changing permissions on classes/methods at runtime?
by Jürgen Herrmann 07 Mar '12

07 Mar '12

hi all! is it possible to change permissions and roles on classes/methods at runtime? normally you'd attach security declarations inline in your class definition code: from AccessControl import ClassSecurityInfo from AccessControl.class_init import InitializeClass class Cls(): security = ClassSecurityInfo() security.declarePrivate('foo') def foo(self): pass InitializeClass(Cls) now what i tried at runtime is: from mycode import Cls from AccessControl import ClassSecurityInfo security = ClassSecurityInfo() security.declarePublic('foo') security.apply(Cls) but this does not what i want it to, in fact it doesn't seem to do anything yet - probably because i'm using the wrong way :) any hints how to do this correctly would be greatly appreciated. thank you very much in advance and best regards, Jürgen Herrmann -- >> XLhost.de ® - Webhosting von supersmall bis eXtra Large << XLhost.de GmbH Jürgen Herrmann, Geschäftsführer Boelckestrasse 21, 93051 Regensburg, Germany Geschäftsführer: Jürgen Herrmann Registriert unter: HRB9918 Umsatzsteuer-Identifikationsnummer: DE245931218 Fon: +49 (0)800 XLHOSTDE [0800 95467833] Fax: +49 (0)800 95467830 Web: http://www.XLhost.de

CookieCrumbler, any new versions or replacement?
by Hugo Ramos 17 Feb '12

17 Feb '12

Yellow, I need to reuse a web application I developed around 2005/2006. This App was using CookieCrumbler as it's only authentication method but it seems that after zope 2.11.x the product is broken as it has a few imports from deprecated classes. Anyone knows about CookieCrumbler versions above 1.2 or some other replacement for this product?

"dynamic" dtml-with from string content
by Niels Dettenbach 17 Feb '12

17 Feb '12

Dear all, has somebody an idea here?: I try to define a property "my_class_path" (string) on a folder and want to use that within a dtml-with statement - i.e.: my_class_path is i.e. "folder1.folder_sub" <dtml-with "folder1.folder_sub"> seems to work, but i cant find any easy way to to use the content of the string my_class_path within the with statement. If i just have a single folder to get aquisition from, i just can use something like: <dtml-with "_[my_class_path]"> but if i have deeper pathes in my_class_path the this doesnt work. I just can do directly: <dtml-with "_['folder1']['folder_sub']"> but i can't just put "_['folder1']['folder_sub']" into my_class_path too - this didn't works too... It seems i have some tomatoes on my eyes. Can anyone push me back on the track here? Many thanks in advance... best regards, Niels. -- --- Niels Dettenbach Syndicat IT&Internet http://www.syndicat.com/

Re: [Zope] charset problems (utf-8)
by Hugo Ramos 10 Feb '12

10 Feb '12

The correct prefix in the HTML header (<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> is not needed because it affects the browser behavior only and all my 3 browsers are set to UTF-8 by default. I've checked and I have some templates encoded as utf-8 and others as iso-8859-1. This happens because some of the templates (mainly the ones encoded as iso-8859-1) come from old data.fs that I've upgraded and maintained over the years... But this doesn't seem to be the problem because templates encoded as utf-8 or iso-8859-1 all have the same problem. Any more ideas? BTW, any1 knows about some script I can use to encode everything in my data.fs to utf-8? That would be very useful!

mod_rewrite and IIS7
by Brian Sullivan 09 Feb '12

09 Feb '12

I am attempting to park Zope behind Windows 2008/IIS7 (using its mod_rewrite function) and seem to be having some difficulty getting it to work. What I want to do is make directory on Zope website look like it is a directory on an IIS7 website. I seem to be close but missing some critical element. Does anybody have a step by step process for doing this or samples of rules on IIS7 for doing something similar?

enhancements to RAM cache manager product
by sathya 09 Feb '12

09 Feb '12

Greetings, ram cached pages using the ram cache manager product seems to be a nice way to improve response times. As far as I remember it did not work well with ZEO. Is there any merit to reengineering this product to use memcached as the backend instead of ZODB/ZEO ? If so would anyone have an interest to work on this as a funded project ? It will be great to hear about newer and better solutions as well.

Zope instance not serving website - Site Error
by Matthew Moore 07 Feb '12

07 Feb '12

Hi, My rather old Zope2 server crashed yesterday and took down the one website that it was still serving. The site now just throws out the following error: "Site Error An error was encountered while publishing this resource. Debugging Notice Zope has encountered a problem publishing your object. Cannot locate object at: http://www.legulcerforum.org/news/folder_listing 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 error log. If the error persists please contact the site maintainer. Thank you for your patience. (Also, the following error occurred while attempting to render the standard error message, please see the event log for full details: main_template)" Part of the site is accessible, a zope based photo gallery and the ZMI (management interface), but the main part of the site isn't working, it just throws out the above error. I've restored the whole instance from backups and I still get the same error, so I don't think the problem is with the instance (but I'm totally new to zope, so willing to be told I'm wrong). When running the instance in the foreground - zopectl fg, I get the following - http://pastebin.com/bhBp7AXf I'm honestly not sure exactly what version of zope it is, because when I start poking around in the ZMI, I get the above error. Python is 2.4.3. The server is Ubuntu 8.04 LTS. Zope hasn't been installed through the package manager. I've never really used zope before, this is something I've inherited from a previous sysadmin. I'm happy to RTFM and try things out (this is the only site on this server and I have fairly decent backups) but my zope/python knowledge is pretty minimal, so sorry if I'm missing something obvious.

charset problems (utf-8)
by Hugo Ramos 07 Feb '12

07 Feb '12

Yellow, I've noticed charset problems displaying HTML pages. Let's say I want to display a page using a DTML Method like this: <html> <head> ... </head> <body> á Á à À ç </body> </html> This page is ok and I can see the portuguese letters fine. The problem starts when I do this: <html> <head> ... </head> <body> á Á à À ç <br> <dtml-var sometextfield> </body> </html> The first line of characters shows some strange characters and the sometextfield shows up fine even if it has the same portuguese characters. sometextfield comes from a mySQL server using utf-8 as charset and collation. zope.conf has the following: rest-input-encoding utf-8 rest-output-encoding utf-8 The browsers also have UTF-8 as the encoding (safari, firefox and chrome) all show me the same problem. I also noticed some strange behavior... If I create "á Á à À ç" as a property field using ustring and call it as <dtml-var someproperty> also gets fine in the browser. Anyone seen this??? Double encoding maybe???

Standalone CookieCrumbler is not generating http-only cookies. With PAS you can handle stuff like password strength and renewal strategies or account locking in a pluggable way.
