4.12.2.1 Property

You can use build properties in most step paramaters. Please file bugs for any parameters which do not accept properties. The simplest form is to wrap the property name with Property, passing an optional default argument.

     from buildbot.steps.trigger import Trigger
     form buildbot.process.properties import Property
     
     f.addStep(Trigger(waitForFinish=False, schedulerNames=['build-dependents'], alwaysUseLatest=True,
     			set_properties={'coq_revision': Property("got_revision")}))

You can specify a default value by passing a default argument to Property. This is normally used when the property doesn't exist, or when the value is something Python regards as "false". The defaultWhenFalse argument can be used to force buildbot to use the default argument only if the parameter is not set.
