Good first bugs

This page is meant to be a curated list of bugs that are relatively easy for a new MediaWiki coder to fix, or tiny features you could add. These are a good way to start getting familiar with the MediaWiki code base.

Relevant Bugzilla queries:
 * bugs with the "easy" keyword
 * bugs with the "easy" keyword sorted by most votes

Defects to fix

 * Random occurrences of "svn" and "phase3" in code
 * We used to use Subversion and our code path included words like |phase3|trunk&sr=1 "trunk" and "phase3" and "svn". Now we use Git and ought to make sure the MediaWiki codebase no longer refers to those old paths. See Carl Fürstenberg's comment for the list of files to change.  It's ok to just start by changing one or two.
 * Add PLURAL support for MediaWiki:Recordadmin-notset
 * The RecordAdmin extension lets you link HTML forms to wiki templates, to give you the ability to keep records in a MediaWiki installation. Source code.
 * Make cite expand template arguments inside &lt;ref&gt;'s.
 * Requires passing the  to  .  Look in the codebase of the Cite extension.
 * Diffs on recent changes feed should have the same formatting of the on wiki diffs
 * Look at  (file) and at   (file).
 * See Parsoid TODO

System messages
System messages often need small corrections to the English text, but the source text can only be changed in the code by developers, contrary to translations; this has grown into a large backlog of usually very easy fixes (which might be as easy as fixing a typo).

Also, many messages are unclear and require better documentation (see Localisation if you're not convinced this is crucial). Missing documentation can also be added by just editing the  subpage of the message on translatewiki.net, like all translations, but may require some study of the code to understand what a message is for: it's therefore optimal to start understanding the code, and very useful for the translators (which don't have such skills).

All the simple issues of this sort are (or should be) listed at the tracking bug 38638 as blockers: pick one and start committing patches!

Little enhancements to add

 * Add block-options to Special:CentralAuth
 * In the CentralAuth extension (source), figure out how to add the user's block options to the section "Blocked status". Talk with us in the #mediawiki channel on FreeNode IRC.
 * Document all configuration variables (usable in LocalSettings.php)
 * Look at the source. It's okay to start by just adding one comment.
 * "Replace all" is very slow: WikiEditor should do a one-step replace when replacing all occurrences
 * make Special:Whatlinkshere includable
 * See Parsoid TODO
