Note that the scolding had something to do with you breaking Plone trunk due to a transitive change in Chameleon, and the realisation that from this point on, any package shared between repoze.bfg and Plone (or anything else) that is configured with ZCML, will probably need to be forked. We found a workaround with Chameleon, but not one that will scale. The fix is totally scalable and completely correct. Chameleon.zpt just does not have any (real) ZCML anymore. Any package that has ZCML is, by definition, written for some framework as stuff that is meant to be overridden, otherwise it wouldn't be written as configuration. ZCML is unlike code in this way. If it wasn't meant to be overridden, it would be in code. All packages which are meant to be maximally useful outside the scope of that framework should be split into two things: the library portion, then some portion that contains ZCML for gluing in to some framework that wants ZCML in some specific configuration. When I read Martin's post, I had a similar reaction. Namely, that the convenience of the Uberthing (Plone in this case) will always trump the desire of packages trying to survive on their own for new audiences. At the time of the configuration scolding, I remember thinking: there's little interest here in Chameleon's goal to be bigger than Zope. Keep things convenient for us in Plone! Package sharing between repoze.bfg and Plone should not mean that BFG gets dragged down, paying for things it specifically doesn't want to eat. BFG never claimed to sign up for Plone's contracts. I sense the logic of Chris's position: if the Zope Framework is as big as every current use case in Zope2+Zope3+Grok+etc., with nine years of accumulations on each (3 forms systems in one of them), then we're missing the goal (IMO). We'll make life incrementally better for ourselves, but we'll still scare off the folks who aren't after Uberthing. Plone is going towards a smaller-and-smaller core that is only as big as the manpower to do a great job at keeping it stable. Meaning, very small. Hopefully the Zope Framework is a tiny little thing that pays only for what it eats. Hopefully the goal is to make a very good microframework (or even better, set of libraries). If you can't make the best configuration language possible because one line of includes to get trusted adapters is an unconscionable burden is the rule, then I know how this movie ends. --Paul ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

For that, it needed/wanted a configuration language that met your statement I don't like to have any code...I don't use.

The word Zope will continue to have its previous series of semi-competing meanings. The word will now also be attached to Framework, which will be the emphasis.

In the past, the Zope community hasn't made it a goal to be a sea of autonomous components. Its goal has been: top-to-bottom app server. We now have (I think!) said those goals are now in scope. Those goals are currently being met using the same name as the assembly. Trying to achieve the goals of the components, using the same word as the assembly, might not be the best way to achieve those goals. The comments I got on my pro-Zope weblog post showed that, if we *do* care about these new goals, we should consider whether the name is a barrier *for the components*. Alternatively, we could say: The components should only be used in the Zope application server. Perhaps that's the goal.

No, I think I understood you. I was being sloppy in my use of language. I should have said something more like Zope 3 then becomes an application server built around the Zed library. Good clarification. I think that Z3 is better than Z2 in a lot of ways. I also think that Z2 is more mature and complete. I really want us to combine those efforts. I think we've achieved enough and learned enough with Zope 3 that we can now bring that to bear and make Zope 2 better, refactoring the cruft away and applying the lessons we've learned with Zope 3. (Note that Zope 3 is not crust free.) I don't really care what this thing ends up being called, except that it *must* be called Zope. Yes, I agree. Zope is the app server. I think that is consistent with the past use of the brand. Yep. This paragraph makes me think I was clear. Yes, we need to follow Ian Bicking's advice and release our technology in bite-sized chunks. I'm hopeful that the packaging efforts underway will lead to more of that. Yes, and the use of the new name Z or Zed is a way to emphasize that the Zed library is NOT a big, monolithic app server; rather, it's something new and cool. I think this brings up an interesting paradox in the discussion. We want Zope to continue being the name of an app server. But we also want the CA to be perceived as usable outside of an app server. Outside of Zope, even. Thus, we are using the same name used to convey: It *is* an app server! It's *not* an app server! I think this might be a contradiction and might be worth discussing.

[Zope] ANN: Zope activities at EuroPython 2005, Jun 27-29, Sweden
Hi all. We're planning some Zope activities at the EuroPython conference next month in Sweden: http://www.europython.org/ In short, we have: o The Zope track, with over twenty presentations covering CPS, Silva, Plone, Zope 3, and other Zope topics. o A keynote by Tres Seaver, creator of the CMF. o A closing panel on CMS like last year. o A dedicated Zope Lightning Talks session. o A Z3 ECM sprint just beforehand with hands-on workshops for specific topics. This year has more Zope packed into it than any previous EuroPython conference. Particularly with the recent activities in Z3 ECM, there's lots of don't-miss stuff this year. Please register soon and get involved! More details for each of the items on the agenda. Zope Track -- The Zope Track this year has a spotlight on each of the CMS projects for Zope. Particular focus is given to the work being done with Zope 3. The talk listing is now up-to-date with the accepted talks: http://www.python-in-business.org/ep2005/alisttrack.chtml?track=694 Zope Keynote - In keeping with the emphasis on content management for Zope, the keynote this year will be given by Tres Seaver. Tres is the creator of the CMF, upon which CPS and Plone are based. He will be talking about the impact of Zope 3 and the ongoing work to make a shared CMS layer in the Z3 ECM project: http://www.palladion.com/home/tseaver/obzervationz/europython_2005_invite Z3 ECM Panel - This part is a bit of vapor-talk, as the panelists don't even know about this yet. wink Last year the track ended with a panel discussion in which the leaders of major CMS products for Zope discussed the impact of Zope 3. In particular, could the projects collaborate in a way similar to the CMF? The audience participated quite a bit and Jim Fulton led a very useful discussion. This panel then led to the Z3 Castle Sprint in 2004 and the Paris Sprint several months ago. We now have a project setup for the Z3 ECM effort: http://www.z3lab.org/ This year's panel will be a place for the Z3 ECM team to inform the audience about the shape of the project and solicit feedback about goals and objectives. Tres will be the moderator this year. Zope Lightening Talks -- Following the Faassen Format for lightening talks, this session is meant to be fast, fun, and slightly raucous. Lightening talks allow topics to spring up during the conference and get ten minutes of fame. Z3 ECM Sprint - There are several sprints getting organized at EuroPython. The Z3 ECM team is planning a pretty serious effort to kickstart its activities. The Z3 ECM sprint starts at noon on Thursday, June 23 and goes through Sunday, June 26. Tres Seaver will be the overall sprint leader. Topics include: o Florent Guillaume ([EMAIL PROTECTED]) is leading a session for a Zemantic-based repository, with relations covering versioning, multilingual content, and more. o Julien Anguenot ([EMAIL PROTECTED]) will lead a team working on the the ECM workflow architecture and continue the existing prototype. Discussion about the WfMC standard and the 3 architecture layers (xpdcore/wfmc/ecmworkflow) plus the existing work on the Zope 3 trunk is planned. o Paul Everitt ([EMAIL PROTECTED]) will lead a hands-on workshop for Model-Driven Ajax. This will be a start-to-finish walkthrough of creating dynamic browser applications using XML, JS, and XSLT. Focus will be on a productive workflow for UI development. This workshop starts on Saturday. If you are interested in one of these topics, please contact the the people individually. If you are interested in leading a session, email Paul. --Paul ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

