Hi,
very good point, I've been on beta3. But the upgrade didn't help. I've
figured out how to debug the internals in VS, but there's nothing I could
be able to fix (or even understand) myself at this point.
ad 1) after running wdb.server, Tornado at first says
\tornado\netutil.py", line 88, in bind_sockets
AttributeError: 'module' object has no attribute 'IPV6_V6ONLY'
When I comment the whole if section out, it starts the loop and waits for
connections.
Running the client, the server reports this and continues listening:
Connection received from ('127.0.0.1', 1518)
[E 141125 11:51:35 stack_context:1] Exception in I/O handler for fd 1616
Traceback (most recent call last):
File "-\tornado\stack_context.py", line 304, in wrapped
ret = fn(*args, **kwargs)
File "-\tornado\netutil.py", line 154, in accept_handler
callback(connection, address)
File "-\wdb_server\streams.py", line 95, in handle_connection
stream.read_bytes(4, partial(read_uuid_size, stream))
File "-\tornado\iostream.py", line 168, in read_bytes
self._try_inline_read()
File "-\tornado\iostream.py", line 424, in _try_inline_read
if self._read_to_buffer() == 0:
File "-\tornado\iostream.py", line 447, in _read_to_buffer
chunk = self.read_from_fd()
File "-\tornado\iostream.py", line 686, in read_from_fd
chunk = self.socket.recv(self.read_chunk_size)
error: [Errno 10022] A request to send or receive data was disallowed
because the socket is not connected and (when sending on a datagram socket
using a sendto call) no address was supplied
And the client crashes with
wdb\client\wdb\_compat.py", line 165, in send_bytes
socket.error: [Errno 10053] An established connection was aborted by the
software in your host machine
When trying to debug this in VS, I came to the conclusion that the Tornado
server's socket handling (or my commenting out a piece, or something else
inside Tornado running under IronPython-) is at fault, since it's not true
what I've written previously (that a message gets communicated and then
coms fail) - in fact nothing gets communicated, it crashes in the client on
trying to send the first message using socket.cs sendallWorker(byte[]
buffer, int flags).
ad 2) running the server in Python and client in IronPython, I get a bit
further, but the error is the same - the client in IronPython reports
Launching browser and wait for connection
Exception Traceback (most recent call last):
File "-\wdb\client\wdb\__init__.py", line 291, in trace_debug_dispatch
File "-\wdb\client\wdb\__init__.py", line 250, in trace_dispatch
File "-\wdb\client\wdb\__init__.py", line 686, in handle_call
File "-\wdb\client\wdb\__init__.py", line 660, in interaction
File "-\wdb\client\wdb\ui.py", line 80, in __init__
File "-\wdb\client\wdb\__init__.py", line 575, in get_trace
TypeError: Unable to cast object of type
'System.Linq.Expressions.FieldExpression' to type
'System.Linq.Expressions.BlockExpression'.
It's the same place and line of code I mentioned in my previous mail:
> startlnos = dis.findlinestarts(code)
Debugging in VS yields an impressive stack trace, but I don't have any idea
where to start with this, so again - I'll be very grateful for any pointers.
Thanks - for even reading this far.
