1 2011-06-20 Paul Eggert <eggert@cs.ucla.edu>
3 * filelock.c: Fix some buffer overrun and integer overflow issues.
4 (get_boot_time): Don't assume that gzip command string fits in 100 bytes.
5 Reformulate so as not to need the command string.
6 Invoke gzip -cd rather than gunzip, as it's more portable.
7 (lock_info_type, lock_file_1, lock_file):
8 Don't assume pid_t and time_t fit in unsigned long.
9 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10 (current_lock_owner): Prefer signed type for sizes.
11 Use memcpy, not strncpy, where memcpy is what is really wanted.
12 Don't assume (via atoi) that time_t and pid_t fit in int.
13 Check for time_t and/or pid_t out of range, e.g., via a network share.
14 Don't alloca where an auto var works fine.
16 2011-06-19 Paul Eggert <eggert@cs.ucla.edu>
18 * fileio.c: Fix some integer overflow issues.
19 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
20 Don't assume string length fits in int.
21 (directory_file_name): Don't assume string length fits in long.
22 (make_temp_name): Don't assume pid fits in int, or that its print
23 length is less than 20.
25 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
27 * coding.c (make_subsidiaries): Don't assume string length fits in int.
29 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
31 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
32 We prefer signed integers, even for size calculations.
34 * emacs.c: Don't assume string length fits in 'int'.
35 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
36 (main): Don't invoke strlen when not needed.
38 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
39 (XD_DEBUG_MESSAGE): Don't waste a byte.
41 * callproc.c (getenv_internal_1, getenv_internal)
43 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
45 * lread.c (invalid_syntax): Omit length argument.
46 All uses changed. This doesn't fix a bug, but it simplifies the
47 code away from its former Hollerith-constant appearance, and it's
48 one less 'int' to worry about when looking at integer-overflow issues.
49 (string_to_number): Simplify the 2011-04-26 change by invoking xsignal1.
51 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
52 This didn't break anything, but it didn't help either.
53 It's confusing to put a bogus integer in a place where the actual
54 value does not matter.
55 (LIST_END_P): Remove unused macro and its bogus comment.
56 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
58 2011-06-18 Paul Eggert <eggert@cs.ucla.edu>
60 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
61 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
63 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
64 We prefer signed types, and the value cannot exceed the EMACS_INT
65 range anyway (because otherwise the length would not be representable).
66 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
67 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
68 This avoids a GCC warning when WIDE_EMACS_INT.
70 * indent.c (sane_tab_width): New function.
71 (current_column, scan_for_column, Findent_to, position_indentation)
72 (compute_motion): Use it. This is just for clarity.
73 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
75 * image.c (xbm_image_p): Don't assume stated width and height fit in int.
77 * lisp.h (lint_assume): New macro.
78 * composite.c (composition_gstring_put_cache):
79 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
81 * editfns.c, insdel.c:
82 Omit unnecessary forward decls, to simplify future changes.
84 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
86 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
88 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
89 Use much-faster test for byte-length change.
90 Don't assume string byte-length fits in 'int'.
91 Check that character arg fits in 'int'.
92 (mapcar1): Declare byte as byte, for clarity.
94 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
96 * fns.c (concat): Catch string overflow earlier.
97 Do not rely on integer wraparound.
99 * dispextern.h (struct it.overlay_strings_charpos): EMACS_INT, not int.
101 2011-06-17 Paul Eggert <eggert@cs.ucla.edu>
103 * dispextern.h (struct it.selective): Now EMACS_INT, not int.
104 * xdisp.c (forward_to_next_line_start)
105 (back_to_previous_visible_line_start)
106 (reseat_at_next_visible_line_start, next_element_from_buffer):
107 Don't arbitrarily truncate the value of 'selective' to int.
109 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
111 * composite.c: Don't truncate sizes to 'int'.
112 (composition_gstring_p, composition_reseat_it)
113 (composition_adjust_point): Use EMACS_INT, not int.
114 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
115 not EMACS_UINT, for indexes.
117 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
119 * buffer.c: Include <verify.h>.
120 (struct sortvec.priority, struct sortstr.priority):
121 Now EMACS_INT, not int.
122 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
123 (struct sortstr.size, record_overlay_string)
124 (struct sortstrlist.size, struct sortlist.used):
125 Don't truncate size to int.
126 (record_overlay_string): Check for size-calculation overflow.
127 (init_buffer_once): Check at compile-time, not run-time.
129 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
131 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
132 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
133 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
135 Improve buffer-overflow checking (Bug#8873).
136 * fileio.c (Finsert_file_contents):
137 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
138 Remove the old (too-loose) buffer overflow checks.
139 They weren't needed, since make_gap checks for buffer overflow.
140 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
141 The old code merely checked for Emacs fixnum overflow, and relied
142 on undefined (wraparound) behavior. The new code avoids undefined
143 behavior, and also checks for ptrdiff_t and/or size_t overflow.
145 * editfns.c (Finsert_char): Don't dump core with very negative counts.
146 Tune. Don't use wider integers than needed. Don't use alloca.
147 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
149 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
151 * insdel.c, lisp.h (buffer_overflow): New function.
152 (insert_from_buffer_1, replace_range, replace_range_2):
153 * insdel.c (make_gap_larger):
154 * editfns.c (Finsert_char):
155 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
157 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
159 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
161 Integer overflow and signedness fixes (Bug#8873).
163 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
164 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
166 * fileio.c: Don't assume EMACS_INT fits in off_t.
167 (emacs_lseek): New static function.
168 (Finsert_file_contents, Fwrite_region): Use it.
169 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
171 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
173 * fns.c: Don't overflow int when computing a list length.
174 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
175 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
176 truncation on 64-bit hosts. Check for QUIT every
177 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
178 faster and is responsive enough.
179 (Flength): Report an error instead of overflowing an integer.
180 (Fsafe_length): Return a float if the value is not representable
181 as a fixnum. This shouldn't happen except in contrived situations.
182 (Fnthcdr, Fsort): Don't assume list length fits in int.
183 (Fcopy_sequence): Don't assume vector length fits in int.
185 * alloc.c: Check that resized vectors' lengths fit in fixnums.
186 (header_size, word_size): New constants.
187 (allocate_vectorlike): Don't check size overflow here.
188 (allocate_vector): Check it here instead, since this is the only
189 caller of allocate_vectorlike that could cause overflow.
190 Check that the new vector's length is representable as a fixnum.
192 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
193 The previous code was bogus. For example, next_almost_prime (32)
194 returned 39, which is undesirable as it is a multiple of 3; and
195 next_almost_prime (24) returned 25, which is a multiple of 5 so
196 why was the code bothering to check for multiples of 7?
198 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
200 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
202 Variadic C functions now count arguments with ptrdiff_t.
203 This partly undoes my 2011-03-30 change, which replaced int with size_t.
204 Back then I didn't know that the Emacs coding style prefers signed int.
205 Also, in the meantime I found a few more instances where arguments
206 were being counted with int, which may truncate counts on 64-bit
207 machines, or EMACS_INT, which may be unnecessarily wide.
208 * lisp.h (struct Lisp_Subr.function.aMANY)
209 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
210 Arg counts are now ptrdiff_t, not size_t.
211 All variadic functions and their callers changed accordingly.
212 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
213 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
214 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
215 * callint.c (Fcall_interactively): Check arg count for overflow,
216 to avoid potential buffer overrun. Use signed char, not 'int',
217 for 'varies' array, so that we needn't bother to check its size
218 calculation for overflow.
219 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
220 * eval.c (apply_lambda):
221 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
222 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
223 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
225 * callint.c (Fcall_interactively): Don't use index var as event count.
227 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
228 * mem-limits.h (SIZE): Remove; no longer used.
230 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
232 Remove unnecessary casts.
233 * xterm.c (x_term_init):
234 * xfns.c (x_set_border_pixel):
235 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
236 These aren't needed now that we assume ANSI C.
238 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
239 It's more likely to cause problems (due to unsigned overflow)
242 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
244 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
246 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
248 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
250 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
252 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
254 GLYPH_CODE_FACE returns EMACS_INT, not int.
255 * dispextern.h (merge_faces):
256 * xfaces.c (merge_faces):
257 * xdisp.c (get_next_display_element, next_element_from_display_vector):
258 Don't assume EMACS_INT fits in int.
260 * character.h (CHAR_VALID_P): Remove unused parameter.
261 * fontset.c, lisp.h, xdisp.c: All uses changed.
263 * editfns.c (Ftranslate_region_internal): Omit redundant test.
265 * fns.c (concat): Minor tuning based on overflow analysis.
266 This doesn't fix any bugs. Use int to hold character, instead
267 of constantly refetching from Emacs object. Use XFASTINT, not
268 XINT, for value known to be a character. Don't bother comparing
269 a single byte to 0400, as it's always less.
271 * floatfns.c (Fexpt):
272 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
274 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
277 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
279 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
280 Without this fix, on a 64-bit host (aset S 0 4294967386) would
281 incorrectly succeed when S was a string, because 4294967386 was
282 truncated before it was used.
284 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
285 Otherwise, an out-of-range integer could cause undefined behavior
288 * composite.c: Use int, not EMACS_INT, for characters.
289 (fill_gstring_body, composition_compute_stop_pos): Use int, not
290 EMACS_INT, for values that are known to be in character range.
291 This doesn't fix any bugs but is the usual style inside Emacs and
292 may generate better code on 32-bit machines.
294 Make sure a 64-bit char is never passed to ENCODE_CHAR.
295 This is for reasons similar to the recent CHAR_STRING fix.
296 * charset.c (Fencode_char): Check that character arg is actually
297 a character. Pass an int to ENCODE_CHAR.
298 * charset.h (ENCODE_CHAR): Verify that the character argument is no
299 wider than 'int', as a compile-time check to prevent future regressions
302 * character.c (char_string): Remove unnecessary casts.
304 Make sure a 64-bit char is never passed to CHAR_STRING.
305 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
306 by silently ignoring the top 32 bits, allowing some values
307 that were far too large to be valid characters.
308 * character.h: Include <verify.h>.
309 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
310 arguments are no wider than unsigned, as a compile-time check
311 to prevent future regressions in this area.
313 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
314 (Fsubst_char_in_region):
316 * xdisp.c (decode_mode_spec_coding):
317 Adjust to CHAR_STRING's new requirement.
318 * editfns.c (Finsert_char, Fsubst_char_in_region):
319 * fns.c (concat): Check that character args are actually
320 characters. Without this test, these functions did the wrong
321 thing with wildly out-of-range values on 64-bit hosts.
323 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
324 These casts should not be needed on 32-bit hosts, either.
325 * keyboard.c (read_char):
326 * lread.c (Fload): Remove casts to unsigned.
328 * lisp.h (UNSIGNED_CMP): New macro.
329 This fixes comparison bugs on 64-bit hosts.
330 (ASCII_CHAR_P): Use it.
331 * casefiddle.c (casify_object):
332 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
333 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
334 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
335 * dispextern.h (FACE_FROM_ID):
336 * keyboard.c (read_char): Use UNSIGNED_CMP.
338 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
339 not to EMACS_INT, to avoid GCC warning.
341 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
343 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
344 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
345 isn't needed on 32-bit machines.
347 * buffer.c (Fgenerate_new_buffer_name):
348 Use EMACS_INT for count, not int.
349 (advance_to_char_boundary): Return EMACS_INT, not int.
351 * data.c (Qcompiled_function): Now static.
353 * window.c (window_body_lines): Now static.
355 * image.c (gif_load): Rename local to avoid shadowing.
357 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
358 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
359 * alloc.c (make_save_value): Integer argument is now of type
361 (mark_object): Use ptrdiff_t, not int.
362 * lisp.h (pD): New macro.
363 * print.c (print_object): Use it.
365 * alloc.c: Use EMACS_INT, not int, to count objects.
366 (total_conses, total_markers, total_symbols, total_vector_size)
367 (total_free_conses, total_free_markers, total_free_symbols)
368 (total_free_floats, total_floats, total_free_intervals)
369 (total_intervals, total_strings, total_free_strings):
370 Now EMACS_INT, not int. All uses changed.
371 (Fgarbage_collect): Compute overall total using a double, so that
372 integer overflow is less likely to be a problem. Check for overflow
373 when converting back to an integer.
374 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
375 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
376 These were 'int' variables that could overflow on 64-bit hosts;
377 they were never used, so remove them instead of repairing them.
378 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
379 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
380 Previously, this ceilinged at INT_MAX, but that doesn't work on
382 (allocate_pseudovector): Don't use EMACS_INT when int would do.
384 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
385 (allocate_vectorlike): Check for ptrdiff_t overflow.
386 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
387 when a (possibly-narrower) signed value would do just as well.
388 We prefer using signed arithmetic, to avoid comparison confusion.
390 * alloc.c: Catch some string size overflows that we were missing.
391 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
392 for convenience in STRING_BYTES_MAX.
393 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
394 The definition here is exact; the one in lisp.h was approximate.
395 (allocate_string_data): Check for string overflow. This catches
396 some instances we weren't catching before. Also, it catches
397 size_t overflow on (unusual) hosts where SIZE_MAX <= min
398 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
399 and ptrdiff_t and EMACS_INT are both 64 bits.
401 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
402 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
403 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
405 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
407 * alloc.c (Fmake_string): Check for out-of-range init.
409 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
411 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
413 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
415 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
416 xg_get_default_scrollbar_width.
418 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
419 (int_gtk_range_get_value): Move to the scroll bar part of the file.
420 (style_changed_cb): Call update_theme_scrollbar_width and call
421 x_set_scroll_bar_default_width and xg_frame_set_char_size for
422 all frames (Bug#8505).
423 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
424 Call gtk_window_set_resizable if HAVE_GTK3.
425 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
426 and height if HAVE_GTK3 (Bug#8505).
427 (scroll_bar_width_for_theme): New variable.
428 (update_theme_scrollbar_width): New function.
429 (xg_get_default_scrollbar_width): Move code to
430 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
431 (xg_initialize): Call update_theme_scrollbar_width.
433 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
435 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
437 2011-06-12 Martin Rudalics <rudalics@gmx.at>
439 * frame.c (make_frame): Call other_buffer_safely instead of
442 * window.c (temp_output_buffer_show): Call display_buffer with
443 second argument Vtemp_buffer_show_specifiers and reset latter
444 immediately after the call.
445 (Vtemp_buffer_show_specifiers): New variable.
446 (auto_window_vscroll_p, next_screen_context_lines)
447 (Vscroll_preserve_screen_position): Remove leading asterisks from
450 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
452 Fix minor problems found by GCC 4.6.0 static checking.
453 * buffer.c (Qclone_number): Remove for now, as it's unused.
454 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
455 (record_buffer): Remove unused local.
456 * frame.c (other_visible_frames, frame_buffer_list): Now static.
457 (set_frame_buffer_list): Remove; unused.
458 * frame.h (other_visible_frames): Remove decl.
459 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
460 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
461 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
463 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
464 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
465 Define only if HAVE_GPM.
466 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
467 (update_hints_inhibit): Remove; never set. All uses removed.
468 * widgetprv.h (emacsFrameClassRec): Remove decl.
469 * window.c (delete_deletable_window): Now returns void, since it
470 wasn't returning anything.
471 (compare_window_configurations): Remove unused locals.

