3 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
4 This is unlikely, but can occur if DPI is outlandish.
6 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
8 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9 * xrdb.c (magic_file_p, search_magic_path):
10 Omit last arg SUFFIX; it was always 0. All callers changed.
11 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
13 * xfont.c (xfont_match): Avoid need for strlen.
15 * xfns.c: Don't assume strlen fits in int.
16 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
18 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19 not unsigned long, as we prefer signed integers. All callers changed.
20 Detect integer overflow in repeat count.
21 (message_dolog): Don't assume print length fits in 39 bytes.
22 (display_mode_element): Don't assume strlen fits in int.
24 * termcap.c: Don't assume sizes fit in int and never overflow.
25 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
26 (gobble_line): Check for size-calculation overflow.
28 * minibuf.c (Fread_buffer):
29 * lread.c (intern, intern_c_string):
30 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
31 Don't assume string length fits in int.
33 * keyboard.c (parse_tool_bar_item):
34 * gtkutil.c (style_changed_cb): Avoid need for strlen.
36 * font.c: Don't assume string length fits in int.
37 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
38 Use ptrdiff_t, not int.
39 (font_intern_prop): Don't assume string length fits in int.
40 Don't assume integer property fits in fixnum.
41 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
43 * filelock.c: Fix some buffer overrun and integer overflow issues.
44 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
45 Reformulate so as not to need the command string.
46 Invoke gzip -cd rather than gunzip, as it's more portable.
47 (lock_info_type, lock_file_1, lock_file):
48 Don't assume pid_t and time_t fit in unsigned long.
49 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
50 (current_lock_owner): Prefer signed type for sizes.
51 Use memcpy, not strncpy, where memcpy is what is really wanted.
52 Don't assume (via atoi) that time_t and pid_t fit in int.
53 Check for time_t and/or pid_t out of range, e.g., via a network share.
54 Don't alloca where an auto var works fine.
56 * fileio.c: Fix some integer overflow issues.
57 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
58 Don't assume string length fits in int.
59 (directory_file_name): Don't assume string length fits in long.
60 (make_temp_name): Don't assume pid fits in int, or that its print
61 length is less than 20.
63 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
65 * coding.c (make_subsidiaries): Don't assume string length fits in int.
67 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
69 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
70 We prefer signed integers, even for size calculations.
72 * emacs.c: Don't assume string length fits in 'int'.
73 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
74 (main): Don't invoke strlen when not needed.
76 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
77 (XD_DEBUG_MESSAGE): Don't waste a byte.
79 * callproc.c (getenv_internal_1, getenv_internal)
81 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
83 * lread.c (invalid_syntax): Omit length argument.
84 All uses changed. This doesn't fix a bug, but it simplifies the
85 code away from its former Hollerith-constant appearance, and it's
86 one less 'int' to worry about when looking at integer-overflow issues.
87 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
89 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
90 This didn't break anything, but it didn't help either.
91 It's confusing to put a bogus integer in a place where the actual
92 value does not matter.
93 (LIST_END_P): Remove unused macro and its bogus comment.
94 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
96 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
97 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
99 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
100 We prefer signed types, and the value cannot exceed the EMACS_INT
101 range anyway (because otherwise the length would not be representable).
102 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
103 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
104 This avoids a GCC warning when WIDE_EMACS_INT.
106 * indent.c (sane_tab_width): New function.
107 (current_column, scan_for_column, Findent_to, position_indentation)
108 (compute_motion): Use it. This is just for clarity.
109 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
111 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
113 * lisp.h (lint_assume): New macro.
114 * composite.c (composition_gstring_put_cache):
115 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
117 * editfns.c, insdel.c:
118 Omit unnecessary forward decls, to simplify future changes.
120 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
122 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
124 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
125 Use much-faster test for byte-length change.
126 Don't assume string byte-length fits in 'int'.
127 Check that character arg fits in 'int'.
128 (mapcar1): Declare byte as byte, for clarity.
130 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
132 * fns.c (concat): Catch string overflow earlier.
133 Do not rely on integer wraparound.
135 * dispextern.h (struct it.overlay_strings_charpos)
136 (struct it.selective): Now EMACS_INT, not int.
137 * xdisp.c (forward_to_next_line_start)
138 (back_to_previous_visible_line_start)
139 (reseat_at_next_visible_line_start, next_element_from_buffer):
140 Don't arbitrarily truncate the value of 'selective' to int.
142 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
144 * composite.c: Don't truncate sizes to 'int'.
145 (composition_gstring_p, composition_reseat_it)
146 (composition_adjust_point): Use EMACS_INT, not int.
147 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
148 not EMACS_UINT, for indexes.
150 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
152 * buffer.c: Include <verify.h>.
153 (struct sortvec.priority, struct sortstr.priority):
154 Now EMACS_INT, not int.
155 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
156 (struct sortstr.size, record_overlay_string)
157 (struct sortstrlist.size, struct sortlist.used):
158 Don't truncate size to int.
159 (record_overlay_string): Check for size-calculation overflow.
160 (init_buffer_once): Check at compile-time, not run-time.
162 2011-06-20 Deniz Dogan <deniz@dogan.se>
164 * process.c (Fset_process_buffer): Clarify return value in
167 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
169 * dispnew.c (add_window_display_history): Use BVAR.
171 * xdisp.c (debug_method_add): Use BVAR.
172 (check_window_end, dump_glyph_matrix, dump_glyph)
173 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
175 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
178 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
179 check till after the cache is created in init_frame_faces.
181 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
183 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
185 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
187 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
188 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
189 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
191 Improve buffer-overflow checking (Bug#8873).
192 * fileio.c (Finsert_file_contents):
193 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
194 Remove the old (too-loose) buffer overflow checks.
195 They weren't needed, since make_gap checks for buffer overflow.
196 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
197 The old code merely checked for Emacs fixnum overflow, and relied
198 on undefined (wraparound) behavior. The new code avoids undefined
199 behavior, and also checks for ptrdiff_t and/or size_t overflow.
201 * editfns.c (Finsert_char): Don't dump core with very negative counts.
202 Tune. Don't use wider integers than needed. Don't use alloca.
203 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
205 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
207 * insdel.c, lisp.h (buffer_overflow): New function.
208 (insert_from_buffer_1, replace_range, replace_range_2):
209 * insdel.c (make_gap_larger):
210 * editfns.c (Finsert_char):
211 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
213 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
215 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
217 Integer overflow and signedness fixes (Bug#8873).
219 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
220 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
222 * fileio.c: Don't assume EMACS_INT fits in off_t.
223 (emacs_lseek): New static function.
224 (Finsert_file_contents, Fwrite_region): Use it.
225 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
227 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
229 * fns.c: Don't overflow int when computing a list length.
230 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
231 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
232 truncation on 64-bit hosts. Check for QUIT every
233 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
234 faster and is responsive enough.
235 (Flength): Report an error instead of overflowing an integer.
236 (Fsafe_length): Return a float if the value is not representable
237 as a fixnum. This shouldn't happen except in contrived situations.
238 (Fnthcdr, Fsort): Don't assume list length fits in int.
239 (Fcopy_sequence): Don't assume vector length fits in int.
241 * alloc.c: Check that resized vectors' lengths fit in fixnums.
242 (header_size, word_size): New constants.
243 (allocate_vectorlike): Don't check size overflow here.
244 (allocate_vector): Check it here instead, since this is the only
245 caller of allocate_vectorlike that could cause overflow.
246 Check that the new vector's length is representable as a fixnum.
248 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
249 The previous code was bogus. For example, next_almost_prime (32)
250 returned 39, which is undesirable as it is a multiple of 3; and
251 next_almost_prime (24) returned 25, which is a multiple of 5 so
252 why was the code bothering to check for multiples of 7?
254 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
256 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
258 Variadic C functions now count arguments with ptrdiff_t.
259 This partly undoes my 2011-03-30 change, which replaced int with size_t.
260 Back then I didn't know that the Emacs coding style prefers signed int.
261 Also, in the meantime I found a few more instances where arguments
262 were being counted with int, which may truncate counts on 64-bit
263 machines, or EMACS_INT, which may be unnecessarily wide.
264 * lisp.h (struct Lisp_Subr.function.aMANY)
265 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
266 Arg counts are now ptrdiff_t, not size_t.
267 All variadic functions and their callers changed accordingly.
268 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
269 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
270 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
271 * callint.c (Fcall_interactively): Check arg count for overflow,
272 to avoid potential buffer overrun. Use signed char, not 'int',
273 for 'varies' array, so that we needn't bother to check its size
274 calculation for overflow.
275 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
276 * eval.c (apply_lambda):
277 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
278 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
279 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
281 * callint.c (Fcall_interactively): Don't use index var as event count.
283 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
284 * mem-limits.h (SIZE): Remove; no longer used.
286 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
288 Remove unnecessary casts.
289 * xterm.c (x_term_init):
290 * xfns.c (x_set_border_pixel):
291 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
292 These aren't needed now that we assume ANSI C.
294 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
295 It's more likely to cause problems (due to unsigned overflow)
298 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
300 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
302 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
304 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
306 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
308 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
310 GLYPH_CODE_FACE returns EMACS_INT, not int.
311 * dispextern.h (merge_faces):
312 * xfaces.c (merge_faces):
313 * xdisp.c (get_next_display_element, next_element_from_display_vector):
314 Don't assume EMACS_INT fits in int.
316 * character.h (CHAR_VALID_P): Remove unused parameter.
317 * fontset.c, lisp.h, xdisp.c: All uses changed.
319 * editfns.c (Ftranslate_region_internal): Omit redundant test.
321 * fns.c (concat): Minor tuning based on overflow analysis.
322 This doesn't fix any bugs. Use int to hold character, instead
323 of constantly refetching from Emacs object. Use XFASTINT, not
324 XINT, for value known to be a character. Don't bother comparing
325 a single byte to 0400, as it's always less.
327 * floatfns.c (Fexpt):
328 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
330 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
333 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
335 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
336 Without this fix, on a 64-bit host (aset S 0 4294967386) would
337 incorrectly succeed when S was a string, because 4294967386 was
338 truncated before it was used.
340 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
341 Otherwise, an out-of-range integer could cause undefined behavior
344 * composite.c: Use int, not EMACS_INT, for characters.
345 (fill_gstring_body, composition_compute_stop_pos): Use int, not
346 EMACS_INT, for values that are known to be in character range.
347 This doesn't fix any bugs but is the usual style inside Emacs and
348 may generate better code on 32-bit machines.
350 Make sure a 64-bit char is never passed to ENCODE_CHAR.
351 This is for reasons similar to the recent CHAR_STRING fix.
352 * charset.c (Fencode_char): Check that character arg is actually
353 a character. Pass an int to ENCODE_CHAR.
354 * charset.h (ENCODE_CHAR): Verify that the character argument is no
355 wider than 'int', as a compile-time check to prevent future regressions
358 * character.c (char_string): Remove unnecessary casts.
360 Make sure a 64-bit char is never passed to CHAR_STRING.
361 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
362 by silently ignoring the top 32 bits, allowing some values
363 that were far too large to be valid characters.
364 * character.h: Include <verify.h>.
365 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
366 arguments are no wider than unsigned, as a compile-time check
367 to prevent future regressions in this area.
369 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
370 (Fsubst_char_in_region):
372 * xdisp.c (decode_mode_spec_coding):
373 Adjust to CHAR_STRING's new requirement.
374 * editfns.c (Finsert_char, Fsubst_char_in_region):
375 * fns.c (concat): Check that character args are actually
376 characters. Without this test, these functions did the wrong
377 thing with wildly out-of-range values on 64-bit hosts.
379 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
380 These casts should not be needed on 32-bit hosts, either.
381 * keyboard.c (read_char):
382 * lread.c (Fload): Remove casts to unsigned.
384 * lisp.h (UNSIGNED_CMP): New macro.
385 This fixes comparison bugs on 64-bit hosts.
386 (ASCII_CHAR_P): Use it.
387 * casefiddle.c (casify_object):
388 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
389 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
390 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
391 * dispextern.h (FACE_FROM_ID):
392 * keyboard.c (read_char): Use UNSIGNED_CMP.
394 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
395 not to EMACS_INT, to avoid GCC warning.
397 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
399 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
400 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
401 isn't needed on 32-bit machines.
403 * buffer.c (Fgenerate_new_buffer_name):
404 Use EMACS_INT for count, not int.
405 (advance_to_char_boundary): Return EMACS_INT, not int.
407 * data.c (Qcompiled_function): Now static.
409 * window.c (window_body_lines): Now static.
411 * image.c (gif_load): Rename local to avoid shadowing.
413 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
414 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
415 * alloc.c (make_save_value): Integer argument is now of type
417 (mark_object): Use ptrdiff_t, not int.
418 * lisp.h (pD): New macro.
419 * print.c (print_object): Use it.
421 * alloc.c: Use EMACS_INT, not int, to count objects.
422 (total_conses, total_markers, total_symbols, total_vector_size)
423 (total_free_conses, total_free_markers, total_free_symbols)
424 (total_free_floats, total_floats, total_free_intervals)
425 (total_intervals, total_strings, total_free_strings):
426 Now EMACS_INT, not int. All uses changed.
427 (Fgarbage_collect): Compute overall total using a double, so that
428 integer overflow is less likely to be a problem. Check for overflow
429 when converting back to an integer.
430 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
431 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
432 These were 'int' variables that could overflow on 64-bit hosts;
433 they were never used, so remove them instead of repairing them.
434 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
435 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
436 Previously, this ceilinged at INT_MAX, but that doesn't work on
438 (allocate_pseudovector): Don't use EMACS_INT when int would do.
440 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
441 (allocate_vectorlike): Check for ptrdiff_t overflow.
442 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
443 when a (possibly-narrower) signed value would do just as well.
444 We prefer using signed arithmetic, to avoid comparison confusion.
446 * alloc.c: Catch some string size overflows that we were missing.
447 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
448 for convenience in STRING_BYTES_MAX.
449 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
450 The definition here is exact; the one in lisp.h was approximate.
451 (allocate_string_data): Check for string overflow. This catches
452 some instances we weren't catching before. Also, it catches
453 size_t overflow on (unusual) hosts where SIZE_MAX <= min
454 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
455 and ptrdiff_t and EMACS_INT are both 64 bits.
457 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
458 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
459 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
461 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
463 * alloc.c (Fmake_string): Check for out-of-range init.
465 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
467 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
469 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
471 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
472 xg_get_default_scrollbar_width.
474 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
475 (int_gtk_range_get_value): Move to the scroll bar part of the file.
476 (style_changed_cb): Call update_theme_scrollbar_width and call
477 x_set_scroll_bar_default_width and xg_frame_set_char_size for
478 all frames (Bug#8505).
479 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).

