Stefan Kögl created COUCHDB-1769:
------------------------------------
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.
