26 * character.c (Fstring): Check for size-calculation overflow.
28 * ccl.c: Integer and memory overflow fixes.
29 (Fccl_execute_on_string): Check for memory overflow.
30 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
31 Redo buffer-overflow calculations to avoid integer overflow.
33 * callproc.c (child_setup): Don't assume strlen fits in int.
35 * buffer.c: Memory overflow fixes.
36 (overlays_at, overlays_in, record_overlay_string, overlay_strings):
37 Don't update size of array until after memory allocation succeeds,
38 because xmalloc/xrealloc may not return.
40 * bidi.c: Integer overflow fix.
41 (bidi_shelve_header_size): New constant.
42 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.

45 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
47 Use ptrdiff_t for composition IDs.
48 * character.c (lisp_string_width):
49 * composite.c (composition_table_size, n_compositions)
50 (get_composition_id, composition_gstring_from_id):
51 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
52 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
53 * window.c (Frecenter):
54 Use ptrdiff_t, not int, for composition IDs.
55 * composite.c (get_composition_id): Check for integer overflow.
56 * composite.h: Adjust prototypes to match the above changes.
58 Use ptrdiff_t for hash table indexes.
59 * category.c (hash_get_category_set):
61 * charset.h (struct charset.hash_index, CHECK_CHARSET_GET_ID):
62 * coding.c (coding_system_charset_list, detect_coding_system):
63 * coding.h (struct coding_system.id):
64 * composite.c (get_composition_id, gstring_lookup_cache):
65 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
66 * image.c (xpm_get_color_table_h):
67 * lisp.h (hash_lookup, hash_put):
68 * minibuf.c (Ftest_completion):
69 Use ptrdiff_t for hash table indexes, not int (which is too
70 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
71 32-bit --with-wide-int hosts).
73 * charset.c (Fdefine_charset_internal): Check for integer overflow.
74 Add a FIXME comment about memory leaks.
75 (syms_of_charset): Don't assume xmalloc returns.
77 Don't assume that stated character widths fit in int.
78 * character.c (Fchar_width, c_string_width, lisp_string_width):
79 * character.h (CHAR_WIDTH):
80 * indent.c (MULTIBYTE_BYTES_WIDTH):
81 Use sanitize_char_width to avoid undefined and/or bad behavior
82 with outlandish widths.
83 * character.h (sanitize_tab_width): Renamed from sanitize_width,
84 now that we have two such functions. All uses changed.
85 (sanitize_char_width): New inline function.
87 Don't assume that tab-width fits in int.
88 * character.h (sanitize_width): New inline function.
89 (SANE_TAB_WIDTH): New macro.
90 (ASCII_CHAR_WIDTH): Use it.
91 * indent.c (sane_tab_width): Remove. All uses replaced by
92 SANE_TAB_WIDTH (current_buffer).
93 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
95 * fileio.c: Integer overflow issues with file modes.
96 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
98 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
99 Remove unreachable code.
100 (read_hex, load_charset_map_from_file): Check for integer overflow.
102 * xterm.c: don't go over XClientMessageEvent limit
103 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
104 (x_send_scroll_bar_event): Likewise. Check that the size does not
105 exceed limits imposed by XClientMessageEvent, as well as the usual
106 ptrdiff_t and size_t limits.
108 * keyboard.c: Overflow, signedness and related fixes.
109 (make_lispy_movement): Use same integer type in forward decl
110 that is used in the definition.
111 (read_key_sequence, keyremap_step):
112 Change bufsize argument back to int, undoing my 2011-03-30 change.
113 We prefer signed types, and int is wide enough here.
114 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
115 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
116 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
117 length, not size_t. Use ptrdiff_t for index, not int.
118 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
119 possibility of integer overflow.
121 Overflow, signedness and related fixes for images.
123 * dispextern.h (struct it.stack[0].u.image.image_id)
124 (struct_it.image_id, struct image.id, struct image_cache.size)
125 (struct image_cache.used, struct image_cache.ref_count):
126 * gtkutil.c (update_frame_tool_bar):
127 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
128 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
129 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
130 * nsmenu.m (update_frame_tool_bar):
131 * xdisp.c (calc_pixel_width_or_height):
132 * xfns.c (image_cache_refcount):
133 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
134 on typical 64-bit hosts.
136 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
137 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
138 Omit unnecessary casts to int.
139 (parse_image_spec): Check that integers fall into 'int' range
140 when the callers expect that.
141 (image_ascent): Redo ascent calculation to avoid int overflow.
142 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
143 (lookup_image): Remove unnecessary tests.
144 (xbm_image_p): Locals are now of int, not EMACS_INT,
145 since parse_image_check makes sure they fit into int.
146 (png_load, gif_load, svg_load_image):
147 Prefer int to unsigned where either will do.
148 (tiff_handler): New function, combining the cores of the
149 old tiff_error_handler and tiff_warning_handler. This
150 function is rewritten to use vsnprintf and thereby avoid
151 stack buffer overflows. It uses only the features of vsnprintf
152 that are common to both POSIX and native Microsoft.
153 (tiff_error_handler, tiff_warning_handler): Use it.
154 (tiff_load, gif_load, imagemagick_load_image):
155 Don't assume :index value fits in 'int'.
156 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
157 (imagemagick_load_image): Check that crop parameters fit into
158 the integer types that MagickCropImage accepts. Don't assume
159 Vimagemagick_render_type has a nonnegative value. Don't assume
160 size_t fits in 'long'.
161 (gs_load): Use printmax_t to print the widest integers possible.
162 Check for integer overflow when computing image height and width.
164 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
166 Integer signedness and overflow and related fixes. (Bug#9079)
168 * bidi.c: Integer size and overflow fixes.
169 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
170 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
171 (bidi_cache_find_level_change, bidi_cache_ensure_space)
172 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
173 (bidi_find_other_level_edge):
174 Use ptrdiff_t instead of EMACS_INT where either will do.
175 This works better on 32-bit hosts configured --with-wide-int.
176 (bidi_cache_ensure_space): Check for size-calculation overflow.
177 Use % rather than repeated addition, for better worst-case speed.
178 Don't set bidi_cache_size until after xrealloc returns, because it
180 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
181 (bidi_cache_ensure_space): Also check that the bidi cache size
182 does not exceed that of the largest Lisp string or buffer. See Eli
183 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
185 * alloc.c (__malloc_size_t): Remove.
186 All uses replaced by size_t. See Andreas Schwab's note
187 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
189 * image.c: Improve checking for integer overflow.
190 (check_image_size): Assume that f is nonnull, since
191 it is always nonnull in practice. This is one less thing to
192 worry about when checking for integer overflow later.
193 (x_check_image_size): New function, which checks for integer
194 overflow issues inside X.
195 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
196 This removes the need for a memory_full check.
197 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
198 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
199 (xbm_read_bitmap_data): Change locals back to 'int', since
200 their values must fit in 'int'.
201 (xpm_load_image, png_load, tiff_load):
202 Invoke x_create_x_image_and_pixmap earlier,
203 to avoid much needless work if the image is too large.
204 (tiff_load): Treat overly large images as if
205 x_create_x_image_and_pixmap failed, not as malloc failures.
206 (gs_load): Use x_check_image_size.
208 * gtkutil.c: Omit integer casts.
209 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
210 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
212 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
214 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
215 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
216 would wrongly return t on a 64-bit host.
218 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
219 The plain *_OVERFLOW macros run afoul of GCC bug 49705
220 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
221 and therefore cause GCC to emit a bogus diagnostic in some cases.
223 * image.c: Integer signedness and overflow and related fixes.
224 This is not an exhaustive set of fixes, but it's time to
225 record what I've got.
226 (lookup_pixel_color, check_image_size): Remove redundant decls.
227 (check_image_size): Don't assume that arbitrary EMACS_INT values
228 fit in 'int', or that arbitrary 'double' values fit in 'int'.
229 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
230 (tiff_load, imagemagick_load_image):
231 Check for overflow in size calculations.
232 (x_create_x_image_and_pixmap): Remove unnecessary test for
233 xmalloc returning NULL; that can't happen.
234 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
235 (xpm_color_bucket): Use better integer hashing function.
236 (xpm_cache_color): Don't possibly over-allocate memory.
237 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
239 Use ptrdiff_t, not int or size_t, to record sizes.
240 (png_load): Don't assume values greater than 2**31 fit in 'int'.
241 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
242 either works, as we prefer signed integers.
243 (tiff_read_from_memory, tiff_write_from_memory):
244 Return tsize_t, not size_t, since that's what the TIFF API wants.
245 (tiff_read_from_memory): Don't fail simply because the read would
246 go past EOF; instead, return a short read.
247 (tiff_load): Omit no-longer-needed casts.
248 (Fimagemagick_types): Don't assume size fits into 'int'.
250 Improve hashing quality when configured --with-wide-int.
251 * fns.c (hash_string): New function, taken from sxhash_string.
252 Do not discard information about ASCII character case; this
253 discarding is no longer needed.
254 (sxhash-string): Use it. Change sig to match it. Caller changed.
255 * lisp.h: Declare it.
256 * lread.c (hash_string): Remove, since we now use fns.c's version.
257 The fns.c version returns a wider integer if --with-wide-int is
258 specified, so this should help the quality of the hashing a bit.
260 * emacs.c: Integer overflow minor fix.
261 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
262 Define only if GNU_LINUX.
263 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
265 * dispnew.c: Integer signedness and overflow fixes.
266 Remove unnecessary forward decls, that were a maintenance hassle.
267 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
269 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
270 (scrolling_window): Use ptrdiff_t, not int, for byte count.
271 (prepare_desired_row, line_draw_cost):
272 Use int, not unsigned, where either works.
273 (save_current_matrix, restore_current_matrix):
274 Use ptrdiff_t, not size_t, where either works.
275 (init_display): Check for overflow more accurately, and without
276 relying on undefined behavior.
278 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
279 Remove, replacing with the new symbols in lisp.h. All uses changed.
280 * fileio.c (make_temp_name):
281 * filelock.c (lock_file_1, lock_file):
282 * xdisp.c (message_dolog):
283 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
284 Use pMd etc. instead.
285 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
286 replacing the pWIDE etc. symbols removed from editfns.c.
288 * keyboard.h (num_input_events): Now uintmax_t.
289 This is (very slightly) less likely to mess up due to wraparound.
292 * buffer.c: Integer signedness fixes.
293 (alloc_buffer_text, enlarge_buffer_text):
294 Use ptrdiff_t rather than size_t when either will do, as we prefer
297 * alloc.c: Integer signedness and overflow fixes.
298 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
299 (__malloc_size_t): Default to size_t, not to int.
300 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
301 (Fgarbage_collect, mark_object_loop_halt, mark_object):
302 Prefer ptrdiff_t to size_t when either would do, as we prefer
304 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
305 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
306 Now const. Initialize with values that are in range even if char
308 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
309 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
310 These functions do the right thing with sizes > 2**32.
311 (check_depth): Now ptrdiff_t, not int.
312 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
313 Adjust to new way of storing sizes. Check for size overflow bugs
315 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
316 slightly wrong anyway, as it missed one instance of
317 XMALLOC_OVERRUN_CHECK_OVERHEAD.
318 (refill_memory_reserve): Omit needless cast to size_t.
319 (mark_object_loop_halt): Mark as externally visible.
321 * xselect.c: Integer signedness and overflow fixes.
322 (Fx_register_dnd_atom, x_handle_dnd_message):
323 Use ptrdiff_t, not size_t, since we prefer signed.
324 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
325 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
326 x_dnd_atoms_size and x_dnd_atoms_length.
328 * doprnt.c: Prefer signed to unsigned when either works.
332 * xdisp.c (vmessage):
333 Use ptrdiff_t, not size_t, when using or implementing doprnt,
334 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
335 prefer signed arithmetic to avoid comparison confusion.
336 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
339 Assume freestanding C89 headers, string.h, stdlib.h.
340 * data.c, doprnt.c, floatfns.c, print.c:
341 Include float.h unconditionally.
342 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
343 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
344 * regex.c: Likewise for stddef.h, string.h.
345 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
346 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
347 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
348 (STDC_HEADERS): Remove obsolete defines.
349 * sysdep.c: Include limits.h unconditionally.
351 Assume support for memcmp, memcpy, memmove, memset.
352 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
353 * regex.c (memcmp, memcpy):
354 Remove; we assume C89 now.
356 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
357 (__malloc_safe_bcopy): Remove; no longer needed.
359 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
360 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
361 well either way, and we prefer signed to unsigned.
363 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
366 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
367 and the surrounding thread.
368 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
369 rather than fgets, and retry after EINTR. Otherwise, 'emacs
370 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
372 * s/openbsd.h (BROKEN_SIGIO): Define.
373 * unexelf.c (unexec) [__OpenBSD__]:
374 Don't update the .mdebug section of the Alpha COFF symbol table.
376 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
378 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
381 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
383 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
384 This fixes some race conditions on the permissions of any newly
387 * alloc.c (valid_pointer_p): Use pipe, not open.
388 This fixes some permissions issues when debugging.
390 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
391 If fchown fails to set both uid and gid, try to set just gid,
392 as that is sometimes allowed. Adjust the file's mode to eliminate
393 setuid or setgid bits that are inappropriate if fchown fails.
395 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
397 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
398 to compare Lisp_Objects.
399 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
400 global_gnutls_log_level, don't mistake it for a Lisp_Object.
401 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
403 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
405 * lread.c (read_integer): Unread even EOF character.
406 (read1): Likewise. Properly record start position of symbol.
408 * lread.c (read1): Read `#:' as empty uninterned symbol if no
409 symbol character follows.
411 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
413 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
414 This works around a problem with the previous change to Fcopy_file.
415 Recent glibc declares fchown with __attribute__((warn_unused_result)),
416 and without this change, GCC might complain about discarding
417 fchown's return value.
419 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
421 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
423 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
425 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
427 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
429 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
430 it's used from the C level.
432 * process.c: Use the same condition for POLL_FOR_INPUT in both
433 keyboard.c and process.c (bug#1858).
435 2011-07-09 Lawrence Mitchell <wence@gmx.li>
437 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
438 (Fgnutls_boot): Use it.
440 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
442 * doc.c (Fsubstitute_command_keys): Revert last change.
444 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
446 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
447 quotes the next character, and doesn't affect other longer
448 sequences (bug#8935).
450 * lread.c (syms_of_lread): Clarify that is isn't only
451 `eval-buffer' and `eval-defun' that's affected by
452 `lexical-binding' (bug#8460).
454 2011-07-15 Eli Zaretskii <eliz@gnu.org>
456 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
457 bidi redisplay when a line includes both an image and is
460 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
462 Fix minor problems found by static checking.
463 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
464 (elsz): Now a signed constant, not a size_t var. We prefer signed

