Composer managed libraries required or recommended for use with MediaWiki. This repository is maintained for use on the Wikimedia Foundation production and testing clusters, but may be useful for anyone wishing to avoid directly managing MediaWiki dependencies with Composer.
Checkout this library into $IP/vendor using git clone <URL> or add the
repository as a git submodule using git submodule add <URL> vendor followed
by git submodule update --init.
- Read the documentation on the process for adding new libraries.
- Ensure you're using the latest version of 2.2.x of composer via
composer --version. This keeps installed.json alpha-sorted, making patches less likely to conflict, and diffs easier to read. - Edit the composer.json file to add/update the libraries you want to change.
It is recommended that you use
composer require <package> <version> --no-updateto do so as composer will then automatically sort the composer.json file. - Run
composer update --no-devto download files and update the autoloader. - Add all the new dependencies that got installed to composer.json as well, so that everything has their version pinned. (You can look at the changes in composer.lock or composer/installed.json to see what they are.)
- In some cases, the libraries might include not needed files (e.g. test files,
project files, etc). If you cannot exclude them from library's archive
(e.g. by
export-ignoreing unwanted files in library's.gitattributesfile), you can skip checking them in by listing them in.gitignorefile. - Rarely, lint checks fail because test files in some library were written for an unsupported PHP version. In that case add the test directories to the --exclude parameter in the script > test field in composer.json, and to .gitignore.
- Add and commit changes as a gerrit patch.
- Review and merge changes.
Note that you MUST pair patches changing versions of libraries used by MediaWiki
itself with ones for the "core" repo. Specifically, the patch in mediawiki/core
must have a Depends-On footer to the patch in mediawiki/vendor.
The vendor repo has special configuration, which skips the integrity checks and so allowing a circular dependency Gordian knot to be fixed. However, this means that, if merged alone without a pair, you'll cause ALL patches in MediaWiki and ALL extensions to fail their continuous integration tests.
If in doubt, seek advice from regular commiters to this repository.
