"Sedan MediaWiki 1.19beta2, 1.18.2, 1.17.3, använder MediaWiki bas och tillägg Git för versionshantering. För äldre versioner, se Subversion"

Git är ett distribuerat versionshanteringssystem som möjliggör att användare laddar ned den absolut senaste versionen av en gren, utan att behöva vänta på att någon paketerar den. MediaWiki kan snabbare göra leveransversioner, och det kommer vara lättare för dig att uppdatera din installation, rulla tillbaka en uppgradering, eller skicka programfixar. (Kom dock ihåg att officiella stabila leveransversioner är mindre riskfyllda.)

Se Git för fler detaljer, speciellt när det handlar om att göra bidrag. Nedan är några kortfattade instruktioner för ofta förekommande uppgifter.

Förutsättningar

Du måste ha Git installerat innan du kan använda det. Det finns många olika sätta att installera Git, beroende på operativsystem. För källkod och officiella binärer, leta på git-scm.com. För alternativa sätta att installera Git, använd en sökmotor för att hitta instruktioner för ditt operativsystem.

Det rekommenderas att du har Composer installerat för att ladda ner och installera tredjepartsbibliotek, men det är inget krav.

Använda Git för att ladda ner MediaWiki

Ladda ned

Du kan ladda ner MediaWiki bas med Git, och även alla tillägg för närvarande installerade i Wikimediastiftelsens serverkluster och många andra tillägg tillgängliga på gerrit .

Det första steget är att klona MediaWiki core-arkivet. Detta kan ta ett tag.

In a terminal window, enter the following command:

git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git --branch REL1_31 mediawiki

This clones the entire MediaWiki core repository, initially pointed at release branch 1.31, into a sub-directory named mediawiki.

To install into different directory, change that in the command line (for more info refer to these docs). Once the repository is cloned, you can easily switch to different branches or tags (see below), including those tracking unstable versions of MediaWiki. The development branch, master, is the cutting-edge, developer version of MediaWiki; you should not use master code for production under any circumstances as it is not considered stable.

If you want to reduce the number of revisions that are cloned, add --depth=1 to the above command.

The release branches have a bunch of Git submodules in them, for commonly-used extensions and skins (the master branch does not have these). To update the submodules, run:

cd mediawiki
git submodule update --init

Download for development

If you have a developer account (which is easy to request), then instead of cloning anonymously with https you should clone with your ssh <USERNAME> so that you can submit changes for review:

git clone ssh://<USERNAME>@gerrit.wikimedia.org:29418/mediawiki/core.git mediawiki

This clones the entire MediaWiki core repository, synced to the master branch, into a sub-directory named mediawiki.

Fetch external libraries

MediaWiki uses Composer to manage external PHP libraries, all of which end up in the vendor/ directory in your MediaWiki directory.

To install these needed libraries, you have a choice:

  • Download and install the composer PHAR, optionally rename the composer.phar file as instructed for your OS, and then run composer update --no-dev from your MediaWiki directory. This is the recommended approach.
  • Or, if you don't want to use Composer or if you want to use the exact same set of vendor libraries as used on the WMF production cluster, you can instead git clone https://gerrit.wikimedia.org/r/p/mediawiki/vendor.git to create a vendor/ directory inside the core folder of your MediaWiki installation. Note that if any of your extensions have their own Composer requirements, then you can not use this option.

Prior to MediaWiki 1.25, external libraries were kept in the core repository, and no package manager was required.

MediaWiki tags (stable version)

Alternatively, specific stable versions of MediaWiki are tracked using 'tags'. These are analogous to the tarball releases. Currently, these are 1.31.1 (stable), 1.27.5 (LTS) and 1.30.1 (legacy).

You can see all available tags with:

git tag -l | sort -V

Using non GNU sort command, such as on Mac OS X, you have to rely on the good old separators:

git tag -l | sort -n -t. -k1 -k2 -k3

To use a specific tag, e.g. the latest stable release:

git checkout 1.31.1

Latest development version of MediaWiki

The latest development version of MediaWiki is tracked in the 'master' branch. This is what is locally checked out by default when you first clone the MediaWiki repository. If you have switched to another branch but would like to switch back to using bleeding-edge MediaWiki, do:

git checkout master

Håll dig uppdaterad

If you're using a particular branch or the development version ("master" branch) of MediaWiki, picking up the latest changes is relatively easy. Change into your MediaWiki clone directory and issue this command:

git pull

All of the latest changes for the branch you are using will be applied.

The new version of core may require newer versions of extensions and skins, so you must go into each extension and skin directory and update it with a command like git pull --recurse-submodules.

You also need to update vendor/ with any newer versions of required libraries. This often means running the following Composer command, but see #Fetch external libraries above for more details:

composer update --no-dev

After updating/upgrading the code and required libraries you should run the MediaWiki update.php command-line script to update database tables as needed:

php maintenance/update.php

If you use MediaWiki-Vagrant, it offers a single command, vagrant git-update, that performs all these steps.

Switching to a different version

Switching to a different version of MediaWiki is far simpler with Git than with SVN. Each of our versions are tracked as branches or tags. In order to switch to one of these, all you have to do is checkout the particular branch or tag you want from within your MediaWiki clone directory:

git checkout <branchname>

or

git checkout <tag name>

The changes will be applied automatically and you will be all set to go.

Using Git to download MediaWiki extensions

List of extensions in git

Ladda ned en förlängning

<EXT> should be replaced with the name of the extension you want to download, without spaces. For Extension:TitleKey, it would be TitleKey. (case sensitive!)

Download and clone an extension from Git:

cd /path/to/extensions
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/<EXT> --branch REL1_31

Developers clone with:

git clone ssh://<USERNAME>@gerrit.wikimedia.org:29418/mediawiki/extensions/<EXT> --branch REL1_31

You can view extension source code in Gerrit's gitiles application, and at the URL:

https://gerrit.wikimedia.org/g/mediawiki/extensions/<EXT>/+/refs/heads/master

Download all extensions

If you prefer to have all MediaWiki extensions that are at gerrit.wikimedia.org checked out to your machine, enter the following:

git clone https://gerrit.wikimedia.org/r/mediawiki/extensions --branch REL1_31
cd extensions
git submodule update --init --recursive

Thereafter, to update all extensions to their latest versions of that branch, just enter:

cd /path/to/extensions
git pull
git submodule update --init --recursive

To change to a different branch, such as after a new release:

git submodule foreach 'git checkout -b REL1_30 origin/REL1_30 || :'

Remember that you should only use versions of extensions from the same release as that version of MediaWiki and each other.

To track the master branch:

git submodule foreach 'git checkout -b origin/master || :'

Please note that you should not use master code for production under any circumstances as it is not considered stable.

If you only need a read-only checkout (for instance to grep or analyse all MediaWiki code), you can use the shared MediaWiki checkout on Labs, without downloading anything on your machines.

Ta bort en förlängning

Ta bort tilläggskatalogen och ta bort "require_once …" eller "wfLoadExtension( … )" från LocalSettings.php.

Använd Git för att ladda ned MediaWiki-utseenden

Lista av utseenden i git

MediaWiki 1.24 och senare inkluderar inte utseenden i Git-nedladdningen.

Följ exakt samma process som för förlängningar (beskrivet i en tidigare sektion), men använd skins istället för extensions i alla URLer och sökvägar.

Detaljerade installationsinstruktioner finns på varje utseendes sida här på MediaWiki.org, till exempel Skin:Vector#Installation. Instruktioner för alla andra utseenden är liktydiga.
