twisted.protocols.haproxy._v2parser.V2Parser : API documentation

def __init__(self): (source)

Undocumented

def feed(self, data): (source)

Consume a chunk of data and attempt to parse it.

Parameters	data	A bytestring. (type: bytes)
Returns	A two-tuple containing, in order, a `_interfaces.IProxyInfo` and any bytes fed to the parser that followed the end of the header. Both of these values are None until a complete header is parsed.
Raises	InvalidProxyHeader	If the bytes fed to the parser create an invalid PROXY header.

@staticmethod
def _bytesToIPv4(bytestring): (source)

Convert packed 32-bit IPv4 address bytes into a dotted-quad ASCII bytes representation of that address.

Parameters	bytestring	4 octets representing an IPv4 address. (type: `bytes`)
Returns	a dotted-quad notation IPv4 address. (type: `bytes`)

@staticmethod
def _bytesToIPv6(bytestring): (source)

Convert packed 128-bit IPv6 address bytes into a colon-separated ASCII bytes representation of that address.

Parameters	bytestring	16 octets representing an IPv6 address. (type: `bytes`)
Returns	a dotted-quad notation IPv6 address. (type: `bytes`)

@classmethod
def parse(cls, line): (source)

Parse a bytestring as a full PROXY protocol header.

Parameters	line	A bytestring that represents a valid HAProxy PROXY protocol version 2 header. (type: bytes)
Returns	A `_interfaces.IProxyInfo` containing the parsed data.
Raises	InvalidProxyHeader	If the bytestring does not represent a valid PROXY header.

Method	__init__	Undocumented
Method	feed	Consume a chunk of data and attempt to parse it.
Class Method	parse	Parse a bytestring as a full PROXY protocol header.
Static Method	_bytesToIPv4	Convert packed 32-bit IPv4 address bytes into a dotted-quad ASCII bytes representation of that address.
Static Method	_bytesToIPv6	Convert packed 128-bit IPv6 address bytes into a colon-separated ASCII bytes representation of that address.
