vincnetas opened a new issue #2041: A canceled request to changes spams the log output URL: https://github.com/apache/couchdb/issues/2041 [NOTE]: # ( ^^ Provide a general summary of the issue in the title above. ^^ ) ## Description Canceling _changes request produces [error] level log in CDB. With big amount of users on unreliable connections listening for changes in CDB, log gets flooded with error messages which are actually not errors. This affects also _stats endpoint which reports number of 500 errors, which makes monitoring for real errors impossible. ## Steps to Reproduce Start docker : ``` docker run \ -d --name couch_db \ -p 5984:5984 \ --env COUCHDB_USER=admin \ --env COUCHDB_PASSWORD=thisiscouchdb \ --env NODENAME=127.0.0.1 couchdb:2.3.1 ``` Create users DB `curl -X PUT http://127.0.0.1:5984/_users -u admin` Initiate request for changes `curl "http://127.0.0.1:5984/_users/_changes?feed=longpoll&heartbeat=10000&since=now&limit=25"; -u admin` Cancel it with Ctrl+C After 30 seconds error message gets logged (docker logs couch_db) ``` [error] 2019-05-31T10:29:16.271783Z [email protected] <0.3233.0> 717801f155 req_err(1125717067) unknown_error : normal [<<"chttpd:catch_error/3 L356">>,<<"chttpd:handle_req_after_auth/2 L322">>,<<"chttpd:process_request/1 L303">>,<<"chttpd:handle_request_int/1 L243">>,<<"mochiweb_http:headers/6 L128">>,<<"proc_lib:init_p_do_apply/3 L247">>] ``` ## Expected Behaviour Canceling _changes request should not produce error level log message ## Your Environment 2.3.1 official couchdb docker image * CouchDB Version used: 2.3.1 * Browser name and version: curl * Operating System and version: osx
