[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. If there are no objections I'll soon make a CVS checkin of the attached code. Cheers, Yuppie --- -- Tim McLaughlin Chief Technology Officer Siteworx, Inc.

[Zope-dev] override __of__
Is there any way to override __of__ on an object? I've tried it but for whatever reason, Implicit.__of__(self, object) says that self is not an Acquirer even though the object is a subclass of Implicit. I would implement in a traverse hook, but attribute access of that object won't do traversal. :( Cheers, Tim -- Tim McLaughlin Chief Technology Officer Siteworx, Inc...

[Zope-dev] property type
According to docs and testing (in the interpreter) I can make a read-only calculated attribute using property() (I know that setters do not work w/ non-new-style classes). So I tried the following: class CMixin: def getter(self): return 'test' prop = property(getter) and when I try to mix in this object w/ a Folder object, the instance returns for the 'prop' attribute. Is this an issue with pickling or something else? Cheers, Tim -- Tim McLaughlin Chief Technology Officer Siteworx, Inc...

[Zope-dev] two hard questions
Firstly, I'm trying to return a lazy list to a dtml-in, but it seems that the __getitems__ are all called up front This is the class and the print statement shows up in debugging before any debugging output from within the dtml-in: class LazyList: def __init__(self, root, selections): self._root = root self._selections = selections def __getitem__(self, index): s = self._selections[index] print s.getPath() # this is executed for all items before anythingwithin the dtml-in o = self._root.restrictedTraverse(s.getPath()) o.setSelection(s) return o def __len__(self): return len(self._selections) Does this mean that dmtl-in touches all of the objects first for some reason? Or am I missing something? Second hard ?. Is there any way to wrap a Folder subclassed instance within another class so that I can override some methods on an instance by instance basis? I tried doing a .__class__ replacement, but for whatever reason, Zope machinery seems to keep it from taking effect. Any ideas?

[Zope-dev] Re: International Objects
Roger, I've identified a serious weirdness that causes InternationalObjects not to work. It's this... InternationalObjects - works on 2.4.0 and 2.4.0 upgraded to 2.4.1 but does not work on clean 2.4.1 install. This indicates an disconnect between the upgrade and clean install paths (at least that's my first thought). Zope-devers, any ideas?

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.

[Zope-dev] nasty persistence problem
I seem to be in a bad spot. When I restarted Zope after modifying some products, I got a "Could not load oid.." for all URLs. Basically, the only way I could even access anything was by doing an "import Zope" in the Python interpreter and deleting acl_users which is an instance of LoginManager.

Re: [Zope-dev] ZSQL methods lookup vars in REQUEST only (why?)
I agree. However, this is true of all DTML. I mean, its just as true in DTML methods that might REQUEST.set the args to the ZSQLMethod. ie. they could be tricked into REQUEST.set(ing) a false total etc. because they lookup all of their variables in the namespace.

[Zope-dev] ZSQL methods lookup vars in REQUEST only (why?)
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 )

It seems to me that a User should not get to keep their roles in the acquired objects which are above the User Folder in which the user is defined... However, that does not seem to be true according my testing. This is what happens. Imagine a tree like this root-folder1-acl_users \folder2-object1 root has a role called 'User' with 'View' permissions (anonymous is disabled) and acl_users has a user called joe. joe can access objects in folder2 according to the permissions set on the root by using acquisition like this: http://server/folder1/folder2/object1 joe cannot however, access them directly: http://server/folder2/object1 Does this seem strange to anybody else, or have I just been working too long? _________ 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 )

[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.

Magnus, OK, here goes the evil workaround It seems that getUser does not return an acquisition wrapped object, so make your external method this to wrap it (thus giving ownerinfo the ability to determine the user db): def setOwner(self, username): #note: this assumes that the closest User database houses 'username' user = self.acl_users.getUser(username) self.changeOwnership(user.__of__(self.acl_users)) return 'done.' --Tim McLaughlin (tmclaugh) -Original Message- From: Magnus Heino (Rivermen) To: 'Tim McLaughlin'; Magnus Heino (Rivermen) Sent: 5/11/01 1:20 AM Subject: SV: Subject: [Zope-dev] change ownership > could you give me a url, name & pw, and let me take a look at > the zclass? Nope, I'm doing this on my laptop behind a firewall.