973 (bidi_level_of_next_char): Call bidi_fetch_char and
974 bidi_fetch_char_advance instead of FETCH_CHAR and
976 (bidi_init_it): Initialize new members.
977 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
979 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
980 instead of using explicit *_CHAR codes.
981 (bidi_resolve_explicit, bidi_resolve_weak):
982 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
983 bidirectional text is supported only in multibyte buffers.
984 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
985 it to initialize the frame_window_p member of struct bidi_it.
986 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
987 (bidi_resolve_explicit, bidi_resolve_weak)
988 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
989 bidi_it->nchars is non-positive.
990 (bidi_level_of_next_char): Don't try to lookup the cache for the
991 next/previous character if nothing is cached there yet, or if we
992 were just reseat()'ed to a new position.
994 * xdisp.c (set_cursor_from_row): Set start and stop points
995 according to the row's direction when priming the loop that looks
996 for the glyph on which to display cursor.
997 (single_display_spec_intangible_p): Function deleted.
998 (display_prop_intangible_p): Reimplement to call
999 handle_display_spec instead of single_display_spec_intangible_p.
1000 Accept 3 additional arguments needed by handle_display_spec.
1001 This fixes incorrect cursor motion across display property with complex
1002 values: lists, `(when COND...)' forms, etc.
1003 (single_display_spec_string_p): Support property values that are
1004 lists with the argument STRING its top-level element.
1005 (display_prop_string_p): Fix the condition for processing a
1006 property that is a list to be consistent with handle_display_spec.
1007 (handle_display_spec): New function, refactored from the
1008 last portion of handle_display_prop.
1009 (compute_display_string_pos): Accept additional argument
1010 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
1011 value of a `display' property is a "replacing spec".
1012 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
1013 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
1014 the display property, but just return a value indicating whether
1015 the display property will replace the characters it covers.
1016 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
1017 frame_window_p members of struct bidi_it.
1018 (compute_display_string_pos, compute_display_string_end):
1020 (push_it): Accept second argument POSITION, where pop_it should
1021 jump to continue iteration.
1022 (reseat_1): Initialize bidi_it.disp_pos.
1024 * keyboard.c (adjust_point_for_property): Adjust the call to
1025 display_prop_intangible_p to its new signature.
1027 * dispextern.h (struct bidi_it): New member frame_window_p.
1028 (bidi_init_it): Update prototypes.
1029 (display_prop_intangible_p): Update prototype.
1030 (compute_display_string_pos, compute_display_string_end):
1032 (struct bidi_it): New members nchars and disp_pos. ch_len is now
1035 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
1037 Malloc failure behavior now depends on size of allocation.
1038 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
1039 * lisp.h: Change signatures accordingly.
1040 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
1041 All callers changed. (Bug#8762)
1043 * gnutls.c: Use Emacs's memory allocators.
1044 Without this change, the gnutls library would invoke malloc etc.
1045 directly, which causes problems on non-SYNC_INPUT hosts, and which
1046 runs afoul of improving memory_full behavior. (Bug#8761)
1047 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1048 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1049 xfree instead of the default malloc, realloc, free.
1050 (Fgnutls_boot): No need to check for memory allocation failure,
1051 since xmalloc does that for us.
1053 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1054 * category.c (hash_get_category_set):
1055 * ccl.c (ccl_driver):

