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)*
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, maybe jython could provide a broken compiler module that doesn't import parser
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 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"