1032 Random fixes. E.g., (random) never returned negative values.
1033 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1034 subseconds part to the entropy, as that's a bit more random.
1035 Prefer signed to unsigned, since the signedness doesn't matter and
1036 in general we prefer signed. When given a limit, use a
1037 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1038 latter isn't right if USE_2_TAGS_FOR_INTS.
1039 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1040 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1053 This is more efficient than Ffile_directory_p and avoids a minor race.
1055 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1057 * buffer.c (Foverlay_put): Say what the return value is
1060 * fileio.c (barf_or_query_if_file_exists): Check first if the file
1061 is a directory before asking whether to use the file name
1063 (barf_or_query_if_file_exists): Make the "File is a directory"
1064 error be more correct.
1066 * fns.c (Frequire): Remove the mention of the .gz files, since
1067 that's installation-specific, but keep the mention of
1068 `get-load-suffixes'.
1070 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1072 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1083 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

1185 * eval.c (struct backtrace): Simplify and port the data structure.
1186 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1187 signed bit field, as this assumption is not portable and it makes
1188 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1189 "char debug_on_exit : 1" as this is not portable either; instead,
1190 use the portable "unsigned int debug_on_exit : 1". Remove unused
1191 member evalargs. Remove obsolete comments about cc bombing out.

1409 The following patches are for when GLYPH_DEBUG && !XASSERT.
1410 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1411 * dispnew.c (flush_stdout):
1412 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1413 Mark as externally visible.
1414 * dispnew.c (check_window_matrix_pointers): Now static.
1415 * dispnew.c (window_to_frame_vpos):
1416 * xfns.c (unwind_create_frame):
1417 * xterm.c (x_check_font): Remove unused local.
1418 * scroll.c (CHECK_BOUNDS):
1419 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1420 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1421 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1422 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1423 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1425 (debug_method_add): Use va_list and vsprintf rather than relying
1426 on undefined behavior with wrong number of arguments.
1427 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1428 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1429 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1430 since we're not interested in debugging glyphs with old libraries.
1431 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1432 GCC 4.6.0's static checking.
1434 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1436 Integer overflow and signedness fixes (Bug#8873).
1437 A few related buffer overrun fixes, too.
1439 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
1441 * dispextern.h (struct face.stipple):
1442 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
1443 (x_bitmap_mask, x_allocate_bitmap_record)
1444 (x_create_bitmap_from_data, x_create_bitmap_from_file)
1445 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
1446 (x_create_bitmap_from_xpm_data):
1447 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
1448 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1450 * xfaces.c (load_pixmap):
1451 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1452 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1453 (.bitmaps_last, struct x_output.icon_bitmap):
1454 Use ptrdiff_t, not int, for bitmap indexes.
1455 (x_allocate_bitmap_record): Check for size overflow.
1456 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1458 Use ptrdiff_t, not int, for overlay counts.
1459 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1460 * editfns.c (overlays_around, get_pos_property):
1461 * textprop.c (get_char_property_and_overlay):
1462 * xdisp.c (next_overlay_change, note_mouse_highlight):
1463 * xfaces.c (face_at_buffer_position):
1464 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1465 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1466 (Fnext_overlay_change, Fprevious_overlay_change)
1467 (mouse_face_overlay_overlaps, Foverlays_in):
1468 Use ptrdiff_t, not int, for sizes.
1469 (overlays_at, overlays_in): Check for size-calculation overflow.
1471 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1473 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1474 (x_session_initialize): Do not assume string length fits in int.
1476 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1477 This is unlikely, but can occur if DPI is outlandish.
1479 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1480 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1482 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1483 * xrdb.c (magic_file_p, search_magic_path):
1484 Omit last arg SUFFIX; it was always 0. All callers changed.
1485 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1487 * xfont.c (xfont_match): Avoid need for strlen.
1489 * xfns.c: Don't assume strlen fits in int.
1490 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1492 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1493 not unsigned long, as we prefer signed integers. All callers changed.
1494 Detect integer overflow in repeat count.
1495 (message_dolog): Don't assume print length fits in 39 bytes.
1496 (display_mode_element): Don't assume strlen fits in int.
1498 * termcap.c: Don't assume sizes fit in int and never overflow.
1499 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1500 (gobble_line): Check for size-calculation overflow.
1502 * minibuf.c (Fread_buffer):
1503 * lread.c (intern, intern_c_string):
1504 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1505 Don't assume string length fits in int.
1507 * keyboard.c (parse_tool_bar_item):
1508 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1510 * font.c: Don't assume string length fits in int.
1511 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1512 Use ptrdiff_t, not int.
1513 (font_intern_prop): Don't assume string length fits in int.
1514 Don't assume integer property fits in fixnum.
1515 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1517 * filelock.c: Fix some buffer overrun and integer overflow issues.
1518 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1519 Reformulate so as not to need the command string.
1520 Invoke gzip -cd rather than gunzip, as it's more portable.
1521 (lock_info_type, lock_file_1, lock_file):
1522 Don't assume pid_t and time_t fit in unsigned long.
1523 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1524 (current_lock_owner): Prefer signed type for sizes.
1525 Use memcpy, not strncpy, where memcpy is what is really wanted.
1526 Don't assume (via atoi) that time_t and pid_t fit in int.
1527 Check for time_t and/or pid_t out of range, e.g., via a network share.
1528 Don't alloca where an auto var works fine.
1530 * fileio.c: Fix some integer overflow issues.
1531 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1532 Don't assume string length fits in int.
1533 (directory_file_name): Don't assume string length fits in long.
1534 (make_temp_name): Don't assume pid fits in int, or that its print
1535 length is less than 20.
1537 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1539 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1541 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1543 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1544 We prefer signed integers, even for size calculations.
1546 * emacs.c: Don't assume string length fits in 'int'.
1547 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1548 (main): Don't invoke strlen when not needed.
1550 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1551 (XD_DEBUG_MESSAGE): Don't waste a byte.
1553 * callproc.c (getenv_internal_1, getenv_internal)
1555 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1557 * lread.c (invalid_syntax): Omit length argument.
1558 All uses changed. This doesn't fix a bug, but it simplifies the
1559 code away from its former Hollerith-constant appearance, and it's
1560 one less 'int' to worry about when looking at integer-overflow issues.
1561 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1563 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1564 This didn't break anything, but it didn't help either.
1565 It's confusing to put a bogus integer in a place where the actual
1566 value does not matter.
1567 (LIST_END_P): Remove unused macro and its bogus comment.
1568 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1570 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1571 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1573 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1574 We prefer signed types, and the value cannot exceed the EMACS_INT
1575 range anyway (because otherwise the length would not be representable).
1576 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1577 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1578 This avoids a GCC warning when WIDE_EMACS_INT.
1580 * indent.c (sane_tab_width): New function.
1581 (current_column, scan_for_column, Findent_to, position_indentation)
1582 (compute_motion): Use it. This is just for clarity.
1583 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1585 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1587 * lisp.h (lint_assume): New macro.
1588 * composite.c (composition_gstring_put_cache):
1589 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1591 * editfns.c, insdel.c:
1592 Omit unnecessary forward decls, to simplify future changes.
1594 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1596 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1598 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1599 Use much-faster test for byte-length change.
1600 Don't assume string byte-length fits in 'int'.
1601 Check that character arg fits in 'int'.
1602 (mapcar1): Declare byte as byte, for clarity.
1604 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1606 * fns.c (concat): Catch string overflow earlier.
1607 Do not rely on integer wraparound.
1609 * dispextern.h (struct it.overlay_strings_charpos)
1610 (struct it.selective): Now EMACS_INT, not int.
1611 * xdisp.c (forward_to_next_line_start)
1612 (back_to_previous_visible_line_start)
1613 (reseat_at_next_visible_line_start, next_element_from_buffer):
1614 Don't arbitrarily truncate the value of 'selective' to int.
1616 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1618 * composite.c: Don't truncate sizes to 'int'.
1619 (composition_gstring_p, composition_reseat_it)
1620 (composition_adjust_point): Use EMACS_INT, not int.
1621 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1622 not EMACS_UINT, for indexes.
1624 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1626 * buffer.c: Include <verify.h>.
1627 (struct sortvec.priority, struct sortstr.priority):
1628 Now EMACS_INT, not int.
1629 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1630 (struct sortstr.size, record_overlay_string)
1631 (struct sortstrlist.size, struct sortlist.used):
1632 Don't truncate size to int.
1633 (record_overlay_string): Check for size-calculation overflow.
1634 (init_buffer_once): Check at compile-time, not run-time.
1636 2011-06-22 Jim Meyering <meyering@redhat.com>
1638 Don't leak an XBM-image-sized buffer
1639 * image.c (xbm_load): Free the image buffer after using it.
1641 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1644 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1645 that Sun C diagnosed.
1646 * fns.c (secure_hash): Fix pointer signedness issue.
1647 * intervals.c (static_offset_intervals): New function.
1648 (offset_intervals): Use it.
1650 2011-06-21 Leo Liu <sdl.web@gmail.com>
1653 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1656 * fns.c (secure_hash): Rename from crypto_hash_function and change
1657 the first arg to accept symbols.
1658 (Fsecure_hash): New primitive.
1659 (syms_of_fns): New symbols.
1661 2011-06-20 Deniz Dogan <deniz@dogan.se>
1663 * process.c (Fset_process_buffer): Clarify return value in
1666 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1668 * dispnew.c (add_window_display_history): Use BVAR.
1670 * xdisp.c (debug_method_add): Use BVAR.
1671 (check_window_end, dump_glyph_matrix, dump_glyph)
