After being away on vacation for a few weeks I did an svn up of z3c.pt, but
it seems things are quite broken now. Every template render attempt results
in this error:

File
"/local/simplon/2style4you/code/buildout/devel/src/tostyle4you/tostyle4you/lib/pt
.py", line 11, in render_template
template = globs["app_globals"].pt_loader.load_page(template_name)
File
"/local/simplon/2style4you/code/buildout/devel/src/z3c.pt/src/z3c/pt/loader.py",

line 47, in load_page
return self._load(filename, PageTemplateFile)
File
"/local/simplon/2style4you/code/buildout/devel/src/z3c.pt/src/z3c/pt/loader.py",

line 10, in load
self.registry[args] = template = func(self, *args)
File
"/local/simplon/2style4you/code/buildout/devel/src/z3c.pt/src/z3c/pt/loader.py",

File
"/local/simplon/2style4you/code/buildout/devel/src/z3c.pt/src/z3c/pt/filecache.py
", line 37, in load
self.registry = pickle.load(f)
File
"/local/simplon/2style4you/code/buildout/devel/src/z3c.pt/src/z3c/pt/translation.
py", line 710, in __setstate__
self.__dict__.update(GhostedByteCodeTemplate.rebuild(state))
File
"/local/simplon/2style4you/code/buildout/devel/src/z3c.pt/src/z3c/pt/translation.
py", line 747, in rebuild
symbols = state['symbols']
KeyError: 'symbols'

the z3c.pt tests all run correctly. Did something change that requires me to
adjust my code?

Yes, unfortunately we don't have a mechanism that blows the cache when
the package is updated.

Thanks, that solved it. It wouldn't surprise me if this will become a
FAQ at some point. Would it be possible to stash an ABI counter in the
cache files which is checked on load?

I'm sure an ABI counter will work, but you'll have to explain what it
is first :-) Do you mean that whenever we make a cache format change,
we should increase some integer?

Just a counter that you update whenever the binary interface changes,
which in this case would be the interface between what the .cache files
use and what z3c.pt provides.
