117 * print.c (printchar, strout): Check for string overflow.
118 (PRINTPREPARE, printchar, strout):
119 Don't set size unless allocation succeeds.
121 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
122 for sizes. Check for string overflow more accurately.
123 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
125 * macros.c: Integer and buffer overflow fixes.
126 * keyboard.h (struct keyboard.kbd_macro_bufsize):
127 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
128 Use ptrdiff_t, not int, for sizes.

130 Check for size-calculation overflow.
131 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
133 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
135 * lread.c: Integer overflow fixes.
136 (read_integer): Radix is now EMACS_INT, not int,
137 to improve quality of diagnostics for out-of-range radices.
138 Calculate buffer size correctly for out-of-range radices.
139 (read1): Check for integer overflow in radices, and in
141 (read_escape): Avoid int overflow.
142 (Fload, openp, read_buffer_size, read1)
143 (substitute_object_recurse, read_vector, read_list, map_obarray):

155 out-of-range doc string lengths.
156 (read_list): Don't assume file position fits in int.
157 (read_escape): Check for hex character overflow.
159 2011-06-22 Leo Liu <sdl.web@gmail.com>
161 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
162 Move to minibuffer.el.
164 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
166 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
167 The following patches are for when GLYPH_DEBUG && !XASSERT.
168 * dispextern.h (trace_redisplay_p, dump_glyph_string):
169 * dispnew.c (flush_stdout):
170 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
171 Mark as externally visible.
172 * dispnew.c (check_window_matrix_pointers): Now static.
173 * dispnew.c (window_to_frame_vpos):
174 * xfns.c (unwind_create_frame):
175 * xterm.c (x_check_font): Remove unused local.
176 * scroll.c (CHECK_BOUNDS):
177 * xfaces.c (cache_fache): Rename local to avoid shadowing.
178 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
179 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
180 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
181 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
183 (debug_method_add): Use va_list and vsprintf rather than relying
184 on undefined behavior with wrong number of arguments.
185 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
186 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
187 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
188 since we're not interested in debugging glyphs with old libraries.
189 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
190 GCC 4.6.0's static checking.
192 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
194 Integer overflow and signedness fixes (Bug#8873).
195 A few related buffer overrun fixes, too.
197 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
199 * dispextern.h (struct face.stipple):
200 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
201 (x_bitmap_mask, x_allocate_bitmap_record)
202 (x_create_bitmap_from_data, x_create_bitmap_from_file)
203 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
204 (x_create_bitmap_from_xpm_data):
205 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
206 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
208 * xfaces.c (load_pixmap):
209 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
210 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
211 (.bitmaps_last, struct x_output.icon_bitmap):
212 Use ptrdiff_t, not int, for bitmap indexes.
213 (x_allocate_bitmap_record): Check for size overflow.
214 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
216 Use ptrdiff_t, not int, for overlay counts.
217 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
218 * editfns.c (overlays_around, get_pos_property):
219 * textprop.c (get_char_property_and_overlay):
220 * xdisp.c (next_overlay_change, note_mouse_highlight):
221 * xfaces.c (face_at_buffer_position):
222 * buffer.c (OVERLAY_COUNT_MAX): New macro.
223 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
224 (Fnext_overlay_change, Fprevious_overlay_change)
225 (mouse_face_overlay_overlaps, Foverlays_in):
226 Use ptrdiff_t, not int, for sizes.

229 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
231 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
232 (x_session_initialize): Do not assume string length fits in int.
234 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
235 This is unlikely, but can occur if DPI is outlandish.
237 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
238 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
240 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
241 * xrdb.c (magic_file_p, search_magic_path):
242 Omit last arg SUFFIX; it was always 0. All callers changed.

245 * xfont.c (xfont_match): Avoid need for strlen.
247 * xfns.c: Don't assume strlen fits in int.
248 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
250 * xdisp.c (message_log_check_duplicate): Return intmax_t,
251 not unsigned long, as we prefer signed integers. All callers changed.
252 Detect integer overflow in repeat count.
253 (message_dolog): Don't assume print length fits in 39 bytes.
254 (display_mode_element): Don't assume strlen fits in int.
256 * termcap.c: Don't assume sizes fit in int and never overflow.
257 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
258 (gobble_line): Check for size-calculation overflow.
260 * minibuf.c (Fread_buffer):
261 * lread.c (intern, intern_c_string):
262 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
263 Don't assume string length fits in int.
265 * keyboard.c (parse_tool_bar_item):
266 * gtkutil.c (style_changed_cb): Avoid need for strlen.
268 * font.c: Don't assume string length fits in int.
269 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
270 Use ptrdiff_t, not int.
271 (font_intern_prop): Don't assume string length fits in int.
272 Don't assume integer property fits in fixnum.
273 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
275 * filelock.c: Fix some buffer overrun and integer overflow issues.
276 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
277 Reformulate so as not to need the command string.
278 Invoke gzip -cd rather than gunzip, as it's more portable.
279 (lock_info_type, lock_file_1, lock_file):
280 Don't assume pid_t and time_t fit in unsigned long.
281 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
282 (current_lock_owner): Prefer signed type for sizes.
283 Use memcpy, not strncpy, where memcpy is what is really wanted.
284 Don't assume (via atoi) that time_t and pid_t fit in int.
285 Check for time_t and/or pid_t out of range, e.g., via a network share.
286 Don't alloca where an auto var works fine.
288 * fileio.c: Fix some integer overflow issues.
289 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
290 Don't assume string length fits in int.
291 (directory_file_name): Don't assume string length fits in long.
292 (make_temp_name): Don't assume pid fits in int, or that its print
293 length is less than 20.
295 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
297 * coding.c (make_subsidiaries): Don't assume string length fits in int.
299 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
301 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
302 We prefer signed integers, even for size calculations.
304 * emacs.c: Don't assume string length fits in 'int'.
305 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
306 (main): Don't invoke strlen when not needed.

