James Howe commented on COUCHDB-1496:
-------------------------------------
When the document is deleted, all other properties are removed, so the _deleted
revisions are not passing "if (doc.type)".
You need to either not delete documents with DELETE, or add "if (doc._deleted)
{ return true; }" to the filter.
> Incomplete Replication on Several Circumstances
> -----------------------------------------------
>
> Key: COUCHDB-1496
> URL: https://issues.apache.org/jira/browse/COUCHDB-1496
> Project: CouchDB
> Issue Type: Bug
> Affects Versions: 1.2
> Environment: iriscouch
> Reporter: Maya Alipin
> Priority: Minor
>
> I have found that on several circumstances, CouchDB's continous filtered
> replication doesn't do what I expect.
> 1. deleted documents in source database ends up not deleted in destination
> database
> 2. I notice on continuous replication, the replication status will remain
> incomplete until check-pointed sequence equals source sequence. On continuous
> filtered replication, an update may not pass the filter and cause the
> replication to become incomplete.
> I found the replication remains incomplete even if there is an update that
> pass the filter. I need to restart the replication to get the update
> replicated to the destination database.
> Test Scenario:
> 1. Trigger a filtered continuous replication from database X to database Y on
> _replicator database. Replication progress is 100%
> 2. Add new document(A1) on database X.
> 3. Document A1 pass the replication filter, thus A1 is replicated to database
> Y. Replication progress is 100%
> 4. Delete document A1 on database X. Replication progress become 99%,
> document A1 still exists on database Y.
> 6. Restart the filtered continuous replication from database X to database Y
> by deleting document on _replicator database and create it again
> 7. Replication progress stops at 99%.
> 8. Add new document(A2) on database X.
> 9. Document A2 pass the replication filter, thus A2 is replicated to database
> Y. Replication progress become 100%
> 10. Delete document A2 on database X. Replication progress become 99%,
> document A2 still exists on database Y.
