> Key: COUCHDB-1518
> URL: https://issues.apache.org/jira/browse/COUCHDB-1518
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Affects Versions: 1.1.1, 1.2
> Environment: Debian Linux 6.0.5 / CouchDB 1.1.1 / Erlang R14B03
> Ubuntu Linux 12.04 / CouchDB 1.2.0 / Erlang R15B01
> Reporter: Colin Coghill

> When COPYing a document with attachments, the _rev of the new document is set to 1-something, but the revpos on the attachments is left as is, meaning they're generally higher than the _rev of the new document.
> I believe this is incorrect, and will cause problems later when updating/replicating the document. (I believe I'm seeing specific problems and am working on a test case, but am not sure they're particularly necessary if this behaviour is incorrect)
> It's quite possible I've misunderstood how attachment revpos works and that this behaviour is ok.
> Specific naming IDs, attachments, etc, don't seem to matter, substitute your own.
> Untested on earlier versions of CouchDB.
> curl -X PUT http://127.0.0.1:5984/testdb/document1 -d '{"name": "cat pictures"}'
> curl -X GET http://127.0.0.1:5984/testdb/document1
> # Note down REV and put it in the attachment upload:
> curl -X PUT http://127.0.0.1:5984/testdb/document1/cat1.jpg?rev=REV --data-binary @cat1.jpg -H 'Content-Type: image/jpeg'
> # Copy the document
> curl -X COPY http://127.0.0.1:5984/testdb/document1 -H "Destination: document2"
> curl -X GET http://127.0.0.1:5984/testdb/document2
> # Note: revision is 1-something
> # revpos on attachment is 2-something
