A Preliminary Study on the Causes of program collapse caused by the same process calling the dig interface dbus_g_bus_get.

Problem:

In the past, the interfaces used by the producer were used in different processes, for example:

Connection = dbus_g_bus_get (dbus_bus_system, & error );

There are no problems with multiple calls.

However, recently, different programs are loaded in the same process.

Connection = dbus_g_bus_get (dbus_bus_system, & error );

If a program runs the second program, dbus_g_bus_get () will fail,

Killed System Administrators !!!

 

The initial cause is: the thread lock problem:

After calling the interface initialized by the thread before calling the callback function,

If (! G_thread_supported ()){

G_thread_init (null );

}

Dbus_g_thread_init ();

That's all.
