API call for finding branches that contain a revid

[Jelmer Vernooij]

It would be useful if there was some way to find *any* branch on launchpad that contained a particular revision id. This would be useful for example when writing a plugin that short-circuits revision imports from foreign branches.

e.g. if I was doing a "bzr clone of git://git.kernel.org/pub/linux-2.6.git" the plugin could recognize that some bzr revids it would generate were already present in e.g. lp:~vcs-imports/linux/2.6 and fetch them from there instead (as that would be significantly faster than importing from git).

Seems sensible enough.

This sounds like the best option for the Q/A scripting machinery to tie commits to bugs right now. I understand that the branch revision table is enormous though... is there any risk of performance limitations scuppering this option?

Once this is implemented, we can track Q/A through bugs: you land a branch to fix bug X, and bug X automatically gets tagged as needing Q/A. The tags make it easy to view Q/A workload for persons, teams, categories, etc.

In the Translations team we've been working this way for a few months and it works very nicely—except this bug is the missing link for the scripts to figure out the right bug based on a commit.

We already automatically link branches to bugs based on a commit. Why
do you need something else?

The script needs to find the right branch, given a revision. The connection all the way to the bug is currently made through textual tags in merge messages.