983 * gtkutil.h: Declare xg_get_default_scrollbar_width.
985 * xfns.c (x_set_scroll_bar_default_width): If USE_GTK, get
986 min width by calling x_set_scroll_bar_default_width (Bug#8505).
988 2011-06-05 Juanma Barranquero <lekktu@gmail.com>
990 * xdisp.c (single_display_spec_intangible_p): Remove declaration.
992 2011-06-04 Chong Yidong <cyd@stupidchicken.com>

996 (x_clipboard_manager_error_1, x_clipboard_manager_error_2):
998 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
999 Obey Vx_select_enable_clipboard_manager. Catch errors in
1000 x_clipboard_manager_save (Bug#8779).
1001 (Vx_select_enable_clipboard_manager): New variable.
1002 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
1004 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
1006 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
1008 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1010 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
1011 in the current matrix if keep_current_p is non-zero.
1013 2011-06-04 Eli Zaretskii <eliz@gnu.org>
1015 * bidi.c (bidi_level_of_next_char): Fix last change.
1017 2011-06-03 Eli Zaretskii <eliz@gnu.org>
1019 Support bidi reordering of text covered by display properties.
1021 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
1022 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
1023 (bidi_cache_search, bidi_cache_iterator_state)
1024 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
1025 (bidi_level_of_next_char, bidi_move_to_visually_next):
1026 Support character positions inside a run of characters covered by a
1028 (bidi_paragraph_init, bidi_resolve_explicit_1)
1029 (bidi_level_of_next_char): Call bidi_fetch_char and
1030 bidi_fetch_char_advance instead of FETCH_CHAR and
1032 (bidi_init_it): Initialize new members.
1033 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
1035 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
1036 instead of using explicit *_CHAR codes.
1037 (bidi_resolve_explicit, bidi_resolve_weak):
1038 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
1039 bidirectional text is supported only in multibyte buffers.
1040 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
1041 it to initialize the frame_window_p member of struct bidi_it.
1042 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
1043 (bidi_resolve_explicit, bidi_resolve_weak)
1044 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
1045 bidi_it->nchars is non-positive.
1046 (bidi_level_of_next_char): Don't try to lookup the cache for the
1047 next/previous character if nothing is cached there yet, or if we
1048 were just reseat()'ed to a new position.
1050 * xdisp.c (set_cursor_from_row): Set start and stop points
1051 according to the row's direction when priming the loop that looks
1052 for the glyph on which to display cursor.
1053 (single_display_spec_intangible_p): Function deleted.
1054 (display_prop_intangible_p): Reimplement to call
1055 handle_display_spec instead of single_display_spec_intangible_p.
1056 Accept 3 additional arguments needed by handle_display_spec.
1057 This fixes incorrect cursor motion across display property with complex
1058 values: lists, `(when COND...)' forms, etc.
1059 (single_display_spec_string_p): Support property values that are
1060 lists with the argument STRING its top-level element.
1061 (display_prop_string_p): Fix the condition for processing a
1062 property that is a list to be consistent with handle_display_spec.
1063 (handle_display_spec): New function, refactored from the
1064 last portion of handle_display_prop.
1065 (compute_display_string_pos): Accept additional argument
1066 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
1067 value of a `display' property is a "replacing spec".
1068 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
1069 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
1070 the display property, but just return a value indicating whether
1071 the display property will replace the characters it covers.
1072 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
1073 frame_window_p members of struct bidi_it.
1074 (compute_display_string_pos, compute_display_string_end):
1076 (push_it): Accept second argument POSITION, where pop_it should
1077 jump to continue iteration.
1078 (reseat_1): Initialize bidi_it.disp_pos.
1080 * keyboard.c (adjust_point_for_property): Adjust the call to
1081 display_prop_intangible_p to its new signature.
1083 * dispextern.h (struct bidi_it): New member frame_window_p.
1084 (bidi_init_it): Update prototypes.
1085 (display_prop_intangible_p): Update prototype.
1086 (compute_display_string_pos, compute_display_string_end):
1088 (struct bidi_it): New members nchars and disp_pos. ch_len is now
1091 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
1093 Malloc failure behavior now depends on size of allocation.
1094 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
1095 * lisp.h: Change signatures accordingly.
1096 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
1097 All callers changed. (Bug#8762)
1099 * gnutls.c: Use Emacs's memory allocators.
1100 Without this change, the gnutls library would invoke malloc etc.
1101 directly, which causes problems on non-SYNC_INPUT hosts, and which
1102 runs afoul of improving memory_full behavior. (Bug#8761)
1103 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1104 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1105 xfree instead of the default malloc, realloc, free.
1106 (Fgnutls_boot): No need to check for memory allocation failure,
1107 since xmalloc does that for us.
1109 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
1110 * category.c (hash_get_category_set):
1111 * ccl.c (ccl_driver):
1112 * charset.c (Fdefine_charset_internal):

