t.c.s.s.SSHSessionProcessProtocol(protocol.ProcessProtocol) : class documentation

Part of twisted.conch.ssh.session View Source View In Hierarchy

Implements interfaces: twisted.internet.interfaces.ITransport

I am both an IProcessProtocol and an ITransport.

I am a transport to the remote endpoint and a process protocol to the local subsystem.

Method __init__ Undocumented
Method connectionMade Called when a connection is made.
Method outReceived Some data was received from stdout.
Method errReceived Some data was received from stderr.
Method outConnectionLost EOF should only be sent when both STDOUT and STDERR have been closed.
Method errConnectionLost See outConnectionLost().
Method connectionLost Undocumented
Method processEnded When we are told the process ended, try to notify the other side about how the process ended using the exit-signal or exit-status requests. Also, close the channel.
Method getHost Return the host from my session's transport.
Method getPeer Return the peer from my session's transport.
Method write Write some data to the physical connection, in sequence, in a non-blocking fashion.
Method writeSequence Write a list of strings to the physical connection.
Method loseConnection Close my connection, after writing all pending data.
Method _getSignalName Get a signal name given a signal number.

Inherited from ProcessProtocol:

Method childDataReceived Called when data arrives from the child process.
Method childConnectionLost Called when a file descriptor associated with the child process is closed.
Method inConnectionLost This will be called when stdin is closed.
Method processExited This will be called when the subprocess exits.

Inherited from BaseProtocol (via ProcessProtocol):

Method makeConnection Make a connection to a transport and a server.
def __init__(self, session): (source)
Undocumented
def connectionMade(self): (source)
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.

def outReceived(self, data): (source)
Some data was received from stdout.
def errReceived(self, err): (source)
Some data was received from stderr.
def outConnectionLost(self): (source)
EOF should only be sent when both STDOUT and STDERR have been closed.
def errConnectionLost(self): (source)
See outConnectionLost().
def connectionLost(self, reason=None): (source)
Undocumented
def _getSignalName(self, signum): (source)
Get a signal name given a signal number.
def processEnded(self, reason=None): (source)
When we are told the process ended, try to notify the other side about how the process ended using the exit-signal or exit-status requests. Also, close the channel.
def getHost(self): (source)
Return the host from my session's transport.
def getPeer(self): (source)
Return the peer from my session's transport.
def write(self, data): (source)
Write some data to the physical connection, in sequence, in a non-blocking fashion.

If possible, make sure that it is all written. No data will ever be lost, although (obviously) the connection may be closed before it all gets through.

def writeSequence(self, seq): (source)
Write a list of strings to the physical connection.

If possible, make sure that all of the data is written to the socket at once, without first copying it all into a single string.

def loseConnection(self): (source)
Close my connection, after writing all pending data.

Note that if there is a registered producer on a transport it will not be closed until the producer has been unregistered.
