Apparently, something leaks file descriptors. You must find the leak: "lsof" seems to be a magic wand to analyse file descriptor problems. I did not use it myself, as it requires root privileges. But maybe, it can help you. I (without "lsof") would use "netstat" to determine whether sockets are leaked or files. For sockets, it is possible to determine the peers and get a feeling, what use makes problems. For files, I would use "fuser" (the weaker brother of "lsof") to find out which files are unexpectedly open or open by two many processes. As soon as the file is located, it would probably be clear, where to find the problem. Dieter

You need to change the DTML source... Dieter

Re: [Zope] question about searching on subobjects

Place it high in the Zope hierarchy, such that it is available by acquisition where it is needed. Use it as an index in your ZCatalog.

Re: [Zope] question about multiple search criteria

A relational database gives you SQL. For atomic field values, SQL is much more powerful than the current ZCQI (Zope Catalog Query Interface). You can combine queries over different tables, combine subqueries with and/or/not almost arbitrary, have lots of functions to be used for the query results or in the where clause. However, many relational databases do not support efficient text searches. Then, I would look for ZCatalog (if I do not get too many objects (10.000 to 100.000), or for a database system with text query support. Dieter

How to add dtml-docs to Favorites links folder within CMF?ed?
by Ausum 07 May '01

07 May '01

This is a question I've previously posted at Zope-CMF, and haven't had an answer until this moment. I'm transfering previous dtml documents and directories to CMF, and I want to enable them to be stored at the "Favorites" folders of the users. Loging and logouts seem the work this way (by modifying header&footer skins), but the addtofavorites feature don't. Is there a workaround? Is it possible to turn all those previous documents into CMF-savvy, while keeping all the standard dtml docs and methods features like direct editing? Thanks in advance, Ausum

Someone else currently has similar problems (--> mailing list archives). He found out, that delete all Z Instances from a folder removed the problem. See my answer to his problem report on how I would try to analyse the problem. Dieter

Authentication for outside users
by Sven Syld 07 May '01

07 May '01

Hello, How could I do so that only users from a certain IP address will need to authenticate - outsiders? Others - insiders - will not. If I disable anonymous access and make new role with two users - outsider and insider. But authentication window will pop up for both of them even if I leave password blank. Can I automatically authenticate in DTML? Also redirecting into login screen in standard_html_header pops into my mind. But it is ugly. And unsecure. Sven

Re: [Zope] [ANN] zshell: The Zope Shell

Has there been any work on a rich-gui editor and one that is more integrated with a HTML/XML/XHTML editor outside of just using WEBDAV with Dreamweaver or something. Something where its almost like your in the same IDE to do everything - build objects in Zope, edit web content, build html files etc.??? David Kovach dave(a)kovach.com Jon >> Has anyone else played with Boa Constructor - http://boa-constructor.sourceforge.net/ ? It's open-source, written in Python, and already has some built-in Zope-specific editing facilities (it's a Python IDE and wxPython builder). Also does some basic HTML editing functions. Seems like it has a lot of potential, specially if more Zopistas contributed their ideas? Maybe it could be combined with some of the XML-RPC editing ideas (such as http://www.xml.com/pub/a/2000/01/xmlrpc/index.html )? Just a newbie's two-pennorth! :-) Cheers, Jon
