The images were overlapping with the title of the slides. With this change I introduce a new style with a 10 px bottom padding and add it to every image which is right under a title of a slide. Change-Id: Id91bae446819b4edce5faf084c4d954d4cd8e73a Signed-off-by: csatari <gergely.csatari@nokia.com>

nondeterministic check/gate failures.
|
|
- Reviews has a list of important reviews based on blueprint and bug priority
|
|
organized by project.

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 <http://status.openstack.org/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
|
|
|
|
- Discuss your findings with your group

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

Intermittent Failures
|
|
=====================
|
|
- Caused by timing/connectivity issues in check/gate
|
|
- May receive elastic recheck message
|
|
- List of `Rechecks <http://status.openstack.org/elastic-recheck>`_
|
|
- 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
