3 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
4 * category.c (hash_get_category_set):
6 * charset.c (Fdefine_charset_internal):
7 * charset.h (struct charset.hash_index):
8 * composite.c (get_composition_id, gstring_lookup_cache)
9 (composition_gstring_put_cache):
10 * composite.h (struct composition.hash_index):
11 * dispextern.h (struct image.hash):
12 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
13 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
14 (hashfn_equal, hashfn_user_defined, make_hash_table)
15 (maybe_resize_hash_table, hash_lookup, hash_put)
16 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
17 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
18 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19 * image.c (make_image, search_image_cache, lookup_image)
20 (xpm_put_color_table_h):
21 * lisp.h (struct Lisp_Hash_Table):
22 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
23 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
24 for hashes and hash indexes, instead of 'unsigned' and 'int'.
25 * alloc.c (allocate_vectorlike): Check for overflow in vector size
27 * ccl.c (ccl_driver): Check for overflow when converting EMACS_INT
29 * fns.c, image.c: Remove unnecessary static decls that would otherwise
30 need to be updated by these changes.
31 * fns.c (make_hash_table, maybe_resize_hash_table): Check for integer
32 overflow with large hash tables.
33 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
34 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
35 (SXHASH_REDUCE): New macro.
36 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
37 Use it instead of discarding useful hash info with large hash values.
38 (sxhash_float): New function.
39 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
40 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
41 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK): Rewrite
42 to use FIXNUM_BITS, as this simplifies things.
43 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
44 Adjust signatures to match updated version of code.
45 (consing_since_gc): Now EMACS_INT, since a single hash table can
46 use more than INT_MAX bytes.
48 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
50 Use 'inline', not 'INLINE'.
51 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
52 * alloc.c, fontset.c (INLINE): Remove.
53 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
54 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
55 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
56 * gmalloc.c (register_heapinfo): Use inline unconditionally.
57 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
59 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
61 Make it possible to run ./temacs.
63 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
64 syms_of_callproc does the same thing. Remove test for
65 "initialized", do it in the caller.
66 * emacs.c (main): Avoid calling set_initial_environment when dumping.
68 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
70 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
71 (read_minibuf): Use get_minibuffer.
72 (syms_of_minibuf): Use DEFSYM.
74 * data.c (Qbuffer): Don't make it static.
75 (syms_of_data): Use DEFSYM.
77 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
79 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
80 (CCL_CODE_MIN): New macro.
82 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
84 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
86 * eval.c (Qdebug): Now static.
87 * lisp.h (Qdebug): Remove decl. This reverts a part of the
88 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
89 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
91 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
93 * image.c: Various fixes to ImageMagick code comments.
94 (Fimagemagick_types): Doc fix.
96 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
98 Minor fixes prompted by GCC 4.6.0 warnings.
100 * xselect.c (converted_selections, conversion_fail_tag): Now static.
102 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
103 (x_clipboard_manager_save_all): Move extern decl to ...
104 * xterm.h: ... here, so that it can be checked for consistency.
106 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
108 * xselect.c (x_clipboard_manager_save_frame)
109 (x_clipboard_manager_save_all): New functions.
110 (Fx_clipboard_manager_save): Lisp function deleted.
112 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
113 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
115 * xterm.h: Update prototype.
117 2011-05-28 William Xu <william.xwl@gmail.com>
119 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
122 2011-05-28 Jim Meyering <meyering@redhat.com>
124 Avoid a sign-extension bug in crypto_hash_function.
125 * fns.c (to_uchar): Define.
126 (crypto_hash_function): Use it to convert some newly-signed
127 variables to unsigned, to avoid sign-extension bugs. For example,
128 without this change, (md5 "truc") would evaluate to
129 45723a2aff78ff4fff7fff1114760e62 rather than the expected
130 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
131 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
133 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
135 Integer overflow fixes.
137 * dbusbind.c: Serial number integer overflow fixes.
138 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
139 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
140 to hold a serial number that is too large for a fixnum.
141 (Fdbus_method_return_internal, Fdbus_method_error_internal):
142 Check for serial numbers out of range. Decode any serial number
143 that was so large that it became a float. (Bug#8722)
145 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
146 (Fdbus_call_method, Fdbus_call_method_asynchronously):
147 Use XFASTINT rather than XUINT when numbers are nonnegative.
148 (xd_append_arg, Fdbus_method_return_internal):
149 (Fdbus_method_error_internal): Likewise. Also, for unsigned
150 arguments, check that Lisp number is nonnegative, rather than
151 silently wrapping negative numbers around. (Bug#8722)
152 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
155 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
157 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
159 ccl: add integer overflow checks
160 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
161 (IN_INT_RANGE): New macros.
162 (ccl_driver): Use them to check for integer overflow when
163 decoding a CCL program. Many of the new checks are whether XINT (x)
164 fits in int; it doesn't always, on 64-bit hosts. The new version
165 doesn't catch all possible integer overflows, but it's an
166 improvement. (Bug#8719)
168 * alloc.c (make_event_array): Use XINT, not XUINT.
169 There's no need for unsigned here.
171 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
172 This follows up to the 2011-05-06 change that substituted uintptr_t
173 for EMACS_INT. This case wasn't caught back then.
175 Rework Fformat to avoid integer overflow issues.
176 * editfns.c: Include <float.h> unconditionally, as it's everywhere
177 now (part of C89). Include <verify.h>.
178 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
179 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
180 (Fformat): Avoid the prepass trying to compute sizes; it was only
181 approximate and thus did not catch overflow reliably. Instead, walk
182 through the format just once, formatting and computing sizes as we go,
183 checking for integer overflow at every step, and allocating a larger
184 buffer as needed. Keep track separately whether the format is
185 multibyte. Keep only the most-recently calculated precision, rather
186 than them all. Record whether each argument has been converted to
187 string. Use EMACS_INT, not int, for byte and char and arg counts.
188 Support field widths and precisions larger than INT_MAX. Avoid
189 sprintf's undefined behavior with conversion specifications such as %#d
190 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
191 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
192 formatting out-of-range floating point numbers with int
195 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
197 * data.c: Avoid integer truncation in expressions involving floats.
198 * data.c: Include <intprops.h>.
199 (arith_driver): When there's an integer overflow in an expression
200 involving floating point, convert the integers to floating point
201 so that the resulting value does not suffer from catastrophic
202 integer truncation. For example, on a 64-bit host (* 4
203 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
204 Do not rely on undefined behavior after integer overflow.
206 merge count_size_as_multibyte, parse_str_to_multibyte
207 * character.c, character.h (count_size_as_multibyte):
208 Renamed from parse_str_to_multibyte; all uses changed.
209 Check for integer overflow.
210 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
211 since it's now a duplicate of the other. This is more of
212 a character than a buffer op, so better that it's in character.c.
213 * fns.c, print.c: Adjust to above changes.
215 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
217 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
219 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
221 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
222 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
223 (x_clipboard_manager_save): Now static.
224 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
226 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
227 (crypto_hash_function): Now static.
228 Fix pointer signedness problems. Avoid unnecessary initializations.
230 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
232 * termhooks.h (Vselection_alist): Make it terminal-local.
234 * terminal.c (create_terminal): Initialize it.
236 * xselect.c: Support for clipboard managers.
237 (Vselection_alist): Move to termhooks.h as terminal-local var.
238 (LOCAL_SELECTION): New macro.
239 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
240 (symbol_to_x_atom): Remove gratuitous arg.
241 (x_handle_selection_request, lisp_data_to_selection_data)
242 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
243 (x_own_selection, x_get_local_selection, x_convert_selection):
244 New arg, specifying work frame. Use terminal-local Vselection_alist.
245 (some_frame_on_display): Delete unused function.
246 (Fx_own_selection_internal, Fx_get_selection_internal)
247 (Fx_disown_selection_internal, Fx_selection_owner_p)
248 (Fx_selection_exists_p): New optional frame arg.
249 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
250 (x_handle_selection_clear): Don't treat other terminals with the
251 same keyboard specially. Use the terminal-local Vselection_alist.
252 (x_clear_frame_selections): Use Frun_hook_with_args.
254 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
256 * xterm.h: Add support for those atoms.
258 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
260 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
261 (converted_selections, conversion_fail_tag): New global variables.
262 (x_selection_request_lisp_error): Free the above.
263 (x_get_local_selection): Remove unnecessary code.
264 (x_reply_selection_request): Args changed; handle arbitrary array
265 of converted selections stored in converted_selections.
266 Separate the XChangeProperty and SelectionNotify steps.
267 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
268 (x_convert_selection): New function.
269 (x_handle_selection_event): Simplify.
270 (x_get_foreign_selection): Don't ignore incoming requests while
271 waiting for an answer; this will fail when we implement
272 SAVE_TARGETS, and seems unnecessary anyway.
273 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
274 (Vx_sent_selection_functions): Doc fix.
276 2011-05-26 Leo Liu <sdl.web@gmail.com>
278 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
280 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
282 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
284 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
285 for fringe update if it has periodic bitmap.
286 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
287 and fringe_bitmap_periodic_p.
289 * fringe.c (get_fringe_bitmap_data): New function.
290 (draw_fringe_bitmap_1, update_window_fringes): Use it.
291 (update_window_fringes): Record periodicity of fringe bitmap in glyph
292 row. Mark glyph row for fringe update if periodicity changed.
294 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
295 for fringe update unless it has periodic bitmap.
297 2011-05-25 Kenichi Handa <handa@m17n.org>
299 * xdisp.c (get_next_display_element): Set correct it->face_id for
300 a static composition.
302 2011-05-24 Leo Liu <sdl.web@gmail.com>
305 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
307 * fns.c (crypto_hash_function, Fsha1): New function.
308 (Fmd5): Use crypto_hash_function.
309 (syms_of_fns): Add Ssha1.
311 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
313 * gnutls.c: Remove unused macros.
314 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
315 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
316 Remove macros that are defined and never used.
317 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
319 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
321 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
322 (Fx_get_selection_internal): Minor cleanup.
323 (Fx_own_selection_internal): Rename arguments for consistency with
326 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
328 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
330 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
332 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
334 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
336 * dispnew.c (scrolling_window): Don't exclude the case that the
337 last enabled row in the desired matrix touches the bottom boundary.
339 2011-05-21 Glenn Morris <rgm@gnu.org>
341 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
342 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
343 and add some more files.
345 2011-05-20 Eli Zaretskii <eliz@gnu.org>
347 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
348 report_file_error introduced by the change from 2011-05-07.
350 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
352 * systime.h (Time): Define only if emacs is defined.
353 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
354 where the include path doesn't have X11/X.h by default. See
355 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
357 2011-05-20 Kenichi Handa <handa@m17n.org>
359 * composite.c (find_automatic_composition): Fix previous change.
361 2011-05-20 Glenn Morris <rgm@gnu.org>
363 * lisp.mk: New file, split from Makefile.in.
364 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
366 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
368 2011-05-19 Glenn Morris <rgm@gnu.org>
370 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
371 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
372 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
373 (lisp): Set the order to that of loadup.el.
374 (shortlisp): Make it a copy of $lisp.
375 (SOME_MACHINE_LISP): Remove.
376 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
377 Use just $shortlisp, not $SOME_MACHINE_LISP too.
379 2011-05-18 Kenichi Handa <handa@m17n.org>
381 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
382 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
383 (find_automatic_composition): Mostly rewrite for efficiency.
385 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
387 * makefile.w32-in: Update dependencies.
389 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
391 * menu.c: Include limits.h (fixes the MS-Windows build broken by
394 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
396 Fix some integer overflow issues, such as string length overflow.
398 * insdel.c (count_size_as_multibyte): Check for string overflow.
400 * character.c (lisp_string_width): Check for string overflow.
401 Use EMACS_INT, not int, for string indexes and lengths; in
