#339 / v4.8.0 broke stevedore which broke bandit, openstackclient, flake8 and others #348

mr-c · 2021-08-29T10:08:52Z

Hello, #339 in v4.8.0 broke stevedore which broke bandit for at least myself (but probably others)

https://github.com/common-workflow-language/cwltool/pull/1482/checks?check_run_id=3454232416#step:9:50
PyCQA/bandit#730

Reverting to importlib_metadata version 4.7.1 resolves the problem for me

Seems to break openstack cli and rally testing as well. Opening https://storyboard.openstack.org/#!/story/2009151

WilliamDEdwards · 2021-08-29T12:44:43Z

Same here with flake8 (uses stevedore). I created a stevedore bug here: https://bugs.launchpad.net/python-stevedore/+bug/1941991

jaraco · 2021-08-29T13:29:57Z

Sorry for the inconvenience. I've yanked 4.8.0 while working out a remedy.

The recent release of importlib-metadata has broken an interface that stevedore uses when looking for entrypoints (see python/importlib_metadata#348 ). Several of our test/ci dependecies use stevedore for their plugin interfaces including stestr which is causing CI failures. To unblock CI this commit pins the importlib metadata version in our constraints file while the upstream issue is resolved.

jaraco · 2021-08-29T13:36:58Z

I'd like devise a way to capture these requirements. I can see from the failure that stevedore is expecting __getitem__(slice) to return a tuple, something that namedtuple (or other tuple) would do implicitly.

jaraco · 2021-08-29T13:38:28Z

@mtreinish: You may wish to refrain from pinning too many projects as I've yanked the offending version and expect to release the next version without the broken behavior.

mr-c · 2021-08-29T13:46:13Z

Thanks for the quick yank! I know this isn't nice news to receive.

jaraco · 2021-08-29T14:07:47Z

In #349, I've drafted a fix but marking the access by item as deprecated. I can add other missing but expected tuple behaviors there as well if needed. I welcome feedback.

jaraco · 2021-08-29T15:14:27Z

v4.8.1 is releasing now. I believe this addresses the issue. It's possible there are other usages out there dependent on tuple behaviors. If so, please raise an issue, mention me, and I'll address those promptly.

I'm not confident of the report above for a couple of reasons.

First, the report doesn't include the actual error message. It includes a screenshot with only a FileNotFoundError.

Second, the issue reported above was addressed in 4.8.1, but the changes made in the 5.0 release were made against 5fb7029, released in 4.4.0.

Most importantly, importlib_metadata 5 still retains the tuple item access support (deprecated) added in v4.8.1.

Probably the user is reporting the issue reported in #409.

jacwalte · 2022-10-03T23:46:00Z

@jaraco I updated my comment with the full content of the error provided by the ADO (Azure Dev Ops) task.

commands that ran the task.

source $CONDA/bin/activate
python -m pip install safety==2.1.1 bandit==1.7.4
safety check
bandit --recursive .

We were not specifying the version of importlib-metadata or that it be installed here. I updated the python -m pip command to include importlib-metadata==4.13.0 and now everything is passing as expected.

new command

source $CONDA/bin/activate
python -m pip install importlib-metadata==4.13.0 safety==2.1.1 bandit==1.7.4
safety check
bandit --recursive .

Please let me know if I can provide more details.

Thanks!
Jack Walters

jaraco · 2022-10-03T23:56:44Z

Thanks. Yes, I can confirm with that traceback that it's a different issue, the one reported in #409, and that this issue could still potentially affect stevedore too, if the deprecation isn't addressed.

jaraco · 2022-10-04T15:51:46Z

@devturner Your issue is in #409.

jaraco · 2022-10-04T15:54:43Z

In 1343876, I've added a note to block the removal of the DeprecatedTuple, which deprecates the item access of an EntryPoint, until 2023-05-01 based on feedback in #409.
