1 2011-06-19 Paul Eggert <eggert@cs.ucla.edu>
3 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4 This didn't break anything, but it didn't help either.
5 It's confusing to put a bogus integer in a place where the actual
8 2011-06-18 Paul Eggert <eggert@cs.ucla.edu>
10 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
11 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
13 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14 We prefer signed types, and the value cannot exceed the EMACS_INT
15 range anyway (because otherwise the length would not be representable).
16 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18 This avoids a GCC warning when WIDE_EMACS_INT.
20 * indent.c (sane_tab_width): New function.
21 (current_column, scan_for_column, Findent_to, position_indentation)
22 (compute_motion): Use it. This is just for clarity.
23 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
25 * image.c (xbm_image_p): Don't assume stated width and height fit in int.
27 * lisp.h (lint_assume): New macro.
28 * composite.c (composition_gstring_put_cache):
29 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
31 * editfns.c, insdel.c:
32 Omit unnecessary forward decls, to simplify future changes.
34 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
36 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
38 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
39 Use much-faster test for byte-length change.
40 Don't assume string byte-length fits in 'int'.
41 Check that character arg fits in 'int'.
42 (mapcar1): Declare byte as byte, for clarity.
44 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
46 * fns.c (concat): Catch string overflow earlier.
47 Do not rely on integer wraparound.
49 * dispextern.h (struct it.overlay_strings_charpos): EMACS_INT, not int.
51 2011-06-17 Paul Eggert <eggert@cs.ucla.edu>
53 * dispextern.h (struct it.selective): Now EMACS_INT, not int.
54 * xdisp.c (forward_to_next_line_start)
55 (back_to_previous_visible_line_start)
56 (reseat_at_next_visible_line_start, next_element_from_buffer):
57 Don't arbitrarily truncate the value of 'selective' to int.
59 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
61 * composite.c: Don't truncate sizes to 'int'.
62 (composition_gstring_p, composition_reseat_it)
63 (composition_adjust_point): Use EMACS_INT, not int.
64 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
65 not EMACS_UINT, for indexes.
67 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
69 * buffer.c: Include <verify.h>.
70 (struct sortvec.priority, struct sortstr.priority):
71 Now EMACS_INT, not int.
72 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
73 (struct sortstr.size, record_overlay_string)
74 (struct sortstrlist.size, struct sortlist.used):
75 Don't truncate size to int.
76 (record_overlay_string): Check for size-calculation overflow.
77 (init_buffer_once): Check at compile-time, not run-time.
79 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
81 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
82 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
83 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
85 Improve buffer-overflow checking (Bug#8873).
86 * fileio.c (Finsert_file_contents):
87 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
88 Remove the old (too-loose) buffer overflow checks.
89 They weren't needed, since make_gap checks for buffer overflow.
90 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
91 The old code merely checked for Emacs fixnum overflow, and relied
92 on undefined (wraparound) behavior. The new code avoids undefined
93 behavior, and also checks for ptrdiff_t and/or size_t overflow.
95 * editfns.c (Finsert_char): Don't dump core with very negative counts.
96 Tune. Don't use wider integers than needed. Don't use alloca.
97 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
99 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
101 * insdel.c, lisp.h (buffer_overflow): New function.
102 (insert_from_buffer_1, replace_range, replace_range_2):
103 * insdel.c (make_gap_larger):
104 * editfns.c (Finsert_char):
105 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
107 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
109 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
111 Integer overflow and signedness fixes (Bug#8873).
113 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
114 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
116 * fileio.c: Don't assume EMACS_INT fits in off_t.
117 (emacs_lseek): New static function.
118 (Finsert_file_contents, Fwrite_region): Use it.
119 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
121 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
123 * fns.c: Don't overflow int when computing a list length.
124 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
125 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
126 truncation on 64-bit hosts. Check for QUIT every
127 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
128 faster and is responsive enough.
129 (Flength): Report an error instead of overflowing an integer.
130 (Fsafe_length): Return a float if the value is not representable
131 as a fixnum. This shouldn't happen except in contrived situations.
132 (Fnthcdr, Fsort): Don't assume list length fits in int.
133 (Fcopy_sequence): Don't assume vector length fits in int.
135 * alloc.c: Check that resized vectors' lengths fit in fixnums.
136 (header_size, word_size): New constants.
137 (allocate_vectorlike): Don't check size overflow here.
138 (allocate_vector): Check it here instead, since this is the only
139 caller of allocate_vectorlike that could cause overflow.
140 Check that the new vector's length is representable as a fixnum.
142 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
143 The previous code was bogus. For example, next_almost_prime (32)
144 returned 39, which is undesirable as it is a multiple of 3; and
145 next_almost_prime (24) returned 25, which is a multiple of 5 so
146 why was the code bothering to check for multiples of 7?
148 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
150 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
152 Variadic C functions now count arguments with ptrdiff_t.
153 This partly undoes my 2011-03-30 change, which replaced int with size_t.
154 Back then I didn't know that the Emacs coding style prefers signed int.
155 Also, in the meantime I found a few more instances where arguments
156 were being counted with int, which may truncate counts on 64-bit
157 machines, or EMACS_INT, which may be unnecessarily wide.
158 * lisp.h (struct Lisp_Subr.function.aMANY)
159 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
160 Arg counts are now ptrdiff_t, not size_t.
161 All variadic functions and their callers changed accordingly.
162 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
163 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
164 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
165 * callint.c (Fcall_interactively): Check arg count for overflow,
166 to avoid potential buffer overrun. Use signed char, not 'int',
167 for 'varies' array, so that we needn't bother to check its size
168 calculation for overflow.
169 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
170 * eval.c (apply_lambda):
171 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
172 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
173 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
175 * callint.c (Fcall_interactively): Don't use index var as event count.
177 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
178 * mem-limits.h (SIZE): Remove; no longer used.
180 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
182 Remove unnecessary casts.
183 * xterm.c (x_term_init):
184 * xfns.c (x_set_border_pixel):
185 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
186 These aren't needed now that we assume ANSI C.
188 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
189 It's more likely to cause problems (due to unsigned overflow)
192 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
194 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
196 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
198 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
200 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
202 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
204 GLYPH_CODE_FACE returns EMACS_INT, not int.
205 * dispextern.h (merge_faces):
206 * xfaces.c (merge_faces):
207 * xdisp.c (get_next_display_element, next_element_from_display_vector):
208 Don't assume EMACS_INT fits in int.
210 * character.h (CHAR_VALID_P): Remove unused parameter.
211 * fontset.c, lisp.h, xdisp.c: All uses changed.
213 * editfns.c (Ftranslate_region_internal): Omit redundant test.
215 * fns.c (concat): Minor tuning based on overflow analysis.
216 This doesn't fix any bugs. Use int to hold character, instead
217 of constantly refetching from Emacs object. Use XFASTINT, not
218 XINT, for value known to be a character. Don't bother comparing
219 a single byte to 0400, as it's always less.
221 * floatfns.c (Fexpt):
222 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
224 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
227 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
229 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
230 Without this fix, on a 64-bit host (aset S 0 4294967386) would
231 incorrectly succeed when S was a string, because 4294967386 was
232 truncated before it was used.
234 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
235 Otherwise, an out-of-range integer could cause undefined behavior
238 * composite.c: Use int, not EMACS_INT, for characters.
239 (fill_gstring_body, composition_compute_stop_pos): Use int, not
240 EMACS_INT, for values that are known to be in character range.
241 This doesn't fix any bugs but is the usual style inside Emacs and