402 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
403 the resulting string length overflows an EMACS_INT; instead,
404 report a string overflow if no precision given. When checking for
405 precision exhaustion, use a check that cannot possibly have
406 integer overflow. (Bug#8675)
407 * character.h (lisp_string_width): Adjust to new signature.
409 * alloc.c (string_overflow): New function.
410 (Fmake_string): Use it. This doesn't change behavior, but saves
411 a few bytes and will simplify future changes.
412 * character.c (string_escape_byte8): Likewise.
413 * lisp.h (string_overflow): New decl.
415 Fixups, following up to the user-interface timestamp change.
416 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
417 for UI timestamps, instead of unsigned long.
418 * msdos.c (mouse_get_pos): Likewise.
419 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
420 * w32gui.h (Time): Define by including "systime.h" rather than by
421 declaring it ourselves. (Bug#8664)
423 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
424 * image.c (clear_image_cache): Likewise.
426 * term.c (term_mouse_position): Don't assume time_t wraparound.
428 Be more systematic about user-interface timestamps.
429 Before, the code sometimes used 'Time', sometimes 'unsigned long',
430 and sometimes 'EMACS_UINT', to represent these timestamps.
431 This change causes it to use 'Time' uniformly, as that's what X uses.
432 This makes the code easier to follow, and makes it easier to catch
433 integer overflow bugs such as Bug#8664.
434 * frame.c (Fmouse_position, Fmouse_pixel_position):
435 Use Time, not unsigned long, for user-interface timestamps.
436 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
437 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
438 * keyboard.h (last_event_timestamp): Likewise.
439 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
440 * menu.h (xmenu_show): Likewise.
441 * term.c (term_mouse_position): Likewise.
442 * termhooks.h (struct input_event.timestamp): Likewise.
443 (struct terminal.mouse_position_hook): Likewise.
444 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
445 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
446 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
447 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
449 * menu.h, termhooks.h: Include "systime.h", for Time.
451 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
452 Don't assume that the difference between two unsigned long values
453 can fit into an integer. At this point, we know button_down_time
454 <= event->timestamp, so the difference must be nonnegative, so
455 there's no need to cast the result if double-click-time is
456 nonnegative, as it should be; check that it's nonnegative, just in
457 case. This bug is triggered when events are more than 2**31 ms
458 apart (about 25 days). (Bug#8664)
460 * xselect.c (last_event_timestamp): Remove duplicate decl.
461 (x_own_selection): Remove needless cast to unsigned long.
463 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
464 that always fit in int. Use a sentinel instead of a counter, to
465 avoid a temp and to allay GCC's concerns about possible int overflow.
466 * frame.h (struct frame): Use int for menu_bar_items_used
467 instead of EMACS_INT, since it always fits in int.
469 * menu.c (grow_menu_items): Check for int overflow.
471 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
473 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
474 Before, the code was not consistent. These values cannot exceed
475 2**31 - 1 so there's no need to make them unsigned.
476 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
477 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
478 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
480 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
482 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
483 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
484 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
485 presumably because the widths might not match.
487 * window.c (size_window): Avoid needless test at loop start.
489 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
491 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
493 2011-05-12 Drew Adams <drew.adams@oracle.com>
495 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
497 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
499 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
500 `width' to `bar_area_x' and `bar_area_width', respectively.
501 (x_scroll_run): Take account of fringe background extension.
503 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
504 Rename local vars `left' and `width' to `bar_area_x' and
505 `bar_area_width', respectively.
506 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
507 background extension.
509 2011-05-10 Jim Meyering <meyering@redhat.com>
511 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
513 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
515 * image.c (Finit_image_library): Return t for built-in image types,
516 like pbm and xbm. (Bug#8640)
518 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
520 * w32menu.c (set_frame_menubar): Fix submenu allocation.
522 2011-05-07 Eli Zaretskii <eliz@gnu.org>
524 * w32console.c (Fset_screen_color): Doc fix.
525 (Fget_screen_color): New function.
526 (syms_of_ntterm): Defsubr it.
528 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
529 unlink the temporary file if Fcall_process didn't create it in the
531 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
532 child process will be redirected to a file specified with `:file'.
533 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
534 cue to call_process_cleanup not to close that handle.
536 2011-05-07 Ben Key <bkey76@gmail.com>
538 * makefile.w32-in: The bootstrap-temacs rule now makes use of
539 one of two shell specific rules, either bootstrap-temacs-CMD or
540 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
541 to the previous implementation of the bootstrap-temacs rule.
542 The bootstrap-temacs-CMD rule is similar to the previous
543 implementation of the bootstrap-temacs rule except that it
544 makes use of the ESC_CFLAGS variable instead of the CFLAGS
547 These changes, along with some changes to nt/configure.bat,
548 nt/gmake.defs, and nt/nmake.defs, are required to extend my
549 earlier fix to add support for --cflags and --ldflags options
550 that include quotes so that it works whether make uses cmd or
553 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
555 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
556 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
558 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
559 a string. Handle both cases.
560 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
561 (Fdbus_register_method): Use Qinvalid_function.
563 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
565 * makefile.w32-in: Update dependencies.
566 (LISP_H): Add inttypes.h and stdin.h.
567 (PROCESS_H): Add unistd.h.
569 2011-05-06 Eli Zaretskii <eliz@gnu.org>
571 * lread.c: Include limits.h (fixes the MS-Windows build broken by
572 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
574 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
576 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
578 * term.c (vfatal): Remove stray call to va_end.
579 It's not needed and the C Standard doesn't allow it here anyway.
581 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
582 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
584 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
587 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
589 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
591 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
593 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
595 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
597 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
598 * charset.c (Fdefine_charset_internal): Don't initialize
599 charset.code_space[15]. The value was garbage, on hosts with
600 32-bit int (Bug#8600).
602 * lread.c (read_integer): Be more consistent with string-to-number.
603 Use string_to_number to do the actual conversion; this avoids
604 rounding errors and fixes some other screwups. Without this fix,
605 for example, #x1fffffffffffffff was misread as -2305843009213693952.
606 (digit_to_number): Move earlier, for benefit of read_integer.
607 Return -1 if the digit is out of range for the base, -2 if it is
608 not a digit in any supported base. (Bug#8602)
610 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
612 * dispnew.c (scrolling_window): Return 1 if we scrolled,
613 to match comment at start of function. This also removes a
614 GCC warning about overflow in a 32+64-bit port.
616 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
618 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
619 Reported by Stefan Monnier in
620 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
621 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
622 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
624 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
625 (EMACS_UINTPTR): Likewise, with uintptr_t.
627 * lisp.h: Prefer 64-bit EMACS_INT if available.
628 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
629 on 32-bit hosts that have 64-bit int, so that they can access
631 However, temporarily disable this change unless the temporary
632 symbol WIDE_EMACS_INT is defined.
634 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
636 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
637 This removes an assumption that EMACS_INT and long are the same
638 width as pointers. The assumption is true for Emacs porting targets
639 now, but we want to make other targets possible.
640 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
641 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
642 In the rest of the code, change types of integers that hold casted
643 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
644 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
645 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
646 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
647 No need to cast type when ORing.
648 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
649 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
650 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
651 assume EMACS_INT is the same width as char *.
652 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
653 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
654 Remove no-longer-needed casts.
655 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
656 (xg_tool_bar_help_callback, xg_make_tool_item):
657 Use EMACS_INTPTR to hold an integer
658 that will be cast to void *; this can avoid a GCC warning
659 if EMACS_INT is not the same width as void *.
660 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
661 * xdisp.c (display_echo_area_1, resize_mini_window_1):
662 (current_message_1, set_message_1):
663 Use a local to convert to proper width without a cast.
664 * xmenu.c (dialog_selection_callback): Likewise.
666 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
667 Also, don't assume VALBITS / RAND_BITS is less than 5,
668 and don't rely on undefined behavior when shifting a 1 left into
670 * lisp.h (get_random): Change signature to match.
672 * lread.c (hash_string): Use size_t, not int, for hash computation.
673 Normally we prefer signed values; but hashing is special, because
674 it's better to use unsigned division on hash table sizes so that
675 the remainder is nonnegative. Also, size_t is the natural width
676 for hashing into memory. The previous code used 'int', which doesn't
677 retain enough info to hash well into very large tables.
678 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
680 * dbusbind.c: Don't possibly lose pointer info when converting.
681 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
682 Use XPNTR rather than XHASH, so that the high-order bits of
683 the pointer aren't lost when converting through void *.
685 * eval.c (Fautoload): Don't double-shift a pointer.
687 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
689 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
691 * gnutls.c (DEF_GNUTLS_FN):
692 * image.c (DEF_IMGLIB_FN): Make function pointers static.
694 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
696 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
699 2011-05-05 Eli Zaretskii <eliz@gnu.org>
701 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
702 New version that can reserve upto 2GB of heap space.
704 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
706 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
708 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
710 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
711 `gnutls_certificate_set_x509_key_file'.
713 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
715 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
718 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
720 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
721 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
722 Remove unused parameter `fildes'.
723 * process.c (read_process_output, send_process): Don't pass it.
725 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
727 Fix previous change: the library cache is defined in w32.c.
728 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
729 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
731 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
733 Implement dynamic loading of GnuTLS on Windows.
735 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
736 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
737 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
740 * gnutls.c (Qgnutls_dll): Define.
741 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
742 (gnutls_*): Declare function pointers.
743 (init_gnutls_functions): New function to initialize function pointers.
744 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
745 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
746 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
747 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
748 (emacs_gnutls_write, emacs_gnutls_read)
749 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
750 (Fgnutls_available_p): New function.
751 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
752 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
753 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
755 * image.c: Include w32.h.
756 (Vimage_type_cache): Delete.
757 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
758 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
759 (w32_delayed_load): Move to w32.c.
761 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
763 * w32.c (QCloaded_from, Vlibrary_cache): Define.
764 (w32_delayed_load): Move from image.c. When loading a library, record
765 its filename in the :loaded-from property of the library id.
766 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
767 Initialize and staticpro them.
768 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
770 * process.c: Include lisp.h before w32.h, not after.
771 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
772 instead of gnutls_record_check_pending.
774 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
776 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
778 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
779 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
782 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
784 * xterm.c (x_set_frame_alpha): Do not set property on anything
785 else than FRAME_X_OUTER_WINDOW (Bug#8608).
787 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
789 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
791 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
793 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
794 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

