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)

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

I created a ZClass subclassing CatalogAware and File. I added a property called text which is text indexed in a catalog. When a Word document is added, a method I created uses the wvHtml utility to convert the Word document to text and store it in the text property. It has kind of a kludgey implementation at the moment, mostly because I want to create a Python wrapper around the wv library, but it's documentation is sketchy and I have other priorities at the moment. It does work though and lets you search Word documents using a ZCatalog quite effectively (although it only works for Word docs). Check out wv at http://www.wvware.com/

Hi all, Please, forget my previous message! Next question : Is there an easier way for writing the following? <dtml-let position=sequence-item> <dtml-var expr="position+1">/<dtml-var count-CENTRE_NO> <dtml-let> This gives the sequence order of every record on the total amount of retrieved records. So far, this was the only way I could get it to work. Is there a better way (simpler) ? Thanks, Tom.

ZSQL methods do not pick variables up out of the name space because the possability of unintended collision with database variables is considered too high. So ZSQL forces you to be fairly explicit about which variables you are passing. --RDM -- __--__-- Message: 4 Date: Fri, 4 Aug 2000 21:58:47 -0400 (EDT) From: "R.

I wonder if you could put your content in a mountable storage and just periodically copy that storage down to the development machine, and similarly periodically copy the master storage (containing the ZClasses) up from the development machine. If your products are Python products you wouldn't even need a mountable storage. > Also, how would you see schema versioning > How could we for instance deal with > objects generated from a product if the product > schema changes ? Zope uses the __setstate__ method for handling this case in Python products. I think there's a howto somewhere but I'm not sure. If not you can find examples of calling it in the Zope sources. For ZClasses the objects get all their info from the ZClass, so you generally don't run into upgrade problems (though people have run into trouble with properties they have tried to delete hanging around on existing instances). --RDM -- __--__-- Message: 5 Reply-To: <Steve.Nicholson(a)yoursolutions.com> From: "Steve Nicholson" <Steve.Nicholson(a)yoursolutions.com> To: <zope(a)zope.org> Subject: [Zope] Zope on old hardware??

As far as I can tell from a quick scan of the source, the precondition is an object that is called just before the file object is rendered. It can raise an exception, in which case the object will not get rendered. I could swear I read that documented somewhere, but I can't find it.

A Vocabulary allows you to associate an arbitrary method of parsing input text into words for the purposes of cataloging and searching in text indexes. The default Vocabulary uses the original Splitter.c word parser, which is very English centric. --RDM -- __--__-- Message: 8 From: Dieter Maurer <dieter(a)handshake.de> Date: Fri, 4 Aug 2000 23:00:11 +0200 (CEST) To: zope(a)zope.org Subject: [Zope] Zope in single thread mode during DTML rendering A collegue of mine succeeded today to implement an infinite DTML loop.

Zope 2.1.6 Binary Distribution for Sparc Solaris 2.6 ZOracle DA, DCOracle, Oracle 8.1.6 After several minutes, Zope reported an "infinite recursion in document template" and the world awoke from its sleep.

SQL query template: .... <dtml-sqlvar "_[name]" type=string> .... reported: "missing input variable: _[name]" Of cause, I did not expect that such an input variable should be necessary and I suspected the DTML parser not to see the "..." around "_[name]". After analysis, the explanation was simple: SQLVar.render is a bit stupid in its error handling: try: expr=self.expr if type(expr) is type(''): v=md[expr] else: v=expr(md) except: if args.has_key('optional') and args['optional']: return 'null' raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name This error handling is only senseful for "type(expr) == type('')", i.e. for plain variable access. For true expressions, the original exception would be *much* more useful. In my case, unwrapping the "try ... except ..." produced "KeyError: FOLLUP_UP", an obvious type (FOLLOW_UP rather than FOLLUP_UP). Thus, the above exception handling should become: except: if args.has_key('optional') and args['optional']: return 'null' if type(self.expr) != type(''): raise raise 'Missing Input', 'Missing input variable, <em>%s</em>' % name I will put it into the collector.

