10 2011-06-21 Leo Liu <sdl.web@gmail.com>
11
12 * deps.mk (fns.o):
13 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14 sha512.h.
15
16 * fns.c (secure_hash): Rename from crypto_hash_function and change
17 the first arg to accept symbols.
18 (Fsecure_hash): New primtive.
19 (syms_of_fns): New symbols.
20
21 2011-06-20 Deniz Dogan <deniz@dogan.se>
22
23 * process.c (Fset_process_buffer): Clarify return value in
24 docstring.
25
26 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
27
28 * dispnew.c (add_window_display_history): Use BVAR.
29
30 * xdisp.c (debug_method_add): Use BVAR.
31 (check_window_end, dump_glyph_matrix, dump_glyph)
32 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
33
34 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
35 Likewise.
36
37 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
38 check till after the cache is created in init_frame_faces.
39
40 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
41
42 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
43
44 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
45
46 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
47 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
48 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
49
50 Improve buffer-overflow checking (Bug#8873).
51 * fileio.c (Finsert_file_contents):
52 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
53 Remove the old (too-loose) buffer overflow checks.
54 They weren't needed, since make_gap checks for buffer overflow.
55 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
56 The old code merely checked for Emacs fixnum overflow, and relied
57 on undefined (wraparound) behavior. The new code avoids undefined
58 behavior, and also checks for ptrdiff_t and/or size_t overflow.
59
60 * editfns.c (Finsert_char): Don't dump core with very negative counts.
61 Tune. Don't use wider integers than needed. Don't use alloca.
62 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
63
64 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
65
66 * insdel.c, lisp.h (buffer_overflow): New function.
67 (insert_from_buffer_1, replace_range, replace_range_2):
68 * insdel.c (make_gap_larger):
69 * editfns.c (Finsert_char):
70 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
71
72 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
73
74 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
75
76 Integer overflow and signedness fixes (Bug#8873).
77
78 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
79 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
80
81 * fileio.c: Don't assume EMACS_INT fits in off_t.
82 (emacs_lseek): New static function.
83 (Finsert_file_contents, Fwrite_region): Use it.
84 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
85
86 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
87
88 * fns.c: Don't overflow int when computing a list length.
89 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
90 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
91 truncation on 64-bit hosts. Check for QUIT every
92 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
93 faster and is responsive enough.
94 (Flength): Report an error instead of overflowing an integer.
95 (Fsafe_length): Return a float if the value is not representable
96 as a fixnum. This shouldn't happen except in contrived situations.
97 (Fnthcdr, Fsort): Don't assume list length fits in int.
98 (Fcopy_sequence): Don't assume vector length fits in int.
99
100 * alloc.c: Check that resized vectors' lengths fit in fixnums.
101 (header_size, word_size): New constants.
102 (allocate_vectorlike): Don't check size overflow here.
103 (allocate_vector): Check it here instead, since this is the only
104 caller of allocate_vectorlike that could cause overflow.
105 Check that the new vector's length is representable as a fixnum.
106
107 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
108 The previous code was bogus. For example, next_almost_prime (32)
109 returned 39, which is undesirable as it is a multiple of 3; and
110 next_almost_prime (24) returned 25, which is a multiple of 5 so
111 why was the code bothering to check for multiples of 7?
112
113 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
114
115 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
116
117 Variadic C functions now count arguments with ptrdiff_t.
118 This partly undoes my 2011-03-30 change, which replaced int with size_t.
119 Back then I didn't know that the Emacs coding style prefers signed int.
120 Also, in the meantime I found a few more instances where arguments
121 were being counted with int, which may truncate counts on 64-bit
122 machines, or EMACS_INT, which may be unnecessarily wide.
123 * lisp.h (struct Lisp_Subr.function.aMANY)
124 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
125 Arg counts are now ptrdiff_t, not size_t.
126 All variadic functions and their callers changed accordingly.
127 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
128 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
129 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
130 * callint.c (Fcall_interactively): Check arg count for overflow,
131 to avoid potential buffer overrun. Use signed char, not 'int',
132 for 'varies' array, so that we needn't bother to check its size
133 calculation for overflow.
134 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
135 * eval.c (apply_lambda):
136 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
137 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
138 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
139
140 * callint.c (Fcall_interactively): Don't use index var as event count.
141
142 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
143 * mem-limits.h (SIZE): Remove; no longer used.
144
145 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
146
147 Remove unnecessary casts.
148 * xterm.c (x_term_init):
149 * xfns.c (x_set_border_pixel):
150 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
151 These aren't needed now that we assume ANSI C.
152
153 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
154 It's more likely to cause problems (due to unsigned overflow)
155 than to cure them.
156
157 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
158
159 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
160
161 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
162
163 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
164
165 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
166
167 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
168
169 GLYPH_CODE_FACE returns EMACS_INT, not int.
170 * dispextern.h (merge_faces):
171 * xfaces.c (merge_faces):
172 * xdisp.c (get_next_display_element, next_element_from_display_vector):
173 Don't assume EMACS_INT fits in int.
174
175 * character.h (CHAR_VALID_P): Remove unused parameter.
176 * fontset.c, lisp.h, xdisp.c: All uses changed.
177
178 * editfns.c (Ftranslate_region_internal): Omit redundant test.
179
180 * fns.c (concat): Minor tuning based on overflow analysis.
181 This doesn't fix any bugs. Use int to hold character, instead
182 of constantly refetching from Emacs object. Use XFASTINT, not
183 XINT, for value known to be a character. Don't bother comparing
184 a single byte to 0400, as it's always less.
185
186 * floatfns.c (Fexpt):
187 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
188
189 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
190 for characters.
191
192 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
193
194 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
195 Without this fix, on a 64-bit host (aset S 0 4294967386) would
196 incorrectly succeed when S was a string, because 4294967386 was
197 truncated before it was used.
198
199 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
200 Otherwise, an out-of-range integer could cause undefined behavior
201 on a 64-bit host.
202
203 * composite.c: Use int, not EMACS_INT, for characters.
204 (fill_gstring_body, composition_compute_stop_pos): Use int, not
205 EMACS_INT, for values that are known to be in character range.
206 This doesn't fix any bugs but is the usual style inside Emacs and
207 may generate better code on 32-bit machines.
208
209 Make sure a 64-bit char is never passed to ENCODE_CHAR.
210 This is for reasons similar to the recent CHAR_STRING fix.
211 * charset.c (Fencode_char): Check that character arg is actually
212 a character. Pass an int to ENCODE_CHAR.
213 * charset.h (ENCODE_CHAR): Verify that the character argument is no
214 wider than 'int', as a compile-time check to prevent future regressions
215 in this area.
216
217 * character.c (char_string): Remove unnecessary casts.
218
219 Make sure a 64-bit char is never passed to CHAR_STRING.
220 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
221 by silently ignoring the top 32 bits, allowing some values
222 that were far too large to be valid characters.
223 * character.h: Include <verify.h>.
224 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
225 arguments are no wider than unsigned, as a compile-time check
226 to prevent future regressions in this area.
227 * data.c (Faset):
228 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
229 (Fsubst_char_in_region):
230 * fns.c (concat):
231 * xdisp.c (decode_mode_spec_coding):
232 Adjust to CHAR_STRING's new requirement.
233 * editfns.c (Finsert_char, Fsubst_char_in_region):
234 * fns.c (concat): Check that character args are actually
235 characters. Without this test, these functions did the wrong
236 thing with wildly out-of-range values on 64-bit hosts.
237
238 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
239 These casts should not be needed on 32-bit hosts, either.
240 * keyboard.c (read_char):
241 * lread.c (Fload): Remove casts to unsigned.
242
243 * lisp.h (UNSIGNED_CMP): New macro.
244 This fixes comparison bugs on 64-bit hosts.
245 (ASCII_CHAR_P): Use it.
246 * casefiddle.c (casify_object):
247 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
248 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
249 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
250 * dispextern.h (FACE_FROM_ID):
251 * keyboard.c (read_char): Use UNSIGNED_CMP.
252
253 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
254 not to EMACS_INT, to avoid GCC warning.
255
256 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
257
258 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
259 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
260 isn't needed on 32-bit machines.
261
262 * buffer.c (Fgenerate_new_buffer_name):
263 Use EMACS_INT for count, not int.
264 (advance_to_char_boundary): Return EMACS_INT, not int.
265
266 * data.c (Qcompiled_function): Now static.
267
268 * window.c (window_body_lines): Now static.
269
270 * image.c (gif_load): Rename local to avoid shadowing.
271
272 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
273 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
274 * alloc.c (make_save_value): Integer argument is now of type
275 ptrdiff_t, not int.
276 (mark_object): Use ptrdiff_t, not int.
277 * lisp.h (pD): New macro.
278 * print.c (print_object): Use it.
279
280 * alloc.c: Use EMACS_INT, not int, to count objects.
281 (total_conses, total_markers, total_symbols, total_vector_size)
282 (total_free_conses, total_free_markers, total_free_symbols)
283 (total_free_floats, total_floats, total_free_intervals)
284 (total_intervals, total_strings, total_free_strings):
285 Now EMACS_INT, not int. All uses changed.
286 (Fgarbage_collect): Compute overall total using a double, so that
287 integer overflow is less likely to be a problem. Check for overflow
288 when converting back to an integer.
289 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
290 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
291 These were 'int' variables that could overflow on 64-bit hosts;
292 they were never used, so remove them instead of repairing them.
293 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
294 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
295 Previously, this ceilinged at INT_MAX, but that doesn't work on
296 64-bit machines.
297 (allocate_pseudovector): Don't use EMACS_INT when int would do.
298
299 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
300 (allocate_vectorlike): Check for ptrdiff_t overflow.
301 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
302 when a (possibly-narrower) signed value would do just as well.
303 We prefer using signed arithmetic, to avoid comparison confusion.
304
305 * alloc.c: Catch some string size overflows that we were missing.
306 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
307 for convenience in STRING_BYTES_MAX.
308 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
309 The definition here is exact; the one in lisp.h was approximate.
310 (allocate_string_data): Check for string overflow. This catches
311 some instances we weren't catching before. Also, it catches
312 size_t overflow on (unusual) hosts where SIZE_MAX <= min
313 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
314 and ptrdiff_t and EMACS_INT are both 64 bits.
315
316 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
317 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
318 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
319
320 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
321
322 * alloc.c (Fmake_string): Check for out-of-range init.
323
324 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
325
326 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
327
328 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
329
330 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
331 xg_get_default_scrollbar_width.
332
333 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
334 (int_gtk_range_get_value): Move to the scroll bar part of the file.
335 (style_changed_cb): Call update_theme_scrollbar_width and call
336 x_set_scroll_bar_default_width and xg_frame_set_char_size for
337 all frames (Bug#8505).
338 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
339 Call gtk_window_set_resizable if HAVE_GTK3.
340 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
341 and height if HAVE_GTK3 (Bug#8505).
342 (scroll_bar_width_for_theme): New variable.
343 (update_theme_scrollbar_width): New function.
344 (xg_get_default_scrollbar_width): Move code to
345 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
346 (xg_initialize): Call update_theme_scrollbar_width.
347
348 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
349
350 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
351
352 2011-06-12 Martin Rudalics <rudalics@gmx.at>
353
354 * frame.c (make_frame): Call other_buffer_safely instead of
355 other_buffer.
356
357 * window.c (temp_output_buffer_show): Call display_buffer with
358 second argument Vtemp_buffer_show_specifiers and reset latter
359 immediately after the call.
360 (Vtemp_buffer_show_specifiers): New variable.
361 (auto_window_vscroll_p, next_screen_context_lines)
362 (Vscroll_preserve_screen_position): Remove leading asterisks from
363 doc-strings.
364
365 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
366
367 Fix minor problems found by GCC 4.6.0 static checking.
368 * buffer.c (Qclone_number): Remove for now, as it's unused.
369 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
370 (record_buffer): Remove unused local.
371 * frame.c (other_visible_frames, frame_buffer_list): Now static.
372 (set_frame_buffer_list): Remove; unused.
373 * frame.h (other_visible_frames): Remove decl.
374 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
375 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
376 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
377 if HAVE_GPM.
378 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
379 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
380 Define only if HAVE_GPM.
381 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
382 (update_hints_inhibit): Remove; never set. All uses removed.
383 * widgetprv.h (emacsFrameClassRec): Remove decl.
384 * window.c (delete_deletable_window): Now returns void, since it
385 wasn't returning anything.
386 (compare_window_configurations): Remove unused locals.
387 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
388 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
389 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
390 the same widths as pointers. This follows up on the 2011-05-06 patch.
391 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
392 * xterm.h: Likewise.
393 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
394
395 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
396
397 * makefile.w32-in: Update dependencies.
398 (LISP_H): Add lib/intprops.h.
399
400 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
401
402 * image.c (gif_load): Add animation frame delay to the metadata.
403 (syms_of_image): Use DEFSYM. New symbol `delay'.
404
405 2011-06-11 Martin Rudalics <rudalics@gmx.at>
406
407 * window.c (delete_deletable_window): Re-add.
408 (Fset_window_configuration): Rewrite to handle dead buffers and
409 consequently deletable windows.
410 (window_tree, Fwindow_tree): Remove. Supply functionality in
411 window.el.
412 (compare_window_configurations): Simplify code.
413
414 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
415
416 * image.c (imagemagick_load_image): Fix type mismatch.
417 (Fimagemagick_types): Likewise.
418
419 * window.h (replace_buffer_in_windows): Declare.
420
421 2011-06-11 Martin Rudalics <rudalics@gmx.at>
422
423 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
424 Qclone_number. Remove external declaration of Qdelete_window.
425 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
426 code.
427 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
428 Qbuffer_list_update_hook if allowed.
429 (Fother_buffer): Rewrite doc-string. Major rewrite for new
430 buffer list implementation.
431 (other_buffer_safely): New function.
432 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
433 calls to replace_buffer_in_windows and
434 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
435 if allowed.
436 (record_buffer): Inhibit quitting and rewrite using quittable
437 functions. Run Qbuffer_list_update_hook if allowed.
438 (Frecord_buffer, Funrecord_buffer): New functions.

