[Zope-dev] checkPermission and proxy roles
Issue #'s 78, 846, 1125 all relate to checkPermission not considering proxy roles. #78 was resolved, however, from the looks of the code (and I haven't tested this), it will fail to Cut/Paste because the 'Delete objects' perm would be permitted by the proxy role which is not considered in the checkPermission. Anyway, the question is this... Why doesn't checkPermission consider proxy roles? I found the following discussion in Zope-CMF and it looks like this was fixed in CMF, but it seems to me like this should be the default policy behavior in Zope. We can do the patches if there's no reason for it being the way it is... Cheers, Tim begin quote Dieter Maurer wrote: I think, we should have both possibilities: [1] check whether the real user would have the permission (independent of proxy roles) [2] check whether the current context has the permission (dependent on the current proxy roles and other execution security aspects (such as ownership)) I'd like to replace utils._checkPermission in CMF HEAD with the attached code. This would change the behavior of _checkPermission from [1] to [2]. (If I didn't make a mistake.) The way utils._checkPermission is used in CMF implies possibility [2] would be the right behavior, the fact it implemented [1] looks like a bug to me. I don't know of any code that'll break if we switch to [2]. I can see there might be a need for [1]. But in this case you can use Zope's checkPermission method.

Re: [Zope-dev] nasty persistence problem
Thanks Chris, I'll hold on to that for a rainier day. I just worked
this one out in a very roundabout way ;)
A product had gotten copied in that moved a Product class from one
module to another even though everything else was the same. It seems
that ZODB doesn't like that. So, somehow, that caused all kinds of
unrelated problems. I put the product back to the way it was, deleted
acl_users through python, restarted, went in and undid the Global
Registry Rebuild and the delete and voila! It works again.
Thanks,

I seem to be in a bad spot. When I restarted Zope after modifying some

Basically, the only way I could even access anything was by doing an

an instance of LoginManager. And now I found out (once I was able to
login to ZMI) that two vital ZClasses are broken also.
So, I'm kinda stuck. Here's the error:

I've been asked too many times now by developers what is wrong when they call ZSQL Methods without passing parameters because their parameters are in the namespace. This seems to make sense to all new Zopers (and some older ones like myself) because all other DTML lookups are in the entire namespace. Anyway, I propose that ZSQLMethods change and do variable lookups in the entire namespace, not just the REQUEST object. It seems to be a simple enough change (at least it looks it) and I can submit the patches, but the harder thing is to get people to agree that it is a change for the better. The only argument that I have heard against it is that variables will be found mysteriously through the stack and that this is harder to understand. However, that just makes it inconsistent with all other DTML and therefore mysterious in its own way. Consistency is much better for learning and for remembering, and DTML in ZSQL should work the same as DTML in DTML Methods, etc. Please consider this and abuse me as appropriate ;) Regards, Tim -- Tim McLaughlin iterationZERO - www.iterationzero.com 703.481.2233 ___ 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 ) -- Tim McLaughlin iterationZERO - www.iterationzero.com 703.481.2233 ___ 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 )

Stian, It's probably nicer to use the -P option for z2.py which allows you to specify a port offset for all ZServer services. ie. -P 8001 puts http on 8081 and ftp on 8022 or -P 8002 puts http on 8082 and ftp on 8023 --Tim PS. sorry all for the Base64 encoding on the previous message. _ Tim McLaughlin Iteration Zero - www.iterationzero.com 703-481-2233 Message: 8 Date: Mon, 11 Jun 2001 12:04:31 +0200 (CEST) From: Erik Enge [EMAIL PROTECTED] To: Stian Jenssen [EMAIL PROTECTED] cc: '[EMAIL PROTECTED]' [EMAIL PROTECTED] Subject: Re: [Zope-dev] multiple servers!

[Zope-dev] disable view on method for ZClass
OK here's a strange request that I think should be changed on ZClasses (bear w/ me): 'View' permission should be disablable on a method of a ZClass. Right now, it forces 'View' to be mapped to 'View' if one tries to disable it. The reason is the event model that I am making available for ZClasses. One such event is the onPropertyChange which passes (self, propertysheet_id, changes, REQUEST) to the ZClass method. This is all well and good except that the same method can be called TTW, and thus forged. Worse yet, the changes param could be forged so that the method has false params. Disabling the method for TTW calling cleans everything up nicely. Anybody have any thoughts? Also, does anybody have any idea where it is currently getting the default set... I can't seem to find it.

I call the external method like this from DTML... set_owner(restrictedTraverse(path_to_user)), where path to user is a physical path, but I'm using the ZUserFolder, so I can use the restrictedTraverse to get to users. UserFolder has a different API. You could do this if your acl_users is a standard UserFolder... set_owner(acl_users.getUser(user_name)) in DTML or make your external method this... def set_owner(self, user_name): self.changeOwnership(self.acl_users.getUser(user_name)) OK, so that should keep you busy for a while.

