[issue38172] Python 3.8 Segfult with Bandersnatch pytest Suite

[STINNER Victor]

STINNER Victor  added the comment:

I will do it differently. Nobody managed to reproduce the bug. The upstream CI 
looks to be fine. So I close the issue.

If someone sees a crash, please open a new issue with more context, like 
explain how to reproduce it ;-)

It seems now bandersnatch is tested with python 3.8.0 stable release and passes 
: https://travis-ci.org/pypa/bandersnatch/builds/599806554 . @cooperlees, can 
you please confirm and close the issue?

[Cooper Lees]

Cooper Lees  added the comment:

https://docs.travis-ci.com/user/languages/python/ make no mention of the 
difference between "3.8-dev" and "nightly". I'd expect it to be latest released 
3.8 alpha/beta and Trunk (or possibly trunk on 3.8 branch) respectively.

Have reached out via Twitter (unable to see a contact anywhere on their 
website) to see if we can get clarity:

I suggest to wait one or two weeks, and if the bug doesn't reoccur: simply 
close the issue.

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I am not sure about the difference between python 3.8-dev and nightly . The 
pipelines seem to have same configuration. The version on both pipelines is 
3.8.0b4+ and the nightly build passes : 
https://travis-ci.org/pypa/bandersnatch/jobs/588664064 . Maybe getting the 
exact commit hash for the python version might help here in trying to replicate 
the issue under the environment.

It can be a Python 3.8 or a bug in third party code. I suggest to attempt to 
reproduce the bug in gdb to collect more info about this crash.

STINNER Victor  added the comment:

The Travis CI job contains the Python traceback where the bug occurs.

It seems like the crash occurs at multidict/__init__.py:23 which imports 
multidict._multidict which is a C extension.

Happy to close, just was not 100% sure if the fix is merged into the 3.8 
branch. I mainly opened this bug to ensure that has been done.

If you mean that the crash no longer occurs with current 3.8.b4+ in the 
repository, then you should close as 'out-of-date.

Cooper Lees  added the comment:

Adding in Nightly Passed: https://travis-ci.org/pypa/bandersnatch/jobs/584977510

Current 3.8 beta still failing: 
https://travis-ci.org/pypa/bandersnatch/builds/584977503

So please just close if the bug was known etc. and I'll just live with the 
failing test until the next 3.8 comes out.
