[bpt/emacs.git] / src / ChangeLog
1 2011-06-18 Paul Eggert <eggert@cs.ucla.edu>
2
3 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4 Use much-faster test for byte-length change.
5 Don't assume string byte-length fits in 'int'.
6 Check that character arg fits in 'int'.
7
8 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9
10 * fns.c (concat): Catch string overflow earlier.
11 Do not rely on integer wraparound.
12
13 * dispextern.h (struct it.overlay_strings_charpos): EMACS_INT, not int.
14
15 2011-06-17 Paul Eggert <eggert@cs.ucla.edu>
16
17 * dispextern.h (struct it.selective): Now EMACS_INT, not int.
18 * xdisp.c (forward_to_next_line_start)
19 (back_to_previous_visible_line_start)
20 (reseat_at_next_visible_line_start, next_element_from_buffer):
21 Don't arbitrarily truncate the value of 'selective' to int.
22
23 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
24
25 * composite.c: Don't truncate sizes to 'int'.
26 (composition_gstring_p, composition_reseat_it)
27 (composition_adjust_point): Use EMACS_INT, not int.
28 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
29 not EMACS_UINT, for indexes.
30
31 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
32
33 * buffer.c: Include <verify.h>.
34 (struct sortvec.priority, struct sortstr.priority):
35 Now EMACS_INT, not int.
36 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
37 (struct sortstr.size, record_overlay_string)
38 (struct sortstrlist.size, struct sortlist.used):
39 Don't truncate size to int.
40 (record_overlay_string): Check for size-calculation overflow.
41 (init_buffer_once): Check at compile-time, not run-time.
42
43 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
44
45 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
46 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
47 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
48
49 Improve buffer-overflow checking (Bug#8873).
50 * fileio.c (Finsert_file_contents):
51 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
52 Remove the old (too-loose) buffer overflow checks.
53 They weren't needed, since make_gap checks for buffer overflow.
54 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
55 The old code merely checked for Emacs fixnum overflow, and relied
56 on undefined (wraparound) behavior. The new code avoids undefined
57 behavior, and also checks for ptrdiff_t and/or size_t overflow.
58
59 * editfns.c (Finsert_char): Don't dump core with very negative counts.
60 Tune. Don't use wider integers than needed. Don't use alloca.
61 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
62
63 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
64
65 * insdel.c, lisp.h (buffer_overflow): New function.
66 (insert_from_buffer_1, replace_range, replace_range_2):
67 * insdel.c (make_gap_larger):
68 * editfns.c (Finsert_char):
69 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
70
71 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
72
73 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
74
75 Integer overflow and signedness fixes (Bug#8873).
76
77 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
78 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
79
80 * fileio.c: Don't assume EMACS_INT fits in off_t.
81 (emacs_lseek): New static function.
82 (Finsert_file_contents, Fwrite_region): Use it.
83 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
84
85 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
86
87 * fns.c: Don't overflow int when computing a list length.
88 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
89 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
90 truncation on 64-bit hosts. Check for QUIT every
91 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
92 faster and is responsive enough.
93 (Flength): Report an error instead of overflowing an integer.
94 (Fsafe_length): Return a float if the value is not representable
95 as a fixnum. This shouldn't happen except in contrived situations.
96 (Fnthcdr, Fsort): Don't assume list length fits in int.
97 (Fcopy_sequence): Don't assume vector length fits in int.
98
99 * alloc.c: Check that resized vectors' lengths fit in fixnums.
100 (header_size, word_size): New constants.
101 (allocate_vectorlike): Don't check size overflow here.
102 (allocate_vector): Check it here instead, since this is the only
103 caller of allocate_vectorlike that could cause overflow.
104 Check that the new vector's length is representable as a fixnum.
105
106 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
107 The previous code was bogus. For example, next_almost_prime (32)
108 returned 39, which is undesirable as it is a multiple of 3; and
109 next_almost_prime (24) returned 25, which is a multiple of 5 so
110 why was the code bothering to check for multiples of 7?
111
112 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
113
114 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
115
116 Variadic C functions now count arguments with ptrdiff_t.
117 This partly undoes my 2011-03-30 change, which replaced int with size_t.
118 Back then I didn't know that the Emacs coding style prefers signed int.
119 Also, in the meantime I found a few more instances where arguments
120 were being counted with int, which may truncate counts on 64-bit
121 machines, or EMACS_INT, which may be unnecessarily wide.
122 * lisp.h (struct Lisp_Subr.function.aMANY)
123 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
124 Arg counts are now ptrdiff_t, not size_t.
125 All variadic functions and their callers changed accordingly.
126 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
127 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
128 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
129 * callint.c (Fcall_interactively): Check arg count for overflow,
130 to avoid potential buffer overrun. Use signed char, not 'int',
131 for 'varies' array, so that we needn't bother to check its size
132 calculation for overflow.
133 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
134 * eval.c (apply_lambda):
135 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
136 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
137 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
138
139 * callint.c (Fcall_interactively): Don't use index var as event count.
140
141 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
142 * mem-limits.h (SIZE): Remove; no longer used.
143
144 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
145
146 Remove unnecessary casts.
147 * xterm.c (x_term_init):
148 * xfns.c (x_set_border_pixel):
149 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
150 These aren't needed now that we assume ANSI C.
151
152 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
153 It's more likely to cause problems (due to unsigned overflow)
154 than to cure them.
155
156 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
157
158 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
159
160 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
161
162 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
163
164 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
165
166 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
167
168 GLYPH_CODE_FACE returns EMACS_INT, not int.
169 * dispextern.h (merge_faces):
170 * xfaces.c (merge_faces):
171 * xdisp.c (get_next_display_element, next_element_from_display_vector):
172 Don't assume EMACS_INT fits in int.
173
174 * character.h (CHAR_VALID_P): Remove unused parameter.
175 * fontset.c, lisp.h, xdisp.c: All uses changed.
176
177 * editfns.c (Ftranslate_region_internal): Omit redundant test.
178
179 * fns.c (concat): Minor tuning based on overflow analysis.
180 This doesn't fix any bugs. Use int to hold character, instead
181 of constantly refetching from Emacs object. Use XFASTINT, not
182 XINT, for value known to be a character. Don't bother comparing
183 a single byte to 0400, as it's always less.
184
185 * floatfns.c (Fexpt):
186 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
187
188 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
189 for characters.
190
191 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
192
193 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
194 Without this fix, on a 64-bit host (aset S 0 4294967386) would
195 incorrectly succeed when S was a string, because 4294967386 was
196 truncated before it was used.
197
198 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
199 Otherwise, an out-of-range integer could cause undefined behavior
200 on a 64-bit host.
201
202 * composite.c: Use int, not EMACS_INT, for characters.
203 (fill_gstring_body, composition_compute_stop_pos): Use int, not
204 EMACS_INT, for values that are known to be in character range.
205 This doesn't fix any bugs but is the usual style inside Emacs and
206 may generate better code on 32-bit machines.
207
208 Make sure a 64-bit char is never passed to ENCODE_CHAR.
209 This is for reasons similar to the recent CHAR_STRING fix.
210 * charset.c (Fencode_char): Check that character arg is actually
211 a character. Pass an int to ENCODE_CHAR.
212 * charset.h (ENCODE_CHAR): Verify that the character argument is no
213 wider than 'int', as a compile-time check to prevent future regressions
214 in this area.
215
216 * character.c (char_string): Remove unnecessary casts.
217
218 Make sure a 64-bit char is never passed to CHAR_STRING.
219 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
220 by silently ignoring the top 32 bits, allowing some values
221 that were far too large to be valid characters.
222 * character.h: Include <verify.h>.
223 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
224 arguments are no wider than unsigned, as a compile-time check
225 to prevent future regressions in this area.
226 * data.c (Faset):
227 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
228 (Fsubst_char_in_region):
229 * fns.c (concat):
230 * xdisp.c (decode_mode_spec_coding):
231 Adjust to CHAR_STRING's new requirement.
232 * editfns.c (Finsert_char, Fsubst_char_in_region):
233 * fns.c (concat): Check that character args are actually
234 characters. Without this test, these functions did the wrong
235 thing with wildly out-of-range values on 64-bit hosts.
236
237 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
238 These casts should not be needed on 32-bit hosts, either.
239 * keyboard.c (read_char):
240 * lread.c (Fload): Remove casts to unsigned.
241
242 * lisp.h (UNSIGNED_CMP): New macro.
243 This fixes comparison bugs on 64-bit hosts.
244 (ASCII_CHAR_P): Use it.
245 * casefiddle.c (casify_object):
246 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
247 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
248 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
249 * dispextern.h (FACE_FROM_ID):
250 * keyboard.c (read_char): Use UNSIGNED_CMP.
251
252 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
253 not to EMACS_INT, to avoid GCC warning.
254
255 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
256
257 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
258 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
259 isn't needed on 32-bit machines.
260
261 * buffer.c (Fgenerate_new_buffer_name):
262 Use EMACS_INT for count, not int.
263 (advance_to_char_boundary): Return EMACS_INT, not int.
264
265 * data.c (Qcompiled_function): Now static.
266
267 * window.c (window_body_lines): Now static.
268
269 * image.c (gif_load): Rename local to avoid shadowing.
270
271 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
272 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
273 * alloc.c (make_save_value): Integer argument is now of type
274 ptrdiff_t, not int.
275 (mark_object): Use ptrdiff_t, not int.
276 * lisp.h (pD): New macro.
277 * print.c (print_object): Use it.
278
279 * alloc.c: Use EMACS_INT, not int, to count objects.
280 (total_conses, total_markers, total_symbols, total_vector_size)
281 (total_free_conses, total_free_markers, total_free_symbols)
282 (total_free_floats, total_floats, total_free_intervals)
283 (total_intervals, total_strings, total_free_strings):
284 Now EMACS_INT, not int. All uses changed.
285 (Fgarbage_collect): Compute overall total using a double, so that
286 integer overflow is less likely to be a problem. Check for overflow
287 when converting back to an integer.
288 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
289 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
290 These were 'int' variables that could overflow on 64-bit hosts;
291 they were never used, so remove them instead of repairing them.
292 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
293 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
294 Previously, this ceilinged at INT_MAX, but that doesn't work on
295 64-bit machines.
296 (allocate_pseudovector): Don't use EMACS_INT when int would do.
297
298 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
299 (allocate_vectorlike): Check for ptrdiff_t overflow.
300 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
301 when a (possibly-narrower) signed value would do just as well.
302 We prefer using signed arithmetic, to avoid comparison confusion.
303
304 * alloc.c: Catch some string size overflows that we were missing.
305 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
306 for convenience in STRING_BYTES_MAX.
307 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
308 The definition here is exact; the one in lisp.h was approximate.
309 (allocate_string_data): Check for string overflow. This catches
310 some instances we weren't catching before. Also, it catches
311 size_t overflow on (unusual) hosts where SIZE_MAX <= min
312 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
313 and ptrdiff_t and EMACS_INT are both 64 bits.
314
315 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
316 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
317 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
318
319 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
320
321 * alloc.c (Fmake_string): Check for out-of-range init.
322
323 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
324
325 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
326
327 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
328
329 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
330 xg_get_default_scrollbar_width.
331
332 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
333 (int_gtk_range_get_value): Move to the scroll bar part of the file.
334 (style_changed_cb): Call update_theme_scrollbar_width and call
335 x_set_scroll_bar_default_width and xg_frame_set_char_size for
336 all frames (Bug#8505).
337 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
338 Call gtk_window_set_resizable if HAVE_GTK3.
339 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
340 and height if HAVE_GTK3 (Bug#8505).
341 (scroll_bar_width_for_theme): New variable.
342 (update_theme_scrollbar_width): New function.
343 (xg_get_default_scrollbar_width): Move code to
344 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
345 (xg_initialize): Call update_theme_scrollbar_width.
346
347 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
348
349 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
350
351 2011-06-12 Martin Rudalics <rudalics@gmx.at>
352
353 * frame.c (make_frame): Call other_buffer_safely instead of
354 other_buffer.
355
356 * window.c (temp_output_buffer_show): Call display_buffer with
357 second argument Vtemp_buffer_show_specifiers and reset latter
358 immediately after the call.
359 (Vtemp_buffer_show_specifiers): New variable.
360 (auto_window_vscroll_p, next_screen_context_lines)
361 (Vscroll_preserve_screen_position): Remove leading asterisks from
362 doc-strings.
363
364 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
365
366 Fix minor problems found by GCC 4.6.0 static checking.
367 * buffer.c (Qclone_number): Remove for now, as it's unused.
368 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
369 (record_buffer): Remove unused local.
370 * frame.c (other_visible_frames, frame_buffer_list): Now static.
371 (set_frame_buffer_list): Remove; unused.
372 * frame.h (other_visible_frames): Remove decl.
373 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
374 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
375 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
376 if HAVE_GPM.
377 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
378 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
379 Define only if HAVE_GPM.
380 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
381 (update_hints_inhibit): Remove; never set. All uses removed.
382 * widgetprv.h (emacsFrameClassRec): Remove decl.
383 * window.c (delete_deletable_window): Now returns void, since it
384 wasn't returning anything.
385 (compare_window_configurations): Remove unused locals.
386 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
387 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
388 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
389 the same widths as pointers. This follows up on the 2011-05-06 patch.
390 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
391 * xterm.h: Likewise.
392 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
393
394 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
395
396 * makefile.w32-in: Update dependencies.
397 (LISP_H): Add lib/intprops.h.
398
399 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
400
401 * image.c (gif_load): Add animation frame delay to the metadata.
402 (syms_of_image): Use DEFSYM. New symbol `delay'.
403
404 2011-06-11 Martin Rudalics <rudalics@gmx.at>
405
406 * window.c (delete_deletable_window): Re-add.
407 (Fset_window_configuration): Rewrite to handle dead buffers and
408 consequently deletable windows.
409 (window_tree, Fwindow_tree): Remove. Supply functionality in
410 window.el.
411 (compare_window_configurations): Simplify code.
412
413 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
414
415 * image.c (imagemagick_load_image): Fix type mismatch.
416 (Fimagemagick_types): Likewise.
417
418 * window.h (replace_buffer_in_windows): Declare.
419
420 2011-06-11 Martin Rudalics <rudalics@gmx.at>
421
422 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
423 Qclone_number. Remove external declaration of Qdelete_window.
424 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
425 code.
426 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
427 Qbuffer_list_update_hook if allowed.
428 (Fother_buffer): Rewrite doc-string. Major rewrite for new
429 buffer list implementation.
430 (other_buffer_safely): New function.
431 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
432 calls to replace_buffer_in_windows and
433 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook

883 (bidi_level_of_next_char, bidi_move_to_visually_next):
884 Support character positions inside a run of characters covered by a
885 display string.
886 (bidi_paragraph_init, bidi_resolve_explicit_1)
887 (bidi_level_of_next_char): Call bidi_fetch_char and
888 bidi_fetch_char_advance instead of FETCH_CHAR and
889 FETCH_CHAR_ADVANCE.
890 (bidi_init_it): Initialize new members.
891 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
892 definitions.
893 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
894 instead of using explicit *_CHAR codes.
895 (bidi_resolve_explicit, bidi_resolve_weak):
896 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
897 bidirectional text is supported only in multibyte buffers.
898 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
899 it to initialize the frame_window_p member of struct bidi_it.
900 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
901 (bidi_resolve_explicit, bidi_resolve_weak)
902 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
903 bidi_it->nchars is non-positive.
904 (bidi_level_of_next_char): Don't try to lookup the cache for the
905 next/previous character if nothing is cached there yet, or if we
906 were just reseat()'ed to a new position.
907
908 * xdisp.c (set_cursor_from_row): Set start and stop points
909 according to the row's direction when priming the loop that looks
910 for the glyph on which to display cursor.
911 (single_display_spec_intangible_p): Function deleted.
912 (display_prop_intangible_p): Reimplement to call
913 handle_display_spec instead of single_display_spec_intangible_p.
914 Accept 3 additional arguments needed by handle_display_spec.
915 This fixes incorrect cursor motion across display property with complex
916 values: lists, `(when COND...)' forms, etc.
917 (single_display_spec_string_p): Support property values that are
918 lists with the argument STRING its top-level element.
919 (display_prop_string_p): Fix the condition for processing a
920 property that is a list to be consistent with handle_display_spec.
921 (handle_display_spec): New function, refactored from the
922 last portion of handle_display_prop.
923 (compute_display_string_pos): Accept additional argument
924 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
925 value of a `display' property is a "replacing spec".
926 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
927 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
928 the display property, but just return a value indicating whether
929 the display property will replace the characters it covers.
930 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
931 frame_window_p members of struct bidi_it.
932 (compute_display_string_pos, compute_display_string_end):
933 New functions.
934 (push_it): Accept second argument POSITION, where pop_it should
935 jump to continue iteration.
936 (reseat_1): Initialize bidi_it.disp_pos.
937
938 * keyboard.c (adjust_point_for_property): Adjust the call to
939 display_prop_intangible_p to its new signature.
940
941 * dispextern.h (struct bidi_it): New member frame_window_p.
942 (bidi_init_it): Update prototypes.
943 (display_prop_intangible_p): Update prototype.
944 (compute_display_string_pos, compute_display_string_end):
945 Declare prototypes.
946 (struct bidi_it): New members nchars and disp_pos. ch_len is now
947 EMACS_INT.

949 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
950
951 Malloc failure behavior now depends on size of allocation.
952 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
953 * lisp.h: Change signatures accordingly.
954 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
955 All callers changed. (Bug#8762)
956
957 * gnutls.c: Use Emacs's memory allocators.
958 Without this change, the gnutls library would invoke malloc etc.
959 directly, which causes problems on non-SYNC_INPUT hosts, and which
960 runs afoul of improving memory_full behavior. (Bug#8761)
961 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
962 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
963 xfree instead of the default malloc, realloc, free.
964 (Fgnutls_boot): No need to check for memory allocation failure,
965 since xmalloc does that for us.
966
967 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
968 * category.c (hash_get_category_set):
969 * ccl.c (ccl_driver):
970 * charset.c (Fdefine_charset_internal):
971 * charset.h (struct charset.hash_index):

980 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
981 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
982 (Fsxhash, Fgethash, Fputhash, Fmaphash):
983 * image.c (make_image, search_image_cache, lookup_image)
984 (xpm_put_color_table_h):
985 * lisp.h (struct Lisp_Hash_Table):
986 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
987 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
988 for hashes and hash indexes, instead of 'unsigned' and 'int'.
989 * alloc.c (allocate_vectorlike):
990 Check for overflow in vector size calculations.
991 * ccl.c (ccl_driver):
992 Check for overflow when converting EMACS_INT to int.
993 * fns.c, image.c: Remove unnecessary static decls that would otherwise
994 need to be updated by these changes.
995 * fns.c (make_hash_table, maybe_resize_hash_table):
996 Check for integer overflow with large hash tables.
997 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
998 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
999 (SXHASH_REDUCE): New macro.
1000 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1001 Use it instead of discarding useful hash info with large hash values.
1002 (sxhash_float): New function.
1003 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1004 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1005 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1006 Rewrite to use FIXNUM_BITS, as this simplifies things.
1007 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1008 Adjust signatures to match updated version of code.
1009 (consing_since_gc): Now EMACS_INT, since a single hash table can
1010 use more than INT_MAX bytes.
1011
1012 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1013
1014 Make it possible to build with GCC-4.6+ -O2 -flto.

