Proposed solution for ZODB woes
by Lalo Martins 21 Feb '00

21 Feb '00

Right now we have a provision for non-persistent variables (with _v_, which I assume is for ``volatile''). The obvious way to fix the incontrolable growth of ZODBs is creating a new prefix for ``non-undoable'' variables, perhaps _t_. Implementation-wise, these variables would be stored in a different area. For filesystem storage, the best implementation is probably using a second file for all _t_ stuff. (Actually, they can be kept in RAM and only synced to this file periodically). The other part is giving Zope objects a way to have _t_ and perhaps even _v_ properties.

Using 'AND' and Keyword indexes
by Jason Spisak 20 Feb '00

20 Feb '00

Zopists, Does anyone know the way to get AND functionality to work with Keyword indexes? If I pass the index ['foo', 'bar'], it brings up anything with 'foo', and anything with 'bar'. I;d like to get bak anything that has both 'foo' AND 'bar'. Anyone done this yet? -- Jason Spisak 444(a)hiretechs.com

Subclassing ExtensionClasses in C?
by James Henstridge 20 Feb '00

20 Feb '00

This question is not directly related to zope, but I was told on comp.lang.python that this would be a better place to ask. The question is about the ExtensionClass package that now seems to be maintained as part of zope. I guess the problem might be encountered by some people writing zope packages, so it is sort of zope related :) I am looking at converting my pygtk wrapper for GTK+ over to using ExtensionClass (because it will reduce the amount of code needed, and make it easier to autogenerate the wrapper, among other reasons). This would involve creating a fairly deep heirachy of classes defined in C. While looking through the ExtensionClass documentation, there were examples of creating ExtensionClasses and subclassing extension classes from python, but no examples of subclassing from C. Is this actually possible to do with ExtensionClass? I noticed it is possible to create a PyMethodChain for each class, which would allow inheritance of methods, but does not handle `instance of' type relationships, which I need to do some type checking. I hope someone knows the answer to this. Thanks, James Henstridge. -- Email: james(a)daa.com.au WWW: http://www.daa.com.au/~james/

Zope Usage
by Sin Hang Kin 20 Feb '00

20 Feb '00

Reading the source code of zope, I find out the current code contains many contstants: BGCOLOR lang CELLSPACING ALING I would like to suggest zope default to a stylesheet oriented setting with these constants defined as attributes in root folder. This will give the later developer greater flexibility to modify the zope management interface. The constant lang=en is however not very apropriate when developing multi-langual applications.

MailHost need to be modified?

Hi,all When I used MailHost to serve my project to send mail, It cannot work properly. I have to press two ENTER in the comments fields. Otherwise the message that user input cannot appeare in the body of the Email. I think that this fault should be correct to fit the use. Thanks a lot! Victor zhai.

https://zope/manage

zopistas, I'm starting up that web hosting company I nattered on about a bit ago, and I was wondering what I should do to get the manage* working properly with SSL: i.e., how do I control what zope prepends to BASE (http, https, ftp)? I really want to let my clients have secure access to their files. Thanks, ethan

TIP: Must enable 'new' for FreeBSD Python 1.5.2 port to install PythonMethods
by Tom Neff 19 Feb '00

19 Feb '00

I thought I would pass this on to the assembled geniuses since I just found it out. FreeBSD 3.3 stable, running Zope for a while, Python 1.5.2 built long ago, everything working fine. Decided to install the PythonMethods product -- it comes up broken. The error came in zbytecodehacks/opbases.py, line 1: import struct,dis,new because there was no module 'new'. It turns out that in the FreeBSD port of Python 1.5.2 (/usr/ports/lang/python), the Modules/Setup file is substituted with one that turns off Tommy Burnette's 'newmodule'. I have no idea why this should be, or why they didn't make whatever changes they needed as a Patch rather than an absolute overwrite of the file, but however it happened, you need to turn it back on in Modules/Setup and then remake and reinstall. Once I did that, PythonMethods comes up fine and other products (like BannerFolder-0.3) that rely on it, install as well.

Problem with new Banner System (and workaround

Umm ... seem to have generated an issue with Renderable in the first traceback.

Re: [Zope-dev] current CVS product importing broken?

Further to my own email: A freshly checked out Zope2 CVS does not have this problem - so it's obviously something bogus that I've done locally. Yay. More when I figure it out.

current CVS product importing broken?
by Anthony Baxter 19 Feb '00

19 Feb '00

I'm running current-CVS, and I'm finding that no matter what I do, no new products will be imported, and that if I delete the entries from Control_Panel/Products (say, MailHost), and restart, it's still gone. I'm digging into the code right now, but I'm really confused - can someone else out there confirm this, or is it just me? ta, Anthony
