* callproc.c (child_setup): When the child's exec fails, output
the program name, as that's more useful. Use O_NONBLOCK to avoid
deadlock.
* process.c (create_process_1): Remove; no longer needed.
(create_process): Remove timer hack; no longer needed, now that
the child avoids deadlock.
* lisp/image-dired.el (image-dired-track-original-file):
Use with-current-buffer.
(image-dired-track-thumbnail): Use with-current-buffer.
Avoid changing point of wrong window.
* configure.ac (PTY_TTY_NAME_SPRINTF): Use PTY_NAME_SIZE,
not sizeof pty_name, since pty_name is now a pointer to the array.
* src/process.c (PTY_NAME_SIZE): New constant.
(pty_name): Remove static variable; it's now auto.
(allocate_pty): Define even if !HAVE_PTYS; that's simpler.
Take pty_name as an arg rather than using a static variable.
All callers changed.
(create_process): Recover pty_flag from process, not from volatile local.
(create_pty): Stay inside array even when pty allocation fails.
(Fmake_serial_process): Omit unnecessary initializaiton of pty_flag.
* filelock.c (create_lock_file) [!O_CLOEXEC]: Use fcntl with FD_CLOEXEC.
(create_lock_file): Use write, not emacs_write.
* image.c (slurp_file, png_load_body):
* process.c (Fnetwork_interface_list, Fnetwork_interface_info)
(server_accept_connection):
Don't leak an fd on memory allocation failure.
* image.c (slurp_file): Add a cheap heuristic for growing files.
* xfaces.c (Fx_load_color_file): Block input around the fopen too,
as that's what the other routines do. Maybe input need not be
blocked at all, but it's better to be consistent.
Avoid undefined behavior when strlen is zero.
2013-07-19 Geoff Kuenning <geoff@cs.hmc.edu> (tiny change)
* gnus.texi (Customizing Articles): Document function predicates.
2013-07-19 Geoff Kuenning <geoff@cs.hmc.edu> (tiny change)
* gnus-art.el (gnus-treat-predicate): Allow functions as predicates (bug#13384).
2013-07-18 Lars Magne Ingebrigtsen <larsi@gnus.org>
* gnus-start.el (gnus-clean-old-newsrc): Remove the newsrc cleanups
that were only relevant in a development version a long time ago.
src/keyboard.c (kbd_buffer_get_event): Use Display_Info instead of
unportable 'struct x_display_info'.
(DISPLAY_LIST_INFO): Delete macro: not needed, since Display_Info
is a portable type.
(procfs_ttyname): Don't use uninitialized storage if emacs_fopen
or fscanf fails.
(system_process_attributes): Prefer plain char to unsigned char
when either will do. Clean up properly if interrupted or if
memory allocations fail. Don't assume sscanf succeeds. Remove
no-longer-needed workaround to stop GCC from whining. Read
command-line once, instead of multiple times. Check read status a
bit more carefully.
The code assumed that int is treated like ptrdiff_t in a vararg
function, which is not a portable assumption. There was a similar
-- though these days less likely -- porting problem with various
assumptions that pointers of different types all smell the same as
far as vararg functions is conserved. To make this problem less
likely in the future, redo the API to use varargs functions.
* alloc.c (make_save_value): Remove this vararg function.
All uses changed to ...
(make_save_int_int_int, make_save_obj_obj_obj_obj)
(make_save_ptr_int, make_save_funcptr_ptr_obj, make_save_memory):
New functions.
(make_save_ptr): Rename from make_save_pointer, for consistency with
the above. Define only on platforms that need it. All uses changed.
(get_boot_time_1): Rework to avoid using emacs_open.
This doesn't actually fix a leak, but is better anyway.
(read_lock_data): Use read, not emacs_read.
`file-notify-support'. Do not autoload. Adapt all uses.
(file-notify-supported-p): New defun.
* autorevert.el (auto-revert-use-notify): Use
`file-notify-supported-p' instead of `file-notify-support'. Adapt
docstring.
(auto-revert-notify-add-watch): Use `file-notify-supported-p'.
* net/tramp.el (tramp-file-name-for-operation):
Add `file-notify-supported-p'.
* net/tramp-sh.el (tramp-sh-handle-file-notify-supported-p):
New defun.
(tramp-sh-file-name-handler-alist): Add it as handler for
`file-notify-supported-p '.
* net/tramp-adb.el (tramp-adb-file-name-handler-alist):
* net/tramp-gvfs.el (tramp-gvfs-file-name-handler-alist):
* net/tramp-smb.el (tramp-smb-file-name-handler-alist):
Add `ignore' as handler for `file-notify-*' functions.
Include <errno.h>.
(load_charset_map_from_file): Don't leak file descriptor on error.
Use plain record_xmalloc since the allocation is larger than
MAX_ALLOCA; that's simpler here. Simplify test for exhaustion
of entries.
* eval.c (record_unwind_protect_nothing):
* fileio.c (fclose_unwind):
New functions.
* lread.c (load_unwind): Remove. All uses replaced by fclose_unwind.
The replacement doesn't block input, but that no longer seems
necessary.
(Fload): Close some races that leaked fds or streams when 'load'
was interrupted.
(Fload, openp): Report error number of last nontrivial failure to open.
ENOENT counts as trivial.
* eval.c (do_nothing, clear_unwind_protect, set_unwind_protect_ptr):
New functions.
* fileio.c (close_file_unwind): No need to test whether FD is nonnegative,
now that the function is always called with a nonnegative arg.
* lisp.h (set_unwind_protect_ptr, set_unwind_protect_int): Remove.
All uses replaced with ...
(clear_unwind_protect, set_unwind_protect_ptr): New decls.
* callproc.c (Fcall_process_region): Pass nil, not "/dev/null",
to Fcall_process when the input is empty. This simplifies the
code a bit. It makes no difference on POSIXish platforms but
apparently it fixes a bug on w32.