How did you do that part? --Paul Dieter Maurer wrote: Dear Zope developers, we have used Zope+CMF+Archetypes in a new way -- not as a Web Application framework but as a framework for desktop applications that share a large part of their functionality with online applications (implemented with Zope+CMF+Archetypes). A major stumbling block has been Zope's incredibly high startup time. We observerd times in the order of a minute on computers with either slow CPU or slow IO. This may be acceptable for a Web server but is prohibitive for a desktop application -- especially as the predecessor application started within a few seconds. To overcome this obstacle, we tweaked Zope and fixed Python's import mechanism such that Zope now starts either out of a ZIP archive or as a frozen application. These measures had the following results. Startup times on a mid range computer (AMD Athon 1.4 GHz; 512 MB memory) with a standard IDE disk. Cold start Warm start (after computer startup)(most files in OS cache) File system13s5s ZIP archive 8s4s Frozen 5s3s In more details, we did: * implement a package for a new kind of urls pypackage: for package relative access to resources. The package monkey patches Python's open, os.listdir, os.stat to provide transparent access to pypackage: identified resources. It currently support package relative access for packages loaded from the file system, from a ZIP archive and from the executable itself (i.e. frozen packages). In the last case, the resources are in a separate ZIP archive. This package might be interesting for Python as a whole as it is not Zope specific. * implement a shared object importer to be used as a Python meta_path hook. This importer allows to load shared objects into the context of a parent package (such as e.g. ZODB.TimeStamp) although the shared object is not located inside the package's source (ZIP archive or executable). * fix about 70 occurrences in Zope code where package relative access was implemented by dirname(__file__) to consistenty use package_home. * modify about a dozen places in Zope+CMF to use pypackage: and cope with __path__ not being a list for frozen packages * fix a few products (Archetypes and friends, TextIndexNG2, PlacelessTranslationService, ...) to use package_home (rather than dirname(__file__)) and not to change the current working directory (which obviously would fail for destinationsbe in a ZIP archive or the executable). * implement lazy loading of ImageFiles to reduce the risk of recursive imports (and reduce startup time). * support lazy product initialization * support configuration from a pickle file (to avoid expensive parsing of the schema and configuration files). The pickle is used as a configuration cache. * fixed Python's import mechanism not to treat ZIP archives as a directory when the archive could not find a module. If you were *really* interested in these startup time improvements, I could provide patches which might be integrated in the Zope core for e.g. Zope 2.9. ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

[Zope-dev] Re: RDF Musings and TinyTables
Good grief, how did I miss this!! Shane Hathaway wrote: I just read the RDF article published here: http://www.xml.com/pub/a/2003/02/12/rdflib.html Yes indeed, that is a very good article. I've understood the mechanics of RDF for a while, but never understood what makes it better than what we already have. Now I think I get it: RDF theory is a new kind of database abstraction. It's similar to a relational database in that you put pieces of data into the database and later search for data. But it's much more ad-hoc than a relational database. I think you are 100% correct, maybe 110%. :^) In the last two years I made several attempts at grokking Mozilla and RDF was always the wall I ran into that prevented further progress. In the last three months I slowly, surely, forced myself to study it. Write things down, take notes, rewrite them down, etc. The light bulb has definitely gone off for me now, and I see things exactly the way you describe it: 1) It's an abstraction. Once you start working with it, you realize what this means. You take a bunch of information and throw it into a bucket. You also throw in how the information relates to each other. 2) It's a database. You have a pretty formal way of asking questions and making sense of the stuff in the bucket. You also have a way to put things in the bucket, and also to rearrange the stuff in the bucket. 3) It's ad-hoc. You don't have to know everything beforehand like SQL. You also don't have to control the containment hierarchy like you do with XML. (Took me a LONG time to realize the significance of the latter point.) The ad-hoc part is, for me, the key. Relational theory provided the theoretical foundation for modern online transaction processing. But things like content management are a much different problem. (One analyst states that unstructured content is 80% of the information in a business.) RDF, in my view, is the equivalent of a set theory, a formal foundation, for content management. Without it, everyone has to build their own framework for stitching things together, for connecting the dots. Serialization of RDF into XML and the relationship between RDF and the Semantic Web are distinct concepts from RDF theory. That's right. I've always been surprised when I threw some RDF/XML into Mozilla, then got a dump of the serialized results. What I put in doesn't look like what I get out. That's because there is an abstract model. The XML can look a couple of different ways, and you still have the same abstract model. It took me a while, but I learned how to take advantage of this. With Moztop, I'm taking a pretty loose, distributed approach to content managment. I collect RDF from a bunch of different servers, throw it all into one big graph, and use this to draw widgets on the screen. The ability to make an assertion into a completely different part of the tree is something you can't do in XML. This ad-hoc data storage made me think of TinyTables. TinyTables is a good Zope product that fills the need for simple tables of data, but it needs attention. What if it got replaced by some Zope product called I will do everything in the universe to help such a project. How is that? :^) I know what the practical benefits that RDF can mean for content management. And it isn't esoteric Semantic Gibberish. I'm unable, though, to map it on the server side. However, I'm having luck on the client side: http://www.zope-europe.org/Members/paul/tmp/moztop-pinstripe.png RDFBucket? An RDFBucket object would let you input data in a variety of ways, including object introspection, forms, and XML with embedded Yes, this is very similar to the client side model in Mozilla. I'm doing things like: o Assembling a hierarchy o Making up new hierarchies where none existed before o Generating property sheets o Doing conditional display o Making rich connections between loosely-coupled objects, meaning, objects that didn't expect to be coupled o Allowing data from Zope 2 and Zope 3 sites to be collected, presented, and related in the same interface Mozilla's template model is interesting to at least investigate. What's interesting about it is the way you can follow relationships in the model to draw things on the screen: http://www.mozilla.org/docs/xul/xulnotes/template-primer.html In this very simple example: http://www.mozilla.org/docs/xul/xulnotes/template-bindings.html ...note the last two resources shown in friends.rdf. Instead of repeating information in every row, you get the equivalent of a join. Except the result of that join can produce another join. The template builder keeps following relationships. Also, you can join to something on another server. RDF. It would let you run queries similar to ZCatalog. Maybe it would also generate RDF for embedding metadata in web pages I'm wondering if I'm thinking in line with RDF theory,

In fact, the reverse is true: ZC is focused on content management, but ZC realized others want to do different things with Zope. Thus ZC didn't turn Zope into a CMS-exclusive thing. Doing the CMF outside of Zope allowed the CMF to make rapid progress in a focused area without making promises that Zope itself would have to live with permanently. This has worked perfectly. We all now know a lot more about the patterns of content management. We can now refine them, and refine Zope, with the work on Zope 3. Tell me, do you think KDE should be merged into X11?

Zope is a tool. Things like Silva and Plone are products. The purpose of Zope is to allow people to build things like Silva or Plone, or things quite different (perhaps custom to their own needs) quickly. And frankly, tools don't sell themselves. People want to see glitz. You could argue that Zope should be the project/brand with the glitz.

The EuroPython 2002 conference, http://www.europython.org, is in Charleroi, Belgium.

However, we would like this sprint to attract a group of people that are committed to participating in Zope 3 after the sprint. If your interest is simply in learning about Zope 3, there is a tutorial the first day of the conference that might be more appropriate. The requirements are simple: you need to know how to develop in Python. Even Zope experience isn't mandatory (though it is quite useful.)

