> 4) mysql 3.23.38 Unless your using the experimental transaction support in MySQL, this could be caused by Zope's ConflictError. When a conflict is detected inside the ZODB, Zope automatically retires the request up to 3 times. If you make changes to a non-transactional database, those changes will be re-run up to 3 times. -Randy

Need more enlightenment on traverse hook and security
by Dirksen 21 Jun '01

21 Jun '01

Hi, Thank you, Toby Dickenson and Dieter Maurer, for your tips on my problem. It's cracked instantly! However, as a layman of python and Zope, I couldn't figure out the meaning of "MyObj(name).__of__(self)". What is '__of__' funtion? I can dig very little information about '__of__' from python's website. What's the difference between 'Acquisition.Implicit' and 'Acquisition.Explicit'? And why these two steps are required to solve my problem? Look forward to your enlightenment. Cheers Dirksen __________________________________________________ Do You Yahoo!?

Unable to manage/edit Zope
by Mark Snellings 21 Jun '01

21 Jun '01

I have Zope installed on two development systems in my office. On the second system when I go to "manage it" http://192.168.0.1:8080/manage, I get the frame on the left frame which shows the root folder and what's in it, but the main frame just shows me the "view" of "Zope Quick Start" instead of the contents of the root folder. I am unable to "edit" it. If I attempt to manage it from another computer in the office, everything comes up fine. Also, when I use this second computer to "manage" the Zope installed on the first computer, I have the same thing. It appears to me that it related to my IE browser, but I cannot figure it out. Any ideas? Thanks Mark

In this case I will disable the functionality that requires sessions, if the browser has joined a version. Is the proper way to check for a Version to look for a cookie named Globals.VersionNameName ('Zope-Version')?

rotating log file and maxsize?
by Capesius, Alan 21 Jun '01

21 Jun '01

If the rotating logger maxsize is 4M and the log reaches this size shouldn't a new log be opened? The server is locking with a TransactionError when the log fills. Restarting opens a new log file. The logs are filling because XRON is looping on a bad job. Any thoughts on how to keep the server from parking? # lg = logger.file_logger(LOG_PATH) # change to force log rotation lg = logger.rotating_file_logger(LOG_PATH, freq='daily', maxsize=4000000) Alan Capesius, MCSE/NTCIP+20 Technical Support Engineer Sysmex Corporation of America capesiusa(a)sysmex.com

CST, non-undoing Berkeley Storage, and Versions
by Randall F. Kern 21 Jun '01

21 Jun '01

When running Core Session Tracking with a Session Data Container in an Externally Mounted non-undoing storage, Versions stop working. If you join a version, you will get this error when committing a transaction that used CST: Error Type: Unsupported Error Value: Versions aren't supported Is there anyway this could be fixed? -Randy

Apache Virtual Host problem
by Chris Bruce 21 Jun '01

21 Jun '01

I am using the VirtualHost monster. Everything is working except when I try and go to siteroot: http://www.chrisbruce.com the index_html file is not showing up. Instead, apache is saying I don't have permission to view "/". I am not sure why this is happening, any ideas? Regards, Chris Bruce __________________________________________________ Do You Yahoo!?

The GPL talks just about _distribution_ of a product, or more precisely, about the rights of _others_ for distribution. I can distribute my products with any license I want, who should have a problem with that and what license may be violated? To cite the GPL: "You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License." and "Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. " and (from the GPL-FAQ): "Is the developer of a GPL-covered program bound by the GPL? Could the developer's actions ever be a violation of the GPL? Strictly speaking, the GPL is a license from the developer for others to use, distribute and change the program. The developer itself is not bound by it, so no matter what the developer does, this is not a "violation" of the GPL. However, if the developer does something that would violate the GPL if done by someone else, the developer will surely lose moral standing in the community. " I.e. I also can publish internet explorer specific javascript under the gpl (or vb-macros for that matter). and (also from the GPL-FAQ) "I'm writing a Windows application with Microsoft Visual C++ and I will be releasing it under the GPL. Is dynamically linking my program with the Visual C++ run-time library permitted under the GPL? Yes, because that run-time library normally accompanies the compiler you are using." The only problem I see is when someone (DC) wants to incorporate someone else's GPLed product together with zope, or when someone wants to modify someone elses GPLed zope product and distribute it. But I think even the second part isn't a problem, because the GPL says (under section 2, the "viral" part): "These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. " For me that means that as long as I distribute someone elses GPL'ed zope product without zope, it's ok. I guess that we all are in agreement that zope "can be reasonably considered independent and separate work in themselves". cheers, oliver

re: [Zope] How to find out how is logged in on an NT domain at given IP
by Erik Myllymaki 21 Jun '01

If you use loginmanager with your NT domain ACL as the usersource and validation, this would only require using: <dtml-var "REQUEST['REMOTE_ADDR']"> and <dtml-var "REQUEST['AUTHENTICATED_USER']"> Works well for me. -- Erik Myllymaki erik(a)pacific-shores.com
