PEP 588 updates
by Mariatta 07 Aug '19

07 Aug '19

I've updated the text of PEP 588 (https://www.python.org/dev/peps/pep-0588/) with several items under "Migration Plan" section: - Hire a professional project manager to help ensure the success of the project. - Create a playground issue tracker on GitHub to experiment and test the new workflow - The work on new CLA host is currently stalled. (more details: https://discuss.python.org/t/cla-assistant-is-no-go/2066) - We've created a new Python Triage team, taking advantage of GitHub's beta Triage role. We need a better guideline/criteria on how to promote people to the Python triage team. - A test repo containing proposed GitHub labels have been created by Carol Willing. It can be reviewed at: https://github.com/willingc/test-581/labels Feedback are welcome. I would suggest discussing the labels in Discourse <https://discuss.python.org/> under core-workflow category. - we should create a separate branch on GitHub with info about the new workflow. This should be done ahead of the actual migration, not after. Please re-read PEP 588 in its entirety. Any questions or concerns about PEP 588 can be discussed here in python-dev, or Discourse under core-workflow category. (https://discuss.python.org/c/core-workflow) Thanks. Mariatta ᐧ

Is "%zd" format is portable now?
by Inada Naoki 06 Aug '19

06 Aug '19

Hi, snprintf() in VC 2010 had not supported "%zd" format. So we can not use it in PyOS_snprintf, PySys_WriteStdout, etc... But VC supports "%zd" format since (at least) VC 2015. See https://docs.microsoft.com/en-us/cpp/c-runtime-library/format-specification… "%zd" is standard C99 feature. Can we assume it is portable for now? Regards, -- Inada Naoki <songofacandy(a)gmail.com>

Collecting stories about beginning contribution
by Tal Einat 01 Aug '19

01 Aug '19

Hi everyone, (FYI, I'm cross-posting this from core-mentorship. If you'd like to reply, please do so there.) Following the recent discussion on core-mentorship about beginning contribution, the difficulties it entails and how to improve the situation, I'd like to start a process of improving the situation. As a first step, I'd like to collect as many stories about beginning to contribute to Python. This includes stories about failures to do so; in fact, those would be most useful! I'm intentionally leaving this very open; I'd like to hear anything people have to tell about their experiences, with as little guidance as possible. Specifically, at this point, I'm not (yet) looking for specific suggestions for how to improve the situation. So, following Guido's call (on core-mentorship) to publicly post such stories, please help us collect as many such accounts as possible! Post your own stories, and more importantly, reach out to others who could share their own stories and ask them to do so! Those who feel that posting publicly would require too much work, or just don't feel comfortable doing so, are invited to write to me personally; I'll use the information anonymously if asked to. Regards, - Tal Einat
