emacs.c (initialized, inhibit_window_system, running_asynch_code): (malloc_using_checking) [DOUG_LEA_MALLOC]: (display_arg) [HAVE_X_WINDOWS || HAVE_NS]: (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch) (main, decode_env_path, Fdaemon_initialized): * eval.c (call_debugger, Finteractive_p, interactive_p): (unwind_to_catch, Fsignal, wants_debugger, skip_debugger) (maybe_call_debugger, Fbacktrace): * process.c (read_process_output, exec_sentinel): Use bool for booleans. * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X. All callers changed. * eval.c (interactive_p): Omit always-true boolean argument EXCLUDE_SUBRS_P. All callers changed. * dispextern.h, lisp.h: Reflect above API changes. * firstfile.c (dummy): Use the address of 'main', whose signature won't change, instead of the address of 'initialize', whose signature just changed from int to bool. * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ... * msdos.c (fatal_error_in_progress): ... from here. * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead of incrementing it. (redisplay_internal, unwind_redisplay): Simply clear REDISPLAYING_P when unwinding, instead of saving its previous, always-false value and then restoring it. Clean up some extern decls. Mostly, this hoists extern decls out of .c files and into .h files. That way, we're more likely to catch errors if the interfaces change. * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not declare xg_mark_data. * dispextern.h (x_frame_parm_handlers): * font.h (Qxft): * lisp.h (Qlexical_binding, Qinternal_interpreter_environment) (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold) (Qultra_bold, Qoblique, Qitalic): Move extern decl here from .c file. * alloc.c (xg_mark_data) [USE_GTK]: * doc.c (Qclosure): * eval.c (Qlexical_binding): * fns.c (time) [!HAVE_UNISTD_H]: * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light) (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic): * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]: * lread.c (Qinternal_interpreter_environment): * minibuf.c (Qbuffer): * process.c (QCfamily, QCfilter): * widget.c (free_frame_faces): * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]: * xfont.c (x_clear_errors): * xterm.c (x_frame_parm_handlers): Remove now-redundant extern decls. * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]: * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic): Now static. * xfaces.c: Remove unnecessary static decls. * xterm.c (updating_frame): Remove decl of nonexistent object. * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS) when building globals.h, as the objects that are not built on this host are not needed to compile C files on this host. 2012-09-02 Jan Djärv * gtkutil.h: Remove prototype for x_wm_set_size_hint. * frame.h: Add missing prototype for x_wm_set_size_hint. 2012-09-02 Paul Eggert * doc.c, editfns.c, insdel.c, intervals.c: Use bool for boolean. * doc.c (read_bytecode_char, get_doc_string, reread_doc_file) (Fdocumentation, Fdocumentation_property, Fsnarf_documentation) (Fsubstitute_command_keys): * editfns.c (region_limit, find_field, Fconstrain_to_field) (save_excursion_save, save_excursion_restore) (disassemble_lisp_time, decode_time_components, emacs_nmemftime) (format_time_string, general_insert_function) (make_buffer_string, make_buffer_string_both) (Fsubst_char_in_region, Ftranslate_region_internal, Fformat): * insdel.c (check_markers, gap_left, adjust_markers_for_insert) (copy_text, insert_1, insert_1_both, insert_from_string) (insert_from_string_before_markers, insert_from_string_1) (insert_from_buffer, insert_from_buffer_1, replace_range) (replace_range_2, del_range_1, del_range_byte, del_range_both) (del_range_2, modify_region): * intervals.c (intervals_equal, balance_possible_root_interval) (adjust_intervals_for_insertion, merge_properties_sticky) (graft_intervals_into_buffer, lookup_char_property) (adjust_for_invis_intang, set_point_both) (get_property_and_range, compare_string_intervals) (set_intervals_multibyte_1, set_intervals_multibyte): * keyboard.c (decode_timer): Use bool for boolean. * intervals.h, lisp.h, systime.h: Reflect above API changes. * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans. 2012-09-02 Chong Yidong * keymap.c (push_key_description): Print M-TAB as C-M-i (Bug#11758). 2012-09-02 Juanma Barranquero * makefile.w32-in (CCL_H, W32FONT_H): New macros.

(Bug#11860) * image.c: Restore mistakenly removed inclusion of w32.h. Without it, GCC doesn't see prototypes of w32_delayed_load, and complains about implicit conversions from integer to pointer. 2012-09-01 Daniel Colascione * w32fns.c (x_display_info_for_name): Prevent crash if w32 window system used too early. 2012-09-01 Paul Eggert Better seed support for (random). * emacs.c (main): Call init_random. * fns.c (Frandom): Set the seed from a string argument, if given. Remove long-obsolete Gentzel cruft. * lisp.h, sysdep.c (seed_random): Now takes address and size, not long. (init_random): New function. 2012-09-01 Daniel Colascione * xterm.h: Add header guards.

(Bug#12302) 2012-08-28 Jan Djärv * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize button_values to NULL. Call setStykeMask so dialogs get a close button. (windowShouldClose:): Set window_closed. (dealloc): New member, free button_values. (process_dialog:): Make member function. Remove window argument, replace window with self. Count buttons and allocate and store values in button_values. (addButton:value:row:): value is int with the name tag. Call setTag with tag. Remove return self, declare return value as void.

(Fother_buffer, other_buffer_safely): Remove redundant nested declaration. 2012-08-28 Dmitry Antipov Always use set_buffer_if_live to restore original buffer at unwind. * buffer.h (record_unwind_current_buffer): New function. * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c: * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c: * undo.c, window.c: Adjust users. * buffer.c (set_buffer_if_live): Fix comment. 2012-08-28 Dmitry Antipov Fix usage of set_buffer_internal. * buffer.h (set_buffer_internal): Make it BUFFER_INLINE. * buffer.c (set_buffer_if_live): Use set_buffer_internal. * coding.c (decode_coding): Omit redundant test. * fileio.c (decide_coding_unwind): Likewise. * fns.c (secure_hash): Likewise. * insdel.c (modify_region): Likewise. * keyboard.c (command_loop_1): Likewise. * print.c (PRINTFINISH): Likewise. * xdisp.c (run_window_scroll_functions): Use set_buffer_internal. 2012-08-27 Paul Eggert * dispnew.c: Use bool for boolean. (frame_garbaged, display_completed, delayed_size_change) (fonts_changed_p, add_window_display_history) (add_frame_display_history, verify_row_hash) (adjust_glyph_matrix, clear_window_matrices, glyph_row_slice_p) (row_equal_p, realloc_glyph_pool) (allocate_matrices_for_frame_redisplay) (showing_window_margins_p) (adjust_frame_glyphs_for_frame_redisplay) (build_frame_matrix_from_leaf_window, make_current) (mirrored_line_dance, mirror_line_dance, update_frame) (update_window_tree, update_single_window) (check_current_matrix_flags, update_window, update_text_area) (update_window_line, set_window_update_flags, scrolling_window) (update_frame_1, scrolling, buffer_posn_from_coords) (do_pending_window_change, change_frame_size) (change_frame_size_1, sit_for): Use bool for boolean. (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows, and remove last int (actually boolean) argument, which was always 0. All callers changed. * dispextern.h, frame.h, lisp.h: Reflect above API changes. * dispextern.h (struct composition_it): Use bool for boolean. (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'. (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf. * dired.c (file_name_completion): Use bool for boolean. (This was missed in an earlier change.) 2012-08-27 Martin Rudalics * window.c (Fset_window_configuration): Revert first part of last change. 2012-08-27 Jan Djärv * nsterm.h (NSPanel): New class variable dialog_return. * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize dialog_return. (windowShouldClose:): Use stop instead of stopModalWithCode. (clicked:): Ditto, and also set dialog_return (Bug#12258). (timeout_handler:): Use stop instead of abortModal. Send a dummy event. (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when modal loop returns. 2012-08-27 Paul Eggert * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans. * composite.c (find_composition, composition_gstring_p) (composition_reseat_it, find_automatic_composition): * data.c (let_shadows_buffer_binding_p) (let_shadows_global_binding_p, set_internal, make_blv) (Fmake_variable_buffer_local, Fmake_local_variable) (Fmake_variable_frame_local, arithcompare, cons_to_unsigned) (cons_to_signed, arith_driver): * dbusbind.c (xd_in_read_queued_messages): * dired.c (directory_files_internal, file_name_completion): Use bool for booleans. * dired.c (file_name_completion): * process.h (fd_callback): Omit int (actually boolean) argument.

(detect_coding): Use unsigned, not signed, to copy an unsigned field. (decode_coding, encode_coding, decode_coding_gap): Return 'void', not a boolean 'int', since callers never look at the return value. (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'. * coding.h (decoding_buffer_size, encoding_buffer_size) (emacs_mule_string_char): Remove unused extern decls. (struct iso_2022_spec, struct coding_system): Use 'unsigned int : 1' for boolean fields, since there's more than one. (struct emacs_mule_spec): Remove unused field 'full_support'. All initializations removed. * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'. 2012-08-27 Dmitry Antipov Fix spare memory change (Bug#12286). * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE. (valid_lisp_object_p): Likewise. 2012-08-27 Martin Rudalics * window.c (Fset_window_configuration): Record any window's old buffer if it's replaced (see Bug#8789). If the new current buffer doesn't appear in the selected window, go to its old point (Bug#12208). 2012-08-27 Dmitry Antipov Special MEM_TYPE_SPARE to denote reserved memory. * alloc.c (enum mem_type): New memory type. (refill_memory_reserve): Use new type for spare memory. This prevents live_cons_p and live_string_p from incorrect detection of uninitialized objects from spare memory as live. 2012-08-26 Paul Eggert Spelling fixes. * Makefile.in (.PHONY): versioclean -> versionclean. Remove unused external symbols. * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector): * window.c (Qwindow_valid_p, decode_valid_window): Now static, not extern. * data.c (Qinterval): Remove; unused.

All callers changed. * character.h, charset.h: Adjust to match previous changes. * character.h (char_printable_p): Remove decl of nonexistent function. * charset.h (struct charset): Members code_linear_p, iso_chars_96, ascii_compatible_p, supplementary_p, compact_codes_p, unified_p are all boolean, so make them single-bit bitfields. * lisp.h (ASET): Remove attempt to detect side effects. It was meant to be temporary and it often doesn't work, because when IDX has side effects the behavior of IDX==IDX is undefined. See Stefan Monnier in . 2012-08-26 Barry O'Reilly * lisp.h (functionp): New function (extracted from Ffunctionp). (FUNCTIONP): Use it. * eval.c (Ffunctionp): Use it. 2012-08-25 Paul Eggert * xgselect.c (xg_select): Use auto storage for the GPollFD buffer as that's faster and simpler than static storage. Don't bother with the g_main_context_query overhead if g_main_context_pending says no events are pending. (gfds, gfds_size): Remove these static vars. (xgselect_initialize): Remove; no longer needed. All uses and decls removed. * emacs.c (fatal_error_signal_hook): Remove. All uses removed.

(LIBES): Use it. * bytecode.c, callint.c, callproc.c: Use bool for boolean. * bytecode.c (exec_byte_code): * callint.c (check_mark, Fcall_interactively): * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1) (getenv_internal, sync_process_alive, call_process_exited): * lisp.h (USE_SAFE_ALLOCA): Use bool for booleans, instead of int. * lisp.h, process.h: Adjust prototypes to match above changes. * callint.c (Fcall_interactively): Don't assume the mark's offset fits in 'int'. 2012-08-24 Paul Eggert * buffer.c, buffer.h: Use bool for boolean. * buffer.c (reset_buffer_local_variables) (buffer_lisp_local_variables, Fset_buffer_modified_p) (Frestore_buffer_modified_p, Fset_buffer_multibyte): (overlays_at, overlays_in, mouse_face_overlay_overlaps) (overlay_touches_p, overlay_strings, Foverlay_put) (report_overlay_modification, call_overlay_mod_hooks): (mmap_enlarge, mmap_set_vars): * buffer.h (buffer_has_overlays, uppercasep, lowercasep): Use bool for booleans, instead of int. * buffer.c (compact_buffer, mmap_free_1): Return void, not int, since the 1-or-0 return value is always ignored anyway. (mmap_initialized_p): * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int. * buffer.h, lisp.h: Adjust prototypes to match above changes. 2012-08-23 Paul Eggert * bidi.c: Use bool for boolean. This is a bit more readable, and makes the text segment of bidi.o 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15). Presumably it's faster too. (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level): Now bool. (bidi_cache_find_level_change, bidi_cache_iterator_state) (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes) (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init) (bidi_explicit_dir_char, bidi_level_of_next_char) (bidi_find_other_level_edge, bidi_move_to_visually_next): Use bool for booleans, instead of int. * dispextern.h (bidi_init_it, bidi_paragraph_init) (bidi_unshelve_cache): Adjust decls to match code. 2012-08-23 Martin Rudalics * keyboard.c (Fposn_at_x_y): Do not allow internal window as argument. 2012-08-23 Paul Eggert * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean. * atimer.h: Include . 2012-08-22 Dan Nicolaescu * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to compile time tests instead of run time tests on systems that do not use them. (FRAME_MAC_P): Remove leftover from deleted code. * frame.c (syms_of_frame): Remove leftover from deleted code. 2012-08-22 Jan Djärv * nsterm.m (insertText:): Don't clear modifiers if code is space. 2012-08-22 Paul Eggert * fontset.c (FONTSET_ADD): Return void, not Lisp_Object. Otherwise, the compiler complains about (A?B:C) where B is void and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12. (fontset_add): Return void, for FONTSET_ADD. 2012-08-21 Paul Eggert * alloc.c: Use bool for booleans. (gc_in_progress, abort_on_gc) (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]: (dont_register_blocks) [GC_MALLOC_CHECK]: (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

(test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]: Remove unused local. * alloc.c (PURE_POINTER_P): * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean. * editfns.c (Fformat): * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name) (Fdo_auto_save): * fns.c (sweep_weak_table): * lisp.h (suppress_checking, push_message, survives_gc_p) (make_pure_string, gc_in_progress, abort_on_gc): * lread.c (readchar, read1): * print.c (Fprin1_to_string): * xdisp.c (push_message): Use bool for booleans affected directly or indirectly by alloc.c's changes. Make recently-introduced setters macros. * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii) (set_fontset_base, set_fontset_frame, set_fontset_nofont_face) (set_fontset_default, set_fontset_fallback): Rename from their upper-case counterparts, and make them functions rather than macros. This is more consistent with the other recently-introduced setters. These don't need to be inline, since they're local. 2012-08-21 Jan Djärv * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in the loop (Bug#12247). 2012-08-21 Paul Eggert * lisp.h (vcopy): Use memcpy rather than our own loop. This fixes a performance regression introduced by the recent addition of vcopy. This means 'vcopy' will need to be modified for a copying collector, but that's OK. Also, tighten the checking in the assertion. 2012-08-21 Eli Zaretskii * w32uniscribe.c (uniscribe_shape): Fix producing gstring components for RTL text (Bug#11860). Adjust X-OFFSET of each non-base glyph for the width of the base character, according to what x_draw_composite_glyph_string_foreground expects.

(set_marker_both, set_marker_restricted_both): Use live_buffer. 2012-07-22 Paul Eggert * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int, as it's limited by the amount of memory, not by INT_MAX. 2012-07-21 Eli Zaretskii * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore' in special-event-map. See the discussion at https://lists.gnu.org/r/emacs-devel/2012-06/msg00417.html for the reasons. * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning info.dwItemData.

Use dtoastr, not snprintf. * process.c (Fmake_network_process): Diagnose service names that are too long, rather than silently truncating them or creating non-null-terminated names. (Fnetwork_interface_info): Likewise, for interface names. * sysdep.c (system_process_attributes) [GNU_LINUX]: Prefer sprintf to strncat. * xdisp.c (debug_method_add) [GLYPH_DEBUG]: Prefer vsnprintf to vsprintf + strncpy. 2012-07-10 Glenn Morris * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]: Clarify fallback case. 2012-07-10 Dmitry Antipov Use XCAR and XCDR instead of Fcar and Fcdr where possible. * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c, * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c, * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR where argument type is known to be a Lisp_Cons. 2012-07-10 Tom Tromey * bytecode.c (BYTE_CODE_THREADED): New macro. (BYTE_CODES): New macro. Replaces all old byte-code defines. (enum byte_code_op): New type. (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros. (exec_byte_code): Use them. Use token threading when applicable. 2012-07-10 Dmitry Antipov Optimize pure C strings initialization. * lisp.h (make_pure_string): Fix prototype. (build_pure_c_string): New function, defined as static inline. This provides a better opportunity to optimize away calls to strlen when the function is called with compile-time constant argument. * alloc.c (make_pure_c_string): Fix comment. Change to add nchars argument, adjust users accordingly. Use build_pure_c_string where appropriate. * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c, * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c, * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate. 2012-07-10 Dmitry Antipov Avoid calls to strlen in miscellaneous functions. * buffer.c (init_buffer): Use precalculated len, adjust if needed. * font.c (Ffont_xlfd_name): Likewise. Change to call make_string. * lread.c (openp): Likewise. 2012-07-10 Dmitry Antipov Avoid calls to strlen in path processing functions. * fileio.c (file_name_as_directory): Add comment. Change to add srclen argument and return the length of result. Adjust users accordingly. (directory_file_name): Fix comment.

Adjust users accordingly. * filelock.c (fill_in_lock_file_name): Avoid calls to strlen. 2012-07-10 Glenn Morris * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h: Move PENDING_OUTPUT_COUNT definition to configure. * s/irix6-5.h (DATA_START, DATA_SEG_BITS): * s/hpux10-20.h (DATA_SEG_BITS, DATA_START): * s/gnu.h (DATA_START): Move definitions to configure. * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards. We include usg5-4-common.h, which defines them both. * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses O_RDONLY already includes it). Stop ns builds setting the EMACSLOADPATH environment variable. * nsterm.m (ns_load_path): Rename from ns_init_paths. Now it does not set EMACSLOADPATH, just returns the load-path string. * nsterm.h: Update accordingly. * lread.c [HAVE_NS]: Include nsterm.h. (init_lread) [HAVE_NS]: Use ns_load_path. * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths. 2012-07-09 Glenn Morris * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here, since the included bsd-common.h does so. Stop ns builds setting the EMACSPATH environment variable. * nsterm.m (ns_exec_path): New function, split from ns_init_paths. (ns_init_paths): Do not set EMACSPATH. * nsterm.h (ns_exec_path): Add it. * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_exec_path. * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return. 2012-07-09 Paul Eggert * process.c (wait_reading_process_output): 'waitchannels' was unset when read_kbd || !NILP (wait_for_cell); fix this. Add GCC-style 'const' attribute to functions that can use it. * character.h (char_resolve_modifier_mask): * keyboard.h (make_ctrl_char): * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe) (init_character_once, next_almost_prime, init_fns, init_image) (flush_pending_output, init_sound): * mem-limits.h (start_of_data): * menu.h (finish_menu_items): Add ATTRIBUTE_CONST. * emacs.c (DEFINE_DUMMY_FUNCTION): Declare the dummy function with ATTRIBUTE_CONST. * lisp.h (Fbyteorder, Fmax_char, Fidentity): Add decls with ATTRIBUTE_CONST. Minor improvements to make_formatted_string. * alloc.c (make_formatted_string): Prefer int to ptrdiff_t where int is good enough, as vsprintf returns an int. * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF. 2012-07-09 Dmitry Antipov Use make_formatted_string to avoid double length calculation. * lisp.h (make_formatted_string): New prototype. * alloc.c (make_formatted_string): New function. * buffer.c (Fgenerate_new_buffer_name): Use it. * dbusbind.c (syms_of_dbusbind): Likewise. * editfns.c (Fcurrent_time_zone): Likewise. * filelock.c (get_boot_time): Likewise. * frame.c (make_terminal_frame, set_term_frame_name) (x_report_frame_params): Likewise. * image.c (gs_load): Likewise. * minibuf.c (get_minibuffer): Likewise. * msdos.c (dos_set_window_size): Likewise. * process.c (make_process): Likewise. * xdisp.c (ensure_echo_area_buffers): Likewise. * xsettings.c (apply_xft_settings): Likewise. 2012-07-09 Glenn Morris Stop ns builds polluting the environment with EMACSDATA, EMACSDOC. * nsterm.m (ns_etc_directory): New function, split from ns_init_paths. (ns_init_paths): Do not set EMACSDATA, EMACSDOC. * nsterm.h (ns_etc_directory): Add it. * callproc.c [HAVE_NS]: Include nsterm.h. (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory. 2012-07-09 Dmitry Antipov Move marker debugging code under MARKER_DEBUG. * marker.c (MARKER_DEBUG): Move marker debugging code under #ifdef MARKER_DEBUG because byte_char_debug_check is too slow for bootstrap with --enable-checking (~3x slowdown reported by Juanma Barranquero ). (verify_bytepos): Move under #ifdef MARKER_DEBUG. 2012-07-08 Paul Eggert * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t. See . 2012-07-08 Eli Zaretskii * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph has no font, use the frame's font.

(Fx_parse_geometry) [HAVE_NS]: Don't return garbage. (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label. * image.c (x_create_bitmap_from_file) [HAVE_NS]: (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]: * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal): * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]: Fix pointer signedness problem. * xfaces.c (FRAME_X_FONT_TABLE): * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros. 2012-07-07 Glenn Morris * lread.c (load_path_check): New function, split from init_lread. (init_lread): Reorganize. Motivation: If EMACSLOADPATH is set, check/warn about that rather than the defaults, which we are not going to use. Hence we can remove the turn_off_warning and WINDOWSNT || HAVE_NS tests. Don't warn if site-lisp directories are missing. If not installed, start from a blank load-path, since PATH_LOADSEARCH refers to the eventual installation directories. 2012-07-07 Eli Zaretskii Support truncation and continuation glyphs on GUI frames, when fringes are disabled. (Bug#11832) * xdisp.c (init_iterator): Get dimensions of truncation and continuation glyphs even if on GUI frames. Adjust it->last_visible_x on GUI frames when the left or right fringes, or both, are absent. (start_display, move_it_in_display_line_to): Handle the case of a GUI frame without a fringe to display continuation or truncation glyphs. (insert_left_trunc_glyphs): Support GUI frames: make sure truncation glyphs overwrite enough glyphs from the current line to have sufficient space in pixels. (display_line): Support truncation and continuation glyphs on GUI frames. If some spare pixels are left on the line after inserting the truncation glyphs, fill that space with a stretch glyph of a suitably computed width. * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not produce_glyphs, to support GUI sessions. 2012-07-07 Paul Eggert * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781). * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797). Do not require float-time's arg to fit in time_t (Bug#11825). This works better on hosts where time_t is unsigned, and where float-time is applied to the (negative) difference between two times. * editfns.c (decode_time_components): Last arg is now double *, not int *, and means to store all the result as a double, without worrying about whether the seconds part fits in time_t. All callers changed. (lisp_time_argument): Remove last int * arg, as it's no longer needed. All callers changed. (Ffloat_time): Do not fail merely because the specified time falls outside of time_t range. 2012-07-07 Glenn Morris * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV): * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM): * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively). 2012-07-07 Juanma Barranquero * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)): Update dependencies. * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp. 2012-07-06 Paul Eggert Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786). * dispextern.h, nsfns.m, nsterm.m: Include . * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp. * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp. * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp. * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove. * xfont.c (compare_font_names): Redo to omit the need for casts. 2012-07-06 Andreas Schwab * xfns.c (Fx_change_window_property): Doc fix. * w32fns.c (Fx_change_window_property): Doc fix. * w32fns.c (Fx_window_property): Accept the same arguments as the X Windows version. Doc fix. * xfns.c (Fx_window_property): Doc fix. (Bug#11870) 2012-07-06 Juanma Barranquero Eli Zaretskii * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt. Windows-specific code from nt/config.nt moved here. Obsolete settings removed. 2012-07-06 Paul Eggert * process.c: Avoid unnecessary calls to gettime. (wait_reading_process_output): Don't get the time of day when gobbling data immediately and not waiting, as there's no need for it in that case. This removes a FIXME. 2012-07-06 Jan Djärv * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3 is defined (Bug#11768). 2012-07-06 Dmitry Antipov Fix marker debugging code. * marker.c (byte_char_debug_check): Do not perform the check if buffer is not multibyte. (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Call byte_char_debug_check with correct arguments. 2012-07-06 Dmitry Antipov Compile marker debugging code only if ENABLE_CHECKING is defined. * marker.c (byte_char_debug_check, count_markers): Use only if ENABLE_CHECKING is defined. (byte_debug_flag): Remove. (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos): Always call byte_char_debug_check if ENABLE_CHECKING is defined. 2012-07-06 Dmitry Antipov Avoid code repetition in marker-related functions. * marker.c (attach_marker): New function. (Fset_marker, set_marker_restricted, set_marker_both) (set_marker_restricted_both): Use it. (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at): Consistently rename charno to charpos. (marker_position): Add eassert. (marker_byte_position): Convert to eassert. 2012-07-06 Dmitry Antipov Simplify list operations in unchain_overlay and unchain_marker. * buffer.c (unchain_overlay): Simplify. Add comment. * marker.c (unchain_marker): Simplify. Fix comments. 2012-07-06 Dmitry Antipov Introduce fast path for the widely used marker operation. * alloc.c (build_marker): New function. * lisp.h (build_marker): New prototype. * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it. * composite.c (autocmp_chars): Likewise. * editfns.c (buildmark): Remove.

(delete_all_overlays, Fdelete_overlay): Use it. * minibuf.c (get_minibuffer): Fix comment. 2012-07-06 Paul Eggert Port to OpenBSD 5.1 amd64. * sysdep.c [BSD_SYSTEM]: Include before . This is needed for OpenBSD, and should be harmless on all BSD systems. Also, include , as it should be available on all BSD_SYSTEM hosts given that we're already calling sysctl in that case. (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but use p_pid member, not kp_proc.pid. 2012-07-06 Glenn Morris * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows. 2012-07-05 Paul Eggert More xmalloc and related cleanup. * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c: * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c: * font.c, fontset.c, frame.c, fringe.c, ftfont.c, ftxfont.c, gmalloc.c: * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c: * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c: * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c: * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c: * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c: * xterm.c: Omit needless casts involving void * pointers and allocation. Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))", as the former is more robust if P's type is changed. Prefer xzalloc to xmalloc + memset 0. Simplify malloc-or-realloc to realloc. Don't worry about xmalloc returning a null pointer. Prefer xstrdup to xmalloc + strcpy. * editfns.c (Fmessage_box): Grow message_text by at least 80 when growing it. * keyboard.c (apply_modifiers_uncached): Prefer local array to alloca of a constant. 2012-07-05 Eli Zaretskii * xdisp.c (display_line): Fix horizontal pixel coordinates when hscroll is larger than the line width. Fixes long and futile looping inside extend_face_to_end_of_line (on a TTY) producing glyphs that are not needed and thrown away. 2012-07-05 Dmitry Antipov * marker.c (set_marker_restricted_both): Simplify by using clip_to_bounds. 2012-07-05 Paul Eggert * editfns.c (region_limit): Simplify by using clip_to_bounds. 2012-07-05 Jan Djärv * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is not defined (Bug#11768).

