NEWBIE QUESTION: Receive TypeError when scheduling Xron events
by Dwayne Morrison 08 Sep '00

08 Sep '00

Hello, I'm having trouble scheduling events with Xron 0.0.9. I try to create a scheduled event as described in the doc: <dtml-with "manage_addProduct['Xron']"> <dtml-call expr="manage_addXronDTMLMethod( this(), 'SchedMethodId1', 'Scheduled Method 1 Title', file = 'Content-Type: text/plain\n\nBANG!!!', executeAt = _.DateTime()+14 )"> </dtml-with> When executed within a DTML method, the code reports this error: Error Type: TypeError Error Value: keyword parameter redefined I found that the 0.0.9 version of Xron added a new parameter, periodDays, to the method. Adding that produced the same error message. I tried naming all parameters also to no avail. Any suggestions would be greatly appreciated. Environment: Zope version: Zope 2.2.0 (binary release, python 1.5.2, solaris-2.6-sparc) Thanks in advance, Dwayne Morrison dcmorrison(a)tidewater.net

I actually found that file by a quick grep through the source. Im not sure I understand what you are trying to do with the management interface there, and with more information I cannot help you. ----- Original Message ----- From: "Mechtild Hofmann" <konteXXt(a)t-online.de> To: "Andy McKay" <andym(a)activestate.com> Sent: Friday, September 08, 2000 1:10 PM Subject: Re: [Zope] manage_workspace > Hello Andy, > > thank you, that was the file I am looking for. > Where can I read such things ? > > I want to create a management-interface to add Links and News outside > the Zope-Management-Screen.

repost : pb with acl_users "domains" for clients behind a proxy/firewall
by Didier Georgieff 08 Sep '00

08 Sep '00

Hello, I'm reposting here, since i couldn't solve this strange problem. Our users are acessing to the Zope server (wich is on the Internet) thru corporate (government) firewall/proxys. Some users in acl_users are declared with a "domain" restriction. wich is a generic "gouv.fr" or "agriculture.gouv.fr". It doesn't seems to be effective and the login is rejected, while the same user without any "domain" restriction works fine. I'm suspecting some changes in the REQUEST made by the corporate proxys. Is there any doc about what REQUEST variable is used in the "domains" restriction ? I have a HTTP_FORWARDED in the REQUEST but with the *proxy* name (unfortunately without the .gouv.fr). I can't find anything on the site and the list either.Thanks in advance. Didier Georgieff.

NEWBIE HELP can not get Zope to start
by Douglas Eadline 08 Sep '00

08 Sep '00

I have tried this 10 times with several versions of Zope and I get the same result - Zope will not let me add a user or log in. Here are my steps: 1. download and install latest RPMS: Zope-2.2.1-1.i386.rpm Zope-zserver-2.2.1-1.i386.rpm 2. Start zope: /etc/rc.d/init.d/zope start 3. login as superuser superuser 123 4. See first Zope Screen 5. Attempt to run the tutorial as described in the Content Managers Guide Zope will not let superuser do this 6. OK, I'll add a user. I go to acl_users and add a user. 7. I quit netscape, and restart and attempt to login as the new user - DOES NOT WORK 8> I check /var/zope/access - no new user added 9. I quit netscape and re-login as superuser. I look at the user I added, now the password field has more stars in it than the password I assigned. The confirm field has 1 star less than the password field. I do not get it. Is there something to read that explains how to start Zope and try the tutorial? Or is this some secret only Zope hackers know?

OSError along with FSSession...
by Chien-Pin Wang 08 Sep '00

08 Sep '00

Dear Zope Users: I have upgraded to FSSession 0.4.2 lately and occasionally run into the same problem several times. Each time it costs me a zope down. I do really need some help... Zope complains an error type "OSError" and throws the error value saying [Errno 21] Is a directory: '/usr/local/zope/var/FSSession/' occasionally since a recent upgrade of FSSession product to 0.4.2. Following that error will be a series of TransactionErrors for each and every request Zope received. And only a zope restart could help zope resume its operations. Since this error only comes up occasionally, I'm completely clueless on solving it. My environment is RedHat Linux 6.2 + Zope 2.1.6. The traceback information looks like this... Traceback (innermost last): File /usr/local/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 169, in publish File /usr/local/Zope-2.1.6-src/lib/python/ZODB/Transaction.py, line 275, in co mmit File /usr/local/Zope-2.1.6-src/lib/python/Shared/DC/ZRDB/TM.py, line 120, in t pc_finish (Object: TM) File /usr/local/zope/lib/python/Products/FSSession/FSSession.py, line 87, in _ finish (Object: TM) File /usr/local/zope/lib/python/Products/FSSession/FSSession.py, line 208, in final_commit (Object: FSSession) OSError: [Errno 21] Is a directory: '/usr/local/zope/var/FSSession/' Any help will be very appreciative!

Re: [Zope] Lock and Transaction in Zope.
by Hung Jung Lu 08 Sep '00

08 Sep '00

Hi Aitor, (I am posting to the Zope mailing list, too.) >I have Zope in W2000 >Zope 2.2.1 >Internet Explorer 5.0 Ok. I just tried with Zope on Linux, after I tried with Zope on Windows 98. RedHat 6.2 Zope 2.1.6 Internet Explorer 5.0 Guess what? The thread did not hang. The long thread returns, but the value of your "var" was 2. The situation is then: (1) For Zope running on Windows, the long thread hangs and never returns anything to the browser. (2) For Zope running on Linux, the long thread gets into transaction conflict. But Zope was smart enough to abort the transaction and restart the request again. (Just like what other people said.) I think this should be considered as a bug in Zope for the Windows platform. We should submit the bug report to the Zope bug collector. Notice that it happens for Zope 2.1.6 and Zope 2.2.1, I wonder why no one has reported this bug... (or has it been reported but not been fixed?) regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Set Access Rule wish
by Albert Boulanger 08 Sep '00

08 Sep '00

Its nice that the icon for the method, who is the access rule's target, is changed. However, I think also there needs to be some indicator on the folder involved as well. Over the long weekend, I had accidentally set an access rule (for URL-based SQLSession ID) in the proper folder and also a subfolder (to the same method). Took me several days to discover that other access rule had been set in the subfolder. When your you have mistakes with this kind of stuff, I can be madding and any kind of indicators would be useful. Regards, Albert Boulanger aboulanger(a)vpatch.com