311 * callproc.c (getenv_internal_1, getenv_internal)
313 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
315 * lread.c (invalid_syntax): Omit length argument.
316 All uses changed. This doesn't fix a bug, but it simplifies the
317 code away from its former Hollerith-constant appearance, and it's
318 one less 'int' to worry about when looking at integer-overflow issues.
319 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
321 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
322 This didn't break anything, but it didn't help either.
323 It's confusing to put a bogus integer in a place where the actual
324 value does not matter.
325 (LIST_END_P): Remove unused macro and its bogus comment.
326 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
328 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
329 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
331 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
332 We prefer signed types, and the value cannot exceed the EMACS_INT
333 range anyway (because otherwise the length would not be representable).
334 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
335 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
336 This avoids a GCC warning when WIDE_EMACS_INT.
338 * indent.c (sane_tab_width): New function.
339 (current_column, scan_for_column, Findent_to, position_indentation)
340 (compute_motion): Use it. This is just for clarity.
341 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
343 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
345 * lisp.h (lint_assume): New macro.
346 * composite.c (composition_gstring_put_cache):
347 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
349 * editfns.c, insdel.c:
350 Omit unnecessary forward decls, to simplify future changes.
352 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
354 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
356 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
357 Use much-faster test for byte-length change.
358 Don't assume string byte-length fits in 'int'.
359 Check that character arg fits in 'int'.
360 (mapcar1): Declare byte as byte, for clarity.
362 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
364 * fns.c (concat): Catch string overflow earlier.
365 Do not rely on integer wraparound.
367 * dispextern.h (struct it.overlay_strings_charpos)
368 (struct it.selective): Now EMACS_INT, not int.
369 * xdisp.c (forward_to_next_line_start)
370 (back_to_previous_visible_line_start)
371 (reseat_at_next_visible_line_start, next_element_from_buffer):
372 Don't arbitrarily truncate the value of 'selective' to int.
374 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
376 * composite.c: Don't truncate sizes to 'int'.
377 (composition_gstring_p, composition_reseat_it)
378 (composition_adjust_point): Use EMACS_INT, not int.
379 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
380 not EMACS_UINT, for indexes.
382 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
384 * buffer.c: Include <verify.h>.
385 (struct sortvec.priority, struct sortstr.priority):
386 Now EMACS_INT, not int.
387 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
388 (struct sortstr.size, record_overlay_string)
389 (struct sortstrlist.size, struct sortlist.used):
390 Don't truncate size to int.
391 (record_overlay_string): Check for size-calculation overflow.
392 (init_buffer_once): Check at compile-time, not run-time.
394 2011-06-22 Jim Meyering <meyering@redhat.com>
396 Don't leak an XBM-image-sized buffer
397 * image.c (xbm_load): Free the image buffer after using it.
399 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
402 * composite.c (find_automatic_composition): Omit needless 'return 0;'
403 that Sun C diagnosed.
404 * fns.c (secure_hash): Fix pointer signedness issue.
405 * intervals.c (static_offset_intervals): New function.
406 (offset_intervals): Use it.
408 2011-06-21 Leo Liu <sdl.web@gmail.com>
411 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
414 * fns.c (secure_hash): Rename from crypto_hash_function and change
415 the first arg to accept symbols.
416 (Fsecure_hash): New primitive.
417 (syms_of_fns): New symbols.
419 2011-06-20 Deniz Dogan <deniz@dogan.se>
421 * process.c (Fset_process_buffer): Clarify return value in
424 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
426 * dispnew.c (add_window_display_history): Use BVAR.
428 * xdisp.c (debug_method_add): Use BVAR.
429 (check_window_end, dump_glyph_matrix, dump_glyph)
430 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
432 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
435 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
436 check till after the cache is created in init_frame_faces.
438 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
440 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
442 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
444 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
445 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
446 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
448 Improve buffer-overflow checking (Bug#8873).
449 * fileio.c (Finsert_file_contents):
450 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
451 Remove the old (too-loose) buffer overflow checks.
452 They weren't needed, since make_gap checks for buffer overflow.
453 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
454 The old code merely checked for Emacs fixnum overflow, and relied
455 on undefined (wraparound) behavior. The new code avoids undefined
456 behavior, and also checks for ptrdiff_t and/or size_t overflow.
458 * editfns.c (Finsert_char): Don't dump core with very negative counts.
459 Tune. Don't use wider integers than needed. Don't use alloca.
460 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
462 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
464 * insdel.c, lisp.h (buffer_overflow): New function.
465 (insert_from_buffer_1, replace_range, replace_range_2):
466 * insdel.c (make_gap_larger):
467 * editfns.c (Finsert_char):
468 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
470 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
472 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
474 Integer overflow and signedness fixes (Bug#8873).
476 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
477 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
479 * fileio.c: Don't assume EMACS_INT fits in off_t.
480 (emacs_lseek): New static function.
481 (Finsert_file_contents, Fwrite_region): Use it.
482 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
484 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
486 * fns.c: Don't overflow int when computing a list length.
487 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
488 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
489 truncation on 64-bit hosts. Check for QUIT every
490 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
491 faster and is responsive enough.
492 (Flength): Report an error instead of overflowing an integer.
493 (Fsafe_length): Return a float if the value is not representable
494 as a fixnum. This shouldn't happen except in contrived situations.
495 (Fnthcdr, Fsort): Don't assume list length fits in int.
496 (Fcopy_sequence): Don't assume vector length fits in int.
498 * alloc.c: Check that resized vectors' lengths fit in fixnums.
499 (header_size, word_size): New constants.
500 (allocate_vectorlike): Don't check size overflow here.
501 (allocate_vector): Check it here instead, since this is the only
502 caller of allocate_vectorlike that could cause overflow.
503 Check that the new vector's length is representable as a fixnum.
505 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
506 The previous code was bogus. For example, next_almost_prime (32)
507 returned 39, which is undesirable as it is a multiple of 3; and
508 next_almost_prime (24) returned 25, which is a multiple of 5 so
509 why was the code bothering to check for multiples of 7?
511 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
513 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
515 Variadic C functions now count arguments with ptrdiff_t.
516 This partly undoes my 2011-03-30 change, which replaced int with size_t.
517 Back then I didn't know that the Emacs coding style prefers signed int.
518 Also, in the meantime I found a few more instances where arguments
519 were being counted with int, which may truncate counts on 64-bit
520 machines, or EMACS_INT, which may be unnecessarily wide.
521 * lisp.h (struct Lisp_Subr.function.aMANY)
522 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
523 Arg counts are now ptrdiff_t, not size_t.
524 All variadic functions and their callers changed accordingly.
525 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
526 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
527 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
528 * callint.c (Fcall_interactively): Check arg count for overflow,
529 to avoid potential buffer overrun. Use signed char, not 'int',
530 for 'varies' array, so that we needn't bother to check its size
531 calculation for overflow.
532 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
533 * eval.c (apply_lambda):
534 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
535 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
536 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
538 * callint.c (Fcall_interactively): Don't use index var as event count.
540 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
541 * mem-limits.h (SIZE): Remove; no longer used.
543 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
545 Remove unnecessary casts.
546 * xterm.c (x_term_init):
547 * xfns.c (x_set_border_pixel):
548 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
549 These aren't needed now that we assume ANSI C.
551 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
552 It's more likely to cause problems (due to unsigned overflow)
555 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
557 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
559 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
561 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
563 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
565 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
567 GLYPH_CODE_FACE returns EMACS_INT, not int.
568 * dispextern.h (merge_faces):
569 * xfaces.c (merge_faces):
570 * xdisp.c (get_next_display_element, next_element_from_display_vector):
571 Don't assume EMACS_INT fits in int.
573 * character.h (CHAR_VALID_P): Remove unused parameter.
574 * fontset.c, lisp.h, xdisp.c: All uses changed.
576 * editfns.c (Ftranslate_region_internal): Omit redundant test.
578 * fns.c (concat): Minor tuning based on overflow analysis.
579 This doesn't fix any bugs. Use int to hold character, instead
580 of constantly refetching from Emacs object. Use XFASTINT, not
581 XINT, for value known to be a character. Don't bother comparing
582 a single byte to 0400, as it's always less.
584 * floatfns.c (Fexpt):
585 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
587 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
590 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
592 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
593 Without this fix, on a 64-bit host (aset S 0 4294967386) would
594 incorrectly succeed when S was a string, because 4294967386 was
595 truncated before it was used.
597 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
598 Otherwise, an out-of-range integer could cause undefined behavior
601 * composite.c: Use int, not EMACS_INT, for characters.
602 (fill_gstring_body, composition_compute_stop_pos): Use int, not
603 EMACS_INT, for values that are known to be in character range.
604 This doesn't fix any bugs but is the usual style inside Emacs and
605 may generate better code on 32-bit machines.
607 Make sure a 64-bit char is never passed to ENCODE_CHAR.
608 This is for reasons similar to the recent CHAR_STRING fix.
609 * charset.c (Fencode_char): Check that character arg is actually
610 a character. Pass an int to ENCODE_CHAR.
611 * charset.h (ENCODE_CHAR): Verify that the character argument is no
612 wider than 'int', as a compile-time check to prevent future regressions
615 * character.c (char_string): Remove unnecessary casts.
617 Make sure a 64-bit char is never passed to CHAR_STRING.
618 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
619 by silently ignoring the top 32 bits, allowing some values
620 that were far too large to be valid characters.
621 * character.h: Include <verify.h>.
622 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
623 arguments are no wider than unsigned, as a compile-time check
624 to prevent future regressions in this area.
626 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
627 (Fsubst_char_in_region):
629 * xdisp.c (decode_mode_spec_coding):
630 Adjust to CHAR_STRING's new requirement.
631 * editfns.c (Finsert_char, Fsubst_char_in_region):
632 * fns.c (concat): Check that character args are actually
633 characters. Without this test, these functions did the wrong
634 thing with wildly out-of-range values on 64-bit hosts.
636 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
637 These casts should not be needed on 32-bit hosts, either.
638 * keyboard.c (read_char):
639 * lread.c (Fload): Remove casts to unsigned.
641 * lisp.h (UNSIGNED_CMP): New macro.
642 This fixes comparison bugs on 64-bit hosts.
643 (ASCII_CHAR_P): Use it.
644 * casefiddle.c (casify_object):
645 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
646 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
647 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
648 * dispextern.h (FACE_FROM_ID):
649 * keyboard.c (read_char): Use UNSIGNED_CMP.
651 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
652 not to EMACS_INT, to avoid GCC warning.
654 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
656 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
657 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
658 isn't needed on 32-bit machines.
660 * buffer.c (Fgenerate_new_buffer_name):
661 Use EMACS_INT for count, not int.
662 (advance_to_char_boundary): Return EMACS_INT, not int.
664 * data.c (Qcompiled_function): Now static.
666 * window.c (window_body_lines): Now static.
668 * image.c (gif_load): Rename local to avoid shadowing.
670 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
671 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
672 * alloc.c (make_save_value): Integer argument is now of type
674 (mark_object): Use ptrdiff_t, not int.
675 * lisp.h (pD): New macro.
676 * print.c (print_object): Use it.
678 * alloc.c: Use EMACS_INT, not int, to count objects.
679 (total_conses, total_markers, total_symbols, total_vector_size)
680 (total_free_conses, total_free_markers, total_free_symbols)
681 (total_free_floats, total_floats, total_free_intervals)
682 (total_intervals, total_strings, total_free_strings):
683 Now EMACS_INT, not int. All uses changed.
684 (Fgarbage_collect): Compute overall total using a double, so that
685 integer overflow is less likely to be a problem. Check for overflow
686 when converting back to an integer.
687 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
688 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
689 These were 'int' variables that could overflow on 64-bit hosts;
690 they were never used, so remove them instead of repairing them.
691 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
692 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
693 Previously, this ceilinged at INT_MAX, but that doesn't work on
695 (allocate_pseudovector): Don't use EMACS_INT when int would do.
697 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
698 (allocate_vectorlike): Check for ptrdiff_t overflow.
699 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
700 when a (possibly-narrower) signed value would do just as well.
701 We prefer using signed arithmetic, to avoid comparison confusion.
703 * alloc.c: Catch some string size overflows that we were missing.
704 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
705 for convenience in STRING_BYTES_MAX.
706 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
707 The definition here is exact; the one in lisp.h was approximate.
708 (allocate_string_data): Check for string overflow. This catches
709 some instances we weren't catching before. Also, it catches
710 size_t overflow on (unusual) hosts where SIZE_MAX <= min
711 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
712 and ptrdiff_t and EMACS_INT are both 64 bits.
714 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
715 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
716 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
718 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
720 * alloc.c (Fmake_string): Check for out-of-range init.
722 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
724 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
726 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
728 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
729 xg_get_default_scrollbar_width.
731 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
732 (int_gtk_range_get_value): Move to the scroll bar part of the file.
733 (style_changed_cb): Call update_theme_scrollbar_width and call
734 x_set_scroll_bar_default_width and xg_frame_set_char_size for
735 all frames (Bug#8505).

737 Call gtk_window_set_resizable if HAVE_GTK3.
738 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
739 and height if HAVE_GTK3 (Bug#8505).
740 (scroll_bar_width_for_theme): New variable.
741 (update_theme_scrollbar_width): New function.
742 (xg_get_default_scrollbar_width): Move code to
743 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
744 (xg_initialize): Call update_theme_scrollbar_width.
746 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
748 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
750 2011-06-12 Martin Rudalics <rudalics@gmx.at>
752 * frame.c (make_frame): Call other_buffer_safely instead of
755 * window.c (temp_output_buffer_show): Call display_buffer with
756 second argument Vtemp_buffer_show_specifiers and reset latter
757 immediately after the call.
758 (Vtemp_buffer_show_specifiers): New variable.
759 (auto_window_vscroll_p, next_screen_context_lines)
760 (Vscroll_preserve_screen_position): Remove leading asterisks from

767 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
768 (record_buffer): Remove unused local.
769 * frame.c (other_visible_frames, frame_buffer_list): Now static.

788 the same widths as pointers. This follows up on the 2011-05-06 patch.
789 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
791 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.

828 buffer list implementation.
829 (other_buffer_safely): New function.
830 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
831 calls to replace_buffer_in_windows and
832 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
834 (record_buffer): Inhibit quitting and rewrite using quittable
835 functions. Run Qbuffer_list_update_hook if allowed.

861 moved into replace_buffer_in_windows_safely.
862 (replace_buffer_in_windows_safely): New function.
863 (select_window_norecord, select_frame_norecord): Move in front
864 of run_window_configuration_change_hook. Remove now obsolete
866 (Fset_window_buffer): Rewrite doc-string. Call
867 Qrecord_window_buffer.
868 (keys_of_window): Move binding for other-window to window.el.

