(Fmemory_full_p): Function deleted.
(syms_of_alloc): Don't defsubr it.
(memory_full_cons_threshold): New variable.
(spare_memory): Now a vector of 7 elts.
(buffer_memory_full): Don't set Vmemory_full here.
(xfree): Don't try to refill here.
(emacs_blocked_free): Record BYTES_USED in local var.
(memory_full): Now free all the slots in spare_memory.
(refill_memory_reserve): Allocate each slot in spare_memory.
(init_alloc_once): Call refill_memory_reserve.
(gc_cons_combined_threshold): Var deleted.
(gc_relative_threshold): New variable.
(Fgarbage_collect, init_alloc_once): Compute gc_relative_threshold
instead of gc_cons_combined_threshold.
(overrun_check_malloc, overrun_check_realloc): Only add
overhead and write check pattern if check_depth is 1 (to handle
recursive calls). Increase/decrease check_depth in entry/exit.
(overrun_check_free): Only check for overhead if check_depth is 1.
Increase/decrease check_depth in entry/exit.
Call that at the very start.
(undo_limit, undo_strong_limit, undo_outer_limit): To undo.c.
(syms_of_alloc): Don't define undo-limit,
undo-strong-limit and undo-outer-limit here.
(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.
(XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): New macros to handle
sizeof(size_t) != 4.
(overrun_check_malloc, overrun_check_realloc, overrun_check_free):
Use them. Also clear header and trailer of freed memory.
(GC_STRING_OVERRUN_COOKIE_SIZE): Rename from GC_STRING_EXTRA.
(string_overrun_cookie): Rename from string_overrun_pattern.
(GC_STRING_EXTRA): Define from GC_STRING_OVERRUN_COOKIE_SIZE.
(marker_blocks_pending_free): Remove.
(Fgarbage_collect): Sweep after cleaning up undo-lists.
Mark the undo lists after claning them up.
Don't free block in marker_blocks_pending_free.
(mark_buffer): Don't mark undo_list.
(gc_sweep): Sweep hash-tables and strings first.
Do free marker blocks that are empty.
(Fgarbage_collect): Clear out buffer undo_list markers after gc_sweep.
Identify those markers as Lisp_Misc_Free objects. Clear car and cdr of
the removed cons cells.
(mark_object): Undo previous change - disallow Lisp_Misc_Free objects.
(gc_sweep): Clear cons_blocks before sweeping strings, so we don't have
any cons cells pointing to unallocated stings.
Do not lisp_free any marker blocks, as there may still be pointers
to them from buffer undo lists at this stage of GC.