1017
1018 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1019
1020 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1021 Call minibuffer-inactive-mode.
1022
1023 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1024
1025 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1026 Update dependencies.
1027
1028 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1029
1030 * data.c (init_data): Remove code for UTS, this system is not
1031 supported anymore.
1032
1033 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1034
1035 Don't force ./temacs to start in terminal mode.
1036
1037 * frame.c (make_initial_frame): Initialize faces in all cases, not
1038 only when CANNOT_DUMP is defined.
1039 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1040
1041 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1042
1043 * dispnew.c (add_window_display_history): Use const for the string
1044 pointer. Remove declaration, not needed.
1045
1046 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1047
1048 Use 'inline', not 'INLINE'.
1049 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1050 * alloc.c, fontset.c (INLINE): Remove.
1051 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1052 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1053 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1054 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1055 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1056
1057 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1058
1059 Make it possible to run ./temacs.
1060
1061 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1062 syms_of_callproc does the same thing. Remove test for
1063 "initialized", do it in the caller.
1064 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1065
1066 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1067
1068 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1069 (read_minibuf): Use get_minibuffer.
1070 (syms_of_minibuf): Use DEFSYM.
1071 (Qmetadata): New var.
1072 * data.c (Qbuffer): Don't make it static.
1073 (syms_of_data): Use DEFSYM.
1074
1075 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1076
1077 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1078 (CCL_CODE_MIN): New macro.
1079
1080 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1081
1082 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1083
1084 * eval.c (Qdebug): Now static.
1085 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1086 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1087 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1088
1089 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1090
1091 * image.c: Various fixes to ImageMagick code comments.
1092 (Fimagemagick_types): Doc fix.
1093
1094 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1095
1096 Minor fixes prompted by GCC 4.6.0 warnings.
1097
1098 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1099
1100 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1101 (x_clipboard_manager_save_all): Move extern decl to ...
1102 * xterm.h: ... here, so that it can be checked for consistency.
1103
1104 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1105
1106 * xselect.c (x_clipboard_manager_save_frame)
1107 (x_clipboard_manager_save_all): New functions.
1108 (Fx_clipboard_manager_save): Lisp function deleted.
1109
1110 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1111 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1112
1113 * xterm.h: Update prototype.
1114
1115 2011-05-28 William Xu <william.xwl@gmail.com>
1116
1117 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1118 exiting (Bug#8239).
1119
1120 2011-05-28 Jim Meyering <meyering@redhat.com>
1121
1122 Avoid a sign-extension bug in crypto_hash_function.
1123 * fns.c (to_uchar): Define.
1124 (crypto_hash_function): Use it to convert some newly-signed
1125 variables to unsigned, to avoid sign-extension bugs. For example,
1126 without this change, (md5 "truc") would evaluate to
1127 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1128 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1129 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1130
1131 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1132
1133 Integer overflow fixes.
1134
1135 * dbusbind.c: Serial number integer overflow fixes.
1136 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1137 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1138 to hold a serial number that is too large for a fixnum.
1139 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1140 Check for serial numbers out of range. Decode any serial number
1141 that was so large that it became a float. (Bug#8722)
1142
1143 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1144 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1145 Use XFASTINT rather than XUINT when numbers are nonnegative.
1146 (xd_append_arg, Fdbus_method_return_internal):
1147 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1148 arguments, check that Lisp number is nonnegative, rather than
1149 silently wrapping negative numbers around. (Bug#8722)
1150 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1151 (Bug#8722)
1152
1153 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1154
1155 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1156
1157 ccl: add integer overflow checks
1158 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1159 (IN_INT_RANGE): New macros.
1160 (ccl_driver): Use them to check for integer overflow when
1161 decoding a CCL program. Many of the new checks are whether XINT (x)
1162 fits in int; it doesn't always, on 64-bit hosts. The new version
1163 doesn't catch all possible integer overflows, but it's an
1164 improvement. (Bug#8719)
1165
1166 * alloc.c (make_event_array): Use XINT, not XUINT.
1167 There's no need for unsigned here.
1168
1169 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1170 This follows up to the 2011-05-06 change that substituted uintptr_t
1171 for EMACS_INT. This case wasn't caught back then.
1172
1173 Rework Fformat to avoid integer overflow issues.
1174 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1175 now (part of C89). Include <verify.h>.
1176 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1177 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1178 (Fformat): Avoid the prepass trying to compute sizes; it was only
1179 approximate and thus did not catch overflow reliably. Instead, walk
1180 through the format just once, formatting and computing sizes as we go,
1181 checking for integer overflow at every step, and allocating a larger
1182 buffer as needed. Keep track separately whether the format is
1183 multibyte. Keep only the most-recently calculated precision, rather
1184 than them all. Record whether each argument has been converted to
1185 string. Use EMACS_INT, not int, for byte and char and arg counts.
1186 Support field widths and precisions larger than INT_MAX. Avoid
1187 sprintf's undefined behavior with conversion specifications such as %#d
1188 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1189 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1190 formatting out-of-range floating point numbers with int
1191 formats. (Bug#8668)
1192
1193 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1194
1195 * data.c: Avoid integer truncation in expressions involving floats.
1196 * data.c: Include <intprops.h>.
1197 (arith_driver): When there's an integer overflow in an expression
1198 involving floating point, convert the integers to floating point
1199 so that the resulting value does not suffer from catastrophic
1200 integer truncation. For example, on a 64-bit host (* 4
1201 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1202 Do not rely on undefined behavior after integer overflow.
1203
1204 merge count_size_as_multibyte, parse_str_to_multibyte
1205 * character.c, character.h (count_size_as_multibyte):
1206 Rename from parse_str_to_multibyte; all uses changed.
1207 Check for integer overflow.
1208 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1209 since it's now a duplicate of the other. This is more of
1210 a character than a buffer op, so better that it's in character.c.
1211 * fns.c, print.c: Adjust to above changes.
1212
1213 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1214
1215 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1216
1217 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1218
1219 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1220 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1221 (x_clipboard_manager_save): Now static.
1222 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1223
1224 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1225 (crypto_hash_function): Now static.
1226 Fix pointer signedness problems. Avoid unnecessary initializations.
1227
1228 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1229
1230 * termhooks.h (Vselection_alist): Make it terminal-local.
1231
1232 * terminal.c (create_terminal): Initialize it.
1233
1234 * xselect.c: Support for clipboard managers.
1235 (Vselection_alist): Move to termhooks.h as terminal-local var.
1236 (LOCAL_SELECTION): New macro.
1237 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1238 (symbol_to_x_atom): Remove gratuitous arg.
1239 (x_handle_selection_request, lisp_data_to_selection_data)
1240 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1241 (x_own_selection, x_get_local_selection, x_convert_selection):
1242 New arg, specifying work frame. Use terminal-local Vselection_alist.
1243 (some_frame_on_display): Delete unused function.
1244 (Fx_own_selection_internal, Fx_get_selection_internal)
1245 (Fx_disown_selection_internal, Fx_selection_owner_p)
1246 (Fx_selection_exists_p): New optional frame arg.
1247 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1248 (x_handle_selection_clear): Don't treat other terminals with the
1249 same keyboard specially. Use the terminal-local Vselection_alist.
1250 (x_clear_frame_selections): Use Frun_hook_with_args.
1251
1252 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1253
1254 * xterm.h: Add support for those atoms.
1255
1256 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1257
1258 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1259 (converted_selections, conversion_fail_tag): New global variables.
1260 (x_selection_request_lisp_error): Free the above.
1261 (x_get_local_selection): Remove unnecessary code.
1262 (x_reply_selection_request): Args changed; handle arbitrary array
1263 of converted selections stored in converted_selections.
1264 Separate the XChangeProperty and SelectionNotify steps.
1265 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1266 (x_convert_selection): New function.
1267 (x_handle_selection_event): Simplify.
1268 (x_get_foreign_selection): Don't ignore incoming requests while
1269 waiting for an answer; this will fail when we implement
1270 SAVE_TARGETS, and seems unnecessary anyway.
1271 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1272 (Vx_sent_selection_functions): Doc fix.
1273
1274 2011-05-26 Leo Liu <sdl.web@gmail.com>
1275
1276 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1277
1278 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1279
1280 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1281
1282 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1283 for fringe update if it has periodic bitmap.
1284 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1285 and fringe_bitmap_periodic_p.
1286
1287 * fringe.c (get_fringe_bitmap_data): New function.
1288 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1289 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1290 row. Mark glyph row for fringe update if periodicity changed.
1291
1292 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1293 for fringe update unless it has periodic bitmap.
1294
1295 2011-05-25 Kenichi Handa <handa@m17n.org>
1296
1297 * xdisp.c (get_next_display_element): Set correct it->face_id for
1298 a static composition.
1299
1300 2011-05-24 Leo Liu <sdl.web@gmail.com>
1301
1302 * deps.mk (fns.o):
1303 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1304
1305 * fns.c (crypto_hash_function, Fsha1): New function.
1306 (Fmd5): Use crypto_hash_function.
1307 (syms_of_fns): Add Ssha1.
1308
1309 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1310
1311 * gnutls.c: Remove unused macros.
1312 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1313 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1314 Remove macros that are defined and never used.
1315 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1316
1317 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1318
1319 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1320 (Fx_get_selection_internal): Minor cleanup.
1321 (Fx_own_selection_internal): Rename arguments for consistency with
1322 select.el.
1323
1324 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1325
1326 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1327
1328 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1329
1330 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1331
1332 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1333
1334 * dispnew.c (scrolling_window): Don't exclude the case that the
1335 last enabled row in the desired matrix touches the bottom boundary.
1336
1337 2011-05-21 Glenn Morris <rgm@gnu.org>
1338
1339 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1340 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1341 and add some more files.
1342
1343 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1344
1345 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1346 report_file_error introduced by the change from 2011-05-07.
1347
1348 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1349
1350 * systime.h (Time): Define only if emacs is defined.
1351 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1352 where the include path doesn't have X11/X.h by default. See
1353 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1354
1355 2011-05-20 Kenichi Handa <handa@m17n.org>
1356
1357 * composite.c (find_automatic_composition): Fix previous change.
1358
1359 2011-05-20 Glenn Morris <rgm@gnu.org>
1360
1361 * lisp.mk: New file, split from Makefile.in.
1362 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1363 (shortlisp): Remove.
1364 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1365
1366 2011-05-19 Glenn Morris <rgm@gnu.org>
