Agents for Job Execution and Communication Tasks
================================================

  ($Id$)

  >>> import os
  >>> from time import time

  >>> from cybertools.agent.tests import tester, baseDir
  >>> config = '''
  ... controller(names=['core.sample'])
  ... scheduler(name='core')
  ... logger(name='default', standard=30)
  ... '''
  >>> from cybertools.agent.main import setup
  >>> master = setup(config)
  Starting agent application...
  Using controllers core.sample.


Filesystem Crawler
==================

  >>> controller = master.controllers[0]
  >>> controller.createAgent('crawl.filesystem', 'sample03')

In the next step we request the start of a job, again via the controller.

  >>> path = os.path.join(baseDir, 'testing', 'data')
  >>> controller.enterJob('sample', 'sample03', params=dict(directory=path))

The job is not executed immediately - we have to hand over control to
the twisted reactor first.

  >>> from cybertools.agent.tests import tester
  >>> tester.iterate()
  Job 00001 completed; result: [..., ...];

  >>> r0 = controller.result[0]
  >>> r0.metadata, r0.data
  ({'path': '...file1.txt'}, 'Data from file1.txt')
