> Key: COUCHDB-1570
> URL: https://issues.apache.org/jira/browse/COUCHDB-1570
> Project: CouchDB
> Issue Type: Bug
> Components: Replication
> Affects Versions: 1.2
> Environment: Mac OS X 10.8.2
> Reporter: Jens Alfke
> Assignee: Randall Leeds
> Priority: Blocker
> Fix For: 1.3
>
>
> If a 'push' replication receives error responses from the remote server while
> PUTting documents, it may write a corrupt checkpoint document to the remote
> server -- its _revisions._ids property is null. Any subsequent attempt to
> push to that server will cause the replicator to abort with an error when
> reading that replication document, since it requires _revisions.ids to be an
> array.
> The only workaround for this, short of deleting the remote database entirely,
> is to (a) identify the URL of the remote checkpoint document, and (b) delete
> it from the remote server. Otherwise you will never be able to push to that
> database again.
> Here's a failed replication attempt:
> $ curl -X POST --user snej :5984/_replicate --header
> Content-Type:application/json --data
> '{"source":"demo-shopping-attachments","target":"http://localhost:4984/demo-shopping-attachments","create_target":true}'
> {"error":"doc_validation","reason":"_revisions.ids isn't a array."}
> Here's the contents of the remote checkpoint document, once I identified its
> ID:
> $ curl :4984/demo-shopping-attachments/_local/5b913befe682d7bd1fbc24b1ce31cbc5
> {"_id":"_local/5b913befe682d7bd1fbc24b1ce31cbc5","_rev":"0-1","_revisions":{"ids":null,"start":0},"history":[{"doc_write_failures":2,"docs_read":2,"docs_written":0,"end_last_seq":207,"end_time":"Sun,
