Subject [jira] [Created] (COUCHDB-1384) File descriptor leak if view compaction is cancelled
Date Thu, 19 Jan 2012 13:03:39 GMT
File descriptor leak if view compaction is cancelled
----------------------------------------------------

                 Key: COUCHDB-1384
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1384
             Project: CouchDB
          Issue Type: Bug
    Affects Versions: 1.2
            Reporter: Filipe Manana
            Priority: Critical
             Fix For: 1.2
         Attachments: 0001-Close-view-compaction-file-when-compaction-is-cancel.patch

If a view compaction is canceled, the compact file's fd remains open as long as the view group
is alive.
This is because the couch_file the compactor uses is spawn_linked by the view group and not
linked to the compactor process, therefore when the compactor is shutdown the corresponding
couch_file is not shutdown. The view group doesn't keep track of the compact file's couch_file,
so it can't explicitly shutdown it either.

This affects only the 1.2.x branch and is addressed by simply linking the file process to
the compactor process. Patch attached.
