src/systhread.h (w32thread_critsect, w32thread_cond_t, sys_mutex_t)
(sys_cond_t, sys_thread_t) [WINDOWSNT]: New data types.
src/systhread.c (sys_mutex_init, sys_mutex_lock, sys_mutex_unlock)
(sys_mutex_destroy, sys_cond_init, sys_cond_wait)
(sys_cond_signal, sys_cond_broadcast, sys_cond_destroy)
(sys_thread_self, sys_thread_equal, w32_beginthread_wrapper)
(sys_thread_create, sys_thread_yield) [WINDOWSNT]: New functions.
configure.ac (THREADS_ENABLED): Enable threads for MinGW, even
if pthreads is not available.
src/callproc.c:
src/emacs.c:
src/filelock.c:
src/process.c:
src/sysdep.c:
src/w32.c: Reshuffle Windows-specific headers to avoid errors with
redefinition of fd_set etc.
src/process.c: Don't use num_pending_connects when
NON_BLOCKING_CONNECT is not defined.
src/sysselect.h: Move definitions of FD_* macros and of SELECT_TYPE
here from w32.h.
src/w32proc.c (sys_select): Adjust the argument types to what
thread.h expects.
nt/inc/sys/socket.h: Include stdint.h. Include sysselect.h instead
of w32.h.
src/xdisp.c (get_next_display_element): Don't apply to characters
from a display vector the logic of setting it->end_of_box_run_p
suitable for characters from a buffer.
* process.c (Fset_process_window_size): Signal an error if
the window size is outside the range supported by the lower level.
* sysdep.c (set_window_size): Return negative on error,
nonnegative on success, rather than -1, 0, 1 on not in system,
failure, success. This is simpler. Caller changed.
(serial_configure): Remove unnecessary initialization of local.
(procfs_get_total_memory) [GNU_LINUX]: Don't assume system memory
size fits in unsigned long; this isn't true on some 32-bit hosts.
Avoid buffer overrun if some future version of /proc/meminfo has a
variable name longer than 20 bytes.
(system_process_attributes) [__FreeBSD__]:
Don't assume hw.availpages fits in 'int'.
Fix some related minor problems involving "//", vfork.
* callproc.c (encode_current_directory): New function.
(call_process): Don't append "/"; not needed.
* fileio.c (file_name_as_directory_slop): New constant.
(file_name_as_directory): Allow SRC to be longer than SRCLEN;
this can save the caller having to alloca.
(Ffile_name_as_directory, Fdirectory_file_name, Fexpand_file_name):
Use SAFE_ALLOCA, not alloca.
(directory_file_name, Fexpand_file_name): Leave leading "//"
alone, since it can be special even on POSIX platforms.
* callproc.c (call_process):
* process.c (Fformat_network_address):
* sysdep.c (sys_subshell):
Use encode_current_directory rather than rolling our own.
(create_process): No need to encode directory; caller does that now.
* process.h (encode_current_directory): New decl.
* sysdep.c (sys_subshell): Work even if vfork trashes saved_handlers.
Rework to avoid 'goto xyzzy;'.
(call_process): New arg TEMPFILE_INDEX. Callers changed.
Record deleted process-id in critical section, not afterwards.
Don't mistakenly kill process created by a call-process invocation
that discards output and does not wait.
Fixes: debbugs:15144
and GC_MARK_STACK == GC_USE_GCPROS_CHECK_ZOMBIES.
* alloc.c (toplevel): Remove unnecessary nested #if...#endif.
(mark_maybe_object) [!GC_MARK_STACK]: Define to emacs_abort
to shut up compiler in mark_object.
(dump_zombies): Convert to global and add EXTERNALLY_VISIBLE.
(struct animation_cache): Make signature a flexible array member.
All uses changed. This is a tad slower but may insulate us better
from future changes to ImageMagick.
(SIGNATURE_DIGESTSIZE): New constant.
(struct animation_cache): Make 'signature' a fixed size array of bytes.
(imagemagick_create_cache): Copy the signature. This saves
several KB of memory that ImageMagick wastes per signature.
Don't bother updating the update_time, as the caller does that now.
(imagemagick_prune_animation_cache): Don't destroy the signature, as
it's a fixed size struct member now.
(imagemagick_get_animation_cache): Always destroy the signature,
as it's now imagemagick_create_cache's responsibility to copy it.
Avoid duplicate calls to strcmp and to imagemagick_create_cache,
and use memcmp rather than strcmp.
eassert that ImageMagick returns a signature of the specified length.
Fix some other minor performance problems while we're at it.
(imagemagick_create_cache): Clear just the members that
need clearing. Don't set update_time, as caller does that now.
(imagemagick_prune_animation_cache, imagemagick_get_animation_cache):
Simplify by using pointer-to-pointer instead of a prev pointer.
(imagemagick_prune_animation_cache): Use make_emacs_time rather
than EMACS_TIME_FROM_DOUBLE, and DestroyString rather than free.
(imagemagick_get_animation_cache): Don't xstrdup the image signature;
it's already a copy. Free the signature probe unless it's cached.
* src/sheap.c (STATIC_HEAP_SIZE): Adjust to current needs; use bigger
static heap if ENABLE_CHECKING is defined.
(max_bss_sbrk_ptr): New variable.
(bss_sbrk): Use it.
(report_sheap_usage): Report maximum static heap usage instead of
ending static heap usage.
