Re: Security internals, was Re: [Zope-dev] LOTS of roles?
hm... i could have told you that the LDAPUser class in the LDAPUserFolder product can do that but i had the whole thread mostly tuned out. initially it did not look like anything i could help with and the first posting was very long if i remember correctly. jens On Thursday, Mar 6, 2003, at 17:13 US/Eastern, Paul Winkler wrote: On Fri, Mar 07, 2003 at 08:56:59AM +1100, Adrian van den Dries wrote: (/me revisits LDAPUserFolder) Looks like the work is already done for you anyway: allowed() and friends check if the context has an attribute acl_satellite, and queries it for any additional roles, and it even keeps a cache. !!

[Zope-dev] ZODB: Are all handles closed?
Hello list, in our product (and additionally in an other process) we use separate ZODB-Storages. Opening and closing the ZODB several times the number of file-handles increases. We have separated the multiple openings and closings to the following code. It shows the increasing of the handles clearly. Have we forgotten to clear anything or made anything wrong? If not, has anybody an idea, how to fix or work around the problem. --snip--snap- from ZODB import FileStorage, DB for i in range (1,100): storage=FileStorage.FileStorage(TestZODB.fs) db = DB(storage) db.open() print Open db.close() print Close storage.close() --snip--snap- Enother nice behaviour we can achieve with the following code: --snip--snap- from ZODB import FileStorage, DB storage=FileStorage.FileStorage(TestZODB.fs) db = DB(storage) for i in range (1,100): db.open() print Open db.close() print Close storage.close() --snip--snap- It works about seven times. Then the programm hangs completely.

[Zope-dev] implementing structured text alternative w/in Zope
Hi, I'm a programmer but new to Zope. I'm developing a text markup language like Structured Text that better suits my needs outside the Zope/Python world. Would I be able to incorporate it within Zope, i.e., so I could edit the new format in the edit window and have it displayed as HTML by the server, handled as a Zope object, etc.? I'd like to do it as transparently as (on the lowest level) possible, but if it turns out I have to do it as a feature of a product, that will be OK. Any tips for either scenario much appreciated.

Steve Alexander wrote: This is possible. But, the problem remains that both a and b (in your example above) are evaluated. I don't see the problem with that, unless a or b actually do stuff, and modify stuff, and if it does, in ZPT it should then be put into a script, since the template itself shouldn't contain any business logic. I can see the use of a one-line if-else syntax in ZPT as a way to set an attribute without making a specific pythons script just for such a small piece of code, and this will do it. If you want to *DO* different stuff depending on a condition, that shouldn't be in the template. Also, Evan tells me that this already exists in python: expressions, and is called test(). So, problem solved, no additional uglyfication of Python is needed. :) ___ Zope-Dev maillist - [EMAIL PROTECTED] 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 )

Of course you can do that with Zope. You'll find quite a few examples of new markup languages for Zope if you browse the Products list on zope.org. You definitely will have to write a product for this. You need a basic method or document object (like DTMLMethod). Writing or adapting the over-the-web edit screens is simple. The harder part will be the parser that generates the HTML for you. But I guess you know how to do this. There is one thing that might be trickier than you'd expect: If you want to have the same security features as in DTML or ZPT (i.e. checking for every method call and attribute if the viewer has the permissions to execute/view them) you will have to implement much of that on your own in the language parser. Note that if you keep it as simple as structured text you won't need to care about the security issue. In structured text you don't call other code or attributes ... The document object will have to implement a __call__() (or index_html()) method for it. This method has to take the code (that is stored in a property of the object) and render it. Then you just return the result at the end. It's really not that difficult, and if you take a similar product and look at the code it is relatively easy to understand. Be sure that you read the Zope Developers Guide on zope.org first!

Remember that in the grand scheme of things, most everything in Zope is a Product. And practically everything can be manipulated by a product. Especially with what you intend to do: not too long ago was ZPT an add-on product, as well as STX. DTML and ZSQLMethods are implemented as products. So you're not really losing anything by doing it that way. If what you're doing is really useful and general, perhaps it will be added to the Zope distribution sometime in the future, but you needn't count on that.' --jcc ___ Zope-Dev maillist - [EMAIL PROTECTED] 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 )
