Bug ID: 52592
Summary: mw.clone causes script error when used on a table
returned from mw.loadData
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Scribunto
Assignee: wikibugs-l@lists.wikimedia.org
Reporter: codeca...@gmail.com

The function mw.clone is meant to create a deep copy of a value. mw.loadData
returns read-only tables, so a deep copy is necessary to modify a table
returned from mw.loadData. However, when an attempt is made to clone such a
table, a script error occurs:
table from mw.loadData is read-only
This is obviously not the intended behaviour and it prevents one of the main
uses of mw.clone.
