5 2011-06-27 Juanma Barranquero <lekktu@gmail.com>
7 * makefile.w32-in: Redesign dependencies so they reflect more
8 clearly which files are directly included by each source file,
9 and not through other includes.
11 2011-06-27 Martin Rudalics <rudalics@gmx.at>
13 * buffer.c (Qclone_number): Declare static and DEFSYM it.
14 (sort_overlays, overlay_strings): When an overlay's clone number

46 and use min_width/height from frames size_hint to set
47 min_width/height (Bug#8919).
49 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
50 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size. Fix

55 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
56 bidi_at_paragraph_end, since fast_looking_at doesn't like to be
59 2011-06-26 Chong Yidong <cyd@stupidchicken.com>
61 * process.c (wait_reading_process_output): Bypass select if
62 waiting for a cell while ignoring keyboard input, and input is

137 Integer and buffer overflow fixes (Bug#8873).
139 * print.c (printchar, strout): Check for string overflow.
140 (PRINTPREPARE, printchar, strout):
141 Don't set size unless allocation succeeds.
143 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
144 for sizes. Check for string overflow more accurately.
145 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
147 * macros.c: Integer and buffer overflow fixes.
148 * keyboard.h (struct keyboard.kbd_macro_bufsize):
149 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
150 Use ptrdiff_t, not int, for sizes.

152 Check for size-calculation overflow.
153 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
155 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
157 * lread.c: Integer overflow fixes.
158 (read_integer): Radix is now EMACS_INT, not int,
159 to improve quality of diagnostics for out-of-range radices.
160 Calculate buffer size correctly for out-of-range radices.
161 (read1): Check for integer overflow in radices, and in
163 (read_escape): Avoid int overflow.
164 (Fload, openp, read_buffer_size, read1)
165 (substitute_object_recurse, read_vector, read_list, map_obarray):

177 out-of-range doc string lengths.
178 (read_list): Don't assume file position fits in int.
179 (read_escape): Check for hex character overflow.
181 2011-06-22 Leo Liu <sdl.web@gmail.com>
183 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
184 Move to minibuffer.el.
186 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
188 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
189 The following patches are for when GLYPH_DEBUG && !XASSERT.
190 * dispextern.h (trace_redisplay_p, dump_glyph_string):
191 * dispnew.c (flush_stdout):
192 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
193 Mark as externally visible.
194 * dispnew.c (check_window_matrix_pointers): Now static.
195 * dispnew.c (window_to_frame_vpos):
196 * xfns.c (unwind_create_frame):
197 * xterm.c (x_check_font): Remove unused local.
198 * scroll.c (CHECK_BOUNDS):
199 * xfaces.c (cache_fache): Rename local to avoid shadowing.
200 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
201 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
202 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
203 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
205 (debug_method_add): Use va_list and vsprintf rather than relying
206 on undefined behavior with wrong number of arguments.
207 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
208 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
209 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
210 since we're not interested in debugging glyphs with old libraries.
211 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
212 GCC 4.6.0's static checking.
214 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
216 Integer overflow and signedness fixes (Bug#8873).
217 A few related buffer overrun fixes, too.
219 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
221 * dispextern.h (struct face.stipple):
222 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
223 (x_bitmap_mask, x_allocate_bitmap_record)
224 (x_create_bitmap_from_data, x_create_bitmap_from_file)
225 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
226 (x_create_bitmap_from_xpm_data):
227 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
228 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
230 * xfaces.c (load_pixmap):
231 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
232 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
233 (.bitmaps_last, struct x_output.icon_bitmap):
234 Use ptrdiff_t, not int, for bitmap indexes.
235 (x_allocate_bitmap_record): Check for size overflow.
236 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
238 Use ptrdiff_t, not int, for overlay counts.
239 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
240 * editfns.c (overlays_around, get_pos_property):
241 * textprop.c (get_char_property_and_overlay):
242 * xdisp.c (next_overlay_change, note_mouse_highlight):
243 * xfaces.c (face_at_buffer_position):
244 * buffer.c (OVERLAY_COUNT_MAX): New macro.
245 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
246 (Fnext_overlay_change, Fprevious_overlay_change)
247 (mouse_face_overlay_overlaps, Foverlays_in):
248 Use ptrdiff_t, not int, for sizes.
249 (overlays_at, overlays_in): Check for size-calculation overflow.
251 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
253 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
254 (x_session_initialize): Do not assume string length fits in int.
256 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
257 This is unlikely, but can occur if DPI is outlandish.
259 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
260 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
262 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
263 * xrdb.c (magic_file_p, search_magic_path):
264 Omit last arg SUFFIX; it was always 0. All callers changed.
265 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
267 * xfont.c (xfont_match): Avoid need for strlen.
269 * xfns.c: Don't assume strlen fits in int.
270 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
272 * xdisp.c (message_log_check_duplicate): Return intmax_t,
273 not unsigned long, as we prefer signed integers. All callers changed.
274 Detect integer overflow in repeat count.
275 (message_dolog): Don't assume print length fits in 39 bytes.
276 (display_mode_element): Don't assume strlen fits in int.
278 * termcap.c: Don't assume sizes fit in int and never overflow.
279 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
280 (gobble_line): Check for size-calculation overflow.
282 * minibuf.c (Fread_buffer):
283 * lread.c (intern, intern_c_string):
284 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
285 Don't assume string length fits in int.
287 * keyboard.c (parse_tool_bar_item):
288 * gtkutil.c (style_changed_cb): Avoid need for strlen.
290 * font.c: Don't assume string length fits in int.
291 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
292 Use ptrdiff_t, not int.
293 (font_intern_prop): Don't assume string length fits in int.
294 Don't assume integer property fits in fixnum.
295 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
297 * filelock.c: Fix some buffer overrun and integer overflow issues.
298 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
299 Reformulate so as not to need the command string.
300 Invoke gzip -cd rather than gunzip, as it's more portable.
301 (lock_info_type, lock_file_1, lock_file):
302 Don't assume pid_t and time_t fit in unsigned long.
303 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
304 (current_lock_owner): Prefer signed type for sizes.
305 Use memcpy, not strncpy, where memcpy is what is really wanted.
306 Don't assume (via atoi) that time_t and pid_t fit in int.
307 Check for time_t and/or pid_t out of range, e.g., via a network share.
308 Don't alloca where an auto var works fine.
310 * fileio.c: Fix some integer overflow issues.
311 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
312 Don't assume string length fits in int.
313 (directory_file_name): Don't assume string length fits in long.
314 (make_temp_name): Don't assume pid fits in int, or that its print
315 length is less than 20.
317 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
319 * coding.c (make_subsidiaries): Don't assume string length fits in int.
321 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
323 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
324 We prefer signed integers, even for size calculations.
326 * emacs.c: Don't assume string length fits in 'int'.
327 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
328 (main): Don't invoke strlen when not needed.

