[jira] Created: (ZOOKEEPER-877) zkpython does not work with
python3.1
zkpython does not work with python3.1
-------------------------------------
Key: ZOOKEEPER-877
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-877
Project: Zookeeper
Issue Type: Bug
Components: contrib-bindings
Environment: linux+python3.1
Reporter: TuxRacer
Fix For: 3.3.1
as written in the contrib/zkpython/README file:
"Python >= 2.6 is required. We have tested against 2.6. We have not tested against 3.x."
this is probably more a 'new feature' request than a bug; anyway compiling the pythn module and calling it returns an error at load time:
python3.1
Python 3.1.2 (r312:79147, May 8 2010, 16:36:46)
[GCC 4.4.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import zookeeper
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /usr/local/lib/python3.1/dist-packages/zookeeper.so: undefined symbol: PyString_AsString
are there any plan to support Python3.X?
I also tried to write a 3.1 ctypes wrapper but the C API seems in fact to be written in C++, so python ctypes cannot be used.

[jira] Updated: (ZOOKEEPER-877) zkpython does not work with
python3.1
Posted by "TuxRacer (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/ZOOKEEPER-877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
TuxRacer updated ZOOKEEPER-877:
-------------------------------
Attachment: Doc.tgz
zookeeper.rst
Adding also a documentation file zookeeper.rst in RST format (standard documentation format for python).
The information has been taken from the ./src/c/pyzk_docstrings.h file.
Attaching the Doc environment in Doc.tgz
To build it just run:
sphinx-build Doc html
It is in theory possible to generate an HTML doc directly from the C docstrings but almost impossible to get a nice HTML ouput.

TuxRacer commented on ZOOKEEPER-877:
------------------------------------
the new file streams handling introduced with the above patch should work with both python2.6 and python3.1, so the code could probably be simplified removing the 2.6 conditional compilation preprocessor directive.

[jira] Updated: (ZOOKEEPER-877) zkpython does not work with

Posted by "TuxRacer (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/ZOOKEEPER-877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
TuxRacer updated ZOOKEEPER-877:
-------------------------------
Attachment: zookeeper.c.patch.v1
zookeeper.c
tests_py3k.tgz
Please find my first attempt to resolve this issue as three attachments
The zookeeper.c file (full code attached + diff file) now supports a compilation with python3.1 and python2.6.
(I used conditional compilation as recommended at
http://docs.python.org/py3k/howto/cporting.html )
I converted the python test to py3k syntax using the '2to3' tool.
So we probably need to add a 2nd directory in the tree (and call it maybe 'tests_py3k'?)
good news:
all the test pass
bad news:
I could not make logging work (so had to comment the log setup in the tests)
Please let me know what you think, thanks. TuX

------------------------------------
In py3k PyString_AsString does not exist
see http://www.velocityreviews.com/forums/t674572-where-is-the-pystring_asstring-in-python-3-0-a.html
There is no PyString_AsString. Everything string is unicode now. (PyUnicode API)
example:
PyString_FromString -> PyUnicode_FromString
PyString_Concat -> PyUnicode_Concat
etc...
To get a char * you have to explicitly encode the string with
PyUnicode_AsEncodedString.
