示例1: Scheduler
# 需要导入模块: from config import Configuration [as 别名]
# 或者: from config.Configuration import getint [as 别名]
class Scheduler(object):
"""
Class that is scheduling tasks in queue and executing processes. Maximum
count of running processes is given by configuration. Next task is scheduled
in occurence of two types of events:
1. When some process is finished and count of running processes is lower
than maximum.
2. When timeout expires and count of running processes is lower than
maximum. This is useful when user add smaller amount of files than
available count to queue and ran conversion. And then added next files.
In this case scheduler check new files and schedule tasks.
When scheduler is selecting new task from queue, takes top row that is not
marked as running. Then new process is started and task is marked as runnig.
Task is removed from queue and according to status of process added to
tasks_done, tasks_incomplete or tasks_failed after finish of process.
Scheduler supports this operations: start, cancel, pause and resume. They
are propagated to running processes. State of of scheduler could be checked
by this properties: running, paused, cancelled.