333 * callproc.c (getenv_internal_1, getenv_internal)
335 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
337 * lread.c (invalid_syntax): Omit length argument.
338 All uses changed. This doesn't fix a bug, but it simplifies the
339 code away from its former Hollerith-constant appearance, and it's
340 one less 'int' to worry about when looking at integer-overflow issues.
341 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
343 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
344 This didn't break anything, but it didn't help either.
345 It's confusing to put a bogus integer in a place where the actual
346 value does not matter.
347 (LIST_END_P): Remove unused macro and its bogus comment.
348 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
350 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
351 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
353 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
354 We prefer signed types, and the value cannot exceed the EMACS_INT
355 range anyway (because otherwise the length would not be representable).
356 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
357 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
358 This avoids a GCC warning when WIDE_EMACS_INT.
360 * indent.c (sane_tab_width): New function.
361 (current_column, scan_for_column, Findent_to, position_indentation)
362 (compute_motion): Use it. This is just for clarity.
363 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
365 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
367 * lisp.h (lint_assume): New macro.
368 * composite.c (composition_gstring_put_cache):
369 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
371 * editfns.c, insdel.c:
372 Omit unnecessary forward decls, to simplify future changes.
374 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
376 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
378 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
379 Use much-faster test for byte-length change.
380 Don't assume string byte-length fits in 'int'.
381 Check that character arg fits in 'int'.
382 (mapcar1): Declare byte as byte, for clarity.
384 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
386 * fns.c (concat): Catch string overflow earlier.
387 Do not rely on integer wraparound.
389 * dispextern.h (struct it.overlay_strings_charpos)
390 (struct it.selective): Now EMACS_INT, not int.
391 * xdisp.c (forward_to_next_line_start)
392 (back_to_previous_visible_line_start)
393 (reseat_at_next_visible_line_start, next_element_from_buffer):
394 Don't arbitrarily truncate the value of 'selective' to int.
396 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
398 * composite.c: Don't truncate sizes to 'int'.
399 (composition_gstring_p, composition_reseat_it)
400 (composition_adjust_point): Use EMACS_INT, not int.
401 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
402 not EMACS_UINT, for indexes.
404 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
406 * buffer.c: Include <verify.h>.
407 (struct sortvec.priority, struct sortstr.priority):
408 Now EMACS_INT, not int.
409 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
410 (struct sortstr.size, record_overlay_string)
411 (struct sortstrlist.size, struct sortlist.used):
412 Don't truncate size to int.
413 (record_overlay_string): Check for size-calculation overflow.
414 (init_buffer_once): Check at compile-time, not run-time.
416 2011-06-22 Jim Meyering <meyering@redhat.com>
418 Don't leak an XBM-image-sized buffer
419 * image.c (xbm_load): Free the image buffer after using it.
421 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
424 * composite.c (find_automatic_composition): Omit needless 'return 0;'
425 that Sun C diagnosed.
426 * fns.c (secure_hash): Fix pointer signedness issue.
427 * intervals.c (static_offset_intervals): New function.
428 (offset_intervals): Use it.
430 2011-06-21 Leo Liu <sdl.web@gmail.com>
433 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
436 * fns.c (secure_hash): Rename from crypto_hash_function and change
437 the first arg to accept symbols.
438 (Fsecure_hash): New primitive.
439 (syms_of_fns): New symbols.
441 2011-06-20 Deniz Dogan <deniz@dogan.se>
443 * process.c (Fset_process_buffer): Clarify return value in
446 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
448 * dispnew.c (add_window_display_history): Use BVAR.
450 * xdisp.c (debug_method_add): Use BVAR.
451 (check_window_end, dump_glyph_matrix, dump_glyph)
452 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
454 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
457 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
458 check till after the cache is created in init_frame_faces.
460 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
462 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
464 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
466 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
467 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
468 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
470 Improve buffer-overflow checking (Bug#8873).
471 * fileio.c (Finsert_file_contents):
472 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
473 Remove the old (too-loose) buffer overflow checks.
474 They weren't needed, since make_gap checks for buffer overflow.
475 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
476 The old code merely checked for Emacs fixnum overflow, and relied
477 on undefined (wraparound) behavior. The new code avoids undefined
478 behavior, and also checks for ptrdiff_t and/or size_t overflow.
480 * editfns.c (Finsert_char): Don't dump core with very negative counts.
481 Tune. Don't use wider integers than needed. Don't use alloca.
482 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
484 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
486 * insdel.c, lisp.h (buffer_overflow): New function.
487 (insert_from_buffer_1, replace_range, replace_range_2):
488 * insdel.c (make_gap_larger):
489 * editfns.c (Finsert_char):
490 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
492 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
494 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
496 Integer overflow and signedness fixes (Bug#8873).
498 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
499 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
501 * fileio.c: Don't assume EMACS_INT fits in off_t.
502 (emacs_lseek): New static function.
503 (Finsert_file_contents, Fwrite_region): Use it.
504 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
506 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
508 * fns.c: Don't overflow int when computing a list length.
509 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
510 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
511 truncation on 64-bit hosts. Check for QUIT every
512 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
513 faster and is responsive enough.
514 (Flength): Report an error instead of overflowing an integer.
515 (Fsafe_length): Return a float if the value is not representable
516 as a fixnum. This shouldn't happen except in contrived situations.
517 (Fnthcdr, Fsort): Don't assume list length fits in int.
518 (Fcopy_sequence): Don't assume vector length fits in int.
520 * alloc.c: Check that resized vectors' lengths fit in fixnums.
521 (header_size, word_size): New constants.
522 (allocate_vectorlike): Don't check size overflow here.
523 (allocate_vector): Check it here instead, since this is the only
524 caller of allocate_vectorlike that could cause overflow.
525 Check that the new vector's length is representable as a fixnum.
527 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
528 The previous code was bogus. For example, next_almost_prime (32)
529 returned 39, which is undesirable as it is a multiple of 3; and
530 next_almost_prime (24) returned 25, which is a multiple of 5 so
531 why was the code bothering to check for multiples of 7?
533 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
535 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
537 Variadic C functions now count arguments with ptrdiff_t.
538 This partly undoes my 2011-03-30 change, which replaced int with size_t.
539 Back then I didn't know that the Emacs coding style prefers signed int.
540 Also, in the meantime I found a few more instances where arguments
541 were being counted with int, which may truncate counts on 64-bit
542 machines, or EMACS_INT, which may be unnecessarily wide.
543 * lisp.h (struct Lisp_Subr.function.aMANY)
544 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
545 Arg counts are now ptrdiff_t, not size_t.
546 All variadic functions and their callers changed accordingly.
547 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
548 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
549 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
550 * callint.c (Fcall_interactively): Check arg count for overflow,
551 to avoid potential buffer overrun. Use signed char, not 'int',
552 for 'varies' array, so that we needn't bother to check its size
553 calculation for overflow.
554 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
555 * eval.c (apply_lambda):
556 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
557 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
558 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
560 * callint.c (Fcall_interactively): Don't use index var as event count.
562 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
563 * mem-limits.h (SIZE): Remove; no longer used.
565 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
567 Remove unnecessary casts.
568 * xterm.c (x_term_init):
569 * xfns.c (x_set_border_pixel):
570 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
571 These aren't needed now that we assume ANSI C.
573 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
574 It's more likely to cause problems (due to unsigned overflow)
577 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
579 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
581 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
583 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
585 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
587 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
589 GLYPH_CODE_FACE returns EMACS_INT, not int.
590 * dispextern.h (merge_faces):
591 * xfaces.c (merge_faces):
592 * xdisp.c (get_next_display_element, next_element_from_display_vector):
593 Don't assume EMACS_INT fits in int.
595 * character.h (CHAR_VALID_P): Remove unused parameter.
596 * fontset.c, lisp.h, xdisp.c: All uses changed.
598 * editfns.c (Ftranslate_region_internal): Omit redundant test.
600 * fns.c (concat): Minor tuning based on overflow analysis.
601 This doesn't fix any bugs. Use int to hold character, instead
602 of constantly refetching from Emacs object. Use XFASTINT, not
603 XINT, for value known to be a character. Don't bother comparing
604 a single byte to 0400, as it's always less.
606 * floatfns.c (Fexpt):
607 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
609 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
612 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
614 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
615 Without this fix, on a 64-bit host (aset S 0 4294967386) would
616 incorrectly succeed when S was a string, because 4294967386 was
617 truncated before it was used.
619 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
620 Otherwise, an out-of-range integer could cause undefined behavior
623 * composite.c: Use int, not EMACS_INT, for characters.
624 (fill_gstring_body, composition_compute_stop_pos): Use int, not
625 EMACS_INT, for values that are known to be in character range.
626 This doesn't fix any bugs but is the usual style inside Emacs and
627 may generate better code on 32-bit machines.
629 Make sure a 64-bit char is never passed to ENCODE_CHAR.
630 This is for reasons similar to the recent CHAR_STRING fix.
631 * charset.c (Fencode_char): Check that character arg is actually
632 a character. Pass an int to ENCODE_CHAR.
633 * charset.h (ENCODE_CHAR): Verify that the character argument is no
634 wider than 'int', as a compile-time check to prevent future regressions
637 * character.c (char_string): Remove unnecessary casts.
639 Make sure a 64-bit char is never passed to CHAR_STRING.
640 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
641 by silently ignoring the top 32 bits, allowing some values
642 that were far too large to be valid characters.
643 * character.h: Include <verify.h>.
644 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
645 arguments are no wider than unsigned, as a compile-time check
646 to prevent future regressions in this area.
648 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
649 (Fsubst_char_in_region):
651 * xdisp.c (decode_mode_spec_coding):
652 Adjust to CHAR_STRING's new requirement.
653 * editfns.c (Finsert_char, Fsubst_char_in_region):
654 * fns.c (concat): Check that character args are actually
655 characters. Without this test, these functions did the wrong
656 thing with wildly out-of-range values on 64-bit hosts.
658 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
659 These casts should not be needed on 32-bit hosts, either.
660 * keyboard.c (read_char):
661 * lread.c (Fload): Remove casts to unsigned.
663 * lisp.h (UNSIGNED_CMP): New macro.
664 This fixes comparison bugs on 64-bit hosts.
665 (ASCII_CHAR_P): Use it.
666 * casefiddle.c (casify_object):
667 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
668 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
669 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
670 * dispextern.h (FACE_FROM_ID):
671 * keyboard.c (read_char): Use UNSIGNED_CMP.
673 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
674 not to EMACS_INT, to avoid GCC warning.
676 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
678 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
679 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
680 isn't needed on 32-bit machines.
682 * buffer.c (Fgenerate_new_buffer_name):
683 Use EMACS_INT for count, not int.
684 (advance_to_char_boundary): Return EMACS_INT, not int.
686 * data.c (Qcompiled_function): Now static.
688 * window.c (window_body_lines): Now static.
690 * image.c (gif_load): Rename local to avoid shadowing.
692 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
693 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
694 * alloc.c (make_save_value): Integer argument is now of type
696 (mark_object): Use ptrdiff_t, not int.
697 * lisp.h (pD): New macro.
698 * print.c (print_object): Use it.
700 * alloc.c: Use EMACS_INT, not int, to count objects.
701 (total_conses, total_markers, total_symbols, total_vector_size)
702 (total_free_conses, total_free_markers, total_free_symbols)
703 (total_free_floats, total_floats, total_free_intervals)
704 (total_intervals, total_strings, total_free_strings):
705 Now EMACS_INT, not int. All uses changed.
706 (Fgarbage_collect): Compute overall total using a double, so that
707 integer overflow is less likely to be a problem. Check for overflow
708 when converting back to an integer.
709 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
710 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
711 These were 'int' variables that could overflow on 64-bit hosts;
712 they were never used, so remove them instead of repairing them.
713 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
714 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
715 Previously, this ceilinged at INT_MAX, but that doesn't work on
717 (allocate_pseudovector): Don't use EMACS_INT when int would do.
719 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
720 (allocate_vectorlike): Check for ptrdiff_t overflow.
721 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
722 when a (possibly-narrower) signed value would do just as well.
723 We prefer using signed arithmetic, to avoid comparison confusion.
725 * alloc.c: Catch some string size overflows that we were missing.
726 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
727 for convenience in STRING_BYTES_MAX.
728 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
729 The definition here is exact; the one in lisp.h was approximate.
730 (allocate_string_data): Check for string overflow. This catches
731 some instances we weren't catching before. Also, it catches
732 size_t overflow on (unusual) hosts where SIZE_MAX <= min
733 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
734 and ptrdiff_t and EMACS_INT are both 64 bits.
736 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
737 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
738 * lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.
740 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
742 * alloc.c (Fmake_string): Check for out-of-range init.
744 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
746 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
748 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
750 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
751 xg_get_default_scrollbar_width.
753 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
754 (int_gtk_range_get_value): Move to the scroll bar part of the file.
755 (style_changed_cb): Call update_theme_scrollbar_width and call
756 x_set_scroll_bar_default_width and xg_frame_set_char_size for
757 all frames (Bug#8505).
758 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
759 Call gtk_window_set_resizable if HAVE_GTK3.
760 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
761 and height if HAVE_GTK3 (Bug#8505).
762 (scroll_bar_width_for_theme): New variable.
763 (update_theme_scrollbar_width): New function.
764 (xg_get_default_scrollbar_width): Move code to
765 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
766 (xg_initialize): Call update_theme_scrollbar_width.
768 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
770 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
772 2011-06-12 Martin Rudalics <rudalics@gmx.at>
774 * frame.c (make_frame): Call other_buffer_safely instead of
777 * window.c (temp_output_buffer_show): Call display_buffer with
778 second argument Vtemp_buffer_show_specifiers and reset latter
779 immediately after the call.
780 (Vtemp_buffer_show_specifiers): New variable.
781 (auto_window_vscroll_p, next_screen_context_lines)
782 (Vscroll_preserve_screen_position): Remove leading asterisks from
785 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
787 Fix minor problems found by GCC 4.6.0 static checking.
788 * buffer.c (Qclone_number): Remove for now, as it's unused.
789 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
790 (record_buffer): Remove unused local.
791 * frame.c (other_visible_frames, frame_buffer_list): Now static.
792 (set_frame_buffer_list): Remove; unused.
793 * frame.h (other_visible_frames): Remove decl.
794 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.

800 Define only if HAVE_GPM.
801 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
802 (update_hints_inhibit): Remove; never set. All uses removed.
803 * widgetprv.h (emacsFrameClassRec): Remove decl.
804 * window.c (delete_deletable_window): Now returns void, since it
805 wasn't returning anything.
806 (compare_window_configurations): Remove unused locals.
807 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
808 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
809 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
810 the same widths as pointers. This follows up on the 2011-05-06 patch.
811 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
813 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
815 2011-06-12 Juanma Barranquero <lekktu@gmail.com>

850 buffer list implementation.
851 (other_buffer_safely): New function.
852 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
853 calls to replace_buffer_in_windows and
854 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
856 (record_buffer): Inhibit quitting and rewrite using quittable
857 functions. Run Qbuffer_list_update_hook if allowed.
858 (Frecord_buffer, Funrecord_buffer): New functions.
859 (switch_to_buffer_1, Fswitch_to_buffer): Remove. Move
860 switch-to-buffer to window.el.
861 (bury-buffer): Move to window.el.
862 (Vbuffer_list_update_hook): New variable.

