If it’s too much for a micro release call it 2.8 or 2.9 or something and give it a super limited scope. Proposals like modifying the sys.path to opt into the backported things or having an official unofficial stdlib just adds more things downstream users have to actually test against and more possible configurations or Pythons. Right now users have a singular method for determining what the runtime environment looks like for Python, the version. There are processes around selecting different Python versions for things, upgrading etc. This isn’t a new thing for users. Suddenly having to mess with PYTHONPATH or having to figure out if their distro used the “official stdlib” or the “official unofficial stdlib” just adds massive confusion. Things like ssl3 etc are “ok” but less than optimal IMO because one of the benefits of adding SSLContext and such to Python 2.x is that you can write code that works in 2.x and 3.x without having to special case 2.7.7 or 2.8 or whatever. However if you just add ssl3 then now you have a third path through the code that you have to deal with. > > -Barry > _______________________________________________ > Python-Dev mailing list > Python-Dev@python.org > https://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: > https://mail.python.org/mailman/options/python-dev/donald%40stufft.io ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
