Undocumented
def _attachLog(self, logger):
Undocumented
def test_timeout_long(self):
When a job exceeds its lease, an exception is raised.

Unfortunately, timeouts include the time it takes for the zope machinery to start up, so we run a job that will not time out first, followed by a job that is sure to time out.

def disabled_test_timeout_short(self):
When a job exceeds its lease, an exception is raised.

Unfortunately, timeouts include the time it takes for the zope machinery to start up, so we run a job that will not time out first, followed by a job that is sure to time out.

def test_previous_failure_gives_new_process(self):
Failed jobs cause their worker to be terminated.

When a job fails, it's not clear whether its process can be safely reused for a new job, so we kill the worker.

def test_successful_jobs_share_process(self):
Successful jobs allow process reuse.

When a job succeeds, we assume that its process can be safely reused for a new job, so we reuse the worker.

def disable_test_memory_hog_job(self):
A job with a memory limit will trigger MemoryError on excess.
def test_no_jobs(self):
Undocumented
def test_lease_held_handled(self):
Jobs that raise LeaseHeld are handled correctly.
