December 1999 - Zope

FYI: Linux Magazine and Zope
by Paul Everitt 28 Dec '99

28 Dec '99

The January 2000 issue of Linux Magazine contains an article "Gold Rush: Venture Capitalists Discover Linux". Alongside six profiles, Digital Creations and Hadar Pedhazur took up about half the print space! This is a really, really good article that captures almost the "definitive version" of early Zope pre-history, including the real story behind the Bobo name. It even contains a picture of Hadar, and I hear the pull-out, pin-up version of his photo is available by mail order. :^) Make sure you read the author bio at the end of the piece. That, combined with the other people in the story, make this a pretty hot thing to come out! --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909 ----------------------------------------- The Open Source Zope application server http://www.zope.org/

First point: if the page is being accessed through plain HTTP, the SSL_* environment variables may not be created at all. Second point: in current versions of mod_ssl, you have to turn on the creation of the SSL_* environment variables; they're disabled by default because some time is required to create them. Adding "SSLOptions +StdEnvVars" to your httpd.conf is required to enable them; for best performance you might want to limit the option setting to just CGI scripts, including Zope. -- A.M.

Dumb object aliasing question
by Darrell 28 Dec '99

28 Dec '99

If I add a new image, call it img1 and view it outside of manage, all is well. If I replace that image and view it. It hasn't changed ?? If I view it in manage it's the new image. Restarting Zope doesn't help. If I now change this image in manage a second time it won't change. But it's size changed, just not the image. I picked up the CVS version deleted Data.fs and started over, with the same results. Shouldn't I be able to change an image ? Any idea where the code is that decides to render one way for local manage and another way for the remote user ? I'll find it eventually ....gurrr --Darrell

Find all *empty* values using ZCatalog?
by Itamar Shtull-Trauring 28 Dec '99

28 Dec '99

I would like to search using ZCatalog for all objects that have an empty attribute, e.g. <dtml-in "catalog({'history': ''})"> only this returns all objects in catalog. Any ideas? I do not want to do <dtml-in catalog> <dtml-unless history> ... </dtml-unless> </dtml-in> -- Itamar S.T. itamars(a)ibm.net

I'll find it eventually ....gurrr I ran into this same problem when I started working with Zope. I believe that the problem that you are running into is the cache in your browser (especially if you are using Netscape). Restarting Zope wont help (as you found out) and restarting your browser in many cases wont help either. You will need to go in and physically clear out the browser cache. In Netscape 4.7 it is located at Edit->preferences->advanced->cache ... hope this helps.

I can't believe you are still using that tired old Magnetron Sputtering technique -- if you would fix the thing it wouldn't sputter. :^) <snip> > Doing a Web-based user interface for this sort of thing is hard, and I agree -- one idea would be to do something like Netscape did (does?) with their Certificate Server. Configuration of this thing is hard even if you're familiar with cryptography (which I know you are :^) and probably impossible (without luck) if you aren't. They use a vertically-oriented frames interface where the left frame gives you a list of the steps in the process. The current step is highlighted. The right frame is where you actually perform the current step. It looks like these devices are built like sandwiches (how's that for a high-tech metaphor). Knowing what the sandwich looks like at all times (i.e., by viewing it in a separate frame) might be handy. (??) --Rob

SSL-vars
by Ragnar Beer 28 Dec '99

Hi, does anyone know how to find out the SSL keylength etc. with DTML (Apache 1.3.9 with mod_ssl under Linux, Zope 2.1.1 via pcgi)? I would e.g. like to display a warning when weak encryption is used by a client's browser. - Ragnar

Hi, Add a property to your document or folder. Insert the days of the week (in Swedish) inside. Test the day number. Render the Swedish name in function of the value returned. The property is a list. Each element of the list has a number :) FR >>> Magnus Heino <magnus(a)vuab.net> 28/12/99 09:08:07 >>> > ZopeTime() returns the current time as a DateTime object. The Day() method > returns the name of the day of the week. The DateTime methods are in > Appendix A of the DTML Guide. I want the name of the day of the week is Swedish. Will Zope support this (and other locale strings too i guess) in the future? Or is it possible today, have I missed something? /Magnus _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
