Description (last modified by exarkun)

The drop-upload tests added in 32a7717205ed824a create a subdirectory under _trial_temp that has a non-ASCII name (locāl_dir). On Windows, this causes an error subsequent builds when buildbot tries to delete the "workdir" for the build, which contains _trial_temp. This seems to happen because it ASCIIfies the name to "local_dir" when trying to change its permissions to ensure it is deleteable.

An ugly workaround would be for the tests to delete any non-ASCII directories they create. This should really be fixed in buildbot, though.

The traceback is:

  • Milestone changed from 1.9.0 to eventually
  • Priority changed from critical to major

This is strictly speaking invalid now for Tahoe-LAFS, since the actual bug is in buildbot and we've worked around the immediate problem. However, when buildbot is fixed we'll need to decide whether to remove the workaround.

In the meantime, other tests that create non-ASCII directory names should mix in NonASCIIPathMixin from src/allmydata/test/common_util.py and use self.mkdir_nonascii.

FWIW, there is a class in fileutil.py that does something similar: src/allmydata/util/fileutil.py@4957#L90. There is also a more featureful version of that class in pyutil: pyutil/fileutil.py.

Replying to zooko:

NamedTemporaryDirectory deletes the directory tree when the NamedTemporaryDirectory object is __del__'d, which is the wrong time. We need to delete it when the test has finished (which, because of Deferreds, will be some time after the test method returns). There's no simpler way to do this than using addCleanup, as the current code does.

For future reference, you can also invoke the NamedTemporaryDirectory object's shutdown method at a specific time if desired.
