couch logs an [error] record if a client disconnects
----------------------------------------------------
Key: COUCHDB-452
URL: https://issues.apache.org/jira/browse/COUCHDB-452
Project: CouchDB
Issue Type: Improvement
Reporter: Mark Hammond
If a client makes a request which returns multiple rows (eg, a query) but
disconnects before reading the response, couch logs:
[error] [<0.66.0>] Uncaught error in HTTP request: {exit,normal}
[info] [<0.66.0>] Stacktrace: [{mochiweb_request,send,2},
{couch_httpd,send_chunk,2},
{couch_httpd_view,send_json_view_row,5},
{couch_httpd_view,'-make_view_fold_fun/6-fun-0-',12},
{couch_view,fold_fun,4},
{couch_btree,stream_kv_node2,7},
{couch_btree,stream_kp_node,7},
{couch_btree,fold,5}]
This could lead someone to conclude couch has an error which is not correct. A
simple [info] record recording the premature normal exit is probably more
appropriate.
FYI, the easiest way I found to repro this was to execute:
% python -c "import urllib;
urllib.urlopen('http://127.0.0.1:5984/your_db/_design/your_design_doc/_view/your_view?reduce=false').close()"
which causes Python to open a connection and close it without reading anything.
I'll attach a patch as suggested generally by jchris.
