l.c.p.w.ImportedBranchPolicy(BranchMirrorerPolicy) : class documentation

Part of lp.codehosting.puller.worker View In Hierarchy

Mirroring policy for IMPORTED branches.

In summary:

don't follow references,

assert the URLs start with the prefix we expect for imported branches.

Method	createDestinationBranch	See `BranchOpenPolicy.createDestinationBranch`.
Method	should_follow_references	See `BranchOpenerPolicy.should_follow_references`.
Method	transform_fallback_location	See `BranchOpenerPolicy.transform_fallback_location`.
Method	check_one_url	See `BranchOpenerPolicy.check_one_url`.

Inherited from BranchMirrorerPolicy:

Method getStackedOnURLForDestinationBranch Get the stacked on URL for source_branch.

def createDestinationBranch(self, source_branch, destination_url):

overrides lp.codehosting.puller.worker.BranchMirrorerPolicy.createDestinationBranch

See BranchOpenPolicy.createDestinationBranch.

Because we control the process that creates import branches, a vfs-level copy is safe and more efficient than a bzr fetch.

def should_follow_references(self):

See BranchOpenerPolicy.should_follow_references.

We do not traverse references for IMPORTED branches because the code-import system should never produce branch references.

def transform_fallback_location(self, branch, url):

See BranchOpenerPolicy.transform_fallback_location.

Import branches should not be stacked, ever.

def check_one_url(self, url):

See BranchOpenerPolicy.check_one_url.

If the URL we are mirroring from does not start how we expect the pull URLs of import branches to start, something has gone badly wrong, so we raise AssertionError if that's happened.
