Pylons (0.9.6.1) on Jython Requirements/TODO
Installing Pylons and its dependencies
- distutils and setuptools (Mostly finished, See SetuptoolsOnJython )
- Ensure all dependencies' tests pass
nose
Pylons projects require nose, but most packages (including Pylons) use nose as their own test runners.
requires:
- optparse module (added in r4018)
- a fix for the cell variable (variables used in closures) bug here: http://pylonshq.com/pasties/667 (fixed in r4038)
- fix for new.instancemethod not allowing a PyType as its class argument (fixed in r4051)
- fix for inspect.argspec not working (also needed for Pylons, among other things) (fixed in r4053)
- imp.find_module returned entries in regard to bytecode files instead of .py files when they were available (fixed in r4080)
- fix type names and class __module__ in doctests (fixed in r4107, 4111)
- methods weren't always inheriting their inner functions' __name__ and __doc__ (fixed in r4109)
- compiler package (and compiler requires the parser module which Jython lacks). nose only needs the compiler module to use compiler.consts.CO_GENERATOR; until there's a parser jython will provide a broken compiler module that doesn't import parser (added in r4114)
Routes
All tests, except some which require paste.fixture (Paste is troublesome to import at this point), pass
Paste, PasteDeploy and PasteScript
requires:
- modulefinder module (imported in paste/__init__.py). Jython currently lacks it, and modulefinder relies on reading code objects via marshal.load
- subprocess module: if it doesn't exist (Python 2.3) it uses a version copied over from CPython 2.4 (paste.util.subprocess24). paste.util.subprocess24 dies on attempting to import fcntl, so Jython needs to provide subprocess
- webbrowser module: paste.fixture imports it. Jython doesn't include it. It's a pretty simple module -- though it doesn't seem to work right on Jython when launching a console browser (like lynx or links). I think it's an os.system problem
Mako
requires:
- compiler module: to parse Python code into AST. The compiler module is mostly pure Python code, but its guts are really the native parser module (which Jython lacks)
Beaker
requires:
- Paste (for paste.fixture)
- base64.b64encode: might die on an attempting to import b64encode in beaker.crypto.PBKDF2 (at least it does when the tests are run)
WebHelpers
requires:
- routes
- simplejson
FormEncode
requires:
- gettext (which requires the locale module, which Jython lacks)
simplejson
- SetuptoolsOnJython (actually distutils) currently has trouble installing simplejson, because it attempts to compile its optional C extensions (that help performance). It expects to catch a distutils.errors.CCompilerError if the compilation fails, but Jython dies much earlier:
File "/Users/pjenvey/src/java/jython-trunk/dist/Lib/distutils/command/build_ext.py", line 598, in get_ext_filename
TypeError: cannot concatenate 'str' and 'NoneType' objects
decorator
- Note: decorators aren't currently supported in Jython, however the decorator module doesn't actually use decorators (works on CPython 2.3)
Later down the road
SQLAlchemy
- The Dialect Refactor II ticket will need to be implemented to properly support using SQLAlchemy via Jython's DBAPI jdbc driver, zxJDBC.
- Frank Wierzbicki has done some preliminary work on using SQLAlchemy with Jython, info here, and is scheduled to give a talk at PyCon 2008: "Database development with Jython, SQLAlchemy, and Hibernate"
Turbogears 2
- Jim Baker has already started playing with Genshi on the Jython modern branch
