Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
(__malloc_size_t): Default to size_t, not to int.
(pure_size, pure_bytes_used_before_overflow, stack_copy_size)
(Fgarbage_collect, mark_object_loop_halt, mark_object):
Prefer ptrdiff_t to size_t when either would do, as we prefer
signed integers.
(XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
(xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
Now const. Initialize with values that are in range even if char
is signed.
(XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
(xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
These functions do the right thing with sizes > 2**32.
(check_depth): Now ptrdiff_t, not int.
(overrun_check_malloc, overrun_check_realloc, overrun_check_free):
Adjust to new way of storing sizes. Check for size overflow bugs
in rest of code.
(STRING_BYTES_MAX): Adjust to new overheads. The old code was
slightly wrong anyway, as it missed one instance of
XMALLOC_OVERRUN_CHECK_OVERHEAD.
(refill_memory_reserve): Omit needless cast to size_t.
(mark_object_loop_halt): Mark as externally visible.
(Fx_register_dnd_atom, x_handle_dnd_message):
Use ptrdiff_t, not size_t, since we prefer signed.
(Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
* xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
x_dnd_atoms_size and x_dnd_atoms_length.
* eval.c (verror):
* doprnt.c (doprnt):
* lisp.h (doprnt):
* xdisp.c (vmessage):
Use ptrdiff_t, not size_t, when using or implementing doprnt,
since the sizes cannot exceed ptrdiff_t bounds anyway, and we
prefer signed arithmetic to avoid comparison confusion.
* doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
but is a bit tricky.
* buffer.c (clone_per_buffer_values): Don't assume that
sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
This isn't true in general, and it's particularly not true
if Emacs is configured with --with-wide-int.
* buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
New macros, used in the buffer.c change.
* configure.in (HAVE_GCONF): Allow both HAVE_GCONF and HAVE_GSETTINGS.
* lisp/dynamic-setting.el (dynamic-setting-handle-config-changed-event):
Update doc string.
* src/xsettings.c: Use both GConf and GSettings if both are available.

