At the time I write this the bugzilla "Dashboard" is showing just one port that is matched by the pre-canned query for "Ports bugs, that are ready to be taken by a committer".
That's definitely not accurate. I suppose it's because the query relies on the "patch-ready" keyword and that keyword is not on enough bugs. I wasn't able to dig up information on patch-ready, however, to determine why more ports are not labeled with it. The keyword field appears to be read-only for me.
Is there a procedure I've missed to encourage a committer to process a bug that's ready to go? Or is there just a triage / committer bandwidth shortage?
