GitLab

As per our roadmap session made during Summit 2020.

There are many ideas in the air, let's use this issue to gather them and start with something.

Potential candidates

Public stuff, no credentials required

• #16712 (closed)
• check_PO_master (Jenkins job definition, check_PO builder), that runs lint_po, which itself uses i18nspector:
  • It would be nice if translators could see the status of the CI check.
  • This would allow us to run whichever version of i18nspector we want, e.g. to benefit from new checks we've requested after translation mistakes caused bugs in Tails.
• Checking PO files on any branch, currently done in features/po.feature: same as check_PO_master, it would be nice to be able to choose the version of i18nspector we're using
• Check PO files with msgfmt. We'll see if it catches errors that i18nspector misses: if not, we should consider dropping the msgfmt check.
• WhisperBack's unit tests (added to our Cucumber test suite via tails#16936 (closed), but arguably this would be better suited for GitLab CI)
• The subset of tails#15330 that can be done without booting Tails
• #17775
• tails#17940
• Linters:
  • Rubocop (tails#17646 (closed))
  • ShellCheck (tails!190)

Sensitive stuff

• #17364
• Run gitlabracadabra from tails/gitlab-config, e.g. in dry-run mode and then a step to manually confirm and run the deploy.
• Issue triaging with gitlab-triage (currently run manually by intrigeri)
• Weblate integration scripts (could improve reporting, collaboration and overall design)

Current conclusions

• We don't need the registry as long as we don't need store any built container images in it. (We have no registry at the moment.)
• For the simple non-ISO jobs we consider here, the Docker runner should work.
• In production we'll want to trust sufficiently the runners: humans make decisions based on CI output. Possibly during initial dev work we can use less trusted runners, and tell developers they shall not trust the results (yet).

Next steps

• Let developers try the CI out and gather feedback.
• Sysadmins: make the GitLab CI runners into production.

Clean up once GitLab CI is in production

• tails#17992
• #17776
