5 Check for integer overflow in size calculations.
7 * fringe.c (Fdefine_fringe_bitmap): Don't update size until alloc works.
9 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
10 This is for the members text_lines, text_cols, total_lines, total_cols,
11 where the system imposes an 'int' limit.
13 * frame.c: Integer overflow fixes.
14 (set_menu_bar_lines, x_set_frame_parameters, x_set_scroll_bar_width)

67 Redo buffer-overflow calculations to avoid integer overflow.
69 * callproc.c (child_setup): Don't assume strlen fits in int.
71 * buffer.c: Memory overflow fixes.
72 (overlays_at, overlays_in, record_overlay_string, overlay_strings):
73 Don't update size of array until after memory allocation succeeds,
74 because xmalloc/xrealloc may not return.
76 * bidi.c: Integer overflow fix.
77 (bidi_shelve_header_size): New constant.
78 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
79 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
81 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
83 Use ptrdiff_t for composition IDs.
84 * character.c (lisp_string_width):
85 * composite.c (composition_table_size, n_compositions)
86 (get_composition_id, composition_gstring_from_id):
87 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):
88 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING):
89 * window.c (Frecenter):
90 Use ptrdiff_t, not int, for composition IDs.
91 * composite.c (get_composition_id): Check for integer overflow.
92 * composite.h: Adjust prototypes to match the above changes.
94 Use ptrdiff_t for hash table indexes.
95 * category.c (hash_get_category_set):
97 * charset.h (struct charset.hash_index, CHECK_CHARSET_GET_ID):
98 * coding.c (coding_system_charset_list, detect_coding_system):
99 * coding.h (struct coding_system.id):
100 * composite.c (get_composition_id, gstring_lookup_cache):
101 * fns.c (hash_lookup, hash_put, Fgethash, Fputhash):
102 * image.c (xpm_get_color_table_h):
103 * lisp.h (hash_lookup, hash_put):
104 * minibuf.c (Ftest_completion):
105 Use ptrdiff_t for hash table indexes, not int (which is too
106 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
107 32-bit --with-wide-int hosts).
109 * charset.c (Fdefine_charset_internal): Check for integer overflow.
110 Add a FIXME comment about memory leaks.
111 (syms_of_charset): Don't assume xmalloc returns.
113 Don't assume that stated character widths fit in int.
114 * character.c (Fchar_width, c_string_width, lisp_string_width):
115 * character.h (CHAR_WIDTH):
116 * indent.c (MULTIBYTE_BYTES_WIDTH):
117 Use sanitize_char_width to avoid undefined and/or bad behavior
118 with outlandish widths.
119 * character.h (sanitize_tab_width): Renamed from sanitize_width,
120 now that we have two such functions. All uses changed.
121 (sanitize_char_width): New inline function.
123 Don't assume that tab-width fits in int.
124 * character.h (sanitize_width): New inline function.
125 (SANE_TAB_WIDTH): New macro.
126 (ASCII_CHAR_WIDTH): Use it.
127 * indent.c (sane_tab_width): Remove. All uses replaced by
128 SANE_TAB_WIDTH (current_buffer).
129 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
131 * fileio.c: Integer overflow issues with file modes.
132 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
134 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
135 Remove unreachable code.
136 (read_hex, load_charset_map_from_file): Check for integer overflow.
138 * xterm.c: don't go over XClientMessageEvent limit
139 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
140 (x_send_scroll_bar_event): Likewise. Check that the size does not
141 exceed limits imposed by XClientMessageEvent, as well as the usual
142 ptrdiff_t and size_t limits.
144 * keyboard.c: Overflow, signedness and related fixes.
145 (make_lispy_movement): Use same integer type in forward decl
146 that is used in the definition.
147 (read_key_sequence, keyremap_step):
148 Change bufsize argument back to int, undoing my 2011-03-30 change.
149 We prefer signed types, and int is wide enough here.
150 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
151 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
152 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
153 length, not size_t. Use ptrdiff_t for index, not int.
154 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
155 possibility of integer overflow.
157 Overflow, signedness and related fixes for images.
159 * dispextern.h (struct it.stack[0].u.image.image_id)
160 (struct_it.image_id, struct image.id, struct image_cache.size)
161 (struct image_cache.used, struct image_cache.ref_count):
162 * gtkutil.c (update_frame_tool_bar):
163 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
164 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
165 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
166 * nsmenu.m (update_frame_tool_bar):
167 * xdisp.c (calc_pixel_width_or_height):
168 * xfns.c (image_cache_refcount):
169 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
170 on typical 64-bit hosts.
172 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
173 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
174 Omit unnecessary casts to int.
175 (parse_image_spec): Check that integers fall into 'int' range
176 when the callers expect that.
177 (image_ascent): Redo ascent calculation to avoid int overflow.
178 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
179 (lookup_image): Remove unnecessary tests.
180 (xbm_image_p): Locals are now of int, not EMACS_INT,
181 since parse_image_check makes sure they fit into int.
182 (png_load, gif_load, svg_load_image):
183 Prefer int to unsigned where either will do.
184 (tiff_handler): New function, combining the cores of the
185 old tiff_error_handler and tiff_warning_handler. This
186 function is rewritten to use vsnprintf and thereby avoid
187 stack buffer overflows. It uses only the features of vsnprintf
188 that are common to both POSIX and native Microsoft.
189 (tiff_error_handler, tiff_warning_handler): Use it.
190 (tiff_load, gif_load, imagemagick_load_image):
191 Don't assume :index value fits in 'int'.
192 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
193 (imagemagick_load_image): Check that crop parameters fit into
194 the integer types that MagickCropImage accepts. Don't assume
195 Vimagemagick_render_type has a nonnegative value. Don't assume
196 size_t fits in 'long'.
197 (gs_load): Use printmax_t to print the widest integers possible.
198 Check for integer overflow when computing image height and width.
200 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
202 Integer signedness and overflow and related fixes. (Bug#9079)
204 * bidi.c: Integer size and overflow fixes.
205 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
206 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
207 (bidi_cache_find_level_change, bidi_cache_ensure_space)
208 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
209 (bidi_find_other_level_edge):
210 Use ptrdiff_t instead of EMACS_INT where either will do.
211 This works better on 32-bit hosts configured --with-wide-int.
212 (bidi_cache_ensure_space): Check for size-calculation overflow.
213 Use % rather than repeated addition, for better worst-case speed.
214 Don't set bidi_cache_size until after xrealloc returns, because it
216 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
217 (bidi_cache_ensure_space): Also check that the bidi cache size
218 does not exceed that of the largest Lisp string or buffer. See Eli
219 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
221 * alloc.c (__malloc_size_t): Remove.
222 All uses replaced by size_t. See Andreas Schwab's note
223 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
225 * image.c: Improve checking for integer overflow.
226 (check_image_size): Assume that f is nonnull, since
227 it is always nonnull in practice. This is one less thing to
228 worry about when checking for integer overflow later.
229 (x_check_image_size): New function, which checks for integer
230 overflow issues inside X.
231 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
232 This removes the need for a memory_full check.
233 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
234 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
235 (xbm_read_bitmap_data): Change locals back to 'int', since
236 their values must fit in 'int'.
237 (xpm_load_image, png_load, tiff_load):
238 Invoke x_create_x_image_and_pixmap earlier,
239 to avoid much needless work if the image is too large.
240 (tiff_load): Treat overly large images as if
241 x_create_x_image_and_pixmap failed, not as malloc failures.
242 (gs_load): Use x_check_image_size.
244 * gtkutil.c: Omit integer casts.
245 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
246 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
248 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
250 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
251 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
252 would wrongly return t on a 64-bit host.
254 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
255 The plain *_OVERFLOW macros run afoul of GCC bug 49705
256 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
257 and therefore cause GCC to emit a bogus diagnostic in some cases.
259 * image.c: Integer signedness and overflow and related fixes.
260 This is not an exhaustive set of fixes, but it's time to
261 record what I've got.
262 (lookup_pixel_color, check_image_size): Remove redundant decls.
263 (check_image_size): Don't assume that arbitrary EMACS_INT values
264 fit in 'int', or that arbitrary 'double' values fit in 'int'.
265 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
266 (tiff_load, imagemagick_load_image):
267 Check for overflow in size calculations.
268 (x_create_x_image_and_pixmap): Remove unnecessary test for
269 xmalloc returning NULL; that can't happen.
270 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
271 (xpm_color_bucket): Use better integer hashing function.
272 (xpm_cache_color): Don't possibly over-allocate memory.
273 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
275 Use ptrdiff_t, not int or size_t, to record sizes.
276 (png_load): Don't assume values greater than 2**31 fit in 'int'.
277 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
278 either works, as we prefer signed integers.
279 (tiff_read_from_memory, tiff_write_from_memory):
280 Return tsize_t, not size_t, since that's what the TIFF API wants.
281 (tiff_read_from_memory): Don't fail simply because the read would
282 go past EOF; instead, return a short read.
283 (tiff_load): Omit no-longer-needed casts.
284 (Fimagemagick_types): Don't assume size fits into 'int'.
286 Improve hashing quality when configured --with-wide-int.
287 * fns.c (hash_string): New function, taken from sxhash_string.
288 Do not discard information about ASCII character case; this
289 discarding is no longer needed.
290 (sxhash-string): Use it. Change sig to match it. Caller changed.
291 * lisp.h: Declare it.
292 * lread.c (hash_string): Remove, since we now use fns.c's version.
293 The fns.c version returns a wider integer if --with-wide-int is
294 specified, so this should help the quality of the hashing a bit.
296 * emacs.c: Integer overflow minor fix.
297 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
298 Define only if GNU_LINUX.
299 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
301 * dispnew.c: Integer signedness and overflow fixes.
302 Remove unnecessary forward decls, that were a maintenance hassle.
303 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
305 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
306 (scrolling_window): Use ptrdiff_t, not int, for byte count.
307 (prepare_desired_row, line_draw_cost):
308 Use int, not unsigned, where either works.
309 (save_current_matrix, restore_current_matrix):
310 Use ptrdiff_t, not size_t, where either works.
311 (init_display): Check for overflow more accurately, and without
312 relying on undefined behavior.
314 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
315 Remove, replacing with the new symbols in lisp.h. All uses changed.
316 * fileio.c (make_temp_name):
317 * filelock.c (lock_file_1, lock_file):
318 * xdisp.c (message_dolog):
319 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
320 Use pMd etc. instead.
321 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
322 replacing the pWIDE etc. symbols removed from editfns.c.
324 * keyboard.h (num_input_events): Now uintmax_t.
325 This is (very slightly) less likely to mess up due to wraparound.
328 * buffer.c: Integer signedness fixes.
329 (alloc_buffer_text, enlarge_buffer_text):
330 Use ptrdiff_t rather than size_t when either will do, as we prefer
333 * alloc.c: Integer signedness and overflow fixes.
334 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
335 (__malloc_size_t): Default to size_t, not to int.
336 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
337 (Fgarbage_collect, mark_object_loop_halt, mark_object):
338 Prefer ptrdiff_t to size_t when either would do, as we prefer
340 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
341 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
342 Now const. Initialize with values that are in range even if char
344 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
345 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
346 These functions do the right thing with sizes > 2**32.
347 (check_depth): Now ptrdiff_t, not int.
348 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
349 Adjust to new way of storing sizes. Check for size overflow bugs
351 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
352 slightly wrong anyway, as it missed one instance of
353 XMALLOC_OVERRUN_CHECK_OVERHEAD.
354 (refill_memory_reserve): Omit needless cast to size_t.
355 (mark_object_loop_halt): Mark as externally visible.
357 * xselect.c: Integer signedness and overflow fixes.
358 (Fx_register_dnd_atom, x_handle_dnd_message):
359 Use ptrdiff_t, not size_t, since we prefer signed.
360 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
361 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
362 x_dnd_atoms_size and x_dnd_atoms_length.
364 * doprnt.c: Prefer signed to unsigned when either works.
368 * xdisp.c (vmessage):
369 Use ptrdiff_t, not size_t, when using or implementing doprnt,
370 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
371 prefer signed arithmetic to avoid comparison confusion.
372 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
375 Assume freestanding C89 headers, string.h, stdlib.h.
376 * data.c, doprnt.c, floatfns.c, print.c:
377 Include float.h unconditionally.
378 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
379 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
380 * regex.c: Likewise for stddef.h, string.h.
381 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
382 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
383 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
384 (STDC_HEADERS): Remove obsolete defines.
385 * sysdep.c: Include limits.h unconditionally.
387 Assume support for memcmp, memcpy, memmove, memset.
388 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
389 * regex.c (memcmp, memcpy):
390 Remove; we assume C89 now.
392 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
393 (__malloc_safe_bcopy): Remove; no longer needed.
395 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
396 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
397 well either way, and we prefer signed to unsigned.
399 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
402 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
403 and the surrounding thread.
404 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
405 rather than fgets, and retry after EINTR. Otherwise, 'emacs
406 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
408 * s/openbsd.h (BROKEN_SIGIO): Define.
409 * unexelf.c (unexec) [__OpenBSD__]:
410 Don't update the .mdebug section of the Alpha COFF symbol table.
412 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
414 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
417 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
419 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
420 This fixes some race conditions on the permissions of any newly
423 * alloc.c (valid_pointer_p): Use pipe, not open.
424 This fixes some permissions issues when debugging.
426 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
427 If fchown fails to set both uid and gid, try to set just gid,
428 as that is sometimes allowed. Adjust the file's mode to eliminate
429 setuid or setgid bits that are inappropriate if fchown fails.
431 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
433 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
434 to compare Lisp_Objects.
435 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
436 global_gnutls_log_level, don't mistake it for a Lisp_Object.
437 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
439 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
441 * lread.c (read_integer): Unread even EOF character.
442 (read1): Likewise. Properly record start position of symbol.
444 * lread.c (read1): Read `#:' as empty uninterned symbol if no
445 symbol character follows.
447 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
449 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
450 This works around a problem with the previous change to Fcopy_file.
451 Recent glibc declares fchown with __attribute__((warn_unused_result)),
452 and without this change, GCC might complain about discarding
453 fchown's return value.
455 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
457 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).

