Handle missing SIGHUP on Windows

[rtr1]

SIGHUP is not present on Windows, so the crontask management command crashes with AttributeError: module 'signal' has no attribute 'SIGHUP'.

If I change these lines in crontask.py:

def launch_scheduler(self, lock, scheduler):
    signal.signal(signal.SIGHUP, kill_softly)

To this:

def launch_scheduler(self, lock, scheduler):
    if hasattr(signal, "SIGHUP"):
        signal.signal(signal.SIGHUP, kill_softly)

Then it works on Windows, and CTRL-C sends SIGINT and stops the worker as expected.

Hi @rtr1 👋,

Thanks for reaching out! I see; I haven't tested this on Windows yet. We should add Windows and macOS to the CI suite too.

I'll let my robot-buddy have a shot at this!

Thanks!
Joe