1672 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1674 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1677 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1678 check till after the cache is created in init_frame_faces.
1680 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1682 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1684 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1686 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1687 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1688 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1690 Improve buffer-overflow checking (Bug#8873).
1691 * fileio.c (Finsert_file_contents):
1692 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1693 Remove the old (too-loose) buffer overflow checks.
1694 They weren't needed, since make_gap checks for buffer overflow.
1695 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1696 The old code merely checked for Emacs fixnum overflow, and relied
1697 on undefined (wraparound) behavior. The new code avoids undefined
1698 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1700 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1701 Tune. Don't use wider integers than needed. Don't use alloca.
1702 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1704 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1706 * insdel.c, lisp.h (buffer_overflow): New function.
1707 (insert_from_buffer_1, replace_range, replace_range_2):
1708 * insdel.c (make_gap_larger):
1709 * editfns.c (Finsert_char):
1710 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1712 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1714 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1716 Integer overflow and signedness fixes (Bug#8873).
1718 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1719 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1721 * fileio.c: Don't assume EMACS_INT fits in off_t.
1722 (emacs_lseek): New static function.
1723 (Finsert_file_contents, Fwrite_region): Use it.
1724 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1726 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1728 * fns.c: Don't overflow int when computing a list length.
1729 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1730 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1731 truncation on 64-bit hosts. Check for QUIT every
1732 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1733 faster and is responsive enough.
1734 (Flength): Report an error instead of overflowing an integer.
1735 (Fsafe_length): Return a float if the value is not representable
1736 as a fixnum. This shouldn't happen except in contrived situations.
1737 (Fnthcdr, Fsort): Don't assume list length fits in int.
1738 (Fcopy_sequence): Don't assume vector length fits in int.
1740 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1741 (header_size, word_size): New constants.
1742 (allocate_vectorlike): Don't check size overflow here.
1743 (allocate_vector): Check it here instead, since this is the only
1744 caller of allocate_vectorlike that could cause overflow.
1745 Check that the new vector's length is representable as a fixnum.
1747 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1748 The previous code was bogus. For example, next_almost_prime (32)
1749 returned 39, which is undesirable as it is a multiple of 3; and
1750 next_almost_prime (24) returned 25, which is a multiple of 5 so
1751 why was the code bothering to check for multiples of 7?
1753 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1755 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1757 Variadic C functions now count arguments with ptrdiff_t.
1758 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1759 Back then I didn't know that the Emacs coding style prefers signed int.
1760 Also, in the meantime I found a few more instances where arguments
1761 were being counted with int, which may truncate counts on 64-bit
1762 machines, or EMACS_INT, which may be unnecessarily wide.
1763 * lisp.h (struct Lisp_Subr.function.aMANY)
1764 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1765 Arg counts are now ptrdiff_t, not size_t.
1766 All variadic functions and their callers changed accordingly.
1767 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1768 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1769 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1770 * callint.c (Fcall_interactively): Check arg count for overflow,
1771 to avoid potential buffer overrun. Use signed char, not 'int',
1772 for 'varies' array, so that we needn't bother to check its size
1773 calculation for overflow.
1774 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1775 * eval.c (apply_lambda):
1776 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1777 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1778 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1780 * callint.c (Fcall_interactively): Don't use index var as event count.
1782 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1783 * mem-limits.h (SIZE): Remove; no longer used.
1785 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1787 Remove unnecessary casts.
1788 * xterm.c (x_term_init):
1789 * xfns.c (x_set_border_pixel):
1790 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1791 These aren't needed now that we assume ANSI C.
1793 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1794 It's more likely to cause problems (due to unsigned overflow)
1797 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1799 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1801 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1803 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1805 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1807 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1809 GLYPH_CODE_FACE returns EMACS_INT, not int.
1810 * dispextern.h (merge_faces):
1811 * xfaces.c (merge_faces):
1812 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1813 Don't assume EMACS_INT fits in int.
1815 * character.h (CHAR_VALID_P): Remove unused parameter.
1816 * fontset.c, lisp.h, xdisp.c: All uses changed.
1818 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1820 * fns.c (concat): Minor tuning based on overflow analysis.
1821 This doesn't fix any bugs. Use int to hold character, instead
1822 of constantly refetching from Emacs object. Use XFASTINT, not
1823 XINT, for value known to be a character. Don't bother comparing
1824 a single byte to 0400, as it's always less.
1826 * floatfns.c (Fexpt):
1827 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1829 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1832 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1834 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1835 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1836 incorrectly succeed when S was a string, because 4294967386 was
1837 truncated before it was used.
1839 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1840 Otherwise, an out-of-range integer could cause undefined behavior
1843 * composite.c: Use int, not EMACS_INT, for characters.
1844 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1845 EMACS_INT, for values that are known to be in character range.
1846 This doesn't fix any bugs but is the usual style inside Emacs and
1847 may generate better code on 32-bit machines.
1849 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1850 This is for reasons similar to the recent CHAR_STRING fix.
1851 * charset.c (Fencode_char): Check that character arg is actually
1852 a character. Pass an int to ENCODE_CHAR.
1853 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1854 wider than 'int', as a compile-time check to prevent future regressions
1857 * character.c (char_string): Remove unnecessary casts.
1859 Make sure a 64-bit char is never passed to CHAR_STRING.
1860 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1861 by silently ignoring the top 32 bits, allowing some values
1862 that were far too large to be valid characters.
1863 * character.h: Include <verify.h>.
1864 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1865 arguments are no wider than unsigned, as a compile-time check
1866 to prevent future regressions in this area.
1868 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1869 (Fsubst_char_in_region):
1871 * xdisp.c (decode_mode_spec_coding):
1872 Adjust to CHAR_STRING's new requirement.
1873 * editfns.c (Finsert_char, Fsubst_char_in_region):
1874 * fns.c (concat): Check that character args are actually
1875 characters. Without this test, these functions did the wrong
1876 thing with wildly out-of-range values on 64-bit hosts.
1878 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
1879 These casts should not be needed on 32-bit hosts, either.
1880 * keyboard.c (read_char):
1881 * lread.c (Fload): Remove casts to unsigned.
1883 * lisp.h (UNSIGNED_CMP): New macro.
1884 This fixes comparison bugs on 64-bit hosts.
1885 (ASCII_CHAR_P): Use it.
1886 * casefiddle.c (casify_object):
1887 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
1888 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
1889 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
1890 * dispextern.h (FACE_FROM_ID):
1891 * keyboard.c (read_char): Use UNSIGNED_CMP.
1893 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
1894 not to EMACS_INT, to avoid GCC warning.
1896 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
1898 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
1899 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
1900 isn't needed on 32-bit machines.
1902 * buffer.c (Fgenerate_new_buffer_name):
1903 Use EMACS_INT for count, not int.
1904 (advance_to_char_boundary): Return EMACS_INT, not int.
1906 * data.c (Qcompiled_function): Now static.
1908 * window.c (window_body_lines): Now static.
1910 * image.c (gif_load): Rename local to avoid shadowing.
1912 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
1913 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
1914 * alloc.c (make_save_value): Integer argument is now of type
1916 (mark_object): Use ptrdiff_t, not int.
1917 * lisp.h (pD): New macro.
1918 * print.c (print_object): Use it.
1920 * alloc.c: Use EMACS_INT, not int, to count objects.
1921 (total_conses, total_markers, total_symbols, total_vector_size)
1922 (total_free_conses, total_free_markers, total_free_symbols)
1923 (total_free_floats, total_floats, total_free_intervals)
1924 (total_intervals, total_strings, total_free_strings):
1925 Now EMACS_INT, not int. All uses changed.
1926 (Fgarbage_collect): Compute overall total using a double, so that
1927 integer overflow is less likely to be a problem. Check for overflow
1928 when converting back to an integer.
1929 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
1930 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
1931 These were 'int' variables that could overflow on 64-bit hosts;
1932 they were never used, so remove them instead of repairing them.
1933 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
1934 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
1935 Previously, this ceilinged at INT_MAX, but that doesn't work on
1937 (allocate_pseudovector): Don't use EMACS_INT when int would do.
1939 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
1940 (allocate_vectorlike): Check for ptrdiff_t overflow.
1941 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
1942 when a (possibly-narrower) signed value would do just as well.
1943 We prefer using signed arithmetic, to avoid comparison confusion.
1945 * alloc.c: Catch some string size overflows that we were missing.
1946 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
1947 for convenience in STRING_BYTES_MAX.
1948 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
1949 The definition here is exact; the one in lisp.h was approximate.
1950 (allocate_string_data): Check for string overflow. This catches
1951 some instances we weren't catching before. Also, it catches
1952 size_t overflow on (unusual) hosts where SIZE_MAX <= min
1953 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
1954 and ptrdiff_t and EMACS_INT are both 64 bits.
1956 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
1957 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
1958 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
1960 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
1962 * alloc.c (Fmake_string): Check for out-of-range init.
1964 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
1966 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

1970 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
1971 xg_get_default_scrollbar_width.

