Zuul
Zuul Pipelines
- Check
- Run against all newly updated patch sets
- Jenkins votes +1/-1 depending on test results
- Gate
- Only run after a patch is approved by a core reviewer
- More extensive testing than check pipeline
- 'Gates' code entering the stable or master branches
- Post
- Jobs run against a patch after it merges
Exercise
- Look at the Zuul status page
- Find the information that can be retrieved for each patch in a pipeline
- What happens if you click on a patch under test
- How many gate and check jobs are running
- Pick your favorite project and report how many jobs it has running in IRC
- What is the significance of the dots, lines and colors
- Find the information that can be retrieved for each patch in a pipeline
- Discuss your findings with your group
Jenkins Failures
Analysing Jenkins Failures
- Logs may be accessed by clicking on the test's name
- Directs the user to saved log output
- Uses the browser to view the logs
- Voting and non-voting jobs
- Voting job failures cause a -1 vote from Jenkins on the patch
- Non-voting jobs do not cause a -1 vote from Jenkins upon failure
- Non-voting jobs are new jobs that are being tested and may not yet be ready to vote
Log Output
Intermittent Failures
- Caused by timing/connectivity issues in check/gate
- May receive elastic recheck message
- List of Rechecks
- To trigger a re-run of check or gate add a comment to the patch in the form of 'recheck bug XXXXX'
Exercise
- Find how rechecks are categorized
- Discuss with your table how you would determine you encountered one of these bugs
