I did not read this How-To. Thus, be careful with my explanation. A mutable object is one that can change its value over time. E.g. a list is mutable (you can "append", "insert", "delete" elements) while a tuple is not. If several threads concurrently access a mutable object (or a mutable binding, i.e. a name (variable) is bound to different values over time), results can be quite unpredictable. Usually, you would use a synchronization mechanism to control access to objects. See the Python modules "thread" and "threading" for functions available for this purpose. > If global variable is not permitted, how can I approach thread > programming in Zope? Without global variables, how can I control > threads? You can use global variables -- provided you know what you do and ensure proper synchronization. You may want to look at "ZODB.Transaction.get_transaction" to learn how Zope itself manages its transaction context in view of serveral threads. Dieter PS: I do not like MIME messages in this list. The list software strips MIME headers and my mail reader is therefore unable to decode the message.

"_[xxx]" executes (calls) the retrieved object, if possible. In your case, execution calls "RESPONSE.redirect". You need "_.getitem(xxx)" instead of "_[xxx]". This only retrieves and does not call the object. Dieter

I expect you to have a misconfigured selection property somewhere. Dieter

PTK Member-Folder Object Properties (phew!)
by David Riggs 07 Aug '00

07 Aug '00

For each member in the Portal ToolKit, a folder is created in the folder 'Members', i.e: ZopeRoot/Portal/Members/member_name I've created a ZClass called Customize that has several properties, and I've added an instance of Customize (and called each instance Customize) in each member's folder. i.e.: /Portal/Members/member_name/Customize What I need is a way to access the value of these properties for any given member that is logged in at the moment. In other words, I can do this... <dtml-var "_.getattr(Members.member1.Customize, 'some_property')"> and get the value that I need for member1. I want the equivalent of replacing 'member1' with AUTHENTICATED_USER.getName()...I tried substuting it in and building a string with it, but that causes getattr to complain about strings not having the needed property. Any ideas on how to make this work, or ideas on how to do it a similar (or even completely different) way?

Success! ZPoPyDA 0.6.1 works!
by Stephen Nosal 07 Aug '00

07 Aug '00

First, I would like to say thanks to everyone, who gave me a hand with this, especially jpenny(a)universal-fasteners.com. I learned a lot, and I am more comfortable with my system than ever. Below is a little note and question for Federico, who provided the patch that got the whole thing going again. Thanks again, - Steve Federico - This is the output of my compilation of ZPoPyDA 0.6.1 Two questions: 1) It looks for README before it creates it. 2) Make appears to do nothing.

Can't add objects
by Maarten Engelen 07 Aug '00

07 Aug '00

I've installed Zope on an account at a hosting company. Zope runs perfect, but I can't add any new objects. I can edit existing object without any problems, but adding is impossible because of the 500 error which the server gives. Does someone have any idea what could cause this problem?

RE: [Zope] Authentification with the SAM of NT (Security Account Manager)
by Chris McDonough 07 Aug '00

First, there is no such work as authentification. :-) OK, now that I got that off my chest, take a look at jcNTUserFolder (http://www.zope.org/Members/jephte/jcNTUserFolder) smbUserFolder (http://www.zope.org/Members/mcdonc/smbUserFolder) and Tres Seaver's Integrating Login Manager with SMB (http://www.zope.org/Members/tseaver/LoginManager_and_SMB) Any of these will work, depending on your situation. jcNTUserFolder is best if your Zope server runs on Windows. smbUserFolder or Tres' howto work best if your Zope server runs on anything else. > -----Original Message----- > From: Vincent [mailto:vinc.del@wanadoo.fr] > Sent: Friday, April 07, 2000 2:10 PM > To: [Zope Org] (E-mail) > Subject: [Zope] Authentification with the SAM of NT (Security Account > Manager) > > > Hi, > > Does anyone know if Zope allows authentification of a user > with the SAM > (Security Account Manager) of Windows NT ? > > I mean : > > -> The user types his login/password > -> and then, zope asks the SAM if this user does exists (or not). > > Thanks. > > Vincent > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

Zope Crashes (memory corruption) resolved
by Dieter Maurer 07 Aug '00

07 Aug '00

Several times, I reported to the list about memory corruption problems with Zope 2.1.6 ZOracleDA 2.1.0 DCOracle (as of August 1999) Oracle 8.1.6 Sparc Solaris 2.7 This issue is finally resolved: The memory corruption occurs inside the Oracle 8 Client Library call OCILogoff. As * OCILogoff is only called, if DCOracle is compiled with -DORACLE8 * -DORACLE8 is only needed for Oracle 8 LOB support * the DCOracle LOB support does not work for Oracle 8.1 anyway we could simple recompile DCOracle without -DORACLE8 to get rid of the problem. As Matt (mailto:matt@digicool.com) reported, the problem is also avoided with a newer DCOracle version (1.3.1b1). Dieter