(xg_initialize): Get settings by calling gtk_settings_get_for_screen with default display (Bug#11768). 2012-07-05 Eli Zaretskii * xdisp.c (window_hscroll_limited): New function. (pos_visible_p, init_iterator): Use it to avoid overflow of pixel coordinates when window's hscroll is set to insanely large values. (Bug#11857) 2012-07-05 Juanma Barranquero * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo. ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies. 2012-07-05 Dmitry Antipov Cleanup xmalloc. * lisp.h (xzalloc): New prototype. Omit needless casts. * alloc.c (xzalloc): New function. Omit needless casts. * charset.c: Omit needless casts. Convert all calls to xmalloc with following memset to xzalloc. * dispnew.c: Likewise. * fringe.c: Likewise. * image.c: Likewise. * sound.c: Likewise. * term.c: Likewise. * w32fns.c: Likewise. * w32font.c: Likewise. * w32term.c: Likewise. * xfaces.c: Likewise. * xfns.c: Likewise. * xterm.c: Likewise. * atimer.c: Omit needless casts. * buffer.c: Likewise. * callproc.c: Likewise. * ccl.c: Likewise. * coding.c: Likewise. * composite.c: Likewise. * doc.c: Likewise. * doprnt.c: Likewise. * editfns.c: Likewise. * emacs.c: Likewise. * eval.c: Likewise. * filelock.c: Likewise. * fns.c: Likewise. * gtkutil.c: Likewise. * keyboard.c: Likewise. * lisp.h: Likewise. * lread.c: Likewise. * minibuf.c: Likewise. * msdos.c: Likewise. * print.c: Likewise. * process.c: Likewise. * region-cache.c: Likewise. * search.c: Likewise. * sysdep.c: Likewise. * termcap.c: Likewise. * terminal.c: Likewise. * tparam.c: Likewise. * w16select.c: Likewise. * w32.c: Likewise. * w32reg.c: Likewise. * w32select.c: Likewise. * w32uniscribe.c: Likewise. * widget.c: Likewise. * xdisp.c: Likewise. * xmenu.c: Likewise. * xrdb.c: Likewise. * xselect.c: Likewise. 2012-07-05 Paul Eggert * fileio.c (time_error_value): Check the right error number. Problem reported by Troels Nielsen in . 2012-07-04 Paul Eggert * window.c (set_window_hscroll): Revert the 100000 hscroll limit. This should be fixed in a better way; see Eli Zaretskii in . (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll. * fileio.c (time_error_value): Rename from special_mtime. The old name's problems were noted by Eli Zaretskii in . * emacs.c (gdb_pvec_type): Change it back to enum pvec_type. This variable's comment says Emacs needs at least one GDB-visible symbol of type enum pvec_type, to work around GDB problems. The symbol's value doesn't matter. * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';' that causes compilation to fail on pre-C99 compilers. 2012-07-04 Juanma Barranquero * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY) (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete. 2012-07-04 Dmitry Antipov * buffer.c (init_buffer_once): Fix initialization of headers for buffer_defaults and buffer_local_symbols.

Use switch. 2012-07-04 Paul Eggert * doprnt.c (doprnt): Don't assume string length fits in 'int'. Tighten new eassert a bit. 2012-07-04 Dmitry Antipov Fix compilation with --enable-gcc-warnings and -O1 optimization level. * doprnt.c (doprnt): Change type of tem to int, initialize to avoid compiler warning. Add eassert. * search.c (simple_search): Initialize match_byte to avoid compiler warning. Add eassert. 2012-07-04 Paul Eggert Avoid weird behavior with large horizontal scrolls. Without this change, for example, large hscroll values would mess up Emacs's display on Fedora 15 x86, presumably due to overflows in int calculations in the display code. Also, if buffers had long lines, Emacs would freeze. * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB. (set_window_hscroll): New function, containing the old guts of Fset_window_hscroll. Return the clipped value. (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it. This avoids the need to check against PTRDIFF_MAX. * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch. 2012-07-04 Dmitry Antipov * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch. 2012-07-04 Paul Eggert * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207) Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later, since GCC 4.4.6 issues a bogus warning for them. Fix bugs in file timestamp newness comparisons. * fileio.c (Ffile_newer_than_file_p): * lread.c (Fload): Use full timestamp resolution of files, not just the 1-second resolution, so that files that are only slightly newer still count as newer. * fileio.c (Ffile_newer_than_file_p): Don't assume file timestamps fit in 'int'; this fixes a Y2038 bug on most hosts. 2012-07-03 Paul Eggert * fileio.c: Improve handling of file time marker. (Bug#11852) (special_mtime): New function. (Finsert_file_contents, Fverify_visited_file_modtime): Use it to set special mtime values consistently. 2012-07-03 Andreas Schwab * fileio.c (Finsert_file_contents): Properly handle st_mtime marker for non-existing file. (Bug#11852) 2012-07-03 Glenn Morris * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN and did not make it into globals.h). 2012-07-03 Tom Tromey * window.c (Fset_window_margins, Fset_window_fringes) (Fset_window_scroll_bars, Fset_window_vscroll): No longer static. * textprop.c (Fprevious_property_change): No longer static. * syntax.c (Fsyntax_table_p): No longer static. * process.c (Fget_process, Fprocess_datagram_address): No longer static. * keymap.c (Flookup_key, Fcopy_keymap): No longer static. * keyboard.c (Fcommand_execute): No longer static.

(Bug#1229) 2012-07-03 Dmitry Antipov Fix block vector allocation code to allow VECTOR_BLOCK_SIZE values which aren't power of 2. * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users accordingly. 2012-07-03 Stefan Monnier * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better. * alloc.c (mark_object): Revert part of last patch to use `switch'. 2012-07-03 Dmitry Antipov * alloc.c (allocate_vector_block): Remove redundant calls to mallopt if DOUG_LEA_MALLOC is defined. (allocate_vectorlike): If DOUG_LEA_MALLOC is defined, avoid calls to mallopt if zero_vector is returned. 2012-07-03 Dmitry Antipov * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES is enabled, avoid dereferencing NULL current_sblock if running undumped. 2012-07-03 Dmitry Antipov Cleanup basic buffer management. * buffer.h (struct buffer): Change layout to use generic vector marking code. Fix some comments. Change type of 'clip_changed' to bitfield. Remove unused #ifndef old. (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove. (GET_OVERLAYS_AT): Fix indentation. (for_each_per_buffer_object_at): New macro. * buffer.c (clone_per_buffer_values, reset_buffer_local_variables) (Fbuffer_local_variables): Use it. (init_buffer_once, syms_of_buffer): Remove unused #ifndef old. * alloc.c (allocate_buffer): Adjust to match new layout of struct buffer. Fix comment. (mark_overlay): New function. (mark_buffer): Use it. Use mark_vectorlike to mark normal Lisp area of struct buffer. (mark_object): Use it. Adjust marking of misc objects and related comments. 2012-07-02 Paul Eggert * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS" wrapper that is not needed because the wrapped code is a no-op (zero machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined. This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64. 2012-07-02 Dmitry Antipov * alloc.c (mark_buffer): Simplify. Remove prototype. (mark_object): Add comment. Reorganize marking of vector-like objects. Use CHECK_LIVE for all vector-like objects except buffers and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid redundant calls to mark_vectorlike for bool vectors. 2012-06-30 Glenn Morris * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp. * epaths.in (PATH_SITELOADSEARCH): New. * lread.c (init_lread): Use PATH_SITELOADSEARCH. This is rather than relying on --enable-locallisppath elements having "site-lisp" in their names. (Bug#10208#25, 11658) 2012-06-30 Eli Zaretskii * w32proc.c (sys_select): Accept and ignore one more argument. * w32.c (emacs_gnutls_pull): Call select with one more argument. * sysselect.h [DOS_NT]: Don't include sys/select.h. (pselect) [!MS_DOS]: Redirect to sys_select. * sysdep.c: Don't include dos.h and dosfns.h. * process.c (sys_select): * msdos.c (sys_select): Accept one more argument and ignore it. * msdos.c (event_timestamp, sys_select): Use gnulib's gettime; adapt data types and code to that. * dosfns.c: * msdos.c (gettime, settime): Define away the prototypes in dos.h, which clashes with the gnulib function of the same name. 2012-06-30 Andreas Schwab * font.c (font_style_to_value, font_style_symbolic) (font_prop_validate_style): Add type checks for values in font_style_table. * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first argument. * character.c, charset.c, menu.c, process.c, window.c: Adjust all uses. 2012-06-29 Eli Zaretskii * xdisp.c (try_window_id): Undo last change. * w32.c (getwd): Adjust commentary about startup_dir. (init_environment): Always call sys_access, even in non-MSVC builds. Don't chdir to the directory of the Emacs executable. This undoes code from 1997 which was justified by the need to "avoid conflicts when removing and renaming directories". But its downside was that every relative file name was being interpreted relative to the directory of the Emacs executable, which can never be TRT. In particular, it broke sys_access when called with relative file names. (sys_access): Map GetLastError to errno. 2012-06-29 Dmitry Antipov * window.h (struct window): Change type of 'fringes_outside_margins' to bitfield. Fix comment. Adjust users accordingly.

In the old days this wasn't portable, since some sprintf implementations returned char *. But they died out years ago and Emacs already assumes sprintf returns int. Similarly for float_to_string. This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64. * ccl.c (ccl_driver): * character.c (string_escape_byte8): * data.c (Fnumber_to_string): * doprnt.c (doprnt): * print.c (print_object): * xdisp.c (message_dolog): * xfns.c (syms_of_xfns): Use sprintf or float_to_string result to avoid need to call strlen. * data.c (Fnumber_to_string): Use make_unibyte_string, since the string must be ASCII. * lisp.h, print.c (float_to_string): Now returns int length. * term.c (produce_glyphless_glyph): Use sprintf result rather than recomputing it. Clean out last vestiges of the old HAVE_CONFIG_H stuff. * Makefile.in (ALL_CFLAGS): * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H. * gmalloc.c, regex.c: Include unconditionally. 2012-06-25 Dmitry Antipov * dispextern.h (xstrcasecmp): Define to library function strcasecmp if available. * xfaces.c: Do not use xstrcasecmp if strcasecmp is available. 2012-06-25 Andreas Schwab * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence): Avoid comma operator. * menu.c (push_submenu_start, push_submenu_end) (push_left_right_boundary, push_menu_pane): Likewise. * msdos.c (dos_rawgetc): Likewise. 2012-06-25 Dmitry Antipov * xfns.c (xic_create_fontsetname): Remove redundant calls to memset. 2012-06-25 Paul Eggert * gtkutil.c (get_utf8_string): Remove redundant assignment. sprintf already null-terminates its output. * xfns.c (x_window): Remove redundant cast. 2012-06-25 Dmitry Antipov * xmenu.c (xmenu_show, xdialog_show): Explicit cast from `const char *' to `char *' to avoid compiler warning. 2012-06-24 Paul Eggert * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string instead of truncating it to 63 (admittedly a generous limit). * process.c: Fix spelling and caps in comments. 2012-06-24 Dan Nicolaescu * emacs.c (setpgrp): Remove definition, unused. * sysdep.c (setpgrp): Remove definition, not used in this file. 2012-06-24 Juanma Barranquero * makefile.w32-in: Update dependencies. 2012-06-24 Eli Zaretskii * makefile.w32-in (TIMESPEC_H): Remove nt/inc/sys/time.h.

(w32_get_internal_run_time): Remove usused variable `time_100ns'. 2012-06-23 Paul Eggert * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos. Privately reported by Herbert J. Skuhra. (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST. All uses changed.

Privately reported by Herbert J. Skuhra. [__FreeBSD__]: Remove "*/" typo after "#include". (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function. (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro. (TIMEVAL, system_process_attributes) [__FreeBSD__]: Don't assume EMACS_TIME and struct timeval are the same type. 2012-06-22 Paul Eggert Support higher-resolution time stamps (Bug#9000). The time stamps are only nanosecond-resolution at the C level, since that's the best that any real-world system supports now. But they are picosecond-resolution at the Lisp level, as that's easy, and leaves room for future OS improvements. * Makefile.in (LIB_CLOCK_GETTIME): New macro. (LIBES): Use it. * alloc.c (Fgarbage_collect): Port to higher-res time stamps. Don't get current time unless it's needed. * atimer.c: Include unconditionally, since gnulib now provides it if it's absent. (start_atimer): Port to higher-res time stamps. Check for time stamp overflow. Don't get current time more often than is needed. * buffer.h (struct buffer): Buffer modtime now has high resolution. Include systime.h, not time.h.

(Ffile-attributes): File times now have higher resolution. * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h. (struct image): Timestamp now has higher resolution. * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always has at least microseconds now. All uses removed. (update_frame, update_single_window, update_window, update_frame_1) (Fsleep_for, sit_for): Port to higher-resolution time stamps. (duration_to_sec_usec): Remove; no longer needed. * editfns.c (time_overflow): Now extern. (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument) (float-time, Fformat_time_string, Fcurrent_time_string) (Fcurrent_time_zone): Accept and generate higher-resolution time stamps. (make_time_tail, make_lisp_time, dissassemble_lisp_time) (decode_time_components, lisp_seconds_argument): New functions. (make_time): Now static. (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec. Report an error if the time is invalid, rather than having the caller do that. * fileio.c: Include (Fcopy_file): Copy higher-resolution time stamps. Prefer to set the time stamp via a file descriptor if that works. (Fset_file_times, Finsert_file_contents, Fwrite_region) (Fverify_visited_file_modtime, Fclear_visited_file_modtime) (Fvisited_file_modtime, Fset_visited_file_modtime): Support higher-resolution time stamps. * fns.c (Frandom): Use nanoseconds, not microseconds, for seed. * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps. * image.c (prepare_image_for_display, clear_image_cache) (lookup_image): Port to higer-resolution time stamps. * keyboard.c (start_polling, bind_polling_period): Check for time stamp overflow.

Do not assume time_t is signed. (decode_timer): New function. Timers are now vectors of length 9, not 8, to accommodate the picosecond component. (timer_check_2): Use it. * nsterm.m (select_timeout, timeval_subtract): Remove. (ns_timeout): Use Emacs's facilities for time stamp arithmetic, as they're a bit more accurate and handle overflow better. (ns_select): Change prototype to be compatible with pselect. (ns_select, ns_term_shutdown): Port to ns-resolution time stamps. * nsterm.h (ns_select): Adjust prototype. * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes us-resolution time stamps. (sys_select): Use the new EMACS_TIME_SIGN macro instead. * lread.c (read_filtered_event): Port to ns-resolution time stamps. * lisp.h (time_overflow): New decl. (wait_reading_process_output): First arg is now intmax_t, not int, to accommodate larger waits. * process.h (struct Lisp_Process.read_output_delay): Now counts nanoseconds, not microseconds. * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about EMACS_HAS_USECS. (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output) (wait_reading_process_output): Port to ns-resolution time stamps. (Faccept_process_output, wait_reading_process_output): Check for time stamp overflow. Do not assume time_t is signed. (select_wrapper): Remove; we now use pselect. (Fprocess_attributes): Now generates ns-resolution time stamps. * sysdep.c: Include utimens.h. Don't include utime.h or worry about struct utimbuf; gnulib does that for us now. (gettimeofday): Remove; gnulib provides a substitute. (make_timeval): New function. (set_file_times): Now sets ns-resolution time stamps. New arg FD; all uses changed. (time_from_jiffies, ltime_from_jiffies, get_up_time) (system_process_attributes): Now returns ns-resolution time stamp. All uses changed. Check for time stamp overflow. * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib provides a substitute now. * systime.h: Include timespec.h rather than sys/time.h and time.h, since it guarantees struct timespec. (EMACS_TIME): Now struct timespec, so that we can support ns-resolution time stamps. (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros. (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now. (EMACS_USECS): Remove. (EMACS_SET_USECS): The underlying time stamp now has ns resolution, so multiply the arg by 1000 before storing it. (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS): New macros. (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME): Port to ns-resolution time stamps. (EMACS_TIME_NEG_P): Remove; replaced by.... (EMACS_TIME_SIGN): New macro. (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P) (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros. (set_file_times, make_time, lisp_time_argument): Adjust signature. (make_timeval, make_lisp_time, decode_time_components): New decls. (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in that it mishandled time_t overflow. You can't compare by subtracting! (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE) (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp. * term.c: Include .

(term_mouse_position, term_mouse_click): Use it. * undo.c (record_first_change): Support higher-resolution time stamps in the undo buffer. (Fprimitive_undo): Use them when restoring time stamps. * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull) (w32_get_internal_run_time): Port to higher-resolution Emacs time stamps. (ltime): Now accepts single 64-bit integer, as that's more convenient for callers. * xdisp.c (start_hourglass): Port to ns-resolution time stamps. * xgselect.c, xgselect.h (xg_select): Add sigmask argument, for compatibility with pselect. Support ns-resolution time stamps. * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps. * xselect.c (wait_for_property_change, x_get_foreign_selection): Check for time stamp overflow, and support ns-resolution time stamps. * xterm.c: Don't include sys/time.h; gnulib does that for us now. Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set. (timeval_subtract): Remove; no longer needed. (XTflash, XTring_bell, x_wait_for_event): Port to ns-resolution time stamps. Don't assume time_t is signed. 2012-06-22 Chong Yidong * xdisp.c (x_consider_frame_title): Revert last change. 2012-06-22 Eli Zaretskii * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER aborts in staticpro during startup. (Without -DBYTE_CODE_METER, staticidx goes up to 1597 out of 1600 = 0x640.) 2012-06-20 Paul Eggert * fileio.c (Fdefault_file_modes): Block input while fiddling with umask. Otherwise, the umask might be mistakenly 0 while handling input signals. 2012-06-19 Stefan Monnier * minibuf.c (Fread_string): Bind minibuffer-completion-table. 2012-06-19 Dmitry Antipov * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c: * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c: * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct access to `contents' member of Lisp_Vector objects with AREF and ASET where appropriate. 2012-06-19 Chong Yidong * frame.c (delete_frame): When selecting a frame on a different text terminal, do not alter the terminal's top-frame. * xdisp.c (format_mode_line_unwind_data): Record the target frame's selected window and its terminal's top-frame. (unwind_format_mode_line): Restore them. (x_consider_frame_title, display_mode_line, Fformat_mode_line): Callers changed. (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM, since tty frames can be explicitly named.

(METER_1, METER_2): Simplify. 2012-06-18 Stefan Monnier * data.c (Fdefalias): Return `symbol' (bug#11686). 2012-06-18 Martin Rudalics * buffer.c (Fkill_buffer): Don't throw an error when the buffer gets killed during executing of this function (Bug#11665). Try to always return Qt when the buffer has been actually killed. (Vkill_buffer_query_functions): In doc-string say that functions run by this hook should not change the current buffer. 2012-06-18 Paul Eggert Fix recently-introduced process.c problems found by static checking. * process.c (write_queue_push, write_queue_pop, send_process): Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.

(send_process): Remove unused local. 2012-06-17 Chong Yidong * xdisp.c (redisplay_internal): No need to redisplay terminal frames that are not on top. 2012-06-17 Troels Nielsen * process.c (make_process): Initialize write_queue. (write_queue_push, write_queue_pop): New functions. (send_process): Use them to maintain correct ordering of process writes (Bug#10815). 2012-06-17 Paul Eggert * lisp.h (eassert): Assume C89 or later. This removes the need for CHECK. (CHECK): Remove. Its comments about always evaluating its argument were confusing, as 'eassert' typically does not evaluate its argument. * coding.c (produce_chars): Use ptrdiff_t, not int. * xterm.c (x_draw_underwave): Check for integer overflow. This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64. 2012-06-17 Jan Djärv * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't referenced (Bug#11583). 2012-06-16 Aurélien Aptel Implement wave-style variant of underlining. * dispextern.h (face_underline_type): New enum.

If all the glyphs of the glyph row came from strings, and we have no cursor positioning clues, put the cursor on the first glyph of the row. (handle_face_prop): Use chunk-relative overlay string index when indexing into it->string_overlays array. (Bug#11653) (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not the rightmost.

(Bug#11677) 2012-06-14 Paul Eggert * .gdbinit (xgetint): Fix recently-introduced paren typo. Assume USE_2_TAGS_FOR_INTS. (xreload): Adjust $tagmask width to match recent lisp.h change. Simplify lisp.h in minor ways that should not affect code. * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined. (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P) (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number): Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined. (INTTYPEBITS): New macro, for clarity. (INTMASK, MOST_POSITIVE_FIXNUM): Use it. (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P): Simplify now that USE_LSB_TAG is always defined. (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast. (make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler. 2012-06-13 Juanma Barranquero * makefile.w32-in ($(BLD)/data.$(O)): Update dependencies. 2012-06-13 Glenn Morris * s/bsd-common.h (BSD4_3): * s/usg5-4-common.h (USG5_4): No longer define; unused. 2012-06-13 Andreas Schwab * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct instead of union.

(mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now. (roundup_size): Verify that it is a power of 2. * data.c (Fmake_variable_buffer_local, Fmake_local_variable): * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO. * lisp.h (USE_LSB_TAG): Allow the builder to compile with -DUSE_LSB_TAG=0, to override the automatically-selected default. USE_LSB_TAG now is always defined to be either 0 or 1. All uses changed. (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the code works fine either way, and efficiency is not a concern here, as the union type is for debugging, not for production. (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]: Use an inline function on all platforms when using the union type, since this is simpler and 'static inline' can be used portably within Emacs now. (LISP_INITIALLY_ZERO): New macro. (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove. (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize. 2012-06-12 Glenn Morris * s/gnu-kfreebsd.h, s/hpux11.h, s/openbsd.h, s/sol2-10.h: Remove files. * s/gnu-linux.h (HAVE_PROCFS): Move to configure. * s/hpux10-20.h, s/openbsd.h, s/usg5-4-common.h: Move BROKEN_SIGIO to configure. * s/bsd-common.h, s/darwin.h, s/gnu-kfreebsd.h, s/hpux10-20.h: Move NO_TERMIO to configure. 2012-06-12 Chong Yidong * image.c (imagemagick_load_image): Use MagickFlattenImage if MagickMergeImageLayers is undefined.

Remove unused blink field. * xfaces.c (tty_supports_face_attributes_p, realize_tty_face): Handle slant. * dispextern.h: Replace unused TTY_CAP_BLINK with TTY_CAP_ITALIC. (struct face): Remove unused fields tty_dim_p, tty_blinking_p, and tty_alt_charset_p. Add tty_italic_p. 2012-06-09 Michael Albinus * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and dbus_type_is_basic if available. (xd_extract_signed, xd_extract_unsigned): Rename from extract_signed and extract_unsigned, respectively. Adapt callers. 2012-06-09 Chong Yidong * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066). * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive case (Bug#9752). 2012-06-08 Paul Eggert * xdisp.c (vmessage): Treat frame message as multibyte. Without this change, (let ((§ 1)) (make-variable-buffer-local '§)) would generate the diagnostic "Making \302\247 buffer-local while let-bound!". 2012-06-08 Eli Zaretskii * dispnew.c (showing_window_margins_p): Undo last change, which was done due to an inadvertent commit.

Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP) would mishandle a string argument "Xc" if X was a multibyte character of length 2: it would truncate after X's first byte rather than including all of X. 2012-06-06 Chong Yidong * buffer.c (word_wrap): Doc fix. 2012-06-04 Paul Eggert * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall. 2012-06-03 Glenn Morris * xdisp.c (tool-bar-style): Doc fix. 2012-06-03 Ulrich Müller * Makefile.in (PAXCTL): Define.

Rename 'mini_p' field to 'mini', change its type from Lisp_Object to bitfield. Change type of 'force_start', 'optional_new_start', 'last_had_star', 'update_mode_line' and 'start_at_line_beg' fields from Lisp_Object to bitfield. Adjust users accordingly. 2012-05-31 Paul Eggert Pacify gcc -Wdouble-precision when using Xaw. * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb) [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]: Use 'float' consistently, rather than 'float' in most places and 'double' in a couple of places. 2012-05-31 Eli Zaretskii * xdisp.c (handle_stop): Detect whether we have overlay strings loaded by testing it->current.overlay_string_index to be non-negative, instead of checking whether n_overlay_strings is positive. (Bug#11587) 2012-05-31 Chong Yidong * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169). * doc.c (Fsubstitute_command_keys): Doc fix. 2012-05-31 Eli Zaretskii * search.c (search_buffer): Remove calls to r_alloc_inhibit_buffer_relocation, as it is now called by maybe_unify_char, which was the cause of relocation of buffer text in bug#11519. 2012-05-31 Eli Zaretskii * charset.c (maybe_unify_char): Inhibit relocation of buffer text for the duration of call to load_charset, to avoid problems with callers of maybe_unify_char that access buffer text through C pointers. * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and decrement the inhibition flag, instead of just setting or resetting it. 2012-05-31 Paul Eggert Remove obsolete '#define static' cruft. * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef. This #undef was "temporary" in 2000; it is no longer needed now that '#define static' has gone away. * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height) (gray_bitmap_bits): Remove; no longer needed. All uses replaced with definiens. * xterm.c: Include "bitmaps/gray.xbm". 2012-05-30 Paul Eggert Clean up __executable_start, monstartup when --enable-profiling. The following changes affect the code only when profiling. * dispnew.c (__executable_start): Rename from safe_bcopy. Define only on platforms that need it. * emacs.c: Include when profiling. (_mcleanup): Remove decl, since does it now. (__executable_start): Remove decl, since lisp.h does it now. (safe_bcopy): Remove decl; no longer has that name. (main): Coalesce #if into single bit of code, for simplicity.

(Fdelete_overlay): Cosmetics. 2012-05-28 Eli Zaretskii * w32term.c (my_bring_window_to_top): New function. (x_raise_frame): Use handle returned by DeferWindowPos, which could be different from the original one. Call my_bring_window_to_top instead of my_set_foreground_window. (Bug#11513) * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP by calling BringWindowToTop. * w32term.h (WM_EMACS_BRINGTOTOP): New message. (WM_EMACS_END): Increase by one. 2012-05-28 Paul Eggert * bidi.c (bidi_mirror_char): Put eassert before conversion to int. This avoids undefined behavior that might cause the eassert to not catch an out-of-range value. 2012-05-28 Juanma Barranquero * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)): Update dependencies. 2012-05-27 Eli Zaretskii * bidi.c (bidi_mirror_char): Fix last change. 2012-05-27 Andreas Schwab * unexmacosx.c (copy_data_segment): Truncate after 16 characters when referring to sectname field in printf format. 2012-05-27 Paul Eggert * lisp.h [REL_ALLOC]: Omit duplicate prototypes.

