(READABLE_EVENTS_FILTER_EVENTS)
(READABLE_EVENTS_IGNORE_SQUEEZABLES): New flags for readable_events.
get_filtered_input_pending, readable_filtered_events): Removed.
(tracking_off): Call readable_events and get_input_pending with
flag READABLE_EVENTS_DO_TIMERS_NOW.
(readable_events): Move code from old readable_filtered_events here,
but check new READABLE_EVENTS_* in argument flags instead of previous
two boolean arguments do_timers_now and filter_events.
If we are doing mouse tracking and the mouse moved, return only if
READABLE_EVENTS_IGNORE_SQUEEZABLES is not set in flags.
(swallow_events): Call get_input_pending with flag
READABLE_EVENTS_DO_TIMERS_NOW.
(get_input_pending): Move code from old get_filtered_input_pending
here. Replace boolean arguments do_timers_now, filter_events with
flags, and pass flags to readable_events. Document new
READABLE_EVENTS_* flags.
(detect_input_pending_ignore_squeezables): New function.
(detect_input_pending_run_timers): Call get_input_pending with flag
READABLE_EVENTS_DO_TIMERS_NOW.
(Finput_pending_p): Call get_input_pending with flags
READABLE_EVENTS_DO_TIMERS_NOW and READABLE_EVENTS_FILTER_EVENTS.
* dispnew.c (update_window, update_frame_1): Replace calls to
detect_input_pending with detect_input_pending_ignore_squeezables
so that redisplay is not paused if the event queue contains only
mouse movements.
* lisp.h: Declare detect_input_pending_ignore_squeezables.
(xg_get_file_name): Block and unblock __SIGRTMIN if defined.
* alloc.c: If HAVE_GTK_AND_PTHREAD, include pthread.h,
new variables main_thread and alloc_mutex,
define (UN)BLOCK_INPUT_ALLOC to use alloc_mutex to protect
emacs_blocked_* calls and only do (UN)BLOCK_INPUT in the main thread.
If not HAVE_GTK_AND_PTHREAD, (UN)BLOCK_INPUT_ALLOC is the same as
(UN)BLOCK_INPUT.
(emacs_blocked_free, emacs_blocked_malloc)
(emacs_blocked_realloc): Use (UN)BLOCK_INPUT_ALLOC.
(uninterrupt_malloc): Initialize main_thread and alloc_mutex.
(reset_malloc_hooks): New function.
* lisp.h: Declare reset_malloc_hooks.
* emacs.c (Fdump_emacs): Call reset_malloc_hooks.
* keyboard.c: Conditionally include pthread.h
(handle_async_inpu, input_available_signalt): If not in the main
thread, block signal, send signal to main thread and return.
Fx_file_dialog if only directories should be read.
* lisp.h: Fx_file_dialog takes 5 parameters.
* xfns.c (Fx_file_dialog): Both Motif and GTK version: Add
parameter only_dir_p.
In Motif version, don't put DEFAULT_FILENAME in filter part of the
dialog, just text field part. Do not add DEFAULT_FILENAME
to list of files if it isn't there.
In GTK version, pass only_dir_p parameter to xg_get_file_name.
* macfns.c (Fx_file_dialog): Add parameter only_dir_p. Check
only_dir_p instead of comparing prompt to "Dired". When using
a save dialog, add option kNavDontConfirmReplacement, change title
to "Enter name", change text for save button to "Ok".
* w32fns.c (Fx_file_dialog): Add parameter only_dir_p. Check
only_dir_p instead of comparing prompt to "Dired".
* gtkutil.c (xg_get_file_with_chooser)
(xg_get_file_with_selection): New functions, only defined ifdef
HAVE_GTK_FILE_CHOOSER_DIALOG_NEW and HAVE_GTK_FILE_SELECTION_NEW
respectively.
(xg_get_file_name): Add parameter only_dir_p.
Call xg_get_file_with_chooser or xg_get_file_with_selection
depending on HAVE_GTK_FILE* and the value of use_old_gtk_file_dialog.
(xg_initialize): New DEFVAR_BOOL use_old_gtk_file_dialog.
* gtkutil.h (xg_get_file_name): Add parameter only_dir_p.
(SAFE_ALLOCA, SAFE_ALLOCA_LISP): Increment it when malloc is used.
(SAFE_FREE): Test it to determine if we need to unwind to free.
Remove size arg. All users changed.
(SAFE_FREE_LISP) Remove. All users changed to use SAFE_FREE.
(SAFE_ALLOCA_LISP): Change second arg to number of elements.
Set dogc member in Lisp_Save_Value object so it will be GC'ed.
(SAFE_FREE_LISP): New macro.