1356 * gnutls.c: Use Emacs's memory allocators.
1357 Without this change, the gnutls library would invoke malloc etc.
1358 directly, which causes problems on non-SYNC_INPUT hosts, and which
1359 runs afoul of improving memory_full behavior. (Bug#8761)
1360 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
1361 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1362 xfree instead of the default malloc, realloc, free.
1363 (Fgnutls_boot): No need to check for memory allocation failure,
1364 since xmalloc does that for us.

1389 Check for overflow in vector size calculations.
1390 * ccl.c (ccl_driver):
1391 Check for overflow when converting EMACS_INT to int.
1392 * fns.c, image.c: Remove unnecessary static decls that would otherwise
1393 need to be updated by these changes.
1394 * fns.c (make_hash_table, maybe_resize_hash_table):
1395 Check for integer overflow with large hash tables.
1396 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
1397 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
1398 (SXHASH_REDUCE): New macro.
1399 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
1400 Use it instead of discarding useful hash info with large hash values.
1401 (sxhash_float): New function.
1402 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1403 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1404 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1405 Rewrite to use FIXNUM_BITS, as this simplifies things.
1406 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1407 Adjust signatures to match updated version of code.
1408 (consing_since_gc): Now EMACS_INT, since a single hash table can
1409 use more than INT_MAX bytes.

