I have spent some time to run all unit tests of Plone (2.1.1) and
all it's core products on Zope 2.9 and look into the failing tests.
Thanks a lot!
I hope to have tracked the ~200 failing tests down to two of your
changes in OFS.CopySupport.
The first change is in the manage_pasteObjects method of
CopyContainer. There are some _setObject and _delObject calls which
grew a new suppress_events parameter. This breaks the reference
implementation of Archetypes because it uses something based on
BTreeFolder2 to store references and BTreeFolder2 overwrites both
_setObject and _delObject with its own versions.
The BTreeFolder2 inside Zope 2.9 has been modified to also take this
suppress_events parameter. I'm afraid Plone/AT will have to modify
its _setObject and _delObject implementations to take this optional
As I'm quite new to Zope internals I suppose fixing BTreeFolder2 is
the right thing here (adding the new parameter on both of its
methods). But this change might effect some more products which
have overwritten these methods as CopySupport is a base class of
OFS.Folder and so probably of every folderish type out there.
This was the minimal necessary change to have events work. These
products will have to be modified to work with Zope 2.9, there's no
avoiding it. Fortunately the changes are obvious and minimal. BTW
what BTreeFolder2 are you talking about? BTreeFolder2 has been
included in Zope for a while.
The second change is actually related to your permission work.
First of all I have to thank you for your great work :) But I have
found one nasty thing.
CopySupport had the following security declaration:
__ac_permissions__=(('Copy or Move', (), ('Anonymous', 'Manager',)),)
which changed into:
security = ClassSecurityInfo()
security.setPermissionDefault(copy_or_move, ('Anonymous', 'Manager'))
Now the InitializeClass call is actually an alias for the former
Globals call, so no change here. But as you wrote yourself, you had
some trouble with the mysterious __ac_permissions format.
Looking at the actual code in App.class_init in the last paragraph
I'm quite sure that the former code did effectivly nothing so far.
The actual setattr call is inside a 'for mname in mnames:' loop
where mnames is the second element of each security tuple - in this
special case the mysterious () which results in not going through
the 'for mname in mnames:' loop at all.
Yes the previous code did nothing, and it just left the
The new code goes through SecurityInfo.ClassSecurityInfo.apply and,
because there has been a setPermissionDefault, has an available
self.roles dict... Hm I see what's wrong, the SecurityInfo code only
generates permission default roles for permissions which are *also*
mentioned in a method permission setting (the for loop). That code is
wrong, I'll have to fix it.
In the Plone unit tests this results in about 190 failing tests
Could you give me the reference to one or two of these failing tests
so that I can check things are ok after the fix? Is this with a
standard Plone-2.1.1 tarball? Do you run the Plone tests using the
standard Zope method?
as inserting an object into a folder isn't allowed anymore for
normal members because this triggers some code in a Referenceable
class which is based on CopySupport directly, which required no
extra permission so far but now is protected through the 'Copy or
While I guess that protecting the class with this permission has
been the intent it was not in effect so far. So this should be
either reconsidered or at least noted in the changelog. Changing
this in Archetypes shouldn't be a problem (though I'm very new to
Zope's permissions system).
The class is not protected by copy_or_move, the effect of the
declaration is supposed to be that copy_or_move is by default granted
to Anonymous and Manager. But with my changes because of the
aforementioned bug it's not anymore.
Thanks again for reviewing this! I'll prepare a fix soon.
