t.i.p._BaseProcess(BaseProcess, object) : class documentation

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

Known subclasses: twisted.internet.process.Process, twisted.internet.process.PTYProcess

Base class for Process and PTYProcess.

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	_setupChild	Setup the child process. Override in subclasses.
Method	_execChild	The exec() which is done in the forked child.

Inherited from BaseProcess:

Method	__init__	Undocumented
Method	processEnded	This is called when the child terminates.
Method	maybeCallProcessEnded	Call processEnded on protocol after final cleanup.
Method	_callProcessExited	Undocumented

Inherited from Ephemeral (via BaseProcess):

Method	__getstate__	Undocumented
Method	__setstate__	Undocumented

def reapProcess(self): (source)

Try to reap a process (without blocking) via waitpid.

This is called when sigchild is caught or a Process object loses its "connection" (stdout is closed) This ought to result in reaping all zombie processes, since it will be called twice as often as it needs to be.

(Unfortunately, this is a slightly experimental approach, since UNIX has no way to be really sure that your process is going to go away w/o blocking. I don't want to block.)

def _getReason(self, status): (source)

Undocumented

def signalProcess(self, signalID): (source)

Send the given signal signalID to the process. It'll translate a few signals ('HUP', 'STOP', 'INT', 'KILL', 'TERM') from a string representation to its int value, otherwise it'll pass directly the value provided

def _resetSignalDisposition(self): (source)

Undocumented

def _fork(self, path, uid, gid, executable, args, environment, **kwargs): (source)

Fork and then exec sub-process.

Parameters	path	the path where to run the new process. (type: `str`)
	uid	if defined, the uid used to run the new process. (type: `int`)
	gid	if defined, the gid used to run the new process. (type: `int`)
	executable	the executable to run in a new process. (type: `str`)
	args	arguments used to create the new process. (type: `list`.)
	environment	environment used for the new process. (type: `dict`.)
	kwargs	keyword arguments to `_setupChild` method.

def _setupChild(self, *args, **kwargs): (source)

overridden in twisted.internet.process.Process, twisted.internet.process.PTYProcess

Setup the child process. Override in subclasses.

def _execChild(self, path, settingUID, uid, gid, executable, args, environment): (source)

The exec() which is done in the forked child.

def __repr__(self): (source)

String representation of a process.
