[Zope] [ANN] Zope 2.8.0 released
Hi all, on behalf of Zope Corporation and the Zope community I am pleased to announce the release of Zope 2.8.0. You can download Zope 2.8.0 from http://www.zope.org/Products/Zope/2.8.0/ Some new features of Zope 2.8: - ZODB 3.4 with MVCC (multi version concurrency control) support. MVCC solves nearly every problem with ZODB read-conflict errors which is very important for high-traffic Zope sites. - Extension Classes were rewritten as Python new-style classes making all features of Python new-style classes available in Zope objects. This includes support for cyclic garbage collection. - Integration of Zope 3 technologies through Five (see http://codespeak.net/z3/five/) For more information on what is new in this release, see the CHANGES.txt files for the release: http://www.zope.org/Products/Zope/2.8.0/CHANGES.txt See also: http://www.zope.org/Wikis/DevSite/Projects/Zope2.8/OverView **WARNING:** Due to the major changes in Extension Classes and ZODB there is a risk that some things are broken or do not work as they should. Backup your Data.fs **before** trying 2.8.0b2. Please bring all the bugs you have found to the Zope bugtracker: http://collector.zope.org/Zope":http://collector.zope.org/Zope For more information on the available Zope releases, guidance for selecting the right distribution and installation instructions, please see: http://www.plope.com/Books/2_7Edition/InstallingZope.stx Thanks to everyone having contributed to this release (hopefully I did not miss any names): Jim Fulton, Christian Theune, Tim Peters, Fred Drake Jr., Marc Hammond, Sidnei da Silva, Tres Seaver, Stefan Holek, Chris McDonough, -- Andreas Jung(andreas at zopyx dot com) pgpizFJrEnQ3H.pgp Description: PGP signature ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Re: aggreagating and merging logs under Zope 2.7.X
Well, I am not really ready to address the "multiple concurrent writers problem across NFS" and all the issues it entails. I'd somehow dismissed the SysLog solution, but I can certainly configure to use it. Thanks for the pointer.

You get this type of Error when you try to store something
in the ZODB which is not picklable (Python's term
for "serializable"). Of course, you can store only
serializable things in the ZODB.

It is the easiest and most standard solution. But there is also an SSL enabled ZServer (as a third party product).

Maybe, you should file a bug report:
Undocumented security related features might be viewed
as security holes...
Especially, if something unexpectedly becomes possible...
However, I think, this one in not overly critical.

Everything, you can do via the ZMI, you can do in a script (or an interactive Python interpreter). This is more appropriate for all kinds of mass operations. To find out what you can put into your script, you have 2 options: * you look at the Python source The "undo" methods are for example implememented in "App.Undo.UndoSupport". * you look at the HTML source of the ZMI pages and see there how the ZMI performs the task. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
