[Buildbot-devel] triggering ForceScheduler build via email?

[Stephen Davis]

Close but not quite.

I added the scheduler like so:

def IsJingleChange( change ):
	""" Determine if a change is a forced Jingle Upload build."""
	isImportant = False
	props = change.properties

	print "jingle change: ", change.comments, props		<-- never shows up in the master's log

	if props is not None:
		if props['is_jingle_upload'] is not None:
			isImportant = True

	return isImportant

# email-triggered jingle upload build
schedulers.append( SingleBranchScheduler( name="jingle_upload", branch=None, treeStableTimer=0,
					builderNames=[MacJingleUploadBuilderName, WinJingleUploadBuilderName],
					fileIsImportant=IsJingleChange ) )

I created the change like so (shortened):

	... parse email ...

	props = { 'is_jingle_upload' : True, 'is_trunk' : is_trunk }

	return ( 'svn', dict( author=name, comments="Jingle Upload", branch=tag, properties=props ) )

In the master log, one of these custom changes creates a log entry like:

2014-03-20 22:53:02-0700 [-] added change Change(revision=None, who=u'Stephen Davis', branch=u'tags/JingleTest1', comments=u'Jingle Upload', when=1395381182, category=None, project=u'', repository=u'', codebase=u'') to database

but nothing happens.  A regular change looks like this:

2014-03-20 18:44:49-0700 [-] added change Change(revision=u'168033', who=u'stephend', branch=None, comments=u"Add doxygen class block for ITView.  Hopefully this will help Xcode's code documentation parser which seems to be missing some stuff.\n", when=1395366289, category=None, project=u'', repository=u'', codebase=u'') to database
2014-03-20 18:44:49-0700 [-] added buildset 932 to database		<-- this missing seems to be the reason no build happens

The "IsJingleChange" validator never gets called.  Is there any way to turn on some debug logging in the master to figure out why it ate the Change?  Do Changes require a "revision" property?

thanks again,
stephen

I'd like to automate but it's not a source-change-triggered event.  Is it possible to trigger the ForceScheduler's build via a Change dict vended by my MaildirSource?  I've been looking at the various Change object parameters (files, revlink, author, revision, etc.) but I don't see anything that would let me explicitly trigger the scheduler that I want.
