1 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
3 * gnutls.c: Remove unused macros.
4 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
5 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
6 Remove macros that are defined and never used.
7 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
9 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12 (Fx_get_selection_internal): Minor cleanup.
13 (Fx_own_selection_internal): Rename arguments for consistency with
16 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
18 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
22 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
24 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
26 * dispnew.c (scrolling_window): Don't exclude the case that the
27 last enabled row in the desired matrix touches the bottom boundary.
29 2011-05-21 Glenn Morris <rgm@gnu.org>
31 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
32 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
33 and add some more files.
35 2011-05-20 Eli Zaretskii <eliz@gnu.org>
37 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
38 report_file_error introduced by the change from 2011-05-07.
40 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
42 * systime.h (Time): Define only if emacs is defined.
43 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
44 where the include path doesn't have X11/X.h by default. See
45 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
47 2011-05-20 Kenichi Handa <handa@m17n.org>
49 * composite.c (find_automatic_composition): Fix previous change.
51 2011-05-20 Glenn Morris <rgm@gnu.org>
53 * lisp.mk: New file, split from Makefile.in.
54 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
56 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
58 2011-05-19 Glenn Morris <rgm@gnu.org>
60 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
61 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
62 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
63 (lisp): Set the order to that of loadup.el.
64 (shortlisp): Make it a copy of $lisp.
65 (SOME_MACHINE_LISP): Remove.
66 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
67 Use just $shortlisp, not $SOME_MACHINE_LISP too.
69 2011-05-18 Kenichi Handa <handa@m17n.org>
71 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
72 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
73 (find_automatic_composition): Mostly rewrite for efficiency.
75 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
77 * makefile.w32-in: Update dependencies.
79 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
81 * menu.c: Include limits.h (fixes the MS-Windows build broken by
84 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
86 Fix some integer overflow issues, such as string length overflow.
88 * insdel.c (count_size_as_multibyte): Check for string overflow.
90 * character.c (lisp_string_width): Check for string overflow.
91 Use EMACS_INT, not int, for string indexes and lengths; in
92 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
93 the resulting string length overflows an EMACS_INT; instead,
94 report a string overflow if no precision given. When checking for
95 precision exhaustion, use a check that cannot possibly have
96 integer overflow. (Bug#8675)
97 * character.h (lisp_string_width): Adjust to new signature.
99 * alloc.c (string_overflow): New function.
100 (Fmake_string): Use it. This doesn't change behavior, but saves
101 a few bytes and will simplify future changes.
102 * character.c (string_escape_byte8): Likewise.
103 * lisp.h (string_overflow): New decl.
105 Fixups, following up to the user-interface timestamp change.
106 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
107 for UI timestamps, instead of unsigned long.
108 * msdos.c (mouse_get_pos): Likewise.
109 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
110 * w32gui.h (Time): Define by including "systime.h" rather than by
111 declaring it ourselves. (Bug#8664)
113 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
114 * image.c (clear_image_cache): Likewise.
116 * term.c (term_mouse_position): Don't assume time_t wraparound.
118 Be more systematic about user-interface timestamps.
119 Before, the code sometimes used 'Time', sometimes 'unsigned long',
120 and sometimes 'EMACS_UINT', to represent these timestamps. This
121 change causes it to use 'Time' uniformly, as that's what X uses.
122 This makes the code easier to follow, and makes it easier to catch
123 integer overflow bugs such as Bug#8664.
124 * frame.c (Fmouse_position, Fmouse_pixel_position):
125 Use Time, not unsigned long, for user-interface timestamps.
126 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
127 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
128 * keyboard.h (last_event_timestamp): Likewise.
129 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
130 * menu.h (xmenu_show): Likewise.
131 * term.c (term_mouse_position): Likewise.
132 * termhooks.h (struct input_event.timestamp): Likewise.
133 (struct terminal.mouse_position_hook): Likewise.
134 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
135 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
136 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
137 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
139 * menu.h, termhooks.h: Include "systime.h", for Time.
141 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
142 Don't assume that the difference between two unsigned long values
143 can fit into an integer. At this point, we know button_down_time
144 <= event->timestamp, so the difference must be nonnegative, so
145 there's no need to cast the result if double-click-time is
146 nonnegative, as it should be; check that it's nonnegative, just in
147 case. This bug is triggered when events are more than 2**31 ms
148 apart (about 25 days). (Bug#8664)
150 * xselect.c (last_event_timestamp): Remove duplicate decl.
151 (x_own_selection): Remove needless cast to unsigned long.
153 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
154 that always fit in int. Use a sentinel instead of a counter, to
155 avoid a temp and to allay GCC's concerns about possible int overflow.
156 * frame.h (struct frame): Use int for menu_bar_items_used
157 instead of EMACS_INT, since it always fits in int.
159 * menu.c (grow_menu_items): Check for int overflow.
161 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
163 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
164 Before, the code was not consistent. These values cannot exceed
165 2**31 - 1 so there's no need to make them unsigned.
166 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
167 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
168 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
170 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
172 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
173 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
174 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
175 presumably because the widths might not match.
177 * window.c (size_window): Avoid needless test at loop start.
179 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
181 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
183 2011-05-12 Drew Adams <drew.adams@oracle.com>
185 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
187 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
189 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
190 `width' to `bar_area_x' and `bar_area_width', respectively.
191 (x_scroll_run): Take account of fringe background extension.
193 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
194 Rename local vars `left' and `width' to `bar_area_x' and
195 `bar_area_width', respectively.
196 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
197 background extension.
199 2011-05-10 Jim Meyering <meyering@redhat.com>
201 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
203 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
205 * image.c (Finit_image_library): Return t for built-in image types,
206 like pbm and xbm. (Bug#8640)
208 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
210 * w32menu.c (set_frame_menubar): Fix submenu allocation.
212 2011-05-07 Eli Zaretskii <eliz@gnu.org>
214 * w32console.c (Fset_screen_color): Doc fix.
215 (Fget_screen_color): New function.
216 (syms_of_ntterm): Defsubr it.
218 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
219 unlink the temporary file if Fcall_process didn't create it in the
221 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
222 child process will be redirected to a file specified with `:file'.
223 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
224 cue to call_process_cleanup not to close that handle.
226 2011-05-07 Ben Key <bkey76@gmail.com>
228 * makefile.w32-in: The bootstrap-temacs rule now makes use of
229 one of two shell specific rules, either bootstrap-temacs-CMD or
230 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
231 to the previous implementation of the bootstrap-temacs rule.
232 The bootstrap-temacs-CMD rule is similar to the previous
233 implementation of the bootstrap-temacs rule except that it
234 makes use of the ESC_CFLAGS variable instead of the CFLAGS
237 These changes, along with some changes to nt/configure.bat,