1122 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
1123 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
1124 (Fsxhash, Fgethash, Fputhash, Fmaphash):
1125 * image.c (make_image, search_image_cache, lookup_image)
1126 (xpm_put_color_table_h):
1127 * lisp.h (struct Lisp_Hash_Table):
1128 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
1129 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
1130 for hashes and hash indexes, instead of 'unsigned' and 'int'.
1131 * alloc.c (allocate_vectorlike):
1132 Check for overflow in vector size calculations.
1133 * ccl.c (ccl_driver):
1134 Check for overflow when converting EMACS_INT to int.
1135 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1136 need to be updated by these changes.
1137 * fns.c (make_hash_table, maybe_resize_hash_table):
1138 Check for integer overflow with large hash tables.
1139 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1140 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1141 (SXHASH_REDUCE): New macro.
1142 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1143 Use it instead of discarding useful hash info with large hash values.
1144 (sxhash_float): New function.
1145 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1146 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1147 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1148 Rewrite to use FIXNUM_BITS, as this simplifies things.
1149 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1150 Adjust signatures to match updated version of code.
1151 (consing_since_gc): Now EMACS_INT, since a single hash table can
1152 use more than INT_MAX bytes.
1154 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1156 Make it possible to build with GCC-4.6+ -O2 -flto.
1158 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1160 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1162 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1163 Call minibuffer-inactive-mode.
1165 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1167 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1168 Update dependencies.
1170 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1172 * data.c (init_data): Remove code for UTS, this system is not
1175 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1177 Don't force ./temacs to start in terminal mode.
1179 * frame.c (make_initial_frame): Initialize faces in all cases, not
1180 only when CANNOT_DUMP is defined.
1181 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1183 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1185 * dispnew.c (add_window_display_history): Use const for the string
1186 pointer. Remove declaration, not needed.
1188 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1190 Use 'inline', not 'INLINE'.
1191 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1192 * alloc.c, fontset.c (INLINE): Remove.
1193 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1194 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1195 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1196 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1197 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1199 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1201 Make it possible to run ./temacs.
1203 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1204 syms_of_callproc does the same thing. Remove test for
1205 "initialized", do it in the caller.
1206 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1208 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1210 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1211 (read_minibuf): Use get_minibuffer.
1212 (syms_of_minibuf): Use DEFSYM.
1213 (Qmetadata): New var.
1214 * data.c (Qbuffer): Don't make it static.
1215 (syms_of_data): Use DEFSYM.
1217 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1219 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1220 (CCL_CODE_MIN): New macro.
1222 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1224 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1226 * eval.c (Qdebug): Now static.
1227 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1228 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1229 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1231 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1233 * image.c: Various fixes to ImageMagick code comments.
1234 (Fimagemagick_types): Doc fix.
1236 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1238 Minor fixes prompted by GCC 4.6.0 warnings.
1240 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1242 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1243 (x_clipboard_manager_save_all): Move extern decl to ...
1244 * xterm.h: ... here, so that it can be checked for consistency.
1246 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1248 * xselect.c (x_clipboard_manager_save_frame)
1249 (x_clipboard_manager_save_all): New functions.
1250 (Fx_clipboard_manager_save): Lisp function deleted.
1252 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1253 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1255 * xterm.h: Update prototype.
1257 2011-05-28 William Xu <william.xwl@gmail.com>
1259 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1262 2011-05-28 Jim Meyering <meyering@redhat.com>
1264 Avoid a sign-extension bug in crypto_hash_function.
1265 * fns.c (to_uchar): Define.
1266 (crypto_hash_function): Use it to convert some newly-signed
1267 variables to unsigned, to avoid sign-extension bugs. For example,
1268 without this change, (md5 "truc") would evaluate to
1269 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1270 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1271 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1273 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1275 Integer overflow fixes.
1277 * dbusbind.c: Serial number integer overflow fixes.
1278 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1279 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1280 to hold a serial number that is too large for a fixnum.
1281 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1282 Check for serial numbers out of range. Decode any serial number
1283 that was so large that it became a float. (Bug#8722)
1285 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1286 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1287 Use XFASTINT rather than XUINT when numbers are nonnegative.
1288 (xd_append_arg, Fdbus_method_return_internal):
1289 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1290 arguments, check that Lisp number is nonnegative, rather than
1291 silently wrapping negative numbers around. (Bug#8722)
1292 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1295 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1297 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1299 ccl: add integer overflow checks
1300 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1301 (IN_INT_RANGE): New macros.
1302 (ccl_driver): Use them to check for integer overflow when
1303 decoding a CCL program. Many of the new checks are whether XINT (x)
1304 fits in int; it doesn't always, on 64-bit hosts. The new version
1305 doesn't catch all possible integer overflows, but it's an
1306 improvement. (Bug#8719)
1308 * alloc.c (make_event_array): Use XINT, not XUINT.
1309 There's no need for unsigned here.
1311 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1312 This follows up to the 2011-05-06 change that substituted uintptr_t
1313 for EMACS_INT. This case wasn't caught back then.
1315 Rework Fformat to avoid integer overflow issues.
1316 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1317 now (part of C89). Include <verify.h>.
1318 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1319 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1320 (Fformat): Avoid the prepass trying to compute sizes; it was only
1321 approximate and thus did not catch overflow reliably. Instead, walk
1322 through the format just once, formatting and computing sizes as we go,
1323 checking for integer overflow at every step, and allocating a larger
1324 buffer as needed. Keep track separately whether the format is
1325 multibyte. Keep only the most-recently calculated precision, rather
1326 than them all. Record whether each argument has been converted to
1327 string. Use EMACS_INT, not int, for byte and char and arg counts.
1328 Support field widths and precisions larger than INT_MAX. Avoid
1329 sprintf's undefined behavior with conversion specifications such as %#d
1330 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1331 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1332 formatting out-of-range floating point numbers with int
1335 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1337 * data.c: Avoid integer truncation in expressions involving floats.
1338 * data.c: Include <intprops.h>.
1339 (arith_driver): When there's an integer overflow in an expression
1340 involving floating point, convert the integers to floating point
1341 so that the resulting value does not suffer from catastrophic
1342 integer truncation. For example, on a 64-bit host (* 4
1343 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1344 Do not rely on undefined behavior after integer overflow.
1346 merge count_size_as_multibyte, parse_str_to_multibyte
1347 * character.c, character.h (count_size_as_multibyte):
1348 Rename from parse_str_to_multibyte; all uses changed.
1349 Check for integer overflow.
1350 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1351 since it's now a duplicate of the other. This is more of
1352 a character than a buffer op, so better that it's in character.c.
1353 * fns.c, print.c: Adjust to above changes.
1355 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1357 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1359 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1361 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1362 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1363 (x_clipboard_manager_save): Now static.
1364 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1366 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1367 (crypto_hash_function): Now static.
1368 Fix pointer signedness problems. Avoid unnecessary initializations.
1370 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1372 * termhooks.h (Vselection_alist): Make it terminal-local.
1374 * terminal.c (create_terminal): Initialize it.
1376 * xselect.c: Support for clipboard managers.
1377 (Vselection_alist): Move to termhooks.h as terminal-local var.
1378 (LOCAL_SELECTION): New macro.
1379 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1380 (symbol_to_x_atom): Remove gratuitous arg.
1381 (x_handle_selection_request, lisp_data_to_selection_data)
1382 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1383 (x_own_selection, x_get_local_selection, x_convert_selection):
1384 New arg, specifying work frame. Use terminal-local Vselection_alist.
1385 (some_frame_on_display): Delete unused function.
1386 (Fx_own_selection_internal, Fx_get_selection_internal)
1387 (Fx_disown_selection_internal, Fx_selection_owner_p)
1388 (Fx_selection_exists_p): New optional frame arg.
1389 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1390 (x_handle_selection_clear): Don't treat other terminals with the
1391 same keyboard specially. Use the terminal-local Vselection_alist.
1392 (x_clear_frame_selections): Use Frun_hook_with_args.
1394 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1396 * xterm.h: Add support for those atoms.
1398 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1400 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1401 (converted_selections, conversion_fail_tag): New global variables.
1402 (x_selection_request_lisp_error): Free the above.
1403 (x_get_local_selection): Remove unnecessary code.
1404 (x_reply_selection_request): Args changed; handle arbitrary array
1405 of converted selections stored in converted_selections.
1406 Separate the XChangeProperty and SelectionNotify steps.
1407 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1408 (x_convert_selection): New function.
1409 (x_handle_selection_event): Simplify.
1410 (x_get_foreign_selection): Don't ignore incoming requests while
1411 waiting for an answer; this will fail when we implement
1412 SAVE_TARGETS, and seems unnecessary anyway.
1413 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1414 (Vx_sent_selection_functions): Doc fix.
1416 2011-05-26 Leo Liu <sdl.web@gmail.com>
1418 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1420 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1422 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1424 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1425 for fringe update if it has periodic bitmap.
1426 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1427 and fringe_bitmap_periodic_p.
1429 * fringe.c (get_fringe_bitmap_data): New function.
1430 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1431 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1432 row. Mark glyph row for fringe update if periodicity changed.
1434 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1435 for fringe update unless it has periodic bitmap.
1437 2011-05-25 Kenichi Handa <handa@m17n.org>
1439 * xdisp.c (get_next_display_element): Set correct it->face_id for
1440 a static composition.
1442 2011-05-24 Leo Liu <sdl.web@gmail.com>
1445 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1447 * fns.c (crypto_hash_function, Fsha1): New function.
1448 (Fmd5): Use crypto_hash_function.
1449 (syms_of_fns): Add Ssha1.
1451 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1453 * gnutls.c: Remove unused macros.
1454 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1455 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1456 Remove macros that are defined and never used.
1457 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1459 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1461 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1462 (Fx_get_selection_internal): Minor cleanup.
1463 (Fx_own_selection_internal): Rename arguments for consistency with
1466 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1468 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1470 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1472 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1474 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1476 * dispnew.c (scrolling_window): Don't exclude the case that the
1477 last enabled row in the desired matrix touches the bottom boundary.
1479 2011-05-21 Glenn Morris <rgm@gnu.org>
1481 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1482 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1483 and add some more files.
1485 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1487 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1488 report_file_error introduced by the change from 2011-05-07.
1490 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1492 * systime.h (Time): Define only if emacs is defined.
1493 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1494 where the include path doesn't have X11/X.h by default. See
1495 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1497 2011-05-20 Kenichi Handa <handa@m17n.org>
1499 * composite.c (find_automatic_composition): Fix previous change.