1979 Call gtk_window_set_resizable if HAVE_GTK3.
1980 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
1981 and height if HAVE_GTK3 (Bug#8505).
1982 (scroll_bar_width_for_theme): New variable.
1983 (update_theme_scrollbar_width): New function.
1984 (xg_get_default_scrollbar_width): Move code to
1985 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
1986 (xg_initialize): Call update_theme_scrollbar_width.

2542 (bidi_resolve_explicit, bidi_resolve_weak)
2543 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
2544 bidi_it->nchars is non-positive.
2545 (bidi_level_of_next_char): Don't try to lookup the cache for the

2563 last portion of handle_display_prop.
2564 (compute_display_string_pos): Accept additional argument
2565 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2566 value of a `display' property is a "replacing spec".
2567 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2568 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

2596 All callers changed. (Bug#8762)
2598 * gnutls.c: Use Emacs's memory allocators.
2599 Without this change, the gnutls library would invoke malloc etc.
2600 directly, which causes problems on non-SYNC_INPUT hosts, and which
2601 runs afoul of improving memory_full behavior. (Bug#8761)
2602 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2603 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2604 xfree instead of the default malloc, realloc, free.
2605 (Fgnutls_boot): No need to check for memory allocation failure,
2606 since xmalloc does that for us.

2632 * ccl.c (ccl_driver):
2633 Check for overflow when converting EMACS_INT to int.
2634 * fns.c, image.c: Remove unnecessary static decls that would otherwise

2637 Check for integer overflow with large hash tables.
2638 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2639 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2640 (SXHASH_REDUCE): New macro.
2641 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2642 Use it instead of discarding useful hash info with large hash values.
2643 (sxhash_float): New function.
2644 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2645 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2646 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2647 Rewrite to use FIXNUM_BITS, as this simplifies things.
2648 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2649 Adjust signatures to match updated version of code.
2650 (consing_since_gc): Now EMACS_INT, since a single hash table can

2700 Make it possible to run ./temacs.
2702 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2703 syms_of_callproc does the same thing. Remove test for
2704 "initialized", do it in the caller.
2705 * emacs.c (main): Avoid calling set_initial_environment when dumping.
2707 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