887 (bidi_paragraph_init, bidi_resolve_explicit_1)
888 (bidi_level_of_next_char): Call bidi_fetch_char and
889 bidi_fetch_char_advance instead of FETCH_CHAR and
890 FETCH_CHAR_ADVANCE.
891 (bidi_init_it): Initialize new members.
892 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
893 definitions.
894 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
895 instead of using explicit *_CHAR codes.
896 (bidi_resolve_explicit, bidi_resolve_weak):
897 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
898 bidirectional text is supported only in multibyte buffers.
899 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
900 it to initialize the frame_window_p member of struct bidi_it.
901 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
902 (bidi_resolve_explicit, bidi_resolve_weak)
903 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
904 bidi_it->nchars is non-positive.
905 (bidi_level_of_next_char): Don't try to lookup the cache for the
906 next/previous character if nothing is cached there yet, or if we
907 were just reseat()'ed to a new position.
908
909 * xdisp.c (set_cursor_from_row): Set start and stop points
910 according to the row's direction when priming the loop that looks
911 for the glyph on which to display cursor.
912 (single_display_spec_intangible_p): Function deleted.
913 (display_prop_intangible_p): Reimplement to call
914 handle_display_spec instead of single_display_spec_intangible_p.
915 Accept 3 additional arguments needed by handle_display_spec.
916 This fixes incorrect cursor motion across display property with complex
917 values: lists, `(when COND...)' forms, etc.
918 (single_display_spec_string_p): Support property values that are
919 lists with the argument STRING its top-level element.
920 (display_prop_string_p): Fix the condition for processing a
921 property that is a list to be consistent with handle_display_spec.
922 (handle_display_spec): New function, refactored from the
923 last portion of handle_display_prop.
924 (compute_display_string_pos): Accept additional argument
925 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
926 value of a `display' property is a "replacing spec".
927 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
928 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
929 the display property, but just return a value indicating whether
930 the display property will replace the characters it covers.
931 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
932 frame_window_p members of struct bidi_it.
933 (compute_display_string_pos, compute_display_string_end):
934 New functions.
935 (push_it): Accept second argument POSITION, where pop_it should
936 jump to continue iteration.
937 (reseat_1): Initialize bidi_it.disp_pos.
938
939 * keyboard.c (adjust_point_for_property): Adjust the call to
940 display_prop_intangible_p to its new signature.
941
942 * dispextern.h (struct bidi_it): New member frame_window_p.
943 (bidi_init_it): Update prototypes.
944 (display_prop_intangible_p): Update prototype.
945 (compute_display_string_pos, compute_display_string_end):
946 Declare prototypes.
947 (struct bidi_it): New members nchars and disp_pos. ch_len is now
948 EMACS_INT.
949
950 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
951
952 Malloc failure behavior now depends on size of allocation.
953 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
954 * lisp.h: Change signatures accordingly.
955 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
956 All callers changed. (Bug#8762)
957
958 * gnutls.c: Use Emacs's memory allocators.
959 Without this change, the gnutls library would invoke malloc etc.
960 directly, which causes problems on non-SYNC_INPUT hosts, and which
961 runs afoul of improving memory_full behavior. (Bug#8761)
962 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
963 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
964 xfree instead of the default malloc, realloc, free.
965 (Fgnutls_boot): No need to check for memory allocation failure,
966 since xmalloc does that for us.
967
968 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
969 * category.c (hash_get_category_set):
970 * ccl.c (ccl_driver):
971 * charset.c (Fdefine_charset_internal):
972 * charset.h (struct charset.hash_index):

