There are some other tickets which imply this as a goal, but it hasn't been made explicit that this is desired.

This ticket should be closed when we have a jython buildbot that is green.

A more robust way to work around issue 2) is:

class Platform:
    """Gives us information about the platform we're running on"""

    if os.name == 'java' and hasattr(os, '_name'):
        ## see:
        ## http://bugs.jython.org/issue1521
        ## http://bugs.jython.org/msg7927
        osName = os._name
    else:
        osName = os.name
    type = knownPlatforms.get(osName)

I was able to get Jython 2.7b1 to run Autobahn/Twisted with 2 minor tweaks. I'd like to discuss those tweaks before going through a proper patch/trial/etc cycle ..

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" on any platform. I.e. this is on Windows:

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'

Replace

def isWindows(self):
    if self.getType() == 'java':
        import java.lang.System
        realOs = java.lang.System.getProperty('os.name')
        return realOs.lower().startswith("windows")
    return self.getType() == 'win32'

within "twisted/python/runtime.py".

Any progress here ? I would really love to see this happen and so write a maven plugin that use the autobahntestsuite for running tests again a WebSocket server imll.

All work on this issue is in the branch referenced in the ticket description. As far as getting a slave goes, we still don't have one.

Having been asked, I hereby license the code in my comments above under the MIT license (same as Twisted). Not that I intended anything else anyway ..

I just tried Twisted 13.0 / Jython 2.7b1 (already with above patches).

For whatever reasons I now encountered an additional issue: http://bugs.jython.org/issue2060

Workaround: patch twisted/python/threadable.py for

_dummyID = object()
def getThreadID():
    if threadingmodule is None:
        return _dummyID
    try:
        # workaround for broken Jython
        tid = threadingmodule.currentThread().ident
        return tid
    except AttributeError:
        return _dummyID

#6745 was a duplicate of this.

[twisted-trac]

	tkanerva commented

I attached a set of three patches that should enable twisted.web to serve resources under jython 2.7.

There was some talk on #jython as to how to best check for jython at runtime, and the sys.platform string seems to be the most robust approach.

The implementation of checking thread.ident uses exception catching so that it should have a negligible perf impact on CPython (getting the thread ID is a somewhat common operation under many use cases).

[twisted-trac]

	@oberstet commented

The missing thread ident seems to be fixed http://bugs.jython.org/issue2060 in the upcoming 2.7 release. If the goal is to support Jython >=2.7, then there is no need to work around at least this issue in Twisted ...

Thanks for your patches. I merged this branch forward and applied the first one (jython-lazyByteSlice.diff), although slightly changed due to the merge-forward.

When running trial it dies with this error:

/home/thijs/Downloads/jython2.7b1/bin/jython bin/trial twisted
Traceback (most recent call last):
  File "bin/trial", line 17, in <module>
    from twisted.scripts.trial import run
ImportError: No module named trial

The other 2 patches don't apply cleanly, and I expect they also don't fix this trial issue which is crucial if we want to be able to maintain it. Can you create these patches against the current branch and possibly look into this trial issue and see if you can reproduce it?

[twisted-trac]

	jimbaker commented

The buffer builtin is now available in Jython trunk, as mirrored here - https://bitbucket.org/jython/jython For the moment, we should only be targeting Jython trunk with any Twisted on Jython work - given that we are actively trying to fix Jython for Twisted. With this in place, we can turn to more interesting problems.

To simplify dependency resolution, I'm actually running a slightly different branch, https://bitbucket.org/jimbaker/jython-ssl, which allows for the use of easy_install. (pip requires slightly more work, including presumably a patch to pip, because it does some crazy/illegal/interesting usage of Unicode, so as to detect illegal Unicode.) So to follow along:

in the git clone of Twisted trunk:

~/jython-dev/jython-ssl/dist/bin/easy_install zope.interfaces
~/jython-dev/jython-ssl/dist/bin/jython setup.py install  # develop should also work

With this, I can repeat not being able to get trial running. However, unlike the bug report here, http://bugs.jython.org/issue1956, I do not get java.lang.ArrayIndexOutOfBoundsException:

$ ~/jythondev/jython-ssl/dist/bin/trial twisted
Traceback (most recent call last):
  File "/Users/jbaker/jythondev/jython-ssl/dist/bin/trial", line 8, in <module>
    execfile(__file__)
  File "/Users/jbaker/jythondev/jython-ssl/dist/bin/trial", line 8, in <module>
    execfile(__file__)
  File "/Users/jbaker/opensource/twisted/bin/trial", line 17, in <module>
    from twisted.scripts.trial import run
ImportError: No module named trial

Running from the Jython console gets the same thing:

$ ~/jythondev/jython-ssl/dist/bin/jython
>>> from twisted.scripts import trial
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: cannot import name trial

But twisted.scripts itself is available, along with twisted.trial. So something is not getting setup properly it seems. Maybe there's a platform dispatch that has gone wrong?