Re: [Zope-dev] how bad are per-request-write-transactions
ForkedStorage, I like it simply for the coolness of the name. :^) But it sparked a different kind of idea, leveraging a pattern that might emerge in Zope 3. Let's say we had a queue in Zope. We could asynchronously send changes into the queue. Later, based on some policy (e.g. idle time, clock ticks, etc.), those changes would be enacted/committed. Imagine the queue itself is in a different storage, likely non-versioned. Imagine that the queue is processed every N seconds. It takes all the work to do and performs it, but in a subtransaction. Thus you might send the queue ten increments to a counter, but only one will be committed to the main storage. To make programmers have to think less about the queue (send in the object reference, the method to use, and the parameters), you could make it look like a special form of subtransactions. That is, you say: tm.beginQueuingTransactions() self.incrementCounter() self.title='Simple change' self.body = upload_file tm.endQueueingTransactions() At the transaction level, all enclosed changes are queued for later commit. You don't have to think any differently than rather object state management. This pattern applies better when you have a lot of document cataloging to be done. A separate process can wake up, make a ZEO connection, and process the queue. I don't think that indexing documents *has* to be a transactional part of every document save. Under this cron-style approach, you also pay less of a conflict-error penalty, as you can increase the backoff period. There's no web browser on the other end, impatiently waiting for their flaming logo. :^) Ahh well, fun to talk about. Maybe this time next year we can repeat the conversation. :^) --Paul Shane Hathaway wrote: Jeremy Hylton wrote: CM == Chris McDonough [EMAIL PROTECTED] writes: Completely agreed.

I'd really like to do this for ZODB4, but it seems hard to get it into FileStorage, without adding automatic incremental packing to FileStorage. Example: Object A is marked as save enough revisions to do a single undo. When a transaction updates A and makes older revisions unnecessary, there's no obvious way to remove them without doing a pack. We could write a garbage collector that removed unneeded things (as opposed to packing everything to a particular date), but it doesn't seem very useful if it needs to be run manually. One idea I've been floating in my head is the idea of a forked storage, where some objects are stored in an undoable storage and others are stored in a non-undoable storage. I could try to explain it in English but pseudocode is easier: class ForkedStorage: def __init__(self, undoable_storage, non_undoable_storage): self.undoable = undoable_storage self.non_undoable = non_undoable_storage def store(self, oid, data, serial): if not serial or serial == '\0' * 8: # For new objects, choose a storage. want_undo = self.wantUndoableStorage(data) if want_undo: storage = self.undoable else: storage = self.non_undoable else: # For existing objects, use the storage chosen previously. if self.undoable.load(oid): storage = self.undoable else: storage = self.non_undoable storage.store(oid, data, serial) def load(self, oid): data, serial = self.undoable.load(oid) if not data: data, serial = self.non_undoable.load(oid) if not data: raise POSException, 'data not found' return data, serial def wantUndoableStorage(self, data): u = cpickle.Unpickler() module, name = u.loads(data) class_ = getattr(__import__(module), name) if getattr(class_, '_p_undoable', 1): return 1 else: return 0 Only a simple idea. :-) Also, how would you specifiy the object's packing policy? I'm thinking an _p_revision_control attribute or something like that. If the attribute exists on an object, it sets a particular policy for that object. Do individual transactions need to play in this game, too? I'm imagining a use case where an object is marked as no revisions but you want to be able to undo a particular transaction. I'm not sure if that means : - you can undo the transaction, but the no revisions object keeps its current state. - you can undo the

Zope 3 needs to make it possible to build YABB, interfaces which support all browsers while still looking slick, etc. However, it is important to note: Zope 3 is *not* a product. It is used to build products. The core ZMI is needed to the extent that it helps build or administer products. Thus, Zope 3 is not like YABB. Of course, Zope 3 can ship with one or more sexy sample applications, like YABB. But if we blur the line for Zope 3's ZMI, we'll be right back into the core problem of Zope 2's ZMI: audience confusion. One of the first questions to ask when building an interface is What is the audience? Giving a very focused, tough response can greatly boost effectiveness.

[Zope-dev] Q: Anyone want to sprint in Fredericksburg next week?
Howdy. This is a last-second email aimed at Washington-area Zope developers that might want to do a Zope3 extreme programming sprint with Jim next week, here in Fredericksburg. The dates are any two of Dec 26/27/28. Good knowledge of Python and Zope development required.

[Zope-dev] Re: My thoughts on the development process
I've taken a while to respond on this, because I wanted to talk it over with folks here, to think about the specifics of what different ideas would mean, etc. In summary, your last paragraph says: So let's trade in some risks to the Zope core development (rash action and messed up stuff happening once every while), in exchange for a lot more active contributors. We agree, and it's my job to get us there. Here's the next level of specificity: 1) Lighter weight process. Brian and I have talked about it, and we agree that we should investigate ways to lower the bar on ceremony, *without* abandoning organization. However, we both feel that, as you noted, the ultimate issues lie elsewhere. Thus... 2) Improve the tools. There's merit to the argument that the state of the fishbowl isn't very discoverable nor usable. Folks on zope-web know that we're proposing work that we'll do. Also, we are open to work that others will do. 3) Delegate leadership. This is, IMO, the most important thing. We need more people in the core, leading important areas and making decisions. For ZC, this really means that we have to trust the trustworthy and accept the paragraph of yours I quoted above. 4) Find the leadership. We can't sit passively by and say, We opened CVS and nobody's done anything. Somebody has to work specifically and repeatedly to bring people in, make sure they know what to do, and perhaps even prod them occassionally to get working. This takes publicity, promotion, cajoling, communications, and all kinds of other things to get the momentum going. I've signed up for the last part. In general, I'm sure everyone is pretty talked out on this subject and ready to see some action and results to go with all the voluminous emails. Me too. So let this general state of the problem discussion rest for a while, and let's work on some of the good ideas already discussed. --Paul Martijn Faassen wrote: Hi there, I've read parts of the open letter threads just now. There's a lot of talk about how if only we have better tools the whole process will go better and Zope will get more contributors. That's a typical hacker response, and I do this myself as well. Throwing more technology at a problem doesn't always make a problem go away. And though technological solutions to social problems are nice if you can have them, and we should look for them, they don't always work. I'm not convinced more technology will make the dead fish problem go away. I think the contributing process is in fact too heavyweight. It should be easier for people to get in drastic changes to Zope. The only way for people to take more responsibility if they can actually have it. Only a few people will take it, but that's more than what is possible now, with possibly the single exception of my taking responsibility for ParsedXML. And until recently I was still in the position of doubting whether I really had it formally, not just de-facto. I kept asking for approval and guidelines from the official maintainers, but they were too busy (no blame to them), so I went on anyway and did a release eventually. I dread having to go through the fishbowl to add in my 'node path' implementation to ParsedXML. I've done the design work, I've implemented most of it, and I feel I'd have mostly wasted time writing a fishbowl proposal. I hadn't even explored the problem enough to be able to do that. I needed to prototype it to understand it. I've discussed some issues with people locally and and on the Zope-XML mailing list. And I'll probably release a version in a few days. Perhaps adding Formulator to the Zope core would be nice eventually. But going through the fishbowl bureaucracy would take forever. I only have so much time to spend on it, and I'd rather spend time improving the product itself. And now look at how the Zope core is actually being developed. Sure, there's lots of stuff in the fishbowl about what the Zope future should be like. Plenty of stuff, though some stuff is rather hard to find. But I have a lot of praise for what the Zope Corp people have accomplished it it; it's a lot better than having no such thing at all, even if it's only used as a notification service in part. The main thinking about the directions of Zope is not done in the fishbowl or on the lists, it's in the minds of the talented people at Zope Corp and in the brainstorm sessions they hold together. That's the natural way people work. I work that way too. Such a process can occur on mailing lists as well, but it's very hard to break into it. I've tried several times. I'll keep trying as I'm convinced it's possible, but it takes a lot of persistence. Time will tell. On the Zope-XML list I just post regular updates about my thinking to encourage discussion, and sometimes that works. So what am I trying to get at with this mail? One thing is that the process is too heavy-weight right

