Sebastian Rothbucher created COUCHDB-2989:
---------------------------------------------
Summary: Too little timeout causes _changes to crash
Key: COUCHDB-2989
URL: https://issues.apache.org/jira/browse/COUCHDB-2989
Project: CouchDB
Issue Type: Bug
Components: BigCouch
Reporter: Sebastian Rothbucher
Reproduce: create a DB, pull changes (here: copied from changes.js test cases
as eventsource): this will still work; create a doc, pull changes again with
very small timeout: crashes. Leaving the timeout out or specifying a sufficient
one will work OK. Otherwise, the stream will abort with HTTP 500 (which in fact
is not valid for chunked transfer (i.e. causes a cryptic libcurl/curl error
message).
Use curl --raw for testing, so you see the effect.
Here's the log:
