Document update conflict. and attachments

[Martin Hilbig]

hi,

is this a known bug or even my fault?
create db:

curl -X PUT http://localhost:5984/fail
{"ok":true}

create doc:

curl -vX PUT http://localhost:5984/fail/doc -d '{}'
{"ok":true,"id":"doc","rev":"1-967a00dff5e02add41819138abb3284d"}

put attachment with nearly correct format ?rev=x-y

curl -vX PUT http://localhost:5984/fail/doc/att?rev=12-12345 -d '{}'
> PUT /fail/doc/att?rev=12-12345 HTTP/1.1
> User-Agent: curl/7.21.3 (x86_64-unknown-linux-gnu) libcurl/7.21.3

{"error":"{not_found,missing}","reason":"{12,<<\"12345\">>}"}

shouldn't look this like:

curl -X PUT 
http://localhost:5984/fail/doc/att?rev=1-967a00dff5e02add41819138abb3284d -d 
'{}'
{"ok":true,"id":"doc","rev":"2-25fb7eb27842ed11617f4e8656600c54"}

curl -vX PUT 
http://localhost:5984/fail/doc/att?rev=1-967a00dff5e02add41819138abb3284d -d 
'{}'
> PUT /fail/doc/att?rev=1-967a00dff5e02add41819138abb3284d HTTP/1.1

{"error":"conflict","reason":"Document update conflict."}

to sum it up: couchdb only sends a correct 'document update conflict' on 
attachments, when you give a rev already in the documents history.

have fun
