Event Timeline

olasd added a subscriber: olasd.

There's nothing in the spec that would prevent having to follow a chain of aliases, but I guess a single step resolution is good enough for now.

I suggest that at some point the "branch alias resolution" moves to the swh.storage.algorithms.snapshot module as a generic tool: I think it would make sense to have a "get the target directory for this branch on this snapshot" function, which would return the list of objects traversed up to the directory: branch aliases, releases, revisions.

This will also prepare us for the resolution of T1258.

This revision is now accepted and ready to land.Oct 23 2019, 12:09 PM
