Thank you Jens for the quick reply.

Do you have any idea about the zopectl logreopen misbehavior as
someone who's avoiding using it explicitly ;) ?
I'm afraid I don't. I have seen issues myself where the server would
just die and not come up again, but never investigated it. The
logreopen solution offers a safe and lasting fix and it even
simplifies log rotation configuration.
Here's a very simple one that rotates ZEO server and client logs for
a simple one-client ZEO setup, we use it for www.zope.de:
[EMAIL PROTECTED] ~]$ cat /etc/logrotate.d/zope.de
/home/zope/zope.de/log/*.log {

[Zope-dev] the zope, eggs and the testrunner
I've been developping some packages using zope.testing and the testrunner that ships with zope2.10. Yesterday, I packaged these using fairly standard python/egg pattern. one package is pure python, the other a zope2/zope3 hybrid. now I have two large PITAs: 1. in general, this would suck alot less if easyinstall would recognize I already have package x, y, and z on my PYTHONPATH, rather than helpfully installing incompatible ones or erroring out when it can't resolve zope dependency x from the ether. Doesn't seem to be a --stop-sucking flag that I can find. removing all the zopeish things like zope.interface and zope.testing solves this problem for the pure python package (but sort of make things like testing interfaces out of the question). 2. zopectl test doesn't see my tests with said packages installed in develop mode or as eggs (assorted --path etc options don't seem to help). Running the tests via python setup.py test only works when I unflag the testing dependency of zope.testing. anyone been down this rabbit hole? have any suggestions? resources? -w -- | david whit morriss | | contact :: http://public.xdi.org/=whit If you don't know where you are, you don't know anything at all Dr. Edgar Spencer, Ph.D., 1995 I like to write code like other ppl like to tune their cars or 10kW hifi equipment...

[Zope] Acquisition? problem
Hi all, I am writing a small object browser for the EPOZ toolbox. In the browser I have a tree of object references. Clicking on the tree should show more details of the selected object. I have created a template details that should show the details of the object, like this: /folder/selected_object/details This is all TTW code by the way. The template works fine for most values of selected_object, but for some it fails. It fails for at least PageTemplates and Python Scripts. For those objects, calling the details template will simply show the normal output of the object. Any ideas on how to solve this?

Florent Guillaume wrote at 2006-6-30 02:46 +0200: ... that's interesting. I did a test once to see what effect it would have to add objects with a completely random id to a BTree folder (OOBTree in that case) instead of using the object's type nam and add a number at the end - and the result was the opposite in term of read performance. Looking up keys was much faster if the ids followed a pattern like: - something-1 - something-2 ... Sure, in single-threaded mode this will decrease performance because the keys are spread randomly among all the buckets so many more buckets get written. But in multi-threaded mode, this very spreading leads to better conflict resolution behavior. But still can reduced performance... That's why the catalog uses the initial id randomly but then assigns id's (within a single thread) sequentially. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