238 nt/gmake.defs, and nt/nmake.defs, are required to extend my
239 earlier fix to add support for --cflags and --ldflags options
240 that include quotes so that it works whether make uses cmd or
243 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
245 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
246 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
248 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
249 a string. Handle both cases.
250 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
251 (Fdbus_register_method): Use Qinvalid_function.
253 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
255 * makefile.w32-in: Update dependencies.
256 (LISP_H): Add inttypes.h and stdin.h.
257 (PROCESS_H): Add unistd.h.
259 2011-05-06 Eli Zaretskii <eliz@gnu.org>
261 * lread.c: Include limits.h (fixes the MS-Windows build broken by
262 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
264 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
266 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
268 * term.c (vfatal): Remove stray call to va_end.
269 It's not needed and the C Standard doesn't allow it here anyway.
271 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
272 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
274 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
277 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
279 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
281 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
283 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
285 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
287 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
288 * charset.c (Fdefine_charset_internal): Don't initialize
289 charset.code_space[15]. The value was garbage, on hosts with
290 32-bit int (Bug#8600).
292 * lread.c (read_integer): Be more consistent with string-to-number.
293 Use string_to_number to do the actual conversion; this avoids
294 rounding errors and fixes some other screwups. Without this fix,
295 for example, #x1fffffffffffffff was misread as -2305843009213693952.
296 (digit_to_number): Move earlier, for benefit of read_integer.
297 Return -1 if the digit is out of range for the base, -2 if it is
298 not a digit in any supported base. (Bug#8602)
300 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
302 * dispnew.c (scrolling_window): Return 1 if we scrolled,
303 to match comment at start of function. This also removes a
304 GCC warning about overflow in a 32+64-bit port.
306 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
308 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
309 Reported by Stefan Monnier in
310 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
311 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
312 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
314 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
315 (EMACS_UINTPTR): Likewise, with uintptr_t.
317 * lisp.h: Prefer 64-bit EMACS_INT if available.
318 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
319 on 32-bit hosts that have 64-bit int, so that they can access
321 However, temporarily disable this change unless the temporary
322 symbol WIDE_EMACS_INT is defined.
324 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
326 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
327 This removes an assumption that EMACS_INT and long are the same
328 width as pointers. The assumption is true for Emacs porting targets
329 now, but we want to make other targets possible.
330 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
331 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
332 In the rest of the code, change types of integers that hold casted
333 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
334 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
335 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
336 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
337 No need to cast type when ORing.
338 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
339 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
340 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
341 assume EMACS_INT is the same width as char *.
342 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
343 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
344 Remove no-longer-needed casts.
345 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
346 (xg_tool_bar_help_callback, xg_make_tool_item):
347 Use EMACS_INTPTR to hold an integer
348 that will be cast to void *; this can avoid a GCC warning
349 if EMACS_INT is not the same width as void *.
350 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
351 * xdisp.c (display_echo_area_1, resize_mini_window_1):
352 (current_message_1, set_message_1):
353 Use a local to convert to proper width without a cast.
354 * xmenu.c (dialog_selection_callback): Likewise.
356 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
357 Also, don't assume VALBITS / RAND_BITS is less than 5,
358 and don't rely on undefined behavior when shifting a 1 left into
360 * lisp.h (get_random): Change signature to match.
362 * lread.c (hash_string): Use size_t, not int, for hash computation.
363 Normally we prefer signed values; but hashing is special, because
364 it's better to use unsigned division on hash table sizes so that
365 the remainder is nonnegative. Also, size_t is the natural width
366 for hashing into memory. The previous code used 'int', which doesn't
367 retain enough info to hash well into very large tables.
368 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
370 * dbusbind.c: Don't possibly lose pointer info when converting.
371 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
372 Use XPNTR rather than XHASH, so that the high-order bits of
373 the pointer aren't lost when converting through void *.
375 * eval.c (Fautoload): Don't double-shift a pointer.
377 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
379 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
381 * gnutls.c (DEF_GNUTLS_FN):
382 * image.c (DEF_IMGLIB_FN): Make function pointers static.
384 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
386 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
389 2011-05-05 Eli Zaretskii <eliz@gnu.org>
391 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
392 New version that can reserve upto 2GB of heap space.
394 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
396 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
398 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
400 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
401 `gnutls_certificate_set_x509_key_file'.
403 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
405 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
408 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
410 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
411 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
412 Remove unused parameter `fildes'.
413 * process.c (read_process_output, send_process): Don't pass it.
415 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
417 Fix previous change: the library cache is defined in w32.c.
418 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
419 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
421 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
423 Implement dynamic loading of GnuTLS on Windows.
425 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
426 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
427 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
430 * gnutls.c (Qgnutls_dll): Define.
431 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
432 (gnutls_*): Declare function pointers.
433 (init_gnutls_functions): New function to initialize function pointers.
434 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
435 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
436 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
437 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
438 (emacs_gnutls_write, emacs_gnutls_read)
439 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
440 (Fgnutls_available_p): New function.
441 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
442 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
443 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
445 * image.c: Include w32.h.
446 (Vimage_type_cache): Delete.
447 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
448 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
449 (w32_delayed_load): Move to w32.c.
451 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
453 * w32.c (QCloaded_from, Vlibrary_cache): Define.
454 (w32_delayed_load): Move from image.c. When loading a library, record
455 its filename in the :loaded-from property of the library id.
456 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
457 Initialize and staticpro them.
458 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
460 * process.c: Include lisp.h before w32.h, not after.
461 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
462 instead of gnutls_record_check_pending.
464 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
466 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
468 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

