Hello zope3-dev,
I came across an error I have not seen before. Just for reference,
here is the last snippet from the traceback:
File "/home/pcardune/Work/ZContact/zcontact-lp/eggs/tmpgwuq6O/
zope.security-3.4.0b4-py2.4-linux-i686.egg/zope/security/checker.py",
line 420, in ?
AttributeError: 'module' object has no attribute 'thread_local'
I wish you had included the whole traceback.
The interesting part to me is that it was so easy to fix. Here is a
snippet of the relevant area of failing code from
zope/security/checker.py
# Get optimized versions
try:
import zope.security._zope_security_checker
except ImportError:
pass
else:
from zope.security._zope_security_checker import _checkers,
selectChecker
from zope.security._zope_security_checker import NoProxy, Checker
from zope.security._zope_security_checker import _defaultChecker
from zope.security._zope_security_checker import
_available_by_default
zope.interface.classImplements(Checker, INameBasedChecker)
The very first import statement is throwing the error, but alas, it is
not an ImportError. If I patch this code by catching the
AttributeError in the same way the ImportError is caught, then
everything works fine.
Except you don't get the C optimizations. IOW, you would just be
covering up a real error.
I tried looking into the c code, but after
years of python development, the c code just frightens me (a bit).
That said, I would really appreciate any pointers people might be able
to give me on what thread_local is for and why I (don't) need it.
I rearranged the imports in zope.security yesterday. I apparently
broke your usage, but I can't tell what your usage is. I'll need to
see the whole traceback. In particular, I'll need to see the import
order.
