This article is written to help developers learn the basic skills needed to contribute to development of MediaWiki core and MediaWiki extensions. Note that in most cases when working with MediaWiki, you do not want to hack MediaWiki core unless you really know what you're doing.

The main path to get started with Wikimedia development is to contribute to Wikimedia projects that offer mentoring. An alternative without mentoring is to fix a good first bug.

If you are an experienced developer who is familiar with using MediaWiki already, visit the Developer hub instead.

For other ways to get involved in the Wikimedia community, see কিভাবে অবদান রাখবো .

সংক্ষিপ্ত বিবরণ

MediaWiki is the software that powers Wikipedia, its sister projects and thousands of wikis all over the world.

MediaWiki is written in the PHP programming language[1]. এটি জাভাস্ক্রিপটের ক্লায়েন্ট লাইব্রেরি হিসাবে যেকোয়ারি ব্যবহার করে।

MediaWiki is primarily written for the LAMP platform[2] and runs on most operating systems. MediaWiki primarily uses the MySQL or MariaDB database servers.[3]

Development happens in an open source style[4], is largely coordinated online, and supported by the Wikimedia Foundation, though volunteer community developers play a huge part as well.

এই পৃষ্ঠাটি আপনাকে মিডিয়াউইকিতে একজন অবদানকারী হতে সাহায্য করবে। It is not a tutorial; it just points you to various places where you can go learn whatever is necessary.

আপনার উন্নয়নের পরিবেশ তৈরী করুন

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 (Vagrant or Docker), or a manual configuration approach.

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).

Docker development environment

ম্যানুয়াল ইনস্টল

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.

Suggested reading

Watch as a developer fixes a bug in a MediaWiki extension, including investigation, git commit, getting it reviewed and merged, and closing the Bugzilla ticket (now replaced by ফ্যাব্রিকেটর ).

প্রতিক্রিয়া, প্রশ্ন এবং সমর্থন

  • 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 which are not tied to the specific task that you want to work on, use generic channels like Wikimedia Developer Support, IRC or mailing lists but not the specific task.
  • If you have a specific question about the bug itself, comment in the corresponding bug report (normally a task in ফ্যাব্রিকেটর ). "Can you give me more info how 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, explain what you have tried and found out already, so others can help at the right level. 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.
  • 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 give up.
  • Learn more at যোগাযোগ .
  • You can also ask any questions at the weekly Technical Advice IRC Meeting on the #wikimedia-tech channel on Freenode IRC.



Communicate that you work on a task

Do not ask if you can work on a task. You do not need to announce your plans before you start working on a bug, but it would be welcome. You are welcome to set yourself as the assignee in a task: Use the dropdown Add Action… → Assign/Claim in Phabricator. At the latest when you are close to proposing a patch for the task, it is good to announce in a comment that you are working on it. Your announcement helps others to not work on the bug at the same time and to not duplicate work.

Also note that if a task already has a recent link to a patch in Gerrit and has the project "Patch-For-Review" associated in Phabricator, choose a different task to work on instead - avoid duplicating work. If an existing 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 improve it, based on the feedback in Gerrit and in the task.

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

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

PHP

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

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


তথ্যভান্ডার

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

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.

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.

  1. ↑ Not all of MediaWiki is written in PHP. Some supporting tools are written in other languages, including batch files, shell scripts, makefiles and Python.
  2. ↑ MediaWiki runs on most platforms that can support PHP, however, the lack of certain utilities or operating system features may limit the functionality or performance of MediaWiki on non-LAMP platforms.
  3. ↑ MediaWiki has support for DBMS other than MySQL and MariaDB, including Oracle, PostgreSQL, SQLite, and Microsoft SQL Server.
  4. ↑ Developers are a mix of volunteers and paid staff (or contractors) for various organizations. For a full list of who works on the MediaWiki code, read the Developers article.
  5. ↑ Browse the source code and revisions of code repositories at https://phabricator.wikimedia.org/diffusion/ or download the source code to your system by using Gerrit.
