* Prefer more inline functions in character.hPaul Eggert2020-04-171-0/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/buffer.h (fetch_char_advance, fetch_char_advance_no_check) (buf_next_char_len, next_char_len, buf_prev_char_len) (prev_char_len, inc_both, dec_both): New inline functions, replacing the old character.h macros FETCH_CHAR_ADVANCE, FETCH_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS, INC_POS, BUF_DEC_POS, DEC_POS, INC_BOTH, DEC_BOTH respectively. All callers changed. These new functions all assume buffer primitives and so need to be here rather than in character.h. * src/casefiddle.c (make_char_unibyte): New static function, replacing the old MAKE_CHAR_UNIBYTE macro. All callers changed. (do_casify_unibyte_string): Use SINGLE_BYTE_CHAR_P instead of open-coding it. * src/ccl.c (GET_TRANSLATION_TABLE): New static function, replacing the old macro of the same name. * src/character.c (string_char): Omit 2nd arg. 3rd arg can no longer be NULL. All callers changed. * src/character.h (SINGLE_BYTE_CHAR_P): Move up.

(make_char_multibyte): New static function, replacing the old macro MAKE_CHAR_MULTIBYTE. All callers changed. (CHAR_STRING_ADVANCE): Remove; all callers changed to use CHAR_STRING. (NEXT_CHAR_BOUNDARY): Remove; it was unused. (raw_prev_char_len): New inline function, replacing the old PREV_CHAR_BOUNDARY macro. All callers changed. (string_char_and_length): New inline function, replacing the old STRING_CHAR_AND_LENGTH macro. All callers changed. (STRING_CHAR): Rewrite in terms of string_char_and_length. (string_char_advance): New inline function, replacing the old STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_advance): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE macro. All callers changed. (fetch_string_char_as_multibyte_advance): New inline function, replacing the old FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE macro. All callers changed. (fetch_string_char_advance_no_check): New inline function, replacing the old FETCH_STRING_CHAR_ADVANCE_NO_CHECK macro. All callers changed. * src/regex-emacs.c (HEAD_ADDR_VSTRING): Remove; no longer used. * src/syntax.c (scan_lists): Use dec_bytepos instead of open-coding it. * src/xdisp.c (string_char_and_length): Rename from string_char_and_length to avoid name conflict with new function in character.h. All callers changed.
* Prefer inline functions in character.hPaul Eggert2020-04-171-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In character.h, replace macros with inline functions or enums when this is easy. This improves maintainability and on my platform (Fedora 31 x86-64, gcc -O2) improved CPU performance very slightly (0.3%) on ‘make compile-always’. * src/buffer.h (SANE_TAB_WIDTH, CHARACTER_WIDTH): Move here from character.h, and make them inline functions. Tune CHARACTER_WIDTH so that ASCII_CHAR_WIDTH is no longer needed. (sanitize_tab_width, sanitize_char_width): Move here from character.h. * src/character.h (MAX_CHAR, MAX_UNICODE_CHAR, MAX_1_BYTE_CHAR) (MAX_2_BYTE_CHAR, MAX_3_BYTE_CHAR, MAX_4_BYTE_CHAR) (MAX_5_BYTE_CHAR, MIN_MULTIBYTE_LEADING_CODE) (MAX_MULTIBYTE_LEADING_CODE, MAX_MULTIBYTE_LENGTH): Now enum constants instead of macros. * src/character.h (CHAR_BYTES): Redo to avoid conditional branches. (CHAR_BYTE8_P, BYTE8_TO_CHAR, UNIBYTE_TO_CHAR, CHAR_TO_BYTE8) (CHAR_TO_BYTE_SAFE, CHAR_BYTE8_HEAD_P, CHARACTERP) (CHECK_CHARACTER, CHECK_CHARACTER_CAR, CHECK_CHARACTER_CDR) (CHAR_PRINTABLE_P, CHAR_BYTES, CHAR_LEADING_CODE, BYTE8_STRING) (LEADING_CODE_P, TRAILING_CODE_P, CHAR_HEAD_P) (BYTES_BY_CHAR_HEAD): Now inline functions instead of macros. (ASCII_CHAR_WIDTH): Remove; no longer used. * src/conf_post.h (ATTRIBUTE_PURE): New macro. * src/lisp.h (char_table_ref): Use it, for better inlining. * src/fns.c (base64_decode_1): Add now-necessary casts.
* Remove `all_buffers` and the associated `next` field of buffersStefan Monnier2020-03-311-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | * src/alloc.c (enum mem_type): Remove MEM_TYPE_BUFFER. (allocate_buffer): Allocate like any other pseudovector. Don't register on `all_buffers` any more. (live_buffer_holding, live_buffer_p): Delete functions. (mark_maybe_object, valid_lisp_object_p): Don't pay attention to MEM_TYPE_BUFFER any more. (garbage_collect): Only compact the live buffers. (mark_buffer): Mark the undo_list of dead buffers here. (mark_object): Buffers are normal pseudovectors now. (sweep_buffers): Don't do the actual sweep here, just cleanup the markers and only for live buffers. * src/buffer.c (all_buffers): Remove variable. (Fkill_buffer): Don't check indirect dead buffers. Set the undo_list before we remove ourselves from the list of live buffers. (Fbuffer_swap_text, Fset_buffer_multibyte): Don't check indirect dead buffers. (init_buffer_once): Don't set `all_buffers`. (init_buffer): Don't map new memory for dead buffers. * src/buffer.h (struct buffer): Remove `next` field. (FOR_EACH_BUFFER): Remove macro. * src/pdumper.c (dump_buffer): Don't dump the `next` field.

