New submission from Steve Dower <steve.do...@python.org>:
The Windows CI machines on Azure Pipelines run additional tests to check an "installed" layout and with the UWP entry point that's used for the Windows Store package. These tests have been failing intermittently (though regularly) with a stack overflow crash in the PyPickler tests. Example: https://dev.azure.com/Python/cpython/_build/results?buildId=62055&view=results test_attribute_name_interning (test.test_pickle.PyPicklerTests) ... ok File "D:\a\1\b\layout-appx-amd64\lib\test\pickletester.py", line 3085 in __getattr__ File "D:\a\1\b\layout-appx-amd64\lib\test\pickletester.py", line 3085 in __getattr__ File "D:\a\1\b\layout-appx-amd64\lib\test\pickletester.py", line 3085 in __getattr__ File "D:\a\1\b\layout-appx-amd64\lib\test\pickletester.py", line 3085 in __getattr__ ... I assume this is due to having more code on the start at the start, and so the recursion limit isn't low enough. But it might also be worth checking this particular case to see whether there is unnecessary data being kept on the stack (e.g. in local C variables). The crash occurs in both 3.8 and master, but not 3.7. ---------- components: Windows messages: 367803 nosy: paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal status: open title: test_attribute_name_interning crashes on APPX test versions: Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40458> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
