  • 4053eae9eb bug: Lua does not check GC when creating error messages Roberto Ierusalimschy 2017-07-27 10:55:38 -03:00
  • 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 -03:00
  • 11769b203f new version (5.4) Roberto Ierusalimschy 2017-07-27 10:36:54 -03:00
  • b1daa069ba bug: Lua does not check GC when creating error messages Roberto Ierusalimschy 2017-07-10 14:35:12 -03:00

  • 124bfd2081 dumping ints and size_ts compacted Roberto Ierusalimschy 2017-06-27 11:21:12 -03:00
  • 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 -03:00
  • 60a7492d24 new type 'ls_byte' for signed bytes Roberto Ierusalimschy 2017-06-27 08:35:01 -03:00
  • 73ec04fcf3 no more 'DEADKEY'. Table traversals do not need to consider dead keys; if the key is dead, it cannot be given to 'next'. Instead, we now use a 'table' tag without the collectable bit, which makes it a unique tag good enough to reserve space. Roberto Ierusalimschy 2017-06-12 11:21:44 -03:00

  • 4804bbd9bb include first standard header files (Some broken compiler has problems with 'signal.h' being included without a definition for 'size_t'.) Roberto Ierusalimschy 2017-05-24 18:11:19 -03:00

  • 92b3deaffa details in OP_CALL + comments Roberto Ierusalimschy 2017-05-18 16:34:39 -03:00
  • 49f7aab62a 'lua_rawlen' returns 'lua_Unsigned' instead of 'size_t'. (Real length of strings and userdata are limited by Lua integers, but table length is hard to compute limiting it to 'size_t'.) Roberto Ierusalimschy 2017-05-18 09:34:58 -03:00
  • 3d879fbc5d reimplementation of 'luaH_getn', trying to handle numeric limits properly. Roberto Ierusalimschy 2017-05-16 16:07:08 -03:00