Put the check inside eassert. See . 2012-05-27 Ken Brown * callproc.c (Fcall_process): Restore a line that was accidentally commented out in the 2011-02-13 change (bug#11547). 2012-05-27 Eli Zaretskii * lisp.h [REL_ALLOC]: Add prototypes for external functions defined on ralloc.c. * buffer.c [REL_ALLOC]: Remove prototypes of r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free, they are now on lisp.h. * ralloc.c (r_alloc_inhibit_buffer_relocation): New function. * search.c (search_buffer): Use it to inhibit relocation of buffer text while re_search_2 is doing its job, because re_search_2 is passed C pointers to buffer text. (Bug#11519) * msdos.c (internal_terminal_init) : Update value to 24. * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator state after an additional call to move_it_in_display_line_to, keep the values of it->max_ascent and it->max_descent found for the entire line. (pos_visible_p): Revert the comparison against bottom_y to what it was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb. (Bug#11464) 2012-05-26 Paul Eggert Fix coding-related core dumps with gcc -ftrapv. The code was computing A - B, where A and B are pointers, and B is random garbage. This can lead to core dumps on platforms that have special pointer registers, and it also leads to core dumps on x86-64 when compiled with gcc -ftrapv. The fix is to compute A - B only when B is initialized properly. * coding.c (coding_set_source, coding_set_destination): Return void. (coding_change_source, coding_change_destinations): New functions, with the old behaviors of coding_set_source and coding_set_destination. All callers that need an offset changed to use these new functions. 2012-05-26 Glenn Morris * nsterm.m (ns_init_paths): Don't mess with INFOPATH.

(allocate_pseudovector): Use int, not EMACS_INT, where int is wide enough. (inhibit_garbage_collection, Fgarbage_collect): Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts. * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where int might not be wide enough.

(Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change): Omit pointer cast, which isn't needed anyway, and doesn't work after the EMACS_INT -> ptrdiff_t change. (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow. * buffer.h: Adjust decls to match defn changes elsewhere. (struct buffer_text, struct buffer): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

Use lint_assume to convince GCC 4.6.1 that it's OK. * category.c (Fchar_category_set): Don't assume fixnum fits in int. * category.h (CATEGORYP): Don't assume arg is nonnegative. * ccl.c (GET_CCL_INT): Remove; no longer needed, since the integers are now checked earlier. All uses replaced with XINT. (ccl_driver): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough. For CCL_MapSingle, check that content and value are in int range. (ccl_driver, Fregister_code_conversion_map): Check that Vcode_version_map_vector is a vector. (resolve_symbol_ccl_program): Check that vector header is in range.

Don't rely on undefined behavior with signed left shift overflow. Don't assume unsigned int fits into fixnum, or that fixnum fits into unsigned int. Don't require max_code to be a valid fixnum; that's not true for gb10830 4-byte on a 32-bit host. Allow invalid_code to be a cons, for the same reason. Require code_offset to be a character. Avoid int overflow if max_char is close to INT_MAX. (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned; this is intended anyway and avoids some undefined behavior.

(CHARSET_OFFSET): Remove unused macro, instead of fixing its integer-overflow issues. (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts. Formerly, it returned EMACS_INT on 64-bit hosts in the common case where the argument is EMACS_INT, and this behavior is not intended. * chartab.c (Fmake_char_table, Fset_char_table_range) (uniprop_get_decoder, uniprop_get_encoder): Don't assume fixnum fits in int. * cmds.c (move_point): New function, that does the gist of Fforward_char and Fbackward_char, but does so while checking for integer overflow more accurately. (Fforward_char, Fbackward_char): Use it. (Fforward_line, Fend_of_line, internal_self_insert) (internal_self_insert): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

(Bug#11417) (pos_visible_p): Don't report a position visible when move_it_to stopped at the last line of window, which happens to be scanned backwards by the bidi iteration. (Bug#11464) 2012-05-14 Eli Zaretskii * xdisp.c (handle_single_display_spec): Return 1 for left-margin and right-margin display specs even if the spec is invalid or we are on a TTY, and thus unable to display on the fringes. That's because the text with the property will not be displayed anyway, so we need to signal to the caller that this is a "replacing" display spec. This fixes display when the spec is invalid or we are on a TTY. 2012-05-14 Paul Eggert * unexaix.c (make_hdr): Fix typo in prototype. This bug broke the build on AIX. Problem reported by Gilles Pion. 2012-05-14 Michael Albinus * keyboard.c (kbd_buffer_get_event): Read special events also in batch mode. (Bug#11415) 2012-05-12 Glenn Morris * ns.mk: Update for ns_appbindir no longer having trailing "/". 2012-05-12 Eli Zaretskii * lisp.mk (lisp): Add newcomment.elc. 2012-05-12 Glenn Morris * Makefile.in (MKDIR_P): New, set by configure. * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P. 2012-05-11 Paul Eggert Remove unused function hourglass_started. * dispextern.h (hourglass_started): * w32fns.c (hourglass_started): * xdisp.c (hourglass_started): Remove. 2012-05-10 Juanma Barranquero * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)): Update dependencies. 2012-05-10 Paul Eggert * xgselect.c (xg_select): Put maxfds+1 into a var. This is slightly clearer, and pacifies Ubuntu 12.04 gcc. * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA. 2012-05-10 Dave Abrahams * filelock.c (syms_of_filelock): New boolean create-lockfiles. (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227) 2012-05-09 Michael Albinus * dbusbind.c (xd_registered_buses): New internal Lisp object. Rename all occurrences of Vdbus_registered_buses to xd_registered_buses. (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses. Initialize xd_registered_buses. 2012-05-09 Paul Eggert Untag more efficiently if USE_LSB_TAG. This is based on a proposal by YAMAMOTO Mitsuharu in . For an admittedly artificial (nth 8000 longlist) benchmark on Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks Emacs's overall text size by 1%. * lisp.h (XUNTAG): New macro. (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW) (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR) (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it. * eval.c (Fautoload): * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT): * frame.h (XFRAME): Use XUNTAG. Port recent dbusbind.c changes to 32-bit --with-wide-int. * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal): Remove unportable assumptions about print widths of types like dbus_uint32_t. (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to intptr_t when converting between pointer and integer, to avoid GCC warnings about wrong width. 2012-05-09 Eli Zaretskii * w32proc.c (new_child): Force Windows to reserve only 64KB of stack for each reader_thread, instead of defaulting to 8MB determined by the linker. This avoids failures in creating subprocesses on Windows 7, see the discussion in this thread: https://lists.gnu.org/r/emacs-devel/2012-03/msg00119.html. 2012-05-07 Jérémy Compostella Fix up display of the *Minibuf-0* buffer in the mini window. * keyboard.c (read_char): Don't clear the echo area if there's no message to clear. * xdisp.c (redisplay_internal): Redisplay the mini window (with the contents of *Minibuf-0*) if there's no message displayed in its stead. 2012-05-07 Michael Albinus * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in batch mode. 2012-05-06 Chong Yidong * lisp.mk (lisp): Update. 2012-05-05 Jim Meyering * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372). 2012-05-04 Stefan Monnier * data.c (PUT_ERROR): New macro. (syms_of_data): Use it. Add new error type `user-error'. * undo.c (user_error): New function. (Fprimitive_undo): Use it. * print.c (print_error_message): Adjust print style for `user-error'. * keyboard.c (user_error): New function. (Fexit_recursive_edit, Fabort_recursive_edit): Use it. 2012-05-03 Paul Eggert Do not limit current-time-string to years 1000..9999. * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove. (Fcurrent_time_string): Support any year that is supported by the underlying localtime representation. Don't use asctime, as it has undefined behavior for years outside the range -999..9999. 2012-05-02 Paul Eggert Fix race conditions involving setenv, gmtime, localtime, asctime. Without this fix, interrupts could mess up code that uses these nonreentrant functions, since setting TZ invalidates existing tm_zone or tzname values, and since most of these functions return pointers to static storage. * editfns.c (format_time_string, Fdecode_time, Fencode_time) (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule): Grow the critical sections to include not just invoking localtime/gmtime, but also accessing these functions' results including their tm_zone values if any, and any related TZ setting. (format_time_string): Last arg is now struct tm *, not struct tm **, so that the struct tm is saved in the critical section. All callers changed. Simplify allocation of initial buffer, partly motivated by the fact that memory allocation needs to be outside the critical section. 2012-05-02 Dmitry Antipov * intervals.c (adjust_intervals_for_insertion): Initialize `newi' with RESET_INTERVAL. * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): Remove duplicated buffer name initialization. 2012-05-02 Jim Meyering * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373). * xfns.c (x_window): Use xstrdup (Bug#11375). 2012-05-02 Eli Zaretskii * xdisp.c (pos_visible_p): If already at a newline from the display string before the 'while' loop, don't walk back the glyphs from it3.glyph_row. Solves assertion violation when the display string begins with a newline (egg.el). (Bug#11367) 2012-05-01 Stefan Monnier * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings): Move to simple.el. 2012-05-01 Glenn Morris * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h), and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10). All were removed before 23.1. * dispnew.c: Remove HAVE_LIBNCURSES test; it is always true on relevant platforms. * Makefile.in (LD_SWITCH_X_SITE_RPATH): Rename from LD_SWITCH_X_SITE_AUX_RPATH. * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used. 2012-04-30 Andreas Schwab * .gdbinit (xpr): Remove checks for no longer existing misc types. (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal): Remove. 2012-04-28 Paul Eggert Do not avoid creating empty evaporating overlays (Bug#9642). * buffer.c (Fmove_overlay): Revert the change of 2012-04-23. That is, do not delete an evaporating overlay if it becomes empty after its bounds are adjusted to fit within its buffer. This fix caused other problems, and I'm reverting it until we get to the bottom of them. 2012-04-27 Chong Yidong * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315). 2012-04-27 Eli Zaretskii * xdisp.c (pos_visible_p): If the window start position is beyond ZV, start the display from buffer beginning. Prevents assertion violation in init_iterator when the minibuffer window is scrolled via the scroll bar. * window.c (window_scroll_pixel_based): Likewise. 2012-04-27 Chong Yidong * keymap.c (where_is_internal): Doc fix (Bug#10872). 2012-04-27 Glenn Morris * fileio.c (Fcopy_file, Fset_file_selinux_context): Ignore ENOTSUP failures from setfilecon functions. (Bug#11245) 2012-04-27 Eli Zaretskii * dispnew.c (swap_glyph_pointers, copy_row_except_pointers): Don't overrun array limits of glyph row's used[] array. (Bug#11288) 2012-04-26 Eli Zaretskii * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded display element, check also the underlying string or buffer character. (Bug#11341) * w32menu.c: Include w32heap.h. (add_menu_item): If the call to AppendMenuW (via unicode_append_menu) fails, disable Unicode menus only if we are running on Windows 9X/Me. 2012-04-24 Andreas Schwab * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS. (xgetint): Add missing shift for LSB tags. 2012-04-24 Martin Rudalics * keyboard.c (read_char): Don't wipe echo area for select window events: These might get delayed via `mouse-autoselect-window' (Bug#11304). 2012-04-24 Juanma Barranquero * gnutls.c (init_gnutls_functions): Protect against (unlikely) manipulation of :loaded-from data. 2012-04-23 Juanma Barranquero * gnutls.c (init_gnutls_functions): The value of :loaded-from is now a cons (bug#11311). 2012-04-23 Paul Eggert Do not create empty overlays with the evaporate property (Bug#9642). * buffer.c (Fmove_overlay): Delete an evaporating overlay if it becomes empty after its bounds are adjusted to fit within its buffer. Without this fix, in a nonempty buffer (let ((o (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1)) yields an empty overlay that has the evaporate property, which is not supposed to happen. Fix minor GTK3 problems found by static checking. * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed) (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed) (struct _EmacsFixedClass, emacs_fixed_get_type): Move decls here from emacsgtkfixed.h, since they needn't be public. (emacs_fixed_get_type): Now static. (emacs_fixed_class_init): Omit unused local. (emacs_fixed_child_type): Remove; unused. * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed) (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed) (struct _EmacsFixedClass): Move to emacsgtkfixed.c. (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS) (EMACS_FIXED_GET_CLASS): Remove; unused. * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local. * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO. Problem reported by Juanma Barranquero for Windows -Wunused-function. 2012-04-22 Paul Eggert Modernize and clean up gmalloc.c to assume C89 (Bug#9119). * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t) (__malloc_size_t, __malloc_ptrdiff_t): Remove. All uses removed, replaced by the definiens if needed, since we can assume C89 or better now. Include , for PTRDIFF_MAX, uintptr_t. (protect_malloc_state, align, get_contiguous_space) (malloc_atfork_handler_prepare, malloc_atfork_handler_parent) (malloc_atfork_handler_child, malloc_enable_thread) (malloc_initialize_1, __malloc_initialize, morecore_nolock) (_malloc_internal_nolock, _malloc_internal, malloc, _malloc) (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree) (special_realloc, _realloc_internal_nolock, _realloc_internal) (realloc, calloc, __default_morecore, memalign, valloc, checkhdr) (freehook, mallochook, reallochook, mabort, mcheck, mprobe): Define using prototypes, not old style. (align, _malloc_internal_nolock, _free_internal_nolock, memalign): Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long. (align): Don't assume that signed integer overflow wraps around. Omit unused local var. (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock) (_free_internal_nolock, memalign, mallochook, reallochook): Omit no-longer-needed casts. (valloc): Use getpagesize, not __getpagesize. (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit. (struct hdr): The 'magic' member is now size_t, not unsigned long. * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed. 2012-04-22 Michael Albinus Move functions from C to Lisp. Make non-blocking method calls the default. Implement further D-Bus standard interfaces. * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare. (QCdbus_request_name_allow_replacement) (QCdbus_request_name_replace_existing) (QCdbus_request_name_do_not_queue) (QCdbus_request_name_reply_primary_owner) (QCdbus_request_name_reply_in_queue) (QCdbus_request_name_reply_exists) (QCdbus_request_name_reply_already_owner): Move to dbus.el.

(xd_get_connection_address): Rename from xd_initialize. Return cached address. (xd_remove_watch): Do not unset $DBUS_SESSION_BUS_ADDRESS. (xd_close_bus): Rename from Fdbus_close_bus. Not needed on Lisp level. (Fdbus_init_bus): New optional arg PRIVATE. Cache address. Return number of refcounts. (Fdbus_get_unique_name): Make stronger parameter check. (Fdbus_message_internal): New defun. (Fdbus_call_method, Fdbus_call_method_asynchronously) (Fdbus_method_return_internal, Fdbus_method_error_internal) (Fdbus_send_signal, Fdbus_register_service) (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el. (xd_read_message_1): Obey new structure of Vdbus_registered_objects. (xd_read_queued_messages): Obey new structure of Vdbus_registered_buses. (Vdbus_compiled_version, Vdbus_runtime_version) (Vdbus_message_type_invalid, Vdbus_message_type_method_call) (Vdbus_message_type_method_return, Vdbus_message_type_error) (Vdbus_message_type_signal): New defvars. (Vdbus_registered_buses, Vdbus_registered_objects_table): Adapt docstring. 2012-04-22 Paul Eggert Fix GC_MALLOC_CHECK debugging output on 64-bit hosts. * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]: Do not assume ptrdiff_t is the same width as 'int'. * alloc.c: Handle unusual debugging option combinations. (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK, since the two debugging options are incompatible. (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS is defined. (mem_init, mem_insert, mem_insert_fixup): Define if GC_MARK_STACK || GC_MALLOC_CHECK. (NEED_MEM_INSERT): Remove; no longer needed. 2012-04-22 Leo Liu * sysdep.c (list_system_processes): Support Darwin (Bug#5725). 2012-04-22 Paul Eggert * sysdep.c [__FreeBSD__]: Minor cleanups. (list_system_processes, system_process_attributes) [__FreeBSD__]: Use Emacs indenting style more consistently. Avoid some casts. Use 'double' consistently rather than mixing 'float' and 'double'. 2012-04-21 Eduard Wiebe * sysdep.c (list_system_processes, system_process_attributes): Add implementation for FreeBSD (Bug#5243). 2012-04-21 Andreas Schwab * lisp.mk (lisp): Update. 2012-04-20 Paul Eggert * keyboard.c (process_pending_signals): Define only if SYNC_INPUT. It is never used otherwise. 2012-04-20 Stefan Monnier * print.c (print_preprocess): Only check print_depth if print-circle is nil. (print_object): Check for cycles even when print-circle is nil and print-gensym is t, but only check print_depth if print-circle is nil. 2012-04-20 Chong Yidong * process.c (wait_reading_process_output): If EIO occurs on a pty, set the status to "failed" and ensure that sentinel is run. 2012-04-20 Glenn Morris * process.c (Fset_process_inherit_coding_system_flag) (Fset_process_query_on_exit_flag): Doc fix (mention return value).

(set_cursor_from_row): If called for a mode-line or header-line row, return zero immediately. (try_cursor_movement): If inside continuation line, don't back up farther than the first row after the header line, if any. Don't consider the header-line row as "partially visible", even if MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261) 2012-04-20 Atsuo Ohki (tiny change) * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n" (bug#11238). 2012-04-20 Teodor Zlatanov 2012-04-18 Paul Eggert configure: new option --enable-gcc-warnings (Bug#11207) * Makefile.in (C_WARNINGS_SWITCH): Remove. (WARN_CFLAGS, WERROR_CFLAGS): New macros. (ALL_CFLAGS): Use new macros rather than old. * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904. * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore -Wunused-but-set-variable, -Wunused-function, -Wunused-macros, -Wunused-result, -Wunused-variable. This should go away once the Emacs and Gnulib regex code is merged. (xmalloc, xrealloc): Now static. 2012-04-17 Paul Eggert * dired.c (Fsystem_groups): Remove unused local. 2012-04-17 Glenn Morris * dired.c (Fsystem_users): Doc fix. 2012-04-17 Dmitry Antipov * dired.c (Fsystem_users, Fsystem_groups): New functions.

(NEED_MEM_INSERT): New macro. (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused. Remove one incorrect comment and fix another. Fix minor ralloc.c problems found by static checking. See https://lists.gnu.org/r/emacs-devel/2011-12/msg00720.html * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE) (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused. (r_alloc_sbrk): Now static. Improve ralloc.c interface checking. See https://lists.gnu.org/r/emacs-devel/2011-12/msg00720.html * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc) (r_alloc_free) [REL_ALLOC]: Move decls from here ... * lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable) [REL_ALLOC]: ... to here, to check interface. * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]: Remove decls. This fixes an "It stinks!". * alloc.c (which_symbols): Fix alignment issue / type clash. 2012-04-15 Andreas Schwab * lisp.h (struct Lisp_Symbol): Remove explicit padding. (struct Lisp_Misc_Any): Likewise. (struct Lisp_Free): Likewise. * alloc.c (union aligned_Lisp_Symbol): Define.

(Bug#11036) * Makefile.in ($(leimdir)/leim-list.el): Pass EMACS rather than BUILT_EMACS. 2012-04-09 Teodor Zlatanov * process.c (make_process): * process.h: Add integer `gnutls_handshakes_tried' member to process struct. * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit. Add convenience `GNUTLS_LOG2i' macro. * gnutls.c (gnutls_log_function2i): Convenience log function. (emacs_gnutls_read): Use new log functions, `gnutls_handshakes_tried' process member, and `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake attempts per process (connection). 2012-04-09 Chong Yidong * eval.c (Fuser_variable_p, user_variable_p_eh) (lisp_indirect_variable): Functions deleted. (Fdefvar): Caller changed. * callint.c (Finteractive, Fcall_interactively): * minibuf.c (Fread_variable): Callers changed. 2012-04-09 Eli Zaretskii * xdisp.c (set_cursor_from_row): If the display string appears in the buffer at position that is closer to point than the position after the display string, display the cursor on the first glyph of the display string. Fixes cursor display when a 'display' text property immediately follows invisible text. (Bug#11094) 2012-04-09 Paul Eggert composite.c: use 'double' consistently * composite.c (get_composition_id): Use 'double' consistently instead of converting 'float' to 'double' and vice versa; this is easier to understand and avoids a GCC warning. 2012-04-09 Glenn Morris * Makefile.in: Generate leim-list with bootstrap-emacs, in preparation for dumping it with emacs. (Bug#4789) (leimdir): New variable. ($(leimdir)/leim-list.el): New rule. (emacs$(EXEEXT)): Depend on leim-list.el. * buffer.c (Qucs_set_table_for_input): Remove.

(mark_memory): Mark Lisp_Objects only if pointers might hide in objects, as mark_maybe_pointer will catch them otherwise. (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed. * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise. 2012-04-07 Paul Eggert Fix typo that broke non-Windows builds. * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'. 2012-04-07 Eli Zaretskii Support building on MS-Windows with libxml2. * makefile.w32-in (OBJ2): Add xml.$(O).

(Bug#11141) 2012-03-31 Eli Zaretskii * xdisp.c (move_it_by_lines): When DVPOS is positive, and the position we get to after a call to move_it_to fails the IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position only if we wind up in a string from display property. (Bug#11063) * window.c (Fdelete_other_windows_internal): Invalidate the row and column information about mouse highlight, so that redisplay restores it after reallocating the glyph matrices. (Bug#7464) * xdisp.c (set_cursor_from_row): If `cursor' property on a display string comes from a `display' text property, use the buffer position of that property as if we actually saw that position in the row's glyphs.

(next_overlay_string): If there's an empty string on the iterator stack, pop the stack. (Bug#10903) 2012-02-25 Paul Eggert Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780). Suggested by Stefan Monnier in . * alloc.c (widen_to_Lisp_Object): New static function. (mark_memory): Also mark Lisp_Objects by fetching pointer words and widening them to Lisp_Objects.

It's useless in that case, and it can cause problems on hosts that allocate halves of EMACS_INT values separately. Reported by Dan Horák. Diagnosed by Andreas Schwab in . * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where UINTPTR_MAX >> VALBITS == 0.

(Vtemp_buffer_show_specifiers): Remove unused variable. 2011-10-30 Eli Zaretskii * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented past the beginning of the current glyph matrix. 2011-10-30 Adam Sjøgren (tiny change) * xterm.c: Include X11/Xproto.h if HAVE_GTK3. (x_error_handler): Ignore BadMatch for X_SetInputFocus for HAVE_GTK3 (Bug#9869). * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize type to GDK_NOTHING so valgrind does not complain (Bug#9901). * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893). * xterm.c: Declare x_handle_net_wm_state to return int. (handle_one_xevent): Check if we are iconified but don't have _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893). (get_current_wm_state): Return non-zero if not hidden, check for _NET_WM_STATE_HIDDEN (Bug#9893). (do_ewmh_fullscreen): Ignore return value from get_current_wm_state. (x_handle_net_wm_state): Return what get_current_wm_state returns. (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden. 2011-10-29 Paul Eggert * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE, so that this new function doesn't get optimized away by a whole-program optimizer. Make the 2nd arg EMACS_INT, not int. 2011-10-29 Andreas Schwab * frame.h (MOUSE_HL_INFO): Remove excess parens. 2011-10-29 Eli Zaretskii Fix the `xbytecode' command. * .gdbinit (xprintbytestr): New command. (xwhichsymbols): Rename from `which'; all callers changed. (xbytecode): Print the byte-code string as well. 2011-10-29 Kim Storm * alloc.c (which_symbols): New function. 2011-10-29 Andreas Schwab * minibuf.c (read_minibuf_noninteractive): Allow reading empty line. (Bug#9903) 2011-10-29 Glenn Morris * process.c (wait_reading_process_output): Revert 2009-08-30 change. Not clear what it was for, and it causes various bugs. (Bug#9839) 2011-10-28 Eli Zaretskii * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a possible random value that matches one of those tested as condition to clear the mouse face. 2011-10-28 Chong Yidong * xdisp.c (note_mouse_highlight): Fix use of uninitialized var. 2011-10-28 Dan Nicolaescu * window.c (make_window): Initialize phys_cursor_on_p. 2011-10-28 Stefan Monnier * lisp.h (struct Lisp_Symbol): Update comments. 2011-10-28 Juanma Barranquero * w32font.c (w32_load_unicows_or_gdi32): Add missing return. 2011-10-28 Eli Zaretskii Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem for helping to debug this. * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w) (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w) (g_b_init_get_glyph_outline_w): New static variables.

(w32_load_unicows_or_gdi32, get_outline_metrics_w) (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font): New functions. (w32font_open_internal, compute_metrics): Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w instead of calling the "wide" APIs directly. * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font. * w32.h (syms_of_w32font): Add prototype. 2011-10-27 Juanma Barranquero * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end) (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window) (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings. (Fmove_to_window_line): Doc fix. 2011-10-27 Chong Yidong * process.c (make_process): Set gnutls_state to NULL. * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is non-NULL, regardless of GNUTLS_INITSTAGE. (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal an error. Set process slots as soon as we allocate them. * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros. 2011-10-27 Chong Yidong * gnutls.c (emacs_gnutls_deinit): New function.

