The SIGUSR1 issue is now fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=7d6a0bc558bdfe5c3ca2b6e1638d1d4f31d2d8e1 NOTE: Generally, the unit tests are the best way to begin testing a new python platform. For example, run the following command from a checkout of the portage master branch: jython2.7 pym/portage/tests/runTests You can checkout the master branch from here: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git Currently, the tests give the following error: Traceback (most recent call last): File "pym/portage/tests/runTests", line 34, in <module> import portage File "pym/portage/__init__.py", line 295, in <module> _os_overrides = { AttributeError: 'module' object has no attribute 'mkfifo' It seems that the os.mkfifo() function is missing, so somebody may want to report that here: http://wiki.python.org/jython/ReportingBugs
This is fixed in 2.1.11.4 and 2.2.0_alpha115.
It seems that os.fork(), os.pipe(), pty module, subprocess module are also missing.
that's all pretty unix-specific stuff, JVMs don't support that for a reason ;)
Actually, subprocess appears to be working in jython-2.7a2. At least with that, it's conceivable that we could get portage running.
The biggest blocker for Jython support is the lack of the fcntl module and os.O_NONBLOCK attribute, which portage relies on heavily in order to implement asynchronous non-blocking IO. Without fcntl + os.O_NONBLOCK, I guess we'd have to use threads with blocking IO, which isn't very desirable.
Jython is irrelevant because of low performance.
