This is a poor answer (as most here know I don't have the mental horsepower to provide good responses :^), but...our _intention_ over time is to have "ZServer" allow objects to be published via PCGI, FastCGI, HTTP, FTP, and CORBA simultaneously. Ideally we'd get some kind of Python implementation into the Medusa handler layer. Obviously this approach has some serious drawbacks... Anyway, I realize that I'm not providing much of an answer, so sorry :^( --Paul

Hm. Is your Zap .pcgi file named Garros or does your RewriteRule look for Garros and then call PCGI? If so that is why you need to use Garros to reach the server. ZServer can server right out of Zope and doesn't have this problem. Your description makes this sould like it is a production site, I would not suggest running ZServer on a production machine as it is alpha and still buggy. > > Switching back to ZAP I got the following error: > > <FONT SIZE="+2">Temporarily Unavailable</FONT> > <P> > The resource you requested is temporarily unavailable - > please try again > later. > </TD> > </TR> > </TABLE> > (102) failure during connect >  > </BODY></HTML> > > Seems like ZServer changed my root id from "Gaaros" to nothing. This error comes from PCGI. It can't find your .cgi file so Zope isn't even being launched.

The Database itself is not a Pickle, it is a database of Pickles. I have attached a small 5K script that will be released with 1.10.3 which paruses the database and generates reports. In the future we are intending it to translate the entire database into XML for transport.

We had to spend a lot of time figuring out Gadfly in order to host it inside Zope. Thus we labeled it "Demo". I imagine that it is best for everybody if we take Gadfly out of the base Zope and make it an external, no-warranty package like the MySQL support. --Paul

I've been awfully interested in XML in the last few days. Can you describe what user-visible benefits PHP delivers due to its integrated XML parser? Additionally, we are working on Zope searching for a consulting project right now. Actually it is Zope Cataloging. It's still a consulting-only option, but plans are that eventually it will go "below the line". > I found out about Zope Monday morning, dl'ed it, installed it, got > one or two things working... and have been worried sick ever since.

This is the main reason I replied. Having Zope as a free and Open Source(tm) platform is the heart of our business plan. A closed Zope would basically mean we start over completely as a different company. Thus, closing Zope is roughly equivalent to closing our company. With _that_ said, we still need to provide some assurances that we won't legislate the connection between Zope and DC. First, we are trying to keep some arm's length distance between zope.org and Digital Creations. We hope to formalize the way the community participates in the platform. We expect to make it lucrative for other businesses to participate. At the same time, we intend to pursue commercial opportunities atop the platform for vertical applications. Ultimately this is the same question put to Netscape regarding Mozilla during the AOL talks. The answer is simple: "The genie is out of the bottle." Since it is open sourced, Digital Creations must *earn* its stewardship of Zope. If we don't we'll become less relevant. Earning the community's enthusiasm is pretty simple, I think. Unfortunately we aren't doing a good job right now, though we are trying damn hard. But we'll keep trying... In the meantime, I'm absolutely ecstatic to see folks in the community step forward over the last month and lead the way. > e) Can I 'point' an Apache virtual server to run a Zope cgi (ie > dropping the :port requirment).

We put them in the database. The 3 Mb Zope binaries are served out of the database, the PDF files are served out of the database. This works so well I don't even think about it any more. --Paul

Plenty of problems. Please Help
by Pavlos Christoforou 05 Mar '99

Zopistas I have encountered problems mainly associated with ZServer and ZAP: I am using Zope-1.9.0 and the preconfigured Apache server to run my Zope site. Last night (a couple of hours ago!) I installed ZServer. It wouldn't run and I had to add the following to start.py to fix it: import sys,os sys.path.insert(0,os.path.join('..','lib','python')) Later on upon entering the management screens I noticed that the id of the top level folder dissappeared which caused the paths to my objects to change. With ZAP (the preconfigured apache) I would visit: http://www.gaaros.com:8080/Gaaros/ to get to the top level directory but with ZServer is: http://www.gaaros.com:8080/ which spoils all kind of links that people have on my site. Switching back to ZAP I got the following error: <FONT SIZE="+2">Temporarily Unavailable</FONT> <P> The resource you requested is temporarily unavailable - please try again later. </TD> </TR> </TABLE> (102) failure during connect  </BODY></HTML> Seems like ZServer changed my root id from "Gaaros" to nothing. I called PickleDictionary on Data.bbb directly from python but I could not even see the subobjects. BTW can the Zope Data.bbb be accessed directly from PickleDictionary?? Also trying to shut ZServer from the control-panel results in a core dump. Ok enough for now, its very late and I cannot think anymore. If anybody has any clues about the root object id problem please let me know. Thanks Pavlos

need help with IIS/ODBC
by Jay Ashton 05 Mar '99

05 Mar '99

As a novice (who's loving Zope!) I'm having a terrible time trying to get Zope1.10.2 on NT with IIS to connect to MS SQL with a Z ODBC connection. Previously I had no problem getting Zope 1.9/ZopeHTTPServer to connect to MS SQL via Z ODBC. Recently I upgraded to 1.10.2 without a hitch, and was able to run it with IIS 4.0 after putting the (PCGI executable?) MYZOPE.exe in /InetPub/scripts/ and turning off in IIS both Basic Authentication and NT Challenge/Response as I read here in the list. My problem now is that when I try to open my db connection (exactly the same connection that was working with 1.9 & ZopeHTTPServer) I get the following error from IIS: >HTTP Error 400 >400 Bad Request >Due to malformed syntax, the request could not be understood by >the server. The client should not repeat the request without modifications. In trying to figure out what's going on I've noticed a couple things. First, and I think most illustrative, if I try to add a new Z ODBC connection, none of my ODBC sources are showing up in the available list (except the default 'LocalServer, SQL Server') - whereas if I run my 1.9 Zope with ZopeHTTPServer all my ODBC connections show up just fine. Also, running my new 1.10.2 Zope/IIS with the faulty db connection side by side with the functioning 1.9/ZopeHTTPServer, I printed our the environment variables of both and noticed some differences - USERPROFILE's are Default User vs. Administrator, and the 1.9/ZopeHTTPServer contains variables not contained in the 1.10.2/IIS environ: HOMEPATH, TEMP, USERNAME, HOMEDRIVE, USERDOMAIN, PROMPT, LOGONSERVER, TMP. I attempted to set at least USERDOMAIN in the 1.10.2/IIS environ, with no luck. I've read all the posts from the list that I could find dealing with IIS and ODBC, but couldn't find anything with info on this type of trouble. Have I made a boneheaded mistake and started to look in the wrong places for the fix? Any help/info/pointers would be hugely appreciated as I continue to bang my head on my keyboard hoping that I'll soon clear this hurdle and get back to having fun with Zope! Thanks! Jay

Where exactly is the file? find out by doing a locate 'libmysqlclient'. Let's assume that it is in /usr/local/mysql/lib. The easiest way to accomplish what you want is this. 1. cd /etc 2. vi ld.so.conf 3. Goto the end of the file and add a line that says '/usr/local/mysql/lib' replace this with the exact location of you libmysqlient.so.6 4. save the file 5. run 'ldconfig' 6. run 'sync' twice, this just makes sure all changes are written to the disk. This adds the mysql lib directory to the lib search path.
