Arvados

Test run at: https://ci.curoverse.com/job/developer-run-tests/87/
Updates: fee8873

Added --version to the following commands:

• arv-ls
• arv-put
• arv-ws
• arv-get
• arv-copy
• arv-run
• arv-normalize
• arv-keepdocker
• arv-mount
• arvados-node-manager

Also added tests to confirm the new argument.

Looks like we need to add setuptools dependency to our deb/rpm packages, like we did for arvados-cwl-runner, in order to use this mechanism.

I guess it also makes sense to add setuptools to install_requires in setup.py.

Tried in wheezy, and found that the wheezy version of python-setuptools (0.6.24-1) does work, so at least we don't have to build another new package.

I'm very wary of using multiprocessing in tests, especially arv-put which definitely uses threading. Combining multiprocessing and threading in Python seems to be a recipe for disaster (or at least unbounded debugging efforts). Can we get what we need just by catching SystemExit? In source:services/fuse/tests/test_command_args.py it looks like this works for argparse. Failing that, maybe subprocess?

Test suite run at: https://ci.curoverse.com/job/developer-run-tests/88/

• Changed those tests depending on multiprocessing to use a context manager stderr/stdout redirector and a SystemExit catching assertion as requested.
• Added setuptools dependencies on package building script and setup.py install_require definitions.
