[Zope-dev] Adding execute() to Zope DA's for use by External methods
I have Python code that I use outside of Zope, and inside Zope via external methods. This code uses database adapters (anything version 1 or later). When my code is used within Zope, I have in the past had two database connections from within the Zope process. One connection is the actual Zope DA (I'm using gvib) and the other is a python db connection. This has worked okay on Windows, but I'm getting strange lockup problems after moving to Linux. In any case, it seems to me the better way to do this would be to allow external methods to get db-like access to a zope DA. Most Zope DA's are built in db-sig type db connectors, so it seems like a relatively simple matter to define a new interface for Zope DA's to make available that supports execute semantics. The big issue in my mind is determining what kind of security needs to be applied to such a function, and how that security would be implemented. I suppose stealing roles/rights from SQL_Methods for use here makes sense. If you can call an SQL method, you can call execute() directly. Is there any support from the Zope community to add execute() like operations to Zope DA's? If yes, where should I start in figuring out security for this. And finally, how does an external method pass security information "back" to the DA? For example, I tried passing my Gvib instance to an external method. But when that method called the gvib instance to get a connection instance, it got a "no __call__ method" error. So then I tried passing the connection from dtml, ie dtml-var "MyMethod(db=MyInterbaseConnection())" but when MyMethod calls db.cursor() it gets a security error. Probably because this function isn't exposed by the security machinery. (same thing probably for the __call__ error) Brad Clements,[EMAIL PROTECTED] (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com AOL-IM: BKClements ___ 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] License issues
Juan, thanks for shining some light towards this murky area. Maybe ZWiki and other zope products need to be LGPL or dual-licensed, maybe the zope license can use some refinement. I for one won't know without seeing some enlightened discussion of the issue. This stuff is unsexy but important.

[Zope-dev] Two glaring omissions
Hi, I've been working with Zope for almost two years now, and there are two things that I feel is missing in the interface: 1. The ability to add a Base class after the class is created 2. The ability to rename properties after instances of the classes have been created (and have the data in those fields preserved) Are there any technical reasons why these are not present? I know it is possible to add base classes in retrospect via the hack described in http://www.zope.org/Members/AlexR/ChangingBaseClasses but are there plans for making this easier? As for #2, it is quite annoying and counter-productive not being able to change a variable name that was decided a long time ago, or maybe by others simply because there exist instantiated objects of that type. Both of the above are pretty essential OO techniques (for me, at least), and hinder my work quite a lot by not being there. Any chance of these being fixed at all? Or are there reasons that I do not know about that makes this impossible?

The ability to add a Base class after the class is created This is a feature we'd like to have, but the way ZClasses work currently makes it dangerous. What gets pickled in the ZODB isn't information about the class, it's the class itself. In order to change bases safely, you'd have to try to reverse-engineer the original parameters for creating the class object as well as all changes made afterward, then modify the parameters slightly and construct a new class. That's what the published hack essentially does. Another pitfall of storing the class itself in the ZODB is that if any of the bases disappear, the ZClass can no longer be loaded. If these two issues are important enough, we have a good reason to consider a new kind of ZClass. With "lightweight" ZClasses, class data would be stored in a meta-class object. The meta-class would construct the class instance. Changes bases and failing gracefully when a base disappears should be easy. The part that may still be hard is getting object instances to sync up with the ZClass immediately when the user has changed the ZClass. ZClasses are good at that, you see. 2. The ability to rename properties after instances of the classes have been created (and have the data in those fields preserved) This is also more difficult than it sounds. You'd have to either scan through the entire ZODB and modify class instances or associate properties with a magical, unchanging ID. The latter solution is dead wrong, but the first is actually kind of interesting. If there were a separate index for each object type in the ZODB, it would be possible. In fact, when ZODB is running from a relational database, there is indeed a way to do that. Hmmm... Not that I have the time to work on these things. I'm swamped. Anyone want to draft a proposal?

Re: [Zope-dev] PythonMethods: Can't Slice context.REQUEST.PARENTS
The Doctor What writes: Using context.this().id, self.this().id, m_self.this().id all get me the same things: Folder, Zope, and my method. None give me the DTML Document foo_html. If it is indeed a DTML Document, then "this()" should reference this document. If it is a DTML Method, then "this()" will reference the methods 'client', usually the methods parent. Did you mean to do a this().id? That doesn't work at all, it gives me a Name Error. No. I am not yet familiar with PythonMethods and what binding they define automatically. Obviously, you have "context", "m_self" and "self". My older PythonMethods installed seem to support only "self", but I am not sure. I would expect, that "context.this()" has the highest chance of success, maybe "self.this()". Note, that "foo_html" must be a DTML Document not a DTML Method! There *must* be a way to do this. There is none for DTML Methods (other than modifying the code).

Re: [Zope-dev] PythonMethods: Can't Slice context.REQUEST.PARENTS
I got a reply from someone working on it. It seems the answer is that it doesn't exist yet, pending a change in ZOPE itself. So I have to pass it in: dtml-var expr="breadcrumbs(this())" Not a big deal, but annoying. I'll make the source available as soon as I coble together a view-source method. :) Ciao! -- "Well, given that the universe is infinite, and that God is infinite, and that God created the universe, (pause) would you like a piece of toast?" --Talkie Toaster (Red Dwarf episode: Dimension Jump) The Doctor What: A Holtje Production http://docwhat.gerf.org/ [EMAIL PROTECTED] KF6VNC ___ 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 )

None give me the DTML Document foo_html. This would seem to be an important thing. The only information about your caller that you can get is the contents of their namespace. So, in the final release, you would be able to bind the caller's namespace to "_" and write _.this().id. That requires a change to Zope, though, so it doesn't work yet. You *could* work around this by explicitly passing the namespace (or this(), for that matter). Why can't I get the acquisition context as with External Methods? (if they are called directly via the Web, namespaces are not yet build and the acquisition context obtained via a "self" parameter is everything I have).
