Windows Vista Signals

Sep 14th, 2008

Thanks in advance for the help.

I’m fairly new to Python so please forgive me if I don’t quite use the correct terminology.

I have a very simple serial port interface (non-gui) application that I run on windows. Upon closing the window, I want the program to run some cleanup code (ie. Close output files and ports). Originally, on Windows XP (32-bit), using the SIGBREAK signal, it runs my cleanup code as expected when the ‘X’ in the top right corner of the window is pressed. When I run the same program on Windows Vista, it does not run the cleanup code when the window is closed. CTRL+C on both operating systems run the cleanup code as expected. Here is a sample:

def cleanup(signum, frame):
    # cleanup code here  
    print "programmed cleaned up"
 
signal.signal(signal.SIGBREAK, cleanup)
signal.signal(signal.SIGABRT, cleanup)
signal.signal(signal.SIGINT, cleanup)
signal.signal(signal.SIGTERM, cleanup)
signal.signal(signal.SIGFPE, cleanup)
signal.signal(signal.SIGILL, cleanup)
signal.signal(signal.SIGSEGV, cleanup)
def cleanup(signum, frame):
    # cleanup code here  
    print "programmed cleaned up"

signal.signal(signal.SIGBREAK, cleanup)
signal.signal(signal.SIGABRT, cleanup)
signal.signal(signal.SIGINT, cleanup)
signal.signal(signal.SIGTERM, cleanup)
signal.signal(signal.SIGFPE, cleanup)
signal.signal(signal.SIGILL, cleanup)
signal.signal(signal.SIGSEGV, cleanup)

Does anyone know any way that I can run cleanup code on a windows vista machine when the window is closed via the ‘X’ in the top right corner of the screen?

By the way, I've also tried the atexit module and the try: except: finally: any they didn't work either. Maybe I'm not using them correctly

Thanks again.
