Double close of FD 0 when child process spawns its own child process. Bug causes wrong file descriptors to be closed. Bug affects only posix system. How to reproduce: >>> import multiprocessing as mp >>> def child(q): ... print 'current process:', mp.current_process().name ... q.put(1) ... q.get() ... p = mp.Process(None, child, args=(mp.Queue(),)) ... p.start() ... >>> q = mp.Queue() >>> child(q) current process: MainProcess current process: Process-1 current process: Process-1:1 Process Process-1:1: Traceback (most recent call last): File "/usr/lib/python2.5/site-packages/multiprocessing/process.py", line 236, in _bootstrap self.run() File "/usr/lib/python2.5/site-packages/multiprocessing/process.py", line 93, in run self._target(*self._args, **self._kwargs) File "<stdin>", line 4, in child File "/usr/lib/python2.5/site-packages/multiprocessing/queues.py", line 91, in get res = self._recv() IOError: [Errno 9] Bad file descriptor |
