MediaWiki version 1.23.8 is a long term support version.

Architecture

See also http://biowikifarm.net/meta/Mediawiki_installation#Cloning_a_new_wiki Approach:

  • have a Long Term Support (LTS) Version of a MediaWiki Git clone
  • install extensions for a wiki version
  • install WEB_WIKI by web interface or Database template

Schema: 

 MW_WMF_CLONE                                        /usr/share/mw-wmf-clone
 ├ core (Git) ─────────git-archive-export───┐        /usr/share/mw-wmf-clone/core
 └ extensions (Git) ───git-archive-export─→ ) ─┐     /usr/share/mw-wmf-clone/extensions
                                            │  │
   WIKI_SOURCE_LTS (e.g. REL1_23)           │  │
   ┌ core-files (local git archive-export) ←┘  │     /usr/share/mediawiki23
   ├ extensions (mixed:                        │     /usr/share/mediawiki23/extensions
   │   svn biowikifarm, (repo: as svn-post-commit)
   │   git-archive-export)  ←──────────────────┘
   │   some svn extensions from MediaWiki            Extension:StringFunctions
   ↓   
   │ WEB_WIKI (as LTS web Wiki)
   ├─→ core-files (linked)                           /var/www/v-infoflora/d/
   └─→ extensions (linked)                           /var/www/v-infoflora/d/extensions
         composer-extensions must be dealt with      /var/www/v-infoflora/d/composer.json
         on level WEB_WIKI individually

Script(ed) installation

Try to install it from scratch and using no template (for the first time)

“Global Variables”

##↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
# set global variables
do_not_install_but_show_dry_run="" # "" or "anything-but-non-empty"
if [ "$do_not_install_but_show_dry_run" != "" ]; then 
  install_notice="DRY RUN (nothing is done)";
else
  install_notice="INSTALL";
fi

git_mw_basedir="/usr/share/mw-wmf-clone"
git_mw_core_source_dir="${git_mw_basedir}/core"
git_mw_extension_source_dir="${git_mw_basedir}/extensions"
git_branch="origin/REL1_23"
git_tag="1.23.8"

v_wiki_folder="./v-infoflora"
v_wiki_sub_folder="" # default ""
web_wiki_script_folder="./d" # default ./w for wiki or web or what ever
web_wiki_config_folder="./mw-config" # default ./mw-config
web_base_dir="/var/www"

if [ "${v_wiki_sub_folder}" == "" ];then
  web_wiki_base_dir="${web_base_dir}/${v_wiki_folder}/${web_wiki_script_folder}"

mw_LTS_version_source_extension_path="${mw_LTS_version_source_path}/extensions"
# echo "$mw_LTS_version_source_extension_path"

if [ "`command -v realpath`" ]; then web_wiki_base_dir=`realpath "$web_wiki_base_dir"`; fi

# end of global variables

MW_WMF_CLONE Upgrade

Possible approaches after upgrading the MW_WMF_CLONE

  • checkout a LTS-branch and copy these sources to WIKI_SOURCE_LTS
  • export by git archive <tag-or-branch-or-tree-ish> to WIKI_SOURCE_LTS

Upgrade wmf-git-clone 

##↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
cd "${git_mw_core_source_dir}"; 
  sudo git pull;
  git branch -r | sort --version-sort # list branches
  git tag -l | sort --version-sort # list tags
cd "${git_mw_extension_source_dir}";
  sudo git pull; sudo git submodule update --init --recursive;
  git branch -r | sort --version-sort # list branches
  git tag -l | sort --version-sort # list tags
##↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑

Checkout a branch

  • may be skipped, because later a branched or tagged archive will be exported and no copy-and-paste of a checkout
##↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
# STEP checkout git clone to git_branch for the subsequent export?
#
cd "${git_mw_core_source_dir}"
  # git branch -r | sort --version-sort # list branches
  # git tag -l | sort --version-sort # list tags
  if [ "$do_not_install_but_show_dry_run" == "" ]; then
    sudo -u root -g mwadmin git checkout -b $git_branch $git_tag
  fi
  printf "\e[47mgit clone in '\e[42m%s\e[47m' is checkout to branch: '%s' tag: '%s'\e[0m\n"  "${git_mw_core_source_dir}" "$git_branch" "$git_tag"
cd "${git_mw_extension_source_dir}" 
  # git branch -r | sort --version-sort # list branches
  # git tag -l | sort --version-sort # list tags
  # extensions seem to have no tags
  if [ "$do_not_install_but_show_dry_run" == "" ]; then
    sudo -u root -g mwadmin git checkout -b $git_branch
  fi
  printf "\e[47mgit clone in '\e[42m%s\e[47m' is checkout to branch: '%s' (extensions seem to have no global tags)\e[0m\n" "${git_mw_extension_source_dir}" "$git_branch"
# end checkout of git clone in git_mw_basedir
##↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑

MW_WMF_CLONE → WIKI_SOURCE_LTS

  • Create a MediaWiki versioned source (the source of a LTS-version)
  • Create extension sources, extract Git extensions to WIKI_SOURCE_LTS
    • biowikifarm extensions
    • no further developed extension still necessary fro biowikifarm
    • Git extensions from MW_WMF_CLONE

Extract the right branch or tag of an extension from MW_WMF_CLONE for this WIKI_SOURCE_LTS. Note, the list of EXTENSIONS may not be complete but it seems unnecessary to extract all 663 extensions shipped with the wmf git clone.