1069 * image.c (make_image, search_image_cache, lookup_image)
1070 (xpm_put_color_table_h):
1071 * lisp.h (struct Lisp_Hash_Table):
1072 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1073 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1074 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1075 * alloc.c (allocate_vectorlike):
1076 Check for overflow in vector size calculations.
1077 * ccl.c (ccl_driver):
1078 Check for overflow when converting EMACS_INT to int.
1079 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1080 need to be updated by these changes.
1081 * fns.c (make_hash_table, maybe_resize_hash_table):
1082 Check for integer overflow with large hash tables.
1083 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1084 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1085 (SXHASH_REDUCE): New macro.
1086 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1087 Use it instead of discarding useful hash info with large hash values.
1088 (sxhash_float): New function.
1089 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1090 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1091 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1092 Rewrite to use FIXNUM_BITS, as this simplifies things.
1093 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1094 Adjust signatures to match updated version of code.
1095 (consing_since_gc): Now EMACS_INT, since a single hash table can
1096 use more than INT_MAX bytes.
1098 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1100 Make it possible to build with GCC-4.6+ -O2 -flto.
1102 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1104 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1106 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1107 Call minibuffer-inactive-mode.
1109 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1111 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1112 Update dependencies.
1114 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1116 * data.c (init_data): Remove code for UTS, this system is not
1119 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1121 Don't force ./temacs to start in terminal mode.
1123 * frame.c (make_initial_frame): Initialize faces in all cases, not
1124 only when CANNOT_DUMP is defined.
1125 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1127 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1129 * dispnew.c (add_window_display_history): Use const for the string
1130 pointer. Remove declaration, not needed.
1132 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1134 Use 'inline', not 'INLINE'.
1135 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1136 * alloc.c, fontset.c (INLINE): Remove.
1137 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1138 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1139 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1140 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1141 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1143 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1145 Make it possible to run ./temacs.
1147 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1148 syms_of_callproc does the same thing. Remove test for
1149 "initialized", do it in the caller.
1150 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1152 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1154 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1155 (read_minibuf): Use get_minibuffer.
1156 (syms_of_minibuf): Use DEFSYM.
1157 (Qmetadata): New var.
1158 * data.c (Qbuffer): Don't make it static.
1159 (syms_of_data): Use DEFSYM.
1161 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1163 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1164 (CCL_CODE_MIN): New macro.
1166 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1168 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1170 * eval.c (Qdebug): Now static.
1171 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1172 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1173 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1175 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1177 * image.c: Various fixes to ImageMagick code comments.
1178 (Fimagemagick_types): Doc fix.
1180 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1182 Minor fixes prompted by GCC 4.6.0 warnings.
1184 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1186 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1187 (x_clipboard_manager_save_all): Move extern decl to ...
1188 * xterm.h: ... here, so that it can be checked for consistency.
1190 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1192 * xselect.c (x_clipboard_manager_save_frame)
1193 (x_clipboard_manager_save_all): New functions.
1194 (Fx_clipboard_manager_save): Lisp function deleted.
1196 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1197 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1199 * xterm.h: Update prototype.
1201 2011-05-28 William Xu <william.xwl@gmail.com>
1203 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1206 2011-05-28 Jim Meyering <meyering@redhat.com>
1208 Avoid a sign-extension bug in crypto_hash_function.
1209 * fns.c (to_uchar): Define.
1210 (crypto_hash_function): Use it to convert some newly-signed
1211 variables to unsigned, to avoid sign-extension bugs. For example,
1212 without this change, (md5 "truc") would evaluate to
1213 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1214 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1215 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1217 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1219 Integer overflow fixes.
1221 * dbusbind.c: Serial number integer overflow fixes.
1222 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1223 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1224 to hold a serial number that is too large for a fixnum.
1225 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1226 Check for serial numbers out of range. Decode any serial number
1227 that was so large that it became a float. (Bug#8722)
1229 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1230 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1231 Use XFASTINT rather than XUINT when numbers are nonnegative.
1232 (xd_append_arg, Fdbus_method_return_internal):
1233 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1234 arguments, check that Lisp number is nonnegative, rather than
1235 silently wrapping negative numbers around. (Bug#8722)
1236 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1239 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1241 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1243 ccl: add integer overflow checks
1244 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1245 (IN_INT_RANGE): New macros.
1246 (ccl_driver): Use them to check for integer overflow when
1247 decoding a CCL program. Many of the new checks are whether XINT (x)
1248 fits in int; it doesn't always, on 64-bit hosts. The new version
1249 doesn't catch all possible integer overflows, but it's an
1250 improvement. (Bug#8719)
1252 * alloc.c (make_event_array): Use XINT, not XUINT.
1253 There's no need for unsigned here.
1255 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1256 This follows up to the 2011-05-06 change that substituted uintptr_t
1257 for EMACS_INT. This case wasn't caught back then.
1259 Rework Fformat to avoid integer overflow issues.
1260 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1261 now (part of C89). Include <verify.h>.
1262 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1263 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1264 (Fformat): Avoid the prepass trying to compute sizes; it was only
1265 approximate and thus did not catch overflow reliably. Instead, walk
1266 through the format just once, formatting and computing sizes as we go,
1267 checking for integer overflow at every step, and allocating a larger
1268 buffer as needed. Keep track separately whether the format is
1269 multibyte. Keep only the most-recently calculated precision, rather
1270 than them all. Record whether each argument has been converted to
1271 string. Use EMACS_INT, not int, for byte and char and arg counts.
1272 Support field widths and precisions larger than INT_MAX. Avoid
1273 sprintf's undefined behavior with conversion specifications such as %#d
1274 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1275 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1276 formatting out-of-range floating point numbers with int
1279 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1281 * data.c: Avoid integer truncation in expressions involving floats.
1282 * data.c: Include <intprops.h>.
1283 (arith_driver): When there's an integer overflow in an expression
1284 involving floating point, convert the integers to floating point
1285 so that the resulting value does not suffer from catastrophic
1286 integer truncation. For example, on a 64-bit host (* 4
1287 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1288 Do not rely on undefined behavior after integer overflow.
1290 merge count_size_as_multibyte, parse_str_to_multibyte
1291 * character.c, character.h (count_size_as_multibyte):
1292 Rename from parse_str_to_multibyte; all uses changed.
1293 Check for integer overflow.
1294 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1295 since it's now a duplicate of the other. This is more of
1296 a character than a buffer op, so better that it's in character.c.
1297 * fns.c, print.c: Adjust to above changes.
1299 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1301 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1303 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1305 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1306 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1307 (x_clipboard_manager_save): Now static.
1308 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1310 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1311 (crypto_hash_function): Now static.
1312 Fix pointer signedness problems. Avoid unnecessary initializations.
1314 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1316 * termhooks.h (Vselection_alist): Make it terminal-local.
1318 * terminal.c (create_terminal): Initialize it.
1320 * xselect.c: Support for clipboard managers.
1321 (Vselection_alist): Move to termhooks.h as terminal-local var.

1326 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1327 (x_own_selection, x_get_local_selection, x_convert_selection):
1328 New arg, specifying work frame. Use terminal-local Vselection_alist.
1329 (some_frame_on_display): Delete unused function.
1330 (Fx_own_selection_internal, Fx_get_selection_internal)
1331 (Fx_disown_selection_internal, Fx_selection_owner_p)
1332 (Fx_selection_exists_p): New optional frame arg.
1333 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1334 (x_handle_selection_clear): Don't treat other terminals with the
1335 same keyboard specially. Use the terminal-local Vselection_alist.
1336 (x_clear_frame_selections): Use Frun_hook_with_args.
1338 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1340 * xterm.h: Add support for those atoms.
1342 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1344 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1345 (converted_selections, conversion_fail_tag): New global variables.
1346 (x_selection_request_lisp_error): Free the above.
1347 (x_get_local_selection): Remove unnecessary code.
1348 (x_reply_selection_request): Args changed; handle arbitrary array
1349 of converted selections stored in converted_selections.
1350 Separate the XChangeProperty and SelectionNotify steps.
1351 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1352 (x_convert_selection): New function.
1353 (x_handle_selection_event): Simplify.
1354 (x_get_foreign_selection): Don't ignore incoming requests while
1355 waiting for an answer; this will fail when we implement
1356 SAVE_TARGETS, and seems unnecessary anyway.
1357 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1358 (Vx_sent_selection_functions): Doc fix.
1360 2011-05-26 Leo Liu <sdl.web@gmail.com>
1362 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1364 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1366 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1368 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1369 for fringe update if it has periodic bitmap.
1370 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1371 and fringe_bitmap_periodic_p.
1373 * fringe.c (get_fringe_bitmap_data): New function.
1374 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1375 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1376 row. Mark glyph row for fringe update if periodicity changed.
1378 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1379 for fringe update unless it has periodic bitmap.
1381 2011-05-25 Kenichi Handa <handa@m17n.org>
1383 * xdisp.c (get_next_display_element): Set correct it->face_id for

1399 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1400 Remove macros that are defined and never used.
1401 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1403 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1405 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1406 (Fx_get_selection_internal): Minor cleanup.
1407 (Fx_own_selection_internal): Rename arguments for consistency with
1410 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1412 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.

