> Good news! [~stack], [~Apache9], I may find the root cause of mysterious
> ‘Corrupted procedure’ or some procedures disappeared after master
> restarts(happens during ITBLL).
> This is because during master restarts, we load procedures from the log, and
> builds the 'holdingCleanupTracker' according each log's tracker. We may mark
> a procedure in the oldest log as deleted if one log doesn't contain the
> procedure. This is Inappropriate since one log will not contain info of the
> log if this procedure was not updated during the time. We can only delete the
> procedure only if it is not in the global tracker, which have the whole
> picture.
> {code}
> trackerNode = tracker.lookupClosestNode(trackerNode, procId);
> if (trackerNode == null || !trackerNode.contains(procId) ||
> trackerNode.isModified(procId)) {
> // the procedure was removed or modified
> node.delete(procId);
> }
> {code}
> A test case(testProcedureShouldNotCleanOnLoad) shows cleanly how the
> corruption happened in the patch.
