From 0b783f68d665d829ac036fc34cf9d4eaf57154af Mon Sep 17 00:00:00 2001 From: JC Brand Date: Sun, 19 Apr 2020 21:49:45 +0200 Subject: MUC: Add support for presence probes (fixes #1535) The following patch allows Prosody to respond to `probe` presences and send out the probed occupant's current presence. This is based on line 17.3 in XEP-0045: A MUC service MAY handle presence probes sent to the room JID or an occupant JID (e.g, these might be sent by an occupant's home server to determine if the room is still online or to synchronize presence information if the user or the user's server has gone offline temporarily or has started sharing presence again, as for instance when Stanza Interception and Filtering Technology (XEP-0273) is used). --- plugins/muc/hats.lib.lua | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'plugins/muc/hats.lib.lua') diff --git a/plugins/muc/hats.lib.lua b/plugins/muc/hats.lib.lua index 77051af2..358e5100 100644 --- a/plugins/muc/hats.lib.lua +++ b/plugins/muc/hats.lib.lua @@ -6,8 +6,10 @@ local xmlns_hats = "xmpp:prosody.im/protocol/hats:1"; -- Strip any hats claimed by the client (to prevent spoofing) muc_util.add_filtered_namespace(xmlns_hats); + module:hook("muc-build-occupant-presence", function (event) - local aff_data = event.room:get_affiliation_data(event.occupant.bare_jid); + local bare_jid = event.occupant and event.occupant.bare_jid or event.bare_jid; + local aff_data = event.room:get_affiliation_data(bare_jid); local hats = aff_data and aff_data.hats; if not hats then return; end local hats_el; -- cgit v1.2.3