1367
1368 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1369 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1370 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1371 (lisp): Set the order to that of loadup.el.
1372 (shortlisp): Make it a copy of $lisp.
1373 (SOME_MACHINE_LISP): Remove.
1374 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1375 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1376
1377 2011-05-18 Kenichi Handa <handa@m17n.org>
1378
1379 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1380 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1381 (find_automatic_composition): Mostly rewrite for efficiency.
1382
1383 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1384
1385 * makefile.w32-in: Update dependencies.
1386
1387 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1388
1389 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1390 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1391
1392 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1393
1394 Fix some integer overflow issues, such as string length overflow.
1395
1396 * insdel.c (count_size_as_multibyte): Check for string overflow.
1397
1398 * character.c (lisp_string_width): Check for string overflow.
1399 Use EMACS_INT, not int, for string indexes and lengths; in
1400 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1401 the resulting string length overflows an EMACS_INT; instead,
1402 report a string overflow if no precision given. When checking for
1403 precision exhaustion, use a check that cannot possibly have
1404 integer overflow. (Bug#8675)
1405 * character.h (lisp_string_width): Adjust to new signature.
1406
1407 * alloc.c (string_overflow): New function.
1408 (Fmake_string): Use it. This doesn't change behavior, but saves
1409 a few bytes and will simplify future changes.
1410 * character.c (string_escape_byte8): Likewise.
1411 * lisp.h (string_overflow): New decl.
1412
1413 Fixups, following up to the user-interface timestamp change.
1414 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1415 for UI timestamps, instead of unsigned long.
1416 * msdos.c (mouse_get_pos): Likewise.
1417 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1418 * w32gui.h (Time): Define by including "systime.h" rather than by
1419 declaring it ourselves. (Bug#8664)
1420
1421 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1422 * image.c (clear_image_cache): Likewise.
1423
1424 * term.c (term_mouse_position): Don't assume time_t wraparound.
1425
1426 Be more systematic about user-interface timestamps.
1427 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1428 and sometimes 'EMACS_UINT', to represent these timestamps.
1429 This change causes it to use 'Time' uniformly, as that's what X uses.
1430 This makes the code easier to follow, and makes it easier to catch
1431 integer overflow bugs such as Bug#8664.
1432 * frame.c (Fmouse_position, Fmouse_pixel_position):
1433 Use Time, not unsigned long, for user-interface timestamps.
1434 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1435 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1436 * keyboard.h (last_event_timestamp): Likewise.
1437 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1438 * menu.h (xmenu_show): Likewise.
1439 * term.c (term_mouse_position): Likewise.
1440 * termhooks.h (struct input_event.timestamp): Likewise.
1441 (struct terminal.mouse_position_hook): Likewise.
1442 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1443 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1444 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1445 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1446 what it was before.
1447 * menu.h, termhooks.h: Include "systime.h", for Time.
1448
1449 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1450 Don't assume that the difference between two unsigned long values
1451 can fit into an integer. At this point, we know button_down_time
1452 <= event->timestamp, so the difference must be nonnegative, so
1453 there's no need to cast the result if double-click-time is
1454 nonnegative, as it should be; check that it's nonnegative, just in
1455 case. This bug is triggered when events are more than 2**31 ms
1456 apart (about 25 days). (Bug#8664)
1457
1458 * xselect.c (last_event_timestamp): Remove duplicate decl.
1459 (x_own_selection): Remove needless cast to unsigned long.
1460
1461 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1462 that always fit in int. Use a sentinel instead of a counter, to
1463 avoid a temp and to allay GCC's concerns about possible int overflow.
1464 * frame.h (struct frame): Use int for menu_bar_items_used
1465 instead of EMACS_INT, since it always fits in int.
1466
1467 * menu.c (grow_menu_items): Check for int overflow.
1468
1469 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1470
1471 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1472 Before, the code was not consistent. These values cannot exceed
1473 2**31 - 1 so there's no need to make them unsigned.
1474 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1475 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1476 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1477 as modifiers.
1478 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1479
1480 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1481 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1482 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1483 presumably because the widths might not match.
1484
1485 * window.c (size_window): Avoid needless test at loop start.
1486
1487 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1488
1489 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1490
1491 2011-05-12 Drew Adams <drew.adams@oracle.com>
1492
1493 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1494
1495 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1496
1497 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1498 `width' to `bar_area_x' and `bar_area_width', respectively.
1499 (x_scroll_run): Take account of fringe background extension.
1500
1501 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1502 Rename local vars `left' and `width' to `bar_area_x' and
1503 `bar_area_width', respectively.
1504 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1505 background extension.
1506
1507 2011-05-10 Jim Meyering <meyering@redhat.com>
1508
1509 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1510
1511 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1512
1513 * image.c (Finit_image_library): Return t for built-in image types,
1514 like pbm and xbm. (Bug#8640)
1515
1516 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1517
1518 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1519
1520 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1521
1522 * w32console.c (Fset_screen_color): Doc fix.
1523 (Fget_screen_color): New function.
1524 (syms_of_ntterm): Defsubr it.
1525
1526 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1527 unlink the temporary file if Fcall_process didn't create it in the
1528 first place.
1529 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1530 child process will be redirected to a file specified with `:file'.
1531 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1532 cue to call_process_cleanup not to close that handle.
1533
1534 2011-05-07 Ben Key <bkey76@gmail.com>
1535
1536 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1537 one of two shell specific rules, either bootstrap-temacs-CMD or
1538 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1539 to the previous implementation of the bootstrap-temacs rule.
1540 The bootstrap-temacs-CMD rule is similar to the previous
1541 implementation of the bootstrap-temacs rule except that it
1542 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1543 variable.
1544
1545 These changes, along with some changes to nt/configure.bat,
1546 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1547 earlier fix to add support for --cflags and --ldflags options
1548 that include quotes so that it works whether make uses cmd or
1549 sh as the shell.
1550
1551 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1552
1553 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1554 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1555 is a constant.
1556 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1557 a string. Handle both cases.
1558 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1559 (Fdbus_register_method): Use Qinvalid_function.
1560
1561 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1562
1563 * makefile.w32-in: Update dependencies.
1564 (LISP_H): Add inttypes.h and stdin.h.
1565 (PROCESS_H): Add unistd.h.
1566
1567 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1568
1569 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1570 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1571
1572 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1573
1574 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1575
1576 * term.c (vfatal): Remove stray call to va_end.
1577 It's not needed and the C Standard doesn't allow it here anyway.
1578
1579 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1580 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1581
1582 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1583 bytes.
1584
1585 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1586
1587 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1588
1589 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1590
1591 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1592
1593 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1594
1595 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1596 * charset.c (Fdefine_charset_internal): Don't initialize
1597 charset.code_space[15]. The value was garbage, on hosts with
1598 32-bit int (Bug#8600).
1599
1600 * lread.c (read_integer): Be more consistent with string-to-number.
1601 Use string_to_number to do the actual conversion; this avoids
1602 rounding errors and fixes some other screwups. Without this fix,
1603 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1604 (digit_to_number): Move earlier, for benefit of read_integer.
1605 Return -1 if the digit is out of range for the base, -2 if it is
1606 not a digit in any supported base. (Bug#8602)
1607
1608 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1609
1610 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1611 to match comment at start of function. This also removes a
1612 GCC warning about overflow in a 32+64-bit port.
1613
1614 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1615
1616 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1617 Reported by Stefan Monnier in
1618 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1619 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1620 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1621
1622 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1623 (EMACS_UINTPTR): Likewise, with uintptr_t.
1624
1625 * lisp.h: Prefer 64-bit EMACS_INT if available.
1626 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1627 on 32-bit hosts that have 64-bit int, so that they can access
1628 large files.
1629 However, temporarily disable this change unless the temporary
1630 symbol WIDE_EMACS_INT is defined.
1631
1632 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1633
1634 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1635 This removes an assumption that EMACS_INT and long are the same
1636 width as pointers. The assumption is true for Emacs porting targets
1637 now, but we want to make other targets possible.
1638 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1639 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1640 In the rest of the code, change types of integers that hold casted
1641 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1642 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1643 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1644 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1645 No need to cast type when ORing.
1646 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1647 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1648 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1649 assume EMACS_INT is the same width as char *.
1650 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1651 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1652 Remove no-longer-needed casts.
1653 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1654 (xg_tool_bar_help_callback, xg_make_tool_item):
1655 Use EMACS_INTPTR to hold an integer
1656 that will be cast to void *; this can avoid a GCC warning
1657 if EMACS_INT is not the same width as void *.
1658 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1659 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1660 (current_message_1, set_message_1):
1661 Use a local to convert to proper width without a cast.
1662 * xmenu.c (dialog_selection_callback): Likewise.
1663
1664 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1665 Also, don't assume VALBITS / RAND_BITS is less than 5,
1666 and don't rely on undefined behavior when shifting a 1 left into
1667 the sign bit.
1668 * lisp.h (get_random): Change signature to match.
1669
1670 * lread.c (hash_string): Use size_t, not int, for hash computation.
1671 Normally we prefer signed values; but hashing is special, because
1672 it's better to use unsigned division on hash table sizes so that
1673 the remainder is nonnegative. Also, size_t is the natural width
1674 for hashing into memory. The previous code used 'int', which doesn't
1675 retain enough info to hash well into very large tables.
1676 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1677
1678 * dbusbind.c: Don't possibly lose pointer info when converting.
1679 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1680 Use XPNTR rather than XHASH, so that the high-order bits of
1681 the pointer aren't lost when converting through void *.
1682
1683 * eval.c (Fautoload): Don't double-shift a pointer.
1684
1685 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1686
1687 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1688
1689 * gnutls.c (DEF_GNUTLS_FN):
1690 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1691
1692 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1693
1694 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end

