[Zope-dev] Puzzling change to guarded_getitem in Zope 2.8
I'm migrating our 2.7-developed Product to 2.8. The following change has me
puzzled. In 2.7, AccessControl.ZopeGuards guarded_getitem has the following
code:
def guarded_getitem(object, index):
[ snip handling of slices ]
...
v = object[index]
if Containers(type(object)) and Containers(type(v)):
# Simple type. Short circuit.
return v
if getSecurityManager().validate(object, object, index, v):
return v
raise Unauthorized, 'unauthorized access to element %s' % `i`
note the use of index in the validate call. In 2.8, this appears as:
def guarded_getitem(object, index):
[ snip handling of slices ]
...
v = object[index]
if Containers(type(object)) and Containers(type(v)):
# Simple type. Short circuit.
return v
if getSecurityManager().validate(object, object, None, v):
return v
raise Unauthorized, 'unauthorized access to element %s' % `i`
where index has become None. This would appear to imply that we can't
perform access controls on a per-item basis in sequences or mappings, unless
we do so in the actual __getitem__ method, which implies there's no such
thing as trusted code. We have an access policy implementation of:
def _checkAccess(self, name, value):
if name.startswith('CG'):
return 1
if self.isValidAggregateName(name):
return 1
return 0
security.setDefaultAccess(_checkAccess)
which obviously doesn't work any more, since name is never a item name, it's
always None.

[Zope] Migration pains going to Zope 2.8
I can't instantiate out Product, which is a bit of a hurdle :)
Our Product's registration looks like this (this function is invoked from the
Product's __init__.py):
def initialize(context):
''' Register the CGPublisher class '''
context.registerClass(
CGPublisher,
permission=Perm.ADD_CGPUBLISHERS,
constructors = (addCGPublisherForm, addCGPublisher, addValues,
getMode),
icon='www/CGPublisher.gif',
visibility='Global',
)
Unfortunately, the addCGPublisherForm template can't access the addValues
function. The specific error I get is:
Error Type: Unauthorized
Error Value: The container has no security assertions. Access to 'addValues'
of (App.ProductContext.__FactoryDispatcher__ object at 0xb61d30cc) denied.
I tried adding some module security declarations:
security = ModuleSecurityInfo('Products')
security.declarePublic('CGPublisher')
security = ModuleSecurityInfo('Products.CGPublisher')
security.declarePublic('addValues')
security.declarePublic('getMode')
to the initialize() function, but that didn't change anything. Any
suggestions?

If so, you may want to analyse the FactoryDispatcher mentioned
above.
You get it (in an interactive interpreter) via
app.manage_addProduct[your Product]
In its class, you should find your contructors as
well as permission attributes of the form constructor_name__roles__.
Apparently, addValues__roles__ is missing (for whatever reason).
The ProductContext is creating the attributes correctly on the Product's
custom FactoryDispatcher class. The correct class is being used, and the
*__roles__ attributes are all present and accounted for when the validate()
is invoked. The problem appears to be that we don't even get up to checking
those attributes. The addValues function has no __roles__ attribute, so we
wander into __roles__ attribute checking on the container and fall about
laughing. So I added __roles__ to addValues:
addValues.__roles__ = ('Manager', )
and now everything works. I even removed the ModuleSecurityInfo declarations,
since they appeared to have no effect at all. There's probably some API for
setting that __roles__ attribute, but I'm stuffed if I can find it.
Thanks for the help Dieter,

[Zope] Pluggable Auth Service ... how is it used?
I'd like to get session-based login going, and on the surface PAS appears to support that. First up, is there any documentation? I've set up in my PAS acl_users the following objects: 1. cookies - a Cookie Auth Helper active for Challenge 2. session - a Session Auth Helper active for Extraction, Update Credentials and Reset Credentials 3. users - a ZODB User Manager with a single user test 4. roles - a ZODB Role Manager with the test user assigned to Manager Then accessing a Manager protected method inside the folder brings up the login form from the Cookie Auth Helper, but submitting that form does nothing (it returns the empty form to me). Switching the cookies object to handle Extraction, Update Credentials and Reset Credentials makes the login work, but I'd like to use the session. The docs that come with the product talk about Decorators and Property Sheets used to extend the user properties, but I can't even find anything with either of those names in the UI. The interface has Scriptable Plugin with a teasingly disabled Validation interface -- which I have found to mean user validation. I'd like to enforce valid email address capture ... when I can figure how to actually capture an email address, that is.

