Replication target with only DB name replicates to node-local port

[segevfiner]

Description

When you create a replication that specifies a target using only a database name, CouchDB will replicate to the node local port which is unexpected and not really useful. Since AFAIK user_ctx only works when you specify the source/target as only a DB name that also neuters that feature and basically local DB references in replications in general.

Steps to Reproduce

Create a replication like this:

{
  "_id": "foo",
  "source": "http://some-other-db:5984/foo",
  "target": "foo",
  "continuous": true,
  "user_ctx": {"name": "admin","roles": ["_admin"]}, "owner": "admin"}
}

Expected Behaviour

The target database is replicated on the standard clustered port (5984). But it is replicated to the node local (5986) port instead.

This has been resolved in CouchDB 3.0.0. We do not expect another 2.x release at this point. Thanks for this report!