513 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
514 rather than `XVECTOR (FOO)->size'.
516 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
517 inttypes.h, as a gnulib replacement is used if it not available in
520 2011-04-21 Eli Zaretskii <eliz@gnu.org>
522 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
523 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
524 of MOST_POSITIVE_FIXNUM. (Bug#8528)
526 * coding.c (coding_alloc_by_realloc): Error out if destination
527 will grow beyond MOST_POSITIVE_FIXNUM.
528 (decode_coding_emacs_mule): Abort if there isn't enough place in
529 charbuf for the composition carryover bytes. Reserve an extra
530 space for up to 2 characters produced in a loop.
531 (decode_coding_iso_2022): Abort if there isn't enough place in
532 charbuf for the composition carryover bytes.
534 2011-04-21 Eli Zaretskii <eliz@gnu.org>
536 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
537 aborting when %lld or %lll format is passed.
538 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
539 %llo or %llx format is passed. (Bug#8545)
541 * window.c (window_scroll_line_based): Use a marker instead of
542 simple variables to record original value of point. (Bug#7952)
544 * doprnt.c (doprnt): Fix the case where a multibyte sequence
545 produced by %s or %c overflows available buffer space. (Bug#8545)
547 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
549 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
550 (SIZE_MAX): Move defn after all includes, as they might #define it.
552 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
554 * w32.c (init_environment): Warn about defaulting HOME to C:\.
556 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
558 * keyboard.c (Qdelayed_warnings_hook): Define.
559 (command_loop_1): Run `delayed-warnings-hook'
560 if Vdelayed_warnings_list is non-nil.
561 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
562 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
564 2011-04-28 Eli Zaretskii <eliz@gnu.org>
566 * doprnt.c (doprnt): Don't return value smaller than the buffer
567 size if the message was truncated. (Bug#8545).
569 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
571 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

