Web Services for Zope
by Andy McKay 01 Oct '01

Can I ask what the current status of the WebServices for Zope project is? http://dev.zope.org/Wikis/DevSite/Projects/WebServicesForZope/FrontPage Wiki says "I had been shooting for something at the end of September, but that has been overtaken by events :( I'll be trying to work on this on an as-possible basis" trying-to-auto-generate-a-wsdl-from-my-product'ly yours -- Andy McKay.

Hia, While trying to reindex an entire catalog an error is raised, which looks like this: Traceback (innermost last): File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: api) File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: update_instances) File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: update_instances) File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/Products/WarpFramework/catalog.py, line 438, in update_instances (Object: api) File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/Products/WarpFramework/catalog.py, line 195, in __call__ (Object: Traversable) File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/Products/ZCatalog/ZCatalog.py, line 535, in searchResults (Object: Traversable) File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/Products/ZCatalog/Catalog.py, line 666, in searchResults File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/Products/ZCatalog/Catalog.py, line 614, in _indexedSearch File /home/morten/zope_instances/usr2/local/Zope-bcr/lib/python/SearchIndex/UnIndex.py, line 453, in keyForDocument KeyError: (see above) Any clues?

[Bug] DateTime(string) uses GMT as timezone
by Dieter Maurer 01 Oct '01

01 Oct '01

Unfortunately DateTime(year,month,day) != DateTime("%d-%d-%d" % (year,month,day)) The former uses the local timezone (which I think is right) while the latter uses GMT+0 (which seems not right). Thinks are quite bad, as the latter is used to convert ":date" form values into DateTime objects. Dieter

how to accept an arbitrary parameter/anti-NIMDA script
by marc lindahl 30 Sep '01

30 Sep '01

I'm looking at how to get this anti-NIMDA script to work in zope ( http://pc.xs4all.nl/default.ida) The thing is, it's called with a parameter (trying to cause a buffer overflow). For example: /default.ida?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3% u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a That site has a default.ida which will pass back a perlscript that turns off that particular machine's virus under certain cases... sounds like a good thing. But how can I get an object called default.ida to accept anything passed after the "?" and what kind of object (python script?) should it be?

Z SQL Methods appear broken in 2.4.x
by joe＠silverwolf.com 28 Sep '01

28 Sep '01

It appears that Z SQL Methods are broken in 2.4.x. Specifically, the type=string in a <dtml-sqlvar> is broken - a simple ZSQL query such as: select id, cost, name from choices where name = <dtml-sqlvar nam type=string> results in the following error: exceptions.NameError: global name 'string' is not defined It's broken on 2.4.0 and 2.4.1, and works fine on 2.2.5, 2.3.0, and 2.3.2 - in fact, it's in production on our 2.2.5. Integer parameters work fine. It's hard to believe that no one else has run into this, and that the stable 2.4.x branch has gotten this far without anyone noticing this - I've even tried it on 2 different servers running Zope 2.4 (2.4.1 on FreeBSD 4.0, our production web server, and 2.4.0 on FreeBSD 4.3, our dev server) Any ideas?

Zope 2.5: User limit for Local Security Role assignment list
by Matthew T. Kromer 28 Sep '01

28 Sep '01

One of the things Zope 2.5 is going to do is limit the answers that are available from a user folder when presenting the local role dialog; this will prevent humongous lists from displaying and instead show a simple text box where a user ID can be typed. However, for existing user folders, this poses a question of: what's the reasonable number of users to list without having to go adjust a property on the folder? The revised implementation will let you tune how many users to display before putting up an input box; but currently I've just defaulted it to 'old behavior' -- ie show all the possible users. Maybe a better thing to do would be to define a default of 250 or so. This would probably be large enough to not impact most sites, yet small enough to make it meaningful for those sites that do have enormous user folders. It is also worth pointing out that local role assignment code doesn't enforce that the users for whom it has local roles exist in any current database; it is possible to grant rights to nonexistent users. Before the ability to enter a name in directly was available, you would have had to explicitly change the form values manually -- but this exposes the problem. I dont think it poses a problem (ie I dont believe Zope has ever tried to define a mechanism whereby objects are notified that a user for whom they have permissions has been deleted.)

testing types in PythonScripts
by Steve Alexander 28 Sep '01

28 Sep '01

I have a variable, f. The value of f might be a list, or it might be a string. I want to do different things to f depending what type it is. How do I check its type from a PythonScript? I can't use type(), as this opens up a security hole with Extension Classes, where the type is the class. I can't import types, as that seems to be restricted. I suggest that either one or both of the following be altered: * The types module is allowed to be imported into restricted stuff. * A safe version of type() is put into the restricted global namespace. I seem to recall a discussion of this a few months ago, where someone (Evan?) proposed a safe version of type(). I guess this got lost in the conversion to RestrictedPython with Zope 2.4. Oh yeah... an ugly workaround is to try to append to f and see if you get and AttributeError. -- Steve Alexander Software Engineer Cat-Box limited