1501 2011-05-20 Glenn Morris <rgm@gnu.org>
1503 * lisp.mk: New file, split from Makefile.in.
1504 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1505 (shortlisp): Remove.
1506 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1508 2011-05-19 Glenn Morris <rgm@gnu.org>
1510 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1511 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1512 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1513 (lisp): Set the order to that of loadup.el.
1514 (shortlisp): Make it a copy of $lisp.
1515 (SOME_MACHINE_LISP): Remove.
1516 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1517 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1519 2011-05-18 Kenichi Handa <handa@m17n.org>
1521 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1522 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1523 (find_automatic_composition): Mostly rewrite for efficiency.
1525 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1527 * makefile.w32-in: Update dependencies.
1529 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1531 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1532 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1534 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1536 Fix some integer overflow issues, such as string length overflow.
1538 * insdel.c (count_size_as_multibyte): Check for string overflow.
1540 * character.c (lisp_string_width): Check for string overflow.
1541 Use EMACS_INT, not int, for string indexes and lengths; in
1542 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1543 the resulting string length overflows an EMACS_INT; instead,
1544 report a string overflow if no precision given. When checking for
1545 precision exhaustion, use a check that cannot possibly have
1546 integer overflow. (Bug#8675)
1547 * character.h (lisp_string_width): Adjust to new signature.
1549 * alloc.c (string_overflow): New function.
1550 (Fmake_string): Use it. This doesn't change behavior, but saves
1551 a few bytes and will simplify future changes.
1552 * character.c (string_escape_byte8): Likewise.
1553 * lisp.h (string_overflow): New decl.
1555 Fixups, following up to the user-interface timestamp change.
1556 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1557 for UI timestamps, instead of unsigned long.
1558 * msdos.c (mouse_get_pos): Likewise.
1559 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1560 * w32gui.h (Time): Define by including "systime.h" rather than by
1561 declaring it ourselves. (Bug#8664)
1563 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1564 * image.c (clear_image_cache): Likewise.
1566 * term.c (term_mouse_position): Don't assume time_t wraparound.
1568 Be more systematic about user-interface timestamps.
1569 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1570 and sometimes 'EMACS_UINT', to represent these timestamps.
1571 This change causes it to use 'Time' uniformly, as that's what X uses.
1572 This makes the code easier to follow, and makes it easier to catch
1573 integer overflow bugs such as Bug#8664.
1574 * frame.c (Fmouse_position, Fmouse_pixel_position):
1575 Use Time, not unsigned long, for user-interface timestamps.
1576 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1577 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1578 * keyboard.h (last_event_timestamp): Likewise.
1579 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1580 * menu.h (xmenu_show): Likewise.
1581 * term.c (term_mouse_position): Likewise.
1582 * termhooks.h (struct input_event.timestamp): Likewise.
1583 (struct terminal.mouse_position_hook): Likewise.
1584 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1585 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1586 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1587 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1589 * menu.h, termhooks.h: Include "systime.h", for Time.
1591 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1592 Don't assume that the difference between two unsigned long values
1593 can fit into an integer. At this point, we know button_down_time
1594 <= event->timestamp, so the difference must be nonnegative, so
1595 there's no need to cast the result if double-click-time is
1596 nonnegative, as it should be; check that it's nonnegative, just in
1597 case. This bug is triggered when events are more than 2**31 ms
1598 apart (about 25 days). (Bug#8664)
1600 * xselect.c (last_event_timestamp): Remove duplicate decl.
1601 (x_own_selection): Remove needless cast to unsigned long.
1603 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1604 that always fit in int. Use a sentinel instead of a counter, to
1605 avoid a temp and to allay GCC's concerns about possible int overflow.
1606 * frame.h (struct frame): Use int for menu_bar_items_used
1607 instead of EMACS_INT, since it always fits in int.
1609 * menu.c (grow_menu_items): Check for int overflow.
1611 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1613 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1614 Before, the code was not consistent. These values cannot exceed
1615 2**31 - 1 so there's no need to make them unsigned.
1616 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1617 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1618 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1620 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1622 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1623 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1624 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1625 presumably because the widths might not match.
1627 * window.c (size_window): Avoid needless test at loop start.
1629 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1631 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1633 2011-05-12 Drew Adams <drew.adams@oracle.com>
1635 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1637 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1639 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1640 `width' to `bar_area_x' and `bar_area_width', respectively.
1641 (x_scroll_run): Take account of fringe background extension.
1643 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1644 Rename local vars `left' and `width' to `bar_area_x' and
1645 `bar_area_width', respectively.
1646 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1647 background extension.
1649 2011-05-10 Jim Meyering <meyering@redhat.com>
1651 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1653 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1655 * image.c (Finit_image_library): Return t for built-in image types,
1656 like pbm and xbm. (Bug#8640)
1658 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1660 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1662 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1664 * w32console.c (Fset_screen_color): Doc fix.
1665 (Fget_screen_color): New function.
1666 (syms_of_ntterm): Defsubr it.
1668 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1669 unlink the temporary file if Fcall_process didn't create it in the
1671 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1672 child process will be redirected to a file specified with `:file'.
1673 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1674 cue to call_process_cleanup not to close that handle.
1676 2011-05-07 Ben Key <bkey76@gmail.com>
1678 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1679 one of two shell specific rules, either bootstrap-temacs-CMD or
1680 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1681 to the previous implementation of the bootstrap-temacs rule.
1682 The bootstrap-temacs-CMD rule is similar to the previous
1683 implementation of the bootstrap-temacs rule except that it
1684 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1687 These changes, along with some changes to nt/configure.bat,
1688 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1689 earlier fix to add support for --cflags and --ldflags options
1690 that include quotes so that it works whether make uses cmd or
1693 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1695 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1696 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1698 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1699 a string. Handle both cases.
1700 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1701 (Fdbus_register_method): Use Qinvalid_function.
1703 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1705 * makefile.w32-in: Update dependencies.
1706 (LISP_H): Add inttypes.h and stdin.h.
1707 (PROCESS_H): Add unistd.h.
1709 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1711 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1712 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1714 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1716 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1718 * term.c (vfatal): Remove stray call to va_end.
1719 It's not needed and the C Standard doesn't allow it here anyway.
1721 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1722 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1724 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1727 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1729 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1731 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1733 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1735 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1737 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1738 * charset.c (Fdefine_charset_internal): Don't initialize
1739 charset.code_space[15]. The value was garbage, on hosts with
1740 32-bit int (Bug#8600).
1742 * lread.c (read_integer): Be more consistent with string-to-number.
1743 Use string_to_number to do the actual conversion; this avoids
1744 rounding errors and fixes some other screwups. Without this fix,
1745 for example, #x1fffffffffffffff was misread as -2305843009213693952.
1746 (digit_to_number): Move earlier, for benefit of read_integer.
1747 Return -1 if the digit is out of range for the base, -2 if it is
1748 not a digit in any supported base. (Bug#8602)
1750 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
1752 * dispnew.c (scrolling_window): Return 1 if we scrolled,
1753 to match comment at start of function. This also removes a
1754 GCC warning about overflow in a 32+64-bit port.
1756 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
1758 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
1759 Reported by Stefan Monnier in
1760 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
1761 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1762 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1764 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
1765 (EMACS_UINTPTR): Likewise, with uintptr_t.
1767 * lisp.h: Prefer 64-bit EMACS_INT if available.
1768 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
1769 on 32-bit hosts that have 64-bit int, so that they can access
1771 However, temporarily disable this change unless the temporary
1772 symbol WIDE_EMACS_INT is defined.
1774 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
1776 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
1777 This removes an assumption that EMACS_INT and long are the same
1778 width as pointers. The assumption is true for Emacs porting targets
1779 now, but we want to make other targets possible.
1780 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
1781 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
1782 In the rest of the code, change types of integers that hold casted
1783 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
1784 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
1785 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
1786 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
1787 No need to cast type when ORing.
1788 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
1789 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
1790 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
1791 assume EMACS_INT is the same width as char *.
1792 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
1793 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
1794 Remove no-longer-needed casts.
1795 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
1796 (xg_tool_bar_help_callback, xg_make_tool_item):
1797 Use EMACS_INTPTR to hold an integer
1798 that will be cast to void *; this can avoid a GCC warning
1799 if EMACS_INT is not the same width as void *.
1800 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
1801 * xdisp.c (display_echo_area_1, resize_mini_window_1):
1802 (current_message_1, set_message_1):
1803 Use a local to convert to proper width without a cast.
1804 * xmenu.c (dialog_selection_callback): Likewise.
1806 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
1807 Also, don't assume VALBITS / RAND_BITS is less than 5,
1808 and don't rely on undefined behavior when shifting a 1 left into
1810 * lisp.h (get_random): Change signature to match.
1812 * lread.c (hash_string): Use size_t, not int, for hash computation.
1813 Normally we prefer signed values; but hashing is special, because
1814 it's better to use unsigned division on hash table sizes so that
1815 the remainder is nonnegative. Also, size_t is the natural width
1816 for hashing into memory. The previous code used 'int', which doesn't
1817 retain enough info to hash well into very large tables.
1818 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
1820 * dbusbind.c: Don't possibly lose pointer info when converting.
1821 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
1822 Use XPNTR rather than XHASH, so that the high-order bits of
1823 the pointer aren't lost when converting through void *.
1825 * eval.c (Fautoload): Don't double-shift a pointer.
1827 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
1829 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1831 * gnutls.c (DEF_GNUTLS_FN):
1832 * image.c (DEF_IMGLIB_FN): Make function pointers static.
1834 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
1836 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
1839 2011-05-05 Eli Zaretskii <eliz@gnu.org>
1841 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
1842 New version that can reserve upto 2GB of heap space.
1844 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
1846 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
1848 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
1850 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
1851 `gnutls_certificate_set_x509_key_file'.
1853 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
1855 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
1856 Update dependencies.
1858 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1860 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
1861 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
1862 Remove unused parameter `fildes'.
1863 * process.c (read_process_output, send_process): Don't pass it.
1865 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
1867 Fix previous change: the library cache is defined in w32.c.
1868 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
1869 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".

