I've finally gotten around to fixing the most serious outstanding problems with mod_pcgi; it is now actually usable. PATH_INFO is now set correctly, so Zope creates URL references that are reasonable, and the Authorization HTTP header is passed along so that you can actually log in. In my limited testing, everything I tried in Zope seemed to work fine using mod_pcgi. In short, you could actually start using it for real now. The code is in the usual place, ftp://starship.python.net/pub/crew/amk/new/ Please download it and try it out; I'm going to work on some Web pages and documentation for it. -- A.M.

Tried it on Solaris 2.5.1, Apache 1.3.6. Zope satrted and worked. I went to /manage/ screen and run through some screens, browsing what's going on. All looked good. Then I tried to edit a DTML document and pressed "Change". Zope failed, Apache sent and browser displayed "Internal server error" and Zope disappeared from memory, leaving zombie process. Trying to go to Zope - "Resource temp unavail". I have to restart apache (to reap zombie) to run Zope. The error is reproduceable - every time I tried to edit DTML Zope died to zombie. With Zope.cgi all goes well - I can edit DTML documents and view results...

Eek, you're right; the Apache child dumps core. Luckily, the fix is simple. Edit mod_pcgi.c, and around line 419, change this line: int rsize, len_read, rpos; to int rsize, len_read, rpos = 0; Stupid forgotten initialization... -- A.M.

Hello! The idea of "mount poin" (PCGI_Mount /pcgi/ directive) made me suspicious. Does it mean I can use mod_pcgi only limited way? Few quetsions, and I am afraid the answer will be "No, you cannot". 1. Could I redirect different locations to different Zope folders? With Zope.cgi and mod_rewrite I can do it: RewriteRule ^/z1/(.*) /usr/local/apache/cgi-bin/Zope.cgi/z1/$1 RewriteRule ^/z2/(.*) /usr/local/apache/cgi-bin/Zope.cgi/manage/z2/$1 2. What about virtual hosts? Zope.cgi allows it: <VirtualHost 192.168.0.1> ServerName www.server1 RewriteRule ^/Zope/(.*) /usr/local/apache/cgi-bin/Zope.cgi/virtual1/$1 </VirtualHost> <VirtualHost 192.168.0.1> ServerName www.server2 RewriteRule ^/Zope/(.*) /usr/local/apache/cgi-bin/Zope.cgi/virtual2/$1 </VirtualHost> 3. How can I run different Zopes on the same machine? With Zope.cgi: RewriteRule ^/z1/(.*) /usr/local/apache/cgi-bin/Zope1.cgi/$1 RewriteRule ^/z2/(.*) /usr/local/apache/cgi-bin/Zope2.cgi/$1 Oleg. ---- Oleg Broytmann Netskate/Inter.Net.Ru phd@emerald.netskate.ru Programmers don't die, they just GOSUB without RETURN.

The mount point idea comes from mod_jserv, where you have servlet zones mounted at different URIs in the tree.
1. Could I redirect different locations to different Zope folders? With Zope.cgi and mod_rewrite I can do it:
Currently the list of mount points contains only a single string, the URI prefix of the mount point. It would not be difficult to expand the list to contain structs instead, each struct containing mount-specific information. But I'd like to hold off on that and see if people really run multiple Zope processes on the same server. A more critical issue is to figure out why the Zope2 folder management doesn't work under mod_pcgi; you can't check off an object and hit the 'delete' button, because Zope has output a FORM element with an action of '/pcgi'. I'm not sure what's going on to cause this... probably a missed environment variable. -- A.M. Kuchling http://starship.python.net/crew/amk/ I wish I were an angry shoe, a bodiless balloon.

Of course they will. Especially Zope hosting providers want to do this.

Ok, I am not running multiple Zopes, but I definetly run virtual servers. Could PCGI_Mount be used in <VirtualServer></VirtualServer>? To which object in Zope it could be mounted?

I think it could be used, but it would still apply globally because I haven't written the merge_config function that's used to combine the global settings with virtual host-specific ones. -- A.M.

I do; I run a separate server for developing product modules and trying out ideas. Ideally I'd do it on a separate machine, but... At SwRI we also used to run two different versions of Principia frequently for similar reasons. At any rate, I'd be surprised if I were the only one.

We're running about 20, does that count? This would be very beneficial to ISPs. --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------

This helped a bit, but not much. I can start Zope from mod_pcgi and use it. But after I shutted Zope down, I cannot start it using Zope.cgi - "resource temp unavail". I have to restart Apache to use Zope.cgi :( If you don't mind, I'm sending you some minor patches (attached) for cleaner compilation. -Wall still gives some warnings, but they are not significant, I think...
