Hello everyone, I'm new to LINUX, ZOPE, PYTHON, and this mailing list. I have a ZOPE server running on Linux and I'm trying to get my forums to work. They require PHP and mySQL both of which I have but I'm not sure how to install them into my ZOPE server. Any suggestions? ~Mosquito

privileges problem
by Catonano 24 Dec '02

24 Dec '02

Hello all, I'm tring to execute this script: lista = [] folder = container.indice2() #indice2 is a ZCatalog for file in folder: if not file.hasProperty('codice'): lista.append(file.id) attributes=getattr(folder, file) attributes.manage_addProperty('codice', 'inserted yet', 'string') return lista I borrowed the idea from the /Examples/GuestBook/addEntry script Zope prompts me for a user name and passwd, I type my usual account data (I'm the only user and I think I have full privileges) and BAM! Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access in this context Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the HTML source for this page. If the error persists please contact the site maintainer. Thank you for your patience. I tried to give the script all the proxy roles I could I opened Control Panel/acl_users and gave manage property permission to managers and owners (I'm a manager user): NOTHING! Please: what's going on? Thanks anybody who will help me Bye Catonano

version trouble
by Steffen Hausmann 25 Jun '02

25 Jun '02

Hi, I'm working with Zope 2.4.3 on a linux SuSE 7.0 system. I was just editing my homepage using a version ( called 'tmp' ) and 2 different browser windows ( mozilla 0.9.7 ). Then I decided that the changes I had done are ok, saved them and quited the version ( in the first browser window ). After that I found a small mistake in one of my sites and corrected it ( in the second browser window ). Somehow the version was still active and the changes were made inside it. But, it wasn't the same verion. The version the changes were made in is called 'No longer active'. I can start and quit working with that version by starting and quitting the original version tmp. But if I want to save / discard the canges there is just the message 'No unsaved work has been done in this version' The link of the version 'No longer active' points to the root directory of Zope ( I was working in the folder 'hausmann-family' ), but there is no version at all. How can I get rid of this version? Some files are locked and I can't delete them or do anything else with them. Thanks, Steffen -- Es gibt keine perfekten Menschen, nur perfekte Absichten.

What is the Best Way to Include CSS Stylesheets in Zope
by zvi＠12thplanetcafe.com 31 May '02

31 May '02

I would like for all of my Zope pages to use a CSS stylesheet by default. Ideally I would be able to keep the reference to the stylesheet in only one place in Zope and have changes to the stylesheet filename propagate globally. The Beehive book does not mention anything about how to integrate CSS stylesheets into Zope. Does anyone what is the best way to do so?

Zope 2.5.0, thread stack issues
by Geoff Gerrietts 09 May '02

09 May '02

I'm in the process of moving a site from a (much) earlier release of Zope, up to 2.5.whatever. In making this migration, I have encountered a problem with segmentation faults and spontaneous Zope restarts that sounds an awful lot like the problems some BSD users were encountering earlier. The principal difference between my case and theirs is that they're on BSD, where the thread stack size is by default yitty-bitty (64k), and I'm working on Linux, where the thread stack size is by default really huge (2MB). The solution previously recommended was to boost the thread stack size to 128k; Linux already provides well more. It's also a lot harder to boost the stack size under Linux; if there's a way to do it short of recompiling glibc, I don't know what it is, yet, and I've spent a lot more time than I should trying to find one. Now the symptoms I'm seeing pretty obviously have more to do with the signal handler for segfaults than any particular manifestation of segfault, but early triage attempts pointed at this thread stack problem. So, because I can't find hard diagnostic details in the mailing list archives, I'm hoping that someone might be able to tell me what the best indicator would be, or how to go about demonstrating that it isn't this problem.
