[issue21998] asyncio: support fork

Zac Medico <zmed...@gentoo.org> added the comment: I'm not sure about possible use cases that might conflict with this approach, but using a separate event loop for each pid seems very reasonable to me, as follows: _default_policy = asyncio.get_event_loop_policy() _pid_loop = {}

[issue29373] subprocess.Popen os.close(p2cread) in _execute_child can cause garbage collection of self.stdout to close a reused file descriptor

Zac Medico added the comment: Actually, os.close(p2cread) closes a different file descriptor than c2pread, so my analysis is not correct. I don't know the precise cause of the EBADF error that I have observed. I suppose it could be some other code closing a file descriptor that belongs

[issue29373] subprocess.Popen os.close(p2cread) in _execute_child can cause garbage collection of self.stdout to close a reused file descriptor

New submission from Zac Medico: In Popen _execute_child method, os.close(p2cread) closes a file descriptor which is referenced by self.stdout with closefd=True, created by this code: self.stdout = io.open(c2pread, 'rb', bufsize) When self.stdout is finally garbage collected, it can close

[issue5380] pty.read raises IOError when slave pty device is closed

Zac Medico zmed...@gentoo.org added the comment: This issue no longer appears to be a problem for my purposes, since it seems that array.fromfile() does not lose any data as long as the input file is opened in unbuffered mode (I use fdopen with 0 for the bufsize argument

[issue5380] array.fromfile() on master pty raises IOError when slave pty device is closed

New submission from Zac Medico zmed...@gentoo.org: With python-3.0, array.fromfile() raises an IOError when reading from a master pty device after the slave device has been closed. This causes remaining data that had been written to the slave device to be lost. I have observed this problem

[issue5334] array.fromfile() fails to insert values when EOFError is raised

New submission from Zac Medico zmed...@gentoo.org: With python-3.0, array.fromfile() fails to insert values when EOFError is raised. I ran the attached test case with python-3.0.1 and got the same result on both linux and windows. With python-2.x, the values are properly inserted despite
