Here's a brief review (ZDNet) of Interbase, PostgreSQL, and MySQL. http://www.zdnet.com/pcweek/stories/news/0,4153,2436153,00.html General consensus is, for high-read / low write, MySQL is fastest, but in a dynamic environment PostreSQL shines. Some caching issues with the current Intebase for Linux hampers performance, but that should be resolved as things evolve. Here's a thread from /. with some good discussion. http://slashdot.org/askslashdot/99/08/10/0416205.shtml

where has the REQUEST-object gone???
by Andy Pahne 08 May '00

08 May '00

hi, at the moment we are builduing a database-enabled three-language website. we have the contents (texts) for the site already in a database. I wrote a Z-SQL-Method sql_get_text which takes id_to_get as argument. So, when I call <dtml-in "get_text(id_to_get=xxxx)"> <dtml-var text_value> </dtml-in> I get the text I was looking for. (Note that this ZSQL-method will return only one result, because id_to_get is the primary key of the database table and therefore unique). I wanted to make things a bit easier for the people who generate the templates for the site. So I coded a helper-method named get_text which also takes id_to_get as argument. It holds exactly the code-snippet from above. By doing so I wanted the HTML-Coders to type <dtml-var "get_text(id_to_get=xxxx)"> so that they do not have to worry about the dtml-in-tag. It did not work. I get an error-message that Zope can not find the ZSQL-method sql_get_text method. Here is the traceback: Traceback (innermost last): File /usr/local/src/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/src/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/src/Zope-2.1.6-src/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/src/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/src/Zope-2.1.6-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: content) File /usr/local/src/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: content) File /usr/local/src/Zope-2.1.6-src/lib/python/OFS/DTMLMethod.py, line 150, in __call__ (Object: content) File /usr/local/src/Zope-2.1.6-src/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: content) File /usr/local/src/Zope-2.1.6-src/lib/python/DocumentTemplate/DT_Util.py, line 335, in eval (Object: _['content-ms']) (Info: _) File <string>, line 0, in ?

But then I received and error-message telling me that I am trying to refference the non-existing object REQUEST. Now, why doesn't it find my method and why did the REQUEST-object disappear??? PS: I am doing Zope for half a year now but the namespace-stack is still mysterious to me.

non static size parameter in dtml-var
by Scott Parish 08 May '00

08 May '00

I have a dtml-var tag that is being repeated over and over inside of a dtml-in tag. I would like the client to be able to custimize the maximum amount of text output they see, so i did something like the following: <dtml-var "item['title']" size="getTitleLen()"> Where getTitleLen is a method which returns an integer of how many characters max the title is to be. However, when i have this dtml method rendered, i get the following error: a size attribute was used in a var tag with a non-integer value. Is there a do what i am trying to do? If so, how could i do it? If not, why isn't this possible? thanks sRp -- Scott Parish http://srparish.net

Re: [Zope] IE Auth failures, NS works fine

Under Internet Options, Security I run under the Internet web content zone. Clicking on the Custom Level button I have User Authentication, Logon, Automatic Logon only in Intranet Zone set, I also have all the Scripting options enabled,Userdata persistence enabled, submit nonencrypted form data enabled,software channel permissions at medium safety, navigate sub-frames across different domains enabled, launching programs in an IFRAME enabled, installation of desktop items enabled, drag and drop enabled, access data sources across domains disabled, cookies enabled (both options). I can't see anything else there that may be relevant I'm accessing this via an NT-based proxy server called WinGate which clearly causes no problems. Something at the back of my mind is nagging - to do with the encryption of passwords in NT (introduced in one of the service packs). I know this can cause issues with people running Samba on Linux and there is a script which you can run (supplied with Linux somewhere) which patches the Windows registry to turn off encryption. I have run this script myself. Might it be something to do with this ?? HTH Richard At 07:22 08/05/00 -0400, you wrote: >That would be great if you could pass on the IE settings.

strange pcgi prob in FreeBSD
by thomas＠hentschel.net 08 May '00

08 May '00

Hi all, While trying to update the zope port for the FreeBSD ports system I ran into a problem which kinda has me stumped. I looked thru the ML archives, but couldn't come up with anything, although I'm sure this has happened before. Everything runs normal when I just connect to ZServer. Running it thru Apache I get (sometimes): Temporarily Unavailable The resource you requested is temporarily unavailable - please try again later. (116) unable to connect, fd=4  on *some* documents. I.e. the ZopeButton in the default page will show this, but not the page itself. In the /manage screen, the left frame will be ok, but some of the right frames will show this behavior, while others won't. It seems ( I actually confirmed this) that it depends on the file size being served. I can make the left tree frame display "Temporary Unavailable" too if I open enough sub-tree elements. Here is the setup info : falcon# uname -a FreeBSD falcon.home.hentschel.net 3.4-STABLE FreeBSD 3.4-STABLE #1: Mon Apr 17 18:22:53 PDT 2000 thomas@falcon.home.hentschel.net:/usr/src/sys/compile/FALCON i386 Python 1.5.2 (#2, Jan 19 2000, 17:09:29) [GCC 2.7.2.3] on freebsd3 Zope-2.1.6 Any hints with that would be highly apreciated. Thanks -Th

I'm running Zope 2.1.4 with GUF using Zserver on RedHat 6.1 and I have had no trouble using IE5 on NT4 workstation. Does this point to the Apache to Zope connection being the problem - is the authorisation being passed through correctly ? Have you tried it with Zserver to see if it works in that mode ? I'll happily pass on my IE5 settings etc. Richard At 10:04 01/05/00 -0400, you wrote: >Please excuse my ignorance in this matter.

HELP!
by Brown Fox 08 May '00

08 May '00

Help! I've just started learning Zope and i have to do quite an interesting work: my task is to create an intranet server for publishing internal documentation in PDF format. The user will have a tree to browse. Single record contain properties and several files (PDF). Problems come from the security: each user will have a Priviledge that is an integer number. This number will be compared with records AND files in it. So, for example i can see a record but not all the pdf files describing it. What i needs are suggestions: do you think that the Zope internal database will hold up to 2000 pdf files (50 to 150K each)? I've written the user login/logout with GUF, adding the priviledge value but how i can compare it with files?

dtml-tree bug?
by Ondrej Palkovsky 08 May '00

08 May '00

Hi, I was just testing some things with Zope and came probably across a bug: This works (I don't want the 'Catalog' to appear in the list): <dtml-tree branches_expr="objectValues(['Folder'])"> <dtml-var id> </dtml-tree> Unfortunately calling this page with '?expand_all=1' causes the thing to fail on 'KeyError', 'branches'. I tried some hacking but the only result I got was an always collapsed tree. Is this a known error? Ondrej -- Love is staying up all night with a sick child, or a healthy adult.

Thanks you for writing. I have been thinking that I am losing my mind. I have the same trouble with IE5. IE3 and IE4 work fine. No one has replied to this thread and I have made no further progress. It is very annoying. Let's compare our setup and see if we can figure this out together? I'm running Redhat 6.1 with Apache serving Zope. Auth is via GUF. I was thinking it may be something the do with the Auth Realm or something. I really don't even know where to start because people think I am trying to start a flame war when I say that IE5 seems to be the problem. I've already started porting to Enhydra because no one can help me. Please, write me and let me know if you find anything out. thank you jim Ingo Assenmacher wrote: > > Hi Jim. > > I am encountering the same problem.