965 * composite.c (composition_compute_stop_pos): Ignore a static

1027 (clone_per_buffer_values): Don't assume that

1066 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
1068 Random fixes. E.g., (random) never returned negative values.
1069 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
1070 subseconds part to the entropy, as that's a bit more random.
1071 Prefer signed to unsigned, since the signedness doesn't matter and
1072 in general we prefer signed. When given a limit, use a
1073 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
1074 latter isn't right if USE_2_TAGS_FOR_INTS.
1075 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
1076 not 0..VALMASK. Don't discard "excess" bits that random () returns.

1088 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
1089 This is more efficient than Ffile_directory_p and avoids a minor race.
1091 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
1093 * buffer.c (Foverlay_put): Say what the return value is
1096 * fileio.c (barf_or_query_if_file_exists): Check first if the file
1097 is a directory before asking whether to use the file name
1099 (barf_or_query_if_file_exists): Make the "File is a directory"
1100 error be more correct.
1102 * fns.c (Frequire): Remove the mention of the .gz files, since
1103 that's installation-specific, but keep the mention of
1104 `get-load-suffixes'.
1106 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
1108 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

1119 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
1120 Also (re)move comments that are misplaced or no longer relevant.

1183 (syms_of_keymap): Defsubr make-composed-keymap.
1184 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

1219 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
1221 * eval.c (struct backtrace): Simplify and port the data structure.
1222 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
1223 signed bit field, as this assumption is not portable and it makes
1224 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
1225 "char debug_on_exit : 1" as this is not portable either; instead,
1226 use the portable "unsigned int debug_on_exit : 1". Remove unused
1227 member evalargs. Remove obsolete comments about cc bombing out.
1229 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

1391 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
1393 Integer and buffer overflow fixes (Bug#8873).
1395 * print.c (printchar, strout): Check for string overflow.
1396 (PRINTPREPARE, printchar, strout):
1397 Don't set size unless allocation succeeds.

1405 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
1406 Use ptrdiff_t, not int, for sizes.
1407 Don't increment bufsize until after realloc succeeds.
1408 Check for size-calculation overflow.
1409 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
1411 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
1413 * lread.c: Integer overflow fixes.
1414 (read_integer): Radix is now EMACS_INT, not int,
1415 to improve quality of diagnostics for out-of-range radices.
1416 Calculate buffer size correctly for out-of-range radices.
1417 (read1): Check for integer overflow in radices, and in
1418 read-circle numbers.
1419 (read_escape): Avoid int overflow.
1420 (Fload, openp, read_buffer_size, read1)
1421 (substitute_object_recurse, read_vector, read_list, map_obarray):
1422 Use ptrdiff_t, not int, for sizes.
1423 (read1): Use EMACS_INT, not int, for sizes.
1424 Check for size overflow.
1426 * image.c (cache_image): Check for size arithmetic overflow.
1428 * lread.c: Integer overflow issues.
1429 (saved_doc_string_size, saved_doc_string_length)
1430 (prev_saved_doc_string_size, prev_saved_doc_string_length):
1431 Now ptrdiff_t, not int.
1432 (read1): Don't assume doc string length fits in int. Check for
1433 out-of-range doc string lengths.
1434 (read_list): Don't assume file position fits in int.
1435 (read_escape): Check for hex character overflow.
1437 2011-06-22 Leo Liu <sdl.web@gmail.com>
1439 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
1440 Move to minibuffer.el.
1442 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1444 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
1445 The following patches are for when GLYPH_DEBUG && !XASSERT.
1446 * dispextern.h (trace_redisplay_p, dump_glyph_string):
1447 * dispnew.c (flush_stdout):
1448 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
1449 Mark as externally visible.
1450 * dispnew.c (check_window_matrix_pointers): Now static.
1451 * dispnew.c (window_to_frame_vpos):
1452 * xfns.c (unwind_create_frame):
1453 * xterm.c (x_check_font): Remove unused local.
1454 * scroll.c (CHECK_BOUNDS):
1455 * xfaces.c (cache_fache): Rename local to avoid shadowing.
1456 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
1457 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
1458 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
1459 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
1461 (debug_method_add): Use va_list and vsprintf rather than relying
1462 on undefined behavior with wrong number of arguments.
1463 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
1464 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
1465 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
1466 since we're not interested in debugging glyphs with old libraries.
1467 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
1468 GCC 4.6.0's static checking.
1470 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
1472 Integer overflow and signedness fixes (Bug#8873).
1473 A few related buffer overrun fixes, too.