2776 * dbusbind.c: Serial number integer overflow fixes.
2777 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2778 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2779 to hold a serial number that is too large for a fixnum.
2780 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2781 Check for serial numbers out of range. Decode any serial number
2782 that was so large that it became a float. (Bug#8722)
2784 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2785 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2786 Use XFASTINT rather than XUINT when numbers are nonnegative.
2787 (xd_append_arg, Fdbus_method_return_internal):
2788 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2789 arguments, check that Lisp number is nonnegative, rather than
2790 silently wrapping negative numbers around. (Bug#8722)
2791 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2794 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2796 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2798 ccl: add integer overflow checks
2799 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2800 (IN_INT_RANGE): New macros.
2801 (ccl_driver): Use them to check for integer overflow when
2802 decoding a CCL program. Many of the new checks are whether XINT (x)
2803 fits in int; it doesn't always, on 64-bit hosts. The new version
2804 doesn't catch all possible integer overflows, but it's an
2805 improvement. (Bug#8719)
2807 * alloc.c (make_event_array): Use XINT, not XUINT.
2808 There's no need for unsigned here.
2810 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2811 This follows up to the 2011-05-06 change that substituted uintptr_t
2812 for EMACS_INT. This case wasn't caught back then.
2814 Rework Fformat to avoid integer overflow issues.
2815 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2816 now (part of C89). Include <verify.h>.
2817 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2818 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2819 (Fformat): Avoid the prepass trying to compute sizes; it was only
2820 approximate and thus did not catch overflow reliably. Instead, walk
2821 through the format just once, formatting and computing sizes as we go,
2822 checking for integer overflow at every step, and allocating a larger
2823 buffer as needed. Keep track separately whether the format is
2824 multibyte. Keep only the most-recently calculated precision, rather
2825 than them all. Record whether each argument has been converted to
2826 string. Use EMACS_INT, not int, for byte and char and arg counts.
2827 Support field widths and precisions larger than INT_MAX. Avoid
2828 sprintf's undefined behavior with conversion specifications such as %#d
2829 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2830 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2831 formatting out-of-range floating point numbers with int
2834 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2836 * data.c: Avoid integer truncation in expressions involving floats.
2837 * data.c: Include <intprops.h>.
2838 (arith_driver): When there's an integer overflow in an expression
2839 involving floating point, convert the integers to floating point
2840 so that the resulting value does not suffer from catastrophic
2841 integer truncation. For example, on a 64-bit host (* 4
2842 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2843 Do not rely on undefined behavior after integer overflow.
2845 merge count_size_as_multibyte, parse_str_to_multibyte
2846 * character.c, character.h (count_size_as_multibyte):
2847 Rename from parse_str_to_multibyte; all uses changed.
2848 Check for integer overflow.
2849 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2850 since it's now a duplicate of the other. This is more of
2851 a character than a buffer op, so better that it's in character.c.
2852 * fns.c, print.c: Adjust to above changes.
2854 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2856 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2858 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2860 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2861 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2862 (x_clipboard_manager_save): Now static.
2863 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2865 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2866 (crypto_hash_function): Now static.
2867 Fix pointer signedness problems. Avoid unnecessary initializations.
2869 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2871 * termhooks.h (Vselection_alist): Make it terminal-local.
2873 * terminal.c (create_terminal): Initialize it.
2875 * xselect.c: Support for clipboard managers.
2876 (Vselection_alist): Move to termhooks.h as terminal-local var.
2877 (LOCAL_SELECTION): New macro.
2878 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
2879 (symbol_to_x_atom): Remove gratuitous arg.
2880 (x_handle_selection_request, lisp_data_to_selection_data)
2881 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
2882 (x_own_selection, x_get_local_selection, x_convert_selection):
2883 New arg, specifying work frame. Use terminal-local Vselection_alist.
2884 (some_frame_on_display): Delete unused function.
2885 (Fx_own_selection_internal, Fx_get_selection_internal)
2886 (Fx_disown_selection_internal, Fx_selection_owner_p)
2887 (Fx_selection_exists_p): New optional frame arg.
2888 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
2889 (x_handle_selection_clear): Don't treat other terminals with the
2890 same keyboard specially. Use the terminal-local Vselection_alist.
2891 (x_clear_frame_selections): Use Frun_hook_with_args.
2893 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
2895 * xterm.h: Add support for those atoms.
2897 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
2899 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
2900 (converted_selections, conversion_fail_tag): New global variables.
2901 (x_selection_request_lisp_error): Free the above.
2902 (x_get_local_selection): Remove unnecessary code.
2903 (x_reply_selection_request): Args changed; handle arbitrary array
2904 of converted selections stored in converted_selections.
2905 Separate the XChangeProperty and SelectionNotify steps.
2906 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
2907 (x_convert_selection): New function.
2908 (x_handle_selection_event): Simplify.
2909 (x_get_foreign_selection): Don't ignore incoming requests while
2910 waiting for an answer; this will fail when we implement
2911 SAVE_TARGETS, and seems unnecessary anyway.
2912 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
2913 (Vx_sent_selection_functions): Doc fix.
2915 2011-05-26 Leo Liu <sdl.web@gmail.com>
2917 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
2919 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2921 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
2923 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
2924 for fringe update if it has periodic bitmap.
2925 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
2926 and fringe_bitmap_periodic_p.
2928 * fringe.c (get_fringe_bitmap_data): New function.
2929 (draw_fringe_bitmap_1, update_window_fringes): Use it.
2930 (update_window_fringes): Record periodicity of fringe bitmap in glyph
2931 row. Mark glyph row for fringe update if periodicity changed.
2933 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
2934 for fringe update unless it has periodic bitmap.
2936 2011-05-25 Kenichi Handa <handa@m17n.org>
2938 * xdisp.c (get_next_display_element): Set correct it->face_id for
2939 a static composition.
2941 2011-05-24 Leo Liu <sdl.web@gmail.com>
2944 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
2946 * fns.c (crypto_hash_function, Fsha1): New function.
2947 (Fmd5): Use crypto_hash_function.
2948 (syms_of_fns): Add Ssha1.
2950 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2952 * gnutls.c: Remove unused macros.
2953 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
2954 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
2955 Remove macros that are defined and never used.
2956 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
2958 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2960 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
2961 (Fx_get_selection_internal): Minor cleanup.
2962 (Fx_own_selection_internal): Rename arguments for consistency with
2965 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2967 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
2969 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2971 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
2973 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2975 * dispnew.c (scrolling_window): Don't exclude the case that the
2976 last enabled row in the desired matrix touches the bottom boundary.
2978 2011-05-21 Glenn Morris <rgm@gnu.org>
2980 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
2981 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
2982 and add some more files.
2984 2011-05-20 Eli Zaretskii <eliz@gnu.org>
2986 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
2987 report_file_error introduced by the change from 2011-05-07.
2989 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
2991 * systime.h (Time): Define only if emacs is defined.
2992 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
2993 where the include path doesn't have X11/X.h by default. See
2994 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
2996 2011-05-20 Kenichi Handa <handa@m17n.org>
2998 * composite.c (find_automatic_composition): Fix previous change.
3000 2011-05-20 Glenn Morris <rgm@gnu.org>
3002 * lisp.mk: New file, split from Makefile.in.
3003 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3004 (shortlisp): Remove.
3005 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3007 2011-05-19 Glenn Morris <rgm@gnu.org>
3009 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3010 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3011 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3012 (lisp): Set the order to that of loadup.el.
3013 (shortlisp): Make it a copy of $lisp.
3014 (SOME_MACHINE_LISP): Remove.
3015 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3016 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3018 2011-05-18 Kenichi Handa <handa@m17n.org>
3020 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3021 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3022 (find_automatic_composition): Mostly rewrite for efficiency.
3024 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3026 * makefile.w32-in: Update dependencies.
3028 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3030 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3031 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3033 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3035 Fix some integer overflow issues, such as string length overflow.
3037 * insdel.c (count_size_as_multibyte): Check for string overflow.
3039 * character.c (lisp_string_width): Check for string overflow.
3040 Use EMACS_INT, not int, for string indexes and lengths; in
3041 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3042 the resulting string length overflows an EMACS_INT; instead,
3043 report a string overflow if no precision given. When checking for
3044 precision exhaustion, use a check that cannot possibly have
3045 integer overflow. (Bug#8675)
3046 * character.h (lisp_string_width): Adjust to new signature.
3048 * alloc.c (string_overflow): New function.
3049 (Fmake_string): Use it. This doesn't change behavior, but saves
3050 a few bytes and will simplify future changes.
3051 * character.c (string_escape_byte8): Likewise.
3052 * lisp.h (string_overflow): New decl.
3054 Fixups, following up to the user-interface timestamp change.
3055 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3056 for UI timestamps, instead of unsigned long.
3057 * msdos.c (mouse_get_pos): Likewise.
3058 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3059 * w32gui.h (Time): Define by including "systime.h" rather than by
3060 declaring it ourselves. (Bug#8664)
3062 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3063 * image.c (clear_image_cache): Likewise.
3065 * term.c (term_mouse_position): Don't assume time_t wraparound.
3067 Be more systematic about user-interface timestamps.
3068 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3069 and sometimes 'EMACS_UINT', to represent these timestamps.
3070 This change causes it to use 'Time' uniformly, as that's what X uses.
3071 This makes the code easier to follow, and makes it easier to catch
3072 integer overflow bugs such as Bug#8664.
3073 * frame.c (Fmouse_position, Fmouse_pixel_position):
3074 Use Time, not unsigned long, for user-interface timestamps.
3075 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3076 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3077 * keyboard.h (last_event_timestamp): Likewise.
3078 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3079 * menu.h (xmenu_show): Likewise.
3080 * term.c (term_mouse_position): Likewise.
3081 * termhooks.h (struct input_event.timestamp): Likewise.
3082 (struct terminal.mouse_position_hook): Likewise.
3083 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3084 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3085 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3086 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3088 * menu.h, termhooks.h: Include "systime.h", for Time.
3090 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3091 Don't assume that the difference between two unsigned long values
3092 can fit into an integer. At this point, we know button_down_time
3093 <= event->timestamp, so the difference must be nonnegative, so
3094 there's no need to cast the result if double-click-time is
3095 nonnegative, as it should be; check that it's nonnegative, just in
3096 case. This bug is triggered when events are more than 2**31 ms
3097 apart (about 25 days). (Bug#8664)
3099 * xselect.c (last_event_timestamp): Remove duplicate decl.
3100 (x_own_selection): Remove needless cast to unsigned long.
3102 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3103 that always fit in int. Use a sentinel instead of a counter, to
3104 avoid a temp and to allay GCC's concerns about possible int overflow.
3105 * frame.h (struct frame): Use int for menu_bar_items_used
3106 instead of EMACS_INT, since it always fits in int.
3108 * menu.c (grow_menu_items): Check for int overflow.
3110 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3112 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3113 Before, the code was not consistent. These values cannot exceed
3114 2**31 - 1 so there's no need to make them unsigned.
3115 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3116 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3117 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3119 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3121 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3122 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3123 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3124 presumably because the widths might not match.
3126 * window.c (size_window): Avoid needless test at loop start.
3128 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3130 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3132 2011-05-12 Drew Adams <drew.adams@oracle.com>
3134 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3136 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3138 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3139 `width' to `bar_area_x' and `bar_area_width', respectively.
3140 (x_scroll_run): Take account of fringe background extension.
3142 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3143 Rename local vars `left' and `width' to `bar_area_x' and
3144 `bar_area_width', respectively.
3145 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3146 background extension.
3148 2011-05-10 Jim Meyering <meyering@redhat.com>
3150 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3152 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3154 * image.c (Finit_image_library): Return t for built-in image types,
3155 like pbm and xbm. (Bug#8640)
3157 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3159 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3161 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3163 * w32console.c (Fset_screen_color): Doc fix.
3164 (Fget_screen_color): New function.
3165 (syms_of_ntterm): Defsubr it.
3167 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3168 unlink the temporary file if Fcall_process didn't create it in the
3170 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3171 child process will be redirected to a file specified with `:file'.
3172 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3173 cue to call_process_cleanup not to close that handle.
3175 2011-05-07 Ben Key <bkey76@gmail.com>
3177 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3178 one of two shell specific rules, either bootstrap-temacs-CMD or
3179 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3180 to the previous implementation of the bootstrap-temacs rule.
3181 The bootstrap-temacs-CMD rule is similar to the previous
3182 implementation of the bootstrap-temacs rule except that it
3183 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3186 These changes, along with some changes to nt/configure.bat,
3187 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3188 earlier fix to add support for --cflags and --ldflags options
3189 that include quotes so that it works whether make uses cmd or
3192 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3194 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3195 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3197 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3198 a string. Handle both cases.
3199 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3200 (Fdbus_register_method): Use Qinvalid_function.
3202 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3204 * makefile.w32-in: Update dependencies.
3205 (LISP_H): Add inttypes.h and stdin.h.
3206 (PROCESS_H): Add unistd.h.
3208 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3210 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3211 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3213 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3215 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3217 * term.c (vfatal): Remove stray call to va_end.
3218 It's not needed and the C Standard doesn't allow it here anyway.
3220 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3221 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3223 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3226 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3228 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3230 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3232 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3234 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3236 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3237 * charset.c (Fdefine_charset_internal): Don't initialize
3238 charset.code_space[15]. The value was garbage, on hosts with
3239 32-bit int (Bug#8600).
3241 * lread.c (read_integer): Be more consistent with string-to-number.
3242 Use string_to_number to do the actual conversion; this avoids
3243 rounding errors and fixes some other screwups. Without this fix,
3244 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3245 (digit_to_number): Move earlier, for benefit of read_integer.
3246 Return -1 if the digit is out of range for the base, -2 if it is
3247 not a digit in any supported base. (Bug#8602)
3249 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3251 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3252 to match comment at start of function. This also removes a
3253 GCC warning about overflow in a 32+64-bit port.
3255 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3257 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3258 Reported by Stefan Monnier in
3259 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3260 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3261 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3263 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3264 (EMACS_UINTPTR): Likewise, with uintptr_t.
3266 * lisp.h: Prefer 64-bit EMACS_INT if available.
3267 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3268 on 32-bit hosts that have 64-bit int, so that they can access
3270 However, temporarily disable this change unless the temporary
3271 symbol WIDE_EMACS_INT is defined.
3273 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3275 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3276 This removes an assumption that EMACS_INT and long are the same
3277 width as pointers. The assumption is true for Emacs porting targets
3278 now, but we want to make other targets possible.
3279 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3280 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3281 In the rest of the code, change types of integers that hold casted
3282 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3283 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3284 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3285 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3286 No need to cast type when ORing.
3287 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3288 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3289 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3290 assume EMACS_INT is the same width as char *.
3291 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3292 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3293 Remove no-longer-needed casts.
3294 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3295 (xg_tool_bar_help_callback, xg_make_tool_item):
3296 Use EMACS_INTPTR to hold an integer
3297 that will be cast to void *; this can avoid a GCC warning
3298 if EMACS_INT is not the same width as void *.
3299 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3300 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3301 (current_message_1, set_message_1):
3302 Use a local to convert to proper width without a cast.
3303 * xmenu.c (dialog_selection_callback): Likewise.
3305 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3306 Also, don't assume VALBITS / RAND_BITS is less than 5,
3307 and don't rely on undefined behavior when shifting a 1 left into
3309 * lisp.h (get_random): Change signature to match.
3311 * lread.c (hash_string): Use size_t, not int, for hash computation.
3312 Normally we prefer signed values; but hashing is special, because
3313 it's better to use unsigned division on hash table sizes so that
3314 the remainder is nonnegative. Also, size_t is the natural width
3315 for hashing into memory. The previous code used 'int', which doesn't
3316 retain enough info to hash well into very large tables.
3317 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3319 * dbusbind.c: Don't possibly lose pointer info when converting.
3320 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3321 Use XPNTR rather than XHASH, so that the high-order bits of
3322 the pointer aren't lost when converting through void *.
3324 * eval.c (Fautoload): Don't double-shift a pointer.
3326 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3328 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3330 * gnutls.c (DEF_GNUTLS_FN):
3331 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3333 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3335 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3338 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3340 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3341 New version that can reserve upto 2GB of heap space.
3343 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3345 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3347 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3349 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3350 `gnutls_certificate_set_x509_key_file'.
3352 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3354 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3355 Update dependencies.
3357 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3359 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3360 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3361 Remove unused parameter `fildes'.
3362 * process.c (read_process_output, send_process): Don't pass it.
3364 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3366 Fix previous change: the library cache is defined in w32.c.
3367 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3368 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3370 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3372 Implement dynamic loading of GnuTLS on Windows.
3374 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
3375 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3376 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3379 * gnutls.c (Qgnutls_dll): Define.
3380 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3381 (gnutls_*): Declare function pointers.
3382 (init_gnutls_functions): New function to initialize function pointers.
3383 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3384 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3385 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3386 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3387 (emacs_gnutls_write, emacs_gnutls_read)
3388 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3389 (Fgnutls_available_p): New function.
3390 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3391 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3392 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3394 * image.c: Include w32.h.
3395 (Vimage_type_cache): Delete.
3396 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3397 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3398 (w32_delayed_load): Move to w32.c.
3400 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3402 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3403 (w32_delayed_load): Move from image.c. When loading a library, record
3404 its filename in the :loaded-from property of the library id.
3405 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3406 Initialize and staticpro them.
3407 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3409 * process.c: Include lisp.h before w32.h, not after.
3410 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3411 instead of gnutls_record_check_pending.
3413 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3415 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
3417 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3418 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3421 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
3423 * xterm.c (x_set_frame_alpha): Do not set property on anything
3424 else than FRAME_X_OUTER_WINDOW (Bug#8608).
3426 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3428 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
3430 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3432 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
3433 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
3434 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

