[infra] Coverage issues

[dcharkes]

Now that we have added coverage from multiple workflows, Coveralls is forgetting the coverage from other workflows.

FFIgen CI ran last:

This is a reintroduction of #10:

It combines coverage from jobs from a single workflow but not jobs from separate workflows.

Secondly, Coveralls doesn't seem to find the source file locations:

We should either see if we can fix the setup for Coveralls, or switch to CodeCov (#70 (comment)).

The source not available problem might be because you have not signed in?

Thanks!

I wonder why one needs to be signed in to see the source code of a public repo? 🤔

I had wondered the same before! Btw the PR doesn't seem to work, I also pushed some code to trigger jnigen's CI as well, but coverall still only shows ffigen's coverage.

The flag name seems to be ignored for ffigen: https://coveralls.io/builds/64057741
But then works fine for jnigen: https://coveralls.io/builds/64057335

The only difference I can see is parallel: true and then a separate call to finish the coverage. That should not influence it.

It looks like coverage is now working as expected: #819 (comment)
