[Jython-dev] problem with multi level import

[<Mat...@i2...>]

Hi,

I had a problem with multi level import from a jar file in my sys.path.
basically, my simple test jar looks as follows, with the init files being 
empty, and the py files having a simple variable def:

jlib.jar:
Lib/
Lib/aaa/
Lib/aaa/__init__.py
Lib/aaa/bbb/
Lib/aaa/bbb/__init__.py
Lib/aaa/bbb/ccc/
Lib/aaa/bbb/ccc/__init__.py
Lib/aaa/bbb/ccc/yyy.py
Lib/aaa/bbb/xxx.py


import aaa works fine
import aaa.bbb (or more levels) doesn't

I traced the problem down to the following line from the method 
"loadFromZipFile" on line 302 in org/python/core/imp.java
                SyspathArchive subArchive = 
zipArchive.makeSubfolder(modName);
Which should probably be
                SyspathArchive subArchive = 
zipArchive.makeSubfolder(name);

Or at least, when I change it to that, all levels of import work for me =)

If I have to do more complicated changes, whats the best way for me to 
generate a patch?  I'm somewhat of a CVS/patch/diff newbie, so excuse me 
if this is a simple question.  Do I need to have 2 CVS directories, one 
untouched to generate the diff against?  Can someone give me a simple 
usage scenario as an example of generating a patch?  Thanks,

Matt
