The following code hangs:
---
import multiprocessing, time
pool = multiprocessing.Pool(1)
result = pool.apply_async(time.sleep, (1.0,))
pool.terminate()
result.get()
---
pool.terminate() terminates workers before time.sleep(1.0) completes, but the pool doesn't mark result as completed with an error.
Would it be possible to mark all pending tasks as failed? For example, "raise" a RuntimeError("pool terminated before task completed").

Attached PR 11139 sets RuntimeError("Pool terminated") error in pending results if the pool is terminated. |

Pablo: since you worked on multiprocessing recently, did you see this bug? I'm not sure about my PR 11139... If someone else wants to work on a fix, ignore my PR ;-) |
