AutobahnPython on Jython

[Tobias Oberstein]

Hi,

get AutobahnPython running on Jython .. pls see

http://twistedmatrix.com/trac/ticket/3413#comment:21

and the AutobahnPython project's README.

I tested a server using AutobahnTestsuite .. it passes everything
(though a few non-strict cases that are timing/reactor related).

Don't hold your breath .. it's a little slower than CPython.

But running AutobahnPython under Jython might come handy for some
situations ..

Great!, actually this could help me a lot, since I'm trying to avoid the CPython GIL in order to leverage on multiple cores with a heavily threaded environment, and I'm using twisted not only for autobahn but the whole server.

Thanks!.

I'm trying to reproduce your installation, using Jython 2.7b1, and I already did the patches you suggested. But I'm having trouble with other things, I'm getting a module not found:
>>> import twisted
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/twisted/__init__.py", line 53, in <module>
    _checkRequirements()
  File "/usr/local/lib/python2.7/dist-packages/twisted/__init__.py", line 37, in _checkRequirements
    raise ImportError(required + ": no module named zope.interface.")
ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface.

But module is there, zope is installed (right next to twisted in the directory) and its version is 4.0.5.
And I'm able to
Did you had this problem? any Idea on how to fix it?.

And I'm able to import the module zope "isolated".

Just saying, for Autobahn (WAMP or WebSocket) _itself_:

Don't expect any performance gains from Jython (to the contrary). For
example, Jython only exposes Posix select, not epoll or kqueue or IOCP.
If you want performance, try PyPy ..

No, I did not have issues with that. Are you sure you installed Twisted
and zope.interface into the Jython site-packages?

Since above traceback refers to

/usr/local/lib/python2.7/dist-packages/

Yup, you're right, I haven't, I just added the dist-packages of my current python installation to the sys.path in Jython.
I will install it inside Jython instead and try.