242 may generate better code on 32-bit machines.
244 Make sure a 64-bit char is never passed to ENCODE_CHAR.
245 This is for reasons similar to the recent CHAR_STRING fix.
246 * charset.c (Fencode_char): Check that character arg is actually
247 a character. Pass an int to ENCODE_CHAR.
248 * charset.h (ENCODE_CHAR): Verify that the character argument is no
249 wider than 'int', as a compile-time check to prevent future regressions
252 * character.c (char_string): Remove unnecessary casts.
254 Make sure a 64-bit char is never passed to CHAR_STRING.
255 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
256 by silently ignoring the top 32 bits, allowing some values
257 that were far too large to be valid characters.
258 * character.h: Include <verify.h>.
259 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
260 arguments are no wider than unsigned, as a compile-time check
261 to prevent future regressions in this area.
263 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
264 (Fsubst_char_in_region):
266 * xdisp.c (decode_mode_spec_coding):
267 Adjust to CHAR_STRING's new requirement.
268 * editfns.c (Finsert_char, Fsubst_char_in_region):
269 * fns.c (concat): Check that character args are actually
270 characters. Without this test, these functions did the wrong
271 thing with wildly out-of-range values on 64-bit hosts.
273 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
274 These casts should not be needed on 32-bit hosts, either.
275 * keyboard.c (read_char):
276 * lread.c (Fload): Remove casts to unsigned.
278 * lisp.h (UNSIGNED_CMP): New macro.
279 This fixes comparison bugs on 64-bit hosts.
280 (ASCII_CHAR_P): Use it.
281 * casefiddle.c (casify_object):
282 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
283 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
284 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
285 * dispextern.h (FACE_FROM_ID):
286 * keyboard.c (read_char): Use UNSIGNED_CMP.
288 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
289 not to EMACS_INT, to avoid GCC warning.
291 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
293 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
294 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
295 isn't needed on 32-bit machines.
297 * buffer.c (Fgenerate_new_buffer_name):
298 Use EMACS_INT for count, not int.
299 (advance_to_char_boundary): Return EMACS_INT, not int.
301 * data.c (Qcompiled_function): Now static.
303 * window.c (window_body_lines): Now static.
305 * image.c (gif_load): Rename local to avoid shadowing.
307 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
308 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
309 * alloc.c (make_save_value): Integer argument is now of type
311 (mark_object): Use ptrdiff_t, not int.
312 * lisp.h (pD): New macro.
313 * print.c (print_object): Use it.
315 * alloc.c: Use EMACS_INT, not int, to count objects.
316 (total_conses, total_markers, total_symbols, total_vector_size)
317 (total_free_conses, total_free_markers, total_free_symbols)
318 (total_free_floats, total_floats, total_free_intervals)
319 (total_intervals, total_strings, total_free_strings):
320 Now EMACS_INT, not int. All uses changed.
321 (Fgarbage_collect): Compute overall total using a double, so that
322 integer overflow is less likely to be a problem. Check for overflow
323 when converting back to an integer.
324 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
325 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
326 These were 'int' variables that could overflow on 64-bit hosts;
327 they were never used, so remove them instead of repairing them.
328 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
329 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
330 Previously, this ceilinged at INT_MAX, but that doesn't work on
332 (allocate_pseudovector): Don't use EMACS_INT when int would do.
334 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
335 (allocate_vectorlike): Check for ptrdiff_t overflow.
336 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
337 when a (possibly-narrower) signed value would do just as well.
338 We prefer using signed arithmetic, to avoid comparison confusion.
340 * alloc.c: Catch some string size overflows that we were missing.
341 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
342 for convenience in STRING_BYTES_MAX.
343 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
344 The definition here is exact; the one in lisp.h was approximate.
345 (allocate_string_data): Check for string overflow. This catches
346 some instances we weren't catching before. Also, it catches
347 size_t overflow on (unusual) hosts where SIZE_MAX <= min
348 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
349 and ptrdiff_t and EMACS_INT are both 64 bits.
351 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
352 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
353 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
355 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
357 * alloc.c (Fmake_string): Check for out-of-range init.
359 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
361 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
363 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
365 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
366 xg_get_default_scrollbar_width.
368 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
369 (int_gtk_range_get_value): Move to the scroll bar part of the file.
370 (style_changed_cb): Call update_theme_scrollbar_width and call
371 x_set_scroll_bar_default_width and xg_frame_set_char_size for
372 all frames (Bug#8505).
373 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
374 Call gtk_window_set_resizable if HAVE_GTK3.
375 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
376 and height if HAVE_GTK3 (Bug#8505).
377 (scroll_bar_width_for_theme): New variable.
378 (update_theme_scrollbar_width): New function.
379 (xg_get_default_scrollbar_width): Move code to
380 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
381 (xg_initialize): Call update_theme_scrollbar_width.
383 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
385 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
387 2011-06-12 Martin Rudalics <rudalics@gmx.at>
389 * frame.c (make_frame): Call other_buffer_safely instead of
392 * window.c (temp_output_buffer_show): Call display_buffer with
393 second argument Vtemp_buffer_show_specifiers and reset latter
394 immediately after the call.
395 (Vtemp_buffer_show_specifiers): New variable.
396 (auto_window_vscroll_p, next_screen_context_lines)
397 (Vscroll_preserve_screen_position): Remove leading asterisks from
400 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
402 Fix minor problems found by GCC 4.6.0 static checking.
403 * buffer.c (Qclone_number): Remove for now, as it's unused.
404 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
405 (record_buffer): Remove unused local.
406 * frame.c (other_visible_frames, frame_buffer_list): Now static.
407 (set_frame_buffer_list): Remove; unused.
408 * frame.h (other_visible_frames): Remove decl.
409 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
410 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
411 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
413 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
414 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
415 Define only if HAVE_GPM.
416 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
417 (update_hints_inhibit): Remove; never set. All uses removed.
418 * widgetprv.h (emacsFrameClassRec): Remove decl.
419 * window.c (delete_deletable_window): Now returns void, since it
420 wasn't returning anything.
421 (compare_window_configurations): Remove unused locals.
422 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
423 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
424 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
425 the same widths as pointers. This follows up on the 2011-05-06 patch.
426 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
428 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
430 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
432 * makefile.w32-in: Update dependencies.
433 (LISP_H): Add lib/intprops.h.
435 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
437 * image.c (gif_load): Add animation frame delay to the metadata.
438 (syms_of_image): Use DEFSYM. New symbol `delay'.
440 2011-06-11 Martin Rudalics <rudalics@gmx.at>
442 * window.c (delete_deletable_window): Re-add.
443 (Fset_window_configuration): Rewrite to handle dead buffers and
444 consequently deletable windows.
445 (window_tree, Fwindow_tree): Remove. Supply functionality in
447 (compare_window_configurations): Simplify code.
449 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
451 * image.c (imagemagick_load_image): Fix type mismatch.
452 (Fimagemagick_types): Likewise.
454 * window.h (replace_buffer_in_windows): Declare.
456 2011-06-11 Martin Rudalics <rudalics@gmx.at>
458 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
459 Qclone_number. Remove external declaration of Qdelete_window.
460 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
462 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer): Run
463 Qbuffer_list_update_hook if allowed.
464 (Fother_buffer): Rewrite doc-string. Major rewrite for new
465 buffer list implementation.
466 (other_buffer_safely): New function.
467 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
468 calls to replace_buffer_in_windows and
469 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
471 (record_buffer): Inhibit quitting and rewrite using quittable
472 functions. Run Qbuffer_list_update_hook if allowed.
473 (Frecord_buffer, Funrecord_buffer): New functions.
474 (switch_to_buffer_1, Fswitch_to_buffer): Remove. Move
475 switch-to-buffer to window.el.
476 (bury-buffer): Move to window.el.

