 first beta for 2.9 and 3.2 on 1 November.  Even if we don't branch at

Yeah, but the bug day was a big flop for both Zope 2 and Zope 3, so Andreas 
and I (and even with Jim's approval) decided not to release. I also will not 
cut a branch until more bugs have been fixed, so that I lower the bar for bug 
fixers and force people to work on bugs not features.

BTW, I think that Philipp did the right thing. Depending on a specific 
revision is fine, though pointing to the trunk right now would work too, 
since it is feature frozen.

Hi Mikhail,

the outline is nice, but contains items that we do not have already; for

this type of documentation exists and you cannot expect it to magically

Having said this, I really wish someone would take ownership in developing our

With that much interest I would hope that a steady developer group around

 this is a problem i think for automated tests etc.

This is a problem. It would be easier if you add a sample configuration file 
in your test directory, e.g. cxoracle/tests/configfile.py and then reference 
it as follows in your test:

  import os
  dir = os.path.dirname(__file__)
  config = os.path.join(dir, 'configfile.py')

 The drawback*) of this is that the adapter registry has to be in place.

No it does not need to necessarily, because the __conform__ method is called
before a standard adapter lookup is made. Also, for those type of scenarios
we could have a custom adapter registry. Luckily adapter registries are
implemented in zope.interface.adapter, so no external packages would be

Your fix below is definitely unacceptable, because it fixes the issue and the

No, it wouldn't.  In my strongly held opinion, you should never
depend on a trunk or branch unless the people checking in there
are running *your* tests before a checkin.  A bug fix I made earlier
this week actually broke a Five test.

Depending on revisions, which you update frequently, provides important
stability.  The person who updates the revision can first make sure
all their tests pass, addressing any issues before checking in.

Am Freitag, 11. November 2005 18:00 schrieb Jean-Marc Orliaguet:

  

I was thinking more about the policy of assigning unique ids
to objects in a relation. It's the application that really
should decide about that policy.



in fact the unique ids aren't assigned to the objects (the 
objects aren't touched at all) by the IntIds utility - if you 
have registered a local IntIds utility they are just created in 
the utility driven by the IObjectAdded event. So this IntIds 
stuff should not interfere with anything else and the 
application should not be concerned at all about it.
  


The good thing about IntIds is that it leaves the objects untouched, the
bad thing is that it creates a hard coupling between the integer id that
is used to *refer* to the object and the key that is used to *represent*
the object in the relation. These are really two different aspects.

In cpsskins when objects are set in relation, it is the application's
responsibility to tell the engine how objects will be identified in the
relation, i.e. with a unique id (IntIds), or with a URI or a with a name
(that may be share between several objects) ... The relation engine then
stores this key as well as an internal reference to the object.

so for each object put in relation we have:
- a key (used by the application to query the engine)
- a reference to the object (used internally by the relation engine to
get the object)

the application only sees the keys until the objects get dereferenced.

But no 1:1 mapping between the key and the object is imposed by any
external IntIds utility. Which make it possible to ask the engine: give
me all the portlets associated to the 'left' slot even though the
'left' slot is materialized in more than one instance.

In your implementation only objects that are identified uniquely can be
put in relation, and it doesn't seem to be a design choice other than a
limitation imposed by the catalog.

might be a not so bad idea to use a catalog ;-)
  

well, you haven't written the catalog indexes yet :-)



I needn't because I just use the FieldIndex from zope.index.

  


I understand, but the idea is to index relations, not simply the
references between in the objects put in relation. My impression is that
you are thinking of a reference engine rather than a relation engine
with the difference compared to the Archetype's engine that references
are stored outside the objects.

Hm, I'm not sure I understand - so it's not the object (more 
precisely: its unique id) that's indexed but some value provided 
by the object - so this is indeed some sort of an attribute 
that's indexed.

This I would prefer to solve using relation objects that 
explicitly handle additional attributes (provided by the objects 
that are connected by the relation) that may be indexed *in 
addition* to the unique ids.

Or let's see this way: The keys (unique ids in the standard 
implementation) are retrieved by an adapter to the relation 
class (providing IIndexableRelation) so this adapter could 
provide something else if necessary.

 In your implementation only objects that are identified
 uniquely can be put in relation, and it doesn't seem to be a
 design choice other than a limitation imposed by the catalog.

Yes, it is a limitation of the default implementation but I'm 
still not sure it is bad, and it can be overcome easily.

there are no known issues.

I believe that leaving the trunk frozen for a substantial length of time
has a chilling effect on the health of the project, which
*contributes* to the length of the beta period, rather than shortening
it.  The poster child for my argument is the 3.1 release cycle, which
lasted for 9 months!

 BTW, I think that Philipp did the right thing. Depending on a specific

Depending on numeric revision IDs obscures intent:  if we aren't going

creating alpha-ish tags from the trunk, and having dependents use
those tags.

Re: [Zope3-dev] Yet Another Relations (aka Reference) Engine...

My 
impression is that you are thinking of a reference engine
rather than a relation engine 



Maybe I just don't see the difference... (There is one, of 
course, but I doubt it is really of relevance in a practical 
context. )

A relation contains several references:
   
a relation between A, B and C involves 7 references:

A with itself
B with itself
C with itself
A with B
B with C
C with A
A with B with C

But a set of references don't make explicit relations, unless the
application know how to interpret the references.

  Sure;)
 
  The guts of the issue are how to know what type of SQL the connection
  accepts so that sqlos can choose the right adapter for it. An interface
  seemed best.
 
 After thinking about it on and off for the last week, I agree now. The 
 simplest, easiest and most effective solution are specific interfaces. *sigh*

Yeah, I just found zope.schema.interfaces and now understand your sigh.

Re: [Zope3-dev] (zope/app/cache/ram.py) class Storage's cleanup problem.

2005-11-12 Thread Simon Hang
Thanks Stephan,

Here is the test:(test_ramcache.py)

class TestStorage(TestCase):

 def test_getEntry(self):

 --snipped--

 def test_getEntry_do_cleanup(self):
 from zope.app.cache.ram import Storage

 s = Storage(cleanupInterval=300, maxAge=300)
 object = 'object'
 key = ('view', (), ('answer', 42))
 value = 'yes'

 s.setEntry(object, key, value)

 s._data[object][key][1] = time() - 400
 s.lastCleanup = time() - 400

 try:
 s.getEntry(object, key)
 except KeyError:
 pass
 else:
 raise cleanup not called

 def test_setEntry(self): --snipped--

[Zope3-dev] branched Zope 2.9

2005-11-12 Thread Chris McDonough
FYI (this is mostly for the benefit of the Five folks), I've created a
Zope 2.9 branch from the trunk as of about 10 minutes ago.  This branch
is frozen for feature work; it may need some changing of externals to
reflect what we want the initial version of Zope 3 that we want 2.9 to
ship with.  I don't know what that version is, so this is a note to say
that if these externals changes get made on the Zope 2 trunk, please
also make them on the 2.9 branch.

I would have created the 2.9 branch in case the current trunk would be 
ready to branch. At least one week ago there were unresolved issues (with 
zpkg I think) that deferred the 2.9 release (scheduled for last Monday). So 
in general what is the current state of the remaining work to get 2.9b1 out 
to the people?