This is what Fernando appeared to do in the end. Having sessions persist across ZEO restarts is a handy thing. Also, I never figured how to configure a temp storage in a ZEO server. I started looking once, but either ran into a dead end or got distracted (or both ;) There are no well-maintained nonundoing storages that I know of other than temporarystorage. Once upon a time, BerkeleyStorage minimal used to work, but its gone the way of the dinosaurs apparently. And I distrust anything related to Berkely DB :) I think any sessioning setup that uses a ZEO-backed storage will be more conflict-prone than one that doesn't use ZEO, just because the transaction commit time is typically longer. I'm not sure if this is the problem you mention. Could be. Probably not hard. You could write a session data manager implementation that used a relational database. The interface for those things is in Products/Sessions/SessionInterfaces.py Yeah, I remember poking around that code way back, and it seemed reasonable. Its interactions with transactions are the bits that scare me. Using a standard RDBMS connection would probably solve that though.

That will work, and I don't see a need to deprecate it. Eventually, though, I expect products to migrate to ZCML-based security declarations. Is this a general trend for Zope 2? I'd rather see Zope 2 kinda avoid ZCML if possible. It's just one of those personal preference things, I suppose, but I know I'm not the only one who isn't that enamored of the ZCML approach. I actually like having the declarations all in the python code like it is in Zope 2. I'd like to see the declarative style that Zope 2 move to using decorators. I was sitting in a presentation at PyCon talking about MetaClasses, and I finally *got* them. I realised that the security declarations in Zope 2 are a perfect fit for metaclasses and decorators. If only I had the time to actually implement this dream ;) Note that this all comes from the perspective of someone whose only exposure to Zope 3 has been through two sprints. I've not actually tried to develop any sort of application using it. My day job is very firmly fixed in Zope 2, and isn't likely to change for a long time.

- declaring object security on the acquiree via

For me, the problem arises when the acquiree is a Python builtin object - a
string instance attribute in my case. Hence I can't make any useful statement
like the above. I have a statement::
security.setDefaultAccess({'secure_url': 1})
on the class, but with the change discussed here, that assertion is never
looked up. I attempted to::
security.declarePublic('secure_url')
but of course that didn't change anything, as I mentioned the class assertions
weren't being looked at.
After poking around some more, I realised that validate()
(VerboseSecurityPolicy's) was being invoked with::
aq_chain(container) = [

context = AccessControl.SecurityManagement.SecurityContext instance at
0x413cabec
aq_chain(value) = ['http://secure.cgpublisher.localhost']
That is, there's no acquisition context on the simple string. To fix the
problem, I changed secure_url to be a ComputedAttribute which looked up the
instance attribute _secure_url. This then gave the value a valid acquisition
chain and everything works now.
I'm really sorry I can't be more helpful and produce a useful test case, but
I've a bazillion deadlines falling on the floor. Maybe in a few months. For
now I just needed a work-around that will let me run in an un-patched Zope.

[Zope-dev] 2.7 branch: attribute permission problems

Hash: SHA1
[might dupe - sent the first copy of this from the wrong address, sorry!]
I've just upgraded to use the bleeding-edge 2-7 branch (from 2.7.2, running in
py 2.3.3) and I've started getting permission problems with attributes. The
cause appears to be acquired attributes. With VerboseSecurity installed
(note: behaviour not dependent on VS - I checked), I get told:
Error Type: Unauthorized
Error Value: The container has no security assertions. Access to 'secure_url'
of (CG Conference Proposals proposals at 0x41387b40) denied.
The secure_url attribute is defined at a much higher object, where we have a
declaration including:
security.setDefaultAccess({'secure_url': 1})
On the proposals object though, we don't have any delaration for the
secure_url attribute. If I add one, or a general
security.setDefaultAccess(allow), then the error goes away. This doesn't
seem correct to me.
The relevant change in CVS appears to be:
*** ../../../../Zope-2.7.2/lib/python/AccessControl/ImplPython.py 2004-02-10
17:46:02.0 +1100
- --- AccessControl/ImplPython.py 2004-09-15 09:59:41.617423171 +1000
***
*** 551,560
return v
validate = SecurityManagement.getSecurityManager().validate
- - # Filter out the objects we can't access.
- - if hasattr(inst, 'aq_acquire'):
- - return inst.aq_acquire(name, aq_validate, validate)
- - # Or just try to get the attribute directly.
if validate(inst, inst, name, v):
return v
raise Unauthorized, name
- --- 551,556
The change note being - Removed DWIM'y attempt to filter
acquired-but-not-aceessible results from 'guarded_getattr'. and I'm not sure
what that means :)