974 (composition_gstring_put_cache):
975 * composite.h (struct composition.hash_index):
976 * dispextern.h (struct image.hash):
977 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
978 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
979 (hashfn_equal, hashfn_user_defined, make_hash_table)
980 (maybe_resize_hash_table, hash_lookup, hash_put)
981 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
982 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
983 (Fsxhash, Fgethash, Fputhash, Fmaphash):
984 * image.c (make_image, search_image_cache, lookup_image)
985 (xpm_put_color_table_h):
986 * lisp.h (struct Lisp_Hash_Table):
987 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
988 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
989 for hashes and hash indexes, instead of 'unsigned' and 'int'.
990 * alloc.c (allocate_vectorlike):
991 Check for overflow in vector size calculations.
992 * ccl.c (ccl_driver):
993 Check for overflow when converting EMACS_INT to int.
994 * fns.c, image.c: Remove unnecessary static decls that would otherwise
995 need to be updated by these changes.
996 * fns.c (make_hash_table, maybe_resize_hash_table):
997 Check for integer overflow with large hash tables.
998 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
999 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1000 (SXHASH_REDUCE): New macro.
1001 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1002 Use it instead of discarding useful hash info with large hash values.
1003 (sxhash_float): New function.
1004 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1005 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1006 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1007 Rewrite to use FIXNUM_BITS, as this simplifies things.
1008 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1009 Adjust signatures to match updated version of code.
1010 (consing_since_gc): Now EMACS_INT, since a single hash table can
1011 use more than INT_MAX bytes.
1012
1013 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1014
1015 Make it possible to build with GCC-4.6+ -O2 -flto.

1018
1019 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1020
1021 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1022 Call minibuffer-inactive-mode.
1023
1024 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1025
1026 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1027 Update dependencies.
1028
1029 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1030
1031 * data.c (init_data): Remove code for UTS, this system is not
1032 supported anymore.
1033
1034 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1035
1036 Don't force ./temacs to start in terminal mode.
1037
1038 * frame.c (make_initial_frame): Initialize faces in all cases, not
1039 only when CANNOT_DUMP is defined.
1040 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1041
1042 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1043
1044 * dispnew.c (add_window_display_history): Use const for the string
1045 pointer. Remove declaration, not needed.
1046
1047 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1048
1049 Use 'inline', not 'INLINE'.
1050 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1051 * alloc.c, fontset.c (INLINE): Remove.
1052 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1053 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1054 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1055 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1056 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1057
1058 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1059
1060 Make it possible to run ./temacs.
1061
1062 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1063 syms_of_callproc does the same thing. Remove test for
1064 "initialized", do it in the caller.
1065 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1066
1067 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1068
1069 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1070 (read_minibuf): Use get_minibuffer.
1071 (syms_of_minibuf): Use DEFSYM.
1072 (Qmetadata): New var.
1073 * data.c (Qbuffer): Don't make it static.
1074 (syms_of_data): Use DEFSYM.
1075
1076 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1077
1078 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1079 (CCL_CODE_MIN): New macro.
1080
1081 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1082
1083 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1084
1085 * eval.c (Qdebug): Now static.
1086 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1087 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1088 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1089
1090 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1091
1092 * image.c: Various fixes to ImageMagick code comments.
1093 (Fimagemagick_types): Doc fix.
1094
1095 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1096
1097 Minor fixes prompted by GCC 4.6.0 warnings.
1098
1099 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1100
1101 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1102 (x_clipboard_manager_save_all): Move extern decl to ...
1103 * xterm.h: ... here, so that it can be checked for consistency.
1104
1105 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1106
1107 * xselect.c (x_clipboard_manager_save_frame)
1108 (x_clipboard_manager_save_all): New functions.
1109 (Fx_clipboard_manager_save): Lisp function deleted.
1110
1111 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1112 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1113
1114 * xterm.h: Update prototype.
1115
1116 2011-05-28 William Xu <william.xwl@gmail.com>
1117
1118 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1119 exiting (Bug#8239).
1120
1121 2011-05-28 Jim Meyering <meyering@redhat.com>
1122
1123 Avoid a sign-extension bug in crypto_hash_function.
1124 * fns.c (to_uchar): Define.
1125 (crypto_hash_function): Use it to convert some newly-signed
1126 variables to unsigned, to avoid sign-extension bugs. For example,
1127 without this change, (md5 "truc") would evaluate to
1128 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1129 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1130 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1131
1132 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1133
1134 Integer overflow fixes.
1135
1136 * dbusbind.c: Serial number integer overflow fixes.
1137 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1138 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1139 to hold a serial number that is too large for a fixnum.
1140 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1141 Check for serial numbers out of range. Decode any serial number
1142 that was so large that it became a float. (Bug#8722)
1143
1144 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1145 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1146 Use XFASTINT rather than XUINT when numbers are nonnegative.
1147 (xd_append_arg, Fdbus_method_return_internal):
1148 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1149 arguments, check that Lisp number is nonnegative, rather than
1150 silently wrapping negative numbers around. (Bug#8722)
1151 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1152 (Bug#8722)
1153
1154 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1155
1156 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1157
1158 ccl: add integer overflow checks
1159 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1160 (IN_INT_RANGE): New macros.
1161 (ccl_driver): Use them to check for integer overflow when
1162 decoding a CCL program. Many of the new checks are whether XINT (x)
1163 fits in int; it doesn't always, on 64-bit hosts. The new version
1164 doesn't catch all possible integer overflows, but it's an
1165 improvement. (Bug#8719)
1166
1167 * alloc.c (make_event_array): Use XINT, not XUINT.
1168 There's no need for unsigned here.
1169
1170 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1171 This follows up to the 2011-05-06 change that substituted uintptr_t
1172 for EMACS_INT. This case wasn't caught back then.
1173
1174 Rework Fformat to avoid integer overflow issues.
1175 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1176 now (part of C89). Include <verify.h>.
1177 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1178 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1179 (Fformat): Avoid the prepass trying to compute sizes; it was only
1180 approximate and thus did not catch overflow reliably. Instead, walk
1181 through the format just once, formatting and computing sizes as we go,
1182 checking for integer overflow at every step, and allocating a larger
1183 buffer as needed. Keep track separately whether the format is
1184 multibyte. Keep only the most-recently calculated precision, rather
1185 than them all. Record whether each argument has been converted to
1186 string. Use EMACS_INT, not int, for byte and char and arg counts.
1187 Support field widths and precisions larger than INT_MAX. Avoid
1188 sprintf's undefined behavior with conversion specifications such as %#d
1189 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1190 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1191 formatting out-of-range floating point numbers with int
1192 formats. (Bug#8668)
1193
1194 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1195
1196 * data.c: Avoid integer truncation in expressions involving floats.
1197 * data.c: Include <intprops.h>.
1198 (arith_driver): When there's an integer overflow in an expression
1199 involving floating point, convert the integers to floating point
1200 so that the resulting value does not suffer from catastrophic
1201 integer truncation. For example, on a 64-bit host (* 4
1202 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1203 Do not rely on undefined behavior after integer overflow.
1204
1205 merge count_size_as_multibyte, parse_str_to_multibyte
1206 * character.c, character.h (count_size_as_multibyte):
1207 Rename from parse_str_to_multibyte; all uses changed.
1208 Check for integer overflow.
1209 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1210 since it's now a duplicate of the other. This is more of
1211 a character than a buffer op, so better that it's in character.c.
1212 * fns.c, print.c: Adjust to above changes.
1213
1214 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1215
1216 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1217
1218 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1219
1220 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1221 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1222 (x_clipboard_manager_save): Now static.
1223 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1224
1225 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1226 (crypto_hash_function): Now static.
1227 Fix pointer signedness problems. Avoid unnecessary initializations.
1228
1229 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1230
1231 * termhooks.h (Vselection_alist): Make it terminal-local.
1232
1233 * terminal.c (create_terminal): Initialize it.
1234
1235 * xselect.c: Support for clipboard managers.
1236 (Vselection_alist): Move to termhooks.h as terminal-local var.
1237 (LOCAL_SELECTION): New macro.
1238 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1239 (symbol_to_x_atom): Remove gratuitous arg.
1240 (x_handle_selection_request, lisp_data_to_selection_data)
1241 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1242 (x_own_selection, x_get_local_selection, x_convert_selection):
1243 New arg, specifying work frame. Use terminal-local Vselection_alist.
1244 (some_frame_on_display): Delete unused function.
1245 (Fx_own_selection_internal, Fx_get_selection_internal)
1246 (Fx_disown_selection_internal, Fx_selection_owner_p)
1247 (Fx_selection_exists_p): New optional frame arg.
1248 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1249 (x_handle_selection_clear): Don't treat other terminals with the
1250 same keyboard specially. Use the terminal-local Vselection_alist.
1251 (x_clear_frame_selections): Use Frun_hook_with_args.
1252
1253 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1254
1255 * xterm.h: Add support for those atoms.
1256
1257 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1258
1259 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1260 (converted_selections, conversion_fail_tag): New global variables.
1261 (x_selection_request_lisp_error): Free the above.
1262 (x_get_local_selection): Remove unnecessary code.
1263 (x_reply_selection_request): Args changed; handle arbitrary array
1264 of converted selections stored in converted_selections.
1265 Separate the XChangeProperty and SelectionNotify steps.
1266 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1267 (x_convert_selection): New function.
1268 (x_handle_selection_event): Simplify.
1269 (x_get_foreign_selection): Don't ignore incoming requests while
1270 waiting for an answer; this will fail when we implement
1271 SAVE_TARGETS, and seems unnecessary anyway.
1272 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1273 (Vx_sent_selection_functions): Doc fix.
1274
1275 2011-05-26 Leo Liu <sdl.web@gmail.com>
1276
1277 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)

1280
1281 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1282
1283 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1284 for fringe update if it has periodic bitmap.
1285 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1286 and fringe_bitmap_periodic_p.
1287
1288 * fringe.c (get_fringe_bitmap_data): New function.
1289 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1290 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1291 row. Mark glyph row for fringe update if periodicity changed.
1292
1293 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1294 for fringe update unless it has periodic bitmap.

