Indeed :-)
class MyClass (Acquisition.Explicit):
acquisition = ClassAcquisitionInfo()
acquisition.acquire('index_html')
acquisition.acquire('fred')
You already can do that, though with a different syntax
(I would need to search for in the documentation).
You may mean that if x is an Acquisition.Explicit object, you can do:
x.aq_acquire('your_attribute') (syntax may be wrong ;-)
What I meant is that through a declaration in the class you could saying
acquire the 'your_attribute' attribute but nothing else. So, you could
still do:
x.your_attribute ...which would be acquired, but...
x.index_html ...which wouldn't be acquired.

[Zope-dev] ZPatterns; possible bug?
I have a specialist "Instructors".
It holds a rack, containing DataSkin-derived ZClasses of meta-type
"Instructor".
The Instructor class has a DataSkin Attribute propertysheet called
"Basic", and this has properties for forename, surname, address, areas.
I have some skinscript in the Instructors specialist:
WITH SELF COMPUTE
name='%s %s' % (forename, surname),
areas_comma_sep=_.string.join(areas, ','),
address_lines=_.string.join(address, '\n'),
address_comma_sep=_.string.join(address, (', '))
WITH SELF COMPUTE
__roles__=_.None
# XXX publicly visible!! Nutter!!
# change __roles__ to ('Operator',) later.
This works fine. The __roles__ bit is a hack to make Zope 2.3 ZCatalog
play nicely with the Specialist and __bobo_traverse__.
I have some other skinscript that keeps an instructors index in a
ZCatalog inside Instructors.
WHEN OBJECT ADDED CALL
Catalog.catalog_object(self, _.string.join(self.getPhysicalPath(),'/'))
WHEN OBJECT DELETED CALL
Catalog.uncatalog_object(_.string.join(self.getPhysicalPath(),'/'))
WHEN OBJECT CHANGED CALL
Catalog.uncatalog_object(_.string.join(self.getPhysicalPath(),'/')),
Catalog.catalog_object(self, _.string.join(self.getPhysicalPath(),'/'))
This worked fine.
When I changed the first skinscript to make one WITH SELF statement, I
got some strange inconsistencies:
WITH SELF COMPUTE
name='%s %s' % (forename, surname),
areas_comma_sep=_.string.join(areas, ','),
address_lines=_.string.join(address, '\n'),
address_comma_sep=_.string.join(address, (', ')),
__roles__=_.None
On changing an instructor's properties using manage_changeProperties on
its propertysheet, I'd see the change in the instructor. However, the
ZCatalog metadata would always have the most recent value for "surname",
but the last value for "name".
Changing the skinscript back to using two statements makes cataloging
function normally again.
I could tell when the catalog was doing by instrumenting the recordify
method of Catalog.py:
def recordify(self, object):
""" turns an object into a record tuple """
print "recordify %s" % (object)
record = []
# the unique id is allways the first element
for x in self.names:
try:
attr = getattr(object, x)
if(callable(attr)):
attr = attr()
except:
attr = MV
print " appending %s:%s" % (x, attr)
record.append(attr)
return tuple(record)
A typical (wrong) debug output would be:
recordify Instructor instance at 86c16b0
appending id:instructor-977678608
appending meta_type:Instructor
appending bobobase_modification_time:2001/01/04 17:26:01.35408 GMT
appending name:Bob Collins8
appending surname:Collins9
appending areas_comma_sep:M12
This is after changing the surname of the instructor from "Collins8" to
"Collins9".
The cause of the problem? I don't know. Maybe I'm doing something silly.
I think what is happening in the broken example is that when the zope
security machinery asks for __roles__, name is also computed. The
machinery must request __roles__ before changing anything.
After that, surname gets changed. However, changing "surname" only
invalidates "surname" in the cache; not anything that is computed using
surname.
At the end of the transaction, when the triggers are called, name is
already in the dataskin's attribute cache, so it does not get recomputed.
In the working example, when __roles__ is requested, it is in a
different skinscript statement, so it does not cause "name" to be
computed. Thus, "name" can be computed freshly after "surname" is set.
Is this behaviour intended, is it a bug, or is it an unimplemented feature?
Thanks.

