Subject [jira] Closed: (COUCHDB-355) deleting a _config key sets the value to ""
Date Sun, 19 Jul 2009 21:32:14 GMT


Adam Kocoloski closed COUCHDB-355.

    Resolution: Fixed

r795630 checks for empty config values while we parse an ini value.  If a value is empty,
we interpret that to mean delete the key from the config.

 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.