Though you'll pay your own freight, we'll supply a spacious cubicle. :^) If you're interested, contact me. Second, Jim is hoping to go to Europe first or second week of January to do two sprints. The first is with a small (3 plus Jim) group to resolve the internationalization bottleneck and get Zope3 to do i18n and l10n. This first group will then help Jim do a larger (maybe 8) sprint the subsequent two days for other people in Europe. We haven't yet arranged for facilities. Third, we'd like to host an open house on the Thur and Fri after IPC10. Besides an open house, we'd like to have perhaps a massive sprint. Just to point out the obvious...this is a sign that we're listening on this discussion and trying to lessen the difference between ZC and the community. With Zope3 we have a chance for key community people to shepherd important pieces of the architecture. These pieces can include XML, i18n, cataloging, package management, workflow, etc. At the same time, these sprints provide a working session with face-to-face communications. It's a high-bandwidth way to make sure Zope3 does what the community wants. --Paul ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Re: Fishbowl?
Joachim Werner wrote: I think that there ARE problems that can not be solved on a mailing list or in the fishbowl. One of them is doing a good general design (which we MIGHT need for some of the Zope 3.0 issues). I followed all the stuff about the CMF and formerly PTK and knew that it was heading to a direction I didn't want, but at the same time I felt that it would not help if I just contributed to the mailing list. Maybe this was a personal problem of mine, but I don't think so. I don't think so either. I think your paragraph above does a wonderful job of concisely summarizing the challenge. First, there shouldn't be Annointed Tools. We should strive to have good tools, and we should strive to use good tools, but the real goal is communication. If the current approach isn't hacking it, we need something else -- which could mean we learn from successful patterns in other projects. Second, when communication reveals an issue -- what happens? Let's say that every single person in the world of Zope agreed that the CMF was going in a wrong direction (just for the sake of argument, as the CMF has people that like it as well as dislike it). Would anything actually happen if consensus was reached, and who would be the ones to convert conclusion into code? Third, as Brian pointed out and you conclude with in the paragraph, frustrated people tune out. This causes the other side of the communication to get frustrated and stop communicating. Then things break down. It's important to recognize this is happening, put aside the frustration, and address the problems. IMHO, there are two possible approaches to problems like that (major design issues I mean): a) dictatorship, if the dictator is really good in his job (e.g. Jim Fulton has done a great job with regard to the design of the ZODB ) b) meeting in real live (or at least in real time) Some of the core architecture of the KDE KParts component model was developed on the KDE 2 conference AFAIK. I think we might have to do sessions like that at the upcoming Zope/Python conferences ... That's a very good point. It's even a good point inside ZC. Getting ten people in a room for an extreme programming session has done wonders for our ideas on Zope3.

Re: core i18n support (was [Zope-dev] Open Letter to zope-dev)
As both Robert and Joachim (in another message) have noted, core i18n support is blocked by a single issue: there are two different approaches and insufficient consensus about resolving them. The first criteria that I have is whether someone is willing to become a CVS contributor and shepherd i18n in a responsible fashion, as Martijn Faassen has done with XML. In this sense we suffer from an embarassment of riches: both Localizer and ZBabel have people willing to step up and provide leadership. Unfortunately there isn't someone with sufficient authority on the subject to annoint one as more right than the other. And an arbitrary decision by ZC is sure to leave hard feelings. Unfortunately this needs to get cleared up soon, so that an i18n team can start influencing the component architecture. I suggest that Stefane and Juan David (Localizer/Nuxeo) and Stephan, Andrew, and Joachim (ZBabel/iuveno) have a little chat and make a recommendation for a small next step. --Paul Robert Rottermann wrote: Andreas, sorry if I have not reacted to a questions for assistance in the realm of i18n.

Re: [Zope-dev] Open Letter to zope-dev
Agreed completely on both of those points. There's double good news on both: 1) Someone plans to do something about it. 2) Both are with community involvement. On documentation, someone in the community has committed to taking over the Documentation page on zope.org and finally organizing the myriad of useful, but unlocatable, doc resources out there. The second is pretty exciting as well. I saw a presentation in Paris by Juan David Palomar, of Localizer fame. (The presentation is now up at http://estce.act.uji.es:9673/localizer). The presentation impressed me on the need to get someone into the core of Zope that knows all these details, but also convinced me that the Zope3 effort needs to anticipate the needs of i18n and l10n. I spoke with the guys here doing the extreme programming session on Zope3, and they agreed. To say it again: 1) I think the world of Zope needs to grow 10x in the next year. 2) ZC can't do it, and much of the action in Zope is non-U.S., particularly Europe. 3) Thus, Zope needs a strong, competitive internationalization story.

I have read all the all the mail that has been stirred by that open letter. I agree very much and I am willing to contribute as much as I can that zope should grow 10x. I found two things missing in the discussion so far that are crucial to attain this goal: - documentation To start using Zope doing something more than trivial is an incredibly frustrating thing. Hunting for the right piece of documentation is very very hard. The community is very helpful I agree readily. However asking it should be the last resort and being forced to use it as an important part of the developement effort is very cumbersome and time consuming. And does not really take the frustration out of the process. Bruce Eckels postings to this list show that even a developer of his statue is prone to the same effect. I am a seasoned programmer that started to deal with Zope exactly one year ago. It is only now that I learn where to look for what piece of information and to decide which one is relevant and which one is not. - translation support Internationalisation is crucial. English in the user interface is just not tolerated in a non English speaking part of the world. It is 10 years ago something like that would have been acceptable. I am from Switzerland where we pride ourselves to be multilingual (6 Million inhabitants 4 major languages, English being the fifth). However nobody would think of having anything like English on a public website. There are a number of efforts towards translation support.

I'd say sorting out the Fishbowl would be a good action to start with. You're going to love the irony on this, but there's a proposal in the fishbowl on this: http://dev.zope.org/Wikis/DevSite/Proposals/FishbowlManageability ...and of course, nobody knows the proposal is there. Now, I see options for this: 1. We can build something better. I can list requirements but that's not relevent here. However, this will take serious effort (it's a hard problem...) and as we know from bitter experience, things that need serious effort either don't happen, take far too long to happen or happen badly ;-) Yep. I'm in favor of some very small, very incremental steps. 2. We could by a tool that does this kind of thing. Where would we get such a beast from? how much would it cost/ who would fit the bill? ...and what would be the transition costs? 3. We could use another open source tool. Bugzilla springs to mind. Yes, it's not Zope, or even python, but it does work, certainly better than anything we, as a community, have right now or could build in the time it would take to install and set up. Hmm, I don't really see Bugzilla and the Fishbowl overlapping. Perhaps with the Collector, though. However, I don't think the real issues involved are related to choice of tool. It's been mentioning that ZC doesn't pay attention, so proposals go in and nothing happens. Bugzilla won't fix that problem. I'll add that the community doesn't always pay good enough attention. Sure, people will say when will we have versioning or when will we have web services. We go off, make a proposal, and email zope-dev. No feedback -- I take that back, each has received one response, whether by wiki comment, mailing list response, or private response. This isn't a good track record. Brian produced 35 pages worth of almost-flawless docs on web services to go with his code. But no comments. And he's doing this on his own time. So let's remember that this is a two-way street.