1959 (Fcall_process_region): Ditto.
1961 2011-04-30 Eli Zaretskii <eliz@gnu.org>
1963 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
1964 rather than `XVECTOR (FOO)->size'.
1966 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
1967 inttypes.h, as a gnulib replacement is used if it not available in
1970 2011-04-21 Eli Zaretskii <eliz@gnu.org>

1976 * coding.c (coding_alloc_by_realloc): Error out if destination
1977 will grow beyond MOST_POSITIVE_FIXNUM.
1978 (decode_coding_emacs_mule): Abort if there isn't enough place in
1979 charbuf for the composition carryover bytes. Reserve an extra
1980 space for up to 2 characters produced in a loop.
1981 (decode_coding_iso_2022): Abort if there isn't enough place in
1982 charbuf for the composition carryover bytes.
1984 2011-04-21 Eli Zaretskii <eliz@gnu.org>

1987 aborting when %lld or %lll format is passed.
1988 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
1989 %llo or %llx format is passed. (Bug#8545)
1991 * window.c (window_scroll_line_based): Use a marker instead of
1992 simple variables to record original value of point. (Bug#7952)
1994 * doprnt.c (doprnt): Fix the case where a multibyte sequence
1995 produced by %s or %c overflows available buffer space. (Bug#8545)
1997 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
1999 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
2000 (SIZE_MAX): Move defn after all includes, as they might #define it.
2002 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2004 * w32.c (init_environment): Warn about defaulting HOME to C:\.
2006 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2008 * keyboard.c (Qdelayed_warnings_hook): Define.
2009 (command_loop_1): Run `delayed-warnings-hook'
2010 if Vdelayed_warnings_list is non-nil.
2011 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2012 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2014 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2016 * doprnt.c (doprnt): Don't return value smaller than the buffer
2017 size if the message was truncated. (Bug#8545).
2019 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2021 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
2022 (Fx_window_property): #if-0 the whole functions, not just the bodies.
2024 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2026 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
2028 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
2030 * makefile.w32-in: Update dependencies.
2032 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2034 Improve `doprnt' and its usage. (Bug#8545)
2035 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2036 `format_end'. Remove support for %l as a conversion specifier.
2037 Don't use xrealloc. Improve diagnostics when the %l size modifier
2038 is used. Update the commentary.
2040 * eval.c (verror): Simplify calculation of size_t.
2042 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2045 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)

2050 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2052 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2053 This makes this file independent of the recent pseudovector change.
2055 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2057 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2059 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2060 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2061 Remove unused local.
2062 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2064 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2065 GCC 4.6.0 optimizes based on type-based alias analysis.
2066 For example, if b is of type struct buffer * and v of type struct
2067 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2068 != &v->size, and therefore "v->size = 1; b->size = 2; return
2069 v->size;" must therefore return 1. This assumption is incorrect
2070 for Emacs, since it type-puns struct Lisp_Vector * with many other
2071 types. To fix this problem, this patch adds a new type struct
2072 vectorlike_header that documents the constraints on layout of vectors
2073 and pseudovectors, and helps optimizing compilers not get fooled
2074 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2075 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2076 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2078 (XSETPVECTYPE): Rewrite in terms of new macro.
2079 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2080 This is a bit clearer, and further avoids the possibility of
2081 undesirable aliasing.
2082 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2083 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2084 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2085 since Lisp_Subr is a special case (no "next" field).
2086 (ASIZE): Now uses header.size rather than size.
2087 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2088 to avoid the hassle of writing XVECTOR (foo)->header.size.
2089 (struct vectorlike_header): New type.
2090 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2091 object, to help avoid aliasing.
2092 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2093 (SUBRP): Likewise, since Lisp_Subr is a special case.
2094 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2095 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2096 (struct Lisp_Hash_Table): Combine first two members into a single
2097 struct vectorlike_header member. All uses of "size" and "next" members
2098 changed to be "header.size" and "header.next".
2099 * buffer.h (struct buffer): Likewise.
2100 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2101 * frame.h (struct frame): Likewise.
2102 * process.h (struct Lisp_Process): Likewise.
2103 * termhooks.h (struct terminal): Likewise.
2104 * window.c (struct save_window_data, struct saved_window): Likewise.
2105 * window.h (struct window): Likewise.
2106 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2107 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2108 * buffer.c (init_buffer_once): Likewise.
2109 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2111 * process.c (Fformat_network_address): Use local var for size,
2114 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2116 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2117 * data.c (atof): Remove decl; no longer used or needed.
2118 (digit_to_number): Move to lread.c.
2119 (Fstring_to_number): Use new string_to_number function, to be
2120 consistent with how the Lisp reader treats infinities and NaNs.
2121 Do not assume that floating-point numbers represent EMACS_INT
2122 without losing information; this is not true on most 64-bit hosts.
2123 Avoid double-rounding errors, by insisting on integers when
2124 parsing non-base-10 numbers, as the documentation specifies.
2125 * lisp.h (string_to_number): New decl, replacing ...
2126 (isfloat_string): Remove.
2127 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2128 (read1): Do not accept +. and -. as integers; this
2129 appears to have been a coding error. Similarly, do not accept
2130 strings like +-1e0 as floating point numbers. Do not report
2131 overflow for integer overflows unless the base is not 10 which
2132 means we have no simple and reliable way to continue.
2133 Break out the floating-point parsing into a new
2134 function string_to_number, so that Fstring_to_number parses
2135 floating point numbers consistently with the Lisp reader.
2136 (digit_to_number): Move here from data.c. Make it static inline.
2137 (E_CHAR, EXP_INT): Remove, replacing with ...
2138 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2139 (string_to_number): New function, replacing isfloat_string.
2140 This function checks for valid syntax and produces the resulting
2141 Lisp float number too. Rework it so that string-to-number
2142 no longer mishandles examples like "1.0e+". Use strtoumax,
2143 so that overflow for non-base-10 numbers is reported only when
2144 there's no portable and simple way to convert to floating point.
2146 * textprop.c (set_text_properties_1): Rewrite for clarity,
2147 and to avoid GCC warning about integer overflow.
2149 * intervals.h (struct interval): Use EMACS_INT for members
2150 where EMACS_UINT might cause problems. See
2151 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2152 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2153 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2155 (offset_intervals): Tell GCC not to worry about length overflow
2156 when negating a negative length.
2158 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2159 (overrun_check_free): Likewise.
2161 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2162 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2165 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2166 (gnutls_make_error): Rename local to avoid shadowing.
2167 (gnutls_emacs_global_deinit): ifdef out; not used.
2168 (Fgnutls_boot): Use const for pointer to readonly storage.
2169 Comment out unused local. Fix pointer signedness problems.
2171 * lread.c (openp): Don't stuff size_t into an 'int'.
2172 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2173 about possible signed overflow.
2175 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2176 (GDK_KEY_g): Don't define if already defined.
2177 (xg_prepare_tooltip): Avoid pointer signedness problem.
2178 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2180 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2181 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2183 * xfns.c (Fx_window_property): Simplify a bit,
2184 to make a bit faster and to avoid GCC 4.6.0 warning.
2185 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2187 * fns.c (internal_equal): Don't assume size_t fits in int.
2189 * alloc.c (compact_small_strings): Tighten assertion a little.
2191 Replace pEd with more-general pI, and fix some printf arg casts.
2192 * lisp.h (pI): New macro, generalizing old pEd macro to other
2193 conversion specifiers. For example, use "...%"pI"d..." rather
2194 than "...%"pEd"...".
2195 (pEd): Remove. All uses replaced with similar uses of pI.
2196 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2197 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2198 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2199 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2200 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2201 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2202 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2204 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2205 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2206 * print.c (safe_debug_print, print_object): Likewise.
2207 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2209 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2210 avoiding the 0 flag, which is not portable.
2211 * process.c (Fmake_network_process): Use pI to avoid cast.
2212 * region-cache.c (pp_cache): Likewise.
2213 * xdisp.c (decode_mode_spec): Likewise.
2214 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2215 behavior on 64-bit hosts with printf arg.
2216 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2217 (x_stop_queuing_selection_requests): Likewise.
2218 (x_get_window_property): Don't truncate byte count to an 'int'
2221 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2222 here, since it parses constructs like leading '-' and spaces,
2223 which are not wanted; and it overflows with large numbers.
2224 Instead, simply match F[0-9]+, which is what is wanted anyway.
2226 * alloc.c: Remove unportable assumptions about struct layout.
2227 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2228 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2229 (allocate_vectorlike, make_pure_vector): Use the new macros,
2230 plus offsetof, to remove unportable assumptions about struct layout.
2231 These assumptions hold on all porting targets that I know of, but
2232 they are not guaranteed, they're easy to remove, and removing them
2233 makes further changes easier.
2235 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2236 This doesn't fix a bug but makes the code clearer.
2237 (string_overrun_cookie): Now const. Use initializers that
2238 don't formally overflow signed char, to avoid warnings.
2239 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2240 can cause Emacs to crash when string overrun checking is enabled.
2241 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2242 multiple of sizeof (EMACS_INT); it need not be, if
2243 alignof(EMACS_INT) < sizeof (EMACS_INT).
2244 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2246 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2248 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
2250 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
2252 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
2253 supposed to be handshaking. (Bug#8556)
2254 Reported by Paul Eggert <eggert@cs.ucla.edu>.
2256 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
2258 * lisp.h (Qdebug): List symbol.
2259 * eval.c (Qdebug): Restore global linkage.
2260 * keyboard.c (debug-on-event): New variable.
2261 (handle_user_signal): Break into debugger when debug-on-event
2262 matches the current signal symbol.
2264 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
2266 * alloc.c (check_sblock, check_string_bytes)
2267 (check_string_free_list): Convert to standard C.
2269 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2271 * w32.c (emacs_gnutls_push): Fix typo.
2273 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2275 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2276 "cast to pointer from integer of different size".
2278 Improve doprnt and its use in verror. (Bug#8545)
2279 * doprnt.c (doprnt): Document the set of format control sequences
2280 supported by the function. Use SAFE_ALLOCA instead of always
2283 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2284 is one byte too soon. Don't use xrealloc; instead xfree and
2287 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2289 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
2292 * gnutls.c: Renamed global_initialized to
2293 gnutls_global_initialized. Added internals for the
2294 :verify-hostname-error, :verify-error, and :verify-flags
2295 parameters of `gnutls-boot' and documented those parameters in the
2296 docstring. Start callback support.
2297 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2298 unless a fatal error occured. Call gnutls_alert_send_appropriate
2299 on error. Return error code.
2300 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
2301 (emacs_gnutls_read): Likewise.
2302 (Fgnutls_boot): Return handshake error code.
2303 (emacs_gnutls_handle_error): New function.
2304 (wsaerror_to_errno): Likewise.
2306 * w32.h (emacs_gnutls_pull): Add prototype.
2307 (emacs_gnutls_push): Likewise.

