Subject [jira] [Created] (COUCHDB-1769) Duplicates in View indexes

------------------------------------

             Summary: Duplicates in View indexes
                 Key: COUCHDB-1769
                 URL: https://issues.apache.org/jira/browse/COUCHDB-1769
             Project: CouchDB
          Issue Type: Bug
          Components: JavaScript View Server
            Reporter: Stefan Kögl


The compaction of a view (created with CouchDB 1.3) failed due to view_duplicate_id. The database
to which the view belongs was created with 1.2.x but compacted (with the 0-byte-compact-file
trick) with 1.3.

A full log of the failed compaction can be found at

I experienced the same behaviour already with previous versions but assumed it might be gone
with 1.3, but this seems not to be the case. 

When such duplicates happen (and appear during compaction), they seem to be at the beginning
of the view index. The view in question has the following _info:

{noformat}
{"name":"listeners","view_index":{"signature":"854a8065b438b3e53fcdbbe0a79a8e80","language":"javascript","disk_size":2679632207,"data_size":1026614011,"update_seq":58353111,"purge_seq":0,"updater_running":false,"compact_running":false,"waiting_commit":false,"waiting_clients":0}}
{noformat}

Compaction stopped with a 39M large .compact.view file.

Also the problem seems to happen only one some machines.