1422 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1424 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1425 Update dependencies.
1427 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1429 * data.c (init_data): Remove code for UTS, this system is not
1432 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1434 Don't force ./temacs to start in terminal mode.
1436 * frame.c (make_initial_frame): Initialize faces in all cases, not
1437 only when CANNOT_DUMP is defined.
1438 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1440 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1442 * dispnew.c (add_window_display_history): Use const for the string
1443 pointer. Remove declaration, not needed.
1445 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1447 Use 'inline', not 'INLINE'.
1448 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1449 * alloc.c, fontset.c (INLINE): Remove.
1450 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1451 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1452 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1453 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1454 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1456 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1458 Make it possible to run ./temacs.
1460 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1461 syms_of_callproc does the same thing. Remove test for
1462 "initialized", do it in the caller.
1463 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1465 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1467 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1468 (read_minibuf): Use get_minibuffer.
1469 (syms_of_minibuf): Use DEFSYM.
1470 (Qmetadata): New var.
1471 * data.c (Qbuffer): Don't make it static.
1472 (syms_of_data): Use DEFSYM.
1474 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1476 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1477 (CCL_CODE_MIN): New macro.
1479 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1481 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1483 * eval.c (Qdebug): Now static.
1484 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1485 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1486 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1488 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1490 * image.c: Various fixes to ImageMagick code comments.
1491 (Fimagemagick_types): Doc fix.
1493 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1495 Minor fixes prompted by GCC 4.6.0 warnings.
1497 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1499 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1500 (x_clipboard_manager_save_all): Move extern decl to ...
1501 * xterm.h: ... here, so that it can be checked for consistency.
1503 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1505 * xselect.c (x_clipboard_manager_save_frame)
1506 (x_clipboard_manager_save_all): New functions.
1507 (Fx_clipboard_manager_save): Lisp function deleted.
1509 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1510 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1512 * xterm.h: Update prototype.
1514 2011-05-28 William Xu <william.xwl@gmail.com>
1516 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1519 2011-05-28 Jim Meyering <meyering@redhat.com>
1521 Avoid a sign-extension bug in crypto_hash_function.
1522 * fns.c (to_uchar): Define.
1523 (crypto_hash_function): Use it to convert some newly-signed
1524 variables to unsigned, to avoid sign-extension bugs. For example,
1525 without this change, (md5 "truc") would evaluate to
1526 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1527 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1528 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1530 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1532 Integer overflow fixes.
1534 * dbusbind.c: Serial number integer overflow fixes.
1535 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1536 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1537 to hold a serial number that is too large for a fixnum.
1538 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1539 Check for serial numbers out of range. Decode any serial number
1540 that was so large that it became a float. (Bug#8722)
1542 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1543 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1544 Use XFASTINT rather than XUINT when numbers are nonnegative.
1545 (xd_append_arg, Fdbus_method_return_internal):
1546 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1547 arguments, check that Lisp number is nonnegative, rather than
1548 silently wrapping negative numbers around. (Bug#8722)
1549 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1552 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1554 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1556 ccl: add integer overflow checks
1557 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1558 (IN_INT_RANGE): New macros.
1559 (ccl_driver): Use them to check for integer overflow when
1560 decoding a CCL program. Many of the new checks are whether XINT (x)
1561 fits in int; it doesn't always, on 64-bit hosts. The new version
1562 doesn't catch all possible integer overflows, but it's an
1563 improvement. (Bug#8719)
1565 * alloc.c (make_event_array): Use XINT, not XUINT.
1566 There's no need for unsigned here.
1568 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1569 This follows up to the 2011-05-06 change that substituted uintptr_t
1570 for EMACS_INT. This case wasn't caught back then.
1572 Rework Fformat to avoid integer overflow issues.
1573 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1574 now (part of C89). Include <verify.h>.
1575 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1576 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1577 (Fformat): Avoid the prepass trying to compute sizes; it was only
1578 approximate and thus did not catch overflow reliably. Instead, walk
1579 through the format just once, formatting and computing sizes as we go,
1580 checking for integer overflow at every step, and allocating a larger
1581 buffer as needed. Keep track separately whether the format is
1582 multibyte. Keep only the most-recently calculated precision, rather
1583 than them all. Record whether each argument has been converted to
1584 string. Use EMACS_INT, not int, for byte and char and arg counts.
1585 Support field widths and precisions larger than INT_MAX. Avoid
1586 sprintf's undefined behavior with conversion specifications such as %#d
1587 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1588 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1589 formatting out-of-range floating point numbers with int
1592 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1594 * data.c: Avoid integer truncation in expressions involving floats.
1595 * data.c: Include <intprops.h>.
1596 (arith_driver): When there's an integer overflow in an expression
1597 involving floating point, convert the integers to floating point
1598 so that the resulting value does not suffer from catastrophic
1599 integer truncation. For example, on a 64-bit host (* 4
1600 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1601 Do not rely on undefined behavior after integer overflow.
1603 merge count_size_as_multibyte, parse_str_to_multibyte
1604 * character.c, character.h (count_size_as_multibyte):
1605 Rename from parse_str_to_multibyte; all uses changed.
1606 Check for integer overflow.
1607 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1608 since it's now a duplicate of the other. This is more of
1609 a character than a buffer op, so better that it's in character.c.
1610 * fns.c, print.c: Adjust to above changes.
1612 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1614 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1616 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1618 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1619 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1620 (x_clipboard_manager_save): Now static.
1621 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1623 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1624 (crypto_hash_function): Now static.
1625 Fix pointer signedness problems. Avoid unnecessary initializations.
1627 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1629 * termhooks.h (Vselection_alist): Make it terminal-local.
1631 * terminal.c (create_terminal): Initialize it.
1633 * xselect.c: Support for clipboard managers.
1634 (Vselection_alist): Move to termhooks.h as terminal-local var.
1635 (LOCAL_SELECTION): New macro.
1636 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1637 (symbol_to_x_atom): Remove gratuitous arg.
1638 (x_handle_selection_request, lisp_data_to_selection_data)
1639 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1640 (x_own_selection, x_get_local_selection, x_convert_selection):
1641 New arg, specifying work frame. Use terminal-local Vselection_alist.
1642 (some_frame_on_display): Delete unused function.
1643 (Fx_own_selection_internal, Fx_get_selection_internal)
1644 (Fx_disown_selection_internal, Fx_selection_owner_p)
1645 (Fx_selection_exists_p): New optional frame arg.
1646 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1647 (x_handle_selection_clear): Don't treat other terminals with the
1648 same keyboard specially. Use the terminal-local Vselection_alist.
1649 (x_clear_frame_selections): Use Frun_hook_with_args.
1651 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1653 * xterm.h: Add support for those atoms.
1655 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1657 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1658 (converted_selections, conversion_fail_tag): New global variables.
1659 (x_selection_request_lisp_error): Free the above.
1660 (x_get_local_selection): Remove unnecessary code.
1661 (x_reply_selection_request): Args changed; handle arbitrary array
1662 of converted selections stored in converted_selections.
1663 Separate the XChangeProperty and SelectionNotify steps.
1664 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1665 (x_convert_selection): New function.
1666 (x_handle_selection_event): Simplify.
1667 (x_get_foreign_selection): Don't ignore incoming requests while
1668 waiting for an answer; this will fail when we implement
1669 SAVE_TARGETS, and seems unnecessary anyway.
1670 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1671 (Vx_sent_selection_functions): Doc fix.
1673 2011-05-26 Leo Liu <sdl.web@gmail.com>
1675 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1677 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1679 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1681 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1682 for fringe update if it has periodic bitmap.
1683 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1684 and fringe_bitmap_periodic_p.
1686 * fringe.c (get_fringe_bitmap_data): New function.
1687 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1688 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1689 row. Mark glyph row for fringe update if periodicity changed.
1691 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1692 for fringe update unless it has periodic bitmap.
1694 2011-05-25 Kenichi Handa <handa@m17n.org>
1696 * xdisp.c (get_next_display_element): Set correct it->face_id for
1697 a static composition.
1699 2011-05-24 Leo Liu <sdl.web@gmail.com>
1702 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1704 * fns.c (crypto_hash_function, Fsha1): New function.
1705 (Fmd5): Use crypto_hash_function.
1706 (syms_of_fns): Add Ssha1.
1708 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1710 * gnutls.c: Remove unused macros.
1711 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1712 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1713 Remove macros that are defined and never used.
1714 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1716 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1718 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1719 (Fx_get_selection_internal): Minor cleanup.
1720 (Fx_own_selection_internal): Rename arguments for consistency with
1723 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1725 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1727 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1729 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1731 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1733 * dispnew.c (scrolling_window): Don't exclude the case that the
1734 last enabled row in the desired matrix touches the bottom boundary.
1736 2011-05-21 Glenn Morris <rgm@gnu.org>
1738 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1739 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1740 and add some more files.
1742 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1744 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1745 report_file_error introduced by the change from 2011-05-07.
1747 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1749 * systime.h (Time): Define only if emacs is defined.
1750 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1751 where the include path doesn't have X11/X.h by default. See
1752 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1754 2011-05-20 Kenichi Handa <handa@m17n.org>
1756 * composite.c (find_automatic_composition): Fix previous change.
1758 2011-05-20 Glenn Morris <rgm@gnu.org>
1760 * lisp.mk: New file, split from Makefile.in.
1761 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1762 (shortlisp): Remove.
1763 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1765 2011-05-19 Glenn Morris <rgm@gnu.org>
1767 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1768 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1769 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1770 (lisp): Set the order to that of loadup.el.
1771 (shortlisp): Make it a copy of $lisp.
1772 (SOME_MACHINE_LISP): Remove.
1773 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1774 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1776 2011-05-18 Kenichi Handa <handa@m17n.org>
1778 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1779 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1780 (find_automatic_composition): Mostly rewrite for efficiency.
1782 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1784 * makefile.w32-in: Update dependencies.
1786 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1788 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1789 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1791 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1793 Fix some integer overflow issues, such as string length overflow.
1795 * insdel.c (count_size_as_multibyte): Check for string overflow.
1797 * character.c (lisp_string_width): Check for string overflow.
1798 Use EMACS_INT, not int, for string indexes and lengths; in
1799 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1800 the resulting string length overflows an EMACS_INT; instead,
1801 report a string overflow if no precision given. When checking for
1802 precision exhaustion, use a check that cannot possibly have
1803 integer overflow. (Bug#8675)
1804 * character.h (lisp_string_width): Adjust to new signature.
1806 * alloc.c (string_overflow): New function.
1807 (Fmake_string): Use it. This doesn't change behavior, but saves
1808 a few bytes and will simplify future changes.
1809 * character.c (string_escape_byte8): Likewise.
1810 * lisp.h (string_overflow): New decl.
1812 Fixups, following up to the user-interface timestamp change.
1813 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1814 for UI timestamps, instead of unsigned long.
1815 * msdos.c (mouse_get_pos): Likewise.
1816 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1817 * w32gui.h (Time): Define by including "systime.h" rather than by
1818 declaring it ourselves. (Bug#8664)
1820 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1821 * image.c (clear_image_cache): Likewise.
1823 * term.c (term_mouse_position): Don't assume time_t wraparound.
1825 Be more systematic about user-interface timestamps.
1826 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1827 and sometimes 'EMACS_UINT', to represent these timestamps.
1828 This change causes it to use 'Time' uniformly, as that's what X uses.
1829 This makes the code easier to follow, and makes it easier to catch
1830 integer overflow bugs such as Bug#8664.
1831 * frame.c (Fmouse_position, Fmouse_pixel_position):
1832 Use Time, not unsigned long, for user-interface timestamps.
1833 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1834 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1835 * keyboard.h (last_event_timestamp): Likewise.
1836 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1837 * menu.h (xmenu_show): Likewise.
1838 * term.c (term_mouse_position): Likewise.
1839 * termhooks.h (struct input_event.timestamp): Likewise.
1840 (struct terminal.mouse_position_hook): Likewise.
1841 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1842 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1843 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1844 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1846 * menu.h, termhooks.h: Include "systime.h", for Time.
1848 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1849 Don't assume that the difference between two unsigned long values
1850 can fit into an integer. At this point, we know button_down_time
1851 <= event->timestamp, so the difference must be nonnegative, so
1852 there's no need to cast the result if double-click-time is
1853 nonnegative, as it should be; check that it's nonnegative, just in
1854 case. This bug is triggered when events are more than 2**31 ms
1855 apart (about 25 days). (Bug#8664)
1857 * xselect.c (last_event_timestamp): Remove duplicate decl.
1858 (x_own_selection): Remove needless cast to unsigned long.
1860 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1861 that always fit in int. Use a sentinel instead of a counter, to
1862 avoid a temp and to allay GCC's concerns about possible int overflow.
1863 * frame.h (struct frame): Use int for menu_bar_items_used
1864 instead of EMACS_INT, since it always fits in int.
1866 * menu.c (grow_menu_items): Check for int overflow.
1868 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1870 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1871 Before, the code was not consistent. These values cannot exceed
1872 2**31 - 1 so there's no need to make them unsigned.
1873 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1874 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1875 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1877 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1879 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1880 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1881 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1882 presumably because the widths might not match.
1884 * window.c (size_window): Avoid needless test at loop start.
1886 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1888 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1890 2011-05-12 Drew Adams <drew.adams@oracle.com>
1892 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1894 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1896 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1897 `width' to `bar_area_x' and `bar_area_width', respectively.
1898 (x_scroll_run): Take account of fringe background extension.
1900 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1901 Rename local vars `left' and `width' to `bar_area_x' and
1902 `bar_area_width', respectively.
1903 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1904 background extension.
1906 2011-05-10 Jim Meyering <meyering@redhat.com>
1908 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1910 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1912 * image.c (Finit_image_library): Return t for built-in image types,
1913 like pbm and xbm. (Bug#8640)
1915 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1917 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1919 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1921 * w32console.c (Fset_screen_color): Doc fix.
1922 (Fget_screen_color): New function.
1923 (syms_of_ntterm): Defsubr it.
1925 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1926 unlink the temporary file if Fcall_process didn't create it in the
1928 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1929 child process will be redirected to a file specified with `:file'.
1930 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1931 cue to call_process_cleanup not to close that handle.
1933 2011-05-07 Ben Key <bkey76@gmail.com>
1935 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1936 one of two shell specific rules, either bootstrap-temacs-CMD or
1937 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1938 to the previous implementation of the bootstrap-temacs rule.
1939 The bootstrap-temacs-CMD rule is similar to the previous
1940 implementation of the bootstrap-temacs rule except that it
1941 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1944 These changes, along with some changes to nt/configure.bat,
1945 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1946 earlier fix to add support for --cflags and --ldflags options
1947 that include quotes so that it works whether make uses cmd or
1950 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1952 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1953 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1955 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1956 a string. Handle both cases.
1957 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1958 (Fdbus_register_method): Use Qinvalid_function.
1960 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1962 * makefile.w32-in: Update dependencies.
1963 (LISP_H): Add inttypes.h and stdin.h.
1964 (PROCESS_H): Add unistd.h.
1966 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1968 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1969 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1971 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1973 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1975 * term.c (vfatal): Remove stray call to va_end.
1976 It's not needed and the C Standard doesn't allow it here anyway.
1978 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
1979 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
1981 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
1984 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
1986 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
1988 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
1990 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
1992 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
1994 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
1995 * charset.c (Fdefine_charset_internal): Don't initialize
1996 charset.code_space[15]. The value was garbage, on hosts with
1997 32-bit int (Bug#8600).
1999 * lread.c (read_integer): Be more consistent with string-to-number.
2000 Use string_to_number to do the actual conversion; this avoids
2001 rounding errors and fixes some other screwups. Without this fix,
2002 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2003 (digit_to_number): Move earlier, for benefit of read_integer.
2004 Return -1 if the digit is out of range for the base, -2 if it is
2005 not a digit in any supported base. (Bug#8602)
2007 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2009 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2010 to match comment at start of function. This also removes a
2011 GCC warning about overflow in a 32+64-bit port.
2013 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2015 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2016 Reported by Stefan Monnier in
2017 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2018 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2019 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2021 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2022 (EMACS_UINTPTR): Likewise, with uintptr_t.
2024 * lisp.h: Prefer 64-bit EMACS_INT if available.
2025 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2026 on 32-bit hosts that have 64-bit int, so that they can access
2028 However, temporarily disable this change unless the temporary
2029 symbol WIDE_EMACS_INT is defined.
2031 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2033 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2034 This removes an assumption that EMACS_INT and long are the same
2035 width as pointers. The assumption is true for Emacs porting targets
2036 now, but we want to make other targets possible.
2037 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2038 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2039 In the rest of the code, change types of integers that hold casted
2040 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2041 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2042 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2043 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2044 No need to cast type when ORing.
2045 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2046 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2047 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2048 assume EMACS_INT is the same width as char *.
2049 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2050 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2051 Remove no-longer-needed casts.
2052 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2053 (xg_tool_bar_help_callback, xg_make_tool_item):
2054 Use EMACS_INTPTR to hold an integer
2055 that will be cast to void *; this can avoid a GCC warning
2056 if EMACS_INT is not the same width as void *.
2057 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2058 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2059 (current_message_1, set_message_1):
2060 Use a local to convert to proper width without a cast.
2061 * xmenu.c (dialog_selection_callback): Likewise.
2063 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2064 Also, don't assume VALBITS / RAND_BITS is less than 5,
2065 and don't rely on undefined behavior when shifting a 1 left into
2067 * lisp.h (get_random): Change signature to match.
2069 * lread.c (hash_string): Use size_t, not int, for hash computation.
2070 Normally we prefer signed values; but hashing is special, because
2071 it's better to use unsigned division on hash table sizes so that
2072 the remainder is nonnegative. Also, size_t is the natural width
2073 for hashing into memory. The previous code used 'int', which doesn't
2074 retain enough info to hash well into very large tables.
2075 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2077 * dbusbind.c: Don't possibly lose pointer info when converting.
2078 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2079 Use XPNTR rather than XHASH, so that the high-order bits of
2080 the pointer aren't lost when converting through void *.
2082 * eval.c (Fautoload): Don't double-shift a pointer.
2084 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2086 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2088 * gnutls.c (DEF_GNUTLS_FN):
2089 * image.c (DEF_IMGLIB_FN): Make function pointers static.
2091 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
2093 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
2096 2011-05-05 Eli Zaretskii <eliz@gnu.org>
2098 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
2099 New version that can reserve upto 2GB of heap space.
2101 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
2103 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
2105 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
2107 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
2108 `gnutls_certificate_set_x509_key_file'.
2110 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
2112 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
2113 Update dependencies.
2115 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2117 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
2118 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
2119 Remove unused parameter `fildes'.
2120 * process.c (read_process_output, send_process): Don't pass it.
2122 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2124 Fix previous change: the library cache is defined in w32.c.
2125 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
2126 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
2128 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2130 Implement dynamic loading of GnuTLS on Windows.
2132 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
2133 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
2134 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2137 * gnutls.c (Qgnutls_dll): Define.
2138 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
2139 (gnutls_*): Declare function pointers.
2140 (init_gnutls_functions): New function to initialize function pointers.
2141 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
2142 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
2143 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2144 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
2145 (emacs_gnutls_write, emacs_gnutls_read)
2146 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
2147 (Fgnutls_available_p): New function.
2148 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
2149 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
2150 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
2152 * image.c: Include w32.h.
2153 (Vimage_type_cache): Delete.
2154 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
2155 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
2156 (w32_delayed_load): Move to w32.c.

