Zope/IIS4.0 problems and a solution.
by Martijn Pieters 05 May '99

05 May '99

Hello Zopistas, I have found a solution to many of the problems that the IIS4.0/Zope combination brings. Microsoft prides itself on the clear error messages that IIS 4.0 presents, when the user makes a mistake. These error messages are implemented in the form of Custom Error handlers, that return a file, or URL to a user when a certain error occurs. This means, that when you forget to fill in an Id when you want to create, say, a new SQL Method, Zope's clear error message is replaced by IIS's totally irrelevant error message. Also, it completely breaks authentication when the user uses IE5.0 when trying to log into a secure area of the server. These Custom Error handlers are enabled by default. Luckily, the handlers can quite easily be switched off: Open the IIS website in the Management Console, and navigate to the folder you put the PCGI executable in. If you named your Zope installation 'Zope', it will be called 'Zope.exe'. Double-click on that file. A property page will appear. Select the 'Custom Errors' tab. Now, select every HTTP Error code in the listbox that doesn't have type 'Default', and click on the 'Set to Default' button for each one. This will disable IIS overriding the error message returned by Zope. Click OK, and voila, Zope is allowed to tell the world what it thinks went wrong. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-6254545 Fax: +31-35-6254555 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

Operation timeout under IE4.0
by Miller, John M. 05 May '99

05 May '99

Greetings and salutations (though after that spam-ed Test message of mine many of you may be ready to salute my butt into high orbit), I have a feeling this may be old ground, but luck has failed me searching the documentation and list archives. My server setup is: Zope 1.10.2 (binary release, Python 1.5.1, win32-x86). IIS4.0 I have no problem using Netscape to access and fully use the management screens. The problem arises when I use IE4.0. I get errors on the order of (I got this trying to add a DTML document, I also get a similar error when adding a DTML method) : Internet Explorer cannot open the Internet site http://pmatrix:9673/cgi-bin/ZopeDevel.exe/manage_addDTMLDocument The operation timed out. A couple of notes: 1) I don't seem to get this error when adding a Folder object. I'm not sure, but I only seem to have this problem with DTML documents and methods. 2) A proxy server is used on my local network for web access, but my IIS server is local and I'm pretty sure I've disabled the proxy for local access. Many thanks, John Miller

HEAD Requests
by Paulo Eduardo Neves 05 May '99

05 May '99

Hi, My Zope isn't accepting HEAD HTTP requests. I'm receiving 404 'Not Found' errors. GET requests work as expected. Is it usual or is a problem with my configuration? Is there any way to fix it? I'm using the source Zope 1.10.2 with Apache 1.3.3 in an AIX4.1 machine. This is very serious! Search engines robots usually first make a HEAD request and, just if the file has changed, makes the GET. If HEADs aren't working, my site won't appear in ANY search engine. regards, -- Paulo Eduardo Neves mailto:neves@inf.puc-rio.br PUC-Rio de Janeiro

copy error?
by John Eikenberry 05 May '99

05 May '99

Hey all, On my home installation of Zope (see below for system specs), I can't seem to cut/copy/paste. Whenever I cut or copy somthing it never sticks. The paste button appears on the screen refresh, but it disappears as soon as I go into another folder. And if I just hit the paste button while its there, I always get the error below. Specs: Debian 2.1 glibc2.0.7 linux 2.2.6 Zope binary distributioin 1.10.2 netscape 4.5 apache 1.3.3 w/ pcgi ! No clipboard data found. Ok (button) Traceback (innermost last): File lib/python/ZPublisher/Publish.py, line 877, in publish_module File lib/python/ZPublisher/Publish.py, line 590, in publish (Info: /img_orig/manage_pasteObjects) File CopySupport.py, line 150, in manage_pasteObjects (Object: Navigation) Copy Error: (see above) I haven't had this problem on any other machine. Has anyone else had this problem? Any ideas? BTW, I just tried with 1.11.0pre1 and it still doesn't work (the traceback is different, but basically the same error).

upgrading to 1.11
by Richard.Jones＠fulcrum.com.au 05 May '99

05 May '99

Last time there was a new Zope version, Anthony Baxter wrote: """Ok, has anyone thought about putting together an upgrade guide for upgrading Zope versions? Steps I'm undertaking: . install new version install ZServer into new version (hm, do I still need to update Folder.py?) . copying external methods and products from old to new installations . transferring bobobase. either by exporting the old one, and importing the new, or by just copying over the Data.bbb. The former is more of a pain, the latter means you lose any new stuff in the default bobobase. """ I tried copying my 1.10.2 var directory to the 1.11 installation and things broke. I also tried exporting the object (folder). Looking in the management screen, everything seems OK. When I tried to use my application I got:  So, what is the "true path to upgrading"? I looked in the ZDP's FAQ an all I found was a quote from DC saying that applications may be retained after upgrade. Richard

To further things a bit, check my last message to the list. Here's a paraphrased uname, if it helps: Linux --- 2.0.36 #1 Mon Mar 15 14:23:33 CST 1999 i686 unknown Running Zope 1.10.2, var is located at /tmp to get past nfs. Python version 1.5.1. Apache/1.2.6. Anything else you need? I'm having really weird problems now. Look at my 'span-is implication' message. I feel the EEXISTS is somehow tied in to the indentation thing. At least it is triggered by attempting to view the indented version of index_html. Any thoughts? Thanks again, Chris

Indentation Oddities, or 'I didn't expect a sort of span-ish implication'
by Chris Larson 05 May '99

05 May '99

OK, here's a weird one. Things have been going fine for the last few days, then all of a sudden the world collapsed. I've been indenting my DTML with straight 'tab' characters, working in Netscape. Not had a problem. Now, all of a sudden today, when I call things that are indented, Zope hangs, eventually (and I do mean 'eventually') returning a 'Document contains no data, and pcgi.log shows: 'pcgi-wrapper: Failed to start resource (118) lock error: EEXIST' I am using the same browser, working on the same code, but all of a sudden can't indent. (At least I think that's what is going on.) And example: The first example chokes Zope with this mysterious EEXIST, while the second version works great. What gives? (Again, it _used_ to work.) -------------index_html------------              -------------index_html------------              Thanks much, Chris Larson Changeling, Inc PS To further confuse matters, the following 'changelingMenu' works great as is, but the changeling_standard_footer dies if I indent the '<HR WIDTH=480>' with a completely different error (See traceback following changeling_standard_footer). ---------changelingMenu--------- <TABLE BORDER=0 CELLPADDING=0 CELLSPACING=0 WIDTH=480> <TR ALIGN=CENTER>   <TD VALIGN=MIDDLE> <A HREF=index_html?file_id=> <FONT FACE=ARIAL SIZE=-1> <BR> </FONT> </A> </TD>   </TR> </TABLE> <HR WIDTH=480> ---------changeling_standard_footer------ <HR WIDTH=480>  </CENTER> </BODY> </HTML> ---traceback--- Sorry, an error occurred.
