I do something similar with the help of a shell script - roughly like #!/bin/sh touch START_SERVER while [ -f START_SERVER ] do rm START_SERVER thisDir=`pwd | gawk -F '/' '{print $NF}'` twistd --pidfile=${thisDir}.pid -noy che.tac > /dev/null & done echo Server ${thisDir} stopped. -------------------------------------------------------------------- # Close connections, tell clients whether we're stopping or restarting, ...... def _stopServer(self, restart): if restart: f = open('START_SERVER', 'w') f.close() reactor.stop() sys.exit() Harald -----Original Message----- From: Grant McDonald [mailto:gmcdonald@infocomp.com] Sent: torsdag, 24 mars 2005 07:38 To: Twisted general discussion (E-mail) Subject: [Twisted-Python] Bootstrapping Servers Dear All, I have created some code to close all active connections to a server, spawn a new instance of itself and call reactor.stop() to facilitate a remote bootstrap restart of a server. The bootstrapping process takes place through a loader where if passed an option to bootstrap the code pauses for 20 secs to allow the previous process to exit: import sys if sys.argv[1] == "--bootstrap" or sys.argv[1] == "-b": print 'bootstrapping' del sys.argv[1] import time time.sleep(20.0) from twisted.python.runtime import platformType if platformType == "win32": from twisted.scripts.twistw import run else: from twisted.scripts.twistd import run run() However the above code does not allow the server to start since twistd complains that the port is in use: 2005/03/24 17:14 AUS Eastern Daylight Time [-] Log opened. 2005/03/24 17:14 AUS Eastern Daylight Time [-] twistd 1.3.0 (C:\Python23\python.exe 2.3.3) starting up 2005/03/24 17:14 AUS Eastern Daylight Time [-] reactor class: twisted.internet.default.SelectReactor 2005/03/24 17:14 AUS Eastern Daylight Time [-] managers.ConnectionManager starting on 12005 2005/03/24 17:14 AUS Eastern Daylight Time [-] Traceback (most recent call last): 2005/03/24 17:14 AUS Eastern Daylight Time [-] File "D:\python projects\programs\zcfscheduler\loader.py", line 15, in ? 2005/03/24 17:14 AUS Eastern Daylight Time [-] run() <-- snip --> 2005/03/24 17:14 AUS Eastern Daylight Time [-] return getattr(reactor, 'listen'+self.method)(*self.args, **self.kwargs) 2005/03/24 17:14 AUS Eastern Daylight Time [-] File "C:\Python23\lib\site-packages\twisted\internet\default.py", line 283, in listenTCP 2005/03/24 17:14 AUS Eastern Daylight Time [-] p.startListening() 2005/03/24 17:14 AUS Eastern Daylight Time [-] File "C:\Python23\lib\site-packages\twisted\internet\tcp.py", line 594, in startListening 2005/03/24 17:14 AUS Eastern Daylight Time [-] raise CannotListenError, (self.interface, self.port, le) 2005/03/24 17:14 AUS Eastern Daylight Time [-] twisted.internet.error.CannotListenError: Couldn't listen on any:12005: (10048, 'Address already in use'). how can i get the server to stop, restart itself and release the port in the process?
