 * the kicker, a working os.chdir. I hacked together [http://hg.underboss.org/jython-pjenvey/rev/51246729a616 a really quick version of this ], and setuptools was able to get pretty far at installing Pylons. Pylons itself and a number of its dependencies installed fine, but the process died installing the decorator module due to marshal raising a KeyError

 * working marshal. setuptools uses marshal.load, and there's some bugs with our current marshaller  * working marshal? setuptools uses marshal.load in a couple places, which either needs to be avoided or possibly some work done to Jython's marshal module

Setuptools requirements:

  • PEP 302 style zipimport module Added in r3463

  • number of misc. Jython bug fixes most already committed

  • file descriptor support for tempfile.mkstemp, os.open and tarfile Added in r3711

  • tempfile.mkstemp Added in r3712

  • os.chdir (also needed for distutils) Added in r3844

  • tarfile module Added in r3850

We don't have:

  • working marshal? setuptools uses marshal.load in a couple places, which either needs to be avoided or possibly some work done to Jython's marshal module
  • tarfile module. This requires [http://hg.underboss.org/jython-pjenvey/rev/3507a9b953fa a small patch to PyString] to work for setuptools

  • a valid sys.executable. required by setuptools and distutils for spawning subprocesses. It's impossible to determine argv[0] from java: I'm thinking the jython executable should pass this information along to Jython (java -Dpython.executable=$0)
  • distutils: requires [http://hg.underboss.org/jython-pjenvey/rev/1026fe32c01c a number of small patches]:

    • - distutils metadata for the os.name == 'java' (like path names, default bdist type, etc) - a jython spawn-like function: "error: don't know how to spawn programs on platform 'java'". os.system works as a replacement - a valid sys.executable
  • imp.acquire/release_lock
    • This is just a simple lock, but probably needs to be used by internal imp operations. I'm not sure
  • setuptools runs a test to ensure .pth files work by running "sys.executable -E -c pass". -E is ignore environment on CPython, but is different on Jython (takes an argument):
    • -E codec : Use a different codec the reading from the console.
  • a site-packages dir (jython needs to include it on sys.path by default)
  • os.chmod. This can be implemented with JNA. We can still support setuptools on deployments lacking JNA if we submit a patch back to setuptools to only use chmod if it exists
  • os.lstat. setuptools cut and pasted shutil's rmtree from CPython 2.3, which uses lstat to check for directories. We can support an os.stat that fills in st_mode's directory bit, but can we do lstat (we could with JNA)? We may want to submit a patch to setuptools to avoid lstat (it could avoid it if it used os.path.isdir)
