I've updated https://github.com/tavendo/AutobahnPython#python-support
Python 2.6 is not supported using Trollius?
I built Python 2.6 from sources .. but it fails
oberstet@vbox-ubuntu1310:~/scm/trollius$ ~/python269/bin/python
Python 2.6.9 (unknown, Jan 8 2014, 11:31:08)
[GCC 4.8.1] on linux3
Type "help", "copyright", "credits" or "license" for more information.

I don't have the time to patch Py 2.6 to build on a recent host with
OpenSSL 1.0, which seems to require multiple steps:

Is SSL a strict requirement of Trollius?
Here is PyPy3 (which is tracking Python 3.2.3):
(...)
File "setup.py", line 35, in <module>
if sys.version < (2, 7):
TypeError: unorderable types: str < tuple
Oops, it's a typo. Fixed.
Autobahn/Trollius now works on:
oberstet@vbox-ubuntu1310:~/scm/AutobahnPython/examples/asyncio/websocket/echo$
~/pypy3-2.1-beta1-linux64/bin/pypy -V
Python 3.2.3 (d63636b30cc0, Jul 30 2013, 07:02:17)
[PyPy 2.1.0-beta1 with GCC 4.6.3]
The only remaining issue with Autobahn is the use of u"" literals
oberstet@vbox-ubuntu1310:~/scm/AutobahnPython/examples/asyncio/websocket/echo$
~/pypy3-2.1-beta1-linux64/bin/pypy
Python 3.2.3 (d63636b30cc0, Jul 30 2013, 07:02:17)

And now for something completely different: ``the future has just begun''
>>>> s = u"kjshdf"
File "<stdin>", line 1
s = u"kjshdf"
^
SyntaxError: invalid syntax

I thought the 'u' would just be ignored on Py 3 (any version)?
(It works also on Python 3.3 and 3.4.)
Ok, but I guess there is no real reason to use Trollius on those, right?
Using "yield from" in Python 2 raises a SyntaxError. It's not so easy
to write a same code base for Trollius and Tulip. Supporting Python
3.3+ allows to:
(a) port a Python 2 project on Trollius,
(b) port it on Python 3,
(c) and later replace easily Trollius with Tulip.
Makes sense.
For a huge project like OpenStack (+2.5 millions line of Python code!)
it's not posible to do the 3 steps at once. Changes must be
incremental and small.
That's huge. I didn't expect OpenStack being such large;)
