Subject [jira] Created: (COUCHDB-188) _bulk_docs fails when deleting and adding a doc with the same id

_bulk_docs fails when deleting and adding a doc with the same id

                 Key: COUCHDB-188
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
    Affects Versions: 0.9
         Environment: CouchDB revision 730414.
            Reporter: Matt Goodall

CouchDB returns a "412 Precondition Failed" when the list of changes sent to _bulk_docs deletes
a document and later creates a document with the same id as the deleted document:

    {"docs": [
        {"_id": "docid", "_rev": "<rev>", "_deleted": true},
        {"_id": "docid"}

Once fixed, the response JSON document  will return the same docid twice in the list but it's
presumably ordered consistently with the request data so any client should be able to understand
the response.

Demonstrating the problem using curl is easy enough:

$ curl -X PUT http://localhost:5984/test

$ curl -X PUT -d "{}" http://localhost:5984/test/docid

$ curl -X POST -d '{"docs": [{"_id": "docid", "_rev": "4140747751", "_deleted": true}, {"_id":
"docid"}]}' http://localhost:5984/test/_bulk_docs
{"error":"conflict","reason":"Document update conflict."}

Note: this is likely related to COUCHDB-172.
