4.7.1 Configuring Schedulers

c['schedulers'] is a list of Scheduler instances, each of which causes builds to be started on a particular set of Builders. The two basic Scheduler classes you are likely to start with are Scheduler and Periodic, but you can write a customized subclass to implement more complicated build scheduling.

Scheduler arguments should always be specified by name (as keyword arguments), to allow for future expansion:

     sched = Scheduler(name="quick", builderNames=['lin', 'win'])

All schedulers have several arguments in common:

Each Scheduler must have a unique name. This is used in status displays, and is also available in the build property scheduler.
This is the set of builders which this scheduler should trigger, specified as a list of names (strings).
This is a dictionary specifying properties that will be transmitted to all builds started by this scheduler. The owner property may be of particular interest, as its contents (as a list) will be added to the list of "interested users" (see Doing Things With Users) for each triggered build. For example:
          sched = Scheduler(...,
              properties = { 'owner' : [ '', '' ] })

The remaining subsections represent a catalog of the available Scheduler types. All these Schedulers are defined in modules under buildbot.schedulers, and the docstrings there are the best source of documentation on the arguments taken by each one.