970 (push_it): Accept second argument POSITION, where pop_it should
971 jump to continue iteration.
972 (reseat_1): Initialize bidi_it.disp_pos.

985 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
987 Malloc failure behavior now depends on size of allocation.
988 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
989 * lisp.h: Change signatures accordingly.
990 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
991 All callers changed. (Bug#8762)
993 * gnutls.c: Use Emacs's memory allocators.
994 Without this change, the gnutls library would invoke malloc etc.
995 directly, which causes problems on non-SYNC_INPUT hosts, and which
996 runs afoul of improving memory_full behavior. (Bug#8761)
997 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
998 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
999 xfree instead of the default malloc, realloc, free.
1000 (Fgnutls_boot): No need to check for memory allocation failure,
1001 since xmalloc does that for us.
1003 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1004 * category.c (hash_get_category_set):
1005 * ccl.c (ccl_driver):

1017 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
1018 (Fsxhash, Fgethash, Fputhash, Fmaphash):
1019 * image.c (make_image, search_image_cache, lookup_image)
1020 (xpm_put_color_table_h):
1021 * lisp.h (struct Lisp_Hash_Table):
1022 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1023 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1024 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1025 * alloc.c (allocate_vectorlike):
1026 Check for overflow in vector size calculations.
1027 * ccl.c (ccl_driver):
1028 Check for overflow when converting EMACS_INT to int.
1029 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1030 need to be updated by these changes.
1031 * fns.c (make_hash_table, maybe_resize_hash_table):
1032 Check for integer overflow with large hash tables.
1033 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1034 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1035 (SXHASH_REDUCE): New macro.
1036 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1037 Use it instead of discarding useful hash info with large hash values.
1038 (sxhash_float): New function.
1039 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1040 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1041 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1042 Rewrite to use FIXNUM_BITS, as this simplifies things.
1043 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1044 Adjust signatures to match updated version of code.
1045 (consing_since_gc): Now EMACS_INT, since a single hash table can
1046 use more than INT_MAX bytes.
1048 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1050 Make it possible to build with GCC-4.6+ -O2 -flto.
1052 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1054 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1056 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1057 Call minibuffer-inactive-mode.
1059 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1061 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1062 Update dependencies.
1064 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1066 * data.c (init_data): Remove code for UTS, this system is not
1069 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1071 Don't force ./temacs to start in terminal mode.
1073 * frame.c (make_initial_frame): Initialize faces in all cases, not
1074 only when CANNOT_DUMP is defined.
1075 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1077 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1079 * dispnew.c (add_window_display_history): Use const for the string
1080 pointer. Remove declaration, not needed.
1082 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1084 Use 'inline', not 'INLINE'.
1085 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1086 * alloc.c, fontset.c (INLINE): Remove.
1087 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1088 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1089 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1090 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1091 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1093 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1095 Make it possible to run ./temacs.
1097 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1098 syms_of_callproc does the same thing. Remove test for
1099 "initialized", do it in the caller.
1100 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1102 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1104 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1105 (read_minibuf): Use get_minibuffer.
1106 (syms_of_minibuf): Use DEFSYM.
1107 (Qmetadata): New var.
1108 * data.c (Qbuffer): Don't make it static.
1109 (syms_of_data): Use DEFSYM.
1111 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1113 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1114 (CCL_CODE_MIN): New macro.
1116 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1118 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1120 * eval.c (Qdebug): Now static.
1121 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1122 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1123 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1125 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1127 * image.c: Various fixes to ImageMagick code comments.
1128 (Fimagemagick_types): Doc fix.
1130 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1132 Minor fixes prompted by GCC 4.6.0 warnings.
1134 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1136 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1137 (x_clipboard_manager_save_all): Move extern decl to ...
1138 * xterm.h: ... here, so that it can be checked for consistency.
1140 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1142 * xselect.c (x_clipboard_manager_save_frame)
1143 (x_clipboard_manager_save_all): New functions.
1144 (Fx_clipboard_manager_save): Lisp function deleted.
1146 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1147 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1149 * xterm.h: Update prototype.
1151 2011-05-28 William Xu <william.xwl@gmail.com>
1153 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1156 2011-05-28 Jim Meyering <meyering@redhat.com>
1158 Avoid a sign-extension bug in crypto_hash_function.
1159 * fns.c (to_uchar): Define.
1160 (crypto_hash_function): Use it to convert some newly-signed
1161 variables to unsigned, to avoid sign-extension bugs. For example,
1162 without this change, (md5 "truc") would evaluate to
1163 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1164 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1165 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1167 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1169 Integer overflow fixes.
1171 * dbusbind.c: Serial number integer overflow fixes.
1172 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1173 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1174 to hold a serial number that is too large for a fixnum.
1175 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1176 Check for serial numbers out of range. Decode any serial number
1177 that was so large that it became a float. (Bug#8722)
1179 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1180 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1181 Use XFASTINT rather than XUINT when numbers are nonnegative.
1182 (xd_append_arg, Fdbus_method_return_internal):
1183 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1184 arguments, check that Lisp number is nonnegative, rather than
1185 silently wrapping negative numbers around. (Bug#8722)
1186 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1189 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1191 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1193 ccl: add integer overflow checks
1194 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1195 (IN_INT_RANGE): New macros.
1196 (ccl_driver): Use them to check for integer overflow when
1197 decoding a CCL program. Many of the new checks are whether XINT (x)
1198 fits in int; it doesn't always, on 64-bit hosts. The new version
1199 doesn't catch all possible integer overflows, but it's an
1200 improvement. (Bug#8719)
1202 * alloc.c (make_event_array): Use XINT, not XUINT.
1203 There's no need for unsigned here.
1205 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1206 This follows up to the 2011-05-06 change that substituted uintptr_t
1207 for EMACS_INT. This case wasn't caught back then.
1209 Rework Fformat to avoid integer overflow issues.
1210 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1211 now (part of C89). Include <verify.h>.
1212 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1213 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1214 (Fformat): Avoid the prepass trying to compute sizes; it was only
1215 approximate and thus did not catch overflow reliably. Instead, walk
1216 through the format just once, formatting and computing sizes as we go,
1217 checking for integer overflow at every step, and allocating a larger
1218 buffer as needed. Keep track separately whether the format is
1219 multibyte. Keep only the most-recently calculated precision, rather
1220 than them all. Record whether each argument has been converted to
1221 string. Use EMACS_INT, not int, for byte and char and arg counts.
1222 Support field widths and precisions larger than INT_MAX. Avoid
1223 sprintf's undefined behavior with conversion specifications such as %#d
1224 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1225 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1226 formatting out-of-range floating point numbers with int
1229 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1231 * data.c: Avoid integer truncation in expressions involving floats.
1232 * data.c: Include <intprops.h>.
1233 (arith_driver): When there's an integer overflow in an expression
1234 involving floating point, convert the integers to floating point
1235 so that the resulting value does not suffer from catastrophic
1236 integer truncation. For example, on a 64-bit host (* 4
1237 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1238 Do not rely on undefined behavior after integer overflow.
1240 merge count_size_as_multibyte, parse_str_to_multibyte
1241 * character.c, character.h (count_size_as_multibyte):
1242 Rename from parse_str_to_multibyte; all uses changed.
1243 Check for integer overflow.
1244 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1245 since it's now a duplicate of the other. This is more of
1246 a character than a buffer op, so better that it's in character.c.
1247 * fns.c, print.c: Adjust to above changes.
1249 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1251 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1253 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1255 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1256 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1257 (x_clipboard_manager_save): Now static.
1258 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1260 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1261 (crypto_hash_function): Now static.
1262 Fix pointer signedness problems. Avoid unnecessary initializations.
1264 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1266 * termhooks.h (Vselection_alist): Make it terminal-local.
1268 * terminal.c (create_terminal): Initialize it.
1270 * xselect.c: Support for clipboard managers.
1271 (Vselection_alist): Move to termhooks.h as terminal-local var.

1273 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1274 (symbol_to_x_atom): Remove gratuitous arg.
1275 (x_handle_selection_request, lisp_data_to_selection_data)
1276 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1277 (x_own_selection, x_get_local_selection, x_convert_selection):
1278 New arg, specifying work frame. Use terminal-local Vselection_alist.
1279 (some_frame_on_display): Delete unused function.
1280 (Fx_own_selection_internal, Fx_get_selection_internal)
1281 (Fx_disown_selection_internal, Fx_selection_owner_p)
1282 (Fx_selection_exists_p): New optional frame arg.
1283 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1284 (x_handle_selection_clear): Don't treat other terminals with the
1285 same keyboard specially. Use the terminal-local Vselection_alist.
1286 (x_clear_frame_selections): Use Frun_hook_with_args.
1288 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1290 * xterm.h: Add support for those atoms.
1292 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1294 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1295 (converted_selections, conversion_fail_tag): New global variables.
1296 (x_selection_request_lisp_error): Free the above.
1297 (x_get_local_selection): Remove unnecessary code.
1298 (x_reply_selection_request): Args changed; handle arbitrary array
1299 of converted selections stored in converted_selections.
1300 Separate the XChangeProperty and SelectionNotify steps.
1301 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1302 (x_convert_selection): New function.
1303 (x_handle_selection_event): Simplify.
1304 (x_get_foreign_selection): Don't ignore incoming requests while
1305 waiting for an answer; this will fail when we implement
1306 SAVE_TARGETS, and seems unnecessary anyway.
1307 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1308 (Vx_sent_selection_functions): Doc fix.
1310 2011-05-26 Leo Liu <sdl.web@gmail.com>
1312 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)

1319 for fringe update if it has periodic bitmap.
1320 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1321 and fringe_bitmap_periodic_p.
1323 * fringe.c (get_fringe_bitmap_data): New function.
1324 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1325 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1326 row. Mark glyph row for fringe update if periodicity changed.
1328 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1329 for fringe update unless it has periodic bitmap.
1331 2011-05-25 Kenichi Handa <handa@m17n.org>
1333 * xdisp.c (get_next_display_element): Set correct it->face_id for

1384 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1386 * systime.h (Time): Define only if emacs is defined.
1387 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1388 where the include path doesn't have X11/X.h by default. See
1389 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.

