[Zope-dev] Zope 2.8.1 final
Heads up for the upcoming Zope 2.8.1 final release. I will cut the release on Thursday this week. This will be - as the name says - the final release so there won't be any further beta releases. So fixes and whatever must be commited before Thursday. Depending on the number of fixes that will happen after the 2.8.1 release I will focus on a 2.8.2 release in mid-October (after a longer vacation :-)).

RE: [Zope] Data.fs Windows to Linux?
I had a similar issue when playing with Data.fs files, and I found that it was a write permission issue on the file. Don't know if it can help you in that case. Pascal -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Marc Schnapp Sent: 06 August 2005 01:14 To: zope@zope.org Subject: [Zope] Data.fs Windows to Linux? I thought that I would back up my data.fs by copyting the entire Linux /var directory to a Windows machine with spare disk space and then creating a ZIP file on the Windows machine. There was a problem on the Linux machine, so I figured there'd be no problem by simply copying the data.fs (via a Samba share) back from Windows - Linux.

The Same Database File Works Perfectly With A Windows Plone/Zope Installation - I installed a Windows version of Plone (with Zope of course) and that same data.fs file works just fine in the Windows environment. Questions: 1) Am I without hope of ever running the database under Linux again? 2) What is the reason that the database goes from Linux - Windows OK but not in the other direction? 3) MOST IMPORTANT: Is there a technique I can use to tweak the database file or recover it so that it is Linux-friendly? ___ 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 ) ** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

If you are using a cmf based product (like plone) you must check if the skin path stored in the portal skins are still ok. In my time they where stored as an absolute path wit C:\ and /home/zope.. on windows/linux which had to be fixed (there is a script on zope labs which can do that for you).

Re: [Zope] Zope 2.8 and conflict errors
Not correct. _p_resolveConflict is used in Zope 2.8.x (and in Zope 3) exactly the same way it was used in 2.7.x. If it's not working, there may be a new bug in 2.8.x, but there's been report of that yet. Because of errors like: ConflictError: database conflict error (oid 0x0299de, class Products.DCOracle2.DA.Procedure, serial this txn started with 0x035f0726c7bfca88 2005-08-01 08:38:46.816215, serial currently committed 0x035f072fed78ebee 2005-08-01 08:47:55.657582) and according to: http://www.upfrontsystems.co.za/Members/jean/conflicterrors-explained I've added: def _p_resolveConflict(self, old, saved, new): print 'old:', old print 'saved:', saved print 'new:', new return new to SP.py into procedure class (DA.Procedure extends this), I've started Zope with runzope and there are no 'old':?, 'new':?, 'saved:?' statements at all on the console although other print statements from SP.Procedure are visible. Maybe these conflict errors I'm dealing with are different kind and are not falling into the correct piece of code or maybe this kind of test (print 'something') is too stupid to see if _p_resolveConflict is executed? -- Maciej Wisniowski ___ 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 )

[Zope] Re: MVC Approach
Thomas Adams wrote: Hi all, I'm a newbie to Zope, using version 2.7.3 (okay it is not the newest one) and I want to know if there is something like a MVC approach available for Zope, i.e. Model-View-Controller approach, as it is for instance in Java with the Struts framework from Apache. ... P.S: I don't know Zope 3 (Is that apossible answer of my questions?) Yes, Zope 3 has a MVC-like architecture. We call it the Component Architecture. It lets you separate responsibilities into different components (objects), e.g. content objects (they can be persistent, for example, or come from an RDBMS), views (e.g. browser views that produce HTML), adapters (enhance components with functionality), and utilities. For a structured introduction, see http://dev.zope.org/Zope3/ProgrammerTutorial or http://worldcookery.com. It is also possible to use Zope 3 style components in Zope 2 already, by using the Five product: http://codespeak.net/z3/five/. However, if you don't have any Zope 2 legacy, I can only recommend you start with Zope 3 from the beginning.

[Zope] Pluggable Brains
Hi Zope, I've been using pluggable brains in some zSQL classes. I have some questions! a) It seems if I initialize a variable in the __init__ method that variable, say self.callCount = 1 is not retained across calls, eg #python mod res = context.sql.brainySQL() for rec in res: rec.getCallCount() # where getCallCount is a method inside the Brains class and it just returns the var defined in __init__. But I get an attribute error instead. b) Can anyone direct me to a good faq on using these things? c) Has anyone experience with Pluggable Brains and zSQL? I am especially interest in performance issues because I intend to use Pluggable Brains to do *alot* of calculations - but only if the upside beats the downside of using them. d) Will Zope 3 support Pluggable Brains?
