RF: Create a random socket location for every instance.

[arokem]

See #168

[arokem]

This is not implemented for windows, for now, since that takes a slightly different path (using TCP). I'd be happy for input on how this would work on Windows

@arokem, we could use this on Windows: socket.bind_to_random_port(tcp_addr)

[arokem]

Something like this?

Yup.

[arokem]

Can someone please try this out on a Windows machine to see it doesn't break anything?

[arokem]

Hey @auneri - you are working on a Windows machine, right? Could you please pull from this branch and test that it works for you? I don't have a Windows machine to test on.

Sorry for the delayed response, I'll test this today, will let you know how it goes.

[arokem]

Thanks! Let me know what you find. I do want to put out a new release next
week.

I tried testing this, unfortunatelly I am getting an error. 😢

This is what I get in matlab window:

Error using messenger
Socket creation failed.
Error in matlabserver (line 7)
messenger('init', socket_address); 

and in python:

Starting MATLAB on ZMQ socket tcp://127.0.0.1
Send 'exit' command to kill the server
............................................................MATLAB session timed out after 60 seconds
---------------------------------------------------------------------------

      1 # start matlab session
      2 mlab = Matlab()
----> 3 mlab.start()

D:\Python\Anaconda\lib\site-packages\pymatbridge\pymatbridge.pyc in start(self)
    221             return self
    222         else:
--> 223             raise ValueError("%s failed to start" % self._program_name())
    224 
    225     def _response(self, **kwargs):

ValueError: MATLAB failed to start

After applying the two fixes below I confirmed this fixes #168.

1. Need to call self.socket.unbind(self.socket_addr) after appending port to socket_addr here.
2. Call to _Session._runserver here needs to come after call to socket.unbind.

Thanks @auneri - just making sure - this now works well for you on Windows? Ready to merge?

[auneri]

Yes, good to go.
