* | * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.Paul Eggert2012-12-121-0/+9
| | | | | | | | | | | | | | | | fstat shouldn't fail, and if it does fail copy-file should not proceed. Remove unnecessary S_ISLNK test, as (contra the comments) this function can't copy symlinks. Improve quality of error message when attempting to copy files that are neither regular files nor directories.
* | * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.Dmitry Antipov2012-12-121-0/+8
| | | | | | | | | | | | | | * gtkutil.c (xg_set_toolkit_scroll_bar_thumb): * window.c (Frecenter): * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs): * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.

(append_space_for_newline): If the glyph row is R2L, reset the iterator's end_of_box_run_p flag before prepending the space glyph. (extend_face_to_end_of_line): If the glyph row is R2L, reset the iterator's start_of_box_run_p flag before prepending the stretch. (append_glyph, produce_image_glyph, append_composite_glyph) (append_stretch_glyph, append_glyphless_glyph): Reverse the left_box_line_p and right_box_line_p flags of the glyph for R2L glyph rows.

(Fset_time_zone_rule): Do not save TZ and environ; no longer needed here. (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]: Move to inside set_time_zone_rule; they don't need file scope any more.

Do not worry about SIGCLD any more. * src/syssignal.h (EMACS_KILLPG): Remove. All uses replaced by 'kill' with a negative pid. (SIGCHLD): Remove definition, as we now assume SIGCHLD. * src/w32proc.c (sys_kill): Support negative pids compatibly with POSIX. Fixes: debbugs:13026
| * | * sysdep.c (get_child_status): Abort on internal error (Bug#13086).Paul Eggert2012-12-071-0/+6
| | | | | | | | | | | | | | | This will cause a production Emacs to dump core instead of infinite-looping.
| * | * frame.c (make_frame): Do not set window's buffer to t.Dmitry Antipov2012-12-071-0/+8
| | | | | | | | | | | | | | | | | | | | | * window.c (Fsplit_window_internal): Likewise. Previously it was used to indicate that the window is being set up. Now we use set_window_buffer for all new windows, so the condition in ... (Fset_window_buffer): ... is always true and can be removed.
| * | Convenient macro to check whether the buffer is hidden.Dmitry Antipov2012-12-071-0/+8
| | | | | | | | | | | | | | | | | | | | | * buffer.h (BUFFER_HIDDEN_P): New macro. * frame.c (make_frame): Use it. Adjust comment. * buffer.c (candidate_buffer): New function. (Fother_buffer, other_buffer_safely): Use it.
| * | Avoid busy-waiting for child processes on Windows. (Bug#13086)Eli Zaretskii2012-12-061-0/+6
| | | | | | | | | | | | | | | | | | src/w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG if the child process is still running. Instead, exit the wait loop and return zero.
| * | * frame.h (x_char_width, x_char_height): Remove prototypes.Dmitry Antipov2012-12-061-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * w32term.h (x_char_width, x_char_height): Likewise. * xfns.c (x_char_width, x_char_height): Remove. * w32fns.c (x_char_width, x_char_height): Likewise. * nsfns.c (x_char_width, x_char_height): Likewise. * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for all window frames. (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT. * keyboard.c (command_loop_1): Remove prototype. (command_loop_2, top_level_1): Add static to match prototype.
| * | Fix a recently-introduced delete-process race condition.Paul Eggert2012-12-051-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | * callproc.c, process.h (record_kill_process): New function, containing part of the old call_process_kill. (call_process_kill): Use it. This does not change call_process_kill's behavior. * process.c (Fdelete_process): Use record_kill_process to fix a race condition that could cause Emacs to lose track of a child.
| * | Avoid code duplication between prev_frame and next_frame.Dmitry Antipov2012-12-061-0/+6
| | | | | | | | | | | | | | | * frame.c (candidate_frame): New function. Add comment. (prev_frame, next_frame): Use it. Adjust comment.

| | | | | | | | | | | | | | | src/callproc.c (Fcall_process_region): Encode expanded temp file pattern before passing it to mkstemp or mktemp.
| | * Fix one part of bug #13079 with temporary files in call-process-region.Eli Zaretskii2012-12-051-0/+6
| | | | | | | | | | | | | | | | | | src/callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp fails, signal an error instead of continuing with an empty string.
| | * Fix another instance of bug #12933 with non-ASCII file names on Windows.Eli Zaretskii2012-12-041-0/+7
| | | | | | | | | | | | | | | | | | src/fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]: Encode the file name before passing it to dostounix_filename, in case it will downcase it (under w32-downcase-file-names).

Convert term_initted, delete_in_insert_mode, costs_set, insert_mode, standout_mode, cursor_hidden and flow_control members to a bitfields.
| * | Don't let call-process be a zombie factory.Paul Eggert2012-12-031-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixing this bug required some cleanup of the signal-handling code. As a side effect, this change also fixes a longstanding rare race condition whereby Emacs could mistakenly kill unrelated processes, and it fixes a bug where a second C-g does not kill a recalcitrant synchronous process in GNU/Linux and similar platforms. The patch should also fix the last vestiges of Bug#9488, a bug which has mostly been fixed on the trunk by other changes. * callproc.c, process.h (synch_process_alive, synch_process_death) (synch_process_termsig, sync_process_retcode): Remove. All uses removed, to simplify analysis and so that less consing is done inside critical sections. * callproc.c (call_process_exited): Remove. All uses replaced with !synch_process_pid. * callproc.c (synch_process_pid, synch_process_fd): New static vars. These take the role of what used to be in unwind-protect arg. All uses changed. (block_child_signal, unblock_child_signal): New functions, to avoid races that could kill innocent-victim processes. (call_process_kill, call_process_cleanup, Fcall_process): Use them. (call_process_kill): Record killed processes as deleted, so that zombies do not clutter up the system. Do this inside a critical section, to avoid a race that would allow the clutter. (call_process_cleanup): Fix code so that the second C-g works again on common platforms such as GNU/Linux. (Fcall_process): Create the child process in a critical section, to fix a race condition. If creating an asynchronous process, record it as deleted so that zombies do not clutter up the system. Do unwind-protect for WINDOWSNT too, as that's simpler in the light of these changes. Omit unnecessary call to emacs_close before failure, as the unwind-protect code does that. * callproc.c (call_process_cleanup): * w32proc.c (waitpid): Simplify now that synch_process_alive is gone. * process.c (record_deleted_pid): New function, containing code refactored out of Fdelete_process. (Fdelete_process): Use it. (process_status_retrieved): Remove. All callers changed to use child_status_change. (record_child_status_change): Remove, folding its contents into ... (handle_child_signal): ... this signal handler. Now, this function is purely a handler for SIGCHLD, and is not called after a synchronous waitpid returns; the synchronous code is moved to wait_for_termination. There is no need to worry about reaping more than one child now. * sysdep.c (get_child_status, child_status_changed): New functions. (wait_for_termination): Now takes int * status and bool interruptible arguments, too. Do not record child status change; that's now the caller's responsibility. All callers changed. Reimplement in terms of get_child_status. (wait_for_termination_1, interruptible_wait_for_termination): Remove. All callers changed to use wait_for_termination. * syswait.h: Include <stdbool.h>, for bool. (record_child_status_change, interruptible_wait_for_termination): Remove decls. (record_deleted_pid, child_status_changed): New decls. (wait_for_termination): Adjust to API changes noted above. Fixes: debbugs:12980
| * | * bytecode.c, lisp.h (Qbytecode): Remove.Paul Eggert2012-12-031-0/+5
