There was this failure on one of the XP buildbots: Process Process-269: Traceback (most recent call last): File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\process.py", line 258, in _bootstrap self.run() File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\process.py", line 95, in run self._target(*self._args, **self._kwargs) File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\test\test_multiprocessing.py", line 1980, in _listener new_conn = l.accept() File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\connection.py", line 444, in accept c = self._listener.accept() File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\connection.py", line 624, in accept ov = _winapi.ConnectNamedPipe(handle, overlapped=True) BrokenPipeError: [Error 232] The pipe is being closed ====================================================================== ERROR: test_pickling (test.test_multiprocessing.WithProcessesTestPicklingConnections) ---------------------------------------------------------------------- Traceback (most recent call last): File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\connection.py", line 308, in _recv_bytes nread, err = ov.GetOverlappedResult(True) BrokenPipeError: [Error 109] The pipe has been ended During handling of the above exception, another exception occurred: Traceback (most recent call last): File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\test\test_multiprocessing.py", line 2030, in test_pickling new_conn = lconn.recv() File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\connection.py", line 252, in recv buf = self._recv_bytes() File "D:\cygwin\home\db3l\buildarea\3.x.bolen-windows\build\lib\multiprocessing\connection.py", line 317, in _recv_bytes raise EOFError EOFError (http://www.python.org/dev/buildbot/all/builders/x86%20XP-4%203.x/builds/6534/steps/test/logs/stdio) |

The documentation page for ConnectNamedPipe (http://msdn.microsoft.com/en-us/library/windows/desktop/aa365146(v=vs.85).aspx) has a "community addition" which says that ConnectNamedPipe will appear to fail with ERROR_NO_DATA (232) if a client has previously connected, written some data and disconnected. That seems to be what is happening. For example Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import multiprocessing.connection as con >>> l = con.Listener() >>> c = con.Client(l.address) >>> c.send("hello") >>> c.close() >>> l.accept() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "c:\Python27\lib\multiprocessing\connection.py", line 145, in accept c = self._listener.accept() File "c:\Python27\lib\multiprocessing\connection.py", line 345, in accept win32.ConnectNamedPipe(handle, win32.NULL) WindowsError: [Error 232] The pipe is being closed I will look in to it. The community addition says to just treat ERROR_NO_DATA as success. |
