Pylons (0.9.6.1) on Jython Requirements/TODO

Installing Pylons and its dependencies

  • distutils and setuptools (distutils is now supported and setuptools-0.6c8 supports jython-trunk, See SetuptoolsOnJython ** for more details)**
  • 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)
  • Patches to nose for Jython compatibility: http://code.google.com/p/python-nose/issues/detail?id=160

Routes

All tests, except some which require paste.fixture (Paste is troublesome to import at this point), pass

Paste, PasteDeploy and PasteScript

requires:

  • subprocess module: if it doesn't exist (Python 2.3) it uses a version copied over from CPython 2.4 (paste.util.subprocess24) (added in r4150)
  • paste.script.util.uuid requires the Python 2.3 int/long unification (PEP 237) phase B (added in r4175)
  • modulefinder module (imported in paste/__init__.py). Jython currently lacks it, and modulefinder relies on reading code objects via marshal.load
  • 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) can be installed/imported now
  • 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 (can be installed/imported now that Paste doesn't blow up)
  • simplejson (can be installed now)
  • webhelpers.textile requires the unicodedata module

FormEncode

requires:

  • gettext (which requires the locale module, which Jython lacks) (both were added in r4077, 4084)

simplejson

  • SetuptoolsOnJython (actually distutils) currently had trouble installing simplejson because it attempts to compile its optional C extensions (that help performance). It expected to catch a distutils.errors.CCompilerError (fixed in r4157: A CCompilerError is now raised)

all simplejson tests pass!

decorator

  • requires function.func_defaults to be writable and it currently isn't on Jython (fixed in 4177)
  • 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"
