Adam Kocoloski updated COUCHDB-174:
-----------------------------------
Attachment: couch_rep.diff
> Docs with lots of revisions break replication
> ---------------------------------------------
>
> Key: COUCHDB-174
> URL: https://issues.apache.org/jira/browse/COUCHDB-174
> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Reporter: Adam Kocoloski
> Attachments: couch_rep.diff
>
>
> When replicating from a remote source CouchDB uses the open_revs query string
> parameter in a document request and supplies a list of revisions that are
> present on the source but not on the target. If this list is very large the
> resulting URL might exceed 8 KB, in which case MochiWeb/gen_tcp will not
> serve the request.
> I'm sure there are a number of ways to work around this limitation. I'm
> attaching a patch that checks if the URL formed from the list of revs to open
> will be larger than 8 KB, and if so chunks the list and makes multiple
> smaller requests. Best,
> Adam
