[Zope-dev] 2.9 goals
I'd like to propose/sponsor/promise-to-finish the following for inclusion in 2.9. If anyone has fears/doubts/problems with specific things, please let me know. I can also start a 2.9 project on the wiki with this info; if other folks have features they want, maybe they can post them here and we can put together a release plan. Definitely: - Chris Theune's blob support for ZODB (currently on the ctheune-blobsupport branch in ZODB's SVN repo) - Speed up large PUTs: http://mail.zope.org/pipermail/zope-dev/2005-April/024617.html - Implement RESPONSE.isClientConnected() to be able to tell if the client that made the request is still connected (allow long-running app code the possibility to abort processing if it notices the client is not connected). Maybe: - Include ClockServer: http://plope.com/software/ClockServer - ZODB connection policies, which will allow you to associate a thread pool with a particular set of ZServer servers. This will allow sites which are having resource exhaustion problems (e.g. running out of threads, running out of database connections) to continue to be accessible via servers running on special ports for debugging and maintenance purposes. It should also allow site admins to associate a particular thread pool with connections from spiders and other cache-busters by associating particular user agents or other request parameters with a thread pool. Work towards this was done on the chrism-zserver-connection-policies-branch branch in CVS a while back.

It makes a lot more sense to pick something that can be used both now and into the future than hack something together. If someone wants to create a way to manage product-specific configurations in a single file, it's not hard to create a Python package to support that, and products that want to have their configuration placed in that file could set themselves up to use %import in that file.

Re: [Zope] Problem with ZSQLMethods/MySQL after update
Thanks a lot for your help, Dieter, Greg, and Andy! Dieter, you were absolutely right about the broken instances. All I had to do was delete ZSQLMethods from my Products folder and restart Zope. Everything was all right after that. Andy and Greg, so far I did not have any problems using mysqlpython 1.2.0 with ZMySQLDA 2.0.8. But since Andy is the expert I now installed 2.0.9b3 and am happy with it. :-) Cheers and thanks again, Ragnar On Tue, 28 Jun 2005 19:43:15 +0200 Dieter Maurer [EMAIL PROTECTED] wrote: Ragnar Beer wrote at 2005-6-27 18:50 +0200: After upgrading Zope from version 2.6.4 to 2.8.0 and mysqlpython from 0.9.2 to 1.2.0 I cannot add or edit ZSQLMethods anymore, although there is an open(MySQL)db-Connection that works just fine with the same ZSQLMethods that cannot be edited or with external methods.

[Zope] Re: TAL and Javascript
Rob,
I was recently working on a similar problem.
You will need to use the xmlhttprequest function in _javascript_ do
all the work. And its quite easy once you get the hang of it. Heres a
good tutorial to get started:
http://developer.apple.com/internet/webcontent/xmlhttpreq.html
For your problem, if your required server result is a simple list, let
a zope script generate a tab-delimited list and you can retrive it
using the request.responseText (see the xmlhttprequest) and skip
working with the XMLDOM, which can by quite annoying.

Thanks to all the responders. It gave me some ideas, but alas no luck.
To clarify, I am not trying to do everything in one request. Request
one generates the page, a user event (selecting an option from a form)
fires another request via _javascript_.
like:
script tal:content=python:'function getFormats() {
var widget = document.getElementById('orgs');
var chosen_org = widget.options[widget.selectedIndex].value;
var formats = %s;
// build selection 2 options from formats
' % here.getDataFormats(chosen_org) /
And then a user event (onChange) calls getFormats.
Even with generating the script with a Python script or DTML, the
problem remains (for me at least) to get a value from the DOM passed as
an argument to a Python script that queries my database. If my Python
script didn't take an argument, I'd have no problem. I could do this
and use _javascript_ to build the select options from the appropriate
values. But I'd like to cut down on what the browser has to handle.
What the user chooses in the first selection can reduce what they get
to choose in selection two from 3000 choices to hundreds. I'd prefer to
have the backend reduce the result set rather than having the browser
do the work.
I thought about AJAX (no experience), but given time constraints, looks
like I'll have to load everything on the page and go from there.

Re: [Zope] Newbie Questions - many-many relationships? Zope 2 or 3?
Hello again, So, following the recommendations from the board I have settled on route 3 - developing a Python Product, using Zope 3. I've been refering a lot to the Zope 3 Book (particularly chapter 13 onwards) and have progressed somewhat. I've created a PropertyFolder class, which can hold Property obects, and following the example in the book I've been able to make it hold *only* Property objects. My Property class is proving a little more difficult, however. When I've tried to make it along the same lines as the message class in the book, I run into difficulties - it seems to be some sort of problem with inheriting from multiple classes / interfaces. My workaround has been that I can include my __setitem__.precondition within the main IProperty interface, and make that subclass from IContainer instead of Interface. This works for me, because I'm not going to want Property objects to contain other Property objects, but I really haven't been able to track down why it should work for the message board, but not for my classes / interfaces. The errors I was getting before my work around seemed to be indicating that it wasn't a container, although I was subclassing BTreeContainer, and implementing three interfaces (one and Interface, one and IContained, and one IContainer). Mostly this presented itself as Zope complaining about using __len__ on the object. (As I say, I have worked around this, and mention it mostly in case it sheds any light on the issue below...) My current problem, however, is proving harder to work around. I want my Property objects to be able to contain Images, and sets of attributes. (A typical set of attributes would describe what is in the kitchen). I have created interfaces IAttribSet(Interface), IAttribSetContainer(IContainer) and IAttribSetKitchen(IAttribSet); and classes AttribSet (implements IAttribSet and IAttribSetContained) and AttribSetKitchen (implements IAttribSetKitchen). I am using IAttribSetContained to create a __parent__ ContainerTypesConstraint. I have wired up the kitchen attrib set in .zcml files. When I 'turn off' implementing IAttribSetContained, my kitchen attrib set is working fine, in that I can add it anywhere, and edit it. However, when I try to add a condition saying where it can go (i.e. I only want it to be within Property objects) it correctly only appears as an Add-menu item within Property objects, but on adding it, I get an error, saying AttribSetKitchen instance has no attribute '__parent__'. My Property and PropertyFolder objects are implemented as BTreeContainers. I'm really quite stumped by this, so I would appreciate any guidance that could be provided on tracking down the source of the errors.

If I want to add extra feature to my product on the development server and then port them to the live server (with all the data on the live server being left in tact), will selection of either of these particularly help or hinder me in this? I don't know, because when I tried 2., it turned out to be quite complicated, and I never understood how to do it. So I did 3. And afterwards I have realized that even if you do understand how to do 2, the fact that you do most of your stuff in the restricted python scripts and dtml or ZPT, means that you have tons of limitations to go around. In addition to that, you can't easily use any proper editors to edit the code, which is very annoying. Method 2 (aka ZClasses) simply seem to offer exactly zero benefits, and loads of drawbacks.
