Request for comment (RFC)

Debugging at production server
Component	General
Creation date	2 June 2014
Author(s)	devunt
Document status	in draft See Phabricator.

Background

Debugging toolbar feature was introduced in MediaWiki 1.19.

Problem

Sometimes we have to debug on production wiki, but don't want to show internal information to normal users.

But the current architecture of debugging toolbar is available for everyone, so some internal information, like the server's directory structure, debug logs, and so on, can be leaked.

Proposal

Make only selected user can use debugging toolbar. Proposed implementation is using user rights (usedebugtoolbar, see Gerrit change 119002).
