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
a valid sys.executable. required by setuptools and distutils for spawning subprocesses. Added in r3867, enabled via -Dpython.executable (see http://article.gmane.org/gmane.comp.lang.jython.devel/4068 )
a site-packages dir (jython needs to include it on sys.path by default). required by setuptools and distutils Added in r3886
distutils: requires [http://hg.underboss.org/jython-pjenvey/rev/1026fe32c01c a number of small patches]:
a valid sys.executable Added in r3867
getpass module Added in r3876
- 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
compile .py files to $py.class instead of .pyc distutils and these last 3 modifications were added in r3888
We don't have:
- 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.
- imp.acquire/release_lock
- This is just a simple lock, but probably needs to be used by internal imp operations. I'm not sure
- 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 a directory vs a symlink to a directory. We now support an os.stat that fills in st_mode's directory bit, but can we support lstat? (We definitely can with JNA)? Can setuptools avoid lstat completely (requiring a patch)? I don't think Java can safely determine a sym link yet. Java 1.7's JSR 203 (nio part 2) should address this as well as chmod, but we obviously need a solution for Java 1.5
