That's just how I design - think about what the problem *really* needs, and then figure out how to do a scaled down version of it that's actually implementable within budget. The nice thing about this approach is that it: A) helps prevent you getting stuck further down the road, and B) often gives you a simpler way of doing things, with spin-off benefits you weren't originally looking for. Polya's Paradox states that it's often easier to create a general solution for a class of problems and then to specialize it for your specific problem, than to build a specialized solution just for your one problem. The ZPublisher concept itself is a brilliant application of this principle. >But it WAS a great post and brought up a lot of requirements >and considerations that I hadn't thought about. Well, you probably don't need/want a full-blown scheduling system like what I described, but the basic ideas of an Event, Schedule, and CalendarEntry can probably still help you with your projects. You might even leave out Schedule, since Schedules are only needed to manage resource commitments, and it sounded like that would be external to your application. Anyhow, just focus the ideas much more specifically for your application. Then, if a full-blown system ever shows up, your application is already designed in a way that would make it conceptually straightforward to port over and take advantage of the rest. There is a good chance that I or other members of my team will be tackling some of these items in the not-too-distant future, though I expect it could be quite a while before we have a robust general system. I *do* have some interest in design collaboration by fellow Zopesters, however, and I think it would be great if we could hash out the interface protocol for the different pieces and then all begin making components that work according to that API. Maybe Zope needs some SIG's along the lines of the various Python SIG's... Hmmm. :)

Unfortunately, the whole project deals with making corporate data available to our outside people and distributors. The data is in Visual FoxPro tables which I access via ODBC. Therefore, I must run on windows. I must use SSL -> must use IIS. (aaarrrggghhh!!!!)

Problems in 2.0 using ZServer ws. using IIS
by Jim Sanford 06 Sep '99

06 Sep '99

I have a project that is being developed for in house use. It will need to run under IIS in order to use SSL. We are about 2-3 weeks away from deployment. I have a problem with truncated results being sent back whenever I am routing through the pcgi wrapper under IIS. Icons do not render completely (if at all) and html pages are often truncated. I access zope with http://IP-ADDRESS/scripts/zope.cgi/... When accessing via http://IP-ADDRESS:8080/... I do not encounter these problems. An article on the Microsoft Web site claims that these types of CGI problems are caused by improperly written CGI processes runnig under IIS 4.0, which implements the CGI standards more strictly than previous versions. Additionally I seemed to be able to add a new dtml method when accessing Zope via IIS 4.0. Comments? Suggestions? Observations? __________________________________________________________________ Jim Sanford ^ Database Engineer ^ ^ ^ Accelerated Technology, Inc. ^ ^ 720 Oak Circle Drive East ^ ^ ^ Mobile, AL 36609 ^ ^ ^ Voice: 334-661-5770 fax: 334-661-5788 ^ ^ E-Mail: Jsanford(a)atinucleus.com Web: http://www.atinucleus.com Source Code, No Royalties, Any CPU...It just make sense ! __________________________________________________________________

Jim, I don't have any experience running under IIS, but Amos Lattier does. He was the first to get pcgi-wrapper.exe working with it. The Win32 hack of pcgi-wrapper was mainly a proof-of-concept thing. I tested it using Apache. Win32 incurs a substantially higher process launch cost (Unix's fork has a more efficient copy-on-write mechanism). Hopefully, Amos will join this thread. Until then, one suggestion might be to set the System Environment Variable: PYTHONUNBUFFERED=1 (or set in Zope.cgi). Good luck. Jeff Bauer Rubicon Research

Creating a list object under DTML
by Timothy Grant 06 Sep '99

06 Sep '99

Hi, I know that if I have a variable on a form I can contstrain its type using varname:type, however, I would like to create a non-form variable that is of type list and haven't been able to figure out the correct syntax to do so. Normally I use REQUEST.set('varname', value) to create non-form variables, but I can't figure out how this works in the context of a list. Any light would be greatly appreciated! -- Stand Fast, tjg.

Stopping PCGI publisher from starting
by Alexander Staubo 06 Sep '99

06 Sep '99

Sorry if this is all easily understood by studying the source code -- and I'm sure it is -- but please help me out anyway. If ZServer is running, it seems the PCGI wrapper -- or mod_pcgi? -- is able to connect directly to ZServer, without the need of pcgi-wrapper/pcgi_publisher.py. This is fine, and it is our current scenario, which works great. Unfortunately, if ZServer is _not_ up and running, the PCGI wrapper will kick in and start serving stuff itself. This is annoying when doing maintenance that involves stopping ZServer. Is fixing this as trivial as commenting out stuff from Zope.cgi? The main reason for my trouble is that occasionally I find the Zope OFS is behaving oddly -- SQL connections suddenly being closed and refusing to open, for example -- and in these cases I often find pcgi-wrapper running. This happened again just five minutes ago, and the process list looked like this: [...] 16947 ? S 0:00 /usr/local/apache/bin/httpd 16968 ? S 0:00 /usr/local/apache/bin/httpd 17111 ?