3439 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
3440 (Qgnutls_bootprop_callbacks_verify): Make static.
3442 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
3444 * callproc.c: Indentation fixup.
3446 * sysdep.c (wait_for_termination_1): Make static.
3447 (wait_for_termination, interruptible_wait_for_termination):
3448 Move after wait_for_termination_1.
3450 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
3452 * sysdep.c (interruptible_wait_for_termination): New function
3453 which is like wait_for_termination, but allows keyboard
3456 * callproc.c (Fcall_process): Add (:file "file") as an option for
3458 (Fcall_process_region): Ditto.
3460 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3462 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3463 rather than `XVECTOR (FOO)->size'.
3465 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3466 inttypes.h, as a gnulib replacement is used if it not available in
3469 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3471 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3472 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3473 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3475 * coding.c (coding_alloc_by_realloc): Error out if destination
3476 will grow beyond MOST_POSITIVE_FIXNUM.
3477 (decode_coding_emacs_mule): Abort if there isn't enough place in
3478 charbuf for the composition carryover bytes. Reserve an extra
3479 space for up to 2 characters produced in a loop.
3480 (decode_coding_iso_2022): Abort if there isn't enough place in
3481 charbuf for the composition carryover bytes.
3483 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3485 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3486 aborting when %lld or %lll format is passed.
3487 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3488 %llo or %llx format is passed. (Bug#8545)
3490 * window.c (window_scroll_line_based): Use a marker instead of
3491 simple variables to record original value of point. (Bug#7952)
3493 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3494 produced by %s or %c overflows available buffer space. (Bug#8545)
3496 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3498 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3499 (SIZE_MAX): Move defn after all includes, as they might #define it.
3501 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3503 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3505 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3507 * keyboard.c (Qdelayed_warnings_hook): Define.
3508 (command_loop_1): Run `delayed-warnings-hook'
3509 if Vdelayed_warnings_list is non-nil.
3510 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3511 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3513 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3515 * doprnt.c (doprnt): Don't return value smaller than the buffer
3516 size if the message was truncated. (Bug#8545).
3518 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3520 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
3521 (Fx_window_property): #if-0 the whole functions, not just the bodies.
3523 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3525 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3527 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3529 * makefile.w32-in: Update dependencies.
3531 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3533 Improve `doprnt' and its usage. (Bug#8545)
3534 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3535 `format_end'. Remove support for %l as a conversion specifier.
3536 Don't use xrealloc. Improve diagnostics when the %l size modifier
3537 is used. Update the commentary.
3539 * eval.c (verror): Simplify calculation of size_t.
3541 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3544 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3546 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3549 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3551 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3552 This makes this file independent of the recent pseudovector change.
3554 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3556 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3558 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3559 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3560 Remove unused local.
3561 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3563 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3564 GCC 4.6.0 optimizes based on type-based alias analysis.
3565 For example, if b is of type struct buffer * and v of type struct
3566 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3567 != &v->size, and therefore "v->size = 1; b->size = 2; return
3568 v->size;" must therefore return 1. This assumption is incorrect
3569 for Emacs, since it type-puns struct Lisp_Vector * with many other
3570 types. To fix this problem, this patch adds a new type struct
3571 vectorlike_header that documents the constraints on layout of vectors
3572 and pseudovectors, and helps optimizing compilers not get fooled
3573 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3574 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3575 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3577 (XSETPVECTYPE): Rewrite in terms of new macro.
3578 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3579 This is a bit clearer, and further avoids the possibility of
3580 undesirable aliasing.
3581 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3582 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3583 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3584 since Lisp_Subr is a special case (no "next" field).
3585 (ASIZE): Now uses header.size rather than size.
3586 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3587 to avoid the hassle of writing XVECTOR (foo)->header.size.
3588 (struct vectorlike_header): New type.
3589 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3590 object, to help avoid aliasing.
3591 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3592 (SUBRP): Likewise, since Lisp_Subr is a special case.
3593 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3594 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3595 (struct Lisp_Hash_Table): Combine first two members into a single
3596 struct vectorlike_header member. All uses of "size" and "next" members
3597 changed to be "header.size" and "header.next".
3598 * buffer.h (struct buffer): Likewise.
3599 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3600 * frame.h (struct frame): Likewise.
3601 * process.h (struct Lisp_Process): Likewise.
3602 * termhooks.h (struct terminal): Likewise.
3603 * window.c (struct save_window_data, struct saved_window): Likewise.
3604 * window.h (struct window): Likewise.
3605 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3606 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3607 * buffer.c (init_buffer_once): Likewise.
3608 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3610 * process.c (Fformat_network_address): Use local var for size,
3613 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3615 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3616 * data.c (atof): Remove decl; no longer used or needed.
3617 (digit_to_number): Move to lread.c.
3618 (Fstring_to_number): Use new string_to_number function, to be
3619 consistent with how the Lisp reader treats infinities and NaNs.
3620 Do not assume that floating-point numbers represent EMACS_INT
3621 without losing information; this is not true on most 64-bit hosts.
3622 Avoid double-rounding errors, by insisting on integers when
3623 parsing non-base-10 numbers, as the documentation specifies.
3624 * lisp.h (string_to_number): New decl, replacing ...
3625 (isfloat_string): Remove.
3626 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3627 (read1): Do not accept +. and -. as integers; this
3628 appears to have been a coding error. Similarly, do not accept
3629 strings like +-1e0 as floating point numbers. Do not report
3630 overflow for integer overflows unless the base is not 10 which
3631 means we have no simple and reliable way to continue.
3632 Break out the floating-point parsing into a new
3633 function string_to_number, so that Fstring_to_number parses
3634 floating point numbers consistently with the Lisp reader.
3635 (digit_to_number): Move here from data.c. Make it static inline.
3636 (E_CHAR, EXP_INT): Remove, replacing with ...
3637 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3638 (string_to_number): New function, replacing isfloat_string.
3639 This function checks for valid syntax and produces the resulting
3640 Lisp float number too. Rework it so that string-to-number
3641 no longer mishandles examples like "1.0e+". Use strtoumax,
3642 so that overflow for non-base-10 numbers is reported only when
3643 there's no portable and simple way to convert to floating point.
3645 * textprop.c (set_text_properties_1): Rewrite for clarity,
3646 and to avoid GCC warning about integer overflow.
3648 * intervals.h (struct interval): Use EMACS_INT for members
3649 where EMACS_UINT might cause problems. See
3650 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3651 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3652 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3654 (offset_intervals): Tell GCC not to worry about length overflow
3655 when negating a negative length.
3657 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3658 (overrun_check_free): Likewise.
3660 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3661 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3664 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.

3668 Comment out unused local. Fix pointer signedness problems.
3670 * lread.c (openp): Don't stuff size_t into an 'int'.
3671 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3672 about possible signed overflow.
3674 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3675 (GDK_KEY_g): Don't define if already defined.

3679 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3680 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3682 * xfns.c (Fx_window_property): Simplify a bit,
3683 to make a bit faster and to avoid GCC 4.6.0 warning.
3684 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3686 * fns.c (internal_equal): Don't assume size_t fits in int.
3688 * alloc.c (compact_small_strings): Tighten assertion a little.
3690 Replace pEd with more-general pI, and fix some printf arg casts.
3691 * lisp.h (pI): New macro, generalizing old pEd macro to other
3692 conversion specifiers. For example, use "...%"pI"d..." rather
3693 than "...%"pEd"...".
3694 (pEd): Remove. All uses replaced with similar uses of pI.
3695 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.

3699 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3700 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.

3704 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3705 * print.c (safe_debug_print, print_object): Likewise.
3706 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3708 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3709 avoiding the 0 flag, which is not portable.
3710 * process.c (Fmake_network_process): Use pI to avoid cast.
3711 * region-cache.c (pp_cache): Likewise.
3712 * xdisp.c (decode_mode_spec): Likewise.

3717 (x_get_window_property): Don't truncate byte count to an 'int'
3720 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3721 here, since it parses constructs like leading '-' and spaces,
3722 which are not wanted; and it overflows with large numbers.
3723 Instead, simply match F[0-9]+, which is what is wanted anyway.
3725 * alloc.c: Remove unportable assumptions about struct layout.
3726 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3727 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3728 (allocate_vectorlike, make_pure_vector): Use the new macros,
3729 plus offsetof, to remove unportable assumptions about struct layout.
3730 These assumptions hold on all porting targets that I know of, but
3731 they are not guaranteed, they're easy to remove, and removing them
3732 makes further changes easier.
3734 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3735 This doesn't fix a bug but makes the code clearer.
3736 (string_overrun_cookie): Now const. Use initializers that
3737 don't formally overflow signed char, to avoid warnings.
3738 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3739 can cause Emacs to crash when string overrun checking is enabled.
3740 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3741 multiple of sizeof (EMACS_INT); it need not be, if
3742 alignof(EMACS_INT) < sizeof (EMACS_INT).
3743 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
3745 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

3774 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3775 "cast to pointer from integer of different size".
3777 Improve doprnt and its use in verror. (Bug#8545)

3779 supported by the function. Use SAFE_ALLOCA instead of always
3782 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3783 is one byte too soon. Don't use xrealloc; instead xfree and

3896 about invalid control letter, pass the character's codepoint, not
3897 a pointer to its multibyte form. Improve display of the character
3898 in octal and display also its hex code.
3900 * character.c (char_string): Use %x to display the (unsigned)
3901 codepoint of an invalid character, to avoid displaying a bogus
3904 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
3905 `error', not SYMBOL_NAME itself.
3907 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
3908 character arguments to `error'.
3910 * charset.c (check_iso_charset_parameter): Fix incorrect argument
3911 to `error' in error message about FINAL_CHAR argument. Make sure
3912 FINAL_CHAR is a character, and use %c when it is passed as
3913 argument to `error'.

4102 * nsfont.m: Fixed bugs in ns_get_family and
4103 ns_descriptor_to_entity that were caused by using free to
4104 deallocate memory blocks that were allocated by xmalloc (via
4105 xstrdup). This caused Emacs to crash when compiled with
4106 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
4107 --enable-checking=xmallocoverrun). xfree is now used to
4108 deallocate these memory blocks.

4123 Emacs source code has been audited now.
4124 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
4125 (emacs_read, emacs_write): Use it.
4126 * process.c (send_process): Adjust to the new signatures of
4127 emacs_write and emacs_gnutls_write. Do not attempt to store
4128 a byte offset into an 'int'; it might overflow.
4129 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html
4131 * sound.c: Don't assume sizes fit in 'int'.

