[d766e2ae] first (parcial) implementation of 'keyin'/'removekey' (still no metamethods, no raw verssions) (Roberto Ierusalimschy)
[f055a9df] added check in 'obj2gco' to prevent its use in non Lua-object pointers (otherwise its cast is blind, casting any value given to it) (Roberto Ierusalimschy)
[4a7fe618] in 'clearbykeys', clear keys of just-removed entries too (Roberto Ierusalimschy)
[9243c414] first version of empty entries in tables (so that, in the future, tables can contain regular nil entries) (Roberto Ierusalimschy)
[477ca2fe] some reorganization in 'lobject.h' (just moving stuff around) (Roberto Ierusalimschy)

[194a4f97] small simplifications in 'luaD_poscall' (Roberto Ierusalimschy)
[196c87c9] no more 'stackless' implementation; 'luaV_execute' calls itself recursively to execute function calls. 'unroll' continues all executions suspended by an yield (through a long jump) (Roberto Ierusalimschy)
[39f26b14] more information from 'T.stacklevel' (Roberto Ierusalimschy)
[3c230cc8] using 'A' for register instead of 'B' in relational opcodes ('R(A)' is already created by default for all instructions.) (Roberto Ierusalimschy)

[4053eae9] bug: Lua does not check GC when creating error messages (Roberto Ierusalimschy)
[6d998055] 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)

[124bfd20] dumping ints and size_ts compacted (Roberto Ierusalimschy)

[60a7492d] new type 'ls_byte' for signed bytes (Roberto Ierusalimschy)
[73ec04fc] 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)

[92b3deaf] details in OP_CALL + comments (Roberto Ierusalimschy)
[49f7aab6] '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)
[3d879fbc] reimplementation of 'luaH_getn', trying to handle numeric limits properly. (Roberto Ierusalimschy)
[6d95de83] no more field 'base' in CallInfo (base is always equal to 'func + 1', with old/new vararg implementation) (Roberto Ierusalimschy)
[5c8770f8] back to old-style vararg system (with vararg table collecting extra arguments) (Roberto Ierusalimschy)
[7647d5d1] revamp of fast track for table access (table set uses the same macros as table get + new macro for integer keys) (Roberto Ierusalimschy)

[dbb6f11e] bug (with compat on): 'ipairs' can work with any type that provides an __index; so, 'pairsmeta' should not check for tables. ('pairs' already checks for tables through 'next'.) (Roberto Ierusalimschy)

[0232fbff] now that 'luaO_str2num' always accepts a dot as a radix character, the lexer does not need to bother with this issue. (Roberto Ierusalimschy)

[8d4feb50] do not try to ensure that 'sweepgc' points to a live object when entering sweep phase ('entersweep'); that may be too expensive to be done still inside the atomic step. Walking one single object more often than not will work. (Roberto Ierusalimschy)

[1f259be5] 'getcode' -> 'getinstruction' (Roberto Ierusalimschy)

[e3839416] in 'table.sort': 'typedef' for type of indices + removed stack check (recursion is in the C stack, not in the Lua stack!) (Roberto Ierusalimschy)

[ffd0d123] using more "conventional" loops in 'luaD_poscall' (probably a little more efficient?) (Roberto Ierusalimschy)
[07a2dcac] flag CIST_REENTRY changed to CIST_FRESH (its negation); fresh invocations seem to be less frequent than reentries. (So, avoid setting flag on the frequent case.) (Roberto Ierusalimschy)
[c874abac] with 'fast tracks', there is no need to do raw accesses in 'ipairs' (Roberto Ierusalimschy)
[789e423b] corrected comparisons of signed (int) with unsigned (size_t) (Roberto Ierusalimschy)

[cc3a42b1] option 'c' in 'string.pack' accepts any string size (truncating if larger and padding if smaller) (Roberto Ierusalimschy)
[6707ce63] function prepares vararg only if it really uses them (chunks are always declared vararg but seldom uses them) (Roberto Ierusalimschy)

[82129b92] use macro 'hasjumps' to test whether expression has jumps... (Roberto Ierusalimschy)
[8004ab75] hook test in 'luaV_execute' reduced to minimum (rest done in 'luaG_traceexec'; no difference in performance for the non-hook case, but keeps 'luaV_execute' a little simpler) + 'base' updates replaced by 'Protect' (which serves this rule) (Roberto Ierusalimschy)

[75d5a892] macro 'addbuff' was using external variable name, instead of using its parameter name inside the macro. (Roberto Ierusalimschy)
[880f82d0] '*' as a number means stack size, so that "return *" returns all values in the stack. (Roberto Ierusalimschy)

[ee5edb6b] macros 'getaddrstr' and 'getstr' unified (they do the same thing) (Roberto Ierusalimschy)

[364cdbdb] 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache' is not needed in the fast track (as it does not create new entries) + small bug in 'auxsetstr' (calling barrier with wrong object) + using 'setobj2t' without side effects in its arguments (Roberto Ierusalimschy)

[6556fcfe] small janitor work (Roberto Ierusalimschy)

[502214f8] added assert for NULL pointer in 'lua_pushlstring' (Roberto Ierusalimschy)
[ed19fe76] added ';' at the end of "expression lines" ("return exp;") so that an extra ";" at the end is enough to stop Lua printing the result ("return exp;;" is not valid) (Roberto Ierusalimschy)

[ec79f252] new lua function "getstack"; new interface to function luaI_reportbug. (Roberto Ierusalimschy)
[18ea2eff] calls to "lua_reportbug" changed to "lua_error", since "lua_reportbug" is only an internal function to build debug information (Roberto Ierusalimschy)
[81566048] run-time stack now is controled at run time, instead of compilation time. (Waldemar Celes)
[36b6fdda] function "type" now returns a second result: the tag of the type, so lua can discriminate different kinds of user data. (Roberto Ierusalimschy)

[572ee14b] use yacc++ instead of yacc. (Roberto Ierusalimschy)