1477 * dispextern.h (struct face.stipple):
1478 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
1479 (x_bitmap_mask, x_allocate_bitmap_record)
1480 (x_create_bitmap_from_data, x_create_bitmap_from_file)
1481 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
1482 (x_create_bitmap_from_xpm_data):
1483 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
1484 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
1486 * xfaces.c (load_pixmap):
1487 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
1488 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
1489 (.bitmaps_last, struct x_output.icon_bitmap):
1490 Use ptrdiff_t, not int, for bitmap indexes.
1491 (x_allocate_bitmap_record): Check for size overflow.
1492 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
1494 Use ptrdiff_t, not int, for overlay counts.
1495 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
1496 * editfns.c (overlays_around, get_pos_property):
1497 * textprop.c (get_char_property_and_overlay):
1498 * xdisp.c (next_overlay_change, note_mouse_highlight):
1499 * xfaces.c (face_at_buffer_position):
1500 * buffer.c (OVERLAY_COUNT_MAX): New macro.
1501 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
1502 (Fnext_overlay_change, Fprevious_overlay_change)
1503 (mouse_face_overlay_overlaps, Foverlays_in):
1504 Use ptrdiff_t, not int, for sizes.
1505 (overlays_at, overlays_in): Check for size-calculation overflow.
1507 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1509 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1510 (x_session_initialize): Do not assume string length fits in int.
1512 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1513 This is unlikely, but can occur if DPI is outlandish.
1515 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1516 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1518 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1519 * xrdb.c (magic_file_p, search_magic_path):
1520 Omit last arg SUFFIX; it was always 0. All callers changed.
1521 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1523 * xfont.c (xfont_match): Avoid need for strlen.
1525 * xfns.c: Don't assume strlen fits in int.
1526 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1528 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1529 not unsigned long, as we prefer signed integers. All callers changed.
1530 Detect integer overflow in repeat count.
1531 (message_dolog): Don't assume print length fits in 39 bytes.
1532 (display_mode_element): Don't assume strlen fits in int.
1534 * termcap.c: Don't assume sizes fit in int and never overflow.
1535 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1536 (gobble_line): Check for size-calculation overflow.
1538 * minibuf.c (Fread_buffer):
1539 * lread.c (intern, intern_c_string):
1540 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1541 Don't assume string length fits in int.
1543 * keyboard.c (parse_tool_bar_item):
1544 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1546 * font.c: Don't assume string length fits in int.
1547 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1548 Use ptrdiff_t, not int.
1549 (font_intern_prop): Don't assume string length fits in int.
1550 Don't assume integer property fits in fixnum.
1551 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1553 * filelock.c: Fix some buffer overrun and integer overflow issues.
1554 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1555 Reformulate so as not to need the command string.
1556 Invoke gzip -cd rather than gunzip, as it's more portable.
1557 (lock_info_type, lock_file_1, lock_file):
1558 Don't assume pid_t and time_t fit in unsigned long.
1559 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1560 (current_lock_owner): Prefer signed type for sizes.
1561 Use memcpy, not strncpy, where memcpy is what is really wanted.
1562 Don't assume (via atoi) that time_t and pid_t fit in int.
1563 Check for time_t and/or pid_t out of range, e.g., via a network share.
1564 Don't alloca where an auto var works fine.
1566 * fileio.c: Fix some integer overflow issues.
1567 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1568 Don't assume string length fits in int.
1569 (directory_file_name): Don't assume string length fits in long.
1570 (make_temp_name): Don't assume pid fits in int, or that its print
1571 length is less than 20.
1573 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1575 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1577 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1579 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1580 We prefer signed integers, even for size calculations.
1582 * emacs.c: Don't assume string length fits in 'int'.
1583 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1584 (main): Don't invoke strlen when not needed.
1586 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1587 (XD_DEBUG_MESSAGE): Don't waste a byte.
1589 * callproc.c (getenv_internal_1, getenv_internal)
1591 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1593 * lread.c (invalid_syntax): Omit length argument.
1594 All uses changed. This doesn't fix a bug, but it simplifies the
1595 code away from its former Hollerith-constant appearance, and it's
1596 one less 'int' to worry about when looking at integer-overflow issues.
1597 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1599 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1600 This didn't break anything, but it didn't help either.
1601 It's confusing to put a bogus integer in a place where the actual
1602 value does not matter.
1603 (LIST_END_P): Remove unused macro and its bogus comment.
1604 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1606 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1607 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1609 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1610 We prefer signed types, and the value cannot exceed the EMACS_INT
1611 range anyway (because otherwise the length would not be representable).
1612 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1613 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1614 This avoids a GCC warning when WIDE_EMACS_INT.
1616 * indent.c (sane_tab_width): New function.
1617 (current_column, scan_for_column, Findent_to, position_indentation)
1618 (compute_motion): Use it. This is just for clarity.
1619 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1621 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1623 * lisp.h (lint_assume): New macro.
1624 * composite.c (composition_gstring_put_cache):
1625 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1627 * editfns.c, insdel.c:
1628 Omit unnecessary forward decls, to simplify future changes.
1630 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1632 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1634 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1635 Use much-faster test for byte-length change.
1636 Don't assume string byte-length fits in 'int'.
1637 Check that character arg fits in 'int'.
1638 (mapcar1): Declare byte as byte, for clarity.
1640 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1642 * fns.c (concat): Catch string overflow earlier.
1643 Do not rely on integer wraparound.
1645 * dispextern.h (struct it.overlay_strings_charpos)
1646 (struct it.selective): Now EMACS_INT, not int.
1647 * xdisp.c (forward_to_next_line_start)
1648 (back_to_previous_visible_line_start)
1649 (reseat_at_next_visible_line_start, next_element_from_buffer):
1650 Don't arbitrarily truncate the value of 'selective' to int.
1652 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1654 * composite.c: Don't truncate sizes to 'int'.
1655 (composition_gstring_p, composition_reseat_it)
1656 (composition_adjust_point): Use EMACS_INT, not int.
1657 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1658 not EMACS_UINT, for indexes.
1660 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1662 * buffer.c: Include <verify.h>.
1663 (struct sortvec.priority, struct sortstr.priority):
1664 Now EMACS_INT, not int.
1665 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1666 (struct sortstr.size, record_overlay_string)
1667 (struct sortstrlist.size, struct sortlist.used):
1668 Don't truncate size to int.
1669 (record_overlay_string): Check for size-calculation overflow.
1670 (init_buffer_once): Check at compile-time, not run-time.
1672 2011-06-22 Jim Meyering <meyering@redhat.com>
1674 Don't leak an XBM-image-sized buffer
1675 * image.c (xbm_load): Free the image buffer after using it.
1677 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1680 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1681 that Sun C diagnosed.
1682 * fns.c (secure_hash): Fix pointer signedness issue.
1683 * intervals.c (static_offset_intervals): New function.
1684 (offset_intervals): Use it.
1686 2011-06-21 Leo Liu <sdl.web@gmail.com>
1689 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1692 * fns.c (secure_hash): Rename from crypto_hash_function and change
1693 the first arg to accept symbols.
1694 (Fsecure_hash): New primitive.
1695 (syms_of_fns): New symbols.
1697 2011-06-20 Deniz Dogan <deniz@dogan.se>
1699 * process.c (Fset_process_buffer): Clarify return value in
1702 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1704 * dispnew.c (add_window_display_history): Use BVAR.
1706 * xdisp.c (debug_method_add): Use BVAR.
1707 (check_window_end, dump_glyph_matrix, dump_glyph)
1708 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1710 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1713 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1714 check till after the cache is created in init_frame_faces.
1716 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1718 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1720 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1722 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1723 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1724 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1726 Improve buffer-overflow checking (Bug#8873).
1727 * fileio.c (Finsert_file_contents):
1728 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1729 Remove the old (too-loose) buffer overflow checks.
1730 They weren't needed, since make_gap checks for buffer overflow.
1731 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1732 The old code merely checked for Emacs fixnum overflow, and relied
1733 on undefined (wraparound) behavior. The new code avoids undefined
1734 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1736 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1737 Tune. Don't use wider integers than needed. Don't use alloca.
1738 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1740 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1742 * insdel.c, lisp.h (buffer_overflow): New function.
1743 (insert_from_buffer_1, replace_range, replace_range_2):
1744 * insdel.c (make_gap_larger):
1745 * editfns.c (Finsert_char):
1746 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1748 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1750 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1752 Integer overflow and signedness fixes (Bug#8873).
1754 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1755 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1757 * fileio.c: Don't assume EMACS_INT fits in off_t.
1758 (emacs_lseek): New static function.
1759 (Finsert_file_contents, Fwrite_region): Use it.
1760 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1762 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1764 * fns.c: Don't overflow int when computing a list length.
1765 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1766 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1767 truncation on 64-bit hosts. Check for QUIT every
1768 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1769 faster and is responsive enough.
1770 (Flength): Report an error instead of overflowing an integer.
1771 (Fsafe_length): Return a float if the value is not representable
1772 as a fixnum. This shouldn't happen except in contrived situations.
1773 (Fnthcdr, Fsort): Don't assume list length fits in int.
1774 (Fcopy_sequence): Don't assume vector length fits in int.
1776 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1777 (header_size, word_size): New constants.
1778 (allocate_vectorlike): Don't check size overflow here.
1779 (allocate_vector): Check it here instead, since this is the only
1780 caller of allocate_vectorlike that could cause overflow.
1781 Check that the new vector's length is representable as a fixnum.
1783 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1784 The previous code was bogus. For example, next_almost_prime (32)
1785 returned 39, which is undesirable as it is a multiple of 3; and
1786 next_almost_prime (24) returned 25, which is a multiple of 5 so
1787 why was the code bothering to check for multiples of 7?
1789 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1791 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1793 Variadic C functions now count arguments with ptrdiff_t.
1794 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1795 Back then I didn't know that the Emacs coding style prefers signed int.
1796 Also, in the meantime I found a few more instances where arguments
1797 were being counted with int, which may truncate counts on 64-bit
1798 machines, or EMACS_INT, which may be unnecessarily wide.
1799 * lisp.h (struct Lisp_Subr.function.aMANY)
1800 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1801 Arg counts are now ptrdiff_t, not size_t.
1802 All variadic functions and their callers changed accordingly.
1803 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1804 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1805 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1806 * callint.c (Fcall_interactively): Check arg count for overflow,
1807 to avoid potential buffer overrun. Use signed char, not 'int',
1808 for 'varies' array, so that we needn't bother to check its size
1809 calculation for overflow.
1810 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1811 * eval.c (apply_lambda):
1812 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1813 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1814 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1816 * callint.c (Fcall_interactively): Don't use index var as event count.
1818 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1819 * mem-limits.h (SIZE): Remove; no longer used.
1821 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1823 Remove unnecessary casts.
1824 * xterm.c (x_term_init):
1825 * xfns.c (x_set_border_pixel):
1826 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1827 These aren't needed now that we assume ANSI C.
1829 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1830 It's more likely to cause problems (due to unsigned overflow)
1833 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1835 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1837 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1839 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1841 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1843 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1845 GLYPH_CODE_FACE returns EMACS_INT, not int.
1846 * dispextern.h (merge_faces):
1847 * xfaces.c (merge_faces):
1848 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1849 Don't assume EMACS_INT fits in int.
1851 * character.h (CHAR_VALID_P): Remove unused parameter.
1852 * fontset.c, lisp.h, xdisp.c: All uses changed.
1854 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1856 * fns.c (concat): Minor tuning based on overflow analysis.
1857 This doesn't fix any bugs. Use int to hold character, instead
1858 of constantly refetching from Emacs object. Use XFASTINT, not
1859 XINT, for value known to be a character. Don't bother comparing
1860 a single byte to 0400, as it's always less.
1862 * floatfns.c (Fexpt):
1863 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1865 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1868 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1870 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1871 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1872 incorrectly succeed when S was a string, because 4294967386 was
1873 truncated before it was used.
1875 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1876 Otherwise, an out-of-range integer could cause undefined behavior
1879 * composite.c: Use int, not EMACS_INT, for characters.
1880 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1881 EMACS_INT, for values that are known to be in character range.
1882 This doesn't fix any bugs but is the usual style inside Emacs and
1883 may generate better code on 32-bit machines.
1885 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1886 This is for reasons similar to the recent CHAR_STRING fix.
1887 * charset.c (Fencode_char): Check that character arg is actually
1888 a character. Pass an int to ENCODE_CHAR.
1889 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1890 wider than 'int', as a compile-time check to prevent future regressions
1893 * character.c (char_string): Remove unnecessary casts.
1895 Make sure a 64-bit char is never passed to CHAR_STRING.
1896 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1897 by silently ignoring the top 32 bits, allowing some values
1898 that were far too large to be valid characters.
1899 * character.h: Include <verify.h>.
1900 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1901 arguments are no wider than unsigned, as a compile-time check
1902 to prevent future regressions in this area.
1904 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1905 (Fsubst_char_in_region):
1907 * xdisp.c (decode_mode_spec_coding):
1908 Adjust to CHAR_STRING's new requirement.
1909 * editfns.c (Finsert_char, Fsubst_char_in_region):
1910 * fns.c (concat): Check that character args are actually
1911 characters. Without this test, these functions did the wrong
1912 thing with wildly out-of-range values on 64-bit hosts.
1914 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
1915 These casts should not be needed on 32-bit hosts, either.
1916 * keyboard.c (read_char):
1917 * lread.c (Fload): Remove casts to unsigned.
1919 * lisp.h (UNSIGNED_CMP): New macro.
1920 This fixes comparison bugs on 64-bit hosts.
1921 (ASCII_CHAR_P): Use it.
1922 * casefiddle.c (casify_object):
1923 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
1924 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
1925 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
1926 * dispextern.h (FACE_FROM_ID):
1927 * keyboard.c (read_char): Use UNSIGNED_CMP.
1929 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
1930 not to EMACS_INT, to avoid GCC warning.
1932 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
1934 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
1935 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
1936 isn't needed on 32-bit machines.
1938 * buffer.c (Fgenerate_new_buffer_name):
1939 Use EMACS_INT for count, not int.
1940 (advance_to_char_boundary): Return EMACS_INT, not int.
1942 * data.c (Qcompiled_function): Now static.
1944 * window.c (window_body_lines): Now static.
1946 * image.c (gif_load): Rename local to avoid shadowing.
1948 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
1949 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
1950 * alloc.c (make_save_value): Integer argument is now of type
1952 (mark_object): Use ptrdiff_t, not int.
1953 * lisp.h (pD): New macro.
1954 * print.c (print_object): Use it.
1956 * alloc.c: Use EMACS_INT, not int, to count objects.
1957 (total_conses, total_markers, total_symbols, total_vector_size)
1958 (total_free_conses, total_free_markers, total_free_symbols)
1959 (total_free_floats, total_floats, total_free_intervals)
1960 (total_intervals, total_strings, total_free_strings):
1961 Now EMACS_INT, not int. All uses changed.
1962 (Fgarbage_collect): Compute overall total using a double, so that
1963 integer overflow is less likely to be a problem. Check for overflow
1964 when converting back to an integer.
1965 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
1966 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
1967 These were 'int' variables that could overflow on 64-bit hosts;
1968 they were never used, so remove them instead of repairing them.
1969 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
1970 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
1971 Previously, this ceilinged at INT_MAX, but that doesn't work on
1973 (allocate_pseudovector): Don't use EMACS_INT when int would do.
1975 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
1976 (allocate_vectorlike): Check for ptrdiff_t overflow.
1977 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
1978 when a (possibly-narrower) signed value would do just as well.
1979 We prefer using signed arithmetic, to avoid comparison confusion.
1981 * alloc.c: Catch some string size overflows that we were missing.
1982 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
1983 for convenience in STRING_BYTES_MAX.
1984 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
1985 The definition here is exact; the one in lisp.h was approximate.
1986 (allocate_string_data): Check for string overflow. This catches
1987 some instances we weren't catching before. Also, it catches
1988 size_t overflow on (unusual) hosts where SIZE_MAX <= min
1989 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
1990 and ptrdiff_t and EMACS_INT are both 64 bits.
1992 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
1993 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
1994 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
1996 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
1998 * alloc.c (Fmake_string): Check for out-of-range init.
2000 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
2002 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

2015 Call gtk_window_set_resizable if HAVE_GTK3.
2016 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
2017 and height if HAVE_GTK3 (Bug#8505).

2019 (update_theme_scrollbar_width): New function.
2020 (xg_get_default_scrollbar_width): Move code to
2021 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

2024 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
2026 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

2580 bidi_it->nchars is non-positive.
2581 (bidi_level_of_next_char): Don't try to lookup the cache for the

2600 (compute_display_string_pos): Accept additional argument
2601 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2602 value of a `display' property is a "replacing spec".
2603 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2604 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

2634 * gnutls.c: Use Emacs's memory allocators.
2635 Without this change, the gnutls library would invoke malloc etc.
2636 directly, which causes problems on non-SYNC_INPUT hosts, and which
2637 runs afoul of improving memory_full behavior. (Bug#8761)
2638 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2639 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2640 xfree instead of the default malloc, realloc, free.
2641 (Fgnutls_boot): No need to check for memory allocation failure,
2642 since xmalloc does that for us.

