[jira] [Commented] (COUCHDB-1295) couch_util:collate/3 leaks ports

["Robert Newson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-1295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13112495#comment-13112495 ] 

Robert Newson commented on COUCHDB-1295:
----------------------------------------

drv_port() stores the port in the process dictionary and reuses it so unless ports aren't freed when processes die, there's no leak. I'm pretty confident erlang cleans up open ports and file descriptors associated with processes, but I can't verify right now.

> couch_util:collate/3 opens a port but never closes nor links to it. Unless I am missing something, it leaks ports. The most trivial solution that comes to mind is to link to the said port but I had problems with it as those processes didn't seem to die therefore port leakage continued.
> Explicitly closing port after every operation seems to do the trick so far, but I admit it is an ugly solution.
> Any ideas?