Call the external method on the object like this: http://192.168.237.105:8080/foo/setObjectOwner?username=magnus magnus is my username that lives in the acl_users.

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.

RE: Subject: [Zope-dev] change ownership
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. Anyway, the point is that the parameter to changeOwnership is a User _object_.

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. Then investigate those postulations by refactoring code or by doing more detailed logging in the places where you think the problems are. - C > Hmmm, not really sure what I should be looking for :-S > > What ways should I look to run it and what should I do with the output? > > cheers, > > Chris > ___ 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] 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.

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
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. Anyway, what you gave me works! Thanks. It seems I need to override the _vote method (since it is only called once and allows exceptions). As to the other stuff, I'm sure you can enlighten me further as to why. I appreciate the help. Cheers. Tim -Original Message- From: John D.

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.

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. Cheers, Tim ps. I'm not so sure that __getstate__ will do this for me, but that's probably cause I have no idea what __getstate__ does. It just doesn't sound right ;-) -Original Message- From: Toby Dickenson [mailto:[EMAIL PROTECTED]] Sent: Monday, March 05, 2001 12:08 PM To: Tim McLaughlin Cc: '[EMAIL PROTECTED]' Subject: Re: [Zope-dev] is there a hook for before the transaction is committed On Mon, 5 Mar 2001 10:56:38 -0500, Tim McLaughlin <[EMAIL PROTECTED]> wrote: >Is there a hook for before the transaction is committed for objects which >subclass Persistent? __getstate__ ?

[Zope-dev] zpopyda problems with typecasting
Timestamp columns do not seem to be converted to DateTime objects in Zope when used with 2.2.4 and PoPy 1.4.1 and ZPoPyDA 1.0.1. It returns a string object which will not convert to a DateTime without some help. The string returned is this '2001-01-24 21:52:19-05' which does not convert because of the -05 zone at the end. Also note, numerics do not seem to be converted to floats either (they are returned as strings but _.float() successfully). Am I just missing something?

[Zope-dev] problems with LoginManager and proxies
thanks to the excellent tool (tcpwatch) I was able to pinpoint the issue I am having with LoginManager. It seems that it is returning an HTTP/1.0 500 Internal Server Error as the response to the proxy which then tells the browser that the page is a no go (despite the fact that the login page follows as the content). So the browser displays the error message page we all know too well without the content: HTTP 500 - Internal server error Internet Explorer This does not happen it seems when the page is viewed without a client proxy (tcpwatch or other). Note: this request is actually double proxied - I have an Apache reverse proxy setup. Is this problem an Apache issue, or a Zope issue? Please help TIA, and beaucoup thanks on the previous question.

[Zope-dev] strange problem with LoginManager
I am using LoginManager as specified by by dlpierson's HOWTO and everything works fine unless somebody connects via AT&T Worldnet (using a dialup). In this case, the browser displays a 404 error when the login page should be shown. Same machine connected through a LAN works fine, but again connected through Worldnet is a no go. I suspect this has something (maybe) to do with Worldnet's proxies (if they have them) not handling the headers which zope may (or may not) send. Ok, so it's a guess please help. Thanks.

[Zope-dev] Product dev
I'm building a Product in Python and seem to be having some issues with the new registerClass method of Product registering. If I build it all fine as noted in Shane's recent HowTo, the product does not show up in the control panel. Then after much other chasing, I make a purposeful syntax error in the code, and the Product shows up to reflect its brokenness and shows me the syntax error. Then when I try to fix the error, and do a restart, the error still shows as if I had not changed the code. I checked _many, many_ times, and now the code is different, but Zope seems not to recognize the changed code in spite of my deletion of the pyc files.