Install composer extensions

These extensions must be dealt with at level WEB_WIKI. Documentation

Extensions you want to remove you must do it with composer 

##↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
# get, install PHP composer tool
cd ~ # go to personal home directory

(Re)Move old Git extensions

The problem is, that extensions managed by git must be removed in favour of composer management. Composer installs also dependencies so take care also of dependent extensions documented by extension developers, e.g. SemanticMaps in composer will also install extension Maps. The following script just renames old extension folders to make room for the composer managed extensions. In case of SemanticMaps it’s only necessary to do … 

sudo php /usr/local/bin/composer.phar require mediawiki/semantic-maps '3.1.3'

… but you must take care of the extension folder Maps (if present) manually.

Settings for LocalSettings.php

Set correct rights 

sudo chmod 664 "${web_wiki_base_dir}/LocalSettings.php" # rw-rw-r--
sudo chown root:mwadmin "${web_wiki_base_dir}/LocalSettings.php"

There are alternative approaches:

  1. use web installer of the new Wiki
  2. use command line installer in maintenance/install.php
    •  ?does it try to override a LocalSettings.php?
    • it seems to need an Admin User to be defined (problem with shared user tables?)
    • see Manual:Shared database → Upgrading. ?make use of command line option --doshared?
  3. copy old database template (database z_en_template in https://biowikifarm.net/phpmyadmin_v3-3-7/) and adjust it as well as settings for LocalSettings.php
    • see in MediaWikiCommonSettings.php (some settings there might interfere with MW 1.23 due to software changes)
    • see other files of LocalSettings.php

To get it work with composer add the following somewhere in LocalSettings.php: 

if (is_readable("$IP/vendor/autoload.php")) require( "$IP/vendor/autoload.php");

Nginx Configuration

See also Nginx Installation and Configuration. Tips:

General architecture 

/etc/nginx/nginx.conf - basic settings
└→ include /etc/nginx/sites-enabled/* - actual sites configured ready for production
   * default file - for common settings of that server the no-URL-resolving redirects back to
┌→ * configuration files for each server
│ (linked)
/etc/nginx/sites-available/* - potentially available sites files for each server

Installation Issues, Problems, Transition form Older Wikis

  • RELEASE-NOTES: read/check file mw-source/RELEASE-NOTES-X.XX, changes are described there, class changes, core changes and deprecated functions
  • composer management: problem is that composer extensions are handled on the level WEB_WIKI by composer not by require_once("…")
  • Extension:Cite becomes extension CiteThisPage (MW 1.24+)
  • Extension:ContacPage has special installation (MW1.23+) https://www.mediawiki.org/wiki/Extension:ContactPage#Installation
  • Extension:ExpandTemplates is now in MW1.23+ core, separate installation is no longer necessary (require_once("…"))
  • Extension:GlobalUsage has no more class names with underscore. Adjust configuration of $wgLBFactoryConf in LocalSettings.php see also http://noc.wikimedia.org/conf/highlight.php?file=db.php
  • Extension:Vector is in core MW 1.22+, separate installation is no longer necessary (require_once("…"))

Dependencies:

  • Extension:TimedMediaHandler dependent on Extension:MwEmbedSupport
  • biowikifarm Extension:MobileKeyV1, Extension:MobileKeyV2 are dependent on Extension:TemplateParameterIndex
  • Extension:BetaFeatures is a light dependency of Extension:MultimediaViewer

Composer extensions see above

No further development

Installation Problems

  • A user_password_expires column has been added to the user table
/usr/share/mediawiki23/maintenance/archives/patch-user_password_expire.sql
# MYSQL-patch see release notes: ALTER TABLE user ADD COLUMN user_password_expires varbinary(14) DEFAULT NULL; -- done so far for biowikifarm
  • location in nginx path must match $wgScriptPath $wgArticlePath
  • load.php gave internal server error 500
    debug on: nothing conclusive
    nginx logs: PHP message: PHP Fatal error: Cannot override final method SMW\ResultPrinter::getResult() in /var/www/v-infoflora/d/extensions/SemanticResultFormats/formats/Exhibit/SRF_Exhibit.php on line 468
    $srfgFormats[] = 'exhibit'. in SemanticResultFormats v2.0 causes fatal error, see https://phabricator.wikimedia.org/T59760
  • Google Maps API Key neccessary?
  • <gallery> needs a new setting in $wgGalleryOptions for 'mode' otherwise MWException
    'mode' => 'traditional', // One of "traditional", "nolines", "packed", "packed-hover", "packed-overlay"

Installation Issues: Semantic MediaWiki

  • Extension:SemanticForms 3.0+ (edit with form) the implementation of forms has changed to {{#default_form:form}}
  • #set_internal saves differently on a property page "Property:property-name" not just "property-name", has consequences for querying. You could use a count check for the query to see if a property prefix is neccessary:
{{#ifexr: {{#ask: [[internal object::{{{property|}}}]]|format=count}}|<!-- no prefix: older SMW -->PAGENAME|<!-- prefix property -->FULLPAGENAME}}
