Zope 2.2 under Debian (Woody) broken?
by Pedro I. Sanchez 06 Aug '00

06 Aug '00

Hello, I installed zope 2.2.0-1 from the Debian (Woody) distribution. No problems are reported during the installation but when I try to access http://localhost:9673/ I get the following error: Zope Error Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: unexpected keyword argument: validated_hook The same happens when I try to access the management menus. Is the Woody package broken? Any ideas? Thank you, -- Pedro

It would seem to be broken.... you might want to contact the package maintainer. I think it's Glyph Lefkowitz? > -----Original Message----- > From: Pedro I.

DA threading issues (was: server instability: ZODB corruption?)
by gyst＠nfg.nl 05 Aug '00

05 Aug '00

If I'm running current stable versions of Zope and Zope-MysqlDA, do I need to consider threading issues or are these safely abstracted away in the DA? "Luis Cortes" <LCortes(a)IMEME.NET> writes: > It may just be the version of Zope you have ( with regard to the Thread > problem ) there exists a version of zope that was known to cause the thread > death problem. You might want to check the patches or upgrade to a good > version. I'm running the Debian frozen release, i.e. 2.1.6 with security patches. Do you have any specific references on the thread problem? I find nothing on it in the changelogs I've found. Do I need to go to 2.2.0 for this? A seach on 'threading problem' turns up a hornet's nest of deep technical shit. Most of those mails are a year old, is this still an issue? As a developer, do I need to understand threading issues when developing database accessing products, or may I safely assume that threading, locking and transaction semantics are handled between the Database Adapter and Zope itself? I found a mail that says I should run Zope single-threaded when using MySQL: http://lists.zope.org/pipermail/zope/1999-July/006487.html Checking my installation, I find I have no threading option activated, which means I'll be running the default number of 4 threads. What will my server performance look like if I reduce this to 1 thread? Not that I'm having such a wonderful performance now, having my pager go off every hour :-( Is there a way to allocate different threads to different SiteRoot virtual websites, so I can lock a single site in a single thread but let my installation as a whole still retain some multi-threading performance? :*CU# -- *** Guido A.J.

LoginManager and ZPatterns - Sparse Install Docs, Help.
by Darin Lee 05 Aug '00

05 Aug '00

Zopistas, Maybe I'm making this harder than it needs to be. I want to set up a membership system for the site I am developing with Zope. I do not want to "restrict" any part of the site - instead I want a user to login (at their convenience) and then extend the "menu" options based on their group membership. If a user is not logged in - no problem, they just won't be able to view the advanced options - they'll still be able to surf the site (I want to maintain my user list in an external database as well). What is the best tool in Zope to accomplish this? After searching the site, I find there are several products - ACL Users, GUF, and LoginManager. Is GUF deprecated (The intro tends to give me this feeling)? Is LoginManager the way to go? It also appears GUF is more tailored toward restrictive authentication (I've already perused the "Using GUF with an SQL Database" how-to). I want a user to login (via HTML form/cookie) whenever they like, and get presented with additional menu options (based on their AUTHENICATED/GROUP status). Not have them try to access a "restricted" page (or type "manage") and get a basic authentication login box to get in. As far as LoginManager itself is concerned, I assume it requires ZPatterns. However, the Zpatterns install instructions are *very sparse.* How do I get the thing set up? Here's verbatim from the ZPatterns docs: ----- After unpacking the ZPatterns product, you will need to build this [c] >extension using the included Setup file in the ZPatterns directory. ----- How do I use the "Setup" file?? With the command "python Setup"? It doesn't say *how* to use it. ----- Please follow the standard procedures for building a Python module on your platform. (On Unix-ish systems, this usually consists of copying a Makefile.pre.in to the directory, then doing a make -f Makefile.pre.in boot >followed by make. ----- What are these standard procedures?? I built Python itself with "configure|Make|Make install". Where do I get this "Makefile.pre.in" file in the first place, from my Python src/build directory?? Correct me if I'm wrong, but there's usually some kind of script file to run that get's things going, or a "configure" script. I find none of this in the lib/python/Products/ZPatterns directory after I untarred it. So, I'm basically stumped. It doesn't appear GUF will do what I need, and I have failed on multiple attempts to get Loginmanager/ZPatterns installed. If someone could point me in the right direction on this I sure would appreciate it. Thanks much, -Darin Lee

Hi, I'm having problems with adding Properties to a ZClass propertysheet. I always get an IndexError (no traceback, sorry) when I've hit the Add button. There are no special characters in the name ('Daten'). Does someone know what could be the problem? Thanks in advance Eric

