Description David D'Acquisto 2010-11-07 08:35:42 UTC

I having a similar error like 11292 bug but with Oracle 10g Express Edition. The error is:

function.unserialize Error at offset 0 of 48 bytes in /var/www/mediawiki-1.16.0/includes/BagOStuff.php

I just installed a fresh mediawiki on Redhat Enterprise Linux using Apache 2.2.17 and PHP 5.3.3. How should I proceed with debugging. Has anybody a hint or idea?

Thanks for your comments.

Oops I missed to add the line number where the error occurs. It is line number 437.

Comment 2 Bawolff (Brian Wolff) 2010-11-07 21:55:40 UTC

Switching component to DB.

Comment 3 Jure Kajzer 2010-11-08 15:07:16 UTC

Could you attach exception details http://www.mediawiki.org/wiki/Debugging

... and if possible the procedure to recreate that situation.

Comment 4 Jure Kajzer 2010-11-09 08:29:52 UTC

Created attachment 7805 [details]
blob temporary descriptors added +en/decodeBlob

Could you please try applying this patch ...

Comment 5 David D'Acquisto 2010-11-09 22:00:39 UTC

I tried the patch but without success. If you want you can try to reproduce the error with the following procedure:

Install Oracle Enterprise Linux 5.5 (free)
Install Oracle Express Edition
Install Apache 2.2.17
Install PHP 5.3.3
Untar Mediawiki 1.16
Execute maintenance/ora/user.sql
Install Mediawiki with Parameters like ...

$wgDBtype           = "oracle";
$wgDBserver         = "localhost";
$wgDBname           = "//loclahost:1521/XE";
$wgDBuser           = "USERNAME";
$wgDBpassword       = "PASSWORD";

and then you should see it on every page after successful installation. As I am not anymore highly interested in this issue take your time in fixing it. I hope someone else will contribute to the solution.

Bye, David

Comment 6 David D'Acquisto 2010-11-10 21:31:29 UTC

Jure, I can confirm that applying patch and executing ...

SQL> truncate table objectcache;

Table truncated.

SQL>

the issue apprears to be solved. You can mark this bug as fixed. :-)

Comment 8 Roan Kattouw 2010-11-11 13:15:11 UTC

Bugzilla is not a support forum. Don't reopen tangentially related to ask for help.

If you need help installing MediaWiki, ask on IRC (#mediawiki on irc.freenode.net) or on the mediawiki-l mailing list.
