> Key: COUCHDB-2536
> URL: https://issues.apache.org/jira/browse/COUCHDB-2536
> Project: CouchDB
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: Database Core
> Affects Versions: 1.6.1
> Environment: Windows 7 (64bit)
> Reporter: Dennis

> Hi,
> We have two database A and B.. Database A contains documents having the same
> ids as documents in database B. Our goal was to replace the documents of
> database B with the documents of database A, iff the document have the same
> id. Therefore, we replicated the content of database A to database B. At
> first it seems to work perfectly but then we discovered the following issues:
> If we delete a document in database B which was replaced by a document of
> database A, then the document which was replaced reappeared.
> Minimal setup to reproduce this behaviour:
> Database A contains a document {"_id": "mykey", "content" : "foo"}
> Database B contains a document {"_id": "mykey", "content" : "bar"}
> Replicate database A to Database B (using the CouchDB replicator).
> Database B now contains a document {"_id": "mykey", "content" : "foo"} as
> expected. This document has now previous versions.
> If document with the key "mykey" is deleted in database B, the document
> {"_id": "mykey", "content" : "bar"} reappears in the database.
> Why does the replaced document reappear? Is this the intended behaviour of
> CouchDB or a bug?
> We expected to get a conflict during replication or that maybe the existing
> document in database B is set as the previous version of the document, by
> which it was replaced. But the current behaviour was unexpected.
> We are using CouchDB 1.6.1 on Windows 7 (64bit).
> Best regards
> Dennis
