PouchDB's MAX_URL_LENGTH is longer than CouchDB 2.3's

[dholth]

pouchdb-abstract-mapreduce limits GET queries to 2000 characters, but my CouchDB 2.3 fails when a URL is more than 1335 characters long (or 1300 characters without the protocol, domain, and port). That means max/reduce queries with a medium number of keys will fail, but normal or very big queries will succeed.

Instead, PouchDB should set a lower MAX_URL_LENGTH here and in the one or two other places that it is in play.

A cursory search of the couchdb and mochiweb source code doesn't tell me where this could be happening.

Turns out this is a regression that will be fixed in CouchDB 2.3.1 or with an explicit buffer size. apache/couchdb#1810
