Since 2.0.0:
|
|
|
|
* The push_change_refs option which specified that Zuul refs should be
|
|
pushed to Gerrit has been removed.
|
|
|
|
* Git merge operations are now performed in a separate process. Run
|
|
at least one instance of the ``zuul-merger`` program which is now
|
|
included. Any number of Zuul-Mergers may be run in order to
|
|
distribute the work of speculatively merging changes into git and
|
|
serving the results to test workers. This system is designed to
|
|
scale out to many servers, but one instance may be co-located with
|
|
the Zuul server in smaller deployments. Several configuration
|
|
options have moved from the ``zuul`` section to ``merger``.
|
|
|
|
Since 1.3.0:
|
|
|
|
* The Jenkins launcher is replaced with Gearman launcher. An internal
|
|
Gearman server is provided, and there is a Gearman plugin for
|
|
Jenkins, so migration to the new system should be fairly
|
|
straightforward. See the Launchers section of the documentation for
|
|
details.
|
|
|
|
* The custom parameter function signature has changed. It now takes a
|
|
QueueItem as the first argument, rather than the Change. The
|
|
QueueItem has the full context for why the change is being run
|
|
(including the pipeline, items ahead and behind, etc.). The Change
|
|
is still available via the "change" attribute on the QueueItem. The
|
|
second argument is now the Job that is about to be run, and the
|
|
parameter dictionary is shifted to the third position.
|
|
|
|
* The ZUUL_SHORT_* parameters have been removed (the same
|
|
functionality may be achieved with a custom parameter function that
|
|
matches all jobs).
|
|
|
|
* Multiple triggers are now supported (currently Gerrit and a simple
|
|
Timer trigger are supported). Your layout.yaml file will need to
|
|
change to add the key "gerrit:" inside of the "triggers:" list to
|
|
specify a Gerrit trigger (and facilitate adding other kinds of
|
|
triggers later). See the sample layout.yaml and Zuul section of the
|
|
documentation.
|
|
|
|
* Some statsd keys have changed in a backwards incompatible way:
|
|
* The counters and timers of the form zuul.job.{name} is now split
|
|
into several keys of the form:
|
|
zuul.pipeline.{pipeline-name}.job.{job-name}.{result}
|
|
* Job names in statsd keys now have the '_' character substituted
|
|
for the '.' character.
|
|
|
|
* The layout.yaml structure has changed to introduce configurable
|
|
reporters. This requires restructuring the start/success/failure
|
|
actions to include a dictionary of reporters and their parameters.
|
|
See reporters in the docs and layout.yaml-sample.
|
|
|
|
* The zuul_url configuration option is required in zuul.conf. It
|
|
specifies the URL of the git repositories that should be used by
|
|
workers when fetching Zuul refs and is passed to the workers as the
|
|
ZUUL_URL parameter. It should probably be set to
|
|
"http://zuul-host-name/p/".
