Ok, here are steps to reproduce: Ingredients: 1 copy of TextIndexNG3, with appropriate files edited for non plone usage. 1 copy of zope, sans plone, cmf. run this on either freebsd or windows. Steps: 1. Add a Zcatalog. 2. Add one ZCTextIndex (say, index on id or title). 3. Add one TextIndexNG3 (index on title or id). Be sure to turn on stemming. 4. Fill up the catalog using find objects. 5. Verify the counts for each index. 6. Restart Zope. 7. Take a second gander at those counts.

[Zope] TextIndexNG (2/3) and Zope2.8
Great sirs/madames
of Zope,
I am
attempting to use TextIndexNG on Zope2.8 (No Plone, No CMF).
TextIndexNG2 has
suddenly stopped working (it was fine on 2.7), and indexes will display 'n/a'
rather than a count.
TextIndexNG3:
When trying to start
zope:

True. Let me

[Zope-dev] RE: Memory Leak Question
Sure thing:
I was mucking around in _Acquisition.c with getattr, findattr, etc,
and I noticed checked to see if my code was leaky.
It was! I then checked just vanilla code, and found the same
leak (only much much smaller).
So here is what I did to make things more visible:
In Wrapper_getattro, I simply added a while loop,
and another call to Wrapper_findattr before the return statement
return Wrapper_findattr(self, oname, NULL, NULL, NULL, 1, 1, 0, 0);.
Loop it 1000 times for some fireworks, 5 times for a more modest
display.
Looping other calls (such as Wrapper_acquire before return
Wrapper_acquire(self, oname, filter, extra, orig, explicit,
containment); in Wrapper_findattr)
does not produce a similar leak.
So. To reproduce:
Edit _Acquisition.c
Function Wrapper_getattro
add
int i = 0;
at the top.
then, if self-obj ... and all that, add:
while (i xyz) {
Wrapper_findattr(self, oname, NULL, NULL, NULL, 1, 1, 0, 0);
i++;
}
where xyz is an integer of your choice.
Simply go to the index_html the root or any other object,
fire up task manager (I produced this bug on windows),
then refresh that page rigorously.
Note that this bug can be reproduced without modifying any code.
The loop simply amplifies the leak, making it easier to spot.
(Or the loop causes huge additional problems I am not aware of.
In any case, doing *something* clever to call Wrapper_findattr more than
once should make the problem easier to spot.)

Could you provide details about why you think there's a leak in the code
(what led you to Wrapper_findattr), and how to reproduce it consistently
on a blank platform (Zope 2.8.4 preferred)?
Maybe open a bug in the collector at

RE: [Zope] Silly question
The name could change easily enough. How about __bobo_always_allow__ Which can either be: None A List of traversable items A method that takes the path, and returns whether or not it is traversable. So for a path p: if p[0] == '_': if p_object.__bobo_always_allow__: if type(p_object.__bobo_always_allow__) is type([]): if p in p_object.__bobo_always_allow__: #allow else: #Do what is normally done for '_' bits. else: if p_object.__bobo_always_allow__(p): #allow else: #Do what is normally done for '_' bits. else: #Do what is normally done for '_' bits. Something vaguely like that. That way you could either specify the exact items that start with '_', or have a method determine it on the fly. This way you would not automatically make all attributes that start with an underscore accessible, and the developer could specify exceptions. -Original Message- From: Chris McDonough [mailto:[EMAIL PROTECTED] Sent: Thursday, June 02, 2005 4:15 PM To: Dan Pozmanter Cc: zope@zope.org Subject: Re: [Zope] Silly question The DWIM of not disallowing traversal of underscore names is useful (because it makes it easy to conventionally mark attrs as private) but it can definitely be a drag if you really do want to publish something that begins with an underscore; this happens a lot when you need to deal with allowing uploads of arbitrary filenames. It might be useful to add something like you propose, except I might take exception to the name isTraversable (everything is traversable, really); maybe just set a magic attr on the object like __allow_underscore_traversal__.

RE: [Zope] Modifying __bases__
Out of curiosity, I've noticed the word evil attached to patching of various and monkey kinds. Not bad, or unwise, but evil, implying a morality associated with the act. What is morally wrong with modifying live objects in a dynamic language to achieve desired functionality? The idea is I want to modify the zope core in a way that survives version to version, yet does not impose a specific use case on all zope users. -Original Message- From: Tino Wildenhain [mailto:[EMAIL PROTECTED] Sent: Friday, May 20, 2005 2:38 PM To: Dan Pozmanter Cc: Andreas Jung; zope@zope.org Subject: RE: [Zope] Modifying __bases__ Am Freitag, den 20.05.2005, 13:48 -0400 schrieb Dan Pozmanter: Well, when I run it, I am able to do the following: class A: pass class B(A): pass b = B() B.__bases__ = () print B.__bases__ Not so on the version that comes with zope.

You cannot modify the class bases like this with extension classes. You can work around that like I did with the history (monkey) patch: http://www.zope.org/Members/tino/PatchHistory/view Otherwise it sounds evil and you failed to show the true motivation with your example above.

So there is only one service then?

Is the server side transformation supported? Why? You first use ZPT to create XML and then an XSLT engine to create HTML. This seems like a slow approach to me. ZPT can generate HTML right away, which is much faster. Unless you already have your content in XML, an XSLT engine is total overkill. 3. Is there any good doc available that describes how to do things you do in ZMI programmatically? Zope 3 does not rely as heavily on the ZMI as Zope 2 and in fact all code is developed on the filesystem, so in this case it might be better for you. 4. Zope 2.7 / 3 ? I think you should go with Zope 3. Several projects have already successfully integrated their Pyton code into Zope 3.

[Zope] Underscoring Inaugural Address
Hello there Zopatistas, In my inaugural post, I should like to enquire about getting to a url like so: http://myzopeserver.something.clever/a/path/to/a/file/named/__init__.py Getting to the object "__init__.py" is difficult (it acts like it doesn't exist.) Is there a way to muck about with getattr, traversal, or something related so that, for a particular kind of object (eg with a particular attribute), Zope ignores the "cannot start with a '_' "rule? I notice that the cvs.zope.org seems to transparently solve this problem, so presumably (if said interface is on a zope instance), this is solvable.