1850 simple variables to record original value of point. (Bug#7952)
1851

1867 (command_loop_1): Run `delayed-warnings-hook'
1868 if Vdelayed_warnings_list is non-nil.

1891
1892 Improve `doprnt' and its usage. (Bug#8545)
1893 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
1894 `format_end'. Remove support for %l as a conversion specifier.
1895 Don't use xrealloc. Improve diagnostics when the %l size modifier
1896 is used. Update the commentary.
1897
1898 * eval.c (verror): Simplify calculation of size_t.
1899
1900 * coding.c (Ffind_operation_coding_system): Fix diagnostic error

1906 change.
1907
1908 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1909
1910 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
1911 This makes this file independent of the recent pseudovector change.
1912
1913 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
1914
1915 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
1916
1917 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
1918 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
1919 Remove unused local.
1920 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
1921
1922 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
1923 GCC 4.6.0 optimizes based on type-based alias analysis.
1924 For example, if b is of type struct buffer * and v of type struct
1925 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
1926 != &v->size, and therefore "v->size = 1; b->size = 2; return
1927 v->size;" must therefore return 1. This assumption is incorrect
1928 for Emacs, since it type-puns struct Lisp_Vector * with many other
1929 types. To fix this problem, this patch adds a new type struct
1930 vectorlike_header that documents the constraints on layout of vectors
1931 and pseudovectors, and helps optimizing compilers not get fooled
1932 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
1933 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
1934 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
1935 the size member.
1936 (XSETPVECTYPE): Rewrite in terms of new macro.
1937 (XSETPVECTYPESIZE): New macro, specifying both type and size.
1938 This is a bit clearer, and further avoids the possibility of
1939 undesirable aliasing.
1940 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
1941 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
1942 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
1943 since Lisp_Subr is a special case (no "next" field).
1944 (ASIZE): Now uses header.size rather than size.
1945 All previous uses of XVECTOR (foo)->size replaced to use this macro,
1946 to avoid the hassle of writing XVECTOR (foo)->header.size.
1947 (struct vectorlike_header): New type.
1948 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
1949 object, to help avoid aliasing.
1950 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
1951 (SUBRP): Likewise, since Lisp_Subr is a special case.
1952 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
1953 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
1954 (struct Lisp_Hash_Table): Combine first two members into a single
1955 struct vectorlike_header member. All uses of "size" and "next" members
1956 changed to be "header.size" and "header.next".
1957 * buffer.h (struct buffer): Likewise.
1958 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
1959 * frame.h (struct frame): Likewise.
1960 * process.h (struct Lisp_Process): Likewise.
1961 * termhooks.h (struct terminal): Likewise.
1962 * window.c (struct save_window_data, struct saved_window): Likewise.
1963 * window.h (struct window): Likewise.
1964 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
1965 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
1966 * buffer.c (init_buffer_once): Likewise.
1967 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
1968 special case.
1969 * process.c (Fformat_network_address): Use local var for size,
1970 for brevity.
1971
1972 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
1973
1974 Make the Lisp reader and string-to-float more consistent (Bug#8525)
1975 * data.c (atof): Remove decl; no longer used or needed.
1976 (digit_to_number): Move to lread.c.
1977 (Fstring_to_number): Use new string_to_number function, to be
1978 consistent with how the Lisp reader treats infinities and NaNs.
1979 Do not assume that floating-point numbers represent EMACS_INT
1980 without losing information; this is not true on most 64-bit hosts.
1981 Avoid double-rounding errors, by insisting on integers when
1982 parsing non-base-10 numbers, as the documentation specifies.
1983 * lisp.h (string_to_number): New decl, replacing ...
1984 (isfloat_string): Remove.
1985 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
1986 (read1): Do not accept +. and -. as integers; this
1987 appears to have been a coding error. Similarly, do not accept
1988 strings like +-1e0 as floating point numbers. Do not report
1989 overflow for integer overflows unless the base is not 10 which
1990 means we have no simple and reliable way to continue.
1991 Break out the floating-point parsing into a new
1992 function string_to_number, so that Fstring_to_number parses
1993 floating point numbers consistently with the Lisp reader.
1994 (digit_to_number): Move here from data.c. Make it static inline.
1995 (E_CHAR, EXP_INT): Remove, replacing with ...
1996 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
1997 (string_to_number): New function, replacing isfloat_string.
1998 This function checks for valid syntax and produces the resulting
1999 Lisp float number too. Rework it so that string-to-number
2000 no longer mishandles examples like "1.0e+". Use strtoumax,
2001 so that overflow for non-base-10 numbers is reported only when
2002 there's no portable and simple way to convert to floating point.
2003
2004 * textprop.c (set_text_properties_1): Rewrite for clarity,
2005 and to avoid GCC warning about integer overflow.
2006
2007 * intervals.h (struct interval): Use EMACS_INT for members
2008 where EMACS_UINT might cause problems. See
2009 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2010 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2011 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2012 All uses changed.
2013 (offset_intervals): Tell GCC not to worry about length overflow
2014 when negating a negative length.
2015
2016 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2017 (overrun_check_free): Likewise.
2018
2019 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2020 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2021 word size.
2022
2023 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2024 (gnutls_make_error): Rename local to avoid shadowing.
2025 (gnutls_emacs_global_deinit): ifdef out; not used.
2026 (Fgnutls_boot): Use const for pointer to readonly storage.
2027 Comment out unused local. Fix pointer signedness problems.
2028
2029 * lread.c (openp): Don't stuff size_t into an 'int'.
2030 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2031 about possible signed overflow.
2032
2033 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2034 (GDK_KEY_g): Don't define if already defined.
2035 (xg_prepare_tooltip): Avoid pointer signedness problem.
2036 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2037
2038 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2039 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2040
2041 * xfns.c (Fx_window_property): Simplify a bit,
2042 to make a bit faster and to avoid GCC 4.6.0 warning.
2043 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2044
2045 * fns.c (internal_equal): Don't assume size_t fits in int.
2046
2047 * alloc.c (compact_small_strings): Tighten assertion a little.
2048
2049 Replace pEd with more-general pI, and fix some printf arg casts.
2050 * lisp.h (pI): New macro, generalizing old pEd macro to other
2051 conversion specifiers. For example, use "...%"pI"d..." rather
2052 than "...%"pEd"...".
2053 (pEd): Remove. All uses replaced with similar uses of pI.
2054 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2055 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2056 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2057 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2058 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2059 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2060 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2061 64-bit hosts.
2062 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2063 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2064 * print.c (safe_debug_print, print_object): Likewise.
2065 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2066 to int.
2067 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2068 avoiding the 0 flag, which is not portable.
2069 * process.c (Fmake_network_process): Use pI to avoid cast.
2070 * region-cache.c (pp_cache): Likewise.
2071 * xdisp.c (decode_mode_spec): Likewise.
2072 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2073 behavior on 64-bit hosts with printf arg.
2074 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2075 (x_stop_queuing_selection_requests): Likewise.
2076 (x_get_window_property): Don't truncate byte count to an 'int'
2077 when tracing.
2078
2079 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2080 here, since it parses constructs like leading '-' and spaces,
2081 which are not wanted; and it overflows with large numbers.
2082 Instead, simply match F[0-9]+, which is what is wanted anyway.
2083
2084 * alloc.c: Remove unportable assumptions about struct layout.
2085 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2086 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2087 (allocate_vectorlike, make_pure_vector): Use the new macros,
2088 plus offsetof, to remove unportable assumptions about struct layout.
2089 These assumptions hold on all porting targets that I know of, but
2090 they are not guaranteed, they're easy to remove, and removing them
2091 makes further changes easier.
2092
2093 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2094 This doesn't fix a bug but makes the code clearer.
2095 (string_overrun_cookie): Now const. Use initializers that
2096 don't formally overflow signed char, to avoid warnings.
2097 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2098 can cause Emacs to crash when string overrun checking is enabled.
2099 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2100 multiple of sizeof (EMACS_INT); it need not be, if
2101 alignof(EMACS_INT) < sizeof (EMACS_INT).
2102 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2103

2136 Improve doprnt and its use in verror. (Bug#8545)
2137 * doprnt.c (doprnt): Document the set of format control sequences
2138 supported by the function. Use SAFE_ALLOCA instead of always
2139 using `alloca'.
2140
2141 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2142 is one byte too soon. Don't use xrealloc; instead xfree and
2143 xmalloc anew.
2144
2145 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2146

2217 changes in globals.h immediately force recompilation.
2218 (TAGS): Depend on $(CURDIR)/m/intel386.h and
2219 $(CURDIR)/s/ms-w32.h.
2220 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.

2234 conversions. Support %l conversion. Don't assume an EMACS_INT
2235 argument for integer conversions and for %c.
2236
2237 * lisp.h (doprnt): Restore prototype.
2238
2239 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

2251
2252 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
2253
2254 * callint.c (Fcall_interactively): When displaying error message
2255 about invalid control letter, pass the character's codepoint, not
2256 a pointer to its multibyte form. Improve display of the character
2257 in octal and display also its hex code.
2258
2259 * character.c (char_string): Use %x to display the (unsigned)
2260 codepoint of an invalid character, to avoid displaying a bogus

2351 it.
2352
2353 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,

2388 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
2389
2390 * bitmaps: Change bitmaps from unsigned char back to the X11
2391 compatible char. Avoid the old compiler warnings about

2445 (bcmp_translate, regcomp, regexec, print_double_string)
2446 (group_in_compile_stack, re_search, re_search_2, regex_compile)
2447 (re_compile_pattern, re_exec): Declare arguments and local

2460
2461 * nsfont.m: Fixed bugs in ns_get_family and
2462 ns_descriptor_to_entity that were caused by using free to
2463 deallocate memory blocks that were allocated by xmalloc (via
2464 xstrdup). This caused Emacs to crash when compiled with
2465 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
2466 --enable-checking=xmallocoverrun). xfree is now used to
2467 deallocate these memory blocks.

2484 (emacs_read, emacs_write): Use it.
2485 * process.c (send_process): Adjust to the new signatures of
2486 emacs_write and emacs_gnutls_write. Do not attempt to store

2511
2512 * font.c (Qopentype): Don't make static (used from w32uniscribe.c).

