Verrryy strange behavior (NameError)
by Andrew Athan 06 Apr '01

I'm getting an intermittent NameError trying to access a variable set in the external scope of LoginManager.py . I call my variable _x and set it directly above where _LogginInUser gets set. I then try to access it directly above a line that accesses _LoggingInUser gets accessed. I just do a simple print 'testing=%s'%_x. I get an exception. The line that accesses _LoggingInUser doesn't. What gives? Now get this ... if I change the name to (13x's) _xxxxxxxxxxxxx , it works. If I then change the name to (6x's) _xxxxxx, it continues to work. If I then change the name to (3x's) _xxx, it continues to work. (2x's) _xx works (1x's) _x doesn't work!!!! If I change the line near the top of the file from _xx='sss' to _xx=0 and change the print to use a %d I get the NameError. If I change the line back to _xx='sss' and the print back to a %s I continue to get the NameError ... even though that exact combination had worked a minute before!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If I then change the variable back to have 13x's it starts working again. Is there some deep problem with the python byte compiler or access control mangling features of Zope? Or am I missing something stupid? What in the world is going on? A.

Security management for groupware
by Eric BARROCA 06 Apr '01

Hello, I'd like to set up a zope server to build simple workgroup management tool. I'd like to have this kind of configuration : - a folder (called for example 'projectI') is owned by 'boss', its manager. - boss can fully manage the folder (add/modify/delete any file) - some users (having the role 'member' in 'projectI' folder) can add files (document, files and images) - an user having the role 'member' can view all files but can only files owned by himself I'm trying to set this up but I can't figure out how to set the permissions of the role 'member'. I've tried many configuration but if an user can add files, he can modify and delete other's files, so... it's a big problem ! :-) Anyone has already managed to do that ? I'm sure it possible but I certainly missed something. I've done some search in ML archives whithout success. Thanks for your help, EB. -- Eric BARROCA <eric(a)netsystems.fr>

This is just normal python. When you want to assign to a global variable inside a function, you have to declare the variable as a global: _stateVariable = 0 class def func() >>> global _stateVariable _stateVariable = 1 -Randy -----Original Message----- From: Andrew Athan [mailto:aathan-zope-list%REMOVEME@memeplex.com] Sent: Friday, April 06, 2001 1:01 PM To: zope(a)zope.org Subject: RE: [Zope] Verrryy strange behavior (NameError) I'm sending this in case my sagga helps some other relative newcomer. I suspect this problem has something to do with python1.5.2's (or Zope's hackery of...) handling of namespaces within modules & classes. What I needed was access to a "static global" variable to store some state for me. (No, I haven't looked into threads, their existance, or such issues in Zope). What I was doing was: _stateVariable=0 .... class .... def fun() .... _stateVariable=1 and this was causing me all kinds of grief. By changing the code to _stateVariable = {'a':0} ... class ... def fun() ... _stateVariable['a']=1 everything works just fine. Now, can someone give me the shortcut to understand WHHHYYY? A.

Now, can someone give me the shortcut to > understand WHHHYYY? When Python sees an assignment to a *variable*, it assumes you want to define a new *local* variable. You must explicitly declare it "global" to be able to change the value of a global variable from a local context. In the second case, you do not assign to a variable, but modify an object (leaving all variable binding unchanged). Dieter

Re: [Zope] html quote of property sheets

Pierre-Julien Grizel writes: > If I type for example "<" in the title property of a DTML Document, it is > showed as "<" when I valid the property form. As you have probably guessed, the corresponding DTML object lacks a "html_quote". A further (even better) alternative would be to use the entity syntax. How about locating the object, fixing it and sending a bug report with patch into the Collector? Dieter
