emacs, branch scratch/sigchld-fd

Don't crash if no asynchronous process has been created yet.

2021-01-16T18:46:44+00:00

* src/process.c (wait_reading_process_output): Allow
child_signal_read_fd < 0.

Fix deadlock when receiving SIGCHLD during 'pselect'.

2021-01-16T18:46:44+00:00

If we receive and handle a SIGCHLD signal for a process while waiting
for that process, 'pselect' might never return.  Instead, we have to
explicitly 'pselect' that the process status has changed.  We do this
by writing to a pipe in the SIGCHLD handler and having
'wait_reading_process_output' select on it.

* src/process.c (child_signal_init): New helper function to create a
pipe for SIGCHLD notifications.
(child_signal_read, child_signal_notify): New helper functions to
read from/write to the child signal pipe.
(create_process): Initialize the child signal pipe on first use.
(handle_child_signal): Notify waiters that a process status has
changed.
(wait_reading_process_output): Make sure that we also catch
SIGCHLD/process status changes.

* test/src/process-tests.el
(process-tests/fd-setsize-no-crash/make-process): Remove workaround,
which is no longer needed.

Fix Rmail summary for more than 99,999 messages

2021-01-16T18:18:32+00:00

* lisp/mail/rmailsum.el (rmail-summary-font-lock-keywords): Don't
assume there will be less than 100,000 messages in an mbox file.
(Bug#45912)

Fix two tests

2021-01-16T18:15:17+00:00

* test/lisp/progmodes/elisp-mode-tests.el (xref-elisp-test-run):
Make sure file names can be compared as strings, by running them
through 'file-truename'.  Reported by Vin Shelton
.
* test/lisp/emacs-lisp/bytecomp-tests.el ("warn-obsolete-hook.el")
("warn-obsolete-variable.el"): Use [^z-a] to match a newline as
well.  Reported by Vin Shelton .

test/infra/gitlab-ci.yml: run only for tags and some branches

2021-01-16T18:01:47+00:00

Improve support for Cham script

2021-01-16T14:54:01+00:00

* lisp/language/cham.el ("Cham"): Expand the entry.

* etc/HELLO: Add entry for Cham.

EMBA container build improvements for Emacs build testing.

2021-01-16T13:05:38+00:00

* test/infra/gitlab-ci.yml: Moved from .gitlab-ci.yml. Use the
EMBA container registry with a different login token storage file
for each commit. Split test stages into prep, build, fast tests,
normal tests, platform tests, and slow (everything) and use
templates where possible.

* .gitlab-ci.yml: Include test/infra/gitlab-ci.yml and move all
content there.

Fix last change

2021-01-16T13:02:48+00:00

* src/frame.c (Fset_mouse_position, Fset_mouse_pixel_position):
Don't compile the FRAME_MSDOS_P case on platforms other than
MSDOS, as that will never happen there.

Make mouse-related calls be more consistent on all frame types

2021-01-16T13:02:10+00:00

* src/frame.c (Fset_mouse_position, Fset_mouse_pixel_position): Call
Fselect_frame and appropriate mouse_moveto function on all non-GUI
frame types, independent of #ifdef's.
* src/term.c (init_tty): Initialize mouse_face_window for all
non-GUI frame types.
(term_mouse_moveto) [HAVE_GPM]: Make available even if
HAVE_WINDOW_SYSTEM is defined.
* src/xdisp.c (try_window_id): Call gui_clear_window_mouse_face
in all cases.

* lisp/frame.el Don't activate `blink-cursor-idle-timer` needlessly.

2021-01-16T04:18:08+00:00

(blink-cursor-mode): Use `blink-cursor-check` rather than
`blink-cursor--start-idle-timer` so we check for the presence of
a frame where the cursor can be blinked before activating the idle timer.