(dpyinfo_valid, store_font_name_changed, map_tool_bar_style)
(store_tool_bar_style_changed): New functions.
(store_monospaced_changed): Add comment. Call dpyinfo_valid.
(struct xsettings): Move font inside HAVE_XFT.
(GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
(GSETTINGS_MONO_FONT): Renamed from SYSTEM_MONO_FONT.
Move inside HAVE_XFT.
(something_changed_gsettingsCB): Renamed from something_changedCB.
Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME
also.
(GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.
(GCONF_MONO_FONT): Renamed from SYSTEM_MONO_FONT. Move inside HAVE_XFT.
(something_changed_gconfCB): Renamed from something_changedCB.
Check for changes in GCONF_TOOL_BAR_STYLE and GCONF_FONT_NAME also.
(parse_settings): Move check for font inside HAVE_XFT.
(read_settings, apply_xft_settings): Add comment.
(read_and_apply_settings): Add comment. Call map_tool_bar_style and
store_tool_bar_style_changed. Move check for font inside HAVE_XFT and
call store_font_name_changed.
(xft_settings_event): Add comment.
(init_gsettings): Add comment. Get values for GSETTINGS_TOOL_BAR_STYLE
and GSETTINGS_FONT_NAME. Move check for fonts within HAVE_XFT.
(init_gconf): Add comment. Get values for GCONF_TOOL_BAR_STYLE
and GCONF_FONT_NAME. Move check for fonts within HAVE_XFT.
(xsettings_initialize): Call init_gsettings last.
(xsettings_get_system_font, xsettings_get_system_normal_font): Add
comment.
Assume support for memcmp, memcpy, memmove, memset.
This simplifies the code a bit. All current platforms have these,
as they are required for C89. If this turns into a problem we
can add the gnulib modules for these (a 1-line change to Makefile.in).
* configure.in: Don't check for memcmp, memcpy, memmove, memset.
[lib-src/ChangeLog]
Assume support for memcmp, memcpy, memmove, memset.
* etags.c (absolute_filename): Assume memmove exists.
[src/ChangeLog]
Assume support for memcmp, memcpy, memmove, memset.
* lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
* regex.c (memcmp, memcpy):
Remove; we assume C89 now.
* gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
(__malloc_safe_bcopy): Remove; no longer needed.
* fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
subseconds part to the entropy, as that's a bit more random.
Prefer signed to unsigned, since the signedness doesn't matter and
in general we prefer signed. When given a limit, use a
denominator equal to INTMASK + 1, not to VALMASK + 1, because the
latter isn't right if USE_2_TAGS_FOR_INTS.
* sysdep.c (get_random): Return a value in the range 0..INTMASK,
not 0..VALMASK. Don't discard "excess" bits that random () returns.
(syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
* w32fns.c (syms_of_w32fns):
* xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.
* gnutls.c (Fgnutls_boot): Don't mention :verify-error.
(syms_of_gnutls): Remove duplicate DEFSYM for
Qgnutls_bootprop_verify_hostname_error, an error for
Qgnutls_bootprop_verify_error (which is no longer used).
* eval.c (find_handler_clause): Remove parameters `sig' and `data',
unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
Also (re)move comments that are misplaced or no longer relevant.
* lisp/custom.el (custom-push-theme): Don't record faces in `changed'
theme; this doesn't work correctly for per-frame face settings.
(disable-theme): Use face-set-after-frame-default to reset faces.
(custom--frame-color-default): New function.
* lisp/frame.el (frame-background-mode, frame-set-background-mode):
Moved from faces.el.
(frame-default-terminal-background): New function.
* src/xfaces.c (Finternal_merge_in_global_face): Modify the foreground
and background color parameters if they have been changed.
* src/keymap.c (Fmake_composed_keymap): New function.
(Fset_keymap_parent): Simplify.
(fix_submap_inheritance): Remove.
(access_keymap_1): New function extracted from access_keymap to handle
embedded parents and handle lists of maps.
(access_keymap): Use it.
(Fkeymap_prompt, map_keymap_internal, map_keymap, store_in_keymap)
(Fcopy_keymap): Handle embedded parents.
(Fcommand_remapping, define_as_prefix): Simplify.
(Fkey_binding): Simplify.
(syms_of_keymap): Move minibuffer-local-completion-map,
minibuffer-local-filename-completion-map,
minibuffer-local-must-match-map, and
minibuffer-local-filename-must-match-map to Elisp.
(syms_of_keymap): Defsubr make-composed-keymap.
* src/keyboard.c (menu_bar_items): Use map_keymap_canonical.
(parse_menu_item): Trivial simplification.
* lisp/subr.el (remq): Don't allocate if it's not needed.
(keymap--menu-item-binding, keymap--menu-item-with-binding)
(keymap--merge-bindings): New functions.
(keymap-canonicalize): Use them to refine the canonicalization.
* lisp/minibuffer.el (minibuffer-local-completion-map)
(minibuffer-local-must-match-map): Move initialization from C.
(minibuffer-local-filename-completion-map): Move initialization from C;
don't inherit from anything here.
(minibuffer-local-filename-must-match-map): Make obsolete.
(completing-read-default): Use make-composed-keymap to combine
minibuffer-local-filename-completion-map with either
minibuffer-local-must-match-map or
minibuffer-local-filename-completion-map.
(wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
xg_select.
* xgselect.c: Add defined (HAVE_GSETTINGS).
(xgselect_initialize): Ditto.
* xsettings.c (store_monospaced_changed): Take new font as arg and
check for change against current_mono_font.
(EMACS_TYPE_SETTINGS): Remove this and related defines.
(emacs_settings_constructor, emacs_settings_get_property)
(emacs_settings_set_property, emacs_settings_class_init)
(emacs_settings_init, gsettings_obj): Remove.
(something_changedCB): New function for HAVE_GSETTINGS.
(something_changedCB): HAVE_GCONF: Call store_monospaced_changed
with value as argument.
(init_gsettings): Check that GSETTINGS_SCHEMA exists before calling
g_settings_new. Do not create gsettings_obj.
Remove calls to g_settings_bind. Connect something_changedCB to
"changed".
Fixes: debbugs:8967
Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
signed bit field, as this assumption is not portable and it makes
Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
"char debug_on_exit : 1" as this is not portable either; instead,
use the portable "unsigned int debug_on_exit : 1". Remove unused
member evalargs. Remove obsolete comments about cc bombing out.
* configure.in (gsettings): New option and check for GSettings.
* src/Makefile.in (SETTINGS_CFLAGS, SETTINGS_LIBS): Renamed from
GCONF_CFLAGS/LIBS.
* src/xsettings.c: Include glib.h if HAVE_GSETTINGS.
Let HAVE_GSETTINGS override HAVE_GCONF.

(EMACS_SETTINGS): A new type derived from GObject to handle
GSettings notifications.

(shrink_mini_window): Rename Qresize_root_window to
Qwindow_resize_root_window and Qresize_root_window_vertically to
Qwindow_resize_root_window_vertically.

respectively.
* buffer.c (Qclone_number): Declare static and DEFSYM it.
