XML-RPC request to tell the supermirror a mirrored branch has been updated

[Robert Collins]

It would be great if launchpad could be notified when branches that are
not hosted have been updated. On the bzr side the bzr-dbus plugin
already receives notification of branch changes and could forward to
launchpad without slowing down commit; alternatively a new plugin could
be written or the functionality added to the built-in launchpad-plugin.
OTOH this will be somewhat more complex if its not to slow commit down.

In terms of the needed API I think just 'URL, new_tip_revision_id'
should be enough - launchpad can discard URL's it does not know of, or
duplicates - and it shouldn't even need authentication as it does not
disclose any information.

This could be tied into the addition of a 'Mirror now' button or link on a mirrored branch to get the branch puller script to update the branch at the next opportunity.

[David Allouche (ddaa)]

Tim: agreed.

Robert: why do propose giving a new_type_revision_id, instead of just requesting an update at the next opportunity?

We supply that to the bzr-dbus api; its useful to know that what you saw
is what people uploaded. I guess you could just update and ignore the
revision id.

Another trivial addition once mirrored time set to the future.

This addition is fairly simple, but we might as well wait for the revised API framework before adding it. Re-assigning to Tim for triage.

[Jonathan Lange (jml)]

I just tried to do this but found navigating the new API system a little tricky. Will talk to Francis or Leonard about it tomorrow.

[Jonathan Lange (jml)]

I've submitted a fix for this to PQM. It just exposes requestMirror(), as in our internal API.

How do I use it ?

It's part of the regular Launchpad APIs. Stay tuned for the release of launchpadlib.

Ok, cool. I've linked the spec you created; hopefully the library will
be one that the launchpad plugin in bzrlib can use. (Though it would be
nice to have C etc bindings too :P)
