[Zope-dev] CST 0.8 Question
Hi Chris, While writing the CST 0.7 - 0.8 updater, I noticed something weird in SessionIdManager.py. In constructSessionIdManager(), you call SessionIdManager.__init__ with a final parameter called 'rewritemode'. I don't know what that's meant to do, but all I can see is that it results in a call to self.turnOn() when you create the manager. The name would suggest that something else should probably happen, but maybe rewritemode is just a relic from a previous version?

[Zope-dev] Trying to set roles/permissions programmatically - Now I have a headache!
Hello! I want to set the roles of a permission and turn acquisition of a permission (mapping) on and off programmatically. And of course I want to get a permission by its name. This looks definitely more complex than simply changing an object's property! I took a look at the management screens(Role.py - manage_changePermissions). The aX and pYrZ mapping for the *checkboxes* (=sole purpose) gave me a lot of confusion, I first thought this was Zope internal naming :-). Then I took a look at Permission.py (setRoles). But I haven't dealt with this before, and it all looks a little weird. I managed to write a couple of functions that give me roles to permissions and permissions to roles or check if a permission setting has been acquired and so on, but I'm stuck with *setting* permissions with a function of my own. a) Could this be correct? # roles as list: acquisition will be turned on roles=['Anonymous','Manager'] # roles as tuple: acquisition will be turned off roles=tuple(roles) # set as specified some_permission.setRoles(roles) b) How can I get a hold of some_permission when I know its name? This does not work: def setRolesForPermission(ob, permission, roles, setacquired): permission_trans = '_' + replace(permission, ' ', '_') + '_Permission' p = getattr(ob, permission_trans) # this does *not* give me the permission itself! if not setacquired: roles=tuple(roles) p.setRoles(roles) It must have something to do with acquisition :-) If it is turned on for that permission, getattr() won't find the attribute. If it's turned off, it returns a tuple. Where's the permission instance itself? I see that ac_inherited_permissions(1) gives me a list of permission names, but I don't know how to access a specific permission directly. This *did* work: def permissionAcquired(ob, permission): # Tell me if acquisition has been turned on # (There's also some other way, checking if the returned is of type List or Tuple, I think I saw that somewhere in Role.py) permission_trans = '_' + replace(permission, ' ', '_') + '_Permission' return (not hasattr(ob.aq_base, permission_trans)) Help!

[Zope-dev] Zope Server hanging :-(
Hi, Well, I thought the upgrade to 2.3.2b2 would solve the problem but it hasn't :-( I have a (very important :-S) Zope instance which hangs at what seems like the slightest touch. The symptoms are as follows: 1. Go to a given URL, which doesn't respond (browser sits and spins) 2. Doing a 'top' on the server shows python nowhere to be seen (so it's not infinite-loop-processor-hogging) 3. ps shows the python threads are all still there, but none of them will respond. 3. doing a ./stop sucessfully stops Zope (the broswer returns a 'reset by peer') 4. doing a ./start yields the following the the stupid log file: 2001-04-27T15:05:38 PANIC(300) z2 Startup exception Traceback (innermost last): File /usr/local/zope/Zope-2.3.2b2-src/z2.py, line 566, in ?

Re: [Zope-dev] Zope Server hanging :-(

Attached is a script that I just checked into the trunk to do analysis of the file generated by the -M log. It can help you figure out if there's a pattern to the hangs (whether it happens on a particular method, whether it happens at heavy load time, whether it happens at a particular time of day, etc.) Do you think you'd be willing to play around with it a little bit to try to discover a pattern?

