[RELEASE] ACTION REQUIRED: Python 3.8.0b4 now available for testing
by Łukasz Langa Aug. 30, 2019

Aug. 30, 2019

It's time for the last beta release of Python 3.8. Go find it at: https://www.python.org/downloads/release/python-380b4/ <https://www.python.org/downloads/release/python-380b4/> This release is the last of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. The next pre-release of Python 3.8 will be 3.8.0c1, the first release candidate, currently scheduled for 2019-09-30. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.8 during the beta phase and report issues found to the Python bug tracker as soon as possible. Please note this is the last beta release, there is not much time left to identify and fix issues before the release of 3.8.0. If you were hesitating trying it out before, now is the time. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2019-09-30). Our goal is have no ABI changes after beta 3 and no code changes after 3.8.0c1, the release candidate. To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. That beta phase is coming to an end. Please test now. Please keep in mind that this is a preview release and its use is not recommended for production environments. Acknowledgments Many developers worked hard for the past four weeks to squash remaining bugs, some requiring non-obvious decisions. Many thanks to the most active, namely Raymond Hettinger, Steve Dower, Victor Stinner, Terry Jan Reedy, Serhiy Storchaka, Pablo Galindo Salgado, Tal Einat, Zackery Spytz, Ronald Oussoren, Neil Schemenauer, Inada Naoki, Christian Heimes, and Andrew Svetlov. 3.8.0 would not reach the Last Beta without you. Thank you! - Ł

Re: Announcing the new Python triage team on GitHub
by Raymond Hettinger Aug. 24, 2019

Thanks for doing this. I hope it encourages more participation. The capabilities of a triager mostly look good except for "closing PRs and issues". This is a superpower that has traditionally been reserved for more senior developers because it grants the ability to shut-down the work of another aspiring contributor. Marking someone else's suggestion as rejected is the most perilous and least fun aspect of core development. Submitters tend to expect their idea won't be rejected without a good deal of thought and expert consideration. Our bar for becoming a triager is somewhat low, so I don't think it makes sense to give the authority to reject a PR or close an issue. ISTM the primary value of having triager is to tag issues appropriately, summon the appropriate experts, and make a first pass at review and/or improvements. FWIW, the definition of the word triage is "in medical use: the assignment of degrees of urgency to wounds or illnesses to decide the order of treatment of a large number of patients or casualties." That doesn't imply making a final disposition. Put another way, the only remaining distinction between a "triager" and a "core developer" is the ability to push the "commit" button. In a way, that is the least interesting part of the process and is often a foregone conclusion by the time it happens. Raymond

Announcing the new Python triage team on GitHub
by Mariatta Aug. 21, 2019

Aug. 21, 2019

We have a new Python triage team on GitHub to help improve our workflow. GitHub has a nice table that shows what a triager can or cannot do in general: https://help.github.com/en/articles/repository-permission-levels-for-an-org… More specific roles and responsibilities of the Python triage team are described in devguide: https://devguide.python.org/triaging/#python-triage-team The responsibilities are a little different than the Developer role that we currently have on b.p.o. On GitHub, triage team members have access to triage issues and pull requests not only in CPython repo, but also all the repositories owned by Python core team, including: devguide repo and all the bots' repos. Existing b.p.o Developers are not automatically added to Python triage team, but they can opt-in and request membership. Several reasons: - we don't know if the triager is still active or not - we don't know if the triager wants the added responsibilities or not Other contributors are also welcome to request the Python triage membership. All it takes is one core developer to approve the request. The process is fully documented in https://devguide.python.org/triaging/#becoming-a-member-of-the-python-triag…, and there is an issue template for requesting membership in core-workflow https://github.com/python/core-workflow/issues/new/choose The first two triage team members are Kyle Stanley and Jeroen Demeyer.

Missing license for file Modules/ossaudiodev.c
by mihaela olteanu Aug. 21, 2019

Aug. 21, 2019

Hello, Could you please let me know what is the license for the file Modules/ossaudiodev.c ?Inside the description there is a statement :"XXX need a license statement" which creates some confusion.Can we simply disregard that statement as for the other .c files which do not have such statements?Please note that we need this information for our OSS clearance report. Thank you, Mihaela

Inline links in Misc/NEWS entries
by Kyle Stanley Aug. 20, 2019

Aug. 20, 2019

Recently, on Discuss, I created a new topic: https://discuss.python.org/t/should-news-entries-contain-documentation-link… However, many may not have the time to read the full post or don’t regularly check the core workflow category on Discuss, so I'll provide a shortened version here. During my experience thus far reviewing PRs on GitHub, I've noticed a significant degree of inconsistency when it comes to the usage of inline links with reST and Sphinx in Misc/NEWS entries. Since many of my contributions have involved documentation changes, I've familiarized myself most of the syntax. Many of the features in markup languages provide visual modifications rather than functional ones. However, with the inline markup supported by reST and processing from Sphinx, there's a functional improvement as well. For example, the usage of :func:\`<function name>\` (escaped for mailman) provides a link to the relevant docs for the function. In the context of news entries, this allows readers to click on a function, method, class, etc for more information. This can be useful if it's something they're not familiar with, or when the changes affected the docs. For those who are familiar with the structure of docs.python.org, the cross link to the docs may not seem at all necessary. However, for readers that are either newer or not familiar with the structure, they might be led astray into 2.7 docs or an entirely wrong page. This happens especially frequently when using external search engines. I'm not at all suggesting that every PR author should be required to use it or know all of the reST constructs. However, I would like for everyone to be aware of the potential usefulness of including inline links in news entries, and mention it in the devguide. Also, I would like to understand why some developers dislike including it, even when the reST syntax is provided. The majority of authors so far would add my suggestion to their PR, but there have been some that don't want anything besides plaintext in their news entry. Personally, I think it provides further inclusiveness to readers of all levels of experience and QoL at a very minimal cost.

subtype_dealloc causes segfaults on c heap type subclasses
by Eddie Elizondo Aug. 17, 2019

Aug. 17, 2019

Hi everyone, I found a bug in subtype_dealloc causing segfaults when used with C heap types. Given that it modifies the deallocation routine of every instance, I thought it was important to surface this in here as well. Also worth noting, this blocks the adoption of PEP384 in C Extension modules that depend on subclassable types. The bug and the fix are explained in detail in the PR: https://github.com/python/cpython/pull/15323

Re: [Webmaster] Python for Mac OS X Catalina
by Steve Holden Aug. 17, 2019

Aug. 17, 2019

Hi Ana, This is something that the development team are best placed to answer, and I'm sure that they'd be happy to know if there are bumps in the road coming up with Catalina. I am copying this reply to the core developer list to alert them. It would be helpful if you could make as full a report as possible via bugs.python.org. A reply-all to this email can be used to let the development team know the report reference should you do so, and the bug tracker is a better medium for such focused communication than the list. I've moved the webmaster address to Bcc to relieve it of further traffic. Good luck!
