nondeterministic failure of test_system.SystemTest.test_upload_and_download_random_key

Description

This happened once with r4850 (from tarball) on Windows Vista 32-bit: 

[FAIL]: allmydata.test.test_system.SystemTest.test_upload_and_download_random_key

Traceback (most recent call last):
  File "d:\tahoe\allmydata-tahoe-1.8.0-r4850\allmydata-tahoe-1.8.0-r4850\src\allmydata\test\test_system.py", line 330, in _uploaded
    self.failUnless(isinstance(bytes_sent, (int, long)), bytes_sent)
twisted.trial.unittest.FailTest: None

I cannot reproduce it. The machine was bogged down at the time, so it might be a timing-related race condition.

Perhaps related: #846.

Replying to zooko:

Perhaps related: #846.

Probably not, since this is looks like a race condition, and #846 is looks like a deadlock datalock or lost-signal bug.

  • Resolution set to duplicate
  • Status changed from new to closed

Probable duplicate of #1084. (I even reported both tickets and didn't notice, sigh.)
