XML-RPC incorrect 404 return code
by Alan Milligan 07 May '04

07 May '04

Hi, I'm doing some stuff using Zope as an XML-RPC server, and have come across a rather interesting bug. If the method doesn't exist on the Zope server, Zope returns an xmlrpclib.Fault with a faultCode= -1. This completely trips out my XML-RPC client which was rather expecting an xmlrpclib.ProtocolError. Does anybody have a strong opinion on sorting out ZPublisher.xmlrpc.py to to do a little more than it's present rather lame error handling?? Alan

Change in repository approach to software sharing
by Jim Fulton 07 May '04

07 May '04

The Zope project includes a number of interrelated subprojects, such as: - Zope 2 - Zope 3 - ZODB - ZConfig Software from the ZODB and ZConfig projects are shared by Zope 2 and Zope 3. We want this sharing to be very convenient for people working on Zope 2 and Zope 3. We don't want users of the Zope 2 and Zope 3 repository to have to do separate checkouts for ZODB and ZConfig. CVS supports such software sharing through it's "module" system. The module system has some flaws, so we use symbolic links instead. In a response to: http://dev.zope.org/Zope3/MovingSCMToSubversion John Belmonte has suggested that Zope 2 and Zope 3 should depend on specific versions of shared packages, rather than on the head. I'm inclined to agree. People working on ZODB and ZConfig have to test their changes against both Zope 2 and Zope 3 to avoid breakage. This is very burdensome and causes much pain when they get it wrong. Fortunately, subversion provides a mechanism for sharing specific revisions. We'll be able to have the convenience of getting ZODB and ZConfig (and other shared software) when we do a checkout *and* we'll be able to control what parts we get. To see how this will work, we'll look at ZConfig as an example (because it has a single package) of reusable software that we will include in Zope 3. In the repository, we'll have a top-level Zope3 project directory, with the standard svn subdirectories "trunk", "branches", and "tags". We'll also have a top-level ZConfig project directory. The "trunk" of the ZConfig Python package will be in ZConfig/trunk/src/ZConfig. If we create a tag T1 of ZConfig, then the Python package for that tag will be in ZConfig/tags/T1/src/ZConfig. Now, when we set up the Zope 3 repository, we will create the ZConfig package in Zope 3 by copying a *tag* from the ZConfig project: svn copy svn+ssh://svn.zope.org/repos/ZConfig/tags/T1/src/ZConfig \ svn+ssh://svn.zope.org/repos/Zope3/trunk/src/ZConfig -m 'Bring ZConfig T1 into main branch' Then, whenever someone checks out the Z3 trunk, they'll get the ZConfig from T1. If we need to, we can even make Zope3-local changes to ZConfig. Later, we may decide to upgrade the Zope 3 head to use ZConfig tag 3. At that point, we can recopy from the tag, or we can merge changes made between the two tags. A similar technique can be used for external software, as described in: http://svnbook.red-bean.com/svnbook/ch07s04.html Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

Zope and ESI
by Ganesha Shanmuganathan 06 May '04

06 May '04

Hi all, Has anybody used ESI with zope ? I know that ESI support was added to squid and the project was funded by Zope corporation. But I could not find much information on the project after that. We are planing to experiment with ESI for one of our projects and if required implement a framework for zope (we will make it available to everyone if we implement it), which is similar to JESI, since manually embedding the tags could be a pain and moreover things like aquistion must be handled automatically by the framework. I would like to hear others experiences with ESI with zope. Also how the ESI tags were used and what were the performance benefits. Thanks, ganesh -------------------------- Ganesha Shanmuganathan ZeOmega --------------------------

RE: [Zope-dev] How should an ideal Zope IDE look like?
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 06 May '04

Well, I suspect the interest in this type of tool might be big enough to allow for the open Source model to apply in an efficient manner ? Depends on the skills required to bring it to life. I've started using Eclipse lately, and I just love it, I've combined PyDT/PyDEV + Subclipse + XMLBuddy and I have a decent tool for working on my products and skins. At home, I have a similar setup for working with Python/C, and it's fantastic, I'm far more productive with it. Some people might take offense to using a Java tool to do the job, but it seems to me like a potentially excellent foundation. Apparently Jython can be integrated into it ... I've been meaning to learn Java, maybe this would motivate me ? :P As for Zope IDE vs. CMS IDE ... The line (to me anyways) is blurry. Also, given current projects, I'd focus on Zope 3, which with it's component architecture makes things infinitely flexible, and therefore the line between Zope and "CMS" is not easily distinguishable. Ideally a full featured IDE would be component architecure aware and be able to discover and leverage it (Which interfaces do you have ? Which components ? How do I display this to the user ? Use that for code completion, Zope aware debugger somehow, etc ...) Maybe the ZMI functionality should be abstracted into a web service or something similar so that the ZMI is no longer purely restricted to a web interface? (Maybe it already isn't, admitedly, I don't know ...) Anyways, admitedly all this is above my skill level at this time, but I think the idea has value ... If this were a reasonably priced commercial tool, I probably would buy it mind you. Spending say a few hundred dollars to save hours and hours of work is common sense. though a tool like that would be years away even someone started now!

Sounds like the opportunity for a commercial tool. It's not NEEDED, but it makes life a LOT easier, and so would give any company with it competitive advantage without detracting at all from people who don't use it... > My main concern would be it's adaptibility to custom content types.

That's the tough one ;-) BTW, I thought we were talking about a Zope IDE, not an IDE for a CMS built on top of Zope... > Basically, yo me this should be a core feature of Zope, not an add-on. Indeed. But having it as a core feature forces it to be open source, and hence run on open source budgets and timescales. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

There's a svn property you can set on a higher level folder in the repository that can control a mapping for file extensions to this property, IIRC.