880 (replace_buffer_in_windows): Implement by calling
881 Qreplace_buffer_in_windows.
882 (replace_buffer_in_all_windows): Remove with some functionality
883 moved into replace_buffer_in_windows_safely.
884 (replace_buffer_in_windows_safely): New function.
885 (select_window_norecord, select_frame_norecord): Move in front
886 of run_window_configuration_change_hook. Remove now obsolete
888 (Fset_window_buffer): Rewrite doc-string. Call
889 Qrecord_window_buffer.
890 (keys_of_window): Move binding for other-window to window.el.
892 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
894 * dispextern.h (struct image): Replace data member, whose int_val
895 and ptr_val fields were not used by anything, with a single

899 (gif_clear_image, gif_load, imagemagick_load_image)
900 (gs_clear_image, gs_load): Callers changed.
902 2011-06-10 Paul Eggert <eggert@cs.ucla.edu>

1379 Without this change, the gnutls library would invoke malloc etc.
1380 directly, which causes problems on non-SYNC_INPUT hosts, and which

1383 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
1384 xfree instead of the default malloc, realloc, free.
1385 (Fgnutls_boot): No need to check for memory allocation failure,
1386 since xmalloc does that for us.

1417 Check for integer overflow with large hash tables.
1418 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):

1422 Use it instead of discarding useful hash info with large hash values.

1424 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
1425 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
1426 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
1427 Rewrite to use FIXNUM_BITS, as this simplifies things.
1428 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
1429 Adjust signatures to match updated version of code.
1430 (consing_since_gc): Now EMACS_INT, since a single hash table can
1431 use more than INT_MAX bytes.
1433 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
1435 Make it possible to build with GCC-4.6+ -O2 -flto.
1437 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
1439 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
1441 * minibuf.c (get_minibuffer, read_minibuf_unwind):
1442 Call minibuffer-inactive-mode.
1444 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
1446 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
1447 Update dependencies.
1449 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1451 * data.c (init_data): Remove code for UTS, this system is not
1454 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1456 Don't force ./temacs to start in terminal mode.
1458 * frame.c (make_initial_frame): Initialize faces in all cases, not
1459 only when CANNOT_DUMP is defined.
1460 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
1462 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1464 * dispnew.c (add_window_display_history): Use const for the string
1465 pointer. Remove declaration, not needed.
1467 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1469 Use 'inline', not 'INLINE'.
1470 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
1471 * alloc.c, fontset.c (INLINE): Remove.
1472 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
1473 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
1474 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
1475 * gmalloc.c (register_heapinfo): Use inline unconditionally.
1476 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
1478 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
1480 Make it possible to run ./temacs.
1482 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
1483 syms_of_callproc does the same thing. Remove test for
1484 "initialized", do it in the caller.
1485 * emacs.c (main): Avoid calling set_initial_environment when dumping.
1487 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
1489 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
1490 (read_minibuf): Use get_minibuffer.
1491 (syms_of_minibuf): Use DEFSYM.
1492 (Qmetadata): New var.
1493 * data.c (Qbuffer): Don't make it static.
1494 (syms_of_data): Use DEFSYM.
1496 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
1498 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
1499 (CCL_CODE_MIN): New macro.
1501 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
1503 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
1505 * eval.c (Qdebug): Now static.
1506 * lisp.h (Qdebug): Remove decl. This reverts a part of the
1507 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
1508 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
1510 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1512 * image.c: Various fixes to ImageMagick code comments.
1513 (Fimagemagick_types): Doc fix.
1515 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
1517 Minor fixes prompted by GCC 4.6.0 warnings.
1519 * xselect.c (converted_selections, conversion_fail_tag): Now static.
1521 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
1522 (x_clipboard_manager_save_all): Move extern decl to ...
1523 * xterm.h: ... here, so that it can be checked for consistency.
1525 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
1527 * xselect.c (x_clipboard_manager_save_frame)
1528 (x_clipboard_manager_save_all): New functions.
1529 (Fx_clipboard_manager_save): Lisp function deleted.
1531 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
1532 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
1534 * xterm.h: Update prototype.
1536 2011-05-28 William Xu <william.xwl@gmail.com>
1538 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
1541 2011-05-28 Jim Meyering <meyering@redhat.com>
1543 Avoid a sign-extension bug in crypto_hash_function.
1544 * fns.c (to_uchar): Define.
1545 (crypto_hash_function): Use it to convert some newly-signed
1546 variables to unsigned, to avoid sign-extension bugs. For example,
1547 without this change, (md5 "truc") would evaluate to
1548 45723a2aff78ff4fff7fff1114760e62 rather than the expected
1549 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
1550 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
1552 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1554 Integer overflow fixes.
1556 * dbusbind.c: Serial number integer overflow fixes.
1557 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
1558 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
1559 to hold a serial number that is too large for a fixnum.
1560 (Fdbus_method_return_internal, Fdbus_method_error_internal):
1561 Check for serial numbers out of range. Decode any serial number
1562 that was so large that it became a float. (Bug#8722)
1564 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
1565 (Fdbus_call_method, Fdbus_call_method_asynchronously):
1566 Use XFASTINT rather than XUINT when numbers are nonnegative.
1567 (xd_append_arg, Fdbus_method_return_internal):
1568 (Fdbus_method_error_internal): Likewise. Also, for unsigned
1569 arguments, check that Lisp number is nonnegative, rather than
1570 silently wrapping negative numbers around. (Bug#8722)
1571 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
1574 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
1576 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
1578 ccl: add integer overflow checks
1579 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
1580 (IN_INT_RANGE): New macros.
1581 (ccl_driver): Use them to check for integer overflow when
1582 decoding a CCL program. Many of the new checks are whether XINT (x)
1583 fits in int; it doesn't always, on 64-bit hosts. The new version
1584 doesn't catch all possible integer overflows, but it's an
1585 improvement. (Bug#8719)
1587 * alloc.c (make_event_array): Use XINT, not XUINT.
1588 There's no need for unsigned here.
1590 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
1591 This follows up to the 2011-05-06 change that substituted uintptr_t
1592 for EMACS_INT. This case wasn't caught back then.
1594 Rework Fformat to avoid integer overflow issues.
1595 * editfns.c: Include <float.h> unconditionally, as it's everywhere
1596 now (part of C89). Include <verify.h>.
1597 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
1598 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
1599 (Fformat): Avoid the prepass trying to compute sizes; it was only
1600 approximate and thus did not catch overflow reliably. Instead, walk
1601 through the format just once, formatting and computing sizes as we go,
1602 checking for integer overflow at every step, and allocating a larger
1603 buffer as needed. Keep track separately whether the format is
1604 multibyte. Keep only the most-recently calculated precision, rather
1605 than them all. Record whether each argument has been converted to
1606 string. Use EMACS_INT, not int, for byte and char and arg counts.
1607 Support field widths and precisions larger than INT_MAX. Avoid
1608 sprintf's undefined behavior with conversion specifications such as %#d
1609 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
1610 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
1611 formatting out-of-range floating point numbers with int
1614 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
1616 * data.c: Avoid integer truncation in expressions involving floats.
1617 * data.c: Include <intprops.h>.
1618 (arith_driver): When there's an integer overflow in an expression
1619 involving floating point, convert the integers to floating point
1620 so that the resulting value does not suffer from catastrophic
1621 integer truncation. For example, on a 64-bit host (* 4
1622 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
1623 Do not rely on undefined behavior after integer overflow.
1625 merge count_size_as_multibyte, parse_str_to_multibyte
1626 * character.c, character.h (count_size_as_multibyte):
1627 Rename from parse_str_to_multibyte; all uses changed.
1628 Check for integer overflow.
1629 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
1630 since it's now a duplicate of the other. This is more of
1631 a character than a buffer op, so better that it's in character.c.
1632 * fns.c, print.c: Adjust to above changes.
1634 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
1636 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
1638 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
1640 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1641 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
1642 (x_clipboard_manager_save): Now static.
1643 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
1645 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
1646 (crypto_hash_function): Now static.
1647 Fix pointer signedness problems. Avoid unnecessary initializations.
1649 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
1651 * termhooks.h (Vselection_alist): Make it terminal-local.
1653 * terminal.c (create_terminal): Initialize it.
1655 * xselect.c: Support for clipboard managers.
1656 (Vselection_alist): Move to termhooks.h as terminal-local var.
1657 (LOCAL_SELECTION): New macro.
1658 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
1659 (symbol_to_x_atom): Remove gratuitous arg.
1660 (x_handle_selection_request, lisp_data_to_selection_data)
1661 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
1662 (x_own_selection, x_get_local_selection, x_convert_selection):
1663 New arg, specifying work frame. Use terminal-local Vselection_alist.
1664 (some_frame_on_display): Delete unused function.
1665 (Fx_own_selection_internal, Fx_get_selection_internal)
1666 (Fx_disown_selection_internal, Fx_selection_owner_p)
1667 (Fx_selection_exists_p): New optional frame arg.
1668 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
1669 (x_handle_selection_clear): Don't treat other terminals with the
1670 same keyboard specially. Use the terminal-local Vselection_alist.
1671 (x_clear_frame_selections): Use Frun_hook_with_args.
1673 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
1675 * xterm.h: Add support for those atoms.
1677 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
1679 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
1680 (converted_selections, conversion_fail_tag): New global variables.
1681 (x_selection_request_lisp_error): Free the above.
1682 (x_get_local_selection): Remove unnecessary code.
1683 (x_reply_selection_request): Args changed; handle arbitrary array
1684 of converted selections stored in converted_selections.
1685 Separate the XChangeProperty and SelectionNotify steps.
1686 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
1687 (x_convert_selection): New function.
1688 (x_handle_selection_event): Simplify.
1689 (x_get_foreign_selection): Don't ignore incoming requests while
1690 waiting for an answer; this will fail when we implement
1691 SAVE_TARGETS, and seems unnecessary anyway.
1692 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
1693 (Vx_sent_selection_functions): Doc fix.
1695 2011-05-26 Leo Liu <sdl.web@gmail.com>
1697 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
1699 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1701 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
1703 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
1704 for fringe update if it has periodic bitmap.
1705 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
1706 and fringe_bitmap_periodic_p.
1708 * fringe.c (get_fringe_bitmap_data): New function.
1709 (draw_fringe_bitmap_1, update_window_fringes): Use it.
1710 (update_window_fringes): Record periodicity of fringe bitmap in glyph
1711 row. Mark glyph row for fringe update if periodicity changed.
1713 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
1714 for fringe update unless it has periodic bitmap.
1716 2011-05-25 Kenichi Handa <handa@m17n.org>
1718 * xdisp.c (get_next_display_element): Set correct it->face_id for
1719 a static composition.
1721 2011-05-24 Leo Liu <sdl.web@gmail.com>
1724 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
1726 * fns.c (crypto_hash_function, Fsha1): New function.
1727 (Fmd5): Use crypto_hash_function.
1728 (syms_of_fns): Add Ssha1.
1730 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1732 * gnutls.c: Remove unused macros.
1733 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
1734 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
1735 Remove macros that are defined and never used.
1736 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
1738 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1740 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
1741 (Fx_get_selection_internal): Minor cleanup.
1742 (Fx_own_selection_internal): Rename arguments for consistency with
1745 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
1747 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
1749 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
1751 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
1753 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1755 * dispnew.c (scrolling_window): Don't exclude the case that the
1756 last enabled row in the desired matrix touches the bottom boundary.
1758 2011-05-21 Glenn Morris <rgm@gnu.org>
1760 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
1761 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
1762 and add some more files.
1764 2011-05-20 Eli Zaretskii <eliz@gnu.org>
1766 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
1767 report_file_error introduced by the change from 2011-05-07.
1769 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
1771 * systime.h (Time): Define only if emacs is defined.
1772 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
1773 where the include path doesn't have X11/X.h by default. See
1774 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
1776 2011-05-20 Kenichi Handa <handa@m17n.org>
1778 * composite.c (find_automatic_composition): Fix previous change.
1780 2011-05-20 Glenn Morris <rgm@gnu.org>
1782 * lisp.mk: New file, split from Makefile.in.
1783 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
1784 (shortlisp): Remove.
1785 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
1787 2011-05-19 Glenn Morris <rgm@gnu.org>
1789 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
1790 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
1791 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
1792 (lisp): Set the order to that of loadup.el.
1793 (shortlisp): Make it a copy of $lisp.
1794 (SOME_MACHINE_LISP): Remove.
1795 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
1796 Use just $shortlisp, not $SOME_MACHINE_LISP too.
1798 2011-05-18 Kenichi Handa <handa@m17n.org>
1800 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
1801 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
1802 (find_automatic_composition): Mostly rewrite for efficiency.
1804 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
1806 * makefile.w32-in: Update dependencies.