809 Move after wait_for_termination_1.
811 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
813 * sysdep.c (interruptible_wait_for_termination): New function
814 which is like wait_for_termination, but allows keyboard
817 * callproc.c (Fcall_process): Add (:file "file") as an option for
819 (Fcall_process_region): Ditto.
821 2011-04-30 Eli Zaretskii <eliz@gnu.org>
823 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
824 rather than `XVECTOR (FOO)->size'.
826 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
827 inttypes.h, as a gnulib replacement is used if it not available in
830 2011-04-21 Eli Zaretskii <eliz@gnu.org>
832 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
833 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
834 of MOST_POSITIVE_FIXNUM. (Bug#8528)
836 * coding.c (coding_alloc_by_realloc): Error out if destination
837 will grow beyond MOST_POSITIVE_FIXNUM.
838 (decode_coding_emacs_mule): Abort if there isn't enough place in
839 charbuf for the composition carryover bytes. Reserve an extra
840 space for up to 2 characters produced in a loop.
841 (decode_coding_iso_2022): Abort if there isn't enough place in
842 charbuf for the composition carryover bytes.
844 2011-04-21 Eli Zaretskii <eliz@gnu.org>
846 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
847 aborting when %lld or %lll format is passed.
848 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
849 %llo or %llx format is passed. (Bug#8545)
851 * window.c (window_scroll_line_based): Use a marker instead of
852 simple variables to record original value of point. (Bug#7952)
854 * doprnt.c (doprnt): Fix the case where a multibyte sequence
855 produced by %s or %c overflows available buffer space. (Bug#8545)
857 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
859 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

