[issue24153] threading/multiprocessing tests fail on chromebook under crouton generated chroots

[Davin Potts]

Davin Potts added the comment:

Ned's comments summarize this nicely.  It's been 7 months without a response 
from the OP and given the nature of the OP's environment (use of crouton on a 
chromebook) it strongly supports the theory that the OP simply had insufficient 
resources to run the full tests.

[issue24153] threading/multiprocessing tests fail on chromebook under crouton generated chroots

[Ned Deily]

Ned Deily added the comment:

The failures seem pretty clear:

OSError: [Errno 28] No space left on device

Are you allocating enough disk space in the chrooted environments?  The amount 
of free space needed to run all the tests varies by platform, by architecture, 
by test options selected, etc, and by file system type (see, for example, 
Issue23953).  I don't know that we have any rough guidelines for free space; 
you may have to experiment and you could try excluding largefile tests:

./python -m test -uall,-largefile [...]

[issue24153] threading/multiprocessing tests fail on chromebook under crouton generated chroots

[Ryan Shupe]

New submission from Ryan Shupe:

I set up my Asus chromebook c200 with crouton and installed two chroot 
environments under the trusty release. In one I built and ran the tests for 
Python 3.5.0a4+

See stacktrace of resulting error:
