(One of the last things i did at my prior job, at CNRI, was to resurrect and revitalize the prototype Mailman, for use as the maillist manager on python.org.) I moved on to other things, and the MMRoster product may be way out of date - i don't even know if the mailman interfaces have changed from underneath, and i *know* that the zope ones have - but the product still may offer some useful clues about one way to hook up with mailman. I just uploaded a tarball of it to my members folder - see http://www.zope.org/Members/klm/MailmanStuff/MMRoster.tar.gz (I know ethan is interested in this topic, and barry warsaw, mailman's current maintainer and my old colleague/buddy, has also expressed interest, so i'm cc'ing them.) All this said, i'm spread too thin at the moment to be able to *do* much more than watch, maybe chime in, if stuff happens... Ken Manheimer klm(a)digicool.com

Problems with pcgi_wrapper.exe
by Jay, Dylan 01 Jun '00

01 Jun '00

I am running Zope as a service under WinNT workstation. I am running it behind "Personal Web Server". Problem is that pcgi_wrapper.exe seems to hang. If I access a page with a large graphic on it I might get the page but the graphic will not come but it will still try loading it. Anyone had a similar problem?

Z Search creates input fields with "width=30"?
by Jason Byron 01 Jun '00

01 Jun '00

Shouldn't the input fields created with Z Search include "size=30" instead of "width=30"? I'm using an older version of Zope so maybe this has been changed already? __________________________________________________ Do You Yahoo!? Send instant messages & get email alerts with Yahoo!

[announce] MountedFileStorage product - mount multiple ZODBs.
by Anthony Baxter 01 Jun '00

01 Jun '00

I've bolted together a simple Product which allows you to mount sub-ZODB's through the zope management interface. http://www.zope.org/Members/anthony/software/MountedFileStorage/ (it's now up to version 0.01 :) It _requires_ an up-to-date CVS version of Zope. It won't work on 2.2a1. I'd expect it will work on 2.2, whenever that happens. Most of the credit for this goes to the guys at DC who did all the work - but any bugs are probably in my bit, not the bits they did. Anthony readme follows: Created by anthony. Last modified on 2000/06/01. Ok, so the DC guys have been talking about allowing multiple ZODB support, but I couldn't see a way to use it. A bit of trawling through the CVS and I found the guts of a MountedItem object which has now been removed. Using that as inspiration and a source of pointers, I've bolted together a really simple Product for mounting multiple ZODB files onto a Zope installation. You should also check out the MountedDatabases section of the ZODB Wiki. First of all, you need to be running a really really recent CVS version of Zope. 2.2alpha1 isn't good enough. Then install this product (it unpacks in lib/python/Products/MountedFileStorage). Sample usage: cd $zope/var ; cp Data.fs.in nifty.fs Select Mounted FileStorage from the product add list. For file put nifty.fs. Leave path blank, and put whee as the id. You've now got a copy of the default Zope install mounted. In the same session, add a new Mounted FileStorage, for the Path put in QuickStart/Outline. Leave id blank. You've now mounted the QuickStart/Outline folder from the mounted FS as Outline in the current folder. WARNING: This is really really untested stuff. It Works For Me. Not To Be Taken Internally. Do Not Come Crying To Me If It Breaks Your Zope Install. If you want to play with this stuff, you really should back up your Data.fs first. Security Issues: There probably are some. I've no idea what they might be. The product makes a really simple-minded effort to not allow badness through (any filename with a / or \ in it). Don't give access to the permission Mount FileStorages to anyone that you don't trust, though. Note that this includes anyone with Manager role on the system. Note also, though that you can only mount existing files that are in var/.

Linking to Mailing List Managers
by Ian Sparks 01 Jun '00

01 Jun '00

Hi, With all the talk about Syndication I started to think about linking with mailing list managers. Ideally I'd like members of my portal site to be given a free email address <username>@<sitename>, bouncing all mail to that address to their real email address. In a roles-based membership scheme it would also be nice to be able to send email to <role>@<sitename>, so the email goes to all members with that role. Has anyone done anything like this, linking to an existing Mailing List Manager like Majordomo from Zope? I want to manage the whole thing through some Zope management pages. - Ian Sparks.

ZopeDA Event Notification, was: Interbase / Cacheing
by Jerry Spicklemire 01 Jun '00

Regarding the implementation of custom functionality in PostgreSQL, here's an "overview" from the PostgreSQL Programmer's Guide: "How Extensibility Works Postgres is extensible because its operation is catalog-driven. If you are familiar with standard relational systems, you know that they store information about databases, tables, columns, etc., in what are commonly known as system catalogs. (Some systems call this the data dictionary). The catalogs appear to the user as classes, like any other, but the DBMS stores its internal bookkeeping in them. One key difference between Postgres and standard relational systems is that Postgres stores much more information in its catalogs -- not only information about tables and columns, but also information about its types, functions, access methods, and so on. These classes can be modified by the user, and since Postgres bases its internal operation on these classes, this means that Postgres can be extended by users. By comparison, conventional database systems can only be extended by changing hardcoded procedures within the DBMS or by loading modules specially-written by the DBMS vendor. Postgres is also unlike most other data managers in that the server can incorporate user-written code into itself through dynamic loading. That is, the user can specify an object code file (e.g., a compiled .o file or shared library) that implements a new type or function and Postgres will load it as required. Code written in SQL are even more trivial to add to the server. This ability to modify its operation "on the fly" makes Postgres uniquely suited for rapid prototyping of new applications and storage structures." That last sentence tells much of the story. PostgreSQL was originally developed as a test bed for experiments in manipulating both tabular and non-tabular data. As such, significant effort has been devoted to providing an extensible toolkit, to meet the requirements of discoveries arising from an experimental environment. In PostgreSQL, the limit to flexibility seems to lie more with the user than the system! Later, Jerry S.

RE: [Zope] Form POST question (and a QUERY_STRING Q.)

Hi, There was a thread a week or so ago about passing POSTed variables after authenticating, some of which will be useful -- see the archived message, suggestions and caveats at: http://zope.nipltd.com/public/lists/zope-archive.nsf/47ba74c812dbc5dd8025687 f0024bb5f/3e46f2835c820eae802568eb002c802a?OpenDocument Regarding your second question, REQUEST.QUERY_STRING works for me using Zope; maybe someone else has some pointers regarding its use in "the old bobo fashion" with which I'm not too familiar. hth, -- Marcus > -----Original Message----- > From: Yosef Gold [mailto:yosef@adsc.com] > Sent: 01 June 2000 12:50 > To: zope(a)zope.org > Subject: [Zope] Form POST question (and a QUERY_STRING Q.) > > > I use Zope in the old bobo fashion.
