elisa depends on Python 2.5 defaultdict

[yippi]

When I try to build elisa, I get this error:

pkgbuild: ImportError: cannot import name defaultdict

This seems to be a Python 2.5 specific feature, and I'm building with Python 2.4. I thought Elisa was supposed to work with Python 2.4. No?

[Olivier Tilloy (osomon)]

Yes, defaultdict is new in Python 2.5 (http://docs.python.org/lib/defaultdict-objects.html).
In theory Elisa should support Python 2.4, but unfortunately there may be some other incompatibilities with Python 2.4 in the code that we are not aware of, mostly because of a lack of testing/automated builds.

Any chance of fixing this soon? I really need to get my packages updated and python 2.5 isn't an option for me yet.

[yippi (brian-cameron)]

Looking at the defaultdict docs, it is a subclass of "dict". It doesn't seem that the elisa code uses any of the features of the defaultdict subclass. Just changing "defaultdict" to "dict" seems to make Elisa work fine using python 2.4.

Sorry, that was a bad attachment. The following attachment changes the defaultdict to dict. While this seems to make elisa startup okay, I think this isn't correct either. I notice now that elisa seems to hang on exit with this exception when I use this patch. Any ideas?
