Yup, this was my bad -- that line should be changed to read
if validate(None, self, None, o, None):
since the C machinery isn't taking keyword arguments. Its in the
2.5.0a2 announcment. In some regards, it baffles me that it worked in
the first place, because the first 4 or 5 arguments to validate are NOT
optional, and have no default. I suspect that someone along the way was
plugging in None for those options that weren't specified. But I'm
ignorant on the exact details of Python argument marshalling... The
particular code in SecurityManager.py has a validate() method which does
supply None as defaults, but then passes them as positional parameters
to the underlying implementation. So, I think the DTML security manager
is accelerating this by skipping what basically is an empty wrapper
stage (promoting the policy's validate() method into the object), and
thats what is tripping the bug.
Alternatively, the setting the environment variable ZOPE_SECURITY_POLICY
to PYTHON will disable the C version of the security policy.
