Zope 2.3.3 back-downgrade
by Dario Lopez-Kästen 14 Feb '02

14 Feb '02

Hi! If I use PythonScripts, are there any serious problems with downgrading a Zope-2.4.3/2.4.4 to 2.3.3? I cant remember if 2.3.3 had pythonscripts, but i recall that there was a product that later became officially pythonscripts... Are there any other incomaptibilities that anyone knows about? Thanks. /dario - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario(a)ita.chalmers.se ICQ will yield no hits IT Systems & Services

Request for IPC10 and Zope 3 Sprint Pictures
by Casey Duncan 13 Feb '02

13 Feb '02

Oh, ye mailing list gods, forgive the cross-post... I am making a photo album that will be featured in the next issue of the Zope news. I took several snap-shots at the Python conference and the Zope 3 Sprints, but I'm sure I missed a lot. If anyone cares to contribute some snapshots they took to the photo album, please send them to me! Just email the jpegs (any size, I will crop) to me and if possible a caption or a list of the people in the picture (I don't know everybody 8^). And please make sure the pictures are suitable for "family viewing" 8^). I will of course give each photographer credit in the album. Thanks a bunch! P.S. The Zope news will be coming out pretty shortly, but I will continue to add pictures to the album as I get them. /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association c.duncan(a)nlada.org \---------------------------------------------------/

putting dtml-methods under CVS ?
by Romain Slootmaekers 11 Feb '02

11 Feb '02

Yo, Our team is working on a Zope-product. Each developer has it's own zope server, and the python code for the product is maintained under CVS. the problem we have is that the some of the dtml-methods are written with the Zope management interface and end up in the ZODB. We want to put them under CVS control as well. Now I've been looking at some options: -) CMF's File System Directory view (appearantly only for lib/python/Products/CMF* stuff) -) CMF's FSDTMLMethod (but that one isn't modifiable through the management interface. -) FTP as a way of uploading the files to the ZODB I'm sure someone else must have faced this problem before... Input appreciated, Sloot.

Re: [Zope-dev] ZMI textareas on Windows IE6 are '100%+' wide, cause scrolling inconvenience
by Jeff Kowalczyk 09 Feb '02

09 Feb '02

[Jeff] You're right, I wonder if this is a documented change in IE6, or a bug they plan to fix? I can't imagine in what universe that including the scrollbar-obscured area in the 100% width makes sense. I'd hate to see all browsers' HTML get munged to cover this bug up. But given the pervasiveness of IE6, maybe the ZMI should make some accomodation for a preference that 9x%'s the width of the right frame. [Joachim] I think the problem is more severe. IE 6 has obviously changed behaviour compared to IE 5.5. I'd call it a bug. It now always calculates "100%" with the right-hand bar's width INCLUDED, so there are other side-effects than the one you are describing, like the last tab on the right being partially covered by the scroll bar. So if we change the HTML, it should limit the width of the WHOLE right-hand frame, not just the textarea's width ... Unfortunately this will only work automatically with some browser detection ...

ZMI textareas on Windows IE6 are '100%+' wide, cause scrolling inconvenience
by Jeff Kowalczyk 09 Feb '02

09 Feb '02

On my Zope 2.5.0 running on WindowsXP/IE6, the ZMI's textarea boxes, for things like editing PageTemplates, becomes too wide for the frame when the vertical scrollbar is required, causing an inconvenient side-scrolling behavior. The frame must be scrolled sideways to view the text areas's scrollbars, which then obsures the far left of the textarea. This is the code in question (for a PT edit page, there are many others) Expand macros when editing </td> </tr> <tr> <td align="left" valign="top" colspan="4"> <div style="width: 100%;"> <textarea name="text:text" wrap="off" style="width: 100%;" cols="40" rows="15"><html metal:define-macro="page"> Would it not help to make the textarea and div width 90% or so to account for the potential width of the side-scroll bar on the right-hand ZMI frame? Or even better, this could become a preference setting, since some users will have very narrow scrollbars or extreme vertical resolutions. After all, there is a cols/rows insertion right next to it, perhaps a new preference setting is easy enough to add...

RELEASED - StandaloneZODB 1.0 final
by barry＠zope.com 09 Feb '02

09 Feb '02

I'm please to announce the release of StandaloneZODB, the Python object persistency system also known as the Z Object Database. ZODB is the object-oriented database underlying Zope; the StandaloneZODB project's goal is to provide those same facilities to non-Zope related Python applications. Today we are releasing StandaloneZODB 1.0 final. A brief description of the changes since release candidate 1 is outlined below. StandaloneZODB is based on the same code as the ZODB in Zope, albeit on a separate release branch. Its inspiration comes from Andrew Kuchling's StandaloneZODB project on SourceForge. While there are still some differences, the Standalone 1.0 release is the first on the path toward convergence. Subsequent releases should complete the merge of Andrew's and Zope Corporation's packages. The StandaloneZODB release includes the following components: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO - Experimental Berkeley storages - Some documentation <wink> See the README file for details on building and installing StandaloneZODB. For details on using ZODB, see Andrew's included user guide. StandaloneZODB 1.0 is released under the ZPL 2.0. It should be compatible with all Python versions from Python 2.1 to Python 2.2. It may or may not work with versions earlier than Python 2.1. Download StandaloneZODB-1.0 from: http://www.zope.org/Products/StandaloneZODB and visit the StandaloneZODB Wiki page at: http://www.zope.org/Wikis/ZODB/StandaloneZODB See also: http://www.zope.org/Wikis/ZODB/FrontPage for more information about our long-range ZODB plans. Enjoy, -Barry Barry A. Warsaw Zope Corporation, Pythonlabs barry(a)zope.com -------------------- snip snip -------------------- What's new in StandaloneZODB 1.0 final? Release date: 08-Feb-2002 ======================================= All copyright notices have been updated to reflect the fact that the ZPL 2.0 covers this release. Added a cleanroom PersistentList.py implementation, which multiply inherits from UserDict and Persistent. Some improvements in setup.py and test.py for sites that don't have the Berkeley libraries installed. A new program, zeoup.py was added which simply verifies that a ZEO server is reachable. Also, a new program zeopack.py was added which connects to a ZEO server and packs it.

Module changes not taking in external method
by Ted Skolnick 08 Feb '02

08 Feb '02

Hi I am a zope newbie getting started by using external methods. I am importing modules from another package in my external methods and having some problems. When I change code in the external method, I see thos changes take right away when I call the method from the browser. But when I change code in the imported modules, I don't see the changes take until I reboot zope. Is zope cacheing my modules? Any thoughts? thanks, Ted

Benchmarks: DTML vs. ZPT?
by Joachim Werner 08 Feb '02

08 Feb '02

Hello! Has anyone done any performance comparisons between DTML and ZPT yet? The reason I'm asking is that we did some first(completely unscientific) tests and had the impression that ZPT were actually quite a bit SLOWER than DTML - and I just can't believe that ... Joachim
