Auto-documenting Zope Products
by Antonio Beamud Montero 13 Dec '02

13 Dec '02

Hi all: I want to document all my products with pydoc. I have patched the source code to works fine with zope code and I have run the zdoc.py script, but zdoc.py fail's and said something like: Traceback (most recent call last): File "/usr/local/bin/zdoc.py", line 5, in ? import Zope File "/usr/lib/zope/lib/python/Zope/__init__.py", line 43, in ? DB=ZODB.FileStorage.FileStorage(Globals.BobobaseName,read_only=_isReadOnly()) File "/usr/lib/zope/lib/python/ZODB/FileStorage.py", line 200, in __init__ raise ValueError, "can\'t create a read-only file" ValueError: can't create a read-only file What can I do? Exists other tool? Thanks... -- Microsoft merges technologies: Windows CE + Windows ME + Windows NT = Windows CEMENT ---- Antonio Beamud Montero Agora Systems S.A. http://www.agoratechnologies.com

Page Templates
by Nuno Maltez 13 Dec '02

13 Dec '02

Hi, We're building a site using ZPT and we're facing a problem. The pages are in Portuguese, and therefore we have text in some attributes with character entities like for instance <img src="" alt="água"> This seems to be the correct HTML: http://www.w3.org/TR/html401/charset.html#encodings These tags don't have tal: attributes, however Zope always converts the character entity's ampersand into &alt;, rendering the above example as <img src="" alt="&aacute;gua"> which is nonsense. Is there anyway to prevent this? We're using Zope 2.5.1 Thanks in advance, Nuno

External Editor not updating content
by Tim Wilson 13 Dec '02

13 Dec '02

Hi everyone, I'm trying to get Casey's External Editor product to work, but I'm having trouble. I've configured the browser and clicking the icon opens the file just fine, but when I save the file and exit the editor the content never gets updated on the Web. One other thing I notice is that when zopeedit.py starts up, I get a quick flash of a window that pops up and disappears in a split second. I have no idea if that window is presenting an error message or what it is. I'm running Zope 2.6.0 on Debian and my workstation is SuSE 8.1 with Mozilla. Any suggestions? -Tim -- Tim Wilson Twin Cities, Minnesota, USA Science teacher, Linux fan, Zope developer, Grad. student, Daddy mailto:wilson@visi.com | http://qwerk.org/ | public key: 0x8C0F8813

Zope 2.6 and ZEO 2
by Vladimir Petrov 13 Dec '02

13 Dec '02

I have some problems with setup Zope 2.6 and ZEO 2. I have ZEO on one machine and ZEO client on the other. I'm starting ZEO and logs with daemontools, and ZEO is up and running. Also client is monotired by daemontools and its working. In a log on ZEO side, I got reported connection (over tcp) and client create .zec file and everything looks just vine. But, when I do on ZEO client (echo -e "GET / HTTP/1.0\n\n"; sleep 5) | telnet 217.144.227.147 80 I get connection, html of quick page and connection is closed by ZEO client. When I try once more, I get nothing just closed connection. There's nothing in a log files neither on ZEO or on ZEO client machine. I have to mention that the simmilar setup, but on single macine with a socket instead tcp for connecting ZEO client with ZEO, working just fine... Anybody have any idea what's happening, or some links where I can read about it? Vladimir

Internet Explorer, Manage, Port 80
by Robert Roberts 13 Dec '02

13 Dec '02

Has anyone else seen this problem and/or does anyone know a fix. If I run Zope on port 8080, I have no problem logging in to manage the site (e.g. http://localhost:8080/manage) If I put Zope on port 80, I cannot log in to manage the site (e.g. http://localhost/manage or http://localhost:80/manage) when using Internet Explorer only. I have no problems when using Mozilla, Phoenix, or Opera. I get the log in screen. Enter my UID and PW and the browser just goes away (thinking) for eternity. I have tried IE 5.0 and IE 6.0. I am running Zope Version (Zope 2.5.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) running on Win2K. Thanks, __________________________________________________ Do you Yahoo!? Yahoo!

