Subject [jira] Created: (COUCHDB-355) deleting a _config key sets the value to ""
Date Thu, 21 May 2009 14:38:45 GMT
deleting a _config key sets the value to ""
-------------------------------------------

                 Key: COUCHDB-355
                 URL: https://issues.apache.org/jira/browse/COUCHDB-355
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
    Affects Versions: 0.9
            Reporter: Adam Kocoloski


couch_config:delete/2 is implemented as

delete(Section, Key) ->
    set(Section, Key, "").

I think that's misleading -- a key with an empty value is not the same as no key at all. 
Consider the case of an update_notification process.  To me, deleting that key should just
send an EOF to the process.  Instead Couch sends the EOF and then tries to spawn an os_process
to execute "".  The end result is the same, but a few things crash along the way.
