Dear whiskers. As this PR [1] is merged, we could successfully migrate our core repo to travis-ci.com. Specially thanks to Pencheng for his prior investigation.
So all existing PRs need to be rebased from the latest master to apply the new CI environment. If you are an author of any existing PRs, please rebase them. Though migration is done, Pengcheng and my work revealed some points to improve. Travis CI was occasionally dragging and we observed many warnings about python2 deprecation. I believe we need to upgrade the version to python3 and if possible it would be great to migrate an on-prem CI environment based on Github action to accelerate the test speed. Some of the incompatibilities with python3 were also addressed by Pengcheng's former work [2]. So that would be a good starting point. -dom [1] https://github.com/apache/openwhisk/pull/5042 [2] https://github.com/apache/openwhisk/pull/5036
