Posting this here first, though it's looking less like a Python bug and more like an environment problem, or issue with something in Ubuntu.

I'm running the regular test suite for the py3k branch and seeing this failure on Ubuntu 10.10: http://bugs.python.org/issue10094 testurllib.py fails with RuntimeError on Ubuntu 10.10 It's completely consistent. It happens with the regular test suite, or just running testurllib.py, and it does not happen with any other test afaict.

An easy way to reproduce is to have an environment variable named "PROXY":

$ PROXY=toto ./python -m test.regrtest -F test_urllib [ 1] test_urllib Warning -- os.environ was modified by test_urllib test test_urllib failed -- Traceback (most recent call last): File "/home/antoine/py3k/debug/Lib/test/test_urllib.py", line 121, in setUp for k in os.environ.keys(): File "/home/antoine/py3k/debug/Lib/_abcoll.py", line 410, in iter for key in self._mapping: File "/home/antoine/py3k/debug/Lib/os.py", line 441, in iter for key in self._data: RuntimeError: dictionary changed size during iteration

There doesn't seem to be anything really mysterious, actually. The exception message says it all :)

Regards

Antoine.
