Tried with the code:
def application(environ, start_response):
import ctypes
ctypes.windll.libhttpd.ap_signal_parent(1)
result = "restart tried"
start_response("200 OK", [
("Content-Type", "text/plain; charset=UTF-8"),
("Content-Length", str(len(result)))])
return [result]
You'll notice several things from the error log, #1 I should really
update to the latest minor version of several things, #2 seems to have
gone down and come back up again fine. A small amount of further
testing didn't show up any obvious issues.
Not sure how pleasant an idea doing this is for every script change
is, at least with httpd -k restart you know when it's happening.
