I have been using a custom Qt4 reactor that derives from PosixReactorBase. As a result it creates a _Win32Waker to allow threads and signals to wake up the IO thread. It seems though that the current implementation only works about half of the time. The other half it exists with :
File "...\Lib\python2.6\site-packages\twisted\internet\posixbase.py",
line 170, in __init__
ReactorBase.__init__(self)
File "...\Lib\python2.6\site-packages\twisted\internet\base.py",
line 424, in __init__
self._initThreads()
File "...\Lib\python2.6\site-packages\twisted\internet\base.py",
line 813, in _initThreads
self.installWaker()
File "...\Lib\python2.6\site-packages\twisted\internet\posixbase.py",
line 206, in installWaker
self.waker = _Waker(self)
File "...\Lib\python2.6\site-packages\twisted\internet\posixbase.py",
line 77, in __init__
client.connect(server.getsockname())
File "<string>", line 1, in connect
socket.error: [Errno 10049] The requested address is not valid in its context
I have attached a simple test that shows that the following code does
not always return "127.0.0.1", but sometimes returns "0.0.0.0" as the
IP address.
# Following select_trigger (from asyncore)'s example;
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.setsockopt(socket.IPPROTO_TCP, 1, 1)
server.bind(('127.0.0.1', 0))
server.listen(1)
client.connect(server.getsockname())
My current workaround just calls the following instead:
client.connect(('127.0.0.1', server.getsockname()[1]))
Any ideas on what is really causing the error? If there is not a
better solution can this be added to trunk for future releases?
Thanks,
Aron
