[Split off from bpo-19395]
The following code hangs after hitting a TypeError trying to pickle one of the TextIOWrapper objects:
import multiprocessing def read(f): return f.read() files = [open(path) for path in 3 * ['/dev/null']] pool = multiprocessing.Pool() results = pool.map(read, files) print(results)
This issue is present in 3.2, 3.3 and 3.4, but not in 2.7.
Sorry, something went wrong.
