Zope reference counts
by Ivo van der Wijk 24 Jan '03

24 Jan '03

Hi, I'm currently optimizing/analyzing a Zope server and I noticed the following: The number of references to specific objects (in this case specifically Squishdot comments) increases almost linear with the number of threads. Does this mean each thread keeps it's own cache pool of objects? Do these references point to the same object instances, or are these copied as well? I have the impression the memoryconsumption grows with the number of threads - is this true? Cheers Ivo -- Drs.

Registering Product with Control Panel
by Brian R Brinegar 23 Jan '03

23 Jan '03

Okay, I've got a product (Basic content object) Called HTMLBlock. When I start my ZEO Client with the product installed I don't recieve any error messages. The product is listed in the "Select type to add..." menu. However if I try to add an instance of the Product I recieve an AttributeError on HTMLBlock. After a little poking around I realized that the product is not listed in the /Control_Panel/Products/ list. The traceback I get when trying to add an instance is below. Thanks, -Brian Traceback (innermost last): File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/ZPublisher/Publish.py, line 89, in publish File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/ZPublisher/BaseRequest.py, line 278, in traverse File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/App/FactoryDispatcher.py, line 30, in __bobo_traverse__ File /data/www/Zope.mysql.pes161.HB10/src/Zope-2.5.1-src/lib/python/App/Product.py, line 66, in _product (Object: Products) AttributeError: HTMLBlock

Newbie security development question
by David Cain 23 Jan '03

23 Jan '03

Running Zope 2.6.0 (binary release, python 2.1, linux2-x86 I would like to import the ClassSecurityInfo class from a Python script and the examples don't seem to work: If I try for the examples: from AccessControl import ClassSecurityInfo It doesn't work so when I try: from AccessControl.SecurityInfo import ClassSecurityInfo I get password challenged, and no username/password pair works (not even admin, or the emergency user). Can anyone tell me what I'm doing wrong here? Ultimately I want to change the default permission on an uploaded file to not be viewable by anonymous, until a manager approves this and sets it viewable.

Can't import
by David Cain 22 Jan '03

22 Jan '03

I have a simple python script that tries to do the following: from AccessControl import ClassSecurityInfo And produces the following error: Error Type: ImportError Error Value: import of "ClassSecurityInfo" from "AccessControl" is unauthorized. You are not allowed to access ClassSecurityInfo in this context I think all other from...import statements cause the same. Can anyone tell me what this is caused by, and how to work around it?

Re: [Zope-dev] [PATCH] Forking daemon in debug mode, and new start scripts
by Adrian van den Dries 22 Jan '03

[Sorry about the broken thread] On January 20, Guido van Rossum wrote: > You seem to forget that in debugging mode there are other things that > happen (or not) besides logging. Ah, the infamous Zope side-effect, aka "other cool stuff". :-) Thanks for the heads-up. > And you can log to stderr (that's what I use 99% of the time). But this means I can't really write a start script that works (or makes sense) with debug mode both on and off. Redirecting stderr to EVENT_LOG_FILE doesn't really make sense if we're detaching, and is ugly, etc.. I could write some shell polava to figure it out, but: > Maybe the "debug" flag is misnamed? All it really means is "don't > detach". Yes. I would much prefer an explicit flag for each, because I run a number of dev Zopes on a number of boxes to which I only have ssh access, and I don't want to have to remember to play games with my stdio, or restart Zope if I restart screen, etc. Speaking of the (side-)effects of debug mode, what exactly are they? Is it just the automatic re-loading of DTMLFiles and PageTemplates from disk? a. -- Adrian van den Dries adriand(a)flow.com.au Development team www.dev.flow.com.au FLOW Communications Pty.

AdaptableStorage
by seb bacon 22 Jan '03

22 Jan '03

Shane, AdaptableStorage is insane and beautiful - congratulations :-) It could fit a possible project we have coming up where a requirement is to store content in an XML format inside MS SQL Server. Do you have a TODO list? Are there any "particularly alpha" parts? I would need to get an idea of the risk I was taking on, but if the list is sufficiently small, I love to help mature and extend the product. Seb

Zope anonymous CVS temporarily offline
by Martijn Pieters 22 Jan '03

22 Jan '03

Hi all, Due to the CVS vulnerabilities disclosed today, we have temporarily shut down anonymous CVS access to cvs.zope.org through pserver. We'll reenable this when we have upgraded CVS on the server. People with write access through SSH and the web interface at http://cvs.zope.org are still available. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------
