[Zope-dev] ZWikiZC comments

2000-08-28 Thread Ross Boylan
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

[Zope-dev] inheritedAttribute

2000-08-28 Thread Steve Alexander
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. *reads more source* Ah! About 70 lines further on in ExtensionClass.c:

[Zope-dev] New version of BTreeFolder

2000-08-28 Thread Johan Carlsson
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

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
