def run(task):
'''
Given a task description, starts the application, waits for the node to stop
running or for the duration to lapse. Stops the application after the execution.
Can be used standalone or with the run_parallel helper.
Example:
>>> task = {
>>> 'app_filename' : 'packages/detect_net/apps/apriltags_process.app.json',
>>> 'more_json' : {
>>> "config": {
>>> "replay.interface": {"output": {"cask_directory": root}},
>>> "record.interface": {"input": {"base_directory": apriltags_root}}
>>> }
>>> },
>>> 'success_node': "replay.interface",
>>> 'duration': 2040.0, 'poll_interval': 1.0, 'exit_interval': 1.0
>>> }
>>>
>>> run(task)
Args:
task['app_filename'] (str): the main application json filename
task['more_json'] (dict): a dictionary containing additional configuration,
to serialize into json and load as more_jsons to the app
task['more_jsons'] (str): a comma-separated string of additional jsons to load
task['name'] (str): the name of the application
task['modules'] (List(str)): a list of modules to be loaded
task['argv']: Command line arguments from sys.argv
task['success_node'] (string): the name of the node to wait to stop running
task['duration'] (float): timeout in seconds, can run forever, if duration is None
task['exit_interval'] (float): exit interval in seconds
Returns: True, if the success status had been reached. False otherwise.