872 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
874 2011-04-28 Eli Zaretskii <eliz@gnu.org>
876 * doprnt.c (doprnt): Don't return value smaller than the buffer
877 size if the message was truncated. (Bug#8545).
879 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
881 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
882 (Fx_window_property): #if-0 the whole functions, not just the bodies.
884 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
886 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
888 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
890 * makefile.w32-in: Update dependencies.
892 2011-04-27 Eli Zaretskii <eliz@gnu.org>
894 Improve `doprnt' and its usage. (Bug#8545)
895 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
896 `format_end'. Remove support for %l as a conversion specifier.
897 Don't use xrealloc. Improve diagnostics when the %l size modifier
898 is used. Update the commentary.
900 * eval.c (verror): Simplify calculation of size_t.
902 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
905 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
907 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
910 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
912 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
913 This makes this file independent of the recent pseudovector change.
915 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
917 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
919 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
920 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
922 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
924 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
925 GCC 4.6.0 optimizes based on type-based alias analysis.
926 For example, if b is of type struct buffer * and v of type struct
927 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
928 != &v->size, and therefore "v->size = 1; b->size = 2; return
929 v->size;" must therefore return 1. This assumption is incorrect
930 for Emacs, since it type-puns struct Lisp_Vector * with many other
931 types. To fix this problem, this patch adds a new type struct
932 vectorlike_header that documents the constraints on layout of vectors
933 and pseudovectors, and helps optimizing compilers not get fooled
934 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
935 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
936 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
938 (XSETPVECTYPE): Rewrite in terms of new macro.
939 (XSETPVECTYPESIZE): New macro, specifying both type and size.
940 This is a bit clearer, and further avoids the possibility of
941 undesirable aliasing.
942 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
943 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
944 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
945 since Lisp_Subr is a special case (no "next" field).
946 (ASIZE): Now uses header.size rather than size.
947 All previous uses of XVECTOR (foo)->size replaced to use this macro,
948 to avoid the hassle of writing XVECTOR (foo)->header.size.
949 (struct vectorlike_header): New type.
950 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
951 object, to help avoid aliasing.
952 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
953 (SUBRP): Likewise, since Lisp_Subr is a special case.
954 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
955 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
956 (struct Lisp_Hash_Table): Combine first two members into a single
957 struct vectorlike_header member. All uses of "size" and "next" members
958 changed to be "header.size" and "header.next".
959 * buffer.h (struct buffer): Likewise.
960 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
961 * frame.h (struct frame): Likewise.
962 * process.h (struct Lisp_Process): Likewise.
963 * termhooks.h (struct terminal): Likewise.
964 * window.c (struct save_window_data, struct saved_window): Likewise.
965 * window.h (struct window): Likewise.
966 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
967 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
968 * buffer.c (init_buffer_once): Likewise.
969 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
971 * process.c (Fformat_network_address): Use local var for size,
974 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
976 Make the Lisp reader and string-to-float more consistent (Bug#8525)
977 * data.c (atof): Remove decl; no longer used or needed.
978 (digit_to_number): Move to lread.c.
979 (Fstring_to_number): Use new string_to_number function, to be
980 consistent with how the Lisp reader treats infinities and NaNs.
981 Do not assume that floating-point numbers represent EMACS_INT
982 without losing information; this is not true on most 64-bit hosts.
983 Avoid double-rounding errors, by insisting on integers when
984 parsing non-base-10 numbers, as the documentation specifies.
985 * lisp.h (string_to_number): New decl, replacing ...
986 (isfloat_string): Remove.
987 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
988 (read1): Do not accept +. and -. as integers; this
989 appears to have been a coding error. Similarly, do not accept
990 strings like +-1e0 as floating point numbers. Do not report
991 overflow for integer overflows unless the base is not 10 which
992 means we have no simple and reliable way to continue.
993 Break out the floating-point parsing into a new
994 function string_to_number, so that Fstring_to_number parses
995 floating point numbers consistently with the Lisp reader.
996 (digit_to_number): Move here from data.c. Make it static inline.
997 (E_CHAR, EXP_INT): Remove, replacing with ...
998 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
999 (string_to_number): New function, replacing isfloat_string.
1000 This function checks for valid syntax and produces the resulting
1001 Lisp float number too. Rework it so that string-to-number
1002 no longer mishandles examples like "1.0e+". Use strtoumax,
1003 so that overflow for non-base-10 numbers is reported only when
1004 there's no portable and simple way to convert to floating point.
1006 * textprop.c (set_text_properties_1): Rewrite for clarity,
1007 and to avoid GCC warning about integer overflow.
1009 * intervals.h (struct interval): Use EMACS_INT for members
1010 where EMACS_UINT might cause problems. See
1011 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
1012 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
1013 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
1015 (offset_intervals): Tell GCC not to worry about length overflow
1016 when negating a negative length.
1018 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
1019 (overrun_check_free): Likewise.
1021 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
1022 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
1025 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1026 (gnutls_make_error): Rename local to avoid shadowing.
1027 (gnutls_emacs_global_deinit): ifdef out; not used.
1028 (Fgnutls_boot): Use const for pointer to readonly storage.
1029 Comment out unused local. Fix pointer signedness problems.
1031 * lread.c (openp): Don't stuff size_t into an 'int'.
1032 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
1033 about possible signed overflow.
1035 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
1036 (GDK_KEY_g): Don't define if already defined.
1037 (xg_prepare_tooltip): Avoid pointer signedness problem.
1038 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
1040 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
1041 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
1043 * xfns.c (Fx_window_property): Simplify a bit,
1044 to make a bit faster and to avoid GCC 4.6.0 warning.
1045 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
1047 * fns.c (internal_equal): Don't assume size_t fits in int.
1049 * alloc.c (compact_small_strings): Tighten assertion a little.
1051 Replace pEd with more-general pI, and fix some printf arg casts.
1052 * lisp.h (pI): New macro, generalizing old pEd macro to other
1053 conversion specifiers. For example, use "...%"pI"d..." rather
1054 than "...%"pEd"...".
1055 (pEd): Remove. All uses replaced with similar uses of pI.
1056 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
1057 * alloc.c (check_pure_size): Don't overflow by converting size to int.
1058 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
1059 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
1060 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
1061 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
1062 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
1064 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
1065 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
1066 * print.c (safe_debug_print, print_object): Likewise.
1067 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
1069 Use pI instead of if-then-else-abort. Use %p to avoid casts,
1070 avoiding the 0 flag, which is not portable.
1071 * process.c (Fmake_network_process): Use pI to avoid cast.
1072 * region-cache.c (pp_cache): Likewise.
1073 * xdisp.c (decode_mode_spec): Likewise.
1074 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
1075 behavior on 64-bit hosts with printf arg.
1076 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
1077 (x_stop_queuing_selection_requests): Likewise.
1078 (x_get_window_property): Don't truncate byte count to an 'int'
1081 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
1082 here, since it parses constructs like leading '-' and spaces,
1083 which are not wanted; and it overflows with large numbers.
1084 Instead, simply match F[0-9]+, which is what is wanted anyway.
1086 * alloc.c: Remove unportable assumptions about struct layout.
1087 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
1088 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
1089 (allocate_vectorlike, make_pure_vector): Use the new macros,
1090 plus offsetof, to remove unportable assumptions about struct layout.
1091 These assumptions hold on all porting targets that I know of, but
1092 they are not guaranteed, they're easy to remove, and removing them
1093 makes further changes easier.
1095 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
1096 This doesn't fix a bug but makes the code clearer.
1097 (string_overrun_cookie): Now const. Use initializers that
1098 don't formally overflow signed char, to avoid warnings.
1099 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
1100 can cause Emacs to crash when string overrun checking is enabled.
1101 (allocate_buffer): Don't assume sizeof (struct buffer) is a
1102 multiple of sizeof (EMACS_INT); it need not be, if
1103 alignof(EMACS_INT) < sizeof (EMACS_INT).
1104 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
1106 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
1108 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.