If you are writing a product that needs to create a user, you go look in User.py and find out what the API since that tends to be the only place the API is documented. If you look at how UserFolder is implemented; a) The change to manage_* seems to be completely arbitrary, since we already had _do* methods that meant you didn't have to call manage_users with fake submit buttons. So what is the point of having manage_ ? b) manage_* methods usually indicate web callable methods, which these clearly aren't (no docstring, no REQUEST parameter). In fact they don't return a status at all, so they seem to doubly useless. c) If it's an internal API for applications then the methods should probably be protected by being prefixed with an _ to indicate they're not for calling from the web or from within Documents/Templates. d) Even if you conformed to the API by calling e.g. manage_addUser() this seemed to be incorrect, since it didn't do things like encrypt the password. This meant you would have to either a) encrypt the password yourself (*very bad for XUF*), or b) call _addUser() which is not part of a defined API but looks like it should be (i.e. manage_addUser and _addUser seem to be reversed in functionality). ii) This is compounded by the fact you would have to query the UserFolder itself to find out if you should be encrypting passwords (what no UserFolder capability API?). e) s/_do/manage_/ doesn't constitute a new API. It's just the old one with the names changed. f) We've done a lot of work to make a flexible UF product that is I18Ned (well -able), and they still use the value of the submit button.

Re: [Zope-dev] not Python 2.2a1 but Python 2.2b1
An important aspect to consider: in some cases, you simply need the ZEO storage server to have large file support. Thus, if you can get the ZSS running under Python 2.2, then you're set. This is considerably less ambitious than getting all of Zope (e.g. the catalog) migrated to a new Python version. Also, since Barry and Jeremy (or, as we say, Barremy) are now calling the shots on ZODB and ZEO, you can bug them about it. :^) They're likely to care a lot about keeping everything in track with Python 2.x. --Paul Martijn Faassen wrote: Hannu Krosing wrote: Andy McKay wrote: Is out and: Large file support is now enabled on Win32 and Win64 platforms, and automatically configured (at least on Linux and Solaris). Cool, that will mean there will be less worries about Zope users hitting the 2 gig limit. But will Zope 2.4.x run on 2.2 ? No guarantees, but I do know the PythonLabs crew and the Zope development crew try to keep things working with 2.2. That doesn't mean there won't be problems, but I don't suspect it'll be as tricky as the move from 1.5.2 to 2.1. The main thing is that the Zope C extensions keep working, but that seems to be watched fairly carefully.

Re: [Zope-dev] ZPublisher/ZServer interaction (was Re: A modest proposal)
I don't know, there were quite a lot of ideas brought up. It started with a discussion of Twisted being swappable for Medusa. Since Itamar is a developer of Twisted, he should champion that effort (he knows a lot more Zope than any of us know Twisted). There was also a discussion about replacing Medusa by embedding in Apache. While Michel said we had thought about it, that's about the extent: we've thought about it. It isn't even scheduled for further thinking at this point.

Dieter Maurer wrote: Paul Everitt writes: http://dev.zope.org/CVS/Contributor.pdf The Committer Agreement does not seem to be even handed: The committer transfers rights immediately and indefinitely to Zope Corporation (the contributions become a gift to Zope Corporation). This is an inaccurate representation. Transfer means you lose the rights and we gain the rights. Under joint ownership, both have rights. I think this point was abundantly clear, so I'm surprised to see you portray this as a gift. The agreement states explicitly that no rights are transfered to the committer. Because they never lost any rights. This is not a problem in itself. However My intention to contribute would be to strengthen the Open Source Movement. A statement that the supported code base (Zope) will remain open source and that committers will be able to use it (indefinitely) under terms comparable to the current ZPL would help to let the agreement to appear more balanced I don't think it's really feasible to 100% guarantee things in the future. Rather, the agreement states that current code, and any contribution, will be available under the ZPL. Nothing can be retracted. If someone comes along and gives us one trillion dollars to stop releasing our work as open source, two things would happen: 1) First, we'd take the money. :^) 2) Second, all the existing code has to remain available under the ZPL. We just wouldn't do _new_ things under a ZPL. This is part of the safety of joint ownership. If you don't like what we do in the future, you still have rights on your contribution. The Commitrer Agreement is quite threadening: A committer takes over a considerable risk (complete warranty and indemnification with respect to intellectual rights infringement). Yes. You can't make the risk disappear. Someone has to bear the risk. It makes zero sense for ZC to bear the risk of what goes on in someone else's brain. Even in the scenario of carelessness, a case will have to be made regarding what you knew and when you knew it. The risk is far higher than that of a (german) employee. German employment law recognizes that * all people make (sometimes) errors * coping with isolated errors is far easier for a larger community (the big employer) than a single individual. Therefore, it uses the term Fahrlässigkeit (carelessness). An employee has to take all care to not make errors during his work. If something bad happens due to slight carelessness (leicht fahrlässig), then this is a general risk which has to be taken by the employer. If serious carelessness (grob fahrlässig) was the cause, then the employee has to take the consequences for himself. We should have something similar for the committer agreement (not restricted to intellectual property rights!). Maybe something like an insurance for slight carelessness cases... Unfortunately we'd have to be the insurer. :^( Otherwise, commiting anything might easily ruin an individual. Instead, you'd prefer that it ruin ZC? Or are you asserting that somehow we could make it so that nobody would be held accountable?

Re: [Zope-dev] RE: Barriers to Zope popularity: Part 2: source control
I'd like to add some misinformation...errmm, comments. :^) On the version control side, you're quite right, we're still behind on it. There _are_ some ways to get there, if you try hard enough. But that's unacceptible. There are two things long term that need to be done: filesystem synchronization and version control. The former is a project to make it possible to represent and perhaps round-trip Zope data in a way friendly filesystem tools and patterns. This obviously includes SCM systems like ClearCase. We've had, at our Friday jam sessions, a couple of proposals on this. So far it's simply provoked rigorous discussion but not a lot of consensus, as balancing the competing goals is harder than it sounds. I was talking with Jim yesterday over lunch about this, and whether the new component model would put filesystem synchronization in its scope. The short answer is, not in the first cut. It will certainly make filesystem synchronization a lot easier, but we need to get it out the door and tackle filesystem syncing later. Regarding version control...this is something that has been burned into our skulls in recent RFPs that we've responded to. It's the number one thing we at ZC need to address to be more competitive in CMS bids. So far the goals and use cases of DeltaV seem to best describe what we're currently thinking: http://www.webdav.org/deltav/ http://www.webdav.org/deltav/goals/draft-ietf-webdav-version-goals-01.txt http://www.webdav.org/deltav/scenarios/scenarios-00-1.htm Note that this is for Zope itself to have a model for version control. Filesystem sync is the most obvious way to interface to a separate SCM system. However, _if_ Zope adopted a repository model, it's conceivable that Zope could have an implementation of the repository that used an external system. _Please_ understand that this is all hand-waving right now.

It would be very helpful for me if you could give me some information on this issue, please. Hope you don't mind me CC'ing this to zope-dev. I still see both these issues as important and still see the lack of progress towards Zope working well in traditional development environments being a real outage. Plus others may have different opinions about the current state of affairs 1. I have not used Zope Page Templates but these are supposed to solve the wysiwyg problem. They are an alternative to DMTLDocuments. They allow for much better seperation of code and presentation. Get you graphics people to use webdav to edit the html with whatever editor they want and the coding people argment the html rather than rip it appart. http://www.zope.org/Documentation/Articles/ZPT1 Personally I like DTML and back then I did suggest a way DTML could used in a similar way to Page Templates (basically have a view mode of a DTML document that incorparates the rendered content as well as the DTML code such that when the page is edited and saved back, it will save all the changed parts back to the where they came from, i.e. the different DTMLMethods that made up the page). but like most of my ideas I din't have the ability or time to implement it. 2. Hasn't really been solved. There are sort of attempts that work now with CVS (I havn't tried it) http://www.zope.org/Members/sspickle/ZCVSMixin This but there are proposals that will better solve this problem, but no implementation on the way that I can see. The problem is really one of synchronization. You want two different representations that are both kept upto date. One for zope to use, one for all the reasons we have things under source control.

