Is it still possible that the PEP 554 appears in Python 3.9?

[mkueh]

The main page still says "still hopeful for Python 3.9" but the time window for that is already closed, right?

FYI, I have a backport for PEP554, works on 3.8 / 3.9 : https://github.com/aisk/backports.interpreters

Would guess not based on PR ( python/peps#1394 ), but would be happy to be wrong 🙂

@mkueh The target was moved from 3.9 to 3.10 back in May as stated in this email on python-dev, with the aim being to have a per-interpreter GIL by then :)

You may be interested in the wider email discussions around that time (there were a couple of other threads, you can search "pep 554" to find them):

• PEP 554 for 3.9 or 3.10?
• Latest PEP 554 updates

@LewisGaul, do you happen to know where the per-interpreter GIL work is being tracked?

[LewisGaul]

@jakirkham I think this is still the main centralised place for tracking the subinterpreter work, I'm not personally aware of there being a lot of movement on the project currently, perhaps we can expect to see a bit more happening closer to release of 3.10 :) That's not to say there wouldn't be room for people to help out before then! Perhaps Eric will be able to give more of an update at some point, but I can understand there being a break in activity after the push for 3.9.

I've just been made aware of Victor Stinner's page tracking subinterpreter work: https://pythondev.readthedocs.io/subinterpreters.html

Hey @ericsnowcurrently I would love to contribute to this and would really appreciate some guidance, sorry I contacted you this way I couldn't find any other... Thanks in advance!

I would suggest closing this issue - the answer is that PEP 554 will not appear in 3.9 (which has now been released), and the target is 3.10.
