[Zope3-dev] Zope and a RDB
Hello, JSR 170 http://www.cmswatch.com/Feature/123 http://www.artima.com/lejava/articles/contentrepository3.html seems to be the next standard of the CMS world. Wouldn't be a good thing to make Zope 3 compatible with this standard ?

[Zope3-dev] Google SoC Project
Hey everyone, Nate sent just a message that I am interested in a SoC project with the Plone Foundation. Okay, let me write something too. I think doing a SoC project would be a lot of fun and would give me some time to work on Zope 3. Unfortunately, I am a little bit lost to what I could do that widely benefits Zope 3, Zope 2, CMF and Plone. Here are some of my ideas, some are stolen from the Plone project suggestions: 1. Finish the ZSCP site[1] I think that the ZSCP process will be vital for controlling software quality in the future and provide people with a valuable resource for additional Zope software. My original proposal was modest by design, since I did not anticipate to have much time to work on a larger vision. With the SoC project I could finish the implementation of the proposal and extend the scope to be more inclusive of existing packages/products, especially with regard to Plone. This project would fit the SoC program well, since its scope is well-defined and extensible. .. [1] http://mail.zope.org/pipermail/zope3-dev/2006-February/018319.html 2. Implement Local Sites in ZCML I already mentioned this several times: It would be very nice, if we could define local sites in ZCML. I understand this task very well and could write a proposal and implement it in a well-defined time frame. BTW, this task is a must happen, if we want to port something like Plone to Zope 3 eventually. This project might be too short for the Google SoC. But I think it has a lot of potential. 3. Optimize ZCML We talked about it many times. The startup time for Zope 3 is too long. In part this is due to the schema field conversion and verification of the ZCML attributes. I would like to work with Jim on some strategies to optimize the startup time by reducing the ZCML processing. Over the years we have thought of several solutions, but they all involved a lot of hard labor that noone was willing to do for free. Well, getting paid to do it, is a good motivator. ;-) Of course, this is also very important to the Plone people as more and more ZCML is being used. I think that this project would have exactly the right timeframe and scope for a Google SoC project. 4. Implement a Query Framework and Language for Zope Through my contract work I have recently played extensively with catalogs and indices in Zope 3. Furthermore I have used hurry.query for all my searches. I think hurry,query could be extended to become a full-featured query framework for Zope, including ad-hoc searches of objects. Furthermore, over and over again we get requests from people wanting to quickly query the ZODB (or at least the content space). I think it would be possible to build a query language on top of hurry.query. This project would be somewhat experimental, but fit the spirit of Google's SoC. 5. Implement Portlets Implement portlets in the sense of JSR 168. I think that a Zope portlet implementation in the spirit of JSR 168 is very feasible and would benefit a wide variety of Zope users. Achieving full JSR 168 compatibility is probably a lot more tricky and a risky objective, since I do not know the entire standard. I think if the project would state that we try to implement portlets and only try to discover the feasibility of JSR 168 compliance, then this could be a decent S-C project. But I am not as thrilled about it, since it involves a standard. ;-) That's it! Let me know, if you can think of any tasks that would bring us all forward.

[Zope3-dev] Re: Google SoC Project
Hi Stephan! Nate sent just a message that I am interested in a SoC project with the Plone Foundation. Okay, let me write something too. It feels almost like cheating, since you're likely to know more than any potential mentor about the stuff you're working on, but I think it'd be a great idea to give you more time and compensation for contribution. ;-) I think doing a SoC project would be a lot of fun and would give me some time to work on Zope 3. Unfortunately, I am a little bit lost to what I could do that widely benefits Zope 3, Zope 2, CMF and Plone. Here are some of my ideas, some are stolen from the Plone project suggestions: I think it's important (for Google) that it's the Plone Foundation that has been approved for mentorship, not Zope Corp or the Zope Foundation (if there is/will be such a thing...). That means that what you do under this guise needs to be directly relatable to and beneficial for Plone. 1. Finish the ZSCP site[1] I think that the ZSCP process will be vital for controlling software quality in the future and provide people with a valuable resource for additional Zope software. My original proposal was modest by design, since I did not anticipate to have much time to work on a larger vision. With the SoC project I could finish the implementation of the proposal and extend the scope to be more inclusive of existing packages/products, especially with regard to Plone. This project would fit the SoC program well, since its scope is well-defined and extensible. .. [1] http://mail.zope.org/pipermail/zope3-dev/2006-February/018319.html I have two reservation about this - the first is that the process seems very arduous (i.e. there are a *lot* of tickboxes in that table, and there is the potential to create a lot of red tape). The second is that without a large amount of buy-in from the wider community (and in the context of SoC, that means primarily the Plone community), it won't gain the necessary traction to be relevant. To be sure, I support the principle of the ZSCP, but it is a very hard *social* problem (as opposed to a purely technical one) that may not fit the model of a single student working on it for a few months. As I recall, much of the process was also biased (for good reasons!) towards pure Zope 3 products, which may actually mean that the majority of Plone components could never fully comply with the standard... which in turn doesn't make for a great case of the Plone Foundation Summer-of-Code application. :) 2. Implement Local Sites in ZCML I already mentioned this several times: It would be very nice, if we could define local sites in ZCML. I understand this task very well and could write a proposal and implement it in a well-defined time frame. BTW, this task is a must happen, if we want to port something like Plone to Zope 3 eventually. This project might be too short for the Google SoC. But I think it has a lot of potential. I think that anything that solves one or two of these for Zope 3 would be highly relevant to Plone: - Local-ness - everything in CMF/Plone is about local. Only when product X is installed should X's functionality be exposed, and before X is installed, something that's registered in ZCML or whatnot could possibly break. People expect to have several Plone sites in one Zope instance and configure them differently. I'm not entirely sure how this fits with ZCML, though, since ZCML is inherently global (i.e. we can't hard-code site names in ZCML ;-), but I'm guessing you're talking about a more generalisable way to install things locally and have things only take effect when locally enabled? - Through-the-web customisability of *templates*. I'm not convinced we need TTW-classes and components and logic - those things fit progammer minds and programmer minds don't mind filesystems and like svn. But people using Plone are *very often* drawn to it because the ease with which they can override/customise page templates (and by extension visual logic, layout, etc.) without leaving their web browser or learn a large stack of technologies. It's not an ideal model, and we need good ways of getting out of the ZODB and into a skin product or similar. But we are extremely reluctant to make use of views with page templates (as opposed to page templates that acquire views and then call its methods) in Plone precisely because it means sacrificing TTW customisability. 3. Optimize ZCML We talked about it many times. The startup time for Zope 3 is too long. In part this is due to the schema field conversion and verification of the ZCML attributes. I would like to work with Jim on some strategies to optimize the startup time by reducing the ZCML processing.

That's like so many b-trees you can't see it for them? :-) Yes, it's a simple, reasonably-well-tested building block that aggregates multiple btrees into a single dict-like interface. You can decide whether you want to see the trees, or the forest. We've used it for two very different purposes: - the guts for simple rotating caches (here, the forest is the engine for the public API, and the trees are just used internally as the buckets that can be cleared and rotated); - the guts for an object that should be seen both as an aggregated container for all jobs, and as an object with two discrete child containers for active jobs and for completed jobs, respectively. I think many of us have written similar code (especially the cache with rotating buckets). It's simple code. It's a generic task, though, so why not start with a shared, tested engine? But anyway, it's only in the core because we didn't have the mini- package story when we packaged it: it's never been in a release, AFAIK.
