[ZODB-Dev] [Enhancement Proposal] Garanteed lifetime for volatile variables
I have put an enhancement proposal at http://www.zope.org/Wikis/ZODB/VolatileAttributeLifetimeGarantee It allows applications to declare that they need for some (so called sticky) objects a garanteed lifetime for their volatile attributes that extends until at least the next transaction boundary. This extension makes safe the use of volatile attributes for the following cases: * the storage of database connections in Shared.DC.ZRDB.Connection * the former use of _v_skindata in Products.CMFCore.Skinnable (now replaced by a much more complex, less efficient and not completely correct solution) * the use of _v_is_cp in Archetypes.BaseObject (and other use of volatile attributes for control purposes). This statement implies that the current use is unsafe. Feedback is welcome -- either in the Wiki or here. -- Dieter ___ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
[ZODB-Dev] HOWTO recover from Data.fs.tmp
Hi, I have, Plone 2.1.2, Zope (Zope 2.8.6-final, python 2.3.5, linux2), Python 2.3.5 (#1, Apr 11 2006, 16:55:30) [GCC 3.3.5 (Debian 1:3.3.5-13)], For some reason zope stop writing at Data.fs about a week ago. Now i have a Data.fs with 1 week older data and a Data.fs.tmp with, I hope, the new data... How can I mix those data files? I read somewhere about just do a cat Data.fs.tmp Data.fs, but this doesn't work... after that fstest complains about time-stamp reduction Why zope keeps writing in .tmp file if he can't rebuild data file from there? Thanks...

I've seen an informal version of this by Dieter on a mailing list somewhere (might even have been this list) ages ago and even thought that it was already implemented. I really like the proposal, +1 on it. -- Sidnei da Silva Enfold Systemshttp://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214 ___ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev

I've seen an informal version of this by Dieter on a mailing list somewhere (might even have been this list) ages ago and even thought that it was already implemented. It is implemented in our (local) copy of Zope since about the beginning of 2005. I have put patches into the collector -- but they never made it into the core (and patches tend to break, when they are not incorporated soon). I am now a Zope committer and can directly work on the core -- thus patches are no longer needed. -- Dieter ___ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org http://mail.zope.org/mailman/listinfo/zodb-dev