1421 last enabled row in the desired matrix touches the bottom boundary.
1423 2011-05-21 Glenn Morris <rgm@gnu.org>
1425 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1426 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1427 and add some more files.
1429 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1431 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1432 report_file_error introduced by the change from 2011-05-07.
1434 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1436 * systime.h (Time): Define only if emacs is defined.
1437 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1438 where the include path doesn't have X11/X.h by default. See
1439 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1441 2011-05-20 Kenichi Handa <handa@m17n.org>
1443 * composite.c (find_automatic_composition): Fix previous change.
1445 2011-05-20 Glenn Morris <rgm@gnu.org>
1447 * lisp.mk: New file, split from Makefile.in.
1448 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1449 (shortlisp): Remove.
1450 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1452 2011-05-19 Glenn Morris <rgm@gnu.org>
1454 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1455 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1456 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1457 (lisp): Set the order to that of loadup.el.
1458 (shortlisp): Make it a copy of $lisp.
1459 (SOME_MACHINE_LISP): Remove.
1460 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1461 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1463 2011-05-18 Kenichi Handa <handa@m17n.org>
1465 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1466 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1467 (find_automatic_composition): Mostly rewrite for efficiency.
1469 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1471 * makefile.w32-in: Update dependencies.
1473 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1475 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1476 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1478 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1480 Fix some integer overflow issues, such as string length overflow.
1482 * insdel.c (count_size_as_multibyte): Check for string overflow.
1484 * character.c (lisp_string_width): Check for string overflow.
1485 Use EMACS_INT, not int, for string indexes and lengths; in
1486 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1487 the resulting string length overflows an EMACS_INT; instead,
1488 report a string overflow if no precision given. When checking for
1489 precision exhaustion, use a check that cannot possibly have
1490 integer overflow. (Bug#8675)
1491 * character.h (lisp_string_width): Adjust to new signature.
1493 * alloc.c (string_overflow): New function.
1494 (Fmake_string): Use it. This doesn't change behavior, but saves
1495 a few bytes and will simplify future changes.
1496 * character.c (string_escape_byte8): Likewise.
1497 * lisp.h (string_overflow): New decl.
1499 Fixups, following up to the user-interface timestamp change.
1500 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1501 for UI timestamps, instead of unsigned long.
1502 * msdos.c (mouse_get_pos): Likewise.
1503 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1504 * w32gui.h (Time): Define by including "systime.h" rather than by
1505 declaring it ourselves. (Bug#8664)
1507 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1508 * image.c (clear_image_cache): Likewise.
1510 * term.c (term_mouse_position): Don't assume time_t wraparound.
1512 Be more systematic about user-interface timestamps.
1513 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1514 and sometimes 'EMACS_UINT', to represent these timestamps.
1515 This change causes it to use 'Time' uniformly, as that's what X uses.
1516 This makes the code easier to follow, and makes it easier to catch
1517 integer overflow bugs such as Bug#8664.
1518 * frame.c (Fmouse_position, Fmouse_pixel_position):
1519 Use Time, not unsigned long, for user-interface timestamps.
1520 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1521 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1522 * keyboard.h (last_event_timestamp): Likewise.
1523 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1524 * menu.h (xmenu_show): Likewise.
1525 * term.c (term_mouse_position): Likewise.
1526 * termhooks.h (struct input_event.timestamp): Likewise.
1527 (struct terminal.mouse_position_hook): Likewise.
1528 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1529 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1530 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1531 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1533 * menu.h, termhooks.h: Include "systime.h", for Time.
1535 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1536 Don't assume that the difference between two unsigned long values
1537 can fit into an integer. At this point, we know button_down_time
1538 <= event->timestamp, so the difference must be nonnegative, so
1539 there's no need to cast the result if double-click-time is
1540 nonnegative, as it should be; check that it's nonnegative, just in
1541 case. This bug is triggered when events are more than 2**31 ms
1542 apart (about 25 days). (Bug#8664)
1544 * xselect.c (last_event_timestamp): Remove duplicate decl.
1545 (x_own_selection): Remove needless cast to unsigned long.
1547 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1548 that always fit in int. Use a sentinel instead of a counter, to
1549 avoid a temp and to allay GCC's concerns about possible int overflow.
1550 * frame.h (struct frame): Use int for menu_bar_items_used
1551 instead of EMACS_INT, since it always fits in int.
1553 * menu.c (grow_menu_items): Check for int overflow.
1555 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1557 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1558 Before, the code was not consistent. These values cannot exceed
1559 2**31 - 1 so there's no need to make them unsigned.
1560 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1561 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1562 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1564 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1566 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1567 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1568 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1569 presumably because the widths might not match.
1571 * window.c (size_window): Avoid needless test at loop start.
1573 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1575 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1577 2011-05-12 Drew Adams <drew.adams@oracle.com>
1579 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1581 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1583 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1584 `width' to `bar_area_x' and `bar_area_width', respectively.
1585 (x_scroll_run): Take account of fringe background extension.
1587 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1588 Rename local vars `left' and `width' to `bar_area_x' and
1589 `bar_area_width', respectively.
1590 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1591 background extension.
1593 2011-05-10 Jim Meyering <meyering@redhat.com>
1595 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1597 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1599 * image.c (Finit_image_library): Return t for built-in image types,
1600 like pbm and xbm. (Bug#8640)
1602 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1604 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1606 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1608 * w32console.c (Fset_screen_color): Doc fix.
1609 (Fget_screen_color): New function.
1610 (syms_of_ntterm): Defsubr it.
1612 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1613 unlink the temporary file if Fcall_process didn't create it in the
1615 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1616 child process will be redirected to a file specified with `:file'.
1617 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1618 cue to call_process_cleanup not to close that handle.
1620 2011-05-07 Ben Key <bkey76@gmail.com>
1622 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1623 one of two shell specific rules, either bootstrap-temacs-CMD or
1624 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1625 to the previous implementation of the bootstrap-temacs rule.
1626 The bootstrap-temacs-CMD rule is similar to the previous
1627 implementation of the bootstrap-temacs rule except that it
1628 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1631 These changes, along with some changes to nt/configure.bat,
1632 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1633 earlier fix to add support for --cflags and --ldflags options
1634 that include quotes so that it works whether make uses cmd or
1637 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1639 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1640 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1642 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1643 a string. Handle both cases.
1644 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1645 (Fdbus_register_method): Use Qinvalid_function.
1647 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1649 * makefile.w32-in: Update dependencies.
1650 (LISP_H): Add inttypes.h and stdin.h.
1651 (PROCESS_H): Add unistd.h.
1653 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1655 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1656 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1658 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1660 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1662 * term.c (vfatal): Remove stray call to va_end.
1663 It's not needed and the C Standard doesn't allow it here anyway.
1665 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1666 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1668 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1671 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1673 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1675 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1677 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1679 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1681 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1682 * charset.c (Fdefine_charset_internal): Don't initialize
1683 charset.code_space[15]. The value was garbage, on hosts with
1684 32-bit int (Bug#8600).
1686 * lread.c (read_integer): Be more consistent with string-to-number.
1687 Use string_to_number to do the actual conversion; this avoids
1688 rounding errors and fixes some other screwups. Without this fix,
1689 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1690 (digit_to_number): Move earlier, for benefit of read_integer.
1691 Return -1 if the digit is out of range for the base, -2 if it is
1692 not a digit in any supported base. (Bug#8602)
1694 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1696 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1697 to match comment at start of function. This also removes a
1698 GCC warning about overflow in a 32+64-bit port.
1700 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1702 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1703 Reported by Stefan Monnier in
1704 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1705 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1706 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1708 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1709 (EMACS_UINTPTR): Likewise, with uintptr_t.
1711 * lisp.h: Prefer 64-bit EMACS_INT if available.
1712 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1713 on 32-bit hosts that have 64-bit int, so that they can access
1715 However, temporarily disable this change unless the temporary
1716 symbol WIDE_EMACS_INT is defined.
1718 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1720 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1721 This removes an assumption that EMACS_INT and long are the same
1722 width as pointers. The assumption is true for Emacs porting targets
1723 now, but we want to make other targets possible.
1724 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1725 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1726 In the rest of the code, change types of integers that hold casted
1727 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1728 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1729 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1730 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1731 No need to cast type when ORing.
1732 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1733 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1734 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1735 assume EMACS_INT is the same width as char *.
1736 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1737 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1738 Remove no-longer-needed casts.
1739 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1740 (xg_tool_bar_help_callback, xg_make_tool_item):
1741 Use EMACS_INTPTR to hold an integer
1742 that will be cast to void *; this can avoid a GCC warning
1743 if EMACS_INT is not the same width as void *.
1744 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1745 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1746 (current_message_1, set_message_1):
1747 Use a local to convert to proper width without a cast.
1748 * xmenu.c (dialog_selection_callback): Likewise.
1750 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1751 Also, don't assume VALBITS / RAND_BITS is less than 5,
1752 and don't rely on undefined behavior when shifting a 1 left into
1754 * lisp.h (get_random): Change signature to match.
1756 * lread.c (hash_string): Use size_t, not int, for hash computation.
1757 Normally we prefer signed values; but hashing is special, because
1758 it's better to use unsigned division on hash table sizes so that
1759 the remainder is nonnegative. Also, size_t is the natural width
1760 for hashing into memory. The previous code used 'int', which doesn't
1761 retain enough info to hash well into very large tables.
1762 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1764 * dbusbind.c: Don't possibly lose pointer info when converting.
1765 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1766 Use XPNTR rather than XHASH, so that the high-order bits of
1767 the pointer aren't lost when converting through void *.
1769 * eval.c (Fautoload): Don't double-shift a pointer.
1771 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1773 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1775 * gnutls.c (DEF_GNUTLS_FN):
1776 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1778 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1780 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
1783 2011-05-05 Eli Zaretskii <eliz@gnu.org>
1785 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
1786 New version that can reserve upto 2GB of heap space.
1788 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
1790 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
1792 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
1794 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
1795 `gnutls_certificate_set_x509_key_file'.
1797 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
1799 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
1800 Update dependencies.
1802 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1804 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
1805 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
1806 Remove unused parameter `fildes'.
1807 * process.c (read_process_output, send_process): Don't pass it.
1809 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1811 Fix previous change: the library cache is defined in w32.c.
1812 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
1813 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
1815 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1817 Implement dynamic loading of GnuTLS on Windows.
1819 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
1820 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
1821 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1824 * gnutls.c (Qgnutls_dll): Define.
1825 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
1826 (gnutls_*): Declare function pointers.
1827 (init_gnutls_functions): New function to initialize function pointers.
1828 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
1829 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
1830 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
1831 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
1832 (emacs_gnutls_write, emacs_gnutls_read)
1833 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
1834 (Fgnutls_available_p): New function.
1835 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
1836 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
1837 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
1839 * image.c: Include w32.h.
1840 (Vimage_type_cache): Delete.
1841 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
1842 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
1843 (w32_delayed_load): Move to w32.c.
1845 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
1847 * w32.c (QCloaded_from, Vlibrary_cache): Define.
1848 (w32_delayed_load): Move from image.c. When loading a library, record
1849 its filename in the :loaded-from property of the library id.
1850 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
1851 Initialize and staticpro them.
1852 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
1854 * process.c: Include lisp.h before w32.h, not after.
1855 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
1856 instead of gnutls_record_check_pending.
1858 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.