OK, a response. Sorry for the delay. First, I'll change the part of the introduction that says: Essentially, a committer signs an agreement stating that all code that the committer submits has been created by her. ...to say: Essentially, a committer signs an agreement stating that all code that the committer submits has been created by her, or that she has verified that the contributed code violates no rights. Which means that we're going to take you up on your suggestion for encouraging small patches. I just added this to the FAQ: 8) Does someone have to jump through all these legal hoops just to submit a small patch? The contributor agreement certainly is a heavy process for someone that wants to make a small contribution, such as a patch. These contributions are just as important to the health of an open source project as major code work. Thus, Zope should encourage patch contributions, not create an enormous disincentive. At the same time, integrity of the code base needs to be maintained. For small contributions, simply supply them through a communications channel such as the bug tracker or the mailing lists. Alternatively, contact a committer or ZC directly. A committer will then review the patch and assume the legal issues of committing it themselves. Likely they will contact the patch submitter and get a confirmation that the patch can be used. The committers will have some guidelines on recognizing when it is reasonable to accept a patch. It should be clear when something has little basis for being deemed intellectual property, versus a major change with advanced algorithms. In your note, you mentioned: I suppose that I could assign them those rights, but personally I find that idea repugnant since I don't believe in intellectual property grin. (Hmm. If I put my stuff in the public domain, how would that play in?) Repugnancy aside :^) your second comment is on the mark. It isn't so much that you need to assign and lose ownership. Rather, the committer needs to ensure that they aren't violating your rights. We'll probably work up some boilerplate such as, I'm going to commit your patch to Zope. It's going to be available under the ZPL and the joint ownership model of the Zope Contributor Agreement. Please respond agreeing that you understand the ZPL, the joint ownership model, and allow this contribution under these terms. How does that sound? --Paul R.

Second, I suppose you should be aware of my biases before reading anything more. I don't believe in intellectual property, either copyright or patent.

Also, I am not a lawyer and don't pretend to be very up on the subtleties of copyright law, so my concern may turn out to be naive. I very much like the intent stated in the Introduction, that of getting maximal rights into the hands of both the contributors and Zope Corporation to do things in the future with the code without having to get an endless set of sign-offs. However, I have a concern about the Agreement that isn't covered in the Introduction or the FAQ. I'm worried that the Agreement may exclude us from some of the benefits of the bazaar model of open source development. My key concern is summed up in this statement from the Introduction: Essentially, a committer signs an agreement stating that all code that the committer submits has been created by her. The actual agreement does *not* say this, but essentially it does require it, since the things the committer has to swear to in submitting the code are very difficult to swear to unless he or she is the author of the code. Now, I have only contributed small amounts of code to Open Source projects so far. But I'm sure there are a lot more people out there who have only contributed small amounts than those who have contributed whole modules, and that there are even fewer people who do so much work that jumping through these kinds of legal hoops, and agreeing to a certain amount of liability, is worth while.

Re: [Zope-dev] questions about writing a DA
I just took a look at ODBC Socket Server, which I had never seen before. Pretty interesting! Here's some comments. 1) It looks like socket server opens a new socket for processing every request. In this respect, it goes against one of the benefits of database adapters, which keep a persistent connection. 2) Architecturally, socket server is very similar to web services. See the fishbowl proposal at dev.zope.org for more info. Thus, the approach that Zope would do for web services might have some similarity to what you'd like to do. Alternatively, take a look at the adapter for Ultraseek search engine at http://www.zope.org/Members/brianh/UltraseekDA. It gives a model that might be useful to you. 3) Zope's approach of having separate objects that handle database connections provide the benefit that regular objects can't just fire up socket connections. You want a model that helps prevent all of Zope's threads from being stuck waiting on responses to socket requests. 4) SQL Methods provide some useful and important machinery for your socket server approach. First, I think you want site developers to think your thing is exactly the same as a regular SQL Method. Also: - You likely want to keep the arguments list approach, to prevent people from inserting malicious data into the SQL requests. - Even more than with current database adapters, you want to retain the caching feature in SQL Methods. - Shoving the results into the Recordset code is something you might want to keep. - Etc. Good luck, this looks like a useful project! --Paul StevenLee wrote: hi,all I have got several questions here,and maybe you can give me some advice. What I am trying to do is write a product which can communicate with ODBC Socket Server, a win32 server application that allow applications to have access to Data Sources managed by Windows ODBC DataSource Administrator. And now a class written in python can communicate with ODBC Socket Server. BTW,the class mentioned above handles the connection to the server,sending SQL statement,and Receiving results. As far as I know, in Zope,to access Data Sources,one must create a Database connection and ZSQLMethods associated with it to get the results. (but I have doubt about this, IMHO,there must be some other way to do so,but what is it.). Now,I am rather confused about how to solve the problem. First,is what I need to write a DA? or just a common product? Second,if it's a DA, how can I use the existing class? I have read the article named how to write a DA in the how-tos,but it is quite abstract to me. Third,where can I find more about the DataBase Connection and ZSQLMethod ? especially on how they work together to access databases.

Re: [Zope-dev] ZPL and GPL
With great trepidation, I add a post to this thread. As Barry has mentioned, this has all been discussed a LOT. I'll try to summarize and clarify a few points: 1) I wanted to specifically address something in Michael's post here. We fully expect people to profit from Zope, even if that means for-fee, intact redistributions. They simply have to provide credit. Others may have a different philosophy, but that's ours. This is similar in some regards to Perl's and Apache, I believe. 2) We specifically expect to produce a packaged version of Zope. It's clear that it's the only way to appeal to the mainstream market. We hope others do the same. 3) Regarding other posts, our license is nearly identical to Apache's license, close enough legally to say it is the same. Therefore, to say Zope isn't free enough is to say Apache isn't free enough. Anybody that says that loses a fair amount of credibility, at least with me. Apache is an example of a crossover success (open and commercial) that I think provides a fantastic role model. 4) Any changes in the license are likely to be more in the direction of an Apache-style license. No approach pleases everyone, unfortunately. We do the best we can. --Paul Michael R. Bernstein wrote: On 26 Jun 2001 10:29:39 +1000, Anthony Baxter wrote: Michael R.

Given how important this is to Zope's growth (and to DC's growth, as a result), this is far far more important than the karma from switching to the far less flexible GPL You're right. I hadn't considered that the ZPL needs to be 'proprietary compatible' so far as add-on products are concerned. perhaps the LGPL would suffice, as that would permit creating proprietary Zope products. But I won't be entirely happy if the ZPL permits proprietary third-party redistributions of Zope itself. Your argument seems to be that DC would want to control other companies ability to make distributions derived from Zope - unless they've been hiding this nefarious plan from the community, this doesn't seem to be an objective for them. Heh. I guess I shouldn't have stuck that in there. An argument I've occasionally heard for BSD-style licenses is that the original (usually corporate) author wants to be able to make proprietary releases based on other peoples contributions. The argument for NPL-style licenses is that they (the original author) want to be the *only* one with such a privileged position. DC has never indicated that either of these was important to them. As far as a contributor to Zope wanting to keep their work free, then if the ZPL is GPL compatible, they can make their components GPLd. True.

