Python 3 port is 'done'
Well, done enough to consider merging to master.
While the patch is quite large, most of the changes are simple syntax changes to avoid non-python3 compliant syntax.
The code is available on the kgiusti-python3 branch at the Apache repo.
https://git-wip-us.apache.org/repos/asf?p=qpid-proton.git;a=shortlog;h=refs/heads/kgiusti-python3
I've also made a patch that can be viewed up on reviewboard:
https://reviews.apache.org/r/33691/
I've verified that the unit tests and python examples run under python2.6, 2.7, and python3.3. I'd appreciate if folks would take this patch for a spin and report back their experience.
Known Issues:
These changes will be incompatible with earlier versions of the python 2.x series. I know for a fact that python versions <= 2.4 won't even parse this patch, and I suspect getting such older versions of python to work would require lots of effort. I'm a little unsure of how well python 2.5 will be supported - I have yet to test that far back. I also didn't test anything earlier than 3.3 in the python3.x stream.

Thanks for checking that Chuck. I think I've fixed it - all tests that pass on master now pass for me on the kgiusti-python3 branch under windows.
I see failures of the proton_tests.sasl.* tests on both master and the py3 branch, but I think that may be related by my cyrus setup.

Oops. I missed your reply at the time, just saw it while looking for
something else.
I think we would just switch entirely to Jython 2.7, which has since
reached GA, wouldnt we? Given those bits are only really intended for
use in the tests, I don't see the same need for wide ranging
compatibility there. I also wouldn't expect people to be configuring a
different major version of Jython (but if I were to try, some
incompatibility wouldn't necessarily be that surprising to me
either).

Oops. I missed your reply at the time, just saw it while looking for
something else.
I think we would just switch entirely to Jython 2.7, which has since
reached GA, wouldnt we? Given those bits are only really intended for
use in the tests, I don't see the same need for wide ranging
compatibility there. I also wouldn't expect people to be configuring a
different major version of Jython (but if I were to try, some
incompatibility wouldn't necessarily be that surprising to me
either).

I happened to run into a similar error recently and tracked the issue down.
I believe this error is due to an API incompatibility between jython 2.5
and jython 2.7. In jython 2.5 you need to convert python strings into java
byte arrays manually and you use the 'array' constructor from the jarray
module to do this, e.g. something like:
array("string-that-has-bytes-in-it", 'b') will construct a java byte array
from a python string. In jython 2.7 this conversion is done automatically
(which is nice). Sadly though, the array constructor that worked in jython
2.5 now barfs with exactly the TypeError message you are showing above. I
was able to get a simple smoke test working with proton-j and jython 2.7 by
removing the array constructor and just passing the string directly,
however this will not work on 2.5, so we probably either need to write our
own conversion function that behaves differently for different jython
versions or do a full switch over to 2.7.

I believe this error is due to an API incompatibility between jython 2.5
and jython 2.7. In jython 2.5 you need to convert python strings into java
byte arrays manually and you use the 'array' constructor from the jarray
module to do this, e.g. something like:
array("string-that-has-bytes-in-it", 'b') will construct a java byte array
from a python string. In jython 2.7 this conversion is done automatically
(which is nice). Sadly though, the array constructor that worked in jython
2.5 now barfs with exactly the TypeError message you are showing above. I
was able to get a simple smoke test working with proton-j and jython 2.7 by
removing the array constructor and just passing the string directly,
however this will not work on 2.5, so we probably either need to write our
own conversion function that behaves differently for different jython
versions or do a full switch over to 2.7.

Lots of the tests fail due to error, most if not all of which seem to
be "TypeError: Type not compatible with array". As I say though, this
isnt to do with your changes since it did that last time I tried too
:)
If you want to try it, below is change needed. Probably worth making
sure you clean out the old .pyc files left by previous test runs (I
use git-clean to nuke things back to fresh state).

I'd probably have cmake/ctest running things for the default python
and leave the rest of the tests to `tox` as it'll create the required
virtual environments for each supported version. This would be my
preference.
That said, you could also have cmake building the bindings for each
version in different paths. This will complicate the cmake step
further and I presonally think this belongs to the bindings,

Ah, turns out the 'hard problem' is not running the tests, but building both py2 and py3 binaries from the c-wrapper. Totally different include and link libraries and different install paths.
Cmake doesn't appear to directly support this - it only resolves to one instance of python, though that instance can be configured. But nowhere does it provide a list of available pythons - we'd have to script that ourselves.
Once we have that list, we should use the setup.py script to build/install the language specific module. setup.py already handles swig, so simply invoking setup.py for each available python interpreter would do all the heavy lifting.

Oh yeah - totally agreed. Just some smaller subset of python-test would make me happy. I found most problems were covered by the engine, codec, transport test modules btw. If that's all we need, then simply running python3 directly on the unit tests makes the most sense.

My system comes with both python and python3 on my path. Just running
python3 manually on proton/tests/proton-test will run it with the python3
interpreter. I don't know how standard this setup is (I'm running stock
fedora 20), but it would be pretty easy to do a check in cmake and run the
tests using python3 if present.
I'm also a fan of running both python versions if present, but I also don't
want to double the time it takes to run through the tests. Given that we
are mostly looking for syntactic incompatibilities in the wrapper code
here, I wonder if it would be sufficient to run a subset of the tests that
is likely to give us good coverage on the wrapper code but doesn't bother
trying to exercise all the C code twice. Obviously if this proves
insufficient we could expand the subset.