2915 * keymap.c (Flookup_key): New forward static decl.
2916 (Fcopy_keymap): Now static.
2917 * keymap.h (Flookup_key): Remove decl.
2918 * process.c (Fget_process): New forward static decl.
2919 (Fprocess_datagram_address): Mark as internal.
2920 * syntax.c (Fsyntax_table_p): New forward static decl.
2921 (skip_chars): Remove duplicate decl.
2922 * textprop.c (Fprevious_property_change): New forward static decl.
2923 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
2924 Now internal.
2925 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
2926 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
2927
2928 * editfns.c (Fformat): Remove unreachable code.
2929
2930 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
2931
2932 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
2933 change. (Bug#8496)
2934
2935 2011-04-13 Eli Zaretskii <eliz@gnu.org>
2936
2937 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
2938 when at ZV. (Bug#8487)
2939
2940 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
2941
2942 * charset.c (Fclear_charset_maps): Use xfree instead of free.
2943 (Bug#8437)
2944 * keyboard.c (parse_tool_bar_item): Likewise.
2945 * sound.c (sound_cleanup, alsa_close): Likewise.
2946 * termcap.c (tgetent): Likewise.
2947 * xfns.c (x_default_font_parameter): Likewise.
2948 * xsettings.c (read_and_apply_settings): Likewise.
2949
2950 * alloc.c (overrun_check_malloc, overrun_check_realloc)
2951 (overrun_check_free): Protoize.
2952
2953 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
2954
2955 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
2956 since callers should never pass a negative size.
2957 Change the signature to match that of plain 'read' and 'write'; see
2958 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
2959 * lisp.h: Update prototypes of emacs_write and emacs_read.
2960
2961 2011-04-11 Eli Zaretskii <eliz@gnu.org>
2962
2963 * xdisp.c (redisplay_window): Don't try to determine the character
2964 position of the scroll margin if the window start point w->startp
2965 is outside the buffer's accessible region. (Bug#8468)
2966
2967 2011-04-10 Eli Zaretskii <eliz@gnu.org>
2968
2969 Fix write-region and its subroutines for buffers > 2GB.
2970 * fileio.c (a_write, e_write): Modify declaration of arguments and
2971 local variables to support buffers larger than 2GB.
2972 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
2973
2974 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
2975 argument, local variables, and return value.
2976
2977 * lisp.h: Update prototypes of emacs_write and emacs_read.
2978
2979 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
2980
2981 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
2982
2983 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
2984
2985 Fix more problems found by GCC 4.6.0's static checks.
2986
2987 * xdisp.c (vmessage): Use a better test for character truncation.
2988
2989 * charset.c (load_charset_map): <, not <=, for optimization,
2990 and to avoid potential problems with integer overflow.
2991 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
2992 * casetab.c (set_identity, shuffle): Likewise.
2993 * editfns.c (Fformat): Likewise.
2994 * syntax.c (skip_chars): Likewise.
2995
2996 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
2997 This also lets GCC 4.6.0 generate slightly better loop code.
2998
2999 * callint.c (Fcall_interactively): <, not <=, for optimization.
3000 (Fcall_interactively): Count the number of arguments produced,
3001 not the number of arguments given. This is simpler and lets GCC
3002 4.6.0 generate slightly better code.
3003
3004 * ftfont.c: Distingish more carefully between FcChar8 and char.
3005 The previous code passed unsigned char * to a functions like
3006 strlen and xstrcasecmp that expect char *, which does not
3007 conform to the C standard.
3008 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3009 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3010 char * when the C standard requires it.
3011
3012 * keyboard.c (read_char): Remove unused var.
3013
3014 * eval.c: Port to Windows vsnprintf (Bug#8435).
3015 Include <limits.h>.
3016 (SIZE_MAX): Define if the headers do not.
3017 (verror): Do not give up if vsnprintf returns a negative count.
3018 Instead, grow the buffer. This ports to Windows vsnprintf, which
3019 does not conform to C99. Problem reported by Eli Zaretskii.
3020 Also, simplify the allocation scheme, by avoiding the need for
3021 calling realloc, and removing the ALLOCATED variable.
3022
3023 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3024
3025 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3026 But keep the doprint source code for now, as we might revamp it
3027 and use it again (Bug#8435).
3028 * lisp.h (doprnt): Remove.
3029 * Makefile.in (base_obj): Remove doprnt.o.
3030 * deps.mk (doprnt.o): Remove.
3031
3032 error: Print 32- and 64-bit integers portably (Bug#8435).
3033 Without this change, on typical 64-bit hosts error ("...%d...", N)
3034 was used to print both 32- and 64-bit integers N, which relied on
3035 undefined behavior.
3036 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3037 New macro.
3038 * lisp.h (error, verror): Mark as printf-like functions.
3039 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3040 Report overflow in size calculations when allocating printf buffer.
3041 Do not truncate output string at its first null byte.
3042 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3043 Truncate the output at a character boundary, since vsnprintf does not
3044 do that.
3045 * charset.c (check_iso_charset_parameter): Convert internal
3046 character to string before calling 'error', since %c now has the
3047 printf meaning.
3048 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3049 overflow when computing char to be passed to 'error'. Do not
3050 pass Lisp_Object to 'error'; pass the integer instead.
3051 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3052 formatted with plain %d.
3053
3054 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3055
3056 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3057
3058 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3059
3060 * xterm.c (x_catch_errors): Remove duplicate declaration.
3061
3062 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3063
3064 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3065
3066 2011-04-10 Jim Meyering <meyering@redhat.com>
3067
3068 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3069 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3070 return ssize_t not "int", and use size_t as the buffer length.
3071 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3072 * gnutls.h: Update declarations.
3073 * process.c (read_process_output): Use ssize_t, to match.
3074 (send_process): Likewise.
3075
3076 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3077
3078 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3079
3080 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3081
3082 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3083 Use unsigned char, to match FcChar8 type definition.
3084
3085 * xterm.c (handle_one_xevent):
3086 * xmenu.c (create_and_show_popup_menu):
3087 * xselect.c (x_decline_selection_request)
3088 (x_reply_selection_request): Avoid type-punned deref of X events.
3089
3090 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3091
3092 Fix some uses of `int' instead of EMACS_INT.
3093 * search.c (string_match_1, fast_string_match)
3094 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3095 (scan_buffer, find_next_newline_no_quit)
3096 (find_before_next_newline, search_command, Freplace_match)
3097 (Fmatch_data): Make some `int' variables be EMACS_INT.
3098
3099 * xdisp.c (display_count_lines): 3rd argument and return value now
3100 EMACS_INT. All callers changed.
3101 (pint2hrstr): Last argument is now EMACS_INT.
3102
3103 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3104 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3105 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
3106 (decode_coding_utf_16, decode_coding_emacs_mule)
3107 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
3108 (decode_coding_ccl, decode_coding_charset)
3109 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
3110 (decode_coding_iso_2022, decode_coding_emacs_mule)
3111 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
3112 <char_offset, last_offset>: Declare EMACS_INT.
3113 (encode_coding_utf_8, encode_coding_utf_16)
3114 (encode_coding_emacs_mule, encode_invocation_designation)
3115 (encode_designation_at_bol, encode_coding_iso_2022)
3116 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
3117 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3118 Declare EMACS_INT.
3119 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3120 (encode_invocation_designation): Last argument P_NCHARS is now
3121 EMACS_INT.
3122 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3123 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
3124
3125 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
3126 All users changed.
3127
3128 * ccl.c (Fccl_execute_on_string): Declare some variables
3129 EMACS_INT.
3130
3131 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
3132
3133 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
3134
3135 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
3136
3137 * process.c (Fformat_network_address): Doc fix.
3138
3139 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
3140
3141 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
3142
3143 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3144
3145 * keyboard.c (read_char): Call Lisp function help-form-show,
3146 instead of using internal_with_output_to_temp_buffer.
3147 (Qhelp_form_show): New var.
3148 (syms_of_keyboard): Use DEFSYM macro.
3149
3150 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3151
3152 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3153
3154 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
3155
3156 * process.c (Flist_processes): Remove to Lisp.
3157 (list_processes_1): Delete.
3158
3159 2011-04-06 Eli Zaretskii <eliz@gnu.org>
3160
3161 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
3162
3163 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3164
3165 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3166
3167 Fix more problems found by GCC 4.6.0's static checks.
3168
3169 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3170
3171 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3172
3173 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
3174
3175 * xdisp.c (vmessage): Mark as a printf-like function.
3176
3177 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
3178
3179 * sound.c (sound_warning): Don't crash if arg contains a printf format.
3180
3181 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
3182 printf-like functions.
3183 (tiff_load): Add casts to remove these marks before passing them
3184 to system-supplied API.
3185
3186 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3187
3188 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3189 This avoids several warnings with gcc -Wstrict-overflow.
3190 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3191 directly, rather than having caller test rule sign. This avoids
3192 some unnecessary tests.
3193 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3194 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3195 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3196
3197 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3198 (xfont_open): Avoid unnecessary tests.

3209 by using the new macro.
3210
3211 * textprop.c (set_text_properties_1): Change while to do-while,
3212 since the condition is always true at first.
3213
3214 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3215 (interval_deletion_adjustment): Return unsigned value.
3216 All uses changed.
3217
3218 * process.c (list_processes_1, create_pty, read_process_output):
3219 (exec_sentinel): Remove vars that were set but not used.
3220 (create_pty): Remove unnecessary "volatile"s.
3221 (Fnetwork_interface_info): Avoid possibility of int overflow.
3222 (read_process_output): Do adaptive read buffering even if carryover.
3223 (read_process_output): Simplify nbytes computation if buffered.
3224
3225 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
3226
3227 * syntax.c (scan_words): Remove var that was set but not used.
3228 (update_syntax_table): Use unsigned instead of int.
3229
3230 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
3231 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
3232 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
3233
3234 * print.c (print_error_message): Avoid int overflow.
3235
3236 * font.c (font_list_entities): Redo for clarity,
3237 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3238
3239 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3240 (font_score): Avoid potential overflow in diff calculation.
3241
3242 * fns.c (substring_both): Remove var that is set but not used.
3243 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3244
3245 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3246
3247 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3248 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3249 can always succeed if overflow has undefined behavior.
3250
3251 * search.c (boyer_moore, wordify): Remove vars set but not used.
3252 (wordify): Omit three unnecessary tests.
3253
3254 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3255 All callers changed. This avoids the need for an unused var.
3256
3257 * casefiddle.c (casify_region): Remove var that is set but not used.
3258
3259 * dired.c (file_name_completion): Remove var that is set but not used.
3260
3261 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3262
3263 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3264 (Finsert_file_contents): Remove unnecessary code checking fd.
3265
3266 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3267 Check for integer overflow on size calculations.
3268
3269 * buffer.c (Fprevious_overlay_change): Remove var that is set
3270 but not used.
3271
3272 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3273 Remove vars that are set but not used.
3274 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3275 (timer_check_2): Mark vars as initialized.
3276
3277 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3278
3279 * image.c (lookup_image): Remove var that is set but not used.
3280 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3281
3282 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3283 that are set but not used.
3284
3285 * xfns.c (make_invisible_cursor): Don't return garbage
3286 if XCreateBitmapFromData fails (Bug#8410).
3287
3288 * xselect.c (x_get_local_selection, x_handle_property_notify):
3289 Remove vars that are set but not used.
3290
3291 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

