You can use the absolute_url() method to get an absolute URL to use for the link. Iirc the #tree tag also gives you an (undocumented, last time I checked) attribute called tree-item-url which you can access like so:  <a href=""></a>  How would unlinking the folder names solve your problem?

Re: Zope digest, Vol 1 #289 - 28 msgs
by Matthew J. Probst 23 Jun '99

I guess I'm confused as to the "accepted" way to get virtual hosts running under Zope, if such a thing even exists. I have two domains that I would like to use Zope with. A company I work for would like to host many domains with Zope. As far as I see, there would be two approaches to this on the Zope side: 1. Redirecting different parts of the URI namespace to different parts of Zope's internal database 2. Redirecting different parts of the URI namespace to different Zope processes. I can see where (1) would be beneficial for different virtual domains that need to access much of the same information, and where (2) would be beneficial for modularizing sites into independent units. I've looked in the archives, and looked at postings here, and really wonder whether the question I'm thinking about is the one answered by people posting various Rewrite rules here. Of course there is the parallel issue of which web server to use to redirect the URI namespace. I have Apache, and I'm interested in ZServer in the alpha version, but I understand that that is unsupported. However, for the sake of conversation and understanding, can the ZServer in the alpha distribution accomplish the same role as Apache, in redirecting different virtual domains to seperate Zope processes or seperate trees of the Z object database? Assuming that ZServer and Apache do or would eventually support this mode of operation, would ZServer offer better resource usage through its multithreaded nature?

ZServer definatly isn't unsuported, but it is beta, which means you may run into bugs. We would love to hear about any bugs you run into. Now, in the case that ZServer doesn't impliment a feature you want, that would have to be submitted as a feature request to the Collector for consideration to be included in the next or subsequent releases. Note that although ZServer is beta, Zope 2.0 is *alpha*. > However, > for the sake of conversation and understanding, can the ZServer in the > alpha distribution accomplish the same role as Apache, in redirecting > different virtual domains to seperate Zope processes or > seperate trees of > the Z object database? > ZServer doesn't have nearly the configurability of Apache. The short answer is no, although I bet a good python programmer could hack up a quick solution to their specific problem rather well. > Assuming that ZServer and Apache do or would eventually > support this mode > of operation, would ZServer offer better resource usage through its > multithreaded nature? The jury is still out on that questions. Zope 2.0 appears to be definatly much faster than 1.x w/ ZServer, but substantive analysis has not been done with Andrew's new mod_pcgi apache module. I suspect that ZServer and Apache+mod_pcgi will similarly. What ZServer buys you is the ability to do webdav (which Apache can also do, if you patch it) and especialy FTP and XML-RPC (protocols Apache can't, and never will speak). Note however, that Apache can work *with* ZServer using pcgi, so Apache+mod_pcgi+ZServer will get you all the benefits: Apache's configurability as a webserver, mod_pcgi and ZServer's speed, webdav, FTP, and XML-RPC support. -Michel > > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Example: How I handle Virtual Hosts and mixed static/dynamic serving
by Evan Simpson 23 Jun '99

23 Jun '99

I am serving a set of websites with different domain names from a single server, using Apache (1.3.2)'s Virtual Hosts feature. For reasons too irrelevent to go into here, I serve some URLs (mostly images and other binary files) statically through Apache, and the rest from Zope. All dynamic content is served from a single Zope server, from root folders each of whose ID is the 'site name'. Most static and dynamic pages must be able to refer to each other with relative paths, so I can't always distinguish them by hostname, port, or URL prefix (the usual /Zope/ hack). All pages, including those from Zope, must be reachable with URLs which end in '.html', since the pages are being edited (and the links maintained) in Dreamweaver, which uses Windows file extension associations <choke>. On the other hand, I don't want to have to go around making Zope objects with IDs ending in ".html' I came up with the following framework: 1. I can force a static URL by prefixing it with the 'site name'. 2. No Zope object has a period in its ID, so any URL with a period is static and any without is dynamic (but see #3). The default homepage (a bare "/") is also static. 3. In Dreamweaver, all dynamic pages end in '.py.html', but they're stored in Zope with no extension. Apache strips all occurrences of '.py.html', and hands the stripped URL back to the client. 4. A dynamic URL is automatically prefixed with the 'site name', unless it already starts with '/Zope/' (for root access). For the site named "4am", I have: #1 and stop RewriteRule ^/(4am/.*) /home/httpd/html/$1 [L] #3, repeat and show to browser RewriteRule ^/(.*)\.py\.html(.*)$ $1$2 [R,N] #2 and stop RewriteRule !^/([^.]+)$ - [L] #4 RewriteRule ^/Zope/(.*) /$1 [S=1] RewriteRule ^/(.*) /4am/$1 RewriteCond %{HTTP:Authorization} ^(.*) # All on one line: RewriteRule ^/(.*) /home/httpd/cgi-bin/Zope.cgi/$1 [E=HTTP_CGI_AUTHORIZATION:%1,E=ZOPE_RAW_URI:SCRIPT_URI,T=application/x-httpd -cgi,L] Now, one problem remains; Zope uses the path constructed by object traversal to construct BASEn and URLn variables and to auto-insert BASE links. This means that my framework causes "http://4-am.com/parrot/is/dead" to have an incorrect  of "http://4am.com/4am/parrot/is/dead". Following multiple links could lead someone to something like "http://4am.com/4am/4am/4am/4am/4am/parrot/is/dead". I had to patch ZPublisher to use SCRIPT_URI (indirectly, through ZOPE_RAW_URI) as follows: In ZPublisher/Publisher.py, around line 360, find line "URL=request.script". Directly after this line, insert: rawURI=request.environ.get('ZOPE_RAW_URI') if rawURI: def cvtpart(part, envget = request.environ.get): return envget(part, part) rawURI=join(map(cvtpart, split(rawURI)), '') then change "setBase(URL)" to "setBase(rawURI or URL)" around lines 380 and 460. Finally, directly before "request['URL']=URL" (around line 570-580), insert: URL=rawURI or URL This all *seems* to work just fine, although I may have missed a corner case or two (do I need to worry about __bobo_traverse__, for example?). In case the above is too abstract, here's some examples: http://4am.com/ == static homepage http://4am.com/images/squishfoot.png == static image http://4am.com/4am/images/squishfoot.png == same static image http://4am.com/Zope/manage == Manage all of Zope http://4am.com/manage == Manage "4am" folder in Zope http://4am.com/manage.py.html == same http://4am.com/Zope/4am/manage == same

Since this release, we've updated the select trigger module. Please try the latest ZServer (from 2.0.0a3 or CVS) and let me know if you still experience this behavior. Thanks. -Amos P.S. If you want you can just update the ZServer/medusa/select_trigger.py file.

Gadfly and Zope, sharing database files
by Alexander Staubo 23 Jun '99

23 Jun '99

Has anybody any experiences with using Gadfly to share a database between several processes (or even inside a single process), such as Zope and an external script? I have a situation where I have a Python script running externally to Zope that updates a Gadfly database; then I'd like to build a Zope site around this database. Does/can Gadfly gracefully share files, or does it open its files in "exclusive" mode? I have not tested out Gadfly's client/server capability. Any luck with this? What does Zope use? Oh, and can I easily update the Gadfly distribution that comes with Zope with a new one? I know this was discussed a little while ago, but I didn't see anything conclusive coming out of that discussion. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.
