New Features
============
* Gerrit and GitHub repositories will now automatically use the default
branch as specified in their respective systems as the project’s
default branch. This may still be overridden in zuul using the
project.default-branch setting.
* A new job configuration option, job.failure-output, has been added to
allow users to specify regular expressions which, when seen in the
streaming job output, will trigger the early failure detection in Zuul
so that dependent pipeline gate resets may begin before the completion
of a failed job.
* Two new settings are available to protect Zuul from resource
exhaustion from processing too many dependencies among changes. The
Gerrit driver supports setting <gerrit connection>.max_dependencies to
limit internal dependency processing during event processing, and a
new tenant setting of tenant.max-dependencies is available to limit
tenant processing while enqueing changes in pipelines.
* Additional pipeline stats for individual project queues are available
at zuul.tenant.<tenant>.pipeline.<pipeline>.queue.
* Configuration options which accept regular expressions have been
updated to accept a new syntax which allows specifying that the
regular expression should be treated as a negative match.
* An upper limit on the dependent pipeline actionable window can now be
specified using the pipeline.window-ceiling setting. The default of no
upper limit remains.
Upgrade Notes
=============
* If using the GitHub driver in app mode, you should consider also
generating and adding an api_token. The option is not strictly
required but will increase rate limits and add functionality for
projects the app is not installed in.
Deprecation Notes
=================
* Regular expressions using Python syntax are deprecated in favor of RE2
syntax instead, for additional speed and safety. Negative lookahead
assertions may be replaced using the negate keyword. See Regular
Expressions for more information.
If Zuul detects a regular expression using Python syntax that is not
supported by RE2, it will register a configuration syntax
warning. These may be viewed on the configuration errors page in the
web interface.
A future version of Zuul will remove Python regex support completely
and these warnings will become errors.
