Re: [Zope] Cut/copy/paste problems
Hi! i knew that! :) btw, there's currently sparse document on mod_pcgi2. i'd like to change that, but i need info from you (the author ..straight from the horses mouth - so to speak) or snippets from your httpd.conf. do i need to have Zope.cgi available? i think i do since otherwise, there'll be no connection. or am i missing something? You missed pcgi-wrapper :) If you look into Zope.cgi (it is just plain text file) you'd found it is a script interpreted by pcgi-wrapper. That very pcgi-wrapper is a binary file compiled from pcgi-wrapper.c during the Zope installation process. The pcgi-wrapper binary is the program that implements PCGI protocol. When I wrote mod_pcgi2, I borrowed a lot of code from pcgi-wrapper.c. That way you do not need Zope.cgi or pcgi-wrapper - the PCGI code is already in mod_pcgi2. how can i finetune the performance? it seems that under heavy load, eg 100 simultaneous apache connection, it'd get loger to contact the server. in the browser, we'd see contacting the server, waiting for reply .. for about 3-4 secs before we get any activity/reply from server. You'd need to finetune Zope, not the mod_pcgi2 module. When you connect to Zope-behind-Apache the process is going the following path: 1) browser sends a rquest to Apache 2) Apache invokes the mod_pcgi2 handler 3) the handler passes the request to Zope 4) !!! here is the problem to finetune !!! If Zope's own pull requests handlers is empty - Zope does not handle the request, but queues the request and waits 5) after Zope processes the request it passes the results back 6) mod_pcgi2 passes the results to Apache 7) Apache passess it back to browser. Ususally there are 4 threads in Zope, and 7 ZODB connections. The first number - 4 threads - could be configured by passing parameter to z2.py. If you raise the number much, you'd need to raise he seconf number somwhere in the ZODB source code. These are points for finetuning. Actually you may need to tune more things, but these things are just totally unrelated to mod_pcgi2. Tune ZODB cache, install and learn to use cacheing Products (the are a number of caches for Zope), use squid, etc. when i do a packet dump, it seems that the machine needs a couple of SYN before getting and ACK from the server. do you think it has anything to do with mod_pcgi2? sorry if it's not. I'm pretty sure it has nothing with mod_pcgi2. SYN/ACK are properties of TCP/IP protocols, and PCGI protocol is much higher level. Oleg.

Cut/copy/paste problems in Zope behind Apache
To help me to resolve the problem I want to ask the helpful community
provide me some information. Of those who run Zope behind Apache please
tell me:
1) which way do you connect? (mod_proxy, Zope.cgi, mod_pcgi2, mod_fcgi)
2) any problem?
We run Zope behind Apache using "ProxyPass".
We have no problems.
I've been having problems with copy/paste/rename with my site, which is apache
proxypassing (mod_rewrite [p] actually) onto a siterooted subdir of zserver. I
haven't had time to set up a clean environment to evaluate exactly what goes
on when it fails but intend to over the next fortnight. I appear to have 2
separate issues:
1 Trying to copy objects from outside the siteroot'd hierarchy into it. The
object will appear in the wrong place [folder above] zope will deny it
exists if I try to access it until I restart zope. Temporary solution is to
restart zope with SUPPRESS_SITEROOT make the changes. This breaks my
production site and so isn't ideal. My long term hack will probably to
maintain a mirrored readonly site which I switch to whilst I update the main
site so access isn't disrupted. There's so much path jiggerypokery going on
with SiteAccess/SiteRoot I don't expect a clean solution!
2. Can't do anything with my ZClasses. I've tried applying the reindex patch I
found somewhere. I think my problems might be to do with the fact that I have
catalogaware zclasses that inherit from catalogaware base classes and
something isn't quite working there.
All my problems are consistent (always happen!) I'm running latest of
everything: Zope 2.2.4 apache 1.3.14,
Regards,
Ivan

I did some quick experiments. I connected directly to Zope (port 8080). Cut/copy/paste worked flawlessly. Hence the problem is not in the browser nor in the proxy nor in Zope. Perhaps the problem is in mod_pcgi2 or in the Apache or in my specific version of Russian Apache. I switched to Zope.cgi. Copy/paste worked, but cut stopped working. Oops! First sign of problem. May be this is a problem with PCGI? With mod_pcgi2 copy/paste almost always do not work. To help me to resolve the problem I want to ask the helpful community provide me some information. Of those who run Zope behind Apache please tell me: 1) which way do you connect? (mod_proxy, Zope.cgi, mod_pcgi2, mod_fcgi) i've tried proxypass, fcgi, and modpci2. and i stuck with mod_pcgi2, since this is the option with the least amount of problems/failure. 2) any problem? w fcgi, i have connection failed errors. with proxy pass, zope intermittently hangs, causing apache to reach the max client parameter set. i connect to zserver for all my management/development, so i may not see cut/copy/paste problem. but i did give it a try with mod_pcgi2 and apache1.3.9, and i can cut/copy/paste. hth Thank you in advance.
