Example server

Sometimes it’s easier to just learn by looking at some sample code, so here is a simple server that demonstrates most of how to use gmtasks.

from multiprocessing   import freeze_support
from gmtasks.jsonclass import GearmanWorker
from gmtasks           import GearmanTaskServer, Task

# Jobs
def job1(worker, job):
    return job.data['string1']
def job2(worker, job):
    return job.data['string2']
def job3(worker, job):
    return job.data['string3']

# Main loop
if __name__ == '__main__':
    # Need this to run in Windows
    freeze_support()
    # Import all of the jobs we handle
    tasks = [
        # You can use a Task()
        Task('job1', job1),
        # Or a dict
        {'task': 'job2', 'callback': job2},
        # Or a list/tuple
        ['job3', job3],
        ]
    # Initialize the server
    server = GearmanTaskServer(
        host_list      = ['localhost:4730'],
        tasks          = tasks,
        max_workers    = None, # Defaults to multiprocessing.cpu_count()
        id_prefix      = 'myworker.',
        worker_class   = GearmanWorker,
        use_sighandler = True, # SIGINT and SIGTERM send KeyboardInterrupt
        verbose        = True, # log.info() and log.error() messages
        )
    # Run the loop
    server.serve_forever()