1426 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1428 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1430 Fix some integer overflow issues, such as string length overflow.
1432 * insdel.c (count_size_as_multibyte): Check for string overflow.
1434 * character.c (lisp_string_width): Check for string overflow.
1435 Use EMACS_INT, not int, for string indexes and lengths; in
1436 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1437 the resulting string length overflows an EMACS_INT; instead,
1438 report a string overflow if no precision given. When checking for
1439 precision exhaustion, use a check that cannot possibly have
1440 integer overflow. (Bug#8675)
1441 * character.h (lisp_string_width): Adjust to new signature.
1443 * alloc.c (string_overflow): New function.
1444 (Fmake_string): Use it. This doesn't change behavior, but saves
1445 a few bytes and will simplify future changes.
1446 * character.c (string_escape_byte8): Likewise.
1447 * lisp.h (string_overflow): New decl.
1449 Fixups, following up to the user-interface timestamp change.
1450 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1451 for UI timestamps, instead of unsigned long.
1452 * msdos.c (mouse_get_pos): Likewise.
1453 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1454 * w32gui.h (Time): Define by including "systime.h" rather than by
1455 declaring it ourselves. (Bug#8664)
1457 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1458 * image.c (clear_image_cache): Likewise.
1460 * term.c (term_mouse_position): Don't assume time_t wraparound.
1462 Be more systematic about user-interface timestamps.
1463 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1464 and sometimes 'EMACS_UINT', to represent these timestamps.
1465 This change causes it to use 'Time' uniformly, as that's what X uses.
1466 This makes the code easier to follow, and makes it easier to catch
1467 integer overflow bugs such as Bug#8664.
1468 * frame.c (Fmouse_position, Fmouse_pixel_position):
1469 Use Time, not unsigned long, for user-interface timestamps.
1470 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1471 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1472 * keyboard.h (last_event_timestamp): Likewise.
1473 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1474 * menu.h (xmenu_show): Likewise.
1475 * term.c (term_mouse_position): Likewise.
1476 * termhooks.h (struct input_event.timestamp): Likewise.
1477 (struct terminal.mouse_position_hook): Likewise.
1478 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1479 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1480 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1481 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1483 * menu.h, termhooks.h: Include "systime.h", for Time.
1485 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1486 Don't assume that the difference between two unsigned long values
1487 can fit into an integer. At this point, we know button_down_time
1488 <= event->timestamp, so the difference must be nonnegative, so
1489 there's no need to cast the result if double-click-time is
1490 nonnegative, as it should be; check that it's nonnegative, just in
1491 case. This bug is triggered when events are more than 2**31 ms
1492 apart (about 25 days). (Bug#8664)
1494 * xselect.c (last_event_timestamp): Remove duplicate decl.
1495 (x_own_selection): Remove needless cast to unsigned long.
1497 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1498 that always fit in int. Use a sentinel instead of a counter, to
1499 avoid a temp and to allay GCC's concerns about possible int overflow.
1500 * frame.h (struct frame): Use int for menu_bar_items_used
1501 instead of EMACS_INT, since it always fits in int.
1503 * menu.c (grow_menu_items): Check for int overflow.
1505 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1507 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1508 Before, the code was not consistent. These values cannot exceed
1509 2**31 - 1 so there's no need to make them unsigned.
1510 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1511 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1512 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1514 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1516 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1517 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1518 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1519 presumably because the widths might not match.
1521 * window.c (size_window): Avoid needless test at loop start.
1523 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1525 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1527 2011-05-12 Drew Adams <drew.adams@oracle.com>
1529 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1531 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1533 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1534 `width' to `bar_area_x' and `bar_area_width', respectively.
1535 (x_scroll_run): Take account of fringe background extension.
1537 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1538 Rename local vars `left' and `width' to `bar_area_x' and
1539 `bar_area_width', respectively.
1540 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1541 background extension.
1543 2011-05-10 Jim Meyering <meyering@redhat.com>
1545 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1547 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1549 * image.c (Finit_image_library): Return t for built-in image types,
1550 like pbm and xbm. (Bug#8640)
1552 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1554 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1556 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1558 * w32console.c (Fset_screen_color): Doc fix.
1559 (Fget_screen_color): New function.
1560 (syms_of_ntterm): Defsubr it.
1562 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1563 unlink the temporary file if Fcall_process didn't create it in the
1565 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1566 child process will be redirected to a file specified with `:file'.
1567 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1568 cue to call_process_cleanup not to close that handle.
1570 2011-05-07 Ben Key <bkey76@gmail.com>
1572 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1573 one of two shell specific rules, either bootstrap-temacs-CMD or
1574 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1575 to the previous implementation of the bootstrap-temacs rule.
1576 The bootstrap-temacs-CMD rule is similar to the previous
1577 implementation of the bootstrap-temacs rule except that it
1578 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1581 These changes, along with some changes to nt/configure.bat,
1582 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1583 earlier fix to add support for --cflags and --ldflags options
1584 that include quotes so that it works whether make uses cmd or
1587 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1589 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1590 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1592 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1593 a string. Handle both cases.
1594 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1595 (Fdbus_register_method): Use Qinvalid_function.
1597 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1599 * makefile.w32-in: Update dependencies.
1600 (LISP_H): Add inttypes.h and stdin.h.
1601 (PROCESS_H): Add unistd.h.
1603 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1605 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1606 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1608 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1610 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1612 * term.c (vfatal): Remove stray call to va_end.
1613 It's not needed and the C Standard doesn't allow it here anyway.
1615 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1616 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1618 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1621 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1623 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1625 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1627 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1629 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1631 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1632 * charset.c (Fdefine_charset_internal): Don't initialize
1633 charset.code_space[15]. The value was garbage, on hosts with
1634 32-bit int (Bug#8600).
1636 * lread.c (read_integer): Be more consistent with string-to-number.
1637 Use string_to_number to do the actual conversion; this avoids
1638 rounding errors and fixes some other screwups. Without this fix,
1639 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1640 (digit_to_number): Move earlier, for benefit of read_integer.
1641 Return -1 if the digit is out of range for the base, -2 if it is
1642 not a digit in any supported base. (Bug#8602)
1644 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1646 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1647 to match comment at start of function. This also removes a
1648 GCC warning about overflow in a 32+64-bit port.
1650 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1652 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1653 Reported by Stefan Monnier in
1654 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1655 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1656 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1658 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1659 (EMACS_UINTPTR): Likewise, with uintptr_t.
1661 * lisp.h: Prefer 64-bit EMACS_INT if available.
1662 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1663 on 32-bit hosts that have 64-bit int, so that they can access
1665 However, temporarily disable this change unless the temporary
1666 symbol WIDE_EMACS_INT is defined.
1668 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1670 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1671 This removes an assumption that EMACS_INT and long are the same
1672 width as pointers. The assumption is true for Emacs porting targets
1673 now, but we want to make other targets possible.
1674 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1675 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1676 In the rest of the code, change types of integers that hold casted
1677 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1678 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1679 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1680 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1681 No need to cast type when ORing.
1682 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1683 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1684 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1685 assume EMACS_INT is the same width as char *.
1686 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1687 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1688 Remove no-longer-needed casts.
1689 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1690 (xg_tool_bar_help_callback, xg_make_tool_item):
1691 Use EMACS_INTPTR to hold an integer
1692 that will be cast to void *; this can avoid a GCC warning
1693 if EMACS_INT is not the same width as void *.
1694 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1695 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1696 (current_message_1, set_message_1):
1697 Use a local to convert to proper width without a cast.
1698 * xmenu.c (dialog_selection_callback): Likewise.
1700 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1701 Also, don't assume VALBITS / RAND_BITS is less than 5,
1702 and don't rely on undefined behavior when shifting a 1 left into
1704 * lisp.h (get_random): Change signature to match.
1706 * lread.c (hash_string): Use size_t, not int, for hash computation.
1707 Normally we prefer signed values; but hashing is special, because
1708 it's better to use unsigned division on hash table sizes so that
1709 the remainder is nonnegative. Also, size_t is the natural width
1710 for hashing into memory. The previous code used 'int', which doesn't
1711 retain enough info to hash well into very large tables.
1712 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1714 * dbusbind.c: Don't possibly lose pointer info when converting.
1715 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1716 Use XPNTR rather than XHASH, so that the high-order bits of
1717 the pointer aren't lost when converting through void *.
1719 * eval.c (Fautoload): Don't double-shift a pointer.
1721 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1723 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1725 * gnutls.c (DEF_GNUTLS_FN):
1726 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1728 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1730 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
1733 2011-05-05 Eli Zaretskii <eliz@gnu.org>
1735 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
1736 New version that can reserve upto 2GB of heap space.
1738 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
1740 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
1742 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
1744 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
1745 `gnutls_certificate_set_x509_key_file'.
1747 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
1749 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
1750 Update dependencies.
1752 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1754 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
1755 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
1756 Remove unused parameter `fildes'.
1757 * process.c (read_process_output, send_process): Don't pass it.
1759 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1761 Fix previous change: the library cache is defined in w32.c.
1762 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
1763 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
1765 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1767 Implement dynamic loading of GnuTLS on Windows.
1769 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
1770 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
1771 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1774 * gnutls.c (Qgnutls_dll): Define.
1775 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
1776 (gnutls_*): Declare function pointers.
1777 (init_gnutls_functions): New function to initialize function pointers.
1778 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
1779 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
1780 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1781 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
1782 (emacs_gnutls_write, emacs_gnutls_read)
1783 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
1784 (Fgnutls_available_p): New function.
1785 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
1786 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
1787 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
1789 * image.c: Include w32.h.
1790 (Vimage_type_cache): Delete.
1791 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
1792 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
1793 (w32_delayed_load): Move to w32.c.
1795 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
1797 * w32.c (QCloaded_from, Vlibrary_cache): Define.
1798 (w32_delayed_load): Move from image.c. When loading a library, record
1799 its filename in the :loaded-from property of the library id.
1800 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
1801 Initialize and staticpro them.
1802 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
1804 * process.c: Include lisp.h before w32.h, not after.
1805 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
1806 instead of gnutls_record_check_pending.
1808 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
1810 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
1812 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
1813 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
1816 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
1818 * xterm.c (x_set_frame_alpha): Do not set property on anything
1819 else than FRAME_X_OUTER_WINDOW (Bug#8608).
1821 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
1823 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
1825 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
1827 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
1828 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
1829 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)
1830 (gnutls_global_initialized, Qgnutls_bootprop_priority)

1832 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
1833 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
1834 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
1835 (Qgnutls_bootprop_callbacks_verify): Make static.
1837 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
1839 * callproc.c: Indentation fixup.
1841 * sysdep.c (wait_for_termination_1): Make static.
1842 (wait_for_termination, interruptible_wait_for_termination):
1843 Move after wait_for_termination_1.
1845 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
1847 * sysdep.c (interruptible_wait_for_termination): New function
1848 which is like wait_for_termination, but allows keyboard
1851 * callproc.c (Fcall_process): Add (:file "file") as an option for
1853 (Fcall_process_region): Ditto.
1855 2011-04-30 Eli Zaretskii <eliz@gnu.org>
1857 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
1858 rather than `XVECTOR (FOO)->size'.
1860 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
1861 inttypes.h, as a gnulib replacement is used if it not available in