Sessions and the temp_folder
by Chris Muldrow 13 Dec '02

13 Dec '02

Now that I've got sessioning backed by Berkeley Storage via various howtos, my session data container lives in a Berkeley-backed folder in the root of my zope called session_storage. The default temp_folder that Zope creates is still sitting in the root of my zope with the default data container inside. Is that folder sucking down RAM and using resources, or does it just sit happily if the session data manager isn't making calls to it? I ask because it won't stay deleted if I use an external method to kill it--it returns like a bad fungus when I restart a Zope client.

running v2.6 as root on Jaguar
by Phil Schumm 13 Dec '02

13 Dec '02

Hi, I have for some time been running Zope 2.5.1 on OS X. I have been using a startup script to launch Zope automatically (i.e., as a Mac OS service), which means that I am starting it as root. Following the advice I have read, I set up a restricted user called "zope", and am using the -u flag in the start script to have Zope change to user "zope" after it is launched. Indeed, when I view the active processes (e.g., using the ProcessViewer application), I see that one of the two has switched to user "zope." Recently, I installed Zope 2.6 on a new machine running Jaguar (i.e., OS 10.2). Following the instructions in doc/SETUID.txt, I changed the owner of var to root, set it's sticky bit, and added the -u flag in the start script (i.e., -u zope). Zope starts fine (and works fine), but now when I look in the ProcessViewer, it appears that both Zope processes are still running as root. Does this mean that Zope is not actually "setuid()"ing correctly to the user I have specified with the -u flag? Am I overlooking something obvious here? Thanks for any insights, -- Phil

Zope auhtentification with Apache
by sophie seillier 13 Dec '02

13 Dec '02

Hi, I work for a company which wants to integrate Zope and still use the web server Apache. I have to do tests to validate this way, and I have problems.... I have no problem to access Zope pages when there isn't authentification, but I don't manage to delegate the authentification to Zope, and I can't access the Zope "manage" page. I follow the Zope documentations' instructions whitout success. I modified the httpd.conf file with : RewriteEngine On RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope(.*) /var/www/cgi-bin/Zope.cgi/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] where - the "RewriteRule" line is one long line - /var/www/cgi-bin is the "cgi-bin" directory of my Apache server. (the mod_rewrite is loaded by my Apache server) I have installed : Zope 2.6.0 Apache 2.0.40 on RedHat 8.0 I don't find interested logs about this login failed... Where can I find log about it ? I could'nt use Zap ton resolve my problem... I have to use the existing Apache server Web... I know there is an alternate way : recompiling the server with the flag -DSECURITY_HOLE_PASS_AUTHORIZATION. But I don't know the impact of this way on a production platform... Are all the configurations failed ? What are the instructions to recompile the Apache server ? Could you help me to resolve my problem please ? Thanks for your help Sophie.

Re: [Zope] global variables in externa Methods
by Elena Schulz 13 Dec '02

13 Dec '02

Hi Paul, I want to pass many vars to some other functions of the same py-module than that connected to the external method. If possible not as explicid args as there are many and they dont' change while processing. Could be global constants, too. By the way, is it possible to interrupt the processing of external methods without shutting down the server? -- many thanks for your replies, Elena You wrote: Stop right there... that's a syntax error in Python: SyntaxError: name 'var1' is local and global What are you really trying to do? Why do you pass a parameter to myFuntionA and then try to make the name of the parameter (which is local to the function by definition) a global? --PW

Pilot, a navigational aid for ZMI coders
by Ausum Studio 13 Dec '02

13 Dec '02

Pilot is a simple tool that generates floating menus of a site's folder structure and content, callable by double clicking ZMI's pages. Aimed to CMF portals, I've been using this helpful aid since a long while ago, and now I'd like to share it with the community. I'm currently using it to quickly reach folders, methods, favorites and recent objects, but it can be hacked to become a standard navigational aid for the CMF. Problem is that it uses a javascript menu that is licensed, but it's likely that now there are some other free ones than can be used instead. If anyone knows of any reliable, please let me know so that I can perform the changes and then release the code. More details at the screenshots page.