[Zope-dev] Re: [Zope] Lobbying (was: [Zope] html_quote in python methods?)
From: Chris Withers [EMAIL PROTECTED]
Only if you add security declarations to expose functionality from
xmlrpclib.
Is that hacky and nasty? :-S
In Zope 2.3, you place the following code somewhere that it will get
executed at startup (a custom Product's __init__ is the best bet):
from AccessControl import ModuleSecurityInfo
security = ModuleSecurityInfo('xmlrpclib')
security.declarePublic('Server')
# or security.setDefaultAccess(1), if you feel lucky.

Re: [Zope-dev] case insensitive sorts
Chris Withers writes: Dieter Maurer wrote: Chris Withers writes: Andrew bart David sophie Wayne Why in hell do you switch caseness for similar objects? Who said anything about objects? Maybe, I should have said subjects. Your example strings seem to name persons. It is very strange (and should be punished, as it is by Python's default sort ;-)) to use caseness inconsistently for these same type subjects/objects/entities (whatever you like). I am not against an option to specify what comparison function should be used for sorting (when I would implement it, I would probably follow Python's sort interface and provide an optional function rather than have a collection of attributes specifying the sort order). However, I am against a change of the sort order in the *management interface* (unless I can easily switch back). The reason: I make sensible use of the ASCII based sort order and would not like to loose it.

I wonder whether the product's version.txt might have something to do with it. Remove version.txt and see if it has any effect. Then try creating a new version.txt. Another thing to watch out for is file permissions. "chmod -R 777 productname" and see if there's any difference. Are you running Zope in "-D" debug mode and watching the output? I can't imagine debugging products in normal mode. Note, however, that Zope 2.1.7 and before don't even show anything in the terminal window when a product has syntax errors.

[Zope-dev] Hacking Splitter.c
Hello, I have been hard at work implementing version 2.0 of our Zope based CRM software. I need a bit of help figuring out Splitter.c (lib/python/SearchIndex/Splitter.c) I have commented out both the parts that don't index numbers and single letter words. The numbers seem to be indexing fine, but the single letter words are not. :( My goal is to be able to find 'C' and 'C++' in a TextIndex search. Can anyone tell me why '+' doesn't get indexed, and where to change that? 'C' isn't in the Lexicon stop words, and neither is the '+'. Thanks in advance.

Re: [Zope-dev] CatalogAware
Erik Enge wrote: [Michael Bernstein] | When called, they find the nearest (acquisition-wise) ZCatalog | (named Catalog by default), I think you can specify the ZCatalog it should index itself in by putting the default_catalog attribute in your class. Your example is correct as far as it goes, but as I understand it, you are not really specifying the default catalog per se, but the default catalog *name*. Therefore, it will then look for the nearest catalog of the name that you have redefined as the default. So if you redefine it to be ZCatalog1, and you have the following structure: / |-/Catalog | |-/ZCatalog1 | |-/folder1 | | | |-/folder1/ZCatalog1 | |-/folder2 Assuming a CatalogAware ZClass has had it's default_catalog defined to be 'ZCatalog1', and that an instance of this ZClass is then added in /folder2, it will index itself in /ZCatalog1, whereas an instance that is added in /folder1 will index itself in /folder1/ZCatalog1. This is my current understanding, I apologise if what I've said is incorrect.

Re: [Zope-dev] ghost product
If you set the environment variable STUPID_LOG_FILE to a file path before starting Zope, you will be able to capture the debug output from the product import procedure in that file.

[Zope-dev] Python Scripts update
Python Scripts have gone through a fair number of changes and bugfixes recently. They should now work properly as methods of ZClasses. When you download the source of a Python Script, the title, parameter list, and bindings are added to the source in the form of specially formatted comments. If source with these comments is uploaded or pasted into a Python Script, it will properly set the properties mentioned in the comment block. The default bindings have been changed to be more sensible. If you want to give Python Scripts a try, you can go to http://ps.4-am.com:9000/ , pick a password, and you'll get your own private area in a trunk CVS checkout of Zope in which to play. I promised examples when I first announced this site, and haven't gotten around to writing any. If you have created a script or set of objects on the demo site that you would like to share as an example, please mail me the URL.