1903 (Fcall_process_region): Ditto.
1905 2011-04-30 Eli Zaretskii <eliz@gnu.org>
1907 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
1908 rather than `XVECTOR (FOO)->size'.
1910 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
1911 inttypes.h, as a gnulib replacement is used if it not available in
1914 2011-04-21 Eli Zaretskii <eliz@gnu.org>
1916 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
1917 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
1918 of MOST_POSITIVE_FIXNUM. (Bug#8528)
1920 * coding.c (coding_alloc_by_realloc): Error out if destination
1921 will grow beyond MOST_POSITIVE_FIXNUM.
1922 (decode_coding_emacs_mule): Abort if there isn't enough place in
1923 charbuf for the composition carryover bytes. Reserve an extra
1924 space for up to 2 characters produced in a loop.
1925 (decode_coding_iso_2022): Abort if there isn't enough place in
1926 charbuf for the composition carryover bytes.
1928 2011-04-21 Eli Zaretskii <eliz@gnu.org>
1930 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
1931 aborting when %lld or %lll format is passed.
1932 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
1933 %llo or %llx format is passed. (Bug#8545)
1935 * window.c (window_scroll_line_based): Use a marker instead of
1936 simple variables to record original value of point. (Bug#7952)
1938 * doprnt.c (doprnt): Fix the case where a multibyte sequence
1939 produced by %s or %c overflows available buffer space. (Bug#8545)
1941 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
1943 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
1944 (SIZE_MAX): Move defn after all includes, as they might #define it.
1946 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1948 * w32.c (init_environment): Warn about defaulting HOME to C:\.
1950 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1952 * keyboard.c (Qdelayed_warnings_hook): Define.
1953 (command_loop_1): Run `delayed-warnings-hook'
1954 if Vdelayed_warnings_list is non-nil.
1955 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
1956 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
1958 2011-04-28 Eli Zaretskii <eliz@gnu.org>
1960 * doprnt.c (doprnt): Don't return value smaller than the buffer
1961 size if the message was truncated. (Bug#8545).
1963 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
1965 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
1966 (Fx_window_property): #if-0 the whole functions, not just the bodies.
1968 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1970 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
1972 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
1974 * makefile.w32-in: Update dependencies.
1976 2011-04-27 Eli Zaretskii <eliz@gnu.org>
1978 Improve `doprnt' and its usage. (Bug#8545)
1979 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
1980 `format_end'. Remove support for %l as a conversion specifier.
1981 Don't use xrealloc. Improve diagnostics when the %l size modifier
1982 is used. Update the commentary.
1984 * eval.c (verror): Simplify calculation of size_t.
1986 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
1989 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
1991 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
1994 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
1996 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
1997 This makes this file independent of the recent pseudovector change.
1999 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2001 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2003 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2004 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2005 Remove unused local.
2006 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2008 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2009 GCC 4.6.0 optimizes based on type-based alias analysis.
2010 For example, if b is of type struct buffer * and v of type struct
2011 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2012 != &v->size, and therefore "v->size = 1; b->size = 2; return
2013 v->size;" must therefore return 1. This assumption is incorrect
2014 for Emacs, since it type-puns struct Lisp_Vector * with many other
2015 types. To fix this problem, this patch adds a new type struct
2016 vectorlike_header that documents the constraints on layout of vectors
2017 and pseudovectors, and helps optimizing compilers not get fooled
2018 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2019 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2020 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2022 (XSETPVECTYPE): Rewrite in terms of new macro.
2023 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2024 This is a bit clearer, and further avoids the possibility of
2025 undesirable aliasing.
2026 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2027 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2028 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2029 since Lisp_Subr is a special case (no "next" field).
2030 (ASIZE): Now uses header.size rather than size.
2031 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2032 to avoid the hassle of writing XVECTOR (foo)->header.size.
2033 (struct vectorlike_header): New type.
2034 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2035 object, to help avoid aliasing.
2036 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2037 (SUBRP): Likewise, since Lisp_Subr is a special case.
2038 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2039 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2040 (struct Lisp_Hash_Table): Combine first two members into a single
2041 struct vectorlike_header member. All uses of "size" and "next" members
2042 changed to be "header.size" and "header.next".
2043 * buffer.h (struct buffer): Likewise.
2044 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2045 * frame.h (struct frame): Likewise.
2046 * process.h (struct Lisp_Process): Likewise.
2047 * termhooks.h (struct terminal): Likewise.
2048 * window.c (struct save_window_data, struct saved_window): Likewise.
2049 * window.h (struct window): Likewise.
2050 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2051 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2052 * buffer.c (init_buffer_once): Likewise.
2053 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2055 * process.c (Fformat_network_address): Use local var for size,
2058 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2060 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2061 * data.c (atof): Remove decl; no longer used or needed.
2062 (digit_to_number): Move to lread.c.
2063 (Fstring_to_number): Use new string_to_number function, to be
2064 consistent with how the Lisp reader treats infinities and NaNs.
2065 Do not assume that floating-point numbers represent EMACS_INT
2066 without losing information; this is not true on most 64-bit hosts.
2067 Avoid double-rounding errors, by insisting on integers when
2068 parsing non-base-10 numbers, as the documentation specifies.
2069 * lisp.h (string_to_number): New decl, replacing ...
2070 (isfloat_string): Remove.
2071 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2072 (read1): Do not accept +. and -. as integers; this
2073 appears to have been a coding error. Similarly, do not accept
2074 strings like +-1e0 as floating point numbers. Do not report
2075 overflow for integer overflows unless the base is not 10 which
2076 means we have no simple and reliable way to continue.
2077 Break out the floating-point parsing into a new
2078 function string_to_number, so that Fstring_to_number parses
2079 floating point numbers consistently with the Lisp reader.
2080 (digit_to_number): Move here from data.c. Make it static inline.
2081 (E_CHAR, EXP_INT): Remove, replacing with ...
2082 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2083 (string_to_number): New function, replacing isfloat_string.
2084 This function checks for valid syntax and produces the resulting
2085 Lisp float number too. Rework it so that string-to-number
2086 no longer mishandles examples like "1.0e+". Use strtoumax,
2087 so that overflow for non-base-10 numbers is reported only when
2088 there's no portable and simple way to convert to floating point.
2090 * textprop.c (set_text_properties_1): Rewrite for clarity,
2091 and to avoid GCC warning about integer overflow.
2093 * intervals.h (struct interval): Use EMACS_INT for members
2094 where EMACS_UINT might cause problems. See
2095 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2096 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2097 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2099 (offset_intervals): Tell GCC not to worry about length overflow
2100 when negating a negative length.
2102 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2103 (overrun_check_free): Likewise.
2105 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2106 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2109 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2110 (gnutls_make_error): Rename local to avoid shadowing.
2111 (gnutls_emacs_global_deinit): ifdef out; not used.
2112 (Fgnutls_boot): Use const for pointer to readonly storage.
2113 Comment out unused local. Fix pointer signedness problems.
2115 * lread.c (openp): Don't stuff size_t into an 'int'.
2116 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2117 about possible signed overflow.
2119 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2120 (GDK_KEY_g): Don't define if already defined.
2121 (xg_prepare_tooltip): Avoid pointer signedness problem.
2122 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2124 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2125 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2127 * xfns.c (Fx_window_property): Simplify a bit,
2128 to make a bit faster and to avoid GCC 4.6.0 warning.
2129 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2131 * fns.c (internal_equal): Don't assume size_t fits in int.
2133 * alloc.c (compact_small_strings): Tighten assertion a little.
2135 Replace pEd with more-general pI, and fix some printf arg casts.
2136 * lisp.h (pI): New macro, generalizing old pEd macro to other
2137 conversion specifiers. For example, use "...%"pI"d..." rather
2138 than "...%"pEd"...".
2139 (pEd): Remove. All uses replaced with similar uses of pI.
2140 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2141 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2142 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2143 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2144 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2145 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2146 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2148 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2149 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2150 * print.c (safe_debug_print, print_object): Likewise.
2151 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2153 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2154 avoiding the 0 flag, which is not portable.
2155 * process.c (Fmake_network_process): Use pI to avoid cast.
2156 * region-cache.c (pp_cache): Likewise.
2157 * xdisp.c (decode_mode_spec): Likewise.
2158 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2159 behavior on 64-bit hosts with printf arg.
2160 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2161 (x_stop_queuing_selection_requests): Likewise.
2162 (x_get_window_property): Don't truncate byte count to an 'int'
2165 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2166 here, since it parses constructs like leading '-' and spaces,
2167 which are not wanted; and it overflows with large numbers.
2168 Instead, simply match F[0-9]+, which is what is wanted anyway.
2170 * alloc.c: Remove unportable assumptions about struct layout.
2171 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2172 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2173 (allocate_vectorlike, make_pure_vector): Use the new macros,
2174 plus offsetof, to remove unportable assumptions about struct layout.
2175 These assumptions hold on all porting targets that I know of, but
2176 they are not guaranteed, they're easy to remove, and removing them
2177 makes further changes easier.
2179 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2180 This doesn't fix a bug but makes the code clearer.
2181 (string_overrun_cookie): Now const. Use initializers that
2182 don't formally overflow signed char, to avoid warnings.
2183 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2184 can cause Emacs to crash when string overrun checking is enabled.
2185 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2186 multiple of sizeof (EMACS_INT); it need not be, if
2187 alignof(EMACS_INT) < sizeof (EMACS_INT).
2188 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2190 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2192 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
2194 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

