* 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 |

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)
