this needed a few ugly tweaks.
this hangs in "make check" now

Adjust comments. - -2013-01-17 Paul Eggert <eggert@cs.ucla.edu> - - 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 <http://bugs.gnu.org/13149#73> and later messages in the thread. - -2013-01-17 Dmitry Antipov <dmantipov@yandex.ru> - - * lisp.h (toplevel): Add comment about using Lisp_Save_Value - objects, related functions and macros. - (make_save_value): Adjust prototype. - (make_save_pointer): New prototype. - (SAFE_NALLOCA): Fix indentation.

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 - <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=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_alloc_image_color, x_create_x_image_and_pixmap, png_load) - (tiff_load, imagemagick_load_image): - Check for overflow in size calculations. - (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.

(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 <inttypes.h>, 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.

This assumption is incorrect + for Emacs, since it type-puns struct Lisp_Vector * with many other + types.
