Prevent the accidental escaping of globals with Lua plugins (13.35 KB, patch)

Description Garrett Regier 2015-01-07 21:34:14 UTC 
It is very easy to create globals by accident in Lua, we should implement strict mode. This must be done before a new stable version is released.

Example: http://metalua.luaforge.net/src/lib/strict.lua.html

Prevent the accidental escaping of globals with Lua plugins

This implements a strict mode which prevents the creation of globals, except when using rawset(). This can be disabled for incompatible code by setting __STRICT to false.
Comment 2 Garrett Regier 2015-02-14 20:33:19 UTC 
This problem has been fixed in the unstable development version. The fix will be available in the next major software release. You may need to upgrade your Linux distribution to obtain that newer version.