(deactivate_process): Call emacs_gnutls_deinit. 2011-10-27 Juanma Barranquero * image.c (x_create_x_image_and_pixmap): * w32.c (sys_rename, w32_delayed_load): * w32font.c (fill_in_logfont): * w32reg.c (x_get_string_resource): Silence compiler warnings. 2011-10-26 Juanma Barranquero * w32fns.c (w32_default_color_map): New function, extracted from Fw32_default_color_map. (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785) 2011-10-25 Paul Eggert * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2). 2011-10-25 Stefan Monnier * keyboard.c (test_undefined): New function (bug#9751). (read_key_sequence): Use it to detect when a key is bound to `undefined'. 2011-10-25 Enami Tsugutomo * sysdep.c (init_sys_modes): Fix the check for the controlling terminal (Bug#6649). 2011-10-20 Eli Zaretskii * dispextern.h (struct bidi_it): New member next_en_type. * bidi.c (bidi_line_init): Initialize the next_en_type member. (bidi_resolve_explicit_1): When next_en_pos is valid for the current character, check also for next_en_type being WEAK_EN. (bidi_resolve_weak): Don't enter the expensive loop if the current position is before next_en_pos. Record the bidi type of the first non-ET, non-BN character we find, in addition to its position. (bidi_level_of_next_char): Invalidate next_en_type when next_en_pos is over-stepped. 2011-10-20 Paul Eggert Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794) * editfns.c: Rewrite current-time-zone so that it invokes the equivalent of (format-time-string "%Z") to get the time zone name. This fixes a bug when the time zone name contains characters that need converting from the system time locale to Emacs internal format. This fixes a shortcoming that I introduced in my 1999-10-19 patch: that patch fixed format-time-string to do the conversion, but I forgot to fix current-time-zone. (format_time_string): New function, containing most of what Fformat_time_string used to contain. (Fformat_time_string): Rewrite in terms of format_time_string. This doesn't change this function's behavior. (current-time-zone): Rewrite to use format_time_string. This fixes the bug reported by Michael Schierl in . Jason Rumney's 2007-06-07 change worked around this bug, but didn't fix it. * systime.h (tzname, timezone): Remove no-longer-used declarations. 2011-10-19 Eli Zaretskii * xdisp.c (start_display): If the character at POS is displayed via a display vector, reset IT->current.dpvec_index to zero. (try_window_reusing_current_matrix): If a line ends in a display vector or the next line starts in a display vector, continue redrawing the window even though the character position of start_row was reached. (Bug#9771, part 2) 2011-10-18 Chong Yidong * xdisp.c (get_next_display_element): Handle U+2010 and U+2011 with nobreak-char-display too. 2011-10-18 Eli Zaretskii Fix part 3 of bug#9771. * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1. (bidi_resolve_neutral): Don't enter the expensive loop looking for non-neutral characters if the current character is a paragraph separator (a.k.a. Newline). This avoids running the same expensive loop twice, once when we consume the preceding newline and the other time when the line actually needs to be displayed. Avoid the loop when we see neutrals on the base embedding level following a character whose directionality is the same as the paragraph's. This avoids running the expensive loop when a line ends in a long sequence of neutrals, like control characters. Add assertion against STRONG_AL type. Slightly rearrange code that determines the type of a neutral given the first non-neutral that follows it. (bidi_level_of_next_char): Set next_en_pos to zero when invalidating its info. 2011-10-17 Eli Zaretskii * xdisp.c (push_display_prop): Determine whether to record string or buffer position by IT->string, not by IT->method. Allow GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4) (move_it_vertically_backward): Don't look for character position immediately after the newline when in a continuation line. (Bug#9771, part 1) 2011-10-15 Martin Rudalics * window.c (coordinates_in_window): Rewrite and delabelize vertical border check. (Bug#5357) (Bug#9618) 2011-10-14 Stefan Monnier * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained errors in XSetWindowBorder (bug#9310). 2011-10-13 Dmitry Antipov * editfns.c (Fset_time_zone_rule): Replace free with xfree to avoid crash when xmalloc overrun checking is enabled. 2011-10-13 Eli Zaretskii * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect cursor motion with and arrow keys. * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as some callers set that themselves. 2011-10-12 Eli Zaretskii * xdisp.c (find_row_edges): Handle the case where ROW comes from a display string and the previous row comes from the same string and is empty. (Bug#9739) (Bug#9738) 2011-10-12 Stefan Monnier * doc.c (get_doc_string): Encode file name (bug#9735). 2011-10-12 Eli Zaretskii * bidi.c (bidi_level_of_next_char): * xdisp.c (get_visually_first_element): Remove old incorrect comments regarding the Unicode Line Separator character. * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR. 2011-10-12 Dmitry Antipov * alloc.c (Fgc_status): Do not access beyond zombies array boundary if nzombies > MAX_ZOMBIES. * alloc.c (dump_zombies): Add missing format specifier. 2011-10-12 Paul Eggert * xdisp.c (set_cursor_from_row): Simplify conditionals, to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow. * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff. Some packages use them to denote characters with modifiers. 2011-10-11 Andreas Schwab * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR) (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid matching a pp-number. Rename parameter var to var1. 2011-10-11 Stefan Monnier * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709). 2011-10-08 Glenn Morris * callint.c (Fcall_interactively): Give a more explicit error for the 'c' case with a non-character input. (Bug#8479) 2011-10-08 Eli Zaretskii * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left lines. (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L lines that are hscrolled on the left. * dispnew.c (buffer_posn_from_coords): Account for a possible presence of header-line. (Bug#4426) 2011-10-07 Stefan Monnier * buffer.c (syms_of_buffer) : Don't advertise functionality which we discourage or doesn't work. 2011-10-07 Paul Eggert * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__ or sizeof. __alignof__ gives the wrong answer on Fedora x86-64 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int; this makes Emacs dump core during garbage collection on rare occasions. sizeof is obviously inferior to offsetof here, so stick with offsetof. (GC_POINTER_ALIGNMENT): New macro. (mark_memory): Omit 3rd (offset) arg; caller changed. Don't assume EMACS_INT alignment is the same as pointer alignment. 2011-10-03 Stefan Monnier * keyboard.c (read_key_sequence_remapped): New var. (read_key_sequence): Compute remapping in the right buffer. (command_loop_1): Use read_key_sequence's remapping directly. 2011-10-02 Stefan Monnier * dired.c (file_name_completion): Don't expand file name. (Ffile_name_completion, Ffile_name_all_completions): Expand file name before checking file name handler. * minibuf.c (Finternal_complete_buffer): Only show internal buffers if they've been requested explicitly (bug#9591). 2011-10-01 Andreas Schwab * keymap.c (Fsingle_key_description): Use make_specified_string instead of build_string to build string from push_key_description. (Bug#5193) 2011-09-30 Paul Eggert * buffer.h (struct buffer): Use time_t, not int, for a time stamp. This fixes a Y2038 bug on 64-bit hosts. * buffer.c (reset_buffer): * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved) (Fclear_buffer_auto_save_failure): Use 0, not -1, to represent an unset failure time, since time_t might not be signed. Remove dependency on glibc malloc internals. * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move back here from lisp.h, but with their new implementations. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here. * charset.c (charset_table_init): New static var. (syms_of_charset): Use it instead of xmalloc. This removes a dependency on glibc malloc internals. See Eli Zaretskii's comment in . * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move back to alloc.c. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c. 2011-09-30 Jan Djärv * nsterm.m (windowDidResize): Call x_set_window_size only when ns_in_resize is true. Otherwise set pixelwidth/height and call change_frame_size (Bug#9628). 2011-09-30 Paul Eggert Port --enable-checking=all to Fedora 14 x86-64. * charset.c (syms_of_charset): Also account for glibc malloc's internal overhead when calculating the initial malloc maximum. Port --enable-checking=all to Fedora 14 x86. * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move to lisp.h. (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc) (overrun_check_realloc, overrun_check_free): Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t). That way, xmalloc returns a properly-aligned pointer even if XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened to align OK on typical 64-bit hosts, but not on Fedora 14 x86. * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD into account when calculating the initial malloc maximum. * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move here from alloc.c, so that charset.c can use it too. Properly align; the old code wasn't right for common 32-bit hosts when configured with --enable-checking=all. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): New macros. 2011-09-29 Eli Zaretskii * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined, use EDOM. 2011-09-28 Eli Zaretskii * xdisp.c (compute_display_string_end): If there's no display string at CHARPOS, return -1. * bidi.c (bidi_fetch_char): When compute_display_string_end returns a negative value, treat the character as a normal character not covered by a display string. (Bug#9624) 2011-09-28 Juanma Barranquero * lread.c (Fread_from_string): Fix typo in docstring. 2011-09-27 Eli Zaretskii * xdisp.c (handle_invisible_prop): If invisible text ends on a newline, reseat the iterator instead of bidi-iterating there one character at a time. (Bug#9610) (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past TO_CHARPOS if the bidi iterator is at base embedding level. 2011-09-27 Andreas Schwab * lread.c (readevalloop): Use correct code for NBSP. (read1): Likewise. (Bug#9608) 2011-09-25 Michael Albinus * dbusbind.c (Fdbus_register_signal): When service is not registered, use nil in Vdbus_registered_objects_table. (Bug#9581) 2011-09-25 Glenn Morris * buffer.c (truncate-lines): Doc fix. 2011-09-24 Chong Yidong * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers) (Fset_window_next_buffers): Doc fix. 2011-09-24 Glenn Morris * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715) 2011-09-24 Paul Eggert Fix minor problems found by static checking. * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int. * indent.c (Fvertical_motion): Fix == vs = typo. 2011-09-24 Eli Zaretskii * dispnew.c (syms_of_display) : Default value is now t. Doc fix. * indent.c (Fvertical_motion): Compute and apply the overshoot logic when moving up, not only when moving down. Fix the confusing name and values of the it_overshoot_expected variable; logic changes accordingly. (Bug#9254) (Bug#9549) * xdisp.c (pos_visible_p): Produce correct pixel coordinates when CHARPOS is covered by a display string which includes newlines. (move_it_vertically_backward): Avoid inflooping when START_CHARPOS is covered by a display string with embedded newlines. 2011-09-24 Michael Albinus * dbusbind.c (Fdbus_register_signal): Add match rule to Vdbus_registered_objects_table. (Bug#9581) (Fdbus_register_method, Vdbus_registered_objects_table): Fix docstring. 2011-09-24 Jim Meyering do not ignore write error for any output size The previous change was incomplete. While it makes emacs --batch detect the vast majority of stdout write failures, errors were still ignored whenever the output size is k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096, $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \ && echo FAIL: ignored write error FAIL: ignored write error $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \ && echo FAIL: ignored write error FAIL: ignored write error * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574) 2011-09-23 Andreas Schwab * emacs.c (Fkill_emacs): In noninteractive mode exit non-successfully if a write error occurred on stdout. (Bug#9574) 2011-09-21 Eli Zaretskii * xdisp.c (pop_it): Allow it->object that is a cons cell to pass the xassert test. * dispextern.h (struct it): Update the comment documenting what can it->OBJECT be. 2011-09-20 Eli Zaretskii * xdisp.c (set_cursor_from_row): If the row ends in a newline from a display string, extend search for cursor position to end of row. (find_row_edges): If the row ends in a newline from a display string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549) Handle the case of a display string with multiple newlines. (Fcurrent_bidi_paragraph_direction): Fix search for previous non-empty line. Fixes confusing cursor motion with arrow keys at the beginning of a line that starts with whitespace. 2011-09-19 Lars Magne Ingebrigtsen * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is (bug#9493). 2011-09-18 Chong Yidong * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as boolean (Bug#9154). 2011-09-18 Eli Zaretskii * xdisp.c (display_line): Record maximum and minimum buffer positions even if no glyphs were produced (e.g., by a zero-width stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record buffer positions that will be removed from the glyph row because they don't fit. (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the column is beyond frame width: don't subtract 1 "pixel" when computing width of the stretch. (reseat_at_next_visible_line_start): Undo the change made on 2011-09-17 that saved paragraph information and restored it after the call to `reseat'. (Bug#9545) 2011-09-18 YAMAMOTO Mitsuharu * xdisp.c (expose_window): Save original value of phys_cursor_on_p and turn window cursor on if cleared (Bug#9415). 2011-09-18 Andreas Schwab * search.c (boyer_moore): Take unibyte characters from pattern literally. (Bug#9458) 2011-09-18 Eli Zaretskii * xdisp.c (reseat_at_next_visible_line_start): Fix last change. 2011-09-18 Paul Eggert Fix minor problem found by static checking. * xdisp.c (reseat_at_next_visible_line_start): Mark locals as initialized, to pacify gcc -Wuninitialized. * fileio.c: Report proper errno when syscall falls. (Finsert_file_contents): Save and restore errno, so that report_file_error outputs the correct diagnostic. (Fwrite_region) [CLASH_DETECTION]: Likewise. 2011-09-18 Eli Zaretskii * .gdbinit (pgx): Fix references to fields of `struct glyph'. 2011-09-17 Eli Zaretskii * xdisp.c (produce_stretch_glyph): Another fix for changes made on 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530) 2011-09-17 Eli Zaretskii * xdisp.c (reseat_at_next_visible_line_start): Keep information about the current paragraph and restore it after the call to reseat. * bidi.c (MAX_PARAGRAPH_SEARCH): New macro. (bidi_find_paragraph_start): Search back for paragraph beginning at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE. (bidi_move_to_visually_next): Only trigger paragraph-related computations when the last character is a newline or at EOB, not just any NEUTRAL_B. (Bug#9470) * xdisp.c (set_cursor_from_row): Don't invoke special treatment of truncated lines if point is covered by a display string. (Bug#9524) 2011-09-16 Paul Eggert * xselect.c: Relax test for outgoing X longs (Bug#9498). (cons_to_x_long): New function. (lisp_data_to_selection_data): Use it. Correct the test for short-versus-long data; it was negated. Break out of vector loop, for efficiency, when a long datum is discovered. 2011-09-16 Stefan Monnier * eval.c (Fquote): Document its non-consing behavior (bug#9482). 2011-09-16 Eli Zaretskii * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see GCC PR/17406) by declaring this function with external scope. 2011-09-15 Paul Eggert * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514). Don't mishandle (length (format "%%")) and (format "%4000s%%" ""). 2011-09-15 Andreas Schwab * editfns.c (Fformat): Correctly handle text properties on "%%". 2011-09-15 Eli Zaretskii * xterm.c (x_draw_composite_glyph_string_foreground): * w32term.c (x_draw_composite_glyph_string_foreground): * term.c (encode_terminal_code): * composite.c (composition_update_it, get_composition_id): * xdisp.c (get_next_display_element) (fill_composite_glyph_string): Add comments about special meaning of TAB characters in a composition. 2011-09-15 Paul Eggert * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514). This occurs when processing a multibyte format. Problem reported by Wolfgang Jenker. 2011-09-15 Johan Bockgård * xdisp.c (try_cursor_movement): Only check for exact match if cursor hpos found by set_cursor_from_row is valid. (Bug#9495) 2011-09-14 Paul Eggert Remove unused external symbols. * dispextern.h (calc_pixel_width_or_height): Remove decl. * xdisp.c (calc_pixel_width_or_height): Now static. * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove. * indent.c (check_display_width): * w32term.c: Fix comment to match code. * xterm.c, xterm.h (x_catching_errors): Remove. 2011-09-14 Paul Eggert * xselect.c: Use signed conversions more consistently (Bug#9498). (selection_data_to_lisp_data): Assume incoming selection data are signed integers, not unsigned. This is to be consistent with outgoing selection data, which was modified to use signed integers in as part of the fix to Bug#9196 in response to Jan D.'s comment in that X11 expects long, not unsigned long. 2011-09-14 Eli Zaretskii * xdisp.c (try_window_reusing_current_matrix): Fix incorrect computation of loop end. Reported by Johan Bockgård . 2011-09-13 Chong Yidong * frame.c (Fother_visible_frames_p): Function deleted. 2011-09-12 Eli Zaretskii * indent.c (compute_motion): Process display vector front to back rather than the other way around.

(Bug#9475) 2011-09-11 Lars Magne Ingebrigtsen * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a value for non-existent files. 2011-09-11 Eli Zaretskii * fileio.c (Finsert_file_contents): If the file cannot be opened, set its "size" to -1. This will set the modtime_size field of the corresponding buffer to -1, which is what verify-visited-file-modtime expects for files that do not exist. (Bug#9139) 2011-09-11 Paul Eggert * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls here ... * lisp.h: ... from here. push_key_description is no longer defined in keyboard.c, so its declaration should not be in lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE logically belongs with push_key_description. 2011-09-10 Paul Eggert * buffer.h: Include instead of . Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386. Problem reported by Herbert J. Skuhra. 2011-09-10 Lars Magne Ingebrigtsen * xml.c (parse_region): Make the parsing work for non-comment-starting XML files again (bug#9144). 2011-09-10 Andreas Schwab * image.c (gif_load): Fix calculation of bottom and right corner. (Bug#9468) 2011-09-10 Eli Zaretskii * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish redisplay in small windows. 2011-09-09 Eli Zaretskii * frame.c (x_report_frame_params): Cast to avoid compiler warnings. 2011-09-08 Martin Rudalics * window.c (Fset_window_prev_buffers, Fset_window_next_buffers): Operate on live windows only. 2011-09-08 Juanma Barranquero * emacs.c (my_heap_start): #ifdef to avoid warnings when unused. 2011-09-07 Eli Zaretskii * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it only under bidi iteration. 2011-09-07 Jan Djärv * gtkutil.c (xg_make_tool_item): Insert comment about eventbox. 2011-09-06 Paul Eggert isnan: Fix porting problem to Solaris 10 with bundled gcc. Without this fix, the command to link temacs failed due to an undefined symbol __builtin_isnan. This is because /usr/include/iso/math_c99.h #defines isnan(x) to __builtin_isnan(x), but the bundled gcc, which identifies itself as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have a __builtin_isnan. * floatfns.c (isnan): #undef, and then #define to a clone of what's in data.c. (Fisnan): Always define, since it's always available now. (syms_of_floatfns): Always define isnan at the Lisp level. 2011-09-06 Paul Eggert * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169). 2011-09-06 Paul Eggert * fileio.c: Fix bugs with large file offsets (Bug#9428). The previous code assumed that file offsets (off_t values) fit in EMACS_INT variables, which is not true on typical 32-bit hosts. The code messed up by falsely reporting buffer overflow in cases such as (insert-file-contents "big" nil 1 2) into an empty buffer when "big" contains more than 2**29 bytes, even though this inserts just one byte and does not overflow the buffer. (Finsert_file_contents): Store file offsets as off_t values, not as EMACS_INT values. Check for overflow when converting between EMACS_INT and off_t. When checking for buffer overflow or for overlap, take the offsets into account. Don't use EMACS_INT for small values where int suffices. When checking for overlap, fix a typo: ZV was used where ZV_BYTE was intended. (Fwrite_region): Don't assume off_t fits into 'long'. * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT. 2011-09-05 Michael Albinus * dbusbind.c (xd_signature_cat): Rename from signature_cat. 2011-09-04 Paul Eggert sprintf-related integer and memory overflow issues (Bug#9412). * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values. (esprintf, exprintf, evxprintf): New functions. * keyboard.c (command_loop_level): Now EMACS_INT, not int. (cmd_error): Kbd macro iterations count is now EMACS_INT, not int. (modify_event_symbol): Do not assume that the length of name_alist_or_stem is safe to alloca and fits in int. (Fexecute_extended_command): Likewise for function name and binding. (Frecursion_depth): Wrap around reliably on integer overflow. * keymap.c (push_key_description): First arg is now EMACS_INT, not int, since some callers pass EMACS_INT values. (Fsingle_key_description): Don't crash if symbol name contains more than MAX_ALLOCA bytes. * minibuf.c (minibuf_level): Now EMACS_INT, not int. (get_minibuffer): Arg is now EMACS_INT, not int. * lisp.h (get_minibuffer, push_key_description): Reflect API changes. (esprintf, exprintf, evxprintf): New decls. * window.h (command_loop_level, minibuf_level): Reflect API changes. * dbusbind.c (signature_cat): New function. (xd_signature, Fdbus_register_signal): Do not overrun buffer; instead, report string overflow. * dispnew.c (add_window_display_history): Don't overrun buffer. Truncate instead; this is OK since it's just a log. * editfns.c (Fcurrent_time_zone): Don't overrun buffer even if the time zone offset is outlandishly large. Don't mishandle offset == INT_MIN. * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer when creating daemon; the previous buffer-overflow check was incorrect. * eval.c (verror): Simplify by rewriting in terms of evxprintf, which has the guts of the old verror function. * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name; use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues. * font.c: Include , for DBL_MAX_10_EXP. (font_unparse_xlfd): Don't blindly alloca long strings. Don't assume XINT result fits in int, or that XFLOAT_DATA * 10 fits in int, when using sprintf. Use single snprintf to count length of string rather than counting it via multiple sprintfs; that's simpler and more reliable. (font_unparse_fcname): Use it to avoid sprintf buffer overrun. (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not sprintf, in case result does not fit in int. * fontset.c (num_auto_fontsets): Now printmax_t, not int. (fontset_from_font): Print it. * frame.c (tty_frame_count): Now printmax_t, not int. (make_terminal_frame, set_term_frame_name): Print it. (x_report_frame_params): In X, window IDs are unsigned long, not signed long, so print them as unsigned. (validate_x_resource_name): Check for implausibly long names, and don't assume name length fits in 'int'. (x_get_resource_string): Don't blindly alloca invocation name; use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does not fit in int. * gtkutil.c: Include , for DBL_MAX_10_EXP. (xg_check_special_colors, xg_set_geometry): Make sprintf buffers a bit bigger, to avoid potential buffer overrun. * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does not fit in int. * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int. (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating it as a large positive number. (Fexecute_kbd_macro): Don't assume repeat count fits in int. * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int. * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf, in case result does not fit in int. * print.c (float_to_string): Detect width overflow more reliably. (print_object): Make sprintf buffer a bit bigger, to avoid potential buffer overrun. Don't assume list length fits in 'int'. Treat print length of 0 as 0, not as infinity; to be consistent with other uses of print length in this function. Don't overflow print length index. Don't assume hash table size fits in 'long', or that vectorlike size fits in 'unsigned long'. * process.c (make_process): Use printmax_t, not int, to format process-name gensyms. * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function. * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger to avoid potential buffer overrun. * xfaces.c (x_update_menu_appearance): Don't overrun buffer if X resource line is longer than 512 bytes. * xfns.c (x_window): Make sprintf buffer a bit bigger to avoid potential buffer overrun. * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer. * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF. 2011-09-04 Paul Eggert Integer overflow fixes for scrolling, etc. Without these, Emacs silently mishandles large integers sometimes. For example, "C-u 4294967297 M-x recenter" was treated as if it were "C-u 1 M-x recenter" on a typical 64-bit host. * xdisp.c (try_window_id): Check Emacs fixnum range before converting to 'int'. * window.c (window_scroll_line_based, Frecenter): Check that an Emacs fixnum is in range before assigning it to 'int'. (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for values converted from Emacs fixnums. (Frecenter): Don't wrap around a line count if it is out of 'int' range; instead, treat it as an extreme value. (Fset_window_configuration, compare_window_configurations): Use ptrdiff_t, not int, for index that might exceed 2 GiB. * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes that can exceed INT_MAX. Check that EMACS_INT value is in range before assigning it to the (possibly-narrower) index. (match_limit): Don't assume that a fixnum can fit in 'int'. * print.c (print_object): Use ptrdiff_t, not int, for index that can exceed INT_MAX. * indent.c (position_indentation): Now takes ptrdiff_t, not int. (Fvertical_motion): Don't wrap around LINES values that don't fit in 'int'. Instead, treat them as extreme values. This is good enough for windows, which can't have more than INT_MAX lines anyway. 2011-09-03 Lars Magne Ingebrigtsen * Require libxml/parser.h to avoid compilation warning. * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown. * xml.c (parse_region): Don't call xmlCleanupParser after parsing, since this reportedly can destroy thread storage. 2011-08-30 Chong Yidong * syntax.c (find_defun_start): Update all cache variables if exiting early (Bug#9401). 2011-08-30 Eli Zaretskii * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings. * xdisp.c (produce_stretch_glyph): No longer static, compiled also when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY frames. Call tty_append_glyph in the TTY case. (Bug#9402) * term.c (tty_append_glyph): New function. (produce_stretch_glyph): Static function and its prototype deleted. * dispextern.h (produce_stretch_glyph, tty_append_glyph): Add prototypes. 2011-08-29 Paul Eggert * image.c (parse_image_spec): Check for nonnegative, not for positive, when checking :margin (Bug#9390). (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR): Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR, so that the name doesn't mislead. All uses changed. 2011-08-28 Johan Bockgård * term.c (init_tty) [HAVE_GPM]: Move mouse settings after set_tty_hooks. 2011-08-27 Eli Zaretskii * xdisp.c (move_it_to): Don't bail out early when reaching position beyond to_charpos, if we are scanning backwards. (move_it_vertically_backward): When DY == 0, make sure we get to the first character in the line after the newline. 2011-08-27 Paul Eggert * ccl.c: Improve and simplify overflow checking (Bug#9196). (ccl_driver): Do not generate an out-of-range pointer. (Fccl_execute_on_string): Remove unnecessary check for integer overflow, noted by Stefan Monnier in . Remove a FIXME that didn't need fixing. Simplify the newly-introduced buffer reallocation code. 2011-08-27 Juanma Barranquero * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h. 2011-08-26 Paul Eggert Integer and memory overflow issues (Bug#9196). * doc.c (get_doc_string): Rework so that get_doc_string_buffer_size is the actual buffer size, rather than being 1 less than the actual buffer size; this makes xpalloc more convenient. * image.c (x_allocate_bitmap_record, cache_image): * xselect.c (Fx_register_dnd_atom): Simplify previous changes by using xpalloc. * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT, since either will do and ptrdiff_t is convenient with xpalloc. * charset.c (charset_table_size) (struct charset_sort_data.priority): Now ptrdiff_t. (charset_compare): Don't overflow if priorities differ greatly. (Fsort_charsets): Don't assume list length fits in int. Check for size-calculation overflow when allocating sort data. (syms_of_charset): Allocate an initial charset table that is just under 64 KiB, to avoid problems with glibc malloc and mmap. * cmds.c (internal_self_insert): Check for size-calculation overflow. * composite.h (struct composition.glyph_len): Now int, not unsigned. The actual value is always <= INT_MAX, and leaving it unsigned made overflow checking harder. * dispextern.h (struct glyph_matrix.rows_allocated) (struct face_cache.size): Now ptrdiff_t, for convenience in use with xpalloc. The values are still always <= INT_MAX. * indent.c (compute_motion): Adjust to region_cache_forward sig change. * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls. (SAFE_NALLOCA): New macro. * region-cache.c (struct boundary.pos, find_cache_boundary) (move_cache_gap, insert_cache_boundary, delete_cache_boundaries) (set_cache_region, invalidate_region_cache) (revalidate_region_cache, know_region_cache, region_cache_forward) (region_cache_backward, pp_cache): Use ptrdiff_t, not EMACS_INT, since either will do. This is needed so that ptrdiff_t * can be passed to xpalloc. (struct region_cache): Similarly, for gap_start, gap_len, cache_len, beg_unchanged, end_unchanged, buffer_beg, buffer_end members. (pp_cache): Don't assume cache_len fits in int. * region-cache.h: Adjust extern decls to match. * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not EMACS_INT, since either will do, for xpalloc. * alloc.c: Include verify.h, and check that int fits in ptrdiff_t. (xnmalloc, xnrealloc, xpalloc): New functions. * bidi.c (bidi_shelve_header_size): New constant. (bidi_cache_ensure_space, bidi_shelve_cache): Use it. (bidi_cache_ensure_space): Avoid integer overflow when allocating. * bidi.c (bidi_cache_shrink): * buffer.c (overlays_at, overlays_in, record_overlay_string) (overlay_strings): Don't update size of array until after memory allocation succeeds, because xmalloc/xrealloc may not return. (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help now that we have proper integer overflow checking. (record_overlay_string, overlay_strings): Catch overflows when calculating size of overlay_str_buf. * callproc.c (Fcall_process): Check for size overflow when calculating size of args2. (child_setup): Avoid overflow by using size_t rather than ptrdiff_t. Normally we prefer signed values, but sticking with ptrdiff_t would require adding more-complicated checks. * ccl.c (Fccl_execute_on_string): Check for memory overflow. Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do. Redo buffer-overflow calculations to avoid integer overflow. Add a FIXME comment where memory seems to be over-allocated. * character.c (Fstring): Check for size-calculation overflow. * coding.c (produce_chars): Redo buffer-overflow calculations to avoid unnecessary integer overflow. Check for size overflow. (encode_coding_object): Don't update size until xmalloc succeeds. * composite.c (get_composition_id): Check for overflow in glyph length calculations. Integer and memory overflow fixes for display code. * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int. * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool) (scrolling_window): Check for overflow in size calculations.

