This is a planning document

How-to is here: https://www.mediawiki.org/wiki/Download_from_Git . Checking extensions: Which extensions previously obtained from WMF-Subversion (i.e. excluding those we have in local SVN) are Not in the following list of git-migrated mediawiki extensions? https://gerrit.wikimedia.org/r/#/admin/projects/

Useful resources for understanding git checkout, head, detached head, --track:


Comparing 1.20 git-extensions with 1.18 and above, Nov. 2012

Local SVN are now in same folder as git checkout = OK

Manually copied i.e. now available in the 1.20git extension folder:

  • SMWAskAPI - only installed on offene-naturfuehrer = OK

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:


New mediawiki git notes - LATER MOVE TO MW Maintenance!

Main source: mediawiki.org: Download from Git. See also overview of wikimedia projects in Git.

IMPORTANT CHANGE in comparison to earlier subversion setup: we directly clone all extensions into the /extension folder, instead of cloning elsewhere and then symlinking.

Background: git creates a full copy of the repository. Since we need several parallel branches, we clone once into mediawiki-git, and from there locally into further repose. Local repos use hardlinks, so they do not need much additional hard drive space (Note: git uses hardlinks inside .git, see ls -l: hardlink number is col. before owner; the checkout is NOT hardlinked and requires additional space.).

# 1. FIRST create a local git-clone for mediawiki-core (bare) and mw-extensions (submodules, cannot be bare):
cd /usr/share; sudo mkdir mediawiki-git; cd /usr/share/mediawiki-git
sudo git clone --bare 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/mediawiki-git/extensions; sudo git submodule update --init --recursive
# Note: with the submodule, after init, one can use foreach.
#   Example of foreach: git submodule foreach 'echo $path `git rev-parse HEAD`' 
#   will show the path and currently checked out commit for each submodule.


# INSERT: NEW ALTERNATIVE TEST WITH MIRROR INSTEAD. BUT THE PROBLEM IS WITH THE SUBMODULES recloning, NOT WITH CORE.
# 1.XXX FIRST create a local git-clone for mediawiki-core (bare) and mw-extensions (submodules, cannot be bare):
# using mirror option, because we want to subclone from this clone again.
cd /usr/share; sudo mkdir mw-wmf-mirror; cd /usr/share/mw-wmf-mirror
sudo git clone --mirror https://gerrit.wikimedia.org/r/p/mediawiki/core.git core
# Now create mirror-clones of each extension based on the submodule. Note: Simply using:
#  git clone --mirror https://gerrit.wikimedia.org/r/p/mediawiki/extensions.git extensions; 
#  git submodule update --init --recursive 
#  will not work in second step, when this clone is locally re-cloned (for different version checkouts)
cd /usr/share/mw-wmf-mirror; sudo mkdir extensions; cd /usr/share/mw-wmf-mirror/extensions;

# 3. Also insert the local-svn-managed extensions into the same folder:

# Note: a list of UNUSED extensions is available on earlier versions of this page

Updating mediawiki (git+svn)

 # 1. Update LOCAL-git core and extensions from WMF-git:
 cd /usr/share/mediawiki-git/core; sudo git fetch; cd ../extensions; sudo git pull; sudo git submodule update --init --recursive;
 # 2. Reset local mediawiki installations prior to the update:
 # (Note: HEAD is head of current branch i.e. head after checkout REL1_20 is 1.20, not master.
 # (Use "git branch" or "git branch -a" to check which branch is active.)
 cd /usr/share/mediawikiPP; sudo git checkout origin/master; cd extensions; (for f in *; do cd "$f" && sudo git checkout origin/master && cd ..; done);
 cd /usr/share/mediawiki20; sudo git checkout origin/master; cd extensions; (for f in *; do cd "$f" && sudo git checkout origin/master && cd ..; done);
 # 3. Update local mediawiki20, mediawikiPP from LOCAL-git and LOCAL-svn with:
 cd /usr/share/mediawiki20; sudo git pull; cd extensions; (for f in *; do cd "$f" && sudo git pull origin/master && cd ..; done); /usr/bin/svn update;
 cd /usr/share/mediawikiPP; sudo git pull; cd extensions; (for f in *; do cd "$f" && sudo git pull origin/master && cd ..; done); /usr/bin/svn update;
 ## Note: LATER check whether the git pull commands above are really necessary. It always reports "already up-to-date" - perhaps due to the hardlinks?

 # 4. switch to the desired version again (AFTER UPDATING), see next section...

Updating mediawiki to specific versions

SWITCH INSTALLATIONS TO SPECIFIC TAGS:

 # Note: to see all branches/tags do: 
 git branch -r | sort --version-sort
 git tag -l | sort --version-sort


 # Mediawiki core:
 cd /usr/share/mediawikiPP; sudo git checkout origin/REL1_19
 cd /usr/share/mediawiki20; sudo git checkout origin/REL1_20
 # SMW extensions:
 # find tags online: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/SemanticMediaWiki.git;a=tags
 # on the commend line: git tag -l | sort --version-sort

After this:

cd /var/www/testwiki_v20; sudo -u www-data php ./maintenance/update.php  --quick --conf ./LocalSettings.php

  • Changed field type, see [1]* ./maintenance/update.php running through.
