New submission from Max: There's a known issue with `shutil.rmtree` on Windows, in that it fails intermittently.
The issue is well known (https://mail.python.org/pipermail/python-dev/2013-September/128353.html), and the agreement is that it cannot be cleanly solved inside `shutil` and should instead be solved by the calling app. Specifically, python devs themselves faced it in their test suite and solved it by retrying delete. However, what to do about `tempfile.TemporaryDirectory`? Is it considered the calling app, and therefore should retry delete when it calls `shutil.rmtree` in its `cleanup` method? I don't think `tempfile` is protected by the same argument that `shutil.rmtree` is protected, in that it's too messy to solve it in the standard library. My rationale is that while it's very easy for the end user to retry `shutil.rmtree`, it's far more difficult to fix the problem with `tempfile.TempDirectory` not deleting itself - how would the end user retry the `cleanup` method (which is called from `weakref.finalizer`)? So perhaps the retry loop should be added to `cleanup`. ---------- components: Library (Lib) messages: 291130 nosy: max priority: normal severity: normal status: open title: tempfile.TemporaryDirectory fails to delete itself type: behavior versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29982> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
