Wiki instances

The main wiki lives here:

/srv/www-sugarlabs/wiki/ 

Except for trivial changes, work on the wiki should be carried on in the wiki-devel instance, then moved to wiki-testing for feedback before putting it into the production instance.

Note: The devel and testing wikis share the same page database, but have separate server configurations.

Sometimes the devel and testing instances contain interim work performed by various wiki helpers. Do not sync changes blindly to the production wiki!

Before overwriting the page database, please

• observe http://wiki-devel.sugarlabs.org/go/Category:Under_construction
• announce the plan on systems@ and to any collaborators who have signed their 'Under construction' pages in the template (such as by using the 'E-mail this user' link in the sidebar for the wiki user's page, even when it is a red link or not yet created).

Creating a Local Labs wiki

• Add a group for the wiki (vigr)

cd /srv/www-sugarlabs
cp -a co.sugarlabs.org pe.sugarlabs.org
chown -R icarito:sugarwiki-pe pe.sugarlabs.org
cd pe.sugarlabs.org/wiki
rm -r images/*
vim LocalSettings.php
vim SecretSettings.php

• Create apache virtual host:

 cp -a /etc/apache2/sites-available/pe.sugarlabs.org /etc/apache2/sites-available/ar.sugarlabs.org
 vim /etc/apache2/sites-available/ar.sugarlabs.org
 a2ensite ar.sugarlabs.org

• Create DB with some clever trick. I reused config/index.php to setup a new MediaWiki instance and then I've thrown away the generated LocalConfig.php:

 mv LocalConfig.php LocalConfig.good
 cp -a /srv/www-sugarlabs/co.sugarlabs.org/config .
 (go to http://ar.sugarlabs.org/wiki/config/index.php)
 rm -r config LocalConfig.php
 mv LocalConfig.good LocalConfig.php

• Create tables for OpenID:

mysql -u root -p pe_sugarlabswiki < extensions/OpenID/openid_table.sql

Installation

Our MediaWiki instances are installed from git to allow easy rebasing of our changes on upgrades.

git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git wiki-devel
cd wiki-devel
git co -b REL1_19 remotes/origin/REL1_19
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions.git extensions-all
cd extensions-all
git submodule update --init
cd ../extensions
# for each needed extensions
ln -s ../extensions-all/EXT

For the full details on this installation method, see http://www.mediawiki.org/wiki/Download_from_Git

SVN Upgrade notes

THESE INSTRUCTIONS COVER SVN-BASED INSTALLATIONS -- THE PROCEDURE NEEDS TO BE RETHOUGHT FOR GIT

We update our MediaWiki instances by simply pulling from the remote git repo and then switching to a different stable branch:

git pull
git co -b REL1_xx remotes/origin/REL1_xx

Because the "extensions" directory comes from a different repository, we need to take care not to confuse Subversion's little mind when it sees it. Hence, we keep around a copy of the original extensions directory from the main repository.

mv extensions extensions.keep
mv extensions.orig extensions
svn switch http://svn.wikimedia.org/svnroot/mediawiki/branches/REL1_16/phase3
mv extensions extensions.orig
mv extensions.new extensions
cd extensions
svn switch http://svn.wikimedia.org/svnroot/mediawiki/branches/REL1_16/extensions
cd ..

Now run update scripts:

cd maintenance
php update.php

In the case of Local Labs wikis the correct command for performing the updates is:

php update.php --conf /srv/www-sugarlabs/pe.sugarlabs.org/wiki/LocalSettings.php
(replace pe.sugarlabs.org for the correct path for your local lab w)

If the SemanticMediaWiki extension is enabled (we don't use it), also refresh its tables:

cd extensions/SemanticMediaWiki/maintenance
php SMW_setup.php
