class twisted.conch.ssh.session.SSHSessionProcessProtocol(protocol.ProcessProtocol): (source)
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 |
| Instance Variable | session | Undocumented |
| Instance Variable | lostOutOrErrFlag | 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 an iterable of byte strings to the physical connection. |
| Method | loseConnection | Close my connection, after writing all pending data. |
| Instance Variable | _signalValuesToNames | Undocumented |
| 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):
| Instance Variable | connected | Undocumented |
| Instance Variable | transport | Undocumented |
| Method | makeConnection | Make a connection to a transport and a server. |
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.
EOF should only be sent when both STDOUT and STDERR have been closed.
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.
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.
| Parameters | data | The data to write. |
Write an iterable of byte 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 byte string.
| Parameters | seq | Undocumented |
| data | The data to write. |
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.
