catalogObject changes (Zope-2_6-branch)
by Yuppie 08 Oct '03

08 Oct '03

Hi! Yesterday I spent some hours tracking down why catalog Metadata and catalog Indexes are getting out of sync in my CMF Site. I found that checkin <http://cvs.zope.org/Zope/lib/python/Products/ZCatalog/Catalog.py.diff?r1=1.…> including this new condition <code> if not idxs: # if the caller specifies that we should update only a # specific set of indexes, we don't do a metadata update. self.updateMetadata(object, uid) </code> Could anybody tell me what's the rationale behind that checkin? - it breaks backwards compatibility - it's only in Zope-2_6-branch, not in Zope-2_7-branch or HEAD - I can't see what this 'if' is good for anyway Cheers, Yuppie

Re: Which version of ZODB and ZEO to use for Zope?
by Dario Lopez-Kästen 08 Oct '03

08 Oct '03

Hi again, and thanks for all the replies. Given that we are going to use this to deploy to production within the coming week, we will stick with Python 2.1.3, Zope 2.6.2 and use ZODB 3.1.4. We will wait for Zope 2.7 to stabilise or reach a 2.7.x version before we switch tp Python 2.3.x and ZODB 3.2. Thank you again for all the responses. /dario - -------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

Risks with Zope 2.6.2 with Python 2.2.3
by Dario Lopez-Kästen 08 Oct '03

08 Oct '03

Hello, following Jeremy Hylton's advice, I would like to ask the developer community: what risks are associated with Zope 2.6.2 with Pythoin 2.2.3? Thank you, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

Re: [Zope-dev] Risks with Zope 2.6.2 with Python 2.2.3
by Eric Brun 08 Oct '03

08 Oct '03

Hello, I try to run Zope2.6.2 and ZODB3.2 with python 2.2.3 but it failed. Then I modified a few ZODB3.2 (remove 'object' inherite on some classes like Connection.py DB.py and some others). I have succed to run ZEO and Zope 2.6.2 on python 2.1.3. Perhaps is not so well, but it's run. Is there any risks to do that too ?

Hello, the subject says it all. I have looked at the ZODB site, but I can't find any conclusive info. Thanks, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

Re: CVS File 0.9 bugs
by Craeg K Strong 07 Oct '03

07 Oct '03

Thanks for your note. Yes, version 0.9 went out with some silly bugs, and I haven't had time to fix them. However, we now have a customer funding some Zope-related work, so I imagine I will have time to work on CVSFile again within 3-6 weeks. CVSFile will be supported until it gets replaced by another Zope add-on that will add CVS functionality to the Adaptable Persistence Engine (APE). We will be looking into that for our customer as well. APE is the wave of the future, it will ultimately replace ExternalFile (the current underpinnings of CVSFile), ExtFile, LocalFS, and lots of other related products. As far as migrating from a Zope site developed the traditional way, you have to decide what is worth versioning and what is not. For example, in what format is your content? Is it in XML? HTML? Is it mixed in with your formatting directives inside your ZPTs? Or perhaps is it all in DTML documents? We used versioning for anything meeting any of the following criteria - multiple developers might work on it simultaneously - content that needs to be reused - anything changing rapidly that might need to be reverted or needs an audit trail Under that definition, quite a few zope objects should be versioned, all but the most trivial ones, really. One option is to have a folder full of versioned CVSFiles in a tree, parallel to your "real" site. Your "real" site then merely navigates in via aquisition and retrieves its content from objects within the versioned area. That way, you have *two* hierarchies. One is for the site. One matches the file system and CVS. I found this arrangement a little easier to handle, because I could refresh the entire CVSFile hierarchy in a batch and watch my website update :-) See the latest CVSFile batch oriented functionality for more details. Hope this helps, --Craeg PS, I cc'd the zope-dev mailing list, as I feel the conversation might be helpful to others...

Unicode encoding/decoding
by Bjorn Stabell 07 Oct '03

07 Oct '03

How does Zope handle Unicode encoding/decoding of non-UTF8 encodings? I see encoding/decoding functions popping up in products (e.g., Archetypes), but I thought Zope already had this covered? Bye, -- Bjorn

Using 2.3.2 for Zope 2.7
by Chris McDonough 06 Oct '03

06 Oct '03

Some people at ZC have made pretty compelling arguments to make Python 2.3.2 the "recommended" version of Python to use with Zope 2.7 final. I'm wondering if other people have a strong feeling about this either way. -- Chris McDonough <chrism(a)zope.com> Zope Corporation

Javascript variables Form element values and zope
by Gavin Park 06 Oct '03

06 Oct '03

Thanks to Dieter and jcc, I didn't think there was going to be a sneaky way to mix zope scritps and javascript in a live page, but hoped there may have been some neat trick ... Looks like its plan B - submitting the form from one frame to another and using the request doohicky. Gavin
