	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

2012-11-07  Eli Zaretskii  <eliz@gnu.org>

154 155 156
	* w32fns.c (modifier_set): Don't report modifiers from toggle key,
	such as Scroll Lock, if the respective keys are treated as
	function keys, not as modifiers.  This avoids destroying non-ASCII
157
	keyboard input when Scroll Lock is toggled ON.  (Bug#12806)

2012-11-06  Paul Eggert  <eggert@cs.ucla.edu>

	Restore some duplicate definitions (Bug#12814).
	This undoes part of the 2012-11-03 changes.  Some people build
	with plain -g rather than with -g3, and they need the duplicate
	definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
	* lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
	Define as macros, as well as as enums or as constants.

2012-11-06  Paul Eggert  <eggert@cs.ucla.edu>

	Minor adjustments of recently-changed frame functions.
	* buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
	known to be a frame (we're in the FRAMEP branch).
	* lisp.h (Qframep): Remove decl.  frame.h declares this.
	* window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
	since they're meant for Lisp fixnum values.

	* w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
245
	(emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use

	Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
	This removes code that has been obsolete since around 1990.
	* callproc.c (Fcall_process):
	* emacs.c (main):
	* process.c (create_process):
	* term.c (dissociate_if_controlling_tty):
	Assume setsid exists.
	* callproc.c (child_setup): Assume setpgid exists and behaves as
	per POSIX.1-1988 or later.
	* conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
	* emacs.c (shut_down_emacs):
	* sysdep.c (sys_suspend, init_foreground_group):
	Assume getpgrp behaves as per POSIX.1-1998 or later.
	* msdos.c (setpgrp): Remove.
	(tcgetpgrp, setpgid, setsid): New functions.
	* systty.h (EMACS_GETPGRP): Remove.  All callers now use getpgrp.
	* term.c (no_controlling_tty): Remove; unused.

	Remove EMACS_OUTQSIZE+sleep hack.
	* dispnew.c (update_frame_1): Remove hack for terminals slower
283 284
	than 2400 bps, which throttled Emacs by having it sleep.
	This code hasn't worked since at least 2007, when the multi-tty stuff
285 286 287 288
	was added, and anyway those old terminals are long dead.
	* systty.h (EMACS_OUTQSIZE): Remove; unused.  The macro isn't used even
	without the dispnew.c change, as dispnew.c doesn't include systty.h.

289 290 291 292 293 294 295
	Fix data-loss with --version (Bug#9574).
	* emacs.c (close_output_streams): Use strerror, not emacs_strerror,
	as we can't assume that emacs_strerror is initialized, and strerror
	is good enough here.
	(main): Invoke atexit earlier, to catch earlier instances of
	sending data to stdout and exiting, e.g., "emacs --version >/dev/full".

	Fix data-loss with --batch (Bug#9574).
	* emacs.c: Include <close-stream.h>.
	(close_output_streams): New function.
	(main): Pass it to atexit, so that Emacs closes stdout and stderr
	and handles errors appropriately.
	(Fkill_emacs): Don't worry about flushing, as close_output_stream
	does that now.

311 312 313 314 315 316 317 318 319 320 321 322
	Fix a race condition that causes Emacs to mess up glib (Bug#8855).
	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.
	* process.c (create_process, record_child_status_change):
	Don't use special value -1 in pid field, as the caller now must
323 324
	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.
	* process.h (Lisp_Process): New boolean member 'alive'.

340 341 342 343 344 345 346
	Omit duplicate definitions no longer needed with gcc -g3.
	* lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
	(VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
	Define only as macros.  There's no longer any need to also define
	these symbols as enums or as constants, since we now assume
	gcc -g3 when debugging.

	* lisp.mk: Adjust comments to the fact that term/internal is now
	loaded from loadup.el.

	* msdos.c (msdos_abort): Rename from emacs_abort, and make static.
	(msdos_fatal_signal): New function.
	(XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
	its argument list.

	* conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
	for GCC versions before 4.
	(emacs_raise): Define to call msdos_fatal_signal.

	iterator when starting in the middle of a display or overlay
	string.  (Bug#12745)

	Port to OpenBSD 5.1.
	* frame.c (Fmouse_position, Fmouse_pixel_position):

	Declare local vars only when they're needed.

	This is safer, and avoids OpenBSD warnings about unused vars.
	* keyboard.c (record_menu_key): Remove unnecessary decl.
	(poll_timer): Define only if POLL_FOR_INPUT is defined.
	* unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,

	Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
	merely Lisp_Object *.  This is more informative and avoids
	a warning on OpenBSD about accessing beyond an object's size.

	* conf_post.h:
	(_DebPrint) declare tracing facility for W32 debugging.  We need
	to unify tracing later.

	(NTGUI_UNICODE) Define when compiling for Cygwin to allow the
	unconditional use of W32 Unicode functions.  Cygwin runs only on
	100% Unicode operating systems.

	* cygw32.c: New file.  Define Cygwin-specific facilities.
	(Fcygwin_convert_path_to_windows)
	(Fcygwin_convert_path_from_windows): New user functions for
	accessing Cygwin path-munging routines.

	* cygw32.h: New file.
	(WCSDATA, to_unicode, from_unicode): Define facilities for storing
	UTF-16LE strings temporarily inside non-Lisp-visible string
	objects.

	(w32_strerror): Just what it says on the tin.

	* emacs.c: Make the NS fork-then-exec code for daemon-launching
	also run for Cygwin; both systems have the same problem with using
	GUI facilities in a forked child.  Also call syms_of_cygw32,
	syms_of_w32select in correct places.

	(DAEMON_MUST_EXEC): new macro defined to signal that a platform
	needs fork-then-exec for daemon launching.

	* font.h: Include frame.h.

	* image.c: Use the image library cache machinery only when we're
	compiling for native WINDOWSNT; Cygwin can use shared libraries
	like any other Unixlike system.

	* keyboard.c: Clarify a comment regarding the input loop.

	* menu.c: When NTGUI_UNICODE is defined, use Unicode menu
	functions directly instead of trying to detect at runtime that our
	host operating system supports them.  We make this change for two
	reasons: Cygwin lacks support for the multibyte character
	conversion functions used by the legacy menu code, and Cygwin
	never needs to rely on non-Unicode APIs.

	* unexw32.c (hinst): Declare extern.

	* w32.c: Change header order;
	(w32_strerror): Move to w32fns.c because we need it for
	non-WINDOWSNT builds.

	* w32.h: Add #error macro to make sure we don't include w32.h for

	(w32_createwindow): Unconditionally call w32_init_class instead of
	doing so only when hprevinst is non-NULL.  Plumbing hprevinst
	through the code is complex and unnecessary because class
	registration is practically free.
	(w32_name_of_message): New EMACSDEBUG-only function.
	(Fset_message_beep): Move here
	(Fx_open_connection): Require that the display name for Windows be
	"w32" for consistency, emacsclient disambiguation, and maybe, one

	(file_dialog_callback): NTGUI_UNICODE changes; encode and decode
	Cygwin files for W32 GUI facilities, since these clearly don't
	expect Cygwin names.
	(_DebPrint): Define.

	(w32_message_fd): New variable.  Under Cygwin, holds the file
	descriptor the system used to tell us about pending thread
	messages.

	setting the input event directly.

	(min): Define only if not already defined.

	* frame.c (x_report_frame_params): Use EMACS_UINT for the return
	value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows
	hosts.

	* image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since
	'bitmaps' is a pointer.

	* dispextern.h (x_bitmap_pixmap): Adjust prototype.

	* alloc.c (gdb_make_enums_visible): Now conditional on __GNUC__.
