You could provide BOBO_REALM in a PCGI file directive: BOBO_REALM=spam In the next release, you'll also be able to supply environment variables on the serve.py command line.

- undefined symbol
by Gregory (Grisha) Trubetskoy 09 Dec '98

09 Dec '98

Any ideas on where I should start looking for this problem? Upon trying to look at /manage page: ImportError: ./Acquisition.so: undefined symbol: _Py_NoneStruct This happens when I try to run Zope with Httpdapy on Linux. It worked fine on my Solaris machine... Both are Python 1.5.1 and Apache 1.3.3 compiled with pretty much same options. Is Acquisition.so linked with python libraries, and where does it look for Python libs during compile? Thanks, Grisha

Re: [Zope] - How do I change the name of the / icon

The docs do not say how > the hypothetical user set his site name. First, there is really not much of a notion of a site name in Zope. To the degree that there is a site name, it is defined to be the suffix of the URL, following the host name, used to access the site. For the ZopeHTTPServer, this is an empty string. What would you like to use the site name for? Do you simply want a better decoration for the top-level folder in the navigation pane?

I wouldn't rely too much on the state-full-ness of FTP. Many FTP tools tear-down FTP connections after a period of time and reestablish them as needed. You wouldn't want your application/editing sematics to be dictated by some tool like ange-ftp. > As for choosing between implicit or explicit, how about have it both > ways? That is, have a knob in the Zope GUI that lets you set how FTP > transactions should work on a folder? Possibly, although I think that sessions would provide a more direct way to control this. I'm planning to add a feature to sessions that would allow sessions to be turned on by traversing them, rather than with cookies. For example, suppose you have a folder, F, containing a document, D, and a session S. Doing an FTP put to: F/D whould modify the document directly, but doing a put to: F/S/D would make the modification in a session. Actually, (undocumented sigh) Draft objects do this now. In fact, you could use a Draft object disable FTP access except in sessions. Jim -- Jim Fulton mailto:jim@digicool.com Technical Director (540) 371-6909 Python Powered!

Hello, I would like anyone who is interested to look at the document: http://icebox.dlogue.net:8998/Zope/ and please review it and comment. Send comments to me (mike(a)icebox.dlogue.net) I am looking for comments on any aspects. I expect there will be errors and Jim will have to wave the dead chicken over the section on Acquisition before even I would believe it. Michel

I agree, but I use slighly different jargon that reflects my different viewpoint. URL's point to *objects*. Objects may have multiple parts, which may be simple properties, sich as strings and numbers, methods, whose role is to manage or present object information, or complex subobjects. > Versioning issues: > Almost every document management system is required to have a > versioning mechanism, whereby old versions of documents can be > referenced and extracted.

I think there needs to be a way of more easily defining new kinds of objects in Zope. Zope can't really know when a change to a folder is meaningful for your application. But if you could implement your own application objects, using Zope building blocks like folders, documents, etc, then you could control what information was used for determining things like "modification time". You could also provide management interfaces that make ir easier for your customers to manage your objects. A fairly high priority for me is to come up with a through-the-web Zope class system that would make it pretty easy for you to implement the sorts of "multi-part" documents you want.

- Authenication problems when on webhost?
by Jimmie Houchin 08 Dec '98

08 Dec '98

I haven't installed Zope yet. I have been reading the documentation and posts here. There have been a couple of post by Michael Grinder which have not been answered and concern me. Maybe they have not been answered because there isn't a good solution. If that is the case I prefer to know. For those of us who have to use a webhosting service we are at the mercy of what they (the webhost) will permit and what is required configuration wise by Zope. Are there any options for configuring for Authorization that can be done by those of us who use a webhosting service? Any help appreciated. Thanks. Jimmie Houchin Michael's messages below.
