ZPatterns 0.4.3 final for Zope 2.3.x released
by Phillip J. Eby 24 Jun '01

24 Jun '01

FYI, I have uploaded a release version of ZPatterns 0.4.3 to: http://www.zope.org/Members/pje/ZPatterns I have also updated the standalone PlugIns package at: http://www.zope.org/Members/pje/PlugIns These are primarily maintenance releases for GUI and security compatibility with Zope 2.3.x. The main added features are a 'DEPENDENT ON' clause for SkinScript 'WITH...COMPUTE' declarations, and support for the enhanced Zope 2.3 BTrees. Note that Zope 2.3.3 or better is required for either release. You do not need to download the seperate PlugIns release unless you are using PlugIns without ZPatterns, as the ZPatterns package already includes a copy of the PlugIns library. Please report any problems or concerns to the ZPatterns list, ZPatterns(a)eby-sarna.com (go to http://www.eby-sarna.com/mailman/listinfo/ZPatterns to subscribe). Thanks!

by Erik Enge 24 Jun '01

24 Jun '01

Hi, is it me, or is this just not working: (word1 or word*) and (wor?3) ie. wildcards in TextIndex queries. I can't seem to make it work, and I'm not able to track down where it stops working. Should it work in the first place? Zope 2.3.2 Thanks.

[BUG+PATCH] for OFS/CopySupport.py Zope-2.3.3
by Jerome Alet 24 Jun '01

24 Jun '01

Hi, not sure if this is the right place to post patches, but since I've already put this one into the Collector months (year ?) ago without it being applied... the method manage_renameObjects in lib/python/OFS/CopySupport.py doesn't accept to rename an objet to the same id, it's fine. however, say you want to rename the objects A and B to respectively B and A using this method, it raises an error because B already exists. a solution to this is to make the rename in two parts, and here's the patch, which seems to work fine for the not too many tests I've done: --- CUT--- --- CopySupport.py Mon Apr 16 18:26:20 2001 +++ CopySupport.py.new Sun Jun 24 20:58:48 2001 @@ -281,9 +281,20 @@ """Rename several sub-objects""" if len(ids) != len(new_ids): raise 'Bad Request','Please rename each listed object.' + conflicts = [] for i in range(len(ids)): if ids[i] != new_ids[i]: + if new_ids[i] not in ids : # may a conflict occur ? self.manage_renameObject(ids[i], new_ids[i], REQUEST) + else : + tempo = ".temporary_%i_" % i + self.manage_renameObject(ids[i], tempo) + conflicts.append((tempo, new_ids[i])) + + # now we rename conflictuous objects + for (old, new) in conflicts : + self.manage_renameObject(old, new) + if REQUEST is not None: return self.manage_main(self, REQUEST, update_menu=1) return None --- CUT --- NB: a better temporary id should be created. hoping this helps. bye, Jerome Alet

ZPL and GPL licensing issues
by Morten W. Petersen 24 Jun '01

24 Jun '01

Hi there, we @ thingamy are considering changing our license to a ZPL-ish one [1] to better serve our clients' needs. However, some of the (Zope) products we've developed may need to rely on GPL'ed code, or needs to be incorporated within it, and the 'obnoxious advertising clause' seemingly puts a stop to it.. The ZPL is listed as a license incompatible with the GPL, but it doesn't really say clearly what the reason is, as far as we can figure, it's because of the advertising clause. Anyways, I'm wondering if any of you have encountered the same issue developing Zope products and any solutions towards it. Some interesting articles, food for thought: http://www.zdnet.com/enterprise/stories/main/0,10228,2777053,00.html http://www.gnu.org/philosophy/license-list.html#GPLIncompatibleLicenses http://www.gnu.org/philosophy/bsd.html [1] http://www.thingamy.com/tpl Regards, Morten

Re: command-line zope.org product upload ?

Hey, uh, me and the folks on the list think there's this > one little extra that would make zshell perfect.. :) Sorry for being late, I hadn't yet subscribed to this list. I'd love to do this, however it seems to be very difficult until a standard Zope package file format exists. See my posts on this subject on zope(a)zope.org However I think a "shell" command could help, e.g. in ZShell dialog box you'd type something like: shell apt-get update shell apt-get upgrade This would do it, but you'll need to have an apt-get wrapper which would have to be setuid root, so this would be very dangerous. the best solution is of course to standardize on one file format, and tweak Distutils to do what we want, then adding "zope-apt-get" to ZShell (or why not directly to Zope) will be trivial. bye, Jerome Alet

what to return for a manage_edit method
by Sin Hang Kin 23 Jun '01

23 Jun '01

What should I return to for a method that create a new object or modify the object? If I return a redirection, will it too restricted for web only? If I return a simple ok, it seems very stupid. Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net

making zwikiwebs.zexp import unnecessary
by Simon Michael 23 Jun '01

23 Jun '01

I think I read someone had integrated the sample zwiki web(s) into the python product, removing the need for the import which causes great confusion. If you know anything about this, please get in touch. Thanks -Simon

Fishbowl not problem centered enough
by Jay, Dylan 23 Jun '01

23 Jun '01

Fishbowl is a great idea but it seems to be that its solution focused rather than problem focus. Perhaps if you had a page that listed all the problems with zope or problems that need to be solved that isn't as easy as it could be with zope. Problems could then be organized according to priority due to severity or strategy, or even voting via the comunity (ala Java bug parade developer.java.sun.com/developer/bugParade/) Then under each problem could be listed the proposals that form solutions to the problem. Of course some solutions may solve many problems and therefore appear more than once. I just see lots of solutions many of which attack some of the same problems and no clear way to get those people comunicating and making informed trade-offs ---- Dylan Jay mailto:djay@avaya.com Avaya Communication Tel: +61 2 9886-8961 Level 3, 123 Epping Road FAX: +61 2 9352 9224 Nth Ryde NSW 2113 Mobile: 0409 606 171 AUSTRALIA

default roles in ac_permissions
by John Eikenberry 22 Jun '01

22 Jun '01

Note: I'm still using Zope 2.2.5, which is why I'm forced to use __ac_permissions__ and not the new security code in 2.3.x. In the documentation I've found on how __ac_permissions__ works you are supposed to be able to set default roles for a permission in a 3rd tuple. I've tried various things and can never seem to get them to take effect. The acquired permissions always take precedence. The only thing I can think of to do is create a method that I can call to set them using the builtin methods (eg. manage_changePermissions). Has anyone had any sucess with default roles in the __ac_permissions__? If so how, if not what did you do to automatically set default roles for a product? Thanks in advance for any info. -- John Eikenberry [jae(a)kavi.com] ______________________________________________________________ "A society that will trade a little liberty for a little order will deserve neither and lose both." --B.
