  • 4053eae9eb bug: Lua does not check GC when creating error messages Roberto Ierusalimschy 2017-07-27 10:55:38 -0300
  • 6d998055c8 no more reference 'memerrmsg' + new reference to "n" (both can be retrieved by 'luaS_newliteral' without creating anything, because they are fixed, but "n" deserves fast access while 'memerrmsg' does not) Roberto Ierusalimschy 2017-07-27 10:50:16 -0300
  • 11769b203f new version (5.4) Roberto Ierusalimschy 2017-07-27 10:36:54 -0300

  • b42430fd3a 'lineinfo' in prototypes saved as differences instead of absolute values, so that the array can use bytes instead of ints, reducing its size. (A new array 'abslineinfo' is used when line differences do not fit in a byte.) Roberto Ierusalimschy 2017-06-27 08:35:31 -0300

  • 73ec04fcf3 no more 'DEADKEY'. Table traversals do not need to consider dead keys; if the key is dead, it cannot be given to 'next'.