2825 (face_suitable_for_char_p): #if-0, as it's never called.
2826 * fontset.h (face_suitable_for_char_p): Remove decl.
2827 * xfaces.c (face_at_string_position):
2828 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,
2829 since 0 is always ASCII.
2831 * fns.c (weak_hash_tables): Now static.
2833 * fileio.c: Make symbols static if they're not exported.
2834 (auto_saving, auto_save_mode_bits, auto_save_error_occurred):

2852 * editfns.c, lisp.h (get_operating_system_release): Remove.
2853 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
2854 worth the hassle of breaking this out.

2963 so that it's not optimized away.
2964 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
2965 * dispextern.h (bidi_dump_cached_states): Remove, since it's
2966 exported only to the debugger.

2995 * xdisp.c (message_enable_multibyte): Now static.
2997 Declare Lisp_Object Q* variables to be 'static' if not exported.
2998 This makes it easier for human readers (and static analyzers)
2999 to see whether these variables are used from other modules.
3000 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

3011 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
3013 * lisp.h (DEFINE_FUNC): Make sname 'static'.
3015 Make Emacs functions such as Fatom 'static' by default.
3016 This makes it easier for human readers (and static analyzers)
3017 to see whether these functions can be called from other modules.
3018 DEFUN now defines a static function. To make the function external
3019 so that it can be used in other C modules, use the new macro DEFUE.
3020 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
3021 (Finit_image_library):
3022 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

3025 Remove decls, since these functions are now static.
3026 (Funintern, Fget_internal_run_time): New decls, since these functions
3027 were already external.
3029 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

3080 when at ZV. (Bug#8487)
3082 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3084 * charset.c (Fclear_charset_maps): Use xfree instead of free.
3086 * keyboard.c (parse_tool_bar_item): Likewise.
3087 * sound.c (sound_cleanup, alsa_close): Likewise.
3088 * termcap.c (tgetent): Likewise.
3089 * xfns.c (x_default_font_parameter): Likewise.
3090 * xsettings.c (read_and_apply_settings): Likewise.
3092 * alloc.c (overrun_check_malloc, overrun_check_realloc)
3093 (overrun_check_free): Protoize.
3095 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3097 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3098 since callers should never pass a negative size.
3099 Change the signature to match that of plain 'read' and 'write'; see
3100 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3101 * lisp.h: Update prototypes of emacs_write and emacs_read.
3103 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3105 * xdisp.c (redisplay_window): Don't try to determine the character
3106 position of the scroll margin if the window start point w->startp
3107 is outside the buffer's accessible region. (Bug#8468)
3109 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3111 Fix write-region and its subroutines for buffers > 2GB.
3112 * fileio.c (a_write, e_write): Modify declaration of arguments and
3113 local variables to support buffers larger than 2GB.
3114 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3116 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3117 argument, local variables, and return value.
3119 * lisp.h: Update prototypes of emacs_write and emacs_read.
3121 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3123 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3125 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3127 Fix more problems found by GCC 4.6.0's static checks.
3129 * xdisp.c (vmessage): Use a better test for character truncation.
3131 * charset.c (load_charset_map): <, not <=, for optimization,
3132 and to avoid potential problems with integer overflow.
3133 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3134 * casetab.c (set_identity, shuffle): Likewise.
3135 * editfns.c (Fformat): Likewise.
3136 * syntax.c (skip_chars): Likewise.
3138 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3139 This also lets GCC 4.6.0 generate slightly better loop code.
3141 * callint.c (Fcall_interactively): <, not <=, for optimization.
3142 (Fcall_interactively): Count the number of arguments produced,
3143 not the number of arguments given. This is simpler and lets GCC
3144 4.6.0 generate slightly better code.
3146 * ftfont.c: Distingish more carefully between FcChar8 and char.
3147 The previous code passed unsigned char * to a functions like
3148 strlen and xstrcasecmp that expect char *, which does not
3149 conform to the C standard.
3150 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3151 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3152 char * when the C standard requires it.
3154 * keyboard.c (read_char): Remove unused var.
3156 * eval.c: Port to Windows vsnprintf (Bug#8435).
3158 (SIZE_MAX): Define if the headers do not.
3159 (verror): Do not give up if vsnprintf returns a negative count.
3160 Instead, grow the buffer. This ports to Windows vsnprintf, which
3161 does not conform to C99. Problem reported by Eli Zaretskii.
3162 Also, simplify the allocation scheme, by avoiding the need for
3163 calling realloc, and removing the ALLOCATED variable.
3165 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3167 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3168 But keep the doprint source code for now, as we might revamp it
3169 and use it again (Bug#8435).
3170 * lisp.h (doprnt): Remove.
3171 * Makefile.in (base_obj): Remove doprnt.o.
3172 * deps.mk (doprnt.o): Remove.
3174 error: Print 32- and 64-bit integers portably (Bug#8435).
3175 Without this change, on typical 64-bit hosts error ("...%d...", N)
3176 was used to print both 32- and 64-bit integers N, which relied on
3178 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3180 * lisp.h (error, verror): Mark as printf-like functions.
3181 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3182 Report overflow in size calculations when allocating printf buffer.
3183 Do not truncate output string at its first null byte.
3184 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3185 Truncate the output at a character boundary, since vsnprintf does not
3187 * charset.c (check_iso_charset_parameter): Convert internal
3188 character to string before calling 'error', since %c now has the
3190 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3191 overflow when computing char to be passed to 'error'. Do not
3192 pass Lisp_Object to 'error'; pass the integer instead.
3193 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3194 formatted with plain %d.
3196 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3198 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3200 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3202 * xterm.c (x_catch_errors): Remove duplicate declaration.
3204 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3206 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3208 2011-04-10 Jim Meyering <meyering@redhat.com>
3210 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3211 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3212 return ssize_t not "int", and use size_t as the buffer length.
3213 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3214 * gnutls.h: Update declarations.
3215 * process.c (read_process_output): Use ssize_t, to match.
3216 (send_process): Likewise.
3218 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3220 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3222 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3224 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3225 Use unsigned char, to match FcChar8 type definition.
3227 * xterm.c (handle_one_xevent):
3228 * xmenu.c (create_and_show_popup_menu):
3229 * xselect.c (x_decline_selection_request)
3230 (x_reply_selection_request): Avoid type-punned deref of X events.
3232 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3234 Fix some uses of `int' instead of EMACS_INT.
3235 * search.c (string_match_1, fast_string_match)

