Re: [Jython-dev] [Jython-users] How to build Jython standalone jar from source code

[Jim B. <jim...@py...>]

Yaqiang,

Sounds good about your progress. I'm looking forward to your changes
landing in Jython 2.7.2, which we will finally have a chance to work on
quite soon now that we are almost done with beta 3 work.

I suggest that you organize your changes as either a diff that you add to a
bug or equivalently a pull request against
https://github.com/jythontools/jython Otherwise it's very challenging for
us to review your changes, although the basic outline of what you have done
looks good. The other challenge will be to come up with good unit tests so
we can verify your fixes.

In general, Py.newStringOrUnicode() usually works, because Python 2.7 - and
consequently, Jython 2.7 as an implementation - is loose about it works
with str and unicode objects and their combination. (Making this more
strict is one of the biggest changes in Python 3.) However, I do know that
one bug you might encounter, http://bugs.jython.org/issue2295, is going to
be hard for us to fix.

- Jim