Someone else already told you, that you must create a parameterless method (it need not necessary be named "PrincipiaSearchSource") that returns the files content. You may not need to keep the rendered version around but may be able to extract the plain text on demand. I think, there is a "word.dll" that provides access to MS Word from applications. Alternatively, you could control Word via COM.

For unknown (but strange) reasons, at least earlier Zope versions (up to 2.1.6), sometimes place the URL of the missing resource into an HTML comment.

Organization: Net Facilities Group *** http://www.nfg.nl From: gyst(a)nfg.nl (Guido A.J. Stevens) Date: 05 Aug 2000 14:22:30 +0200 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: <STRONG>Error Type: TypeError</STRONG><BR> <STRONG>Error Value: ('len() of unsized object', <class Shared.DC.ZRDB.DA.SQL at 845bd28>, None)</STRONG><BR>  when I try to edit the properties of an instance of my Zclass. Itamar's dtml is a bit too subtle for me to follow at this stage. Anyone know what's happening? I don't see any "<string>" in edit_propertiesForm, which is what triggers this traceback. -- jean --__--__-- Message: 24 From: "David Loeffler" <loefflerdavid(a)hotmail.com> To: zope(a)zope.org Subject: [Zope] Newbie question: referring to <dtml-call> documents Date: Mon, 07 Aug 2000 14:44:44 BST My site has a number of DTML Document objects which simply redirect the user to another site. These are all created automatically as clones of each other. The text of the document is simply <dtml-call "RESPONSE.redirect(dest)"> and dest is a property automatically set on creation. I need to provide a simple form to allow users to edit the value of this property, so I have to retrieve the current value of the property. However, whenever I try to get hold of this with anything like <dtml-var "_[objId].getProperty(dest)"> (objId is the id of the document) it simply redirects the user immediately to the site named by dest. How do I just get the property value as a string?

I now have to move the Zope server to it's final location, which is a Windows 2000 server (it's not my choice ;-( I am trying to get the user authenticated based on his IP address to allow everybody on the subnet we are here to access the Zope server, but not other IPs. This works fine except it is really slow (about 5 seconds to go to an object to start downloading). I've tried it on a clean Win2k box to check if I had a problem with my configuration, but it didn't change anything. Here are the basic operations I did. First create a local role "test" in / that has the same authorization as anonymous. Then disable any authorization for this Anonymous user. Create a user in acl_user which don't have a password but has a domain entry 192.168.0.* and the role "test". Now when I connect from the 192.168.0. subnet, I have access to the Zope server, but it is very slow to answer. When I add a user that has to log in (password instead of IP check), it goes much faster. I am using Zope 2.2.0 with the built-in Medusa web server. As I am with the Win2000 questions, is there a way to configure IIS to behave like Apache an the rewrite rules? Thank you for your help.

ImageFile objects do not (like ZODB stored Image objects) generate an IMG tag when called. Image object, when called, generate an IMG tag that points the browser to the correct address to retrieve tha actual image. With an ImageFile object, you need to construct the tag yourself. If this class has an instance foo, with this ImageFile attribute chooser, and the instance foo is stored in the root of your Zope ZODB, you need to point the browser to http://yoursever/foo/chooser. So your DTML needs to generate the following HTML: <img src="http://yoursever/foo/chooser"> I don't know enough about your DTML, but if it is another attribute of the same class, you could use one of the URLx REQUEST variables or something to construct the URL for the image. Also, absolute_url() called on the foo instance may also work for a base URL. Hope this helps. -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ | ZopeStudio: http://www.zope.org/Products/ZopeStudio ----------------------------------------------------- --__--__-- _______________________________________________ Zope maillist - Zope(a)zope.org --__--__---- End of Zope Digest
