KeywordIndex Error and Startup Exception
by Bert Vanderbauwhede 04 Feb '04

04 Feb '04

Hi, Last night, the Zope service on one of my servers has crashed. When I looked into the $STUPID_LOG_FILE, I found that a whole bunch of errors had happened during the day, first this one: ----- 2004-02-03T12:49:18 ERROR(200) KeywordIndex unindex_object tried to retrieve set 'wauw - systeem' from index Subject but couldn't. This should not happen. ----- And next several ones like this: ------ 2004-02-03T13:59:03 ERROR(200) KeywordIndex unindex_object could not remove documentId 1986485462 from index Subject. This should not happen. Traceback (innermost last): File /usr/src/redhat/BUILD/Zope-2.5.1-src/lib/python/Products/PluginIndexes/common/UnIndex.py, line 168, in removeForwardIndexEntry (Object: Subject) KeyError: 1986485462 ------ I have cronjob running that creates a backup and packs Data.fs at 21:00. This involves stopping and starting Zope. According to $STUPID_LOG_FILE, this worked well. But later I got this: ------ 2004-02-04T00:00:26 PANIC(300) z2 Startup exception Traceback (innermost last): File z2.py, line 497, in ? File <string>, line 1, in ? File /usr/src/redhat/BUILD/Zope-2.5.1-src/lib/python/Zope/__init__.py, line 37, in ? File /usr/src/redhat/BUILD/Zope-2.5.1-src/lib/python/ZODB/FileStorage.py, line 213, in __init__ File /usr/src/redhat/BUILD/Zope-2.5.1-src/lib/python/ZODB/lock_file.py, line 33, in lock_file StorageSystemError: Could not lock the database file. There must be another process that has opened the file. <p> ------ This morning, after finding out, I could just restart Zope, as if nothing had happened. I had the impression that about 20 documents had disappeared, so I restored Data.fs from the backup I made yestarday evening. Questions: 1. What were the KeywordIndex errors all about? Should I get worried? 2. Were the KeywordIndex errors the cause of the crash this night? I use Python 2.1.3 and Zope 2.5.1, on RedHat 8.0.

Is there an accepted idiom for raising an exception via tal? Or, do I need to script that? What I'm trying to do is raise a NotFound exception under certain conditions. Thanks!

Pass Variable to ZSQL from HTML page REQUEST object.
by RI Dunfey 04 Feb '04

04 Feb '04

Hi, I have a html page with the following dtml tag: <dtml-in get_names> <dtml-var NAME></a> <BR> </dtml-in> When the page loads it calls the zsql that returns NAME and JOB. So I can access these from the request object, as above. However, how would I pass a variable to the zSQL? The value of the variable I want to pass is stored in the request object when the page loads. I have looked in the book but this is not explained? In the example above, I would wish to pass a vaiable to the get_names SQL? Any help appreciated, Rob

Proxy roles
by Marcin Wudarczyk 04 Feb '04

04 Feb '04

I have a question concerning proxy roles. The problem I have encountered is that when I grant a proxy role to a script, other scripts and templates called from that script do not posess that role. Is it an error, should it be like that or am I doing something wrong? Marcin Wudarczyk http://mar.prv.pl

popen2, popen3, popen4 and Zope
by Dennis Allison 04 Feb '04

04 Feb '04

The popen libraries don't seem to function properly when used from a Zope External Method or product. I use the standard idiom -- i, o = os.popen2( cmd ) i.close() res = o.read() but Zope seems to hangs on the read whenever cmd is anything of any complexity, for example, a shell script that fires off a python instance that detaches itself and then initiates another insance of Zope. Is the problem a threading issue? Is there a preferred mechanism for spawning a process?

Dynamic Reference, mixing ZOPE and SQL
by Ryan T. Bard 04 Feb '04

04 Feb '04

I have a sequence of code that is monstrously inefficient and am looking for help. I am storing the id tag of an ExtFile object in my sql database along with other information and am now creating a page that displays info from the database record by record. For each record displayed, I also want to pull the file size from the Zope side of things. The method which works is something like this: <dtml-in my_query> <dtml-comment> query returns file_id amongst other values </dtml-comment> <dtml-with files> <dtml-in "objectValues(['ExtFile'])"> <dtml-if "id == file_id"> <dtml-var size> </dtml-if> </dtml-in> </dtml-with> </dtml-in> With a 1000+ ExtFile objects in the "files" folder, the search is ok for just one record being displayed; however, if this page is displaying all 1000+ files based on the SQL records, then for each SQL record returned it is iterating through the entire contents of my files folder, and is very slow to resolve. What I am looking for is a way to say: <dtml-in my_query> <dtml-comment> query returns file_id amongst other values </dtml-comment> <dtml-var files.file_id.size> //where file_id is a dynamic ref // not the id itself </dtml-in> However, I don't know a good method for doing a dynamic reference here, such as the following which fails: <dtml-in my_query> <dtml-comment> query returns file_id amongst other values </dtml-comment> <dtml-with files> <dtml-in "objectValues(['ExtFile'])._['file_id']"> <dtml-var size> </dtml-in> </dtml-with> </dtml-in> I am just extrapolating from things like using "sequence-item" in an expression changes it over to "_['sequence-item']". Not even sure the dtml-in would work the way I want, but the idea is there. Maybe to effectively use something like this to reference an object I explicitly know: <dtml-in my_query> <dtml-comment> query returns file_id amongst other values </dtml-comment> <dtml-var "files._['file_id'].size"> </dtml-in> The above approach throws unauthorized exceptions, so obviously not the right way to go about it. Anyone know the correct syntax for achieving this both inside a python expression and/or as a direct dtml expression? Thanks, -- Ryan T.

RE: [Zope] URLs expose information which we'd like to hide
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 04 Feb '04

04 Feb '04

Not to mention that if the originator of the link is a web page, the information is in the html code, even if using a post. Otherwise, in Zope, using GET or POST works equally well. Unless you do something really special, you can actually switch between using one or the other without changing code or anything else. J.F. -----Original Message----- From: zope-bounces(a)zope.org [mailto:zope-bounces@zope.org]On Behalf Of Jamie Heilman Sent: Wednesday, February 04, 2004 3:23 PM To: zope(a)zope.org Subject: Re: [Zope] URLs expose information which we'd like to hide Dennis Allison wrote: > The parameters passed by GET and, to a lesser extent, the URLs themselves, > represent a security issue in one of our systems.

I suspect there are all > sorts of hidden gotchas. Using POST to send query params instead of GET is trivial. The only gotchas are that using very few browsers handle redirecting POST transactions correctly.
