gitlab is not running the special lint when is a pull request

[moylop260]

Travis set the following environment variables

• TRAVIS_PULL_REQUEST - The pull request number if the current job is a pull request, “false” if it’s not a pull request.
• TRAVIS_BRANCH - this is the name of the branch targeted by the pull request. E.g. 11.0

Gitlab works a little different and then these checks are not emitted.

Differences between gitlab and github:

• If there is a PR from vauxoo-dev:11.0-devx-moy to vauxoo:11.0 the repository cloned is: git clone vauxoo and in order to get the PR commits uses the refs defined by github: git fetch -p origin +refs/pull/*/head:refs/pull/origin/* after that creates a checkout to pull/origin/${TRAVIS_PULL_REQUEST}

• gitlab creates the pipeline before to create a MR then I think that the remote of the target repository is not defined yet and is not cloned the target repo. (I think so...)

Then maybe we will need to define a environment variable (or use one defined from gitlab) in order to add the remote to target branch. Same case for the target branch.

@ruiztulio Any help is welcome here

@moylop260 As for the TRAVIS_BRANCH there is a CI_COMMIT_REF_NAME, it stores the branch name.

To know if you are in a branch we could do one of these two:

• Check if CI_COMMIT_REF_NAME != VERSION
• Run a job only if we are in a branch (and set the var TRAVIS_PULL_REQUEST) using only or except

Maybe there are other options, but in the documentation there is not a variable specific to know if we are in a MR

As mentioned in this Gitlab issue, there are no available variable to access merge request information.

So, I think our best guess is to use something like @ruiztulio 's idea: CI_COMMIT_REF_NAME != VERSION

[luisg123v]

I'd like to know:

• Should this be addressed from here at mqt?
• Should this be done in an existing script like travis_run_tests or travis_install_nightly, or should it be on a separate script, something like travis_init_env?

[moylop260]

We have 2 options:

1. Use gitlab-ci.yml file to translate
2. Use a MQT script to translate if there is not environment variables of travis.

[ruiztulio]

@moylop260 I think is better to use the MQT script because in this way we'll have it available in all repos instead of changing all the ci files
