Re: [Zope] threading, dtml and performance

Hi all I've tried everything that I can imagine to convince my *#~!!& SUN Solaris to do Zope/Python with multitasking / threading / LWP /... NO CHANCE!!!! After about 6+ Months of on & off trying I'm giving up. I'll install my test and production system on xxxBSD or Linux (even NT runns without problems!). It's probably easier to convince my ISP of adopting Linux than finding a patch! So to all Solaris hosts out there good luck, you'll need it! The problem lies in the conjunction of the systems. Solaris, Python and Zope just dont mix with Solaris threading. My production system runs faster on my laptop on Win2k -with multitaskig- than on my high power SUN 19" rack with 4 Processors an 4GB RAM! On that note I'll just go and believe that Solaris is the wrong thing to do when thinking about Zope!! Best regards Oliver Erlewein

caching time-outs?
by Chris Ryland 25 Feb '02

25 Feb '02

I understand how the RAM Cache Manager works, I think, but what I need is something slightly different, in a couple of ways: * I'd like a cache manager that I can install in the root folder, and have it apply to the whole site (or in any folder, applying to all folder contents, including sub-folders, etc.) * I'd like to be able to cache things but have the cached elements "time out" after N minutes. Clearly, I'm not worrying about correctness, but simply efficiency. Basically, I don't care if it takes N minutes before a user sees a given change to the site (it's fairly static). Any chance? (Please reply directly, as I'm not on the list right now.) Thanks. -- Cheers! Chris Ryland Em Software, Inc. www.emsoftware.com

Re: [Zope] Zope and Databases

Do You have Oracle Client tools installed on the box that Zope is running on? I'm pretty sure that the Zope DA will need to know what and where the database you are trying to connect to is located. This information is usually supplied to Oracle Client tools via a file called tnsnames.ora. I'd recommend searching Oracle site for client tools for linux.

stack error with Python 2.1.2
by Frank Tegtmeyer 25 Feb '02

25 Feb '02

Hi, I tried to move to Python 2.1.2 with an existing site and got a stack error under some circumstances. The site provides five different websites distinguished by Virtual Site Root. The error: python: Python/ceval.c:687: eval_code2: Assertion `(stack_pointer - f->f_valuestack) <= f->f_stacksize' failed. I found some places where this is mentioned, mostly explained with illegal bytecode. Because I removed all bytecode and shared libraries before recompiling Zope and the C extensions I dont't assume that this is the case. The interesting part is: the site which was defined first (using VSR) is accessible. Every other site fails. Also the navigation frame in the management interface fails while the content frame works without problems. The Python interpreter is the (first and) only one on the system so interferences with other Python installations are not possible. The configure line for Python: ./configure --prefix=/usr/local --with-crypt --without-pymalloc --with-threads Additionally I enabled SSL for the socket module. I hope someone can reproduce this. I am not able to do debugging for this myself. I will switch back to Python 2.1.1. Regards, Frank

Are there any Zope developers in the UK? The only reference I can find is http://www.zope.co.uk which seems to be stagnant. If anyone is interested in a UK Zope developer's group then please e-mail me off-list. Cheers Tom

Upgrade Zope 2.1.1 to Current - Suggestions???
by Robert Geiger 25 Feb '02

25 Feb '02

I Would like to Upgrade my Zope installation to current version. Would like the best set of instructions available. I found this document: http://www.zope.org/Members/mcdonc/HowTos/zopeinstall/ZOPE-INSTALL-HOWTO would it be best to follow these instructions? Is there anything I should look out for, any gotcha's? Thanks. My current version information: Zope version: Zope 2.1.1 (binary release, python 1.5.2, linux2-x86) Python version: 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform: linux2 -- Robert Geiger

virtual server problem
by Frank Tegtmeyer 25 Feb '02

25 Feb '02

Hi, I just tried to use VirtualHostMonster in Zope 2.5.1b1 for a setup that is quite common at our clients. Let me first explain the setup. We use Apache with mod_rewrite and mod_proxy to access the Zope server. Zope provides typically multiple virtual servers. To be able to manage the Zope server itself we always define an additional virtual server 'z' that is located at the root of the Zope server itself: z.do.main --> mapped to / a.do.main --> mapped to /a.do.main b.do.main --> mapped to /b.do.main With VHM I was not able to provide the mapping for 'z' because VHM insists on having a path. So I installed a SiteRoot for z as always. The result was, that the VHM mapping for a and b were broken. The use of absolute_url() inside of a and b always gives urls located in z (even they were wrong). I would like to use VHM because of it's centralizing of management - is there a way to get a VHM-only solution for our setup? At the moment we use a SiteRoot at the top and virtual site roots for a and b. To avoid questions: No, we cannot access the Zope server directly from the outside. Regards, Frank

e.g.: I have a directory structure like root +-test +-test2 i have a dtml-method in the root called index_html i have a dtml-method in test called myinput How can i insert myinput in the index_html ? I need a kind of <dtml-var myinput> but including the path to test. I know the other way around would work, as the namespaces could coope with that. Thanx Dorian

Log severity without stupid log file?
by Lennart Regebro 25 Feb '02

25 Feb '02

I want to start Zope (2.3.3) with a log severety of 0 but I'm not using stupid log file, but just loggin to stdout (this is Windows). How do I do this? Using -D makes it write out everything including debug info, which I don't want. Not using -D means it only writes out errors, and not INFO level logs. I want something in the middle, ans STUPID_LOG_SEVERITY obviously doens't work. So what now?
