[Buildbot-devel] Test failure on trunk (buildbot.test.test_slavecommand.ShellPTY.testInterrupt1)

[Greg Ward]

I just grabbed the latest Buildbot trunk from
http://buildbot.sf.net/darcs-repos/trunk and ran the tests.  One test
failed:

[ERROR]: buildbot.test.test_slavecommand.ShellPTY.testInterrupt1

Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/twisted/internet/selectreactor.py",
line 139, in _doReadOrWrite
    why = getattr(selectable, method)()
  File "/usr/lib/python2.5/site-packages/twisted/internet/abstract.py",
line 113, in doWrite
    l = self.writeSomeData(self.dataBuffer)
  File "/usr/lib/python2.5/site-packages/twisted/internet/process.py",
line 879, in writeSomeData
    return os.write(self.fd, data)
exceptions.OSError: [Errno 4] Interrupted system call

This looks like an intermittent failure: I'm now running "trial
buildbot.test.test_slavecommand.ShellPTY" in a loop, and the failure
has not repeated. Still, I thought someone should know about this.
(I'm on the trail of another bug, so I'm going to put this failure
aside for now.  Maaaaaybe I'll get back to it later, but no promises!)