Re: [Zope-dev] ZPL and GPL
I'd like to add a quick clarification, then I'll reply more later. Frederico brought up a good point that indicated I wasn't clear. It is a *desire* of ours to be GPL-compatible.

Some quick points on this. First, feel free to talk on this list about ways that Zope developers can license their stuff. It's a constructive discussion, and since I'm not a Zope developer, I can ignore it. :^) Second, regarding the licensing of Zope itself, ChrisP is right that I'm the guy on that. Or more specifically, Hadar Pedhazur (our board chairman) and I run the zope-license email alias. He and I had previously decided that, after the round closed, we'd take a fresh look at our licensing strategy. Basically, we'd like to get out of the business of having our own license, and we're open to the idea of a license that is more GPL-friendly, in the spirit of Apache, Python, etc. Thus, continue discussing what you need to do your jobs and give us some time to hash out a proposal.

[Zope] FYI: Digital Creations secures $12M round of investment
Hello Zope friends. At long last we at Digital Creations are able to publicly say it: we've closed a $12M round of investment: http://www.digicool.com/News/CRound.html It's out on the newswire now. We'll start pushing it out more over the next 24 hours. This, needless to say, is a big deal, one that we've worked on really, really hard this year. With the tech market downturn since March, and with Open Source particularly getting a beating, it's vindicating to get good funding from strong partners. When everyone else was getting wads of cash during the go-go times, we were quietly at work, being frugal, making money, making a business case, and being profitable. We're proud to say that we got our money when money was hard to find. Let's put it this way: Open Source business is hardly dead. It's just different, and better. What will this mean? First and foremost, Zope and Digital Creations will become very competitive, very quickly, along a number of axes. As the PythonLabs move indicated, we are taking aggressive steps to become a dramatic force in the worlds of content management, web application services, and Open Source leadership. With this round, our business model has been validated. As a member of the Zope community, I view this as "the dream delivered". Many of us care deeply about this thing we're involved in, and sometimes it feels like a longshot. Though this is still a David vs. Goliath, David now has a slingshot, and a bit of steel in his eye. Thanks go to the folks here at DC, to the Zope and Python communities, and to the companies around the world that are basing their business on Zope.

At BeOpen, we've done several good things for Python, such as moving the Python and Jython development process to SourceForge, and the successful release of Python 2.0. Unfortunately, BeOpen.com's original plans for PythonLabs didn't work out as hoped, and we weren't able to reach mutual agreement on workable alternative plans -- despite trying for months. I am proud to have found a new home for my entire team: starting today, Tim Peters, Barry Warsaw, Jeremy Hylton, Fred Drake and myself are working for Digital Creations. We will be spending part of our time on core Python development (including Jython and Mailman) and part of our time on Python infrastructure improvements that also benefit Zope. Python will remain Open Source; Digital Creations has no desire to monetize or brand the Python language or specific Python distributions. All future work we do on Python as Digital Creations employees will be owned by a non-profit organization yet to be created. We think of this new organization as the Python Software Foundation. In the meantime (while the PSF is under construction) I will own such copyrights personally. We're excited to be working for Digital Creations: they are one of the oldest companies active in the Python community, one of the companies most committed to Python, and they have a great product!

[Zope] JOB: Fantastic Zope position at Fortune 100 company
Hello friends. We at Digital Creations have been pretty low-key about promoting job announcements. I'll break the tradition, but only to promote someone else's job position. The reason I'm getting involved is the project is a Big Deal for Zope and the folks involved are great people. For those not interested, please grant me a "get out of jail free" pass on this one. :^) In the very near future, a Fortune 100 media company will launch a new web initiative for which Zope is the content management platform. Digital Creations has been working closely with the company on the architecture for the project. With the initial success, the company wants to augment its internal Zope technical staffing. The job opening is for someone with strong Zope/Python skills, preferably on Linux. Background in web design, information architectures, and project management are beneficial. The vision for this project is quite exciting indeed. If any of you are interested in a prime-time Zope position in New York City, contact me ([EMAIL PROTECTED]) and I'll pass along your contact information.

[Zope-dev] DISCUSS: XHTML Templates proposal
Howdy folks. As advertised in my last email, below is our Fishbowl Proposal on a new template architecture. Some notes: 1) This mostly replaces DTML. As mentioned, the goal isn't necessarily to get DTML removed from Zope. Rather, most of the audience will see it little or none of the time. 2) This proposal has gotten more internal DC scrutiny from a requirements perspective than anything we've done. The proposal has been rewritten four times. 3) The original version of this forced the connection between reinventing the data tier (documents) and the presentation tier (templates/pages/stylesheets). We eventually found the way to decouple the connection, but we still need to write a documents proposal. 4) What this really, really needs right now is extensive user documentation with screenshots written *before* the software. This is where we got stuck. Docs are the fastest way to confront the myriad of usage details. 5) Our proposal is a little more ambitious than HiperDOM (we have a concept of "components" that are hinted to but not explained). But for now, HiperDOM is a good basis for exploring XHTML Templates. 6) I'm still not convinced template is the right word. Unfortunately I'm less convinced at any alternatives. Whatever is chosen, it must feel "normal" to the vast majority of the audience. Cheers! --Paul XHTML Template Architecture Zope should increase usability and promote separation of tiers by moving to a presentation and data architecture. Site Designers will author and round-trip presentation objects in familiar tools. Combined with the Document Architecture, this proposal establishes the fundamental content and presentation architecture for Zope. Note on status The great folks at Hiperglocia have already produced something quite similar to what is discussed here. Their Zope product is called "HiperDOM", http://www.zope.org/Members/lalo/HiperDOM/. Note On Jargon The choice of term for the presentation object has been contentious. Right now the list of choices include: template, view, page, or stylesheet. This proposal doesn't make the decision on the jargon. Rather, the tier is usually refered to as the presentation. When a choice has to be made, such as the Architecture section, Template is used as the temporary choice. Problem Zope currently has a model of DTML Documents and DTML Methods as the basic data and presentation tiers. However, this model is confusing, doesn't promote separation of tiers, and doesn't work with popular web design/authoring tools. For the presentation tier, Site Designers are faced with an idiom in which well-formed HTML is split between two "files" (standard_html_header and standard_html_footer). Also, the presentation mockups are "taken away" by programmers who insert a bunch of alien tags that don't present anything on the screen of the web design tool. Worse, DTML is fundamentally impossible to edit directly by classic tools due to the "source vs. rendered" issue. That is, when a Site Designer wants to edit a piece of DTML, they will get the *rendered* version of the DTML for editing, where all the DTML tags are expanded into HTML. In summary, there is a tremendous usability issue, both conceptual and in practice. There are additional problems: o DTML is considered a "proprietary" language o Data needs to have different presentations used under different conditions o Consulting practices need a way for customers to start seeing screen results immediately without having the programmer "steal" the templates by converting them to something alien Goals The goals of the Presentation Architecture are: o Clear separation of presentation, data, and logic with clear concepts in Zope for these tiers and audiences o Increase usability by allowing round trip presentation with common tools and familiar concepts o Allow those presentation tools to work by having well-formed markup (e.g. no separation into header and footer) o Supplant "proprietary" markup language (DTML) in presentation tier by leveraging standards (XHTML) (Note: "eliminate" isn't the target as it might not be feasible in 100% of the cases) o Match the appropriate level of capability currently in DTML usage o Simple presentation reuse within reach of standard tools Solution Zope should move to an architecture with clear separation of presentation, data, and logic, with clear concepts in Zope for these tiers and audiences. The presentation tier will get a tremendous usability increase by allowing round trip presentation with common tools. This also ensures that Site Designers finish with the same stuff they started with, meaning the programmers don't come in and cast their work into "code". The architecture should make sure those presentation tools are effective by having well-formed markup (e.g. no

