Zope IOError messages
by Jérôme Loisel 01 May '01

01 May '01

Hello! After working on my website for a few hours, I sometimes start getting IOErrors from Zope in stupid_log_write. See the full message here: http://zope.levinux.org/ioerror.html This only happens when editing the site. Upon encountering this error once, all subsequent attempts at modifying the site (or even restarting Zope from the control panel) fail with the same error. Simply viewing the site, however, will continue working. This problem is does not crop up constantly, but it is not rare either. I work full-time on the website, and this IOError happens a few times a week. It seems to be happening more recently. (Maybe I should pack my database?) I would like to know why this happens and whether or not I can do something about it. The site is meant to be dynamic user-editable. I can manually restart the Zope server, but my users cannot. So this could easily turn into a big headache if the problem persists. Thank you very much in advance.

Stupid WEBDAV question
by Darin Lee 01 May '01

01 May '01

Zopatistas, Please forgive my "thickness" on this question. I have been trying to do editing via WEBDAV for quite some time and have never gotten it to work. If I use IE 5.5, select Open (as webfolder) with "localhost:8080" as the location - I can see the Zope root folder files - but I can never edit or save (if I do open the document for editing, it's a local read-only copy). It's almost as though I am opening the folder as "anonymous user" - with the Zope "view" permission only. I am working on Windows 2000 Professional - with an instance of Zope/Medusa running locally. So, how does Zope know who I am when I access via WEBDAV? Is it using my Windows credentials for authentication? Thanks in advance, -Darin Lee

Re: [Zope] XML-RPC over SSL

May you away, when you add the port after host explicitly. s =3D xmlrpclib2.Server("https://uid:password@host:443/") If it does not help, you will need to look into the source how the host part is analysed. May need a fix .... Dieter

SECURITY alert and hotfix release
by Chris McDonough 01 May '01

01 May '01

Hello All, Dieter Maurer uncovered a potential security issue yesterday that necessitated a hotfix release. This hotfix addresses an important security issue that affects Zope versions up to and including Zope 2.3.2. The issue is related to ZClasses in that any user can visit a ZClass declaration and change the ZClass permission mappings for methods and other objects defined within the ZClass, possibly allowing for unauthorized access within the Zope instance. We *highly* recommend that any Zope site running versions of Zope up to and including 2.3.2 have this hotfix product installed to mitigate this issue. - http://www.zope.org/Products/Zope/Hotfix_2001-05-01/README.txt - http://www.zope.org/Products/Zope/Hotfix_2001-05-01/Hotfix_2001-05-01.tgz

Zope and FastCGI installation
by John VanDyk 01 May '01

01 May '01

I'm trying to enter the world of Zope. I've got FreeBSD 4.3 running and I've installed the Apache port with mod_fastcgi. The reason I'd like to use Apache is that I'll have some large files (QuickTime movies) that I don't want to put into Zope. It sounded to me from reading doc/WEBSERVER.txt that fastcgi was the best way to go, as it permits Zope to run multithreaded and allows Apache to handle static files. Please correct me if I'm wrong on this. I've installed Zope 2.3.2 from source and it seems to have come up OK. I've done the modifications listed in WEBSERVER.txt and I get the message 2001-05-01T18:55:57 INFO(0) ZServer FastCGI Server (V1.0) started at Tue May 1 13:55:57 2001 IP : Port : None Socket path : /usr/local/www/Zope/fastcgisocket/fastcgi.soc when Zope starts so it seems to be ready. But when I point my browser at my.server.org/zope Apache tells me that "The server encountered an internal error or misconfiguration" and Apache's error log elaborates: [Tue May 1 14:17:01 2001] [error] [client 129.186.111.11] FastCGI: invalid (dynamic) server "/usr/local/www/data/zope": script not found or unable to stat() I think I've pretty much followed the instructions to the letter, but I must have missed something.

Hi Norman, Please keep the messages on the list. THere is 512MB of RAM on the server. How much RAM is your Zope process limited to?

This depends on your application, but Zope likes lots of RAM. How much memory do you have available now? Take that number and double or triple it, and see it it works then. ----- Original Message ----- From: "Norman Khine" <khine(a)btinternet.com> To: "Chris McDonough" <chrism(a)digicool.com> Sent: Tuesday, May 01, 2001 7:53 AM Subject: RE: [Zope] ERROR(200) ZODB FS FS21 > Yes, Chris, they do have a limit the processes, but was told that I can > unlimit this and once I did this they would inform me if any processes hogh > too much memory by e-mail.
