This task is rather boring, but it can be a useful exercise to learn setting up and using Gerrit (our code review tool).
In many MediaWiki extension there are still some old http:// links to www.mediawiki.org. They should use https:// instead.
- Clone the code repository of a MediaWiki extension
- Find all the http links to mediawiki.org and change them to https
- Note: Do not change values of namespace schema definitions (for example values for xmlns, xsi:schemaLocation, targetNamespace should not be changed).
- Submit a patch in Wikimedia Gerrit. See https://www.mediawiki.org/wiki/Gerrit/Tutorial for how to set up Git and Gerrit. Make sure to follow https://www.mediawiki.org/wiki/Gerrit/Commit_message_guidelines and list the Phabricator ticket/bug T189687.
To find http links across several code repositories, you can use
