bpo-40173: Fix test.support.import_helper.import_fresh_module by serhiy-storchaka · Pull Request #28654 · python/cpython

serhiy-storchaka · Sep 30, 2021

Work correctly if an additional fresh module imports other
additional fresh module which imports a blocked module.
Raises ImportError if the specified module cannot be imported
while all additional fresh modules are successfully imported.
Support blocking packages.
Always restore the import state of fresh and blocked modules
and their submodules.

If you want to schedule another build, you need to add the ":hammer: test-with-buildbots" label again.

Failures of the multiprocessing tests on some buildbots look unrelated. There were same failures on them few days ago.

This seems like kind of a significant change to go through with no review, TBH. You even change a test in the decimal module!

I was in a hurry to fix refleak buildbots.

There were bugs in test_decimal and test_xml_etree. They depended on a side effect of import_fresh_module() which should not be.
