I tried out Twisted's test suite with a version of Python built from SVN trunk
today and ran into a few problems. First, the test suite hung indefinitely
using all available CPU time. This apparently was due to a change in the
behavior of __import__: in Python 2.4, __import__('') raises a ValueError; in
Python 2.5, it returns None.
Once I hacked around this, the test suite ran to completion, though with over
fifty failures. Some of these appear to be related to the conversion of the
exception hierarchy to new-style classes, but I have not yet had a chance to
examine them closely.
Once I do have time to track down specifics, I'll file tickets as appropriate.
For now I just wanted to point out the one detail I have tracked down, and give
a heads up that there are likely some more to come.
Of course anyone who is interested can run the Twisted test suite very easily
and take a look at the failures themselves (if you have Twisted installed,
"trial twisted" will do it).
