ZServer 1.11 FTP problems
by Alexander Staubo 09 May '99

09 May '99

When upgrading to 1.11, I copied the Data.bbb.* files into the new installation. Could this explain why the FTP server doesn't work properly? Even when logging in as the "superuser", the only directory I can change to is /QuickStart. All the other directories in my Zope installation give a "550 No such direcrtory" error. I get the error even when I do "cd /". Furthermore, if I do a "dir" on root level I get "Could not list directory". The log doesn't show any errors, though.

Dan-- There's a slot in the new database format for Z ODB 3 that will permit this, though it might be several months before we implement anything.

RE: [Zope] More than one Zope site for one Zope installation ?
by Alexander Staubo 09 May '99

What if Zope used the Host: header field to target a specific subtree? For example: / foo.org index_html ... bar.org index_html ... Assuming a request like this: GET /index_html HTTP/1.1 Host: www.foo.org then Zope could look at a table of virtual server name mappings (such as www.foo.org -> foo.org -- could be implemented through properties), find the correct subtree, and assume this to be the server root. So www.foo.org/index_html would in this case map directly to /foo.org/index_html. As far as I can see, Zope currently ignores the HTTP 1.1 Host: header.

Quota support
by Dan Feldman 09 May '99

09 May '99

I am interested in setting up Zope as a system in which users can create their own folders and homepages. However, since I don't have much space to do it in, I'd like to give each user a fixed quota of disk space. Is there any easy way to do this? what about using an External Method? Thanx,

Re: [Zope] Zope 1.11 timeouts with IE 5.0

Hi Alexander, Yes, others and I experienced this too. However, when I installed Medusa (delivered with Zope 1.11) everything works just fine.

Why doesn't this work?
by Craig Allen 09 May '99

09 May '99

The method below displays a list of documents in the current folder, and is invoked from one of those documents. I want it to show the title of the current document as bold and not as a link, but it always displays as a link. I can display the values of 'thisdoc' and 'id' on each line, and I see what looks like a match, but the else branch is always used. I don't understand. Any hints? Thanks in advance. - Craig    <A HREF="index_html"> In this folder...</A>     <a href=""></a>

More than one Zope site for one Zope installation ?
by lstep＠mail.dotcom.fr 09 May '99

09 May '99

I have several users who want all to have access to Zope. These users have each a domain foo.org, bar.org, but it points to the same machine, with, currently, one standard Zope installation (with PCGI with Apache). They currently use standard Virtual servers functionnality from Apache. Now I'd like to allow them to have a zope access to each of them. As they want http://user.org/ to be their base url, I need to keep the virtual servers. I think my solutions are: Make several copies of the Zope tree, and with each one, make a database, and point the the good zope pcgi in each virutal server. It is not an acceptable solution for me, as having several Zope instances gets a lot of ressources ;-( Make only one Zope tree, with only one database. Create a folder in the database for each user, and make each virtual server map '/' to the user folder. I tried this, but I had big problems caused by the fact that '/' is not /user_folder :-( Is there something possible with ZServer (without Apache)? Is there some "virtual server" implementation (making a database for each user, or all users in the same database)? Some time ago, I saw a thread about a variable "INSTANCE_HOME", what is it about, and is it implemented in V.1.11 ? Thanks, Luc

RE: [Zope] Iterating over items returned from external methods

Note however, that there are subtle differences between using a method by name (no quotes) and calling it in an expression (quotes). I got bit by this just the other day, and I'm still not 100% on the full behavior (I'm sure someone here will correct me if I'm wrong). Lets say you have your Method, and it returns a list:  <li>  Calling it by name the very first time you use it in your DTML Method|Document will cause the results to get cached and bound to the name 'Method'. After DTML rendering engine execute 'Method', it then turns that object into a sequence object (or a mapping if you specified the 'mapping' #in tag attribute). At this point, "Method" is no longer callable. So:       Will raise an exception at the second #in expression. This is nice if 1) Method does not require any arguments, and 2) Method is an computationally expensive procedure (like searching a large external database of some kind). This behavior happens for all callable objects, not just External Methods. Python Methods, ZClass Methods, and others will behave similarly. So the point is, be consistent in your usage of Methods in DTML. If the cacheing behavior breaks something of yours, use the expression syntax (quotes) as expressions are never cached. -Michel > --- Ben Derstine <bend(a)ecollege.com> wrote: > > I have an external method that returns a list call > > List.
