Description frederic heem 2006-09-21 08:38:53 UTC

Inside a server callback (those that are magically called by the glib 
bindings), dbus_connection_get_unix_user is called to get the user id of the 
client but fails. In _dbus_auth_get_identity, it copies the 
credentials : "*credentials = auth->authorized_identity". 
All fields of auth->authorized_identity are set to DBUS_PID_UNSET.
Any ideas ?

Comment 1 John (J5) Palmieri 2006-09-24 09:23:14 UTC

Are you calling DBusConnection methods on a DBusGConnection?

Comment 2 frederic heem 2006-10-03 01:37:24 UTC

dbus_g_connection_get_connection is used to convert DBusGConnection to  
DBusConnection. Hence, dbus_connection_get_unix_user gets the correct 
connection.

Comment 3 John (J5) Palmieri 2006-10-03 08:05:30 UTC

closing

Comment 4 frederic heem 2006-10-04 01:36:40 UTC

There is a misunderstanding, dbus_connection_get_unix_user gets the correct 
connection but fails.
Actually, I cannot any unit test case for dbus_connection_get_unix_user in 
dbus.

Comment 5 Havoc Pennington 2006-10-04 06:10:12 UTC

are you using a tcp connection, or on windows? it won't work in either of 
those cases.

Comment 6 frederic heem 2006-10-04 06:56:51 UTC

Neither tcp nor windows is used

Comment 7 John (J5) Palmieri 2006-10-04 07:29:13 UTC

Do you have a test case you can attach?  What version of D-Bus are you using and
on what distribution?

BTW Sorry about closing the bug.  I thought you said you used the get_connection
API and get_unix_user worked.

Comment 8 frederic heem 2006-10-04 07:34:08 UTC

dbus 0.93, dbus-glib-0.73, fedora core 5
For the test case, just call dbus_connection_get_unix_user inside a call back 
that are called by the glib binding

Comment 9 John (J5) Palmieri 2006-10-04 07:48:19 UTC

Attaching a test case would be nice because of time constraints and we would be
sure that it fails on your machine.

Comment 10 frederic heem 2006-10-04 08:00:04 UTC

The easiest way would be to add a permanent test case in test-dbus-glib.c

Comment 11 John (J5) Palmieri 2006-10-28 05:42:47 UTC

As it turns out the code in question was trying to get the unix user from a
connection which was opened by the app.  You can only get the unix user off of
connections passed to a server.  I am not sure if the glib bindings can do this
yet.  The best place to ask is on the mailing list
