Will be removed in future lua versions.
Could you add a link to the upstream commit and describe how lua relates to nmap? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Nmap has embedded lua interpreter as a scripting engine. Lua doesn't have development code repository, but this is already fixed in the current development version 5.2.0-alpha, see http://www.lua.org/work/. Here's discussion about this on lua mailing list: http://lua-users.org/lists/lua-l/2009-08/msg00213.html -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