2161 (w32_delayed_load): Move from image.c. When loading a library, record
2162 its filename in the :loaded-from property of the library id.
2163 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
2164 Initialize and staticpro them.
2165 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
2167 * process.c: Include lisp.h before w32.h, not after.
2168 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
2169 instead of gnutls_record_check_pending.
2171 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
2173 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
2175 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
2176 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
2179 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
2181 * xterm.c (x_set_frame_alpha): Do not set property on anything
2182 else than FRAME_X_OUTER_WINDOW (Bug#8608).
2184 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
2186 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

2200 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
2202 * callproc.c: Indentation fixup.
2204 * sysdep.c (wait_for_termination_1): Make static.
2205 (wait_for_termination, interruptible_wait_for_termination):
2206 Move after wait_for_termination_1.
2208 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
2210 * sysdep.c (interruptible_wait_for_termination): New function
2211 which is like wait_for_termination, but allows keyboard
2214 * callproc.c (Fcall_process): Add (:file "file") as an option for
2216 (Fcall_process_region): Ditto.
2218 2011-04-30 Eli Zaretskii <eliz@gnu.org>
2220 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
2221 rather than `XVECTOR (FOO)->size'.
2223 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2224 inttypes.h, as a gnulib replacement is used if it not available in
2227 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2229 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
2230 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
2231 of MOST_POSITIVE_FIXNUM. (Bug#8528)
2233 * coding.c (coding_alloc_by_realloc): Error out if destination
2234 will grow beyond MOST_POSITIVE_FIXNUM.
2235 (decode_coding_emacs_mule): Abort if there isn't enough place in
2236 charbuf for the composition carryover bytes. Reserve an extra
2237 space for up to 2 characters produced in a loop.
2238 (decode_coding_iso_2022): Abort if there isn't enough place in
2239 charbuf for the composition carryover bytes.
2241 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2243 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
2244 aborting when %lld or %lll format is passed.

2254 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2256 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
2257 (SIZE_MAX): Move defn after all includes, as they might #define it.
2259 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2261 * w32.c (init_environment): Warn about defaulting HOME to C:\.
2263 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2265 * keyboard.c (Qdelayed_warnings_hook): Define.
2266 (command_loop_1): Run `delayed-warnings-hook'
2267 if Vdelayed_warnings_list is non-nil.
2268 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2269 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2271 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2273 * doprnt.c (doprnt): Don't return value smaller than the buffer
2274 size if the message was truncated. (Bug#8545).

2283 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
2285 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
2287 * makefile.w32-in: Update dependencies.
2289 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2291 Improve `doprnt' and its usage. (Bug#8545)
2292 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2293 `format_end'. Remove support for %l as a conversion specifier.
2294 Don't use xrealloc. Improve diagnostics when the %l size modifier
2295 is used. Update the commentary.
2297 * eval.c (verror): Simplify calculation of size_t.
2299 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2302 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2304 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2307 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2309 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2310 This makes this file independent of the recent pseudovector change.
2312 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2314 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2316 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2317 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2318 Remove unused local.
2319 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2321 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2322 GCC 4.6.0 optimizes based on type-based alias analysis.
2323 For example, if b is of type struct buffer * and v of type struct
2324 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2325 != &v->size, and therefore "v->size = 1; b->size = 2; return
2326 v->size;" must therefore return 1. This assumption is incorrect
2327 for Emacs, since it type-puns struct Lisp_Vector * with many other
2328 types. To fix this problem, this patch adds a new type struct
2329 vectorlike_header that documents the constraints on layout of vectors
2330 and pseudovectors, and helps optimizing compilers not get fooled
2331 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2332 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2333 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2335 (XSETPVECTYPE): Rewrite in terms of new macro.
2336 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2337 This is a bit clearer, and further avoids the possibility of
2338 undesirable aliasing.
2339 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2340 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2341 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2342 since Lisp_Subr is a special case (no "next" field).
2343 (ASIZE): Now uses header.size rather than size.
2344 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2345 to avoid the hassle of writing XVECTOR (foo)->header.size.
2346 (struct vectorlike_header): New type.
2347 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2348 object, to help avoid aliasing.
2349 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2350 (SUBRP): Likewise, since Lisp_Subr is a special case.
2351 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2352 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2353 (struct Lisp_Hash_Table): Combine first two members into a single
2354 struct vectorlike_header member. All uses of "size" and "next" members
2355 changed to be "header.size" and "header.next".
2356 * buffer.h (struct buffer): Likewise.
2357 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2358 * frame.h (struct frame): Likewise.
2359 * process.h (struct Lisp_Process): Likewise.
2360 * termhooks.h (struct terminal): Likewise.
2361 * window.c (struct save_window_data, struct saved_window): Likewise.
2362 * window.h (struct window): Likewise.
2363 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2364 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2365 * buffer.c (init_buffer_once): Likewise.
2366 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2368 * process.c (Fformat_network_address): Use local var for size,
2371 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2373 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2374 * data.c (atof): Remove decl; no longer used or needed.
2375 (digit_to_number): Move to lread.c.
2376 (Fstring_to_number): Use new string_to_number function, to be
2377 consistent with how the Lisp reader treats infinities and NaNs.
2378 Do not assume that floating-point numbers represent EMACS_INT
2379 without losing information; this is not true on most 64-bit hosts.
2380 Avoid double-rounding errors, by insisting on integers when
2381 parsing non-base-10 numbers, as the documentation specifies.
2382 * lisp.h (string_to_number): New decl, replacing ...
2383 (isfloat_string): Remove.
2384 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2385 (read1): Do not accept +. and -. as integers; this
2386 appears to have been a coding error. Similarly, do not accept
2387 strings like +-1e0 as floating point numbers. Do not report
2388 overflow for integer overflows unless the base is not 10 which
2389 means we have no simple and reliable way to continue.
2390 Break out the floating-point parsing into a new
2391 function string_to_number, so that Fstring_to_number parses
2392 floating point numbers consistently with the Lisp reader.
2393 (digit_to_number): Move here from data.c. Make it static inline.
2394 (E_CHAR, EXP_INT): Remove, replacing with ...
2395 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2396 (string_to_number): New function, replacing isfloat_string.
2397 This function checks for valid syntax and produces the resulting
2398 Lisp float number too. Rework it so that string-to-number
2399 no longer mishandles examples like "1.0e+". Use strtoumax,
2400 so that overflow for non-base-10 numbers is reported only when
2401 there's no portable and simple way to convert to floating point.
2403 * textprop.c (set_text_properties_1): Rewrite for clarity,
2404 and to avoid GCC warning about integer overflow.
2406 * intervals.h (struct interval): Use EMACS_INT for members
2407 where EMACS_UINT might cause problems. See
2408 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2409 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2410 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2412 (offset_intervals): Tell GCC not to worry about length overflow
2413 when negating a negative length.
2415 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2416 (overrun_check_free): Likewise.
2418 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2419 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2422 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2423 (gnutls_make_error): Rename local to avoid shadowing.
2424 (gnutls_emacs_global_deinit): ifdef out; not used.
2425 (Fgnutls_boot): Use const for pointer to readonly storage.
2426 Comment out unused local. Fix pointer signedness problems.
2428 * lread.c (openp): Don't stuff size_t into an 'int'.
2429 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2430 about possible signed overflow.
2432 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2433 (GDK_KEY_g): Don't define if already defined.
2434 (xg_prepare_tooltip): Avoid pointer signedness problem.
2435 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2437 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2438 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2440 * xfns.c (Fx_window_property): Simplify a bit,
2441 to make a bit faster and to avoid GCC 4.6.0 warning.
2442 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2444 * fns.c (internal_equal): Don't assume size_t fits in int.
2446 * alloc.c (compact_small_strings): Tighten assertion a little.
2448 Replace pEd with more-general pI, and fix some printf arg casts.
2449 * lisp.h (pI): New macro, generalizing old pEd macro to other
2450 conversion specifiers. For example, use "...%"pI"d..." rather
2451 than "...%"pEd"...".
2452 (pEd): Remove. All uses replaced with similar uses of pI.
2453 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2454 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2455 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2456 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2457 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2458 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2459 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2461 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2462 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2463 * print.c (safe_debug_print, print_object): Likewise.
2464 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2466 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2467 avoiding the 0 flag, which is not portable.
2468 * process.c (Fmake_network_process): Use pI to avoid cast.
2469 * region-cache.c (pp_cache): Likewise.
2470 * xdisp.c (decode_mode_spec): Likewise.
2471 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2472 behavior on 64-bit hosts with printf arg.
2473 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2474 (x_stop_queuing_selection_requests): Likewise.
2475 (x_get_window_property): Don't truncate byte count to an 'int'
2478 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2479 here, since it parses constructs like leading '-' and spaces,
2480 which are not wanted; and it overflows with large numbers.
2481 Instead, simply match F[0-9]+, which is what is wanted anyway.
2483 * alloc.c: Remove unportable assumptions about struct layout.
2484 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2485 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2486 (allocate_vectorlike, make_pure_vector): Use the new macros,
2487 plus offsetof, to remove unportable assumptions about struct layout.
2488 These assumptions hold on all porting targets that I know of, but
2489 they are not guaranteed, they're easy to remove, and removing them
2490 makes further changes easier.
2492 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2493 This doesn't fix a bug but makes the code clearer.
2494 (string_overrun_cookie): Now const. Use initializers that
2495 don't formally overflow signed char, to avoid warnings.
2496 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2497 can cause Emacs to crash when string overrun checking is enabled.
2498 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2499 multiple of sizeof (EMACS_INT); it need not be, if
2500 alignof(EMACS_INT) < sizeof (EMACS_INT).
2501 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2503 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

2524 (check_string_free_list): Convert to standard C.
2526 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2528 * w32.c (emacs_gnutls_push): Fix typo.
2530 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2532 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2533 "cast to pointer from integer of different size".
2535 Improve doprnt and its use in verror. (Bug#8545)
2536 * doprnt.c (doprnt): Document the set of format control sequences
2537 supported by the function. Use SAFE_ALLOCA instead of always
2540 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2541 is one byte too soon. Don't use xrealloc; instead xfree and
2544 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2546 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

2550 gnutls_global_initialized. Added internals for the
2551 :verify-hostname-error, :verify-error, and :verify-flags
2552 parameters of `gnutls-boot' and documented those parameters in the
2553 docstring. Start callback support.
2554 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2555 unless a fatal error occured. Call gnutls_alert_send_appropriate
2556 on error. Return error code.
2557 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
2558 (emacs_gnutls_read): Likewise.
2559 (Fgnutls_boot): Return handshake error code.

