Hi all, I wanted to pack a database (27 Megs) that has never been packed before. I got this error message and traceback. Can anyone enlighten me as to what's going on? Tone

ZODB thrashing: thousands of instances in a single folder
by Darran Edmundson 09 Feb '00

09 Feb '00

I have created an AcademicPublication product which consists of a folderish container class and then catalog-aware classes for journals, conference proceedings, books, etc. Since we only expect to have a few thousand entries that don't change that frequently, I went for this option over keeping the data in a backend DB accessed via ZSQL. It works beautifully except for one annoyance that transcends my specific example. If someone with management access accidentally "clicks" on the container folder, Zope spends ages building a right-pane management view of all umpteen thousand instances. In the same way that ZCatalog displays only a select number of instances at one time, I wonder if something similar should not be added to the regular folder view? Cheers, Darran.

Reading Cookies from port 80
by James Punteney 09 Feb '00

09 Feb '00

I am trying to read some cookies that are set from the apache webserver running on port 80 (using php). When I try to read these cookies from within Zope using REQUEST.cookies.keys() the cookies do not show up. The only cookies that show up are ones that specify port 8080 within the cookie file. Is it possible to read the cookies that just have the domain name and not the port number within the cookie file from Zope? Thanks, --James

Help - ZClass instances broken!
by James W. Howe 09 Feb '00

09 Feb '00

In an effort to get a better understanding of how the XMLDocument product worked, I attempted to use the Python debugger to walk through the code. I added an "import pdb" to the build.py file and added a pdb.set_trace() to one of the methods. I started Zope from the command line with a batch file (I'm running under NT). I was able to step into the debugger and look around. The only odd thing was that some of my ZClass instances showed up as broken. I figured this had something to do with the way I started Zope so I ignored it. I then stopped Zope and reverted my build.py file back to its original state. I restarted Zope as a service (the way I usually run it). To my surprise, my ZClass instances (all belonging to the same product) were still broken! I shut everything down and rebooted my machine. I once again went into Zope and still my ZClasses were broken. The product itself looks fine. I can add new instances of my ZClasses without difficulty. However, I can't view existing ZClasses. While it wouldn't be an absolute catastrophe if I had to recreate my lost data, it wouldn't make me happy. More importantly I'm concerned that something I did broke the system, and if this were in production I would be in big trouble. Can anyone provide ideas on how I might debug and hopefully fix this problem? Thanks. James W.

Hourly restarts of Zope (sort of)
by tonyr＠ep.newtimes.com 09 Feb '00

09 Feb '00

We have brought zope up in production -- Yeah!! Now for the problem - under a load while there is still some "fine tuning" going on, we are experiencing frequent zope restarts. I know this has been a topic of discussion in the past but I was curious if anyone else has had such problems and/or what can be done to track down the culprit and correct the situation. I have tried using the How-To: Using the Zope Debug Log to Track Down Hangs with absolutely no luck. /Control_Panel/manage_debug has been as useful. We have been able to identify some long running user generated queries (ie keyword searches that brought back huge result sets) and eliminated them. But as yet have found no smoking gun as to the restarts. Does anyone out there have any ideas. Let me know what details you need. Thanks. -- ------------------------------- tonyr(a)ep.newtimes.com Director of Web Technology Newtimes Inc. -------------------------------

My suggestion (using <dtml-var id>) worked fine on my system when I searched for instances of ZClasses contained in a Folder. I wonder what's different? Maybe it depends on what base classes are used for the ZClass. James W. Howe mailto:jwh@allencreek.com Allen Creek Software, Inc. pgpkey: http://ic.net/~jwh/pgpkey.html Ann Arbor, MI 48103

Formatting Query Strings
by Guy Davis 09 Feb '00

09 Feb '00

I have seen the answer to this before, but I can't seem to find it now. (Mailing list search is down.) I am generating a URL for a link as follows: http://servername/file?name=<dtml-var name>&id=<dtml-var id> Now if the name is 'Bob' this works fine, but if the name is 'Bob Johnson' the space breaks it. There is a function to encode such a string with the correct hex in place of spaces. What is it? Thanks. -- Guy Davis mailto:davis@arc.ab.ca (403) 210-5334 Alberta Research Council

WebDav & IE5 webfolders
by Chip Vanek 09 Feb '00

09 Feb '00

Hi All, Does anyone know how to use Internet Explorer 5 Webfolders with Zope? I can see all the objects in Zope when I create a WebFolder and use my authenicated logon but, get an error when I try to post a document to a folder. WebFolders seems to want to have FrontPage extensions installed on the server. Is there a simple configuration option to allow the Zope WebDAV server to support WebFolders? Thanks for any leads. Best, Chip Vanek e-Mail: chip(a)upcast.com