1298 * xdisp.c (get_next_display_element): Set correct it->face_id for
1299 a static composition.
1300
1301 2011-05-24 Leo Liu <sdl.web@gmail.com>
1302
1303 * deps.mk (fns.o):
1304 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1305
1306 * fns.c (crypto_hash_function, Fsha1): New function.
1307 (Fmd5): Use crypto_hash_function.
1308 (syms_of_fns): Add Ssha1.
1309
1310 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1311
1312 * gnutls.c: Remove unused macros.
1313 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1314 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1315 Remove macros that are defined and never used.
1316 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1317
1318 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1319
1320 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1321 (Fx_get_selection_internal): Minor cleanup.
1322 (Fx_own_selection_internal): Rename arguments for consistency with
1323 select.el.
1324
1325 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1326
1327 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1328
1329 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1330
1331 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1332
1333 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1334
1335 * dispnew.c (scrolling_window): Don't exclude the case that the
1336 last enabled row in the desired matrix touches the bottom boundary.
1337
1338 2011-05-21 Glenn Morris <rgm@gnu.org>
1339
1340 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1341 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1342 and add some more files.
1343
1344 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1345
1346 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1347 report_file_error introduced by the change from 2011-05-07.
1348
1349 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1350
1351 * systime.h (Time): Define only if emacs is defined.
1352 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1353 where the include path doesn't have X11/X.h by default. See
1354 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1355
1356 2011-05-20 Kenichi Handa <handa@m17n.org>
1357
1358 * composite.c (find_automatic_composition): Fix previous change.
1359
1360 2011-05-20 Glenn Morris <rgm@gnu.org>
1361
1362 * lisp.mk: New file, split from Makefile.in.
1363 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1364 (shortlisp): Remove.
1365 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1366
1367 2011-05-19 Glenn Morris <rgm@gnu.org>
1368
1369 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1370 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1371 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1372 (lisp): Set the order to that of loadup.el.
1373 (shortlisp): Make it a copy of $lisp.
1374 (SOME_MACHINE_LISP): Remove.
1375 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1376 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1377
1378 2011-05-18 Kenichi Handa <handa@m17n.org>
1379
1380 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1381 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1382 (find_automatic_composition): Mostly rewrite for efficiency.
1383
1384 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1385
1386 * makefile.w32-in: Update dependencies.
1387
1388 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1389
1390 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1391 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1392
1393 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1394
1395 Fix some integer overflow issues, such as string length overflow.
1396
1397 * insdel.c (count_size_as_multibyte): Check for string overflow.
1398
1399 * character.c (lisp_string_width): Check for string overflow.
1400 Use EMACS_INT, not int, for string indexes and lengths; in
1401 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1402 the resulting string length overflows an EMACS_INT; instead,
1403 report a string overflow if no precision given. When checking for
1404 precision exhaustion, use a check that cannot possibly have
1405 integer overflow. (Bug#8675)
1406 * character.h (lisp_string_width): Adjust to new signature.
1407
1408 * alloc.c (string_overflow): New function.
1409 (Fmake_string): Use it. This doesn't change behavior, but saves
1410 a few bytes and will simplify future changes.
1411 * character.c (string_escape_byte8): Likewise.
1412 * lisp.h (string_overflow): New decl.
1413
1414 Fixups, following up to the user-interface timestamp change.
1415 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1416 for UI timestamps, instead of unsigned long.
1417 * msdos.c (mouse_get_pos): Likewise.
1418 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1419 * w32gui.h (Time): Define by including "systime.h" rather than by
1420 declaring it ourselves. (Bug#8664)
1421
1422 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1423 * image.c (clear_image_cache): Likewise.
1424
1425 * term.c (term_mouse_position): Don't assume time_t wraparound.
1426
1427 Be more systematic about user-interface timestamps.
1428 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1429 and sometimes 'EMACS_UINT', to represent these timestamps.
1430 This change causes it to use 'Time' uniformly, as that's what X uses.
1431 This makes the code easier to follow, and makes it easier to catch
1432 integer overflow bugs such as Bug#8664.
1433 * frame.c (Fmouse_position, Fmouse_pixel_position):
1434 Use Time, not unsigned long, for user-interface timestamps.
1435 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1436 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1437 * keyboard.h (last_event_timestamp): Likewise.
1438 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1439 * menu.h (xmenu_show): Likewise.
1440 * term.c (term_mouse_position): Likewise.
1441 * termhooks.h (struct input_event.timestamp): Likewise.
1442 (struct terminal.mouse_position_hook): Likewise.
1443 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1444 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1445 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1446 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1447 what it was before.
1448 * menu.h, termhooks.h: Include "systime.h", for Time.
1449
1450 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1451 Don't assume that the difference between two unsigned long values
1452 can fit into an integer. At this point, we know button_down_time
1453 <= event->timestamp, so the difference must be nonnegative, so
1454 there's no need to cast the result if double-click-time is
1455 nonnegative, as it should be; check that it's nonnegative, just in
1456 case. This bug is triggered when events are more than 2**31 ms
1457 apart (about 25 days). (Bug#8664)
1458
1459 * xselect.c (last_event_timestamp): Remove duplicate decl.
1460 (x_own_selection): Remove needless cast to unsigned long.
1461
1462 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1463 that always fit in int. Use a sentinel instead of a counter, to
1464 avoid a temp and to allay GCC's concerns about possible int overflow.
1465 * frame.h (struct frame): Use int for menu_bar_items_used
1466 instead of EMACS_INT, since it always fits in int.
1467
1468 * menu.c (grow_menu_items): Check for int overflow.
1469
1470 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1471
1472 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1473 Before, the code was not consistent. These values cannot exceed
1474 2**31 - 1 so there's no need to make them unsigned.
1475 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1476 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1477 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1478 as modifiers.
1479 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1480
1481 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1482 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1483 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1484 presumably because the widths might not match.
1485
1486 * window.c (size_window): Avoid needless test at loop start.
1487
1488 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1489
1490 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1491
1492 2011-05-12 Drew Adams <drew.adams@oracle.com>
1493
1494 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1495
1496 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1497
1498 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1499 `width' to `bar_area_x' and `bar_area_width', respectively.
1500 (x_scroll_run): Take account of fringe background extension.
1501
1502 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1503 Rename local vars `left' and `width' to `bar_area_x' and
1504 `bar_area_width', respectively.
1505 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1506 background extension.
1507
1508 2011-05-10 Jim Meyering <meyering@redhat.com>
1509
1510 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1511
1512 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1513
1514 * image.c (Finit_image_library): Return t for built-in image types,
1515 like pbm and xbm. (Bug#8640)
1516
1517 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1518
1519 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1520
1521 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1522
1523 * w32console.c (Fset_screen_color): Doc fix.
1524 (Fget_screen_color): New function.
1525 (syms_of_ntterm): Defsubr it.
1526
1527 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1528 unlink the temporary file if Fcall_process didn't create it in the
1529 first place.
1530 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1531 child process will be redirected to a file specified with `:file'.
1532 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1533 cue to call_process_cleanup not to close that handle.
1534
1535 2011-05-07 Ben Key <bkey76@gmail.com>
1536
1537 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1538 one of two shell specific rules, either bootstrap-temacs-CMD or
1539 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1540 to the previous implementation of the bootstrap-temacs rule.
1541 The bootstrap-temacs-CMD rule is similar to the previous
1542 implementation of the bootstrap-temacs rule except that it
1543 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1544 variable.
1545
1546 These changes, along with some changes to nt/configure.bat,
1547 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1548 earlier fix to add support for --cflags and --ldflags options
1549 that include quotes so that it works whether make uses cmd or
1550 sh as the shell.
1551
1552 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1553
1554 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1555 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1556 is a constant.
1557 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1558 a string. Handle both cases.
1559 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1560 (Fdbus_register_method): Use Qinvalid_function.
1561
1562 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1563
1564 * makefile.w32-in: Update dependencies.
1565 (LISP_H): Add inttypes.h and stdin.h.
1566 (PROCESS_H): Add unistd.h.
1567
1568 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1569
1570 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1571 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1572
1573 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1574
1575 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1576
1577 * term.c (vfatal): Remove stray call to va_end.
1578 It's not needed and the C Standard doesn't allow it here anyway.
1579
1580 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1581 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1582
1583 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1584 bytes.
1585
1586 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1587
1588 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1589
1590 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1591
1592 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1593
1594 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1595
1596 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1597 * charset.c (Fdefine_charset_internal): Don't initialize
1598 charset.code_space[15]. The value was garbage, on hosts with
1599 32-bit int (Bug#8600).
1600
1601 * lread.c (read_integer): Be more consistent with string-to-number.
1602 Use string_to_number to do the actual conversion; this avoids
1603 rounding errors and fixes some other screwups. Without this fix,
1604 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1605 (digit_to_number): Move earlier, for benefit of read_integer.
1606 Return -1 if the digit is out of range for the base, -2 if it is
1607 not a digit in any supported base. (Bug#8602)
1608
1609 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1610
1611 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1612 to match comment at start of function. This also removes a
1613 GCC warning about overflow in a 32+64-bit port.
1614
1615 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1616
1617 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1618 Reported by Stefan Monnier in
1619 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1620 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1621 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1622
1623 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1624 (EMACS_UINTPTR): Likewise, with uintptr_t.
1625
1626 * lisp.h: Prefer 64-bit EMACS_INT if available.
1627 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1628 on 32-bit hosts that have 64-bit int, so that they can access
1629 large files.
1630 However, temporarily disable this change unless the temporary
1631 symbol WIDE_EMACS_INT is defined.
1632
1633 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1634
1635 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1636 This removes an assumption that EMACS_INT and long are the same
1637 width as pointers. The assumption is true for Emacs porting targets
1638 now, but we want to make other targets possible.
1639 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1640 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1641 In the rest of the code, change types of integers that hold casted
1642 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1643 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1644 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1645 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1646 No need to cast type when ORing.
1647 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1648 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1649 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1650 assume EMACS_INT is the same width as char *.
1651 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1652 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1653 Remove no-longer-needed casts.
1654 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1655 (xg_tool_bar_help_callback, xg_make_tool_item):
1656 Use EMACS_INTPTR to hold an integer
1657 that will be cast to void *; this can avoid a GCC warning
1658 if EMACS_INT is not the same width as void *.
1659 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1660 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1661 (current_message_1, set_message_1):
1662 Use a local to convert to proper width without a cast.
1663 * xmenu.c (dialog_selection_callback): Likewise.
1664
1665 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1666 Also, don't assume VALBITS / RAND_BITS is less than 5,
1667 and don't rely on undefined behavior when shifting a 1 left into
1668 the sign bit.
1669 * lisp.h (get_random): Change signature to match.
1670
1671 * lread.c (hash_string): Use size_t, not int, for hash computation.
1672 Normally we prefer signed values; but hashing is special, because
1673 it's better to use unsigned division on hash table sizes so that
1674 the remainder is nonnegative. Also, size_t is the natural width
1675 for hashing into memory. The previous code used 'int', which doesn't
1676 retain enough info to hash well into very large tables.
1677 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1678
1679 * dbusbind.c: Don't possibly lose pointer info when converting.
1680 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1681 Use XPNTR rather than XHASH, so that the high-order bits of
1682 the pointer aren't lost when converting through void *.
1683
1684 * eval.c (Fautoload): Don't double-shift a pointer.
1685
1686 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1687
1688 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1689
1690 * gnutls.c (DEF_GNUTLS_FN):
1691 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1692
1693 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1694
1695 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
1696 marker. (Bug#8610)
1697
1698 2011-05-05 Eli Zaretskii <eliz@gnu.org>

