New submission from John Brearley:
Using a multiprocessing.connection listener, I can accept an incoming socket
OK, but when I do conn.recv(), I get memory error. The attached script
mpl_bug.py will readily reproduce the issues on WinXP & WinVista, see sample
output below:
<pre>
c:\>python mpl_bug.py
main server listening on host port 10500
main created simple_client <Process(Process-1, initial)>
simple_client connecting to host localhost port 10500
main conn: <multiprocessing.connection.Connection object at 0x00C94B50> waiting
for data
simple_client sending: b'abcd'
simple_client waiting for data
Traceback (most recent call last):
File "mpl_bug.py", line 61, in <module>
data=conn.recv() ;# Memory Error occurs here <<<==========================
======================
File "c:\python33\lib\multiprocessing\connection.py", line 251, in recv
buf = self._recv_bytes()
File "c:\python33\lib\multiprocessing\connection.py", line 405, in _recv_bytes
return self._recv(size)
File "c:\python33\lib\multiprocessing\connection.py", line 380, in _recv
chunk = read(handle, remaining)
MemoryError
