Don't Use Python 2.5 Just Yet

... especially if you use Windows.

A few people installing Python for Windows just asked me if they should be using Python 2.5 or 2.4. I was unpleasantly surprised to recall it should be the latter. There's no release of Twisted that works with Python 2.5 yet. Not only that, but with Twisted trunk, although many 2.5 issues have been fixed, there are still some problems with the way that the command line tools start up on Windows which makes it impossible to even run the tests, let alone see whether they succeed.

You can keep track of this by looking at the Twisted buildbots page and the "win32-py2.5-select" buildbot in particular.

For now, though, if you want to use Twisted on Windows, you'll need Python 2.4.4. You can download it from the 2.4.4 release page on

Are there issues that should be addressed for 2.5.1? Are there SF (sorry, we're working on replacing it) bugs open for them? Or is it Twisted<->Python2.5 problems?

I believe that Python is working as intended, and these are unresolved issues with the WindowsError conversion. I don't really have enough time to look into this myself, it was already a project of several weeks for others to port Twisted to Python 2.5 anyway. Mainly I just know that it doesn't work.

I'm definitely looking forward to when Pybots can prevent situations like these.
