twisted.protocols.haproxy._wrapper.HAProxyProtocolWrapper(policies.ProtocolWrapper, object) class documentationtwisted.protocols.haproxy._wrapper
(View In Hierarchy)
A Protocol wrapper that provides HAProxy support.
This protocol reads the PROXY stream header, v1 or v2, parses the provided connection data, and modifies the behavior of getPeer and getHost to return the data provided by the PROXY header.
| Method | __init__ | Undocumented |
| Method | dataReceived | Called whenever data is received. |
| Method | getPeer | Undocumented |
| Method | getHost | Undocumented |
Inherited from ProtocolWrapper:
| Instance Variable | wrappedProtocol | An IProtocol
provider to which IProtocol
method calls onto this ProtocolWrapper
will be proxied. |
| Instance Variable | factory | The WrappingFactory
which created this ProtocolWrapper. |
| Method | logPrefix | Use a customized log prefix mentioning both the wrapped protocol and the current one. |
| Method | makeConnection | When a connection is made, register this wrapper with its factory, save
the real transport, and connect the wrapped protocol to this ProtocolWrapper
to intercept any transport calls it makes. |
| Method | write | Undocumented |
| Method | writeSequence | Undocumented |
| Method | loseConnection | Undocumented |
| Method | registerProducer | Undocumented |
| Method | unregisterProducer | Undocumented |
| Method | stopConsuming | Undocumented |
| Method | __getattr__ | Undocumented |
| Method | connectionLost | Called when the connection is shut down. |
Inherited from BaseProtocol (via ProtocolWrapper, Protocol):
| Method | connectionMade | Called when a connection is made. |
Called whenever data is received.
Use this method to translate to a higher-level message. Usually, some callback will be made upon the receipt of each complete protocol message.
| Parameters | data | a string of indeterminate length. Please keep in mind that you will probably need to buffer some data, as partial (or multiple) protocol messages may be received! I recommend that unit tests for protocols call through to this method with differing chunk sizes, down to one byte at a time. |