4583 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4585 * keyboard.c (parse_tool_bar_item): Likewise.
4586 * sound.c (sound_cleanup, alsa_close): Likewise.
4587 * termcap.c (tgetent): Likewise.
4588 * xfns.c (x_default_font_parameter): Likewise.
4589 * xsettings.c (read_and_apply_settings): Likewise.
4591 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4592 (overrun_check_free): Protoize.
4594 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4596 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4597 since callers should never pass a negative size.
4598 Change the signature to match that of plain 'read' and 'write'; see
4599 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4600 * lisp.h: Update prototypes of emacs_write and emacs_read.
4602 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4604 * xdisp.c (redisplay_window): Don't try to determine the character
4605 position of the scroll margin if the window start point w->startp
4606 is outside the buffer's accessible region. (Bug#8468)
4608 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4610 Fix write-region and its subroutines for buffers > 2GB.
4611 * fileio.c (a_write, e_write): Modify declaration of arguments and
4612 local variables to support buffers larger than 2GB.
4613 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4615 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4616 argument, local variables, and return value.
4618 * lisp.h: Update prototypes of emacs_write and emacs_read.
4620 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4622 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4624 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4626 Fix more problems found by GCC 4.6.0's static checks.
4628 * xdisp.c (vmessage): Use a better test for character truncation.
4630 * charset.c (load_charset_map): <, not <=, for optimization,
4631 and to avoid potential problems with integer overflow.
4632 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4633 * casetab.c (set_identity, shuffle): Likewise.
4634 * editfns.c (Fformat): Likewise.
4635 * syntax.c (skip_chars): Likewise.
4637 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4638 This also lets GCC 4.6.0 generate slightly better loop code.
4640 * callint.c (Fcall_interactively): <, not <=, for optimization.
4641 (Fcall_interactively): Count the number of arguments produced,
4642 not the number of arguments given. This is simpler and lets GCC
4643 4.6.0 generate slightly better code.
4645 * ftfont.c: Distingish more carefully between FcChar8 and char.
4646 The previous code passed unsigned char * to a functions like
4647 strlen and xstrcasecmp that expect char *, which does not
4648 conform to the C standard.
4649 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4650 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4651 char * when the C standard requires it.
4653 * keyboard.c (read_char): Remove unused var.
4655 * eval.c: Port to Windows vsnprintf (Bug#8435).
4657 (SIZE_MAX): Define if the headers do not.
4658 (verror): Do not give up if vsnprintf returns a negative count.
4659 Instead, grow the buffer. This ports to Windows vsnprintf, which
4660 does not conform to C99. Problem reported by Eli Zaretskii.
4661 Also, simplify the allocation scheme, by avoiding the need for
4662 calling realloc, and removing the ALLOCATED variable.
4664 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4666 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4667 But keep the doprint source code for now, as we might revamp it
4668 and use it again (Bug#8435).
4669 * lisp.h (doprnt): Remove.
4670 * Makefile.in (base_obj): Remove doprnt.o.
4671 * deps.mk (doprnt.o): Remove.
4673 error: Print 32- and 64-bit integers portably (Bug#8435).
4674 Without this change, on typical 64-bit hosts error ("...%d...", N)
4675 was used to print both 32- and 64-bit integers N, which relied on
4677 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4679 * lisp.h (error, verror): Mark as printf-like functions.
4680 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4681 Report overflow in size calculations when allocating printf buffer.
4682 Do not truncate output string at its first null byte.
4683 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4684 Truncate the output at a character boundary, since vsnprintf does not
4686 * charset.c (check_iso_charset_parameter): Convert internal
4687 character to string before calling 'error', since %c now has the
4689 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4690 overflow when computing char to be passed to 'error'. Do not
4691 pass Lisp_Object to 'error'; pass the integer instead.
4692 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4693 formatted with plain %d.
4695 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4697 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4699 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4701 * xterm.c (x_catch_errors): Remove duplicate declaration.
4703 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4705 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4707 2011-04-10 Jim Meyering <meyering@redhat.com>
4709 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4710 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4711 return ssize_t not "int", and use size_t as the buffer length.
4712 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4713 * gnutls.h: Update declarations.
4714 * process.c (read_process_output): Use ssize_t, to match.
4715 (send_process): Likewise.
4717 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4719 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4721 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4723 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4724 Use unsigned char, to match FcChar8 type definition.
4726 * xterm.c (handle_one_xevent):
4727 * xmenu.c (create_and_show_popup_menu):
4728 * xselect.c (x_decline_selection_request)
4729 (x_reply_selection_request): Avoid type-punned deref of X events.
4731 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4733 Fix some uses of `int' instead of EMACS_INT.
4734 * search.c (string_match_1, fast_string_match)
4735 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4736 (scan_buffer, find_next_newline_no_quit)
4737 (find_before_next_newline, search_command, Freplace_match)
4738 (Fmatch_data): Make some `int' variables be EMACS_INT.
4740 * xdisp.c (display_count_lines): 3rd argument and return value now
4741 EMACS_INT. All callers changed.
4742 (pint2hrstr): Last argument is now EMACS_INT.
4744 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4745 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4746 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
4747 (decode_coding_utf_16, decode_coding_emacs_mule)
4748 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4749 (decode_coding_ccl, decode_coding_charset)
4750 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4751 (decode_coding_iso_2022, decode_coding_emacs_mule)
4752 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4753 <char_offset, last_offset>: Declare EMACS_INT.
4754 (encode_coding_utf_8, encode_coding_utf_16)
4755 (encode_coding_emacs_mule, encode_invocation_designation)
4756 (encode_designation_at_bol, encode_coding_iso_2022)
4757 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4758 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4760 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4761 (encode_invocation_designation): Last argument P_NCHARS is now
4763 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4764 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4766 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4769 * ccl.c (Fccl_execute_on_string): Declare some variables
4772 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
4774 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
4776 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>

4780 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4782 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4784 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4786 * keyboard.c (read_char): Call Lisp function help-form-show,
4787 instead of using internal_with_output_to_temp_buffer.
4788 (Qhelp_form_show): New var.
4789 (syms_of_keyboard): Use DEFSYM macro.
4791 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4793 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4795 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4797 * process.c (Flist_processes): Remove to Lisp.
4798 (list_processes_1): Delete.

4806 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4808 Fix more problems found by GCC 4.6.0's static checks.
4810 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4812 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4814 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4816 * xdisp.c (vmessage): Mark as a printf-like function.
4818 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4820 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4822 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4823 printf-like functions.
4824 (tiff_load): Add casts to remove these marks before passing them
4825 to system-supplied API.
4827 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4829 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4830 This avoids several warnings with gcc -Wstrict-overflow.
4831 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4832 directly, rather than having caller test rule sign. This avoids
4833 some unnecessary tests.
4834 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4835 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4836 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4838 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4839 (xfont_open): Avoid unnecessary tests.
4841 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4850 by using the new macro.
4852 * textprop.c (set_text_properties_1): Change while to do-while,
4853 since the condition is always true at first.
4855 * intervals.c (graft_intervals_into_buffer): Mark var as used.
4856 (interval_deletion_adjustment): Return unsigned value.
4859 * process.c (list_processes_1, create_pty, read_process_output):

4866 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
4868 * syntax.c (scan_words): Remove var that was set but not used.
4869 (update_syntax_table): Use unsigned instead of int.
4871 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
4872 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.

4875 * print.c (print_error_message): Avoid int overflow.
4877 * font.c (font_list_entities): Redo for clarity,
4878 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
4880 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
4881 (font_score): Avoid potential overflow in diff calculation.
4883 * fns.c (substring_both): Remove var that is set but not used.
4884 (sxhash): Redo loop for clarity and to avoid wraparound warning.
4886 * eval.c (funcall_lambda): Rename local to avoid shadowing.
4888 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
4889 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
4890 can always succeed if overflow has undefined behavior.
4892 * search.c (boyer_moore, wordify): Remove vars set but not used.
4893 (wordify): Omit three unnecessary tests.
4895 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
4896 All callers changed. This avoids the need for an unused var.
4898 * casefiddle.c (casify_region): Remove var that is set but not used.
4900 * dired.c (file_name_completion): Remove var that is set but not used.
4902 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
4904 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
4905 (Finsert_file_contents): Remove unnecessary code checking fd.
4907 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
4908 Check for integer overflow on size calculations.
4910 * buffer.c (Fprevious_overlay_change): Remove var that is set
4913 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
4914 Remove vars that are set but not used.
4915 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
4916 (timer_check_2): Mark vars as initialized.
4918 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
4920 * image.c (lookup_image): Remove var that is set but not used.
4921 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
4923 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
4924 that are set but not used.
4926 * xfns.c (make_invisible_cursor): Don't return garbage
4927 if XCreateBitmapFromData fails (Bug#8410).

4930 Remove vars that are set but not used.
4932 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
4933 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
4935 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
4936 Remove var that is set but not used.

4946 * coding.c: Remove vars that are set but not used.
4947 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
4948 All callers changed.
4949 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

4951 (decode_coding_charset): Remove vars that are set but not used.
4953 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
4954 that is set but not used.
4956 * print.c (print_object): Remove var that is set but not used.
4958 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
4959 The gnulib version avoids calling malloc in the usual case,
4960 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
4961 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
4962 * filelock.c (current_lock_owner): Likewise.
4963 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
4964 * sysdep.c: Include allocator.h, careadlinkat.h.
4965 (emacs_no_realloc_allocator): New static constant.
4966 (emacs_readlink): New function.
4967 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
4968 ../lib/careadlinkat.h.
4970 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
4972 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
4973 first non-nil return value).
4975 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
4977 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
4978 if not defined (Bug#8403).
4980 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
4982 * xdisp.c (display_count_lines): Remove parameter `start',
4983 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
4984 (get_char_face_and_encoding): Remove parameter `multibyte_p',
4985 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

4987 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
4988 and thereabouts. All callers changed.
4989 (get_per_char_metric): Remove parameter `f', unused since
4990 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

4994 do not dereference NULL upon failed strdup
4995 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
4996 (ns_get_family): Likewise.
4998 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

5065 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5067 * xdisp.c (redisplay_internal): Fix prototype.
5069 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5071 * xdisp.c (SCROLL_LIMIT): New macro.
5072 (try_scrolling): Use it when setting scroll_limit.
5073 Limit scrolling to 100 screen lines.
5074 (redisplay_window): Even when falling back on "recentering",
5075 position point in the window according to scroll-conservatively,
5076 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5078 (try_scrolling): When point is above the window, allow searching
5079 as far as scroll_max, or one screenful, to compute vertical
5080 distance from PT to the scroll margin position. This prevents
5081 try_scrolling from unnecessarily failing when
5082 scroll-conservatively is set to a value slightly larger than the
5083 window height. Clean up the case of PT below the margin at bottom
5084 of window: scroll_max can no longer be INT_MAX. When aggressive
5085 scrolling is in use, don't let point enter the opposite scroll
5086 margin as result of the scroll.
5087 (syms_of_xdisp) <scroll-conservatively>: Document the
5088 threshold of 100 lines for never-recentering scrolling.
5090 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5092 * dispextern.h (move_it_by_lines):
5093 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5094 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5095 (message_log_check_duplicate): Remove parameters `prev_bol' and
5096 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5097 (redisplay_internal): Remove parameter `preserve_echo_area',
5098 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5100 * indent.c (Fvertical_motion):
5101 * window.c (window_scroll_pixel_based, Frecenter):
5102 Don't pass `need_y_p' to `move_it_by_lines'.
5104 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5106 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5107 steal a few bits to be more compact.
5108 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5109 Remove unneeded casts.
5111 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5113 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5115 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5116 binding" message (bug#7967).
5118 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5120 Fix more problems found by GCC 4.6.0's static checks.
5122 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5123 Remove unused local var.
5125 * editfns.c (Fmessage_box): Remove unused local var.
5127 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5128 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5129 Omit unused local vars.
5130 * window.c (shrink_windows): Omit unused local var.
5131 * menu.c (digest_single_submenu): Omit unused local var.
5132 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5133 Omit unused local var.
5135 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5136 Don't assume string length fits in int.
5137 (keyremap_step, read_key_sequence): Use size_t for sizes.
5138 (read_key_sequence): Don't check last_real_key_start redundantly.
5140 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5141 instead of alloca (Bug#8344).
5143 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5144 (Fbacktrace_frame): Don't assume nframes fits in int.
5146 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

