Threading problems with gnome-vfs & initialization
+ could it be gconf causing problems ?
gconf_orb = CORBA_ORB_init (&argc, argv, "orbit-local-orb", &ev);
+ nope - the ORB is thread-safe by default
+ also does a g_thread_init
=> fine ...
static void
gnome_vfs_thread_init (void)
{
private_is_primary_thread = g_private_new (NULL);
g_private_set (private_is_primary_thread, GUINT_TO_POINTER (1));
_gnome_vfs_module_callback_private_init ();
_gnome_vfs_async_job_map_init ();
_gnome_vfs_thread_pool_init ();
_gnome_vfs_job_queue_init ();
}
** And **
gboolean
gnome_vfs_is_primary_thread (void)
{
if (g_thread_supported()) {
return GPOINTER_TO_UINT(g_private_get (private_is_primary_thread)) == 1;
} else {
return TRUE;
}
}
+ gnome_vfs_is_primary_thread not called explicitely
*** URGH ***
+ #define GNOME_VFS_ASSERT_PRIMARY_THREAD g_assert (gnome_vfs_is_primary_thread())
+ #define GNOME_VFS_ASSERT_SECONDARY_THREAD g_assert (!gnome_vfs_is_primary_thread())
+ not used inside gnome-vfs itself either ...
Hmm...
gboolean
gnome_vfs_init (void)
{
if (!g_thread_supported ())
g_thread_init (NULL);
gnome_vfs_thread_init ();
if (bonobo_activation_orb_get() == NULL)
bonobo_activation_init (0, bogus_argv);
bonobo_init (NULL, bogus_argv);
retval = gnome_vfs_method_init ();
retval = _gnome_vfs_configuration_init ();
signal (SIGPIPE, SIG_IGN);
}
=> ORB initialization ...
+ assuming we initialize the ORB 1st ...
+ that -does- store a 'primary thread' concept.
+ giop.c (giop_init)
+ sets 'giop_main_thread' to be the one with the
g_main_context_default() association;
+ sets that thread's thread data to be that ...
=> Using PostUserEvent:
BOOL Application::PostUserEvent( ULONG& rEventId, ULONG nEvent, void* pEventData )
{
ImplSVEvent* pSVEvent = new ImplSVEvent;
pSVEvent->mnEvent = nEvent;
pSVEvent->mpData = pEventData;
pSVEvent->mpLink = NULL;
pSVEvent->mpWindow = NULL;
pSVEvent->mbCall = TRUE;
rEventId = (ULONG)pSVEvent;
if ( ImplGetDefaultWindow()->ImplGetFrame()->PostEvent( pSVEvent ) )
return TRUE;
else
{
rEventId = 0;
delete pSVEvent;
return FALSE;
}
}
->
BOOL GtkSalFrame::PostEvent( void* pData )
{
getDisplay()->SendInternalEvent( this, pData );
return TRUE;
}
vcl/unx/source/app/saldisp.cxx:
void SalDisplay::SendInternalEvent( SalFrame* pFrame, void* pData, USHORT nEvent )
{
if( osl_acquireMutex( hEventGuard_ ) )
{
m_aUserEvents.push_back( SalUserEvent( pFrame, pData, nEvent ) );
// Notify SalXLib::Yield() of a pending event.
pXLib_->PostUserEvent();
osl_releaseMutex( hEventGuard_ );
}
}
+ pushes to m_aUserEvents ...
