feat(ci): use GitHub Actions for CI/CD

[paul-marechal]

Replace .travis.yml with GitHub Actions.

Splitting scripts was needed to correctly run in CI:

• yarn now only install deps and builds example apps.
• yarn lint lints our TypeScript sources.

THEIA_SKIP_BUILD=1 can be enabled to only install deps when doing yarn.

Notes:

I skipped the flakiest tests, but it seems like some are still causing trouble. Feel free to restart the jobs.

@kittaakos just a heads up that I think this PR is ready for review.

What's done:

• Install, lint, build, and test.
• Publishing next? Wasn't able to test, and I think we are missing a secret (NPM_TOKEN).

What's missing:

• Caching of node_modules.
• Publishing the gh_pages.

I think the missing parts can be added later, but feel free to push on this branch to add things you think should be there.

Thank you for preparing it, @marechal-p. There are a few things I do not really like: such as unnecessary configs, changed npm scripts, hacks, and the publish build does not wait. Here is my proposal. There is one thing I do not understand, the macOS build fails for some reason.

$ yarn build && run lint && run build "@theia/example-*" --stream --parallel
$ tsc -b configs/root-compilation.tsconfig.json
ERR! lerna Invalid command!
ERR! lerna Pass --help to see all available commands and options.

Here is the build without the macOS image, and here is with macOS.

I also updated the issue for this PR: we do the codec thingy after the tsc build. Is that correct? I guess you are the one who has the most experience with the code logic.

There is one thing I do not understand, the macOS build fails for some reason.

There is something odd with the theia-run.js module when manipulating the proceee.argv:

Here are the outputs from Linux and macOS:

macOS:

process.argv: ["/Users/runner/hostedtoolcache/node/12.19.0/x64/bin/node","/Users/runner/work/theia/theia/node_modules/.bin/run","lint"]

modified process.argv: ["/Users/runner/hostedtoolcache/node/12.19.0/x64/bin/node","run","/Users/runner/work/theia/theia/node_modules/.bin/run","--scope","lint"]

Linux:

process.argv: ["/opt/hostedtoolcache/node/12.19.0/x64/bin/node","/home/runner/work/theia/theia/node_modules/.bin/run","lint"]

Here is an alternative solution: #8780

There is something odd with the theia-run.js module when manipulating the proceee.argv:

Yes and since I did not have access to a mac I avoided this issue by not using theia-run.js. I see that you have a fix, nice.

we do the codec thingy after the tsc build. Is that correct?

It happens on postinstall for the @theia/electron package. From the commit history, we had to explicitly call the ffmepg test scripts because the @theia/electron package was being cached, so postinstall did not run somehow? At any rate, the tests should happen when we do yarn on the monorepo.

Closing in favor of #8780