1823 rather than `XVECTOR (FOO)->size'.
1824
1825 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of

1868 (command_loop_1): Run `delayed-warnings-hook'
1869 if Vdelayed_warnings_list is non-nil.
1870 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
1871 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
1872
1873 2011-04-28 Eli Zaretskii <eliz@gnu.org>
1874
1875 * doprnt.c (doprnt): Don't return value smaller than the buffer
1876 size if the message was truncated. (Bug#8545).
1877

1891 2011-04-27 Eli Zaretskii <eliz@gnu.org>
1892
1893 Improve `doprnt' and its usage. (Bug#8545)
1894 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
1895 `format_end'. Remove support for %l as a conversion specifier.
1896 Don't use xrealloc. Improve diagnostics when the %l size modifier
1897 is used. Update the commentary.
1898
1899 * eval.c (verror): Simplify calculation of size_t.
1900
1901 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
1902 messages.
1903
1904 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
1905
1906 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
1907 change.
1908
1909 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1910
1911 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
1912 This makes this file independent of the recent pseudovector change.
1913
1914 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
1915
1916 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
1917
1918 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
1919 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
1920 Remove unused local.
1921 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
1922
1923 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
1924 GCC 4.6.0 optimizes based on type-based alias analysis.
1925 For example, if b is of type struct buffer * and v of type struct
1926 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
1927 != &v->size, and therefore "v->size = 1; b->size = 2; return
1928 v->size;" must therefore return 1. This assumption is incorrect
1929 for Emacs, since it type-puns struct Lisp_Vector * with many other
1930 types. To fix this problem, this patch adds a new type struct
1931 vectorlike_header that documents the constraints on layout of vectors
1932 and pseudovectors, and helps optimizing compilers not get fooled
1933 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
1934 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
1935 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
1936 the size member.
1937 (XSETPVECTYPE): Rewrite in terms of new macro.
1938 (XSETPVECTYPESIZE): New macro, specifying both type and size.
1939 This is a bit clearer, and further avoids the possibility of
1940 undesirable aliasing.
1941 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
1942 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
1943 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
1944 since Lisp_Subr is a special case (no "next" field).
1945 (ASIZE): Now uses header.size rather than size.
1946 All previous uses of XVECTOR (foo)->size replaced to use this macro,
1947 to avoid the hassle of writing XVECTOR (foo)->header.size.
1948 (struct vectorlike_header): New type.
1949 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
1950 object, to help avoid aliasing.
1951 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
1952 (SUBRP): Likewise, since Lisp_Subr is a special case.
1953 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
1954 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
1955 (struct Lisp_Hash_Table): Combine first two members into a single
1956 struct vectorlike_header member. All uses of "size" and "next" members
1957 changed to be "header.size" and "header.next".
1958 * buffer.h (struct buffer): Likewise.
1959 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
1960 * frame.h (struct frame): Likewise.
1961 * process.h (struct Lisp_Process): Likewise.
1962 * termhooks.h (struct terminal): Likewise.
1963 * window.c (struct save_window_data, struct saved_window): Likewise.
1964 * window.h (struct window): Likewise.
1965 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
1966 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
1967 * buffer.c (init_buffer_once): Likewise.
1968 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
1969 special case.
1970 * process.c (Fformat_network_address): Use local var for size,
1971 for brevity.
1972
1973 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
1974
1975 Make the Lisp reader and string-to-float more consistent (Bug#8525)
1976 * data.c (atof): Remove decl; no longer used or needed.
1977 (digit_to_number): Move to lread.c.
1978 (Fstring_to_number): Use new string_to_number function, to be
1979 consistent with how the Lisp reader treats infinities and NaNs.
1980 Do not assume that floating-point numbers represent EMACS_INT
1981 without losing information; this is not true on most 64-bit hosts.
1982 Avoid double-rounding errors, by insisting on integers when
1983 parsing non-base-10 numbers, as the documentation specifies.
1984 * lisp.h (string_to_number): New decl, replacing ...
1985 (isfloat_string): Remove.
1986 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
1987 (read1): Do not accept +. and -. as integers; this
1988 appears to have been a coding error. Similarly, do not accept
1989 strings like +-1e0 as floating point numbers. Do not report
1990 overflow for integer overflows unless the base is not 10 which
1991 means we have no simple and reliable way to continue.
1992 Break out the floating-point parsing into a new
1993 function string_to_number, so that Fstring_to_number parses
1994 floating point numbers consistently with the Lisp reader.
1995 (digit_to_number): Move here from data.c. Make it static inline.
1996 (E_CHAR, EXP_INT): Remove, replacing with ...
1997 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
1998 (string_to_number): New function, replacing isfloat_string.
1999 This function checks for valid syntax and produces the resulting
2000 Lisp float number too. Rework it so that string-to-number
2001 no longer mishandles examples like "1.0e+". Use strtoumax,
2002 so that overflow for non-base-10 numbers is reported only when
2003 there's no portable and simple way to convert to floating point.
2004
2005 * textprop.c (set_text_properties_1): Rewrite for clarity,
2006 and to avoid GCC warning about integer overflow.
2007
2008 * intervals.h (struct interval): Use EMACS_INT for members
2009 where EMACS_UINT might cause problems. See
2010 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2011 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2012 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2013 All uses changed.
2014 (offset_intervals): Tell GCC not to worry about length overflow
2015 when negating a negative length.
2016
2017 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2018 (overrun_check_free): Likewise.
2019
2020 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2021 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2022 word size.
2023
2024 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2025 (gnutls_make_error): Rename local to avoid shadowing.
2026 (gnutls_emacs_global_deinit): ifdef out; not used.
2027 (Fgnutls_boot): Use const for pointer to readonly storage.
2028 Comment out unused local. Fix pointer signedness problems.
2029
2030 * lread.c (openp): Don't stuff size_t into an 'int'.
2031 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2032 about possible signed overflow.
2033
2034 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2035 (GDK_KEY_g): Don't define if already defined.
2036 (xg_prepare_tooltip): Avoid pointer signedness problem.
2037 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2038
2039 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2040 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2041
2042 * xfns.c (Fx_window_property): Simplify a bit,
2043 to make a bit faster and to avoid GCC 4.6.0 warning.
2044 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2045
2046 * fns.c (internal_equal): Don't assume size_t fits in int.
2047
2048 * alloc.c (compact_small_strings): Tighten assertion a little.
2049
2050 Replace pEd with more-general pI, and fix some printf arg casts.
2051 * lisp.h (pI): New macro, generalizing old pEd macro to other
2052 conversion specifiers. For example, use "...%"pI"d..." rather
2053 than "...%"pEd"...".
2054 (pEd): Remove. All uses replaced with similar uses of pI.
2055 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2056 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2057 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2058 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2059 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2060 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2061 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2062 64-bit hosts.
2063 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2064 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2065 * print.c (safe_debug_print, print_object): Likewise.
2066 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2067 to int.
2068 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2069 avoiding the 0 flag, which is not portable.
2070 * process.c (Fmake_network_process): Use pI to avoid cast.
2071 * region-cache.c (pp_cache): Likewise.
2072 * xdisp.c (decode_mode_spec): Likewise.
2073 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2074 behavior on 64-bit hosts with printf arg.
2075 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2076 (x_stop_queuing_selection_requests): Likewise.
2077 (x_get_window_property): Don't truncate byte count to an 'int'
2078 when tracing.
2079
2080 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2081 here, since it parses constructs like leading '-' and spaces,
2082 which are not wanted; and it overflows with large numbers.
2083 Instead, simply match F[0-9]+, which is what is wanted anyway.
2084
2085 * alloc.c: Remove unportable assumptions about struct layout.
2086 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2087 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2088 (allocate_vectorlike, make_pure_vector): Use the new macros,
2089 plus offsetof, to remove unportable assumptions about struct layout.
2090 These assumptions hold on all porting targets that I know of, but
2091 they are not guaranteed, they're easy to remove, and removing them
2092 makes further changes easier.
2093

