[Zope-dev] Allowed characters in Zope ids
I recently read RFC 2396 which defines the generic URI syntax and especially the URL syntax. I recognized, that * Zope forbids many characters in ids (with the error message "not allowed in URLs"), that are legal characters in URL path segments: generally allowed in URL's: -_.!~*'() Zope accepted:_. ~ allowed in path segments: :@&=+$, Zope accepted: , This, probably, is not a big problem. But, it would be easy to fix. * Zope allows space characters in (ObjectManager) id's. The space is not a valid URL character. Zope forbids spaces in property ids. * The URL path segment syntax provides for a parameter section suffix where each parameter is introduced with ';'. Future Zope versions should probably take care of this (recent) extension. It might, too, provide a good way to pass values in URLs without the pollution of the query string.

I'm guessing you have installed the latest tarball of the PTK, and
not the CVS version; that tarball shipped with a bug in PortalFolder,
which prevented classes which had not registered as "portal content"
from showing up in its objectItems()/objectValues/objectIds() lists.
Please try upgrading to the latest CVS and see if the problem persists
(http://www.zope.org/Products/PTK/ has directions for getting the CVS
version). Alternately, here is the patch for PTKBase/PortalFolder.py:

My temporary workaround is to have each method assert the appropriate permission, as part of creating its audit trail entry. I plan to arrange for the permission-role mapping computation to be handled by the workflow tool, as well.

[Zope-dev] uncataloging objects
hi there.
i have certain problems with the catalog class. i have something over 9000
objects (all of the same type) cataloged, and it does not only take REAL
long to reindex them (but hey, i could live with that), sometimes it also
makes the python-process sort of 'hang up' - it merly crushes the whole zope
process..
the even bigger problem is that it makes trouble when uncataloging
objectsthat seems to fail completely:
here's some code from the class-definition, where i try to uncatalog the
object:
def killMe(self):
"deletes the record. in fact the record has to be
uncataloged first."
try:
self.Catalog.uncatalog_object('/'+self.absolute_url(1))
except:
return "couldn't uncatalog the record."
try:
self.records.manage_delObjects(ids=self.getId())
# 'records' is a folder, in which the objects are stored
except:
return "couldn't delete the record."
return Globals.MessageDialog(
titel='Record deleted',
message='Record deleted successfully.',
)
so i let my objects kill themselves;)
what really confuses me is the fact that while performing that function, no
exeption is raised. the uncataloging-call is inside a try/except, but it
seems to be performed regulary. but: it isn't!
the object, while already deleted, remains still cataloged, which leads to
some unpleasant error-pages (key-error) when contained inside the result-set
of a search.
i have a zope 2.2.2 under linux installed, with hotfixes 2000-10-02,
2000-10-11, 2000-12-08, 2000-12-15a and 2000-12-18, zcatalog 2.2.0 and some
selfwritten stuff
does anybody have an idea what goes wrong here?

Re: [Zope-dev] Conflict Errors
Y'know since replying to this message originally, I've learned a lot about
pickled representations of Zope objects and I think I can answer this more
cogently:
- Instances of classes which inherit from Persistence.Persistent are
represented as an individual pickle. Their attributes are contained in this
pickle, unless those attributes are themselves instances of something that
inherits from Persistence.Persistent.
- References to persistent objects in other objects are kept as an object
identifier. This means, for example, that a dictionary of integers to
persistent object instances looks something like this in a pickle::
{1:<>, 2:<>, ...}
If this dictionary is an attribute of a persistent object, adding,
changing, or removing items from it will modify its containing persistent
object.
It was this "reference by oid" concept that turned the light on for me here,
hopefully it can do the same for you.
One of the potential big wins with the current Zope implementation of a
BTree is that it exposes a mapping interface, so you can treat it just like
a dictionary. However, internally, it's composed of a number of separate
persistent objects that can be changed independently of each other. This
means that changing one item in a BTree will change one persistent object
that makes up a BTree, but will not necessarily effect the other persistent
objects that compose it. Unortunately, currently, the BTree implementation
has some problems that cause that *not* to be the case in many situations,
and independent writes to it often conflict. We are working on another
BTree implementation to resolve the issue.

