      Description

      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.
