(Yes, I used the contraction > properly too!). <g> I know (even before I read Michel's and Tim's messages), that I've mistakenly used the term open source in my argument. Perhaps I was thinking of the fishbowl process DC has put into place to allow a more open development process and public participation in decisions in general. Sorry for the misuse in this case. I certainly prefer an excellent open source product with bad naming conventions over a closed source product with good ones. I suppose I am most interested in consistent, representative naming. With Michel's explanation of the Python "Method" and generic script, I'm more comfortable with the name. I am, however, interested in what will be done to make ther other "Methods" less intimidating to new users as Michel argued was one reason for using Script. Will we end up with DTML Documents and DTML Scripts, SQL Scripts, etc.? Thank you, DC and Zope community, for a great product. I would use it even if they were called "little bits of Python code." :-) --- Ron

Re: [Zope] ZopeBook - URL to SQL

It it arrives at the URL's end, it checks whether the reached object is callable (this is the case for all kinds of methods and documents). If it is, the object is called. If it is not, ZPublisher checks, whether the object has (or can acquire) a method "index_html" (this usually is the case). It then calls this method. In your case: ZPublisher will reach the result object (as the Zope book describes). Unless you have wrapped this object into a custom class (aka brain, see "Advanced" tab), this is a "Record" object. A "Record" object is not callable. "index_html" is looked for, found in a folder above and rendered. That's what you see. What can you do? Wrap you results into a custom brain that either defines a "__call__" (that would need to be a Python defined class) or an "index_html" (this may be a non-persistent ZClass). Dieter

Ok. A disk quota of particular person? or folder? or some object? or is Zope itself not fitting in a disk quota? If you can't give us a brief example or more helpful description than this, you arent going to get much help. ----- Original Message ----- From: "Stephan Göldi" <web(a)goeldi.com> To: "Andy McKay" <andym(a)ActiveState.com> Sent: Friday, November 24, 2000 1:38 PM Subject: Re: [Zope] Quota in Zope > > A quota of what where? > > Disk quota >

When I 'jumped in' (nod to Chris Withers :-)) with my promotion of ZMethod, I'd missed Evan's announcement that he'd decided on Python Script - I thought it was just another suggestion and we were still in the middle of campaigning for the upcoming second poll! I'm actually not that averse to Script; it was ZMethod's OO associations that I liked - but if Michel thinks that such an association is actually not appropriate in this situation, then I'll bow to his greater Zope understanding. I agree with him that the new name needs to make it into the book, and Script is a reasonable choice. Is it intended to rename DTML Method, ZSQL Method, etc to be DTML Script, SQL Script, etc? For the sake of consistency I'm hoping so, and I think it's important that these revisions also make it into the book. Onwards!

Re: [Zope] images last-modified bug?

Júlio Dinis Silva writes: > I read sometime ago of a bug in zope not sending images header > last-modified, which cause browsers to always get images from > zope not using the browser's cache.... This only affects "App.ImageFile" objects. These are image objects that are in the filesystem and not in the ZODB. Usually, they are only used in Zope's management interface, although special applications may use them too. However, most images in Zope are "OFS.Image" objects that do send "Last-Modified" headers. In Zope 2.2.4 (to be released soon), the problem is fixed. The "b1" version has fixed it, too, but a small bug slipped in causing some images to be broken. Today, I saw a patch in the mailing list.

BSD 4 installation
by Lee Hunter 24 Nov '00

24 Nov '00

I'm trying to build Zope on a BSD server. According to the install.txt I have to run two commands - "python w_pcgi.py" and "./start". I managed to get the first command to run (python w_pcgi.py) after editing my Makefile.pre.in and do.py as per the FAQ.txt. But when I when I run the second command (./start) I get the following error message: media2: {38} % ./start Traceback (innermost last): File "/magma/users/u21/wake/zope/z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "/magma/users/u21/wake/zope/lib/python/Zope/__init__.py", line 94, in ? import ZODB, ZODB.ZApplication, imp File "/magma/users/u21/wake/zope/lib/python/ZODB/__init__.py", line 85, in ? import sys, ExtensionClass, TimeStamp, cPersistence, Persistence ImportError: No module named ExtensionClass Any ideas as to what I'm doing wrong?

It might well be, that the signal SIGHUP (hangup) is not implemented, at least that Python does not expect it to be always there. Dieter

Re: [Zope] Medusa Monitor

Anderson Ami writes: > Anybody knows What is Medusa Monitor ? What it do ? How can I use it ? The Medusa monitor allows you to connect to a running Zope Server and get a Python interpreter in this context. With it, you can (in principle) analyse your Zope system. However, this way of debugging is probably only for experts. There is a document at zope.org (I forgot its name) that says a bit about this "monitor": search for "monitor". Dieter