578 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
580 * makefile.w32-in: Update dependencies.
582 2011-04-27 Eli Zaretskii <eliz@gnu.org>
584 Improve `doprnt' and its usage. (Bug#8545)
585 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
586 `format_end'. Remove support for %l as a conversion specifier.
587 Don't use xrealloc. Improve diagnostics when the %l size modifier
588 is used. Update the commentary.
590 * eval.c (verror): Simplify calculation of size_t.

600 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
602 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
603 This makes this file independent of the recent pseudovector change.
605 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
607 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
609 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
610 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
612 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
614 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
615 GCC 4.6.0 optimizes based on type-based alias analysis.
616 For example, if b is of type struct buffer * and v of type struct
617 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
618 != &v->size, and therefore "v->size = 1; b->size = 2; return
619 v->size;" must therefore return 1. This assumption is incorrect
620 for Emacs, since it type-puns struct Lisp_Vector * with many other
621 types. To fix this problem, this patch adds a new type struct
622 vectorlike_header that documents the constraints on layout of vectors
623 and pseudovectors, and helps optimizing compilers not get fooled
624 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
625 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
626 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
628 (XSETPVECTYPE): Rewrite in terms of new macro.
629 (XSETPVECTYPESIZE): New macro, specifying both type and size.
630 This is a bit clearer, and further avoids the possibility of
631 undesirable aliasing.
632 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
633 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
634 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
635 since Lisp_Subr is a special case (no "next" field).
636 (ASIZE): Now uses header.size rather than size.
637 All previous uses of XVECTOR (foo)->size replaced to use this macro,
638 to avoid the hassle of writing XVECTOR (foo)->header.size.
639 (struct vectorlike_header): New type.
640 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
641 object, to help avoid aliasing.
642 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
643 (SUBRP): Likewise, since Lisp_Subr is a special case.
644 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
645 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
646 (struct Lisp_Hash_Table): Combine first two members into a single
647 struct vectorlike_header member. All uses of "size" and "next" members
648 changed to be "header.size" and "header.next".
649 * buffer.h (struct buffer): Likewise.
650 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
651 * frame.h (struct frame): Likewise.
652 * process.h (struct Lisp_Process): Likewise.
653 * termhooks.h (struct terminal): Likewise.
654 * window.c (struct save_window_data, struct saved_window): Likewise.
655 * window.h (struct window): Likewise.
656 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
657 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
658 * buffer.c (init_buffer_once): Likewise.
659 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
661 * process.c (Fformat_network_address): Use local var for size,
664 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
666 Make the Lisp reader and string-to-float more consistent (Bug#8525)
667 * data.c (atof): Remove decl; no longer used or needed.
668 (digit_to_number): Move to lread.c.
669 (Fstring_to_number): Use new string_to_number function, to be
670 consistent with how the Lisp reader treats infinities and NaNs.
671 Do not assume that floating-point numbers represent EMACS_INT
672 without losing information; this is not true on most 64-bit hosts.
673 Avoid double-rounding errors, by insisting on integers when
674 parsing non-base-10 numbers, as the documentation specifies.
675 * lisp.h (string_to_number): New decl, replacing ...
676 (isfloat_string): Remove.
677 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
678 (read1): Do not accept +. and -. as integers; this
679 appears to have been a coding error. Similarly, do not accept
680 strings like +-1e0 as floating point numbers. Do not report
681 overflow for integer overflows unless the base is not 10 which
682 means we have no simple and reliable way to continue.
683 Break out the floating-point parsing into a new
684 function string_to_number, so that Fstring_to_number parses
685 floating point numbers consistently with the Lisp reader.
686 (digit_to_number): Move here from data.c. Make it static inline.
687 (E_CHAR, EXP_INT): Remove, replacing with ...
688 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
689 (string_to_number): New function, replacing isfloat_string.
690 This function checks for valid syntax and produces the resulting
691 Lisp float number too. Rework it so that string-to-number
692 no longer mishandles examples like "1.0e+". Use strtoumax,
693 so that overflow for non-base-10 numbers is reported only when
694 there's no portable and simple way to convert to floating point.
696 * textprop.c (set_text_properties_1): Rewrite for clarity,
697 and to avoid GCC warning about integer overflow.
699 * intervals.h (struct interval): Use EMACS_INT for members
700 where EMACS_UINT might cause problems. See
701 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
702 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
703 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
705 (offset_intervals): Tell GCC not to worry about length overflow
706 when negating a negative length.
708 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
709 (overrun_check_free): Likewise.
711 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
712 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
715 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
716 (gnutls_make_error): Rename local to avoid shadowing.
717 (gnutls_emacs_global_deinit): ifdef out; not used.
718 (Fgnutls_boot): Use const for pointer to readonly storage.
719 Comment out unused local. Fix pointer signedness problems.
721 * lread.c (openp): Don't stuff size_t into an 'int'.
722 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
723 about possible signed overflow.
725 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
726 (GDK_KEY_g): Don't define if already defined.
727 (xg_prepare_tooltip): Avoid pointer signedness problem.
728 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
730 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
731 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
733 * xfns.c (Fx_window_property): Simplify a bit,
734 to make a bit faster and to avoid GCC 4.6.0 warning.
735 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
737 * fns.c (internal_equal): Don't assume size_t fits in int.
739 * alloc.c (compact_small_strings): Tighten assertion a little.
741 Replace pEd with more-general pI, and fix some printf arg casts.
742 * lisp.h (pI): New macro, generalizing old pEd macro to other
743 conversion specifiers. For example, use "...%"pI"d..." rather
745 (pEd): Remove. All uses replaced with similar uses of pI.
746 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
747 * alloc.c (check_pure_size): Don't overflow by converting size to int.
748 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
749 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
750 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
751 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
752 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
754 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
755 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
756 * print.c (safe_debug_print, print_object): Likewise.
757 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
759 Use pI instead of if-then-else-abort. Use %p to avoid casts,
760 avoiding the 0 flag, which is not portable.
761 * process.c (Fmake_network_process): Use pI to avoid cast.
762 * region-cache.c (pp_cache): Likewise.
763 * xdisp.c (decode_mode_spec): Likewise.
764 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
765 behavior on 64-bit hosts with printf arg.
766 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
767 (x_stop_queuing_selection_requests): Likewise.
768 (x_get_window_property): Don't truncate byte count to an 'int'
771 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
772 here, since it parses constructs like leading '-' and spaces,
773 which are not wanted; and it overflows with large numbers.
774 Instead, simply match F[0-9]+, which is what is wanted anyway.
776 * alloc.c: Remove unportable assumptions about struct layout.
777 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
778 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
779 (allocate_vectorlike, make_pure_vector): Use the new macros,
780 plus offsetof, to remove unportable assumptions about struct layout.
781 These assumptions hold on all porting targets that I know of, but
782 they are not guaranteed, they're easy to remove, and removing them
783 makes further changes easier.
785 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
786 This doesn't fix a bug but makes the code clearer.
787 (string_overrun_cookie): Now const. Use initializers that
788 don't formally overflow signed char, to avoid warnings.
789 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
790 can cause Emacs to crash when string overrun checking is enabled.
791 (allocate_buffer): Don't assume sizeof (struct buffer) is a
792 multiple of sizeof (EMACS_INT); it need not be, if
793 alignof(EMACS_INT) < sizeof (EMACS_INT).
794 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
796 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
798 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
800 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
802 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
803 supposed to be handshaking. (Bug#8556)

825 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
826 "cast to pointer from integer of different size".
828 Improve doprnt and its use in verror. (Bug#8545)
829 * doprnt.c (doprnt): Document the set of format control sequences
830 supported by the function. Use SAFE_ALLOCA instead of always
833 * eval.c (verror): Don't limit the buffer size at size_max-1, that
834 is one byte too soon. Don't use xrealloc; instead xfree and
837 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
839 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
842 * gnutls.c: Renamed global_initialized to
843 gnutls_global_initialized. Added internals for the
844 :verify-hostname-error, :verify-error, and :verify-flags
845 parameters of `gnutls-boot' and documented those parameters in the
846 docstring. Start callback support.
847 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
848 unless a fatal error occured. Call gnutls_alert_send_appropriate
849 on error. Return error code.
850 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
851 (emacs_gnutls_read): Likewise.
852 (Fgnutls_boot): Return handshake error code.

857 (emacs_gnutls_push): Likewise.
859 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
860 (emacs_gnutls_push): Likewise.
862 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)

865 buffered some data internally if no FDs are set for TLS

925 Improve overflow protection. Support `l' modifier for integer
926 conversions. Support %l conversion. Don't assume an EMACS_INT
927 argument for integer conversions and for %c.

