[Zope-dev] Python Base Classes, ZObjectManager, and Subobjects (fwd)
I'm transitioning a product from pure ZClasses to a hybrid product python base
classes and ZClasses. So this is my first time working with python
products.
I'm trying to setup a python base class to provide a central place to
subclass ZObjectManager and CatalogAware that I can rebase later
without the ZClass hassle. But when I try to create a ZClass in the
product and subclass to one of my python base classes, I don't get the
subobjects tab in my ZClass.
Clearly I'm missing somthing basic here, but I have scoured the docs
and mailing lists for a clue before coming here. BTW, I did find this
post earlier that no one seemed to reply to, and below that are my
actual python files.
From the quoted message I can see that I need to do something with the
_zclass_, propertysheets, and manage_options of my base class. Is
this documented anywhere. I just gave up on reading the code.
---quoted message---
I want to create a Python base class that inherits from the
ObjectManager and has the Subobjects tab in the ZClass management
screen. Inheriting from OFS.ObjectManager.ObjectManager does not do
this - I need to inherit from ZClasses.ObjectManager.ObjectManager.
I still don't know how to have the Subobjects propertysheet thing
work. I've tried the two ways I listed in my last email of doing
this, but I can't get it to work.
One way was:
class MyObjectManager(ZClasses.ObjectManager.ObjectManager):
class ZMyObjectManager:
Mix-in for Object Management
_zclass_=myObjectManager
propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets()
manage_options=(
{'label': 'Subobjects', 'action'
:'propertysheets/subobjects/manage'},
)
and then register ZMyObjectManager as a base class in __init__.py.
The other way was:
class MyObjectManager(ZClasses.ObjectManager.ObjectManager):
propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets()
manage_options=(
{'label': 'Subobjects', 'action'
:'propertysheets/subobjects/manage'},
)
and register that as the base class. Neither of them work.

Dieter Maurer wrote: Zope 2.4.3 will not work with Python 2.1.2. This is not literally true. Zope 2.4.3 will work fine with Python 2.1.2. However, Python 2.1.2 doesn't ignore stacksize computation problems like Python 2.1.1. Instead of silently corrutping memory and continuing like 2.1.1, Python 2.1.2 will stop with an assertion error. This means that Zope 2.4.3 won't really run under 2.1.2 for very long if you've got a codepath that tickles a compiler package bug, but at least it won't fail mysteriously with odd symptoms. Zope 2.4.3 will run for *longer* under Python 2.1.1, but it will fail with other more mysterious symptoms. Hopefully, this will clear some of the confusion up. For maximum stability if you're running some 2.4.X-series Zope under Python 2.1.X: - Upgrade your Zope to 2.4.4 (wait for final if you don't like the current beta status of 2.4.4) - Upgrade your Python to 2.1.2 Do these two steps *at the same time*.

You exclude the self first argument of a static method. The first argument of a class method is where the class is passed. The reason that self is now excluded when defining interfaces comes from considering who reads interface definitions. By their nature, interfaces are meant to be read from the outside; from beyond the facade. The self attribute of methods is an implementation detail, and is not a concern of those who make calls on an interface. With Python2.2, you can demonstrate this by defining a class that has static methods only, but which still satisfies some interface definition. The self argument need not occur at all. -- Steve Alexander ___ 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 )

No. Can you expand on this a little? It doesn't make sense to me to exclude 'self'... Jim [Fulton] explained it to me once. He can explain it better than I can. But think of it this way -- theoretically, an interface can be implemented by a folder full of Python scripts as [relatively] easily as it can be implemented by a class. Should you then include all of the binding options (context, container, etc)? Or, if you were defining the interface in IDL (mmm, almost-avoiding-redundancy through acronyms!) with the target language being Python, would you include self? An interface defines a contract on the usage of an object/component; it's not necessarily a specification on how to implement it. The concept of 'self' as the first argument for instance methods is a product of implementing in a Python class (not to mention that 'self' is not a required name, just an extremely common convention. You could use 'this' just as easily). The big theory behind most component models is that the implementation shouldn't matter so long as certain interfaces are satisfied. And the following simple interface could be satisfied a number of ways in Zope already - by a normal Python class implementation; by a folder with a Python Script or External Method; by a ZClass with the same; or (in Python 2.2) by a class with a static method (which would have no 'self'). class ISubscriber(Base): Subscriber base interface def EventService_inform(event): Informs the subscriber that the event has occurred -- Jeffrey P Shell www.cuemedia.com ___ 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 )

Can you try to start Zope with the environment variable ZOPE_SECURITY_POLICY=PYTHON set to see if the problem continues? Are you using any database adapters or other C extensions?

