import datetime/traceback missing in database.py

[chandanahs]

run function of class DatabaseServer, uses traceback & datetime but not imported in the beginning.

the exception block hits only if database server starting fails, and if this is not fixed the re-try of starting database server will not be executed.

Adding below helps:

import traceback
import datetime

run function:(datetime.datetime.utcnow().strftime('%Y-%m-%dT%H:%M:%SZ')))

try:
        self.server.serve_forever()
      except:
        traceback.print_exc()
        logging.error('HTTPServer %s at %s died on %s, restarting...',
                      self.name, self.address,
                      datetime.datetime.utcnow().strftime('%Y-%m-%dT%H:%M:%SZ'))
    logging.info('Shutting down Database Server:%s at %s', self.name,
self.address)