931 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

936 * deps.mk (doprnt.o): Add back prerequisites.
937 (callint.o): Depend on character.h.
939 * eval.c (internal_lisp_condition_case): Include the handler
940 representation in the error message.
941 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
942 when breaking from the loop.
944 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
946 * callint.c (Fcall_interactively): When displaying error message
947 about invalid control letter, pass the character's codepoint, not
948 a pointer to its multibyte form. Improve display of the character

1513 so that it's not optimized away.
1514 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
1515 * dispextern.h (bidi_dump_cached_states): Remove, since it's
1516 exported only to the debugger.

1521 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
1522 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
1523 was inaccessible from Lisp.
1524 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
1525 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
1527 alloc.c: Import and export fewer symbols, and remove unused items.
1528 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING

1545 * xdisp.c (message_enable_multibyte): Now static.
1547 Declare Lisp_Object Q* variables to be 'static' if not exported.
1548 This makes it easier for human readers (and static analyzers)
1549 to see whether these variables are used from other modules.
1550 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

1561 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
1563 * lisp.h (DEFINE_FUNC): Make sname 'static'.
1565 Make Emacs functions such as Fatom 'static' by default.
1566 This makes it easier for human readers (and static analyzers)
1567 to see whether these functions can be called from other modules.
1568 DEFUN now defines a static function. To make the function external
1569 so that it can be used in other C modules, use the new macro DEFUE.

1575 Remove decls, since these functions are now static.
1576 (Funintern, Fget_internal_run_time): New decls, since these functions
1577 were already external.

1637 * sound.c (sound_cleanup, alsa_close): Likewise.
1638 * termcap.c (tgetent): Likewise.

1643 (overrun_check_free): Protoize.
1645 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
1647 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
1648 since callers should never pass a negative size.
1649 Change the signature to match that of plain 'read' and 'write'; see
1650 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
1651 * lisp.h: Update prototypes of emacs_write and emacs_read.
1653 2011-04-11 Eli Zaretskii <eliz@gnu.org>
1655 * xdisp.c (redisplay_window): Don't try to determine the character
1656 position of the scroll margin if the window start point w->startp
1657 is outside the buffer's accessible region. (Bug#8468)
1659 2011-04-10 Eli Zaretskii <eliz@gnu.org>
1661 Fix write-region and its subroutines for buffers > 2GB.
1662 * fileio.c (a_write, e_write): Modify declaration of arguments and
1663 local variables to support buffers larger than 2GB.
1664 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
1666 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
1667 argument, local variables, and return value.
1669 * lisp.h: Update prototypes of emacs_write and emacs_read.
1671 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
1673 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
1675 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
1677 Fix more problems found by GCC 4.6.0's static checks.
1679 * xdisp.c (vmessage): Use a better test for character truncation.
1681 * charset.c (load_charset_map): <, not <=, for optimization,
1682 and to avoid potential problems with integer overflow.
1683 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1684 * casetab.c (set_identity, shuffle): Likewise.
1685 * editfns.c (Fformat): Likewise.
1686 * syntax.c (skip_chars): Likewise.
1688 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
1689 This also lets GCC 4.6.0 generate slightly better loop code.
1691 * callint.c (Fcall_interactively): <, not <=, for optimization.
1692 (Fcall_interactively): Count the number of arguments produced,
1693 not the number of arguments given. This is simpler and lets GCC
1694 4.6.0 generate slightly better code.
1696 * ftfont.c: Distingish more carefully between FcChar8 and char.
1697 The previous code passed unsigned char * to a functions like
1698 strlen and xstrcasecmp that expect char *, which does not
1699 conform to the C standard.
1700 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
1701 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
1702 char * when the C standard requires it.
1704 * keyboard.c (read_char): Remove unused var.
1706 * eval.c: Port to Windows vsnprintf (Bug#8435).
1708 (SIZE_MAX): Define if the headers do not.
1709 (verror): Do not give up if vsnprintf returns a negative count.
1710 Instead, grow the buffer. This ports to Windows vsnprintf, which
1711 does not conform to C99. Problem reported by Eli Zaretskii.
1712 Also, simplify the allocation scheme, by avoiding the need for
1713 calling realloc, and removing the ALLOCATED variable.
1715 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
1717 Remove invocations of doprnt, as Emacs now uses vsnprintf.
1718 But keep the doprint source code for now, as we might revamp it
1719 and use it again (Bug#8435).
1720 * lisp.h (doprnt): Remove.
1721 * Makefile.in (base_obj): Remove doprnt.o.
1722 * deps.mk (doprnt.o): Remove.
1724 error: Print 32- and 64-bit integers portably (Bug#8435).
1725 Without this change, on typical 64-bit hosts error ("...%d...", N)
1726 was used to print both 32- and 64-bit integers N, which relied on
1728 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
1730 * lisp.h (error, verror): Mark as printf-like functions.
1731 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
1732 Report overflow in size calculations when allocating printf buffer.
1733 Do not truncate output string at its first null byte.
1734 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
1735 Truncate the output at a character boundary, since vsnprintf does not
1737 * charset.c (check_iso_charset_parameter): Convert internal
1738 character to string before calling 'error', since %c now has the
1740 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
1741 overflow when computing char to be passed to 'error'. Do not
1742 pass Lisp_Object to 'error'; pass the integer instead.
1743 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
1744 formatted with plain %d.
1746 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
1748 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
1750 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
1752 * xterm.c (x_catch_errors): Remove duplicate declaration.
1754 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
1756 * xdisp.c, lisp.h (message_nolog): Remove; unused.
1758 2011-04-10 Jim Meyering <meyering@redhat.com>
1760 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
1761 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
1762 return ssize_t not "int", and use size_t as the buffer length.
1763 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
1764 * gnutls.h: Update declarations.
1765 * process.c (read_process_output): Use ssize_t, to match.
1766 (send_process): Likewise.
1768 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1770 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
1772 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
1774 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
1775 Use unsigned char, to match FcChar8 type definition.
1777 * xterm.c (handle_one_xevent):
1778 * xmenu.c (create_and_show_popup_menu):
1779 * xselect.c (x_decline_selection_request)
1780 (x_reply_selection_request): Avoid type-punned deref of X events.
1782 2011-04-09 Eli Zaretskii <eliz@gnu.org>
1784 Fix some uses of `int' instead of EMACS_INT.
1785 * search.c (string_match_1, fast_string_match)
1786 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
1787 (scan_buffer, find_next_newline_no_quit)
1788 (find_before_next_newline, search_command, Freplace_match)
1789 (Fmatch_data): Make some `int' variables be EMACS_INT.
1791 * xdisp.c (display_count_lines): 3rd argument and return value now
1792 EMACS_INT. All callers changed.
1793 (pint2hrstr): Last argument is now EMACS_INT.
1795 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
1796 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

