Hi,
we've been asked if Autobahn runs under Jython. Since there is an upcoming Jython version that supports 2.7 Python API, I thought I'd give it a try.
To my astonishment, I was able to get Autobahn working with minor efforts ...
That's very cool. Can you file tickets in the issue tracker and attach patches there? The mailing list is where diffs go to be forgotten. Here's a start: http://twistedmatrix.com/trac/ticket/3413 Jean-Paul
Tested: Twisted 12.3 under Jython from sources (together with zope.interface 4.05 and setuptools from sources) after applying the following patches. Stock AutobahnPython 0.6 from source.
1) Missing __builtin__.buffer
The following is a workaround due to http://bugs.jython.org/issue1521
Include
# workaround for Jython, see: http://bugs.jython.org/issue1521 import __builtin__ if not hasattr(__builtin__, 'buffer'): def _buffer(object, offset = None, size = None): if offset is None: offset = 0 if size is None: size = len(object) return object[offset:offset+size] __builtin__.buffer = _buffer
at the beginning of "twisted/python/compat.py".
2) Weird platform ident
Jython identifies itself as "Java" .. I was testing on Windows.
twisted/python/runtime.py
Line 36
#'java': 'java', 'java': 'win32',
This is necessary on Windows since otherwise Posix API is assumed.
Of course above is just a quick hack.
C:\Users\oberstet>jython Jython 2.7b1 (default:ac42d59644e9, Feb 9 2013, 15:24:52) [Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0 Type "help", "copyright", "credits" or "license" for more information.
import sys, os sys.platform 'java1.7.0' os.name 'java'
IMHO, os.name should return the real underlying OS on Jython, not "java" .. what do you think?
===
Where should those issue be adressed? Should Twisted include workarounds or should I lobby at Jython to "do the right" thing?
Cheers, Tobias