2667 Check for overflow in vector size calculations.
2668 * ccl.c (ccl_driver):
2669 Check for overflow when converting EMACS_INT to int.
2670 * fns.c, image.c: Remove unnecessary static decls that would otherwise
2671 need to be updated by these changes.

2673 Check for integer overflow with large hash tables.
2674 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2675 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2676 (SXHASH_REDUCE): New macro.
2677 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2678 Use it instead of discarding useful hash info with large hash values.
2679 (sxhash_float): New function.
2680 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2681 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2682 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2683 Rewrite to use FIXNUM_BITS, as this simplifies things.
2684 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2685 Adjust signatures to match updated version of code.
2686 (consing_since_gc): Now EMACS_INT, since a single hash table can
2687 use more than INT_MAX bytes.

2736 Make it possible to run ./temacs.
2738 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2739 syms_of_callproc does the same thing. Remove test for
2740 "initialized", do it in the caller.
2741 * emacs.c (main): Avoid calling set_initial_environment when dumping.

2769 (Fimagemagick_types): Doc fix.
2771 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
2773 Minor fixes prompted by GCC 4.6.0 warnings.
2775 * xselect.c (converted_selections, conversion_fail_tag): Now static.
2777 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
2778 (x_clipboard_manager_save_all): Move extern decl to ...
2779 * xterm.h: ... here, so that it can be checked for consistency.
2781 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
2783 * xselect.c (x_clipboard_manager_save_frame)
2784 (x_clipboard_manager_save_all): New functions.
2785 (Fx_clipboard_manager_save): Lisp function deleted.
2787 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
2788 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
2790 * xterm.h: Update prototype.
2792 2011-05-28 William Xu <william.xwl@gmail.com>
2794 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
2797 2011-05-28 Jim Meyering <meyering@redhat.com>
2799 Avoid a sign-extension bug in crypto_hash_function.
2800 * fns.c (to_uchar): Define.
2801 (crypto_hash_function): Use it to convert some newly-signed
2802 variables to unsigned, to avoid sign-extension bugs. For example,
2803 without this change, (md5 "truc") would evaluate to
2804 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2805 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2806 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
2808 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2810 Integer overflow fixes.
2812 * dbusbind.c: Serial number integer overflow fixes.
2813 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
2814 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
2815 to hold a serial number that is too large for a fixnum.
2816 (Fdbus_method_return_internal, Fdbus_method_error_internal):
2817 Check for serial numbers out of range. Decode any serial number
2818 that was so large that it became a float. (Bug#8722)
2820 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
2821 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2822 Use XFASTINT rather than XUINT when numbers are nonnegative.
2823 (xd_append_arg, Fdbus_method_return_internal):
2824 (Fdbus_method_error_internal): Likewise. Also, for unsigned
2825 arguments, check that Lisp number is nonnegative, rather than
2826 silently wrapping negative numbers around. (Bug#8722)
2827 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
2830 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
2832 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
2834 ccl: add integer overflow checks
2835 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
2836 (IN_INT_RANGE): New macros.
2837 (ccl_driver): Use them to check for integer overflow when
2838 decoding a CCL program. Many of the new checks are whether XINT (x)
2839 fits in int; it doesn't always, on 64-bit hosts. The new version
2840 doesn't catch all possible integer overflows, but it's an
2841 improvement. (Bug#8719)
2843 * alloc.c (make_event_array): Use XINT, not XUINT.
2844 There's no need for unsigned here.
2846 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2847 This follows up to the 2011-05-06 change that substituted uintptr_t
2848 for EMACS_INT. This case wasn't caught back then.
2850 Rework Fformat to avoid integer overflow issues.
2851 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2852 now (part of C89). Include <verify.h>.
2853 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2854 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2855 (Fformat): Avoid the prepass trying to compute sizes; it was only
2856 approximate and thus did not catch overflow reliably. Instead, walk
2857 through the format just once, formatting and computing sizes as we go,
2858 checking for integer overflow at every step, and allocating a larger
2859 buffer as needed. Keep track separately whether the format is
2860 multibyte. Keep only the most-recently calculated precision, rather
2861 than them all. Record whether each argument has been converted to
2862 string. Use EMACS_INT, not int, for byte and char and arg counts.
2863 Support field widths and precisions larger than INT_MAX. Avoid
2864 sprintf's undefined behavior with conversion specifications such as %#d
2865 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2866 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2867 formatting out-of-range floating point numbers with int
2870 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2872 * data.c: Avoid integer truncation in expressions involving floats.
2873 * data.c: Include <intprops.h>.
2874 (arith_driver): When there's an integer overflow in an expression
2875 involving floating point, convert the integers to floating point
2876 so that the resulting value does not suffer from catastrophic
2877 integer truncation. For example, on a 64-bit host (* 4
2878 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2879 Do not rely on undefined behavior after integer overflow.
2881 merge count_size_as_multibyte, parse_str_to_multibyte
2882 * character.c, character.h (count_size_as_multibyte):
2883 Rename from parse_str_to_multibyte; all uses changed.
2884 Check for integer overflow.
2885 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2886 since it's now a duplicate of the other. This is more of
2887 a character than a buffer op, so better that it's in character.c.
2888 * fns.c, print.c: Adjust to above changes.
2890 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2892 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2894 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2896 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2897 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2898 (x_clipboard_manager_save): Now static.
2899 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2901 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2902 (crypto_hash_function): Now static.
2903 Fix pointer signedness problems. Avoid unnecessary initializations.
2905 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2907 * termhooks.h (Vselection_alist): Make it terminal-local.
2909 * terminal.c (create_terminal): Initialize it.
2911 * xselect.c: Support for clipboard managers.
2912 (Vselection_alist): Move to termhooks.h as terminal-local var.
2913 (LOCAL_SELECTION): New macro.
2914 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
2915 (symbol_to_x_atom): Remove gratuitous arg.
2916 (x_handle_selection_request, lisp_data_to_selection_data)
2917 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
2918 (x_own_selection, x_get_local_selection, x_convert_selection):
2919 New arg, specifying work frame. Use terminal-local Vselection_alist.
2920 (some_frame_on_display): Delete unused function.
2921 (Fx_own_selection_internal, Fx_get_selection_internal)
2922 (Fx_disown_selection_internal, Fx_selection_owner_p)
2923 (Fx_selection_exists_p): New optional frame arg.
2924 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
2925 (x_handle_selection_clear): Don't treat other terminals with the
2926 same keyboard specially. Use the terminal-local Vselection_alist.
2927 (x_clear_frame_selections): Use Frun_hook_with_args.
2929 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
2931 * xterm.h: Add support for those atoms.
2933 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
2935 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
2936 (converted_selections, conversion_fail_tag): New global variables.
2937 (x_selection_request_lisp_error): Free the above.
2938 (x_get_local_selection): Remove unnecessary code.
2939 (x_reply_selection_request): Args changed; handle arbitrary array
2940 of converted selections stored in converted_selections.
2941 Separate the XChangeProperty and SelectionNotify steps.
2942 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
2943 (x_convert_selection): New function.
2944 (x_handle_selection_event): Simplify.
2945 (x_get_foreign_selection): Don't ignore incoming requests while
2946 waiting for an answer; this will fail when we implement
2947 SAVE_TARGETS, and seems unnecessary anyway.
2948 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
2949 (Vx_sent_selection_functions): Doc fix.
2951 2011-05-26 Leo Liu <sdl.web@gmail.com>
2953 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
2955 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2957 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
2959 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
2960 for fringe update if it has periodic bitmap.
2961 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
2962 and fringe_bitmap_periodic_p.
2964 * fringe.c (get_fringe_bitmap_data): New function.
2965 (draw_fringe_bitmap_1, update_window_fringes): Use it.
2966 (update_window_fringes): Record periodicity of fringe bitmap in glyph
2967 row. Mark glyph row for fringe update if periodicity changed.
2969 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
2970 for fringe update unless it has periodic bitmap.
2972 2011-05-25 Kenichi Handa <handa@m17n.org>
2974 * xdisp.c (get_next_display_element): Set correct it->face_id for
2975 a static composition.
2977 2011-05-24 Leo Liu <sdl.web@gmail.com>
2980 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
2982 * fns.c (crypto_hash_function, Fsha1): New function.
2983 (Fmd5): Use crypto_hash_function.
2984 (syms_of_fns): Add Ssha1.
2986 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2988 * gnutls.c: Remove unused macros.
2989 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
2990 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
2991 Remove macros that are defined and never used.
2992 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
2994 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2996 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
2997 (Fx_get_selection_internal): Minor cleanup.
2998 (Fx_own_selection_internal): Rename arguments for consistency with
3001 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3003 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
3005 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
3007 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
3009 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3011 * dispnew.c (scrolling_window): Don't exclude the case that the
3012 last enabled row in the desired matrix touches the bottom boundary.
3014 2011-05-21 Glenn Morris <rgm@gnu.org>
3016 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
3017 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
3018 and add some more files.
3020 2011-05-20 Eli Zaretskii <eliz@gnu.org>
3022 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
3023 report_file_error introduced by the change from 2011-05-07.
3025 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
3027 * systime.h (Time): Define only if emacs is defined.
3028 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
3029 where the include path doesn't have X11/X.h by default. See
3030 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
3032 2011-05-20 Kenichi Handa <handa@m17n.org>
3034 * composite.c (find_automatic_composition): Fix previous change.
3036 2011-05-20 Glenn Morris <rgm@gnu.org>
3038 * lisp.mk: New file, split from Makefile.in.
3039 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
3040 (shortlisp): Remove.
3041 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
3043 2011-05-19 Glenn Morris <rgm@gnu.org>
3045 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
3046 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
3047 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
3048 (lisp): Set the order to that of loadup.el.
3049 (shortlisp): Make it a copy of $lisp.
3050 (SOME_MACHINE_LISP): Remove.
3051 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
3052 Use just $shortlisp, not $SOME_MACHINE_LISP too.
3054 2011-05-18 Kenichi Handa <handa@m17n.org>
3056 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
3057 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
3058 (find_automatic_composition): Mostly rewrite for efficiency.
3060 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
3062 * makefile.w32-in: Update dependencies.
3064 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
3066 * menu.c: Include limits.h (fixes the MS-Windows build broken by
3067 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
3069 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
3071 Fix some integer overflow issues, such as string length overflow.
3073 * insdel.c (count_size_as_multibyte): Check for string overflow.
3075 * character.c (lisp_string_width): Check for string overflow.
3076 Use EMACS_INT, not int, for string indexes and lengths; in
3077 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
3078 the resulting string length overflows an EMACS_INT; instead,
3079 report a string overflow if no precision given. When checking for
3080 precision exhaustion, use a check that cannot possibly have
3081 integer overflow. (Bug#8675)
3082 * character.h (lisp_string_width): Adjust to new signature.
3084 * alloc.c (string_overflow): New function.
3085 (Fmake_string): Use it. This doesn't change behavior, but saves
3086 a few bytes and will simplify future changes.
3087 * character.c (string_escape_byte8): Likewise.
3088 * lisp.h (string_overflow): New decl.
3090 Fixups, following up to the user-interface timestamp change.
3091 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
3092 for UI timestamps, instead of unsigned long.
3093 * msdos.c (mouse_get_pos): Likewise.
3094 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
3095 * w32gui.h (Time): Define by including "systime.h" rather than by
3096 declaring it ourselves. (Bug#8664)
3098 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
3099 * image.c (clear_image_cache): Likewise.
3101 * term.c (term_mouse_position): Don't assume time_t wraparound.
3103 Be more systematic about user-interface timestamps.
3104 Before, the code sometimes used 'Time', sometimes 'unsigned long',
3105 and sometimes 'EMACS_UINT', to represent these timestamps.
3106 This change causes it to use 'Time' uniformly, as that's what X uses.
3107 This makes the code easier to follow, and makes it easier to catch
3108 integer overflow bugs such as Bug#8664.
3109 * frame.c (Fmouse_position, Fmouse_pixel_position):
3110 Use Time, not unsigned long, for user-interface timestamps.
3111 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
3112 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
3113 * keyboard.h (last_event_timestamp): Likewise.
3114 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
3115 * menu.h (xmenu_show): Likewise.
3116 * term.c (term_mouse_position): Likewise.
3117 * termhooks.h (struct input_event.timestamp): Likewise.
3118 (struct terminal.mouse_position_hook): Likewise.
3119 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
3120 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
3121 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
3122 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
3124 * menu.h, termhooks.h: Include "systime.h", for Time.
3126 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
3127 Don't assume that the difference between two unsigned long values
3128 can fit into an integer. At this point, we know button_down_time
3129 <= event->timestamp, so the difference must be nonnegative, so
3130 there's no need to cast the result if double-click-time is
3131 nonnegative, as it should be; check that it's nonnegative, just in
3132 case. This bug is triggered when events are more than 2**31 ms
3133 apart (about 25 days). (Bug#8664)
3135 * xselect.c (last_event_timestamp): Remove duplicate decl.
3136 (x_own_selection): Remove needless cast to unsigned long.
3138 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
3139 that always fit in int. Use a sentinel instead of a counter, to
3140 avoid a temp and to allay GCC's concerns about possible int overflow.
3141 * frame.h (struct frame): Use int for menu_bar_items_used
3142 instead of EMACS_INT, since it always fits in int.
3144 * menu.c (grow_menu_items): Check for int overflow.
3146 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
3148 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
3149 Before, the code was not consistent. These values cannot exceed
3150 2**31 - 1 so there's no need to make them unsigned.
3151 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
3152 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
3153 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
3155 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
3157 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
3158 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
3159 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
3160 presumably because the widths might not match.
3162 * window.c (size_window): Avoid needless test at loop start.
3164 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
3166 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
3168 2011-05-12 Drew Adams <drew.adams@oracle.com>
3170 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
3172 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3174 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
3175 `width' to `bar_area_x' and `bar_area_width', respectively.
3176 (x_scroll_run): Take account of fringe background extension.
3178 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
3179 Rename local vars `left' and `width' to `bar_area_x' and
3180 `bar_area_width', respectively.
3181 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
3182 background extension.
3184 2011-05-10 Jim Meyering <meyering@redhat.com>
3186 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
3188 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
3190 * image.c (Finit_image_library): Return t for built-in image types,
3191 like pbm and xbm. (Bug#8640)
3193 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
3195 * w32menu.c (set_frame_menubar): Fix submenu allocation.
3197 2011-05-07 Eli Zaretskii <eliz@gnu.org>
3199 * w32console.c (Fset_screen_color): Doc fix.
3200 (Fget_screen_color): New function.
3201 (syms_of_ntterm): Defsubr it.
3203 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
3204 unlink the temporary file if Fcall_process didn't create it in the
3206 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
3207 child process will be redirected to a file specified with `:file'.
3208 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
3209 cue to call_process_cleanup not to close that handle.
3211 2011-05-07 Ben Key <bkey76@gmail.com>
3213 * makefile.w32-in: The bootstrap-temacs rule now makes use of
3214 one of two shell specific rules, either bootstrap-temacs-CMD or
3215 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
3216 to the previous implementation of the bootstrap-temacs rule.
3217 The bootstrap-temacs-CMD rule is similar to the previous
3218 implementation of the bootstrap-temacs rule except that it
3219 makes use of the ESC_CFLAGS variable instead of the CFLAGS
3222 These changes, along with some changes to nt/configure.bat,
3223 nt/gmake.defs, and nt/nmake.defs, are required to extend my
3224 earlier fix to add support for --cflags and --ldflags options
3225 that include quotes so that it works whether make uses cmd or
3228 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
3230 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
3231 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
3233 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
3234 a string. Handle both cases.
3235 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
3236 (Fdbus_register_method): Use Qinvalid_function.
3238 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3240 * makefile.w32-in: Update dependencies.
3241 (LISP_H): Add inttypes.h and stdin.h.
3242 (PROCESS_H): Add unistd.h.
3244 2011-05-06 Eli Zaretskii <eliz@gnu.org>
3246 * lread.c: Include limits.h (fixes the MS-Windows build broken by
3247 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
3249 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
3251 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
3253 * term.c (vfatal): Remove stray call to va_end.
3254 It's not needed and the C Standard doesn't allow it here anyway.
3256 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
3257 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
3259 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
3262 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
3264 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
3266 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
3268 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
3270 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
3272 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
3273 * charset.c (Fdefine_charset_internal): Don't initialize
3274 charset.code_space[15]. The value was garbage, on hosts with
3275 32-bit int (Bug#8600).
3277 * lread.c (read_integer): Be more consistent with string-to-number.
3278 Use string_to_number to do the actual conversion; this avoids
3279 rounding errors and fixes some other screwups. Without this fix,
3280 for example, #x1fffffffffffffff was misread as -2305843009213693952.
3281 (digit_to_number): Move earlier, for benefit of read_integer.
3282 Return -1 if the digit is out of range for the base, -2 if it is
3283 not a digit in any supported base. (Bug#8602)
3285 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
3287 * dispnew.c (scrolling_window): Return 1 if we scrolled,
3288 to match comment at start of function. This also removes a
3289 GCC warning about overflow in a 32+64-bit port.
3291 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
3293 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
3294 Reported by Stefan Monnier in
3295 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
3296 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3297 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
3299 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
3300 (EMACS_UINTPTR): Likewise, with uintptr_t.
3302 * lisp.h: Prefer 64-bit EMACS_INT if available.
3303 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
3304 on 32-bit hosts that have 64-bit int, so that they can access
3306 However, temporarily disable this change unless the temporary
3307 symbol WIDE_EMACS_INT is defined.
3309 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
3311 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
3312 This removes an assumption that EMACS_INT and long are the same
3313 width as pointers. The assumption is true for Emacs porting targets
3314 now, but we want to make other targets possible.
3315 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
3316 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
3317 In the rest of the code, change types of integers that hold casted
3318 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
3319 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
3320 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
3321 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
3322 No need to cast type when ORing.
3323 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
3324 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
3325 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
3326 assume EMACS_INT is the same width as char *.
3327 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
3328 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
3329 Remove no-longer-needed casts.
3330 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
3331 (xg_tool_bar_help_callback, xg_make_tool_item):
3332 Use EMACS_INTPTR to hold an integer
3333 that will be cast to void *; this can avoid a GCC warning
3334 if EMACS_INT is not the same width as void *.
3335 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
3336 * xdisp.c (display_echo_area_1, resize_mini_window_1):
3337 (current_message_1, set_message_1):
3338 Use a local to convert to proper width without a cast.
3339 * xmenu.c (dialog_selection_callback): Likewise.
3341 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
3342 Also, don't assume VALBITS / RAND_BITS is less than 5,
3343 and don't rely on undefined behavior when shifting a 1 left into
3345 * lisp.h (get_random): Change signature to match.
3347 * lread.c (hash_string): Use size_t, not int, for hash computation.
3348 Normally we prefer signed values; but hashing is special, because
3349 it's better to use unsigned division on hash table sizes so that
3350 the remainder is nonnegative. Also, size_t is the natural width
3351 for hashing into memory. The previous code used 'int', which doesn't
3352 retain enough info to hash well into very large tables.
3353 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
3355 * dbusbind.c: Don't possibly lose pointer info when converting.
3356 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
3357 Use XPNTR rather than XHASH, so that the high-order bits of
3358 the pointer aren't lost when converting through void *.
3360 * eval.c (Fautoload): Don't double-shift a pointer.
3362 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
3364 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
3366 * gnutls.c (DEF_GNUTLS_FN):
3367 * image.c (DEF_IMGLIB_FN): Make function pointers static.
3369 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
3371 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
3374 2011-05-05 Eli Zaretskii <eliz@gnu.org>
3376 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
3377 New version that can reserve upto 2GB of heap space.
3379 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
3381 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
3383 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
3385 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
3386 `gnutls_certificate_set_x509_key_file'.
3388 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
3390 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
3391 Update dependencies.
3393 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3395 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
3396 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
3397 Remove unused parameter `fildes'.
3398 * process.c (read_process_output, send_process): Don't pass it.
3400 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3402 Fix previous change: the library cache is defined in w32.c.
3403 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
3404 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
3406 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
3408 Implement dynamic loading of GnuTLS on Windows.
3410 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
3411 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
3412 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3415 * gnutls.c (Qgnutls_dll): Define.
3416 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
3417 (gnutls_*): Declare function pointers.
3418 (init_gnutls_functions): New function to initialize function pointers.
3419 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
3420 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
3421 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
3422 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
3423 (emacs_gnutls_write, emacs_gnutls_read)
3424 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
3425 (Fgnutls_available_p): New function.
3426 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
3427 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
3428 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
3430 * image.c: Include w32.h.
3431 (Vimage_type_cache): Delete.
3432 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
3433 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
3434 (w32_delayed_load): Move to w32.c.
3436 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
3438 * w32.c (QCloaded_from, Vlibrary_cache): Define.
3439 (w32_delayed_load): Move from image.c. When loading a library, record
3440 its filename in the :loaded-from property of the library id.
3441 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
3442 Initialize and staticpro them.
3443 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
3445 * process.c: Include lisp.h before w32.h, not after.
3446 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
3447 instead of gnutls_record_check_pending.
3449 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
3451 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
3453 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
3454 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
3457 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
3459 * xterm.c (x_set_frame_alpha): Do not set property on anything
3460 else than FRAME_X_OUTER_WINDOW (Bug#8608).
3462 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3464 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
3466 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
3468 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
3469 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
3470 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

