| | | | | | On Linux, skip tests using multiprocessing if the current user cannot create a file in /dev/shm/ directory. Add the skip_if_broken_multiprocessing_synchronize() function to the test.support module.

* bpo-39360: Ensure all workers exit when finalizing a multiprocessing Pool ↵Batuhan Taşkaya2020-03-151-0/+18
| | | | | | | | | (GH-19009) When the pull is not used via the context manager or terminate() is called, there is a system in multiprocessing.util that handles finalization of all pools via an atexit handler (the Finalize) class. This class registers the _terminate_pool handler in the registry of finalizers of the module, and that registry is called on interpreter exit via _exit_function. The problem is that the "happy" path with the context manager or manual call to finalize() does some extra steps that _terminate_pool does not. The step that is not executed when the atexit() handler calls _terminate_pool is pinging the _change_notifier queue to unblock the maintenance threads. This commit moves the notification to the _terminate_pool function so is called from both code paths. Co-authored-by: Pablo Galindo <Pablogsal@gmail.com>

* bpo-38546: multiprocessing tests stop the resource tracker (GH-17641)Victor Stinner2019-12-171-10/+1
| | | | | | | | | | 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-38614: Use support timeout constants (GH-17572)HEADmasterVictor Stinner2019-12-111-4/+3
|
* bpo-38614: Use test.support.SHORT_TIMEOUT constant (GH-17566)Victor Stinner2019-12-111-1/+1
| | | | | | | | | | | | | | | Replace hardcoded timeout constants in tests with SHORT_TIMEOUT of test.support, so it's easier to ajdust this timeout for all tests at once. SHORT_TIMEOUT is 30 seconds by default, but it can be longer depending on --timeout command line option. The change makes almost all timeouts longer, except test_reap_children() of test_support which is made 2x shorter: SHORT_TIMEOUT should be enough. If this test starts to fail, LONG_TIMEOUT should be used instead. Uniformize also "from test import support" import in some test files.
* bpo-38614: Use test.support.LONG_TIMEOUT constant (GH-17562)Victor Stinner2019-12-101-2/+2
| | | | | | | | Replace hardcoded timeout constants in tests with LONG_TIMEOUT of test.support, so it's easier to ajdust this timeout for all tests at once. LONG_TIMEOUT is 5 minutes by default, but it can be longer depending on --timeout command line option.
* bpo-38707: Fix for multiprocessing.Process MainThread.native_id (GH-17088)Jake Tesler2019-11-191-0/+22
| | | | | | | | | | | | | | | | | | | This PR implements a fix for `multiprocessing.Process` objects; the error occurs when Processes are created using either `fork` or `forkserver` as the `start_method`. In these instances, the `MainThread` of the newly created `Process` object retains all attributes from its parent's `MainThread` object, including the `native_id` attribute. The resulting behavior is such that the new process' `MainThread` captures an incorrect/outdated `native_id` (the parent's instead of its own). This change forces the Process object to update its `native_id` attribute during the bootstrap process. cc @vstinner https://bugs.python.org/issue38707 Automerge-Triggered-By: @pitrou
* bpo-38614: Add timeout constants to test.support (GH-16964)Victor Stinner2019-10-301-12/+6
| | | | | | | | Add timeout constants to test.support: * LOOPBACK_TIMEOUT * INTERNET_TIMEOUT * SHORT_TIMEOUT * LONG_TIMEOUT
* bpo-37123: multiprocessing test_mymanager() accepts SIGTERM (GH-16349)Victor Stinner2019-09-241-5/+6
| | | | | | | | Multiprocessing test test_mymanager() now also expects -SIGTERM, not only exitcode 0. bpo-30356: BaseManager._finalize_manager() sends SIGTERM to the manager process if it takes longer than 1 second to stop, which happens on slow buildbots.
* bpo-38212: Increase MP test_queue_feeder_donot_stop_onexc() timeout (GH-16348)Victor Stinner2019-09-241-2/+1
| | | | Multiprocessing tests: increase test_queue_feeder_donot_stop_onexc() timeout from 1 to 60 seconds.

* bpo-37558: Shared memory tests are failing due to double slashes (GH-14703)Jakub Kulík2019-07-111-1/+1
| | | | | | With the addition of shared memory into Python 3.8, we now have three tests failing on Solaris, namely `test_multiprocessing_fork`, `test_multiprocessing_forkserver` and `test_multiprocessing_spawn`. The reason seems to be incorrect name handling which results in two slashes being prepended. https://bugs.python.org/issue37558
* bpo-37421: multiprocessing tests now stop ForkServer (GH-14601)Victor Stinner2019-07-051-0/+6
| | | | | multiprocessing tests now stop the ForkServer instance if it's running: close the "alive" file descriptor to ask the server to stop and then remove its UNIX address.
* bpo-37421: multiprocessing tests call _run_finalizers() (GH-14527)Victor Stinner2019-07-021-0/+3
| | | | | multiprocessing tests now call explicitly _run_finalizers() to remove immediately temporary directories created by multiprocessing.util.get_temp_dir().

Provide shm_open() and shm_unlink() functions. Move other functionality into the shared_memory.py module. * Added to doc around size parameter of SharedMemory. * Changed PosixSharedMemory.size to use os.fstat. * Change SharedMemory.buf to a read-only property as well as NamedSharedMemory.size. * Marked as provisional per PEP411 in docstring. * Changed SharedMemoryTracker to be private. * Removed registered Proxy Objects from SharedMemoryManager. * Removed shareable_wrap(). * Removed shareable_wrap() and dangling references to it. * For consistency added __reduce__ to key classes. * Fix for potential race condition on Windows for O_CREX. * Remove unused imports. * Update access to kernel32 on Windows per feedback from eryksun. * Moved kernel32 calls to _winapi. * Removed ShareableList.copy as redundant. * Changes to _winapi use from eryksun feedback. * Adopt simpler SharedMemory API, collapsing PosixSharedMemory and WindowsNamedSharedMemory into one. * Fix missing docstring on class, add test for ignoring size when attaching. * Moved SharedMemoryManager to managers module, tweak to fragile test. * Tweak to exception in OpenFileMapping suggested by eryksun. * Mark a few dangling bits as private as suggested by Giampaolo.

* bpo-35378: Fix multiprocessing.Pool references (GH-11627)Pablo Galindo2019-02-111-1/+0
| | | | | | | | | Changes in this commit: 1. Use a _strong_ reference between the Pool and associated iterators 2. Rework PR #8450 to eliminate a cycle in the Pool. There is no test in this commit because any test that automatically tests this behaviour needs to eliminate the pool before joining the pool to check that the pool object is garbaged collected/does not hang. But doing this will potentially leak threads and processes (see https://bugs.python.org/issue35413).
