+2012-11-18  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
+
+2012-11-18  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32select.c: Include w32common.h before w32term.h, so that
+        windows.h gets included before w32term.h uses some of its
+        features, see below.
+
+        * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
+        typedefs.
+        (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
+        prototypes.
+        (EnumSystemLocales) [_MSC_VER]: Define if undefined.  (Bug#12878)
+
+2012-11-18  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
+        (ns_select): Return at once if events are held (Bug#12834).

+
+        * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
+        Needed following 2012-10-20 change.  (Bug#12902)
+
+2012-11-18  Juanma Barranquero  <lekktu@gmail.com>
+
+        * w32proc.c (waitpid): Remove unused label get_result.
+
+2012-11-17  Juanma Barranquero  <lekktu@gmail.com>
+
+        * makefile.w32-in (SYSWAIT_H): New macro.
+        ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
+        ($(BLD)/sysdep.$(O)): Update dependencies.
+
+2012-11-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+        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.
+        * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
+        O_NDELAY, since O_NONBLOCK is the standard name for this flag.
+        * nsterm.m: Assume <fcntl.h> exists.
+        * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
+        (create_pty, Fmake_network_process, server_accept_connection)
+        (wait_reading_process_output, init_process_emacs):
+        Assume O_NONBLOCK.
+        (wait_reading_process_output): Put in a special case for WINDOWSNT
+        to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
+        It's not clear this is needed, but it's a more-conservative change.
+        (create_process): Assume FD_CLOEXEC.
+        (create_process, create_pty): Assume O_NOCTTY.
+        * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
+        (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
+        Omit if not DOS_NT, since F_GETFL is not defined there.
+        (serial_open): Assume O_NONBLOCK and O_NOCTTY.
+        * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
+        (O_NOCTTY): Remove.
+        (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
+        lack it, since gnulib guarantees this.
+        * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
+
+2012-11-17  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (faccessat): Pretend that directories have the execute bit
+        set.  Emacs expects that, e.g., in files.el:cd-absolute.
+
+        * w32proc.c (create_child): Don't clip the PID of the child
+        process to fit into an Emacs integer, as this is no longer a
+        restriction.
+        (waitpid): Rename from sys_wait.  Emulate a Posix 'waitpid' by
+        reaping only the process specified by PID argument, if that is
+        positive.  Use PID instead of dead_child to know which process to
+        reap.  Wait for the child to die only if WNOHANG is not in
+        OPTIONS.
+        (sys_select): Don't set dead_child.
+
+        * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
+        as it is no longer needed.
+
+        * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
+        no longer needed.
+        (record_child_status_change): Remove the setting of
+        record_at_most_one_child for the !WNOHANG case.
+
+2012-11-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Fix problems in ns port found by static checking.
+        * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
+        (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
+        not to process group.
+        (ns_select): Use emacs_write, not write, as that's more robust
+        in the presence of signals.
+        (fd_handler:): Check for read errors.
+
+2012-11-16  Glenn Morris  <rgm@gnu.org>
+
+        * editfns.c (Fmessage): Mention message-log-max.  (Bug#12849)
+
+2012-11-16  Stefan Monnier  <monnier@iro.umontreal.ca>
+
+        * eval.c (Finteractive_p): Revert lexbind-merge mishap.
+
+2012-11-16  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
+        use the same value of thread handle.
+        (start_timer_thread): If the timer thread exited (due to error),
+        clean up by closing the two handles it used.  Duplicate the caller
+        thread's handle here, so it gets duplicated only once, when
+        launching the timer thread.  Set priority of the timer thread, not
+        the caller thread.
+        (getitimer): Don't duplicate the caller thread's handle here.
+        (Bug#12832)
+
+2012-11-16  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
+        called (Bug#12834).
+
+2012-11-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Remove no-longer-used pty_max_bytes variable.
+        * process.c (pty_max_bytes): Remove; unused.
+        (send_process): Do not set it.
+
+2012-11-15  Juanma Barranquero  <lekktu@gmail.com>
+
+        * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
+        Update dependencies.
+
+2012-11-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
+        This follows up on the 2012-09-29 patch that removed indirection
+        for the 'function' field.  Reported by Sergey Vinokurov in
+        <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
+
+2012-11-14  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32.c (faccessat): Rename from sys_faccessat.  (No need to use a
+        different name, as the MS runtime does not have such a function,
+        and probably never will.)  All callers changed.  Ignore DIRFD
+        value if PATH is an absolute file name, to match Posix spec
+        better.  If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
+        symlinks.
+
+2012-11-14  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * xdisp.c (echo_area_display, redisplay_internal):
+        Omit redundant check whether frame_garbaged is set.
+
+2012-11-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+        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.
+        * Makefile.in (LIB_EACCESS): New macro.
+        (LIBES): Use it.
+        * callproc.c (init_callproc):
+        * charset.c (init_charset):
+        * fileio.c (check_existing, check_executable, check_writable)
+        (Ffile_readable_p):
+        * lread.c (openp, load_path_check):
+        * process.c (allocate_pty):
+        * xrdb.c (file_p):
+        Use effective UID when checking permissions, not real UID.
+        * callproc.c (init_callproc):
+        * charset.c (init_charset):
+        * lread.c (load_path_check, init_lread):
+        Test whether directories are accessible, not merely whether they exist.
+        * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
+        * 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.
+        * dispnew.c (glyphs_initialized_initially_p): Remove.
+        (adjust_frame_glyphs_initially): Likewise.  Adjust users.
+        (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
