Broken ZDiscussions-0.5.3 on 2.2.1b1: missing comma...
by J M Cerqueira Esteves 21 Aug '00

21 Aug '00

I tried to install ZDiscussions (ZUBB) 0.5.3 it on a Zope 2.2.1b1 and got a broken product. The traceback I got at Zope startup was: 2000-08-21T01:44:09 ERROR(200) Zope Couldn't import Products.ZDBase Traceback (innermost last): File /usr/local/lib/Zope-2.2.1b1/lib/python/OFS/Application.py, line 396, in import_products (Object: string) File /var/lib/zope/an/Products/ZDBase/__init__.py, line 86, in ? File /var/lib/zope/an/Products/ZDBase/ZDiscussions.py, line 106, in ? File /usr/local/lib/Zope-2.2.1b1/lib/python/App/class_init.py, line 109, in default__class_init__ (Object: ZDItem) File /usr/local/lib/Zope-2.2.1b1/lib/python/AccessControl/Permission.py, line 204, in registerPermissions ValueError: unpack sequence of wrong size The problem seems to be a missing comma in the definition of__ac_permissions__ in class ZDItem (file ZDiscussions.py): __ac_permissions__ = ( ('Manage properties', ('manage_addProperty', 'manage_editProperties', 'manage_delProperties', 'manage_changeProperties',)) ) Since this is lacking a comma before the last parenthesis, outer parentheses are "dropped" and it becomes as a two-element tuple: ((X,methods)) -> (X,methods) that is, a "naked" permission, instead of the intended one-element (one permission) tuple ((X,methods),). In fact, ac_permissions_ was already defined like this in ZDiscussions-0.2.0... I wonder if this was clearly noticed before 2.2.1b1, since line 204 of Permission.py (see traceback above) belongs to a new function called `registerPermissions'. This function begins with for setting in permissions: if _registerdPermission(setting[0]): continue if len(setting)==2: perm, methods = setting default = defaultDefault else: perm, methods, default = setting _registeredPermissions[perm]=1 and with the bug above, its easy to see the mess resulting when `permissions' has the above __ac_permissions__ value. Apart from this, is ZDiscussions (ZUBB) 0.5.3 fully compatible with Zope 2.2.1? I just restarted Zope after adding the comma and the product is no longer broken. Perhaps I can do some testing now...

ZCatalog and Traversable questions
by Chris Withers 21 Aug '00

21 Aug '00

Hi :-) 1. Are the paths you supply to catalog_object() supposed to start with a '/'? I think they should but I'd like some sort of confirmation :S 2. Why isn't there a Traversal Interface method to allow you to actually get the physical path of an object? (for use in cataloging them, for example ;-) I'd assumed getPhysicalPath() would do this but I see it returns a tuple :( Any ideas? cheers, Chris

Several times I've considered re-writing the tree tag from scratch since the cookie-state thing often seems to break down unless used in simple circumstances and the code in Treetag.py does seem a bit of a crufty mess (branches, branches expr, having to specify expr instead of just using "", no _ in expr, state in cookies (which can really go badly wrong :S), hard coded formatting of trees, etc) but the last time I put it off because I thought a major overhaul of DTML was imminent. (in that instance, I just used an external method to generate my tree since it was quicker and easier than making dtml-tree behave like I wanted...) I still think DTML needs a major overhaul but there seems to be a lot of resitence to this (maybe rightly so?) Perhaps it's time to just redo the tree tag in isolation then? What do people think? cheers, Chris

Unable to resolve 'Uncatalog...' error with PTK
by David Riggs 21 Aug '00

21 Aug '00

Having still more problems with this installation of Zope 2.1.6 and PTK 0.7.1... I've got several (seems that the number is growing) objects that appear in my ZCatalog, and show up on my site, but refuse to let me edit, move or delete them. Try to delete the object and get the following error: ------------------------------------------------------------------------------------------------------------------- Error Type: ValueError Error Value: Uncatalog of absent id '/portal/Members/demo4/D_Application' Traceback (innermost last): File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 214, in publish_module File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 179, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\Zope\__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 165, in publish File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\ZPublisher\Publish.py, line 102, in call_object (Object: manage_delObjects) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 401, in manage_delObjects (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\OFS\ObjectManager.py, line 273, in _delObject (Object: ElementWithAttributes) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 226, in manage_beforeDelete (Object: D_Application) File C:\Program Files\dev_portal\lib\python\Products\PTKBase\PortalContent.py, line 213, in unindex_object (Object: D_Application) File C:\PROGRA~1\DEV_PO~1\lib\python\Products\ZCatalog\ZCatalog.py, line 357, in uncatalog_object (Object: ElementWithAttributes) File C:\PROGRA~1\DEV_PO~1\lib\python\Products\ZCatalog\Catalog.py, line 373, in uncatalogObject ValueError: (see above) ------------------------------------------------------------------------------------------------------- Updating the ZCatalog doesn't help, nor does clearing it out and re-populating it.

As always, any and all comments/ suggestions/ help are very much appreciated...I've found this mailing list archive to be the most helpful documentation available so far. Thanks, Dave.

Newbie's ZWiki patch
by Jean Jordaan 21 Aug '00

21 Aug '00

Hi all I've overreached myself and patched ManagedMode ZWiki (love it, by the way), 'cause I couldn't stand the tag-abuse of the annotations, involving a table with explicit border- and color- specifications, all in the face of users editing the source of zwikipages. I've changed it to:: .... .... .... Of course, this presupposes a couple of CSS specs in the 'standard_zwiki_header' or someplace .. My changes to 'ZWikiPage.py' are marked 'njj:' in the following:: ### # If edit marker hasn't already been filled in by approval activity # then append one if s <> '': # njj: this is blatantly abusing 'bgc'. I could have changed # njj: 'bgc' everywhere to, for example, 'edit_class', assigning # njj: it the values 'wiki_edit', 'wiki_approved', and # njj: 'wiki_rejected' in the first place. text = text + '\n' + s + '\n' if bgc == '#99ff66': # njj: light green = 'Approved by '. text = text + 'wiki_approved">' + s + '\n' if bgc == '#ffcc33': # njj: light red = 'Rejected by '. text = text + 'wiki_rejected">' + s + '\n' # njj: text = text + '\n<table class=mm width="100%" bgcolor=' # njj: text = text + bgc # njj: text = text + ' cellspacing="0" frame="box" border="1"><tr><td>' # njj: text = text + s + '</td></tr></table>\n' Do any of you know of anyplace this is going to break? Does anyone think it's worthy of proper integration? I don't know if legacy browser support is an overriding issue here, since Lynx and W3, for example, certainly wouldn't do any better with the table than with the CSS .. AFAIK .. -- Jean Jordaan -- technical writer -- Mosaic Sofware -- Zope 2.1.6 on WinNT and W2K
