getSubprocessArgs(self, port)

source code

Get the arguments to start the child python process.

Parameters:

port (int) - the port on which the PyCmdDispatcher's backchannel instance is listening, usually passed as a parameter to the child_bootstrapper.py script which starts up the pyCmdExecutor inside child process started by the PyCmdDispatcher

Returns: tuple ([childArgs], [pyInitCmds])

Return a tuple of a list of args to start the python interpreter, and a list of python commands to initialize the python working environment.

Raises:

NotImplementedError - Raised when this method is not overridden in a derived class.

Overrides: qb.backend.pythonChildBackEnd.PythonChildBackEnd.getSubprocessArgs

generateChildBootstrapper(self, port)

source code

This is only overridden if a 3rd-party application which will be started cannot use the standard child_bootstrapper.py script. This can happen if the 3rd-party app doesn't support passing arguments to the bootstrapper.

Parameters:

port (int) - the port on which the PyCmdDispatcher's backchannel instance is listening, usually passed as a parameter to the child_bootstrapper.py script which starts up the pyCmdExecutor inside child process started by the PyCmdDispatcher

Returns: str

Return the path to the newly-created file