3285 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3287 * keyboard.c (read_char): Call Lisp function help-form-show,
3288 instead of using internal_with_output_to_temp_buffer.
3289 (Qhelp_form_show): New var.
3290 (syms_of_keyboard): Use DEFSYM macro.
3292 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3294 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3296 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
3298 * process.c (Flist_processes): Remove to Lisp.

3307 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3309 Fix more problems found by GCC 4.6.0's static checks.
3311 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3313 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3315 * lisp.h (message, message_nolog, fatal): Mark as printf-like.

3328 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3330 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3331 This avoids several warnings with gcc -Wstrict-overflow.
3332 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3333 directly, rather than having caller test rule sign. This avoids
3334 some unnecessary tests.
3335 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3336 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3337 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
3339 * xfont.c (xfont_text_extents): Remove var that was set but not used.
3340 (xfont_open): Avoid unnecessary tests.
3342 * composite.c (composition_gstring_put_cache): Use unsigned integer.
3344 * composite.h, composite.c (composition_gstring_put_cache):
3345 Use EMACS_INT, not int, for length.
3347 * composite.h (COMPOSITION_DECODE_REFS): New macro,
3348 breaking out part of COMPOSITION_DECODE_RULE.
3349 (COMPOSITION_DECODE_RULE): Use it.
3350 * composite.c (get_composition_id): Remove unused local vars,
3351 by using the new macro.
3353 * textprop.c (set_text_properties_1): Change while to do-while,
3354 since the condition is always true at first.
3356 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3357 (interval_deletion_adjustment): Return unsigned value.
3360 * process.c (list_processes_1, create_pty, read_process_output):

3362 (create_pty): Remove unnecessary "volatile"s.
3363 (Fnetwork_interface_info): Avoid possibility of int overflow.
3364 (read_process_output): Do adaptive read buffering even if carryover.
3365 (read_process_output): Simplify nbytes computation if buffered.
3367 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
3369 * syntax.c (scan_words): Remove var that was set but not used.
3370 (update_syntax_table): Use unsigned instead of int.

3379 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3381 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3382 (font_score): Avoid potential overflow in diff calculation.
3384 * fns.c (substring_both): Remove var that is set but not used.
3385 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3387 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3389 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3390 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3391 can always succeed if overflow has undefined behavior.
3393 * search.c (boyer_moore, wordify): Remove vars set but not used.
3394 (wordify): Omit three unnecessary tests.
3396 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3397 All callers changed. This avoids the need for an unused var.
3399 * casefiddle.c (casify_region): Remove var that is set but not used.
3401 * dired.c (file_name_completion): Remove var that is set but not used.
3403 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3405 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3406 (Finsert_file_contents): Remove unnecessary code checking fd.
3408 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3409 Check for integer overflow on size calculations.
3411 * buffer.c (Fprevious_overlay_change): Remove var that is set
3414 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3415 Remove vars that are set but not used.
3416 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3417 (timer_check_2): Mark vars as initialized.
3419 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3421 * image.c (lookup_image): Remove var that is set but not used.
3422 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3424 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3425 that are set but not used.
3427 * xfns.c (make_invisible_cursor): Don't return garbage
3428 if XCreateBitmapFromData fails (Bug#8410).
3430 * xselect.c (x_get_local_selection, x_handle_property_notify):
3431 Remove vars that are set but not used.
3433 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3434 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3436 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3437 Remove var that is set but not used.
3438 (scroll_bar_windows_size): Now size_t, not int.
3439 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3442 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3443 (map_tty_color) [!defined MSDOS]: Likewise.
3445 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3447 * coding.c: Remove vars that are set but not used.
3448 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3449 All callers changed.
3450 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3451 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3452 (decode_coding_charset): Remove vars that are set but not used.
3454 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3455 that is set but not used.
3457 * print.c (print_object): Remove var that is set but not used.
3459 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3460 The gnulib version avoids calling malloc in the usual case,
3461 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3462 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3463 * filelock.c (current_lock_owner): Likewise.
3464 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3465 * sysdep.c: Include allocator.h, careadlinkat.h.
3466 (emacs_no_realloc_allocator): New static constant.
3467 (emacs_readlink): New function.
3468 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

3471 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
3473 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
3474 first non-nil return value).
3476 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3478 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3479 if not defined (Bug#8403).
3481 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3483 * xdisp.c (display_count_lines): Remove parameter `start',
3484 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3485 (get_char_face_and_encoding): Remove parameter `multibyte_p',
3486 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3488 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3489 and thereabouts. All callers changed.
3490 (get_per_char_metric): Remove parameter `f', unused since
3491 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
3493 2011-04-02 Jim Meyering <meyering@redhat.com>
3495 do not dereference NULL upon failed strdup
3496 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3497 (ns_get_family): Likewise.
3499 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3501 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
3503 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3505 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3508 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3510 Add lexical binding.
3512 * window.c (Ftemp_output_buffer_show): New fun.
3513 (Fsave_window_excursion):
3514 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3516 * lread.c (lisp_file_lexically_bound_p): New function.
3517 (Fload): Bind Qlexical_binding.
3518 (readevalloop): Remove `evalfun' arg.
3519 Bind Qinternal_interpreter_environment.
3520 (Feval_buffer): Bind Qlexical_binding.
3521 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3523 (syms_of_lread): Declare `lexical-binding'.
3525 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3527 * keyboard.c (eval_dyn): New fun.
3528 (menu_item_eval_property): Use it.
3530 * image.c (parse_image_spec): Use Ffunctionp.
3532 * fns.c (concat, mapcar1): Accept byte-code-functions.
3534 * eval.c (Fsetq): Handle lexical vars.
3535 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3536 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3537 (FletX, Flet): Obey lexical binding.
3538 (Fcommandp): Handle closures.
3539 (Feval): New `lexical' arg.
3540 (eval_sub): New function extracted from Feval. Use it almost
3541 everywhere where Feval was used. Look up vars in lexical env.
3543 (Ffunctionp): Move from subr.el.
3544 (Ffuncall): Handle closures.
3545 (apply_lambda): Remove `eval_flags'.
3546 (funcall_lambda): Handle closures and new byte-code-functions.
3547 (Fspecial_variable_p): New function.
3548 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3549 but without exporting it to Lisp.
3551 * doc.c (Fdocumentation, store_function_docstring):
3552 * data.c (Finteractive_form): Handle closures.
3554 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3557 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3559 (exec_byte_code): New function extracted from Fbyte_code to handle new
3560 calling convention for byte-code-functions. Add new byte-codes.
3562 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3564 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3566 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3568 * xdisp.c (redisplay_internal): Fix prototype.
3570 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3572 * xdisp.c (SCROLL_LIMIT): New macro.
3573 (try_scrolling): Use it when setting scroll_limit.
3574 Limit scrolling to 100 screen lines.
3575 (redisplay_window): Even when falling back on "recentering",
3576 position point in the window according to scroll-conservatively,
3577 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3579 (try_scrolling): When point is above the window, allow searching
3580 as far as scroll_max, or one screenful, to compute vertical
3581 distance from PT to the scroll margin position. This prevents
3582 try_scrolling from unnecessarily failing when
3583 scroll-conservatively is set to a value slightly larger than the
3584 window height. Clean up the case of PT below the margin at bottom
3585 of window: scroll_max can no longer be INT_MAX. When aggressive
3586 scrolling is in use, don't let point enter the opposite scroll
3587 margin as result of the scroll.
3588 (syms_of_xdisp) <scroll-conservatively>: Document the
3589 threshold of 100 lines for never-recentering scrolling.
3591 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3593 * dispextern.h (move_it_by_lines):
3594 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
3595 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
3596 (message_log_check_duplicate): Remove parameters `prev_bol' and
3597 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3598 (redisplay_internal): Remove parameter `preserve_echo_area',
3599 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3601 * indent.c (Fvertical_motion):
3602 * window.c (window_scroll_pixel_based, Frecenter):
3603 Don't pass `need_y_p' to `move_it_by_lines'.
3605 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3607 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3608 steal a few bits to be more compact.
3609 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3610 Remove unneeded casts.
3612 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3614 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3616 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3617 binding" message (bug#7967).
3619 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3621 Fix more problems found by GCC 4.6.0's static checks.
3623 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3624 Remove unused local var.
3626 * editfns.c (Fmessage_box): Remove unused local var.
3628 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3629 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3630 Omit unused local vars.
3631 * window.c (shrink_windows): Omit unused local var.
3632 * menu.c (digest_single_submenu): Omit unused local var.
3633 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3634 Omit unused local var.
3636 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3637 Don't assume string length fits in int.
3638 (keyremap_step, read_key_sequence): Use size_t for sizes.
3639 (read_key_sequence): Don't check last_real_key_start redundantly.
3641 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3642 instead of alloca (Bug#8344).
3644 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3645 (Fbacktrace_frame): Don't assume nframes fits in int.
3647 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
3649 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
3652 * term.c (produce_glyphless_glyph): Remove unnecessary test.
3654 * cm.c (calccost): Turn while-do into do-while, for clarity.
3656 * keyboard.c (syms_of_keyboard): Use the same style as later
3657 in this function when indexing through an array. This also
3658 works around GCC bug 48267.
3660 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3662 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3664 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3665 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3667 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3668 This avoids undefined behavior on integer overflow, and is a bit
3669 more convenient anyway since it is compared to a size_t variable.
3671 Variadic C functions now count arguments with size_t, not int.
3672 This avoids an unnecessary limitation on 64-bit machines, which
3673 caused (substring ...) to crash on large vectors (Bug#8344).
3674 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
3675 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

