Hello group,
I'm pretty despereate right now and apologize for my diffuse question in
advance - but I do not know how to continue right now.
I'm writing a GUI client (pygtk) which talks to a server (TCP/IP),
fetches pictures (FITS format) and displays them. This works nicely.
Now I have a plugin which is called from a menu. The plugin also talks
to the server, then fetches a picture. However, when trying to fetch a
picture this way, the Python program hangs - every time, always at the
same position - and I have not the least clue why.
File "./guiclient.py", line 368, in on_Focus
self.__plugin_instances[0].run()
File "plugins/Focus.py", line 57, in run
img = result.fetch()
File "/home/joe/client/imgproto/Connection.py", line 54, in fetch
return self.__device.conn().getbindata()
File "/home/joe/client/imgproto/TransportLayerConnection.py", line
100, in getbindata
copied = self.__s.recv_into(result[pos:], remaining)
The debug output of my program indicates that *always* the last 1023
bytes are waited for. Wireshark however tells me they are sent!
Done, fetching '2009_06_15_11_12_12_picture'

I then tried to multithread that, which did not work either (showed even
more confusing behaviour). What in the world could possibly cause such
an error? How can I trace it?
Kind regards,
Johannes
