Is there any way to confirm that the hotfix has been installed? I extracted the files and restarted Zope but it would be nice if there was a way to confirm that it is installed.

Containment or context
by Stephen Harrison 16 Jun '00

16 Jun '00

Hi, I've been trying to piece together a site which exploites acquisition, but I have come up against a problem. This basically boils down to the chosen method for acquisiton. I can have a site with the following structure: / +- foo | +- stuff | +- etc... +- bar | +- more stuff | +- etc... +- baz +- and so on where foo, bar and baz are folder objects, which contain various methods, etc. Now, I can construct urls such as: /foo /bar /baz /foo/baz /bar/baz ... and in each of these the child will operate within the context of the parent. At least that is how I would like it to work. But, having read the AcquisitionAlgebra, http://www.zope.org/Members/jim/Info/IPC8/AcquisitionAlgebra/siframes.htm and a post to the list a while back, http://zope.nipltd.com/public/lists/zope-archive.nsf/ByKey/4C6995D8A903E711 I have learnt that acquisition works on the principle of containment before context. Unfortunately this is exactly what I don't want. I want context before containment, because that is the whole reason that I am construction urls in this way. The only reason that foo, bar and baz are all contained in / is so that they will all be available within the context of each other (the wonders of acquisition), but once they have been acquired, the context is all-important. Imaging that baz produces a set of data. Imagine also that within the context of foo or bar only certain subsets of baz's data are relevant. So I could go to /baz and see all the data, or /foo/baz and see only the data relevant to foo. But because of "containment before context", if I have a property as an atribute of foo to let baz know which data is important, baz will ignore it, because there is a property as an attribute of / to define the global case, which baz will use. Why is this? In http://www.zope.org/Members/Hoekstra/ChangingContexts1 it states that PARENTS is defined as the acquisition parents of an object. But this is not true. The acquisition parents of baz are / alone, but if I evaluate PARENTS from the url /foo/bar/baz/foo I will get parents of foo, baz, bar, foo, /. This is inconsistent with the idea of containment before context, and yet this is, in my opinion, the more useful case. Asuming that acquisition works the way that it does and that it is right that it should work that way (although I could be missing some reason as to why that is best), is there some other way by which I can acquire properties by, effectively, the context route? Either way, any feedback would be most welcome. Cheers, Stephen -- Stephen Harrison stephen(a)nipltd.com New Information Paradigms www.nipltd.com

Problem with adding items to ZClass instance
by Ron Bickers 16 Jun '00

16 Jun '00

[Doh... I don't read messages without subjects. Here 'tis again. Sorry.] Howdy all, I discovered something bizarre that happens in my 2.1.4 and 2.2b1 installations. I have a ZClass based on ObjectManager. In an instance of the ZClass, I can "Add" most of the available objects (DTML Documents, DTML Methods, User Folder, MailHost to name a few). However, for at least two items (TinyTable and ZMySQL DB Connection), when I add them, they show up in the container folder, not in the ZClass instance. Then, if I check it to delete it, it gives a "does not exist" error. Upon refreshing the container folder, the item still shows, but then I *can* delete it. Equally interesting is that I can Copy the item from the container folder and successfully Paste it into the ZClass instance. However, since ZMySQL DB Connections don't support Copy/Paste, that won't work. What's going on? Is it a problem with my ZClass, the Product manage_add, or Zope? Or me? _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

Updated security alert
by Brian Lloyd 16 Jun '00

16 Jun '00

Hi all - I've updated the security alert (below). Short story: a new "hotfix product" is available on zope.org that will work for all 2.0+ Zopes and has no side effects or upgrade implications for Zope installations. This feels like a much better model for things like this, especially for production sites. ---------------------------------------------------------------- We have recently become aware of an important security issue that affects all released Zope versions including the recent 2.2 beta 1 release. The issue involves an inadequately protected method in one of the base classes in the DocumentTemplate package that could allow the contents of DTMLDocuments or DTMLMethods to be changed remotely or through DTML code without forcing proper user authorization. A hotfix for this issue in the form of an add-on Zope product has been made available on zope.org. To install the hotfix, simply download and install the package as you would any other Zope add-on product (extract it in the root of your Zope installation). Remember to restart your Zope installation for the hotfix to take effect. http://www.zope.org/Products/Zope/Hotfix_06_16_2000/Hotfix_06_16_2000.tg z The hotfix will work for all versions of Zope 2.0 and higher, including the recent 2.2 alpha and beta releases. The forthcoming Zope 2.2 beta 2 release will contain a fix for this issue, and you be able to uninstall the hot fix after upgrading to 2.2. (though nothing bad will happen if you don't uninstall it). Note that the 2.1.7 release that was initially made to address this issue has been pulled in favor of this hotfix product, which will allow managers of Zope sites to address this issue without worrying about other implications of upgrading their installations. While we know of no instances of this issue being used to exploit a site, we *highly* recommend that any Zope site that is accessible by untrusted clients install the 06/16/2000 hotfix product immediately.

Problems using zope as a xml-rpc server
by Juan Carlos Coruña 16 Jun '00

16 Jun '00

Hello Zopistas, I'm trying to implement a xml-rpc server with zope. If I try to retrieve a default index_html from python with xmlrpclib there is no problem, but if I try to retrieve a dtml method with a zsql method inside it responds: xmlrpclib.ProtocolError: <ProtocolError for ntserver:8080/RPC2: 401 Unauthorized>. I test the BasicAuthTransport class from the XML-RPC How To, but it crashes with error: NameError: encodestring. After this I changed encodestring with base64.encodestring, the same result (Unauthorized). Any ideas? Thanks in advance.