Do you have multiple acl_users objects in the acquisition context of the
object? Because if you do and the self.acl_users will acquire (possibly)
the wrong user database. If that's not the problem, I'm gonna have to let
it cook, and I'll probably come up w/ somethin' later.

This tells you how many *other* requests were unfinished at the end of a particular request. So for instance, if you run requestprofiler like this: python requestprofiler.py log.file.name --detailed And you see a profile line like (header added for reference): startwin wout wend tot S osize code act url 2001-04-19T01:19:420 120 12 E 26024 2005 /Catalog/checkrep?P This means that: - this request started at 2001-04-19 1:19:42 UTC (start) - zserver waited 0 secs for input from the client (win) - zserver waited 12 secs for output from the publisher (wend) - the total time from start to end for the request was 12 secs (tot) - the request reached the end (E) stage (S, one of E, A, I, B) - the output size in bytes was 26024 (osize) - the http code was 200 (code) - the number of pending requests at the end of this request was 5 (active) - the URL of the request (url) Hangs are also interesting. Use detailed reporting to sort by end stage: requestprofiler.py your.log.file --detailed --sort=endstage Any requests that don't show a stage of E for their endstage were hung requests. You can also use cumulative reporting to sort by hangs: requestprofiler.py your.log.file --cumulative --sort=hangs This will show the methods that hung most frequently. Much of the time, you can find problems this way by seeing methods that enter an infinte loop or cause a segfault. Total time is also interesting: requestprofiler.py your.log.file --detailed --sort=total Shows you individual calls to methods that took a long time. - AND - requestprofiler.py your.log.file --cumulative --sort=total Shows you where most of the request time is spent. The goal is to indentify methods or requests that take a long time, don't return, or are accessed frequently. If you can match this data up with specific problems you've experienced (possibly by way of times/dates), it becomes easier to form postulations about what is happening to Zope under load.

[Zope-dev] un-own an object
Ok, so imagine a DTML method has an owner, and as the docs say the method can do no more than the authenticated user and the owner's permissions combined. So, now delete the owner. The DTML method will no longer be functional, since the owner does not exist, and has no permissions. I found this to be true with ZClass constructors at least. I believe that the method should take the permissions of the authenticated_user only in this scenario, but it does not.

[Zope-dev] ZUserFolder usage and development
Dave, 1. I say sync because UserFolder keeps its objects in an attribute called "data" (list of Users) whereas ObjectManager does not. The 'name' attribute is no longer necessary because I usee the id of the object and allowing it to be specified presents potential discord. 2. Correct, you're supposed to check for that in your constructor, but this is a new Product and could obviously be changed. In fact, I'm thinking of eliminating the constructor params altogether and allowing them to be set later. manage_editUser does check that password and confirm match since in fact it calls the Super. 3. I'm gonna pitch this out. say it all to the benefit of all. Incidentally, great working with you on this. Excellent feedback, and your catchin' on quickly (hooray! another infected by the Zope bug).

[Zope-dev] get_request() idea
I'm making some mod's to the property sheets to allow them to fire an event (call a hook) when they change on an instance. Anyway, it looks like I'm gonna have to hand the REQUEST object all around, so I can get the data out of it that I need (as well as allow other inspection in the future). Anyway, I propose that we could make Zope internals many times simpler by having the REQUEST object available in all places Python simply by calling get_request() (a __built_in__ method much like get_transaction). This may even speed up Zope since in fact, no stack space will have to be managed for the REQUEST object to be passed to methods that might or might not need it.

RE: [Zope-dev] is there a hook for before the transaction is committed
I want to be able to raise an event from the property sheets to the product if a property changes. I'm calling it manage_afterChange. I want it only to fire once per transaction so that multiple changes are aggregated. Here's the declaration I have in mind. manage_afterChange(oldItems, newItems) oldItems: dict of id - values before modifications newItems: dict of new values at end of transaction This would allow an elegant "reindex" or notification system for objects. It would also allow for validation (ie. raise error if you don't like newItems). Anyway, that's it. I'm halfway there, just can't get a method to be called on my object _just_ before commit.

RE: [Zope-dev] is there a hook for before the transaction is committed
In what respect are the _v_* attribs gonna cause problems. My guestimate was that they disappeared upon transaction commit/abort. I'm also not sure as to why I would need subtrans since I'm only messing with properties of the object. To my knowledge, subtrans are only necessary to conserve resources.

I've tried to make it more obvious and better documented. 2) Don't use this kind of functionality, but rather use sub-transaction commits. The first suggestion has more overhead than what I assume you would need, but the second one won't work for all situations. A Fishbowl proposal of mine, HashingSupport, was going to use the same kind of hook you are asking about. In this case though, using sub-transaction commits made a lot more sense. In general though, I think that _v_* attributes pose a non-trivial problem that probably requires a hook on abort() if not commit() as well.
