New submission from STINNER Victor: I added Lib/test/bisect.py in the commit d7955b8196578306e9d86f6c61c9cb3ee72edab0, bpo-29512.
When a test is loaded by Lib/test/regrtest.py when regrtest.py runs with "python -m test", test files like Lib/test/test_bisect.py are created with __package__ = ['test']. In this case, "import bisect" loads Lib/test/bisect.py rather than Lib/bisect.py. For test_bisect.py, I worked around the issue using "from __future__ import absolute_import". But then I saw this bug: http://buildbot.python.org/all/builders/AMD64%20FreeBSD%20CURRENT%20Non-Debug%202.7/builds/159/steps/test/logs/stdio Run tests in parallel using 2 child processes (...) 0:02:41 [144/403/1] test_multiprocessing failed test test_multiprocessing failed -- Traceback (most recent call last): File "/usr/home/buildbot/python/2.7.koobs-freebsd-current.nondebug/build/Lib/test/test_multiprocessing.py", line 1669, in test_connection self.assertEqual(poll(TIMEOUT1), True) AssertionError: False != True (...)
