Package: zope3
Version: 3.2.1-4
Severity: normal
Tags: patch
After some updates this week, zope3 stopped working for me. Starting a
zope3 instance would go well, but any http access failed. The stack
trace always ended with:
File "/usr/lib/python2.4/site-packages/zope/app/twisted/http.py", line 59, in
<lambda>
return x.addCallback(lambda data: (self.res, segments))
exceptions.AttributeError: 'Prebuffer' object has no attribute 'res'
It seems that in zope/app/twisted/http.py, the Prebuffer class overrides
the locateChild method of WrapperResource from twisted/web2/resource.py,
and over there self.res is now called self.resource. Because the
implementation of the function is now identical in both classes, I tried
commenting out the function in Prebuffer. That got everything back to
work.
The patch is trivial:
