Description Etienne Vaillant 2006-11-14 07:49:41 UTC
I'm a very simple program and it crash (with an assert) when i run it.

Program :

#include <stdio.h>
#include <dbus/dbus.h>

int main(void)

 return 0;

with :
 - g++ 4.1.2
 - dbus version 1.0.0

Run :
$ ./run
10501: assertion failed "(functions->mask & ~DBUS_THREAD_FUNCTIONS_ALL_MASK) ==
0" file "dbus-threads.c" line 606 function dbus_threads_init

I think, I found the error : the value of DBUS_THREAD_FUNCTIONS_ALL_MASK on file
dbus/dbus-threads.h. Currently its value is (1 << 13) - 1 and I think, it is
wrong and it woud be (1 << 14) - 1.

changing the threads test to use the default threads instead of the debug
threads as this is a more realworld test.
Comment 2 John (J5) Palmieri 2006-11-14 10:57:38 UTC
fixed with testcase.  Commited to HEAD and DBUS_1_0
Comment 3 Havoc Pennington 2006-11-14 12:57:40 UTC
The only trick there is that the debug threads stuff barfs on recursive thread 
locking, and I was trying to keep things working without recursive locks...
I think it might be good to have a more thread-specific little test program, 
too, just verifying the basic behavior of the thread primitives.
