Should we drop Python 2.2 support in Subversion head for Twisted 2.2?
I consider this issue resolved, given the lack of response for people wanting 2.2 support. The buildslave for 2.2 should be taken down and Twisted trunk should be considered fair for 2.3-only features.
Lack of interest in a change doesn't dictate that the change be made. I didn't hear anyone come out against the change _or_ for it.
If it will help, I'll throw in against dropping 2.2 support. Neither 2.3 nor 2.4 introduce any compelling new features.
You are confused. At least two people were *for* dropping 2.2 support in this thread, and nobody was against it. I'm pretty sure several others have been for dropping it on IRC, as well.
Confused, perhaps. Or perhaps their positions were voiced with such limited enthusiasm I just forgot about them :)
I have seen people several times commit code that requires 2.3, realize that the buildbot failed, and replace the code with a more complicated version (didn't you do this recently yourself, Jp?). I personally find it harder and harder to test 2.2, as finding an installation of 2.2 is getting rarer these days. To unshamedly list features from the "What's new in Python 2.3" article:
Yea, I've probably done this, and I've seen a few other people do it too. Fortunately, buildbot's new "build a branch" feature should help resolve this problem. Anyone can try out their code on any of Twisted's supported platforms before merging it into trunk.
- Sets - Proper booleans (2.2.0 didn't even have the "True" and "False" constants) - enumerate - csv - generators without __future__ - sum - callable types - horrible obscure Python2.2-only bugs and semantics changes gone - str in str - arguments-to-strip
These are all pretty minor (apart from the "horrible obscure" things), but the sum() of them adds up to a lot of annoyance in support when no users have actually thrown in for it.
It's a pretty good list, I must admit. But I wonder what the specific gains to Twisted will be. Just having a list of things Python 2.3 can do that Python 2.2 cannot does not seem compelling to me. Jean-Paul
