             Summary: Replicator manager crashes in terminate/2 if initial change feed spawned for _replicate hasn't finished
                 Key: COUCHDB-3082
                 URL: https://issues.apache.org/jira/browse/COUCHDB-3082
             Project: CouchDB
          Issue Type: Bug
            Reporter: Nick Vatamaniuc




During init we spawn a change feed for the _replicator db and assign rep_start_pids = [Pid]. However the shape of rep_start_pids should be {Tag, Pid}. In terminate/2 we clean up by doing:

lists:foreach(
fun({_Tag, Pid}) ->
...
[{scanner, ScanPid} | StartPids]),

 

Which ends up crashing with a function clause because we expect foreach function to get a tuple of 2 items.