1866 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
1867 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
1868 of MOST_POSITIVE_FIXNUM. (Bug#8528)
1870 * coding.c (coding_alloc_by_realloc): Error out if destination
1871 will grow beyond MOST_POSITIVE_FIXNUM.
1872 (decode_coding_emacs_mule): Abort if there isn't enough place in
1873 charbuf for the composition carryover bytes. Reserve an extra
1874 space for up to 2 characters produced in a loop.
1875 (decode_coding_iso_2022): Abort if there isn't enough place in
1876 charbuf for the composition carryover bytes.
1878 2011-04-21 Eli Zaretskii <eliz@gnu.org>
1880 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
1881 aborting when %lld or %lll format is passed.
1882 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
1883 %llo or %llx format is passed. (Bug#8545)
1885 * window.c (window_scroll_line_based): Use a marker instead of
1886 simple variables to record original value of point. (Bug#7952)
1888 * doprnt.c (doprnt): Fix the case where a multibyte sequence
1889 produced by %s or %c overflows available buffer space. (Bug#8545)
1891 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
1893 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
1894 (SIZE_MAX): Move defn after all includes, as they might #define it.
1896 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1898 * w32.c (init_environment): Warn about defaulting HOME to C:\.
1900 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1902 * keyboard.c (Qdelayed_warnings_hook): Define.
1903 (command_loop_1): Run `delayed-warnings-hook'
1904 if Vdelayed_warnings_list is non-nil.
1905 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
1906 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
1908 2011-04-28 Eli Zaretskii <eliz@gnu.org>
1910 * doprnt.c (doprnt): Don't return value smaller than the buffer
1911 size if the message was truncated. (Bug#8545).
1913 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1915 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
1916 (Fx_window_property): #if-0 the whole functions, not just the bodies.
1918 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1920 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
1922 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
1924 * makefile.w32-in: Update dependencies.
1926 2011-04-27 Eli Zaretskii <eliz@gnu.org>
1928 Improve `doprnt' and its usage. (Bug#8545)
1929 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
1930 `format_end'. Remove support for %l as a conversion specifier.
1931 Don't use xrealloc. Improve diagnostics when the %l size modifier
1932 is used. Update the commentary.
1934 * eval.c (verror): Simplify calculation of size_t.
1936 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
1939 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
1941 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
1944 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1946 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
1947 This makes this file independent of the recent pseudovector change.
1949 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
1951 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
1953 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
1954 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
1955 Remove unused local.
1956 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
1958 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
1959 GCC 4.6.0 optimizes based on type-based alias analysis.
1960 For example, if b is of type struct buffer * and v of type struct
1961 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
1962 != &v->size, and therefore "v->size = 1; b->size = 2; return
1963 v->size;" must therefore return 1. This assumption is incorrect
1964 for Emacs, since it type-puns struct Lisp_Vector * with many other
1965 types. To fix this problem, this patch adds a new type struct
1966 vectorlike_header that documents the constraints on layout of vectors
1967 and pseudovectors, and helps optimizing compilers not get fooled
1968 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
1969 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
1970 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
1972 (XSETPVECTYPE): Rewrite in terms of new macro.
1973 (XSETPVECTYPESIZE): New macro, specifying both type and size.
1974 This is a bit clearer, and further avoids the possibility of
1975 undesirable aliasing.
1976 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
1977 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
1978 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
1979 since Lisp_Subr is a special case (no "next" field).
1980 (ASIZE): Now uses header.size rather than size.
1981 All previous uses of XVECTOR (foo)->size replaced to use this macro,
1982 to avoid the hassle of writing XVECTOR (foo)->header.size.
1983 (struct vectorlike_header): New type.
1984 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
1985 object, to help avoid aliasing.
1986 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
1987 (SUBRP): Likewise, since Lisp_Subr is a special case.
1988 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
1989 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
1990 (struct Lisp_Hash_Table): Combine first two members into a single
1991 struct vectorlike_header member. All uses of "size" and "next" members
1992 changed to be "header.size" and "header.next".
1993 * buffer.h (struct buffer): Likewise.
1994 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
1995 * frame.h (struct frame): Likewise.
1996 * process.h (struct Lisp_Process): Likewise.
1997 * termhooks.h (struct terminal): Likewise.
1998 * window.c (struct save_window_data, struct saved_window): Likewise.
1999 * window.h (struct window): Likewise.
2000 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2001 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2002 * buffer.c (init_buffer_once): Likewise.
2003 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2005 * process.c (Fformat_network_address): Use local var for size,
2008 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2010 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2011 * data.c (atof): Remove decl; no longer used or needed.
2012 (digit_to_number): Move to lread.c.
2013 (Fstring_to_number): Use new string_to_number function, to be
2014 consistent with how the Lisp reader treats infinities and NaNs.
2015 Do not assume that floating-point numbers represent EMACS_INT
2016 without losing information; this is not true on most 64-bit hosts.
2017 Avoid double-rounding errors, by insisting on integers when
2018 parsing non-base-10 numbers, as the documentation specifies.
2019 * lisp.h (string_to_number): New decl, replacing ...
2020 (isfloat_string): Remove.
2021 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2022 (read1): Do not accept +. and -. as integers; this
2023 appears to have been a coding error. Similarly, do not accept
2024 strings like +-1e0 as floating point numbers. Do not report
2025 overflow for integer overflows unless the base is not 10 which
2026 means we have no simple and reliable way to continue.
2027 Break out the floating-point parsing into a new
2028 function string_to_number, so that Fstring_to_number parses
2029 floating point numbers consistently with the Lisp reader.
2030 (digit_to_number): Move here from data.c. Make it static inline.
2031 (E_CHAR, EXP_INT): Remove, replacing with ...
2032 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2033 (string_to_number): New function, replacing isfloat_string.
2034 This function checks for valid syntax and produces the resulting
2035 Lisp float number too. Rework it so that string-to-number
2036 no longer mishandles examples like "1.0e+". Use strtoumax,
2037 so that overflow for non-base-10 numbers is reported only when
2038 there's no portable and simple way to convert to floating point.
2040 * textprop.c (set_text_properties_1): Rewrite for clarity,
2041 and to avoid GCC warning about integer overflow.
2043 * intervals.h (struct interval): Use EMACS_INT for members
2044 where EMACS_UINT might cause problems. See
2045 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2046 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2047 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2049 (offset_intervals): Tell GCC not to worry about length overflow
2050 when negating a negative length.
2052 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2053 (overrun_check_free): Likewise.
2055 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2056 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2059 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2060 (gnutls_make_error): Rename local to avoid shadowing.
2061 (gnutls_emacs_global_deinit): ifdef out; not used.
2062 (Fgnutls_boot): Use const for pointer to readonly storage.
2063 Comment out unused local. Fix pointer signedness problems.
2065 * lread.c (openp): Don't stuff size_t into an 'int'.
2066 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2067 about possible signed overflow.
2069 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2070 (GDK_KEY_g): Don't define if already defined.
2071 (xg_prepare_tooltip): Avoid pointer signedness problem.
2072 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2074 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2075 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2077 * xfns.c (Fx_window_property): Simplify a bit,
2078 to make a bit faster and to avoid GCC 4.6.0 warning.
2079 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2081 * fns.c (internal_equal): Don't assume size_t fits in int.
2083 * alloc.c (compact_small_strings): Tighten assertion a little.
2085 Replace pEd with more-general pI, and fix some printf arg casts.
2086 * lisp.h (pI): New macro, generalizing old pEd macro to other
2087 conversion specifiers. For example, use "...%"pI"d..." rather
2088 than "...%"pEd"...".
2089 (pEd): Remove. All uses replaced with similar uses of pI.
2090 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2091 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2092 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2093 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2094 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2095 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2096 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2098 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2099 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2100 * print.c (safe_debug_print, print_object): Likewise.
2101 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2103 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2104 avoiding the 0 flag, which is not portable.
2105 * process.c (Fmake_network_process): Use pI to avoid cast.
2106 * region-cache.c (pp_cache): Likewise.
2107 * xdisp.c (decode_mode_spec): Likewise.
2108 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2109 behavior on 64-bit hosts with printf arg.
2110 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2111 (x_stop_queuing_selection_requests): Likewise.
2112 (x_get_window_property): Don't truncate byte count to an 'int'
2115 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2116 here, since it parses constructs like leading '-' and spaces,
2117 which are not wanted; and it overflows with large numbers.
2118 Instead, simply match F[0-9]+, which is what is wanted anyway.
2120 * alloc.c: Remove unportable assumptions about struct layout.
2121 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2122 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2123 (allocate_vectorlike, make_pure_vector): Use the new macros,
2124 plus offsetof, to remove unportable assumptions about struct layout.
2125 These assumptions hold on all porting targets that I know of, but
2126 they are not guaranteed, they're easy to remove, and removing them
2127 makes further changes easier.
2129 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2130 This doesn't fix a bug but makes the code clearer.
2131 (string_overrun_cookie): Now const. Use initializers that
2132 don't formally overflow signed char, to avoid warnings.
2133 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2134 can cause Emacs to crash when string overrun checking is enabled.
2135 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2136 multiple of sizeof (EMACS_INT); it need not be, if
2137 alignof(EMACS_INT) < sizeof (EMACS_INT).
2138 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2140 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2142 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
2144 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
2146 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
2147 supposed to be handshaking. (Bug#8556)
2148 Reported by Paul Eggert <eggert@cs.ucla.edu>.
2150 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

2153 * eval.c (Qdebug): Restore global linkage.
2154 * keyboard.c (debug-on-event): New variable.
2155 (handle_user_signal): Break into debugger when debug-on-event
2156 matches the current signal symbol.