* | Prefer functions to macros in buffer.hPaul Eggert2019-09-031-266/+395
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In buffer.h, prefer inline functions to function-like macros when either will do. This helps avoid confusion about how many times an arg is evaluated. On my platform, this patch improves performance of ‘make compile-always’ by 5.7%. Also, prefer enum constants to object-like macros when either will do. * src/buffer.h (BEG, BEG_BYTE, GAP_BYTES_DFL, GAP_BYTES_MIN) (MAX_PER_BUFFER_VARS, NONEXISTENT_MODTIME_NSECS) (UNKNOWN_MODTIME_NSECS, BUFFER_LISP_SIZE, BUFFER_REST_SIZE): Now enum constants, instead of macros.

* | Take last_per_buffer_idx privatePaul Eggert2019-09-031-12/+6
|/ | | | | | | | This will simplify future changes. Turn the runtime check into an eassert, since it’s not needed in production. * src/buffer.c (last_per_buffer_idx): Now static. (valid_per_buffer_idx): New function. * src/buffer.h (PER_BUFFER_VALUE_P, SET_PER_BUFFER_VALUE_P): Use it.
* * src/marker.c (buf_bytepos_to_charpos): Re-add the CHAR_HEAD_P assertionStefan Monnier2019-05-071-0/+4
| | | | | | | | | | | | This assertion was removed in 1c349c62305d432abf0fa2b6e3f5d754fe4cab79 because the assumption was invalid during set_intervals_multibyte_1. So we change set_intervals_multibyte_1 to solve the problem in the same way as in the rest of Fset_buffer_multibyte, which actually simplifies the code. * src/buffer.c (advance_to_char_boundary): Not static any more. * src/buffer.h (advance_to_char_boundary): Add prototype. * src/intervals.c (set_intervals_multibyte_1): Use it.
* Allow gap before first non-Lisp pseudovec memberPaul Eggert2019-04-081-8/+6
| | | | | | | | | | | | | Problem reported by Keith David Bershatsky in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00259.html Solution suggested by Stefan Monnier in: https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html * src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE. (BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE. * src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field, not the first non-Lisp field. All callers changed. Callers without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR. (ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.

| | | | | | | | | | | | | | | | | | | | | | | | | Note: portions of this change were mistakenly pushed as part of an unrelated commit a35a1f6a9. * src/buffer.c (Fget_buffer_create): Set inhibit_buffer_hooks non-zero for temporary buffers created by coding.c. Don't run buffer-list-update-hook for such buffers. (Frename_buffer, Fkill_buffer, record_buffer) (Fbury_buffer_internal): Don't run hooks for buffers whose inhibit_buffer_hooks flag is set. * src/buffer.h (struct buffer): New member inhibit_buffer_hooks. * src/pdumper.c (dump_buffer): Dump the new field. Update the hash value in HASH_buffer_XXX. * src/coding.c (make_conversion_work_buffer): Function deleted; code moved to code_conversion_save. (code_conversion_save): Insert code from make_conversion_work_buffer, but arrange for unwind-protecting the current buffer before switching to the work buffer. This avoids leaving reused_workbuf_in_use set if user presses C-g during encoding/decoding. (Vcode_conversion_workbuf_name): Now external variable. * src/coding.h (Vcode_conversion_reused_workbuf): Declare.

