static variables in CPython - duplicated _Py_IDENTIFIERs?
by vinay_sajip＠yahoo.co.uk 29 Sep '19

29 Sep '19

I just ran an analysis of static variable definitions in CPython code, using clang, on Ubuntu and Windows. The results should be available here: https://cpython.red-dove.com/ As I understand it, _Py_IDENTIFIER instances are supposed to hold constant strings that are used in Python - e.g. "__class__", "__dict__" and so on. I noticed that there are numerous duplicates of these - e.g. 8 instances of __name__, 11 instances of __dict__, and so on - each instance is defined as static in its source file and so completely distinct from the others. I realise the overall amount of memory used by these structures isn't large, but is there any particular benefit to having these multiple copies? The current situation seems a little untidy, at least. What would be the disadvantage of making them extern in the headers and allocating them once in some consts.c module? After all, they seem for the most part to be well-known constant strings that don't need to be encapsulated in any particular C compilation unit. Regards, Vinay Sajip

3.7.5rc1 cutoff ahead
by Ned Deily 28 Sep '19

28 Sep '19

https://discuss.python.org/t/3-7-5rc1-cutoff-ahead/2288 A reminder: it is time for the next quarterly maintenance release of Python 3.7. The cutoff for **3.7.5rc1** is scheduled for this coming Monday (2019-09-16) by the end of day AOE. Please review open issues and ensure that any that you believe need to be addressed in 3.7.5 are either resolved or marked as a **release blocker**. Any assistance you can provide in helping resolve issues will be greatly appreciated. Following the rc1 cutoff, changes merged to the 3.7 branch will be released in 3.7.6 three months from now unless you mark the issue as a release blocker prior to **3.7.5 final**, planned for release on **2019-09-30** and explain why the change should be cherry-picked into the final release. Thanks to everyone who has been helping to ensure the continued success of Python 3.7! Our users truly appreciate it and are showing their confidence in us by the rapid adoption of these latest releases. P.S. A number of core developers are participating in this year's core developer sprint taking place this week in London. So it is a good time to catch many of us in the same place at the same time (and British Summer Time, at that). https://www.python.org/dev/peps/pep-0537/ -- Ned Deily nad(a)python.org -- []

ATTENTION: Python 3.8.0rc1 is due on Monday, Sep 30th
by Łukasz Langa 27 Sep '19

27 Sep '19

Hello fellow core developers and testers, as documented in PEP 569, we're less than 72 hours away from tagging the release candidate of Python 3.8.0. Ideally we'd only need one. Sadly, at the moment we're looking rather miserable release-blocker wise: https://bugs.python.org/issue?%40action=search&%40columns=activity&%40colum… <https://bugs.python.org/issue?@action=search&@columns=activity&@columns=id&…> The buildbots look better but they're also not perfect (there's too much red in recent history): https://buildbot.python.org/all/#/grid?branch=3.8&tag=stable <https://buildbot.python.org/all/#/grid?branch=3.8&tag=stable> If you're on any of the release blockers, please work on fixing them ASAP. If you're not on any release blockers, please avoid any commits to 3.8 for the time being. The release candidate should ideally *be* 3.8.0, we don't want any untested last-minute changes. Stabilizingly y'rs - Ł

Bug in Bedevere related to detecting edited titles that add in the bpo number post-open
by Brett Cannon 24 Sep '19

24 Sep '19

https://github.com/python/bedevere/issues/192 It should get fixed sometime today or at worst tomorrow. Until then, if someone edits a title after creating a PR to add an issue number, just add the `skip issue` label and then remove it again and it will run the check.

When writing a PEP, please use the template from PEP 12
by Brett Cannon 20 Sep '19

20 Sep '19

https://www.python.org/dev/peps/pep-0012/#suggested-sections This applies even to folks who have written a PEP before as that template gets updated on occasion. For instance, there's a new copyright notice and the last couple proposed PEPs didn't catch it because they copy and pasted from old PEPs instead of using the template.
