I thought this was a built-in python method, so I'm a bit puzzled. For security reasons, Zope are removed all builtin-functions from DTML expressions. You can access some of the builtin objects as attributes/methods the special variable "_". Look in the DTML reference (e.g. at URL:http://zdp.zope.org) for a list of available builtins in "_".

Luis Cortes has told you, how you could do your job. Explanation: Python distinguishes between expressions which can be "eval"ed and commands which can be "exec"ed. Assignments are commands, as are definitions, if, for, while constructs. Zope uses "eval" to evaluate expressions in DTML-tags. "eval" raises a SyntaxError when confronted with a command. Dieter

Higher Education Wiki or mailinglist

I'd be very interested in a Zope-in-education Wiki. I work in an educational institution, and I am very excited about it's potential, but don't know enough yet to go around reinventing the wheel, so to speak.. Could someone post an announcement when/if this happens? Thank you! Chris Beaumont cbeaumon(a)msri.org > > Shane, > > Thanks for the reply.

Roxen+Zope => Static+Dynamic pages
by Adrian Esteban Madrid 26 May '00

26 May '00

Is anybody using Roxen and Zope to serve both dynamic and static pages? I've seen some hacs and products to serve static pages from zope but I figure there must be a way to serve static directly from roxen instead of doing roxen-zope-roxen. Any ideas? Anybody knows how to change the redirect rules to do that? Adrian

Zope Instability
by Rob Sporleder 26 May '00

26 May '00

Hi, We recently setup a Zope server and it has been running great until this morning when it stopped responding, twice. There are no errors, core files or indication of a problem except that the server stopped responding to http requests. All processes were still running and a simple restart remedied the problem both times. Has anybody had any similar problems, advice, etc. We are running two Zope servers serving two different sites. Both servers run as the same user. Thanks, --Rob Zope Newbie

Jet is inherently thread-unsafe, and M$ has no plans to fix this (such a fix would cut into their ability to sell SQL Server). This issue has been a long-running problem in the Windows world; the only solution is to serialize *all* access to the DB (even concurrent *reads* can foul each other up -- blech!)

RE: [Zope] Medusa vs. Apache

If performance is a concern I would go with Apache. It is much more robust and faster than Medusa.

Anyone going to try? Not me. I just wanted to add that imho saving an rfc822 object (using the standard python module) might not be a bad idea. I used it for a product (using bobo that was, I changed it after ZOpe came) that eats a Netscape inbox, by way of a maillists digest. And what about an XML derivative of the rfc822? Rik

I mean, i'm not sure how the slightly >different agendas would work out... Hi Ken I have been lurking on the edu-sig for a while now. I think your concern about divergent interests is quite justified. The zope-edu list was more about getting a coherent framework in Zope, while the the edu-sig is more about teaching programming in the Computer Programming for Everyone program, even if discussions seem to be narrowing down to teaching computer math to everyone. There has been an occasional mention of ZOpe, though. If a Zope-edu effort would bring a Computer Mediated Instruction environment, this might be of great help also for them my 2 cents Rik
