A little while ago I blogged about a new process to request a new branch on an existing package.
The code to support this change is now under review but I thought I should document the workflow a little bit, so here is how I tried to design things:
Ideally, when the branch is approved and created in pkgdb by the admin, pkgdb will send a message on fedmsg, message that will be seen by a fedmsg-consummer that will automatically update the git repos within, say 2 minutes. That last part if almost ready and hopefully will be running soon.
