                      PostfixTCPMapServer

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

	`do_put(self, keyAndValue)`
	`lineReceived(self, line)` Override this for when each line is received.
	`sendCode(self, code, message)` Send an SMTP-like code with a message.
Inherited from LineReceiver
	`clearLineBuffer(self)` Clear buffered data.
	`dataReceived(self, data)` Protocol.dataReceived.
	`lineLengthExceeded(self, line)` Called when the maximum line length has been reached.
	`rawDataReceived(self, data)` Override this for when raw data is received.
	`sendLine(self, line)` Sends a line to the other end of the connection.
	`setLineMode(self, extra)` Sets the line-mode of this receiver.
	`setRawMode(self)` Sets the raw mode of this receiver.
Inherited from Protocol
	`connectionFailed(self)` (Deprecated)
	`connectionLost(self, reason)` Called when the connection is shut down.
Inherited from BaseProtocol

Class Variable Summary
`str`	`delimiter`: The line-ending delimiter to use.
`int`	`timeout` = 600
Inherited from LineReceiver
`str`	`_LineReceiver__buffer` = `''`
`int`	`line_mode` = 1
`int`	`MAX_LENGTH`: The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped).

`NoneType`	`_TimeoutMixin__lastReceived` = None
`NoneType`	`_TimeoutMixin__timeoutCall` = None
`NoneType`	`timeOut`: The number of seconds after which to timeout the connection.

Method Details

connectionMade(self)

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.

Overrides:: twisted.internet.protocol.BaseProtocol.connectionMade (inherited documentation)

lineReceived(self, line)

Override this for when each line is received.

Overrides:: twisted.protocols.basic.LineReceiver.lineReceived (inherited documentation)

sendCode(self, code, message='')

Send an SMTP-like code with a message.

Class Variable Details

delimiter

The line-ending delimiter to use. By default this is '\r\n'.

Type:: str
Value:: ''' '''

timeout

Type:: int
Value:: 600