2259
2260 * character.c (char_string): Use %x to display the (unsigned)

2389 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
2390

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

3179
3180 * sound.c (sound_warning): Don't crash if arg contains a printf format.
3181
3182 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
3183 printf-like functions.
3184 (tiff_load): Add casts to remove these marks before passing them
3185 to system-supplied API.
3186
3187 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3188
3189 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3190 This avoids several warnings with gcc -Wstrict-overflow.
3191 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3192 directly, rather than having caller test rule sign. This avoids
3193 some unnecessary tests.
3194 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3195 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3196 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3197
3198 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3199 (xfont_open): Avoid unnecessary tests.
3200
3201 * composite.c (composition_gstring_put_cache): Use unsigned integer.

3208 (COMPOSITION_DECODE_RULE): Use it.
3209 * composite.c (get_composition_id): Remove unused local vars,
3210 by using the new macro.
3211
3212 * textprop.c (set_text_properties_1): Change while to do-while,
3213 since the condition is always true at first.
3214
3215 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3216 (interval_deletion_adjustment): Return unsigned value.
3217 All uses changed.
3218
3219 * process.c (list_processes_1, create_pty, read_process_output):
3220 (exec_sentinel): Remove vars that were set but not used.
3221 (create_pty): Remove unnecessary "volatile"s.
3222 (Fnetwork_interface_info): Avoid possibility of int overflow.
3223 (read_process_output): Do adaptive read buffering even if carryover.
3224 (read_process_output): Simplify nbytes computation if buffered.
3225
3226 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
3227
3228 * syntax.c (scan_words): Remove var that was set but not used.
3229 (update_syntax_table): Use unsigned instead of int.
3230
3231 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
3232 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
3233 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
3234
3235 * print.c (print_error_message): Avoid int overflow.
3236
3237 * font.c (font_list_entities): Redo for clarity,
3238 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3239
3240 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3241 (font_score): Avoid potential overflow in diff calculation.
3242
3243 * fns.c (substring_both): Remove var that is set but not used.
3244 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3245
3246 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3247
3248 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3249 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3250 can always succeed if overflow has undefined behavior.
3251
3252 * search.c (boyer_moore, wordify): Remove vars set but not used.
3253 (wordify): Omit three unnecessary tests.
3254
3255 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3256 All callers changed. This avoids the need for an unused var.
3257
3258 * casefiddle.c (casify_region): Remove var that is set but not used.
3259
3260 * dired.c (file_name_completion): Remove var that is set but not used.
3261
3262 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3263

3265 (Finsert_file_contents): Remove unnecessary code checking fd.
3266
3267 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3268 Check for integer overflow on size calculations.
3269
3270 * buffer.c (Fprevious_overlay_change): Remove var that is set
3271 but not used.
3272
3273 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3274 Remove vars that are set but not used.
3275 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3276 (timer_check_2): Mark vars as initialized.
3277
3278 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3279
3280 * image.c (lookup_image): Remove var that is set but not used.
3281 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3282
3283 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3284 that are set but not used.
3285
3286 * xfns.c (make_invisible_cursor): Don't return garbage
3287 if XCreateBitmapFromData fails (Bug#8410).
3288
3289 * xselect.c (x_get_local_selection, x_handle_property_notify):
3290 Remove vars that are set but not used.
3291
3292 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

3296 Remove var that is set but not used.
3297 (scroll_bar_windows_size): Now size_t, not int.
3298 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3299 Check for overflow.
3300
3301 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3302 (map_tty_color) [!defined MSDOS]: Likewise.
3303
3304 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3305
3306 * coding.c: Remove vars that are set but not used.
3307 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3308 All callers changed.
3309 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3310 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3311 (decode_coding_charset): Remove vars that are set but not used.
3312
3313 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3314 that is set but not used.
3315
3316 * print.c (print_object): Remove var that is set but not used.
3317
3318 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3319 The gnulib version avoids calling malloc in the usual case,
3320 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3321 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3322 * filelock.c (current_lock_owner): Likewise.
3323 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3324 * sysdep.c: Include allocator.h, careadlinkat.h.
3325 (emacs_no_realloc_allocator): New static constant.
3326 (emacs_readlink): New function.
3327 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
3328 ../lib/careadlinkat.h.
3329
3330 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3331
3332 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3333 first non-nil return value).
3334
3335 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3336
3337 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3338 if not defined (Bug#8403).
3339
3340 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

3374
3375 * lread.c (lisp_file_lexically_bound_p): New function.
3376 (Fload): Bind Qlexical_binding.
3377 (readevalloop): Remove `evalfun' arg.
3378 Bind Qinternal_interpreter_environment.
3379 (Feval_buffer): Bind Qlexical_binding.
3380 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3381 Mark as dynamic.
3382 (syms_of_lread): Declare `lexical-binding'.
3383
3384 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3385
3386 * keyboard.c (eval_dyn): New fun.
3387 (menu_item_eval_property): Use it.
3388
3389 * image.c (parse_image_spec): Use Ffunctionp.
3390
3391 * fns.c (concat, mapcar1): Accept byte-code-functions.
3392
3393 * eval.c (Fsetq): Handle lexical vars.
3394 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3395 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3396 (FletX, Flet): Obey lexical binding.
3397 (Fcommandp): Handle closures.
3398 (Feval): New `lexical' arg.
3399 (eval_sub): New function extracted from Feval. Use it almost
3400 everywhere where Feval was used. Look up vars in lexical env.
3401 Handle closures.
3402 (Ffunctionp): Move from subr.el.
3403 (Ffuncall): Handle closures.
3404 (apply_lambda): Remove `eval_flags'.
3405 (funcall_lambda): Handle closures and new byte-code-functions.
3406 (Fspecial_variable_p): New function.
3407 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3408 but without exporting it to Lisp.
3409

3411 * data.c (Finteractive_form): Handle closures.
3412
3413 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3414 interactive spec.
3415
3416 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3417 New byte-codes.
3418 (exec_byte_code): New function extracted from Fbyte_code to handle new
3419 calling convention for byte-code-functions. Add new byte-codes.
3420
3421 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3422
3423 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3424
3425 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3426
3427 * xdisp.c (redisplay_internal): Fix prototype.
3428
3429 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3430
3431 * xdisp.c (SCROLL_LIMIT): New macro.
3432 (try_scrolling): Use it when setting scroll_limit.
3433 Limit scrolling to 100 screen lines.
3434 (redisplay_window): Even when falling back on "recentering",
3435 position point in the window according to scroll-conservatively,
3436 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3437
3438 (try_scrolling): When point is above the window, allow searching
3439 as far as scroll_max, or one screenful, to compute vertical
3440 distance from PT to the scroll margin position. This prevents
3441 try_scrolling from unnecessarily failing when
3442 scroll-conservatively is set to a value slightly larger than the
3443 window height. Clean up the case of PT below the margin at bottom
3444 of window: scroll_max can no longer be INT_MAX. When aggressive
3445 scrolling is in use, don't let point enter the opposite scroll
3446 margin as result of the scroll.
3447 (syms_of_xdisp) <scroll-conservatively>: Document the
3448 threshold of 100 lines for never-recentering scrolling.

