Mike Leddy commented on COUCHDB-999:
------------------------------------
I noticed that what appears in the couch.log is somewhat difficult to
understand:
[Thu, 16 Jun 2011 14:51:54 GMT] [error] [<0.886.0>] ** Generic server <0.886.0>

The exit message is not being shown as a normal 'string' in the log.
> Detect view indexes with duplicates in them
> -------------------------------------------
>
> Key: COUCHDB-999
> URL: https://issues.apache.org/jira/browse/COUCHDB-999
> Project: CouchDB
> Issue Type: New Feature
> Components: Database Core
> Affects Versions: 0.11.2, 1.0.1
> Reporter: Adam Kocoloski
> Fix For: 1.0.2, 1.1
>
> Attachments:
> 0001-Crash-if-duplicates-are-detected-during-view-compact.patch
>
>
> In COUCHDB-968 we discovered and fixed a bug that could introduce duplicate
> documents in a database. Under certain circumstances these duplicate
> documents would introduce duplicate entries in view indexes.
> We can detect duplicates in the view group by looking for duplicate entries
> in the docid => view key btree. We can try to repair the view indexes by
> removing the extra keys from the views, or we can just report that duplicates
> exist in the view group and direct the user to rebuild that group. We might
> incorporate this code into the view compactor, or we might release it as a
> separate standalone tool.
> I think my personal preference is to include any repair functionality in the
> view compactor. A separate standalone tool that simply reports the presence
> of duplicates would also be a nice thing to have.
