twisted.trial._dist.worker.WorkerProtocol(AMP) class documentation

Method	__init__	Undocumented
Method	run	Run a test case by name.
Method	start	Set up the worker, moving into given directory for tests to run in them.

Inherited from AMP:

Method	locateResponder	Unify the implementations of CommandLocator and SimpleStringLocator to perform both kinds of dispatch, preferring CommandLocator.
Method	__repr__	A verbose string representation which gives us information about this AMP connection.
Method	makeConnection	Emit a helpful log message when the connection is made.
Method	connectionLost	Emit a helpful log message when the connection is lost.

Inherited from BinaryBoxProtocol (via AMP):

Instance Variable	boxReceiver	an IBoxReceiver provider, whose IBoxReceiver.ampBoxReceived method will be invoked for each AmpBox that is received.
Method	sendBox	Send a amp.Box to my peer.
Method	dataReceived	Either parse incoming data as AmpBoxes or relay it to our nested protocol.
Method	proto_init	String received in the 'init' state.
Method	proto_key	String received in the 'key' state. If the key is empty, a complete box has been received.
Method	proto_value	String received in the 'value' state.
Method	lengthLimitExceeded	The key length limit was exceeded. Disconnect the transport and make sure a meaningful exception is reported.
Method	unhandledError	The buck stops here. This error was completely unhandled, time to terminate the connection.
Instance Variable	_keyLengthLimitExceeded	A flag which is only true when the connection is being closed because a key length prefix which was longer than allowed by the protocol was received.
Method	_switchTo	Switch this BinaryBoxProtocol's transport to a new protocol. You need to do this 'simultaneously' on both ends of a connection; the easiest way to do this is to use a subclass of ProtocolSwitchCommand.
Method	_lockForSwitch	No summary
Method	_unlockFromSwitch	Unlock this locked binary protocol so that further boxes may be sent again. This is used after an attempt to switch protocols has failed for some reason.
Method	_prepareTLS	Used by StartTLSCommand to put us into the state where we don't actually send things that get sent, instead we buffer them. see _sendBoxCommand.
Method	_startTLS	Used by TLSBox to initiate the SSL handshake.
Method	_getPeerCertificate	Undocumented
Method	_defaultStartTLSResponder	The default TLS responder doesn't specify any certificate or anything.

Inherited from StatefulStringProtocol (via AMP, BinaryBoxProtocol):

Instance Variable	state	Current state of the protocol. Defaults to 'init'. (type: str)
Method	stringReceived	Choose a protocol phase function and call it.

Inherited from IntNStringReceiver (via AMP, BinaryBoxProtocol, Int16StringReceiver):

Instance Variable	structFormat	format used for struct packing/unpacking. Define it in subclass. (type: str)
Instance Variable	prefixLength	length of the prefix, in bytes. Define it in subclass, using struct.calcsize(structFormat) (type: int)
Method	stringReceived	Override this for notification when each complete string is received.
Method	sendString	Send a prefixed string to the other end of the connection.
Instance Variable	_unprocessed	bytes received, but not yet broken up into messages / sent to stringReceived. _compatibilityOffset must be updated when this value is updated so that the recvd attribute can be generated correctly. (type: bytes)
Instance Variable	_compatibilityOffset	the offset within _unprocessed to the next message to be parsed. (used to generate the recvd attribute) (type: int)

Inherited from Protocol (via AMP, BinaryBoxProtocol, Int16StringReceiver, IntNStringReceiver):

Method

logPrefix

Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via AMP, BinaryBoxProtocol, Int16StringReceiver, IntNStringReceiver, Protocol):

Method

connectionMade

Called when a connection is made.

Inherited from _PauseableMixin (via AMP, BinaryBoxProtocol, Int16StringReceiver, IntNStringReceiver):

Method	pauseProducing	Undocumented
Method	resumeProducing	Undocumented
Method	stopProducing	Undocumented

Inherited from _DescriptorExchanger (via AMP, BinaryBoxProtocol):

Method	fileDescriptorReceived	Collect received file descriptors to be claimed later by Descriptor.
Instance Variable	_descriptors	Temporary storage for all file descriptors received. Values in this dictionary are the file descriptors (as integers). Keys in this dictionary are ordinals giving the order in which each descriptor was received. The ordering information is used to allow Descriptor to determine which is the correct descriptor for any particular usage of that argument type. (type: dict)
Instance Variable	_sendingDescriptorCounter	A no-argument callable which returns the ordinals, starting from 0. This is used to construct values for _sendFileDescriptor.
Instance Variable	_receivingDescriptorCounter	A no-argument callable which returns the ordinals, starting from 0. This is used to construct values for fileDescriptorReceived.
Method	_sendFileDescriptor	Assign and return the next ordinal to the given descriptor after sending the descriptor over this protocol's transport.

Inherited from BoxDispatcher (via AMP):

Instance Variable	locator	an object with a CommandLocator.locateResponder method that locates a responder function that takes a Box and returns a result (either a Box or a Deferred which fires one).
Instance Variable	boxSender	an object which can send boxes, via the _sendBoxCommand method, such as an AMP instance. (type: IBoxSender)
Method	startReceivingBoxes	The given boxSender is going to start calling boxReceived on this BoxDispatcher.
Method	stopReceivingBoxes	No further boxes will be received here. Terminate all currently outstanding command deferreds with the given reason.
Method	failAllOutgoing	Call the errback on all outstanding requests awaiting responses.
Method	callRemoteString	This is a low-level API, designed only for optimizing simple messages for which the overhead of parsing is too great.
Method	callRemote	This is the primary high-level API for sending messages via AMP. Invoke it with a command and appropriate arguments to send a message to this connection's peer.
Method	unhandledError	This is a terminal callback called after application code has had a chance to quash any errors.
Method	ampBoxReceived	An AmpBox was received, representing a command, or an answer to a previously issued command (either successful or erroneous). Respond to it according to its contents.
Method	dispatchCommand	A box with a _command key was received.
Instance Variable	_outstandingRequests	a dictionary mapping request IDs to Deferreds which were returned for those requests.
Method	_nextTag	Generate protocol-local serial numbers for _ask keys.
Method	_sendBoxCommand	Send a command across the wire with the given amp.Box.
Method	_answerReceived	An AMP box was received that answered a command previously sent with callRemote.
Method	_errorReceived	An AMP box was received that answered a command previously sent with callRemote, with an error.
Method	_commandReceived
Method	_safeEmit	Emit a box, ignoring ProtocolSwitched and ConnectionLost errors which cannot be usefully handled.

Inherited from CommandLocator (via AMP):

Class	__metaclass__	No summary
Method	lookupFunction	Deprecated synonym for CommandLocator.locateResponder
Method	_wrapWithSerialization	Wrap aCallable with its command's argument de-serialization and result serialization logic.
