Weird IndexableObjectWrapper + TopicIndex + aq_acquired interactions.
by Lennart Regebro 21 Sep '05

21 Sep '05

You know you are in trouble when you need to read the c-code of Acquisition to understand a problem. :) This took me half the day to figure out, and in fact, I still don't fully understand it. So I need help with this. CPS has an index, called cps_filter_sets. It's a TopicIndex, and TopicIndexes can have expressions as filters. This one has: "getattr(o, 'portal_type', None) not in ('Section', 'Workspace')" Where o is the object that are being indexed. But, this being an expression, it's protected, and therefore, a getattr becomes a guarded_gettatr. guarded_getattr does it's security check by doing: validate = SecurityManagement.getSecurityManager().validate aq_acquire(inst, name, aq_validate, validate) Where in this case inst will be the object that is being indexed. aq_acquire will, if the first parameter is not an AcquisitionWrapper, and the third parameter is not None, wrap the object. Now, in our case, the object is an IndexableObjectWrapper, wrapping an Acquisition wrapped object. So, aq_acquire will Acquicision wrap the IndexableObjectWrapper, with the result that the object being used now has no context! Then, it passes this to validate, who in turn passes it to allowed, who check that the object has the users user folder in it's context. And it hasn't, because it has no context. *blam* You get an AuthorizedError, and the object does not get indexed. OK, there are several ways to fix this, one being to not use getattr. But there is still something missing from my understandning of all this: - Not every object has this problem! Why, I have no idea. I had his problem in two products, and in ONE of them, it disappeared when I introduced the otherwise useless PropertyManager as a baseclass. The other product already has propertymanager as a baseclass! Any insight into this would be appreciated. //Lennart

Is there any way this could use normal python loggers? logger = getLogger('progress') ? (and then with a more generic section in zope.conf for having more loggers configured...)

RE: [Zope-dev] Installing Python Modules Under Zope On Windows
by Jason R. Coombs 16 Sep '05

16 Sep '05

You can trick the installer to using a particular instance of Python with an easy registry hack. I've done this a couple of times to use Python version specific binary installers to my Plone install. The key is in HKLM\Software\Python\PythonCore\2.x\InstallPath. The value is a REG_SZ of the fully-qualified path of the python root for that version of Python. You can change that value, run the installer(s), then change it back (at least I do, for system integrity). Jason R. Coombs -----Original Message----- From: zope-dev-bounces(a)zope.org [mailto:zope-dev-bounces@zope.org] On Behalf Of tom(a)tompurl.com Sent: 16 September, 2005 09:21 To: zope-dev(a)zope.org Subject: [Zope-dev] Installing Python Modules Under Zope On Windows I have a hardware constraint where I have to run Zope on Windows. This has worked pretty well for me because Zope 2.7 used my "system" instance of Python 2.3.x. At least, that's my assumption since runzope.bat pointed at the system instance of Python. This setup was nice because it made it very easy to install Python modules (like PIL). When I ran the module installation executable, it would find my system instance of Python in the registry and install the module properly. With Zope 2.8.1, the "default" setting seems to be using the embedded Python interpreter that came with Zope. This is a problem because the embedded versions of Python do not appear in the registry, making it impossible to install a lot of Python modules on Windows. I thought that the following script (http://effbot.org/zone/python-register.htm) would allow me to add embedded versions of Python to my registry. However, you can't add more than one major version of a python release (2.2, 2.3, etc) to the registry. So if my system version of Python is the 2.3.x branch, and I want to use an embedded 2.3.x version of Python with Zope, then I'm out of luck if I want to install many Python modules with it. I can still edit runzope.bat so that it points at the system instance of Python, but I don't know if this is a best practice. Has anyone had any luck installing Python modules in an embedded version of Python on Windows? Is there a better way to work around this than referencing the system version of Python in the runzope.bat file? Thanks in advance for any help!

Maintainer position for the Zope Windows builds vacant
by Andreas Jung 15 Sep '05

15 Sep '05

Hi, Christian Theune, the current maintainer of the windows builds, announced to step down as maintainer. This means that this position is vacant. So this is your chance to become famous :-) To be honest, doing Zope releases is a bit of work and not always fun but it is work that has to be done by someone. So if you are interested and if you have the resources, raise your finger. Since new Zope 2 releases are scheduled for October I would like to see this position filled asap. I will definitely continue on the source releases but I have not enough Windows know-how to do it myself. Since there are lot of *serious* Zope-on-Windows users I do expect that someone takes over this great job. Having no volunteer for the Windows builds would mean that only source code releases would be available in the future. I'm fine with that but possibly not all Zope-on-Windows users...so if you depend on Zope-on-Windows you should do something for your dependency to be fulfilled. Cheers, Andreas

Schedule Zope 2.8.2/2.7.8
by Andreas Jung 14 Sep '05

14 Sep '05

Hi, I plan to release Zope 2.8.2 + 2.7.8 on 12.9.2005. As discussed a while ago I will release minor releases without going through a beta cycle except when there are critical fixes that need further testing. Andreas