So true, the solution is to define an __init__ class in the brain class, then use that to populate "self". class PackageEvent: """Package Event Pluggable Brain""" def __init__(self): """initialize""" self.__dict__['eday'] = self.eventday() def eventday(self): return DateTime(apply(time.mktime,self.eventtime.tuple()[:3]+(0,0,0,0,0,-1 ))) Now 'first-eday' works.

riddle me this Batman, coded copy/paste syntax?
by Darran Edmundson 05 Aug '00

05 Aug '00

The Zope quick reference lists the following methods for the stock folder object: manage_copyObjects(self, ids, [REQUEST, RESPONSE]) manage_cutObjects(self, ids, [REQUEST]) manage_delObjects(self, [ids, REQUEST]) manage_pasteObjects(self, [cb_copy_data, REQUEST]) For the life of me I can't get copy|cut and paste to work even for the simplest of examples. I've tried snippets like the following (embedded within a DTML method in a folder) but to no avail: <dtml-call "manage_copyObjects(['subobjectid']"> <dtml-call "manage_pasteObjects()"> <dtml-call "manage_copyObjects([_['subobjectid']])"> <dtml-call "manage_pasteObjects()"> Can someone shed some light on my misunderstanding? Cheers, Darran.

Using MailHost with an SMTP server that wants authentication
by Jean Jordaan 05 Aug '00

05 Aug '00

Hi Zopers Looking at the attributes of the dtml-sendmail tag, I don't see any way of conveying authentication data to the smtphost. Our setup here (using Exchange) requires a username/password to send. Any way of coping with this? -- Jean Jordaan -- technical writer -- Mosaic Sofware

server instability: ZODB corruption?
by gyst＠nfg.nl 05 Aug '00

05 Aug '00

I'm hunting down an arcane problem in one of our Zope sites and find myself hitting new and wildly diverse problems every day. I hope somebody can point me in the direction of some solution strategies. Main suspect is a corrupted Data.fs.in file. How can I audit and repair it? problem A: access denied vs. KeyError ============================ For starters, we built a website with a lot of custom programming. I created the NFGnav product http://www.zope.org/Members/gyst/NFGnav and my partner built a collection of ZClasses. All this was Tested And Working Fine (TM). Since some weeks, part of the site gives an 'access denied' error. We had to shut down that subtree. Strange thing is, it also gives access denied for the manager/owner logins of the site - that's me and I really have access to everything. What is even stranger, is that when I logon as superuser, I get a KeyError instead of an access denied error. => Question: which parts of zope would be prone to denying access to a privileged user, while generating KeyErrors for the superuser? problem B: hanging zope thread zombies all zope sites ======================================== While debugging this problem, I found a strange correlation with another problem we're having: zope threads consuming 99.9% CPU. Now and again, a zope thread hangs. All zope sites are dead. I have to not only restart zope; I have to stop zope, restart apache, and start zope again to get rid of the hanging thread and get the zope sites alive again. As soon as I start digging around in the buggy site, the number of thread crashes jumps up. In combination with the problems we're having with that site itself, this suggests two possible causes: 1) ZODB curruption. We've had a complete server crash 3 weeks ago and it is quite possible the ZODB isn't 100% healthy. In my zope installation I found a utility 'bbb.py' to audit data storage files. Alas, it is of no use: | zeno:/usr/lib/zope/utilities# python bbb.py /var/lib/zope/import/www.intratuin.nl.zexp | | The input file is not a ZODB 2 database file. | This script only works with ZODB 2 (BoboPOS) data or export files. => Question: is there another utility for checking and repairing object stores? 2) Another possible cause would be an infinite loop in one of our custom scripts. To try and debug this I wanted to import a copy of the offending site into one of our testlab machines. However, on importing the zexp file I got: Error Type: TypeError Error Value: ('len() of unsized object', <class Shared.DC.ZRDB.DA.SQL at 845bd28>, None) <!-- Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_importObject) File /usr/lib/zope/lib/python/OFS/ObjectManager.py, line 478, in manage_importObject (Object: ApplicationDefaultPermissions) File /usr/lib/zope/lib/python/ZODB/ExportImport.py, line 284, in importFile TypeError: (see above) I get the same error if I export another part of our production zope installation and try to import it to another test machine. Which points back into the direction of a file corruption again, doesn't it? => So, what can I do about it? :*CU# -- *** Guido A.J.