(Fmessage_box): Don't update size until allocation succeeds. Don't assume message length fits in int. (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do. * emacs.c (main): Do not reallocate argv, since there is a null at the end that can be overwritten, and this way there's no need to worry about size-calculation overflow. (sort_args): Check for size-calculation overflow. * eval.c (init_eval_once, grow_specpdl): Don't update size until alloc succeeds. (call_debugger, grow_specpdl): Redo calculations to avoid overflow. * frame.c (set_menu_bar_lines, x_set_frame_parameters) (x_set_scroll_bar_width, x_figure_window_size): Check for integer overflow. (x_set_alpha): Do not assume XINT fits in int. * frame.h (struct frame): Use int, not EMACS_INT, where int works. This is for the members text_lines, text_cols, total_lines, total_cols, where the system imposes an 'int' limit. * fringe.c (Fdefine_fringe_bitmap): Don't update size until alloc works. * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring) (ftfont_shape_by_flt): Check for integer overflow in size calculations. * gtkutil.c (get_utf8_string, xg_store_widget_in_map): Check for size-calculation overflow. (get_utf8_string): Use ptrdiff_t, not size_t, where either will do, as we prefer signed integers. (id_to_widget.max_size, id_to_widget.used) (xg_store_widget_in_map, xg_remove_widget_from_map) (xg_get_widget_from_map, xg_get_scroll_id_for_window) (xg_remove_scroll_bar, xg_update_scrollbar_pos): Use and return ptrdiff_t, not int. (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int. * gtkutil.h: Change prototypes to match the above. * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these are duplicate now that they've been promoted to lisp.h. (x_allocate_bitmap_record, x_alloc_image_color) (make_image_cache, cache_image, xpm_load): Don't update size until alloc is done. (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors) (x_detect_edges): Check for size calculation overflow. (ct_colors_allocated_max): New constant.

Redo size calculations to avoid overflow. Check for size calculation overflow. (main) [DEBUG]: Fix typo in invoking tparam1. * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title): Use ptrdiff_t, not int, for sizes. (store_mode_line_noprop_char): Don't update size until alloc done. * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face): Use ptrdiff_t, not int, for sizes. (Finternal_make_lisp_face, cache_face): Check for size calculation overflow.

Use them to make the following changes clearer. (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer. This change doesn't affect the value now, but it may help remind future maintainers not to raise the value too much later. (SELECTION_QUANTUM): Remove, replacing with ... (selection_quantum): ... new function, which avoids overflow. All uses changed. (struct selection_data.size): Now ptrdiff_t, not int, to avoid assumption that selection length fits in 'int'. (x_reply_selection_request, x_handle_selection_request) (x_get_window_property, receive_incremental_selection) (x_get_window_property_as_lisp_data, selection_data_to_lisp_data) (lisp_data_to_selection_data, clean_local_selection_data): Use ptrdiff_t, not int, to record length of selection. (x_reply_selection_request, x_get_window_property) (receive_incremental_selection, x_property_data_to_lisp): Redo calculations to avoid overflow.

(x_get_window_property, receive_incremental_selection) (lisp_data_to_selection_data, Fx_register_dnd_atom): Don't store size until memory allocation succeeds. (x_get_window_property): Plug memory leak on memory exhaustion. Don't double-block input; malloc is safe here. Don't assume 2**34 - 4 fits in unsigned long. Add an xassert to check XGetWindowProperty overflow. Be more careful about overflow calculations, and distinguish size from memory overflow better.

(x_selection_data_to_lisp_data): Remove unnecessary (and in theory harmful) conversions of unsigned short to int. (lisp_data_to_selection_data): Don't assume that integers in the range -65535 through -1 fit in an X unsigned short. Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into result parameters unless successful. Rely on cons_to_unsigned to report problems with elements; the old code wasn't right anyway.

(read_hex, load_charset_map_from_file): Check for integer overflow. * xterm.c: Don't go over XClientMessageEvent limit. (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed. (x_send_scroll_bar_event): Likewise. Check that the size does not exceed limits imposed by XClientMessageEvent, as well as the usual ptrdiff_t and size_t limits. * keyboard.c: Overflow, signedness and related fixes. (make_lispy_movement): Use same integer type in forward decl that is used in the definition. (read_key_sequence, keyremap_step): Change bufsize argument back to int, undoing my 2011-03-30 change. We prefer signed types, and int is wide enough here. (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string length, not size_t. Use ptrdiff_t for index, not int.

(x_bitmap_pixmap, x_create_x_image_and_pixmap): Omit unnecessary casts to int. (parse_image_spec): Check that integers fall into 'int' range when the callers expect that. (image_ascent): Redo ascent calculation to avoid int overflow. (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages. (lookup_image): Remove unnecessary tests. (xbm_image_p): Locals are now of int, not EMACS_INT, since parse_image_check makes sure they fit into int. (png_load, gif_load, svg_load_image): Prefer int to unsigned where either will do. (tiff_handler): New function, combining the cores of the old tiff_error_handler and tiff_warning_handler. This function is rewritten to use vsnprintf and thereby avoid stack buffer overflows. It uses only the features of vsnprintf that are common to both POSIX and native Microsoft. (tiff_error_handler, tiff_warning_handler): Use it. (tiff_load, gif_load, imagemagick_load_image): Don't assume :index value fits in 'int'. (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

Check for integer overflow when computing image height and width. 2011-08-26 Eli Zaretskii * xdisp.c (redisplay_window): Don't force window start if point will be invisible in the resulting window. (Bug#9324) 2011-08-25 Eli Zaretskii * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when the display spec is of the form `(space ...)'. (handle_display_spec): Return the value returned by handle_single_display_spec, not just 1 or zero. (handle_single_display_spec): If the display spec is of the form `(space ...)', and specifies display in the text area, return 2 rather than 1. (try_cursor_movement): Check for the need to scroll more accurately, and prefer exact match for point under bidi. Don't advance `row' beyond the last row of the window. * dispextern.h (struct bidi_it): Rename the disp_prop_p member into disp_prop; all users changed. * bidi.c (bidi_fetch_char): If compute_display_string_pos returns DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character for the text covered by the display property. 2011-08-25 Chong Yidong * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer. Change return value to nil. (Frecord_buffer): Delete unused function. 2011-08-24 Eli Zaretskii * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte buffers, return left-to-right.

Fixes cursor positioning on the newline at EOL of R2L text within L2R paragraph, and vice versa. (try_cursor_movement): Check continued rows, in addition to continuation rows. Fixes unwarranted scroll when point enters a continued line of R2L text within an L2R paragraph, or vice versa. (cursor_row_p): Consider the case of point being equal to MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving from the end of a short line to the beginning of a continued line of R2L text within L2R paragraph. (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for composed characters. * bidi.c (bidi_check_type): Use xassert.

(Bug#8874) * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos instead of CHAR_TO_BYTE. Fixes a crash when a completion candidate is selected by the mouse, and that candidate has a composed character under the mouse. * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel coordinates reported by pos-visible-in-window-p for a composed character in column zero. 2011-08-23 Stefan Monnier * cmds.c (Fself_insert_command): Mention post-self-insert-hook. 2011-08-22 Eli Zaretskii * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition, consider it a hit if to_charpos is anywhere in the range of the composed buffer positions. 2011-08-22 Chong Yidong * image.c (gif_load): Don't assume that each subimage has the same dimensions as the base image. Handle disposal method that is "undefined" by the gif spec (Bug#9335). 2011-08-20 Chong Yidong * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329). (Fcondition_case): Document `debug' symbol in error handler. 2011-08-19 Eli Zaretskii * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of face ID by FACE_FROM_ID, and avoid a crash when mouse is moved from an Org mode buffer to a Speedbar frame. * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from a composition, take its buffer position from IT->cmp_it.charpos. Fixes cursor positioning at the beginning of a line that begins with a composed character. 2011-08-18 Eli Zaretskii * bidi.c (bidi_get_type): If bidi_type_table reports zero as the character bidirectional type, use STRONG_L instead. Fixes crashes in a buffer produced by `describe-categories'. * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p members before the level stack, so they would be saved and restored when copying iterator state. Fixes incorrect reordering around TABs covered by display properties. 2011-08-18 Andreas Schwab * process.c (Fnetwork_interface_list): Correctly determine buffer size. 2011-08-17 Chong Yidong * eval.c (internal_condition_case, internal_condition_case_1) (internal_condition_case_2, internal_condition_case_n): Remove unnecessary aborts (Bug#9081). 2011-08-17 Eli Zaretskii * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file has no `load' handler, try opening the file locally.

Fixes vertical cursor motion when line beginning is covered by an image. (Bug#9296) 2011-08-14 Jan Djärv * nsterm.h (ns_run_ascript): Declare. (NSAPP_DATA2_RUNASSCRIPT): Define. * nsfns.m (as_script, as_result, as_status): New static variables. (ns_run_ascript): New function. (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start the event loop. Get status from as_status (Bug#7276). * nsterm.m (sendEvent): If event is NSApplicationDefined and data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit the event loop (Bug#7276). 2011-08-14 Andreas Schwab * gnutls.c (QCgnutls_bootprop_priority) (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist) (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks) (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname) (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags) (QCgnutls_bootprop_verify_hostname_error) (QCgnutls_bootprop_callbacks_verify): Rename from Qgnutls_bootprop_..., all uses changed. * xfaces.c (QCignore_defface): Rename from Qignore_defface, all uses changed. 2011-08-14 Paul Eggert * xfaces.c (Qframe_set_background_mode): Now static. * dispextern.h (Qframe_set_background_mode): Remove decl. * process.c (Fnetwork_interface_info): Declare local only if needed. 2011-08-13 Jan Djärv * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477). (Fnetwork_interface_list): Allocate in increments of bytes instead of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct sockaddr. (struct ifflag_def): notrailers is smart on OSX. (Fnetwork_interface_info): Handle case when ifr_flags is negative. Get hardware address with getifaddrs if available. 2011-08-12 Eli Zaretskii * xdisp.c (iterate_out_of_display_property): xassert that IT->position is set to within IT->object's boundaries. Break from the loop as soon as EOB is reached; avoids infloops in redisplay when IT->position is set up wrongly due to some bug. Set IT->current to match the bidi iterator unconditionally. (push_display_prop): Allow GET_FROM_STRING as IT->method on entry. Force push_it to save on the stack the current buffer/string position, to be restored by pop_it. Fix flags in the iterator structure wrt the object coming from a display property, as `line-prefix' and `wrap-prefix' are not ``replacing'' properties. (Bug#9284) 2011-08-09 Andreas Schwab * fontset.c (fontset_get_font_group): Add proper type checks. (Bug#9172) 2011-08-09 YAMAMOTO Mitsuharu * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS and LC_VERSION_MIN_MACOSX. (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function. (dump_it) [LC_FUNCTION_STARTS]: Use it. 2011-08-08 Eli Zaretskii * xdisp.c (forward_to_next_line_start): Allow to use the no-display-properties-and-no-overlays under bidi display. Set disp_pos in the bidi iterator to avoid searches for display properties and overlays. 2011-08-08 Chong Yidong * editfns.c (Fset_time_zone_rule): Document relationship with the setenv function. * ftfont.c (ftfont_pattern_entity): Copy the extras argument to the font entity extracted from the cache (Bug#8109). 2011-08-07 Chong Yidong * composite.c (autocmp_chars): Don't reset point. That is done by restore_point_unwind (Bug#5984). 2011-08-07 Juri Linkov * editfns.c (Fformat_time_string): Doc fix, add tag `usage:' to show the arg `TIME' instead of `TIMEVAL'. 2011-08-06 Eli Zaretskii * xdisp.c (set_cursor_from_row): Fix cursor positioning when a display property strides EOL and includes a newline, as in longlines-mode. (Bug#9254) (move_it_in_display_line_to): Fix vertical-motion in a buffer with word-wrap under bidirectional display. (Bug#9224) * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE is non-zero, even if the data buffer is NULL. Fixes a crash in vertical-motion with longlines-mode. (Bug#9254) 2011-08-05 Eli Zaretskii * bidi.c : Now static. (bidi_initialize): Initialize bidi_cache_total_alloc. * xdisp.c (display_line): Release buffer allocated for shelved bidi cache. (Bug#9221) * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total amount allocated this far in `bidi_cache_total_alloc'. (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if non-zero, only free the data buffer without restoring the cache contents. All callers changed. * dispextern.h (bidi_unshelve_cache): Update prototype. * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to) (move_it_in_display_line, move_it_to) (move_it_vertically_backward, move_it_by_lines): Replace the call to xfree to an equivalent call to bidi_unshelve_cache. (move_it_in_display_line_to): Fix logic of returning MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224) 2011-08-05 Eli Zaretskii * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that came from a string character with a `cursor' property. (Bug#9229) 2011-08-04 Jan Djärv * Makefile.in (LIB_PTHREAD): New variable. (LIBES): Add LIB_PTHREAD (Bug#9216). * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h: Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216). 2011-08-04 Andreas Schwab * regex.c (re_iswctype): Remove some redundant boolean conversions. 2011-08-04 Jan Djärv * xterm.c (x_find_topmost_parent): New function.

(handle_one_xevent): Call x_set_frame_alpha on ReparentNotify. 2011-08-04 Paul Eggert * callproc.c (Fcall_process): Avoid vfork clobbering the local vars buffer, coding_systems, current_dir. 2011-08-03 Stefan Monnier * keymap.c (Fmake_composed_keymap): Move to subr.el. 2011-08-03 Paul Eggert * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE so that it is not optimized away. * xdisp.c (compute_display_string_pos): Remove unused local. 2011-08-02 Eli Zaretskii Fix slow cursor motion and scrolling in large buffers with selective display, like Org Mode buffers. (Bug#9218) * dispextern.h (struct bidi_it): New member disp_prop_p. * xdisp.c: Remove one-slot cache of display string positions. (compute_display_string_pos): Accept an additional argument DISP_PROP_P; callers changed. Scan at most 5K characters forward for a display string or property. If found, set DISP_PROP_P non-zero. * bidi.c (bidi_fetch_char): Accept an additional argument DISP_PROP_P, and pass it to compute_display_string_pos. Only handle text covered by a display string if DISP_PROP_P is returned non-zero. All callers of bidi_fetch_char changed. 2011-08-02 Stefan Monnier * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE. 2010-12-03 Don March * keymap.c (Fdefine_key): Fix non-prefix key error message when last character M-[char] is translated to ESC [char] (bug#7541). 2011-08-02 Kenichi Handa * lisp.h (uniprop_table): Extern it. * chartab.c (uniprop_table): Make it non-static. 2011-08-01 Eli Zaretskii * xdisp.c (forward_to_next_line_start): Accept additional argument BIDI_IT_PREV, and store into it the state of the bidi iterator had on the newline. (reseat_at_next_visible_line_start): Use the bidi iterator state returned by forward_to_next_line_start to restore the state of it->bidi_it after backing up to previous newline. (Bug#9212) 2011-07-30 Andreas Schwab * regex.c (re_comp): Protoize. (re_exec): Fix return type. (regexec): Fix type of `ret'. (Bug#9203) 2011-07-28 Paul Eggert * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189). This is needed if max-image-size is a floating-point number. 2011-07-28 Andreas Schwab * print.c (print_object): Print empty symbol as ##. * lread.c (read1): Read ## as empty symbol. 2011-07-28 Alp Aker * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when setting frame foreground color (Bug#9175). (x_set_background_color): Likewise. * nsmenu.m (-setText): Size tooltip dimensions precisely to contents (Bug#9176).

Change treatment of cursor drawing to accommodate underlining, etc. 2011-07-28 Eli Zaretskii * buffer.c (init_buffer_once): Set bidi-display-reordering to t by default. 2011-07-28 Paul Eggert * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race. Without this fix, if a signal arrives just after memory fills up, 'malloc' might be invoked reentrantly. * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1. In other words, assume that every image size is allowed, on non-X hosts. This assumption is probably wrong, but it lets Emacs compile. 2011-07-28 Andreas Schwab * regex.c (re_iswctype): Convert return values to boolean. 2011-07-28 Eli Zaretskii * xdisp.c (compute_display_string_pos): Don't use cached display string position if the buffer had its restriction changed. (Bug#9184) 2011-07-28 Paul Eggert * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering. 2011-07-28 Paul Eggert Integer signedness and overflow and related fixes.

(bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx) (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search) (bidi_cache_find_level_change, bidi_cache_ensure_space) (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack) (bidi_find_other_level_edge): Use ptrdiff_t instead of EMACS_INT where either will do. This works better on 32-bit hosts configured --with-wide-int. (bidi_cache_ensure_space): Check for size-calculation overflow. Use % rather than repeated addition, for better worst-case speed. Don't set bidi_cache_size until after xrealloc returns, because it might not return. (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow. (bidi_cache_ensure_space): Also check that the bidi cache size does not exceed that of the largest Lisp string or buffer. See Eli Zaretskii in . * alloc.c (__malloc_size_t): Remove. All uses replaced by size_t. See Andreas Schwab's note . * image.c: Improve checking for integer overflow. (check_image_size): Assume that f is nonnull, since it is always nonnull in practice. This is one less thing to worry about when checking for integer overflow later. (x_check_image_size): New function, which checks for integer overflow issues inside X. (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it. This removes the need for a memory_full check. (xbm_image_p): Rewrite to avoid integer multiplication overflow. (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size. (xbm_read_bitmap_data): Change locals back to 'int', since their values must fit in 'int'. (xpm_load_image, png_load, tiff_load): Invoke x_create_x_image_and_pixmap earlier, to avoid much needless work if the image is too large. (tiff_load): Treat overly large images as if x_create_x_image_and_pixmap failed, not as malloc failures. (gs_load): Use x_check_image_size. * gtkutil.c: Omit integer casts. (xg_get_pixbuf_from_pixmap): Remove unnecessary cast. (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast. * image.c (png_load): Don't assume height * row_bytes fits in 'int'. * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug. Without this fix, (bitmap-spec-p '(34359738368 1 "x")) would wrongly return t on a 64-bit host. * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros. The plain *_OVERFLOW macros run afoul of GCC bug 49705 and therefore cause GCC to emit a bogus diagnostic in some cases. * image.c: Integer signedness and overflow and related fixes. This is not an exhaustive set of fixes, but it's time to record what I've got. (lookup_pixel_color, check_image_size): Remove redundant decls. (check_image_size): Don't assume that arbitrary EMACS_INT values fit in 'int', or that arbitrary 'double' values fit in 'int'.

(x_create_x_image_and_pixmap): Remove unnecessary test for xmalloc returning NULL; that can't happen. (xbm_read_bitmap_data): Don't assume sizes fit into 'int'. (xpm_color_bucket): Use better integer hashing function. (xpm_cache_color): Don't possibly over-allocate memory. (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory) (gif_memory_source): Use ptrdiff_t, not int or size_t, to record sizes. (png_load): Don't assume values greater than 2**31 fit in 'int'. (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when either works, as we prefer signed integers. (tiff_read_from_memory, tiff_write_from_memory): Return tsize_t, not size_t, since that's what the TIFF API wants. (tiff_read_from_memory): Don't fail simply because the read would go past EOF; instead, return a short read. (tiff_load): Omit no-longer-needed casts. (Fimagemagick_types): Don't assume size fits into 'int'. Improve hashing quality when configured --with-wide-int. * fns.c (hash_string): New function, taken from sxhash_string. Do not discard information about ASCII character case; this discarding is no longer needed. (sxhash-string): Use it. Change sig to match it. Caller changed. * lisp.h: Declare it. * lread.c (hash_string): Remove, since we now use fns.c's version. The fns.c version returns a wider integer if --with-wide-int is specified, so this should help the quality of the hashing a bit. * emacs.c: Integer overflow minor fix. (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed. Define only if GNU_LINUX. (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX. * dispnew.c: Integer signedness and overflow fixes. Remove unnecessary forward decls, that were a maintenance hassle. (history_tick): Now uprintmax_t, so it's more likely to avoid overflow. All uses changed. (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer) (scrolling_window): Use ptrdiff_t, not int, for byte count. (prepare_desired_row, line_draw_cost): Use int, not unsigned, where either works. (save_current_matrix, restore_current_matrix): Use ptrdiff_t, not size_t, where either works. (init_display): Check for overflow more accurately, and without relying on undefined behavior. * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide): Remove, replacing with the new symbols in lisp.h. All uses changed. * fileio.c (make_temp_name): * filelock.c (lock_file_1, lock_file): * xdisp.c (message_dolog): Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts. Use pMd etc. instead. * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros, replacing the pWIDE etc. symbols removed from editfns.c. * keyboard.h (num_input_events): Now uintmax_t. This is (very slightly) less likely to mess up due to wraparound. All uses changed. * buffer.c: Integer signedness fixes. (alloc_buffer_text, enlarge_buffer_text): Use ptrdiff_t rather than size_t when either will do, as we prefer signed integers. * alloc.c: Integer signedness and overflow fixes. Do not impose an arbitrary 32-bit limit on malloc sizes when debugging. (__malloc_size_t): Default to size_t, not to int. (pure_size, pure_bytes_used_before_overflow, stack_copy_size) (Fgarbage_collect, mark_object_loop_halt, mark_object): Prefer ptrdiff_t to size_t when either would do, as we prefer signed integers. (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro. (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer): Now const. Initialize with values that are in range even if char is signed. (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ... (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed. These functions do the right thing with sizes > 2**32. (check_depth): Now ptrdiff_t, not int. (overrun_check_malloc, overrun_check_realloc, overrun_check_free): Adjust to new way of storing sizes. Check for size overflow bugs in rest of code. (STRING_BYTES_MAX): Adjust to new overheads. The old code was slightly wrong anyway, as it missed one instance of XMALLOC_OVERRUN_CHECK_OVERHEAD. (refill_memory_reserve): Omit needless cast to size_t. (mark_object_loop_halt): Mark as externally visible. * xselect.c: Integer signedness and overflow fixes. (Fx_register_dnd_atom, x_handle_dnd_message): Use ptrdiff_t, not size_t, since we prefer signed. (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow. * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for x_dnd_atoms_size and x_dnd_atoms_length. * doprnt.c: Prefer signed to unsigned when either works. * eval.c (verror): * doprnt.c (doprnt): * lisp.h (doprnt): * xdisp.c (vmessage): Use ptrdiff_t, not size_t, when using or implementing doprnt, since the sizes cannot exceed ptrdiff_t bounds anyway, and we prefer signed arithmetic to avoid comparison confusion. * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow, but is a bit tricky. Assume freestanding C89 headers, string.h, stdlib.h. * data.c, doprnt.c, floatfns.c, print.c: Include float.h unconditionally. * gmalloc.c: Assume C89-at-least behavior for preprocessor, limits.h, stddef.h, string.h.

(__malloc_safe_bcopy): Remove; no longer needed. * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes. Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally well either way, and we prefer signed to unsigned. 2011-07-27 Lars Magne Ingebrigtsen * gnutls.c (emacs_gnutls_read): Don't message anything if the peer closes the connection while we're reading (bug#9182). 2011-07-25 Jan Djärv * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons are specified (Bug#9168). 2011-07-25 Paul Eggert * bidi.c (bidi_dump_cached_states): Fix printf format mismatch. Found by GCC static checking and --with-wide-int on a 32-bit host. 2011-07-25 Eli Zaretskii * xdisp.c (compute_display_string_pos): Fix logic of caching previous display string position.

Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay when exact match is impossible due to invisible text, and the lines are truncated. 2011-07-23 Jan Djärv * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask for OSX >= 10.7. 2011-07-22 Eli Zaretskii Fix a significant slow-down of cursor motion with C-n, C-p, C-f/C-b, and C-v/M-v that couldn't keep up with keyboard auto-repeat under bidi redisplay in fontified buffers. * xdisp.c (compute_stop_pos_backwards): New function. (next_element_from_buffer): Call compute_stop_pos_backwards to find a suitable prev_stop when we find ourselves before base_level_stop. (reseat): Don't look for prev_stop, as that could mean a very long run. : Cache for last found display string position. (compute_display_string_pos): Return the cached position if asked about the same buffer in the same area of character positions, and the buffer wasn't changed since the time the display string position was cached. 2011-07-22 Eli Zaretskii * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object is an integer, which is important for empty lines. (Bug#9149) 2011-07-22 Chong Yidong * frame.c (Fmodify_frame_parameters): In tty case, update the default face if necessary (Bug#4238). 2011-07-21 Chong Yidong * editfns.c (Fstring_to_char): No need to explain what a character is in the docstring (Bug#6576). 2011-07-20 Lars Magne Ingebrigtsen * xml.c (parse_region): Make sure we always return a tree. 2011-07-20 HAMANO Kiyoto * xml.c (parse_region): If a document contains only comments, return that, too. 2011-07-20 Lars Magne Ingebrigtsen * xml.c (make_dom): Return comments, too. 2011-07-19 Paul Eggert Port to OpenBSD. See https://lists.gnu.org/r/emacs-devel/2011-07/msg00688.html and the surrounding thread. * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar rather than fgets, and retry after EINTR.

This fixes some race conditions on the permissions of any newly created file. * alloc.c (valid_pointer_p): Use pipe, not open. This fixes some permissions issues when debugging. * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002) If fchown fails to set both uid and gid, try to set just gid, as that is sometimes allowed. Adjust the file's mode to eliminate setuid or setgid bits that are inappropriate if fchown fails. 2011-07-18 Stefan Monnier * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ to compare Lisp_Objects. * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to global_gnutls_log_level, don't mistake it for a Lisp_Object. (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses. 2011-07-17 Andreas Schwab * lread.c (read_integer): Unread even EOF character. (read1): Likewise. Properly record start position of symbol. * lread.c (read1): Read `#:' as empty uninterned symbol if no symbol character follows. 2011-07-17 Paul Eggert * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002) This works around a problem with the previous change to Fcopy_file. Recent glibc declares fchown with __attribute__((warn_unused_result)), and without this change, GCC might complain about discarding fchown's return value. 2011-07-16 Juanma Barranquero * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059). 2011-07-16 Paul Eggert * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002) 2011-07-16 Lars Magne Ingebrigtsen * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since it's used from the C level. * process.c: Use the same condition for POLL_FOR_INPUT in both keyboard.c and process.c (bug#1858). 2011-07-09 Lawrence Mitchell * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.

