Database Corruption - Please HELP
by Ze Octavio 20 Jul '99

20 Jul '99

Hi all After a hard day of work in Zope yesterday, I arrive today and receive the error message about database corruption. I know that we can truncate the Data.bbb in the address of the record corrupted, great. And I did it in that way: perl -e 'truncate "Data.bbb",4672086' And whe I try to open the Data.bbb again, all is gone ! Only the default Data.bbb was restored, all my data is gone. The users, everything. What is the right way to truncate the Data.bbb please. -- Ze Octavio -- Hiperlógica <http://hiper.com.br> Automação de web-sites | Web-site automation São Paulo | Brasil | Fone: +55-11-251-4894

The other issue is simply that unless the vendor supplies an ODBC driver layer for your platform, you're still screwed. The only thing ODBC helps with is that you won't need to write a python DB-SIG compliant interface to a DB for which you have an ODBC driver. If you have some wierdo database that only provides an ODBC interface, then it will be useful - otherwise? meh. With the exception of DB2, almost every database I can think of has a mostly-portable DB-SIG compliant interface now. Well, ok, I think the msql one might still be a tad weird, but hey, unless someone's done something drastic, there's parts of that code that are 4 or 5 years old. Until the mxODBC license changes, that's also possibly an issue for people, too... Anthony.

Quotes cause Zope to *evaluate* a Python expression. In this case, 'sequence-even' looks to Python like 'sequence minus even'. What you want is just . Or, if you want to access that value in an expression, try . The '_' namespace can act like a mapping to all of these DTML variables that are illegal in python expressions. -Michel > shaded line code > ... >  > ... > unshaded line code > ... >  > > I can submit this to Zope no problem, but when I go to view > the page, I get > the standard error message with this in the source: > >  > > The error is generated by the line with the IF statement, as > I've verified > by changing to to test a different expression.

Sequences and SQL
by Sean McMains 20 Jul '99

20 Jul '99

Ok, now that I can get data into a database, I'm working on getting it out again. A simple table works fine, but I'd like to add alternate-line shading. This is what I'm trying:   ... shaded line code ...  ... unshaded line code ...  I can submit this to Zope no problem, but when I go to view the page, I get the standard error message with this in the source:  The error is generated by the line with the IF statement, as I've verified by changing to to test a different expression. I expect that I'm bumping into something syntactical, but can't figure out how to fix it! Help from you more experienced Zopers is appreciated. Thanks, Sean McMains

hi! i want to configure apache so zope starts at / and mailman starts at /mailman/ and /pipermail/. now i have the problem that /mailman/ and /pipermail/ are parsed by zope's rewrite rule and not aliased and script-aliased like they should be. anybody got a clue how to solve this problem? ciao, basti --------------------------------------------------------------------- sebastian f. luehnsdorf beehive elektronische medien gmbh --------------------------------------------------------------------- http://basti.beehive.de http://www.beehive.de mailto:basti@beehive.de mailto:service@beehive.de fon: (+49 30) 84 78 20 fax: (+49 30) 84 78 22 99

This will be the case in the first beta release, assuming I don't trip up and kill myself before the end of the week. It will use the same algorithm the binary releases use. Additionally,the file will store the password in SHA-1 format, which eventually will propagate into the rest of the system (more on this later when it's been smoothed out). This does mean that most likely WebDAV won't work with the superuser account, but then you shouldn't be using the superuser account, right? :-) BTW, changing the name is simply obscurity, and well, that won't fly.

This is to > include GUI support for KDE." After some talking, I'd say our position vis a vis ODBC on UNIX is that it's simply not a good solution for application servers. ODBC real value lies in the client side, and on Windows NT, where often it is the easiest (or only) solution. On UNIX, all database vendors ship native libraries (except Microsoft, but don't go there ;-), which are substantially better choices. Some "swag" looks, ODBC for Oracle, for example, is 1/10th the performance level of the native OCI level interface, so why would you use this in your application server? This is a good project for the community, but I hazard that we have no resources to dedicate to ODBC/UNIX integration.