2204 * keyboard.c (debug-on-event): New variable.
2205 (handle_user_signal): Break into debugger when debug-on-event
2206 matches the current signal symbol.

2210 * alloc.c (check_sblock, check_string_bytes)
2211 (check_string_free_list): Convert to standard C.
2213 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2215 * w32.c (emacs_gnutls_push): Fix typo.
2217 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2219 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2220 "cast to pointer from integer of different size".
2222 Improve doprnt and its use in verror. (Bug#8545)
2223 * doprnt.c (doprnt): Document the set of format control sequences
2224 supported by the function. Use SAFE_ALLOCA instead of always
2227 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2228 is one byte too soon. Don't use xrealloc; instead xfree and
2231 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2233 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2236 * gnutls.c: Renamed global_initialized to
2237 gnutls_global_initialized. Added internals for the
2238 :verify-hostname-error, :verify-error, and :verify-flags
2239 parameters of `gnutls-boot' and documented those parameters in the
2240 docstring. Start callback support.
2241 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2242 unless a fatal error occured. Call gnutls_alert_send_appropriate
2243 on error. Return error code.
2244 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
2245 (emacs_gnutls_read): Likewise.
2246 (Fgnutls_boot): Return handshake error code.
2247 (emacs_gnutls_handle_error): New function.
2248 (wsaerror_to_errno): Likewise.
2250 * w32.h (emacs_gnutls_pull): Add prototype.
2251 (emacs_gnutls_push): Likewise.
2253 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
2254 (emacs_gnutls_push): Likewise.
2256 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
2258 * process.c (wait_reading_process_output): Check if GnuTLS
2259 buffered some data internally if no FDs are set for TLS
2262 * makefile.w32-in (OBJ2): Add gnutls.$(O).
2263 (LIBS): Link to USER_LIBS.
2264 ($(BLD)/gnutls.$(0)): New target.
2266 2011-04-24 Eli Zaretskii <eliz@gnu.org>
2268 * xdisp.c (handle_single_display_spec): Rename the
2269 display_replaced_before_p argument into display_replaced_p, to
2270 make it consistent with the commentary. Fix typos in the

2285 to changes in oldXMenu/XMenu.h from 2011-04-16.
2286 (struct XMenu): Declare `help_text' `const char **'.

2422 Define only if needed.
2424 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

3041 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3042 since callers should never pass a negative size.
3043 Change the signature to match that of plain 'read' and 'write'; see
3044 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3045 * lisp.h: Update prototypes of emacs_write and emacs_read.
3047 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3049 * xdisp.c (redisplay_window): Don't try to determine the character
3050 position of the scroll margin if the window start point w->startp
3051 is outside the buffer's accessible region. (Bug#8468)
3053 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3055 Fix write-region and its subroutines for buffers > 2GB.
3056 * fileio.c (a_write, e_write): Modify declaration of arguments and
3057 local variables to support buffers larger than 2GB.
3058 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3060 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3061 argument, local variables, and return value.
3063 * lisp.h: Update prototypes of emacs_write and emacs_read.
3065 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3067 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3069 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3071 Fix more problems found by GCC 4.6.0's static checks.
3073 * xdisp.c (vmessage): Use a better test for character truncation.
3075 * charset.c (load_charset_map): <, not <=, for optimization,
3076 and to avoid potential problems with integer overflow.
3077 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3078 * casetab.c (set_identity, shuffle): Likewise.
3079 * editfns.c (Fformat): Likewise.
3080 * syntax.c (skip_chars): Likewise.
3082 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3083 This also lets GCC 4.6.0 generate slightly better loop code.
3085 * callint.c (Fcall_interactively): <, not <=, for optimization.
3086 (Fcall_interactively): Count the number of arguments produced,
3087 not the number of arguments given. This is simpler and lets GCC
3088 4.6.0 generate slightly better code.
3090 * ftfont.c: Distingish more carefully between FcChar8 and char.
3091 The previous code passed unsigned char * to a functions like
3092 strlen and xstrcasecmp that expect char *, which does not
3093 conform to the C standard.
3094 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3095 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3096 char * when the C standard requires it.
3098 * keyboard.c (read_char): Remove unused var.
3100 * eval.c: Port to Windows vsnprintf (Bug#8435).
3102 (SIZE_MAX): Define if the headers do not.
3103 (verror): Do not give up if vsnprintf returns a negative count.
3104 Instead, grow the buffer. This ports to Windows vsnprintf, which
3105 does not conform to C99. Problem reported by Eli Zaretskii.
3106 Also, simplify the allocation scheme, by avoiding the need for
3107 calling realloc, and removing the ALLOCATED variable.
3109 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3111 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3112 But keep the doprint source code for now, as we might revamp it
3113 and use it again (Bug#8435).
3114 * lisp.h (doprnt): Remove.
3115 * Makefile.in (base_obj): Remove doprnt.o.
3116 * deps.mk (doprnt.o): Remove.
3118 error: Print 32- and 64-bit integers portably (Bug#8435).
3119 Without this change, on typical 64-bit hosts error ("...%d...", N)
3120 was used to print both 32- and 64-bit integers N, which relied on
3122 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3124 * lisp.h (error, verror): Mark as printf-like functions.
3125 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3126 Report overflow in size calculations when allocating printf buffer.
3127 Do not truncate output string at its first null byte.
3128 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3129 Truncate the output at a character boundary, since vsnprintf does not
3131 * charset.c (check_iso_charset_parameter): Convert internal
3132 character to string before calling 'error', since %c now has the
3134 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3135 overflow when computing char to be passed to 'error'. Do not
3136 pass Lisp_Object to 'error'; pass the integer instead.
3137 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3138 formatted with plain %d.
3140 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3142 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3144 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3146 * xterm.c (x_catch_errors): Remove duplicate declaration.
3148 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3150 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3152 2011-04-10 Jim Meyering <meyering@redhat.com>
3154 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3155 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3156 return ssize_t not "int", and use size_t as the buffer length.
3157 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3158 * gnutls.h: Update declarations.
3159 * process.c (read_process_output): Use ssize_t, to match.
3160 (send_process): Likewise.
3162 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3164 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3166 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3168 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3169 Use unsigned char, to match FcChar8 type definition.
3171 * xterm.c (handle_one_xevent):
3172 * xmenu.c (create_and_show_popup_menu):
3173 * xselect.c (x_decline_selection_request)
3174 (x_reply_selection_request): Avoid type-punned deref of X events.
3176 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3178 Fix some uses of `int' instead of EMACS_INT.
3179 * search.c (string_match_1, fast_string_match)
3180 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3181 (scan_buffer, find_next_newline_no_quit)
3182 (find_before_next_newline, search_command, Freplace_match)
3183 (Fmatch_data): Make some `int' variables be EMACS_INT.
3185 * xdisp.c (display_count_lines): 3rd argument and return value now
3186 EMACS_INT. All callers changed.
3187 (pint2hrstr): Last argument is now EMACS_INT.
3189 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)

