Two substantive comments, and some editorial ones.
You write that you are thinking of different schemes for generating
paths and ids. I suggest one of the things you consider is whether
your scheme will work if someone cuts the ZWikiZC and pastes it
somewhere else in the tree.
I'm not
In the latest Zope source, I've noticed calls to inheritedAttribute in
the Python code.
I've found the C source code in ExtensionClass.c, but it doesn't help me
understand when I should use it from Python, and why.

Ah! About 70 lines further on in ExtensionClass.c:
Hi gang,
This version just fixes a bug with the folder contents tab on Windows.
For some reason, on Windows 95 (and perhaps other platforms) the Python
interpreter behaves differently enough that if you use a class
attribute from a different module and put it in your own class, you may

I just want to check if things work the way I think (hope) it does.
In a transaction, are objects attributes safe from other threads.
self._v_mytemp in my request does not conflict with other requests?
(I suppose the have to be otherwise REQUEST's would interfere with each other.)
I know that
Oh, well, I'd bet this is a silly question. But I can not resist nor find answer by
myself.
Q: Why don't you BTree-fy all the subclasses of ObjectManager?
Is there a reason that anyone but can a newbie see?

ps. I only hope to be able to make clear statement in English, but i am

Obviously what BTreeFolder does should be available in

Using a mutex by way of example, without using anything Zope-specific
(the following uses the Python threading module):
import threading
lock = threading.Lock()
myglobal = []
def changeglobal(val):
lock.acquire()
try:
myglobal.append(val)
finally:
lock.release()

Oh, I see. Thanks for clarifying that. :)

It should be quite easy to do. I vaguely recall Steve A or Steve S
might have done it.

I did some work towards this. However, I didn't continue.
I realised that I could get the same effect by having a BTreeFolder
inside a Customizer Folder. The only downside is a slightly longer URL

Does that matter at all?
As none of the classes it is derived from have a __init__ method, I
guess not. Or, does default__class_init__ do anything

Hopefully this should only perform the extra computations when the first
part fails...

I think what I meant was this:

The ZWikiZC version 0.7.3 alpha completely rely on ZCatalog
for looking up WikiPages from WikiNames.
No references are stored in the ZWikiZG page letting cutpaste,
delete and other management actions ignore updating links.
I bellew this is a more scalable solution than in the version 0.7.2