1127 (check_string_free_list): Convert to standard C.
1129 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
1131 * w32.c (emacs_gnutls_push): Fix typo.
1133 2011-04-25 Eli Zaretskii <eliz@gnu.org>
1135 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
1136 "cast to pointer from integer of different size".
1138 Improve doprnt and its use in verror. (Bug#8545)
1139 * doprnt.c (doprnt): Document the set of format control sequences
1140 supported by the function. Use SAFE_ALLOCA instead of always
1143 * eval.c (verror): Don't limit the buffer size at size_max-1, that
1144 is one byte too soon. Don't use xrealloc; instead xfree and
1147 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
1149 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

1153 gnutls_global_initialized. Added internals for the
1154 :verify-hostname-error, :verify-error, and :verify-flags
1155 parameters of `gnutls-boot' and documented those parameters in the
1156 docstring. Start callback support.
1157 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
1158 unless a fatal error occured. Call gnutls_alert_send_appropriate
1159 on error. Return error code.
1160 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
1161 (emacs_gnutls_read): Likewise.
1162 (Fgnutls_boot): Return handshake error code.

1231 * doprnt.c: Include limits.h.
1232 (SIZE_MAX): New macro.
1233 (doprnt): Return a size_t value. 2nd arg is now size_t.
1234 Many local variables are now size_t instead of int or unsigned.
1235 Improve overflow protection. Support `l' modifier for integer
1236 conversions. Support %l conversion. Don't assume an EMACS_INT
1237 argument for integer conversions and for %c.
1239 * lisp.h (doprnt): Restore prototype.
1241 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
1244 * Makefile.in (base_obj): Add back doprnt.o.
1246 * deps.mk (doprnt.o): Add back prerequisites.
1247 (callint.o): Depend on character.h.
1249 * eval.c (internal_lisp_condition_case): Include the handler
1250 representation in the error message.
1251 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
1252 when breaking from the loop.
1254 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
1256 * callint.c (Fcall_interactively): When displaying error message
1257 about invalid control letter, pass the character's codepoint, not
1258 a pointer to its multibyte form. Improve display of the character
1259 in octal and display also its hex code.
1261 * character.c (char_string): Use %x to display the (unsigned)
1262 codepoint of an invalid character, to avoid displaying a bogus
1265 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
1266 `error', not SYMBOL_NAME itself.
1268 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
1269 character arguments to `error'.
1271 * charset.c (check_iso_charset_parameter): Fix incorrect argument
1272 to `error' in error message about FINAL_CHAR argument. Make sure
1273 FINAL_CHAR is a character, and use %c when it is passed as
1274 argument to `error'.
1276 2011-04-23 Eli Zaretskii <eliz@gnu.org>
1278 * s/ms-w32.h (localtime): Redirect to sys_localtime.

1355 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
1356 so that we aren't warned about unused symbols.

1367 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
1368 (x_dispatch_event): Declare static if USE_GTK, and
1369 define if USE_GTK || USE_X_TOOLKIT.
1370 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
1371 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
1372 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
1373 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
1375 * xmenu.c (menu_help_callback): Pointer type fixes.
1376 Use const pointers when pointing at readonly data. Avoid pointer

1379 (update_frame_menubar): Remove unused decl.
1381 * xfns.c (Fx_hide_tip): Move locals to avoid shadowing.
1383 * menu.c (push_submenu_start, push_submenu_end): Do not define unless

1387 * keyboard.c (make_lispy_event): Remove unused local var.
1389 * frame.c, frame.h (x_get_resource_string): Bring this back, but
1390 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
1392 * bitmaps: Change bitmaps from unsigned char back to the X11
1393 compatible char. Avoid the old compiler warnings about
1394 out-of-range initializers by using, for example, '\xab' rather
1397 * xgselect.c (xgselect_initialize): Check vs interface
1398 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
1400 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.
1402 * xterm.c (x_create_toolkit_scroll_bar): Use const * for pointers

1463 * nsfont.m: Fixed bugs in ns_get_family and
1464 ns_descriptor_to_entity that were caused by using free to
1465 deallocate memory blocks that were allocated by xmalloc (via
1466 xstrdup). This caused Emacs to crash when compiled with
1467 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
1468 --enable-checking=xmallocoverrun). xfree is now used to
1469 deallocate these memory blocks.

1486 (emacs_read, emacs_write): Use it.
1487 * process.c (send_process): Adjust to the new signatures of
1488 emacs_write and emacs_gnutls_write. Do not attempt to store

1866 * xmenu.c, xselect.c:
1867 Declare Q* vars static if they are not used in other modules.
1868 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
1869 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
1870 Remove decls of unexported vars.
1871 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
1873 * lisp.h (DEFINE_FUNC): Make sname 'static'.
1875 Make Emacs functions such as Fatom 'static' by default.
1876 This makes it easier for human readers (and static analyzers)
1877 to see whether these functions can be called from other modules.
1878 DEFUN now defines a static function. To make the function external
1879 so that it can be used in other C modules, use the new macro DEFUE.
1880 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
1881 (Finit_image_library):
1882 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
1883 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
1884 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
1885 Remove decls, since these functions are now static.
1886 (Funintern, Fget_internal_run_time): New decls, since these functions
1887 were already external.
1889 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
1890 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

1896 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
1897 Mark functions with DEFUE instead of DEFUN,
1898 if they are used in other modules.
1899 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
1900 decls for now-static functions.
1901 * buffer.h (Fdelete_overlay): Remove decl.

1914 (Fremove_list_of_text_properties): Remove decls.
1915 * keyboard.c (Fthis_command_keys): Remove decl.
1916 (Fcommand_execute): New forward static decl.
1917 * keymap.c (Flookup_key): New forward static decl.
1918 (Fcopy_keymap): Now static.
1919 * keymap.h (Flookup_key): Remove decl.