5151 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5153 * cm.c (calccost): Turn while-do into do-while, for clarity.
5155 * keyboard.c (syms_of_keyboard): Use the same style as later
5156 in this function when indexing through an array. This also
5157 works around GCC bug 48267.
5159 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5161 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5163 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5164 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5166 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5167 This avoids undefined behavior on integer overflow, and is a bit
5168 more convenient anyway since it is compared to a size_t variable.
5170 Variadic C functions now count arguments with size_t, not int.
5171 This avoids an unnecessary limitation on 64-bit machines, which
5172 caused (substring ...) to crash on large vectors (Bug#8344).
5173 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5174 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
5175 All variadic functions and their callers changed accordingly.
5176 (struct gcpro.nvars): Now size_t, not int. All uses changed.
5177 * data.c (arith_driver, float_arith_driver): Likewise.
5178 * editfns.c (general_insert_function): Likewise.
5179 * eval.c (struct backtrace.nargs, interactive_p)
5180 (internal_condition_case_n, run_hook_with_args, apply_lambda)
5181 (funcall_lambda, mark_backtrace): Likewise.
5182 * fns.c (concat): Likewise.
5183 * frame.c (x_set_frame_parameters): Likewise.
5184 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5185 0 if not found, not -1. All callers changed.
5187 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5188 (stack_copy_size): Now size_t, not int.
5189 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5191 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5193 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5194 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5195 All callers changed.
5197 * lisp.h (multibyte_char_to_unibyte):
5198 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5199 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5200 * character.h (CHAR_TO_BYTE8):
5201 * cmds.c (internal_self_insert):
5202 * editfns.c (general_insert_function):
5203 * keymap.c (push_key_description):
5204 * search.c (Freplace_match):
5205 * xdisp.c (message_dolog, set_message_1): All callers changed.
5207 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5209 * keyboard.c (safe_run_hook_funcall): New function.
5210 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5211 don't set the hook to nil, but remove the offending function instead.
5212 (Qcommand_hook_internal): Remove, unused.
5213 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5214 Vcommand_hook_internal.
5216 * eval.c (enum run_hooks_condition): Remove.
5217 (funcall_nil, funcall_not): New functions.
5218 (run_hook_with_args): Call each function through a `funcall' argument.
5219 Remove `cond' argument, now redundant.
5220 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
5221 (Frun_hook_with_args_until_failure): Adjust accordingly.
5222 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

5228 * print.c (strout): Remove parameter `multibyte', unused since
5229 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5231 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
5232 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5233 All callers changed.
5235 * w32.c (_wsa_errlist): Use braces for struct initializers.
5237 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5238 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
5239 All callers changed.
5240 (string_buffer_position): Likewise. Also, make static (it's never
5241 used outside xdisp.c).
5242 (cursor_row_p): Remove parameter `w', unused since
5243 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
5244 (decode_mode_spec): Remove parameter `precision', introduced during
5245 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
5246 All callers changed.

5271 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
5272 Replace SIGTYPE with void everywhere.
5273 * s/usg5-4-common.h (SIGTYPE): Remove definition.

5298 * w32menu.c (w32_menu_display_help):
5299 * xmenu.c (show_help_event, menu_help_callback):

5308 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
5309 (gap_left, gap_right): Don't call it.
5311 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
5313 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
5314 incurred during fontification.
5316 2011-03-25 Juanma Barranquero <lekktu@gmail.com>

5394 * buffer.c (Fkill_all_local_variables):
5395 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5397 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5398 unconditionnaly since it does the check itself.
5400 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5402 Fix more problems found by GCC 4.5.2's static checks.
5404 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5405 the first time through the loop, since we know p0 < p1 then.
5406 This also avoids a gcc -Wstrict-overflow warning.
5408 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5409 leading to a memory leak, possible in functions like
5410 load_charset_map_from_file that can allocate an unbounded number
5411 of objects (Bug#8318).
5413 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5414 that could (at least in theory) be that large.
5416 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5417 This is less likely to overflow, and avoids undefined behavior if
5418 overflow does occur. All callers changed. Use strtoul to scan
5419 for the unsigned long integer.
5420 (pint2hrstr): Simplify and tune code slightly.
5421 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5423 * scroll.c (do_scrolling): Work around GCC bug 48228.
5424 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

5427 This also avoids a warning with gcc -Wstrict-overflow.
5428 (validate_x_resource_name): Simplify count usage.
5429 This also avoids a warning with gcc -Wstrict-overflow.
5431 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5434 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5436 * process.c (Fmake_network_process): Use socklen_t, not int,
5437 where POSIX says socklen_t is required in portable programs.
5438 This fixes a porting bug on hosts like 64-bit HP-UX, where
5439 socklen_t is wider than int (Bug#8277).
5440 (Fmake_network_process, server_accept_connection):
5441 (wait_reading_process_output, read_process_output):

5454 Make tparam.h and terminfo.c consistent.
5455 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5456 Include tparam.h instead, since it declares them.
5457 * cm.h (PC): Remove extern decl; tparam.h now does this.
5458 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5459 * terminfo.c: Include tparam.h, to check interfaces.
5460 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5461 (tparam): Adjust signature to match interface in tparam.h;
5462 this removes some undefined behavior. Check that outstring and len
5463 are zero, which they always are with Emacs.
5464 * tparam.h (PC, BC, UP): New extern decls.
5466 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5467 (xftfont_open): Rename locals to avoid shadowing.
5469 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
5470 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
5471 (OTF_TAG_SYM): Omit macro if not needed.
5472 (ftfont_list): Remove unused local.
5473 (get_adstyle_property, ftfont_pattern_entity):
5474 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
5475 Rename locals to avoid shadowing.
5477 * xfont.c (xfont_list_family): Mark var as initialized.
5479 * xml.c (make_dom): Now static.
5481 * composite.c (composition_compute_stop_pos): Rename local to
5483 (composition_reseat_it): Remove unused locals.
5484 (find_automatic_composition, composition_adjust_point): Likewise.
5485 (composition_update_it): Mark var as initialized.
5486 (find_automatic_composition): Mark vars as initialized,
5487 with a FIXME (Bug#8290).
5489 character.h: Rename locals to avoid shadowing.
5490 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
5491 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
5492 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5493 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5496 * textprop.c (property_change_between_p): Remove; unused.
5498 * intervals.c (interval_start_pos): Now static.
5500 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
5502 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
5503 Rename locals to avoid shadowing.
5505 * sound.c (wav_play, au_play, Fplay_sound_internal):
5506 Fix pointer signedness.
5507 (alsa_choose_format): Remove unused local var.
5508 (wav_play): Initialize a variable to 0, to prevent undefined
5509 behavior (Bug#8278).
5511 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5513 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5515 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5516 clobbering (Bug#8298).

5518 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5520 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.

5525 (relocate_fd): Rename locals to avoid shadowing.
5527 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

5694 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5695 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5696 to use the following functions instead of these macros.
5697 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5698 EMACS_INT, since callers assume the returned value fits in int.
5699 (upcase1): Likewise, for UPCASE_TABLE.
5700 (uppercasep, lowercasep, upcase): New static inline functions.
5701 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

5710 which gcc can warn about.
5711 (regex_compile, re_match_2_internal): Mark locals as initialized.
5712 (RETALLOC_IF): Define only if needed.
5713 (WORDCHAR_P): Likewise. This one is never needed, but is used
5714 only in a comment talking about a compiler bug, so put inside
5715 the #if 0 of that comment.
5716 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5717 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5720 * search.c (boyer_moore): Rename locals to avoid shadowing.

5743 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
5744 New macros, so that the caller can use some names other than
5745 gcpro1, gcpro2, etc.
5746 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5748 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5749 argument, for consistency with GCPRO2_VAR, etc: it is now the
5750 prefix of the variable, not the variable itself. All uses
5752 * dired.c (directory_files_internal, file_name_completion):
5753 Rename locals to avoid shadowing.
5755 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5756 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5757 dired.c's scmp function, had undefined behavior.
5758 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5759 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5760 * buffer.h: ... to here, because these macros use current_buffer,
5761 and the new implementation with inline functions needs to have
5762 current_buffer in scope now, rather than later when the macros
5764 (downcase, upcase1): New static inline functions.
5765 (DOWNCASE, UPCASE1): Reimplement using these functions.
5766 This avoids undefined behavior in expressions like
5767 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5768 from race conditions in accessing the global variables
5769 case_temp1 and case_temp2.
5770 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5771 * lisp.h (case_temp1, case_temp2): Remove their decls.
5772 * character.h (ASCII_CHAR_P): Move from here ...
5773 * lisp.h: ... to here, so that the inline functions mentioned
5776 * dired.c (directory_files_internal_unwind): Now static.
5778 * fileio.c (file_name_as_directory, directory_file_name):
5779 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5781 (file_name_as_directory): Use const pointers when appropriate.
5782 (Fexpand_file_name): Likewise. In particular, newdir might
5783 point at constant storage, so make it a const pointer.
5784 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5785 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5787 (Fset_file_times, Finsert_file_contents, auto_save_error):
5788 Rename locals to avoid shadowing.

5796 * lisp.h (verify_bytepos, count_markers): New decls,
5797 so that gcc does not warn that these functions aren't declared.
5799 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5800 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

5805 (lock_file_1): Rename local to avoid shadowing.
5807 * buffer.c (fix_overlays_before): Mark locals as initialized.
5808 (fix_start_end_in_overlays): Likewise. This function should be
5809 simplified by using pointers-to-pointers, but that's a different
5811 (switch_to_buffer_1): Now static.
5812 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5813 (report_overlay_modification): Rename locals to avoid shadowing.
5815 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5816 Fix pointer signedness issue.
5817 (sys_subshell): Mark local as volatile if checking for lint,
5818 to suppress a gcc -Wclobbered warning that does not seem to be right.
5819 (MAXPATHLEN): Define only if needed.
5821 * process.c (serial_open, serial_configure): Move decls from here ...
5822 * systty.h: ... to here, so that they can be checked.
5824 * fns.c (get_random, seed_random): Move extern decls from here ...
5825 * lisp.h: ... to here, so that they can be checked.
5827 * sysdep.c (reset_io): Now static.
5828 (wait_for_termination_signal): Remove; unused.
5830 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

5837 Rename locals to avoid shadowing.
5839 * keyboard.c: Declare functions static if they are not used elsewhere.
5840 (echo_char, echo_dash, cmd_error, top_level_2):
5841 (poll_for_input, handle_async_input): Now static.
5842 (read_char, kbd_buffer_get_event, make_lispy_position):
5843 (make_lispy_event, make_lispy_movement, apply_modifiers):

5986 For example, without this patch (encode-time 0 0 0 1 1
5987 1152921504606846976) returns the obviously-bogus value (-948597
5988 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
5989 reports time overflow. See
