Wiki instances

The main wiki lives here at /srv/www-sugarlabs/wiki/

Except for trivial changes, work on the wiki should be carried in the parallel wiki-devel instance before landing onto the production instance.

Note: The devel wiki has an out of date snapshot of the DB and a slightly different LocalConfig.php.

{{Highlight|Note: Often, the devel instance contains changes performed by various wiki admins to test extensions and configuration options. Do not sync LocalConfig.php blindly to the production wiki! Use vimdiff.

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).

Installation

Our MediaWiki instances are installed from git to allow easy rebasing of our changes on upgrades. For the full details on this installation method, see http://www.mediawiki.org/wiki/Download_from_Git

The initial setup process (probably outdated now) lookd like this: 

git clone https://gerrit.wikimedia.org/r/mediawiki/core.git --branch REL1_34 wiki-devel
cd wiki-devel
git submodule update --init

Checkout additional extensions we wish to enable. For ease of management, check them out into extensions-all and then symlink them from extensions/ 

EXTENSIONS=CheckUser ContributionScores HTMLets LastUserLogin LdapAuthentication MobileFrontend TimedMediaHandler UniversalLanguageSelector UserMerge VisualEditor Widgets

mkdir extensions-all
for i in EXTENSIONS; do
  git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/$i extensions-all/$i --branch REL1_34;
  (cd extensions && ln -s ../extensions-all/$i);
done

Upgrading

Note: Before blindly following the procedure below, check the official documentation for anything that might have changed: 

https://www.mediawiki.org/wiki/Download_from_Git#Keeping_up_to_date

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

git fetch
git branch -a | grep REL | sort -V
git checkout -b REL1_XX origin/REL1_XX
git submodule update --init

The "extensions-all" directory contains a bunch of git repositories stitched together with 'git submodule'. To update it: 

cd extensions-all
for ext in *; do (cd $ext && git fetch && git checkout -b REL1_XX origin/REL1_XX); done

You also need to update some dependencies using a PHP manager called 'composer': 

composer update --no-dev

Now run update script: 

php maintenance/update.php

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

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

Obsolete documentation

SemanticMediaWiki

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

cd extensions/SemanticMediaWiki/maintenance
php SMW_setup.php

Skins

As of this writing, the default skin vector is integrated into MediaWiki, and we don't load other skins in LocalSettings.php.

The skins also need to be updated from time to time (particularly after a major release). Instead of checking out hundreds od skins using the official process, we refresh only the skins that are installed: 

cd skins
for i in MonoBook Timeless; do
  (cd $i && git fetch && git checkout -b REL1_34 origin/REL1_34)
done


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
