[Zope-dev] Zope crash problem

2002-03-14 Thread Stefano Noferi
Hi My experiences with zope 2.5.1b1 and python 2.1.2 crashes are now only with CMF 1.1 installed. The new system with plugin indexes implemented in zope 2.4.x (with text fields plugin splitters compiled in c as python modules for optimization) is a diff with stable zope 2.3.3 platform.. Can

Hi all, I have isolated the memory leak problem on a naked 2.3.3 Zope. I have on ZPsycopgDA and two SQL Methods, one SQL Method contains DTML-IFs and DTML-ELSEs and REQUEST.sets the other SQL Method contains the rendered query of the first, this means there is pure sql in it. Both methods cache

Hi all - In an effort to better keep up with the collector, I'd like to throw out the idea of doing periodic bug days (a la the mozilla bug days), where Zope geeks and committers would get together on IRC and spend a few hours knocking out issues. I've drafted a preliminary bug day manifesto

Attached is another diagnostic patch which you might apply to Python. If you apply this patch, you WILL need to rebuild Zope to include it. What it will do is complain to stderr if an object is INCREF'd from refcount 0. It also silences the complaint for the one area which I know revives
