Package: python3-keyrings.alt Version: 2.2-2 Severity: important Dear Maintainer,
When package 'keyrings' from python3-keyrings.alt is imported under python3.6, the module object has a __file__ attribute with a value None. This causes early failure of the Python 3.6 regression tests from libpython3.6-testsuite. The problem occurs starting at line 60 of /usr/lib/python3.6/test/libregrtest/setup.py, within a loop on the module objects listed in sys.modules.values(). The module object for 'keyrings' has a __file__ attribute, but it is None, so the call to os.path.abspath() fails with a TypeError on the non-string argument passed to it. Please note that when the 'keyrings' package from python3-keyrings.alt is imported into python3.7 (python3.7_3.7.0~b1-1_amd64), the 'keyrings' module object has no attribute __file__. Hence the tests from libpython3.7-testsuite run, even though libregrtest/setup.py is identical to the 3.6 version. Note also that when module keyrings.alt (as opposed to package keyrings) is imported in python3.6, the 'keyrings.alt' module object has a proper string-valued __file__ attribute. That doesn't help with the regression tests, however, since a 'keyrings' module object is listed in sys.modules.values(). It would appear that initialized module objects from import of package 'keyrings' should not have a __file__ attribute at all, which is consistent with python3.7's initialization. I happen to have python3-keyrings.alt installed because python3-jupyter-core recs python3-pip, which recs python3-wheel, which recs python3-keyrings.alt. I could probably remove the package without missing it. But my current workaround, and one you might consider, is to modify /usr/lib/python3.6/test/libregrtest/setup.py: 60c60 < if hasattr(module, '__file__'): --- > if hasattr(module, '__file__') and module.__file__ != None: -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.14.0-3-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages python3-keyrings.alt depends on: ii python3 3.6.4-1 ii python3-crypto 2.6.1-8 ii python3-six 1.11.0-2 python3-keyrings.alt recommends no packages.
