# Desynchronized Spider

This abstract class can be extended to produce new plugins that do not require a system-wide configuration synchronization.

## pathspider.desync

class `pathspider.desync.``DesynchronizedSpider`(worker_count, libtrace_uri, args, server_mode=False)
  `configurator`()

    Since there is no need for a configurator thread in a desynchronized spider, this thread is a no-op

  `connections` = []
  classmethod `register_args`(subparsers)
  `worker`(worker_number)

    This function provides the logic for configuration-synchronized worker threads.

    Parameters: | worker_number (int) – The unique number of the worker.

    The workers operate as continuous loops:

    > - Fetch next job from the job queue
    > - Perform pre-connection operations
    > - Acquire a lock for “config_zero”
    > - Perform the “config_zero” connection
    > - Release “config_zero”
    > - Acquire a lock for “config_one”
    > - Perform the “config_one” connection
    > - Release “config_one”
    > - Perform post-connection operations for config_zero and pass the result to the merger
    > - Perform post-connection operations for config_one and pass the result to the merger
    > - Do it all again

    If the job fetched is the SHUTDOWN_SENTINEL, then the worker will terminate as this indicates that all the jobs have now been processed.
