Creating and configuring pubsub node -- pubsub#item_expire

Submitted by Ken on Fri, 2009-11-06 02:21

Does 2.1.0 handle the item_expire node configuration option for automatically removing items after a certain number of seconds? It doesn't seem to have any effect when I pass the option, but hopefully I'm just doing something wrong. I really need this feature.

Thanks in advance!

Not implemented

I didn't find in mod_pubsub source code any reference to item_expire. The only similar code found refers to pubsub#expire.

Notice that the option was added to XEP-0060 very recently, and it's yet a work in progress:

Version 1.13rc6 (in progress, 2009-10-01)
 * Added item_expire node configuration option for automatically removing 
items after a certain number of seconds.

And mod_pubsub in ejabberd 2.1.0 uses version 1.12 of the specification as a base.