[Zope-dev] Re: Python Base Classes, ZObjectManager, and Subobjects
Nobody's really answering and I keep getting both closer and further
looking at the ZClasses code. As I understand it now,
ZClasses.ZClass.createZClassForBase is supposed to address the ZClass
meta class issues such as creating the _zclass_ in addition to the
actual class and handling propertysheets. So I would assume that my
error lies somewhere in there, but I can't figure it out.
A few more notes, when I create a ZClass that subclasses my python base
class which in turn subclasses ZClasses.ObjectManager.ZObjectManager,
it creates a ZClass with a default View for Subobjects. This
seems to indicate that somewhere the subobjects propertysheet is being
treated as an instance propertysheet rather than a propertysheet of
the ZClass meta class.
Also, when I create an instance from such a ZClass, trying to access
the instance in the ZMI yields an authorization error. Following is
the traceback:
Traceback (innermost last):

I would assume this happens because the
propertysheets/subobjects/manage method listed in the view tab is not
valid for the instance, but trying to call that method on the ZClass
directly returns:

I have also tried the two variations in the quoted message below.
Then I tried the two variations below except substituting
ZClasses.ObjectManager.ZObjectManager for
ZClasses.ObjectManager.ObjectManager. All with the same results
Again, my goal is to be able create a ZClass that subclasses a python
base class that in turn subclasses
ZClasses.ObjectManager.ZObjectManager in such a way that the final
ZClass and any other ZClasses that subclass it have a subobjects tab
in the management view of the ZClass. Thanks.

I'm trying to setup a python base class to provide a central place to
subclass ZObjectManager and CatalogAware that I can rebase later
without the ZClass hassle. But when I try to create a ZClass in the
product and subclass to one of my python base classes, I don't get the
subobjects tab in my ZClass.
Clearly I'm missing somthing basic here, but I have scoured the docs
and mailing lists for a clue before coming here. BTW, I did find this
post earlier that no one seemed to reply to, and below that are my
actual python files.
---quoted message---
I want to create a Python base class that inherits from the
ObjectManager and has the Subobjects tab in the ZClass management
screen. Inheriting from OFS.ObjectManager.ObjectManager does not do
this - I need to inherit from ZClasses.ObjectManager.ObjectManager.
I still don't know how to have the Subobjects propertysheet thing
work. I've tried the two ways I listed in my last email of doing
this, but I can't get it to work.
One way was:
class MyObjectManager(ZClasses.ObjectManager.ObjectManager):
class ZMyObjectManager:
Mix-in for Object Management
_zclass_=myObjectManager
propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets()
manage_options=(
{'label': 'Subobjects', 'action'
:'propertysheets/subobjects/manage'},
)
and then register ZMyObjectManager as a base class in __init__.py.
The other way was:
class MyObjectManager(ZClasses.ObjectManager.ObjectManager):
propertysheets=ZClasses.ObjectManager.ZObjectManagerPropertySheets()
manage_options=(
{'label': 'Subobjects', 'action'
:'propertysheets/subobjects/manage'},
)
and register that as the base class. Neither of them work.

Re: [Zope-dev] [BUG] Python 2.1.2 Zope 2.4.1
Olivier Deckmyn wrote assertion STACK_LEVEL() = f-f_stacksize failed: file Python/ceval.c, line 687 This is a new assertion, put in to catch the case where the RestrictedCompiler code used by PythonScripts incorrectly calculates stack size. After some hours of researches, I have a (dirty, really) fix : I had to modify Python sources and hack line 687 in ceval.c : I removed it... This is _not_ a fix, any more than putting in a signal handler for SIGSEGV that ignored it and kept going would be a fix for a segfault bug. The bug is _real_ and causes memory corruption. The most likely result is that Zope will crash mysteriously, some time later down the track, but it's also possible you'll end up with random data corruption. This is _far_ worse than just a crash. If upgrading to 2.5 or 2.4.4-to-be is not an issue, just replace the lib/python/RestrictedPython package in your Zope installation and reboot. Please, please, please, don't propagate dodgy and incorrect fixes like the above (removing the assertion). The assertion is in the code for a very, very good reason.

But couldn't find another way to have my servers restart this sunday. I just regret that this problem was not warned anywhere clearly. I must not be the only one that have had seen this happen ! But I know it now :-) Anyway, many thanx to every one who gave help.
