Hi Irene, you can also debug on client side with ethereal or tcpwatch or whatever. Ethereal would be the big hammer buts very powerful. (http://www.ethereal.com, make sure you download libcap for windows too. You usually capture with "port 80" as filter expression, then "follow tcp stream" on the packets). It might be the problem if your windows clients use excessive HTTP1/1 in opposition to some old client on the other solaris box. This can be a problem with threads. I think installation from sources should fix that. Regards Tino --On Montag, 6. August 2001 14:57 -0700 Irene Barg <ibarg@as.arizona.edu> wrote:
Dieter,
I can't try TCPWatch or webdebug because they both require Python threads. I don't have root privilge on this system and the Python version running is 1.5.2 without threads. I had thought that the Python library that came with Zope was self-contained?
When I downloaded the Zope Solaris binary, I placed the required Zope modules I needed in my PYTHONPATH directory, then edited the Zope "start" script to read:
nickel% pwd /home/barg/Zope-2.3.2-solaris-2.6-sparc nickel% more start # ! /bin/sh PYTHONPATH=.:/home/barg/zope/lib/python1.5/site-packages:/home/barg/pymodules export PYTHONPATH LD_LIBRARY_PATH=.:/home/barg/mysql/lib/mysql export LD_LIBRARY_PATH reldir=`dirname $0` PYTHONHOME=`cd $reldir; pwd` export PYTHONHOME exec /home/barg/Zope-2.3.2-solaris-2.6-sparc/bin/python \ $PYTHONHOME/z2.py \ -u barg "$@"
Assuming that the Python built with Zope had threads. Per your suggestion, I restarted it with STUPID_LOG_FILE and with debugging turned on. Re-issued the same Update request and noticed that I now have a 'core' file with the same time stamp as my last request, but the Zope.log doesn't give me any more info than that at startup:
nickel% tail var/Zope.log
nickel% tail var/Zope.log 2001-08-06T21:41:34 INFO(0) ZServer HTTP server started at Mon Aug 6 14:41:34 2001 Hostname: nickel.as.arizona.edu Port: 8080 ------ 2001-08-06T21:41:34 INFO(0) ZServer FTP server started at Mon Aug 6 14:41:34 2001 Hostname: nickel.as.arizona.edu Port: 8021 ------ 2001-08-06T21:41:34 INFO(0) ZServer PCGI Server started at Mon Aug 6 14:41:34 2001 Unix socket: /home/barg/Zope-2.3.2-solaris-2.6-sparc/var/pcgi.soc
BTW, I develop on a my Toshiba notebook, running Linux, Python 2.0 and Zope 2.3.2 built from source. I do not see this problem using it as the Zope server, coming from IE on the PC. I guess I'll have to install my own version of Python (with threads), and try to compile Zope on my Solaris system. This concerns me a little because the gcc compiler is not on my Sun system either. oh well :-(
I appreciate your input. Cheers, irene barg

This page cannot be displayed. The page your are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or your may need to adjust

Now, what "should" happen is, when they press the 'Submit' button, a DTML method is called (using method="POST"), this method calls some Python scripts, a ZSQL method, then sends a reply to the client's browser. Of course this never happens on a PC running IE or Nescape 4.7. I do not see this behavior if I come into my Zope site from another Sun workstation in my office (using Netscape 4.7), but I can go down the hall and get the same error on a PC running Windows 2000 and IE. Can anyone tell me what may be going on, or how I can go about debugging this? Shane's TCPWatch utility (or any other TCPLogger) may help you to see precisely what happens and what the difference between the two constellations is.
BTW, does your Zope die when you see this error (you should have enabled logging with "STUPID_LOG_FILE=logfile" and check the logfile). If so, you may have a core dump or an error indication in the log file.
