James E. Blair 8b1dc3fb22 Add dynamic reconfiguration ... If a change alters .zuul.yaml in a repo that is permitted to use in-repo configuration, create a shadow configuration layout specifically for that and any following changes with the new configuration in place. Such configuration changes extend only to altering jobs and job trees. More substantial changes such as altering pipelines will be ignored. This only applies to "project" repos (ie, the repositories under test which may incidentally have .zuul.yaml files) rather than "config" repos (repositories specifically designed to hold Zuul configuration in zuul.yaml files). This is to avoid the situation where a user might propose a change to a config repository (and Zuul would therefore run) that would perform actions that the gatekeepers of that repository would not normally permit. This change also corrects an issue with job inheritance in that the Job instances attached to the project pipeline job trees (ie, those that represent the job as invoked in the specific pipeline configuration for a project) were inheriting attributes at configuration time rather than when job trees are frozen when a change is enqueued. This could mean that they would inherit attributes from the wrong variant of a job. Change-Id: If3cd47094e6c6914abf0ffaeca45997c132b8e32		2016-07-18 09:58:19 -07:00