I have no idea what might have happened. That's why I'm wary: if something goes wrong, the symptoms will show up a long time after the problems occur.

Re: [Zope-dev] What's 'section' in blocks[0] in block dtml tag?
Lee, I've been diddling around with the same stuff. It took me a lot of introspection with printing of errors via MrCreosote/Spew. To answer your question, 'section' is an object which contains an attribute 'blocks'. If you want to render the dtml in there, you can run the 'render_blocks' method in '/lib/Python/pDocumentTemplate.py' You pass it the section.blocks object and a mapping dictionary which is the current namespace stack that gets passed in as the only argument to the 'render' method in you tag definition. If you just want the raw text, check you the render_blocks method, so you can see how they take apart the 'section.blocks' object. As to the object hiarchy of everything, your guess is as good as mine as to why there's a list of tuples of blocks wrapped in a section object, wrapped in another blocks object, I have know idea.

I believe the latest LoginManager allows you to specify what roles a user has, and compute these each request, based on the details of the request. This is probably more useful than having dynamically computed permissions; While I can see how a user's roles will vary according to where they are, what they are doing and when they are doing it, I cannot see why permissions need to change in that way. However, you mention that you are new to Zope. ZPatterns can be difficult to understand and get into. Other than the creators of ZPatterns, I haven't heard of anyone using this computed permissions system. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ 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 think the point was missed slightly in the discussion. Right now containers can limit what kinds of objects they can contain. It should also be possible for objects to limit what kinds of containers can contain them.

Your script uses an attribute (doerID) in the WITH clause that is provided
by the COMPUTE clause. This is infinitely recursive in theory. In
practice, it will result in the non-existence of the doerID attribute, as
ZPatterns treats recursive attribute references as non-existence of the
attribute. The WITH clause will fail with an AttributeError.

[Zope-dev] "dynamic permissions" in zope
Hi, I'm very new to zope and have to eximine, if it's usable for our requirements. The question I have, is very simple or perhaps very difficult, I don't know. Our requrements are a permissioning system which depends on a matrix: There are two independend qualities which describe, if a user is allowed to see a document. This can be displayed in a matrix. Only if *both* qualities match, the user is allowed to see it. As far as I understand zope, it is not possible to map this directly (as by all other systems I know). So my question: Is it possible to connect a permission (or role) in zope with a method (instead of a static flag which was set)? If it is possible, it should be possible to call a special algorithm with this request, which can implement whatever is needed. So, it would be (easy) possible to *integrate* this functionality. (I called this permissions "dynamic", because the are evaluated when requestet.) Or does anybody has another (better) idea?

[Zope-dev] aq_inContextOf attribute error
Hello All !
After installing latest stable version of Zope (2.2.4) I tried to
install ZFormulator version 0.2. And as result got 2 problems with
permissions system. First was in ZFormulator itself, and was corrected:
__roles__ = ('manager',)
was changed to
__roles__ = ('Manager',)
but this bug correction worked fine for previous versions of Zope,
and in current version adding of field produced error:
Attribute Error: aq_inContextOf in line 231 of
lib/python/AccessControl/User.py
I am nor Zope nor Python hacker, but I tried to correct this line a little,
and this worked for me. Please advice did I made it correct way or not.
User.py line 231:
Here was the original code (which produced error):
if not parent.aq_inContextOf(self.aq_parent.aq_parent,1):
Here is replacement (added check is attribute exists):
if hasattr(parent, 'aq_inContextOf') and not
parent.aq_inContextOf(self.aq_parent.aq_parent,1):
After this correction everything works fine, but since I am not Zope/Python
guru, but just a user which wanted some program to start working, I keeping
changed locally, but of course I am interested was this correction OK.
Regards.
