You can already use the approach suggested:
if (PyOS_InterruptOccurred()) goto error
to handle interrupts. The drawback of this approach is that the loop executes more slowly because a check for the interrupt occurs many times in the loop which costs time.
The advantage is that it may work with threads (I'm not clear on whether or not PyOS_InterruptOccurred can be called without the GIL, though).
It should be; it's pure C code:
int PyOS_InterruptOccurred(void) { if (!interrupted) return 0; interrupted = 0; return 1; }
I tried to test this with threads using the following program and it doesn't seem to respond to interrupts. import threading import numpy.core.multiarray as ncm class mythread(threading.Thread): def run(self): print "Starting thread", self.getName() ncm.test_interrupt(1) print "Ending thread", self.getName() m1 = mythread() m2 = mythread() m1.start() m2.start()
