* util.pubsub: Add support for limiting number of items to retrieveKim Alvefur2021-09-051-1/+6
| | | | | Hopefully this will eventually be upgraded to RSM, which is why the argument is called 'resultspec' and is a table.
* util.pubsub: Signal that 'persistent-items' is unsupported when disabledKim Alvefur2021-07-221-3/+4
| | | | | | XEP-0060 says that this the way to indicate that 'persistent-items' is unsupported, but doesn't explicitly say if it being disabled in the node configuration also counts as unsupported.
* util.pubsub: Fix behavior of persist_items disabledKim Alvefur2021-07-221-7/+22
| | | | | | | | | | | | | When set to 'false' there is no need for a persistence interface at all, since items are not persisted after being broadcast. Had started wondering if maybe the behavior was wrong, after reading parts of XEP-0060 that pointed in that direction. Some discussion of this can be found in logs of xmpp:xsf@muc.xmpp.org?join from around 2021-07-20 Thanks to Ralph for confirming.
* mod_pubsub: Explicitly enable persistence by default to preserve behaviorKim Alvefur2021-07-211-1/+1
| | | | | | Since nodes were always persistent according to the XEP-0060 definition. Whether data is stored in memory or on disk was not what this setting was meant for.
* util.pubsub: Handle absence of node data interfaceKim Alvefur2021-07-211-17/+32
| | | | | | | | This is in preparation for fixing the behavior of 'persist_items', which was misunderstood at some point. In mod_pep it toggles between persistent storage and in-memory storage, while the correct behavior would be to toggle whether published items are stored at all or forgotten after being broadcast.

* Backed out changeset 27d800ddc3b0 (see below)Matthew Wild2018-08-181-2/+2
| | | | | | | | | It's uncertain whether item not existing should be success and nil, or fail with an error. XEP-0060's "fetch most recent item" actually fetches a list of up to N items. N here is a maximum, not a minimum. The feeling is that no items is simply an empty list, not a failure of the operation.

* util.pubsub: Pass "retract" as the type of such broadcastsKim Alvefur2018-08-161-1/+1
| | | | | | | | This moves some XEP-0060 awkwardness out of util.pubsub and into mod_pubsub A retraction is broadcast in an <items> container, whereas most other kinds of broadcasts are in a container with a name matching the 'kind' attribute.

* util.pubsub: For open nodes, default affiliation is "member"Matthew Wild2018-08-091-1/+1
| | | | | | | | | This allows entities without an explicit affiliation to retrieve items, which is specified by the XEP. Table 6: "Node Access Models" states that for 'open' nodes, "any entity may retrieve items from the node". See also discussion at: https://mail.jabber.org/pipermail/standards/2018-August/035320.html