1808 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
1810 * menu.c: Include limits.h (fixes the MS-Windows build broken by
1811 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
1813 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
1815 Fix some integer overflow issues, such as string length overflow.
1817 * insdel.c (count_size_as_multibyte): Check for string overflow.
1819 * character.c (lisp_string_width): Check for string overflow.
1820 Use EMACS_INT, not int, for string indexes and lengths; in
1821 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
1822 the resulting string length overflows an EMACS_INT; instead,
1823 report a string overflow if no precision given. When checking for
1824 precision exhaustion, use a check that cannot possibly have
1825 integer overflow. (Bug#8675)
1826 * character.h (lisp_string_width): Adjust to new signature.
1828 * alloc.c (string_overflow): New function.
1829 (Fmake_string): Use it. This doesn't change behavior, but saves
1830 a few bytes and will simplify future changes.
1831 * character.c (string_escape_byte8): Likewise.
1832 * lisp.h (string_overflow): New decl.
1834 Fixups, following up to the user-interface timestamp change.
1835 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
1836 for UI timestamps, instead of unsigned long.
1837 * msdos.c (mouse_get_pos): Likewise.
1838 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1839 * w32gui.h (Time): Define by including "systime.h" rather than by
1840 declaring it ourselves. (Bug#8664)
1842 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
1843 * image.c (clear_image_cache): Likewise.
1845 * term.c (term_mouse_position): Don't assume time_t wraparound.
1847 Be more systematic about user-interface timestamps.
1848 Before, the code sometimes used 'Time', sometimes 'unsigned long',
1849 and sometimes 'EMACS_UINT', to represent these timestamps.
1850 This change causes it to use 'Time' uniformly, as that's what X uses.
1851 This makes the code easier to follow, and makes it easier to catch
1852 integer overflow bugs such as Bug#8664.
1853 * frame.c (Fmouse_position, Fmouse_pixel_position):
1854 Use Time, not unsigned long, for user-interface timestamps.
1855 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
1856 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
1857 * keyboard.h (last_event_timestamp): Likewise.
1858 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
1859 * menu.h (xmenu_show): Likewise.
1860 * term.c (term_mouse_position): Likewise.
1861 * termhooks.h (struct input_event.timestamp): Likewise.
1862 (struct terminal.mouse_position_hook): Likewise.
1863 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
1864 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
1865 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
1866 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
1868 * menu.h, termhooks.h: Include "systime.h", for Time.
1870 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
1871 Don't assume that the difference between two unsigned long values
1872 can fit into an integer. At this point, we know button_down_time
1873 <= event->timestamp, so the difference must be nonnegative, so
1874 there's no need to cast the result if double-click-time is
1875 nonnegative, as it should be; check that it's nonnegative, just in
1876 case. This bug is triggered when events are more than 2**31 ms
1877 apart (about 25 days). (Bug#8664)
1879 * xselect.c (last_event_timestamp): Remove duplicate decl.
1880 (x_own_selection): Remove needless cast to unsigned long.
1882 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
1883 that always fit in int. Use a sentinel instead of a counter, to
1884 avoid a temp and to allay GCC's concerns about possible int overflow.
1885 * frame.h (struct frame): Use int for menu_bar_items_used
1886 instead of EMACS_INT, since it always fits in int.
1888 * menu.c (grow_menu_items): Check for int overflow.
1890 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
1892 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
1893 Before, the code was not consistent. These values cannot exceed
1894 2**31 - 1 so there's no need to make them unsigned.
1895 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
1896 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
1897 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
1899 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
1901 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
1902 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
1903 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
1904 presumably because the widths might not match.
1906 * window.c (size_window): Avoid needless test at loop start.
1908 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
1910 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
1912 2011-05-12 Drew Adams <drew.adams@oracle.com>
1914 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
1916 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1918 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
1919 `width' to `bar_area_x' and `bar_area_width', respectively.
1920 (x_scroll_run): Take account of fringe background extension.
1922 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
1923 Rename local vars `left' and `width' to `bar_area_x' and
1924 `bar_area_width', respectively.
1925 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
1926 background extension.
1928 2011-05-10 Jim Meyering <meyering@redhat.com>
1930 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
1932 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
1934 * image.c (Finit_image_library): Return t for built-in image types,
1935 like pbm and xbm. (Bug#8640)
1937 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
1939 * w32menu.c (set_frame_menubar): Fix submenu allocation.
1941 2011-05-07 Eli Zaretskii <eliz@gnu.org>
1943 * w32console.c (Fset_screen_color): Doc fix.
1944 (Fget_screen_color): New function.
1945 (syms_of_ntterm): Defsubr it.
1947 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
1948 unlink the temporary file if Fcall_process didn't create it in the
1950 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
1951 child process will be redirected to a file specified with `:file'.
1952 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
1953 cue to call_process_cleanup not to close that handle.
1955 2011-05-07 Ben Key <bkey76@gmail.com>
1957 * makefile.w32-in: The bootstrap-temacs rule now makes use of
1958 one of two shell specific rules, either bootstrap-temacs-CMD or
1959 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
1960 to the previous implementation of the bootstrap-temacs rule.
1961 The bootstrap-temacs-CMD rule is similar to the previous
1962 implementation of the bootstrap-temacs rule except that it
1963 makes use of the ESC_CFLAGS variable instead of the CFLAGS
1966 These changes, along with some changes to nt/configure.bat,
1967 nt/gmake.defs, and nt/nmake.defs, are required to extend my
1968 earlier fix to add support for --cflags and --ldflags options
1969 that include quotes so that it works whether make uses cmd or
1972 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
1974 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
1975 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
1977 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
1978 a string. Handle both cases.
1979 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
1980 (Fdbus_register_method): Use Qinvalid_function.
1982 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
1984 * makefile.w32-in: Update dependencies.
1985 (LISP_H): Add inttypes.h and stdin.h.
1986 (PROCESS_H): Add unistd.h.
1988 2011-05-06 Eli Zaretskii <eliz@gnu.org>
1990 * lread.c: Include limits.h (fixes the MS-Windows build broken by
1991 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
1993 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
1995 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
1997 * term.c (vfatal): Remove stray call to va_end.
1998 It's not needed and the C Standard doesn't allow it here anyway.
2000 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2001 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2003 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2006 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2008 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2010 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2012 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2014 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2016 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2017 * charset.c (Fdefine_charset_internal): Don't initialize
2018 charset.code_space[15]. The value was garbage, on hosts with
2019 32-bit int (Bug#8600).
2021 * lread.c (read_integer): Be more consistent with string-to-number.
2022 Use string_to_number to do the actual conversion; this avoids
2023 rounding errors and fixes some other screwups. Without this fix,
2024 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2025 (digit_to_number): Move earlier, for benefit of read_integer.
2026 Return -1 if the digit is out of range for the base, -2 if it is
2027 not a digit in any supported base. (Bug#8602)
2029 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2031 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2032 to match comment at start of function. This also removes a
2033 GCC warning about overflow in a 32+64-bit port.
2035 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2037 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2038 Reported by Stefan Monnier in
2039 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2040 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2041 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2043 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2044 (EMACS_UINTPTR): Likewise, with uintptr_t.
2046 * lisp.h: Prefer 64-bit EMACS_INT if available.
2047 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2048 on 32-bit hosts that have 64-bit int, so that they can access
2050 However, temporarily disable this change unless the temporary
2051 symbol WIDE_EMACS_INT is defined.
2053 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2055 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2056 This removes an assumption that EMACS_INT and long are the same
2057 width as pointers. The assumption is true for Emacs porting targets
2058 now, but we want to make other targets possible.
2059 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2060 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2061 In the rest of the code, change types of integers that hold casted
2062 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2063 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2064 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2065 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2066 No need to cast type when ORing.
2067 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2068 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2069 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2070 assume EMACS_INT is the same width as char *.
2071 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2072 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2073 Remove no-longer-needed casts.
2074 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2075 (xg_tool_bar_help_callback, xg_make_tool_item):
2076 Use EMACS_INTPTR to hold an integer
2077 that will be cast to void *; this can avoid a GCC warning
2078 if EMACS_INT is not the same width as void *.
2079 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2080 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2081 (current_message_1, set_message_1):
2082 Use a local to convert to proper width without a cast.
2083 * xmenu.c (dialog_selection_callback): Likewise.
2085 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2086 Also, don't assume VALBITS / RAND_BITS is less than 5,
2087 and don't rely on undefined behavior when shifting a 1 left into
2089 * lisp.h (get_random): Change signature to match.
2091 * lread.c (hash_string): Use size_t, not int, for hash computation.
2092 Normally we prefer signed values; but hashing is special, because
2093 it's better to use unsigned division on hash table sizes so that
2094 the remainder is nonnegative. Also, size_t is the natural width
2095 for hashing into memory. The previous code used 'int', which doesn't
2096 retain enough info to hash well into very large tables.
2097 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2099 * dbusbind.c: Don't possibly lose pointer info when converting.
2100 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2101 Use XPNTR rather than XHASH, so that the high-order bits of
2102 the pointer aren't lost when converting through void *.
2104 * eval.c (Fautoload): Don't double-shift a pointer.
2106 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2108 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2110 * gnutls.c (DEF_GNUTLS_FN):
2111 * image.c (DEF_IMGLIB_FN): Make function pointers static.
2113 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
2115 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
2118 2011-05-05 Eli Zaretskii <eliz@gnu.org>
2120 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
2121 New version that can reserve upto 2GB of heap space.
2123 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
2125 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
2127 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
2129 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
2130 `gnutls_certificate_set_x509_key_file'.
2132 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
2134 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
2135 Update dependencies.
2137 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2139 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
2140 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
2141 Remove unused parameter `fildes'.
2142 * process.c (read_process_output, send_process): Don't pass it.
2144 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2146 Fix previous change: the library cache is defined in w32.c.
2147 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
2148 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
2150 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2152 Implement dynamic loading of GnuTLS on Windows.
2154 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
2155 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
2156 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2159 * gnutls.c (Qgnutls_dll): Define.
2160 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
2161 (gnutls_*): Declare function pointers.
2162 (init_gnutls_functions): New function to initialize function pointers.
2163 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
2164 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
2165 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2166 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
2167 (emacs_gnutls_write, emacs_gnutls_read)
2168 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
2169 (Fgnutls_available_p): New function.
2170 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
2171 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
2172 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
2174 * image.c: Include w32.h.
2175 (Vimage_type_cache): Delete.
2176 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
2177 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
2178 (w32_delayed_load): Move to w32.c.
2180 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
2182 * w32.c (QCloaded_from, Vlibrary_cache): Define.
2183 (w32_delayed_load): Move from image.c. When loading a library, record
2184 its filename in the :loaded-from property of the library id.
2185 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
2186 Initialize and staticpro them.
2187 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
2189 * process.c: Include lisp.h before w32.h, not after.
2190 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
2191 instead of gnutls_record_check_pending.
2193 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
2195 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
2197 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
2198 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
2201 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
2203 * xterm.c (x_set_frame_alpha): Do not set property on anything
2204 else than FRAME_X_OUTER_WINDOW (Bug#8608).
2206 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
2208 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)

2219 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
2220 (Qgnutls_bootprop_callbacks_verify): Make static.

