Text only pages
by John Hile 10 May '00

10 May '00

We have a page on our site that is intended to return plain-text only -- no html. The page consists of a dtml method that calls a single External method which, in turn, returns plain text read from a file. The page is read by a small client that uses HTTP to access the site. Since the file that the text comes from can be any file, it may, itself, contain html code. We've found that, in certain cases, if the plain text happens to include html tags, Zope will insert an empty html header at the beginning of the page. It contains only "<html><head></head>". We've tried setting the content type in the RESPONSE header to "text/plain", but it has no effect. Anyone know what's going on and how we can suppress it?

RE: [Zope] ZLDAP 1.0 beta 2
by Jeffrey Shell 10 May '00

10 May '00

Alright. What is happening is that this is failing non gracefully when it can't retrieve the base entry. This will be handled better in the next beta and/or final release of current snapshot which may happen this week. There is now a Wiki in the ZopeLDAP Product that will start to collect some documentation and how-to's. It will also be a capture point for future directions. http://www.zope.org/Members/jshell/ZopeLDAP/ZopeLDAPWiki/FrontPage > -----Original Message----- > From: Petr Knapek [mailto:knapek@knapek.pvt.net] > Sent: Wednesday, May 10, 2000 6:20 AM > To: zope(a)zope.org > Subject: [Zope] ZLDAP 1.0 beta 2 > > > Hi Jeffrey, > I tried to install your product ZLDAP on my Zope 2.1.6 (Debian Linux > box).

Preview Release: ZUBB (Zope Ultimate Bulletin Board)
by J. Atwood 10 May '00

10 May '00

http://www.zope.org/Members/BwanaZulia/ZUBB/ This is my pre-release test of ZUBB (Zope Ultimate Bulletin Board) which is based heavily on ZDiscussions. Before I announce it on Zope.org (or before Ken posts it to ZopeNewbies.. Not yet Ken. <grin>) I would like a few more people to try downloading and installing it. Test Board: http://www.bwanazulia.com/kenya/discussions/test/ Feel free to bang away at that. Basically I took ZDiscussions, ripped out ZConfera (or the product anyway), added a bunch of features to it and put it back up under the ZUBB name. I will rename the full product and all of pieces soon, but for now since a few people have wanted to get their hands on it I am putting it up in its "green" form. Please send feedback to this list. Thanks, J

How big is a folder in ZODB
by Richard Moon 10 May '00

10 May '00

Is there any way to see how much space a folder and its objects and sub-folders takes up in the ZODB ? I want to offer Zope hosting services but I can't see how I can establish how much space a client is using. I need a du command for the ZODB I reckon ! Any ideas ? Thanks in advance.

ZLDAP 1.0 beta 2
by Petr Knapek 10 May '00

10 May '00

Hi Jeffrey, I tried to install your product ZLDAP on my Zope 2.1.6 (Debian Linux box). I can open connection to an LDAP server and to get search results when an LDAP method is used. That's no problem. What annoys me is this Zope error message when I try to make LDAP connection object browsable in manage mode (browse tab): Zope Error Zope has encountered an error while publishing this resource. Error Type: IndexError Error Value: list index out of range Traceback (innermost last): File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: mm) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/ZPublisher/Publish.py, line 165, in publish File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_browse) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_browse) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_browse) (Info: /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/Products/ZLDAPConnection/browse.dtml) File /home/knapek/dist/zope/Zope-2.1.6-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: manage_browse) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 132, in render (Object: getRoot) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/Products/ZLDAPConnection/ZLDAP.py, line 248, in getRoot (Object: mm) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/Products/ZLDAPConnection/ZLDAP.py, line 238, in getEntry (Object: mm) File /home/knapek/dist/zope/Zope-2.1.2-linux2-x86/lib/python/Products/ZLDAPConnection/ZLDAP.py, line 228, in getRawEntry (Object: mm) IndexError: (see above) Below you can see part of syslog (LDAP log), when I tried to switch to browsable LDAP connection and have a click on 'browse tab' in manage screen.

Can ZServer run CGI directly?
by Quentin Stafford-Fraser 10 May '00

10 May '00

I'm wondering whether Zope can run CGI programs directly without the use of Apache? ZServer seems adequate for our needs, and it seems a bit messy to run a whole Apache just to get the output from a couple of C CGI programs. I suppose I could do something with os.popen(), but I wondered if there was a better way?

What's the idea behind the insertBase(...) in HTTPResponse ?
by Martin Grönemeyer 10 May '00

10 May '00

In some cases the HTTPResponse-Object adds an "<base href=....>" to your HTML-Output. For some reasons (virtual hosting with an ip-based caching and different domains for the same ip) i would disable this mechanism. It's easy to comment the insertBase(...)-Method in the HTTPResponse-Object but I've no idea of the side-effects. Has anyone some experience with this ? Martin
