The "event log" in question was never useful in our test systems (and
hasn't been used for anything real since 2014). I'm not sure how we
ended up with in the CI configuration.
This change makes it so if focal backend job fails the bionic
backend and frontend jobs keeps running. Previously, it failed both
of the jobs if one failed. This is expected since typically matrix
is used to run sames tests on multiple versions and such but our use
case is bit more than that.
This is a fine solution short-term until github implements the
yaml anchors support. The limitation of this method is that we
cannot re-use most of the steps again for production install test
builds.
Thanks, Anders for this solution.
Verifying everything is migrated correctly is a pain. This script
ensures everything is done correctly (previous commit message
contains explainations for the steps being ignored if; in case
of github-actions steps they are ignored because they are actions
specific):
"""
This script prints out the ignore steps first. Then
prints out each step of both circle and actions side-by-side.
One step is out of order for bionic but verfying correction is
still easier. Format:
Actions: Install dependencies
Circle CI: install dependencies

Some noteable diffrence from circleci:
- We upgrade git to newer version (reason explained in comments)
- We set HOME to /home/github (also explained in comments)
- Adjust permissions (... comments)
- Minor changes to step names and cache keys.
- We don't need to port the save_cache steps they are done
automatically in actions. And, we did not port the
store_test_results step which is circleci specific.
- We didn't port the notify_failure step yet (see the TODO).
