Raw-input control for input widgets
by Jim Fulton 25 Apr '05

25 Apr '05

I'd like to have more control over input widgets. I'd like to have a way to get, set, and clear their raw input. The main use case for this is to be able to store unprocessed raw inputs: - in wizards or multi-page forms - to allow a user to leave a task and return to it later A secondary use case is to allow inputs to be cleared so that user inputs aren't displayed after a form is redisplayed after acting on previous inputs. I believe we discussed this a couple of years ago, but nothing was ever done. Thoughts? Unfortunately, I don't think we can do anything for this before 3.2.

2.8.0b1 issues with plone 2.0.5
by Tim Hicks 25 Apr '05

25 Apr '05

Apologies if this is already known about... I just installed 2.8.0b1 (using python 2.3.5), fired it up, then tried to add a 'plone site' (2.0.5). The plone site actually did get added, but here's what I got as well: 2005-04-24 12:57:32 ERROR Zope.ZCatalog Recataloging object at /test/test/index_html failed Traceback (most recent call last): File "/home/tim/zope/2.8.0b1/lib/python/Products/ZCatalog/ZCatalog.py", line 298, in refreshCatalog self.catalog_object(obj, p, pghandler=pghandler) TypeError: catalog_object() got an unexpected keyword argument 'pghandler' 2005-04-24 12:57:34 ERROR Zope.SiteErrorLog http://glenmore.dyndns.org:7080/test/test/index_html Traceback (most recent call last): File "/home/tim/zope/2.8.0b1/lib/python/ZPublisher/Publish.py", line 113, in publish request, bind=1) File "/home/tim/zope/2.8.0b1/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/home/tim/zope/2.8.0b1/lib/python/ZPublisher/Publish.py", line 40, in call_object result=apply(object,args) # Type s<cr> to step into published object.

Data manager interface -- tpc_begin and other changes
by Jim Fulton 25 Apr '05

25 Apr '05

This is for people who've implemented ZODB data managers. Data managers are components that manage persistent data under transaction control, We've recently tried to clean up and document the data-manager interfaces. In addition, over the weekend, I implemented savepoints and was able to simplify the interfaces quite a bit. See IDataManager and ISavePointDatamanager in: http://svn.zope.org/ZODB/trunk/src/transaction/interfaces.py?view=markup In particular, note that: - The subtransaction APIs have disappeared fro data managers, and - tpc_begin no longer takes a second "subtransaction" argument. I *could* try to provide support for data managers with tpc_begin taking 2 arguments, but I'm guessing that I don't need to. I'm guessing that no one has written data managers that require a second argument. If this is not true and you have a data manager that requires a second argument that I need to support, please let me know. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

BTreeFolder2 for Zope 2.8?
by Andreas Jung 25 Apr '05

25 Apr '05

Any objections to move BTreeFolder2 into the Zope core for Zope 2.8? BTF is widely used in the Zope, CMF & Plone world and it would not hurt to ship it with Zope. Andreas

I want Zope 2.9 to use Zope 3's security architecture.
by Jim Fulton 20 Apr '05

20 Apr '05

I very much want Zope 2.9 to use Zope 3's security architecture. Zope 3's security architecture is far more robust, but it is different in some significant ways: - It protects names not values. This means that you protect how you access things, not the things themselves. - It doesn't provide key-bases access control for mapping objects. If you can get any key, you can get all keys. This is less powerful that Zope 2's security system, but this is power we haven't needed for Zope 3 and I suggest we don't really need it for Zope 2. - Non-basic values passed from trusted code to untrusted code are security proxied and thus protected. This means that the security framework has a much greater reach than in Zope 2, Even trusted code is subject to the security system in many cases. This can be a good thing or a bad thing, depending on your point of view. :) - The Zope 3 security system is much more pluggable. This means that it is much easier to provide alternate security policies to meet special needs to or exclude unneeded features. For more information on the security system, see: http://svn.zope.org/Zope3/trunk/src/zope/security/untrustedinterpreter.txt?… http://svn.zope.org/Zope3/trunk/src/zope/security/README.txt?view=markup http://svn.zope.org/Zope3/trunk/src/zope/app/securitypolicy/zopepolicy.txt?… http://www.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/Programmer… I see 2 main challenges: - supporting implicit acquisition - Backward incompatibilities: o No support for key-based access control o Trusted code will be subject to security restrictions in cases in which it isn't now. I think there will be a number of significant benefits, including: - Greater security - Less complexity - Less risk with new Python versions - Narrower gap between Zope 2 and Zope 3. This will be a fairly large job. I won't have time to work on it before this Fall. I could certianly use some help. :) Are there any objections? Suggestions? Questions?

debug-mode on under Windows 2000.
by DonJFreeman＠cs.com 19 Apr '05

19 Apr '05

Zope Version: (Zope 2.7.3-0, python 2.3.4, win32) Python Version: 2.3.4 (#53, May 25 2004, 21:17:02) [MSC v.1200 32 bit (Intel)] System Platform: Windows 2000 I'm trying to get Zope to reload my Python modules so I don't have to restart Zope after code changes. Even with debug-mode on (according to the zope config file, it defaults to on) my modules are not being reloaded unless I do a restart. Is there a fix for this? Thanks, Don

Editing using Firefox
by Jeff Nielsen 16 Apr '05

16 Apr '05

Sorry in advance if this issue has been covered a bzillion times already... I'm playing with editing my Zope site using Firefox as I can open Document and Method objects in tabbed windows and switch back and forth between them. However, the tab title, based on the page title, for each object is just "Zope". Is there a way to get the object name to be used as the page title and hence the tab title? I've searched about a bit for an answer and no joy so far. Jeff Nielsen UgoFast http://www.UgoFast.com Jeff(a)UgoFast.com
