Explicitly included jobs are being excluded?

Hi,

We’re building branches and PRs on three platforms: macOS, Linux with gcc 6 and Linux with gcc 7.

• Travis builds: https://travis-ci.org/appleseedhq/appleseed

• Top-level .travis.yml script: https://github.com/appleseedhq/appleseed/blob/master/.travis.yml

• Linux build script: https://github.com/appleseedhq/appleseed/blob/master/scripts/travis/build-linux.sh

For three days now, both Linux builds are no longer being executed:

• Here is the last master build that proceeded on all platforms (but failed on macOS for other known reasons), dated February 26th (four days ago):
  https://travis-ci.org/appleseedhq/appleseed/builds/655239028

• The next master build (latest at the time of writing, started half an hour ago) is not proceeding on Linux:
  https://travis-ci.org/appleseedhq/appleseed/builds/656897628

• Same thing for PRs: the last PR that was built on all three platforms was four days ago:
  https://travis-ci.org/appleseedhq/appleseed/builds/655493712

• And the very next PR build was again only executed on macOS:
  https://travis-ci.org/appleseedhq/appleseed/builds/655651831

Any idea?

We’ve simplified our .travis.yml file and it looks like it’s working now:

travis tweaks

Was our issue that we were both including and excluding Linux builds, and that the outcome was somehow implementation-defined (and something in the infrastructure changed three days ago)?

When configuration validation is on, environment variable definition order may change

We are rolling out the configuration validator to more and more repositories.

Yes, your exclude: clauses exclude all Linux jobs. Previously, it had no effect on explicitly included jobs and now, it has.

It’s actually undocumented in Build Matrix - Travis CI whether include: or exclude: takes precedence. So yes,

the outcome was somehow implementation-defined

Awesome, thanks for the info!
