Tcl Version: 8.3.4
OS :Unix platforms
Tcl_AsyncMark doesn't awaken the Notifier (see defect
#217934 )
This problem still exists on non-threaded versions of
Tcl. Tcl_AlertNotifier does nothing if TCL_THREADS is
not defined:
void
Tcl_AlertNotifier(clientData)
ClientData clientData;
{
#ifdef TCL_THREADS
ThreadSpecificData *tsdPtr = (ThreadSpecificData *)
clientData;
Tcl_MutexLock(¬ifierMutex);
tsdPtr->eventReady = 1;
Tcl_ConditionNotify(&tsdPtr->waitCV);
Tcl_MutexUnlock(¬ifierMutex);
#endif
}
So if Tcl is blocked in a select statement (as in a
socket event driven application), events posted to the
Tcl event queue via Tcl_AsyncMark don't get handled
until an unrelated event kicks Tcl out of the select
statement.
