How to become a MediaWiki hacker/pl

Ten artykuł został napisany, aby pomóc programistom nauczyć się podstawowych umiejętności potrzebnych do współtworzenia MediaWiki core i rozszerzeń MediaWiki'''. Zwróć uwagę, że w większości przypadków podczas pracy z MediaWiki nie chcesz dłubać w rdzeniu MediaWiki, chyba że naprawdę wiesz, co robisz.

Główną ścieżką do rozpoczęcia rozwoju Wikimedia jest przyczynianie się do projektów Wikimedia, które oferują mentoring. Alternatywą bez mentoringu jest naprawienie pierwszego błędu.

Jeśli jesteś doświadczonym programistą, który jest już zaznajomiony z używaniem MediaWiki, zamiast tego odwiedź .

Przegląd
MediaWiki to oprogramowanie, które obsługuje Wikipedię, jej siostrzane projekty i tysiące wiki na całym świecie.

MediaWiki jest napisane w języku programowania PHP. Używa jako biblioteki JavaScript klienta.

MediaWiki jest głównie napisane dla platformy LAMP i działa na większości systemów operacyjnych. MediaWiki wykorzystuje przede wszystkim serwery baz danych MySQL i MariaDB.

Oprogramowanie MediaWiki jest rozwijane na licencji open source. Rozwój koordynowany jest online i wspierany przez Wikimedia Foundation, ale dużą rolę pełnią też wolontariusze.

This page should help you become a contributor to MediaWiki. It is not a tutorial; it just points you to various places where you can go learn whatever is necessary.

Set up your development environment
Most projects use Git and Gerrit. Follow the Gerrit tutorial to set up your developer account. Then you can move on to downloading our code, making changes, testing them, and submitting patches. There are two ways to set up your development environment: using a pre-configured virtual machine setup (Docker or Vagrant), or a manual configuration approach.

Docker development environment
This is the recommended method.
 * MediaWiki Docker – Run MediaWiki using Docker (can be used on Linux, Windows, or macOS hosts).

You can also try the experimental mwcli tool which provides basic orchestration functionality for MediaWiki docker containers.

Virtual Machine with Vagrant

 * Vagrant installation — These steps will install MediaWiki server with all the requirements inside a Linux virtual machine (can be used on Linux, Windows, or Mac hosts).

Vagrant is a powerful tool, but it is more complex and less robust than Docker, and significantly more resource-intensive. It is mainly aimed at developers who need to set up complex, flexible environments, e.g. for testing the interaction of multiple extensions.

Manual installation

 * Installation requirements — Check hardware requirements, and install a LAMP, MAMP or WAMP server (Linux, Mac or Windows, plus Apache, MySQL/MariaDB and PHP).
 * — Download the latest source code from Git.
 * — Continue with the installation and initial configuration.
 * Set up the various debug modes in your environment to display warning and errors early.

It's not necessary to download Wikipedia database dumps in order to develop MediaWiki features. In fact, in many cases it's easier to use a near-empty database with a few specially-crafted test pages. However, if for some reason you want to have a copy of Wikipedia, you can get a dump.

PHP
MediaWiki is written in PHP, so you'll need to get familiar with PHP to hack MediaWiki's core.


 * Learn PHP
 * PHP tutorial — Available in many different languages. If you have no knowledge of PHP but know how to program in other object-oriented programming languages, PHP will be easy for you to learn.
 * PHP Programming at Wikibooks.
 * PHP topic at Wikiversity.


 * PHP resources :
 * The PHP manual — Available in many different languages.
 * PHP coding conventions within the MediaWiki community.


 * Stuff to know :
 * The script  in MediaWiki provides a basic PHP interpreter with MediaWiki objects and classes loaded.
 * Also, the script  in MediaWiki is a replacement of   based on PsySH, see Manual:Shell.php

Database
Many features require some amount of database manipulation, so you'll often need to be familiar with MySQL/MariaDB.


 * Learn MySQL/MariaDB
 * MySQL tutorial — From the MySQL 5.0 reference manual.
 * MySQL at Wikibooks.


 * MySQL/MariaDB resources
 * MySQL Reference Manuals — Available in many different languages.
 * MariaDB Knowledge Base
 * Database coding conventions within the MediaWiki community.


 * Stuff to know :
 * Test your code with MySQL/MariaDB.
 * MediaWiki currently uses MySQL and MariaDB as the primary database back-end. It also supports other DBMSes, such as PostgreSQL and SQLite. However, almost all developers use MySQL/MariaDB and don't test other DBs, which consequently break on a regular basis. You're therefore advised to use MySQL/MariaDB when testing patches, unless you're specifically trying to improve support for another DB. In the latter case, make sure you're careful not to break MySQL/MariaDB (or write queries that are horribly inefficient in it), since MySQL/MariaDB is what everybody else uses.

JavaScript and CSS
JavaScript and CSS have become omnipresent in front-end code. You don't have to be familiar with JavaScript, jQuery and CSS to work on MediaWiki, but you might need to, depending on what you choose to work on.


 * Learn JavaScript and CSS
 * JavaScript and CSS at Wikibooks.
 * Getting Started with jQuery — A jQuery tutorial.
 * Learning JavaScript — references and sources.


 * JavaScript and CSS resources
 * JavaScript coding conventions within the MediaWiki community.
 * CSS coding conventions within the MediaWiki community.

MediaWiki
The MediaWiki code base is large and some parts are ugly; don't be overwhelmed by it. When you're first starting off, aim to write features or fix bugs which only touch a small region of code.


 * MediaWiki basics and must-reads :
 *  — A high-level overview of the main components of MediaWiki and how they work with each other.
 *  — An overview of why and how to write secure code.


 * MediaWiki resources :
 * — A list of important files and links to more detailed information.
 * — A list of hooks. If you're trying to find what part of the codebase does something, often a good place to start is by searching for the related hooks.
 * — An overview of general coding conventions within the MediaWiki community.


 * Code documentation ( class reference ) — Automatically generated documentation from the code and code comments.
 * — A guide to debugging MediaWiki.
 * — A tool to interact with MediaWiki objects live.
