Hi,

I should better ask before I open a ticket. I think it is a kind of =
replication bug:

Steps to reproduce on CouchDB 1.01:

1. Create a database 'test' on a CouchDB server. Note must be somewhere =
on remote location not local!!!
2. Put document 'doc' to the remote db.
3. Create local database 'test'
4. Pull replication from the local server:    =20

curl -X POST -d '{"source":"test","target": =
"'http://remote-location:5984/test'" }'  =
http://localhost:5984/_replicate=20

5. Attach a text file to the replicated document on the local db
6. Push replication from the local server:

curl -X POST -d '{"source": =
"'http://remote-location:5984/test'","target": "test" }'  =
http://localhost:5984/_replicate=20

7. Try to DELETE the document on the remote database location.

There are two documents with the same name but different revision =
numbers. You can see this just if you try to delete the document.=20
If you repeat the procedure for another attachment you have to delete =
two documents before you delete the whole document record.
The revision number is incremented and the replication makes another =
copy of the document with the same name  but different revision number =
on the remote database. This happens only with documents containing =
attachments and only by replication between different databases on =
different servers.

I was able to reproduce this with CouchdDB (1.0.1) on MacOSX, WinXP and =
Win7 changing the rules of local and remote servers.

Cheers
Nikolai
