Receiving Acrobat FDF POST requests?
by Joel Burton 02 Apr '02

02 Apr '02

Acrobat forms can generate HTTP POST requests containing an FDF file. 1) How can I access this FDF data? I don't see it in the REQUEST object anywhere? Is there a way to get to the raw request? 2) Has anyone written any code to parse FDFs? Thanks!

[HELP] Zope local roles and LDAP Groups
by Frdric Lemaitre 02 Apr '02

02 Apr '02

Hello, I use Zope / CMF / LDAPUserFolder for some Intranet sites. But i have a problem with LDAP groups : I have some Groups of users defined in my LDAP annuary ==> Ok I use these LDAP-Groups to define "local roles", in some Folders ==> Ok But it doesn't seem to work : If i define the local role "Manager" for the LDAP-group "Informatique", when a user "flemaitre" (from this group) is authenticated, he doesn't have the permissions that i have given to the group "Informatique" Have someone any idea ? Is there any easy way to use LDAP Groups in Zope ? Thanks in advance. PS : Excuse my english... Fred.

crashes, viability, etc
by Iago 02 Apr '02

02 Apr '02

I have to restart my zope server every 1-3 days; no clear reason for it, as it dies silently, simply failing to respond on port 8080. I'm running pretty vanilla, with a virtual host monster, very little content, and ZUBB installed with a grand total of one discussion area. I'm on solaris 2.8, if that matters at all. This kind of behavior isn't making a great case to me to recommend the use of zope commercially -- the only time I've come across zope commercially, so far, has been with a customer who (anecdotally, as a coworker is the one who deals with them) has regular problems with zope threads and so forth. That, I can chalk up to bad code... but in my case, with very little code in place, I can't see a good reason for the crashes (or dropping port 8080's, at least, which amounts to the same thing ... I haven't had much time to diagnose, as I'm often in a rush to get the server back running again) to be happening with that kind of frequency. I've seen it happen under pretty variable circumstances, too -- using the /manage interface to upload a file, for example, ended up with an non-running zope (nevermind that the file appeared to upload fine first, before the crashing, as it was there on restart). There's also been some that seemed to simply result from loading a page, or posting a message to the one zubb topic I've got (though I recognize that may be a subset of the file upload situation). This is disappointing, because I really like Zope's architectural notions. The philosophy is great, especially when I compare it with the more "procedural" mindset of coding in Cold Fusion, which is what I _do_ do, professionally. At this point, though, I'd rate CF as more robust -- sure, it crashes on Solaris occasionally (in fact, I'm running zope and cf side-by-side for comparison right now), but that I _have_ tracked down to bad code usually, and when it does, it often has the courtesy (out of the box) to restart itself. But I'd really prefer a more zope-style object-orientedism. That said, I'm looking for a few things, here: 1. Pointers as to how to diagnose an intermittent problem like mystery crashes; 2. Pointers as to whether or not someone has developed a similar auto-restart feature (see what I say about CF, above) for zope; 3. Anecdotes to counter the ones I'm getting from the workplace, and my own experience, on the subject of stability. Anything folks can offer on any or all of the above topics will be met with pleased interest by me; I'm here to learn. Thanks -- Fred Hicks <iago(a)iago.net>

dtml-comment?
by Dan Rusch 02 Apr '02

02 Apr '02

I have been away from Zope for about a year or so. I used to be able to comment out blocks of code with: <dtml-comment> code to commented out </dtml-comment> this doesn't work in the code below? <dtml-comment> <h2>Sibling Links</h2> <div tal:define="siblings here/siblings.py"> <ul tal:condition="siblings"> <li tal:repeat="folder siblings"> <a href="folder" tal:attributes="href folder/absolute_url" tal:content="folder/getId">folder id</a> </li> </ul> <p tal:condition="not:siblings"><b>There are no courses scheduled at this time.</b></p> </div> </dtml-comment> The code between the comment open and end tags is still displayed, what am I doing wrong? Zope Version (Zope 2.5.0 (binary release, python 2.1, linux2-x86), python 2.1.2, linux2) Python Version 2.1.2 (#1, Jan 25 2002, 13:17:56) [GCC 2.7.2.3] System Platform linux2 Thanks, DR

Opera 6 issues
by kosh＠aesaeion.com 02 Apr '02

02 Apr '02

I seem to be having a problem with opera 6 and textareas. I have some users that use opera 6 and when they edit a textarea sometimes the textarea gets truncated with the end of the being corrupted. Sometimes it also works correctly. I have not seen this issue with any other browser. I am going to try and setup some more debugging to figure out why opera seems to be doing it. I have not seen this behavior with opera 5 running under linux. Running with zope 2.4.3 with python 2.1 Designing and building web applications http://webme-eng.com

unix security patch
by notices name 02 Apr '02

02 Apr '02

Hi. I am trying to use the UNIX security patch by zigg last modified 2002/01/23. I am running zope 2.5.0 on Red Hat Linux 7.2, so I used Zope-2.5.0b3-unix-security.patch. I am new to both Unix and Zope. Nothing like a challenge, eh? Anyway, the patch utility ran without a hitch, and then I went back and changed the start script to add -u zope to start as my "zope" user. I get Cannot safely setuid without initgroups I ran the install script over again, and still get this error. In the instructions it says "you must run the build script" and refers to a c module. What build script? Won't the install script compile this module? I found something called initgroups.c and I believe I have a c compiler, because the command cc acts like it wants to compile something, but if I do cc initgroups.c, I get initgroups.c:28:20: Python.h No such file or directory and the initgroups.c looks a lot like python to me. But I don't know c. The only thing I know now is that I am over my head. Thanks for any help. Annie

Zope help
by Rengasamy, Samy 02 Apr '02

02 Apr '02

Hi Sven, Thanks for the help. I am going to finish the 5th chapter in the ZopeBook, downloaded from zope's doc site. I still have not found the info you have posted. Where did you acquire this info? I just want to make sure I am reading the right docs. Samy Rengasamy. Date: Tue, 2 Apr 2002 00:51:22 +0200 From: Sven Rudolph <sven(a)spaghetticode.de> To: zope(a)zope.org Subject: Re: [Zope] How to refer an object in a sub folder? Hello Samy. > How do I refer to 'index' in the folder 'java' from an object in 'tech'? > > <dtml-var java/index> ??? Try this: <dtml-var "java.index"> If you rename your file to "index_html" you can even do this: <dtml-var java> Please keep in mind, that you are dealing with objects in zope, _not_ files and folders. (Even if the management screens make you think this) If your browser looks for http://my.zopeserver.org/main/sub/sub1/anothersub/index_html this is similar to <dtml-var "main.sub.sub1.anothersub"> or <dtml-var "main.sub.sub1.anothersub.index_html"> Greetings Sven Rudolph

structured text
by A M Thomas 02 Apr '02

02 Apr '02

I'm into the idea of letting my web development clients edit parts their own sites using structured text, but have a question about it for the experts out there. Sometimes a line wants to start with a number but not be an ordered list element, for example, in an address. Is there an easy way to make this work? I read all the documentation I could find, but didn't see a way around this. It's rather important to me. What I'm working on is allowing clients to enter their contact information to be displayed as part of the footer on each page. Addresses and phone numbers go in there, obviously. They'll want to control what appears on each line, etc., so structured text seems ideal. Any help for this? Many thanks, Am