Re: [Zope-dev] Re: BTreeFolder
Phillip J. Eby wrote: Now, what *I*'d like to know is what the bold new idea is, since it sounds like it's something even newer than the forward-chained-buckets-plus-conflict-resolution stuff that's already been released. It's simple, really. BTreeFolders play havoc with acquisition because every time you pass through them, looking for some name, they perform a lookup in a BTree. This wouldn't be an issue if it weren't for the fact that many sites use implicit acquisition heavily--I once measured 4500 lookups in a simple request to the management interface. But if the items stored in the BTree follow some simple pattern, we don't have to perform a BTree lookup for things that don't follow the pattern. The most useful pattern would be a string prefix followed by an integer, which would allow us to use an IOBTree (meaning integer keys and object values) for storage. Jim claims an IOBTree is faster. :-) So when scripts go looking all the way up the tree for the name REQUEST a hundred times (a common thing to do), the BTreeFolder can ignore it. The other cool idea he came up with is allowing the folder to decide what the ID of a new object is going to be so the folder can try to avoid conflicts with other ZEO clients. Many Zope applications use time stamps for IDs, but doing that can lead to frequent conflicts. Random IDs avoid conflicts. However, purely random IDs would cause all the buckets to be loaded in memory all the time, so Jim's third idea was to have each client increment sequentially from a random ID and move to a new random ID if conflicts ever occur. So, all things considered, you get faster access, fewer conflicts, and less RAM usage. Can't beat that. :-) Shane ___ 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 )

Re:[Zope-dev] Trying to set roles/permissions programmatically - Now I have a headache!
Hello Dieter! As you can see in my email (after the first paragraph), I did look through management interface and AccessControl/*.py Before writing to the list and annoying others with my little problems, I 1. try it myself (for a short time) 2. - search the mailing list archives - search all available docs: Guides, ZB, HowTos, ZQR - saerch zope.org (wikis) - try to see if there is a similar situation already solved (management interface, other products) 3. - try on my own again (found something useful), this time longer than on 1. And I have read chapter3 :-) Unfortunately, setting permissions programmatically has never been a hot topic for Zopistas (too easy to talk about?). What I was looking for was a way to get a hold of some sort of Permission object instance. After strolling the sources, I finally found out what this is (apparently) all about, and that I was looking for the wrong thing. (permissionEdit.dtml - Role.py's manage_changePermission - Permission.py's Permission.__init__) -- Here's the result, works alright for me: (Hey nuno! Hth, you asked for something like this on the list a month ago) -- def setRolesForPermission(ob, permission, roles, acquire): for p in ob.ac_inherited_permissions(1):# A name, value = p[:2]n if name==permission: p=Permission(name,value,ob) # B if acquire: roles=list(roles) else: roles=tuple(roles) p.setRoles(roles) return raise 'Invalid Permission', (The permission em%s/em is invalid. % permission) -- (ok, assigning a value (maybe lots of times) where it's only needed in one case is inefficent) A and B were the hints I missed when I wrote the last mail. So you really *do* run through all the permissions, get their names and check against your string parameter until you match. (Is this a must?) Then you *instantiate* a Permission. (see Permission.__init__(self,name,data,obj,default=None)) Yes, and setRoles (and acquisition setting) works like I expected, phew.

[Zope-dev] Permissions to change Acquire Permissions?
I was wondering if it would be possible for a new permission to be created, this permission would let (or stop) people from changing the Acquire Permissions check boxes found in the Security Tab. The reason I would like a permissions like this is that some users that need to give people permissions are exactly trusted. This means that they could change the acquire permissions and circumvent people with Manager or higher privileges. This type of permission could be very useful for zope to have but would most properly require changing of how permission changing is handled?

Hi, I need some help on the creation of a (dummy?) user object using Python. I am trying to test a zope product using ZUnit. I have been able to 'simulate' a request by using the makerequest.py module (Lib/Python/Testing). Here is how I used it: import makerequest app = makerequest.makerequest(Zope.app()) request = app.REQUEST Now, the REQUEST object does not contain any AUTHENTICATED_USER, and this causes me problem because my product is using the user object, in other words, the product can not be fully tested. So, is it possible create (or simulated) an AUTHENTICATED_USER in the REQUEST? if it is, then I'll like to know how. Thank for your time and help Cheers, Karim ___ 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 )
