A *major* change between 2.1.x and 2.2.x is in the security dept. 2.2.x runs all methods using the security level of the _owner_ of the method, regardless of whether this is a lower or higher level than the currently authenticated user. My guess is that your method has no owner (which is what pre-2.2.x objects default to when run under 2.2.x). This means it is running as anonymous which does not have rights to do what you want. Specify an owner for the method that has sufficient rights to do what you want and try it again. Good luck, -Casey Duncan

We need more info about Zope from a Python programmers POW. Setting pages up in dtml is not that interresting from my point of view. We need more detailed documentation on all the seperate modules, and far more/better on making products. dtml is not for programming and business logic, only for presentation. Max M

Re: Xron test
by Loren Stafford 18 Aug '00

18 Aug '00

Nick, Two other Zopistas reported similar problems. Both succeeded eventually in getting Xron started, but we didn't succeed in diagnosing the problem, nor in determining precisely how to work around it. I myself haven't been able to reproduce the problem. The problem seems to occur only on Linux, but it does not always occur. Some users have successfully started Xron on Linux with no problem. The problem seems to have to do with contention for a lock on ZODB. Did you see any log or console message that would confirm this? One user went to the console and killed all the Zope processes that were running at the time, then restarted Zope from the command line. The second time, Zope started up correctly with Xron. Another user thought that he had mistakenly tried to start Zope while logged in as root. When he restarted as a different user, Zope started up with Xron correctly. I suspect that the user was not relevant to the Xron problem (it is normal in some installations to start as root), but that the restarting was the key. One user thought that the monitor process contributed to the lock contention. I don't know, but it might be worthwhile to try to restart Zope without the monitor (changing the start-up options to disable the monitor). The problem seems to relate to Xron's creating the Schedule catalog the first time the Xron product is loaded during Zope start-up. If you succeed in creating the Schedule one time, the problem will not recurr, as Xron will just use the existing Schedule. I hope that helps you get started. Let me know how it goes. I'll copy this email to the zope list in hopes that someone else can shed some light on the problem. -- Loren ----- Original Message ----- From: "Nicholas Lo" <nicklo(a)siliconcreation.com> To: <lstaffor(a)dynalogic.com> Sent: August 18, 2000 12:41 AM Subject: xcron test > Hi Loren, > > I have a problem with installing Xron 0.9 onto my machine.

Can't change title of a common instance property sheet
by Jeff Sasmor 18 Aug '00

18 Aug '00

I suppose this is some sort of lack in the Zope management UI, but maybe someone else knows how to do this: If you create a ZClass property sheet you can pick an ID and a title. But you don't seem to be able to EDIT the title of the property sheet ever again. Is there some magic property sheet property name or is there just no way to edit the title from the management interface? The other bizzare thing is that you can export a property sheet, but there seems no obvious way to import one anywhere. Anyone have a clue on this? What's it there for? TIA Jeff Sasmor jeff(a)sasmor.com

Pb getting local roles ... strange
by Didier Georgieff 18 Aug '00

18 Aug '00

Hello, I'm on 2.1.6. I'm trying to have an information box with all roles. <dtml-in "AUTHENTICATED_USER.getRoles()"> <dtml-var sequence-item> </dtml-in> works OK. But doesn't give the local roles. So i tried <dtml-with URL0> <dtml-in "get_local_roles()"> <dtml-var sequence-item> </dtml-in> </dtml-with> But it only gives ['owner'] and not the other local role ['roleFoo']. But the response is correct if i test with <dtml-if "AUTHENTICATED_USER.has_role('roleFoo',this())"> is True. Is it a bug or a misunderstanding ? I found nothing on the archives. Thanks in advance. -- Didier Georgieff DDAF du Bas-Rhin - Cellule SIG 2, rue des Mineurs 67070 Strasbourg Cedex tél : 03.88.25.20.33 - fax : 03.88.25.20.01 email : didier.georgieff(a)agriculture.gouv.fr GéoWeb http://10.67.90.3 (Intranet Agriculture) GéoWeb http://sertit10.u-strasbg.fr (Internet)

ANNOUNCE: updated Hotfix release for recent mutable object issue
by Brian Lloyd 18 Aug '00

18 Aug '00

Hi all - We recently made a Hotfix release to address an issue dealing with Zope APIs returning mutable objects that could be changed inappropriately from DTML (Hotfix_08_09_2000). After further investigation, there was another aspect to the problem that was not addressed in the recent hotfix. I've uploaded a new hotfix release (Hotfix_2000-08-17) that supercedes the one from the 9th and includes the extra fix required. http://www.zope.org/Products/Zope/Hotfix_2000-08-17/ If you run a Zope site and allow untrusted users to edit DTML on your site, you should install this updated hotfix. There is no need to uninstall the prior hotfix release. These fixes will also be in the 2.2.1 release, expected next week.

Product question, third posting
by Daniel Rusch 18 Aug '00

18 Aug '00

I've created a folderish product. When I select that product from the available objects list, thus creating an instance of that product, I can create objects like dtml document and dtml method in the new folderish object (very similar to what happens when you instantiate a folder object, you can have a dtml method created in the new folder). The question is why can't I create objects from the Products directory, such as Local File System????? The code below works great, I get a dtml document, two folders each with a dtml method in them.... HOW CAN I CREATE A LOCAL FILE SYSTEM OR ANY OTHER OBJECT FROM THE PRODUCTS DIRECTORY IN THIS MANAGE_ADD FUNCTION??????? def manage_addSimpleSite(self, id, title='', createNewFolder=0, createEditFolder=0, REQUEST=None): """Add a new SimpleSite object with id *id*. If the 'createNewFolder' and 'createEditFolder' parameters are set to any true value, an 'New sub Folder' and an 'edit sub Folder' objects are created respectively in the new SimpleSite. """ ob=SimpleSite() ob.id=id ob.title=title self._setObject(id, ob) try: user=REQUEST['AUTHENTICATED_USER'] except: user=None ob.manage_addDTMLDocument(id='index_html', title='') if createNewFolder: if (user is not None) and not ( user.has_permission('Add User SimpleSites', self)): raise 'Unauthorized', ( 'You are not authorized to add User SimpleSites.' ) ob.manage_addFolder(id='New'+id, title='', createPublic=1) if createEditFolder: if (user is not None) and not ( user.has_permission('Add Documents, Images, and Files', self)): raise 'Unauthorized', ( 'You are not authorized to add DTML Documents.' ) ob.manage_addFolder(id='Edit'+id, title='', createPublic=1) if REQUEST is not None: return self.manage_main(self, REQUEST, update_menu=1) Thanks, Dan
