It is said all over the documentation
That when connection is accepted the new *instance* of
a protocol is created. However as it is single
threaded, can use the same instance?
For example (In case of UDP):
port = x;
#some proto subclass of AbstractDatagramProtocol
#this protocol does not does nt delegate request to
threads. I assume request is served quickly
proto = Proto()
for if in ("eth0", "eth1")
addr = getAddr(if)
reactor.listenUDP(port, proto, interface = addr,)
I want to have same protocol *instance running* for
diff interface on same port. As this protocol does not
store any state.
Also instead of creating one when connection comes and
descard is when connection is broken. Use a single
however, internet/protocol.py does not allow it?
def makeConnection(self, transport):
assert self.transport == None
self.transport = transport
Can not i use the same instance of the protocol for
each connection instead of getting new instance every
time. As it is single threaded and it must return
before next connection in q is served?
I am once the datagramReceived is call, it must return
before any other request is served. (i am not using
Q1) Am i missing some concept?
Q2) What if the request is delegated to deferrer or
threads, can we still use the same instance of
Q3) What are the ways to create deferrer itself
There is little about it, reactor callfromthread or
callinthread? Any good doc?