2228 Move after wait_for_termination_1.
2230 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
2232 * sysdep.c (interruptible_wait_for_termination): New function
2233 which is like wait_for_termination, but allows keyboard
2236 * callproc.c (Fcall_process): Add (:file "file") as an option for
2238 (Fcall_process_region): Ditto.
2240 2011-04-30 Eli Zaretskii <eliz@gnu.org>
2242 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
2243 rather than `XVECTOR (FOO)->size'.
2245 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2246 inttypes.h, as a gnulib replacement is used if it not available in
2249 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2251 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
2252 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
2253 of MOST_POSITIVE_FIXNUM. (Bug#8528)
2255 * coding.c (coding_alloc_by_realloc): Error out if destination
2256 will grow beyond MOST_POSITIVE_FIXNUM.
2257 (decode_coding_emacs_mule): Abort if there isn't enough place in
2258 charbuf for the composition carryover bytes. Reserve an extra
2259 space for up to 2 characters produced in a loop.
2260 (decode_coding_iso_2022): Abort if there isn't enough place in
2261 charbuf for the composition carryover bytes.
2263 2011-04-21 Eli Zaretskii <eliz@gnu.org>
2265 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
2266 aborting when %lld or %lll format is passed.

2276 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
2278 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
2279 (SIZE_MAX): Move defn after all includes, as they might #define it.
2281 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2283 * w32.c (init_environment): Warn about defaulting HOME to C:\.
2285 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
2287 * keyboard.c (Qdelayed_warnings_hook): Define.
2288 (command_loop_1): Run `delayed-warnings-hook'
2289 if Vdelayed_warnings_list is non-nil.
2290 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
2291 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
2293 2011-04-28 Eli Zaretskii <eliz@gnu.org>
2295 * doprnt.c (doprnt): Don't return value smaller than the buffer
2296 size if the message was truncated. (Bug#8545).

2309 * makefile.w32-in: Update dependencies.
2311 2011-04-27 Eli Zaretskii <eliz@gnu.org>
2313 Improve `doprnt' and its usage. (Bug#8545)
2314 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
2315 `format_end'. Remove support for %l as a conversion specifier.
2316 Don't use xrealloc. Improve diagnostics when the %l size modifier
2317 is used. Update the commentary.
2319 * eval.c (verror): Simplify calculation of size_t.
2321 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
2324 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
2326 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
2329 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
2331 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
2332 This makes this file independent of the recent pseudovector change.
2334 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
2336 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
2338 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
2339 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
2340 Remove unused local.
2341 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
2343 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
2344 GCC 4.6.0 optimizes based on type-based alias analysis.
2345 For example, if b is of type struct buffer * and v of type struct
2346 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
2347 != &v->size, and therefore "v->size = 1; b->size = 2; return
2348 v->size;" must therefore return 1. This assumption is incorrect
2349 for Emacs, since it type-puns struct Lisp_Vector * with many other
2350 types. To fix this problem, this patch adds a new type struct
2351 vectorlike_header that documents the constraints on layout of vectors
2352 and pseudovectors, and helps optimizing compilers not get fooled
2353 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
2354 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
2355 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
2357 (XSETPVECTYPE): Rewrite in terms of new macro.
2358 (XSETPVECTYPESIZE): New macro, specifying both type and size.
2359 This is a bit clearer, and further avoids the possibility of
2360 undesirable aliasing.
2361 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
2362 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
2363 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
2364 since Lisp_Subr is a special case (no "next" field).
2365 (ASIZE): Now uses header.size rather than size.
2366 All previous uses of XVECTOR (foo)->size replaced to use this macro,
2367 to avoid the hassle of writing XVECTOR (foo)->header.size.
2368 (struct vectorlike_header): New type.
2369 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
2370 object, to help avoid aliasing.
2371 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
2372 (SUBRP): Likewise, since Lisp_Subr is a special case.
2373 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
2374 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
2375 (struct Lisp_Hash_Table): Combine first two members into a single
2376 struct vectorlike_header member. All uses of "size" and "next" members
2377 changed to be "header.size" and "header.next".
2378 * buffer.h (struct buffer): Likewise.
2379 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
2380 * frame.h (struct frame): Likewise.
2381 * process.h (struct Lisp_Process): Likewise.
2382 * termhooks.h (struct terminal): Likewise.
2383 * window.c (struct save_window_data, struct saved_window): Likewise.
2384 * window.h (struct window): Likewise.
2385 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
2386 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
2387 * buffer.c (init_buffer_once): Likewise.
2388 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
2390 * process.c (Fformat_network_address): Use local var for size,
2393 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
2395 Make the Lisp reader and string-to-float more consistent (Bug#8525)
2396 * data.c (atof): Remove decl; no longer used or needed.
2397 (digit_to_number): Move to lread.c.
2398 (Fstring_to_number): Use new string_to_number function, to be
2399 consistent with how the Lisp reader treats infinities and NaNs.
2400 Do not assume that floating-point numbers represent EMACS_INT
2401 without losing information; this is not true on most 64-bit hosts.
2402 Avoid double-rounding errors, by insisting on integers when
2403 parsing non-base-10 numbers, as the documentation specifies.
2404 * lisp.h (string_to_number): New decl, replacing ...
2405 (isfloat_string): Remove.
2406 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
2407 (read1): Do not accept +. and -. as integers; this
2408 appears to have been a coding error. Similarly, do not accept
2409 strings like +-1e0 as floating point numbers. Do not report
2410 overflow for integer overflows unless the base is not 10 which
2411 means we have no simple and reliable way to continue.
2412 Break out the floating-point parsing into a new
2413 function string_to_number, so that Fstring_to_number parses
2414 floating point numbers consistently with the Lisp reader.
2415 (digit_to_number): Move here from data.c. Make it static inline.
2416 (E_CHAR, EXP_INT): Remove, replacing with ...
2417 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
2418 (string_to_number): New function, replacing isfloat_string.
2419 This function checks for valid syntax and produces the resulting
2420 Lisp float number too. Rework it so that string-to-number
2421 no longer mishandles examples like "1.0e+". Use strtoumax,
2422 so that overflow for non-base-10 numbers is reported only when
2423 there's no portable and simple way to convert to floating point.
2425 * textprop.c (set_text_properties_1): Rewrite for clarity,
2426 and to avoid GCC warning about integer overflow.
2428 * intervals.h (struct interval): Use EMACS_INT for members
2429 where EMACS_UINT might cause problems. See
2430 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
2431 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
2432 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
2434 (offset_intervals): Tell GCC not to worry about length overflow
2435 when negating a negative length.
2437 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
2438 (overrun_check_free): Likewise.
2440 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
2441 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
2444 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2445 (gnutls_make_error): Rename local to avoid shadowing.
2446 (gnutls_emacs_global_deinit): ifdef out; not used.
2447 (Fgnutls_boot): Use const for pointer to readonly storage.
2448 Comment out unused local. Fix pointer signedness problems.
2450 * lread.c (openp): Don't stuff size_t into an 'int'.
2451 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
2452 about possible signed overflow.
2454 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
2455 (GDK_KEY_g): Don't define if already defined.
2456 (xg_prepare_tooltip): Avoid pointer signedness problem.
2457 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
2459 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
2460 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
2462 * xfns.c (Fx_window_property): Simplify a bit,
2463 to make a bit faster and to avoid GCC 4.6.0 warning.
2464 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
2466 * fns.c (internal_equal): Don't assume size_t fits in int.
2468 * alloc.c (compact_small_strings): Tighten assertion a little.
2470 Replace pEd with more-general pI, and fix some printf arg casts.
2471 * lisp.h (pI): New macro, generalizing old pEd macro to other
2472 conversion specifiers. For example, use "...%"pI"d..." rather
2473 than "...%"pEd"...".
2474 (pEd): Remove. All uses replaced with similar uses of pI.
2475 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
2476 * alloc.c (check_pure_size): Don't overflow by converting size to int.
2477 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
2478 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
2479 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
2480 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
2481 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
2483 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
2484 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
2485 * print.c (safe_debug_print, print_object): Likewise.
2486 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
2488 Use pI instead of if-then-else-abort. Use %p to avoid casts,
2489 avoiding the 0 flag, which is not portable.
2490 * process.c (Fmake_network_process): Use pI to avoid cast.
2491 * region-cache.c (pp_cache): Likewise.
2492 * xdisp.c (decode_mode_spec): Likewise.
2493 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
2494 behavior on 64-bit hosts with printf arg.
2495 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
2496 (x_stop_queuing_selection_requests): Likewise.
2497 (x_get_window_property): Don't truncate byte count to an 'int'
2500 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
2501 here, since it parses constructs like leading '-' and spaces,
2502 which are not wanted; and it overflows with large numbers.
2503 Instead, simply match F[0-9]+, which is what is wanted anyway.
2505 * alloc.c: Remove unportable assumptions about struct layout.
2506 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
2507 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
2508 (allocate_vectorlike, make_pure_vector): Use the new macros,
2509 plus offsetof, to remove unportable assumptions about struct layout.
2510 These assumptions hold on all porting targets that I know of, but
2511 they are not guaranteed, they're easy to remove, and removing them
2512 makes further changes easier.
2514 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
2515 This doesn't fix a bug but makes the code clearer.
2516 (string_overrun_cookie): Now const. Use initializers that
2517 don't formally overflow signed char, to avoid warnings.
2518 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
2519 can cause Emacs to crash when string overrun checking is enabled.
2520 (allocate_buffer): Don't assume sizeof (struct buffer) is a
2521 multiple of sizeof (EMACS_INT); it need not be, if
2522 alignof(EMACS_INT) < sizeof (EMACS_INT).
2523 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
2525 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
2527 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
2529 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>

2532 supposed to be handshaking. (Bug#8556)
2533 Reported by Paul Eggert <eggert@cs.ucla.edu>.
2535 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

2545 * alloc.c (check_sblock, check_string_bytes)
2546 (check_string_free_list): Convert to standard C.
2548 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
2550 * w32.c (emacs_gnutls_push): Fix typo.
2552 2011-04-25 Eli Zaretskii <eliz@gnu.org>
2554 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
2555 "cast to pointer from integer of different size".
2557 Improve doprnt and its use in verror. (Bug#8545)
2558 * doprnt.c (doprnt): Document the set of format control sequences
2559 supported by the function. Use SAFE_ALLOCA instead of always
2562 * eval.c (verror): Don't limit the buffer size at size_max-1, that
2563 is one byte too soon. Don't use xrealloc; instead xfree and
2566 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
2568 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

2572 gnutls_global_initialized. Added internals for the
2573 :verify-hostname-error, :verify-error, and :verify-flags
2574 parameters of `gnutls-boot' and documented those parameters in the
2575 docstring. Start callback support.
2576 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
2577 unless a fatal error occured. Call gnutls_alert_send_appropriate
2578 on error. Return error code.
2579 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
2580 (emacs_gnutls_read): Likewise.
2581 (Fgnutls_boot): Return handshake error code.

