Re: [Zope] redirect to a renamed folder
by Tim Hicks 27 Jun '02

27 Jun '02

Just to let people know, I solved my problem of changing a folder name and catching old links to it. Indirect thanks must go to Casey Duncan who posted something to this list saying that python scripts halt traversal so they can populate their 'traverse_subpath' binding. I got things working by creating the script below with the old name of the folder ('cfhl' in this case). I knew it'd be easy in the end :-) tim ps context.path() is just a python script to get me a suitable url for the root of the site. ---- #Catches urls pointing to the old /cfhl/* folder tree #Redirects them to the new /hlsm/* tree import string context.REQUEST.RESPONSE.redirect(context.path()+'/hlsm/'+string.join(traverse_subpath, '/')) ---- > -----Original Message----- > From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of Tim > Hicks > Sent: Friday, June 21, 2002 11:46 AM > To: zope(a)zope.org > Subject: [Zope] redirect to a renamed folder > > > Now I'm pretty sure this is some sort of faq, but I'm really > having trouble > doing what I thought would be simple. > > The Problem: > > I have a site which needs to have one of its subfolders renamed from (say) > 'foo' to 'bar'.

Hi Toby I always thought that the object cache was per thread! If you're right then you are exactely correct and I have to up the cache accordingly. This exact Test is running at the moment so I'm curious what the results will be ;-) Zope 2.6.x ist still way off on my hosts ;-) Since you're using -t 2 on your Zopes are you also using ZEO?

Hi Jens I knew of the 7 thread limit of the DB connections but I wanted to make sure. The tests are nearly finished and I have bad news. As it appears the values for -t and -i are extremely dependant on the type of hardware used and the type of coding (mainly static or manny loops,.-..). E.g. I have noticed, that when using 20 concurrent users the max time for an answer was generally lower when using -t 3 than when using -t 7 (2%-28% faster)! This was a totally unexpected result. As I said before this seems to be a really individual thing. This means that I have to do the same tests on my production system (taking it down for that time), which means LONG nights :-( Now I'm going to test the effect of the Object Cache and -if time allows- the RAM & other caches of Zope. I hope that the performance curve there is a little more predictable.... ;-) regards Oliver Erlewein

working with sessions
by Alejandro Fernandez 27 Jun '02

27 Jun '02

Hi, Firstly: for a live site, ie one that's actually going to be used commercially, what is best: zsession or the default session environment shown at the end of the "using basic zope objects" chapter of the zope book? If the second is okay, then where can I find a howto or other docs that might show me how to set a value in a session using dtml? The reason is I don't want to have to do a python script each time I want to set a value... I don't know if this reasoning is justified... I've been trying <dtml-with SESSION mapping> <dtml-call set('banana',1)> (or SESSION.set, without the dtml-with) <dtml-var banana> But it gives a keyerror. All the examples I've found online and in the shopping cart example or in the zope book are python scripts. Is there a reason for this? Thanks, Ale -- Alejandro Fernandez Electronic Group Interactive --+34-65-232-8086--

Zsync errors
by Adam Getchell 27 Jun '02

27 Jun '02

Hello all, I have two Windows 2000 boxes running Zope 2.4.1 (Yes, I know about 2.5.1 but production is still on 2.4.1 and I can't upgrade just yet -- unless that is the fix for this problem.) I have installed Zsync 0.4.5 on each. I have a Zsync object called DEVEL on the development box, and a Zsync object called TEST on the test box. Both boxes have identical administrative accounts, and Zsync is not set to override. It is set to require approval, although I get the following error either way. I made a change to index_html DTML_METHOD (which Zsync is set to handle, by default) on the devel box. The DEVEL Zsync object has the TEST Zsync object on the test box as a destination and notes that it is out of date. When I attempt to do a sync I get the following error: Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: global name 'has' is not defined Troubleshooting Suggestions * This resource may be trying to reference a nonexistent object or variable global name 'has' is not defined. * 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 kicks, the reverse configuration (TEST with DEVEL as a destination) does not notice any change. Help or pointers would be appreciated. Once I complete this, Zope will be the best development/web application environment we've had .... *************************** * Adam Getchell AdamG(a)hrrm.ucdavis.edu * System Architect/Programmer (530) 752-1584 * Human Resources Information Systems http://www.hr.ucdavis.edu/ *************************** "Invincibility is in oneself, vulnerability in the opponent." -- Sun Tzu

[BUG] Permission mapping partially ineffective (was:[Zope] ZClass and Permissions)
by Dieter Maurer 26 Jun '02

26 Jun '02

Douwe (mailto:douwe@oberon.nl) reported: ... permission mapping has no effect for "manage_addProperty" inherited from DTMLDocument ... I analysed the problem: Permission mappings defined in the ZClass' "Define Permissions" tab itself (rather than that for a specific method/propertySheet) are ineffective. As a consequence, the permissions of inherited methods cannot be remapped. Permission mappings defined for specific methods or property sheets are effective. Accesses to such a method or property sheet are wrapped into an additional PM (Permission Mapper) acquisition wrapper that takes care of the permission mapping. Such a wrapper is missing for ZInstance accesses. This is a potential security breach, as anticipated protections expressed via a permission mapping is not effective. Workaround: If the permission mapping has the aim to restrict a permission, there is no work around. If the permission should be extended, a wrapper method can be defined that calls the original method. Its "View" permission is mapped to the desired target permission. It gets a proxy role such that it is able to call the original method. Dieter
