Hello,
I've installed ejabberd 13.12 using the binary installer for linux 64 Bit on Debian wheezy 7.3
Everything works as expected except the fact that the lib libyaml-0-2 is missing, so installing it before running Ejabberd binary installer.
My problem here is that I've installed mod_admin_extra but it is not working at all.
My configuration:
- Debian Wheezy 7.3 64 Bit
- Ejabberd 13.12
- vHost: xmpp.mydomain.com
- Auth : internal
I've:
1 - downloaded the erl file from git
2 - compiled it using this command
./ercl -I /op/ejabberd-13.12/lib/ejabberd-13.12/include /user/neodolphin/mod_admin_extra.erl
3 - copied the beam file in the folder
/opt/ejabberd-13.12/lib/ejabberd-13.12/ebin/
4 - Modified the configuration file ejabberd.yml to enable mod_admin_extra with this line
mod_admin_extra: {}5 - restarted ejabberd
When I type :
./ejabberdctl srg_list xmpp.mydomain.com
the command return me nothing but on the web site I can see my two Share Roster Group
I have launch a debug using :
./ejabberdctl debug
then typed
lists:sort(mod_shared_roster:list_groups('xmpp.mydomain.com')).which is corresponding in the source code to the function srg_list and this command return me
[]
If you have any idea :)
UPDATE: I've dug deeper in
UPDATE:
I've dug deeper in the code.
The command srg_list give you this code mod_shared_roster:list_groups(Host) which correspond to list_groups(Host, gen_mod:db_type(Host, ?MODULE)). since the db_type I'm using is mnesia I take the function list_groups(Host, mnesia).
This function give me this code:
mnesia:dirty_select(sr_group,[{#sr_group{group_host = {'$1', '$2'}, _ = '_'},
[{'==', '$2', Host}], ['$1']}]);
If I copy and paste this code it gives me this error: record sr_group undefined
From then I've done a basic select on the sr_group table using this code :
F = fun() -> mnesia:select('sr_group',[{'_',[],['$_']}]) end,mnesia:activity(transaction, F).
and this gave this result :
[{sr_group,{<<"SharedRosterTest1">>,<<"xmpp.mydomain.com">>},[{name,<<"SharedRosterTest1">>},
{displayed_groups,[<<"SharedRosterTest1">>,<<"SharedRosterTest2">>]}]},
{sr_group,{<<"SharedRosterTest2">>,<<"xmpp.mydomain.com">>},
[{name,<<"SharedRosterTest2">>},
{displayed_groups,[<<"SharedRosterTest2">>]},
{all_users,true}]}]
So I tried to modified the dirty_select to a select because it is the same according the mnesia documentation here :
Here the modified version
F = fun() ->Host = 'xmpp.mydomain.com',
MatchHead = #sr_group{group_host = {'$1', '$2'}, _ = '_'},
Guard = {'==', '$2', Host},
Result = '$1',
mnesia:select('sr_group',[{MatchHead, [Guard], [Result]}]) end,
mnesia:activity(transaction, F).
and this give the same error : * 3: record sr_group undefined
So I dug deeper in the mnesia database and in the table sr_group using this command mnesia:schema(sr_group)
Here is the result:

ok
As we see the record sr_group exist and the group_host attribute also as written in the original dirty_select
So after a little google I've seen that in erlang you have to define the record in the shell before using it so fair enough I've user this command rd(sr_group, {group_host, opts})
then I can select with
mnesia:dirty_select(sr_group, [{#sr_group{group_host = {'$1', '$2'}, _ = '_'}, [{'==', '$2', 'xmpp.mydomain.com'}], ['$1']}]).but it return me nothing.
mnesia:dirty_select(sr_group, [{#sr_group{group_host = {'$1', '$2'}, _ = '_'}, [], ['$2']}]).returns me
[<<"SharedRosterTest1">>,<<"SharedRosterTest1">>,'test']Note the test at the end, this one has been created with mod_admin_extra:srg_create so I see that when your creating a shared roster using the webadmin you can't retreive it using srg_list.
You have to create it using srg_create
I think it is a bug because when you type ejabberdctl with a command from admin extra it dose interpret well the argument
