Bug ID: 50919
Summary: Error for invalid on-wiki JavaScript can show wrong
filename
Product: MediaWiki
Version: 1.22-git
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: Unprioritized
Component: ResourceLoader

When on-wiki JavaScript fails JSMin's (JSParser to be exact) validation, it
makes the minified script file just throw an error. This error thrown includes
the page name (e.g. User:Example/common.js).
This output is cached, which means if someone copies the JavaScript (e.g. to
debug the problem), it will show the wrong filename/page name for that
subsequent user.
This usually won't be too hard for a user to figure out (particularly if
there's only one copy). However, the page name could be added to the cache key
to fix this. I don't think this will have too much of a performance impact.
There generally shouldn't be many identical copies of a script (there are
certainly scripts widely imported, though).