Let's turn to that issue. I want something to work, so I tried to use treq:

$ ~/jythondev/jython-ssl/dist/bin/easy_install treq

Then run a simple program, like this one:

from treq import get

def done(response):
    print response.code
    reactor.stop()

get("http://www.github.com").addCallback(done)

from twisted.internet import reactor
reactor.run()

This fails with AttributeError: 'module' object has no attribute 'pipe'

The problem here is that the reactor that's selected assumes full Posix, including os.pipe. However, os.pipe is not available on Jython. So it would seem that the solution that's required here is a reactor specific to Jython, much like has been done for Win32.

It's rather strange that you get an import error for twisted.scripts.trial -- it's simply a normal module that should exist as twisted/scripts/trial.py on your filesystem. Can you verify that it's actually there? If not, there's probably something wrong with the installation process. It'd be helpful to know what twisted.scripts.file and twisted.scripts.path are at run-time, for information-gathering purposes. There shouldn't be anything strange about them, since we don't do any weird hackery or dynamism with the twisted.scripts package.

I investigated this issue further today, and found out the following:

1) twisted/scripts has a non-empty init.py file, which does nontrivial things, and if I modify it to be empty, trial.py and other scripts can be imported.

2) the imports in that init.py themselves aren't probably the culprit, since I can add the imports there and it still works

3) adding the DeprecatedAttribute call from twisted.python.deprecate in init.py seems to be the root cause. I tried to dig deeper into deprecate.py and friends but could not isolate the issue further.

4) despite removing the deprecations from init.py trial still doesn't work properly - it cannot find the plugins necessary for reporter and/or reactor. Doing a --help-reporter gives an empty list, which is odd, since twisted.plugin gets imported correctly (verified that with debug prints).

deprecatedModuleAttribute is definitely doing some pretty severe metaprogramming (expecting to be able to replace the currently-being-imported module object in sys.modules) so that's a good place to begin your investigation.

4) despite removing the deprecations from init.py trial still doesn't work properly - it cannot find the plugins necessary for reporter and/or reactor. Doing a --help-reporter gives an empty list, which is odd, since twisted.plugin gets imported correctly (verified that with debug prints).

Do the tests for twisted.python.modules work on jython?

Replying to glyph:

Signal module derived from one pasted at http://pylonshq.com/pasties/646 - copying it here because pastebins typically aren't permanent.

They added support for signals based on that module: http://bugs.jython.org/issue1074

The builder now fails with: http://buildbot.twistedmatrix.com/builders/ubuntu64-jython2.5-select/builds/102/steps/trial/logs/stdio

so we're one step closer :)

Replying to vschiavoni:

Currently, the build process fails due to a missing dependency toward jruby:

I tried installing twisted 8.2 on the latest jython trunk (r5970) and it works great (no jruby errors here) but getting some UnicodeDecodeError:

byte-compiling build/bdist.java1.5.0_06/egg/twisted/words/test/test_xpath.py to test_xpath$py.class
byte-compiling build/bdist.java1.5.0_06/egg/twisted/words/test/test_domish.py to test_domish$py.class
byte-compiling build/bdist.java1.5.0_06/egg/twisted/words/test/test_jabberxmppstringprep.py to test_jabberxmppstringprep$py.class
Sorry: UnicodeDecodeError: ('unicodeescape', "u'\\udf42'", 2, 9, 'illegal Unicode character')

Opened a Jython ticket for this issue.

(In [26586]) Branching to 'jython-3413'

[twisted-trac]

	@glyph commented

I'm not intending to merge this branch; every fix here should be explained, tested, and merged separately. However, it's easier to smash the fixes together to push Jython as far along as possible to enumerate the other issues. Also, the Jython folks can run tests against this branch and their fix issues in advance of our patches.

Our Jython buildslave is now failing with the following error:

Seems like a Jython issue to me so opened a ticket for them.

fyi, created http://wiki.python.org/jython/TwistedOnJython linking to this ticket.

Thijs: is there a plan to get the buildbot slave back? Progress will stale otherwise.
