Hi, hope this is the right group for this:I miss two basic (IMO) features in parallel processing: 1. make `threading.Thread.start()` return `self` I'd like to be able to `workers = [Thread(params).start() for params in whatever]`. Right now, it's 5 ugly, menial lines: workers = [] for params in whatever: thread = threading.Thread(params) thread.start() workers.append(thread)
Ugly, menial lines are a clue that a function to hide it could be useful.
2. make multiprocessing pools (incl. ThreadPool) limit the size of their internal queues As it is now, the queue will greedily consume its entire input, and if the input is large and the pool workers are slow in consuming it, this blows up RAM. I'd like to be able to `pool = Pool(4, max_qsize=1000)`. Same with the output queue (finished tasks).
Have you verified that this is a problem in Python?
Or does anyone know of a way to achieve this?
You could try subclassing. -- ~Ethan~ -- https://mail.python.org/mailman/listinfo/python-list