3475 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
3476 (Qgnutls_bootprop_callbacks_verify): Make static.
3478 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
3480 * callproc.c: Indentation fixup.
3482 * sysdep.c (wait_for_termination_1): Make static.
3483 (wait_for_termination, interruptible_wait_for_termination):
3484 Move after wait_for_termination_1.
3486 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
3488 * sysdep.c (interruptible_wait_for_termination): New function
3489 which is like wait_for_termination, but allows keyboard
3492 * callproc.c (Fcall_process): Add (:file "file") as an option for
3494 (Fcall_process_region): Ditto.
3496 2011-04-30 Eli Zaretskii <eliz@gnu.org>
3498 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
3499 rather than `XVECTOR (FOO)->size'.
3501 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
3502 inttypes.h, as a gnulib replacement is used if it not available in
3505 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3507 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3508 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3509 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3511 * coding.c (coding_alloc_by_realloc): Error out if destination
3512 will grow beyond MOST_POSITIVE_FIXNUM.
3513 (decode_coding_emacs_mule): Abort if there isn't enough place in
3514 charbuf for the composition carryover bytes. Reserve an extra
3515 space for up to 2 characters produced in a loop.
3516 (decode_coding_iso_2022): Abort if there isn't enough place in
3517 charbuf for the composition carryover bytes.
3519 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3521 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3522 aborting when %lld or %lll format is passed.
3523 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3524 %llo or %llx format is passed. (Bug#8545)
3526 * window.c (window_scroll_line_based): Use a marker instead of
3527 simple variables to record original value of point. (Bug#7952)
3529 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3530 produced by %s or %c overflows available buffer space. (Bug#8545)
3532 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3534 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3535 (SIZE_MAX): Move defn after all includes, as they might #define it.
3537 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3539 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3541 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3543 * keyboard.c (Qdelayed_warnings_hook): Define.
3544 (command_loop_1): Run `delayed-warnings-hook'
3545 if Vdelayed_warnings_list is non-nil.
3546 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3547 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3549 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3551 * doprnt.c (doprnt): Don't return value smaller than the buffer
3552 size if the message was truncated. (Bug#8545).
3554 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3556 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
3557 (Fx_window_property): #if-0 the whole functions, not just the bodies.
3559 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3561 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3563 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3565 * makefile.w32-in: Update dependencies.
3567 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3569 Improve `doprnt' and its usage. (Bug#8545)
3570 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3571 `format_end'. Remove support for %l as a conversion specifier.
3572 Don't use xrealloc. Improve diagnostics when the %l size modifier
3573 is used. Update the commentary.
3575 * eval.c (verror): Simplify calculation of size_t.
3577 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3580 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3582 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3585 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3587 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3588 This makes this file independent of the recent pseudovector change.
3590 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3592 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3594 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3595 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3596 Remove unused local.
3597 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3599 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3600 GCC 4.6.0 optimizes based on type-based alias analysis.
3601 For example, if b is of type struct buffer * and v of type struct
3602 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3603 != &v->size, and therefore "v->size = 1; b->size = 2; return
3604 v->size;" must therefore return 1. This assumption is incorrect
3605 for Emacs, since it type-puns struct Lisp_Vector * with many other
3606 types. To fix this problem, this patch adds a new type struct
3607 vectorlike_header that documents the constraints on layout of vectors
3608 and pseudovectors, and helps optimizing compilers not get fooled
3609 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3610 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3611 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3613 (XSETPVECTYPE): Rewrite in terms of new macro.
3614 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3615 This is a bit clearer, and further avoids the possibility of
3616 undesirable aliasing.
3617 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3618 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3619 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3620 since Lisp_Subr is a special case (no "next" field).
3621 (ASIZE): Now uses header.size rather than size.
3622 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3623 to avoid the hassle of writing XVECTOR (foo)->header.size.
3624 (struct vectorlike_header): New type.
3625 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3626 object, to help avoid aliasing.
3627 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3628 (SUBRP): Likewise, since Lisp_Subr is a special case.
3629 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3630 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3631 (struct Lisp_Hash_Table): Combine first two members into a single
3632 struct vectorlike_header member. All uses of "size" and "next" members
3633 changed to be "header.size" and "header.next".
3634 * buffer.h (struct buffer): Likewise.
3635 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3636 * frame.h (struct frame): Likewise.
3637 * process.h (struct Lisp_Process): Likewise.
3638 * termhooks.h (struct terminal): Likewise.
3639 * window.c (struct save_window_data, struct saved_window): Likewise.
3640 * window.h (struct window): Likewise.
3641 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3642 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3643 * buffer.c (init_buffer_once): Likewise.
3644 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3646 * process.c (Fformat_network_address): Use local var for size,
3649 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3651 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3652 * data.c (atof): Remove decl; no longer used or needed.
3653 (digit_to_number): Move to lread.c.
3654 (Fstring_to_number): Use new string_to_number function, to be
3655 consistent with how the Lisp reader treats infinities and NaNs.
3656 Do not assume that floating-point numbers represent EMACS_INT
3657 without losing information; this is not true on most 64-bit hosts.
3658 Avoid double-rounding errors, by insisting on integers when
3659 parsing non-base-10 numbers, as the documentation specifies.
3660 * lisp.h (string_to_number): New decl, replacing ...
3661 (isfloat_string): Remove.
3662 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3663 (read1): Do not accept +. and -. as integers; this
3664 appears to have been a coding error. Similarly, do not accept
3665 strings like +-1e0 as floating point numbers. Do not report
3666 overflow for integer overflows unless the base is not 10 which
3667 means we have no simple and reliable way to continue.
3668 Break out the floating-point parsing into a new
3669 function string_to_number, so that Fstring_to_number parses
3670 floating point numbers consistently with the Lisp reader.
3671 (digit_to_number): Move here from data.c. Make it static inline.
3672 (E_CHAR, EXP_INT): Remove, replacing with ...
3673 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3674 (string_to_number): New function, replacing isfloat_string.
3675 This function checks for valid syntax and produces the resulting
3676 Lisp float number too. Rework it so that string-to-number
3677 no longer mishandles examples like "1.0e+". Use strtoumax,
3678 so that overflow for non-base-10 numbers is reported only when
3679 there's no portable and simple way to convert to floating point.
3681 * textprop.c (set_text_properties_1): Rewrite for clarity,
3682 and to avoid GCC warning about integer overflow.
3684 * intervals.h (struct interval): Use EMACS_INT for members
3685 where EMACS_UINT might cause problems. See
3686 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3687 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3688 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3690 (offset_intervals): Tell GCC not to worry about length overflow
3691 when negating a negative length.
3693 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3694 (overrun_check_free): Likewise.
3696 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3697 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3700 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3701 (gnutls_make_error): Rename local to avoid shadowing.
3702 (gnutls_emacs_global_deinit): ifdef out; not used.
3703 (Fgnutls_boot): Use const for pointer to readonly storage.
3704 Comment out unused local. Fix pointer signedness problems.
3706 * lread.c (openp): Don't stuff size_t into an 'int'.
3707 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3708 about possible signed overflow.
3710 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3711 (GDK_KEY_g): Don't define if already defined.
3712 (xg_prepare_tooltip): Avoid pointer signedness problem.
3713 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3715 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3716 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3718 * xfns.c (Fx_window_property): Simplify a bit,
3719 to make a bit faster and to avoid GCC 4.6.0 warning.
3720 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3722 * fns.c (internal_equal): Don't assume size_t fits in int.
3724 * alloc.c (compact_small_strings): Tighten assertion a little.
3726 Replace pEd with more-general pI, and fix some printf arg casts.
3727 * lisp.h (pI): New macro, generalizing old pEd macro to other
3728 conversion specifiers. For example, use "...%"pI"d..." rather
3729 than "...%"pEd"...".
3730 (pEd): Remove. All uses replaced with similar uses of pI.
3731 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3732 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3733 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3734 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3735 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3736 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3737 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3739 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3740 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3741 * print.c (safe_debug_print, print_object): Likewise.
3742 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3744 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3745 avoiding the 0 flag, which is not portable.
3746 * process.c (Fmake_network_process): Use pI to avoid cast.
3747 * region-cache.c (pp_cache): Likewise.
3748 * xdisp.c (decode_mode_spec): Likewise.
3749 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
3750 behavior on 64-bit hosts with printf arg.
3751 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
3752 (x_stop_queuing_selection_requests): Likewise.
3753 (x_get_window_property): Don't truncate byte count to an 'int'
3756 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3757 here, since it parses constructs like leading '-' and spaces,
3758 which are not wanted; and it overflows with large numbers.
3759 Instead, simply match F[0-9]+, which is what is wanted anyway.
3761 * alloc.c: Remove unportable assumptions about struct layout.
3762 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3763 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3764 (allocate_vectorlike, make_pure_vector): Use the new macros,
3765 plus offsetof, to remove unportable assumptions about struct layout.
3766 These assumptions hold on all porting targets that I know of, but
3767 they are not guaranteed, they're easy to remove, and removing them
3768 makes further changes easier.
3770 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3771 This doesn't fix a bug but makes the code clearer.
3772 (string_overrun_cookie): Now const. Use initializers that
3773 don't formally overflow signed char, to avoid warnings.
3774 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3775 can cause Emacs to crash when string overrun checking is enabled.
3776 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3777 multiple of sizeof (EMACS_INT); it need not be, if
3778 alignof(EMACS_INT) < sizeof (EMACS_INT).
3779 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
3781 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

