class documentation

class RaisingDNSServerFactory(server.DNSServerFactory): (source)

A server.DNSServerFactory subclass whose methods raise an exception containing the supplied arguments.

Used for stopping messageReceived and testing the arguments supplied to allowQuery.

Exception	`AllowQueryArguments`	Contains positional and keyword arguments in `args`.
Method	`allowQuery`	Raise the arguments supplied to `allowQuery`.

Inherited from DNSServerFactory:

Method	`__init__`	No summary
Method	`buildProtocol`	Create an instance of a subclass of Protocol.
Method	`connectionLost`	Stop tracking a no-longer connected `DNSProtocol`.
Method	`connectionMade`	Track a newly connected `DNSProtocol`.
Method	`gotResolverError`	A callback used by `DNSServerFactory.handleQuery` for handling deferred errors from `self.resolver.query`.
Method	`gotResolverResponse`	A callback used by `DNSServerFactory.handleQuery` for handling the deferred response from `self.resolver.query`.
Method	`handleInverseQuery`	Called by `DNSServerFactory.messageReceived` when an inverse query message is received.
Method	`handleNotify`	Called by `DNSServerFactory.messageReceived` when a notify message is received.
Method	`handleOther`	Called by `DNSServerFactory.messageReceived` when a message with unrecognised OPCODE is received.
Method	`handleQuery`	Called by `DNSServerFactory.messageReceived` when a query message is received.
Method	`handleStatus`	Called by `DNSServerFactory.messageReceived` when a status message is received.
Method	`messageReceived`	`DNSServerFactory.messageReceived` is called by protocols which are under the control of this `DNSServerFactory` whenever they receive a DNS query message or an unexpected / duplicate / late DNS response message.
Method	`sendReply`	Send a response `message` to a given `address` via the supplied `protocol`.
Instance Variable	`cache`	A `Cache` instance whose `cacheResult` method is called when a response is received from one of `clients`. Defaults to `None` if no caches are specified. See `caches` of `__init__` for more details.
Instance Variable	`canRecurse`	A flag indicating whether this server is capable of performing recursive DNS resolution.
Instance Variable	`connections`	A list of all the connected `DNSProtocol` instances using this object as their controller.
Instance Variable	`protocol`	A callable used for building a DNS stream protocol. Called by `DNSServerFactory.buildProtocol` and passed the `DNSServerFactory` instance as the one and only positional argument. Defaults to `dns.DNSProtocol`...
Instance Variable	`resolver`	A `resolve.ResolverChain` containing an ordered list of `authorities`, `caches` and `clients` to which queries will be dispatched.
Instance Variable	`verbose`	See `__init__`
Method	`_responseFromMessage`	Generate a `Message` instance suitable for use as the response to `message`.
Method	`_verboseLog`	Log a message only if verbose logging is enabled.
Instance Variable	`_messageFactory`	A response message constructor with an initializer signature matching `dns.Message.__init__`.

Inherited from Factory (via DNSServerFactory, ServerFactory):

Class Method	`forProtocol`	Create a factory for the given protocol.
Method	`doStart`	Make sure startFactory is called.
Method	`doStop`	Make sure stopFactory is called.
Method	`logPrefix`	Describe this factory for log messages.
Method	`startFactory`	This will be called before I begin listening on a Port or Connector.
Method	`stopFactory`	This will be called before I stop listening on all Ports/Connectors.
Class Variable	`noisy`	Undocumented
Instance Variable	`numPorts`	Undocumented

def allowQuery(self, *args, **kwargs): (source) ¶

overrides twisted.names.server.DNSServerFactory.allowQuery
