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??

Is this a viable proposition for hosting, I'm not anticipating millions of hits?? I realise it's not the fastest thing in town but for a good price it gives me a RAID drive for reliability. What sort of load will it handle, hits etc? Does Zope take advantage of the Dual processors? What improvement is there over one processor? This box can be upgraded to P166's what would be the improvement? Is anyone out there running Linux on Dell EX590-2, can I expect lots of problems or easy to set-up?

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. Someone should submit a doc patch for the API help pane. I'd do it, but I haven't gotten around to learning how the help system works yet so I don't know what file to patch <grin>. --RDM -- __--__-- Message: 7 Date: Fri, 4 Aug 2000 22:15:26 -0400 (EDT) From: "R.

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. That happens ... However, during this loop, Zope did not respond to any request. Effectively, it was in single thread mode. 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. I was unable to reproduce this at home, though: Zope 2.1.6 Source Distribution on Linux 2 No database connections. Hugh, I have been lying: I just removed the "-D" from the Linux start script, and Zope blocked during the infinite loop. The behaviour is not related to the "-D" set or unset. It just blocks sometimes and at other times, it does not.

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.

Almost surely, the "in" tag does not call a callable object (because it does not expect, they could be callable). You, therefore, get the method itself. It is identical for all records.

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. Therefore, you will not see it in rendered problem report, only in its HTML source. Thus, follow the hint: tell your browser you want to see the HTML source of the error report.

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.

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

QuickStart
by Chris Withers 07 Aug '00

Hi, Small niggle... Isn't it time the QuickStart bit the dust? It's quite strange seeing references to Principia and Acqueduct in Zope 2.2 ;-) Doesn't the Tutorial replace this quite comfortably? Just a thought, Chris

Just a simple question. According to Amos' How-To: Thread Safety in Zope 2, what is mutable global or shared variables?? What is the scope of such global variables? Zope wide? module wide? If global variable is not permitted, how can I approach thread programming in Zope? Without global variables, how can I control threads? Please kindly help Regards, Nicholas Lo

Newbie question: referring to <dtml-call> documents
by David Loeffler 07 Aug '00

07 Aug '00

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?

RE: [Zope] Python Method question
by Chris McDonough 07 Aug '00

07 Aug '00

Do you mean you want to use a Python Method (in the sense of a methodish object instantiated from Evan Simpson's Python Method Product) from a Python Product? You *should* be able to call it by getting a hold of it through acquisition or by otherwise getting a hold of an object in the ZODB and traversing from it. > -----Original Message----- > From: entropia [mailto:entropiamax@jazzfree.com] > Sent: Monday, August 07, 2000 3:20 AM > To: zope(a)zope.org > Subject: [Zope] Python Method question > > > I hava a question regards Python Method: How can I > import a Python Method from a Product module? > > > _______________________________________________ > 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 ) >
