RE: [Zope] user id naming conventions

NB - putting an '@' sign in an id is a very bad, bad, bad idea. I suppose that's pretty obvious, actually. It was ok for about an hour and then I got Zope errors complaining about the '@' in all frames of the management console. Refresh did not get me any more access to the ZODB. <dtml-var panic> I tried the browser's back button and got to a screen where I could see the object. Deleted the offending object with extreme prejudice, and things are better now. -----Original Message----- From: Joshua Lanza Sent: Wednesday, January 02, 2002 4:00 PM To: zope(a)zope.org Subject: [Zope] user id naming conventions Does anyone have any feelings on the best way to manage user id's?

Or there's always dumping the result set into an xml data island and using javascript to sort it - fairly easy to do and takes a lot of work off of the server, but only works on newer browsers. -----Original Message----- From: complaw(a)hal-pc.org [mailto:complaw@hal-pc.org] Sent: Wednesday, January 02, 2002 4:14 PM To: Lucas Vogel; zope(a)zope.org Subject: Re: [Zope] sorting a table Normally what I do is have the table header/title include a hyperlink to another Z SQL Method (one that sorts the way you want it to).

Look at the management interface. The main frame does what you are looking for. Figure out the file that generates that frame, and look at the DTML/python to see how it is done. -Scott -----Original Message----- From: Lucas Vogel [mailto:vogell@yahoo.com] Sent: Wednesday, January 02, 2002 3:09 PM To: zope(a)zope.org Subject: [Zope] sorting a table I have a DTML method that calls a Z SQL Method and places the results into an HTML table.

RE: [Zope] Zope performing poorly after adding objects to BTreeFo lder
by sean.upton＠uniontrib.com 03 Jan '02

Your problem sounds like a memory leak. I think it has to do with BTreeFolder or one of its parent classes, and not Catalog. I think there are ups and downs to BTreeFolder. BTreeFolder does well for storing lots of objects, but the ObjectManager interface that all folders use via mixin doesn't scale very well in certain respects for handling all those objects (at least that is my experience with ObjectManager._setObject(), so I instead used BTreeFolder._setOb() which yielded a HUGE performance increase; I figure the same may be true with _getObject(), etc). I would suggest familiarizing yourself with the BTree interfaces and using BTreeFolder._tree() directly. This has been my experience creating a container to store ~330,000 objects in a BTreeFolder. Of course, this bypasses security, so careful planning and development is advised. I don't think ZCatalog is your problem, as it sounds like the Catalog is not being used in certain cases (like listing objects via objectIds() or objectValues()), and you still get a problem. Personally, I wonder if BTreeFolder really needs more work to override more OM interfaces with 'native' faster versions. I'm interested in hearing other's thoughts...

Re: [Zope] Zope performing poorly after adding objects to BTreeFolder - More info

I have been running top and have the following observations. If you start Zope and just let it run, it does so quietly at about 8% of memory. If you ask it to do something, it splits into two processes (or at least two PID's) with roughtly the same memory usage (which, if you add the two, is over 100%). The box slows to a crawl, and I have to restart Zope to clear it all up. I'm using Zope 2-4-3 on Linux.

Date Formatting Oddity
by Dan Shafer 02 Jan '02

02 Jan '02

The strftime() parameters seem to allow for just about every conceivable time and date output format one could imagine. Except the one I need. Is there a format string or some other method I'm overlooking for suppressing zeros on dates from 1-9? January 02, 2002, just doesn't look right. -- Dan Shafer, Author-Consultant http://www.danshafer.com http://www.shafermedia.com
