[python-committers] Re: Python Language Summit at PyCon 2020

[Mariatta]

Just to remind everyone that signup to the language summit is still open
for another 11 days.

So far folks have proposed topic like: f-strings, CPython’s documentation,
PEG parser, property-based testing, and more!

We’ve received a number inquiries about the language summit, so here are
some Q:

1. Do I need to sign up if I’m a Python core developer?

Yes please! Attendance is limited to 50 people. Please register to reserve
your seat in the room.

2. Can I sign up if I’m not a Python core developer?

Yes you can. Last year we had 15 participants (out of 50) who were not
Python core devs. Among them were maintainers and representatives from
BeeWare, CircuitPython, PSF board member, PyCharm, etc.

[python-committers] Re: Cannot release 3.9.0a4

[Jason R. Coombs]

The Fedora failures in shutil and zipfile are "no space left on device". Seems 
like an environment/infrastructure issue.

The failures in the Windows build also seem to implicate importlib (though with 
an obscure error). I looked into those and they don't appear to relate to 
anything I've worked on, but someone please let me know if find otherwise.

Subject: [python-committers] Cannot release 3.9.0a4

Currently Buildbots are reporting that master is not in a releasable state:
https://buildbot.python.org/all/#/release_status

Namely, it does not build on Windows 7:
- https://buildbot.python.org/all/#/builders/150/builds/338
- https://buildbot.python.org/all/#/builders/81/builds/390

and suffers from test failures on:
- macOS (importlib) - https://buildbot.python.org/all/#/builders/275/builds/249
- Fedora (shutil and zipfile) - 
https://buildbot.python.org/all/#/builders/449/builds/31


Please look at this, especially the Windows compile failure. I will be 
attempting 3.9.0a4 next week with 3.8.2 final.

It's a regression of a change merged yesterday:
https://bugs.python.org/issue38691

> - Fedora (shutil and zipfile) - 
> https://buildbot.python.org/all/#/builders/449/builds/31

"test_shutil fails with OSError: [Errno 28] No space left on device on
"PPC64LE Fedora Stable LTO + PGO 3.x" buildbot"
https://bugs.python.org/issue39676

It may be nice if we can revert the removal of collections aliases
before the next 3.9.0a4 (but it can also wait):

I created https://github.com/python/buildmaster-config/issues/168
"Disable Windows 7 on the Python 3.x branch".

Can someone propose a PR for that? The issue explains how to do it.

[python-committers] [RELEASE] Python 3.8.2rc2 is now available for testing

[Łukasz Langa]

Python 3.8.2rc2 is the second release candidate of the second maintenance 
release of Python 3.8. Go get it here:

https://www.python.org/downloads/release/python-382rc2/ 


Why a second release candidate?

The major reason for RC2 is that GH-16839 
 has been reverted.

The original change was supposed to fix for some edge cases in urlparse 
(numeric paths, recognizing netlocs without //; details in BPO-27657 
). Unfortunately it broke third parties 
relying on the pre-existing undefined behavior.

Sadly, the reverted fix has already been released as part of 3.8.1 (and 3.7.6 
where it’s also reverted now). As such, even though the revert is itself a bug 
fix, it is incompatible with the behavior of 3.8.1.

Please test.


Timeline

Assuming no critical problems are found prior to 2020-02-24, the currently 
scheduled release date for 3.8.2 (as well as 3.9.0 alpha 4!), no code changes 
are planned between this release candidate and the final release.

That being said, please keep in mind that this is a pre-release of 3.8.2 and as 
such its main purpose is testing.

Maintenance releases for the 3.8 series will continue at regular bi-monthly 
intervals, with 3.8.3 planned for April 2020 (during sprints at PyCon US).


What’s new?

The Python 3.8 series is the newest feature release of the Python language, and 
it contains many new features and optimizations. See the “What’s New in Python 
3.8 ” document for more 
information about features included in the 3.8 series.

Detailed information about all changes made in version 3.8.2 specifically can 
be found in its change log 
.


We hope you enjoy Python 3.8!

Thanks to all of the many volunteers who help make Python Development and these 
releases possible! Please consider supporting our efforts by volunteering 
yourself or through organization contributions to the Python Software 
Foundation.

[Steve Dower]

Windows 7 is not supported for 3.9, but the buildbots have not been 
removed/repurposed yet. They can be ignored. 




There's a bug somewhere with the owners on it.




Cheers,


Steve