1809 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
1811 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
1812 (encode_invocation_designation): Last argument P_NCHARS is now
1814 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
1815 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

1835 2011-04-08 Chong Yidong <cyd@stupidchicken.com>

1878 * eval.c (Fsignal): Remove excess argument to 'fatal'.
1880 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
1881 This avoids several warnings with gcc -Wstrict-overflow.
1882 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
1883 directly, rather than having caller test rule sign. This avoids
1884 some unnecessary tests.
1885 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
1886 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
1887 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
1889 * xfont.c (xfont_text_extents): Remove var that was set but not used.
1890 (xfont_open): Avoid unnecessary tests.
1892 * composite.c (composition_gstring_put_cache): Use unsigned integer.

1895 Use EMACS_INT, not int, for length.
1897 * composite.h (COMPOSITION_DECODE_REFS): New macro,
1898 breaking out part of COMPOSITION_DECODE_RULE.
1899 (COMPOSITION_DECODE_RULE): Use it.
1900 * composite.c (get_composition_id): Remove unused local vars,
1901 by using the new macro.
1903 * textprop.c (set_text_properties_1): Change while to do-while,
1904 since the condition is always true at first.
1906 * intervals.c (graft_intervals_into_buffer): Mark var as used.
1907 (interval_deletion_adjustment): Return unsigned value.
1910 * process.c (list_processes_1, create_pty, read_process_output):

1935 (sxhash): Redo loop for clarity and to avoid wraparound warning.
1937 * eval.c (funcall_lambda): Rename local to avoid shadowing.
1939 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
1940 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
1941 can always succeed if overflow has undefined behavior.
1943 * search.c (boyer_moore, wordify): Remove vars set but not used.
1944 (wordify): Omit three unnecessary tests.
1946 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
1947 All callers changed. This avoids the need for an unused var.
1949 * casefiddle.c (casify_region): Remove var that is set but not used.
1951 * dired.c (file_name_completion): Remove var that is set but not used.
1953 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
1955 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
1956 (Finsert_file_contents): Remove unnecessary code checking fd.
1958 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
1959 Check for integer overflow on size calculations.
1961 * buffer.c (Fprevious_overlay_change): Remove var that is set
1964 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
1965 Remove vars that are set but not used.
1966 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
1967 (timer_check_2): Mark vars as initialized.
1969 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
1971 * image.c (lookup_image): Remove var that is set but not used.
1972 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
1974 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
1975 that are set but not used.
1977 * xfns.c (make_invisible_cursor): Don't return garbage
1978 if XCreateBitmapFromData fails (Bug#8410).
1980 * xselect.c (x_get_local_selection, x_handle_property_notify):
1981 Remove vars that are set but not used.
1983 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
1984 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
1986 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
1987 Remove var that is set but not used.
1988 (scroll_bar_windows_size): Now size_t, not int.
1989 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
1992 * xfaces.c (realize_named_face): Remove vars that are set but not used.
1993 (map_tty_color) [!defined MSDOS]: Likewise.
1995 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
1997 * coding.c: Remove vars that are set but not used.
1998 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
1999 All callers changed.
2000 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
2001 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
2002 (decode_coding_charset): Remove vars that are set but not used.
2004 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
2005 that is set but not used.
2007 * print.c (print_object): Remove var that is set but not used.
2009 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
2010 The gnulib version avoids calling malloc in the usual case,
2011 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
2012 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
2013 * filelock.c (current_lock_owner): Likewise.
2014 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
2015 * sysdep.c: Include allocator.h, careadlinkat.h.
2016 (emacs_no_realloc_allocator): New static constant.
2017 (emacs_readlink): New function.
2018 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

2023 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
2024 first non-nil return value).
2026 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
2028 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
2029 if not defined (Bug#8403).
2031 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2033 * xdisp.c (display_count_lines): Remove parameter `start',
2034 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
2035 (get_char_face_and_encoding): Remove parameter `multibyte_p',
2036 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

