CopySupport bug or feature?
by Geoff Davis 08 Aug '05

08 Aug '05

I have been developing some classes that need to know when they are copied or moved. I have been achieving this by adding my own versions of _notifyOfCopyTo, _postCopy, and manage_afterClone. Everything works as expected when you copy / paste an individual object. However, I have recently been made aware of a problem with this approach: if you copy not the object itself, but rather a folder containing the object, only manage_afterClone is called. In looking through OFS/CopySupport.py and OFS/ObjectManager.py, I discovered the source of the problem: manage_afterClone is called recursively on ObjectManagers, but _notifyOfCopyTo and _postCopy are not. Is this intentional? If not, I'd like to check in a fix. Geoff

Zope 2.8.1 final
by Andreas Jung 07 Aug '05

07 Aug '05

Heads up for the upcoming Zope 2.8.1 final release. I will cut the release on Thursday this week. This will be - as the name says - the final release so there won't be any further beta releases. So fixes and whatever must be commited before Thursday. Depending on the number of fixes that will happen after the 2.8.1 release I will focus on a 2.8.2 release in mid-October (after a longer vacation :-)). Cheers, Andreas

Make objectValues return a generator?
by Petri Savolainen 05 Aug '05

05 Aug '05

Am I right in assuming that calls to objectValues etc. still return a real sequence of objects loaded in memory from ZODB? How about making object* calls return a generator instead? Has this been discussed somewhere already? I tried a bit of googling & list-searching but could not find much anything on this. Thanks, Petri

Username/userid separation
by Leonardo Rochael Almeida 04 Aug '05

04 Aug '05

Hi, I've started the lra-userid_username_separation-branch (from Zope-2_8-branch to start from a stable point) in order to implement proper userid/username separation in Zope. I don't intend to change the default user folder implementation, just the ZMI interface for owner and local roles so that they keep using userid for storage like they currently do but use usernames for display (specifically acl_users.getUserById(id).getUserName()). The intent is to never leak the userid to the ZMI (except for url query strings and such), and to never store the username persistently. The motivating usecase is an LDAP (eDirectory) authenticated system where the username for a user can change, but not the internal ID (a string). This will also help ActiveDirectory integration, which also has an internal ID to reference users. I remember there being a discussion about this in the list archives, but a Google search didn't help much. Are there any other projects in this area that I should colaborate with instead of duplicating efforts? Are there any considerations I should be aware of? Is the "Proposals" wiki pages still used for this kind of change? Cheers, Leo -- Leonardo Rochael Almeida <leo(a)enfoldsystems.com> Enfold Systems

File System Directory Files Permission Setting
by Evrim Ozcelik 03 Aug '05

03 Aug '05

Is there a way to set zope permissions for files that are linked to zope with file system directory view. For example, i have a zope python script which must only be executed by users that have manager role. In order to do this i think i have 2 alternatives: 1- I can control the permission in the zope python script script user = getAuthenticatedUser() if(user has manager role): .... else: go to login 2- I can put a special file like .metadata file and set the python script zope permissions. (I don't know how can i do this) Thanks,

last minute Zope 2.8.1 changes
by yuppie 02 Aug '05

02 Aug '05

Hi! If there are no objections, I'd like to merge two changes into the Zope-2_8-branch before 2.8.1 is released: 1.) Backports from zope.tal to TAL and a small modification of ustr: http://svn.zope.org/?rev=37613&view=rev http://svn.zope.org/?rev=37614&view=rev This is a fix needed by Five to handle massageIDs correctly. I don't expect any backwards compatibility issues. 2.) Backport of Interfaces.bridge from the Zope trunk: http://svn.zope.org/?rev=33270&view=rev This is a new utility function for z2 -> z3 interface migration. It doesn't change any existing code, so there should be no risk. I guess it would be useful for many products, at least CMF trunk could benefit from that bridging code. Any comments? Cheers, Yuppie

Hi, I have a stange problem that I can't solve : I work on Suse 9.0, Zope 2.7.6, Plone 2.0.5 and ZMySQLDA 2.0.8 (+mysql module 1.2.0). When I start my zope server with ./runzope : my database connections on my Mysql Server are opened correctly but when I start with ./zopectl start, the connections are closed and I can't open them manually too. When I start with zopectl , and I tried to open a connector , Zope say me: Site Error An error was encountered while publishing this resource. OperationalError Sorry, a site error occurred. Traceback (innermost last): * Module ZPublisher.Publish, line 175, in publish_module_standard * Module Products.PlacelessTranslationService.PatchStringIO, line 51, in new_publish * Module ZPublisher.Publish, line 132, in publish * Module Zope.App.startup, line 204, in zpublisher_exception_hook * Module ZPublisher.Publish, line 101, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.ZRDB.Connection, line 163, in manage_open_connection * Module Products.ZMySQLDA.DA, line 126, in connect * Module Products.ZMySQLDA.db, line 186, in __init__ OperationalError: (1044, "Access denied for user: '@localhost' to database 'usr_web1_1'") (Also, an error occurred while attempting to render the standard error message.)

For more detailed information about the error, please refer to error log. If the error persists please contact the site maintainer. Thank you for your patience. But Not when I use runzope script. and the string connection is ok too. Anybody have a idea for solve my problem ? Thanks for all Eric Brun Pentila

At: http://www.zope.org/Wikis/DevSite/Proposals/Zope3ProtectionInZope2 Is a proposal to use Zope 3's protection system in Zope 2. I think that the proposed change would provide very significan't benefits, although it also presents some risks. I'm looking for volunteers to help make this happen, peferably this fall.
