Message #25506
[Merge] ~cjwatson/launchpad:code-import-worker-librarian into launchpad:master
Colin Watson has proposed merging ~cjwatson/launchpad:code-import-worker-librarian into launchpad:master.
Commit message:
Send code import log file data over XML-RPC
Requested reviews:
Launchpad code reviewers (launchpad-reviewers)
For more details, see:
https://code.launchpad.net/~cjwatson/launchpad/+git/launchpad/+merge/392369
This will make it easier to split out the code import worker from the main Launchpad codebase, as it will no longer need the remote librarian upload client which currently expects to have direct Launchpad database access.
--
Your team Launchpad code reviewers is requested to review the proposed merge of ~cjwatson/launchpad:code-import-worker-librarian into launchpad:master.