1932 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
1934 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
1937 2011-04-13 Eli Zaretskii <eliz@gnu.org>

1940 when at ZV. (Bug#8487)
1942 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
1944 * charset.c (Fclear_charset_maps): Use xfree instead of free.
1946 * keyboard.c (parse_tool_bar_item): Likewise.
1947 * sound.c (sound_cleanup, alsa_close): Likewise.
1948 * termcap.c (tgetent): Likewise.
1949 * xfns.c (x_default_font_parameter): Likewise.
1950 * xsettings.c (read_and_apply_settings): Likewise.
1952 * alloc.c (overrun_check_malloc, overrun_check_realloc)
1953 (overrun_check_free): Protoize.
1955 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
1957 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
1958 since callers should never pass a negative size.
1959 Change the signature to match that of plain 'read' and 'write'; see
1960 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
1961 * lisp.h: Update prototypes of emacs_write and emacs_read.
1963 2011-04-11 Eli Zaretskii <eliz@gnu.org>
1965 * xdisp.c (redisplay_window): Don't try to determine the character
1966 position of the scroll margin if the window start point w->startp
1967 is outside the buffer's accessible region. (Bug#8468)
1969 2011-04-10 Eli Zaretskii <eliz@gnu.org>
1971 Fix write-region and its subroutines for buffers > 2GB.
1972 * fileio.c (a_write, e_write): Modify declaration of arguments and
1973 local variables to support buffers larger than 2GB.
1974 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
1976 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
1977 argument, local variables, and return value.
1979 * lisp.h: Update prototypes of emacs_write and emacs_read.
1981 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
1983 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
1985 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
1987 Fix more problems found by GCC 4.6.0's static checks.
1989 * xdisp.c (vmessage): Use a better test for character truncation.
1991 * charset.c (load_charset_map): <, not <=, for optimization,
1992 and to avoid potential problems with integer overflow.
1993 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1994 * casetab.c (set_identity, shuffle): Likewise.
1995 * editfns.c (Fformat): Likewise.
1996 * syntax.c (skip_chars): Likewise.
1998 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
1999 This also lets GCC 4.6.0 generate slightly better loop code.
2001 * callint.c (Fcall_interactively): <, not <=, for optimization.
2002 (Fcall_interactively): Count the number of arguments produced,
2003 not the number of arguments given. This is simpler and lets GCC
2004 4.6.0 generate slightly better code.
2006 * ftfont.c: Distingish more carefully between FcChar8 and char.
2007 The previous code passed unsigned char * to a functions like
2008 strlen and xstrcasecmp that expect char *, which does not
2009 conform to the C standard.
2010 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
2011 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
2012 char * when the C standard requires it.
2014 * keyboard.c (read_char): Remove unused var.
2016 * eval.c: Port to Windows vsnprintf (Bug#8435).
2018 (SIZE_MAX): Define if the headers do not.
2019 (verror): Do not give up if vsnprintf returns a negative count.
2020 Instead, grow the buffer. This ports to Windows vsnprintf, which
2021 does not conform to C99. Problem reported by Eli Zaretskii.
2022 Also, simplify the allocation scheme, by avoiding the need for
2023 calling realloc, and removing the ALLOCATED variable.
2025 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
2027 Remove invocations of doprnt, as Emacs now uses vsnprintf.
2028 But keep the doprint source code for now, as we might revamp it
2029 and use it again (Bug#8435).
2030 * lisp.h (doprnt): Remove.
2031 * Makefile.in (base_obj): Remove doprnt.o.
2032 * deps.mk (doprnt.o): Remove.
2034 error: Print 32- and 64-bit integers portably (Bug#8435).
2035 Without this change, on typical 64-bit hosts error ("...%d...", N)
2036 was used to print both 32- and 64-bit integers N, which relied on
2038 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
2040 * lisp.h (error, verror): Mark as printf-like functions.
2041 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
2042 Report overflow in size calculations when allocating printf buffer.
2043 Do not truncate output string at its first null byte.
2044 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
2045 Truncate the output at a character boundary, since vsnprintf does not
2047 * charset.c (check_iso_charset_parameter): Convert internal
2048 character to string before calling 'error', since %c now has the
2050 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
2051 overflow when computing char to be passed to 'error'. Do not
2052 pass Lisp_Object to 'error'; pass the integer instead.
2053 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
2054 formatted with plain %d.
2056 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
2058 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
2060 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
2062 * xterm.c (x_catch_errors): Remove duplicate declaration.
2064 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
2066 * xdisp.c, lisp.h (message_nolog): Remove; unused.
2068 2011-04-10 Jim Meyering <meyering@redhat.com>
2070 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
2071 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
2072 return ssize_t not "int", and use size_t as the buffer length.
2073 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
2074 * gnutls.h: Update declarations.
2075 * process.c (read_process_output): Use ssize_t, to match.
2076 (send_process): Likewise.
2078 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2080 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
2082 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
2084 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
2085 Use unsigned char, to match FcChar8 type definition.
2087 * xterm.c (handle_one_xevent):
2088 * xmenu.c (create_and_show_popup_menu):
2089 * xselect.c (x_decline_selection_request)
2090 (x_reply_selection_request): Avoid type-punned deref of X events.
2092 2011-04-09 Eli Zaretskii <eliz@gnu.org>
2094 Fix some uses of `int' instead of EMACS_INT.
2095 * search.c (string_match_1, fast_string_match)
2096 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
2097 (scan_buffer, find_next_newline_no_quit)
2098 (find_before_next_newline, search_command, Freplace_match)
2099 (Fmatch_data): Make some `int' variables be EMACS_INT.
2101 * xdisp.c (display_count_lines): 3rd argument and return value now
2102 EMACS_INT. All callers changed.
2103 (pint2hrstr): Last argument is now EMACS_INT.
2105 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
2106 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

2110 (decode_coding_ccl, decode_coding_charset)
2111 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.

2118 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
2119 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
2121 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
2122 (encode_invocation_designation): Last argument P_NCHARS is now
2124 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
2125 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
2127 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
2130 * ccl.c (Fccl_execute_on_string): Declare some variables
2133 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

2141 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
2143 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
2145 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
2147 * keyboard.c (read_char): Call Lisp function help-form-show,
2148 instead of using internal_with_output_to_temp_buffer.
2149 (Qhelp_form_show): New var.
2150 (syms_of_keyboard): Use DEFSYM macro.
2152 * print.c (internal_with_output_to_temp_buffer): Function deleted.
2154 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
2156 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
2158 * process.c (Flist_processes): Remove to Lisp.
2159 (list_processes_1): Delete.
2161 2011-04-06 Eli Zaretskii <eliz@gnu.org>

2165 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
2167 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
2169 Fix more problems found by GCC 4.6.0's static checks.
2171 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
2173 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
2175 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
2177 * xdisp.c (vmessage): Mark as a printf-like function.
2179 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
2181 * sound.c (sound_warning): Don't crash if arg contains a printf format.
2183 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
2184 printf-like functions.
2185 (tiff_load): Add casts to remove these marks before passing them
2186 to system-supplied API.
2188 * eval.c (Fsignal): Remove excess argument to 'fatal'.
2190 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
2191 This avoids several warnings with gcc -Wstrict-overflow.
2192 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
2193 directly, rather than having caller test rule sign. This avoids
2194 some unnecessary tests.
2195 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
2196 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
2197 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
2199 * xfont.c (xfont_text_extents): Remove var that was set but not used.
2200 (xfont_open): Avoid unnecessary tests.
2202 * composite.c (composition_gstring_put_cache): Use unsigned integer.

2211 by using the new macro.
2213 * textprop.c (set_text_properties_1): Change while to do-while,
2214 since the condition is always true at first.
2216 * intervals.c (graft_intervals_into_buffer): Mark var as used.
2217 (interval_deletion_adjustment): Return unsigned value.
2220 * process.c (list_processes_1, create_pty, read_process_output):

2229 * syntax.c (scan_words): Remove var that was set but not used.
2230 (update_syntax_table): Use unsigned instead of int.
2232 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

2234 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
2236 * print.c (print_error_message): Avoid int overflow.
2238 * font.c (font_list_entities): Redo for clarity,
2239 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
2241 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
2242 (font_score): Avoid potential overflow in diff calculation.
2244 * fns.c (substring_both): Remove var that is set but not used.
2245 (sxhash): Redo loop for clarity and to avoid wraparound warning.
2247 * eval.c (funcall_lambda): Rename local to avoid shadowing.
2249 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
2250 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
2251 can always succeed if overflow has undefined behavior.
2253 * search.c (boyer_moore, wordify): Remove vars set but not used.
2254 (wordify): Omit three unnecessary tests.
2256 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
2257 All callers changed. This avoids the need for an unused var.
2259 * casefiddle.c (casify_region): Remove var that is set but not used.
2261 * dired.c (file_name_completion): Remove var that is set but not used.
2263 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
2265 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
2266 (Finsert_file_contents): Remove unnecessary code checking fd.
2268 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
2269 Check for integer overflow on size calculations.
2271 * buffer.c (Fprevious_overlay_change): Remove var that is set
2274 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
2275 Remove vars that are set but not used.
2276 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
2277 (timer_check_2): Mark vars as initialized.
2279 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
2281 * image.c (lookup_image): Remove var that is set but not used.
2282 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
2284 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
2285 that are set but not used.
2287 * xfns.c (make_invisible_cursor): Don't return garbage
2288 if XCreateBitmapFromData fails (Bug#8410).

