New submission from Zahari Dim: The following example should start two processes, but instead it starts three, even though only two do_work(). A third process is incorrectly started after the first one finishes.
import os import time from multiprocessing import Pool def initprocess(): print("Starting PID: %d" % os.getpid()) def do_work(x): print("Doing work in %d" % os.getpid()) time.sleep(x**2) if __name__ == '__main__': p = Pool(2, initializer=initprocess,maxtasksperchild=1) results = p.map(do_work, (1,2), chunksize=1) ---------- components: Library (Lib) messages: 245878 nosy: Zahari.Dim priority: normal severity: normal status: open title: multiprocessing.Pool with maxtasksperchild starts too many processes type: resource usage versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24519> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
