How to become a MediaWiki hacker/tr

Bu madde, geliştiricilere MediaWiki geliştirmeye katkıda bulunmak için gereken temel becerileri öğrenmelerinde yardımcı olmak için yazılmıştır.

MediaWiki'yi zaten tanıdık deneyimli bir geliştiriciyseniz, onun yerine  sayfasını ziyaret edin.

Genel bakış
MediaWiki, Wikipedia'nın, onun kardeş projelerinin ve binlerce wikinin tüm dünyada güç sağlayan bir yazılımdır. Çoğu işletim sisteminde çalışır, PHP ile yazılmıştır, öncelikle MySQL ve MariaDB veritabanı sunucularını kullanır ve jQuery'yi istemci JavaScript kitaplığı olarak kullanır. MediaWiki'nin geliştirilmesi öncelikle Wikimedia Vakfı tarafından desteklenir, ancak gönüllü topluluk geliştiricileri de büyük bir rol oynamaktadır.

Bu sayfa, MediaWiki'ye katkıda bulunma yolunda başlamanıza yardımcı olmaktadır. Öğretici değil; gerekli olanı öğrenmek için gidebileceğiniz çeşitli yerlere işaret ediyor.

Başlarken
'e kaydolarak ve Gerrit öğreticisini okurken başlayın. Ardından, kodumuzu indirmek, değişiklik yapmak, test etmek ve yamalar göndermek için devam edebilirsiniz. Geliştirme ortamınızı ayarlamanın iki yolu vardır: önceden yapılandırılmış sanal makine kurulumunu (vagrant) veya elle kullanma.

Vagrantlı Sanal Makine

 * Vagrant kurulumu - Bu adımlar MediaWiki sunucusunu bir Linux sanal makinesi içerisindeki tüm gereksinimlerle birlikte yükleyecektir (Linux, Windows veya Mac bilgisayarlarda kullanılabilir)

Elle kurulum

 * Kurulum gereksinimleri — Donanım gereksinimlerini kontrol edin ve bir LAMP, MAMP veya WAMP sunucusu (Linux, Mac veya Windows, ayrıca Apache, MySQL/MariaDB ve PHP) yükleyin.
 * — En son kaynak kodunu Git'ten indirin.
 * - Yükleme ve başlangıç ​​yapılandırmasına devam edin
 * 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.

General recommendations
If you choose to work on a bug report that requires writing or changing code, you might want to at least skim these pages first:

 
 * The two main paths to get started with MediaWiki development are to fix an annoying little bug in the existing code, or to add a new feature, usually through a MediaWiki extension.
 * Coding conventions and any subpages relevant to your task (,, , …)
 * Following the Commit message guidelines, especially the Example section at the bottom, will automatically add a notification about your patch to the corresponding report in . Hence there is no need anymore to add a "Please review" comment in the report.
 * Check your code against the pre-commit checklist. Don't skip this step ; you'll be happy you didn't.
 * Getting code reviews. Find and add people as potential reviewers of your patch.
 * Amending a change. Don't create a new Gerrit changeset to fix your previous one!
 * In most cases when working with MediaWiki, you do not want to hack MediaWiki core unless you really know what you're doing.

Feedback, questions and support
 
 * You are expected to do some basic research yourself first: Look at the code, try to get some understanding what it is supposed to do, read related documentation, try to find the probable place(s) where you need to make changes in order to fix the bug.
 * If you have general questions about infrastructure, the software architecture or workflows which are not tied to the specific bug that you want to work on, use generic channels like, mailing lists, or wiki discussion pages. For example, if you have a problem with Gerrit, the Gerrit discussion page could be a good place to ask.
 * If you have a specific question about the bug itself, comment in the corresponding report. "What do I have to do to fix this bug?" is not a good question to start with: The more specific your questions are, the more likely somebody can answer them quickly. If you have no idea at all how to fix the bug, maybe that bug is not (yet) for you - please consider finding an easier one first.
 * When asking, elaborate what you have tried and found out already, so others can help at the right level. Try to be specific - for example, copy and paste your commands and their output (if not too long) instead of paraphrasing in your own words. This avoids misunderstandings.
 * Avoid private email or support requests in our social media channels.
 * Please be patient when seeking input and comments. On IRC, don't ask to ask, just ask: most questions can be answered by other community members too if you ask on an IRC channel. If nobody answers, please ask on the bug report or wiki page related to the problem; don't just drop the question.
 * Learn more at.

Communicate that you work on a bug
You do not need to be set as the assignee in a bug report or announce your plans before you start working on a bug, but it would be welcome. At the latest when you are close to creating a patch for the bug, it is good to announce in a comment that you are working on it. Your announcement also helps others to not work on the bug at the same time and duplicate work.

Also note that if a bug report already has a recent link to a patch in Gerrit and has the project "Patch-For-Review" associated, you should choose a different bug to work on instead - avoid duplicating work. If the patch in Gerrit has not been merged and has not seen any changes for a long time, you could also pick up that existing patch and try to improve it.

If you stop working on a task you should remove yourself as the assignee of a bug report and reset the assignee to the default assignee, so others know that they can work on the bug report and don't expect you to still work on it.

By communicating early you will get more attention, feedback and help from community members. 

Working on extensions
If you choose to work on MediaWiki extensions code, the following links provide more information.

 * Making a MediaWiki extension — Covers how to develop an extension for Mediawiki, best practices, and how to engage the Mediawiki community. From February 2011.
 * Special page template — Add a special page to display some handy information.
 * Extending wiki markup — Add a parser hook to modify the content of wikitext.

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.

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.
