Thanks, I always forget the flexibility of ZCatalog :-) That said, how hard would it be to alter ZCatalog so you could override the comparison function it uses? It feels like a ,cmp=cmp argument to the added search index consructor, then a self._cmp = cmp in the constructor, followed by a query and replace on cmp with self._cmp in the search index source.

"most humeans" does *not* map to "English speakers who prefer case-insensitive collation." Case-flattening is a lossy operation; there is *no way* you are going to get it by default. If you want the catalog to do a case-insensitive search / sort, then create a method on your object which does the approprate case-flattening, and index that instead of the "real" attribute.

There is no practical difference, unless you are "federating"
queries across multiple catalogs; the 'used' parameter is there
solely to accumulate a record of the indices used in the search.
> (Are used supposed to be a tuple?)
It should be something supporting the mapping interface. Here is
how it is used (from 'lib/python/Products/ZCatalog/Catalog.py'):
if used is None: used={}
for i in self.indexes.keys():
try:
index = self.indexes[i].__of__(self)
if hasattr(index,'_apply_index'):
r=index._apply_index(args)
if r is not None:
r, u = r
for name in u:
used[name]=1
In other words, "Nothing to see here; move along." :)

[Zope-dev] Java and Zope
Hi all, Over the last few weeks there have been a few questions asked as to whether Zope can play with Java or not. Until now the answer has been a resounding 'NO'. Until now that is, I've done some rudimentary tests, NT4 + Zope2.3.0 + JDK1.3, that indicate to the contrary. If you're interested take a look at http://media-1.ml.uwcm.ac.uk:12380/index_html. This page is calling an external method that imports (in the Python sense) the java.lang.String module, and then does a dir() on that module. Theere are still some issues to iron out, the JVM needs to be created on the python thread that is currently executing, this sometimes goes awry and the jvm is not available for the current thread. This is my focus at the moment. Nothing earth shattering right now, but things will get more interesting. Thing is I'm in no way a Java bod, and can't really test this properly, anyone up for testing it? I have the stuff you need, win32 binaries etc, if you want to play Java + Zope stuff.

Damn, where's this documented?
I think this is _exactly_ what I've been looking for for ages, especially, I'm
guessing, that if you don't specify 'used' then:
1. It's assumed all indexes take part in the search
2. All parameters that aren't supplied are assumed to be blank, and therefore
will match anything?
Am I on the right track?
Furthermore, is there any way I can tell ZCatalog that nothing means nothing,
not everything?
For example, if I do searchResults(age=''), I want only records with a blank age
record, _not_ all the records.
Okay while I'm here, one final one.
We have the sort_on and sort_order parameters, they'll return stuff ordered
like:
Aardvark
Badger
anteater
bird
Whereas most humans would think the following would be more readable:
Aardvark
anteater
Badger
bird
I guess ZCatalog uses cmp somewhere along the line. IS there any way I can pass
in a different cmp function for a given index?
Hah, just thought of one last one ;-)
Okay, we have sort_on, which lets me sort on one index. Is there any way I can
provide a secondary sort key?
something like
searchResults(age='',sort_on=(('lastname','normal'),('firstname','normal'),'('salary','reverse')))
would eb a dream.
Wow, that turned into a ZCatalog wishlist... any ideas if any of it is
available, and if not, hwo hard it would be to achieve?
cheers,
Chris

[Zope-dev] Bugs in Zope Membership Component 0.8.0b1
Hi Bill, All PythonScripts in ZMC 0.8.0b1 look like a direct port from Python Methods, so I found some bugs due to the incompatibility between these two version of scripts. 1. In 'passwordForm', 'import string' should be added. 2. In 'passwordPolicy', 'self' should be ommited in the parameters list. 3. 'register', I think, should be proxy to 'Manager', like the original version. There's another bug: anonymous user can access account's manageMe method! Say if there's an account 'dummy', anyone can open 'www.dumy.com/test/acl_users/dummy/manageMe'. I think the permission to view 'manageMe' should be hooked up to that of viewing management screen. I see that you have made some special arrangements in the 'Define Permission' tab of 'Portal Member' ZClass definition, but that doesn't seem to protect its instance, which is a puzzle to me: what's the use to define permissions in ZClass definition or products?

