This abstract class can be extended to produce new plugins that do not require a system-wide configuration synchronization.
DesynchronizedSpider(worker_count, libtrace_uri, args, server_mode=False)¶
Since there is no need for a configurator thread in a desynchronized spider, this thread is a no-op
This function provides the logic for non-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
- For each connection, perform the connection 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.