2160 * alloc.c (check_sblock, check_string_bytes)
2161 (check_string_free_list): Convert to standard C.
2163 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2165 * w32.c (emacs_gnutls_push): Fix typo.
2167 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2169 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2170 "cast to pointer from integer of different size".
2172 Improve doprnt and its use in verror. (Bug#8545)
2173 * doprnt.c (doprnt): Document the set of format control sequences
2174 supported by the function. Use SAFE_ALLOCA instead of always
2177 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2178 is one byte too soon. Don't use xrealloc; instead xfree and
2181 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2183 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2186 * gnutls.c: Renamed global_initialized to
2187 gnutls_global_initialized. Added internals for the
2188 :verify-hostname-error, :verify-error, and :verify-flags
2189 parameters of `gnutls-boot' and documented those parameters in the
2190 docstring. Start callback support.
2191 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2192 unless a fatal error occured. Call gnutls_alert_send_appropriate
2193 on error. Return error code.
2194 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
2195 (emacs_gnutls_read): Likewise.
2196 (Fgnutls_boot): Return handshake error code.
2197 (emacs_gnutls_handle_error): New function.
2198 (wsaerror_to_errno): Likewise.
2200 * w32.h (emacs_gnutls_pull): Add prototype.
2201 (emacs_gnutls_push): Likewise.

2208 * process.c (wait_reading_process_output): Check if GnuTLS
2209 buffered some data internally if no FDs are set for TLS

2265 * doprnt.c: Include limits.h.
2266 (SIZE_MAX): New macro.
2267 (doprnt): Return a size_t value. 2nd arg is now size_t.
2268 Many local variables are now size_t instead of int or unsigned.
2269 Improve overflow protection. Support `l' modifier for integer
2270 conversions. Support %l conversion. Don't assume an EMACS_INT
2271 argument for integer conversions and for %c.
2273 * lisp.h (doprnt): Restore prototype.
2275 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
2278 * Makefile.in (base_obj): Add back doprnt.o.
2280 * deps.mk (doprnt.o): Add back prerequisites.
2281 (callint.o): Depend on character.h.
2283 * eval.c (internal_lisp_condition_case): Include the handler
2284 representation in the error message.
2285 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
2286 when breaking from the loop.
2288 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
2290 * callint.c (Fcall_interactively): When displaying error message
2291 about invalid control letter, pass the character's codepoint, not
2292 a pointer to its multibyte form. Improve display of the character
2293 in octal and display also its hex code.
2295 * character.c (char_string): Use %x to display the (unsigned)
2296 codepoint of an invalid character, to avoid displaying a bogus
2299 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
2300 `error', not SYMBOL_NAME itself.
2302 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
2303 character arguments to `error'.
2305 * charset.c (check_iso_charset_parameter): Fix incorrect argument
2306 to `error' in error message about FINAL_CHAR argument. Make sure
2307 FINAL_CHAR is a character, and use %c when it is passed as
2308 argument to `error'.
2310 2011-04-23 Eli Zaretskii <eliz@gnu.org>
2312 * s/ms-w32.h (localtime): Redirect to sys_localtime.
2314 * w32.c: Include <time.h>.

2372 Define only if needed.
2374 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

2857 so that it's not optimized away.
2858 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
2859 * dispextern.h (bidi_dump_cached_states): Remove, since it's
2860 exported only to the debugger.
2862 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
2863 * atimer.h (run_all_atimers): Remove; not exported.
2865 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
2866 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
2867 was inaccessible from Lisp.
2868 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
2869 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
2871 alloc.c: Import and export fewer symbols, and remove unused items.
2872 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
2874 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
2875 it's not optimized away by whole-program optimization.

2888 (mark_backtrace): Define only if BYTE_MARK_STACK.
2889 * xdisp.c (message_enable_multibyte): Now static.
2891 Declare Lisp_Object Q* variables to be 'static' if not exported.
2892 This makes it easier for human readers (and static analyzers)
2893 to see whether these variables are used from other modules.
2894 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
2895 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
2896 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

2904 Remove decls of unexported vars.
2905 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
2907 * lisp.h (DEFINE_FUNC): Make sname 'static'.
2909 Make Emacs functions such as Fatom 'static' by default.
2910 This makes it easier for human readers (and static analyzers)
2911 to see whether these functions can be called from other modules.
2912 DEFUN now defines a static function. To make the function external
2913 so that it can be used in other C modules, use the new macro DEFUE.
2914 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
2915 (Finit_image_library):
2916 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
2917 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
2918 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
2919 Remove decls, since these functions are now static.
2920 (Funintern, Fget_internal_run_time): New decls, since these functions
2921 were already external.

2930 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
2931 Mark functions with DEFUE instead of DEFUN,
2932 if they are used in other modules.

2974 when at ZV. (Bug#8487)
2976 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
2978 * charset.c (Fclear_charset_maps): Use xfree instead of free.
2980 * keyboard.c (parse_tool_bar_item): Likewise.
2981 * sound.c (sound_cleanup, alsa_close): Likewise.
2982 * termcap.c (tgetent): Likewise.
2983 * xfns.c (x_default_font_parameter): Likewise.
2984 * xsettings.c (read_and_apply_settings): Likewise.
2986 * alloc.c (overrun_check_malloc, overrun_check_realloc)
2987 (overrun_check_free): Protoize.
2989 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
2991 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
2992 since callers should never pass a negative size.
2993 Change the signature to match that of plain 'read' and 'write'; see
2994 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
2995 * lisp.h: Update prototypes of emacs_write and emacs_read.
2997 2011-04-11 Eli Zaretskii <eliz@gnu.org>
2999 * xdisp.c (redisplay_window): Don't try to determine the character
3000 position of the scroll margin if the window start point w->startp
3001 is outside the buffer's accessible region. (Bug#8468)
3003 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3005 Fix write-region and its subroutines for buffers > 2GB.
3006 * fileio.c (a_write, e_write): Modify declaration of arguments and
3007 local variables to support buffers larger than 2GB.
3008 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3010 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3011 argument, local variables, and return value.
3013 * lisp.h: Update prototypes of emacs_write and emacs_read.
3015 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3017 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3019 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3021 Fix more problems found by GCC 4.6.0's static checks.
3023 * xdisp.c (vmessage): Use a better test for character truncation.
3025 * charset.c (load_charset_map): <, not <=, for optimization,
3026 and to avoid potential problems with integer overflow.
3027 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3028 * casetab.c (set_identity, shuffle): Likewise.
3029 * editfns.c (Fformat): Likewise.
3030 * syntax.c (skip_chars): Likewise.
3032 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3033 This also lets GCC 4.6.0 generate slightly better loop code.
3035 * callint.c (Fcall_interactively): <, not <=, for optimization.
3036 (Fcall_interactively): Count the number of arguments produced,
3037 not the number of arguments given. This is simpler and lets GCC
3038 4.6.0 generate slightly better code.
3040 * ftfont.c: Distingish more carefully between FcChar8 and char.
3041 The previous code passed unsigned char * to a functions like
3042 strlen and xstrcasecmp that expect char *, which does not
3043 conform to the C standard.
3044 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3045 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3046 char * when the C standard requires it.
3048 * keyboard.c (read_char): Remove unused var.
3050 * eval.c: Port to Windows vsnprintf (Bug#8435).
3052 (SIZE_MAX): Define if the headers do not.
3053 (verror): Do not give up if vsnprintf returns a negative count.
3054 Instead, grow the buffer. This ports to Windows vsnprintf, which
3055 does not conform to C99. Problem reported by Eli Zaretskii.
3056 Also, simplify the allocation scheme, by avoiding the need for
3057 calling realloc, and removing the ALLOCATED variable.
3059 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3061 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3062 But keep the doprint source code for now, as we might revamp it
3063 and use it again (Bug#8435).
3064 * lisp.h (doprnt): Remove.
3065 * Makefile.in (base_obj): Remove doprnt.o.
3066 * deps.mk (doprnt.o): Remove.
3068 error: Print 32- and 64-bit integers portably (Bug#8435).
3069 Without this change, on typical 64-bit hosts error ("...%d...", N)
3070 was used to print both 32- and 64-bit integers N, which relied on
3072 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3074 * lisp.h (error, verror): Mark as printf-like functions.
3075 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3076 Report overflow in size calculations when allocating printf buffer.
3077 Do not truncate output string at its first null byte.
3078 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3079 Truncate the output at a character boundary, since vsnprintf does not
3081 * charset.c (check_iso_charset_parameter): Convert internal
3082 character to string before calling 'error', since %c now has the
3084 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3085 overflow when computing char to be passed to 'error'. Do not
3086 pass Lisp_Object to 'error'; pass the integer instead.
3087 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3088 formatted with plain %d.
3090 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3092 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3094 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3096 * xterm.c (x_catch_errors): Remove duplicate declaration.
3098 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3100 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3102 2011-04-10 Jim Meyering <meyering@redhat.com>
3104 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3105 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3106 return ssize_t not "int", and use size_t as the buffer length.
3107 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3108 * gnutls.h: Update declarations.
3109 * process.c (read_process_output): Use ssize_t, to match.
3110 (send_process): Likewise.
3112 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3114 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3116 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3118 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3119 Use unsigned char, to match FcChar8 type definition.
3121 * xterm.c (handle_one_xevent):
3122 * xmenu.c (create_and_show_popup_menu):
3123 * xselect.c (x_decline_selection_request)
3124 (x_reply_selection_request): Avoid type-punned deref of X events.
3126 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3128 Fix some uses of `int' instead of EMACS_INT.
3129 * search.c (string_match_1, fast_string_match)
3130 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3131 (scan_buffer, find_next_newline_no_quit)
3132 (find_before_next_newline, search_command, Freplace_match)
3133 (Fmatch_data): Make some `int' variables be EMACS_INT.
3135 * xdisp.c (display_count_lines): 3rd argument and return value now
3136 EMACS_INT. All callers changed.
3137 (pint2hrstr): Last argument is now EMACS_INT.
3139 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3140 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3141 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

3144 (decode_coding_ccl, decode_coding_charset)
3145 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

3147 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
3148 <char_offset, last_offset>: Declare EMACS_INT.

