# HG changeset patch -- Bitbucket.org # Project galaxy-dist # URL http://bitbucket.org/galaxy/galaxy-dist/overview # User Dannon Baker dannon.baker@emory.edu # Date 1277490892 14400 # Node ID c02ecbcc8dab54e7007b35db5a05e31211d77b01 # Parent df5010a5df581674896beec9b35ca50bf477f380 New Feature: Administrative Job Lock. Admins can now lock (and unlock) all job dispatching. New jobs will remain in the job queue in the 'waiting' state until the lock is removed. Existing dispatched jobs are unaffected, and jobs can still be submitted, but they will not dispatch.
