t.i.t.Connection(abstract.FileDescriptor, _SocketCloser) : class documentation

Initiate TLS negotiation.

Parameters

contextFactory

A context factory (see ssl.py)

Reliably write some data.

The data is buffered until the underlying file descriptor is ready for writing. If there is more than self.bufferSize data in the buffer and this descriptor has a registered streaming producer, its pauseProducing() method will be called.

Reliably write a sequence of data.

Currently, this is a convenience method roughly equivalent to:

   for chunk in iovec:
       fd.write(chunk)

It may have a more efficient implementation at a later time or in a different reactor.

As with the write() method, if a buffer size limit is reached and a streaming producer is registered, it will be paused until the buffered data is written to the underlying file descriptor.

Called when data can be written.

A result that is true (which will be a negative number) implies the connection was lost. A false result implies the connection is still there; a result of 0 implies no write was done, and a result of None indicates that a write was done.

Return the socket for this connection.

Calls self.protocol.dataReceived with all available data.

This reads up to self.bufferSize bytes of data from its socket, then calls self.dataReceived(data) to process it. If the connection is not lost through an error in the physical recv(), this function will return the result of the dataReceived call.

Connection.writeSomeData(data) -> #of bytes written | CONNECTION_LOST This writes as much data as possible to the socket and returns either the number of bytes read (which is positive) or a connection error code (which is negative)

Indicates read connection was lost.

See abstract.FileDescriptor.connectionLost().

Return the prefix to log with when I own the logging thread.

Return if TCP_NODELAY is enabled.

Enable/disable TCP_NODELAY.

Enabling TCP_NODELAY turns off Nagle's algorithm. Small packets are sent sooner, possibly at the expense of overall throughput.

Return if SO_KEEPALIVE is enabled.

Enable/disable SO_KEEPALIVE.

Enabling SO_KEEPALIVE sends packets periodically when the connection is otherwise idle, usually once every two hours. They are intended to allow detection of lost peers in a non-infinite amount of time.