3153 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3155 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3156 (encode_invocation_designation): Last argument P_NCHARS is now
3158 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3159 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
3161 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
3164 * ccl.c (Fccl_execute_on_string): Declare some variables
3167 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

3179 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3181 * keyboard.c (read_char): Call Lisp function help-form-show,
3182 instead of using internal_with_output_to_temp_buffer.

3184 (syms_of_keyboard): Use DEFSYM macro.
3186 * print.c (internal_with_output_to_temp_buffer): Function deleted.

3199 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3201 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3203 Fix more problems found by GCC 4.6.0's static checks.
3205 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3207 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3209 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
3211 * xdisp.c (vmessage): Mark as a printf-like function.
3213 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
3215 * sound.c (sound_warning): Don't crash if arg contains a printf format.
3217 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
3218 printf-like functions.
3219 (tiff_load): Add casts to remove these marks before passing them
3220 to system-supplied API.
3222 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3224 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3225 This avoids several warnings with gcc -Wstrict-overflow.
3226 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3227 directly, rather than having caller test rule sign. This avoids
3228 some unnecessary tests.
3229 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3230 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3231 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

3245 by using the new macro.
3247 * textprop.c (set_text_properties_1): Change while to do-while,
3248 since the condition is always true at first.

3251 (interval_deletion_adjustment): Return unsigned value.
3254 * process.c (list_processes_1, create_pty, read_process_output):

3283 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3284 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3285 can always succeed if overflow has undefined behavior.
3287 * search.c (boyer_moore, wordify): Remove vars set but not used.
3288 (wordify): Omit three unnecessary tests.
3290 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3291 All callers changed. This avoids the need for an unused var.
3293 * casefiddle.c (casify_region): Remove var that is set but not used.
3295 * dired.c (file_name_completion): Remove var that is set but not used.
3297 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3299 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3300 (Finsert_file_contents): Remove unnecessary code checking fd.
3302 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3303 Check for integer overflow on size calculations.

3315 * image.c (lookup_image): Remove var that is set but not used.
3316 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3318 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3319 that are set but not used.
3321 * xfns.c (make_invisible_cursor): Don't return garbage
3322 if XCreateBitmapFromData fails (Bug#8410).
3324 * xselect.c (x_get_local_selection, x_handle_property_notify):
3325 Remove vars that are set but not used.
3327 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3328 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3330 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3331 Remove var that is set but not used.
3332 (scroll_bar_windows_size): Now size_t, not int.
3333 (x_send_scroll_bar_event): Use size_t, not int, for sizes.

3342 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3343 All callers changed.
3344 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3345 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3346 (decode_coding_charset): Remove vars that are set but not used.
3348 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3349 that is set but not used.
3351 * print.c (print_object): Remove var that is set but not used.
3353 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3354 The gnulib version avoids calling malloc in the usual case,
3355 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3356 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3357 * filelock.c (current_lock_owner): Likewise.
3358 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3359 * sysdep.c: Include allocator.h, careadlinkat.h.
3360 (emacs_no_realloc_allocator): New static constant.
3361 (emacs_readlink): New function.
3362 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

3367 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3368 first non-nil return value).

3382 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3383 and thereabouts. All callers changed.
3384 (get_per_char_metric): Remove parameter `f', unused since
3385 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3390 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3391 (ns_get_family): Likewise.
3393 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

3397 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3399 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3402 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3404 Add lexical binding.
3406 * window.c (Ftemp_output_buffer_show): New fun.
3407 (Fsave_window_excursion):
3408 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3410 * lread.c (lisp_file_lexically_bound_p): New function.
3411 (Fload): Bind Qlexical_binding.
3412 (readevalloop): Remove `evalfun' arg.
3413 Bind Qinternal_interpreter_environment.
3414 (Feval_buffer): Bind Qlexical_binding.
3415 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3417 (syms_of_lread): Declare `lexical-binding'.
3419 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3421 * keyboard.c (eval_dyn): New fun.
3422 (menu_item_eval_property): Use it.
3424 * image.c (parse_image_spec): Use Ffunctionp.
3426 * fns.c (concat, mapcar1): Accept byte-code-functions.
3428 * eval.c (Fsetq): Handle lexical vars.
3429 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3430 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3431 (FletX, Flet): Obey lexical binding.
3432 (Fcommandp): Handle closures.
3433 (Feval): New `lexical' arg.
3434 (eval_sub): New function extracted from Feval. Use it almost
3435 everywhere where Feval was used. Look up vars in lexical env.
3437 (Ffunctionp): Move from subr.el.
3438 (Ffuncall): Handle closures.
3439 (apply_lambda): Remove `eval_flags'.
3440 (funcall_lambda): Handle closures and new byte-code-functions.
3441 (Fspecial_variable_p): New function.
3442 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3443 but without exporting it to Lisp.
3445 * doc.c (Fdocumentation, store_function_docstring):
3446 * data.c (Finteractive_form): Handle closures.
3448 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3451 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3453 (exec_byte_code): New function extracted from Fbyte_code to handle new
3454 calling convention for byte-code-functions. Add new byte-codes.
3456 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3458 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3460 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3462 * xdisp.c (redisplay_internal): Fix prototype.
3464 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3466 * xdisp.c (SCROLL_LIMIT): New macro.
3467 (try_scrolling): Use it when setting scroll_limit.
3468 Limit scrolling to 100 screen lines.
3469 (redisplay_window): Even when falling back on "recentering",
3470 position point in the window according to scroll-conservatively,
3471 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3473 (try_scrolling): When point is above the window, allow searching
3474 as far as scroll_max, or one screenful, to compute vertical
3475 distance from PT to the scroll margin position. This prevents
3476 try_scrolling from unnecessarily failing when
3477 scroll-conservatively is set to a value slightly larger than the
3478 window height. Clean up the case of PT below the margin at bottom
3479 of window: scroll_max can no longer be INT_MAX. When aggressive
3480 scrolling is in use, don't let point enter the opposite scroll
3481 margin as result of the scroll.
3482 (syms_of_xdisp) <scroll-conservatively>: Document the
3483 threshold of 100 lines for never-recentering scrolling.

3490 (message_log_check_duplicate): Remove parameters `prev_bol' and
3491 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3492 (redisplay_internal): Remove parameter `preserve_echo_area',
3493 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3495 * indent.c (Fvertical_motion):
3496 * window.c (window_scroll_pixel_based, Frecenter):
3497 Don't pass `need_y_p' to `move_it_by_lines'.
3499 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3501 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3502 steal a few bits to be more compact.
3503 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3504 Remove unneeded casts.
3506 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3508 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3510 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3511 binding" message (bug#7967).
3513 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3515 Fix more problems found by GCC 4.6.0's static checks.
3517 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3518 Remove unused local var.
3520 * editfns.c (Fmessage_box): Remove unused local var.
3522 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3523 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3524 Omit unused local vars.
3525 * window.c (shrink_windows): Omit unused local var.
3526 * menu.c (digest_single_submenu): Omit unused local var.
3527 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3528 Omit unused local var.
3530 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3531 Don't assume string length fits in int.
3532 (keyremap_step, read_key_sequence): Use size_t for sizes.
3533 (read_key_sequence): Don't check last_real_key_start redundantly.
3535 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3536 instead of alloca (Bug#8344).
3538 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3539 (Fbacktrace_frame): Don't assume nframes fits in int.
3541 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3543 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3546 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3548 * cm.c (calccost): Turn while-do into do-while, for clarity.
3550 * keyboard.c (syms_of_keyboard): Use the same style as later
3551 in this function when indexing through an array. This also
3552 works around GCC bug 48267.
3554 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3556 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3558 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3559 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3561 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3562 This avoids undefined behavior on integer overflow, and is a bit
3563 more convenient anyway since it is compared to a size_t variable.
3565 Variadic C functions now count arguments with size_t, not int.
3566 This avoids an unnecessary limitation on 64-bit machines, which
3567 caused (substring ...) to crash on large vectors (Bug#8344).
3568 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

3578 * frame.c (x_set_frame_parameters): Likewise.
3579 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3580 0 if not found, not -1. All callers changed.
3582 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3583 (stack_copy_size): Now size_t, not int.
3584 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3586 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3588 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3589 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3590 All callers changed.
3592 * lisp.h (multibyte_char_to_unibyte):
3593 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
3594 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

3605 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
3606 don't set the hook to nil, but remove the offending function instead.
3607 (Qcommand_hook_internal): Remove, unused.
3608 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
3609 Vcommand_hook_internal.
3611 * eval.c (enum run_hooks_condition): Remove.
3612 (funcall_nil, funcall_not): New functions.
3613 (run_hook_with_args): Call each function through a `funcall' argument.

3628 All callers changed.
3630 * w32.c (_wsa_errlist): Use braces for struct initializers.
3632 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
3633 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
3634 All callers changed.