2650 * doprnt.c: Include limits.h.
2651 (SIZE_MAX): New macro.
2652 (doprnt): Return a size_t value. 2nd arg is now size_t.
2653 Many local variables are now size_t instead of int or unsigned.
2654 Improve overflow protection. Support `l' modifier for integer
2655 conversions. Support %l conversion. Don't assume an EMACS_INT
2656 argument for integer conversions and for %c.
2658 * lisp.h (doprnt): Restore prototype.
2660 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
2663 * Makefile.in (base_obj): Add back doprnt.o.
2665 * deps.mk (doprnt.o): Add back prerequisites.
2666 (callint.o): Depend on character.h.
2668 * eval.c (internal_lisp_condition_case): Include the handler
2669 representation in the error message.
2670 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
2671 when breaking from the loop.
2673 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
2675 * callint.c (Fcall_interactively): When displaying error message
2676 about invalid control letter, pass the character's codepoint, not
2677 a pointer to its multibyte form. Improve display of the character
2678 in octal and display also its hex code.
2680 * character.c (char_string): Use %x to display the (unsigned)
2681 codepoint of an invalid character, to avoid displaying a bogus
2684 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
2685 `error', not SYMBOL_NAME itself.

2688 character arguments to `error'.
2690 * charset.c (check_iso_charset_parameter): Fix incorrect argument
2691 to `error' in error message about FINAL_CHAR argument. Make sure
2692 FINAL_CHAR is a character, and use %c when it is passed as
2693 argument to `error'.
2695 2011-04-23 Eli Zaretskii <eliz@gnu.org>
2697 * s/ms-w32.h (localtime): Redirect to sys_localtime.

2774 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
2775 so that we aren't warned about unused symbols.

2786 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
2787 (x_dispatch_event): Declare static if USE_GTK, and
2788 define if USE_GTK || USE_X_TOOLKIT.
2789 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
2790 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
2791 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
2792 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
2794 * xmenu.c (menu_help_callback): Pointer type fixes.
2795 Use const pointers when pointing at readonly data. Avoid pointer
2797 (FALSE): Remove unused macro.

2800 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.
2802 * menu.c (push_submenu_start, push_submenu_end): Do not define unless

2882 * nsfont.m: Fixed bugs in ns_get_family and
2883 ns_descriptor_to_entity that were caused by using free to
2884 deallocate memory blocks that were allocated by xmalloc (via
2885 xstrdup). This caused Emacs to crash when compiled with
2886 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
2887 --enable-checking=xmallocoverrun). xfree is now used to
2888 deallocate these memory blocks.

2905 (emacs_read, emacs_write): Use it.
2906 * process.c (send_process): Adjust to the new signatures of
2907 emacs_write and emacs_gnutls_write. Do not attempt to store

3262 (catchlist, handlerlist, mark_backtrace):
3263 Declare only if BYTE_MARK_STACK.
3264 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
3265 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
3266 (message_enable_multibyte): Remove decl.
3267 (free_misc, interval_free_list, float_block, float_block_index):
3268 (n_float_blocks, float_free_list, cons_block, cons_block_index):
3269 (cons_free_list, last_marked_index):
3271 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
3272 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
3273 (mark_backtrace): Define only if BYTE_MARK_STACK.
3274 * xdisp.c (message_enable_multibyte): Now static.
3276 Declare Lisp_Object Q* variables to be 'static' if not exported.
3277 This makes it easier for human readers (and static analyzers)
3278 to see whether these variables are used from other modules.
3279 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
3280 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
3281 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

3284 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
3285 * xmenu.c, xselect.c:
3286 Declare Q* vars static if they are not used in other modules.
3287 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
3288 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
3289 Remove decls of unexported vars.
3290 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
3292 * lisp.h (DEFINE_FUNC): Make sname 'static'.
3294 Make Emacs functions such as Fatom 'static' by default.
3295 This makes it easier for human readers (and static analyzers)
3296 to see whether these functions can be called from other modules.
3297 DEFUN now defines a static function. To make the function external
3298 so that it can be used in other C modules, use the new macro DEFUE.
3299 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
3300 (Finit_image_library):
3301 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
3302 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
3303 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
3304 Remove decls, since these functions are now static.
3305 (Funintern, Fget_internal_run_time): New decls, since these functions
3306 were already external.
3308 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
3309 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
3310 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

3312 * keyboard.c, keymap.c, lread.c:
3313 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
3314 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
3315 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
3316 Mark functions with DEFUE instead of DEFUN,
3317 if they are used in other modules.
3318 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
3319 decls for now-static functions.
3320 * buffer.h (Fdelete_overlay): Remove decl.
3321 * callproc.c (Fgetenv_internal): Mark as internal.

3333 (Fremove_list_of_text_properties): Remove decls.
3334 * keyboard.c (Fthis_command_keys): Remove decl.
3335 (Fcommand_execute): New forward static decl.
3336 * keymap.c (Flookup_key): New forward static decl.
3337 (Fcopy_keymap): Now static.
3338 * keymap.h (Flookup_key): Remove decl.
3339 * process.c (Fget_process): New forward static decl.
3340 (Fprocess_datagram_address): Mark as internal.

3351 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
3353 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
3356 2011-04-13 Eli Zaretskii <eliz@gnu.org>
3358 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
3359 when at ZV. (Bug#8487)
3361 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
3363 * charset.c (Fclear_charset_maps): Use xfree instead of free.
3365 * keyboard.c (parse_tool_bar_item): Likewise.
3366 * sound.c (sound_cleanup, alsa_close): Likewise.
3367 * termcap.c (tgetent): Likewise.
3368 * xfns.c (x_default_font_parameter): Likewise.
3369 * xsettings.c (read_and_apply_settings): Likewise.
3371 * alloc.c (overrun_check_malloc, overrun_check_realloc)
3372 (overrun_check_free): Protoize.
3374 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
3376 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
3377 since callers should never pass a negative size.
3378 Change the signature to match that of plain 'read' and 'write'; see
3379 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
3380 * lisp.h: Update prototypes of emacs_write and emacs_read.
3382 2011-04-11 Eli Zaretskii <eliz@gnu.org>
3384 * xdisp.c (redisplay_window): Don't try to determine the character
3385 position of the scroll margin if the window start point w->startp
3386 is outside the buffer's accessible region. (Bug#8468)
3388 2011-04-10 Eli Zaretskii <eliz@gnu.org>
3390 Fix write-region and its subroutines for buffers > 2GB.
3391 * fileio.c (a_write, e_write): Modify declaration of arguments and
3392 local variables to support buffers larger than 2GB.
3393 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
3395 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
3396 argument, local variables, and return value.
3398 * lisp.h: Update prototypes of emacs_write and emacs_read.
3400 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
3402 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
3404 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
3406 Fix more problems found by GCC 4.6.0's static checks.
3408 * xdisp.c (vmessage): Use a better test for character truncation.
3410 * charset.c (load_charset_map): <, not <=, for optimization,
3411 and to avoid potential problems with integer overflow.
3412 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
3413 * casetab.c (set_identity, shuffle): Likewise.
3414 * editfns.c (Fformat): Likewise.
3415 * syntax.c (skip_chars): Likewise.
3417 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
3418 This also lets GCC 4.6.0 generate slightly better loop code.
3420 * callint.c (Fcall_interactively): <, not <=, for optimization.
3421 (Fcall_interactively): Count the number of arguments produced,
3422 not the number of arguments given. This is simpler and lets GCC
3423 4.6.0 generate slightly better code.
3425 * ftfont.c: Distingish more carefully between FcChar8 and char.
3426 The previous code passed unsigned char * to a functions like
3427 strlen and xstrcasecmp that expect char *, which does not
3428 conform to the C standard.
3429 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
3430 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
3431 char * when the C standard requires it.
3433 * keyboard.c (read_char): Remove unused var.
3435 * eval.c: Port to Windows vsnprintf (Bug#8435).
3437 (SIZE_MAX): Define if the headers do not.
3438 (verror): Do not give up if vsnprintf returns a negative count.
3439 Instead, grow the buffer. This ports to Windows vsnprintf, which
3440 does not conform to C99. Problem reported by Eli Zaretskii.
3441 Also, simplify the allocation scheme, by avoiding the need for
3442 calling realloc, and removing the ALLOCATED variable.
3444 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
3446 Remove invocations of doprnt, as Emacs now uses vsnprintf.
3447 But keep the doprint source code for now, as we might revamp it
3448 and use it again (Bug#8435).
3449 * lisp.h (doprnt): Remove.
3450 * Makefile.in (base_obj): Remove doprnt.o.
3451 * deps.mk (doprnt.o): Remove.
3453 error: Print 32- and 64-bit integers portably (Bug#8435).
3454 Without this change, on typical 64-bit hosts error ("...%d...", N)
3455 was used to print both 32- and 64-bit integers N, which relied on
3457 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
3459 * lisp.h (error, verror): Mark as printf-like functions.
3460 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
3461 Report overflow in size calculations when allocating printf buffer.
3462 Do not truncate output string at its first null byte.
3463 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
3464 Truncate the output at a character boundary, since vsnprintf does not
3466 * charset.c (check_iso_charset_parameter): Convert internal
3467 character to string before calling 'error', since %c now has the
3469 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
3470 overflow when computing char to be passed to 'error'. Do not
3471 pass Lisp_Object to 'error'; pass the integer instead.
3472 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
3473 formatted with plain %d.
3475 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
3477 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
3479 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
3481 * xterm.c (x_catch_errors): Remove duplicate declaration.
3483 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
3485 * xdisp.c, lisp.h (message_nolog): Remove; unused.
3487 2011-04-10 Jim Meyering <meyering@redhat.com>
3489 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
3490 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
3491 return ssize_t not "int", and use size_t as the buffer length.
3492 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
3493 * gnutls.h: Update declarations.
3494 * process.c (read_process_output): Use ssize_t, to match.
3495 (send_process): Likewise.
3497 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3499 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
3501 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
3503 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
3504 Use unsigned char, to match FcChar8 type definition.
3506 * xterm.c (handle_one_xevent):
3507 * xmenu.c (create_and_show_popup_menu):
3508 * xselect.c (x_decline_selection_request)
3509 (x_reply_selection_request): Avoid type-punned deref of X events.
3511 2011-04-09 Eli Zaretskii <eliz@gnu.org>
3513 Fix some uses of `int' instead of EMACS_INT.
3514 * search.c (string_match_1, fast_string_match)
3515 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
3516 (scan_buffer, find_next_newline_no_quit)
3517 (find_before_next_newline, search_command, Freplace_match)
3518 (Fmatch_data): Make some `int' variables be EMACS_INT.
3520 * xdisp.c (display_count_lines): 3rd argument and return value now
3521 EMACS_INT. All callers changed.
3522 (pint2hrstr): Last argument is now EMACS_INT.
3524 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
3525 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
3526 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
3527 (decode_coding_utf_16, decode_coding_emacs_mule)
3528 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
3529 (decode_coding_ccl, decode_coding_charset)
3530 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
3531 (decode_coding_iso_2022, decode_coding_emacs_mule)
3532 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
3533 <char_offset, last_offset>: Declare EMACS_INT.
3534 (encode_coding_utf_8, encode_coding_utf_16)
3535 (encode_coding_emacs_mule, encode_invocation_designation)
3536 (encode_designation_at_bol, encode_coding_iso_2022)
3537 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
3538 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
3540 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
3541 (encode_invocation_designation): Last argument P_NCHARS is now
3543 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
3544 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
3546 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
3549 * ccl.c (Fccl_execute_on_string): Declare some variables
3552 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