3295 Remove var that is set but not used.
3296 (scroll_bar_windows_size): Now size_t, not int.
3297 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3298 Check for overflow.
3299
3300 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3301 (map_tty_color) [!defined MSDOS]: Likewise.
3302
3303 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3304
3305 * coding.c: Remove vars that are set but not used.
3306 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3307 All callers changed.
3308 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3309 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3310 (decode_coding_charset): Remove vars that are set but not used.
3311
3312 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3313 that is set but not used.
3314
3315 * print.c (print_object): Remove var that is set but not used.
3316
3317 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3318 The gnulib version avoids calling malloc in the usual case,
3319 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3320 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3321 * filelock.c (current_lock_owner): Likewise.
3322 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3323 * sysdep.c: Include allocator.h, careadlinkat.h.
3324 (emacs_no_realloc_allocator): New static constant.
3325 (emacs_readlink): New function.
3326 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
3327 ../lib/careadlinkat.h.
3328
3329 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3330
3331 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3332 first non-nil return value).
3333
3334 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3335
3336 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6

3373
3374 * lread.c (lisp_file_lexically_bound_p): New function.
3375 (Fload): Bind Qlexical_binding.
3376 (readevalloop): Remove `evalfun' arg.
3377 Bind Qinternal_interpreter_environment.
3378 (Feval_buffer): Bind Qlexical_binding.
3379 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3380 Mark as dynamic.
3381 (syms_of_lread): Declare `lexical-binding'.
3382
3383 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3384
3385 * keyboard.c (eval_dyn): New fun.
3386 (menu_item_eval_property): Use it.
3387
3388 * image.c (parse_image_spec): Use Ffunctionp.
3389
3390 * fns.c (concat, mapcar1): Accept byte-code-functions.
3391
3392 * eval.c (Fsetq): Handle lexical vars.
3393 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3394 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3395 (FletX, Flet): Obey lexical binding.
3396 (Fcommandp): Handle closures.
3397 (Feval): New `lexical' arg.
3398 (eval_sub): New function extracted from Feval. Use it almost
3399 everywhere where Feval was used. Look up vars in lexical env.
3400 Handle closures.
3401 (Ffunctionp): Move from subr.el.
3402 (Ffuncall): Handle closures.
3403 (apply_lambda): Remove `eval_flags'.
3404 (funcall_lambda): Handle closures and new byte-code-functions.
3405 (Fspecial_variable_p): New function.
3406 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3407 but without exporting it to Lisp.
3408
3409 * doc.c (Fdocumentation, store_function_docstring):
3410 * data.c (Finteractive_form): Handle closures.
3411
3412 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3413 interactive spec.
3414
3415 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3416 New byte-codes.
3417 (exec_byte_code): New function extracted from Fbyte_code to handle new
3418 calling convention for byte-code-functions. Add new byte-codes.
3419
3420 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3421
3422 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3423
3424 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3425
3426 * xdisp.c (redisplay_internal): Fix prototype.
3427
3428 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3429
3430 * xdisp.c (SCROLL_LIMIT): New macro.
3431 (try_scrolling): Use it when setting scroll_limit.
3432 Limit scrolling to 100 screen lines.
3433 (redisplay_window): Even when falling back on "recentering",
3434 position point in the window according to scroll-conservatively,
3435 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3436
3437 (try_scrolling): When point is above the window, allow searching
3438 as far as scroll_max, or one screenful, to compute vertical
3439 distance from PT to the scroll margin position. This prevents
3440 try_scrolling from unnecessarily failing when
3441 scroll-conservatively is set to a value slightly larger than the
3442 window height. Clean up the case of PT below the margin at bottom
3443 of window: scroll_max can no longer be INT_MAX. When aggressive
3444 scrolling is in use, don't let point enter the opposite scroll
3445 margin as result of the scroll.
3446 (syms_of_xdisp) <scroll-conservatively>: Document the
3447 threshold of 100 lines for never-recentering scrolling.

3455 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3456 (redisplay_internal): Remove parameter `preserve_echo_area',
3457 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3458
3459 * indent.c (Fvertical_motion):
3460 * window.c (window_scroll_pixel_based, Frecenter):
3461 Don't pass `need_y_p' to `move_it_by_lines'.
3462
3463 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3464
3465 * eval.c (struct backtrace): Don't cheat with negative numbers, but do

3469

3475 binding" message (bug#7967).
3476
3477 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3478
3479 Fix more problems found by GCC 4.6.0's static checks.
3480
3481 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3482 Remove unused local var.
3483
3484 * editfns.c (Fmessage_box): Remove unused local var.
3485
3486 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3487 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3488 Omit unused local vars.
3489 * window.c (shrink_windows): Omit unused local var.
3490 * menu.c (digest_single_submenu): Omit unused local var.
3491 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3492 Omit unused local var.
3493

3495 Don't assume string length fits in int.
3496 (keyremap_step, read_key_sequence): Use size_t for sizes.
3497 (read_key_sequence): Don't check last_real_key_start redundantly.
3498
3499 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3500 instead of alloca (Bug#8344).
3501
3502 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3503 (Fbacktrace_frame): Don't assume nframes fits in int.
3504
3505 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3506
3507 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3508 concerns.
3509
3510 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3511
3512 * cm.c (calccost): Turn while-do into do-while, for clarity.
3513
3514 * keyboard.c (syms_of_keyboard): Use the same style as later
3515 in this function when indexing through an array. This also
3516 works around GCC bug 48267.
3517
3518 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3519

3523 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3524
3525 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3526 This avoids undefined behavior on integer overflow, and is a bit
3527 more convenient anyway since it is compared to a size_t variable.
3528
3529 Variadic C functions now count arguments with size_t, not int.
3530 This avoids an unnecessary limitation on 64-bit machines, which
3531 caused (substring ...) to crash on large vectors (Bug#8344).

3540 (funcall_lambda, mark_backtrace): Likewise.
3541 * fns.c (concat): Likewise.
3542 * frame.c (x_set_frame_parameters): Likewise.
3543 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3544 0 if not found, not -1. All callers changed.
3545
3546 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3547 (stack_copy_size): Now size_t, not int.
3548 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

3573 Vcommand_hook_internal.
3574

3746 * insdel.c (signal_before_change):
3747 * frame.c (Fhandle_switch_frame):
3748 * fileio.c (Fdo_auto_save):
3749 * emacs.c (Fkill_emacs):
3750 * editfns.c (save_excursion_restore):
3751 * cmds.c (internal_self_insert):

3753 * buffer.c (Fkill_all_local_variables):
3754 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3755 Use Frun_hooks.
3756 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3757 unconditionnaly since it does the check itself.

3759 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3760
3761 Fix more problems found by GCC 4.5.2's static checks.
3762
3763 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3764 the first time through the loop, since we know p0 < p1 then.
3765 This also avoids a gcc -Wstrict-overflow warning.
3766
3767 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3768 leading to a memory leak, possible in functions like
3769 load_charset_map_from_file that can allocate an unbounded number
3770 of objects (Bug#8318).
3771
3772 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3773 that could (at least in theory) be that large.
3774
3775 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3776 This is less likely to overflow, and avoids undefined behavior if
3777 overflow does occur. All callers changed. Use strtoul to scan
3778 for the unsigned long integer.
3779 (pint2hrstr): Simplify and tune code slightly.
3780 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
3781
3782 * scroll.c (do_scrolling): Work around GCC bug 48228.
3783 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
3784
3785 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
3786 This also avoids a warning with gcc -Wstrict-overflow.
3787 (validate_x_resource_name): Simplify count usage.
3788 This also avoids a warning with gcc -Wstrict-overflow.
3789
3790 * fileio.c (Fcopy_file): Report error if fchown or fchmod
3791 fail (Bug#8306).
3792
3793 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
3794
3795 * process.c (Fmake_network_process): Use socklen_t, not int,
3796 where POSIX says socklen_t is required in portable programs.
3797 This fixes a porting bug on hosts like 64-bit HP-UX, where
3798 socklen_t is wider than int (Bug#8277).
3799 (Fmake_network_process, server_accept_connection):
3800 (wait_reading_process_output, read_process_output):
3801 Likewise.
3802
3803 * process.c: Rename or move locals to avoid shadowing.

3807 (Fmake_network_process): Define label "retry_connect" only if needed.
3808 (Fnetwork_interface_info): Fix pointer signedness.
3809 (process_send_signal): Add cast to avoid pointer signedness problem.
3810 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
3811 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
3812
3813 Make tparam.h and terminfo.c consistent.
3814 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
3815 Include tparam.h instead, since it declares them.
3816 * cm.h (PC): Remove extern decl; tparam.h now does this.
3817 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3818 * terminfo.c: Include tparam.h, to check interfaces.
3819 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3820 (tparam): Adjust signature to match interface in tparam.h;
3821 this removes some undefined behavior. Check that outstring and len
3822 are zero, which they always are with Emacs.
3823 * tparam.h (PC, BC, UP): New extern decls.
3824
3825 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3826 (xftfont_open): Rename locals to avoid shadowing.
3827
3828 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
3829 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
3830 (OTF_TAG_SYM): Omit macro if not needed.

3833 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
3834 Rename locals to avoid shadowing.
3835
3836 * xfont.c (xfont_list_family): Mark var as initialized.
3837
3838 * xml.c (make_dom): Now static.
3839
3840 * composite.c (composition_compute_stop_pos): Rename local to
3841 avoid shadowing.
3842 (composition_reseat_it): Remove unused locals.
3843 (find_automatic_composition, composition_adjust_point): Likewise.
3844 (composition_update_it): Mark var as initialized.
3845 (find_automatic_composition): Mark vars as initialized,
3846 with a FIXME (Bug#8290).
3847
3848 character.h: Rename locals to avoid shadowing.
3849 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
3850 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
3851 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
3852 (BUF_DEC_POS): Be more systematic about renaming local temporaries
3853 to avoid shadowing.
3854
3855 * textprop.c (property_change_between_p): Remove; unused.
3856
3857 * intervals.c (interval_start_pos): Now static.

