This nice how-to explains the way it can be done: http://www.zope.org/Members/beacon/install_instructions This how-to doesn't say it, but you also have to uncomment the modules that you need from the Modules/Setup file in the python source code installation (like zlib for example). Note: if your old python is installed under /usr/local, then you can specify another path in the configure script (read the comments inside this file). Regards, Josef

Can't get tracebacks to show
by Paavo Parkkinen 10 Apr '03

10 Apr '03

I have Zope 2.6.0 installed and can't get tracebacks to show anywhere. I've been searching the net for clues, but nothing seems to help. I've tried the Z_DEBUG_MODE, BOBO_DEBUG_MODE, -D. Here is my 'start'-script, if someone could point out what I'm doing wrong. ----- start ----- #!/bin/sh umask 077 reldir=`dirname $0` cwd=`cd $reldir; pwd` # Zope's event logger is controlled by the "EVENT_LOG_FILE" environment # variable. If you don't have a "EVENT_LOG_FILE" environment variable # (or its older alias "STUPID_LOG_FILE") set, Zope will log to the standard # output. For more information on EVENT_LOG_FILE, see doc/ENVIRONMENT.txt. BOBO_DEBUG_MODE=yes Z_DEBUG_MODE=yes EVENT_LOG_FILE="var/event.log" ZLOGFILE=$EVENT_LOG_FILE if [ -z "$ZLOGFILE" ]; then ZLOGFILE=$STUPID_LOG_FILE fi if [ -z "$ZLOGFILE" ]; then EVENT_LOG_FILE="" export EVENT_LOG_FILE fi exec /usr/bin/python2.1 $cwd/z2.py -D "$@" -w 8080 -f 8021 -u zope & ----------------- -- paavo. wu wei er wu bu wei

I think it's a responsibility of each administrator to do a backup before doing a software upgrade. Anyway, now I just remmember that somebody disscussed just some days ago a way of correcting mistakes if you have already upgrade your zope. He said that you had to export as XML, look for a string (If I'm not bad it was something like <object>, you've to look the archives) erased it and reimport the object again. Regards, Josef.

Zope temporary files bloating /tmp/
by Heimo Laukkanen 10 Apr '03

10 Apr '03

Hi all, a sysadmin-friend of mine noticed that on their system Zope 2.6 is creating a large number of tempfiles that bloat the tmp partition on the system and do not get deleted/released for a long time. In the worst case there are over 200 megabytes of these tempfiles bloating the temp and nothing else than a restart seems to help. I would need some help for debugging this kind of behaviour and what could be done. So far I know that tempfiles are used for example in situations of upload or downloads, where Zope writes the file to a tempfile before/after it is written to ZODB. Any help and insight would be appreciated. -huima

Then see if it inherits from ObjectManager. If so, see the second point of my how-to. > I've succeeded at accessing it with a 2.5.1 installation, > and I've made a backup, now I'll try to reimport into > 2.6.1 tomorrow if possible. Actually, that was the solution proposed several months ago. (see my how-to) Regards, Josef.

Unfortunately we cannot switch to debian at the moment. We think the problem might be related to the "--with-thread" Option when compiling python. Zope 2.6.1 seems to need "libpthread.so". At the moment we have the impression python 2.1.3 on redhat 7.3 does not compile the way we wanted to do (./configure --prefix=/usr/local --with-lcrypt --with-thread=/usr/lib/). We are still trying .... ;-) Seila -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln! Fotogalerie online mit GMX ohne eigene Homepage!

can't start new thread
by seila＠gmx.de 10 Apr '03

Hi all, we have just installed zope to a new server (RedHat 7.3, Zope 2.6.1, Python 2.1.3, Apache 1.3.27, multiprocessor: Dual Xeon HotSwap, ICP Vortex Hardware Raid 10). Since we have a problem reaching zope behind apache, we started prozess in debug modus. Zope seems to start normally (port 8081, 8021), after the first call of the domain in the webbrowser (we get 500 server error), we find these 2 lines in the debug log: ERROR(200) ZServer Server Error: thread.error, can't start new thread file: /zope/Zope-2.6.1/ZServer/PubCore/ZRendezvous.py line: 32 Has anybody an idea what the problem could be? Maybe the problem mentioned in: http://www.zope.org/Members/glpb/solaris/report_ps (Python Global Interpreter Lock)? Any ideas? Thanx a lot, Seila -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln! Fotogalerie online mit GMX ohne eigene Homepage!

I did the same with the ZCatalog product directory and now it works fine. Could there be any problems caused by that? perhaps you have a bug fix ready or a hint for me ;)

Add ZCTextIndex Error on Zope 2.6.1 stable release
by Chris 09 Apr '03

09 Apr '03

Dear people at Zope.org, at the moment I work a bit with Zope to get more into it and I have a problem that seems to be fixed on the beta1 release: I get an error message when trying to add a ZCTextIndex - the error message says "Error Type: LookupError Error Value: Lexicon "(name of the lexicon here)" not found". What can I do besides installing the whole beta release or is there a bugfix available? I tried to copy the folder of ZCTextIndex from the beta release Folder to the Zope 2.61 one but this did not work (it was worth a try ;) ) Please help! Thanks in advance, and keep up the good work!
