Pull replication by doc-IDs, from a CouchDB version < 1.1.0, no longer works
when sent from a CouchDB 1.1.0+ server
-------------------------------------------------------------------------------------------------------------------
Key: COUCHDB-1028
URL: https://issues.apache.org/jira/browse/COUCHDB-1028
Project: CouchDB
Issue Type: Bug
Components: Replication
Affects Versions: 1.1
Reporter: Filipe Manana
Assignee: Filipe Manana
Attachments: COUCHDB-1028.patch
After Benoît added the built-in _changes filter _doc_ids to trunk (and now in
1.1.x as well), I updated the replicator to use it for the replication by
doc-IDs. The advantages of this are:
1) Elimination of very specific, and harder to maintain, code from several
replicator modules;
2) Allow for continuous by doc-IDs replication (this was not possible before
because a replication by doc-IDs didn't use the _changes stream at all)
The change was done in the following commit:
https://github.com/apache/couchdb/commit/5afece2131f4ef4000d768b671bddbbf714303d9
It happens that with the branch 1.1.x (and trunk as well), it's no longer
possible to pull replicate by doc-IDs from previous CouchDB versions (since
they don't have that new built-in filter).
The following patch fixes the issue by changing only 1 module of the
replicator. If no objections, I'll commit it later.
