I had to install new zope instance first, then import old content via zexp & recreate manually all admins. Because when you change the running zope config in Zope 2.7.0 it has no impact on temp_folder - Sessions.fs is not created when the temporary storage was already in place. Lets see, next test will be on Monday, many users come only on working days. I also got many complatins from customer, so I wrote a test suite which is logging to a site each 2 minutes, and if there are problem, it sends emails to all of admins, so they come and restart zope. With prev. Transience, when this keyError appear, it was seen only by 1,2,3 users. With new Transience, when error starts to appear, nobody is able to see any page which uses Session - all sessions became broken. I am monitoring site now, and will tell you about the results. -- Alex V. Koval http://www.halogen-dg.com/ http://www.zwarehouse.org/

Conflict errors on BDBMinimal storage
by Gerhard Schmidt 19 May '04

19 May '04

Hi, whe are running portal unter zope2.7 with one zeo server and six frontend application servers. I have set up zeo to server two storages <filestorage main> path $INSTANCE_HOME/var/Data.fs </filestorage> <minimalstorage temp> envdir $INSTANCE_HOME/var/session </minimalstorage> temp should provide an shared session. But when is set up the frontends to use temp as /temp_folder, we see many ZODB conflict errors. The performance decreases and PosErrors appear quite often. Is there any why to get a shared session working.

Threads dying on zope 2.7.0 on one Zeo setup, ZServer exception
by Heimo Laukkanen 18 May '04

18 May '04

Hi ya, I noticed some weird bahivour that was bringing a setup down on our servers on testing installation. In our setup we create development sandboxes with makefile and in similar fashion also testing/production servers. Our testing/production setup has a little bit different config files where from standard config all the commented out lines have been removed. Also compared to development instances the instance home is in other place. Other than that setups are same. At the moment with testing setup under load test ZServer dies - leaving all but one thread at almost 0% cpu and that one thread working in high loads of 90%. Testing similar zeo-setup with development instances do not produce this. We are a bit scared on this, since we do not have clue on what causes following behaviour - and eventhough we see that we can get it to work, we would like to have an idea on what might be behind this - so that it does not bite our butt again. Below is log snip and traceback of the exceptions when other threads go down. In log-file we get: 2004-05-17T16:47:17 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.HTTPServer.zhttp_channel connected 127.0.0.1:47855 at 0x42fdb36c channel#: 589

When is the configuration read in Zope 2.7?
by Andreas Jung 17 May '04

17 May '04

During the product registration the ZReST product is imported. on the module level it contains default_output_encoding = getConfiguration().rest_output_encoding or default_enc I would inspect that at this point the configuration from zope.conf has been read and rest_output_encoding should be available but instead the following AttributeError occurs. Any ideas why?

can't resolve/follow up on collector issues?

Not sure what has changed on Zope.org but the account that I typically use to resolve/follow up on collector issues ("mcdonc") is no longer able to do so (it appears I no longer have access to do sol; I can browse and read the issues fine). Anyone have any ideas?

Announce: Reusable Zope Public License 2.1
by Jim Fulton 16 May '04

16 May '04

We have updated the Zope Public License (ZPL) to revision 2.1. ZPL 2.1 is reusable. It supports having a consistent license for Zope and third-party products without requiring 3rd-party developers to assign copyright to Zope Corporation. It is important that add-on products for Zope be released under the ZPL. Why? Two reasons: * The ZPL is a flexible license that supports both commercial and non-commercial use of the software. * If Zope add-on products are released under the ZPL, then users of Zope and the add-on products only have one license to worry about. Keeping track of many different licenses is a burden to users. For more information, see: http://www.zope.org/Resources/License Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

Zope 2.6.X, 2.7.x sesssion problems, please help (fwd)
by alex＠halogen-dg.com 14 May '04

14 May '04

I see Chris post at: http://mail.zope.org/pipermail/zope-dev/2003-March/019116.html As far I see, this bug still existing in Zope 2.6.4, Zope 2.7.0. Its strange because into Changes histore of Zope it seems to be fixed into 2.6.2: Zope 2.6.2 beta 2 Bugs Fixed * TemporaryStorage (which is used by TemporaryFolder, and thus the default sessioning configuration) no longer uses a "LowConflictConnection" database connection. This fixes a bug in which data structures used for session housekeeping data could become desynchronized; the symptom for this was KeyErrors being raised from TransientObjectContainer's get method. As a result, many more conflicts will be raised under high session load, but desynchronization will not occur. Could you please at least point me where I can dig to get it fixed? I will try to read Python code in Transience.Transience but I am not sure in my qualification in this area. Bug reported at zope.org as: http://zope.org/Collectors/Zope/848 but until now there were no comments which help me to fix this. may be something needs to be changed into my code? in the beginning of many scripts I have the following: request=container.REQUEST session=request.SESSION please give me a hint. Thanks. -- Alex V. Koval http://www.halogen-dg.com/ http://www.zwarehouse.org/

Release schedule for Zope 2.7.1
by Andreas Jung 13 May '04

13 May '04

Hi folks, I have updated the Zope 2.7 roadmap to reflect the release schedule for the Zope 2.7.1 release: http://dev.zope.org/Wikis/DevSite/Projects/Zope2.7/FrontPage/ReleaseSchedule 27 Note to Zope commiters: - Bug fixes on the Zope-2_7-branch and older branches (if necessary) are done using CVS. - Bug fixes on the Zope HEAD must happen through Subversion. Fixes on the former CVS HEAD are no longer acceptable. I would appreciate if every active developer would pick up a bug or two from the collector and fix it :-) Cheers, Andreas -- Andreas Jung -------------------------------- www.zopyx.com Software-Development and Consulting Andreas Jung
