<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Bug 286854 seems to be due to an old, no longer needed, rogue workaround.
This patch removes the workaround.
The filewatch service calls moveFileMetadata ( oldPath, newPath).
This sticks the metadata move into a queue, like so:
if ( !m_updateQueue.contains( req ) && !m_recentlyFinishedRequests.contains( req ) )
m_updateQueue.enqueue( req );
If you move oldPath to newPath twice in fairly quick succession, the first move will
still be in the m_recentlyFinishedRequests, and the metadata move will not be queued.
git blame tells me that trueg added this check with commit 840dbb6005ead in 2009.
He explained why in this comment:
// we use several systems to watch for file operations.
// Thus, we can get the same request more than once. We then
// need a way to determine if we have already handled it.
// (otherwise we would remove the previously moved data.)
// The only way to do that is to keep a list of all requests
// that have been handled in the last N seconds.
So far as I know, inotify cannot deliver the same event twice, and so this is no longer true.
So we can fix the bug by just deleting all code related to the recentlyFinishedRequests list.
