Problem with the ipy.vim script

I'm trying to use the ipy.vim script to set up a small python dev environment, but I'm running into a connection problem. When I type ipy_vimserver.setup("demo") I get this error:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner
    self.run()
  File "/usr/lib/pymodules/python2.6/IPython/Extensions/ipy_vimserver.py", line 109, in ser开发者_如何学编程ve_me
    self.listen()
  File "/usr/lib/pymodules/python2.6/IPython/Extensions/ipy_vimserver.py", line 93, in listen
    self.socket.bind(self.__sname)
  File "<string>", line 1, in bind
error: [Errno 98] Address already in use

When I type it a second time, everything is fine but when I launch gvim the F4/F5 command do nothing and state that they can't connect to the Ipython server.

any suggestion?

Problem:

Look at the last line of the stack trace: error: [Errno 98] Address already in use

Explanation:

A nice explanation of "Address already in use" error can be found here: "Bind: Address Already in Use"

Possible Solution:

As I have not tried ipy.vim setup myself, from networking point of view, a quick suggestion would be to:

• close/kill both the server (ipython server) and the client (vim running ipy.vim).
• Restart ipython server
• Run vim with ipy.vim and try to debug.

Additional Info:

• On Linux/Unix machines, the timeout values are defined in /proc/sys/net/ipv4/tcp_keepalive_time and /proc/sys/net/ipv4/tcp_fin_time
• On Windows machines, this is set in HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpTimedWaitDelay. More details is here: TcpTimedWaitDelay

If I run the exact same code I get the same error. If I change the name from "demo" to, for example, "cookies" it works. Hmm....

This happens when there's already a socket with the name you're trying to create, in this case 'demo'. You need to delete it before doing the ipy_vimserver.setup - in your case, the socket file to delete is ~/.ipython/demo
