Fix process-tests on MS-Windows

2020-12-31T14:50:19+00:00

* test/src/process-tests.el (process-tests--fd-setsize-test): On
MS-Windows start the pipe processes in the "stopped" condition.

* test/src/process-tests.el: Let timeouts fail the tests. Fix some docstrings

2020-12-31T14:00:41+00:00

Unbreak process tests if 'errno' is not installed.

2020-12-31T12:17:11+00:00

* test/src/process-tests.el (process-tests--EMFILE-message): Don't
signal an error if the 'errno' binary is unavailable.

Manually limit file descriptors that we select on to FD_SETSIZE.

2020-12-30T23:18:02+00:00

This works even if another thread or process resets the resource limit
for open file descriptors, e.g., using 'prlimit' on GNU/Linux.

* src/process.c (create_process, create_pty, Fmake_pipe_process)
(Fmake_serial_process, connect_network_socket)
(server_accept_connection): Limit file descriptors to FD_SETSIZE.
* test/src/process-tests.el (process-tests--with-raised-rlimit): New
helper macro.
(process-tests--fd-setsize-test): Rename from
'process-tests--with-many-pipes'.  Increase resource limit during test
if possible.
(process-tests/fd-setsize-no-crash/make-process)
(process-tests/fd-setsize-no-crash/make-pipe-process)
(process-tests/fd-setsize-no-crash/make-network-process)
(process-tests--new-pty): Rename callers.

Fix a potential unit test breakage on GNU/Linux.

2020-12-30T23:06:04+00:00

* test/src/process-tests.el
(process-tests/fd-setsize-no-crash/make-process): Allow special exit
codes that can happen if terminal setup fails in the child process.

Fix an incorrect Edebug specification.

2020-12-30T22:13:19+00:00

* test/src/process-tests.el (process-tests--with-many-pipes): Fix
incorrect Edebug specification.

Extend and overhaul FD_SETSIZE overflow tests.

2020-12-30T22:04:31+00:00

Instead of trying to generate the right number of processes,
pre-create lots of unused pipe processes until creation fails.  Extend
the tests to the 'pty' connection type and other kinds of process
objects.

* test/src/process-tests.el (process-tests--ignore-EMFILE)
(process-tests--with-buffers, process-tests--with-processes)
(process-tests--with-many-pipes, process-tests--with-temp-file)
(process-tests--with-temp-directory): New helper macros.
(process-tests/fd-setsize-no-crash/make-process): Renamed from
'process-tests/fd-setsize-no-crash'.  Fail on timeout.  Also test the
'pty' connection type.  Pre-create lots of pipe processes so we reach
the FD_SETSIZE limit faster.  Ignore EMFILE more precisely, if
possible.
(process-tests/fd-setsize-no-crash/make-pipe-process)
(process-tests/fd-setsize-no-crash/make-network-process)
(process-tests/fd-setsize-no-crash/make-serial-process): New tests
that test FD_SETSIZE limits for other kinds of processes.
(process-tests--EMFILE-message): New helper function and cache
variable.
(process-tests--new-pty): New helper function.

; * test/src/process-tests.el: Fix comment style.

2020-12-30T21:36:42+00:00

; Fix my previous commit

2020-12-30T07:36:04+00:00

* test/src/chartab-tests.el (chartab-test-char-table-extra-slot): Fix
test.

Add some char-table tests

2020-12-30T07:32:36+00:00

* test/src/chartab-tests.el (chartab-test-char-table-p)
(chartab-test-char-table-subtype)
(chartab-test-char-table-parent)
(chartab-test-char-table-extra-slot): New tests.