3788 supposed to be handshaking. (Bug#8556)
3789 Reported by Paul Eggert <eggert@cs.ucla.edu>.

3801 * alloc.c (check_sblock, check_string_bytes)
3802 (check_string_free_list): Convert to standard C.
3804 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
3806 * w32.c (emacs_gnutls_push): Fix typo.
3808 2011-04-25 Eli Zaretskii <eliz@gnu.org>
3810 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
3811 "cast to pointer from integer of different size".
3813 Improve doprnt and its use in verror. (Bug#8545)
3814 * doprnt.c (doprnt): Document the set of format control sequences
3815 supported by the function. Use SAFE_ALLOCA instead of always
3818 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3819 is one byte too soon. Don't use xrealloc; instead xfree and
3822 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
3824 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
3827 * gnutls.c: Renamed global_initialized to
3828 gnutls_global_initialized. Added internals for the
3829 :verify-hostname-error, :verify-error, and :verify-flags
3830 parameters of `gnutls-boot' and documented those parameters in the
3831 docstring. Start callback support.
3832 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
3833 unless a fatal error occurred. Call gnutls_alert_send_appropriate
3834 on error. Return error code.
3835 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
3836 (emacs_gnutls_read): Likewise.
3837 (Fgnutls_boot): Return handshake error code.

3910 Improve overflow protection. Support `l' modifier for integer
3911 conversions. Support %l conversion. Don't assume an EMACS_INT
3912 argument for integer conversions and for %c.

3924 * eval.c (internal_lisp_condition_case): Include the handler
3925 representation in the error message.
3926 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
3927 when breaking from the loop.
3929 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
3931 * callint.c (Fcall_interactively): When displaying error message
3932 about invalid control letter, pass the character's codepoint, not
3933 a pointer to its multibyte form. Improve display of the character
3934 in octal and display also its hex code.
3936 * character.c (char_string): Use %x to display the (unsigned)
3937 codepoint of an invalid character, to avoid displaying a bogus
3940 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
3941 `error', not SYMBOL_NAME itself.
3943 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
3944 character arguments to `error'.
3946 * charset.c (check_iso_charset_parameter): Fix incorrect argument
3947 to `error' in error message about FINAL_CHAR argument. Make sure
3948 FINAL_CHAR is a character, and use %c when it is passed as
3949 argument to `error'.
3951 2011-04-23 Eli Zaretskii <eliz@gnu.org>
3953 * s/ms-w32.h (localtime): Redirect to sys_localtime.
3955 * w32.c: Include <time.h>.

4013 Define only if needed.
4015 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

4030 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
4031 so that we aren't warned about unused symbols.

4046 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
4047 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
4048 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
4050 * xmenu.c (menu_help_callback): Pointer type fixes.
4051 Use const pointers when pointing at readonly data. Avoid pointer

4062 * keyboard.c (make_lispy_event): Remove unused local var.
4064 * frame.c, frame.h (x_get_resource_string): Bring this back, but
4065 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
4067 * bitmaps: Change bitmaps from unsigned char back to the X11
4068 compatible char. Avoid the old compiler warnings about
4069 out-of-range initializers by using, for example, '\xab' rather
4072 * xgselect.c (xgselect_initialize): Check vs interface
4073 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
4075 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.

4100 2011-04-16 Eli Zaretskii <eliz@gnu.org>
4102 * gnutls.c (Fgnutls_boot): Don't pass Lisp_Object to `error'.

4138 * nsfont.m: Fixed bugs in ns_get_family and
4139 ns_descriptor_to_entity that were caused by using free to
4140 deallocate memory blocks that were allocated by xmalloc (via
4141 xstrdup). This caused Emacs to crash when compiled with
4142 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
4143 --enable-checking=xmallocoverrun). xfree is now used to
4144 deallocate these memory blocks.