2291 Remove vars that are set but not used.
2293 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

2297 Remove var that is set but not used.
2298 (scroll_bar_windows_size): Now size_t, not int.
2299 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
2302 * xfaces.c (realize_named_face): Remove vars that are set but not used.
2303 (map_tty_color) [!defined MSDOS]: Likewise.

2307 * coding.c: Remove vars that are set but not used.
2308 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
2309 All callers changed.
2310 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
2311 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
2312 (decode_coding_charset): Remove vars that are set but not used.
2314 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
2315 that is set but not used.
2317 * print.c (print_object): Remove var that is set but not used.
2319 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
2320 The gnulib version avoids calling malloc in the usual case,
2321 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
2322 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
2323 * filelock.c (current_lock_owner): Likewise.
2324 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
2325 * sysdep.c: Include allocator.h, careadlinkat.h.
2326 (emacs_no_realloc_allocator): New static constant.

2333 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
2334 first non-nil return value).
2336 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
2338 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
2339 if not defined (Bug#8403).
2341 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2343 * xdisp.c (display_count_lines): Remove parameter `start',
2344 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
2345 (get_char_face_and_encoding): Remove parameter `multibyte_p',
2346 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
2347 (fill_stretch_glyph_string): Remove parameters `row' and `area',
2348 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
2349 and thereabouts. All callers changed.
2350 (get_per_char_metric): Remove parameter `f', unused since
2351 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
2353 2011-04-02 Jim Meyering <meyering@redhat.com>
2355 do not dereference NULL upon failed strdup
2356 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
2357 (ns_get_family): Likewise.
2359 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2361 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
2363 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
2365 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
2368 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
2370 Add lexical binding.
2372 * window.c (Ftemp_output_buffer_show): New fun.
2373 (Fsave_window_excursion):
2374 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
2376 * lread.c (lisp_file_lexically_bound_p): New function.
2377 (Fload): Bind Qlexical_binding.
2378 (readevalloop): Remove `evalfun' arg.
2379 Bind Qinternal_interpreter_environment.
2380 (Feval_buffer): Bind Qlexical_binding.
2381 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
2383 (syms_of_lread): Declare `lexical-binding'.
2385 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
2387 * keyboard.c (eval_dyn): New fun.
2388 (menu_item_eval_property): Use it.
2390 * image.c (parse_image_spec): Use Ffunctionp.
2392 * fns.c (concat, mapcar1): Accept byte-code-functions.
2394 * eval.c (Fsetq): Handle lexical vars.
2395 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
2396 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
2397 (FletX, Flet): Obey lexical binding.
2398 (Fcommandp): Handle closures.
2399 (Feval): New `lexical' arg.
2400 (eval_sub): New function extracted from Feval. Use it almost
2401 everywhere where Feval was used. Look up vars in lexical env.
2403 (Ffunctionp): Move from subr.el.
2404 (Ffuncall): Handle closures.
2405 (apply_lambda): Remove `eval_flags'.
2406 (funcall_lambda): Handle closures and new byte-code-functions.
2407 (Fspecial_variable_p): New function.
2408 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
2409 but without exporting it to Lisp.
2411 * doc.c (Fdocumentation, store_function_docstring):
2412 * data.c (Finteractive_form): Handle closures.
2414 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
2417 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
2419 (exec_byte_code): New function extracted from Fbyte_code to handle new
2420 calling convention for byte-code-functions. Add new byte-codes.
2422 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
2424 * alloc.c (Fmake_symbol): Init new `declared_special' field.
2426 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2428 * xdisp.c (redisplay_internal): Fix prototype.
2430 2011-03-31 Eli Zaretskii <eliz@gnu.org>
2432 * xdisp.c (SCROLL_LIMIT): New macro.
2433 (try_scrolling): Use it when setting scroll_limit.
2434 Limit scrolling to 100 screen lines.
2435 (redisplay_window): Even when falling back on "recentering",
2436 position point in the window according to scroll-conservatively,
2437 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
2439 (try_scrolling): When point is above the window, allow searching
2440 as far as scroll_max, or one screenful, to compute vertical
2441 distance from PT to the scroll margin position. This prevents
2442 try_scrolling from unnecessarily failing when
2443 scroll-conservatively is set to a value slightly larger than the
2444 window height. Clean up the case of PT below the margin at bottom
2445 of window: scroll_max can no longer be INT_MAX. When aggressive
2446 scrolling is in use, don't let point enter the opposite scroll
2447 margin as result of the scroll.
2448 (syms_of_xdisp) <scroll-conservatively>: Document the
2449 threshold of 100 lines for never-recentering scrolling.
2451 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2453 * dispextern.h (move_it_by_lines):
2454 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
2455 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
2456 (message_log_check_duplicate): Remove parameters `prev_bol' and
2457 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
2458 (redisplay_internal): Remove parameter `preserve_echo_area',
2459 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
2461 * indent.c (Fvertical_motion):
2462 * window.c (window_scroll_pixel_based, Frecenter):
2463 Don't pass `need_y_p' to `move_it_by_lines'.
2465 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
2467 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
2468 steal a few bits to be more compact.
2469 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
2470 Remove unneeded casts.
2472 * bytecode.c (Fbyte_code): CAR and CDR can GC.
2474 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
2476 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
2477 binding" message (bug#7967).
2479 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
2481 Fix more problems found by GCC 4.6.0's static checks.
2483 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
2484 Remove unused local var.
2486 * editfns.c (Fmessage_box): Remove unused local var.
2488 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
2489 (note_mode_line_or_margin_highlight, note_mouse_highlight):
2490 Omit unused local vars.
2491 * window.c (shrink_windows): Omit unused local var.
2492 * menu.c (digest_single_submenu): Omit unused local var.
2493 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
2494 Omit unused local var.
2496 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
2497 Don't assume string length fits in int.
2498 (keyremap_step, read_key_sequence): Use size_t for sizes.
2499 (read_key_sequence): Don't check last_real_key_start redundantly.
2501 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
2502 instead of alloca (Bug#8344).
2504 * eval.c (Fbacktrace): Don't assume nargs fits in int.
2505 (Fbacktrace_frame): Don't assume nframes fits in int.
2507 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
2509 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
2512 * term.c (produce_glyphless_glyph): Remove unnecessary test.
2514 * cm.c (calccost): Turn while-do into do-while, for clarity.
2516 * keyboard.c (syms_of_keyboard): Use the same style as later
2517 in this function when indexing through an array. This also
2518 works around GCC bug 48267.
2520 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
2522 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
2524 * chartab.c (sub_char_table_ref_and_range): Redo for slight
2525 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
2527 * keyboard.c, keyboard.h (num_input_events): Now size_t.
2528 This avoids undefined behavior on integer overflow, and is a bit
2529 more convenient anyway since it is compared to a size_t variable.
2531 Variadic C functions now count arguments with size_t, not int.
2532 This avoids an unnecessary limitation on 64-bit machines, which
2533 caused (substring ...) to crash on large vectors (Bug#8344).
2534 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
2535 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

2537 (struct gcpro.nvars): Now size_t, not int. All uses changed.
2538 * data.c (arith_driver, float_arith_driver): Likewise.
2539 * editfns.c (general_insert_function): Likewise.

