Say I don't know that <hash> and it isn't in my log; it looks like it's pretty consistent - what's that a hash of?  can I recompute it programmatically, since there's not exactly a way to list _local docs?

Jim, the replication checkpoint document is named in the way:
/dbname/_local/<hash>. You should be able to see this document being
written to in the logs and the <hash> portion is also the value you
get back when POST'ing to _replicate (and the one shown in
_active_tasks). Delete the document in the usual fashion and
replication will do over from the start.

Trying to test a validate_doc_update function for use in replication.

Is there a way to reset or delete the replication history so I don't have to continuously recreate my target db?

There's no such thing as a replication history, only replicated
documents. So you have a few choices;

Recreate your db if you're starting from scratch this is as simple as
an additional line in your test script, curl -X DELETE $DB ; curl -X

If you're not starting from scratch, then you can simply copy the
fresh db somewhere as a backup, and re-copy it back with, say, rsync,

You may find it easier to start a js interpreter up and work through
the validation function directly, using the process outlined in
obviously you'll need to get a sample userCtx as well. I would think
you can use the same logging function as the view server "log(stuff);"
to do this. Note this is not for use on production DBs due to heavy
perf impact.

Pro-tip: don't forget to accept all _deleted docs through your
function to ensure MVCC continues to work as expected.
