["Jaime Barrajón (JIRA)" <ji...@apache.org>]

Jaime Barrajón created COUCHDB-2790:
---------------------------------------

             Summary: Requests to non-existent database fill up couchdb log
                 Key: COUCHDB-2790
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2790
             Project: CouchDB
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: Logging
            Reporter: Jaime Barrajón


When requesting a non-existing database, the response is
{"error":"not_found","reason":"no_db_file"}

This generates an error-level log entry in the couchdb log:
[Wed, 26 Aug 2015 12:32:57 GMT] [error] [<0.173.0>] Could not open file /var/lib/couchdb/foo.couch: no such file or directory

We can flood couchdb with invalid requests and fill up the log size pretty fast, eventually filling up the server volume.

I'm using couchdb as a hiera datastore for use with puppet and other scripts.
This makes me change hiera's hierarchy and loose security functionality to avoid crashing the server.

workarounds:
logrotate: it does its job, but does not solve the problem here
nginx as proxy: proxy requests to couchdb filtering from a list of valid urls, one more thing to mantain
