Mediawiki maintenance

(See also Mediawiki on biowikifarm (quick introduction/overview of setup) and the Mediawiki installation page (first time installation details).)

NOTE: the instructions below are fully valid for the 1.18/SVN setup. Some steps may differ in the current 1.20/git setup!

Mediawiki maintenance scripts

(See http://www.mediawiki.org/wiki/Manual:Maintenance_scripts)

In /usr/share/mediawiki/phase3/ copy AdminSettings.sample to AdminSettings.php, create a new user wikiadmin for mysql with localhost only, and edit AdminSettings.php accordingly. Then, for each wiki, in /var/www/wikifolder/, a symlink must be created linking to /usr/share/mediawiki/phase3/AdminSettings.php. Since we have a symlinked installation, installations scripts must run like:

 php /var/www/wikifolder/maintenance/rebuildall.php   --conf /var/www/wikifolder/LocalSettings.php
 php /var/www/wikifolder/maintenance/importImages.php --conf /var/www/wikifolder/LocalSettings.php /var/www/wikifolder/media/newimages .jpg .png .svg

Rebuild all is necessary after external text, sql, or xml imports.

Table corruption: rebuildall.php may report that a table, especially searchindex (which is MyISAM even if other tables are InnoDB) is corrupt and needs to be repaired. In phpmyadmin (http://biowikifarm.net/phpmyadmin_v3-3-7), open a sql window for the affected database, and issue: truncate table searchindex;. Running rebuildall.php afterwards concluded the repair in a case we had.

After erroneously localizing commons images not to openmedia but to local wikis, extension Nuke was used to deleted the caching-bot imports, and deleteArchivedFiles to actually delete all archived files, e.g.:

 cd /var/www/v-on/w; php ./maintenance/deleteArchivedFiles.php  --conf ./LocalSettings.php --delete

Fix problems with unparsable image names (see [1]). Needs NOT be run on regular basis, usually no problems:

 cd /var/www/v-k2n/w; php ./maintenance/cleanupImages.php --fix  --conf ./LocalSettings.php
 cd /var/www/v-on/w; php ./maintenance/cleanupImages.php --fix  --conf ./LocalSettings.php
 cd /var/www/v-species/w; php ./maintenance/cleanupImages.php --fix  --conf ./LocalSettings.php
 cd /var/www/v-species/o; php ./maintenance/cleanupImages.php --fix  --conf ./LocalSettings.php
 cd /var/www/v-species/s; php ./maintenance/cleanupImages.php --fix  --conf ./LocalSettings.php

Extension maintenance scripts

Some extensions provide their own maintenance scripts in their own extension folder. On a wiki farm, the execution of these scripts may fail due to the linked directory structure. They need an additional link (needs to be created only once):

 cd /usr/share/mediawiki/; ln -s /usr/share/mediawikistaging/phase3/maintenance
 cd /usr/share/mediawikistaging/; ln -s /usr/share/mediawikistaging/phase3/maintenance

TitleKey now installed (here only example, full set of update commands available further down!):

 cd /var/www/testwiki; php ./extensions/TitleKey/rebuildTitleKeys.php --conf ./LocalSettings.php

MediaWiki version upgrading

Core and wikimedia-base extensions

Note: To upgrade Mediawiki first run the update on the staging version (= testwiki, http://biowikifarm.net/test), then test on main version. CODE TO BE ADDED AGAIN, PRESENTLY TEST RUNS WITH THE MAIN VERSION SINCE 1.20 was first, new git checkout!

Core and extensions are exported by a tar archive export out of a git clone. This works for creating the first version as well as updating. (Suggestion: before starting the script do a sudo command, e.g. sudo ls so the bash prompt knows your password and you don't have to give your password over and over again)

 # 1. Update biowikifarm clone:
 cd /usr/share/mw-wmf-clone/core; sudo git fetch; cd ../extensions; sudo git pull; sudo git submodule update --init --recursive;

 # 2. Export (git archive) a specific MediaWiki versions into other folders:
 # First Update Core only:
 wikipath="/usr/share/mediawiki20/"
 # Create path if not yet present:
 if ! [ -d "${wikipath}" ]; then sudo mkdir "${wikipath}"; fi
 # note that git archive does not extract mw-config directory for install (?gitignored something?)
 cd /usr/share/mw-wmf-clone/core; sudo git archive 1.20.7 | sudo tar --extract --overwrite --directory="${wikipath}"
  # Note: tar provides a "--recursive-unlink" option for extract, which removes the content of the target folder
  #  However, our mediawiki installations require many additional files (svn, widget-right changes, smarty, commons-bot)
  #  which would have to be manually restored. Therefore, DO NOT use --recursive-unlink !

