2025-12-03Closed pool when parallel test runner encounters unpicklable exceptions.Jacob Walls
2025-10-29Fixed #36678 -- Limited retries in ParallelTestRunner.Jacob Walls
Thanks Natalia Bidart for the review.
2025-10-28Fixed #36596 -- Made parallel test runner respect django_test_skips and ↵Mariusz Felisiak
django_test_expected_failures.
2025-10-21Fixed #36677 -- Fixed scheduling of system checks in ParallelTestSuite workers.Jacob Walls
Running system checks in workers must happen after database aliases are set up. Regression in 606fc352799e372928fa2c978ab99f0fb6d6017c.
2025-09-26Fixed #36491 -- Fixed crash in ParallelTestRunner with --buffer.Shubham Singh
Thanks Javier Buzzi and Adam Johnson for reviews. Co-authored-by: Simon Charette <charette.s@gmail.com>
2025-09-16Fixed #36083 -- Ran system checks in ParallelTestSuite workers.Adam Zapletal
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.

Thanks to Jacob Walls for the report and previous iterations of this fix, to Simon Charette for the logging formatter idea, and to Tim Graham for testing and ensuring that 3rd party backends remain compatible. This partially reverts d8f093908c504ae0dbc39d3f5231f7d7920dde37. Refs #36112, #35448. Co-authored-by: Jacob Walls <jacobtylerwalls@gmail.com>

successes.
2021-10-12Fixed #28401 -- Allowed hashlib.md5() calls to work with FIPS kernels.Ade Lee
md5 is not an approved algorithm in FIPS mode, and trying to instantiate a hashlib.md5() will fail when the system is running in FIPS mode. md5 is allowed when in a non-security context. There is a plan to add a keyword parameter (usedforsecurity) to hashlib.md5() to annotate whether or not the instance is being used in a security context. In the case where it is not, the instantiation of md5 will be allowed. See https://bugs.python.org/issue9216 for more details. Some downstream python versions already support this parameter. To support these versions, a new encapsulation of md5() has been added. This encapsulation will pass through the usedforsecurity parameter in the case where the parameter is supported, and strip it if it is not.

2021-08-05Fixed #32988 -- Prevented creation of more test databases than TestCases.Mariusz Felisiak

DiscoverRunner.build_suite()/run_tests().
2021-07-12Fixed #32914 -- Prevented test --shuffle from skipping test methods.Chris Jerdonek
"test --shuffle" skipped test methods when test classes were mixed. This changes runner.py's reorder_tests() to group by TestCase class. Regression in 90ba716bf060ee7fef79dc230b0b20644839069f.

For example, with this change, the following now works from the tests directory: $ ./runtests.py view_tests/tests/
2021-06-10Refs #27734 -- Prevented creation of more parallel workers than TestCases.Ceesjan Luiten
The parallel test runner uses multiple workers to distribute the workload. These workers are assigned a worker ID using a globally incremented variable, which determines what test database to connect to. When the worker ID surpasses the test database IDs Django will crash. This reduce likelihood of crashing parallel tests because ParallelTestSuite will no longer create more workers than TestCases. It won't eliminate the problem completely though because there are other circumstances in which new workers can be created which can then be assigned an "illegal" worker ID.
2021-06-03Fixed #32808 -- Prevented DiscoverRunner.build_suite() from mutating test ↵Mariusz Felisiak
loader patterns. Thanks Chris Jerdonek for the report and reviews.
