+ Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
+ * callproc.c (relocate_fd): Assume F_DUPFD.
+ * emacs.c, term.c (O_RDWR): Remove.

+ (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by

+
+ Use faccessat, not access, when checking file permissions (Bug#12632).
+ This fixes a bug that has been present in Emacs since its creation.
+ It was reported by Chris Torek in 1983 even before GNU Emacs existed,
+ which must set some sort of record. (Torek's bug report was against
+ a predecessor of GNU Emacs, but GNU Emacs happened to have the
+ same common flaw.) See Torek's Usenet posting
+ "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
+ Posted: Fri Apr 8 14:18:56 1983.

+ * fileio.c (check_existing, check_executable, check_writable)
+ (Ffile_readable_p):
+ Use symbolic names instead of integers for the flags, as they're
+ portable now.
+ (check_writable): New arg AMODE. All uses changed.
+ Set errno on failure.
+ (Ffile_readable_p): Use faccessat, not stat + open + close.
+ (Ffile_writable_p): No need to call check_existing + check_writable.
+ Just call check_writable and then look at errno. This saves a syscall.
+ dir should never be nil; replace an unnecessary runtime check
+ with an eassert. When checking the parent directory of a nonexistent
+ file, check that the directory is searchable as well as writable, as
+ we can't create files in unsearchable directories.
+ (file_directory_p): New function, which uses 'stat' on most platforms
+ but faccessat with D_OK (for efficiency) if WINDOWSNT.
+ (Ffile_directory_p, Fset_file_times): Use it.
+ (file_accessible_directory_p): New function, which uses a single
+ syscall for efficiency.
+ (Ffile_accessible_directory_p): Use it.
+ * xrdb.c (file_p): Use file_directory_p.
+ * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
+ * lread.c (openp): When opening a file, use fstat rather than
+ stat, as that avoids a permissions race. When not opening a file,
+ use file_directory_p rather than stat.
+ (dir_warning): First arg is now a usage string, not a format.
+ Use errno. All uses changed.
+ * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
+ that merely introduced a race.
+ * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
+ changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
+ and similarly for the other O_* flags.
+ * w32.c (sys_faccessat): Rename from sys_access and switch to
+ faccessat's API. All uses changed.
+ * xrdb.c: Do not include <sys/stat.h>; no longer needed.
+ (magic_db): Rename from magic_file_p.
+ (magic_db, search_magic_path): Return an XrmDatabase rather than a
+ char *, so that we don't have to test for file existence
+ separately from opening the file for reading. This removes a race
+ fixes a permission-checking problem, and simplifies the code.
+ All uses changed.
+ (file_p): Remove; no longer needed.
+
+2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
+
+ Omit glyphs initialization at startup.

+ (Fredraw_frame): Move actual code from here...
+ (redraw_frame): ...to here. Add eassert. Adjust comment.
+ (Fredraw_display): Use redraw_frame.
+ * xdisp.c (clear_garbaged_frames): Likewise.
+
+2012-11-13 Eli Zaretskii <eliz@gnu.org>
+
+ * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
+ passed to pint2str and pint2hrstr to be at most the size of the
+ frame's decode_mode_spec_buffer. This avoids crashes with very
+ large values of FIELD_WIDTH argument to decode_mode_spec.
+ (Bug#12867)
+
+2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix a race with verify-visited-file-modtime (Bug#12863).
+ Since at least 1991 Emacs has ignored an mtime difference of no
+ more than one second, but my guess is that this was to work around
+ file system bugs that were fixed long ago. Since the race is
+ causing problems now, let's remove that code.
+ * fileio.c (Fverify_visited_file_modtime): Do not accept a file
+ whose time stamp is off by no more than a second. Insist that the
+ file time stamps match exactly.
+
+2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
+
+ * frame.h (struct frame): Convert external_tool_bar member to
+ 1-bit unsigned bitfield.
+ * termhooks.h (struct terminal): Remove mouse_moved member since
+ all users are long dead. Adjust comment on mouse_position_hook.
+
+2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
+
+ Simplify by using FOR_EACH_FRAME here and there.
+ * frame.c (next_frame, prev_frame, other_visible_frames)

+ * xselect.c (frame_for_x_selection): Likewise.
+ * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
+ (x_window_to_menu_bar): Likewise.
+ * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
+
+2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data.c (Qdefalias_fset_function): Now static.
+
+ Another tweak to vectorlike_header change.
+ * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
+ Remove, and replace all uses with ...
+ (next_in_free_list, set_next_in_free_list):
+ New functions, which respect C's aliasing rules better.
+
+2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * window.c (list4i): Rename from 'quad'. All uses changed.
+ Needed because <sys/types.h> defines 'quad' on Solaris 10.
+
+2012-11-11 Juanma Barranquero <lekktu@gmail.com>
+
+ * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
+ warning about mixing declarations and code in ISO C90.
+
+2012-11-10 Martin Rudalics <rudalics@gmx.at>
+
+ * window.c (Fsplit_window_internal): Set combination limit of
+ new parent window to t iff Vwindow_combination_limit is t;
+ fixing a regression introduced with the change from 2012-09-22.
+ (Fset_window_combination_limit): Fix doc-string.
+
+2012-11-10 Eli Zaretskii <eliz@gnu.org>
+
+ * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
+ amount when the scroll margins are too large. When scrolling
+ backwards in the buffer, give up if cannot reach point or the
+ scroll margin within a reasonable number of screen lines. Fixes
+ point position in window under scroll-up/down-aggressively when
+ point is positioned many lines beyond the window top/bottom.
+ (Bug#12811)
+
+ * ralloc.c (relinquish): If real_morecore fails to return memory
+ to the system, don't crash; instead, leave the last heap
+ unchanged and return. (Bug#12774)
+
+2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
+
+ * lisp.h (AUTOLOADP): New macro.

+
+2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
+
+ Fix recently introduced crash on MS-Windows (Bug#12839).
+ * w32term.h (struct scroll_bar): Use convenient header.
+ (SCROLL_BAR_VEC_SIZE): Remove.
+ * w32term.c (x_scroll_bar_create): Use VECSIZE.
+
+2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
+
+ Tweak last vectorlike_header change.
+ * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
+ vectorlike object on the free list. This is introduced to avoid
+ some (but not all) pointer casting and aliasing problems, see
+ http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
+ * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