IOW, it looks like it used to find the first secure_url it could access and return that, even if there were other acquirable secure_url attrs before that one in the acquisition path. I'm sure the fact that it ignores any intermediate (but inaccessible) secure_url attrs is what Tres meant by DWIM. I *think* you're implying that there might be more than one secure_url attribute in the acquisition path? If so, that's not the case. There is only one, and it's on B. Or perhaps what you're saying is that in the pre-patch days, if there *was* an attribute on A, then validate() would do the Wrong Thing, or something otherwise bad would happen. I'm a little confused about why I'm the only person seeing this, BTW... But I'm not sure that he intended for the patch to have this effect. I'm not even sure why it does have this effect; the validate function is just too byzantine to understand without taking it through the debugger. You can say that again.

While the load script is running (it runs on the command-line and goes TTW using urllib to register the users) if I access a page which summarises all users, I *sometimes* get None for some of the users. The page uses a Catalog to find basic user info, and sometimes uses getObject() to find the real user object. The getObject() appears to return None sometimes.

(For example, you can't even run mkzeoinst.py without having a directory named Zope hanging off of sys.path.)

Where panelClass is my Product's class.
When the ping script imports Zope, the product is installed. If it's
installed as a regular product, using context.registerClass, all is OK. If
it is installed using the above function, I get ZODB transaction notes of the

It's all a bit black magic for me though. I honestly don't know why half of

No, but it is being pinged. By that, I mean that we have a script that
tries to access the ZEO server every five minutes to make sure it's all OK.
The script does the following::
import sys, os
sys.path.append('/app/zope/zopecontrol_code/')
sys.path.insert(0, '/app/zope/zopecontrol_code/lib/python')
os.environ['ZEOPORT'] = '8076'

import Zope
# now do stuff with the Zope.app() (we don't actually have to do anything
# to trigger the ZODB note generation - the import is enough)
Setting the environment var ZEO_CLIENT stops the message - but I guess I'd
like to know why this product is causing the message when none of the others
are. It's all due to the code in installControlPanel, and I'd rather it not
be dodgy :)

[Zope-dev] Call Profiler strangeness - lots of ZODB transactions
I'm investigating why our product ZODB is growing when it shouldn't. I've found that the undo log has entries in it every five minutes saying Installed product CallProfiler by Zope. More infrequently (not regularly) we also have Installed product ZOracleDA by Zope. The Call Profiler was designed specifically not to hit the ZODB - it's in-memory only with. Our setup consists of seven ZEO clients talking to the one ZEO server - the one that's getting all these hits in the ZODB. Does anyone else see this happening? Anyone have any ideas why we're seeing this behaviour?

I'm not sure the consentual monkeypatch approach really solves this issue... and if the product has to be modified to make it register itself with the profiler, why not just have it include the (very simple) calls to the profiler instead?

I've just announced our Call Profiler product on zope.org and the zope announce list (waiting for people in different timezones to authorise them :) ( http://www.zope.org/Members/richard/CallProfiler/ for the impatient) In a nutshell, it patches the rendering guts of DTMLMethod, ZSQL, etc. and the ZPublisher so that we can get timing marks for requests as the calls are made. The patching is quite simple (once I got the hang of it ;) and reversible, and means that there's no changes required to the Zope core to enable the testing (which our initial versions did). It does pose a question though: would it be better to have support for this stuff in the core, or is it OK for a product like this to dynamically patch the call methods when it needs to? On one hand, the performance hit when dynamically patching the methods is zero when the product is not active, but it does mean diddling with methods that really probably should be left alone.

So does that mean they have different names in the service manager? How do you configure the instances?