2038 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
2039 and thereabouts. All callers changed.
2040 (get_per_char_metric): Remove parameter `f', unused since
2041 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
2043 2011-04-02 Jim Meyering <meyering@redhat.com>
2045 do not dereference NULL upon failed strdup
2046 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
2047 (ns_get_family): Likewise.
2049 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
2051 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
2053 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
2055 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
2058 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
2060 Add lexical binding.
2062 * window.c (Ftemp_output_buffer_show): New fun.
2063 (Fsave_window_excursion):
2064 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
2066 * lread.c (lisp_file_lexically_bound_p): New function.
2067 (Fload): Bind Qlexical_binding.
2068 (readevalloop): Remove `evalfun' arg.
2069 Bind Qinternal_interpreter_environment.
2070 (Feval_buffer): Bind Qlexical_binding.
2071 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
2073 (syms_of_lread): Declare `lexical-binding'.
2075 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
2077 * keyboard.c (eval_dyn): New fun.
2078 (menu_item_eval_property): Use it.
2080 * image.c (parse_image_spec): Use Ffunctionp.
2082 * fns.c (concat, mapcar1): Accept byte-code-functions.
2084 * eval.c (Fsetq): Handle lexical vars.
2085 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
2086 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
2087 (FletX, Flet): Obey lexical binding.
2088 (Fcommandp): Handle closures.
2089 (Feval): New `lexical' arg.
2090 (eval_sub): New function extracted from Feval. Use it almost
2091 everywhere where Feval was used. Look up vars in lexical env.
2093 (Ffunctionp): Move from subr.el.
2094 (Ffuncall): Handle closures.
2095 (apply_lambda): Remove `eval_flags'.
2096 (funcall_lambda): Handle closures and new byte-code-functions.
2097 (Fspecial_variable_p): New function.
2098 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
2099 but without exporting it to Lisp.
2101 * doc.c (Fdocumentation, store_function_docstring):
2102 * data.c (Finteractive_form): Handle closures.
2104 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
2107 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
2109 (exec_byte_code): New function extracted from Fbyte_code to handle new
2110 calling convention for byte-code-functions. Add new byte-codes.
2112 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
2114 * alloc.c (Fmake_symbol): Init new `declared_special' field.
2116 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2118 * xdisp.c (redisplay_internal): Fix prototype.
2120 2011-03-31 Eli Zaretskii <eliz@gnu.org>
2122 * xdisp.c (SCROLL_LIMIT): New macro.
2123 (try_scrolling): Use it when setting scroll_limit.
2124 Limit scrolling to 100 screen lines.
2125 (redisplay_window): Even when falling back on "recentering",
2126 position point in the window according to scroll-conservatively,
2127 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
2129 (try_scrolling): When point is above the window, allow searching
2130 as far as scroll_max, or one screenful, to compute vertical
2131 distance from PT to the scroll margin position. This prevents
2132 try_scrolling from unnecessarily failing when
2133 scroll-conservatively is set to a value slightly larger than the
2134 window height. Clean up the case of PT below the margin at bottom
2135 of window: scroll_max can no longer be INT_MAX. When aggressive
2136 scrolling is in use, don't let point enter the opposite scroll
2137 margin as result of the scroll.
2138 (syms_of_xdisp) <scroll-conservatively>: Document the
2139 threshold of 100 lines for never-recentering scrolling.
2141 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
2143 * dispextern.h (move_it_by_lines):
2144 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
2145 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
2146 (message_log_check_duplicate): Remove parameters `prev_bol' and
2147 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
2148 (redisplay_internal): Remove parameter `preserve_echo_area',
2149 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
2151 * indent.c (Fvertical_motion):
2152 * window.c (window_scroll_pixel_based, Frecenter):
2153 Don't pass `need_y_p' to `move_it_by_lines'.
2155 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
2157 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
2158 steal a few bits to be more compact.
2159 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
2160 Remove unneeded casts.
2162 * bytecode.c (Fbyte_code): CAR and CDR can GC.
2164 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
2166 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
2167 binding" message (bug#7967).
2169 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
2171 Fix more problems found by GCC 4.6.0's static checks.
2173 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
2174 Remove unused local var.
2176 * editfns.c (Fmessage_box): Remove unused local var.
2178 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
2179 (note_mode_line_or_margin_highlight, note_mouse_highlight):
2180 Omit unused local vars.
2181 * window.c (shrink_windows): Omit unused local var.
2182 * menu.c (digest_single_submenu): Omit unused local var.
2183 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
2184 Omit unused local var.
2186 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
2187 Don't assume string length fits in int.
2188 (keyremap_step, read_key_sequence): Use size_t for sizes.
2189 (read_key_sequence): Don't check last_real_key_start redundantly.
2191 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
2192 instead of alloca (Bug#8344).
2194 * eval.c (Fbacktrace): Don't assume nargs fits in int.
2195 (Fbacktrace_frame): Don't assume nframes fits in int.
2197 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
2199 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
2202 * term.c (produce_glyphless_glyph): Remove unnecessary test.
2204 * cm.c (calccost): Turn while-do into do-while, for clarity.
2206 * keyboard.c (syms_of_keyboard): Use the same style as later
2207 in this function when indexing through an array. This also
2208 works around GCC bug 48267.
2210 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
2212 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
2214 * chartab.c (sub_char_table_ref_and_range): Redo for slight
2215 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
2217 * keyboard.c, keyboard.h (num_input_events): Now size_t.
2218 This avoids undefined behavior on integer overflow, and is a bit
2219 more convenient anyway since it is compared to a size_t variable.
2221 Variadic C functions now count arguments with size_t, not int.
2222 This avoids an unnecessary limitation on 64-bit machines, which
2223 caused (substring ...) to crash on large vectors (Bug#8344).
2224 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
2225 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

2233 * fns.c (concat): Likewise.
2234 * frame.c (x_set_frame_parameters): Likewise.
2235 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
2236 0 if not found, not -1. All callers changed.
2238 * alloc.c (garbage_collect): Don't assume stack size fits in int.
2239 (stack_copy_size): Now size_t, not int.
2240 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
2242 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
2244 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
2245 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2246 All callers changed.
2248 * lisp.h (multibyte_char_to_unibyte):
2249 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
2250 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
2251 * character.h (CHAR_TO_BYTE8):
2252 * cmds.c (internal_self_insert):
2253 * editfns.c (general_insert_function):
2254 * keymap.c (push_key_description):
2255 * search.c (Freplace_match):
2256 * xdisp.c (message_dolog, set_message_1): All callers changed.

