IsDaZope: a Zope checker and relauncher
by Jerome ALET 26 Apr '00

26 Apr '00

Hi there, Because I was hurt by the Zope hanging problem, and because I wanted to contribute something back to the Zope community, I've written a python script which can periodically check if your Zope server is still serving requests correctly, and restart it if it's not the case. It's called IsDaZope and you can get it as a tar+gzip file, as well as a document which explains how to use it, at: http://www.zope.org/Members/jerome Unfortunately, Murphy's law has hurt me too: my Zope served has not hanged today so I was unable to test my program in this situation. I hope it will hang tomorrow ;-) I've tested it when manually shutting down Zope, and it works fine: it can detect this situation and restart Zope. You can also use isdazope to detect if a particular HTTP server seems to be a Zope server or not. In order for isdazope to work correctly you should: - read the documentation and use the correct arguments for your situation on the command line - launch it AFTER having launched Zope. I suggest you launch it in the background. isdazope is distributed under the Gnu General Public License. Please feel free to send me any feedback, especially if you find this software useful or too buggy. Enjoy. Jerome Alet

newbie zope ? <dtml-var standard_header>
by Jonathan Park 26 Apr '00

26 Apr '00

How can you add "<dtml-var standard_header>" by default(like newly created dtml method or doc in zope) to a newly created document made my a form. When they create a document using the form I want <dtml-var standard_header> to be included in the top of the body. I tried <textarea><dtml-var standard_header></textarea> thinking it would work, but what resulted was not what i intened,instead i got the values in the variable, which makes perfect sense, now that I think of it. thanks ahead! -jon

Folders, one more time!!
by Pierre Rougier 26 Apr '00

26 Apr '00

Hi, There is a lot of questions about Folders on the list in our days..... I got one too... ;^) I would like to make a SpecialFolder, with its own methods and objects. I tried doing it by using products and ZFactories, but I do not manage to insert my special Folders as a normal Folder in the hierarchy Zope.. Is there a simple way to do it, I mean having my SpecialFolder in the Add list, and when adding it, inserting it in the zope hierarchy as a Folder which can be managed, with object by default. (I hope I have been clear.... but not sure)! A great thanks to any people who would be able to help me....... Pierre PS: can I find somewhere the list of DTML functions (as manage_addProduct and such functions...)

All dates in Zope are broken in daylight saving time zones
by Gregor Hoffleit 26 Apr '00

26 Apr '00

Just a quick note and RFC: If I'm not completely wrong, all DateTimee objects are broken when created during daylight saving time. If your Zope machine is working in a daylight saving time timezone currently, try to create a new object (e.g. a DTML Document) and compare the "last modified" date (most important the timezone therein) with the real date on that machine (e.g. the output of "date -R"). In my case (timezone Europe/Berlin, i.e. currently CEST=Central European Summer Time=GMT+2), I get this: Last modified: 2000/04/25 13:46:50.7635 GMT+1 date -R: Wed, 26 Apr 2000 13:47:32 +0200 This is on a Debian system, but I guess this happens on all systems that provide handling of daylight saving times (don't know about Windows, though). A more detailed report about this problem can be found as Collector #1204 http://classic.zope.org:8080/Collector/1204/view Later on I found that the same thing has been reported already a month ago as #1135 (http://classic.zope.org:8080/Collector/1135/view) If nobody else cares, I'll work on a fix for DateTime.py.

Unfair Linux Threads And Python Oh My
by Tony Rossignol 26 Apr '00

26 Apr '00

I have added my observation to the ZWiki devoted to Zope in production environments. http://www.zope.org/Members/tseaver/Projects/HighlyAvailableZope/UnfairLinu… I don't know if this addresses all our troubles but it might be worth investigating. I was able to verify, with the example python code, that this thread thing is an issue on two of our three server; the two that exhibit unexplained restarts. The third server which does not restart also does not suffer from this thread problem. Does anyone know how to change the scheduling policy for zope/python? In the quote from the LinuxThreads FAQ there appears to be an indication that SCHED_FIFO or SCHED_RR would more precisely define the scheduling behavior. Anyone know how to do that? Would it help? There is also some indication that this issue is addressed in pthreads 0.8. I've upgraded a workstation with glibc 2.1.3, which I believe should have ptheads 0.8, and the problem still exists. Any ideas? -- ------------------------------- tonyr(a)ep.newtimes.com Director of Web Technology New Times, Inc. -------------------------------

I had the same problem. I didn't try <dtml-with> but putting REQUEST in the "Arguments" field seems to work.
