View In Hierarchy

Postfix mail transport agent TCP map protocol implementation.

Receive requests for data matching given key via lineReceived, asks it's factory for the data with self.factory.get(key), and returns the data to the requester. None means no entry found.

You can use postfix's postmap to test the map service:

/usr/sbin/postmap -q KEY tcp:localhost:4242

Method connection​Made Called when a connection is made.
Method do​_get Undocumented
Method do​_put Undocumented
Method line​Received Override this for when each line is received.
Method send​Code Send an SMTP-like code with a message.
Class Variable delimiter Undocumented
Class Variable timeout Undocumented
Method _cb​Got Undocumented
Method _cb​Not Undocumented

Inherited from LineReceiver:

Method clear​Line​Buffer Clear buffered data.
Method data​Received Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)
Method line​Length​Exceeded Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.
Method raw​Data​Received Override this for when raw data is received.
Method send​Line Sends a line to the other end of the connection.
Method set​Line​Mode Sets the line-mode of this receiver.
Method set​Raw​Mode Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived.
Constant MAX​_LENGTH The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
Instance Variable line​_mode Undocumented
Instance Variable _buffer Undocumented
Instance Variable _busy​Receiving Undocumented

Inherited from Protocol (via LineReceiver):

Method connection​Lost Called when the connection is shut down.
Method log​Prefix Return a prefix matching the class name, to identify log messages related to this protocol instance.
Class Variable factory Undocumented

Inherited from BaseProtocol (via LineReceiver, Protocol):

Method make​Connection Make a connection to a transport and a server.
Instance Variable connected Undocumented
Instance Variable transport Undocumented

Inherited from _PauseableMixin (via LineReceiver):

Method pause​Producing Undocumented
Method resume​Producing Undocumented
Method stop​Producing Undocumented
Instance Variable paused Undocumented

Inherited from TimeoutMixin:

Method call​Later Wrapper around reactor.callLater for test purpose.
Method reset​Timeout Reset the timeout count down.
Method set​Timeout Change the timeout period
Method timeout​Connection Called when the connection times out.
Instance Variable time​Out The number of seconds after which to timeout the connection.
Method __timed​Out Undocumented
Instance Variable __timeout​Call Undocumented
def connectionMade(self): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.internet.protocol.BaseProtocol.connectionMade

Called when a connection is made.

This may be considered the initializer of the protocol, because it is called when the connection is completed. For clients, this is called once the connection to the server has been established; for servers, this is called after an accept() call stops blocking and a socket has been received. If you need to send any greeting or initial message, do it here.