2261 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
2262 don't set the hook to nil, but remove the offending function instead.
2263 (Qcommand_hook_internal): Remove, unused.
2264 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
2265 Vcommand_hook_internal.
2267 * eval.c (enum run_hooks_condition): Remove.
2268 (funcall_nil, funcall_not): New functions.
2269 (run_hook_with_args): Call each function through a `funcall' argument.

2283 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
2284 All callers changed.
2286 * w32.c (_wsa_errlist): Use braces for struct initializers.
2288 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
2289 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
2290 All callers changed.
2291 (string_buffer_position): Likewise. Also, make static (it's never
2292 used outside xdisp.c).
2293 (cursor_row_p): Remove parameter `w', unused since
2294 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

2444 * callint.c (Fcall_interactively):
2445 * buffer.c (Fkill_all_local_variables):
2446 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
2448 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
2449 unconditionnaly since it does the check itself.
2451 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
2453 Fix more problems found by GCC 4.5.2's static checks.
2455 * coding.c (encode_coding_raw_text): Avoid unnecessary test
2456 the first time through the loop, since we know p0 < p1 then.
2457 This also avoids a gcc -Wstrict-overflow warning.
2459 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
2460 leading to a memory leak, possible in functions like
2461 load_charset_map_from_file that can allocate an unbounded number
2462 of objects (Bug#8318).
2464 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
2465 that could (at least in theory) be that large.
2467 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
2468 This is less likely to overflow, and avoids undefined behavior if
2469 overflow does occur. All callers changed. Use strtoul to scan

2482 * fileio.c (Fcopy_file): Report error if fchown or fchmod
2485 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
2487 * process.c (Fmake_network_process): Use socklen_t, not int,
2488 where POSIX says socklen_t is required in portable programs.
2489 This fixes a porting bug on hosts like 64-bit HP-UX, where
2490 socklen_t is wider than int (Bug#8277).
2491 (Fmake_network_process, server_accept_connection):
2492 (wait_reading_process_output, read_process_output):

2507 Include tparam.h instead, since it declares them.
2508 * cm.h (PC): Remove extern decl; tparam.h now does this.
2509 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
2510 * terminfo.c: Include tparam.h, to check interfaces.
2511 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
2512 (tparam): Adjust signature to match interface in tparam.h;
2513 this removes some undefined behavior. Check that outstring and len
2514 are zero, which they always are with Emacs.
2515 * tparam.h (PC, BC, UP): New extern decls.
2517 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
2518 (xftfont_open): Rename locals to avoid shadowing.

2559 (wav_play): Initialize a variable to 0, to prevent undefined
2560 behavior (Bug#8278).
2562 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
2564 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
2566 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
2567 clobbering (Bug#8298).
2568 * sysdep.c (sys_subshell): Likewise.
2569 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
2571 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
2572 This should get cleaned up, so that child_setup has the
2573 same signature on all platforms.
2575 * callproc.c (call_process_cleanup): Now static.
2576 (relocate_fd): Rename locals to avoid shadowing.
2578 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
2580 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
2581 not to be necessary, and produces flickering.
2583 2011-03-20 Glenn Morris <rgm@gnu.org>
2585 * config.in: Remove file.
2587 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

2634 * unexelf.c (unexec): Name an expression,
2635 to avoid gcc -Wbad-function-cast warning.
2636 Use a different way to cause a compilation error if anyone uses
2637 n rather than nn, a way that does not involve shadowing.
2638 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
2640 * deps.mk (unexalpha.o): Remove; unused.
2642 New file unexec.h, the (simple) interface for unexec (Bug#8267).

2745 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2746 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
2747 to use the following functions instead of these macros.
2748 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
2749 EMACS_INT, since callers assume the returned value fits in int.

2764 (WORDCHAR_P): Likewise. This one is never needed, but is used

2796 gcpro1, gcpro2, etc.
2797 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
2799 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
2800 argument, for consistency with GCPRO2_VAR, etc: it is now the
2801 prefix of the variable, not the variable itself. All uses
2803 * dired.c (directory_files_internal, file_name_completion):
2804 Rename locals to avoid shadowing.
2806 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
2807 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
2808 dired.c's scmp function, had undefined behavior.
2809 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
2810 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
2811 * buffer.h: ... to here, because these macros use current_buffer,
2812 and the new implementation with inline functions needs to have
2813 current_buffer in scope now, rather than later when the macros
2815 (downcase, upcase1): New static inline functions.
2816 (DOWNCASE, UPCASE1): Reimplement using these functions.
2817 This avoids undefined behavior in expressions like
2818 DOWNCASE (x) == DOWNCASE (y), which previously suffered
2819 from race conditions in accessing the global variables
2820 case_temp1 and case_temp2.
2821 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
2822 * lisp.h (case_temp1, case_temp2): Remove their decls.

2832 (file_name_as_directory): Use const pointers when appropriate.
2833 (Fexpand_file_name): Likewise. In particular, newdir might
2834 point at constant storage, so make it a const pointer.
2835 (Fmake_directory_internal, Fread_file_name): Remove unused vars.

2858 * buffer.c (fix_overlays_before): Mark locals as initialized.
2859 (fix_start_end_in_overlays): Likewise. This function should be

2863 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
2864 (report_overlay_modification): Rename locals to avoid shadowing.

2869 to suppress a gcc -Wclobbered warning that does not seem to be right.
2870 (MAXPATHLEN): Define only if needed.
2872 * process.c (serial_open, serial_configure): Move decls from here ...
2873 * systty.h: ... to here, so that they can be checked.
2875 * fns.c (get_random, seed_random): Move extern decls from here ...

2878 * sysdep.c (reset_io): Now static.