(elsz): Now a signed constant, not a size_t var. We prefer signed types to unsigned, to avoid integer comparison confusion. Without this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains "cannot optimize loop, the loop counter may overflow", a symptom of the confusion. * indent.c (Fvertical_motion): Mark locals as initialized. * xdisp.c (reseat_to_string): Fix pointer signedness issue. 2011-07-14 Lars Magne Ingebrigtsen * search.c (Fre_search_backward): Mention `case-fold-search' in all the re_search_* functions (bug#8138). * keyboard.c (Fopen_dribble_file): Document when the file is closed (bug#8056). 2011-07-14 Eli Zaretskii * bidi.c (bidi_dump_cached_states): Fix format of displaying bidi_cache_idx.

(init_iterator): Call bidi_init_it only of a valid buffer position was specified. Initialize paragraph_embedding to L2R. (reseat_to_string): Initialize the bidi iterator. (display_string): If we need to ignore text properties of LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The original value of -1 will not work with bidi.)

(compute_display_string_end): Support display properties on Lisp strings. (init_iterator, reseat_1, reseat_to_string): Initialize the string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS when iterating on a string not from display properties). (compute_display_string_pos, compute_display_string_end): Fix calculation of the object to scan. Fixes an error when using arrow keys. (next_element_from_buffer): Don't abort when IT_CHARPOS is before base_level_stop; instead, set base_level_stop to BEGV. Fixes crashes in vertical-motion. (next_element_from_buffer): Improve commentary for when the iterator is before prev_stop. (init_iterator): Initialize bidi_p from the default value of bidi-display-reordering, not from buffer-local value. Use the buffer-local value only if initializing for buffer iteration.

(face_before_or_after_it_pos): Support bidi iteration. (next_element_from_c_string): Handle the case of the first string character that is not the first one in the visual order. (get_visually_first_element): New function, refactored from common parts of next_element_from_buffer, next_element_from_string, and next_element_from_c_string. (tool_bar_lines_needed, redisplay_tool_bar) (display_menu_bar): Force left-to-right direction. Add a FIXME comment for making that be controlled by a user option.

(forward_to_next_line_start): Don't use the shortcut if bidi-iterating. (back_to_previous_visible_line_start): If handle_display_prop pushed the iterator stack, restore the internal state of the bidi iterator by calling bidi_pop_it same number of times. (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero, and we are bidi-iterating, don't decrement the iterator position; instead, set the first_elt flag in the bidi iterator, to produce the same effect. (reseat_1): Remove redundant setting of string_from_display_prop_p. (push_display_prop): xassert that we are iterating a buffer. (push_it, pop_it): Save and restore paragraph_embedding member. (handle_single_display_spec, next_overlay_string) (get_overlay_strings_1, reseat_1, reseat_to_string) (push_display_prop): Set up the `unibyte' member of bidi_it.string correctly. Don't assume unibyte strings are not bidi-reordered. (compute_display_string_pos) (compute_display_string_end): Fix handling the case of C string. (push_it, pop_it): Save and restore from_disp_prop_p. (handle_single_display_spec, push_display_prop): Set the from_disp_prop_p flag. (get_overlay_strings_1): Reset the from_disp_prop_p flag.

(back_to_previous_visible_line_start, reseat_1) (init_iterator): Empty the bidi cache "stack". (move_it_in_display_line_to): If iterator ended up at EOL, but we never saw any buffer positions smaller than to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor motion in bidi-reordered lines. (move_it_in_display_line_to): Record prev_method and prev_pos immediately before the call to set_iterator_to_next. Fixes cursor motion in bidi-reordered lines with stretch glyphs and strings displayed in margins. (Bug#8133) (Bug#8867) Return MOVE_POS_MATCH_OR_ZV only if iterator position is past TO_CHARPOS. (pos_visible_p): Support positions in bidi-reordered lines. Save and restore bidi cache. * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

The old code sometimes used this field without initializing it. * alloc.c (gc_sweep): Don't read past end of array. In theory, the old code could also have corrupted Emacs internals, though it'd be very unlikely. 2011-07-12 Andreas Schwab * character.c (Fcharacterp): Don't advertise optional ignored argument.

E.g., (random) never returned negative values. * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the subseconds part to the entropy, as that's a bit more random. Prefer signed to unsigned, since the signedness doesn't matter and in general we prefer signed.

This is more efficient than Ffile_directory_p and avoids a minor race. 2011-07-04 Lars Magne Ingebrigtsen * buffer.c (Foverlay_put): Say what the return value is (bug#7835). * fileio.c (barf_or_query_if_file_exists): Check first if the file is a directory before asking whether to use the file name (bug#7564). (barf_or_query_if_file_exists): Make the "File is a directory" error be more correct. * fns.c (Frequire): Remove the mention of the .gz files, since that's installation-specific, but keep the mention of `get-load-suffixes'. 2011-07-04 Paul Eggert * editfns.c (Fformat_time_string): Don't assume strlen fits in int. Report string overflow if the output is too long. 2011-07-04 Juanma Barranquero * gnutls.c (Fgnutls_boot): Don't mention :verify-error. (syms_of_gnutls): Remove duplicate DEFSYM for Qgnutls_bootprop_verify_hostname_error, an error for Qgnutls_bootprop_verify_error (which is no longer used). * eval.c (find_handler_clause): Remove parameters `sig' and `data', unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.

Do not assume that "int nargs : BITS_PER_INT - 2;" produces a signed bit field, as this assumption is not portable and it makes Emacs crash when compiled with Sun C 5.8 on sparc. Do not use "char debug_on_exit : 1" as this is not portable either; instead, use the portable "unsigned int debug_on_exit : 1". Remove unused member evalargs.

The following patches are for when GLYPH_DEBUG && !XASSERT. * dispextern.h (trace_redisplay_p, dump_glyph_string): * dispnew.c (flush_stdout): * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph): Mark as externally visible. * dispnew.c (check_window_matrix_pointers): Now static. * dispnew.c (window_to_frame_vpos): * xfns.c (unwind_create_frame): * xterm.c (x_check_font): Remove unused local. * scroll.c (CHECK_BOUNDS): * xfaces.c (cache_fache): Rename local to avoid shadowing. * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static. * xdisp.c (check_window_end): Now a no-op if !XASSERTS. (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos) (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos): Now static. (debug_method_add): Use va_list and vsprintf rather than relying on undefined behavior with wrong number of arguments. (dump_glyph, dump_glyph_row, Fdump_glyph_matrix): Don't assume ptrdiff_t and EMACS_INT are the same width as int. In this code, it's OK to assume C99 behavior for ptrdiff_t formats since we're not interested in debugging glyphs with old libraries. * xfaces.c (cache_face): Move debugging code earlier; this pacifies GCC 4.6.0's static checking. 2011-06-22 Paul Eggert Integer overflow and signedness fixes (Bug#8873). A few related buffer overrun fixes, too. * font.c (font_score): Use EMACS_INT, not int, to store XINT value. * dispextern.h (struct face.stipple): * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap) (x_bitmap_mask, x_allocate_bitmap_record) (x_create_bitmap_from_data, x_create_bitmap_from_file) (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask) (x_create_bitmap_from_xpm_data): * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last): * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size) (.bitmaps_last): * xfaces.c (load_pixmap): * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap): * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size) (.bitmaps_last, struct x_output.icon_bitmap): Use ptrdiff_t, not int, for bitmap indexes. (x_allocate_bitmap_record): Check for size overflow. * dispextern.h, lisp.h: Adjust to API changes elsewhere. Use ptrdiff_t, not int, for overlay counts. * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT): * editfns.c (overlays_around, get_pos_property): * textprop.c (get_char_property_and_overlay): * xdisp.c (next_overlay_change, note_mouse_highlight): * xfaces.c (face_at_buffer_position): * buffer.c (OVERLAY_COUNT_MAX): New macro. (overlays_at, overlays_in, sort_overlays, Foverlays_at) (Fnext_overlay_change, Fprevious_overlay_change) (mouse_face_overlay_overlaps, Foverlays_in): Use ptrdiff_t, not int, for sizes. (overlays_at, overlays_in): Check for size-calculation overflow. * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int. * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen. (x_session_initialize): Do not assume string length fits in int. * xsettings.c (apply_xft_settings): Fix potential buffer overrun. This is unlikely, but can occur if DPI is outlandish. * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font): * xselect.c (Fx_get_atom_name): Avoid need for strlen. * xrdb.c: Don't assume strlen fits in int; avoid some strlens. * xrdb.c (magic_file_p, search_magic_path): Omit last arg SUFFIX; it was always 0. All callers changed. (magic_file_p): Use ptrdiff_t, not int. Check for size overflow. * xfont.c (xfont_match): Avoid need for strlen. * xfns.c: Don't assume strlen fits in int. (xic_create_fontsetname, x_window): Use ptrdiff_t, not int. * xdisp.c (message_log_check_duplicate): Return intmax_t, not unsigned long, as we prefer signed integers. All callers changed. Detect integer overflow in repeat count. (message_dolog): Don't assume print length fits in 39 bytes. (display_mode_element): Don't assume strlen fits in int. * termcap.c: Don't assume sizes fit in int and never overflow. (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes. (gobble_line): Check for size-calculation overflow. * minibuf.c (Fread_buffer): * lread.c (intern, intern_c_string): * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]: Don't assume string length fits in int. * keyboard.c (parse_tool_bar_item): * gtkutil.c (style_changed_cb): Avoid need for strlen. * font.c: Don't assume string length fits in int. (font_parse_xlfd, font_parse_fcname, font_unparse_fcname): Use ptrdiff_t, not int. (font_intern_prop): Don't assume string length fits in int. Don't assume integer property fits in fixnum. * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int. * filelock.c: Fix some buffer overrun and integer overflow issues. (get_boot_time): Don't assume gzip command string fits in 100 bytes. Reformulate so as not to need the command string. Invoke gzip -cd rather than gunzip, as it's more portable. (lock_info_type, lock_file_1, lock_file): Don't assume pid_t and time_t fit in unsigned long. (LOCK_PID_MAX): Remove; we now use more-reliable bounds. (current_lock_owner): Prefer signed type for sizes. Use memcpy, not strncpy, where memcpy is what is really wanted. Don't assume (via atoi) that time_t and pid_t fit in int. Check for time_t and/or pid_t out of range, e.g., via a network share. Don't alloca where an auto var works fine. * fileio.c: Fix some integer overflow issues. (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name): Don't assume string length fits in int. (directory_file_name): Don't assume string length fits in long. (make_temp_name): Don't assume pid fits in int, or that its print length is less than 20. * data.c (Fsubr_name): Rewrite to avoid a strlen call. * coding.c (make_subsidiaries): Don't assume string length fits in int. * callproc.c (child_setup): Rewrite to avoid two strlen calls. * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT. We prefer signed integers, even for size calculations. * emacs.c: Don't assume string length fits in 'int'. (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int. (main): Don't invoke strlen when not needed. * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string. (XD_DEBUG_MESSAGE): Don't waste a byte. * callproc.c (getenv_internal_1, getenv_internal) (Fgetenv_internal): * buffer.c (init_buffer): Don't assume string length fits in 'int'. * lread.c (invalid_syntax): Omit length argument. All uses changed. This doesn't fix a bug, but it simplifies the code away from its former Hollerith-constant appearance, and it's one less 'int' to worry about when looking at integer-overflow issues. (string_to_number): Simplify 2011-04-26 change by invoking xsignal1. * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr). This didn't break anything, but it didn't help either. It's confusing to put a bogus integer in a place where the actual value does not matter. (LIST_END_P): Remove unused macro and its bogus comment. (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT. * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT. This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE, implementation. (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT. We prefer signed types, and the value cannot exceed the EMACS_INT range anyway (because otherwise the length would not be representable). (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t, not EMACS_UINT and EMACS_INT, when converting pointer to integer. This avoids a GCC warning when WIDE_EMACS_INT. * indent.c (sane_tab_width): New function. (current_column, scan_for_column, Findent_to, position_indentation) (compute_motion): Use it. This is just for clarity. (Fcompute_motion): Don't assume hscroll and tab offset fit in int. * image.c (xbm_image_p): Don't assume stated width, height fit in int. * lisp.h (lint_assume): New macro. * composite.c (composition_gstring_put_cache): * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0. * editfns.c, insdel.c: Omit unnecessary forward decls, to simplify future changes. * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths. * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'. * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'. Use much-faster test for byte-length change. Don't assume string byte-length fits in 'int'. Check that character arg fits in 'int'. (mapcar1): Declare byte as byte, for clarity. * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication. * fns.c (concat): Catch string overflow earlier. Do not rely on integer wraparound. * dispextern.h (struct it.overlay_strings_charpos) (struct it.selective): Now EMACS_INT, not int. * xdisp.c (forward_to_next_line_start) (back_to_previous_visible_line_start) (reseat_at_next_visible_line_start, next_element_from_buffer): Don't arbitrarily truncate the value of 'selective' to int. * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0. * composite.c: Don't truncate sizes to 'int'. (composition_gstring_p, composition_reseat_it) (composition_adjust_point): Use EMACS_INT, not int. (get_composition_id, composition_gstring_put_cache): Use EMACS_INT, not EMACS_UINT, for indexes. * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT. * buffer.c: Include . (struct sortvec.priority, struct sortstr.priority): Now EMACS_INT, not int. (compare_overlays, cmp_for_strings): Avoid subtraction overflow. (struct sortstr.size, record_overlay_string) (struct sortstrlist.size, struct sortlist.used): Don't truncate size to int. (record_overlay_string): Check for size-calculation overflow. (init_buffer_once): Check at compile-time, not run-time. 2011-06-22 Jim Meyering Don't leak an XBM-image-sized buffer * image.c (xbm_load): Free the image buffer after using it. 2011-06-21 Paul Eggert Port to Sun C. * composite.c (find_automatic_composition): Omit needless 'return 0;' that Sun C diagnosed. * fns.c (secure_hash): Fix pointer signedness issue. * intervals.c (static_offset_intervals): New function. (offset_intervals): Use it. 2011-06-21 Leo Liu * deps.mk (fns.o): * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and sha512.h. * fns.c (secure_hash): Rename from crypto_hash_function and change the first arg to accept symbols. (Fsecure_hash): New primitive. (syms_of_fns): New symbols. 2011-06-20 Deniz Dogan * process.c (Fset_process_buffer): Clarify return value in docstring. 2011-06-18 Chong Yidong * dispnew.c (add_window_display_history): Use BVAR. * xdisp.c (debug_method_add): Use BVAR. (check_window_end, dump_glyph_matrix, dump_glyph) (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C. * xfaces.c (check_lface_attrs, check_lface, dump_realized_face): Likewise. * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache check till after the cache is created in init_frame_faces. 2011-06-17 Stefan Monnier * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup. 2011-06-16 Paul Eggert * lisp.h: Include , for INT_MAX, LONG_MAX, LLONG_MAX. Without this, prin1 mishandles Lisp_Misc_Save_Value printing on hosts with pre-C99 libraries, because pD is wrongly defined to "t". Improve buffer-overflow checking (Bug#8873). * fileio.c (Finsert_file_contents): * insdel.c (insert_from_buffer_1, replace_range, replace_range_2): Remove the old (too-loose) buffer overflow checks. They weren't needed, since make_gap checks for buffer overflow. * insdel.c (make_gap_larger): Catch buffer overflows that were missed. The old code merely checked for Emacs fixnum overflow, and relied on undefined (wraparound) behavior. The new code avoids undefined behavior, and also checks for ptrdiff_t and/or size_t overflow. * editfns.c (Finsert_char): Don't dump core with very negative counts. Tune. Don't use wider integers than needed. Don't use alloca. Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test. * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing. * insdel.c, lisp.h (buffer_overflow): New function. (insert_from_buffer_1, replace_range, replace_range_2): * insdel.c (make_gap_larger): * editfns.c (Finsert_char): * fileio.c (Finsert_file_contents): Use it, to normalize wording. * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed. 2011-06-15 Paul Eggert Integer overflow and signedness fixes (Bug#8873, Bug#8828). * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772. (GET_CCL_RANGE, IN_INT_RANGE): Use it. * fileio.c: Don't assume EMACS_INT fits in off_t. (emacs_lseek): New static function. (Finsert_file_contents, Fwrite_region): Use it. Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate. * fns.c (Fload_average): Don't assume 100 * load average fits in int. * fns.c: Don't overflow int when computing a list length. * fns.c (QUIT_COUNT_HEURISTIC): New constant. (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted truncation on 64-bit hosts. Check for QUIT every QUIT_COUNT_HEURISTIC entries rather than every other entry; that's faster and is responsive enough. (Flength): Report an error instead of overflowing an integer. (Fsafe_length): Return a float if the value is not representable as a fixnum. This shouldn't happen except in contrived situations. (Fnthcdr, Fsort): Don't assume list length fits in int. (Fcopy_sequence): Don't assume vector length fits in int. * alloc.c: Check that resized vectors' lengths fit in fixnums. (header_size, word_size): New constants. (allocate_vectorlike): Don't check size overflow here. (allocate_vector): Check it here instead, since this is the only caller of allocate_vectorlike that could cause overflow. Check that the new vector's length is representable as a fixnum. * fns.c (next_almost_prime): Don't return a multiple of 3 or 5. The previous code was bogus. For example, next_almost_prime (32) returned 39, which is undesirable as it is a multiple of 3; and next_almost_prime (24) returned 25, which is a multiple of 5 so why was the code bothering to check for multiples of 7? * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length. * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now. Variadic C functions now count arguments with ptrdiff_t. This partly undoes my 2011-03-30 change, which replaced int with size_t. Back then I didn't know that the Emacs coding style prefers signed int. Also, in the meantime I found a few more instances where arguments were being counted with int, which may truncate counts on 64-bit machines, or EMACS_INT, which may be unnecessarily wide. * lisp.h (struct Lisp_Subr.function.aMANY) (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Arg counts are now ptrdiff_t, not size_t. All variadic functions and their callers changed accordingly. (struct gcpro.nvars): Now size_t, not size_t. All uses changed. * bytecode.c (exec_byte_code): Check maxdepth for overflow, to avoid potential buffer overrun. Don't assume arg counts fit in 'int'. * callint.c (Fcall_interactively): Check arg count for overflow, to avoid potential buffer overrun. Use signed char, not 'int', for 'varies' array, so that we needn't bother to check its size calculation for overflow. * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args. * eval.c (apply_lambda): * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length. (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed. (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args. * callint.c (Fcall_interactively): Don't use index var as event count. * vm-limit.c (check_memory_limits): Fix incorrect extern function decls. * mem-limits.h (SIZE): Remove; no longer used. * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works. Remove unnecessary casts. * xterm.c (x_term_init): * xfns.c (x_set_border_pixel): * widget.c (create_frame_gcs): Remove casts to unsigned long etc. These aren't needed now that we assume ANSI C. * sound.c (Fplay_sound_internal): Remove cast to unsigned long. It's more likely to cause problems (due to unsigned overflow) than to cure them. * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts. * unexelf.c (unexec): Don't assume BSS addr fits in unsigned. * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned. * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX. * lisp.h (CHAR_TABLE_SET): Omit now-redundant test. * lread.c (Fload): Don't compare a possibly-garbage time_t value. GLYPH_CODE_FACE returns EMACS_INT, not int. * dispextern.h (merge_faces): * xfaces.c (merge_faces): * xdisp.c (get_next_display_element, next_element_from_display_vector): Don't assume EMACS_INT fits in int. * character.h (CHAR_VALID_P): Remove unused parameter. * fontset.c, lisp.h, xdisp.c: All uses changed. * editfns.c (Ftranslate_region_internal): Omit redundant test. * fns.c (concat): Minor tuning based on overflow analysis. This doesn't fix any bugs. Use int to hold character, instead of constantly refetching from Emacs object. Use XFASTINT, not XINT, for value known to be a character. Don't bother comparing a single byte to 0400, as it's always less. * floatfns.c (Fexpt): * fileio.c (make_temp_name): Omit unnecessary cast to unsigned. * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT for characters. * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives. * data.c (Faset): If ARRAY is a string, check that NEWELT is a char. Without this fix, on a 64-bit host (aset S 0 4294967386) would incorrectly succeed when S was a string, because 4294967386 was truncated before it was used. * chartab.c (Fchar_table_range): Use CHARACTERP to check range. Otherwise, an out-of-range integer could cause undefined behavior on a 64-bit host. * composite.c: Use int, not EMACS_INT, for characters. (fill_gstring_body, composition_compute_stop_pos): Use int, not EMACS_INT, for values that are known to be in character range. This doesn't fix any bugs but is the usual style inside Emacs and may generate better code on 32-bit machines. Make sure a 64-bit char is never passed to ENCODE_CHAR. This is for reasons similar to the recent CHAR_STRING fix. * charset.c (Fencode_char): Check that character arg is actually a character. Pass an int to ENCODE_CHAR. * charset.h (ENCODE_CHAR): Verify that the character argument is no wider than 'int', as a compile-time check to prevent future regressions in this area. * character.c (char_string): Remove unnecessary casts. Make sure a 64-bit char is never passed to CHAR_STRING. Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform, by silently ignoring the top 32 bits, allowing some values that were far too large to be valid characters. * character.h: Include . (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character arguments are no wider than unsigned, as a compile-time check to prevent future regressions in this area. * data.c (Faset): * editfns.c (Fchar_to_string, general_insert_function, Finsert_char) (Fsubst_char_in_region): * fns.c (concat): * xdisp.c (decode_mode_spec_coding): Adjust to CHAR_STRING's new requirement. * editfns.c (Finsert_char, Fsubst_char_in_region): * fns.c (concat): Check that character args are actually characters. Without this test, these functions did the wrong thing with wildly out-of-range values on 64-bit hosts. Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts. These casts should not be needed on 32-bit hosts, either. * keyboard.c (read_char): * lread.c (Fload): Remove casts to unsigned. * lisp.h (UNSIGNED_CMP): New macro. This fixes comparison bugs on 64-bit hosts. (ASCII_CHAR_P): Use it. * casefiddle.c (casify_object): * character.h (ASCII_BYTE_P, CHAR_VALID_P) (SINGLE_BYTE_CHAR_P, CHAR_STRING): * composite.h (COMPOSITION_ENCODE_RULE_VALID): * dispextern.h (FACE_FROM_ID): * keyboard.c (read_char): Use UNSIGNED_CMP. * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t, not to EMACS_INT, to avoid GCC warning. * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals. * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast. The cast incorrectly truncated 64-bit byte offsets to 32 bits, and isn't needed on 32-bit machines. * buffer.c (Fgenerate_new_buffer_name): Use EMACS_INT for count, not int. (advance_to_char_boundary): Return EMACS_INT, not int. * data.c (Qcompiled_function): Now static. * window.c (window_body_lines): Now static. * image.c (gif_load): Rename local to avoid shadowing. * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow. (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member. * alloc.c (make_save_value): Integer argument is now of type ptrdiff_t, not int. (mark_object): Use ptrdiff_t, not int. * lisp.h (pD): New macro. * print.c (print_object): Use it. * alloc.c: Use EMACS_INT, not int, to count objects. (total_conses, total_markers, total_symbols, total_vector_size) (total_free_conses, total_free_markers, total_free_symbols) (total_free_floats, total_floats, total_free_intervals) (total_intervals, total_strings, total_free_strings): Now EMACS_INT, not int. All uses changed. (Fgarbage_collect): Compute overall total using a double, so that integer overflow is less likely to be a problem. Check for overflow when converting back to an integer. (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks) (n_vectors, n_symbol_blocks, n_marker_blocks): Remove. These were 'int' variables that could overflow on 64-bit hosts; they were never used, so remove them instead of repairing them. (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'. (inhibit_garbage_collection): Set gc_cons_threshold to max value. Previously, this ceilinged at INT_MAX, but that doesn't work on 64-bit machines. (allocate_pseudovector): Don't use EMACS_INT when int would do. * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int. (allocate_vectorlike): Check for ptrdiff_t overflow. (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT when a (possibly-narrower) signed value would do just as well. We prefer using signed arithmetic, to avoid comparison confusion. * alloc.c: Catch some string size overflows that we were missing. (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0, for convenience in STRING_BYTES_MAX. (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h. The definition here is exact; the one in lisp.h was approximate. (allocate_string_data): Check for string overflow. This catches some instances we weren't catching before. Also, it catches size_t overflow on (unusual) hosts where SIZE_MAX <= min (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits and ptrdiff_t and EMACS_INT are both 64 bits. * character.c, coding.c, doprnt.c, editfns.c, eval.c: All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND. * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX. * character.c (string_escape_byte8): Fix nbytes/nchars typo. * alloc.c (Fmake_string): Check for out-of-range init. 2011-06-15 Stefan Monnier * eval.c (Fdefvaralias): Also mark the target as variable-special-p. 2011-06-14 Jan Djärv * xfns.c (x_set_scroll_bar_default_width): Remove argument to xg_get_default_scrollbar_width. * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3. (int_gtk_range_get_value): Move to the scroll bar part of the file. (style_changed_cb): Call update_theme_scrollbar_width and call x_set_scroll_bar_default_width and xg_frame_set_char_size for all frames (Bug#8505). (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505). Call gtk_window_set_resizable if HAVE_GTK3. (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width and height if HAVE_GTK3 (Bug#8505). (scroll_bar_width_for_theme): New variable. (update_theme_scrollbar_width): New function. (xg_get_default_scrollbar_width): Move code to update_theme_scrollbar_width, just return scroll_bar_width_for_theme. (xg_initialize): Call update_theme_scrollbar_width. * gtkutil.h (xg_get_default_scrollbar_width): Remove argument. * emacsgtkfixed.c, emacsgtkfixed.h: New files. 2011-06-12 Martin Rudalics * frame.c (make_frame): Call other_buffer_safely instead of other_buffer. * window.c (temp_output_buffer_show): Call display_buffer with second argument Vtemp_buffer_show_specifiers and reset latter immediately after the call. (Vtemp_buffer_show_specifiers): New variable. (auto_window_vscroll_p, next_screen_context_lines) (Vscroll_preserve_screen_position): Remove leading asterisks from doc-strings. 2011-06-12 Paul Eggert Fix minor problems found by GCC 4.6.0 static checking. * buffer.c (Qclone_number): Remove for now, as it's unused.

