Hi there, I'm working on a multi-threaded utility to monitor network connections between three machines The configuration of the three machines are: a web machine that feeds back to two machines for processing. Sometimes when the web connection is closed, the corresponding processes on the two backend machines don't close. How, I have the current set up is:
class web: def __init__(self): <set some stuff> def run(self,args): <loop to get some data> class mach1: def __init__(self): <set some stuff> def run(self,args): <loop to get some data> class mach2: def __init__(self): <set some stuff> def run(self,args): <loop to get some data> class target: def run(self,args): ... collect data from web, mach1, mach2 classes, monitor connections, yada yada yada My question is how to get the information to the target class. The target class must have the web, mach1, mach2 data sets before doing any sort of matching up of information. Now the ways that I have thought of are: -Directing sending the information to the target object (there will only be one) -Using the Observer pattern to send the information from the web, mach1, mach2 classes to the target object And other question that I do have are: -Is there a way to "block" run until I get information from the three other objects. Presently, I can only think of looping and polling to see if the information has come in yet. I'm sure there is a way because I have seen it used in the SocketHandler class. -Is there any way that I can be sure that two different objects are not writing to target at the same time? The present way that I'm thinking about is using locking. Thanks Tino