4614 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
4615 when at ZV. (Bug#8487)
4617 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
4619 * charset.c (Fclear_charset_maps): Use xfree instead of free.
4621 * keyboard.c (parse_tool_bar_item): Likewise.
4622 * sound.c (sound_cleanup, alsa_close): Likewise.
4623 * termcap.c (tgetent): Likewise.
4624 * xfns.c (x_default_font_parameter): Likewise.
4625 * xsettings.c (read_and_apply_settings): Likewise.
4627 * alloc.c (overrun_check_malloc, overrun_check_realloc)
4628 (overrun_check_free): Protoize.
4630 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
4632 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
4633 since callers should never pass a negative size.
4634 Change the signature to match that of plain 'read' and 'write'; see
4635 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
4636 * lisp.h: Update prototypes of emacs_write and emacs_read.
4638 2011-04-11 Eli Zaretskii <eliz@gnu.org>
4640 * xdisp.c (redisplay_window): Don't try to determine the character
4641 position of the scroll margin if the window start point w->startp
4642 is outside the buffer's accessible region. (Bug#8468)
4644 2011-04-10 Eli Zaretskii <eliz@gnu.org>
4646 Fix write-region and its subroutines for buffers > 2GB.
4647 * fileio.c (a_write, e_write): Modify declaration of arguments and
4648 local variables to support buffers larger than 2GB.
4649 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
4651 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4652 argument, local variables, and return value.
4654 * lisp.h: Update prototypes of emacs_write and emacs_read.
4656 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4658 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4660 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4662 Fix more problems found by GCC 4.6.0's static checks.
4664 * xdisp.c (vmessage): Use a better test for character truncation.
4666 * charset.c (load_charset_map): <, not <=, for optimization,
4667 and to avoid potential problems with integer overflow.
4668 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4669 * casetab.c (set_identity, shuffle): Likewise.
4670 * editfns.c (Fformat): Likewise.
4671 * syntax.c (skip_chars): Likewise.
4673 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4674 This also lets GCC 4.6.0 generate slightly better loop code.
4676 * callint.c (Fcall_interactively): <, not <=, for optimization.
4677 (Fcall_interactively): Count the number of arguments produced,
4678 not the number of arguments given. This is simpler and lets GCC
4679 4.6.0 generate slightly better code.
4681 * ftfont.c: Distingish more carefully between FcChar8 and char.
4682 The previous code passed unsigned char * to a functions like
4683 strlen and xstrcasecmp that expect char *, which does not
4684 conform to the C standard.
4685 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4686 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4687 char * when the C standard requires it.
4689 * keyboard.c (read_char): Remove unused var.
4691 * eval.c: Port to Windows vsnprintf (Bug#8435).
4693 (SIZE_MAX): Define if the headers do not.
4694 (verror): Do not give up if vsnprintf returns a negative count.
4695 Instead, grow the buffer. This ports to Windows vsnprintf, which
4696 does not conform to C99. Problem reported by Eli Zaretskii.
4697 Also, simplify the allocation scheme, by avoiding the need for
4698 calling realloc, and removing the ALLOCATED variable.
4700 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4702 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4703 But keep the doprint source code for now, as we might revamp it
4704 and use it again (Bug#8435).
4705 * lisp.h (doprnt): Remove.
4706 * Makefile.in (base_obj): Remove doprnt.o.
4707 * deps.mk (doprnt.o): Remove.
4709 error: Print 32- and 64-bit integers portably (Bug#8435).
4710 Without this change, on typical 64-bit hosts error ("...%d...", N)
4711 was used to print both 32- and 64-bit integers N, which relied on
4713 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4715 * lisp.h (error, verror): Mark as printf-like functions.
4716 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4717 Report overflow in size calculations when allocating printf buffer.
4718 Do not truncate output string at its first null byte.
4719 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4720 Truncate the output at a character boundary, since vsnprintf does not
4722 * charset.c (check_iso_charset_parameter): Convert internal
4723 character to string before calling 'error', since %c now has the
4725 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4726 overflow when computing char to be passed to 'error'. Do not
4727 pass Lisp_Object to 'error'; pass the integer instead.
4728 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4729 formatted with plain %d.
4731 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4733 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4735 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4737 * xterm.c (x_catch_errors): Remove duplicate declaration.
4739 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4741 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4743 2011-04-10 Jim Meyering <meyering@redhat.com>
4745 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4746 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4747 return ssize_t not "int", and use size_t as the buffer length.
4748 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4749 * gnutls.h: Update declarations.
4750 * process.c (read_process_output): Use ssize_t, to match.
4751 (send_process): Likewise.
4753 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4755 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4757 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4759 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4760 Use unsigned char, to match FcChar8 type definition.
4762 * xterm.c (handle_one_xevent):
4763 * xmenu.c (create_and_show_popup_menu):
4764 * xselect.c (x_decline_selection_request)
4765 (x_reply_selection_request): Avoid type-punned deref of X events.
4767 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4769 Fix some uses of `int' instead of EMACS_INT.
4770 * search.c (string_match_1, fast_string_match)
4771 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4772 (scan_buffer, find_next_newline_no_quit)
4773 (find_before_next_newline, search_command, Freplace_match)
4774 (Fmatch_data): Make some `int' variables be EMACS_INT.
4776 * xdisp.c (display_count_lines): 3rd argument and return value now
4777 EMACS_INT. All callers changed.
4778 (pint2hrstr): Last argument is now EMACS_INT.
4780 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4781 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4782 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

4792 (encode_designation_at_bol, encode_coding_iso_2022)
4793 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4794 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4796 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4797 (encode_invocation_designation): Last argument P_NCHARS is now
4799 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4800 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4802 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4805 * ccl.c (Fccl_execute_on_string): Declare some variables
4808 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

4816 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4818 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4820 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4822 * keyboard.c (read_char): Call Lisp function help-form-show,
4823 instead of using internal_with_output_to_temp_buffer.
4824 (Qhelp_form_show): New var.
4825 (syms_of_keyboard): Use DEFSYM macro.
4827 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4829 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4831 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4833 * process.c (Flist_processes): Remove to Lisp.
4834 (list_processes_1): Delete.

4840 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4842 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4844 Fix more problems found by GCC 4.6.0's static checks.
4846 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4848 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4850 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4852 * xdisp.c (vmessage): Mark as a printf-like function.
4854 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4856 * sound.c (sound_warning): Don't crash if arg contains a printf format.

4859 printf-like functions.
4860 (tiff_load): Add casts to remove these marks before passing them
4861 to system-supplied API.
4863 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4865 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4866 This avoids several warnings with gcc -Wstrict-overflow.
4867 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4868 directly, rather than having caller test rule sign. This avoids
4869 some unnecessary tests.
4870 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4871 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4872 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4874 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4875 (xfont_open): Avoid unnecessary tests.
4877 * composite.c (composition_gstring_put_cache): Use unsigned integer.

4886 by using the new macro.
4888 * textprop.c (set_text_properties_1): Change while to do-while,
4889 since the condition is always true at first.

4904 * syntax.c (scan_words): Remove var that was set but not used.
4905 (update_syntax_table): Use unsigned instead of int.
4907 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

4916 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
4917 (font_score): Avoid potential overflow in diff calculation.
4919 * fns.c (substring_both): Remove var that is set but not used.
4920 (sxhash): Redo loop for clarity and to avoid wraparound warning.
4922 * eval.c (funcall_lambda): Rename local to avoid shadowing.
4924 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
4925 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
4926 can always succeed if overflow has undefined behavior.
4928 * search.c (boyer_moore, wordify): Remove vars set but not used.
4929 (wordify): Omit three unnecessary tests.
4931 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
4932 All callers changed. This avoids the need for an unused var.
4934 * casefiddle.c (casify_region): Remove var that is set but not used.
4936 * dired.c (file_name_completion): Remove var that is set but not used.
4938 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
4940 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
4941 (Finsert_file_contents): Remove unnecessary code checking fd.
4943 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
4944 Check for integer overflow on size calculations.
4946 * buffer.c (Fprevious_overlay_change): Remove var that is set
4949 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
4950 Remove vars that are set but not used.
4951 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
4952 (timer_check_2): Mark vars as initialized.
4954 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
4956 * image.c (lookup_image): Remove var that is set but not used.
4957 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
4959 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
4960 that are set but not used.
4962 * xfns.c (make_invisible_cursor): Don't return garbage
4963 if XCreateBitmapFromData fails (Bug#8410).

4982 * coding.c: Remove vars that are set but not used.
4983 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
4984 All callers changed.
4985 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

4987 (decode_coding_charset): Remove vars that are set but not used.
4989 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
4990 that is set but not used.
4992 * print.c (print_object): Remove var that is set but not used.
4994 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
4995 The gnulib version avoids calling malloc in the usual case,
4996 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
4997 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
4998 * filelock.c (current_lock_owner): Likewise.
4999 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

5008 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
5009 first non-nil return value).

5013 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
5014 if not defined (Bug#8403).
5016 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
5018 * xdisp.c (display_count_lines): Remove parameter `start',
5019 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5020 (get_char_face_and_encoding): Remove parameter `multibyte_p',

5025 (get_per_char_metric): Remove parameter `f', unused since
5026 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

5030 do not dereference NULL upon failed strdup
5031 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

5056 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
5058 (syms_of_lread): Declare `lexical-binding'.
5060 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
5062 * keyboard.c (eval_dyn): New fun.
5063 (menu_item_eval_property): Use it.
5065 * image.c (parse_image_spec): Use Ffunctionp.
5067 * fns.c (concat, mapcar1): Accept byte-code-functions.
5069 * eval.c (Fsetq): Handle lexical vars.
5070 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
5071 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
5072 (FletX, Flet): Obey lexical binding.
5073 (Fcommandp): Handle closures.
5074 (Feval): New `lexical' arg.
5075 (eval_sub): New function extracted from Feval. Use it almost
5076 everywhere where Feval was used. Look up vars in lexical env.
5078 (Ffunctionp): Move from subr.el.
5079 (Ffuncall): Handle closures.
5080 (apply_lambda): Remove `eval_flags'.
5081 (funcall_lambda): Handle closures and new byte-code-functions.
5082 (Fspecial_variable_p): New function.
5083 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
5084 but without exporting it to Lisp.
5086 * doc.c (Fdocumentation, store_function_docstring):
5087 * data.c (Finteractive_form): Handle closures.
5089 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
5092 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
5094 (exec_byte_code): New function extracted from Fbyte_code to handle new
5095 calling convention for byte-code-functions. Add new byte-codes.
5097 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
5099 * alloc.c (Fmake_symbol): Init new `declared_special' field.
5101 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5103 * xdisp.c (redisplay_internal): Fix prototype.
5105 2011-03-31 Eli Zaretskii <eliz@gnu.org>
5107 * xdisp.c (SCROLL_LIMIT): New macro.
5108 (try_scrolling): Use it when setting scroll_limit.
5109 Limit scrolling to 100 screen lines.
5110 (redisplay_window): Even when falling back on "recentering",
5111 position point in the window according to scroll-conservatively,
5112 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
5114 (try_scrolling): When point is above the window, allow searching
5115 as far as scroll_max, or one screenful, to compute vertical
5116 distance from PT to the scroll margin position. This prevents
5117 try_scrolling from unnecessarily failing when
5118 scroll-conservatively is set to a value slightly larger than the
5119 window height. Clean up the case of PT below the margin at bottom
5120 of window: scroll_max can no longer be INT_MAX. When aggressive
5121 scrolling is in use, don't let point enter the opposite scroll
5122 margin as result of the scroll.
5123 (syms_of_xdisp) <scroll-conservatively>: Document the
5124 threshold of 100 lines for never-recentering scrolling.
5126 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
5128 * dispextern.h (move_it_by_lines):
5129 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
5130 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
5131 (message_log_check_duplicate): Remove parameters `prev_bol' and
5132 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
5133 (redisplay_internal): Remove parameter `preserve_echo_area',
5134 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
5136 * indent.c (Fvertical_motion):
5137 * window.c (window_scroll_pixel_based, Frecenter):
5138 Don't pass `need_y_p' to `move_it_by_lines'.
5140 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
5142 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
5143 steal a few bits to be more compact.
5144 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
5145 Remove unneeded casts.
5147 * bytecode.c (Fbyte_code): CAR and CDR can GC.
5149 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
5151 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
5152 binding" message (bug#7967).
5154 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
5156 Fix more problems found by GCC 4.6.0's static checks.
5158 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
5159 Remove unused local var.
5161 * editfns.c (Fmessage_box): Remove unused local var.
5163 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
5164 (note_mode_line_or_margin_highlight, note_mouse_highlight):
5165 Omit unused local vars.
5166 * window.c (shrink_windows): Omit unused local var.
5167 * menu.c (digest_single_submenu): Omit unused local var.
5168 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
5169 Omit unused local var.
5171 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
5172 Don't assume string length fits in int.
5173 (keyremap_step, read_key_sequence): Use size_t for sizes.
5174 (read_key_sequence): Don't check last_real_key_start redundantly.
5176 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
5177 instead of alloca (Bug#8344).
5179 * eval.c (Fbacktrace): Don't assume nargs fits in int.
5180 (Fbacktrace_frame): Don't assume nframes fits in int.
5182 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
5184 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
5187 * term.c (produce_glyphless_glyph): Remove unnecessary test.
5189 * cm.c (calccost): Turn while-do into do-while, for clarity.
5191 * keyboard.c (syms_of_keyboard): Use the same style as later
5192 in this function when indexing through an array. This also
5193 works around GCC bug 48267.
5195 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
5197 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
5199 * chartab.c (sub_char_table_ref_and_range): Redo for slight
5200 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
5202 * keyboard.c, keyboard.h (num_input_events): Now size_t.
5203 This avoids undefined behavior on integer overflow, and is a bit
5204 more convenient anyway since it is compared to a size_t variable.
5206 Variadic C functions now count arguments with size_t, not int.
5207 This avoids an unnecessary limitation on 64-bit machines, which
5208 caused (substring ...) to crash on large vectors (Bug#8344).
5209 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
5210 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
5211 All variadic functions and their callers changed accordingly.
5212 (struct gcpro.nvars): Now size_t, not int. All uses changed.
5213 * data.c (arith_driver, float_arith_driver): Likewise.
5214 * editfns.c (general_insert_function): Likewise.
5215 * eval.c (struct backtrace.nargs, interactive_p)
5216 (internal_condition_case_n, run_hook_with_args, apply_lambda)
5217 (funcall_lambda, mark_backtrace): Likewise.
5218 * fns.c (concat): Likewise.
5219 * frame.c (x_set_frame_parameters): Likewise.
5220 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
5221 0 if not found, not -1. All callers changed.
5223 * alloc.c (garbage_collect): Don't assume stack size fits in int.
5224 (stack_copy_size): Now size_t, not int.
5225 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
5227 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
5229 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
5230 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5231 All callers changed.
5233 * lisp.h (multibyte_char_to_unibyte):
5234 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
5235 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
5236 * character.h (CHAR_TO_BYTE8):
5237 * cmds.c (internal_self_insert):
5238 * editfns.c (general_insert_function):
5239 * keymap.c (push_key_description):
5240 * search.c (Freplace_match):
5241 * xdisp.c (message_dolog, set_message_1): All callers changed.
5243 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5245 * keyboard.c (safe_run_hook_funcall): New function.
5246 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
5247 don't set the hook to nil, but remove the offending function instead.
5248 (Qcommand_hook_internal): Remove, unused.
5249 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
5250 Vcommand_hook_internal.
5252 * eval.c (enum run_hooks_condition): Remove.
5253 (funcall_nil, funcall_not): New functions.
5254 (run_hook_with_args): Call each function through a `funcall' argument.
5255 Remove `cond' argument, now redundant.
5256 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
5257 (Frun_hook_with_args_until_failure): Adjust accordingly.
5258 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

