t.i.p.PTYProcess(abstract.FileDescriptor, _BaseProcess) : class documentation

Part of twisted.internet.process View Source View In Hierarchy

Implements interfaces: twisted.internet.interfaces.IProcessTransport

An operating-system Process that uses PTY support.
Method __init__ Spawn an operating-system process.
Method closeStdin Close stdin after all data has been written out.
Method closeStdout Close stdout.
Method closeStderr Close stderr.
Method doRead Called when my standard output stream is ready for reading.
Method fileno This returns the file number of standard output on this process.
Method maybeCallProcessEnded Call processEnded on protocol after final cleanup.
Method connectionLost I call this to clean up when one or all of my connections has died.
Method writeSomeData Write some data to the open process.
Method _setupChild Setup child process after fork() but before exec().

Inherited from FileDescriptor:

Method logPrefix Returns the default log prefix
Method doWrite Called when data can be written.
Method writeConnectionLost Indicates write connection was lost.
Method readConnectionLost Indicates read connection was lost.
Method write Reliably write some data.
Method writeSequence Reliably write a sequence of data.
Method loseConnection Close the connection at the next available opportunity.
Method loseWriteConnection Undocumented
Method stopReading Stop waiting for read availability.
Method stopWriting Stop waiting for write availability.
Method startReading Start waiting for read availability.
Method startWriting Start waiting for write availability.
Method stopConsuming Stop consuming data.
Method resumeProducing Undocumented
Method pauseProducing Undocumented
Method stopProducing Stop producing data.
Method _postLoseConnection Called after a loseConnection(), when all data has been written.
Method _closeWriteConnection Undocumented

Inherited from _ConsumerMixin (via FileDescriptor):

Method registerProducer Register to receive data from a producer.
Method unregisterProducer Stop consuming data from a producer, without disconnecting.

Inherited from _BaseProcess:

Method reapProcess Try to reap a process (without blocking) via waitpid.
Method signalProcess No summary
Method __repr__ String representation of a process.
Method _getReason Undocumented
Method _resetSignalDisposition Undocumented
Method _fork Fork and then exec sub-process.
Method _execChild The exec() which is done in the forked child.

Inherited from BaseProcess (via _BaseProcess):

Method processEnded This is called when the child terminates.
Method _callProcessExited Undocumented

Inherited from Ephemeral (via _BaseProcess, BaseProcess):

Method __getstate__ Undocumented
Method __setstate__ Undocumented
def __init__(self, reactor, executable, args, environment, path, proto, uid=None, gid=None, usePTY=None): (source)

Spawn an operating-system process.

This is where the hard work of disconnecting all currently open files / forking / executing the new process happens. (This is executed automatically when a Process is instantiated.)

This will also run the subprocess as a given user ID and group ID, if specified. (Implementation Note: this doesn't support all the arcane nuances of setXXuid on UNIX: it will assume that either your effective or real UID is 0.)
def _setupChild(self, masterfd, slavefd): (source)
Setup child process after fork() but before exec().
def closeStdin(self): (source)
Close stdin after all data has been written out.
def closeStdout(self): (source)
Close stdout.
def closeStderr(self): (source)
Close stderr.
def doRead(self): (source)
Called when my standard output stream is ready for reading.
def fileno(self): (source)
This returns the file number of standard output on this process.
def maybeCallProcessEnded(self): (source)
Call processEnded on protocol after final cleanup.
def connectionLost(self, reason): (source)
I call this to clean up when one or all of my connections has died.
def writeSomeData(self, data): (source)
Write some data to the open process.
