809 810 811 812 813 814 815
	Simplify SELECT_TYPE-related code.

	Simplify EMACS_TIME-related code.
	This portability layer is no longer needed, since Emacs has been
	using struct timespec as a portability layer for some time.

	Fix unlikely core dump in init_tty, and simplify terminfo case.
	* term.c (init_tty) [TERMINFO]: Fix check for buffer overrun.
	The old version incorrectly dumped core if malloc returned a
	buffer containing only non-NUL bytes.
	(init_tty): Do not allocate or free termcap buffers; the
	struct does that for us now.
	* termchar.h (TERMCAP_BUFFER_SIZE) [!TERMINFO]: New constant.
	(struct tty_display_info): Define members termcap_term_buffer and
	termcap_strings_buffer only if !TERMINFO, since terminfo doesn't
	use them.  Allocate them directly in struct rather than indirectly
	via a pointer, to simplify init_tty.

907 908 909
	* frame.c (check_minibuf_window): Initialize 'window' properly,
	so that Emacs reliably aborts later if 'window' is not initialized.

910 911 912 913 914
2013-08-26  Jan Djärv  <jan.h.d@swipnet.se>

2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

	* window.h (struct window): Replace last_cursor with last_cursor_vpos

937 938
2013-08-26  Dmitry Antipov  <dmantipov@yandex.ru>

939 940
	Fix recovering from possible decompression error.
	Since insert_from_gap doesn't always move point, we can't use PT as
941
	the position where the partially decompressed data ends, and
Dmitry Antipov's avatar
Dmitry Antipov committed
942
	should count how many bytes was produced so far.
943 944 945 946
	* decompress.c (struct decompress_unwind_data): Add nbytes member.
	(unwind_decompress): Really delete partially uncompressed data.

	suitable for characters from a buffer.  (Bug#15175)

963 964 965 966
	* w32.c (fdutimens): Call 'utime', which is implemented on w32.c
	to handle directories, rather than '_utime' which doesn't.

	System-dependent integer overflow fixes.
	* 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'.

	(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.

	* process.h (encode_current_directory): New decl.
	* sysdep.c (sys_subshell): Work even if vfork trashes saved_handlers.

	* process.c (allocate_pty) [PTY_OPEN]: Set fd's FD_CLOEXEC flag.
	We can't portably rely on PTY_OPEN doing that, even if
	it calls posix_openpt with O_CLOEXEC.

	(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.

	* image.c: Fix animation cache signature memory leak.
	Fix some other minor performance problems while we're at it.
	(imagemagick_create_cache): Clear just the members that

	(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

	(imagemagick_get_animation_cache): Don't xstrdup the image signature;
	it's already a copy.  Free the signature probe unless it's cached.

1122 1123 1124
	* process.c (handle_child_signal): Fix crash; deleted pid (Bug#15106).

	* callproc.c (synch_process_fd): Remove.  All uses removed.
	(synch_process_tempfile): New var or macro.
	(CALLPROC_STDOUT, CALLPROC_STDERR, CALLPROC_PIPEREAD, CALLPROC_FDS):
	New constants.
	(record_kill_process): New arg, the temp name.  All callers changed.
	(delete_temp_file): Now just a simple wrapper around unlink.
	(call_process_kill): New arg, the call_process_fd array.
	Close them all.  Clear synch_process_pid.  Remove the temp file,
	or arrange for it to be removed.
	(call_process_cleanup) [MSDOS]: Arg no longer contains file name;
	that's been moved to synch_process_tempfile.  Caller changed.
	Do not remove the tempfile; that's now call_process_kill's
	responsibility.
	(call_process_cleanup) [!MSDOS]: Do not record unwind-protect for
	call_process_kill; the caller now does that.
	(call_process_cleanup): Do not close the process fd; that's now
	call_process_kill's responsibility.
	(Fcall_process): Implement via new function call_process, which
	has most of the old body of Fcall_process, but with a different API.
	(call_process): New function that does not open or close filefd if
	it is nonnegative.  Record which fds need to be closed, and let
	call_process_kill close (and remove the tempfile, on MSDOS) on error.
	Signal an error if invoked recursively (could be done via a hook).
	Simplify creation of the tempfile in the MSDOS case.
	Don't create the output file until after checking for the executable.
	Report any failure to open /dev/null.
	Don't open /dev/null for writing twice; once is enough.
	Don't create pipe if all output is being discarded or sent to file.
	Don't worry about setting up the coding system or reading from the
	pipe if all output is being discarded.
	Hoist fd_error local into top level, to lessen block nesting.
	Don't record deleted pid here; now done by Fcall_process_region.
	(Fcall_process) [MSDOS]: Report mktemp failure immediately,
	and note its success in synch_process_tempfile.
	Do not leak resources when child_setup fails.
	(Fcall_process) [!MSDOS && !WINDOWSNT]: Remove duplicate assignment
	to child_errno.  Remove unnecessary close of fd0; it's close-on-exec.
	(create_temp_file): Now returns open fd, with an additional
	Lisp_Object * argument to return the name.  All callers changed.
	Do not close the file; rewind it instead, and leave it open for
	the caller.  Do not lock the temp file.  Unwind-protect the file
	and the file-descriptor.
	(Fcall_process_region): If the input is /dev/null, unwind-protect it.
	If an asynchrounous process, record it here, not in call_process.
	(syms_of_callproc) [MSDOS]: Initialize synch_process_tempfile.
	* eval.c (set_unwind_protect): New function.
	* fileio.c (write_region): New function, generalized from the
	old Fwrite_region.  Do not lock temp files.
	(Fwrite_region): Use it.
	* lisp.h (set_unwind_protect, write_region): New decls.
	* process.c: Include <verify.h>.
	(make_process): Mark fds as initially closed.
	(deleted_pid_list): Now a list of pid-filename pairs.
	All uses changed.
	(close_process_fd): New function.
	(SUBPROCESS_STDIN, WRITE_TO_SUBPROCESS, READ_FROM_SUBPROCESS)
	(SUBPROCESS_STDOUT, READ_FROM_EXEC_MONITOR, EXEC_MONITOR_OUTPUT):
	New constants.  Verify that their number matches PROCESS_OPEN_FDS.
	(create_process, create_pty, Fmake_serial_process)
	(server_accept_connection): Record which fds need to be closed,
	and let deactivate_process close them.
	(Fmake_network_process): Do not discard the unwind-protect
	until it's safe to do so.
	(deactivate_process): Close the fds opened by create_process etc.
	(Fprocess_send_eof): Adjust to new way of recording open fds.
	Report an error if /dev/null can't be opened, instead of aborting.
	* process.h (PROCESS_OPEN_FDS): New constant.
	(struct Lisp_Process): New member open_fds.
	(record_kill_process, record_deleted_pid): Adjust signatures.
	(record_deleted_pid): Move decl here ...
	* syswait.h (record_deleted_pid): ... from here.

	* decompress.c: Fix bugs with large buffers and weird inputs.
	Tune a bit.  Reindent as per usual Emacs style.
	(BUFFER_SIZE): Remove.
	(Fdecompress_gzipped_region): Do not mishandle input buffers with
	more than UINT_MAX bytes.  Decompress into the gap instead of into
	an auto buffer, as this should avoid copying.  Return nil if
	'inflate' returns Z_NEED_DICT, as we have no dictionary.  Do not
	set immediate_quit; we shouldn't trust zlib code that much.
