Hello,
I created a simple ejabberd module to log all the events for roster and presence. I am trying to understand the order of event and the parameters at each event. Everything seem to work except that I am seeing 2 errors in the ejabberd log file and I am not sure how to fix them.
Module Code
start(Host, Opt) ->
?INFO_MSG("Monitor Roster Started for Host (~p) and Opt(~p)...~n", [Host, Opt]),
%%Add the roster hooks here...
ejabberd_hooks:add(roster_process_item, Host, ?MODULE, process_item, 10),
ejabberd_hooks:add(roster_get, Host, ?MODULE, rosterget, 10),
ejabberd_hooks:add(roster_get_jid_info, Host, ?MODULE, rostergetjidinfo, 10),
ejabberd_hooks:add(roster_get_subscription_lists, Host, ?MODULE, rostergetsubscriptionlists, 10),
ejabberd_hooks:add(roster_get_versioning_feature, Host, ?MODULE, rostergetversioningfeature, 10),
ejabberd_hooks:add(roster_groups, Host, ?MODULE, rostergroup, 10),
ejabberd_hooks:add(roster_in_subscription, Host, ?MODULE, rosterinsubscription, 10),
ejabberd_hooks:add(roster_out_subscription, Host, ?MODULE, rosteroutsubscription, 10),
ejabberd_hooks:add(set_presence_hook, Host, ?MODULE, setpresencehook, 1),
%%ejabberd_hooks:add(resend_subscription_requests_hook, Host, ?MODULE, resendsubscriptionrequestshook, 50),
ok.
process_item(Acc, Server) ->
?INFO_MSG("Roster process Item... Acc= ~p~n Server= ~p~n", [Acc, Server]).

setpresencehook(User, Server, Resource, Presence) ->
?INFO_MSG("Set Presence Hook.... User= ~p~n Server= ~p~n Resource= ~p~n Presence= ~p~n", [User, Server, Resource, Presence]),
ok.
resendsubscriptionrequestshook(Acc, User, Server) ->

It means that it tried to call the function rostergetversioningfeature with two arguments, but it isn't defined. What you defined accepts three arguments, not two.
That is correct thanks.
That is correct thanks.
