Nick Vatamaniuc commented on COUCHDB-3168:
------------------------------------------
Initially this seemed like a one-line change:
https://github.com/apache/couchdb-couch-replicator/blob/master/src/couch_replicator_api_wrap.erl#L451
However a too large document crashes the whole _bulk_docs request it seems with:
{"error":"too_large","reason":"the request entity is too large"}
This mean we don't know which ones from the list of docs succeeded and which
ones didn't.
I tried this with:
curl -X DELETE http://adm:pass@localhost:15984/x; curl -X PUT
http://adm:pass@localhost:15984/x && curl -d @large_docs.json -H 'Content-Type:
application/json' -X POST http://adm:pass@localhost:15984/x/_bulk_docs
where large_docs.json looked something like
{code}
{
"docs" : [
{"_id" : "doc1"},
{"_id" : "doc2", "large":"x...."}
]
}
{code}
and max docs size was set to something smaller than the "large" value in the
docs
> Replicator doesn't handle writing document to a db which has a limited
> document size

> If a target db has set a smaller document max size, replication crashes.
> It might make sense for the replication to not crash and instead treat
> document size as an implicit replication filter then display doc write
> failures in the stats / task info / completion record of normal replications.
