[6.0.x] Applied Black's 2026 stable style.

2026-02-24T23:36:09Z

https://github.com/psf/black/releases/tag/26.1.0 Backport of 6cff02078799b7c683a0d39630d49ab4fe532e7c from main.

[6.0.x] Made RemoteTestResultTest.test_pickle_errors_detection() compatible with tblib 3.2+.

2025-10-22T02:11:08Z

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. Backport of 548209e620b3ca34396a360453f07c8dbb8aa6c7 from main.

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.
