[Mediawiki-l] Problems upgrading from version 1.4 to 1.[89].x

10 May 2007

Hi,
I have to use a mediawiki from one host to an other and want
to use the chance to upgrade the old fashioned 1.4 version
(I'm using the Debian packaged version).  The new machine
is based on SLES9.  While I'm a Debian developer personally
circumstances require to use this system and I mention it
here to make clear that while I'm an experienced Linux user
I'm completely new to SLES - perhaps that matters.
This new hosts has the following components:
$ mysql --version
    mysql  Ver 14.12 Distrib 5.0.26, for pc-linux-gnu (i686) using readline 5.0
as RPM from "anywhere"
$ > php --version
    PHP 5.2.0RC4 (cli) (built: Oct 30 2006 13:25:26)
    Copyright (c) 1997-2006 The PHP Group
    Zend Engine v2.2.0, Copyright (c) 1998-2006 Zend Technologies
perhaps from source or binary distribution to /usr/local/bin while
$ /usr/bin/php --version
    PHP 4.3.4 (cli) (built: Mar  2 2007 21:34:32)
    Copyright (c) 1997-2003 The PHP Group
    Zend Engine v1.3.0, Copyright (c) 1998-2003 Zend Technologies
resides in parallel on this machine.
Moreover the former admin has installed
MediaWiki 1.8.2 (from October 13, 2006)
under /srv/www/htdocs/wiki.  It would be no problem for me to replace
this installation by tha latest stable mediawiki version if this is
advised and would help in the problem, provided that the LDAP patch
which was manually added will work as flawlessly as in this installation.
I noticed that the former admin did not set an mysql passwd and
you might call me paranoid but I did
/usr/bin/mysqladmin -u root password 'passwd'
(Perhaps this is the source of my trouble.)
I mysqldumped my wikidb and rsynced it to the new host and inserted
it via
echo "CREATE DATABASE wikidb;" | mysql
    cat wikidb.dump | mysql wikidb
Now I found in the docs that an upgrade from mediawiki 1.4 to 1.5
requires to change the encoding to UTF8 which can be done using
<mediawikidir>/maintenance/upgrade1_5.php
Because this script failed connecting to the database I (as a
complete PHP beginner) did some print-Hello-World debugging and
found that the root password is not given problem, that I was
able to solve via

while "Hack 1" enabled me to run the script at all and Hack 2
just skips a step that failed for reasons I can not imagine.
After this the script runned kind of successfully.  I have
no idea at all why the root password was
1. needed at all if $wgDBuser and $wgDBpassword was given in
      ../LocalSettings.php
2. not read correctly after even adding
      $wgDBpassword = $wgDBadminpassword = "passwd";
      in ../LocalSettings.php which I tried in a second step.
Anyway I tried to continue with
$ php update.php
    MediaWiki 1.8.2 Updater
A connection to the database could not be established. Check the
    values of $wgDBadminuser and $wgDBadminpassword.
which smells like the very same problem with the missing password and
I tried something like "Hack 1" again and patched the root passwd directly
into the code.  This at least helped a little bit:

Well, now I decided to stop this dirty patching and ask for professional
help here on this list.  Can anybody enlighten me what might went wrong

Kind regards and thanks for any help