* | Use native alignment to access Lisp object dataPaul Eggert2018-06-101-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to tell GCC that P has alignment 8, use (T *) P where T is the type of the pointed-to object, to tell GCC that P has native alignment. This is simpler, matches the intent better, and should help simplify future improvements. Some of these changes are to pacify gcc -Wnull-dereference, since GCC is smarter about pointers now that Emacs no longer uses __builtin_assume_aligned; these minor changes should improve code efficiency slightly. On Fedora 28 x86-64 with default optimization this patch shrinks the size of the Emacs text segment by 0.36%. * src/conf_post.h (__has_builtin, __builtin_assume_aligned): Remove; no longer used. * src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE): Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE and XCDR instead of CDR_SAFE when this is safe. * src/fileio.c (Fexpand_file_name): * src/font.c (clear_font_cache): Pacify -Wnull-dereference by removing unnecessary NILP test. * src/keyboard.c (xevent_start): New function. (read_char, read_key_sequence): Pacify -Wnull-dereference by using xevent_start instead of EVENT_START. * src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro now, since it can no longer be implemented as a function. (XUNTAG): New third argument CTYPE. All uses changed. Cast result to CTYPE * instead of using __builtin_assume_aligned. Simplify by using LISP_WORD_TAG. (LISP_WORD_TAG): New macro. (TAG_PTR): Use it. * src/menu.c (x_popup_menu_1): Pacify -Wnull-dereference by using XCAR instead of Fcar and XCDR instead of Fcdr where this is safe.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-131-1/+1
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

* casing: don’t assume letters are *either* upper- or lower-case (bug#24603)Michal Nazarewicz2017-02-151-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | A compatibility digraph characters, such as Dž, are neither upper- nor lower-case. At the moment however, those are reported as upper-case¹ despite the fact that they change when upper-cased. Stop checking if a character is upper-case before trying to up-case it so that title-case characters are handled correctly. This fixes one of the issues mentioned in bug#24603. ¹ Because they change when converted to lower-case. Notice an asymmetry in that for a character to be considered lower-case it must not be upper-case (plus the usual condition of changing when upper-cased). * src/buffer.h (upcase1): Delete. (upcase): Change to upcase character unconditionally just like downcase does it.

* | Reorder lisp.h to declare types before using themPaul Eggert2016-12-251-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This puts basic functions for types to be after the corresponding type definitions. This is a more-common programming style in C, and will make it easier to port Emacs to gcc -fcheck-pointer-bounds, since the functions now have access to the corresponding types' sizes. This patch does not change the code; it just moves declarations and definitions and removes no-longer-needed forward declarations (Bug#25128). * src/buffer.c, src/data.c, src/image.c: Include process.h, for PROCESSP. * src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER): * src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS): * src/termhooks.h (TERMINALP, XTERMINAL): * src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW): * src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX) (XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR): Move here from lisp.h. * src/intervals.h: Include buffer.h, for BUFFERP. Include lisp.h, for Lisp_Object. * src/lisp.h: Reorder declarations and definitions as described above. Move thread includes to be later, so that they can use the reordered definitions. Move some symbols to other headers (noted elsewhere). Remove forward decls that are no longer needed. * src/thread.h: Include systhread.h here, not in lisp.h, since lisp.h itself does not need systhread.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/thread.c (post_acquire_global_lock): Call set_buffer_internal_2 instead of tricking set_buffer_internal_1 into resetting the current buffer even if it didn't change. This avoids bug#25165, caused by failing to record the modified values of point and mark, because current_buffer was set to NULL. Also, don't bother re-setting the buffer if there was no thread switch, as that just wastes cycles. * src/buffer.c (set_buffer_internal_2): New function, with most of the body of set_buffer_internal_1, but without the test for B being identical to the current buffer. (set_buffer_internal_1): Call set_buffer_internal_2 if B is not identical to the current buffer. * src/buffer.h (set_buffer_internal_2): Add prototype. * test/src/thread-tests.el (thread-sticky-point): New test.

It also introduces #defines for these globals to avoid a monster patch. The #defines mean that this patch also has to rename a few fields whose names clash with the defines. There is currently just a single "thread"; so this patch does not impact Emacs behavior in any significant way.
