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

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.