3205 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3206 (encode_invocation_designation): Last argument P_NCHARS is now
3208 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3209 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

3229 2011-04-08 Chong Yidong <cyd@stupidchicken.com>

3234 (syms_of_keyboard): Use DEFSYM macro.
3236 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3238 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3240 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

3251 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3253 Fix more problems found by GCC 4.6.0's static checks.
3255 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3257 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3259 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

3272 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3274 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3275 This avoids several warnings with gcc -Wstrict-overflow.
3276 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3277 directly, rather than having caller test rule sign. This avoids
3278 some unnecessary tests.
3279 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3280 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3281 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3283 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3284 (xfont_open): Avoid unnecessary tests.
3286 * composite.c (composition_gstring_put_cache): Use unsigned integer.
3288 * composite.h, composite.c (composition_gstring_put_cache):
3289 Use EMACS_INT, not int, for length.
3291 * composite.h (COMPOSITION_DECODE_REFS): New macro,
3292 breaking out part of COMPOSITION_DECODE_RULE.
3293 (COMPOSITION_DECODE_RULE): Use it.
3294 * composite.c (get_composition_id): Remove unused local vars,
3295 by using the new macro.
3297 * textprop.c (set_text_properties_1): Change while to do-while,
3298 since the condition is always true at first.
3300 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3301 (interval_deletion_adjustment): Return unsigned value.
3304 * process.c (list_processes_1, create_pty, read_process_output):

3306 (create_pty): Remove unnecessary "volatile"s.
3307 (Fnetwork_interface_info): Avoid possibility of int overflow.

3313 * syntax.c (scan_words): Remove var that was set but not used.
3314 (update_syntax_table): Use unsigned instead of int.
3316 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

3323 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3325 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3326 (font_score): Avoid potential overflow in diff calculation.

3329 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3331 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3333 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3334 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3335 can always succeed if overflow has undefined behavior.
3337 * search.c (boyer_moore, wordify): Remove vars set but not used.
3338 (wordify): Omit three unnecessary tests.
3340 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3341 All callers changed. This avoids the need for an unused var.
3343 * casefiddle.c (casify_region): Remove var that is set but not used.
3345 * dired.c (file_name_completion): Remove var that is set but not used.
3347 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3349 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3350 (Finsert_file_contents): Remove unnecessary code checking fd.
3352 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3353 Check for integer overflow on size calculations.
3355 * buffer.c (Fprevious_overlay_change): Remove var that is set
3358 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3359 Remove vars that are set but not used.
3360 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3361 (timer_check_2): Mark vars as initialized.
3363 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3365 * image.c (lookup_image): Remove var that is set but not used.
3366 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3368 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3369 that are set but not used.
3371 * xfns.c (make_invisible_cursor): Don't return garbage
3372 if XCreateBitmapFromData fails (Bug#8410).
3374 * xselect.c (x_get_local_selection, x_handle_property_notify):
3375 Remove vars that are set but not used.
3377 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3378 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3380 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3381 Remove var that is set but not used.
3382 (scroll_bar_windows_size): Now size_t, not int.
3383 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3386 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3387 (map_tty_color) [!defined MSDOS]: Likewise.
3389 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3391 * coding.c: Remove vars that are set but not used.
3392 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3393 All callers changed.
3394 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3395 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3396 (decode_coding_charset): Remove vars that are set but not used.
3398 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3399 that is set but not used.
3401 * print.c (print_object): Remove var that is set but not used.
3403 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3404 The gnulib version avoids calling malloc in the usual case,
3405 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3406 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3407 * filelock.c (current_lock_owner): Likewise.
3408 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3409 * sysdep.c: Include allocator.h, careadlinkat.h.
3410 (emacs_no_realloc_allocator): New static constant.
3411 (emacs_readlink): New function.
3412 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

3415 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3417 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3418 first non-nil return value).
3420 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3422 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3423 if not defined (Bug#8403).
3425 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3427 * xdisp.c (display_count_lines): Remove parameter `start',
3428 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3429 (get_char_face_and_encoding): Remove parameter `multibyte_p',
3430 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3432 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3433 and thereabouts. All callers changed.
3434 (get_per_char_metric): Remove parameter `f', unused since
3435 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
3437 2011-04-02 Jim Meyering <meyering@redhat.com>
3439 do not dereference NULL upon failed strdup
3440 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3441 (ns_get_family): Likewise.
3443 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3445 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
3447 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3449 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3452 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3454 Add lexical binding.
3456 * window.c (Ftemp_output_buffer_show): New fun.
3457 (Fsave_window_excursion):
3458 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3460 * lread.c (lisp_file_lexically_bound_p): New function.
3461 (Fload): Bind Qlexical_binding.
3462 (readevalloop): Remove `evalfun' arg.
3463 Bind Qinternal_interpreter_environment.
3464 (Feval_buffer): Bind Qlexical_binding.
3465 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3467 (syms_of_lread): Declare `lexical-binding'.
3469 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3471 * keyboard.c (eval_dyn): New fun.
3472 (menu_item_eval_property): Use it.
3474 * image.c (parse_image_spec): Use Ffunctionp.
3476 * fns.c (concat, mapcar1): Accept byte-code-functions.
3478 * eval.c (Fsetq): Handle lexical vars.
3479 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3480 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3481 (FletX, Flet): Obey lexical binding.
3482 (Fcommandp): Handle closures.
3483 (Feval): New `lexical' arg.
3484 (eval_sub): New function extracted from Feval. Use it almost
3485 everywhere where Feval was used. Look up vars in lexical env.
3487 (Ffunctionp): Move from subr.el.
3488 (Ffuncall): Handle closures.
3489 (apply_lambda): Remove `eval_flags'.
3490 (funcall_lambda): Handle closures and new byte-code-functions.
3491 (Fspecial_variable_p): New function.
3492 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3493 but without exporting it to Lisp.
3495 * doc.c (Fdocumentation, store_function_docstring):
3496 * data.c (Finteractive_form): Handle closures.
3498 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3501 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3503 (exec_byte_code): New function extracted from Fbyte_code to handle new
3504 calling convention for byte-code-functions. Add new byte-codes.
3506 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3508 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3510 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3512 * xdisp.c (redisplay_internal): Fix prototype.
3514 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3516 * xdisp.c (SCROLL_LIMIT): New macro.
3517 (try_scrolling): Use it when setting scroll_limit.
3518 Limit scrolling to 100 screen lines.
3519 (redisplay_window): Even when falling back on "recentering",
3520 position point in the window according to scroll-conservatively,
3521 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3523 (try_scrolling): When point is above the window, allow searching
3524 as far as scroll_max, or one screenful, to compute vertical
3525 distance from PT to the scroll margin position. This prevents
3526 try_scrolling from unnecessarily failing when
3527 scroll-conservatively is set to a value slightly larger than the
3528 window height. Clean up the case of PT below the margin at bottom
3529 of window: scroll_max can no longer be INT_MAX. When aggressive
3530 scrolling is in use, don't let point enter the opposite scroll
3531 margin as result of the scroll.
3532 (syms_of_xdisp) <scroll-conservatively>: Document the
3533 threshold of 100 lines for never-recentering scrolling.
3535 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3537 * dispextern.h (move_it_by_lines):
3538 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
3539 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
3540 (message_log_check_duplicate): Remove parameters `prev_bol' and
3541 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3542 (redisplay_internal): Remove parameter `preserve_echo_area',
3543 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3545 * indent.c (Fvertical_motion):
3546 * window.c (window_scroll_pixel_based, Frecenter):
3547 Don't pass `need_y_p' to `move_it_by_lines'.
3549 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3551 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3552 steal a few bits to be more compact.
3553 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3554 Remove unneeded casts.
3556 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3558 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3560 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3561 binding" message (bug#7967).
3563 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3565 Fix more problems found by GCC 4.6.0's static checks.
3567 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3568 Remove unused local var.
3570 * editfns.c (Fmessage_box): Remove unused local var.
3572 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3573 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3574 Omit unused local vars.
3575 * window.c (shrink_windows): Omit unused local var.
3576 * menu.c (digest_single_submenu): Omit unused local var.
3577 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3578 Omit unused local var.
3580 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3581 Don't assume string length fits in int.
3582 (keyremap_step, read_key_sequence): Use size_t for sizes.
3583 (read_key_sequence): Don't check last_real_key_start redundantly.
3585 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3586 instead of alloca (Bug#8344).
3588 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3589 (Fbacktrace_frame): Don't assume nframes fits in int.
3591 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3593 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3596 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3598 * cm.c (calccost): Turn while-do into do-while, for clarity.
3600 * keyboard.c (syms_of_keyboard): Use the same style as later
3601 in this function when indexing through an array. This also
3602 works around GCC bug 48267.
3604 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3606 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3608 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3609 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3611 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3612 This avoids undefined behavior on integer overflow, and is a bit
3613 more convenient anyway since it is compared to a size_t variable.
3615 Variadic C functions now count arguments with size_t, not int.
3616 This avoids an unnecessary limitation on 64-bit machines, which
3617 caused (substring ...) to crash on large vectors (Bug#8344).
3618 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
3619 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