To get company_address stored, you can probably do something like: your_object.manage_changeProperties(company_address=your_object.company_address) or possibly your_object.propertysheets.NameOfSheet.manage_changeProperties... depending on what kind of object you're using. You could have this as a trigger: WHEN OBJECT ADDED CALL self.manage_changeProperties(company_address=self.company_address) As for whether it is a bug, the implementation of the INITALIZE clause just puts its attributes directly into the DataSkin's attribute-cache. It appears to be designed for the behaviour that you see. You could get the behaviour that you want by making the implementation actually set the attributes instead. I'm not sure what the other implications of doing that are, though.

Thanks, but it's got nothing to do with getId... I just used id because it's easy to write. I get the same behavior if I try to view meta_type, or a property that is defined on a propertysheet in the ZClass. And the fact that the DTML Document uses its own attributes shouldn't cause Unauthorized, should it? It should just show a different attribute, or acquire the attribute if it doesn't have it. I just tried it again with a clean install of Zope 2.3.0. In a DTML Document, this works (name is a property in the ZClass propertysheet): But these fail with Unauthorized: , . The in standard_html_header fails as well. I also repeated the folder test: In a DTML Method stored inside a folder in the ZClass, works, but fails. So what do we have? I can't use title_or_id on DTML Documents, so it's useless for use in standard_html_header (and title_or_id uses getId, so it should work). I can't access ZClass properties from the DTML Document unless I use dtml-with - meaning no acquisition. And I can't access properties of the DTML Document (like meta_type) unless they are accessed using a method call (like getId()). This can't be right. I find it hard to believe that if this is really a bug, it didn't bother anybody else until now. On the other hand, these tests seem to show a problem with security checks on objects in ZClasses that create their own context. So what am I still missing here?

I guess it would be better to allow constructs as:
Some text
Where 'table' and 'font' are PythonScripts that return the implicit blocks passed to
them (these blocks may have a default variable name in the expression's namespaces)
enclosed by the correspondent html blocks, with the format ('main, 'standard') mapped
to html attributes/values using some dictionaries. This could help to separate logic
and presentation in dtml code with a minor syntax addition.

'getObject' forces you to "wake up" the catalogued object;
in a large enough result set, the price is pretty punitive,
compared to serving the results as cached metadata.

Re: [Zope-dev] Storing part of an object on the file system
Actually just follow up I realised I never told you how I solved this problem. I compacted all data types into File, Image or DTML Document. Since I had ExtFile and ExtImage I chopped those into one class called it ExtThing, and the wrote classes off it. ExtFile and ExtImage I cut and pasted (not complete) for the most part. Then I wrote a class that called ExtHTML that is a DTML Document that overrides the munge() and read() read functions. Instead I passed those onto ExtThing. And there you go a DTML Document that has the main body stored on the local file system.

Well, that cleared it up, didn't it? :). (Prolly missing a "that"?) Another thing, which might be a bug or a feature. I used to do REQUEST.form.keys() to list all attributes in the REQUEST. With 2.3.1b1 that doesn't seem to work, because the attributes are in REQUEST.other. (This is when posting from a form.) The words REQUEST and RESPONSE are also in other, so when I want to do stuff with it I need to make sure I don't include those in the REQUEST which I'm shipping off (because then they would only be strings, not instances, to the next method). ___ 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 )

I guess it would be better to allow constructs as:
Some text
Where 'table' and 'font' are PythonScripts that return the implicit blocks passed to
them (these blocks may have a default variable name in the expression's namespaces)
enclosed by the correspondent html blocks, with the format ('main, 'standard') mapped
to html attributes/values using some dictionaries. This could help to separate logic
and presentation in dtml code with a minor syntax addition.
