t.i.s.SelectReactor(posixbase.PosixReactorBase, _extraBase) : class documentation

Known subclasses: twisted.internet._glibbase.PortableGlibReactorBase, twisted.internet.gtkreactor.PortableGtkReactor

Implements interfaces: twisted.internet.interfaces.IReactorFDSet

A select() based reactor - runs on all POSIX platforms and on Win32.

Method	__init__	Initialize file descriptor tracking dictionaries and the base class.
Method	doSelect	Run one iteration of the I/O monitor loop.
Method	addReader	Add a FileDescriptor for notification of data available to read.
Method	addWriter	Add a FileDescriptor for notification of data available to write.
Method	removeReader	Remove a Selectable for notification of data available to read.
Method	removeWriter	Remove a Selectable for notification of data available to write.
Method	removeAll	Remove all readers and writers.
Method	getReaders	Return the list of file descriptors currently monitored for input events by the reactor.
Method	getWriters	Return the list file descriptors currently monitored for output events by the reactor.
Instance Variable	_reads	A dictionary mapping FileDescriptor instances to arbitrary values (this is essentially a set). Keys in this dictionary will be checked for read events.
Instance Variable	_writes	A dictionary mapping FileDescriptor instances to arbitrary values (this is essentially a set). Keys in this dictionary will be checked for writability.
Method	_preenDescriptors	Undocumented
Method	_doReadOrWrite	Undocumented

Inherited from PosixReactorBase:

Method	installWaker	Install a `waker' to allow threads and signals to wake up the IO thread.
Method	spawnProcess	Spawn a process, with a process protocol.
Method	listenUDP	Connects a given DatagramProtocol to the given numeric UDP port.
Method	listenMulticast	Connects a given DatagramProtocol to the given numeric UDP port.
Method	connectUNIX
Method	listenUNIX
Method	listenUNIXDatagram	Connects a given DatagramProtocol to the given path.
Method	connectUNIXDatagram	Connects a ConnectedDatagramProtocol instance to a path.
Method	adoptStreamPort	Create a new IListeningPort from an already-initialized socket.
Method	adoptStreamConnection
Method	listenTCP
Method	connectTCP
Method	connectSSL
Method	listenSSL
Instance Variable	_childWaker	None or a reference to the _SIGCHLDWaker which is used to properly notice child process termination.
Method	_handleSignals	Extend the basic signal handling logic to also support handling SIGCHLD to know when to try to reap child processes.
Method	_uninstallHandler	If a child waker was created and installed, uninstall it now.
Method	_removeAll	Remove all readers and writers, and list of removed IReadDescriptors and IWriteDescriptors.

Inherited from _SignalReactorMixin (via PosixReactorBase):

Method	startRunning	Extend the base implementation in order to remember whether signal handlers should be installed later.
Method	run	Undocumented
Method	mainLoop	Undocumented
Instance Variable	_installSignalHandlers	A flag which indicates whether any signal handlers will be installed during startup. This includes handlers for SIGCHLD to monitor child processes, and SIGINT, SIGTERM, and SIGBREAK to stop the reactor. (type: bool)
Method	_reallyStartRunning	Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.

Inherited from _DisconnectSelectableMixin (via PosixReactorBase):

Method

_disconnectSelectable

Utility function for disconnecting a selectable.

Inherited from ReactorBase (via PosixReactorBase):

Instance Variable	running	See IReactorCore.running
Method	installResolver	Set the internal resolver to use to for name lookups.
Method	wakeUp	Wake up the event loop.
Method	doIteration	Do one iteration over the readers and writers which have been added.
Method	resolve	Return a Deferred that will resolve a hostname.
Method	stop	See twisted.internet.interfaces.IReactorCore.stop.
Method	crash	See twisted.internet.interfaces.IReactorCore.crash.
Method	sigInt	Handle a SIGINT interrupt.
Method	sigBreak	Handle a SIGBREAK interrupt.
Method	sigTerm	Handle a SIGTERM interrupt.
Method	disconnectAll	Disconnect every reader, and writer in the system.
Method	iterate	See twisted.internet.interfaces.IReactorCore.iterate.
Method	fireSystemEvent	See twisted.internet.interfaces.IReactorCore.fireSystemEvent.
Method	addSystemEventTrigger	See twisted.internet.interfaces.IReactorCore.addSystemEventTrigger.
Method	removeSystemEventTrigger	See twisted.internet.interfaces.IReactorCore.removeSystemEventTrigger.
Method	callWhenRunning	See twisted.internet.interfaces.IReactorCore.callWhenRunning.
Method	startRunning	Method called when reactor starts: do some initialization and fire startup events.
Method	callLater	See twisted.internet.interfaces.IReactorTime.callLater.
Method	getDelayedCalls	No summary
Method	timeout	Determine the longest time the reactor may sleep (waiting on I/O notification, perhaps) before it must wake up to service a time-related event.
Method	runUntilCurrent	Run all pending timed calls.
Method	callFromThread 0	See twisted.internet.interfaces.IReactorThreads.callFromThread.
Method	getThreadPool	See twisted.internet.interfaces.IReactorThreads.getThreadPool.
Method	callInThread	See twisted.internet.interfaces.IReactorThreads.callInThread.
Method	suggestThreadPoolSize	See twisted.internet.interfaces.IReactorThreads.suggestThreadPoolSize.
Method	callFromThread	Cause a function to be executed by the reactor thread.
Instance Variable	_stopped	A flag which is true between paired calls to reactor.run and reactor.stop. This should be replaced with an explicit state machine. (type: bool)
Instance Variable	_justStopped	A flag which is true between the time reactor.stop is called and the time the shutdown system event is fired. This is used to determine whether that event should be fired after each iteration through the mainloop. This should be replaced with an explicit state machine. (type: bool)
Instance Variable	_started	A flag which is true from the time reactor.run is called until the time reactor.run returns. This is used to prevent calls to reactor.run on a running reactor. This should be replaced with an explicit state machine. (type: bool)
Instance Variable	_registerAsIOThread	A flag controlling whether the reactor will register the thread it is running in as the I/O thread when it starts. If True, registration will be done, otherwise it will not be.
Method	_reallyStartRunning	Method called to transition to the running state. This should happen in the during startup event trigger phase.
Method	_moveCallLaterSooner	Undocumented
Method	_cancelCallLater	Undocumented
Method	_insertNewDelayedCalls	Undocumented
Method	_checkProcessArgs	Check for valid arguments and environment to spawnProcess.
Method	_initThreads	Undocumented
Method	_initThreadPool	Create the threadpool accessible with callFromThread.
Method	_stopThreadPool	No summary

Inherited from _ThreadedWin32EventsMixin:

Method	addEvent
Method	removeEvent
Instance Variable	_reactor	The Win32Reactor running in the other thread. This is None until it is actually needed.
Instance Variable	_reactorThread	The threading.Thread which is running the Win32Reactor. This is None until it is actually needed.
Method	_unmakeHelperReactor	Stop and discard the reactor started by _makeHelperReactor.
Method	_makeHelperReactor	Create and (in a new thread) start a Win32Reactor instance to use for the implementation of IReactorWin32Events.
