------------------------------------
Summary: 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.