3457 (redisplay_internal): Remove parameter `preserve_echo_area',
3458 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3459
3460 * indent.c (Fvertical_motion):
3461 * window.c (window_scroll_pixel_based, Frecenter):
3462 Don't pass `need_y_p' to `move_it_by_lines'.
3463
3464 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3465
3466 * eval.c (struct backtrace): Don't cheat with negative numbers, but do

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

3496 Don't assume string length fits in int.
3497 (keyremap_step, read_key_sequence): Use size_t for sizes.
3498 (read_key_sequence): Don't check last_real_key_start redundantly.
3499
3500 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3501 instead of alloca (Bug#8344).
3502
3503 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3504 (Fbacktrace_frame): Don't assume nframes fits in int.
3505
3506 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3507
3508 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3509 concerns.
3510
3511 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3512
3513 * cm.c (calccost): Turn while-do into do-while, for clarity.
3514
3515 * keyboard.c (syms_of_keyboard): Use the same style as later
3516 in this function when indexing through an array. This also
3517 works around GCC bug 48267.
3518
3519 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3520

3524 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3525
3526 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3527 This avoids undefined behavior on integer overflow, and is a bit
3528 more convenient anyway since it is compared to a size_t variable.
3529
3530 Variadic C functions now count arguments with size_t, not int.
3531 This avoids an unnecessary limitation on 64-bit machines, which
3532 caused (substring ...) to crash on large vectors (Bug#8344).

3541 (funcall_lambda, mark_backtrace): Likewise.
3542 * fns.c (concat): Likewise.
3543 * frame.c (x_set_frame_parameters): Likewise.
3544 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3545 0 if not found, not -1. All callers changed.
3546
3547 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3548 (stack_copy_size): Now size_t, not int.
3549 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

3574 Vcommand_hook_internal.

3750 * emacs.c (Fkill_emacs):
3751 * editfns.c (save_excursion_restore):
3752 * cmds.c (internal_self_insert):
3753 * callint.c (Fcall_interactively):
3754 * buffer.c (Fkill_all_local_variables):
3755 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3756 Use Frun_hooks.
3757 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3758 unconditionnaly since it does the check itself.

3760 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3761
3762 Fix more problems found by GCC 4.5.2's static checks.
3763
3764 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3765 the first time through the loop, since we know p0 < p1 then.
3766 This also avoids a gcc -Wstrict-overflow warning.
3767
3768 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3769 leading to a memory leak, possible in functions like
3770 load_charset_map_from_file that can allocate an unbounded number
3771 of objects (Bug#8318).
3772
3773 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3774 that could (at least in theory) be that large.
3775
3776 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3777 This is less likely to overflow, and avoids undefined behavior if
3778 overflow does occur. All callers changed. Use strtoul to scan
3779 for the unsigned long integer.
3780 (pint2hrstr): Simplify and tune code slightly.
3781 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
3782
3783 * scroll.c (do_scrolling): Work around GCC bug 48228.
3784 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
3785
3786 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
3787 This also avoids a warning with gcc -Wstrict-overflow.
3788 (validate_x_resource_name): Simplify count usage.
3789 This also avoids a warning with gcc -Wstrict-overflow.
3790
3791 * fileio.c (Fcopy_file): Report error if fchown or fchmod
3792 fail (Bug#8306).
3793
3794 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
3795
3796 * process.c (Fmake_network_process): Use socklen_t, not int,
3797 where POSIX says socklen_t is required in portable programs.
3798 This fixes a porting bug on hosts like 64-bit HP-UX, where
3799 socklen_t is wider than int (Bug#8277).
3800 (Fmake_network_process, server_accept_connection):
3801 (wait_reading_process_output, read_process_output):
3802 Likewise.
3803
3804 * process.c: Rename or move locals to avoid shadowing.
3805 (list_processes_1, Fmake_network_process):
3806 (read_process_output_error_handler, exec_sentinel_error_handler):

3808 (Fmake_network_process): Define label "retry_connect" only if needed.
3809 (Fnetwork_interface_info): Fix pointer signedness.
3810 (process_send_signal): Add cast to avoid pointer signedness problem.
3811 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
3812 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
3813
3814 Make tparam.h and terminfo.c consistent.
3815 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
3816 Include tparam.h instead, since it declares them.
3817 * cm.h (PC): Remove extern decl; tparam.h now does this.
3818 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3819 * terminfo.c: Include tparam.h, to check interfaces.
3820 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3821 (tparam): Adjust signature to match interface in tparam.h;
3822 this removes some undefined behavior. Check that outstring and len
3823 are zero, which they always are with Emacs.
3824 * tparam.h (PC, BC, UP): New extern decls.
3825
3826 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3827 (xftfont_open): Rename locals to avoid shadowing.
3828
3829 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
3830 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
3831 (OTF_TAG_SYM): Omit macro if not needed.

3834 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
3835 Rename locals to avoid shadowing.
3836
3837 * xfont.c (xfont_list_family): Mark var as initialized.
3838
3839 * xml.c (make_dom): Now static.
3840
3841 * composite.c (composition_compute_stop_pos): Rename local to
3842 avoid shadowing.
3843 (composition_reseat_it): Remove unused locals.
3844 (find_automatic_composition, composition_adjust_point): Likewise.
3845 (composition_update_it): Mark var as initialized.
3846 (find_automatic_composition): Mark vars as initialized,
3847 with a FIXME (Bug#8290).
3848
3849 character.h: Rename locals to avoid shadowing.
3850 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
3851 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
3852 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
3853 (BUF_DEC_POS): Be more systematic about renaming local temporaries
3854 to avoid shadowing.
3855
3856 * textprop.c (property_change_between_p): Remove; unused.
3857
3858 * intervals.c (interval_start_pos): Now static.

3861
3862 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
3863 Rename locals to avoid shadowing.
3864
3865 * sound.c (wav_play, au_play, Fplay_sound_internal):
3866 Fix pointer signedness.
3867 (alsa_choose_format): Remove unused local var.
3868 (wav_play): Initialize a variable to 0, to prevent undefined
3869 behavior (Bug#8278).
3870
3871 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
3872
3873 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
3874
3875 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
3876 clobbering (Bug#8298).
3877 * sysdep.c (sys_subshell): Likewise.
3878 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
3879
3880 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
3881 This should get cleaned up, so that child_setup has the
3882 same signature on all platforms.
3883
3884 * callproc.c (call_process_cleanup): Now static.
3885 (relocate_fd): Rename locals to avoid shadowing.
3886
3887 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
3888
3889 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
3890 not to be necessary, and produces flickering.
3891
3892 2011-03-20 Glenn Morris <rgm@gnu.org>
3893
3894 * config.in: Remove file.
3895
3896 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
3897
3898 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
3899 are now in src/globals.h.
3900 (syms_of_minibuf): Remove spurious & from previous change.
3901
3902 2011-03-20 Leo <sdl.web@gmail.com>
3903
3904 * minibuf.c (completing-read-function): New variable.
3905 (completing-read-default): Rename from completing-read.
3906 (completing-read): Call completing-read-function.
3907
3908 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3909
3910 * xfaces.c (Fx_load_color_file):
3911 Read color file from absolute filename (bug#8250).
3912
3913 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3914
3915 * makefile.w32-in: Update dependencies.
3916
3917 2011-03-17 Eli Zaretskii <eliz@gnu.org>
3918
3919 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
3920
3921 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

3926 (sigchld_handler): Now static.
3927
3928 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
3929 That way, the code declares only the vars that it needs.
3930 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
3931 * s/cygwin.h (PTY_ITERATION): Likewise.
3932 * s/darwin.h (PTY_ITERATION): Likewise.
3933 * s/gnu-linux.h (PTY_ITERATION): Likewise.
3934
3935 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
3936 * process.c (allocate_pty): Don't declare stb unless it's needed.
3937
3938 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
3939 (CONSTANTLIM): Remove; unused.
3940 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
3941 Define only if needed.
3942
3943 * unexelf.c (unexec): Name an expression,
3944 to avoid gcc -Wbad-function-cast warning.
3945 Use a different way to cause a compilation error if anyone uses
3946 n rather than nn, a way that does not involve shadowing.
3947 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
3948
3949 * deps.mk (unexalpha.o): Remove; unused.
3950
3951 New file unexec.h, the (simple) interface for unexec (Bug#8267).
3952 * unexec.h: New file.
3953 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
3954 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
3955 Depend on unexec.h.
3956 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
3957 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
3958 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
3959 Change as necessary to match prototype in unexec.h.
3960
3961 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
3962 shadowing.
3963 (back_comment, skip_chars): Mark vars as initialized.
3964

3970
3971 * print.c (Fredirect_debugging_output): Fix pointer signedess.
3972
3973 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
3974 warning when compiling print.c.
3975
3976 * font.c (font_unparse_fcname): Abort in an "impossible" situation
3977 instead of using an uninitialized var.
3978 (font_sort_entities): Mark var as initialized.
3979
3980 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
3981
3982 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
3983 pointers to constants.