 # 3. Export (git archive) the extensions:
 # In list of extensions desired version is specified like the following examples:
 #  "SemanticMediaWiki"           → version HEAD + extension SemanticMediaWiki
 #  "tags/1.8, SemanticMediaWiki" → version  1.8 + extension SemanticMediaWiki
 ## NOTE: DO NOT use SemanticCalendar - this is obsolete!!!

Upgrading individual Wikimedia-based extensions

The above upgrade all extensions. If an error is detected in a single extension, it is often better to upgrade only this, since updates to other extensions may introduce new errors.

Note: in many cases it is possible to delete an extension first before updating. HOWEVER SOME EXTENSIONS need special additions or configurations beyond git and will NOT WORK if deleted and checked out. Similarly, use the dangerous "delete-all-option" "tar --recursive-unlink" only if 100% certain that this is not the case for a given extension!

Following are some examples from recent updates:

# (1) upgade all extensions managed by git
cd /usr/share/mw-wmf-clone/extensions; sudo git pull; sudo git submodule update --init --recursive;
# check for tags of a specific extension
# cd /usr/share/mw-wmf-clone/extensions/Maps; git tag -l | sort --version-sort

# (2) overwrite extension
cd /usr/share/mw-wmf-clone/extensions/MwEmbedSupport && sudo git archive --prefix=MwEmbedSupport/ HEAD | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions
cd /usr/share/mw-wmf-clone/extensions/Maps && sudo git archive --prefix=Maps/   tags/2.0.1 | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions
cd /usr/share/mw-wmf-clone/extensions/ConfirmAccount && sudo git archive --prefix=ConfirmAccount/   HEAD | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions
# OR, TO GO TO SPECIFIC RELEASE BRANCH, DO:
cd /usr/share/mw-wmf-clone/extensions/ConfirmAccount && sudo git archive --prefix=ConfirmAccount/   origin/REL1_20 | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions
cd /usr/share/mw-wmf-clone/extensions/PrefSwitch && sudo git archive --prefix=PrefSwitch/   HEAD | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions
cd /usr/share/mw-wmf-clone/extensions/Vector && sudo git archive --prefix=Vector/   HEAD | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions
cd /usr/share/mw-wmf-clone/extensions/SemanticDrilldown && sudo git archive  --prefix=SemanticDrilldown/  HEAD | \
  sudo -u www-data tar --extract --overwrite --directory=/usr/share/mediawiki20/extensions

# DELETE manually an extension directory before extracting it using bash variables
# do delete only if it is save to the extension upgrading it by deleting it first
extensionName="LiquidThreads"; versionOrTag="HEAD"; directoryFrom="/usr/share/mw-wmf-clone/extensions"; directoryTo="/usr/share/mediawiki20/extensions";
sudo ls ; # make sure sudo does not prompt for password on subsequent commands
cd "${directoryFrom}/${extensionName}" && if [ -d "${directoryTo}" ]; then rm -r "${directoryTo}/${extensionName}/"; fi && \
  sudo git archive  --prefix="${extensionName}/"  ${versionOrTag} | \
  sudo -u www-data tar --extract --overwrite --directory="${directoryTo}"

Updating extensions based in local subversion repo

 # 4. SVN-Extension UPDATING
 # If necessary: make sure www-data can update!!
 # cd /usr/share/mediawiki20/extensions && sudo chown -R  www-data:www-data ./.svn/
 # Update from LOCAL-svn with:
 cd ${wikipath}extensions; sudo -u www-data /usr/bin/svn update;