3564 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
3566 * keyboard.c (read_char): Call Lisp function help-form-show,
3567 instead of using internal_with_output_to_temp_buffer.
3568 (Qhelp_form_show): New var.
3569 (syms_of_keyboard): Use DEFSYM macro.
3571 * print.c (internal_with_output_to_temp_buffer): Function deleted.
3573 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
3575 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
3577 * process.c (Flist_processes): Remove to Lisp.
3578 (list_processes_1): Delete.

3584 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
3586 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
3588 Fix more problems found by GCC 4.6.0's static checks.
3590 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
3592 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
3594 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
3596 * xdisp.c (vmessage): Mark as a printf-like function.
3598 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
3600 * sound.c (sound_warning): Don't crash if arg contains a printf format.
3602 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
3603 printf-like functions.
3604 (tiff_load): Add casts to remove these marks before passing them
3605 to system-supplied API.
3607 * eval.c (Fsignal): Remove excess argument to 'fatal'.
3609 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
3610 This avoids several warnings with gcc -Wstrict-overflow.
3611 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
3612 directly, rather than having caller test rule sign. This avoids
3613 some unnecessary tests.
3614 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
3615 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
3616 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

3619 (xfont_open): Avoid unnecessary tests.
3621 * composite.c (composition_gstring_put_cache): Use unsigned integer.

3624 Use EMACS_INT, not int, for length.
3626 * composite.h (COMPOSITION_DECODE_REFS): New macro,
3627 breaking out part of COMPOSITION_DECODE_RULE.
3628 (COMPOSITION_DECODE_RULE): Use it.
3629 * composite.c (get_composition_id): Remove unused local vars,
3630 by using the new macro.
3632 * textprop.c (set_text_properties_1): Change while to do-while,
3633 since the condition is always true at first.
3635 * intervals.c (graft_intervals_into_buffer): Mark var as used.
3636 (interval_deletion_adjustment): Return unsigned value.
3639 * process.c (list_processes_1, create_pty, read_process_output):

3648 * syntax.c (scan_words): Remove var that was set but not used.
3649 (update_syntax_table): Use unsigned instead of int.
3651 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

3653 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
3655 * print.c (print_error_message): Avoid int overflow.
3657 * font.c (font_list_entities): Redo for clarity,
3658 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
3660 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
3661 (font_score): Avoid potential overflow in diff calculation.
3663 * fns.c (substring_both): Remove var that is set but not used.
3664 (sxhash): Redo loop for clarity and to avoid wraparound warning.
3666 * eval.c (funcall_lambda): Rename local to avoid shadowing.
3668 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
3669 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
3670 can always succeed if overflow has undefined behavior.
3672 * search.c (boyer_moore, wordify): Remove vars set but not used.
3673 (wordify): Omit three unnecessary tests.
3675 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
3676 All callers changed. This avoids the need for an unused var.
3678 * casefiddle.c (casify_region): Remove var that is set but not used.
3680 * dired.c (file_name_completion): Remove var that is set but not used.
3682 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
3684 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
3685 (Finsert_file_contents): Remove unnecessary code checking fd.
3687 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
3688 Check for integer overflow on size calculations.
3690 * buffer.c (Fprevious_overlay_change): Remove var that is set
3693 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
3694 Remove vars that are set but not used.
3695 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
3696 (timer_check_2): Mark vars as initialized.
3698 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
3700 * image.c (lookup_image): Remove var that is set but not used.
3701 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
3703 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
3704 that are set but not used.
3706 * xfns.c (make_invisible_cursor): Don't return garbage
3707 if XCreateBitmapFromData fails (Bug#8410).
3709 * xselect.c (x_get_local_selection, x_handle_property_notify):
3710 Remove vars that are set but not used.
3712 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
3713 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
3715 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
3716 Remove var that is set but not used.
3717 (scroll_bar_windows_size): Now size_t, not int.

3734 that is set but not used.
3736 * print.c (print_object): Remove var that is set but not used.
3738 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
3739 The gnulib version avoids calling malloc in the usual case,
3740 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
3741 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
3742 * filelock.c (current_lock_owner): Likewise.
3743 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

3767 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
3768 and thereabouts. All callers changed.
3769 (get_per_char_metric): Remove parameter `f', unused since
3770 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

3782 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
3784 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

3789 Add lexical binding.
3791 * window.c (Ftemp_output_buffer_show): New fun.
3792 (Fsave_window_excursion):

3795 * lread.c (lisp_file_lexically_bound_p): New function.
3796 (Fload): Bind Qlexical_binding.
3797 (readevalloop): Remove `evalfun' arg.
3798 Bind Qinternal_interpreter_environment.
3799 (Feval_buffer): Bind Qlexical_binding.
3800 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
3802 (syms_of_lread): Declare `lexical-binding'.
3804 * lisp.h (struct Lisp_Symbol): New field `declared_special'.

3807 (menu_item_eval_property): Use it.
3809 * image.c (parse_image_spec): Use Ffunctionp.
3811 * fns.c (concat, mapcar1): Accept byte-code-functions.
3813 * eval.c (Fsetq): Handle lexical vars.
3814 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
3815 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
3816 (FletX, Flet): Obey lexical binding.
3817 (Fcommandp): Handle closures.
3818 (Feval): New `lexical' arg.
3819 (eval_sub): New function extracted from Feval. Use it almost
3820 everywhere where Feval was used. Look up vars in lexical env.
3822 (Ffunctionp): Move from subr.el.
3823 (Ffuncall): Handle closures.
3824 (apply_lambda): Remove `eval_flags'.
3825 (funcall_lambda): Handle closures and new byte-code-functions.
3826 (Fspecial_variable_p): New function.
3827 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
3828 but without exporting it to Lisp.
3830 * doc.c (Fdocumentation, store_function_docstring):
3831 * data.c (Finteractive_form): Handle closures.
3833 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
3836 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
3838 (exec_byte_code): New function extracted from Fbyte_code to handle new
3839 calling convention for byte-code-functions. Add new byte-codes.

3851 * xdisp.c (SCROLL_LIMIT): New macro.
3852 (try_scrolling): Use it when setting scroll_limit.
3853 Limit scrolling to 100 screen lines.
3854 (redisplay_window): Even when falling back on "recentering",
3855 position point in the window according to scroll-conservatively,
3856 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
3858 (try_scrolling): When point is above the window, allow searching
3859 as far as scroll_max, or one screenful, to compute vertical
3860 distance from PT to the scroll margin position. This prevents
3861 try_scrolling from unnecessarily failing when
3862 scroll-conservatively is set to a value slightly larger than the
3863 window height. Clean up the case of PT below the margin at bottom
3864 of window: scroll_max can no longer be INT_MAX. When aggressive
3865 scrolling is in use, don't let point enter the opposite scroll
3866 margin as result of the scroll.
3867 (syms_of_xdisp) <scroll-conservatively>: Document the
3868 threshold of 100 lines for never-recentering scrolling.

3875 (message_log_check_duplicate): Remove parameters `prev_bol' and
3876 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
3877 (redisplay_internal): Remove parameter `preserve_echo_area',
3878 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
3880 * indent.c (Fvertical_motion):
3881 * window.c (window_scroll_pixel_based, Frecenter):
3882 Don't pass `need_y_p' to `move_it_by_lines'.
3884 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
3886 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
3887 steal a few bits to be more compact.
3888 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
3889 Remove unneeded casts.
3891 * bytecode.c (Fbyte_code): CAR and CDR can GC.
3893 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
3895 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
3896 binding" message (bug#7967).
3898 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
3900 Fix more problems found by GCC 4.6.0's static checks.
3902 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
3903 Remove unused local var.
3905 * editfns.c (Fmessage_box): Remove unused local var.
3907 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
3908 (note_mode_line_or_margin_highlight, note_mouse_highlight):
3909 Omit unused local vars.
3910 * window.c (shrink_windows): Omit unused local var.
3911 * menu.c (digest_single_submenu): Omit unused local var.
3912 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
3913 Omit unused local var.
3915 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
3916 Don't assume string length fits in int.
3917 (keyremap_step, read_key_sequence): Use size_t for sizes.
3918 (read_key_sequence): Don't check last_real_key_start redundantly.
3920 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
3921 instead of alloca (Bug#8344).
3923 * eval.c (Fbacktrace): Don't assume nargs fits in int.

3933 * cm.c (calccost): Turn while-do into do-while, for clarity.
3935 * keyboard.c (syms_of_keyboard): Use the same style as later
3936 in this function when indexing through an array. This also
3937 works around GCC bug 48267.
3939 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
3941 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
3943 * chartab.c (sub_char_table_ref_and_range): Redo for slight
3944 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
3946 * keyboard.c, keyboard.h (num_input_events): Now size_t.
3947 This avoids undefined behavior on integer overflow, and is a bit
3948 more convenient anyway since it is compared to a size_t variable.
3950 Variadic C functions now count arguments with size_t, not int.
3951 This avoids an unnecessary limitation on 64-bit machines, which
3952 caused (substring ...) to crash on large vectors (Bug#8344).
3953 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.

3963 * frame.c (x_set_frame_parameters): Likewise.
3964 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
3965 0 if not found, not -1. All callers changed.
3967 * alloc.c (garbage_collect): Don't assume stack size fits in int.
3968 (stack_copy_size): Now size_t, not int.
3969 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
3971 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
3973 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
3974 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
3975 All callers changed.

3994 Vcommand_hook_internal.

3997 (funcall_nil, funcall_not): New functions.
3998 (run_hook_with_args): Call each function through a `funcall' argument.

4017 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
4018 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

4091 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
4093 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
4094 incurred during fontification.

