Eryk Sun <[email protected]> added the comment:
The SIGINT event gets created when the _signal extension module is imported.
Until then, _PyOS_SigintEvent() returns NULL. But currently all code that calls
_PyOS_SigintEvent() assumes it returns a valid handle. This has to be fixed to
support Py_InitializeEx(0).
For example, pysleep could call WinAPI Sleep on the main thread if the
interrupt event isn't configured:
ul_millis = (unsigned long)millisecs;
hInterruptEvent = _PyOS_SigintEvent();
if (ul_millis == 0 || !hInterruptEvent || !_PyOS_IsMainThread()) {
Py_BEGIN_ALLOW_THREADS
Sleep(ul_millis);
Py_END_ALLOW_THREADS
break;
}
