This is a timeout issue, probably encountered on a slow machine. Checked in revision 85964 increasing the default timeout to cater to slower machines. However, I also see that the timeout mechanism used by barrier isn't very robust. I'll submit a patch with a suggested change soon. |

I also get a failure here: ====================================================================== FAIL: test_default_timeout (test.test_threading.BarrierTests) ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/antoine/py3k/__svn__/Lib/test/lock_tests.py", line 784, in test_default_timeout self.run_threads(f) File "/home/antoine/py3k/__svn__/Lib/test/lock_tests.py", line 615, in run_threads f() File "/home/antoine/py3k/__svn__/Lib/test/lock_tests.py", line 783, in f self.assertRaises(threading.BrokenBarrierError, self.barrier.wait) AssertionError: BrokenBarrierError not raised by wait |

FWIW, my snow leopard slave isn't slow at all so I doubt there's a timeout related to machine speed going on here, as its failing thus: test test_threading failed -- Traceback (most recent call last): File "/Users/pythonbuildbot/buildarea/3.x.hansen-osx-x86/build/Lib/test/lock_tests.py", line 784, in test_default_timeout self.run_threads(f) File "/Users/pythonbuildbot/buildarea/3.x.hansen-osx-x86/build/Lib/test/lock_tests.py", line 615, in run_threads f() File "/Users/pythonbuildbot/buildarea/3.x.hansen-osx-x86/build/Lib/test/lock_tests.py", line 783, in f self.assertRaises(threading.BrokenBarrierError, self.barrier.wait) AssertionError: BrokenBarrierError not raised by wait Its actually a really spammy sort of failure with a lot of errors before it, which may or may not shed more light on the situation: http://www.python.org/dev//buildbot/3.x.stable/builders/x86%20Snow%20Leopard%203.x/builds/267/steps/test/logs/stdio This was r85883, so after the increase in the timeout. |

Silly me, changing the default timeout invalidated the unittest for it. Fixed in revision 86018 |

Is this issue still valid? The last comment seems to indicate that the issue is fixed and could be closed. |