Seriously though, once an instance is configured, why would you want to change it? (Assuming you get it right that is) Mostly the interface is for stopping/starting the server, accessing the log, accessing the management screen, adding a manager user (yes, those last two are buttons which just open a URL with the default browser), changing the emergency user password and generally reporting information about the instance. The (Assuming you get it right that is) is also spot on - people will do strange things, and we need a simple interface that we can walk them through on the phone, and also an interface that they're unlikely to cause damage with (as opposed to editing z2.py or the *gak* registry!) This interface is _specifically_ targetted at a new breed of zope user. Someone who was brought up on a diet of IIS or some other plug-n-play web server. Someone who just wants it to work, no registry editing, no config file editing. That's who this stuff is targetted at. I'd say that adding a multi-instance ability would be possible - we'd just have to be able to handle multiple config files. We're just not sure how it should be handled in the UI :) Richard ___ 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 )
[Zope-dev] Zope on Windows: enhancements proposed
We've got a wonderful zope control panel (which installs into the standard
windows Control Panel) and zope service which we'll be making available in
binary and source form this week. Like the Mac OS X controller, this is
simply a trivial re-branding extension of our work in supporting the
usability of our Bizar Shop product.
The windows controller works on win95/win98/NT/win2k. It controls a real
windows service on platforms were services are run (NT/win2k), and otherwise
controls a service daemon which stays in the system tray. We'll call this
service Zope, and its job is to lauch python [script] [args] with some
Zope-specific environment fiddling (INSTANCE_HOME env, cd ${SOFTWARE_HOME},
STUPID_LOG_FILE env).
The current method of starting Zope as a windows service using
PythonService.exe is kludgy, mostly because of the unnecessary layer of
python. The Zope binary distribution's use of PythonService.exe does the same
thing that our Zope service does (in the end), which is to lauch python
z2.py [args].
We'd like to propose that the service distributed with Zope move over to
using our code.
Our control panel will be able to control Zope (WebSite), but we probably
won't offer the ability to configure it (editing the z2[s].py file in-place
is possible - we do that now - but it's rather hackish).
So, best scenario is that Zope ships with the controller and our service.
Worst scenario is that the controller is downloaded separately and can only
stop/start PythonService. In the second case, we'd still ship our service and
install it - meaning that there'd be two Zope services in the service
manager, but at least the controller, which appears in the control panel,
would still be able to fully control Zope.
As a separate issue - we're curious about the naming of the Zope installation
- why is it called WebSite (and the Zope service Zope (WebSite))? The name
clashes with another product that's fairly well-known in the windows
community originally from O'Reilly: http://www.oreilly.com/software/index.html
... and since Zope is a fairly distinctive name ...
Richard
ps. happy to put this up as a project if required.

Great, Im really looking forward to an improved Windows installation. But lets get it out there play with it before anything major happens like shipping Zope with it :) Fer sure :) It is annoying but Zope wins there because OReilly isnt making WebSite anymore. Yeah, they seem to have sold it to someone else... Its just a name, I find the Zope (%s) bit more annoying than anything :) Agreed. ps. happy to put this up as a project if required. Thats probably a good idea. What about other issues such as install and removing service easily later, STDERR logging not going to /dev/null, lack of start menu icons and other windows issues... These are all things we've addressed, but it'd be good to note them somewhere. We've tried to make the process of using Zope (and hence our product) as painless to the average Windows user (and Mac user) as possible.

Paul says: I think the goal should be for Zope and Python to converge on the same license, with perhaps the new license being some off-the-shelf license like Apache's. Hmm. So a BSD style license, then. Are there currently any Zope-derived distributions that are proprietary (third-party or DC's)? Absolutely! We use Zope as a core component in our product that's about to hit the shelves. If not, does DC anticipate there being this kind of third-party proprietary derived distribution in the future? Absolutely! We have several products in mind that are based on Zope. Other than keeping the door open for this eventuality, is there any other reason to choose a BSD style license over the GPL? I think I've answered that question. We will be distributing the entirety of the source code of all open-source components of our product. We cannot distribute the source code of our product - that would be sheer foolishness. We've invested about 2 man-years in the code, and we're not about to just give that away. Our investors would string us up!

[Zope] REQUEST.set('n', n+1) broken on zope.org
As the subject says, REQUEST.set('n', n+1) is broken on zope.org. The
following DTML will raise an AttributeError on __add__:
dtml-call REQUEST.set('n', 1)
dtml-call REQUEST.set('n', n+1)
Is this a permanent change and is this going into the Zope codebase?