(consing_since_gc): Now EMACS_INT, since a single hash table can use more than INT_MAX bytes. 2011-06-01 Dan Nicolaescu Make it possible to build with GCC-4.6+ -O2 -flto. * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE. 2011-06-01 Stefan Monnier * minibuf.c (get_minibuffer, read_minibuf_unwind): Call minibuffer-inactive-mode. 2011-05-31 Juanma Barranquero * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)): Update dependencies. 2011-05-31 Dan Nicolaescu * data.c (init_data): Remove code for UTS, this system is not supported anymore. 2011-05-31 Dan Nicolaescu Don't force ./temacs to start in terminal mode. * frame.c (make_initial_frame): Initialize faces in all cases, not only when CANNOT_DUMP is defined. * dispnew.c (init_display): Remove CANNOT_DUMP condition. 2011-05-31 Dan Nicolaescu * dispnew.c (add_window_display_history): Use const for the string pointer. Remove declaration, not needed. 2011-05-31 Paul Eggert Use 'inline', not 'INLINE'. * alloc.c, fontset.c (INLINE): Remove. * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c: * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c: * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline. * gmalloc.c (register_heapinfo): Use inline unconditionally. * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__. 2011-05-31 Dan Nicolaescu Make it possible to run ./temacs. * callproc.c (set_initial_environment): Remove CANNOT_DUMP code, syms_of_callproc does the same thing. Remove test for "initialized", do it in the caller. * emacs.c (main): Avoid calling set_initial_environment when dumping. 2011-05-31 Stefan Monnier * minibuf.c (Finternal_complete_buffer): Return `category' metadata. (read_minibuf): Use get_minibuffer. (syms_of_minibuf): Use DEFSYM. (Qmetadata): New var. * data.c (Qbuffer): Don't make it static. (syms_of_data): Use DEFSYM. 2011-05-31 Paul Eggert * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751) (CCL_CODE_MIN): New macro. 2011-05-30 Paul Eggert * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests. * eval.c (Qdebug): Now static. * lisp.h (Qdebug): Remove decl. This reverts a part of the 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of 2011-04-14T06:48:41Z!eggert@cs.ucla.edu. 2011-05-29 Chong Yidong * image.c: Various fixes to ImageMagick code comments. (Fimagemagick_types): Doc fix. 2011-05-29 Paul Eggert Minor fixes prompted by GCC 4.6.0 warnings. * xselect.c (converted_selections, conversion_fail_tag): Now static. * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h". (x_clipboard_manager_save_all): Move extern decl to ... * xterm.h: ... here, so that it can be checked for consistency. 2011-05-29 Chong Yidong * xselect.c (x_clipboard_manager_save_frame) (x_clipboard_manager_save_all): New functions. (Fx_clipboard_manager_save): Lisp function deleted. * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all. * frame.c (delete_frame): Call x_clipboard_manager_save_frame. * xterm.h: Update prototype. 2011-05-28 William Xu * nsterm.m (ns_term_shutdown): Synchronize user defaults before exiting (Bug#8239). 2011-05-28 Jim Meyering Avoid a sign-extension bug in crypto_hash_function. * fns.c (to_uchar): Define. (crypto_hash_function): Use it to convert some newly-signed variables to unsigned, to avoid sign-extension bugs. For example, without this change, (md5 "truc") would evaluate to 45723a2aff78ff4fff7fff1114760e62 rather than the expected 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in https://lists.gnu.org/r/emacs-devel/2011-05/msg00883.html. 2011-05-27 Paul Eggert Integer overflow fixes. * dbusbind.c: Serial number integer overflow fixes. (CHECK_DBUS_SERIAL_GET_SERIAL): New macro. (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float to hold a serial number that is too large for a fixnum. (Fdbus_method_return_internal, Fdbus_method_error_internal): Check for serial numbers out of range. Decode any serial number that was so large that it became a float. (Bug#8722) * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg. (Fdbus_call_method, Fdbus_call_method_asynchronously): Use XFASTINT rather than XUINT when numbers are nonnegative. (xd_append_arg, Fdbus_method_return_internal): (Fdbus_method_error_internal): Likewise. Also, for unsigned arguments, check that Lisp number is nonnegative, rather than silently wrapping negative numbers around. (Bug#8722) (xd_read_message_1): Don't assume dbus_uint32_t can fit in int. (Bug#8722) * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT. * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'. ccl: Add integer overflow checks. * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT): (IN_INT_RANGE): New macros. (ccl_driver): Use them to check for integer overflow when decoding a CCL program. Many of the new checks are whether XINT (x) fits in int; it doesn't always, on 64-bit hosts. The new version doesn't catch all possible integer overflows, but it's an improvement. (Bug#8719) * alloc.c (make_event_array): Use XINT, not XUINT. There's no need for unsigned here. * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t This follows up to the 2011-05-06 change that substituted uintptr_t for EMACS_INT. This case wasn't caught back then. Rework Fformat to avoid integer overflow issues. * editfns.c: Include unconditionally, as it's everywhere now (part of C89). Include . (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed. (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns. (Fformat): Avoid the prepass trying to compute sizes; it was only approximate and thus did not catch overflow reliably. Instead, walk through the format just once, formatting and computing sizes as we go, checking for integer overflow at every step, and allocating a larger buffer as needed. Keep track separately whether the format is multibyte. Keep only the most-recently calculated precision, rather than them all. Record whether each argument has been converted to string. Use EMACS_INT, not int, for byte and char and arg counts. Support field widths and precisions larger than INT_MAX. Avoid sprintf's undefined behavior with conversion specifications such as %#d and %.0c. Fix bug with strchr succeeding on '\0' when looking for flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when formatting out-of-range floating point numbers with int formats. (Bug#8668) * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN. * data.c: Avoid integer truncation in expressions involving floats. * data.c: Include . (arith_driver): When there's an integer overflow in an expression involving floating point, convert the integers to floating point so that the resulting value does not suffer from catastrophic integer truncation. For example, on a 64-bit host (* 4 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero. Do not rely on undefined behavior after integer overflow. merge count_size_as_multibyte, parse_str_to_multibyte * character.c, character.h (count_size_as_multibyte): Rename from parse_str_to_multibyte; all uses changed. Check for integer overflow. * insdel.c, lisp.h (count_size_as_multibyte): Remove, since it's now a duplicate of the other. This is more of a character than a buffer op, so better that it's in character.c. * fns.c, print.c: Adjust to above changes. 2011-05-27 Stefan Monnier * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup. 2011-05-27 Paul Eggert * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings. (x_handle_selection_request, frame_for_x_selection): Remove unused vars. (x_clipboard_manager_save): Now static. (Fx_clipboard_manager_save): Rename local to avoid shadowing. * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings. (crypto_hash_function): Now static. Fix pointer signedness problems. Avoid unnecessary initializations. 2011-05-27 Chong Yidong * termhooks.h (Vselection_alist): Make it terminal-local. * terminal.c (create_terminal): Initialize it. * xselect.c: Support for clipboard managers. (Vselection_alist): Move to termhooks.h as terminal-local var. (LOCAL_SELECTION): New macro. (x_atom_to_symbol): Handle x_display_info_for_display fail case. (symbol_to_x_atom): Remove gratuitous arg. (x_handle_selection_request, lisp_data_to_selection_data) (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed. (x_own_selection, x_get_local_selection, x_convert_selection): New arg, specifying work frame. Use terminal-local Vselection_alist. (some_frame_on_display): Delete unused function. (Fx_own_selection_internal, Fx_get_selection_internal) (Fx_disown_selection_internal, Fx_selection_owner_p) (Fx_selection_exists_p): New optional frame arg. (frame_for_x_selection, Fx_clipboard_manager_save): New functions. (x_handle_selection_clear): Don't treat other terminals with the same keyboard specially. Use the terminal-local Vselection_alist. (x_clear_frame_selections): Use Frun_hook_with_args. * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms. * xterm.h: Add support for those atoms. 2011-05-26 Chong Yidong * xselect.c: ICCCM-compliant handling of MULTIPLE targets. (converted_selections, conversion_fail_tag): New global variables. (x_selection_request_lisp_error): Free the above. (x_get_local_selection): Remove unnecessary code. (x_reply_selection_request): Args changed; handle arbitrary array of converted selections stored in converted_selections. Separate the XChangeProperty and SelectionNotify steps. (x_handle_selection_request): Rewrite to handle MULTIPLE target. (x_convert_selection): New function. (x_handle_selection_event): Simplify. (x_get_foreign_selection): Don't ignore incoming requests while waiting for an answer; this will fail when we implement SAVE_TARGETS, and seems unnecessary anyway. (selection_data_to_lisp_data): Recognize ATOM_PAIR type. (Vx_sent_selection_functions): Doc fix. 2011-05-26 Leo Liu * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699) 2011-05-25 YAMAMOTO Mitsuharu * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p. * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row for fringe update if it has periodic bitmap. (row_equal_p): Also compare left_fringe_offset, right_fringe_offset, and fringe_bitmap_periodic_p. * fringe.c (get_fringe_bitmap_data): New function. (draw_fringe_bitmap_1, update_window_fringes): Use it. (update_window_fringes): Record periodicity of fringe bitmap in glyph row. Mark glyph row for fringe update if periodicity changed. * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row for fringe update unless it has periodic bitmap. 2011-05-25 Kenichi Handa * xdisp.c (get_next_display_element): Set correct it->face_id for a static composition. 2011-05-24 Leo Liu * deps.mk (fns.o): * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h. * fns.c (crypto_hash_function, Fsha1): New function. (Fmd5): Use crypto_hash_function. (syms_of_fns): Add Ssha1. 2011-05-22 Paul Eggert * gnutls.c: Remove unused macros. (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function): (fn_gnutls_transport_set_push_function) [!WINDOWSNT]: Remove macros that are defined and never used. Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14). 2011-05-22 Chong Yidong * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS. (Fx_get_selection_internal): Minor cleanup. (Fx_own_selection_internal): Rename arguments for consistency with select.el. 2011-05-22 Paul Eggert * xselect.c (QSAVE_TARGETS): New static var, to fix build failure. 2011-05-22 Chong Yidong * xselect.c (syms_of_xselect): Include character.h; use DEFSYM. 2011-05-21 YAMAMOTO Mitsuharu * dispnew.c (scrolling_window): Don't exclude the case that the last enabled row in the desired matrix touches the bottom boundary. 2011-05-21 Glenn Morris * Makefile.in ($(etc)/DOC): Make second command line even shorter. (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion, and add some more files. 2011-05-20 Eli Zaretskii * callproc.c (Fcall_process) [MSDOS]: Fix arguments to report_file_error introduced by the change from 2011-05-07. 2011-05-20 Paul Eggert * systime.h (Time): Define only if emacs is defined. This is to allow ../lib-src/profile.c to be compiled on FreeBSD, where the include path doesn't have X11/X.h by default. See . 2011-05-20 Kenichi Handa * composite.c (find_automatic_composition): Fix previous change. 2011-05-20 Glenn Morris * lisp.mk: New file, split from Makefile.in. * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@. (shortlisp): Remove. ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp. 2011-05-19 Glenn Morris * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT) (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT) (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove. (lisp): Set the order to that of loadup.el. (shortlisp): Make it a copy of $lisp. (SOME_MACHINE_LISP): Remove. ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too. Use just $shortlisp, not $SOME_MACHINE_LISP too. 2011-05-18 Kenichi Handa * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency. (BACKWARD_CHAR): Wrap the arg STOP by parenthesis. (find_automatic_composition): Mostly rewrite for efficiency. 2011-05-18 Juanma Barranquero * makefile.w32-in: Update dependencies. 2011-05-18 Christoph Scholtes * menu.c: Include limits.h (fixes the MS-Windows build broken by 2011-06-18T18:49:19Z!cyd@stupidchicken.com). 2011-05-18 Paul Eggert Fix some integer overflow issues, such as string length overflow. * insdel.c (count_size_as_multibyte): Check for string overflow. * character.c (lisp_string_width): Check for string overflow. Use EMACS_INT, not int, for string indexes and lengths; in particular, 2nd arg is now EMACS_INT, not int. Do not crash if the resulting string length overflows an EMACS_INT; instead, report a string overflow if no precision given. When checking for precision exhaustion, use a check that cannot possibly have integer overflow. (Bug#8675) * character.h (lisp_string_width): Adjust to new signature. * alloc.c (string_overflow): New function. (Fmake_string): Use it. This doesn't change behavior, but saves a few bytes and will simplify future changes. * character.c (string_escape_byte8): Likewise. * lisp.h (string_overflow): New decl. Fixups, following up to the user-interface timestamp change. * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time for UI timestamps, instead of unsigned long. * msdos.c (mouse_get_pos): Likewise. * w32inevt.c (movement_time, w32_console_mouse_position): Likewise. * w32gui.h (Time): Define by including "systime.h" rather than by declaring it ourselves. (Bug#8664) * dispextern.h (struct image): Don't assume time_t <= unsigned long. * image.c (clear_image_cache): Likewise. * term.c (term_mouse_position): Don't assume time_t wraparound. Be more systematic about user-interface timestamps. Before, the code sometimes used 'Time', sometimes 'unsigned long', and sometimes 'EMACS_UINT', to represent these timestamps. This change causes it to use 'Time' uniformly, as that's what X uses. This makes the code easier to follow, and makes it easier to catch integer overflow bugs such as Bug#8664. * frame.c (Fmouse_position, Fmouse_pixel_position): Use Time, not unsigned long, for user-interface timestamps. * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise. (button_down_time, make_lispy_position, make_lispy_movement): Likewise. * keyboard.h (last_event_timestamp): Likewise. * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise. * menu.h (xmenu_show): Likewise. * term.c (term_mouse_position): Likewise. * termhooks.h (struct input_event.timestamp): Likewise. (struct terminal.mouse_position_hook): Likewise. * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise. * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise. * systime.h (Time): New decl. Pull it in from if HAVE_X_WINDOWS, otherwise define it as unsigned long, which is what it was before. * menu.h, termhooks.h: Include "systime.h", for Time. * keyboard.c (make_lispy_event): Fix problem in integer overflow. Don't assume that the difference between two unsigned long values can fit into an integer. At this point, we know button_down_time <= event->timestamp, so the difference must be nonnegative, so there's no need to cast the result if double-click-time is nonnegative, as it should be; check that it's nonnegative, just in case. This bug is triggered when events are more than 2**31 ms apart (about 25 days). (Bug#8664) * xselect.c (last_event_timestamp): Remove duplicate decl. (x_own_selection): Remove needless cast to unsigned long. * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes that always fit in int. Use a sentinel instead of a counter, to avoid a temp and to allay GCC's concerns about possible int overflow. * frame.h (struct frame): Use int for menu_bar_items_used instead of EMACS_INT, since it always fits in int. * menu.c (grow_menu_items): Check for int overflow. * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils. * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers. Before, the code was not consistent. These values cannot exceed 2**31 - 1 so there's no need to make them unsigned. (x_x_to_emacs_modifiers): Accept int and return EMACS_INT. (x_emacs_to_x_modifiers): Accept EMACS_INT and return int. (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers as modifiers. * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change. * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT. (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT. Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)), presumably because the widths might not match. * window.c (size_window): Avoid needless test at loop start. 2011-05-18 Courtney Bane (tiny change) * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687). 2011-05-12 Drew Adams * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655). 2011-05-12 YAMAMOTO Mitsuharu * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and `width' to `bar_area_x' and `bar_area_width', respectively. (x_scroll_run): Take account of fringe background extension. * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]: Rename local vars `left' and `width' to `bar_area_x' and `bar_area_width', respectively. (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe background extension. 2011-05-10 Jim Meyering * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the". 2011-05-10 Juanma Barranquero * image.c (Finit_image_library): Return t for built-in image types, like pbm and xbm. (Bug#8640) 2011-05-09 Andreas Schwab * w32menu.c (set_frame_menubar): Fix submenu allocation. 2011-05-07 Eli Zaretskii * w32console.c (Fset_screen_color): Doc fix. (Fget_screen_color): New function. (syms_of_ntterm): Defsubr it. * callproc.c (call_process_cleanup) [MSDOS]: Don't close and unlink the temporary file if Fcall_process didn't create it in the first place. (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the child process will be redirected to a file specified with `:file'. Don't try to re-open tempfile in that case, and set fd[0] to -1 as cue to call_process_cleanup not to close that handle. 2011-05-07 Ben Key * makefile.w32-in: The bootstrap-temacs rule now makes use of one of two shell specific rules, either bootstrap-temacs-CMD or bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical to the previous implementation of the bootstrap-temacs rule. The bootstrap-temacs-CMD rule is similar to the previous implementation of the bootstrap-temacs rule except that it makes use of the ESC_CFLAGS variable instead of the CFLAGS variable. These changes, along with some changes to nt/configure.bat, nt/gmake.defs, and nt/nmake.defs, are required to extend my earlier fix to add support for --cflags and --ldflags options that include quotes so that it works whether make uses cmd or sh as the shell. 2011-05-06 Michael Albinus * dbusbind.c (QCdbus_type_unix_fd): Declare static. (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it is a constant. (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or a string. Handle both cases. (Fdbus_call_method_asynchronously, Fdbus_register_signal) (Fdbus_register_method): Use Qinvalid_function. 2011-05-06 Juanma Barranquero * makefile.w32-in: Update dependencies. (LISP_H): Add inttypes.h and stdin.h. (PROCESS_H): Add unistd.h. 2011-05-06 Eli Zaretskii * lread.c: Include limits.h (fixes the MS-Windows build broken by 2011-05-06T07:13:19Z!eggert@cs.ucla.edu). 2011-05-06 Paul Eggert * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local. * term.c (vfatal): Remove stray call to va_end. It's not needed and the C Standard doesn't allow it here anyway. Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux. * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545) * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM bytes. * term.c: Don't include , as does that. * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering. * process.c (Fformat_network_address): Fix typo: args2 -> *args2. * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times). * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601). * charset.h (struct charset.code_space): Now has 15 elements, not 16. * charset.c (Fdefine_charset_internal): Don't initialize charset.code_space[15]. The value was garbage, on hosts with 32-bit int (Bug#8600). * lread.c (read_integer): Be more consistent with string-to-number. Use string_to_number to do the actual conversion; this avoids rounding errors and fixes some other screwups. Without this fix, for example, #x1fffffffffffffff was misread as -2305843009213693952. (digit_to_number): Move earlier, for benefit of read_integer. Return -1 if the digit is out of range for the base, -2 if it is not a digit in any supported base. (Bug#8602) * doprnt.c (doprnt): Support arbitrary pI values, such as "I64". * dispnew.c (scrolling_window): Return 1 if we scrolled, to match comment at start of function. This also removes a GCC warning about overflow in a 32+64-bit port. * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify. * dbusbind.c: Do not use XPNTR on a value that may be an integer. Reported by Stefan Monnier in . (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages): Use SYMBOLP-guarded XSYMBOL, not XPNTR. * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t. (EMACS_UINTPTR): Likewise, with uintptr_t. * lisp.h: Prefer 64-bit EMACS_INT if available. (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit on 32-bit hosts that have 64-bit int, so that they can access large files. However, temporarily disable this change unless the temporary symbol WIDE_EMACS_INT is defined. * lread.c, process.c: Do not include ; lisp.h does it now. Prefer intptr_t/uintptr_t for integers the same widths as pointers. This removes an assumption that EMACS_INT and long are the same width as pointers. The assumption is true for Emacs porting targets now, but we want to make other targets possible. * lisp.h: Include , for INTPTR_MAX, UINTPTR_MAX. (EMACS_INTPTR, EMACS_UINTPTR): New macros. In the rest of the code, change types of integers that hold casts of pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically replacing EMACS_INT, long, EMACS_UINT, and unsigned long. (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed. (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here. No need to cast type when ORing. (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR. * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast. * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to assume EMACS_INT is the same width as char *. * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb): (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item): Remove no-longer-needed casts. (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback): (xg_tool_bar_help_callback, xg_make_tool_item): Use EMACS_INTPTR to hold an integer that will be cast to void *; this can avoid a GCC warning if EMACS_INT is not the same width as void *. * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast. * xdisp.c (display_echo_area_1, resize_mini_window_1): (current_message_1, set_message_1): Use a local to convert to proper width without a cast. * xmenu.c (dialog_selection_callback): Likewise. * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long. Also, don't assume VALBITS / RAND_BITS is less than 5, and don't rely on undefined behavior when shifting a 1 left into the sign bit. * lisp.h (get_random): Change signature to match. * lread.c (hash_string): Use size_t, not int, for hash computation. Normally we prefer signed values; but hashing is special, because it's better to use unsigned division on hash table sizes so that the remainder is nonnegative. Also, size_t is the natural width for hashing into memory. The previous code used 'int', which doesn't retain enough info to hash well into very large tables. (oblookup, oblookup_last_bucket_number, Funintern): Likewise. * dbusbind.c: Don't possibly lose pointer info when converting. (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages): Use XPNTR rather than XHASH, so that the high-order bits of the pointer aren't lost when converting through void *. * eval.c (Fautoload): Don't double-shift a pointer. * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long. 2011-05-06 Juanma Barranquero * gnutls.c (DEF_GNUTLS_FN): * image.c (DEF_IMGLIB_FN): Make function pointers static. 2011-05-05 Andreas Schwab * lread.c (lisp_file_lexically_bound_p): Stop scanning at end marker.

(emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno): Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno. (emacs_gnutls_write, emacs_gnutls_read) (emacs_gnutls_handle_error, Fgnutls_error_fatalp) (Fgnutls_available_p): New function. (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers. (syms_of_gnutls) : Initialize and staticpro it. (syms_of_gnutls) : defsubr it. * image.c: Include w32.h. (Vimage_type_cache): Delete. (syms_of_image) : Don't initialize and staticpro it.