2543 * fns.c (concat): Likewise.
2544 * frame.c (x_set_frame_parameters): Likewise.
2545 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
2546 0 if not found, not -1. All callers changed.
2548 * alloc.c (garbage_collect): Don't assume stack size fits in int.
2549 (stack_copy_size): Now size_t, not int.
2550 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
2552 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
2554 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
2555 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2556 All callers changed.
2558 * lisp.h (multibyte_char_to_unibyte):
2559 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
2560 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2561 * character.h (CHAR_TO_BYTE8):
2562 * cmds.c (internal_self_insert):

2564 * keymap.c (push_key_description):
2565 * search.c (Freplace_match):
2566 * xdisp.c (message_dolog, set_message_1): All callers changed.
2568 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
2570 * keyboard.c (safe_run_hook_funcall): New function.
2571 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
2572 don't set the hook to nil, but remove the offending function instead.
2573 (Qcommand_hook_internal): Remove, unused.
2574 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
2575 Vcommand_hook_internal.
2577 * eval.c (enum run_hooks_condition): Remove.
2578 (funcall_nil, funcall_not): New functions.
2579 (run_hook_with_args): Call each function through a `funcall' argument.
2580 Remove `cond' argument, now redundant.
2581 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)

2589 * print.c (strout): Remove parameter `multibyte', unused since
2590 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
2592 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
2593 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
2594 All callers changed.
2596 * w32.c (_wsa_errlist): Use braces for struct initializers.
2598 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
2599 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
2600 All callers changed.
2601 (string_buffer_position): Likewise. Also, make static (it's never
2602 used outside xdisp.c).
2603 (cursor_row_p): Remove parameter `w', unused since
2604 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
2605 (decode_mode_spec): Remove parameter `precision', introduced during
2606 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.

2658 * keyboard.c (read_char):
2659 * w32menu.c (w32_menu_display_help):
2660 * xmenu.c (show_help_event, menu_help_callback):

2669 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
2670 (gap_left, gap_right): Don't call it.
2672 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
2674 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
2675 incurred during fontification.
2677 2011-03-25 Juanma Barranquero <lekktu@gmail.com>

2743 2011-03-23 Julien Danjou <julien@danjou.info>
2745 * term.c (Fsuspend_tty, Fresume_tty):
2746 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
2747 * window.c (temp_output_buffer_show):

2755 * buffer.c (Fkill_all_local_variables):
2756 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
2758 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
2759 unconditionnaly since it does the check itself.
2761 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
2763 Fix more problems found by GCC 4.5.2's static checks.
2765 * coding.c (encode_coding_raw_text): Avoid unnecessary test
2766 the first time through the loop, since we know p0 < p1 then.
2767 This also avoids a gcc -Wstrict-overflow warning.
2769 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
2770 leading to a memory leak, possible in functions like
2771 load_charset_map_from_file that can allocate an unbounded number
2772 of objects (Bug#8318).
2774 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
2775 that could (at least in theory) be that large.
2777 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
2778 This is less likely to overflow, and avoids undefined behavior if
2779 overflow does occur. All callers changed. Use strtoul to scan
2780 for the unsigned long integer.

2797 * process.c (Fmake_network_process): Use socklen_t, not int,
2798 where POSIX says socklen_t is required in portable programs.
2799 This fixes a porting bug on hosts like 64-bit HP-UX, where

2820 * terminfo.c: Include tparam.h, to check interfaces.
2821 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

2872 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
2874 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
2876 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
2877 clobbering (Bug#8298).
2878 * sysdep.c (sys_subshell): Likewise.
2879 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
2881 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
2882 This should get cleaned up, so that child_setup has the
2883 same signature on all platforms.
2885 * callproc.c (call_process_cleanup): Now static.
2886 (relocate_fd): Rename locals to avoid shadowing.
2888 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

2947 n rather than nn, a way that does not involve shadowing.
2948 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
2950 * deps.mk (unexalpha.o): Remove; unused.
2952 New file unexec.h, the (simple) interface for unexec (Bug#8267).

2977 * font.c (font_unparse_fcname): Abort in an "impossible" situation
2978 instead of using an uninitialized var.
2979 (font_sort_entities): Mark var as initialized.

3054 Use functions, not macros, for up- and down-casing (Bug#8254).
3055 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3056 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
3057 to use the following functions instead of these macros.
3058 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
3059 EMACS_INT, since callers assume the returned value fits in int.
3060 (upcase1): Likewise, for UPCASE_TABLE.
3061 (uppercasep, lowercasep, upcase): New static inline functions.
3062 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

3072 (regex_compile, re_match_2_internal): Mark locals as initialized.
3073 (RETALLOC_IF): Define only if needed.
3074 (WORDCHAR_P): Likewise. This one is never needed, but is used
3075 only in a comment talking about a compiler bug, so put inside
3076 the #if 0 of that comment.
3077 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
3078 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
3081 * search.c (boyer_moore): Rename locals to avoid shadowing.

3106 gcpro1, gcpro2, etc.
3107 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
3109 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
3110 argument, for consistency with GCPRO2_VAR, etc: it is now the
3111 prefix of the variable, not the variable itself. All uses
3113 * dired.c (directory_files_internal, file_name_completion):
3114 Rename locals to avoid shadowing.
3116 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
3117 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
3118 dired.c's scmp function, had undefined behavior.
3119 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
3120 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
3121 * buffer.h: ... to here, because these macros use current_buffer,
3122 and the new implementation with inline functions needs to have
3123 current_buffer in scope now, rather than later when the macros
3125 (downcase, upcase1): New static inline functions.
3126 (DOWNCASE, UPCASE1): Reimplement using these functions.
3127 This avoids undefined behavior in expressions like
3128 DOWNCASE (x) == DOWNCASE (y), which previously suffered
3129 from race conditions in accessing the global variables
3130 case_temp1 and case_temp2.
3131 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
3132 * lisp.h (case_temp1, case_temp2): Remove their decls.
3133 * character.h (ASCII_CHAR_P): Move from here ...
3134 * lisp.h: ... to here, so that the inline functions mentioned

3139 * fileio.c (file_name_as_directory, directory_file_name):
3140 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
3142 (file_name_as_directory): Use const pointers when appropriate.
3143 (Fexpand_file_name): Likewise. In particular, newdir might
3144 point at constant storage, so make it a const pointer.
3145 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
3146 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
3148 (Fset_file_times, Finsert_file_contents, auto_save_error):

3158 so that gcc does not warn that these functions aren't declared.
3160 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
3161 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

3166 (lock_file_1): Rename local to avoid shadowing.
3168 * buffer.c (fix_overlays_before): Mark locals as initialized.
3169 (fix_start_end_in_overlays): Likewise. This function should be
3170 simplified by using pointers-to-pointers, but that's a different
3172 (switch_to_buffer_1): Now static.
3173 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
3174 (report_overlay_modification): Rename locals to avoid shadowing.
3176 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
3177 Fix pointer signedness issue.
3178 (sys_subshell): Mark local as volatile if checking for lint,
3179 to suppress a gcc -Wclobbered warning that does not seem to be right.
3180 (MAXPATHLEN): Define only if needed.
3182 * process.c (serial_open, serial_configure): Move decls from here ...
3183 * systty.h: ... to here, so that they can be checked.
3185 * fns.c (get_random, seed_random): Move extern decls from here ...
3186 * lisp.h: ... to here, so that they can be checked.
3188 * sysdep.c (reset_io): Now static.

3222 if GCC considers string literals to be constants.
3224 * lisp.h (fatal_error_signal): Add decl, since it's exported.
