Undocumented
def _real_stream(self, repo, search):
Get a stream for search from repo.

This never called RemoteStreamSource.get_stream, and is a heler for RemoteStreamSource._get_stream to allow getting a stream reliably whether fallback back because of old servers or trying to stream from a non-RemoteRepository (which the stacked support code will do).

def _get_stream(self, repo, search):
Core worker to get a stream from repo for search.

This is used by both get_stream and the stacking support logic. It deliberately gets a stream for repo which does not need to be self.from_repository. In the event that repo is not Remote, or cannot do a smart stream, a fallback is made to the generic repository._get_stream() interface, via self._real_stream.

In the event of stacking, streams from _get_stream will not contain all the data for search - this is normal (see get_stream).

ParametersrepoA repository.
searchA search.
def missing_parents_chain(self, search, sources):
Chain multiple streams together to handle stacking.
ParameterssearchThe overall search to satisfy with streams.
sourcesA list of Repository objects to query.
def missing_parents_rev_handler(self, substream):
Undocumented
