Hi!
I didn't know that methods needed to have docstrings to be traversable (it took me some time to find out why I was getting "Not found" errors on some of a tool's methods). Is there any reason to still have such a "feature" in Zope2.9? or at least maybe there could be a hint in the trace log.
regards /JM

"Publishable methods have docstrings" is the oldest security model in Zope / Bobo. It would open unknown security holes in 3rd party applications if we removed that restriction. Even setting the default value of '__allow_access_to_unprotected_subobjects__' to False wouldn't help, because there are many products which set that to True for their objects, relying on the lack of docstring to make their methods safe from direct URL access.
In fact, this restriction is *different* than the "permission-role" one: even methods whose roles are None (i.e. public), and therefore can be called by scripts run by anonymous users, are prevented from being "published" if they have no docstrings.
or at least maybe there could be a hint in the trace log.
I *thinK* if you run in debug mode with verbose security turned on, it suggests that as one possible reason.

If somebody gets time to do the suggested refactoring of the publisher for 2.10, then the docstring requirement could be dropped for IFiveTraversable objects, I think.
or?

Otoh, whats wrong with docstrings anyway? :-)

One extra difficulty when debugging with that model is that .pyc files must be deleted if the .py is modified. since apparently docstrings are ignored during the compilation.
But now I know :-)

This is not the case (unless you use "-OO" and even then, the ".pyc" file would be recreated).

I thought the docstring requirement only applied to publishing, not traversal per se? Do you get "Not found" when doing e.g. restrictedTraverse(some_path)?

no then it works, and also when methods are called from inside page templates. That's the publisher that doesn't find it.
