Added basic preprocessor class.

import threading

import time

from config import Config

from job_queue import JobQueue

from store_preprocessor import StorePreprocessor

class Preprocessor(threading.Thread):

    def __init__(self):

        threading.Thread.__init__(self)

        config = Config("vos_ts.conf")

        self.params = config.loadSection("scheduling")

        self.maxPendingJobs = self.params.getint("max_pending_jobs")

        self.maxReadyJobs = self.params.getint("max_ready_jobs")

        self.pendingQueue = JobQueue("pending")

        self.readyQueue = JobQueue("ready")

        self.storePreprocessor = StorePreprocessor()

    def run(self):

        while True:

            if(self.readyQueue.len() <= self.maxReadyJobs and self.pendingQueue.len() > 0):

                jobObj = self.pendingQueue.getJob()

                self.storePreprocessor.prepare(jobObj["jobInfo"]["userName"])

                self.storePreprocessor.start()

                self.pendingQueue.moveJobTo("ready")

                print("Job MOVED:")

            time.sleep(1)

# Test

#p = Preprocessor()

#p.start()
