Class BuildMaster

Overrides: twisted.application.service.MultiService.__init__

Overrides: twisted.application.service.Service.startService

Internal function to load a specific configuration file. Any errors in the file will be signalled by raising an exception.

If check_synchronously_only=True, I will return (with None) synchronously, after checking the config file for sanity, or raise an exception. I may also emit some DeprecationWarnings.

If check_synchronously_only=False, I will return a Deferred that fires (with None) when the configuration changes have been completed. This may involve a round-trip to each buildslave that was involved.

Special descriptor for class __provides__

The descriptor caches the implementedBy info, so that
we can get declarations for objects without instance-specific
interfaces a bit quicker.

For example:

  >>> from zope.interface import Interface
  >>> class IFooFactory(Interface):
  ...     pass
  >>> class IFoo(Interface):
  ...     pass
  >>> class C(object):
  ...     implements(IFoo)
  ...     classProvides(IFooFactory)
  >>> [i.getName() for i in C.__provides__]
  ['IFooFactory']

  >>> [i.getName() for i in C().__provides__]
  ['IFoo']
