Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.

On my host, this speeds up directory-files-and-attributes by a

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.

2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
Fix a race condition that causes Emacs to mess up glib (Bug#8855).
This is a backport from the trunk.
The symptom is a diagnostic "GLib-WARNING **: In call to
g_spawn_sync(), exit status of a child process was requested but
SIGCHLD action was set to SIG_IGN and ECHILD was received by
waitpid(), so exit status can't be returned." The diagnostic
is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
The real bug is a race condition between Emacs and glib: Emacs
does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
so that glib can't find it. Work around the bug by invoking
waitpid only on subprocesses that Emacs itself creates.
* src/process.c (create_process, record_child_status_change):
Don't use special value -1 in pid field, as the caller now must
know the pid rather than having the callee infer it. The
inference was sometimes incorrect anyway, due to another race.
(create_process): Set new 'alive' member if child is created.
(process_status_retrieved): New function.
(record_child_status_change): Use it.
Accept negative 1st argument, which means to wait for the
processes that Emacs already knows about. Move special-case code
for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
processes that have already been waited for, by testing and
clearing new 'alive' member.
(CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
now does this internally.
(handle_child_signal): Let record_child_status_change do all
the work, since we do not want to reap all exited child processes,
only the child processes that Emacs itself created.
* src/process.h (Lisp_Process): New boolean member 'alive'.
* admin/CPP-DEFINES (HAVE_CLOSEDIR, HAVE_DIRENT_H): Remove.
* admin/notes/copyright: Adjust to src/ndir.h -> nt/inc/dirent.h renaming.
* configure.ac: Do not check for dirent.h or closdir.
* nt/inc/dirent.h: Rename from ../src/ndir.h, with these changes:
(struct dirent): Rename from struct direct. All uses changed.
* nt/inc/sys/dir.h: Remove.
* src/dired.c: Assume HAVE_DIRENT_H.
(NAMLEN): Remove, replacing with ...
(dirent_namelen): New function. All uses changed. Use the GNU macro
_D_EXACT_NAMELEN if available, as it's faster than strlen.
(DIRENTRY): Remove, replacing all uses with 'struct dirent'.
(DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
* src/makefile.w32-in (DIR_H): Remove. All uses replaced with
$(NT_INC)/dirent.h.
($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
* src/ndir.h: Rename to ../nt/inc/dirent.h.
* src/sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
Do not include <dirent.h>; no longer needed.
* src/w32.c: Include <dirent.h> rather than "ndir.h".
Fixes: debbugs:12958
* admin/CPP-DEFINES (O_RDONLY, O_RDWR, HAVE_FCNTL_H): Remove.
* admin/merge-gnulib (GNULIB_MODULES): Add fcntl-h.
* configure.ac: Do not check for fcntl.h.
* lib/gnulib.mk: Regenerate.
* lib-src/movemail.c, lib-src/update-game-score.c: Assume <fcntl.h> exists.
* nt/inc/sys/socket.h (O_NONBLOCK): Rename from O_NDELAY, since the
POSIX name for this flag is O_NONBLOCK. All uses changed.
* nt/inc/unistd.h (O_RDWR, O_NOCTTY): New macros. Like AT_FDCWD etc.
these really should be moved to a replacement <fcntl.h> if and
when that gets implemented. In the meantime, include <fcntl.h>
to make sure we don't override its definitions.
* src/callproc.c (relocate_fd): Assume F_DUPFD.
* src/emacs.c, src/term.c (O_RDWR): Remove.
* src/keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
O_NDELAY, since O_NONBLOCK is the standard name for this flag.
* src/nsterm.m: Assume <fcntl.h> exists.
* src/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.
* src/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.
* src/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.
* src/w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.

src/xdisp.c (start_hourglass, cancel_hourglass): Now used on
WINDOWSNT as well.
(start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
src/w32.h (init_timers, term_timers): Add prototypes.
nt/inc/sys/time.h (ITIMER_REAL, ITIMER_PROF): Define.
(struct itimerval): Define.
(getitimer, setitimer): Add prototypes.
nt/inc/ms-w32.h <sigset_t> [_MSVC_VER]: Make the typedef consistent
with MinGW.
(SA_RESTART, SIGPROF): Define.
nt/config.nt (HAVE_SETITIMER): Define to 1.
src/w32.c: Include winioctl.h and aclapi.h.
(is_symlink, chase_symlinks, enable_privilege, restore_privilege)
(revert_to_self): Forward declarations of static functions.
<static BOOL g_b_init_get_security_info>:
<g_b_init_create_symbolic_link>: New static flags.
(globals_of_w32): Initialize them to zero.
(GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
(map_w32_filename): Improve commentary. Simplify switch.
(SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
headers (most versions of MinGW w32api don't).
(get_security_info, create_symbolic_link)
(get_file_security_desc_by_handle, is_symlink, chase_symlinks):
New functions.
(sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
in the argument file name.
(sys_access): Call unc_volume_file_attributes only if
GetFileAttributes fails with network-related error codes.
(sys_rename): Diagnose renaming of a symlink when the user doesn't
have the required privileges.
(get_file_security_desc_by_name): Renamed from
get_file_security_desc.
(stat_worker): New function, with most of the guts of 'stat', and
with addition of handling of symlinks and support for 'lstat'. If
possible, get file's attributes and security information by
handle, not by name. Produce S_IFLNK bit for symlinks, when
called from 'lstat'.
(stat, lstat): New functions, call 'stat_worker'.
(symlink, readlink, careadlinkat): Rewritten to create and resolve
symlinks when the underlying filesystem supports them.
lib/src/ntlib.c (lstat): New function, calls 'stat'.
nt/inc/sys/stat.h (S_IFLNK): Define.
(S_ISLNK): A non-trivial definition.
(lstat): Prototype instead of a macro that redirects to 'stat'.
lisp/files.el (file-truename): Don't skip symlink-chasing part on
windows-nt. Incorporate the resolution of 8+3 short aliases on
Windows into the loop that recursively chases symlinks. Compare
directory and its parent case-insensitively on MS-Windows and
MS-DOS.
etc/NEWS: Announce the symlink support on MS-Windows.

now defined in src/s/ms-w32.h.