RE: [Zope] Is anyone know when Zope was born ???
As far as I'm concerned, Zope was born Saturday, June 8, 1996. This was Jim Fulton's plane trip back from IPC4: http://www.python.org/workshops/1996-06/ Beyond that, Zope (as a unification of previous software) was announced in November 1998 and released in December 1998. DC had some prior art in the field before IPC4, such as my W3C tech note on the "ILU Requester", technology for making web servers talk CORBA to services. Also, Brian Lloyd had, with someone else here at the time, cooked up an early ORB to handle message dispatch from the web into Python. However, our work was tiny compared to Jim's plane trip back. I pick the 1996 date because, well, from a marketing perspective it makes Zope look more mature. :^) But that's the best date. Here's "the rest of the story". Jim joined Digital Creations about a week before IPC4. He had already scheduled to go to IPC4, and I had scheduled to go and teach a CGI class. Instead, I decided to go on vacation and make him teach the class. Slight problem: he had never heard of CGI. So on the plane ride there he read the CGI spec, some background material, and rewrote my presentation. In the process he decided CGI was broken and needed a bunch of things, primarily object orientation. The "python object publisher" (an ORB) was conceived during the conference and was largely written on the plane ride back. The ORB quickly took over our consulting business. Within a year we added a template system, then a persistent object system, then... That's the story. So there, we have a birthdate! --Paul -Original Message- From: Chris Withers [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 30, 2000 5:17 AM To: Frederic Quin Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [Zope] Is anyone know when Zope was born ???

Re: [Zope] Defining High Load in Heavily DB Driven site (was: [Zope] zope2.2.0 and what is high load)
"Dario Lopez-Kästen" wrote: Hello! Hello Dario! I need to find more info on how Zope handles threading with relation to database connections. How about: http://www.zope.org/Documentation/Developer/Models/ZODB The jargon of threads and connections (and then threads again) can be pretty confusing in Zope. First, ZServer is the thing in front listening for socket requests. It has a connection pool (select based) which maps into Python threads in the Zope application. (ZServer is part of the Zope process, I'm discussing logical partitioning.) Each concept of a "thread" in Zope is actually a "database connection" to the ZODB. Threads get a private copy of the transaction space, thus greatly simplifying (to the point of removal) the need for programmers to think about thread safety. If you're talking about the thread concurrency a connection to Oracle, then that's a bit different. I _think_ that ultimately this maps to the number of Zope database connections. This conversation is probably better in the zope-dev list. I am currently considering and evaluating Zope as one of the options we have to build a really large, completely databasedriven "enterprise scale" web-platform. I am a bit worried about this "maximum of 7 threads per db This isn't a maximum. It's just the default. It's easy to increase the number of connections. connection" limitation mentioned previously, and I need to know a) what does this mean in terms of accesibility, b) how does it affect performace, and c) how does Zope work (in detail) with external database connections. We are going to be using Oracle as our DB backend, all our served data will be database *only* (some of it will be fairly large), and efficient database connections is *crucial* to what we intend to do. Since you're not using any persistent objects in Zope (unless you do caching of the SQL data, which you probably should), then you don't have to worry about process growth from having more database connections for Zope. Jack it up to 25. Since much of the time in a Zope hit is taken by rendering to HTML, a number like 25 probably means you can process a hundred simultaneous Oracle requests. That works out to be an average of around ten million hits per day. If you want more, increase the number. We are going to have between 10-20k users at most and I expect the maximun of simultaneous connections to be beween 400 - 900 under heavy load; "normal load" will probably oscillate around 25-200 simultaneous connections (these numbers are crude guesses, but take into account increased usage over time as more services are provided in the future). Bandwith problems are not an issue, nor is computing power. I would appreciate any pointers to documentation or people to ask.

There was tremendous discussion on the mailing list around the time of the introduction of the new syntax. As Jim made clear, the goals of the new syntax did _not_ include XML compliance. Instead, the goals were: a. Get rid of the old syntax. The SSI style was universally ridiculed and requires typing of hard-to-reach characters. b. Make it possible for some HTML editors that can extend their tag database to recognize DTML tags. At the time of the introduction, XML editors were not widely adopted. That still hasn't changed.

I'm pretty sure "new syntax" DTML is not actually valid XML, but it doesn't really matter: it's a bad idea either way. The new syntax is a misguided attempt to mix the base and meta levels, which can only result in confusion. DTML is not markup, it is a macro language for generating markup. As such, it will not always be possible to coerce it into a form that meets the syntax rules of the base language. But meeting those rules, and consequently being able to use XML editors, is the only real justification for the new syntax. h1 !--#if "fervor 2"--class="hot"!--#/if-- How do I do this in "new" DTML? /h1 h1 dtml-if "fervor 2"class="hot"/dtml-if This isn't valid XML (bad attribute). /h1 dtml-if expr="fervor 2" h1 class="hot" dtml-else h1 /dtml-if This isn't valid XML, either (bad nesting). /h1 dtml-if expr="fervor 2" h1 class="hot" This is very clumsy and does not scale. /h1 dtml-else h1 ...but I think it is valid XML. /h1 /dtml-if Also, XML requires all attributes to be quoted, so forget about using the implicit name/expr distinction with your shiny new XML editor. The new syntax doesn't satisfy the arguments that were given to support it, and it decreases the readability and maintainability of DTML code that uses it by making it hard to distinguish DTML directives from markup.

David was going to check to see if the embedded Python could import C extensions. If it could, I know of a little object publishing environment that could run in Mozilla. :^) --Paul -Original Message- From: Martijn Pieters [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 24, 2000 2:42 PM To: David Ascher Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [Zope-Moz] Good news for Zope/Mozilla efforts!

We will be working with Netscape to solve that problem as well, but not in the short term. Nevertheless, I think you'll be pleased to see what can be accomplished with Python and Perl components... Stop it, you have me drooling already! I take it Python will not loose it's ability to import other Python modules.

[Zope] FYI: Latest gem appears in CVS
Howdy folks. As mentioned previously, a gem is ready to appear in CVS: mountable databases. What are these? I'll answer with a question. Ever want to have your data segregated into multiple Data.fs files? Ever want to have some of your object data in the regular FileStorage, some in a Berkeley storage for no undo, some in some mythical forthcoming RelationalStorage, etc.? Or perhaps you want to segregate your data for other reasons. This is mountable databases, and it's running on Zope.org right now. We're doing it to have Wikis that don't get pack, to let us see historical information. If you want to send thanks, send them to Jim Fulton and Shane Hathaway. But how would we see the historical information, since Zope doesn't do CVS-like things? Those of you on zope-checkins might have seen this today: """ Message: 4 Date: Sat, 20 May 2000 12:07:08 -0400 From: Jim Fulton [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [Zope-Checkins] CVS: Zope2 - History.py:1.1 history.dtml:1.1 historyCompare.dtml:1.1 ndiff.py:1.1 DTMLMethod.py:1.45 Update of /cvs-repository/Zope2/lib/python/OFS In directory korak.digicool.com:/projects/users/jim/Historical/lib/python/OFS Modified Files: DTMLMethod.py Added Files: History.py history.dtml historyCompare.dtml ndiff.py Log Message: Added the ability to browse, compare, and revert to historical revisions for DTML methods and documents """ Sure enough, I updated my CVS and saw a "History" tab. Fun stuff, and something that's been a long, long time request from the community. Jim did this in his spare time, so he gets 100% of the credit. --Paul ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