5264 * print.c (strout): Remove parameter `multibyte', unused since
5265 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
5267 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
5268 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
5269 All callers changed.
5271 * w32.c (_wsa_errlist): Use braces for struct initializers.
5273 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
5274 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
5275 All callers changed.
5276 (string_buffer_position): Likewise. Also, make static (it's never
5277 used outside xdisp.c).
5278 (cursor_row_p): Remove parameter `w', unused since
5279 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
5280 (decode_mode_spec): Remove parameter `precision', introduced during
5281 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
5282 All callers changed.
5284 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
5286 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
5288 2011-03-27 Anders Lindgren <andlind@gmail.com>

5292 (ns_update_auto_hide_menu_bar): New functions.
5293 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
5294 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and
5295 ns_constrain_all_frames.

5301 * nsmenu.m (runDialogAt): Remove argument to timer_check.
5303 2011-03-27 Glenn Morris <rgm@gnu.org>
5305 * syssignal.h: Replace RETSIGTYPE with void.
5306 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
5307 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
5308 Replace SIGTYPE with void everywhere.
5309 * s/usg5-4-common.h (SIGTYPE): Remove definition.

5312 2011-03-26 Eli Zaretskii <eliz@gnu.org>
5314 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
5315 flag as a prerequisite for invoking try_scrolling. (Bug#6671)

5320 global variable `wget_enum_handle'.
5322 * keymap.c (describe_vector): Remove parameters `indices' and
5323 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

5331 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
5333 * keyboard.c (read_char):
5334 * w32menu.c (w32_menu_display_help):
5335 * xmenu.c (show_help_event, menu_help_callback):
5336 Adjust calls to `show_help_echo'.

5339 * keyboard.c (readable_events):
5340 * process.c (wait_reading_process_output):
5341 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
5343 * insdel.c (adjust_markers_gap_motion):
5344 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
5345 (gap_left, gap_right): Don't call it.
5347 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
5349 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
5350 incurred during fontification.
5352 2011-03-25 Juanma Barranquero <lekktu@gmail.com>
5354 * buffer.c (defvar_per_buffer): Remove unused parameter `doc'.

5418 2011-03-23 Julien Danjou <julien@danjou.info>
5420 * term.c (Fsuspend_tty, Fresume_tty):
5421 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
5422 * window.c (temp_output_buffer_show):
5423 * insdel.c (signal_before_change):
5424 * frame.c (Fhandle_switch_frame):

5428 * cmds.c (internal_self_insert):
5429 * callint.c (Fcall_interactively):
5430 * buffer.c (Fkill_all_local_variables):
5431 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
5433 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
5434 unconditionnaly since it does the check itself.
5436 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
5438 Fix more problems found by GCC 4.5.2's static checks.
5440 * coding.c (encode_coding_raw_text): Avoid unnecessary test
5441 the first time through the loop, since we know p0 < p1 then.
5442 This also avoids a gcc -Wstrict-overflow warning.
5444 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
5445 leading to a memory leak, possible in functions like
5446 load_charset_map_from_file that can allocate an unbounded number
5447 of objects (Bug#8318).
5449 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
5450 that could (at least in theory) be that large.
5452 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
5453 This is less likely to overflow, and avoids undefined behavior if
5454 overflow does occur. All callers changed. Use strtoul to scan
5455 for the unsigned long integer.
5456 (pint2hrstr): Simplify and tune code slightly.
5457 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
5459 * scroll.c (do_scrolling): Work around GCC bug 48228.
5460 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
5462 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
5463 This also avoids a warning with gcc -Wstrict-overflow.
5464 (validate_x_resource_name): Simplify count usage.
5465 This also avoids a warning with gcc -Wstrict-overflow.
5467 * fileio.c (Fcopy_file): Report error if fchown or fchmod
5470 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
5472 * process.c (Fmake_network_process): Use socklen_t, not int,
5473 where POSIX says socklen_t is required in portable programs.
5474 This fixes a porting bug on hosts like 64-bit HP-UX, where
5475 socklen_t is wider than int (Bug#8277).
5476 (Fmake_network_process, server_accept_connection):
5477 (wait_reading_process_output, read_process_output):
5480 * process.c: Rename or move locals to avoid shadowing.
5481 (list_processes_1, Fmake_network_process):
5482 (read_process_output_error_handler, exec_sentinel_error_handler):
5483 Rename or move locals.
5484 (Fmake_network_process): Define label "retry_connect" only if needed.
5485 (Fnetwork_interface_info): Fix pointer signedness.
5486 (process_send_signal): Add cast to avoid pointer signedness problem.
5487 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
5488 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
5490 Make tparam.h and terminfo.c consistent.
5491 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
5492 Include tparam.h instead, since it declares them.
5493 * cm.h (PC): Remove extern decl; tparam.h now does this.
5494 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
5495 * terminfo.c: Include tparam.h, to check interfaces.
5496 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
5497 (tparam): Adjust signature to match interface in tparam.h;
5498 this removes some undefined behavior. Check that outstring and len
5499 are zero, which they always are with Emacs.
5500 * tparam.h (PC, BC, UP): New extern decls.
5502 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5503 (xftfont_open): Rename locals to avoid shadowing.
5505 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
5506 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

5551 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5552 clobbering (Bug#8298).

5730 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5731 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5732 to use the following functions instead of these macros.
5733 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5734 EMACS_INT, since callers assume the returned value fits in int.
5735 (upcase1): Likewise, for UPCASE_TABLE.
5736 (uppercasep, lowercasep, upcase): New static inline functions.
5737 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

5747 (regex_compile, re_match_2_internal): Mark locals as initialized.
5748 (RETALLOC_IF): Define only if needed.
5749 (WORDCHAR_P): Likewise. This one is never needed, but is used
5750 only in a comment talking about a compiler bug, so put inside
5751 the #if 0 of that comment.
5752 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5753 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5756 * search.c (boyer_moore): Rename locals to avoid shadowing.

5781 gcpro1, gcpro2, etc.
5782 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5784 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5785 argument, for consistency with GCPRO2_VAR, etc: it is now the
5786 prefix of the variable, not the variable itself. All uses
5788 * dired.c (directory_files_internal, file_name_completion):
5789 Rename locals to avoid shadowing.
5791 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5792 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5793 dired.c's scmp function, had undefined behavior.
5794 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5795 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5796 * buffer.h: ... to here, because these macros use current_buffer,
5797 and the new implementation with inline functions needs to have
5798 current_buffer in scope now, rather than later when the macros
5800 (downcase, upcase1): New static inline functions.
5801 (DOWNCASE, UPCASE1): Reimplement using these functions.
5802 This avoids undefined behavior in expressions like
5803 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5804 from race conditions in accessing the global variables
5805 case_temp1 and case_temp2.
5806 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5807 * lisp.h (case_temp1, case_temp2): Remove their decls.
5808 * character.h (ASCII_CHAR_P): Move from here ...
5809 * lisp.h: ... to here, so that the inline functions mentioned
5812 * dired.c (directory_files_internal_unwind): Now static.
5814 * fileio.c (file_name_as_directory, directory_file_name):
5815 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5817 (file_name_as_directory): Use const pointers when appropriate.
5818 (Fexpand_file_name): Likewise. In particular, newdir might
5819 point at constant storage, so make it a const pointer.
5820 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5821 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5823 (Fset_file_times, Finsert_file_contents, auto_save_error):
5824 Rename locals to avoid shadowing.

5832 * lisp.h (verify_bytepos, count_markers): New decls,
5833 so that gcc does not warn that these functions aren't declared.
5835 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5836 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

5841 (lock_file_1): Rename local to avoid shadowing.
5843 * buffer.c (fix_overlays_before): Mark locals as initialized.
5844 (fix_start_end_in_overlays): Likewise. This function should be
5845 simplified by using pointers-to-pointers, but that's a different
5847 (switch_to_buffer_1): Now static.
5848 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5849 (report_overlay_modification): Rename locals to avoid shadowing.
5851 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5852 Fix pointer signedness issue.
5853 (sys_subshell): Mark local as volatile if checking for lint,
5854 to suppress a gcc -Wclobbered warning that does not seem to be right.
5855 (MAXPATHLEN): Define only if needed.
5857 * process.c (serial_open, serial_configure): Move decls from here ...
5858 * systty.h: ... to here, so that they can be checked.
5860 * fns.c (get_random, seed_random): Move extern decls from here ...
5861 * lisp.h: ... to here, so that they can be checked.
5863 * sysdep.c (reset_io): Now static.

5873 Rename locals to avoid shadowing.
5875 * keyboard.c: Declare functions static if they are not used elsewhere.
5876 (echo_char, echo_dash, cmd_error, top_level_2):
5877 (poll_for_input, handle_async_input): Now static.
5878 (read_char, kbd_buffer_get_event, make_lispy_position):

5897 if GCC considers string literals to be constants.
5899 * lisp.h (fatal_error_signal): Add decl, since it's exported.
