Image upload fails on Linux PIII/550
by Michael Hamilton 17 Jan '00

17 Jan '00

I wonder if anyone else is having a similar problem: I have an identical setup on a Pentium PII 266 and a PIII 550. Both running Caldera Open Linux 2.3 with python 1.5.2 and Zope 2.1.2. Both Python and Zope were built from source. Caldera 2.3 uses glibc-2.1.1 egcs-2.91.66 19990314 (egcs-1.1.2 release). Creating new image objects on the PII works fine, i.e. I can view the image after creating it. Creating a new image object on the PIII results in a broken image. I have since transfered the PIII's Python and Zope installations to the PII. The images originally created on the PIII are still broken, but I have no problem creating new ones. I checked for differences in the RPMS installed on both boxes, and I've checked that the environment and user setups are the same. I now suspect there could be a problem in the libraries or compiler, or possibly an architectural assumption/bug in the Zope or Python code. I've seem other image loaded problems reported recently, are these people also using PIII's? I'm working around the problem by putting the images in directory and using the LocalFS product to make them available within Zope. --- Michael Hamilton ( http://home.clear.net.nz/pages/michael.hamilton )

mod_rewrite to a different port?
by Erick Mechler 17 Jan '00

17 Jan '00

Is it possible to use mod_rewrite and have Zope appear on a different port? Here's some more info... Right now I can go to http://my.domain/cgi-bin/Zope/ and see my site through Zope. However, I would like to define a RewriteRule to have this point to http://my.domain:8080. The reasoning for this is because all of the images in the Zope site are defined using absolute path names with respect to the document root. Therefore, all of the images in the http://my.domain/cgi-bin/Zope/ site don't work. I am not using ZServer, but rather Apache + Zope + SSL. Any help/links/beatings-because-this-is-a-dumb-question will be much appreciated. Regards, Erick Mechler

Re: [Zope] Zserver logs
by Anthony Baxter 17 Jan '00

17 Jan '00

>>> Graham Chiu wrote > Is it possible to configure Zserver to produce logs with domains rather > than just IP addresses? Most systems nowadays log IP addresses rather than names - to do names, you have to do a reverse lookup of the address. Given the fairly woeful state of the in-addr.arpa. space, this can take some time, and this will have a _major_ performance impact on your system. The best way to do what you want is probably to post-process the logs using something like logresolve (http://www.aceldama.com/~tomr/progs/logresolve/) or similar. There's a bunch listed at http://ntua.linuxberg.com/conhtml/adm_log.html and also at http://www.freshmeat.net/appindex/console/log%20analyzers.html Perhaps someone looking for a small project could put together a how-to listing log analysers that work on the Z2.log format...

new dtml syntax
by Jeff Bauer 17 Jan '00

17 Jan '00

Hi all. I'm attempting to use the new dtml syntax convention, documented in Pamela's fine Document Template Markup Language reference. The server complains if I use  syntax, but works okay for . I assume the possible problem might be: 1. The new syntax is not supported in the latest stable Zope 2.1.2 release. 2. My server is loading an older version of DocumentTemplate.HTMLFile. (I've already checked this.) The individual Zope components used to be available for separate download, but I can't find them anymore. If downloading a more recent DocumentTemplate from a beta version will allow me to play with the new dtml syntax, I'll be happy to try that. Thanks. Jeff Bauer Rubicon Research

Quick Permissions Question
by Alexander Limi 16 Jan '00

16 Jan '00

Zopistas, Just a quick question here - the Owner role; does it inherit permissions from Manager, Anonymous or nobody? The problem is this: I want to give the users of my site limited permissions in their own directory, they should only be able to do a select few things. Is the Owner role the preferred way of doing this, or is it better to create a new role with just a few permissions? In other words, can I limit what the Owner can do in his own folder, or does he automatically have Manager-like permissions in his own folder? A pretty basic question, but I couldn't find a straight answer, and I don't want to make any security holes in the site. Thanks in advance. Alexander Limi http://mp3.no
