Upgrading to REL1_27 was a bit harder than expected.
I had to struggle with Composer and the Composer merge plugin and finally figured out how to get everything to work in concert. The trick was NOT to use the glob wildcards as suggested. Instead, your composer.local.json should look something like this:
{
"require": {
"mediawiki/lingo": "^2.0",
"mediawiki/chameleon-skin": "^1.5",
"mediawiki/semantic-media-wiki": "2.4"
},
"extra": {
}
}
Extension and Skin Upgrades[edit | edit source]
I built out on my previous shell script to get a more general purpose tool that lets me see the provenance of the code in the extensions and skins directories.
<?php
/**
* Script for discovering and upgrading all MediaWiki extensions
*
* @author Greg Rundlett greg@eQuality-Tech.com
* @copyright 2016
* @license GPLv3 or later
*
* INSTALL
* Place the script in the installation root of your MediaWiki instance i.e. "$IP"
*
* CONFIG
* The script must be configured to specify which Release you are currently running
* and the Release you want to upgrade to.
*
* You can also tell it whether you want to run composer with '--no-dev' (default)
*
* USAGE
* This script expects that you are currently using some checkout of a MediaWiki Core release
* and you want to move from that "old" release to a "new" release.
*
* Configure the $oldRelease and $newRelease variables to branch names found in
* MediaWiki core and extensions.
*
* php inspect-extensions.php
*
* SIDE-EFFECTS
* This script will run a git fetch on all your (git-controlled) extensions.
*
* LIMITATIONS
* This script will pass over any extension that doesn't have a .git folder
* It assumes that these extensions were
* * installed via Composer (without the --prefer-source option)
* * developed locally or from non-git sources
* * or downloaded as a package and we don't assume where you want to get it from
*
* This script can and will inadvertently change your checkout for extensions
* which were installed using Composer and the --prefer-source option. In those
* cases, redo a manual checkout to the branch that composer wants.
*
* This script runs on GNU/Linux. No attempt has been made to make it XP
*
