From 5f98d0cc2359f1ab55b7af8179981592a3508faa Mon Sep 17 00:00:00 2001 From: Matthew Wild Date: Wed, 22 Mar 2023 11:39:19 +0000 Subject: mod_pubsub, mod_pep: Support per-node configurable inclusion of publisher This matches ejabberd's behaviour, using the 'pubsub#itemreply' config option. Although the current definition of this option in the specification is not as clear as it could be, I think matching what existing deployments do is the best option to resolve the ambiguity and reduce fragmentation. We should update the spec to be clearer about how to use and interpret this option. The 'expose_publisher' option for mod_pubsub is now an override (always expose or never expose). If unset, it will use the per-node config (which defaults to not exposing). Thanks to Link Mauve, edhelas and goffi for sparking this feature. --- plugins/mod_pep.lua | 7 +++++++ plugins/mod_pubsub/mod_pubsub.lua | 12 ++++++++---- plugins/mod_pubsub/pubsub.lib.lua | 21 +++++++++++++++++++++ 3 files changed, 36 insertions(+), 4 deletions(-) diff --git a/plugins/mod_pep.lua b/plugins/mod_pep.lua index 71e45e7c..c7afde6f 100644 --- a/plugins/mod_pep.lua +++ b/plugins/mod_pep.lua @@ -136,10 +136,14 @@ end local function get_broadcaster(username) local user_bare = jid_join(username, host); local function simple_broadcast(kind, node, jids, item, _, node_obj) + local expose_publisher; if node_obj then if node_obj.config["notify_"..kind] == false then return; end + if node_obj.config.itemreply == "publisher" then + expose_publisher = true; + end end if kind == "retract" then kind = "items"; -- XEP-0060 signals retraction in an container @@ -151,6 +155,9 @@ local function get_broadcaster(username) if node_obj and node_obj.config.include_payload == false then item:maptags(function () return nil; end); end + if not expose_publisher then + item.attr.publisher = nil; + end end end diff --git a/plugins/mod_pubsub/mod_pubsub.lua b/plugins/mod_pubsub/mod_pubsub.lua index f51e8fe4..d66c31b7 100644 --- a/plugins/mod_pubsub/mod_pubsub.lua +++ b/plugins/mod_pubsub/mod_pubsub.lua @@ -12,7 +12,7 @@ local xmlns_pubsub_owner = "http://jabber.org/protocol/pubsub#owner"; local autocreate_on_publish = module:get_option_boolean("autocreate_on_publish", false); local autocreate_on_subscribe = module:get_option_boolean("autocreate_on_subscribe", false); local pubsub_disco_name = module:get_option_string("name", "Prosody PubSub Service"); -local expose_publisher = module:get_option_boolean("expose_publisher", false) +local service_expose_publisher = module:get_option_boolean("expose_publisher") local service; @@ -81,7 +81,11 @@ function simple_broadcast(kind, node, jids, item, actor, node_obj, service) --lu if node_obj and node_obj.config.include_payload == false then item:maptags(function () return nil; end); end - if not expose_publisher then + local node_expose_publisher = service_expose_publisher; + if node_expose_publisher == nil and node_obj and node_obj.config.itemreply == "publisher" then + node_expose_publisher = true; + end + if not node_expose_publisher then item.attr.publisher = nil; elseif not item.attr.publisher and actor ~= true then item.attr.publisher = service.config.normalize_jid(actor); @@ -192,7 +196,7 @@ function set_service(new_service) service = new_service; service.config.autocreate_on_publish = autocreate_on_publish; service.config.autocreate_on_subscribe = autocreate_on_subscribe; - service.config.expose_publisher = expose_publisher; + service.config.expose_publisher = service_expose_publisher; service.config.nodestore = node_store; service.config.itemstore = create_simple_itemstore; @@ -219,7 +223,7 @@ function module.load() set_service(pubsub.new({ autocreate_on_publish = autocreate_on_publish; autocreate_on_subscribe = autocreate_on_subscribe; - expose_publisher = expose_publisher; + expose_publisher = service_expose_publisher; node_defaults = { ["persist_items"] = true; diff --git a/plugins/mod_pubsub/pubsub.lib.lua b/plugins/mod_pubsub/pubsub.lib.lua index cd3efb09..829e2b45 100644 --- a/plugins/mod_pubsub/pubsub.lib.lua +++ b/plugins/mod_pubsub/pubsub.lib.lua @@ -164,6 +164,17 @@ local node_config_form = dataform { var = "pubsub#notify_retract"; value = true; }; + { + type = "list-single"; + label = "Specify whose JID to include as the publisher of items"; + name = "pubsub#itemreply"; + var = "itemreply"; + options = { + { label = "Include the node owner's JID", value = "owner" }; + { label = "Include the item publisher's JID", value = "publisher" }; + { label = "Don't include any JID with items", value = "none", default = true }; + }; + }; }; _M.node_config_form = node_config_form; @@ -347,6 +358,13 @@ function handlers.get_items(origin, stanza, items, service) origin.send(pubsub_error_reply(stanza, "nodeid-required")); return true; end + + local node_obj = service.nodes[node]; + if not node_obj then + origin.send(pubsub_error_reply(stanza, "item-not-found")); + return true; + end + local resultspec; -- TODO rsm.get() if items.attr.max_items then resultspec = { max = tonumber(items.attr.max_items) }; @@ -358,6 +376,9 @@ function handlers.get_items(origin, stanza, items, service) end local expose_publisher = service.config.expose_publisher; + if expose_publisher == nil and node_obj.config.itemreply == "publisher" then + expose_publisher = true; + end local data = st.stanza("items", { node = node }); local iter, v, i = ipairs(results); -- cgit v1.2.3
