Doc missing from view

[Brian Candler <B....@pobox.com>]

Posted to user@ because I'm almost certainly being daft, but I just can't
see what I've done wrong.

I've used CouchRest to create a test document and view. But although the
document is there, and as far as I can see it matches the criteria in the
design doc to be emitted, the view is empty.

This is with CouchDB r755146 compiled a couple of days ago.

After going through my session transcripts I'm now able to replicate this
reliably, and it looks to me very much like a couchdb problem.

I replicated it first using Ruby/CouchRest, and then as a pure shell script.
Both are attached.

When I run this, I see the output of the "all" and "by_foo" views are empty.
However if I comment out one of the document updates, so that the second one
doesn't fail with a conflict, then the view works just fine.

So somehow, a document update which was rejected due to an incorrect _rev
has caused the entire document to become invisible to the view.

Brian.
