Security announcement
by Laurence Rowe 22 Jun '11

22 Jun '11

On behalf of the Plone and Zope Security Teams I'd like to draw your attention to a security announcement that has just been published. This is a pre-announcement only, it does not contain any vulnerability details. Your sites are a safe today as they were yesterday. However, as the problem that has been found is so serious we are giving you advance warning that a patch is upcoming and recommending that you plan a maintenance period for your sites to coincide with the full announcement on Tuesday next week. Full details are available at http://plone.org/products/plone/security/advisories/pre-announcement-201106… You can feel free to ask more questions on the plone-users mailing list or in the #plone IRC channel about details and how to protect yourself, but it is important to make a plan for this now. It is important to plan down-time at the time specified in that announcement or your site will potentially be at risk - following the release of a hotfix for the previous serious security vulnerability we received reports of automated attacks on unpatched sites.

Migrating a legacy Zope2 app to use buildout.
by Jason J. W. Williams 21 Jun '11

21 Jun '11

Hello, Currently, we have a Portal that was built starting in 2004 before buildout was available, so our development method has been to export and import from the Zope2 WebUI for deployment. That's been a real pain and since we've automated the rest of our infrastructure with Chef we'd like to be able to do that with Zope. So my question is does anyone have pointers for migrating an app that mostly lives in the ZODB to a build-out style architecture that we could control with Chef? I see tutorials on starting a new Zope 2 app from scratch with buildout but nothing on migrating an older one to build out. For example, how would we create objects like MySQLUserFolders etc from buildout? Thank you in advance. -J

Deploying Zope2 w/ Chef or Puppet
by Jason J. W. Williams 16 Jun '11

16 Jun '11

Does anyone have experience deploying Zope 2 services with Chef (or Puppet)? My main question is around how you're deploying an app inside ZODB in an automated fashion? I've looked at the Zenoss cookbook but it relies on Zenoss's CLI utilities that provide an interface for ZODB. -J

Securly storing variables without session in zope
by Jibin K.J 14 Jun '11

14 Jun '11

Hi, I want to store values in variables to access form another page(a.k.a State management). Now I cannot use sessions since I have multiple Zope instances & if one fails the user need to be redirected to another Zope instance and one session is valid only for one Zope instance. Now my remaining options are 1)submit a Hidden input tag using POST method 2)Passing through URL with GET method 3)Using cookies 4)Using Database(which i think is 'making simple things complex'.) I am not even considering the first 2 methods and I think using cookies is not secure. So is there a commercial or open source module that can securely(encryption etc) do cookie Management. if not I will have to use database. Please inform me,if I am missing something. Version - Zope 2.11.1 Regards Jibin

About clock-server
by Oliver 14 Jun '11

14 Jun '11

Hi, I'm using clock-server in zope.conf for running scripts periodically. The problem that I have, it uses the hour of starting of zope ... and I want it uses the hour of local server (it runs under Windows). If I restart zope, it will have initial hour again ... and I want the it runs the scripts using windows time and not hour of zope restarting. Is it possible? Or I will have to use schedule task of Windows :-? Thanks beforehand. Cheers...

2.13 upgrade problems
by Peter Bengtsson 03 Jun '11

03 Jun '11

I'm getting the error below when trying to boot up a zope 2.13.7 using a Data.fs I took from a zope 2.8.12 instance. Having Products.ZSQLMethods-2.13.3 installed or not installed doesn't appear to be relevant. The fortunate thing, in this instance, is that the SQLMethods in that instance are not important to me so I'd be happy to delete them if I could. However, I tried with ./bin/zopectl debug >>> del app.www['id_of_a_zsql_method'] but that raises the same TypeError. Any ideas? 2011-06-03 11:36:27 ERROR ZODB.Connection Couldn't load state for 0x5528 Traceback (most recent call last): File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/Connection.py", line 856, in setstate self._setstate(obj) File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/Connection.py", line 910, in _setstate self._reader.setGhostState(obj, p) File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/serialize.py", line 612, in setGhostState state = self.getState(pickle) File "/Users/peterbe/dev/ZOPE/Zope2-2.13.7/eggs/ZODB3-3.10.2-py2.6-macosx-10.4-x86_64.egg/ZODB/serialize.py", line 605, in getState return unpickler.load() TypeError: ('argument list must be a tuple', <class 'Shared.DC.ZRDB.DA.SQL'>, None) -- Peter Bengtsson, home www.peterbe.com fun donecal.com work www.mozilla.com

zope 2.11.4 + zmysqlda
by Oliver 03 Jun '11

03 Jun '11

Hi, I'm trying configure zope 2.11.4 + zmysqlda under Windows, for connecting it to a mysql database. I've done the next: 1) With zope stopped, I've downloaded zmysqlda, the last version 2.0.8, and I copy it to ""C:\Zope\2.11.4\Zope\lib\ python\Products". It's a dir named "ZMySQLDA". 2) It needs for woking mysql-python, so I've downloaded the last version 1.2.2, as windows binary, of " http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/", the file named MySQL-python-1.2.2.win32-py2.4.exe. It needs a python registered in the windows registry, and the python of zope is not registered in the installation, so I've added a manual entry in the registry: HKLM\Software\python\pythoncore\2.4\InstallPath, here I put a entry as reg_sz type with the value: "C:\Zope\2.11.4\Python\" It works well ... For testing it, I go the zope python shell and I put: import _mysql, it doesn't show error ... 3) I start zope service, but when I go to the dropdown "Add" in zope root folder, I don't have Z Mysql ... What I do bad? I have another products working well, as Ldapuserfolder, for example. Thanks beforehand. Cheers... <http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL…>

Strange Cut/Paste or Copy/Paste or Import/Export behavior
by Dragos Chirila 01 Jun '11

01 Jun '11

Hi all, I have to containers old_container and new_container that accept objects of the same type. The two containers are actually instances of different classes in the same product. I want to move all the objects from old_container to new_container. I have tried with only one object: 1. To move it with a simple Cut/Paste operation through ZMI: the object is moved successfully, but has missing properties 2. I have used Import/Export to move the same object: the object is imported successfully, but also has missing properties 3. Even tried a simple Copy/Paste: same result, no errors but missing properties Basically, the code for the object to be moved is like this: class Country(Discussion, Folder): _properties = ( Discussion._properties + ( {'id': 'body', 'type': 'text', 'mode': 'w'}, ) ) def __init__(self, id, title, body, comments, flg_notify): self.id = id self.title = title self.body = body Discussion.__dict__['__init__'](self, comments, flg_notify) def check_properties(self): """ """ print hasattr(self, 'body') print hasattr(self, 'comments') and class Discussion: _properties = ( ( {'id': 'comments', 'type': 'int', 'mode': 'w'}, {'id': 'flg_notify', 'type': 'int', 'mode': 'w'}, ) ) def __init__(self, comments, flg_notify): self.comments = comments self.flg_notify = flg_notify If i run the method check_properties before move/copy/import it prints True+True. After step 1/2/3 the result is True+False. So the missing property is 'comments', that comes from the extended class Discussion. If a I trie to acces the Propeties tab, manage_propertiesForm method, I get: Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module Shared.DC.Scripts.Bindings, line 313, in __call__ Module Shared.DC.Scripts.Bindings, line 350, in _bindAndExec Module App.special_dtml, line 178, in _exec Module DocumentTemplate.DT_In, line 703, in renderwob Module DocumentTemplate.DT_Let, line 76, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: id Module <string>, line 0, in ? Module OFS.PropertyManager, line 151, in getProperty AttributeError: comments Am I doing something wrong? Any idea is highly appreciated.