Updating additional extensions from other sources

 # 5. Additional extensions from other sources
 ### None yet.

Additional tasks

 # 6. Finishing touches. Widgets needs a writable folder:
 cd ${wikipath}
 sudo chown -R  www-data:www-data ./extensions/Widgets/compiled_templates;
 sudo chmod g+w -R  ./extensions/Widgets/compiled_templates;
 # eg. sudo chown -R  www-data:www-data /usr/share/mediawiki20/extensions/Widgets/compiled_templates; sudo chmod g+w -R  /usr/share/mediawiki20/extensions/Widgets/compiled_templates
 # Widgets does not contain all necessary code (-> Warning: require_once(/usr/share/mediawiki20/phase3/extensions/Widgets/smarty/Smarty.class.php): failed to open stream: No such file or directory...)
 # In the absence of installation instructions, using previously saved code:
 sudo cp -r /usr/share/mw-missing-code/Widgets/smarty ./extensions/Widgets
 sudo cp -r /usr/share/mw-missing-code/Widgets/googlecode ./extensions/Widgets
<!--
 # NOTE: in Dec. 2012 the parts were originally copied as seen below:
 sudo mkdir /usr/share/mw-missing-code
 sudo mkdir /usr/share/mw-missing-code/Widgets
 sudo cp -r /usr/share/mediawikistaging/ext-tagged-release/Widgets/smarty /usr/share/mw-missing-code/Widgets
 sudo cp -r /usr/share/mediawikistaging/ext-tagged-release/Widgets/googlecode /usr/share/mw-missing-code/Widgets
-->

Restart web services

sudo /usr/sbin/apache2ctl -k graceful && sudo service nginx restart && sudo service php5-fpm restart
# Optionally do other updates:
sudo apt-get update; sudo apt-get upgrade

Update, runJobs, rebuildFileCache, refreshMetadata scripts

NOTE: Add gbif-kos, check all wikis

Occasionally version upgrades of Mediawiki require an upgrade of the database structures. Again, the update.php must be called with symlink-compatible syntax. Examples for mediawiki core and titlekey extension:

Moving Cache and Media folders to different partition

Only limited space exists on the root partition itself. Larger Wiki have their Media and Cache folders relocated to the the /mnt/storage and /mnt/dump partitions, respectively. The cache of the following Wikis is presently in /mnt/dump/var/www/: testwiki-cache; v-ispi-w-cache; v-k2n-w-cache; v-lias-w-cache; v-nnvm-w-cache; v-on-w-cache; v-orowiki-w-cache; v-species-o-cache; v-species-w-cache. Move like:

# create folders on dump, then change owner and group:
cd /mnt/dump/var/www; sudo mkdir v-lias-w-cache; sudo chown www-data *; sudo chgrp www-data *;
# remove current cache, create link to new folder:
cd /var/www/v-lias/w;     sudo rm cache -r; sudo ln -s /mnt/dump/var/www/v-lias-w-cache  cache

For linking media folder (to Storage, not Dump!):

cd /mnt/storage/; sudo mkdir var-www-v-species-w-media;
sudo chown www-data var-www-v-species-w-media; sudo chgrp www-data var-www-v-species-w-media;
sudo cp /var/www/v-species/w/media /mnt/storage/var-www-v-species-w-media
## check and manually delete old media folder! Then create link:
cd /var/www/v-species/w; sudo ln -s /mnt/storage/var-www-v-species-w-media media

General topics

MediaWiki configuration tips

Configuring MediaWiki:Sidebar: New options July 2008, see [2]

It may be useful to copy the contents of http://en.wikipedia.org/wiki/MediaWiki:Common.css and http://en.wikipedia.org/wiki/MediaWiki:Monobook.css into the Mediawiki:Common.css and MediaWiki:Monobook.css pages of each Wiki where you may want to use copied things e.g. templates from wikipedia.

File uploading and Mime types

Uploading files with extensions and Content types (MIME types) usually not allowed on wikis: The default of normally allowed extensions is listed $wgFileExtensions in /includes/DefaultSettings.php (which should never be edited). To allow additional extensions override $wgFileExtensions in LocalSettings.php.

There are also $wgMimeTypeBlacklist and $wgFileBlacklist for file extensions and MIME types that are never allowed for security reasons, even if added to $wgFileExtensions. If needed for special purposes and considered safe, they can be commented out in these blacklists in LocalSettings.php.

