*	gh-96819: multiprocessing.resource_tracker: check if length of pipe write <= ↵	Miss Islington (bot)	2022-10-03	1	-2/+2

*	bpo-40692: Run more test_concurrent_futures tests (GH-20239)	Asheesh Laroia	2021-02-08	1	-1/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	In the case of multiprocessing.synchronize() being missing, the test_concurrent_futures test suite now skips only the tests that require multiprocessing.synchronize(). Validate that multiprocessing.synchronize exists as part of _check_system_limits(), allowing ProcessPoolExecutor to raise NotImplementedError during __init__, rather than crashing with ImportError during __init__ when creating a lock imported from multiprocessing.synchronize. Use _check_system_limits() to disable tests of ProcessPoolExecutor on systems without multiprocessing.synchronize. Running the test suite without multiprocessing.synchronize reveals that Lib/compileall.py crashes when it uses a ProcessPoolExecutor. Therefore, change Lib/compileall.py to call _check_system_limits() before creating the ProcessPoolExecutor. Note that both Lib/compileall.py and Lib/test/test_compileall.py were attempting to sanity-check ProcessPoolExecutor by expecting ImportError. In multiprocessing.resource_tracker, sem_unlink() is also absent on platforms where POSIX semaphores aren't available. Avoid using sem_unlink() if it, too, does not exist.

*	bpo-38546: multiprocessing tests stop the resource tracker (GH-17641)	Victor Stinner	2019-12-17	1	-0/+13
\| \| \| \| \| \| \| \| \| \|	Multiprocessing and concurrent.futures tests now stop the resource tracker process when tests complete. Add ResourceTracker._stop() method to multiprocessing.resource_tracker. Add _cleanup_tests() helper function to multiprocessing.util: share code between multiprocessing and concurrent.futures tests.

*	bpo-36867: Make semaphore_tracker track other system resources (GH-13222)	Pierre Glaser	2019-05-10	1	-0/+213
	The multiprocessing.resource_tracker replaces the multiprocessing.semaphore_tracker module. Other than semaphores, resource_tracker also tracks shared_memory segments. Patch by Pierre Glaser.