3862 Rename locals to avoid shadowing.
3863
3864 * sound.c (wav_play, au_play, Fplay_sound_internal):
3865 Fix pointer signedness.
3866 (alsa_choose_format): Remove unused local var.
3867 (wav_play): Initialize a variable to 0, to prevent undefined
3868 behavior (Bug#8278).
3869
3870 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
3871
3872 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
3873
3874 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
3875 clobbering (Bug#8298).
3876 * sysdep.c (sys_subshell): Likewise.
3877 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
3878
3879 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
3880 This should get cleaned up, so that child_setup has the
3881 same signature on all platforms.
3882
3883 * callproc.c (call_process_cleanup): Now static.
3884 (relocate_fd): Rename locals to avoid shadowing.
3885
3886 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
3887
3888 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
3889 not to be necessary, and produces flickering.
3890
3891 2011-03-20 Glenn Morris <rgm@gnu.org>
3892
3893 * config.in: Remove file.
3894
3895 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
3896
3897 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
3898 are now in src/globals.h.
3899 (syms_of_minibuf): Remove spurious & from previous change.
3900
3901 2011-03-20 Leo <sdl.web@gmail.com>
3902
3903 * minibuf.c (completing-read-function): New variable.
3904 (completing-read-default): Rename from completing-read.
3905 (completing-read): Call completing-read-function.
3906
3907 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3908
3909 * xfaces.c (Fx_load_color_file):
3910 Read color file from absolute filename (bug#8250).
3911
3912 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3913
3914 * makefile.w32-in: Update dependencies.
3915
3916 2011-03-17 Eli Zaretskii <eliz@gnu.org>
3917
3918 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
3919
3920 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

3925 (sigchld_handler): Now static.
3926
3927 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
3928 That way, the code declares only the vars that it needs.
3929 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
3930 * s/cygwin.h (PTY_ITERATION): Likewise.
3931 * s/darwin.h (PTY_ITERATION): Likewise.
3932 * s/gnu-linux.h (PTY_ITERATION): Likewise.
3933
3934 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
3935 * process.c (allocate_pty): Don't declare stb unless it's needed.
3936
3937 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
3938 (CONSTANTLIM): Remove; unused.
3939 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
3940 Define only if needed.
3941
3942 * unexelf.c (unexec): Name an expression,
3943 to avoid gcc -Wbad-function-cast warning.
3944 Use a different way to cause a compilation error if anyone uses
3945 n rather than nn, a way that does not involve shadowing.
3946 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
3947
3948 * deps.mk (unexalpha.o): Remove; unused.
3949
3950 New file unexec.h, the (simple) interface for unexec (Bug#8267).
3951 * unexec.h: New file.
3952 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
3953 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
3954 Depend on unexec.h.
3955 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
3956 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
3957 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
3958 Change as necessary to match prototype in unexec.h.
3959
3960 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
3961 shadowing.
3962 (back_comment, skip_chars): Mark vars as initialized.
3963

3969
3970 * print.c (Fredirect_debugging_output): Fix pointer signedess.
3971
3972 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
3973 warning when compiling print.c.
3974
3975 * font.c (font_unparse_fcname): Abort in an "impossible" situation
3976 instead of using an uninitialized var.
3977 (font_sort_entities): Mark var as initialized.
3978
3979 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
3980
3981 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
3982 pointers to constants.

3991 (Ffillarray): Rename locals to avoid shadowing.
3992
3993 * floatfns.c (domain_error2): Define only if needed.

3995
3996 * alloc.c (mark_backtrace): Move decl from here ...
3997 * lisp.h: ... to here, so that it can be checked.
3998
3999 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
4000 (Fdefvar): Rewrite so as not to use empty "else".
4001 (lisp_indirect_variable): Name an expression,
4002 to avoid gcc -Wbad-function-cast warning.
4003 (Fdefvar): Rename locals to avoid shadowing.
4004
4005 * callint.c (quotify_arg, quotify_args): Now static.
4006 (Fcall_interactively): Rename locals to avoid shadowing.
4007 Use const pointer when appropriate.
4008
4009 * lisp.h (get_system_name, get_operating_system_release):
4010 Move decls here, to check interfaces.
4011 * process.c (get_operating_system_release): Move decl to lisp.h.
4012 * xrdb.c (get_system_name): Likewise.
4013 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4014 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4015 some of which prompt warnings from gcc -Wbad-function-cast.
4016 (Fformat_time_string, Fencode_time, Finsert_char):
4017 (Ftranslate_region_internal, Fformat):
4018 Rename or remove local vars to avoid shadowing.
4019 (Ftranslate_region_internal): Mark var as initialized.
4020
4021 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
4022 avoid shadowing.
4023
4024 * lisp.h (eassert): Check that the argument compiles, even if
4025 ENABLE_CHECKING is not defined.
4026
4027 * data.c (Findirect_variable): Name an expression, to avoid
4028 gcc -Wbad-function-cast warning.
4029 (default_value, arithcompare, arith_driver, arith_error): Now static.
4030 (store_symval_forwarding): Rename local to avoid shadowing.
4031 (Fmake_variable_buffer_local, Fmake_local_variable):
4032 Mark variables as initialized.
4033 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
4034
4035 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
4036 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4037 Rename locals to avoid shadowing.
4038 (mark_stack): Move local variables into the #ifdef region where
4039 they're used.
4040 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4041 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4042 needed otherwise.
4043 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4044 (GC_STRING_CHARS): Remove; not used.
4045 (Fmemory_limit): Cast sbrk's returned value to char *.
4046
4047 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4048 avoids undefined behavior in theory.
4049
4050 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4051
4052 Use functions, not macros, for up- and down-casing (Bug#8254).
4053 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4054 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4055 to use the following functions instead of these macros.
4056 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4057 EMACS_INT, since callers assume the returned value fits in int.
4058 (upcase1): Likewise, for UPCASE_TABLE.
4059 (uppercasep, lowercasep, upcase): New static inline functions.
4060 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
4061 the race-condition problem in the old DOWNCASE.
4062
4063 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
4064 Rename locals to avoid shadowing.
4065 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4066 (regex_compile, re_search_2, re_match_2_internal):
4067 Remove unused local vars.
4068 (FREE_VAR): Rewrite so as not to use empty "else",
4069 which gcc can warn about.
4070 (regex_compile, re_match_2_internal): Mark locals as initialized.
4071 (RETALLOC_IF): Define only if needed.
4072 (WORDCHAR_P): Likewise. This one is never needed, but is used
4073 only in a comment talking about a compiler bug, so put inside
4074 the #if 0 of that comment.
4075 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4076 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4077 Remove; unused.
4078
4079 * search.c (boyer_moore): Rename locals to avoid shadowing.
4080 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4081 (PREV_CHAR_BOUNDARY): Likewise.
4082
4083 * search.c (simple_search): Remove unused var.
4084
4085 * dired.c (compile_pattern): Move decl from here ...
4086 * lisp.h: ... to here, so that it can be checked.
4087 (struct re_registers): New forward decl.
4088
4089 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
4090
4091 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
4092 All uses changed.
4093 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
4094 Rename locals to avoid shadowing.
4095 (Fvertical_motion): Mark locals as initialized.
4096
4097 * casefiddle.c (casify_object, casify_region): Now static.
4098 (casify_region): Mark local as initialized.
4099
4100 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4101
4102 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4103 New macros, so that the caller can use some names other than
4104 gcpro1, gcpro2, etc.
4105 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4106 of the new macros.
4107 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4108 argument, for consistency with GCPRO2_VAR, etc: it is now the
4109 prefix of the variable, not the variable itself. All uses
4110 changed.
4111 * dired.c (directory_files_internal, file_name_completion):
4112 Rename locals to avoid shadowing.
4113
4114 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4115 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4116 dired.c's scmp function, had undefined behavior.
4117 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4118 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4119 * buffer.h: ... to here, because these macros use current_buffer,
4120 and the new implementation with inline functions needs to have
4121 current_buffer in scope now, rather than later when the macros
4122 are used.
4123 (downcase, upcase1): New static inline functions.
4124 (DOWNCASE, UPCASE1): Reimplement using these functions.
4125 This avoids undefined behavior in expressions like
4126 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4127 from race conditions in accessing the global variables
4128 case_temp1 and case_temp2.
4129 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4130 * lisp.h (case_temp1, case_temp2): Remove their decls.
4131 * character.h (ASCII_CHAR_P): Move from here ...
4132 * lisp.h: ... to here, so that the inline functions mentioned
4133 above can use them.
4134
4135 * dired.c (directory_files_internal_unwind): Now static.
4136
4137 * fileio.c (file_name_as_directory, directory_file_name):
4138 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4139 Now static.
4140 (file_name_as_directory): Use const pointers when appropriate.
4141 (Fexpand_file_name): Likewise. In particular, newdir might
4142 point at constant storage, so make it a const pointer.
4143 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4144 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4145 signedness issues.
4146 (Fset_file_times, Finsert_file_contents, auto_save_error):
4147 Rename locals to avoid shadowing.
4148
4149 * minibuf.c (choose_minibuf_frame_1): Now static.
4150 (Ftry_completion, Fall_completions): Rename or remove locals
4151 to avoid shadowing.
4152
4153 * marker.c (bytepos_to_charpos): Remove; unused.
4154
4155 * lisp.h (verify_bytepos, count_markers): New decls,
4156 so that gcc does not warn that these functions aren't declared.
4157
4158 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4159 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4160 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4161 (copy_text): Remove unused local var.
4162
4163 * filelock.c (within_one_second): Now static.
4164 (lock_file_1): Rename local to avoid shadowing.
4165
4166 * buffer.c (fix_overlays_before): Mark locals as initialized.
4167 (fix_start_end_in_overlays): Likewise. This function should be
4168 simplified by using pointers-to-pointers, but that's a different
4169 matter.

4573 * term.c, tparam.h: Include it.
4574 * deps.mk (term.o, tparam.o): Depend on tparam.h.

4576 Move these decls to tparam.h, and make them agree with what
4577 is actually in tparam.c. The previous trick of using incompatible
4578 decls in different modules does not conform to the C standard.

4581 Use const pointers where appropriate.