3777 2011-03-23 Julien Danjou <julien@danjou.info>
3779 * term.c (Fsuspend_tty, Fresume_tty):
3780 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
3781 * window.c (temp_output_buffer_show):
3782 * insdel.c (signal_before_change):
3783 * frame.c (Fhandle_switch_frame):
3784 * fileio.c (Fdo_auto_save):
3785 * emacs.c (Fkill_emacs):
3786 * editfns.c (save_excursion_restore):
3787 * cmds.c (internal_self_insert):
3788 * callint.c (Fcall_interactively):
3789 * buffer.c (Fkill_all_local_variables):
3790 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3792 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3793 unconditionnaly since it does the check itself.
3795 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3797 Fix more problems found by GCC 4.5.2's static checks.
3799 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3800 the first time through the loop, since we know p0 < p1 then.
3801 This also avoids a gcc -Wstrict-overflow warning.
3803 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3804 leading to a memory leak, possible in functions like
3805 load_charset_map_from_file that can allocate an unbounded number
3806 of objects (Bug#8318).
3808 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3809 that could (at least in theory) be that large.
3811 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3812 This is less likely to overflow, and avoids undefined behavior if
3813 overflow does occur. All callers changed. Use strtoul to scan
3814 for the unsigned long integer.
3815 (pint2hrstr): Simplify and tune code slightly.
3816 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
3818 * scroll.c (do_scrolling): Work around GCC bug 48228.
3819 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

3824 This also avoids a warning with gcc -Wstrict-overflow.
3826 * fileio.c (Fcopy_file): Report error if fchown or fchmod
3829 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
3831 * process.c (Fmake_network_process): Use socklen_t, not int,
3832 where POSIX says socklen_t is required in portable programs.
3833 This fixes a porting bug on hosts like 64-bit HP-UX, where
3834 socklen_t is wider than int (Bug#8277).
3835 (Fmake_network_process, server_accept_connection):
3836 (wait_reading_process_output, read_process_output):
3839 * process.c: Rename or move locals to avoid shadowing.

3849 Make tparam.h and terminfo.c consistent.
3850 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
3851 Include tparam.h instead, since it declares them.
3852 * cm.h (PC): Remove extern decl; tparam.h now does this.
3853 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3854 * terminfo.c: Include tparam.h, to check interfaces.
3855 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3856 (tparam): Adjust signature to match interface in tparam.h;
3857 this removes some undefined behavior. Check that outstring and len
3858 are zero, which they always are with Emacs.
3859 * tparam.h (PC, BC, UP): New extern decls.
3861 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3862 (xftfont_open): Rename locals to avoid shadowing.
3864 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

3880 (composition_update_it): Mark var as initialized.
3881 (find_automatic_composition): Mark vars as initialized,
3882 with a FIXME (Bug#8290).
3884 character.h: Rename locals to avoid shadowing.

3886 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
3887 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
3888 (BUF_DEC_POS): Be more systematic about renaming local temporaries
3891 * textprop.c (property_change_between_p): Remove; unused.
3893 * intervals.c (interval_start_pos): Now static.
3895 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

3898 Rename locals to avoid shadowing.
3900 * sound.c (wav_play, au_play, Fplay_sound_internal):
3901 Fix pointer signedness.
3902 (alsa_choose_format): Remove unused local var.
3903 (wav_play): Initialize a variable to 0, to prevent undefined
3904 behavior (Bug#8278).
3906 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
3908 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
3910 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
3911 clobbering (Bug#8298).
3912 * sysdep.c (sys_subshell): Likewise.
3913 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
3915 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
3916 This should get cleaned up, so that child_setup has the
3917 same signature on all platforms.
3919 * callproc.c (call_process_cleanup): Now static.
3920 (relocate_fd): Rename locals to avoid shadowing.
3922 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
3924 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
3925 not to be necessary, and produces flickering.
3927 2011-03-20 Glenn Morris <rgm@gnu.org>
3929 * config.in: Remove file.
3931 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
3933 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
3934 are now in src/globals.h.
3935 (syms_of_minibuf): Remove spurious & from previous change.
3937 2011-03-20 Leo <sdl.web@gmail.com>
3939 * minibuf.c (completing-read-function): New variable.
3940 (completing-read-default): Rename from completing-read.
3941 (completing-read): Call completing-read-function.
3943 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3945 * xfaces.c (Fx_load_color_file):
3946 Read color file from absolute filename (bug#8250).
3948 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
3950 * makefile.w32-in: Update dependencies.
3952 2011-03-17 Eli Zaretskii <eliz@gnu.org>
3954 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

3961 (sigchld_handler): Now static.
3963 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
3964 That way, the code declares only the vars that it needs.
3965 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
3966 * s/cygwin.h (PTY_ITERATION): Likewise.
3967 * s/darwin.h (PTY_ITERATION): Likewise.

3970 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
3971 * process.c (allocate_pty): Don't declare stb unless it's needed.
3973 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
3974 (CONSTANTLIM): Remove; unused.
3975 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
3976 Define only if needed.
3978 * unexelf.c (unexec): Name an expression,
3979 to avoid gcc -Wbad-function-cast warning.
3980 Use a different way to cause a compilation error if anyone uses
3981 n rather than nn, a way that does not involve shadowing.
3982 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
3984 * deps.mk (unexalpha.o): Remove; unused.
3986 New file unexec.h, the (simple) interface for unexec (Bug#8267).
3987 * unexec.h: New file.
3988 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
3989 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
3991 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
3992 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
3993 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

3998 (back_comment, skip_chars): Mark vars as initialized.
4000 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):
4001 Rename locals to avoid shadowing.
4003 * lread.c (read1): Rewrite so as not to use empty "else".
4004 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
4006 * print.c (Fredirect_debugging_output): Fix pointer signedess.
4008 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
4009 warning when compiling print.c.
4011 * font.c (font_unparse_fcname): Abort in an "impossible" situation
4012 instead of using an uninitialized var.
4013 (font_sort_entities): Mark var as initialized.

4049 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4050 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4051 some of which prompt warnings from gcc -Wbad-function-cast.
4052 (Fformat_time_string, Fencode_time, Finsert_char):

4064 gcc -Wbad-function-cast warning.
4065 (default_value, arithcompare, arith_driver, arith_error): Now static.

4072 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4073 Rename locals to avoid shadowing.
4074 (mark_stack): Move local variables into the #ifdef region where
4076 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4077 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4079 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4080 (GC_STRING_CHARS): Remove; not used.
4081 (Fmemory_limit): Cast sbrk's returned value to char *.
4083 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4084 avoids undefined behavior in theory.
4086 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4088 Use functions, not macros, for up- and down-casing (Bug#8254).
4089 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4090 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4091 to use the following functions instead of these macros.
4092 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4093 EMACS_INT, since callers assume the returned value fits in int.
4094 (upcase1): Likewise, for UPCASE_TABLE.
4095 (uppercasep, lowercasep, upcase): New static inline functions.
4096 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

4100 Rename locals to avoid shadowing.
4101 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4102 (regex_compile, re_search_2, re_match_2_internal):
4103 Remove unused local vars.
4104 (FREE_VAR): Rewrite so as not to use empty "else",
4105 which gcc can warn about.
4106 (regex_compile, re_match_2_internal): Mark locals as initialized.
4107 (RETALLOC_IF): Define only if needed.
4108 (WORDCHAR_P): Likewise. This one is never needed, but is used
4109 only in a comment talking about a compiler bug, so put inside
4110 the #if 0 of that comment.
4111 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4112 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4115 * search.c (boyer_moore): Rename locals to avoid shadowing.
4116 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4117 (PREV_CHAR_BOUNDARY): Likewise.
4119 * search.c (simple_search): Remove unused var.
4121 * dired.c (compile_pattern): Move decl from here ...

4125 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
4127 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
4129 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
4130 Rename locals to avoid shadowing.
4131 (Fvertical_motion): Mark locals as initialized.
4133 * casefiddle.c (casify_object, casify_region): Now static.
4134 (casify_region): Mark local as initialized.
4136 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4138 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4139 New macros, so that the caller can use some names other than
4140 gcpro1, gcpro2, etc.
4141 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4143 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4144 argument, for consistency with GCPRO2_VAR, etc: it is now the
4145 prefix of the variable, not the variable itself. All uses
4147 * dired.c (directory_files_internal, file_name_completion):
4148 Rename locals to avoid shadowing.
4150 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4151 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4152 dired.c's scmp function, had undefined behavior.
4153 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4154 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4155 * buffer.h: ... to here, because these macros use current_buffer,
4156 and the new implementation with inline functions needs to have
4157 current_buffer in scope now, rather than later when the macros
4159 (downcase, upcase1): New static inline functions.
4160 (DOWNCASE, UPCASE1): Reimplement using these functions.
4161 This avoids undefined behavior in expressions like
4162 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4163 from race conditions in accessing the global variables
4164 case_temp1 and case_temp2.
4165 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4166 * lisp.h (case_temp1, case_temp2): Remove their decls.
4167 * character.h (ASCII_CHAR_P): Move from here ...
4168 * lisp.h: ... to here, so that the inline functions mentioned
4171 * dired.c (directory_files_internal_unwind): Now static.
4173 * fileio.c (file_name_as_directory, directory_file_name):
4174 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4176 (file_name_as_directory): Use const pointers when appropriate.
