  1. About Me • Nazir Bilal Yavuz • Open Source Postgres

    Team @Microsoft • Working on Postgres ~2 years • Mainly build and CI stuff
  2. What is CI • Stands for Continuous Integration • Automating

    the integration of new code changes ◦ Build ◦ Test • Main benefits ◦ Find bugs quicker ◦ Fasten the development cycle
  3. Why we need CI on Postgres • Patch is sent

    but… ◦ Your changes are not working on… • Testing changes on various platforms • Developer productivity ◦ Find bugs fast ◦ Shorter review period
  4. New CI system • Uses Cirrus CI (https://cirrus-ci.org/) ◦ Continuous

    integration and deployment platform that enables developers to automate their software development workflows • Steps to run CI: ◦ Enable CI ◦ Push changes ◦ See results ◦ PG16
  5. 2 - Add Cirrus CI application to your GitHub account

    • https://github.com/marketplace/cirrus-ci
  6. 3 - Cirrus CI should access to forked PG repository

    • GitHub -> Settings -> Applications -> Cirrus CI
  7. CI tips • Cirrus terminal • Gathering logs • on_failure

    instruction ◦ instruction ▪ I will refer it as a key on yaml file
  8. Cirrus terminal • When Postgres is working on your local

    but you see failures on CI • No need to run CI again
  9. Gathering logs • *_artifact instruction • Analyze logs offline •

    By default log, diff, regress logs • Need to gather other files (e.g. docs)
  10. on_failure instruction • Only when we come across a failure

    • Avoid unnecessary logging • Faster CI runs for successful build
  11. In Summary • Enable new CI on GitHub • Push

    changes to trigger CI run ◦ CI reads .cirrus.yml file • See the results • If debugging is needed ◦ Use Cirrus terminal ◦ Gather & investigate logs ◦ Use on_failure if needed
