[Zope-dev] Survey on Open Source
Dear all, I am conducting a survey on open source software. This is for my academic coursework and dissertation. It will be great to have your support and participation in this survey. This survey has two separate questionnaires, focusing on the following areas: 1) OSS development (Developers or those who contribute in coding or documentation), and 2) IT/IS costs (CIOs or IT Managers). You are free to go for the questionnaire that is appropriate for you. Below are the links: 1) Brief introduction page: http://web.singnet.com.sg/~mikecck/opensource/Introduction1.htm 2) Questionnaire 1(Open Source Development): http://web.singnet.com.sg/~mikecck/opensource/WebFormA1.htm 3) Questionnaire 2(Open Source and IT/IS Cost): http://web.singnet.com.sg/~mikecck/opensource/WebFormB1.htm Thank you for your time.

[Zope-dev] New-style classes and ClassSecurityInfo, fixed already?
http://zope.org/Collectors/Zope/1055 Is a bug report I filed a while ago for a fairly trivial breakage of the ClassSecurityInfo class due to the use of assignment to the class dictionary during the apply method. I'm wondering, is this fixed now on CVS head? I've been using a work-around module sub-class for Zope 2.7 work w/ new-style classes, but I can't imagine that's something that would be wanted as a solution. The ClassSecurityInfo.apply method is changed to use setattr instead of dict['x'] = y. The InitializeClass function also needs to have the same transformation applied to it. If desired I can pull the CVS tree and produce a diff if the problem isn't already solved. Have fun, Mike ___ Mike C.

AFAICT, AdaptableStorage is designed to allow this kind of thing. Shane? Sounds interesting. I am going to search for this. Yes, it is. I don't know anything about NetCDF, but it sounds intriguing.

[Zope-dev] html version of zope site
Hi! First of all: We have a client that (because of lame internal policy) will not be able to install zope on the final server. However, they _do_ want zope as a publishing solution for a web that will be practically nothing but dtml docs, images, and folders. They're only intested in accessing the web interface to modify text in custom zclass product interfaces we will make for them. Provided that there are no complicated methods integrated into the zope structure, is it possible to generate a navegable static html version of a zope hierarchy? Our idea is to let them access our server to manage and edit content and to give them a publish option (written in python or perl) that generates the html and ftps the site to a remote, non-zope webserver. The day that the client wants a more dynamic site with searching and such, we would discuss installing zope again on the remote server. Please give me your thoughts on this workaround solution. thanks, -- [[EMAIL PROTECTED] chikoon]$ whoami Mike Blake ___ 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 )

By the way, I do not like this Rack list at all. Racks and Specialists are both DataManagers with compatible interfaces (getItem, newItem). IMHO, Specialists should have list of DataManagers. This make much sense in context of combining Specialists - ZSession and ClientManager, for example. It is not sufficient just to tune ZSession using ClientManager's rack and ZClass, because in this case we are losing the ClientManager's aspect in sessions. Of course, one always can create delegating rack (and even rack-to-specialist bridge), but what do this for if simple replacing rackList with dataManagerList will solve all such problems?

Now that I've had a chance to really look at this (while tracking down one of the bugs you found), I do have a few comments. First, nice job... It's a good adaptation use of ZPatterns. I do have Thanks. some suggestions for fine tuning, though. * Rather than putting property manipulation functions right into the base Session class, I would simply let users derive ZClasses of their own from Session. They could then actually give the Session a UI of its own, for I put those get/set/has stuff just for make easier life of some lazy people (like me :-) example. Think of someone creating a Session subclass called "Shopping Cart", with methods for viewing, checking out, adding/deleting items, etc. Or, if they have many subsystems which want to share the same Session objects, they could do this by having each subsystem use a different propertysheet of the same Session object. Well, well, well. As for me, beter I've set up a Client abstraction which have access to CartManager and store cart_id in the session object. Mixing Session and Cart is not a good idea just because Client can have several carts, for example. The composition is better than inheritance in this case, Phillip :-) IMHO, the basicSheet stuff you've done, while convenient, encourages developers to take the quick-and-dirty route of just using the Session as a place to store variables - and that throws away a lot of the usefulness of ZPatterns. For one thing, you've guaranteed that Sessions have to be stored as persistent objects in the ZODB, or at least that the basicSheet has to support arbitrary properties. But without this stuff people will have to code ZClasses each time they want sessions. Hmm... I guess the best way is splitting current session class into two - simple Session and LazySession. * Make dead session removal something that doesn't happen automatically, or at least have an option to do so. Your default deletion algorithm would be very expensive when executed against a non-ZODB database, and would be more efficiently done a few times a day in large batches by a cron job. Moreover, I found a bug which causes infinite loop :-( You're right, automatic removal should be optional. Will be fixed in 0.0.3 release. * Delegate determining which sessions are dead to the Rack, rather than doing it in the Specialist. This allows an SQL implementation to make use of indexes. Specifically, make removeDead call: self._getSource().findIdleSessions(self.session_ttl) And then provide a default implementation of findIdleSessions() in the Specialist. (Btw, please note that your current implementation absolutely requires that at least *some* session data be stored persistently in the ZODB, which if you're using a FileStorage, is a bad place for it to be.) Now, the whole thing works the same way when first installed, but if someone implements the session ID and lastAccessed attributes in an SQL database, they can substitute a different implementation for findIdleSessions() by putting it in the Rack. Agree with you completely.

Re: [Zope-dev] Externalize or Adapt? (ZPatterns)
Mike wrote: I will add a "retrieveItem" method to the Specialist which, instead of accessing a rack in the local specialist (the default implementation), it will instead call (for example) SkyDivers.getItem(). Thus, when you call Customers.getItem(), you will actually get an object from the SkyDivers specialist. In other words, I make the horizontal domain specialist delegate to the vertical specialist. Maybe the best way is to put a 'thumb' data source into Customers instead of native one. This thumb should translate all messages to SkyDivers' data source. I'm just considering on specialized racks which implement non-standard api, such as 'findItem( criteria)', 'itemValues()' or something similar.