2632 Improve overflow protection. Support `l' modifier for integer
2633 conversions. Support %l conversion. Don't assume an EMACS_INT
2634 argument for integer conversions and for %c.

2644 (callint.o): Depend on character.h.
2646 * eval.c (internal_lisp_condition_case): Include the handler
2647 representation in the error message.
2648 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
2649 when breaking from the loop.
2651 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
2653 * callint.c (Fcall_interactively): When displaying error message
2654 about invalid control letter, pass the character's codepoint, not
2655 a pointer to its multibyte form. Improve display of the character
2656 in octal and display also its hex code.
2658 * character.c (char_string): Use %x to display the (unsigned)
2659 codepoint of an invalid character, to avoid displaying a bogus
2662 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
2663 `error', not SYMBOL_NAME itself.

2671 argument to `error'.
2673 2011-04-23 Eli Zaretskii <eliz@gnu.org>
2675 * s/ms-w32.h (localtime): Redirect to sys_localtime.

2752 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
2753 so that we aren't warned about unused symbols.
2755 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
2757 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

2764 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
2765 (x_dispatch_event): Declare static if USE_GTK, and
2766 define if USE_GTK || USE_X_TOOLKIT.
2767 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
2768 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
2769 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
2770 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
2772 * xmenu.c (menu_help_callback): Pointer type fixes.
2773 Use const pointers when pointing at readonly data. Avoid pointer
2775 (FALSE): Remove unused macro.

2784 * keyboard.c (make_lispy_event): Remove unused local var.
2786 * frame.c, frame.h (x_get_resource_string): Bring this back, but
2787 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
2789 * bitmaps: Change bitmaps from unsigned char back to the X11
2790 compatible char. Avoid the old compiler warnings about
2791 out-of-range initializers by using, for example, '\xab' rather
2794 * xgselect.c (xgselect_initialize): Check vs interface
2795 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
2797 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.
2799 * xterm.c (x_create_toolkit_scroll_bar): Use const * for pointers

2860 * nsfont.m: Fixed bugs in ns_get_family and
2861 ns_descriptor_to_entity that were caused by using free to

2864 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
2865 --enable-checking=xmallocoverrun). xfree is now used to
2866 deallocate these memory blocks.

3255 This makes it easier for human readers (and static analyzers)
3256 to see whether these variables are used from other modules.
3257 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
3258 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
3259 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
3260 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
3261 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
3262 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
3263 * xmenu.c, xselect.c:
3264 Declare Q* vars static if they are not used in other modules.
3265 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
3266 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
3267 Remove decls of unexported vars.
3268 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
3270 * lisp.h (DEFINE_FUNC): Make sname 'static'.
3272 Make Emacs functions such as Fatom 'static' by default.
3273 This makes it easier for human readers (and static analyzers)
3274 to see whether these functions can be called from other modules.
3275 DEFUN now defines a static function. To make the function external
3276 so that it can be used in other C modules, use the new macro DEFUE.
3277 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
3278 (Finit_image_library):
3279 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
3280 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
3281 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
3282 Remove decls, since these functions are now static.
3283 (Funintern, Fget_internal_run_time): New decls, since these functions
3284 were already external.
3286 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
3287 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
3288 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
3289 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
3290 * keyboard.c, keymap.c, lread.c:
3291 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
3292 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
3293 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
3294 Mark functions with DEFUE instead of DEFUN,
3295 if they are used in other modules.
3296 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
3297 decls for now-static functions.
3298 * buffer.h (Fdelete_overlay): Remove decl.
3299 * callproc.c (Fgetenv_internal): Mark as internal.
3300 * composite.c (Fremove_list_of_text_properties): Remove decl.

3304 * doc.c (Fdocumntation_property): New forward static decl.
3305 * eval.c (Ffetch_bytecode): New forward static decl.
3306 (Funintern): Remove extern decl; now in .h file where it belongs.
3307 * fileio.c (Fmake_symbolic_link): New forward static decl.
3308 * image.c (Finit_image_library): New forward static decl.
3309 * insdel.c (Fcombine_after_change_execute): Make forward decl static.

3311 (Fremove_list_of_text_properties): Remove decls.
3312 * keyboard.c (Fthis_command_keys): Remove decl.
3313 (Fcommand_execute): New forward static decl.
3314 * keymap.c (Flookup_key): New forward static decl.
3315 (Fcopy_keymap): Now static.
3316 * keymap.h (Flookup_key): Remove decl.
3317 * process.c (Fget_process): New forward static decl.
3318 (Fprocess_datagram_address): Mark as internal.
3319 * syntax.c (Fsyntax_table_p): New forward static decl.

3325 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
3327 * editfns.c (Fformat): Remove unreachable code.
3329 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
3331 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
3334 2011-04-13 Eli Zaretskii <eliz@gnu.org>
3336 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
3337 when at ZV. (Bug#8487)
3339 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3341 * charset.c (Fclear_charset_maps): Use xfree instead of free.
3343 * keyboard.c (parse_tool_bar_item): Likewise.
3344 * sound.c (sound_cleanup, alsa_close): Likewise.
3345 * termcap.c (tgetent): Likewise.
3346 * xfns.c (x_default_font_parameter): Likewise.
3347 * xsettings.c (read_and_apply_settings): Likewise.
3349 * alloc.c (overrun_check_malloc, overrun_check_realloc)
3350 (overrun_check_free): Protoize.
3352 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3354 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3355 since callers should never pass a negative size.
3356 Change the signature to match that of plain 'read' and 'write'; see
3357 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3358 * lisp.h: Update prototypes of emacs_write and emacs_read.
3360 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3362 * xdisp.c (redisplay_window): Don't try to determine the character
3363 position of the scroll margin if the window start point w->startp
3364 is outside the buffer's accessible region. (Bug#8468)
3366 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3368 Fix write-region and its subroutines for buffers > 2GB.
3369 * fileio.c (a_write, e_write): Modify declaration of arguments and
3370 local variables to support buffers larger than 2GB.
3371 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3373 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3374 argument, local variables, and return value.
3376 * lisp.h: Update prototypes of emacs_write and emacs_read.
3378 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3380 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3382 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3384 Fix more problems found by GCC 4.6.0's static checks.
3386 * xdisp.c (vmessage): Use a better test for character truncation.
3388 * charset.c (load_charset_map): <, not <=, for optimization,
3389 and to avoid potential problems with integer overflow.
3390 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3391 * casetab.c (set_identity, shuffle): Likewise.
3392 * editfns.c (Fformat): Likewise.
3393 * syntax.c (skip_chars): Likewise.
3395 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3396 This also lets GCC 4.6.0 generate slightly better loop code.
3398 * callint.c (Fcall_interactively): <, not <=, for optimization.
3399 (Fcall_interactively): Count the number of arguments produced,
3400 not the number of arguments given. This is simpler and lets GCC
3401 4.6.0 generate slightly better code.
3403 * ftfont.c: Distingish more carefully between FcChar8 and char.
3404 The previous code passed unsigned char * to a functions like
3405 strlen and xstrcasecmp that expect char *, which does not
3406 conform to the C standard.
3407 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3408 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3409 char * when the C standard requires it.
3411 * keyboard.c (read_char): Remove unused var.
3413 * eval.c: Port to Windows vsnprintf (Bug#8435).
3415 (SIZE_MAX): Define if the headers do not.
3416 (verror): Do not give up if vsnprintf returns a negative count.
3417 Instead, grow the buffer. This ports to Windows vsnprintf, which
3418 does not conform to C99. Problem reported by Eli Zaretskii.
3419 Also, simplify the allocation scheme, by avoiding the need for
3420 calling realloc, and removing the ALLOCATED variable.
3422 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3424 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3425 But keep the doprint source code for now, as we might revamp it
3426 and use it again (Bug#8435).
3427 * lisp.h (doprnt): Remove.
3428 * Makefile.in (base_obj): Remove doprnt.o.
3429 * deps.mk (doprnt.o): Remove.
3431 error: Print 32- and 64-bit integers portably (Bug#8435).
3432 Without this change, on typical 64-bit hosts error ("...%d...", N)
3433 was used to print both 32- and 64-bit integers N, which relied on
3435 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3437 * lisp.h (error, verror): Mark as printf-like functions.
3438 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3439 Report overflow in size calculations when allocating printf buffer.
3440 Do not truncate output string at its first null byte.
3441 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3442 Truncate the output at a character boundary, since vsnprintf does not
3444 * charset.c (check_iso_charset_parameter): Convert internal
3445 character to string before calling 'error', since %c now has the
3447 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3448 overflow when computing char to be passed to 'error'. Do not
3449 pass Lisp_Object to 'error'; pass the integer instead.
3450 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3451 formatted with plain %d.
3453 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3455 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3457 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3459 * xterm.c (x_catch_errors): Remove duplicate declaration.
3461 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3463 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3465 2011-04-10 Jim Meyering <meyering@redhat.com>
3467 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3468 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3469 return ssize_t not "int", and use size_t as the buffer length.
3470 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3471 * gnutls.h: Update declarations.
3472 * process.c (read_process_output): Use ssize_t, to match.
3473 (send_process): Likewise.
3475 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3477 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3479 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3481 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3482 Use unsigned char, to match FcChar8 type definition.
3484 * xterm.c (handle_one_xevent):
3485 * xmenu.c (create_and_show_popup_menu):
3486 * xselect.c (x_decline_selection_request)
3487 (x_reply_selection_request): Avoid type-punned deref of X events.
3489 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3491 Fix some uses of `int' instead of EMACS_INT.
3492 * search.c (string_match_1, fast_string_match)
3493 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3494 (scan_buffer, find_next_newline_no_quit)
3495 (find_before_next_newline, search_command, Freplace_match)
3496 (Fmatch_data): Make some `int' variables be EMACS_INT.
3498 * xdisp.c (display_count_lines): 3rd argument and return value now
3499 EMACS_INT. All callers changed.
3500 (pint2hrstr): Last argument is now EMACS_INT.
3502 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3503 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3504 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
3505 (decode_coding_utf_16, decode_coding_emacs_mule)
3506 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
3507 (decode_coding_ccl, decode_coding_charset)
3508 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
3509 (decode_coding_iso_2022, decode_coding_emacs_mule)
3510 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
3511 <char_offset, last_offset>: Declare EMACS_INT.
3512 (encode_coding_utf_8, encode_coding_utf_16)

3515 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
3516 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3518 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3519 (encode_invocation_designation): Last argument P_NCHARS is now
3521 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3522 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
3524 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
3527 * ccl.c (Fccl_execute_on_string): Declare some variables
3530 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

3542 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3544 * keyboard.c (read_char): Call Lisp function help-form-show,
3545 instead of using internal_with_output_to_temp_buffer.
3546 (Qhelp_form_show): New var.
3547 (syms_of_keyboard): Use DEFSYM macro.
3549 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3551 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3553 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
3555 * process.c (Flist_processes): Remove to Lisp.

