| − | | + | |
| − | '''Missing but no longer used = OK'''
| + | |
| − | * AddMediaWizard (no longer found by find/grep)
| + | |
| − | * ArrayExtension replaced by extension: Arrays (all seem to be updated)
| + | |
| − | * SyntaxHighlight (no longer used, all occurrences refer to SyntaxHighlight_GeSHi)
| + | |
| − | | + | |
| − | '''Missing, now disabled in common/local settings = OK'''
| + | |
| − | * Disabling MassEditRegex - Installed on all wikis, but not used because the currently installed version (r4) is not compatible with MediaWiki 1.18. We have tested this extension on 1.19 where it works. For some wikis this extension would be very useful.
| + | |
| − | * Disabling MathStatFunctions - probably never used.
| + | |
| − | * Disabling DynamicPageList - only installed 4 wiki, was deprecated a long time; all pages checked and function removed.
| + | |
| − | * Disabling '''FileAttach:''' Used only as testing in testwikis, now removed there.
| + | |
| − | | + | |
| − | | + | |
| − | ''' THE FOLLOWING probably may have to be disabled when migrating:'''
| + | |
| − | * MultipleUpload (also called MultiUpload) - only installed on OpenMedia, KeytoNature and OroWiki
| + | |
| − | * jQueryMsg - installed on all wikis, but obsolete in v.1.20!!
| + | |
| − | ** http://www.mediawiki.org/wiki/Git/Conversion/Extensions_still_in_svn says "jQueryMsg - Abandoned - Available in Core"

| − | '''IMPORTANT CHANGE in comparison to earlier subversion setup: we directly clone all extensions into the /extension folder, instead of cloning elsewhere and then symlinking.'''
| + | |
| − | | + | |
| − | : Memo: use "git tag -l | sort -V" um tags sortiert anzuzeigen
| + | |
| − | | + | |
| − | ===First installation only: Create git-clone on biowikifarm===
| + | |
| − | | + | |
| − | A biowikifarm git-clone (normal, not bare) of the WMF core and extension repo is created.
| + | |
| − | | + | |
| − | <syntaxhighlight lang="bash" style="font-size:105%">
| + | |
| − | # 1. FIRST create a biowikifarm git-clone (non-bare) for mediawiki-core and mw-extensions (submodules):
| + | |
| − | cd /usr/share; sudo mkdir mw-wmf-clone; cd /usr/share/mw-wmf-clone
| + | |
| − | sudo git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git core
| + | |
| − | sudo git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions.git extensions
| + | |
| − | cd /usr/share/mw-wmf-clone/extensions; sudo git submodule update --init --recursive
| + | |
| − | # Note: with after init, one can use "git foreach". Example:
| + | |
| − | # git submodule foreach 'echo $path `git rev-parse HEAD`'
| + | |
| − | # will show the path and currently checked out commit for each submodule.
| + | |
| − | </syntaxhighlight>
| + | |
| − | | + | |
| − | ===Update git and export version to folder===
| + | |
| − | | + | |
| − | Core and extensions are exported by a tar archive export out of a git clone. This works for creating the first version as well as updating. (HINT: before starting the script do a sudo command, e.g. <code>sudo ls</code> so the bash prompt knows your password and you don't have to give your password over and over again)
| + | |
| − | | + | |
| − | <syntaxhighlight lang="bash" style="font-size:105%;border-left:1px solid gray;padding-left:1em;">
| + | |
| − | # 1. Update biowikifarm clone:
| + | |
| − | cd /usr/share/mw-wmf-clone/core; sudo git fetch; cd ../extensions; sudo git pull; sudo git submodule update --init --recursive;
| + | |
| − | | + | |
| − | # 2. Now export (git archive) a specific MediaWiki versions into other folders:
| + | |
| − | wikipath="/usr/share/mediawiki20/"
| + | |
| − | | + | |
| − | if ! [ -d "${wikipath}" ]; then sudo mkdir "${wikipath}"; fi
| + | |
| − | cd /usr/share/mw-wmf-clone/core; sudo git archive 1.20.2 | sudo tar --extract --overwrite --directory="${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. Same for 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