4170 * emacs.c (Fkill_emacs):
4171 * editfns.c (save_excursion_restore):
4172 * cmds.c (internal_self_insert):
4173 * callint.c (Fcall_interactively):
4174 * buffer.c (Fkill_all_local_variables):
4175 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4177 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4178 unconditionnaly since it does the check itself.
4180 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4182 Fix more problems found by GCC 4.5.2's static checks.
4184 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4185 the first time through the loop, since we know p0 < p1 then.
4186 This also avoids a gcc -Wstrict-overflow warning.
4188 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4189 leading to a memory leak, possible in functions like
4190 load_charset_map_from_file that can allocate an unbounded number
4191 of objects (Bug#8318).
4193 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4194 that could (at least in theory) be that large.
4196 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4197 This is less likely to overflow, and avoids undefined behavior if
4198 overflow does occur. All callers changed. Use strtoul to scan
4199 for the unsigned long integer.
4200 (pint2hrstr): Simplify and tune code slightly.
4201 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
4203 * scroll.c (do_scrolling): Work around GCC bug 48228.
4204 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

4207 This also avoids a warning with gcc -Wstrict-overflow.
4208 (validate_x_resource_name): Simplify count usage.
4209 This also avoids a warning with gcc -Wstrict-overflow.
4211 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4214 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4216 * process.c (Fmake_network_process): Use socklen_t, not int,
4217 where POSIX says socklen_t is required in portable programs.
4218 This fixes a porting bug on hosts like 64-bit HP-UX, where
4219 socklen_t is wider than int (Bug#8277).
4220 (Fmake_network_process, server_accept_connection):
4221 (wait_reading_process_output, read_process_output):

4234 Make tparam.h and terminfo.c consistent.
4235 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4236 Include tparam.h instead, since it declares them.
4237 * cm.h (PC): Remove extern decl; tparam.h now does this.
4238 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4239 * terminfo.c: Include tparam.h, to check interfaces.
4240 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4241 (tparam): Adjust signature to match interface in tparam.h;
4242 this removes some undefined behavior. Check that outstring and len
4243 are zero, which they always are with Emacs.
4244 * tparam.h (PC, BC, UP): New extern decls.
4246 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
4247 (xftfont_open): Rename locals to avoid shadowing.
4249 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

4265 (composition_update_it): Mark var as initialized.
4266 (find_automatic_composition): Mark vars as initialized,
4267 with a FIXME (Bug#8290).
4269 character.h: Rename locals to avoid shadowing.
4270 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
4271 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
4272 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
4273 (BUF_DEC_POS): Be more systematic about renaming local temporaries
4276 * textprop.c (property_change_between_p): Remove; unused.
4278 * intervals.c (interval_start_pos): Now static.
4280 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
4282 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
4283 Rename locals to avoid shadowing.
4285 * sound.c (wav_play, au_play, Fplay_sound_internal):
4286 Fix pointer signedness.
4287 (alsa_choose_format): Remove unused local var.
4288 (wav_play): Initialize a variable to 0, to prevent undefined
4289 behavior (Bug#8278).
4291 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
4293 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
4295 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
4296 clobbering (Bug#8298).
4297 * sysdep.c (sys_subshell): Likewise.
4298 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
4300 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
4301 This should get cleaned up, so that child_setup has the
4302 same signature on all platforms.
4304 * callproc.c (call_process_cleanup): Now static.
4305 (relocate_fd): Rename locals to avoid shadowing.
4307 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
4309 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
4310 not to be necessary, and produces flickering.
4312 2011-03-20 Glenn Morris <rgm@gnu.org>
4314 * config.in: Remove file.
4316 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
4318 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
4319 are now in src/globals.h.
4320 (syms_of_minibuf): Remove spurious & from previous change.
4322 2011-03-20 Leo <sdl.web@gmail.com>
4324 * minibuf.c (completing-read-function): New variable.
4325 (completing-read-default): Rename from completing-read.
4326 (completing-read): Call completing-read-function.
4328 2011-03-19 Juanma Barranquero <lekktu@gmail.com>

4331 Read color file from absolute filename (bug#8250).
4333 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
4335 * makefile.w32-in: Update dependencies.
4337 2011-03-17 Eli Zaretskii <eliz@gnu.org>
4339 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
4341 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

4346 (sigchld_handler): Now static.
4348 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

4355 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
4356 * process.c (allocate_pty): Don't declare stb unless it's needed.
4358 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
4359 (CONSTANTLIM): Remove; unused.
4360 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
4361 Define only if needed.
4363 * unexelf.c (unexec): Name an expression,
4364 to avoid gcc -Wbad-function-cast warning.
4365 Use a different way to cause a compilation error if anyone uses
4366 n rather than nn, a way that does not involve shadowing.
4367 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
4369 * deps.mk (unexalpha.o): Remove; unused.
4371 New file unexec.h, the (simple) interface for unexec (Bug#8267).
4372 * unexec.h: New file.
4373 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
4374 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
4376 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
4377 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
4378 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

4389 (Fload, readevalloop, read1): Rename locals to avoid shadowing.
4391 * print.c (Fredirect_debugging_output): Fix pointer signedess.
4393 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
4394 warning when compiling print.c.
4396 * font.c (font_unparse_fcname): Abort in an "impossible" situation
4397 instead of using an uninitialized var.
4398 (font_sort_entities): Mark var as initialized.
4400 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
4402 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

4434 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
4435 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
4436 some of which prompt warnings from gcc -Wbad-function-cast.
4437 (Fformat_time_string, Fencode_time, Finsert_char):
4438 (Ftranslate_region_internal, Fformat):
4439 Rename or remove local vars to avoid shadowing.

4457 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
4458 Rename locals to avoid shadowing.
4459 (mark_stack): Move local variables into the #ifdef region where
4461 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
4462 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
4464 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
4465 (GC_STRING_CHARS): Remove; not used.
4466 (Fmemory_limit): Cast sbrk's returned value to char *.

4469 avoids undefined behavior in theory.
4471 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
4473 Use functions, not macros, for up- and down-casing (Bug#8254).
4474 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4475 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
4476 to use the following functions instead of these macros.
4477 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
4478 EMACS_INT, since callers assume the returned value fits in int.
4479 (upcase1): Likewise, for UPCASE_TABLE.
4480 (uppercasep, lowercasep, upcase): New static inline functions.
4481 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

4487 (regex_compile, re_search_2, re_match_2_internal):
4488 Remove unused local vars.
4489 (FREE_VAR): Rewrite so as not to use empty "else",
4490 which gcc can warn about.
4491 (regex_compile, re_match_2_internal): Mark locals as initialized.
4492 (RETALLOC_IF): Define only if needed.
4493 (WORDCHAR_P): Likewise. This one is never needed, but is used
4494 only in a comment talking about a compiler bug, so put inside
4495 the #if 0 of that comment.
4496 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
4497 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
4500 * search.c (boyer_moore): Rename locals to avoid shadowing.
4501 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
4502 (PREV_CHAR_BOUNDARY): Likewise.
4504 * search.c (simple_search): Remove unused var.
4506 * dired.c (compile_pattern): Move decl from here ...

4519 (casify_region): Mark local as initialized.
4521 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
4523 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
4524 New macros, so that the caller can use some names other than
4525 gcpro1, gcpro2, etc.
4526 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
4528 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
4529 argument, for consistency with GCPRO2_VAR, etc: it is now the
4530 prefix of the variable, not the variable itself. All uses
4532 * dired.c (directory_files_internal, file_name_completion):
4533 Rename locals to avoid shadowing.
4535 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
4536 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
4537 dired.c's scmp function, had undefined behavior.
4538 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
4539 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
4540 * buffer.h: ... to here, because these macros use current_buffer,
4541 and the new implementation with inline functions needs to have
4542 current_buffer in scope now, rather than later when the macros
4544 (downcase, upcase1): New static inline functions.
4545 (DOWNCASE, UPCASE1): Reimplement using these functions.
4546 This avoids undefined behavior in expressions like
4547 DOWNCASE (x) == DOWNCASE (y), which previously suffered
4548 from race conditions in accessing the global variables
4549 case_temp1 and case_temp2.
4550 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
4551 * lisp.h (case_temp1, case_temp2): Remove their decls.
4552 * character.h (ASCII_CHAR_P): Move from here ...
4553 * lisp.h: ... to here, so that the inline functions mentioned
4556 * dired.c (directory_files_internal_unwind): Now static.
4558 * fileio.c (file_name_as_directory, directory_file_name):
4559 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
4561 (file_name_as_directory): Use const pointers when appropriate.
4562 (Fexpand_file_name): Likewise. In particular, newdir might
4563 point at constant storage, so make it a const pointer.
4564 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
4565 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
4567 (Fset_file_times, Finsert_file_contents, auto_save_error):
4568 Rename locals to avoid shadowing.
4570 * minibuf.c (choose_minibuf_frame_1): Now static.
4571 (Ftry_completion, Fall_completions): Rename or remove locals
4574 * marker.c (bytepos_to_charpos): Remove; unused.
4576 * lisp.h (verify_bytepos, count_markers): New decls,
4577 so that gcc does not warn that these functions aren't declared.
4579 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
4580 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
4581 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
4582 (copy_text): Remove unused local var.
4584 * filelock.c (within_one_second): Now static.
4585 (lock_file_1): Rename local to avoid shadowing.
4587 * buffer.c (fix_overlays_before): Mark locals as initialized.
4588 (fix_start_end_in_overlays): Likewise. This function should be
4589 simplified by using pointers-to-pointers, but that's a different
4591 (switch_to_buffer_1): Now static.
4592 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
4593 (report_overlay_modification): Rename locals to avoid shadowing.
4595 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
4596 Fix pointer signedness issue.
4597 (sys_subshell): Mark local as volatile if checking for lint,
4598 to suppress a gcc -Wclobbered warning that does not seem to be right.
4599 (MAXPATHLEN): Define only if needed.
4601 * process.c (serial_open, serial_configure): Move decls from here ...
4602 * systty.h: ... to here, so that they can be checked.
4604 * fns.c (get_random, seed_random): Move extern decls from here ...
4605 * lisp.h: ... to here, so that they can be checked.
4607 * sysdep.c (reset_io): Now static.
4608 (wait_for_termination_signal): Remove; unused.
4610 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

4613 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
4614 (DENSE_TABLE_SIZE): Remove; unused.
4615 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
4616 (describe_map_tree):
4617 Rename locals to avoid shadowing.
4619 * keyboard.c: Declare functions static if they are not used elsewhere.
4620 (echo_char, echo_dash, cmd_error, top_level_2):
4621 (poll_for_input, handle_async_input): Now static.
4622 (read_char, kbd_buffer_get_event, make_lispy_position):
4623 (make_lispy_event, make_lispy_movement, apply_modifiers):
4624 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
4625 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
4626 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
4627 (read_key_sequence, read_char): Mark locals as initialized.
4628 (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.

4631 (mark_kboards): Move decl here ...
4632 * alloc.c (mark_kboards): ... from here.
4634 * lisp.h (force_auto_save_soon): New decl.

4637 (DEFINE_DUMMY_FUNCTION): New macro.
4638 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
4640 (main): Add casts to avoid warnings
4641 if GCC considers string literals to be constants.
4643 * lisp.h (fatal_error_signal): Add decl, since it's exported.
