Interesting, looks like the warnings from issue 19694 *weren't* the cause
of the bad return code - something else is failing. I should have some time
to investigate tomorrow afternoon, but it will consist of trying to improve
the diagnostic output from the tests. If we can get the buildbot owners
involved, that could help a lot (1 am here, I'm about to go to sleep).

Bumping priority and adding Larry to the nosy list

Checking the latest results from the systems listed above:

Ubuntu LTS still failing due to this: http://buildbot.python.org/all/builders/AMD64%20Ubuntu%20LTS%203.x/builds/3213/steps/test/logs/stdio (added Łukasz to nosy list)

x86 OpenIndiana still failing due to this: http://buildbot.python.org/all/builders/x86%20OpenIndiana%203.x/builds/7123/steps/test/logs/stdio (added Jesús to the nosy list)

AMD64 OpenIndiana machine is still failing, but not due to this (test_tarfile failure): http://buildbot.python.org/all/builders/AMD64%20OpenIndiana%203.x/builds/6972/steps/test/logs/stdio

Windows 7 failure is in test_tarfile: http://buildbot.python.org/all/builders/AMD64%20Windows7%20SP1%203.x/builds/3410/steps/test/logs/stdio

Windows XP failure was a build issue for the new _opcode module: http://buildbot.python.org/all/builders/x86%20XP-4%203.x/builds/9651/steps/test/logs/stdio

Solaris (not a stable buildbot) had slightly different symptoms and a few other errors: http://buildbot.python.org/all/builders/AMD64%20Solaris%2011%20%5BSB%5D%203.x/builds/2216/steps/test/logs/stdio

AIX has lots of issues, include some where features pip is relying on don't work: http://buildbot.python.org/all/builders/PPC64%20AIX%203.x/builds/1127/steps/test/logs/stdio

Christian, that was my original theory in issue 19694 (since that box runs with PYTHONWARNINGS=d set), but it doesn't look like it is the problem, since running in isolated mode didn't fix the issue (although it did suppress the warnings).
msg204162 - (view) Author: Alyssa Coghlan (ncoghlan) * (Python committer) Date: 2013-11-24 02:17
That specific stack trace is from the commit where I inadvertently reverted the isolated mode fix - the pip installation test is always run with PYTHONWARNINGS=e now to make sure it will fail in non-isolated mode.

test_venv is now passing on 3.x OpenIndiana: http://buildbot.python.org/all/builders/x86%20OpenIndiana%203.x/builds/7129/steps/test/logs/stdio

Ubuntu LTS buildbot is still unhappy: http://buildbot.python.org/all/builders/AMD64%20Ubuntu%20LTS%203.x/builds/3221/steps/test/logs/stdio

And looking at the environment armed with the improved error details, this is likely the culprit:

  PIP_REQUIRE_VIRTUALENV=true

I'll hack the test to delete it from the subprocess invocation for now, but I think there's a pip bug here: -E (and, equivalently, -I) should likely cause pip to ignore *its* environment variables as well.

test_venv appears to be green on all the stable buildbots now.

However, blocking PIP_REQUIRE_VIRTUALENV in the test probably isn't the right place  for workaround - resolution in venv or ensurepip would be more appropriate.
msg204313 - (view) Author: Alyssa Coghlan (ncoghlan) * (Python committer) Date: 2013-11-25 08:41
Hmm, this may also indicate a bug in pip's "require virtualenv" handling.
Why isn't it detecting that sys.prefix and sys.base_prefix are different,
and hence it *is* running in a venv created virtual environment?

1358 (failing to detect native virtual environments) will be resolved upstream, but for 1359 (telling pip to ignore the environment variables), I've decided I agree with Paul's suggestion on the pip issue that it makes sense for venv to just strip all environment variables starting with "PIP_" from the environment passed to the subprocess.

This suggests both that the setting didn't get cleared as expected *and* that pip 1.5rc2 still failed to detect the pyvenv created virtual environment.
