[New-bugs-announce] [issue15912] Intermittent import failure

[Jean-Paul Calderone]

New submission from Jean-Paul Calderone:

The attached unit test fails with an ImportError... sometimes.  Here's a little blob of shell that seems to make the failure come up more quickly:

while ~/Projects/cpython/3.3/python -m unittest -v test_broken_import; do
    rm -rf test_broken_import;
    rm -rf __pycache__/;
done

An example of the output when I run it:


exarkun at top:/tmp$ while ~/Projects/cpython/3.3/python -m unittest -v test_broken_import_minimal; do rm -rf test_broken_import; rm -rf __pycache__/; done
