Running PyPy3-3.5-5.7.1-beta from pyenv on Ubuntu 14.04 (Travis CI) for the gevent unit tests. When there is code that uses TestCase.assertRaises, the following stack trace may be raised (

    File "", line 146, in test_set_exception
      self.assertRaises(greentest.ExpectedException, s1.get)
    File "/home/travis/.runtimes/versions/pypy3.5_571/lib-python/3/unittest/", line 728, in assertRaises
      return context.handle('assertRaises', args, kwargs)
    File "/home/travis/.runtimes/versions/pypy3.5_571/lib-python/3/unittest/", line 177, in handle
      callable_obj(*args, **kwargs)
    File "/home/travis/.runtimes/versions/pypy3.5_571/lib-python/3/unittest/", line 201, in __exit__
    File "/home/travis/.runtimes/versions/pypy3.5_571/lib-python/3/", line 216, in clear_frames
  AttributeError: 'Frame' object has no attribute 'clear'

The docs indicated that clear_frames was added in 3.4 and the call from unittest was added in issue 9815 slightly later.

(Apologies if this is a known issue, if so I didn't find it anywhere.)

    Argh, sorry. I checked for a clear method on the frame, but it turned out I was still checking in 3.3.5 (turns out it's easy to transpose or misread 3.3.5 and 3.5.3). I do see a clear method in 3.5.3.

    Given that, I'm pretty sure I see what's happening now.
