Exception: Cannot locate xUnit report / IOError: [Errno 21] Is a directory

Like #724, but the circumstantial evidence points are a different root cause:

See the following TravisCI tests from the same tool commit https://github.com/peterjc/galaxy_blast/commit/3095f1909c6d8975aa05dc3b0d3350579aa7fba3 run as TravisCI cron jobs:

• https://travis-ci.org/peterjc/galaxy_blast/builds/555896113 (failed with Galaxy dev branch, approx 8 July 2019)

Same error+exception happening when running locally (planemo test on galaxy dev branch). No issue when running on release_19.05. I tried removing *pyc files as per https://github.com/galaxyproject/planemo/issues/724#issuecomment-329799172 - which did not fix it. I'm looking into it...

[jdavcs]

Here's why the IOError happens: This line: https://github.com/galaxyproject/galaxy/blob/dev/lib/galaxy/tools/data_manager/manager.py#L48 expects xml_filename to be a path to a file. If the file does not exist, an exception is not raised (it's expected behavior). However, when galaxy is managed by planemo, xml_filename is a directory name, so e.errno is 21 (vs 2), and an exception is raised. This works under release_19.05 because it has less stricter exception handling than dev: https://github.com/galaxyproject/galaxy/blob/release_19.05/lib/galaxy/tools/data_manager/manager.py#L44

I don't have a solution yet, but I should have one soon.

ping @natefoo : I believe the following commit is 3 years old, but was only recently merged, which is why the issue never surfaced? https://github.com/galaxyproject/galaxy/commit/280d2e3e627b3796630d1588cd4af9202dd6c8fe#diff-849c0107be4d923c00577caf4f84a1c5R38

@ic4f yeah that was part of the 4-year-old installable Galaxy PR.

I cannot reproduce the xUnit error anymore (running on a Mac, Planemo runs on python 2.7.10 and 3.7.3; Galaxy on 2.7.10, dev branch. I tried both existing installs (with --galaxy_root) and a clean install; in all cases I did not switch branches). I only see a bad file descriptor error, which is not really a thing (discussed here: https://github.com/galaxyproject/planemo/issues/752).

On a side note, the twobit.loc error (https://github.com/galaxyproject/planemo/issues/679), which was present, has disappeared too.

@jmchilton I don't know Planemo well enough to dig any deeper at this point, so I'm leaving this as is. Tests run (at least on my machine).

Also failing on my MIRA repository, with a weekly cron test, see:

https://travis-ci.org/peterjc/galaxy_mira/builds

e.g. 2 months ago passed:

https://travis-ci.org/peterjc/galaxy_mira/builds/552876215

The next week it failed:

https://travis-ci.org/peterjc/galaxy_mira/builds/555897289

There doesn't seem to be an easy way to get the date from a TravisCI build...