3626 (funcall_lambda, mark_backtrace): Likewise.
3627 * fns.c (concat): Likewise.
3628 * frame.c (x_set_frame_parameters): Likewise.
3629 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3630 0 if not found, not -1. All callers changed.
3632 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3633 (stack_copy_size): Now size_t, not int.
3634 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3636 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3638 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3639 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3640 All callers changed.
3642 * lisp.h (multibyte_char_to_unibyte):
3643 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
3644 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3645 * character.h (CHAR_TO_BYTE8):
3646 * cmds.c (internal_self_insert):
3647 * editfns.c (general_insert_function):
3648 * keymap.c (push_key_description):
3649 * search.c (Freplace_match):
3650 * xdisp.c (message_dolog, set_message_1): All callers changed.
3652 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
3654 * keyboard.c (safe_run_hook_funcall): New function.
3655 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
3656 don't set the hook to nil, but remove the offending function instead.
3657 (Qcommand_hook_internal): Remove, unused.
3658 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
3659 Vcommand_hook_internal.
3661 * eval.c (enum run_hooks_condition): Remove.
3662 (funcall_nil, funcall_not): New functions.
3663 (run_hook_with_args): Call each function through a `funcall' argument.
3664 Remove `cond' argument, now redundant.
3665 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)

3673 * print.c (strout): Remove parameter `multibyte', unused since
3674 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
3676 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
3677 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
3678 All callers changed.
3680 * w32.c (_wsa_errlist): Use braces for struct initializers.
3682 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
3683 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
3684 All callers changed.
3685 (string_buffer_position): Likewise. Also, make static (it's never
3686 used outside xdisp.c).
3687 (cursor_row_p): Remove parameter `w', unused since
3688 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

3839 * buffer.c (Fkill_all_local_variables):
3840 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3842 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3843 unconditionnaly since it does the check itself.
3845 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3847 Fix more problems found by GCC 4.5.2's static checks.
3849 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3850 the first time through the loop, since we know p0 < p1 then.
3851 This also avoids a gcc -Wstrict-overflow warning.
3853 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3854 leading to a memory leak, possible in functions like
3855 load_charset_map_from_file that can allocate an unbounded number
3856 of objects (Bug#8318).
3858 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3859 that could (at least in theory) be that large.
3861 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3862 This is less likely to overflow, and avoids undefined behavior if
3863 overflow does occur. All callers changed. Use strtoul to scan

3874 This also avoids a warning with gcc -Wstrict-overflow.
3876 * fileio.c (Fcopy_file): Report error if fchown or fchmod
3879 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
3881 * process.c (Fmake_network_process): Use socklen_t, not int,
3882 where POSIX says socklen_t is required in portable programs.
3883 This fixes a porting bug on hosts like 64-bit HP-UX, where
3884 socklen_t is wider than int (Bug#8277).
3885 (Fmake_network_process, server_accept_connection):
3886 (wait_reading_process_output, read_process_output):

3899 Make tparam.h and terminfo.c consistent.
3900 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
3901 Include tparam.h instead, since it declares them.
3902 * cm.h (PC): Remove extern decl; tparam.h now does this.
3903 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3904 * terminfo.c: Include tparam.h, to check interfaces.
3905 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3906 (tparam): Adjust signature to match interface in tparam.h;
3907 this removes some undefined behavior. Check that outstring and len
3908 are zero, which they always are with Emacs.
3909 * tparam.h (PC, BC, UP): New extern decls.
3911 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3912 (xftfont_open): Rename locals to avoid shadowing.

3932 with a FIXME (Bug#8290).
3934 character.h: Rename locals to avoid shadowing.

3937 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
3938 (BUF_DEC_POS): Be more systematic about renaming local temporaries
3941 * textprop.c (property_change_between_p): Remove; unused.

3950 * sound.c (wav_play, au_play, Fplay_sound_internal):
3951 Fix pointer signedness.
3952 (alsa_choose_format): Remove unused local var.
3953 (wav_play): Initialize a variable to 0, to prevent undefined
3954 behavior (Bug#8278).
3956 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
3958 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
3960 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
3961 clobbering (Bug#8298).
3962 * sysdep.c (sys_subshell): Likewise.
3963 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
3965 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
3966 This should get cleaned up, so that child_setup has the
3967 same signature on all platforms.
3969 * callproc.c (call_process_cleanup): Now static.
3970 (relocate_fd): Rename locals to avoid shadowing.
3972 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
3974 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
3975 not to be necessary, and produces flickering.
3977 2011-03-20 Glenn Morris <rgm@gnu.org>
3979 * config.in: Remove file.
3981 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

4026 Define only if needed.
4028 * unexelf.c (unexec): Name an expression,
4029 to avoid gcc -Wbad-function-cast warning.
4030 Use a different way to cause a compilation error if anyone uses
4031 n rather than nn, a way that does not involve shadowing.
4032 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4034 * deps.mk (unexalpha.o): Remove; unused.
4036 New file unexec.h, the (simple) interface for unexec (Bug#8267).

4134 avoids undefined behavior in theory.
4136 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4138 Use functions, not macros, for up- and down-casing (Bug#8254).
4139 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4140 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4141 to use the following functions instead of these macros.
4142 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4143 EMACS_INT, since callers assume the returned value fits in int.

4158 (WORDCHAR_P): Likewise. This one is never needed, but is used

4160 the #if 0 of that comment.
4161 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4162 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

4204 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4205 * buffer.h: ... to here, because these macros use current_buffer,

4252 * buffer.c (fix_overlays_before): Mark locals as initialized.
4253 (fix_start_end_in_overlays): Likewise. This function should be

4266 * process.c (serial_open, serial_configure): Move decls from here ...
4267 * systty.h: ... to here, so that they can be checked.

4624 (decode_coding_object, encode_coding_object, detect_coding_system):
4625 (decode_coding_emacs_mule): Mark variables that gcc
4626 -Wuninitialized does not deduce are never used uninitialized.
4627 (detect_coding_iso_2022): Initialize a local variable that might
4628 be used uninitialized. Leave a FIXME because it's not clear that
4629 this initialization is needed. (Bug#8211)
4630 (ISO_CODE_LF, ISO_CODE_CR, CODING_ISO_FLAG_EUC_TW_SHIFT):
4631 (ONE_MORE_BYTE_NO_CHECK, UTF_BOM, UTF_16_INVALID_P):

4662 Move these decls to tparam.h, and make them agree with what
4663 is actually in tparam.c. The previous trick of using incompatible
4664 decls in different modules does not conform to the C standard.
4665 All callers of tparam changed to use tparam's actual API.
4666 * tparam.c (tparam1, tparam, tgoto):
4667 Use const pointers where appropriate.

4676 * termchar.h (struct tty_display_info): Likewise.
4678 * term.c (term_mouse_position): Rename local to avoid shadowing.
4680 * alloc.c (mark_ttys): Move decl from here ...
