Hi Richard, How did you do this last step of setting the message to the type and value of any exception raised in the PUT method? cheers, Chris

Per restart volatile attributes in Zope?
by Morten W. Petersen 25 Nov '01

Hello, I'm wondering if there's a volatile attribute type in Zope, where the attribute is deleted each time Zope restarts (or something similar). Thanks, Morten

RE: [Zope-dev] SiteAccess improvements

One thing that might be nice - and something I was planning on working on relatively soon was a rewrite rule wizard to extend VHM to auto-write rewrite rules for use with a front-end Apache/Squid; this would support mod_rewrite and Pyredir (a python-based Squid redirector). The idea would be that the rules could be copied by a site admin from their browser viewing a VHM management page and pasted into Apache's httpd.conf or a Squid redirector's conf file. I don't have code yet, but eventually plan to do this; would this kind of modification be useful to anybody? In the long run, if a "registry" of virtual host monsters is in the control panel, and could be queried via XML-RPC, it seems an Apache module or Squid redirector could be built or modified to make those servers use that data automatically! I would be tempted, for example, to hack Pyredir (since I primarily use Squid), to use its conf file for most of its rewrite rules, but query Zope via XML-RPC for supplementary rules associated with VHM instances as well on initial load or SIGHUP or Pyredir.

RE: [Zope-dev] Wild and crazzzzy idea: Hierarchial permissions
by sean.upton＠uniontrib.com 23 Nov '01

23 Nov '01

Perhaps what might be nice is an arbitrary, user-selected grouping that keeps a mapping of default and user-created categories for permissions, and allows one permission to be mapped to several groups, even in a hierarchy: + Permissions, Sorted by Product/Interface - MyProduct -> View Management Screens [x] -> Access Contents [ ] -> Edit CRM Profile Data [ ] + ObjectManager + etc... + Permissions, Custom Sort + Permissions Used in My Application -> View Management Screens [x] -> Edit CRM Profile Data [ ] + Other permissions etc... I wonder if this is doable with a monkey-patch? Another thought is something like this, with the addition of a permissions-template that is a canned set of selected permissions...

Hi! With OrderedFolder, you can at least clean up the Add menu locally. That might help for a lot of situations. It is not creating tree views yet, but it's a start ...

LDAP
by Magnus Heino 23 Nov '01

23 Nov '01

Hi. I'm struggeling with zope, cmf and ldap. I started of with a fresh RH7.2 installation. I ran the openldap migration scripts. Then created users using the posixAccout and posixGroup class. These classes seem to be different from what is recommended in the LDAPUserFolder product. Anyway, I have added an LDAPUserFolder, and I am able to add new new users, browse users, add groups (LDAPUserFolder cannot handle posixGroups). What I can't do though, is login using this info. If I from the management page in LDAPUserolder changes password, the encryption will change from the current Crypt, to SHA. When it is SHA, I cannot login on using pam. But even if I have sha, logging in via LDAPUserFolder still doesn't work. So, does anyone have a clue of whats going on? :) I haven't used ldap before, so it might just be me doing something stupid... all I want is an ldap database, using classes that work both in zope and with pam. /Magnus

PathIndex
by brian.r.brinegar.1 21 Nov '01

21 Nov '01

The search method of PathIndex class returns varying types depending on the success of the search. If the search fails a list object is returned, if the search succeeds an object of type BTrees.IIBTree.IISet is returned. This causes a problem in _apply_index in PathIndex when PathIndex tries to do either a union or intersection. I am doing a search of a catalog like this: catalog.searchResults(path=['/folder1','/folder2']) This should return all objects in the catalog that are inside of folder1 or folder2 and works perfectly as long as objects from both folder1 and folder2 exist in the catalog. However if say folder2 does not exist then _apply_index tries to do a union between a list and an IISet object. This raises an invalid argument exception. I'm not 100% sure where this problem should be addressed, but a quick fix I saw was to change part of _apply_index in PathIndex from: if operator=="or": set_func = union else: set_func = intersection res = None for k in record.keys: rows = self.search(k,level) res = set_func(res, rows) To something like this: if operator=="or": set_func = union else: set_runc = intersection res = None for k in record.keys: rows = self.search(k,level) if rows == []: rows = None res = set_func(res,rows) This works since union and intersection will take None as an argument but not an empty list. I would suggest PathIndex.search be changed to return an empty IISet if it fails just to have consistancy.

compilezpy (compileall)
by Danny William Adair 21 Nov '01

21 Nov '01

Hi! I wondered if this (see subject) was totally necessary during the installation. My Zope installation seems to run fine when I delete all the *.pyc and just start it. Obviously it runs slower the first time, but that's all I can see. Is there anything essential done in there, that z2.py wouldn't invoke? tia, Danny

SearchIndex deprecation warning
by Danny William Adair 21 Nov '01

21 Nov '01

Hi! I would like to get rid of this: ---------------------------------------------------------------------------- .../lib/python/SearchIndex/__init__.py:91: Deprecation Warning: ... blah ... Please use instead the re-factored modules in Products/PluginIndexes ---------------------------------------------------------------------------- Apparently one or more of my installed (third-party) products is causing this. I don't know of any explicit use of the SearchIndex module, so I guess it is some ZCatalog function being called that's relying on it (reindex?). Does anyone know which calls cause this to happen, so I can replace them with the "proper" ones? Thanks very much in advance, Danny

Database pack error.
by Terry Kerr 21 Nov '01

21 Nov '01

Hi, I posted to zope(a)zope.org regarding this error with no useful reponse. I am running Zope-2.4.1 on linux with python2.1.1. Whenever I try to pack the database I get: Error Type: FileStorageError Error Value: The database has already been packed to a later time or no changes have been made since the last pack traceback (innermost last): File /home/zope/Zope-2.4.1-src/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /home/zope/Zope-2.4.1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/zope/Zope-2.4.1-src/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: Fake) File /home/zope/Zope-2.4.1-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/zope/Zope-2.4.1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_pack) File /home/zope/Zope-2.4.1-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_pack) File /home/zope/Zope-2.4.1-src/lib/python/App/ApplicationManager.py, line 419, in manage_pack (Object: LockableItem) File /home/zope/Zope-2.4.1-src/lib/python/ZODB/DB.py, line 535, in pack File /home/zope/Zope/lib/python/ZODB/FileStorage.py, line 1240, in pack (Object: /home/zope/instance/var/Data.fs) FileStorageError: (see above) I have tried making changes to the database, setting the system clock forward several years, and it made no difference. I also commented out the redundancy check at line 1240 in FileStorage.py and tried the pack. In that case, it was seemingly successfull, except that the DB size didn't reduce. Any ideas on how my DB was corrupted and how I can fix it?