3564 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3566 Fix more problems found by GCC 4.6.0's static checks.
3568 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3570 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3572 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
3574 * xdisp.c (vmessage): Mark as a printf-like function.
3576 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
3578 * sound.c (sound_warning): Don't crash if arg contains a printf format.
3580 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
3581 printf-like functions.
3582 (tiff_load): Add casts to remove these marks before passing them
3583 to system-supplied API.
3585 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3587 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3588 This avoids several warnings with gcc -Wstrict-overflow.
3589 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3590 directly, rather than having caller test rule sign. This avoids
3591 some unnecessary tests.
3592 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3593 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3594 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

3608 by using the new macro.
3610 * textprop.c (set_text_properties_1): Change while to do-while,
3611 since the condition is always true at first.
3613 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3614 (interval_deletion_adjustment): Return unsigned value.
3617 * process.c (list_processes_1, create_pty, read_process_output):

3633 * print.c (print_error_message): Avoid int overflow.
3635 * font.c (font_list_entities): Redo for clarity,
3636 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3638 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3639 (font_score): Avoid potential overflow in diff calculation.
3641 * fns.c (substring_both): Remove var that is set but not used.
3642 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3644 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3646 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3647 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3648 can always succeed if overflow has undefined behavior.
3650 * search.c (boyer_moore, wordify): Remove vars set but not used.
3651 (wordify): Omit three unnecessary tests.
3653 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3654 All callers changed. This avoids the need for an unused var.
3656 * casefiddle.c (casify_region): Remove var that is set but not used.
3658 * dired.c (file_name_completion): Remove var that is set but not used.
3660 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3662 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3663 (Finsert_file_contents): Remove unnecessary code checking fd.
3665 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3666 Check for integer overflow on size calculations.
3668 * buffer.c (Fprevious_overlay_change): Remove var that is set
3671 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3672 Remove vars that are set but not used.
3673 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3674 (timer_check_2): Mark vars as initialized.
3676 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3678 * image.c (lookup_image): Remove var that is set but not used.
3679 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3681 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3682 that are set but not used.
3684 * xfns.c (make_invisible_cursor): Don't return garbage
3685 if XCreateBitmapFromData fails (Bug#8410).
3687 * xselect.c (x_get_local_selection, x_handle_property_notify):
3688 Remove vars that are set but not used.
3690 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

3694 Remove var that is set but not used.
3695 (scroll_bar_windows_size): Now size_t, not int.
3696 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
3699 * xfaces.c (realize_named_face): Remove vars that are set but not used.
3700 (map_tty_color) [!defined MSDOS]: Likewise.
3702 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
3704 * coding.c: Remove vars that are set but not used.
3705 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
3706 All callers changed.
3707 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
3708 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
3709 (decode_coding_charset): Remove vars that are set but not used.
3711 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
3712 that is set but not used.
3714 * print.c (print_object): Remove var that is set but not used.
3716 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3717 The gnulib version avoids calling malloc in the usual case,
3718 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3719 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3720 * filelock.c (current_lock_owner): Likewise.
3721 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
3722 * sysdep.c: Include allocator.h, careadlinkat.h.
3723 (emacs_no_realloc_allocator): New static constant.
3724 (emacs_readlink): New function.

3731 first non-nil return value).
3733 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
3735 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
3736 if not defined (Bug#8403).
3738 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3740 * xdisp.c (display_count_lines): Remove parameter `start',

3745 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3746 and thereabouts. All callers changed.
3747 (get_per_char_metric): Remove parameter `f', unused since
3748 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
3750 2011-04-02 Jim Meyering <meyering@redhat.com>
3752 do not dereference NULL upon failed strdup
3753 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
3754 (ns_get_family): Likewise.
3756 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
3758 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
3760 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3762 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
3765 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
3767 Add lexical binding.
3769 * window.c (Ftemp_output_buffer_show): New fun.
3770 (Fsave_window_excursion):
3771 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
3773 * lread.c (lisp_file_lexically_bound_p): New function.
3774 (Fload): Bind Qlexical_binding.
3775 (readevalloop): Remove `evalfun' arg.
3776 Bind Qinternal_interpreter_environment.
3777 (Feval_buffer): Bind Qlexical_binding.
3778 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3780 (syms_of_lread): Declare `lexical-binding'.
3782 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
3784 * keyboard.c (eval_dyn): New fun.
3785 (menu_item_eval_property): Use it.
3787 * image.c (parse_image_spec): Use Ffunctionp.
3789 * fns.c (concat, mapcar1): Accept byte-code-functions.
3791 * eval.c (Fsetq): Handle lexical vars.
3792 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3793 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3794 (FletX, Flet): Obey lexical binding.
3795 (Fcommandp): Handle closures.
3796 (Feval): New `lexical' arg.
3797 (eval_sub): New function extracted from Feval. Use it almost
3798 everywhere where Feval was used. Look up vars in lexical env.
3800 (Ffunctionp): Move from subr.el.
3801 (Ffuncall): Handle closures.
3802 (apply_lambda): Remove `eval_flags'.
3803 (funcall_lambda): Handle closures and new byte-code-functions.
3804 (Fspecial_variable_p): New function.
3805 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3806 but without exporting it to Lisp.
3808 * doc.c (Fdocumentation, store_function_docstring):
3809 * data.c (Finteractive_form): Handle closures.
3811 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3814 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3816 (exec_byte_code): New function extracted from Fbyte_code to handle new
3817 calling convention for byte-code-functions. Add new byte-codes.
3819 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
3821 * alloc.c (Fmake_symbol): Init new `declared_special' field.
3823 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
3825 * xdisp.c (redisplay_internal): Fix prototype.
3827 2011-03-31 Eli Zaretskii <eliz@gnu.org>
3829 * xdisp.c (SCROLL_LIMIT): New macro.
3830 (try_scrolling): Use it when setting scroll_limit.
3831 Limit scrolling to 100 screen lines.
3832 (redisplay_window): Even when falling back on "recentering",
3833 position point in the window according to scroll-conservatively,
3834 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3836 (try_scrolling): When point is above the window, allow searching
3837 as far as scroll_max, or one screenful, to compute vertical
3838 distance from PT to the scroll margin position. This prevents
3839 try_scrolling from unnecessarily failing when
3840 scroll-conservatively is set to a value slightly larger than the
3841 window height. Clean up the case of PT below the margin at bottom
3842 of window: scroll_max can no longer be INT_MAX. When aggressive
3843 scrolling is in use, don't let point enter the opposite scroll
3844 margin as result of the scroll.
3845 (syms_of_xdisp) <scroll-conservatively>: Document the
3846 threshold of 100 lines for never-recentering scrolling.
3848 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

3852 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
3853 (message_log_check_duplicate): Remove parameters `prev_bol' and
3854 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3855 (redisplay_internal): Remove parameter `preserve_echo_area',
3856 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3858 * indent.c (Fvertical_motion):
3859 * window.c (window_scroll_pixel_based, Frecenter):
3860 Don't pass `need_y_p' to `move_it_by_lines'.
3862 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3864 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3865 steal a few bits to be more compact.
3866 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3867 Remove unneeded casts.
3869 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3871 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3873 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3874 binding" message (bug#7967).
3876 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3878 Fix more problems found by GCC 4.6.0's static checks.
3880 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3881 Remove unused local var.
3883 * editfns.c (Fmessage_box): Remove unused local var.
3885 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3886 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3887 Omit unused local vars.
3888 * window.c (shrink_windows): Omit unused local var.
3889 * menu.c (digest_single_submenu): Omit unused local var.
3890 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3891 Omit unused local var.
3893 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3894 Don't assume string length fits in int.
3895 (keyremap_step, read_key_sequence): Use size_t for sizes.
3896 (read_key_sequence): Don't check last_real_key_start redundantly.
3898 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3899 instead of alloca (Bug#8344).
3901 * eval.c (Fbacktrace): Don't assume nargs fits in int.
3902 (Fbacktrace_frame): Don't assume nframes fits in int.
3904 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

3911 * cm.c (calccost): Turn while-do into do-while, for clarity.
3913 * keyboard.c (syms_of_keyboard): Use the same style as later
3914 in this function when indexing through an array. This also
3915 works around GCC bug 48267.
3917 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3919 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3921 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3922 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3924 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3925 This avoids undefined behavior on integer overflow, and is a bit
3926 more convenient anyway since it is compared to a size_t variable.
3928 Variadic C functions now count arguments with size_t, not int.
3929 This avoids an unnecessary limitation on 64-bit machines, which
3930 caused (substring ...) to crash on large vectors (Bug#8344).
3931 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

3940 * fns.c (concat): Likewise.
3941 * frame.c (x_set_frame_parameters): Likewise.
3942 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3943 0 if not found, not -1. All callers changed.
3945 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3946 (stack_copy_size): Now size_t, not int.
3947 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3949 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3951 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3952 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3953 All callers changed.

3968 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
3969 don't set the hook to nil, but remove the offending function instead.
3970 (Qcommand_hook_internal): Remove, unused.
3971 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
3972 Vcommand_hook_internal.

3975 (funcall_nil, funcall_not): New functions.
3976 (run_hook_with_args): Call each function through a `funcall' argument.

3989 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
3990 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
3991 All callers changed.
3993 * w32.c (_wsa_errlist): Use braces for struct initializers.
3995 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
3996 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
3997 All callers changed.

3999 used outside xdisp.c).

4066 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
4067 (gap_left, gap_right): Don't call it.
4069 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
4071 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
4072 incurred during fontification.

