newbie dtml-in question objectValues
by Alric Aneron 12 Jan '06

12 Jan '06

Hello, I am trying to find how to get the relative path of an object. If i do: <dtml-in "objectValues('DTML Document')"> <dtml-var URLPATH0> </dtml-in> URLPATH0 does not give me the relative path of the objects interated, but rather the path of the object doing the iterating (my method). I want the path of every DTML Document the loop encounters. absolute_url works, but it puts in the undesired filename and "http://...." in front etc. Thanks in advance!

I'm probably stating the obvious here, but a ZEO server + at least one ZEO client is generally advisable at the very least for debugging purposes, in which case dual CPUs/cores can be somewhat helpful (though the zeo server is not terribly processor intesive in my experience). Even with a non-ZEO setup, dual cores could obviously be helpful if you were running other cpu intensive processes like an RDBMS on the same system. Alec

Zope, Apache, REMOTE_USER
by Robert Boyd 11 Jan '06

11 Jan '06

I'm using Apache 2.0, and I cannot find a solution to passing the value of REMOTE_USER from Apache to Zope when using a rewrite rule. I have Apache rewriting requests for Zope, and hooked into Tomcat with mod_jk. My users login through a servlet, and Apache has REMOTE_USER available to it. But any subsequent request to Zope loses this value. I used to have this all working when using FastCGI, but I'm hoping to use only mod_rewrite. Is it possible? Thanks, Rob

I believe that is an overly broad statement, not necessarily true in all cases. It really depends on the operating system's thread library that Python implements it's thread module on top of (as documented at http://docs.python.org/lib/module-thread.html) and how that system threading package schedules threads on the available CPUs. The real answer is "maybe; it depends". Jeff D

Problem with Zwiki mail-out
by Tracy R Reed 10 Jan '06

10 Jan '06

I am using Plone 2.1 and Zope 2.8.4-final, python 2.3.5, Zwiki 0.46.0 I am not having any luck getting mail-out working. The subscribe button won't appear on my zwiki and I am out of ideas as to why. I've uninstalled and reinstalled zwiki, deleted and remade the mail_replyto property, deleted and remade the MailHost object...people can get their passwords emailed to them when they sign up so I know MailHost is configured properly. I have read HowToSetUpMailOut on zwiki.org and it seems so simple. I successfully set this up once on a clients Zwiki but no longer have access to that system to look for differences. Am I missing something here? Thanks in advance for any help that can be provided.

Zope freeze issue
by gael＠pilotsystems.net 10 Jan '06

10 Jan '06

Hello Zope users ! We are deploying a Zope on a customer's server, but we have regular freeze (Zope stop to answer any requests). The Zope is running Plone 2.1 with some custom products. Here are all the informations I gathered on the issue: - Zope version 2.8.4 - Plone version 2.1.1 - Python version 2.3.5 - OS: Debian GNU/Linux, sarge, 2.6.8-smp kernel - Computer: dual Xeon with 4Gb of memory - Zope is behind Apache configured as reversed proxy Symptoms: - The Zope stops to answer incoming http request on regular intervals - When this happens, the CPU isn't used mch (about 2% used), and the memory isn't full (1Gb used on the 4Gb total) - Inspecting the Python process with gdb shows a normal operation: a running thread, and others waiting in, and then after a while (dettaching gdb, waiting a bit, and reattaching gdb) another thread running. The other threads are in: #0 0x40026d0b in sem_wait(a)GLIBC_2.0 () from /lib/tls/libpthread.so.0 #1 0x00000004 in ?? () #2 0x080d29de in PyThread_acquire_lock (lock=0x87b1e70, waitflag=1) at thread_pthread.h:406 - Looking at netstat shows a few established connections to the Zope process, but not much (2-3 on avergae) What we tried: - We tried using ZEO, didn't change anything - We tried with the default 4 threads, with 10 threads, and with up to 40 threads, nothing changed I'm currently out of ideas to investigate this issue. Does any of you have an idea of why could this happen ? Or an idea of what I could try to undersatnd what's happening ? Any idea is dearly welcomed.

[ANN] TextIndexNG 3.1.4 released
by Andreas Jung 10 Jan '06

10 Jan '06

I am pleased to announce the release of TextIndexNG V 3.1.4. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Changes in V 3.1.4: - fixed RTF converter - fixed HTML converter - improved ATFile adapter Requirements: - Zope 2.8+, Zope 3.1+ Download: http://sf.net/projects/textindexng Project page: http://opensource.zopyx.biz/OpenSource/TextIndexNG3 For installation and documentation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. Windows binaries of the required extension modules are currently not available (any volunteers?). TextIndexNG V 3 is published under the ZPL.

installing zope in a "web" hosted environment
by Daniel Gross 09 Jan '06

09 Jan '06

Hello, I am using a linux web hosting service, who has recently installed python into apache. Usually i install web products via ftp. After reading how to install zope (and plone), I couldnt find a reference how to install zope using ftp only. Is there a way to do so, also, so that zope does not use its built in web server but the apache server of the web host. appreciating your response, Daniel

Man, > I'm sorry for the inconvenience. Not a problem: if one person doesn't understand what they're seeing, then at least a hundred more won't understand it either, and it's very good to have a discussion about it archived on a public mailing list then. FWIW, I don't know why Zope doesn't display anything useful in the console anymore, and I don't even know whether that's unique to Windows. >> Or another way (something I'd never do in real life, but I guess some >> people do) > I always run Zope in the console. So do I, but there's difference: I open a DOS box and type "bin\runzope" myself. What I never do is use the Start menu "shortcut". A DOS box you open yourself stays visible even if Zope dies ungracefully, and after the first time you type "bin\runzope" you only have to hit two keys (up-arrow ENTER) to start it again. > The only reason I even use the Windows version is for development.

When I develop, I restart Zope > all the freeking time, so the faster the restart, the better. Doesn't the ZMI have a "restart Zope" button? If you open your own DOS box, then a sloppy all-keyboard restart dance is "Ctrl+Break up-arrow ENTER", and a careful all-keyboard restart dance is "Ctrl+C up-arrow ENTER". The latter gives Zope a chance to close files gracefully, but by the same token it takes longer for Zope to shut down. "Ctrl+Break" kills the process instantly (and runs some risk of leaving data in I/O buffers without writing it to disk).
