Closed pool when parallel test runner encounters unpicklable exceptions.

2025-12-03T21:04:22Z

Made RemoteTestResultTest.test_pickle_errors_detection() compatible with tblib 3.2+.

2025-10-22T02:10:31Z

tblib 3.2+ makes exception subclasses with __init__() and the default __reduce__() picklable. This broke the test for RemoteTestResult._confirm_picklable(), which expects a specific exception to fail unpickling. https://github.com/ionelmc/python-tblib/blob/master/CHANGELOG.rst#320-2025-10-21 This fix defines ExceptionThatFailsUnpickling.__reduce__() in a way that pickle.dumps(obj) succeeds, but pickle.loads(pickle.dumps(obj)) raises TypeError. Refs #27301. This preserves the intent of the regression test from 52188a5ca6bafea0a66f17baacb315d61c7b99cd without skipping it.

Refs #36491 -- Skipped ParallelTestSuiteTest.test_buffer_mode_reports_setupclass_failure() without tblib.

Fixed #36083 -- Ran system checks in ParallelTestSuite workers.

2025-09-17T01:57:22Z

Workers created by ParallelTestSuite were not running system checks in the spawn multiprocessing mode. In general this is fine, but system checks can have side effects expected by tests. This patch runs system checks inside of _init_worker, which is only called by ParallelTestSuite.

Fixed #36005 -- Dropped support for Python 3.10 and 3.11.

2025-01-20T13:07:28Z

Removed redundant RemoteTestResultTest._test_error_exc_info() test hook.

Refs #35849 -- Skipped ParallelTestSuiteTest.test_handle_add_error_before_first_test() without tblib.
