Handle migration away from travis-ci.org

[mpenkov]

They are expecting projects to migrate from travis-ci.org to travis-ci.com. It looks like a free process for open-source projects.

We should consider whether to continue using Travis (and move to travis-ci.com) or use the opportunity to migrate everything possible to GitHub Actions.

We probably can't leave Travis entirely, because they support some platforms that GHA does not (IIRC).

What are we using Travis for now?

I thought it was already gone entirely, because GHA can build all the wheels we need (incl. Windows).

[mpenkov]

Right now the gensim-wheels repo is entirely Travis-backed. I'd have to search through past discussions to find the cases that Travis covers that GHA doesn't.

@piskvorky Can you please perform the migration process detailed here? The organization owner for RaRe-Technologies needs to do it.

[piskvorky]

OK. The authentication / migration was a mess. I think I did all the steps, working around various errors and inconsistencies in the documentation.

In the end I managed to migrate: https://travis-ci.com/github/RaRe-Technologies/gensim/settings

Is that it, or anything else needed by me?

[mpenkov]

Thanks @piskvorky, that looks sufficient.

@janaknat We migrated to .com, but there are still problems. Can you please have a look?

[piskvorky]

Hm, is this experimentation happening over the main branch? Visible to all visitors?

Doing it "privately" would be preferred, if possible.

[mpenkov]

OK, I will disable the build on the develop branch while we work this out.

My expectation was that the build pass (because of the previous history of the PR), but it appears there's still some work to be done.

[mpenkov]

The migration is complete, so I'm closing this ticket. @janaknat and I will deal with the failing Travis build in a separate ticket.