If there is still the error message "The file is corrupt or has an incorrect extension. Please check the file and upload again", the reason can be that the file you want to upload has a MIME type for which only certain file extensions are allowed in /includes/mime.types and has an extension not listed there. If considered safe, the extension can be added in that file. The mime type can be determined with the command file -i filename. Note: Files that are changed manually are then excluded from svn update. To drop own changes and get back to the svn version delete the file and then run svn update (see above).

Logging/Debugging

For debugging, you may enable logging of debug and error messages:

# create a log-file somewhere
  sudo touch /var/www/v-k2n/w/log.txt
  sudo chmod 777 /var/www/v-k2n/w/log.txt

# edit LocalSettings.php and add the following line after the line including the DefaultSettings.php:
  $wgDebugLogFile = "/var/www/v-k2n/w/log.txt";

Note, that the logfile will grow fast, so one should switch on the logging only for short periods of time, and delete the logfile after done.

PHP debugging can be doen with xdebug. Details see Mediawiki debugging.

Backup/Restore in general

Backing up the database alone is documented here: http://www.mediawiki.org/wiki/Manual:Backing_up_a_wiki. A more complete script can be found here: http://www.mediawiki.org/wiki/User:Flominator/Backup_MW - this also backups the folder with uploads (media). Based on that source, adapted scripts were created, execute as:

 cd /var/backups/scripts/; ./backup-mw.sh

The additional backup-mw.php script can potentially be used within www to directly create and download a copy of the mediawiki. We are considering this as a measure to build trust.

In addition, to create an xml dump, make sure a link to AdminSettings.php exists in the current wiki folder and the maintenance folder is temporarily copied, then run, e.g.:

 cd /var/www/v-on/w;   sudo -u www-data php ./maintenance/dumpBackup.php  --full --conf ./LocalSettings.php > /var/www/v-orowiki/w/media/full.xml

To restore such a xml-dump, remove tables and create new tables with default values in mysql, then:

 cd /var/www/WIKINAME;  # (replace path with actual wiki path!)
 php ./maintenance/importDump.php /var/backups/wikis/k2n-full.xml --conf ./LocalSettings.php
 php ./maintenance/rebuildrecentchanges.php --conf ./LocalSettings.php    # absolutely necessary
 ## If backlinks etc. do not work, or extensions had to be disabled, use (Very slow!!!!):
 php ./maintenance/rebuildall.php  --quick --conf ./LocalSettings.php

Notes: In our experience, some extensions may create problems during reimport. We found GoogleMaps and DynamicPageList to cause importDump to abort. After disabling these two extensions, the import worked correctly. However, all DPL pages are then still cached without proper DPL rendering even after re-enabling both extensions. Running rebuildall.php fixed this.

Example restore for testing of the wikimediafoundation commons xml-dump:

 cd /var/www/wmf-commons; php ./maintenance/importDump.php  /mnt/wpTest/commonswiki-pages-articles.xml  --conf ./LocalSettings.php

Refresh SemanticMW data

If it becomes necessary to delete all SMW data in a particular wiki and regenerate the data again from the individual pages the following command lines can be used:

 cd /var/www/WIKINAME;  # (replace path with actual wiki path!)
 sudo -u www-data php ./maintenance/runJobs.php -v --procs 4 --conf ./LocalSettings.php
 sudo -u www-data php ./extensions/SemanticMediaWiki/maintenance/SMW_refreshData.php -ftpv --conf ./LocalSettings.php
 sudo -u www-data php ./extensions/SemanticMediaWiki/maintenance/SMW_refreshData.php -v --conf ./LocalSettings.php
 sudo -u www-data php ./maintenance/runJobs.php -v --procs 4 --conf ./LocalSettings.php

Notes:

change to the local directory of the wiki to be refreshed,
make sure all outstanding jobs are completed,
delete all SMW data,
regenerate the data from the individual pages.

The last step can take some time (e.g. about 10 minutes to refresh about 4000 IDs). The wiki seems to work normally during that time but queries may be effected. For that reason it is recommended to implement this operation during a maintenance window.

During step 4 the procedure slows down after about 5 min. and can be sped up by:

interrupting the procedure by using Crtl-C
restarting the last command by specifying the next ID to be processed, e.g.

php ./extensions/SemanticMediaWiki/maintenance/SMW_refreshData.php -v -s 2062 --conf ./LocalSettings.php

if 2061 IDs had been already processed at the time of the interruption.
