[BEAM-10702, BEAM-10757] Cherrypick #12571: Do not implicitly decompress artifacts

[jkff]

Also adds a Julia set test on portable local runner, which uses a
setup.py and hence exercises the artifact staging codepath.

This is a squashed cherrypick of #12571 + a change to CHANGES.md.

I also added the LICENSE for enum34 to manual_licenses as the original repo is down. I took the license from somebody's backup: https://github.com/jamespharaoh/python-enum34

Hmm all the builds are pending apparently cause something's going on with Jenkins - eg https://ci-beam.apache.org/job/beam_PreCommit_Portable_Python_Commit/ says "Jenkins is going to shut down". Haven't seen this before. Do I need to do anything?

[tvalentyn]

not sure, perhaps related to https://issues.apache.org/jira/browse/BEAM-10751.

[tvalentyn]

retest this please

[youngoli]

This all looks good, thanks Eugene! I'll merge it in after the tests pass, assuming the Python Precommit issue is fixed.

[tvalentyn]

@youngoli note that precommit IT tests will fail until Dataflow containers for the release branch are built. This change does not affect Dataflow codepath.

[jkff]

retest this please

[jkff]

Retesting cause https://ci-beam.apache.org/job/beam_PreCommit_Portable_Python_Commit/12849/consoleFull shows an error in :sdks:python:container:py2:docker but it passes when I run this target locally.

[tvalentyn]

Run PythonDocker PreCommit

We would need to change how we fetch the license for enum34. This must be blocking precommits now on master as well.

[tvalentyn]

@ethanfurman FYI, the project homepage link (https://bitbucket.org/stoneleaf/enum34) at https://pypi.org/project/enum34/ is now broken.

[jkff]

Yeah it'll have to be added to manual_licenses. I'll do that in this PR in a moment.

[tvalentyn]

Opened https://issues.apache.org/jira/browse/BEAM-10757

[tvalentyn]

thanks, @jkff, will assign that to you then.

[tvalentyn]

did you git add the LICENSE file? Also, it would be great if you send a PR for master with these commit(s). Thanks!

[jkff]

Oops, added now, thanks! Will send a separate PR to master. Do you prefer if I remove it from here?

[tvalentyn]

Feel free to keep it here as well, we can merge these into 2.24.0 as two separate commits. Thanks!

[jkff]

#12624

[jkff]

The PythonDocs precommit is failing because it was only added at master in #12575 and isn't present in the 2.24 branch.

[youngoli]

Ack. The Python Precommit is also only failing because of BEAM-10697, so that's not an issue.

I'm wondering about the PVR_Flink PreCommit though, I haven't seen that error below. Flake maybe? (Link)

[youngoli]

Run Python2_PVR_Flink PreCommit

[jkff]

Alright, we now have 2 failing precommits both due to known issues: Python with BEAM-10697, and PythonDocs because it doesn't exist at 2.24. Looks like BEAM-10697 is resolved, but not cherrypicked into 2.24. @youngoli Do you want to ignore it for this PR or should we wait for someone to cherrypick a fix and rebase on that?

[youngoli]

Yeah, I think it's safe to ignore the Python precommit error here. I'll merge it in.
