Mark Hammond updated COUCHDB-452:
---------------------------------
Attachment: dont_log_error_on_disconnect.patch
Patch which causes a simple:
[info] [<0.66.0>] remote connection dropped prematurely
record to be written. jchris also suggested I remove the error:badarg and
error:function_clause handlers as these are picked up by the Tag:Error handler
- so they have gone too.
> couch logs an [error] record if a client disconnects

>
> 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.
