Will try and see what I can do. Has to read up some on generics though. Not that familiar with java generics only used C++ templates but not that much either..

Similar caveats and opportunities apply to what is returned by findbugs. I did a couple passes through the obvious, easy-to-fix ones yesterday, and of course I completely ignored generated Antlr code as well as tests.

Given the scope of changes, I'd recommend the following:
  1. Follow our coding conventions, especially around the use of Python unittest if adding tests
  2. Verify your changes by running ant regrtest, ideally on as many platforms as you have ready access too
  3. Make certain you prepare a patch using svn diff (or equivalent)
  4. Upload to rietveld so we can review, see Frank's blog post on this: http://fwierzbicki.blogspot.com/2008/08/code-review-with-rietveld.html
  5. Repeat as necessary
Anyone else who is interested can do the same thing, and it's not limited to just fixing warnings. We welcome patches for performance, documentation, better testing, etc. The key is to follow the same sort of practice we do in development because any type of rewriting on our part creates a big bottleneck. Also, if you are going to implement a new feature (or two), it would make sense to get in touch with us on #jython or post your ideas on jython-dev.

Working on a codebase like Jython is a great way to grow as a developer, and there are many entry points. Good luck!

Start now =]

Most of them are "unchecked" type warnings. So first familiarize
yourself with the basics of Java 1.5's generics if you haven't already
(which are good to know anyway) and then start picking off some of the
easier warnings. Many of them just need you to figure out what types
are being put into a particular container, then add parameterized type
information in places that need it. It probably won't be too bad of a
generics learning experience. Feel free to ask us questions on this
mailing list or on IRC (#jython irc.freenode.net)

You'll want a nice IDE that ideally detects the same warnings Hudson
does. NetBeans/Eclipse should do it -- though you may need tweak its
settings to get all of these warnings.

E.g. this commit has a couple unchecked fixes, plus some redundant


Note that org.python.antlr.ast is auto generated code (from the ast/
asdl_antlr.py script), so don't try fixing their .java files directly.
I'd also say the javatests/ aren't as high priority as the others
(plus the warnings I saw in there aren't very straightforward fixes).
