New submission from Donghyun Kim <uryan...@gmail.com>:
During implement simple forking TCP server, I got the hang-up child
process binding listen socket which caused parent(listen/accept)
restarting failed. (port in use)
Because child process does something with connected socket, there's no
need to bind listen socket in child process.
(finish_request() calls RequestHandlerClass with connected socket(=request))
Simply add self.socket.close() in the beginning of forked child process.
SocketServer.ForkingMixIn :
def process_request(self, request, client_address):
"""Fork a new subprocess to process the request."""
self.collect_children()
pid = os.fork()
if pid:
# Parent process
if self.active_children is None:
self.active_children = []
self.active_children.append(pid)
self.close_request(request)
return
else:
# Child process.
# This must never return, hence os._exit()!
self.socket.close() # close parent's listen socket in child
try:
self.finish_request(request, client_address)
os._exit(0)
except:
try:
self.handle_error(request, client_address)
finally:
os._exit(1)