3992 (Ffillarray): Rename locals to avoid shadowing.
3993
3994 * floatfns.c (domain_error2): Define only if needed.

3996
3997 * alloc.c (mark_backtrace): Move decl from here ...
3998 * lisp.h: ... to here, so that it can be checked.
3999
4000 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
4001 (Fdefvar): Rewrite so as not to use empty "else".
4002 (lisp_indirect_variable): Name an expression,
4003 to avoid gcc -Wbad-function-cast warning.
4004 (Fdefvar): Rename locals to avoid shadowing.
4005
4006 * callint.c (quotify_arg, quotify_args): Now static.
4007 (Fcall_interactively): Rename locals to avoid shadowing.
4008 Use const pointer when appropriate.
4009
4010 * lisp.h (get_system_name, get_operating_system_release):
4011 Move decls here, to check interfaces.
4012 * process.c (get_operating_system_release): Move decl to lisp.h.
4013 * xrdb.c (get_system_name): Likewise.
4014 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4015 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4016 some of which prompt warnings from gcc -Wbad-function-cast.
4017 (Fformat_time_string, Fencode_time, Finsert_char):
4018 (Ftranslate_region_internal, Fformat):
4019 Rename or remove local vars to avoid shadowing.
4020 (Ftranslate_region_internal): Mark var as initialized.
4021
4022 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
4023 avoid shadowing.
4024
4025 * lisp.h (eassert): Check that the argument compiles, even if
4026 ENABLE_CHECKING is not defined.
4027
4028 * data.c (Findirect_variable): Name an expression, to avoid
4029 gcc -Wbad-function-cast warning.
4030 (default_value, arithcompare, arith_driver, arith_error): Now static.
4031 (store_symval_forwarding): Rename local to avoid shadowing.
4032 (Fmake_variable_buffer_local, Fmake_local_variable):
4033 Mark variables as initialized.
4034 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
4035
4036 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
4037 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4038 Rename locals to avoid shadowing.
4039 (mark_stack): Move local variables into the #ifdef region where
4040 they're used.
4041 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4042 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4043 needed otherwise.
4044 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4045 (GC_STRING_CHARS): Remove; not used.
4046 (Fmemory_limit): Cast sbrk's returned value to char *.
4047
4048 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4049 avoids undefined behavior in theory.
4050
4051 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4052
4053 Use functions, not macros, for up- and down-casing (Bug#8254).
4054 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4055 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4056 to use the following functions instead of these macros.
4057 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4058 EMACS_INT, since callers assume the returned value fits in int.
4059 (upcase1): Likewise, for UPCASE_TABLE.
4060 (uppercasep, lowercasep, upcase): New static inline functions.
4061 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
4062 the race-condition problem in the old DOWNCASE.
4063
4064 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
4065 Rename locals to avoid shadowing.
4066 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4067 (regex_compile, re_search_2, re_match_2_internal):
4068 Remove unused local vars.
4069 (FREE_VAR): Rewrite so as not to use empty "else",
4070 which gcc can warn about.
4071 (regex_compile, re_match_2_internal): Mark locals as initialized.
4072 (RETALLOC_IF): Define only if needed.
4073 (WORDCHAR_P): Likewise. This one is never needed, but is used
4074 only in a comment talking about a compiler bug, so put inside
4075 the #if 0 of that comment.
4076 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4077 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4078 Remove; unused.
4079
4080 * search.c (boyer_moore): Rename locals to avoid shadowing.
4081 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4082 (PREV_CHAR_BOUNDARY): Likewise.
4083
4084 * search.c (simple_search): Remove unused var.
4085
4086 * dired.c (compile_pattern): Move decl from here ...
4087 * lisp.h: ... to here, so that it can be checked.
4088 (struct re_registers): New forward decl.
4089
4090 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
4091
4092 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
4093 All uses changed.
4094 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
4095 Rename locals to avoid shadowing.
4096 (Fvertical_motion): Mark locals as initialized.
4097
4098 * casefiddle.c (casify_object, casify_region): Now static.
4099 (casify_region): Mark local as initialized.
4100
4101 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4102
4103 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4104 New macros, so that the caller can use some names other than
4105 gcpro1, gcpro2, etc.
4106 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4107 of the new macros.
4108 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4109 argument, for consistency with GCPRO2_VAR, etc: it is now the
4110 prefix of the variable, not the variable itself. All uses
4111 changed.
4112 * dired.c (directory_files_internal, file_name_completion):
4113 Rename locals to avoid shadowing.
4114
4115 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4116 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4117 dired.c's scmp function, had undefined behavior.
4118 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4119 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4120 * buffer.h: ... to here, because these macros use current_buffer,
4121 and the new implementation with inline functions needs to have
4122 current_buffer in scope now, rather than later when the macros
4123 are used.
4124 (downcase, upcase1): New static inline functions.
4125 (DOWNCASE, UPCASE1): Reimplement using these functions.
4126 This avoids undefined behavior in expressions like
4127 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4128 from race conditions in accessing the global variables
4129 case_temp1 and case_temp2.
4130 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4131 * lisp.h (case_temp1, case_temp2): Remove their decls.
4132 * character.h (ASCII_CHAR_P): Move from here ...
4133 * lisp.h: ... to here, so that the inline functions mentioned
4134 above can use them.
4135
4136 * dired.c (directory_files_internal_unwind): Now static.
4137
4138 * fileio.c (file_name_as_directory, directory_file_name):
4139 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4140 Now static.
4141 (file_name_as_directory): Use const pointers when appropriate.
4142 (Fexpand_file_name): Likewise. In particular, newdir might
4143 point at constant storage, so make it a const pointer.
4144 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4145 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4146 signedness issues.
4147 (Fset_file_times, Finsert_file_contents, auto_save_error):
4148 Rename locals to avoid shadowing.
4149
4150 * minibuf.c (choose_minibuf_frame_1): Now static.
4151 (Ftry_completion, Fall_completions): Rename or remove locals
4152 to avoid shadowing.
4153
4154 * marker.c (bytepos_to_charpos): Remove; unused.
4155
4156 * lisp.h (verify_bytepos, count_markers): New decls,
4157 so that gcc does not warn that these functions aren't declared.
4158
4159 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4160 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4161 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4162 (copy_text): Remove unused local var.
4163
4164 * filelock.c (within_one_second): Now static.
4165 (lock_file_1): Rename local to avoid shadowing.
4166
4167 * buffer.c (fix_overlays_before): Mark locals as initialized.
4168 (fix_start_end_in_overlays): Likewise. This function should be
4169 simplified by using pointers-to-pointers, but that's a different
4170 matter.
4171 (switch_to_buffer_1): Now static.
4172 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4173 (report_overlay_modification): Rename locals to avoid shadowing.
4174

4577 Move these decls to tparam.h, and make them agree with what
4578 is actually in tparam.c. The previous trick of using incompatible
4579 decls in different modules does not conform to the C standard.
4580 All callers of tparam changed to use tparam's actual API.
4581 * tparam.c (tparam1, tparam, tgoto):
4582 Use const pointers where appropriate.
4583
4584 * cm.c (calccost, cmgoto): Use const pointers where appropriate.

4588 * term.c (tty_ins_del_lines, calculate_costs, struct fkey_table):
4589 (term_get_fkeys_1, append_glyphless_glyph, produce_glyphless_glyph):
4590 (turn_on_face, init_tty): Likewise.
4591 * termchar.h (struct tty_display_info): Likewise.
4592
4593 * term.c (term_mouse_position): Rename local to avoid shadowing.
4594
4595 * alloc.c (mark_ttys): Move decl from here ...
4596 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