4153 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4155 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4156 unconditionnaly since it does the check itself.
4158 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4160 Fix more problems found by GCC 4.5.2's static checks.
4162 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4163 the first time through the loop, since we know p0 < p1 then.
4164 This also avoids a gcc -Wstrict-overflow warning.
4166 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4167 leading to a memory leak, possible in functions like
4168 load_charset_map_from_file that can allocate an unbounded number
4169 of objects (Bug#8318).
4171 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4172 that could (at least in theory) be that large.
4174 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4175 This is less likely to overflow, and avoids undefined behavior if
4176 overflow does occur. All callers changed. Use strtoul to scan
4177 for the unsigned long integer.
4178 (pint2hrstr): Simplify and tune code slightly.
4179 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
4181 * scroll.c (do_scrolling): Work around GCC bug 48228.
4182 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
4184 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
4185 This also avoids a warning with gcc -Wstrict-overflow.

4187 This also avoids a warning with gcc -Wstrict-overflow.
4189 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4192 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4194 * process.c (Fmake_network_process): Use socklen_t, not int,
4195 where POSIX says socklen_t is required in portable programs.
4196 This fixes a porting bug on hosts like 64-bit HP-UX, where
4197 socklen_t is wider than int (Bug#8277).
4198 (Fmake_network_process, server_accept_connection):
4199 (wait_reading_process_output, read_process_output):

4212 Make tparam.h and terminfo.c consistent.
4213 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4214 Include tparam.h instead, since it declares them.
4215 * cm.h (PC): Remove extern decl; tparam.h now does this.
4216 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4217 * terminfo.c: Include tparam.h, to check interfaces.
4218 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4219 (tparam): Adjust signature to match interface in tparam.h;
4220 this removes some undefined behavior. Check that outstring and len
4221 are zero, which they always are with Emacs.
4222 * tparam.h (PC, BC, UP): New extern decls.
4224 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
4225 (xftfont_open): Rename locals to avoid shadowing.
4227 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

4261 Rename locals to avoid shadowing.
4263 * sound.c (wav_play, au_play, Fplay_sound_internal):
4264 Fix pointer signedness.
4265 (alsa_choose_format): Remove unused local var.
4266 (wav_play): Initialize a variable to 0, to prevent undefined
4267 behavior (Bug#8278).
4269 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4271 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4273 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4274 clobbering (Bug#8298).
4275 * sysdep.c (sys_subshell): Likewise.
4276 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4278 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4279 This should get cleaned up, so that child_setup has the
4280 same signature on all platforms.
4282 * callproc.c (call_process_cleanup): Now static.
4283 (relocate_fd): Rename locals to avoid shadowing.
4285 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4287 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4288 not to be necessary, and produces flickering.
4290 2011-03-20 Glenn Morris <rgm@gnu.org>
4292 * config.in: Remove file.
4294 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
4296 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
4297 are now in src/globals.h.
4298 (syms_of_minibuf): Remove spurious & from previous change.
4300 2011-03-20 Leo <sdl.web@gmail.com>
4302 * minibuf.c (completing-read-function): New variable.
4303 (completing-read-default): Rename from completing-read.
4304 (completing-read): Call completing-read-function.

4309 Read color file from absolute filename (bug#8250).
4311 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4313 * makefile.w32-in: Update dependencies.
4315 2011-03-17 Eli Zaretskii <eliz@gnu.org>
4317 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
4319 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

4324 (sigchld_handler): Now static.
4326 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
4327 That way, the code declares only the vars that it needs.

4329 * s/cygwin.h (PTY_ITERATION): Likewise.
4330 * s/darwin.h (PTY_ITERATION): Likewise.

4333 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
4334 * process.c (allocate_pty): Don't declare stb unless it's needed.
4336 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
4337 (CONSTANTLIM): Remove; unused.
4338 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
4339 Define only if needed.
4341 * unexelf.c (unexec): Name an expression,
4342 to avoid gcc -Wbad-function-cast warning.
4343 Use a different way to cause a compilation error if anyone uses
4344 n rather than nn, a way that does not involve shadowing.
4345 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4347 * deps.mk (unexalpha.o): Remove; unused.
4349 New file unexec.h, the (simple) interface for unexec (Bug#8267).
4350 * unexec.h: New file.
4351 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
4352 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
4354 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
4355 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:

4372 warning when compiling print.c.
4374 * font.c (font_unparse_fcname): Abort in an "impossible" situation
4375 instead of using an uninitialized var.
4376 (font_sort_entities): Mark var as initialized.
4378 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
4380 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

4412 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4413 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4414 some of which prompt warnings from gcc -Wbad-function-cast.
4415 (Fformat_time_string, Fencode_time, Finsert_char):
4416 (Ftranslate_region_internal, Fformat):
4417 Rename or remove local vars to avoid shadowing.

4435 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4436 Rename locals to avoid shadowing.
4437 (mark_stack): Move local variables into the #ifdef region where
4439 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4440 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4442 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.

4447 avoids undefined behavior in theory.
4449 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4451 Use functions, not macros, for up- and down-casing (Bug#8254).
4452 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4453 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4454 to use the following functions instead of these macros.
4455 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4456 EMACS_INT, since callers assume the returned value fits in int.
4457 (upcase1): Likewise, for UPCASE_TABLE.
4458 (uppercasep, lowercasep, upcase): New static inline functions.
4459 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

4465 (regex_compile, re_search_2, re_match_2_internal):
4466 Remove unused local vars.
4467 (FREE_VAR): Rewrite so as not to use empty "else",
4468 which gcc can warn about.
4469 (regex_compile, re_match_2_internal): Mark locals as initialized.
4470 (RETALLOC_IF): Define only if needed.
4471 (WORDCHAR_P): Likewise. This one is never needed, but is used
4472 only in a comment talking about a compiler bug, so put inside
4473 the #if 0 of that comment.
4474 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4475 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4478 * search.c (boyer_moore): Rename locals to avoid shadowing.
4479 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4480 (PREV_CHAR_BOUNDARY): Likewise.
4482 * search.c (simple_search): Remove unused var.

4501 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4502 New macros, so that the caller can use some names other than
4503 gcpro1, gcpro2, etc.
4504 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4506 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4507 argument, for consistency with GCPRO2_VAR, etc: it is now the
4508 prefix of the variable, not the variable itself. All uses
4510 * dired.c (directory_files_internal, file_name_completion):
4511 Rename locals to avoid shadowing.
4513 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4514 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4515 dired.c's scmp function, had undefined behavior.
4516 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4517 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4518 * buffer.h: ... to here, because these macros use current_buffer,
4519 and the new implementation with inline functions needs to have
4520 current_buffer in scope now, rather than later when the macros
4522 (downcase, upcase1): New static inline functions.
4523 (DOWNCASE, UPCASE1): Reimplement using these functions.
4524 This avoids undefined behavior in expressions like
4525 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4526 from race conditions in accessing the global variables
4527 case_temp1 and case_temp2.
4528 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4529 * lisp.h (case_temp1, case_temp2): Remove their decls.
4530 * character.h (ASCII_CHAR_P): Move from here ...
4531 * lisp.h: ... to here, so that the inline functions mentioned
4534 * dired.c (directory_files_internal_unwind): Now static.
4536 * fileio.c (file_name_as_directory, directory_file_name):
4537 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4539 (file_name_as_directory): Use const pointers when appropriate.
4540 (Fexpand_file_name): Likewise. In particular, newdir might
4541 point at constant storage, so make it a const pointer.
4542 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4543 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4545 (Fset_file_times, Finsert_file_contents, auto_save_error):
4546 Rename locals to avoid shadowing.
4548 * minibuf.c (choose_minibuf_frame_1): Now static.
4549 (Ftry_completion, Fall_completions): Rename or remove locals
4552 * marker.c (bytepos_to_charpos): Remove; unused.
4554 * lisp.h (verify_bytepos, count_markers): New decls,
4555 so that gcc does not warn that these functions aren't declared.
4557 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4558 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4559 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4560 (copy_text): Remove unused local var.
4562 * filelock.c (within_one_second): Now static.
4563 (lock_file_1): Rename local to avoid shadowing.
4565 * buffer.c (fix_overlays_before): Mark locals as initialized.
4566 (fix_start_end_in_overlays): Likewise. This function should be
4567 simplified by using pointers-to-pointers, but that's a different
4569 (switch_to_buffer_1): Now static.
4570 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4571 (report_overlay_modification): Rename locals to avoid shadowing.
4573 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
4574 Fix pointer signedness issue.
4575 (sys_subshell): Mark local as volatile if checking for lint,
4576 to suppress a gcc -Wclobbered warning that does not seem to be right.
4577 (MAXPATHLEN): Define only if needed.
4579 * process.c (serial_open, serial_configure): Move decls from here ...
4580 * systty.h: ... to here, so that they can be checked.
4582 * fns.c (get_random, seed_random): Move extern decls from here ...
4583 * lisp.h: ... to here, so that they can be checked.
4585 * sysdep.c (reset_io): Now static.
4586 (wait_for_termination_signal): Remove; unused.
4588 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

4594 (describe_map_tree):
4595 Rename locals to avoid shadowing.
4597 * keyboard.c: Declare functions static if they are not used elsewhere.
4598 (echo_char, echo_dash, cmd_error, top_level_2):
4599 (poll_for_input, handle_async_input): Now static.
4600 (read_char, kbd_buffer_get_event, make_lispy_position):
4601 (make_lispy_event, make_lispy_movement, apply_modifiers):
4602 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

4615 (DEFINE_DUMMY_FUNCTION): New macro.
4616 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
4618 (main): Add casts to avoid warnings
4619 if GCC considers string literals to be constants.
4621 * lisp.h (fatal_error_signal): Add decl, since it's exported.
4623 * dbusbind.c: Pointer signedness fixes.
4624 (xd_signature, xd_append_arg, xd_initialize):
4625 (Fdbus_call_method, Fdbus_call_method_asynchronously):
4626 (Fdbus_method_return_internal, Fdbus_method_error_internal):
4627 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
4628 (Fdbus_register_signal): Use SSDATA when the context wants char *.
4630 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
4631 if GCC considers string literals to be constants.
4632 (Fdbus_register_service, Fdbus_register_method): Remove unused vars.
4634 2011-03-16 Stefan Monnier <monnier@iro.umontreal.ca>
4636 * print.c (PRINT_CIRCLE_CANDIDATE_P): New macro.