3679 * editfns.c (general_insert_function): Likewise.
3680 * eval.c (struct backtrace.nargs, interactive_p)
3681 (internal_condition_case_n, run_hook_with_args, apply_lambda)
3682 (funcall_lambda, mark_backtrace): Likewise.
3683 * fns.c (concat): Likewise.
3684 * frame.c (x_set_frame_parameters): Likewise.
3685 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3686 0 if not found, not -1. All callers changed.
3688 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3689 (stack_copy_size): Now size_t, not int.
3690 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3692 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3694 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3695 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3696 All callers changed.
3698 * lisp.h (multibyte_char_to_unibyte):
3699 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
3700 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3701 * character.h (CHAR_TO_BYTE8):
3702 * cmds.c (internal_self_insert):
3703 * editfns.c (general_insert_function):
3704 * keymap.c (push_key_description):
3705 * search.c (Freplace_match):
3706 * xdisp.c (message_dolog, set_message_1): All callers changed.

3896 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
3898 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
3899 unconditionnaly since it does the check itself.
3901 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
3903 Fix more problems found by GCC 4.5.2's static checks.
3905 * coding.c (encode_coding_raw_text): Avoid unnecessary test
3906 the first time through the loop, since we know p0 < p1 then.
3907 This also avoids a gcc -Wstrict-overflow warning.
3909 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
3910 leading to a memory leak, possible in functions like
3911 load_charset_map_from_file that can allocate an unbounded number
3912 of objects (Bug#8318).
3914 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
3915 that could (at least in theory) be that large.
3917 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
3918 This is less likely to overflow, and avoids undefined behavior if

3937 * process.c (Fmake_network_process): Use socklen_t, not int,
3938 where POSIX says socklen_t is required in portable programs.
3939 This fixes a porting bug on hosts like 64-bit HP-UX, where
3940 socklen_t is wider than int (Bug#8277).
3941 (Fmake_network_process, server_accept_connection):
3942 (wait_reading_process_output, read_process_output):

3957 Include tparam.h instead, since it declares them.
3958 * cm.h (PC): Remove extern decl; tparam.h now does this.
3959 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
3960 * terminfo.c: Include tparam.h, to check interfaces.
3961 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
3962 (tparam): Adjust signature to match interface in tparam.h;
3963 this removes some undefined behavior. Check that outstring and len
3964 are zero, which they always are with Emacs.
3965 * tparam.h (PC, BC, UP): New extern decls.
3967 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
3968 (xftfont_open): Rename locals to avoid shadowing.

4010 behavior (Bug#8278).
4012 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4014 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4016 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4017 clobbering (Bug#8298).
4018 * sysdep.c (sys_subshell): Likewise.
4019 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4021 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4022 This should get cleaned up, so that child_setup has the
4023 same signature on all platforms.
4025 * callproc.c (call_process_cleanup): Now static.
4026 (relocate_fd): Rename locals to avoid shadowing.
4028 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4030 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4031 not to be necessary, and produces flickering.

4035 * config.in: Remove file.
4037 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

4088 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4090 * deps.mk (unexalpha.o): Remove; unused.
4092 New file unexec.h, the (simple) interface for unexec (Bug#8267).

4179 Rename locals to avoid shadowing.
4180 (mark_stack): Move local variables into the #ifdef region where
4182 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4183 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4185 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4186 (GC_STRING_CHARS): Remove; not used.
4187 (Fmemory_limit): Cast sbrk's returned value to char *.
4189 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
4190 avoids undefined behavior in theory.
4192 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4194 Use functions, not macros, for up- and down-casing (Bug#8254).
4195 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4196 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4197 to use the following functions instead of these macros.
4198 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4199 EMACS_INT, since callers assume the returned value fits in int.
4200 (upcase1): Likewise, for UPCASE_TABLE.
4201 (uppercasep, lowercasep, upcase): New static inline functions.
4202 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
4203 the race-condition problem in the old DOWNCASE.

4207 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
4208 (regex_compile, re_search_2, re_match_2_internal):
4209 Remove unused local vars.
4210 (FREE_VAR): Rewrite so as not to use empty "else",
4211 which gcc can warn about.
4212 (regex_compile, re_match_2_internal): Mark locals as initialized.
4213 (RETALLOC_IF): Define only if needed.
4214 (WORDCHAR_P): Likewise. This one is never needed, but is used
4215 only in a comment talking about a compiler bug, so put inside
4216 the #if 0 of that comment.
4217 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4218 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4221 * search.c (boyer_moore): Rename locals to avoid shadowing.
4222 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4223 (PREV_CHAR_BOUNDARY): Likewise.

4239 * casefiddle.c (casify_object, casify_region): Now static.
4240 (casify_region): Mark local as initialized.
4242 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4244 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4245 New macros, so that the caller can use some names other than
4246 gcpro1, gcpro2, etc.
4247 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4249 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4250 argument, for consistency with GCPRO2_VAR, etc: it is now the
4251 prefix of the variable, not the variable itself. All uses
4253 * dired.c (directory_files_internal, file_name_completion):
4254 Rename locals to avoid shadowing.
4256 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4257 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4258 dired.c's scmp function, had undefined behavior.
4259 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4260 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4261 * buffer.h: ... to here, because these macros use current_buffer,
4262 and the new implementation with inline functions needs to have
4263 current_buffer in scope now, rather than later when the macros
4265 (downcase, upcase1): New static inline functions.
4266 (DOWNCASE, UPCASE1): Reimplement using these functions.
4267 This avoids undefined behavior in expressions like
4268 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4269 from race conditions in accessing the global variables
4270 case_temp1 and case_temp2.
4271 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4272 * lisp.h (case_temp1, case_temp2): Remove their decls.
4273 * character.h (ASCII_CHAR_P): Move from here ...
4274 * lisp.h: ... to here, so that the inline functions mentioned
4277 * dired.c (directory_files_internal_unwind): Now static.
4279 * fileio.c (file_name_as_directory, directory_file_name):
4280 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4282 (file_name_as_directory): Use const pointers when appropriate.
4283 (Fexpand_file_name): Likewise. In particular, newdir might
4284 point at constant storage, so make it a const pointer.
4285 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4286 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4288 (Fset_file_times, Finsert_file_contents, auto_save_error):

4297 * lisp.h (verify_bytepos, count_markers): New decls,
4298 so that gcc does not warn that these functions aren't declared.
4300 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4301 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4302 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4303 (copy_text): Remove unused local var.
4305 * filelock.c (within_one_second): Now static.
4306 (lock_file_1): Rename local to avoid shadowing.
4308 * buffer.c (fix_overlays_before): Mark locals as initialized.
4309 (fix_start_end_in_overlays): Likewise. This function should be
4310 simplified by using pointers-to-pointers, but that's a different
4312 (switch_to_buffer_1): Now static.
4313 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4314 (report_overlay_modification): Rename locals to avoid shadowing.
4316 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
4317 Fix pointer signedness issue.
4318 (sys_subshell): Mark local as volatile if checking for lint,
4319 to suppress a gcc -Wclobbered warning that does not seem to be right.
4320 (MAXPATHLEN): Define only if needed.
4322 * process.c (serial_open, serial_configure): Move decls from here ...
4323 * systty.h: ... to here, so that they can be checked.
4325 * fns.c (get_random, seed_random): Move extern decls from here ...
4326 * lisp.h: ... to here, so that they can be checked.
4328 * sysdep.c (reset_io): Now static.
4329 (wait_for_termination_signal): Remove; unused.
4331 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
4332 (copy_keymap_item, append_key, push_text_char_description):
4334 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.

4341 (echo_char, echo_dash, cmd_error, top_level_2):
4342 (poll_for_input, handle_async_input): Now static.
4343 (read_char, kbd_buffer_get_event, make_lispy_position):

4682 -Wuninitialized does not deduce are never used uninitialized.
4683 (detect_coding_iso_2022): Initialize a local variable that might

4718 Move these decls to tparam.h, and make them agree with what
