class ReconnectingClientFactory(ClientFactory): (source)

Known subclasses: twisted.words.xish.xmlstream.XmlStreamFactory

View In Hierarchy

Factory which auto-reconnects clients with an exponential back-off.

Note that clients should call my resetDelay method after they have connected successfully.

Method __getstate__ Remove all of the state which is mutated by connection attempts and failures, returning just the state which describes how reconnections should be attempted. This will make the unserialized instance behave just as this one did when it was first instantiated.
Method clientConnectionFailed Called when a connection has failed to connect.
Method clientConnectionLost Called when an established connection is lost.
Method resetDelay Call this method after a successful connection: it resets the delay and the retry counter.
Method retry Have this connector connect again, after a suitable delay.
Method stopTrying Put a stop to any attempt to reconnect in progress.
Instance Variable clock The clock used to schedule reconnection. It's mainly useful to be parametrized in tests. If the factory is serialized, this attribute will not be serialized, and the default value (the reactor) will be restored when deserialized.
Instance Variable connector Undocumented
Instance Variable continueTrying Undocumented
Instance Variable delay Undocumented
Instance Variable factor A multiplicitive factor by which the delay grows
Instance Variable initialDelay Delay for the first reconnection attempt.
Instance Variable jitter Percentage of randomness to introduce into the delay length to prevent stampeding.
Instance Variable maxDelay Maximum number of seconds between connection attempts.
Instance Variable maxRetries Maximum number of consecutive unsuccessful connection attempts, after which no further connection attempts will be made. If this is not explicitly set, no maximum is applied.
Instance Variable retries Undocumented
Instance Variable _callID Undocumented

Inherited from ClientFactory:

Method startedConnecting Called when a connection has been started.

Inherited from Factory (via ClientFactory):

Class Method forProtocol Create a factory for the given protocol.
Method buildProtocol Create an instance of a subclass of 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
Class Variable protocol Undocumented
Instance Variable numPorts Undocumented
def __getstate__(self): (source)

Remove all of the state which is mutated by connection attempts and failures, returning just the state which describes how reconnections should be attempted. This will make the unserialized instance behave just as this one did when it was first instantiated.

def clientConnectionFailed(self, connector, reason): (source)

Called when a connection has failed to connect.

It may be useful to call connector.connect() - this will reconnect.

Parameters
connectorUndocumented
reason:twisted.python.failure.FailureUndocumented
def clientConnectionLost(self, connector, unused_reason): (source)

Called when an established connection is lost.

It may be useful to call connector.connect() - this will reconnect.

Parameters
connectorUndocumented
unused_reasonUndocumented
reason:twisted.python.failure.FailureUndocumented
def resetDelay(self): (source)

Call this method after a successful connection: it resets the delay and the retry counter.

def retry(self, connector=None): (source)

Have this connector connect again, after a suitable delay.

def stopTrying(self): (source)

Put a stop to any attempt to reconnect in progress.

The clock used to schedule reconnection. It's mainly useful to be parametrized in tests. If the factory is serialized, this attribute will not be serialized, and the default value (the reactor) will be restored when deserialized.
