I am trying to make a new Zope product, based on LocalFS, so I am trying to change the source code of LocalFS. But in my product, I need to know who is the authenticated user when someone tries to read a file in the local filesystem by writing its URL. The problem is that if I ask UserManager in any function in the source of LocalFS, it always tells me that it is no one. I think I read somewhere, sometime, that the authenticated user can't be read until the end of traversal. So the changes that I have to make in the source code, have to be made somewhere where the traversal has already finished.
Apparently, there is a "validation_hook". Look at "Zope/__init__.py". You find the traversal code in "ZPublisher.BaseRequest.BaseRequest.traverse".
... - Does anybody know all the functions that are called in the Zope sources when someone writes the URL of a file in the local filesystem?
You can use a profiler (e.g. "ZopeProfiler" <http://www.dieter.handshake.de/pyprojects/zope> ). However, you will get an incredibly long list.
- Or else, how can I know all the functions that are called, without having to put traces in all the functions in all the Zope source?
A profiler... Dieter