(wait_reading_process_output): Call emacs_gnutls_record_check_pending instead of gnutls_record_check_pending. * callproc.c, emacs.c: Include lisp.h before w32.h, not after. 2011-05-04 Teodor Zlatanov * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options instead of :keyfiles. Give GnuTLS the keylist and the CRL lists as passed in. 2011-05-03 Jan Djärv * xterm.c (x_set_frame_alpha): Do not set property on anything else than FRAME_X_OUTER_WINDOW (Bug#8608). 2011-05-02 Juanma Barranquero * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596) 2011-05-02 Juanma Barranquero * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon) (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again) (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake) (gnutls_global_initialized, Qgnutls_bootprop_priority) (Qgnutls_bootprop_trustfiles, Qgnutls_bootprop_keyfiles) (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel) (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags) (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error) (Qgnutls_bootprop_callbacks_verify): Make static. 2011-05-01 Andreas Schwab * callproc.c: Indentation fixup. * sysdep.c (wait_for_termination_1): Make static. (wait_for_termination, interruptible_wait_for_termination): Move after wait_for_termination_1. 2011-05-01 Lars Magne Ingebrigtsen * sysdep.c (interruptible_wait_for_termination): New function which is like wait_for_termination, but allows keyboard interruptions. * callproc.c (Fcall_process): Add (:file "file") as an option for the STDOUT buffer. (Fcall_process_region): Ditto. 2011-04-30 Eli Zaretskii * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)' rather than `XVECTOR (FOO)->size'. * process.c: Remove HAVE_INTTYPES_H condition from inclusion of inttypes.h, as a gnulib replacement is used if it not available in system headers. 2011-04-21 Eli Zaretskii Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files. * fileio.c (Finsert_file_contents): Don't limit file size to 1/4 of MOST_POSITIVE_FIXNUM. (Bug#8528) * coding.c (coding_alloc_by_realloc): Error out if destination will grow beyond MOST_POSITIVE_FIXNUM. (decode_coding_emacs_mule): Abort if there isn't enough place in charbuf for the composition carryover bytes. Reserve an extra space for up to 2 characters produced in a loop. (decode_coding_iso_2022): Abort if there isn't enough place in charbuf for the composition carryover bytes. 2011-04-21 Eli Zaretskii * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of aborting when %lld or %lll format is passed. [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when %llo or %llx format is passed. (Bug#8545) * window.c (window_scroll_line_based): Use a marker instead of simple variables to record original value of point. (Bug#7952) * doprnt.c (doprnt): Fix the case where a multibyte sequence produced by %s or %c overflows available buffer space. (Bug#8545) 2011-04-28 Paul Eggert * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545). (SIZE_MAX): Move defn after all includes, as they might #define it. 2011-04-28 Juanma Barranquero * w32.c (init_environment): Warn about defaulting HOME to C:\. 2011-04-28 Juanma Barranquero * keyboard.c (Qdelayed_warnings_hook): Define. (command_loop_1): Run `delayed-warnings-hook' if Vdelayed_warnings_list is non-nil. (syms_of_keyboard) : DEFSYM it. (syms_of_keyboard) : DEFVAR_LISP it. 2011-04-28 Eli Zaretskii * doprnt.c (doprnt): Don't return value smaller than the buffer size if the message was truncated. (Bug#8545). 2011-04-28 Juanma Barranquero * w32fns.c (Fx_change_window_property, Fx_delete_window_property) (Fx_window_property): #if-0 the whole functions, not just the bodies. 2011-04-27 Paul Eggert * doprnt.c (doprnt): Support "ll" length modifier, for long long. 2011-04-27 Juanma Barranquero * makefile.w32-in: Update dependencies. 2011-04-27 Eli Zaretskii Improve `doprnt' and its usage. (Bug#8545) * doprnt.c (doprnt): Make sure `format' is never accessed beyond `format_end'. Remove support for %l as a conversion specifier. Don't use xrealloc. Improve diagnostics when the %l size modifier is used. Update the commentary. * eval.c (verror): Simplify calculation of size_t. * coding.c (Ffind_operation_coding_system): Fix diagnostic error messages. 2011-04-27 Yoshiaki Kasahara (tiny change) * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing change. 2011-04-27 Paul Eggert * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF. This makes this file independent of the recent pseudovector change. 2011-04-26 Paul Eggert * keyboard.c (handle_user_signal): Fix pointer signedness problem. * gnutls.c (emacs_gnutls_handle_error): Remove unused local. (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *. Remove unused local. (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0. * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546) GCC 4.6.0 optimizes based on type-based alias analysis. For example, if b is of type struct buffer * and v of type struct Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size != &v->size, and therefore "v->size = 1; b->size = 2; return v->size;" must therefore return 1. This assumption is incorrect for Emacs, since it type-puns struct Lisp_Vector * with many other types. To fix this problem, this patch adds a new type struct vectorlike_header that documents the constraints on layout of vectors and pseudovectors, and helps optimizing compilers not get fooled by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons. * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of the size member. (XSETPVECTYPE): Rewrite in terms of new macro. (XSETPVECTYPESIZE): New macro, specifying both type and size. This is a bit clearer, and further avoids the possibility of undesirable aliasing. (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size. (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR. (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE, since Lisp_Subr is a special case (no "next" field). (ASIZE): Now uses header.size rather than size. All previous uses of XVECTOR (foo)->size replaced to use this macro, to avoid the hassle of writing XVECTOR (foo)->header.size. (struct vectorlike_header): New type. (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the object, to help avoid aliasing. (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP. (SUBRP): Likewise, since Lisp_Subr is a special case. * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table): (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector): (struct Lisp_Hash_Table): Combine first two members into a single struct vectorlike_header member. All uses of "size" and "next" members changed to be "header.size" and "header.next". * buffer.h (struct buffer): Likewise. * font.h (struct font_spec, struct font_entity, struct font): Likewise. * frame.h (struct frame): Likewise. * process.h (struct Lisp_Process): Likewise. * termhooks.h (struct terminal): Likewise. * window.c (struct save_window_data, struct saved_window): Likewise. * window.h (struct window): Likewise. * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector): Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems. * buffer.c (init_buffer_once): Likewise. * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a special case. * process.c (Fformat_network_address): Use local var for size, for brevity. * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR. Make the Lisp reader and string-to-float more consistent (Bug#8525) * data.c (atof): Remove decl; no longer used or needed. (digit_to_number): Move to lread.c. (Fstring_to_number): Use new string_to_number function, to be consistent with how the Lisp reader treats infinities and NaNs. Do not assume that floating-point numbers represent EMACS_INT without losing information; this is not true on most 64-bit hosts. Avoid double-rounding errors, by insisting on integers when parsing non-base-10 numbers, as the documentation specifies. * lisp.h (string_to_number): New decl, replacing ... (isfloat_string): Remove. * lread.c: Include , for uintmax_t and strtoumax. (read1): Do not accept +. and -. as integers; this appears to have been a coding error. Similarly, do not accept strings like +-1e0 as floating point numbers. Do not report overflow for integer overflows unless the base is not 10 which means we have no simple and reliable way to continue. Break out the floating-point parsing into a new function string_to_number, so that Fstring_to_number parses floating point numbers consistently with the Lisp reader. (digit_to_number): Move here from data.c. Make it static inline. (E_CHAR, EXP_INT): Remove, replacing with ... (E_EXP): New macro, to solve the "1.0e+" problem mentioned below. (string_to_number): New function, replacing isfloat_string. This function checks for valid syntax and produces the resulting Lisp float number too. Rework it so that string-to-number no longer mishandles examples like "1.0e+". Use strtoumax, so that overflow for non-base-10 numbers is reported only when there's no portable and simple way to convert to floating point. * textprop.c (set_text_properties_1): Rewrite for clarity, and to avoid GCC warning about integer overflow. * intervals.h (struct interval): Use EMACS_INT for members where EMACS_UINT might cause problems. See . (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed. * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT. All uses changed. (offset_intervals): Tell GCC not to worry about length overflow when negating a negative length. * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static. (overrun_check_free): Likewise. * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check in the common case where SDATA_DATA_OFFSET is a multiple of Emacs word size. * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10. (gnutls_make_error): Rename local to avoid shadowing. (gnutls_emacs_global_deinit): ifdef out; not used. (Fgnutls_boot): Use const for pointer to readonly storage. Comment out unused local. Fix pointer signedness problems. * lread.c (openp): Don't stuff size_t into an 'int'. Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning about possible signed overflow. * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10. (GDK_KEY_g): Don't define if already defined. (xg_prepare_tooltip): Avoid pointer signedness problem. (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts. * process.c (Fnetwork_interface_info): Avoid left-shift undefined behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts. * xfns.c (Fx_window_property): Simplify a bit, to make a bit faster and to avoid GCC 4.6.0 warning. * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise. * fns.c (internal_equal): Don't assume size_t fits in int. * alloc.c (compact_small_strings): Tighten assertion a little. Replace pEd with more-general pI, and fix some printf arg casts. * lisp.h (pI): New macro, generalizing old pEd macro to other conversion specifiers. For example, use "...%"pI"d..." rather than "...%"pEd"...". (pEd): Remove. All uses replaced with similar uses of pI. * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise. * alloc.c (check_pure_size): Don't overflow by converting size to int. * bidi.c (bidi_dump_cached_states): Use pI to avoid cast. * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort. * dbusbind.c (xd_append_arg): Use pI to avoid cast. (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise. * font.c (font_unparse_xlfd): Avoid potential buffer overrun on 64-bit hosts. (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts. * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts. * print.c (safe_debug_print, print_object): Likewise. (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT to int. Use pI instead of if-then-else-abort. Use %p to avoid casts, avoiding the 0 flag, which is not portable. * process.c (Fmake_network_process): Use pI to avoid cast. * region-cache.c (pp_cache): Likewise. * xdisp.c (decode_mode_spec): Likewise. * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined behavior on 64-bit hosts with printf arg. * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag. (x_stop_queuing_selection_requests): Likewise. (x_get_window_property): Don't truncate byte count to an 'int' when tracing. * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right here, since it parses constructs like leading '-' and spaces, which are not wanted; and it overflows with large numbers. Instead, simply match F[0-9]+, which is what is wanted anyway. * alloc.c: Remove unportable assumptions about struct layout. (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros. (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data): (allocate_vectorlike, make_pure_vector): Use the new macros, plus offsetof, to remove unportable assumptions about struct layout. These assumptions hold on all porting targets that I know of, but they are not guaranteed, they're easy to remove, and removing them makes further changes easier. * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks". This doesn't fix a bug but makes the code clearer. (string_overrun_cookie): Now const. Use initializers that don't formally overflow signed char, to avoid warnings. (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that can cause Emacs to crash when string overrun checking is enabled. (allocate_buffer): Don't assume sizeof (struct buffer) is a multiple of sizeof (EMACS_INT); it need not be, if alignof(EMACS_INT) < sizeof (EMACS_INT). (check_sblock, check_string_bytes, check_string_free_list): Protoize. 2011-04-26 Juanma Barranquero * keyboard.c (QCrtl): Rename from Qrtl. All uses changed. 2011-04-26 Teodor Zlatanov * gnutls.c (emacs_gnutls_handshake): Return an error if we're not supposed to be handshaking. (Bug#8556) Reported by Paul Eggert . 2011-04-26 Daniel Colascione * lisp.h (Qdebug): List symbol. * eval.c (Qdebug): Restore global linkage. * keyboard.c (debug-on-event): New variable. (handle_user_signal): Break into debugger when debug-on-event matches the current signal symbol. 2011-04-25 Dan Nicolaescu * alloc.c (check_sblock, check_string_bytes) (check_string_free_list): Convert to standard C. 2011-04-25 Teodor Zlatanov * w32.c (emacs_gnutls_push): Fix typo. 2011-04-25 Eli Zaretskii * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about "cast to pointer from integer of different size". Improve doprnt and its use in verror. (Bug#8545) * doprnt.c (doprnt): Document the set of format control sequences supported by the function. Use SAFE_ALLOCA instead of always using `alloca'. * eval.c (verror): Don't limit the buffer size at size_max-1, that is one byte too soon. Don't use xrealloc; instead xfree and xmalloc anew. 2011-04-24 Teodor Zlatanov * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the callbacks stage. * gnutls.c: Renamed global_initialized to gnutls_global_initialized. Added internals for the :verify-hostname-error, :verify-error, and :verify-flags parameters of `gnutls-boot' and documented those parameters in the docstring. Start callback support. (emacs_gnutls_handshake): Add Woe32 support. Retry handshake unless a fatal error occurred. Call gnutls_alert_send_appropriate on error. Return error code. (emacs_gnutls_write): Call emacs_gnutls_handle_error. (emacs_gnutls_read): Likewise. (Fgnutls_boot): Return handshake error code. (emacs_gnutls_handle_error): New function. (wsaerror_to_errno): Likewise. * w32.h (emacs_gnutls_pull): Add prototype. (emacs_gnutls_push): Likewise. * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32. (emacs_gnutls_push): Likewise. 2011-04-24 Claudio Bley (tiny change) * process.c (wait_reading_process_output): Check if GnuTLS buffered some data internally if no FDs are set for TLS connections. * makefile.w32-in (OBJ2): Add gnutls.$(O).

(TAGS): Depend on $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h. (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h. * character.c (Fchar_direction): Function deleted. (syms_of_character): Don't defsubr it. : Deleted. 2011-04-23 Eli Zaretskii Fix doprnt so it could be used again safely in `verror'. (Bug#8435) * doprnt.c: Include limits.h. (SIZE_MAX): New macro. (doprnt): Return a size_t value. 2nd arg is now size_t. Many local variables are now size_t instead of int or unsigned. Improve overflow protection. Support `l' modifier for integer conversions. Support %l conversion. Don't assume an EMACS_INT argument for integer conversions and for %c. * lisp.h (doprnt): Restore prototype. * makefile.w32-in ($(BLD)/callint.$(O)): Depend on $(SRC)/character.h. * Makefile.in (base_obj): Add back doprnt.o. * deps.mk (doprnt.o): Add back prerequisites.

(Bug#8496) 2011-04-13 Eli Zaretskii * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init when at ZV. (Bug#8487) 2011-04-12 Andreas Schwab * charset.c (Fclear_charset_maps): Use xfree instead of free. (Bug#8437) * keyboard.c (parse_tool_bar_item): Likewise. * sound.c (sound_cleanup, alsa_close): Likewise. * termcap.c (tgetent): Likewise. * xfns.c (x_default_font_parameter): Likewise. * xsettings.c (read_and_apply_settings): Likewise. * alloc.c (overrun_check_malloc, overrun_check_realloc) (overrun_check_free): Protoize. 2011-04-12 Paul Eggert * sysdep.c (emacs_read, emacs_write): Check for negative sizes since callers should never pass a negative size. Change the signature to match that of plain 'read' and 'write'; see . * lisp.h: Update prototypes of emacs_write and emacs_read. 2011-04-11 Eli Zaretskii * xdisp.c (redisplay_window): Don't try to determine the character position of the scroll margin if the window start point w->startp is outside the buffer's accessible region. (Bug#8468) 2011-04-10 Eli Zaretskii Fix write-region and its subroutines for buffers > 2GB. * fileio.c (a_write, e_write): Modify declaration of arguments and local variables to support buffers larger than 2GB. (Fcopy_file): Use EMACS_INT for return value of emacs_read. * sysdep.c (emacs_write, emacs_read): Use ssize_t for last argument, local variables, and return value. * lisp.h: Update prototypes of emacs_write and emacs_read. * sound.c (vox_write): Use ssize_t for return value of emacs_write. 2011-04-10 Paul Eggert * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack. Fix more problems found by GCC 4.6.0's static checks. * xdisp.c (vmessage): Use a better test for character truncation. * charset.c (load_charset_map): <, not <=, for optimization, and to avoid potential problems with integer overflow. * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise. * casetab.c (set_identity, shuffle): Likewise. * editfns.c (Fformat): Likewise. * syntax.c (skip_chars): Likewise. * xmenu.c (set_frame_menubar): Allocate smaller local vectors. This also lets GCC 4.6.0 generate slightly better loop code. * callint.c (Fcall_interactively): <, not <=, for optimization. (Fcall_interactively): Count the number of arguments produced, not the number of arguments given. This is simpler and lets GCC 4.6.0 generate slightly better code. * ftfont.c: Distinguish more carefully between FcChar8 and char. The previous code passed unsigned char * to a functions like strlen and xstrcasecmp that expect char *, which does not conform to the C standard. (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for arguments to FcPatternGetString, and explicitly cast FcChar8 * to char * when the C standard requires it. * keyboard.c (read_char): Remove unused var. * eval.c: Port to Windows vsnprintf (Bug#8435). Include . (SIZE_MAX): Define if the headers do not. (verror): Do not give up if vsnprintf returns a negative count. Instead, grow the buffer. This ports to Windows vsnprintf, which does not conform to C99. Problem reported by Eli Zaretskii. Also, simplify the allocation scheme, by avoiding the need for calling realloc, and removing the ALLOCATED variable. * eval.c (verror): Initial buffer size is 4000 (not 200) bytes. Remove invocations of doprnt, as Emacs now uses vsnprintf. But keep the doprint source code for now, as we might revamp it and use it again (Bug#8435). * lisp.h (doprnt): Remove. * Makefile.in (base_obj): Remove doprnt.o. * deps.mk (doprnt.o): Remove. error: Print 32- and 64-bit integers portably (Bug#8435). Without this change, on typical 64-bit hosts error ("...%d...", N) was used to print both 32- and 64-bit integers N, which relied on undefined behavior. * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro. * lisp.h (error, verror): Mark as printf-like functions. * eval.c (verror): Use vsnprintf, not doprnt, to do the real work. Report overflow in size calculations when allocating printf buffer. Do not truncate output string at its first null byte. * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work. Truncate the output at a character boundary, since vsnprintf does not do that. * charset.c (check_iso_charset_parameter): Convert internal character to string before calling 'error', since %c now has the printf meaning. * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int overflow when computing char to be passed to 'error'. Do not pass Lisp_Object to 'error'; pass the integer instead. * nsfns.m (Fns_do_applescript): Use int, not long, since it's formatted with plain %d. * eval.c (internal_lisp_condition_case): Don't pass spurious arg. * keyboard.c (access_keymap_keyremap): Print func name, not garbage. * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int. * xterm.c (x_catch_errors): Remove duplicate declaration. * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too. * xdisp.c, lisp.h (message_nolog): Remove; unused. 2011-04-10 Jim Meyering use ssize_t and size_t for read- and write-like emacs_gnutls_* functions * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like: return ssize_t not "int", and use size_t as the buffer length. (emacs_gnutls_write): Likewise, and make the buffer pointer "const". * gnutls.h: Update declarations. * process.c (read_process_output): Use ssize_t, to match. (send_process): Likewise. 2011-04-09 Chong Yidong * image.c (Fimagemagick_types): Doc fix, and comment cleanup. 2011-04-09 Chong Yidong * ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use unsigned char, to match FcChar8 type definition. * xterm.c (handle_one_xevent): * xmenu.c (create_and_show_popup_menu): * xselect.c (x_decline_selection_request) (x_reply_selection_request): Avoid type-punned deref of X events. 2011-04-09 Eli Zaretskii Fix some uses of `int' instead of EMACS_INT. * search.c (string_match_1, fast_string_match) (fast_c_string_match_ignore_case, fast_string_match_ignore_case) (scan_buffer, find_next_newline_no_quit) (find_before_next_newline, search_command, Freplace_match) (Fmatch_data): Make some `int' variables be EMACS_INT. * xdisp.c (display_count_lines): 3rd argument and return value now EMACS_INT. All callers changed. (pint2hrstr): Last argument is now EMACS_INT. * coding.c (detect_coding_utf_8, detect_coding_emacs_mule) (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5) (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8) (decode_coding_utf_16, decode_coding_emacs_mule) (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5) (decode_coding_ccl, decode_coding_charset) : Declare EMACS_INT.

All users changed. * ccl.c (Fccl_execute_on_string): Declare some variables EMACS_INT. 2011-04-08 Samuel Thibault (tiny change) * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450). 2011-03-19 Christoph Scholtes * process.c (Fformat_network_address): Doc fix. 2011-04-08 T. V. Raman (tiny change) * xml.c (parse_region): Avoid creating spurious whitespace nodes. 2011-04-08 Chong Yidong * keyboard.c (read_char): Call Lisp function help-form-show, instead of using internal_with_output_to_temp_buffer. (Qhelp_form_show): New var. (syms_of_keyboard): Use DEFSYM macro. * print.c (internal_with_output_to_temp_buffer): Function deleted. * lisp.h (internal_with_output_to_temp_buffer): Remove prototype. 2011-04-06 Chong Yidong * process.c (Flist_processes): Remove to Lisp. (list_processes_1): Delete. 2011-04-06 Eli Zaretskii * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements. * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs. 2011-04-06 Paul Eggert Fix more problems found by GCC 4.6.0's static checks. * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats. * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats. * lisp.h (message, message_nolog, fatal): Mark as printf-like. * xdisp.c (vmessage): Mark as a printf-like function. * term.c (vfatal, maybe_fatal): Mark as printf-like functions. * sound.c (sound_warning): Don't crash if arg contains a printf format. * image.c (tiff_error_handler, tiff_warning_handler): Mark as printf-like functions. (tiff_load): Add casts to remove these marks before passing them to system-supplied API. * eval.c (Fsignal): Remove excess argument to 'fatal'. * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int. This avoids several warnings with gcc -Wstrict-overflow. (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code directly, rather than having caller test rule sign. This avoids some unnecessary tests. * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro. (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This affects only one use, in DECODE_COMPOSITION_RULE, which is changed. * xfont.c (xfont_text_extents): Remove var that was set but not used. (xfont_open): Avoid unnecessary tests. * composite.c (composition_gstring_put_cache): Use unsigned integer. * composite.h, composite.c (composition_gstring_put_cache): Use EMACS_INT, not int, for length. * composite.h (COMPOSITION_DECODE_REFS): New macro, breaking out part of COMPOSITION_DECODE_RULE. (COMPOSITION_DECODE_RULE): Use it. * composite.c (get_composition_id): Remove unused local vars, by using the new macro. * textprop.c (set_text_properties_1): Change while to do-while, since the condition is always true at first. * intervals.c (graft_intervals_into_buffer): Mark var as used. (interval_deletion_adjustment): Return unsigned value. All uses changed. * process.c (list_processes_1, create_pty, read_process_output): (exec_sentinel): Remove vars that were set but not used.

(read_process_output): Simplify nbytes computation if buffered. * bytecode.c (exec_byte_code): Rename local to avoid shadowing. * syntax.c (scan_words): Remove var that was set but not used. (update_syntax_table): Use unsigned instead of int. * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs. (lisp_file_lexically_bound_p, read1): Use unsigned instead of int. (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop. * print.c (print_error_message): Avoid int overflow. * font.c (font_list_entities): Redo for clarity, so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX. * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.

(sxhash): Redo loop for clarity and to avoid wraparound warning. * eval.c (funcall_lambda): Rename local to avoid shadowing. * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int. Otherwise, GCC 4.6.0 optimizes the loop check away since the check can always succeed if overflow has undefined behavior. * search.c (boyer_moore, wordify): Remove vars set but not used. (wordify): Omit three unnecessary tests. * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column. All callers changed.

(Finsert_file_contents): Remove unnecessary code checking fd. * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes. Check for integer overflow on size calculations. * buffer.c (Fprevious_overlay_change): Remove var that is set but not used. * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt): Remove vars that are set but not used. (timer_check_2): Don't assume timer-list and idle-timer-list are lists. (timer_check_2): Mark vars as initialized. * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized. * image.c (lookup_image): Remove var that is set but not used. (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable. * fontset.c (Finternal_char_font, Ffontset_info): Remove vars that are set but not used. * xfns.c (make_invisible_cursor): Don't return garbage if XCreateBitmapFromData fails (Bug#8410). * xselect.c (x_get_local_selection, x_handle_property_notify): Remove vars that are set but not used. * xfns.c (x_create_tip_frame): Remove var that is set but not used.

(map_tty_color) [!defined MSDOS]: Likewise. * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning. * coding.c: Remove vars that are set but not used. (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused. All callers changed. (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule): (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5): (decode_coding_charset): Remove vars that are set but not used. * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var that is set but not used. * print.c (print_object): Remove var that is set but not used. Replace 2 copies of readlink code with 1 gnulib version (Bug#8401). The gnulib version avoids calling malloc in the usual case, and on 64-bit hosts doesn't have some arbitrary 32-bit limits. * fileio.c (Ffile_symlink_p): Use emacs_readlink. * filelock.c (current_lock_owner): Likewise. * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function. * sysdep.c: Include allocator.h, careadlinkat.h. (emacs_no_realloc_allocator): New static constant. (emacs_readlink): New function. * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on ../lib/careadlinkat.h. 2011-04-04 Stefan Monnier * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the first non-nil return value). 2011-04-03 Jan Djärv * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6 if not defined (Bug#8403). 2011-04-02 Juanma Barranquero * xdisp.c (display_count_lines): Remove parameter `start', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed. (get_char_face_and_encoding): Remove parameter `multibyte_p', unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed. (fill_stretch_glyph_string): Remove parameters `row' and `area', unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk and thereabouts. All callers changed. (get_per_char_metric): Remove parameter `f', unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed. 2011-04-02 Jim Meyering do not dereference NULL upon failed strdup * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup. (ns_get_family): Likewise. 2011-04-02 Juanma Barranquero * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment. 2011-04-02 Jan Djärv * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or later (Bug#8403). 2011-04-01 Stefan Monnier Add lexical binding. * window.c (Ftemp_output_buffer_show): New fun. (Fsave_window_excursion): * print.c (Fwith_output_to_temp_buffer): Move to subr.el. * lread.c (lisp_file_lexically_bound_p): New function. (Fload): Bind Qlexical_binding. (readevalloop): Remove `evalfun' arg. Bind Qinternal_interpreter_environment. (Feval_buffer): Bind Qlexical_binding. (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard): Mark as dynamic. (syms_of_lread): Declare `lexical-binding'. * lisp.h (struct Lisp_Symbol): New field `declared_special'. * keyboard.c (eval_dyn): New fun. (menu_item_eval_property): Use it. * image.c (parse_image_spec): Use Ffunctionp. * fns.c (concat, mapcar1): Accept byte-code-functions. * eval.c (Fsetq): Handle lexical vars. (Fdefun, Fdefmacro, Ffunction): Make closures when needed. (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic. (FletX, Flet): Obey lexical binding. (Fcommandp): Handle closures. (Feval): New `lexical' arg. (eval_sub): New function extracted from Feval. Use it almost everywhere where Feval was used. Look up vars in lexical env. Handle closures. (Ffunctionp): Move from subr.el. (Ffuncall): Handle closures. (apply_lambda): Remove `eval_flags'. (funcall_lambda): Handle closures and new byte-code-functions. (Fspecial_variable_p): New function.

Add new byte-codes. * buffer.c (defvar_per_buffer): Set new `declared_special' field. * alloc.c (Fmake_symbol): Init new `declared_special' field. 2011-03-31 Juanma Barranquero * xdisp.c (redisplay_internal): Fix prototype. 2011-03-31 Eli Zaretskii * xdisp.c (SCROLL_LIMIT): New macro. (try_scrolling): Use it when setting scroll_limit. Limit scrolling to 100 screen lines. (redisplay_window): Even when falling back on "recentering", position point in the window according to scroll-conservatively, scroll-margin, and scroll-*-aggressively variables. (Bug#6671) (try_scrolling): When point is above the window, allow searching as far as scroll_max, or one screenful, to compute vertical distance from PT to the scroll margin position. This prevents try_scrolling from unnecessarily failing when scroll-conservatively is set to a value slightly larger than the window height. Clean up the case of PT below the margin at bottom of window: scroll_max can no longer be INT_MAX. When aggressive scrolling is in use, don't let point enter the opposite scroll margin as result of the scroll. (syms_of_xdisp) : Document the threshold of 100 lines for never-recentering scrolling. 2011-03-31 Juanma Barranquero * dispextern.h (move_it_by_lines): * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed. (message_log_check_duplicate): Remove parameters `prev_bol' and `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed. (redisplay_internal): Remove parameter `preserve_echo_area', unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed. * indent.c (Fvertical_motion): * window.c (window_scroll_pixel_based, Frecenter): Don't pass `need_y_p' to `move_it_by_lines'. 2011-03-30 Stefan Monnier * eval.c (struct backtrace): Don't cheat with negative numbers, but do steal a few bits to be more compact. (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace): Remove unneeded casts. * bytecode.c (Fbyte_code): CAR and CDR can GC. 2011-03-30 Zachary Kanfer (tiny change) * keyboard.c (Fexecute_extended_command): Do log the "suggest key binding" message (bug#7967). 2011-03-30 Paul Eggert Fix more problems found by GCC 4.6.0's static checks. * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]: Remove unused local var. * editfns.c (Fmessage_box): Remove unused local var. * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs): (note_mode_line_or_margin_highlight, note_mouse_highlight): Omit unused local vars. * window.c (shrink_windows): Omit unused local var. * menu.c (digest_single_submenu): Omit unused local var. * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]: Omit unused local var. * keyboard.c (parse_modifiers_uncached, parse_modifiers): Don't assume string length fits in int. (keyremap_step, read_key_sequence): Use size_t for sizes. (read_key_sequence): Don't check last_real_key_start redundantly. * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA instead of alloca (Bug#8344). * eval.c (Fbacktrace): Don't assume nargs fits in int. (Fbacktrace_frame): Don't assume nframes fits in int. * syntax.c (scan_sexps_forward): Avoid pointer wraparound. * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow concerns. * term.c (produce_glyphless_glyph): Remove unnecessary test. * cm.c (calccost): Turn while-do into do-while, for clarity. * keyboard.c (syms_of_keyboard): Use the same style as later in this function when indexing through an array. This also works around GCC bug 48267. * image.c (tiff_load): Fix off-by-one image count (Bug#8336). * xselect.c (x_check_property_data): Return correct size (Bug#8335). * chartab.c (sub_char_table_ref_and_range): Redo for slight efficiency gain, and to bypass a gcc -Wstrict-overflow warning. * keyboard.c, keyboard.h (num_input_events): Now size_t. This avoids undefined behavior on integer overflow, and is a bit more convenient anyway since it is compared to a size_t variable. Variadic C functions now count arguments with size_t, not int.

(tparm): Make 1st arg a const pointer in decl. Put it at top level. (tparam): Adjust signature to match interface in tparam.h; this removes some undefined behavior. Check that outstring and len are zero, which they always are with Emacs. * tparam.h (PC, BC, UP): New extern decls. * xftfont.c (xftfont_shape): Now static, and defined only if needed.

Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out. * lisp.h (child_setup): Now NO_RETURN unless DOS_NT. This should get cleaned up, so that child_setup has the same signature on all platforms. * callproc.c (call_process_cleanup): Now static. (relocate_fd): Rename locals to avoid shadowing. 2011-03-22 Chong Yidong * xterm.c (x_clear_frame): Remove XClearWindow call.

New file unexec.h, the (simple) interface for unexec (Bug#8267). * unexec.h: New file. * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o): (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o): Depend on unexec.h. * emacs.c [!defined CANNOT_DUMP]: Include unexec.h. * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c: * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

Use functions, not macros, for up- and down-casing (Bug#8254). * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP): (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed to use the following functions instead of these macros. (downcase): Adjust to lack of DOWNCASE_TABLE.

All uses changed. * dired.c (directory_files_internal, file_name_completion): Rename locals to avoid shadowing. Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254). An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in dired.c's scmp function, had undefined behavior. * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP): (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ... * buffer.h: ... to here, because these macros use current_buffer, and the new implementation with inline functions needs to have current_buffer in scope now, rather than later when the macros are used. (downcase, upcase1): New static inline functions. (DOWNCASE, UPCASE1): Reimplement using these functions. This avoids undefined behavior in expressions like DOWNCASE (x) == DOWNCASE (y), which previously suffered from race conditions in accessing the global variables case_temp1 and case_temp2. * casetab.c (case_temp1, case_temp2): Remove; no longer needed. * lisp.h (case_temp1, case_temp2): Remove their decls. * character.h (ASCII_CHAR_P): Move from here ... * lisp.h: ... to here, so that the inline functions mentioned above can use them. * dired.c (directory_files_internal_unwind): Now static. * fileio.c (file_name_as_directory, directory_file_name): (barf_or_query_if_file_exists, auto_save_error, auto_save_1): Now static.

(lock_file_1): Rename local to avoid shadowing. * buffer.c (fix_overlays_before): Mark locals as initialized. (fix_start_end_in_overlays): Likewise. This function should be simplified by using pointers-to-pointers, but that's a different matter. (switch_to_buffer_1): Now static.
