Roberto Ierusalimschy	deac067ed3	Avoid overflows when incrementing parameters in C Any C function can receive maxinteger as an integer argument, and therefore cannot increment it without some care (e.g., doing unsigned arithmetic as the core does).	3 years ago
Roberto Ierusalimschy	2ff3471722	Using 'inline' in some functions According to ISO C, "making a function an inline function suggests that calls to the function be as fast as possible." (Not available in C89.)	3 years ago
Roberto Ierusalimschy	9db4bfed6b	Revamp of format validation in 'string.format' When calling 'sprintf', not all conversion specifiers accept all flags; some combinations are undefined behavior.	3 years ago
Roberto Ierusalimschy	91673a8ec0	'luaD_tryfuncTM' checks stack space by itself	3 years ago
Roberto Ierusalimschy	41871f1803	Undo simplification of tail calls (commit `901d760`) Not that simpler and slower.	3 years ago
Roberto Ierusalimschy	a393ac2554	Detail in 'testes/math.lua' Added a print with the random seeds used in the tests of 'random'.	3 years ago
Roberto Ierusalimschy	65434b4d1b	Option '-l' can give a name for the global variable. Sintax for this option now is '-l [globname=]modname'.	3 years ago
Roberto Ierusalimschy	59acd79c05	Added tests for string reuse by the scanner	3 years ago
Roberto Ierusalimschy	e2c07dcbf7	Improved documentation for 'lua_getinfo'	3 years ago
Roberto Ierusalimschy	439e45a2f6	Bug: luaL_tolstring may get confused with negative index When object has a '__name' metafield, 'luaL_tolstring' used the received index after pushing a string on the stack.	3 years ago
Roberto Ierusalimschy	62fb934427	Bug: Negation in 'luaV_shiftr' may overflow Negation of an unchecked lua_Integer overflows with mininteger.	3 years ago
Roberto Ierusalimschy	8a32e0aa4a	Correction on documentation of string-buffer operations All string-buffer operations can potentially change the stack in unspecified ways; the push/pop documentation in the manual should reflect that.	3 years ago
Roberto Ierusalimschy	dbdc74dc55	Simplification in the parameters of 'luaD_precall' The parameters 'nresults' and 'delta1', in 'luaD_precall', were never meaningful simultaneously. So, they were combined in a single parameter 'retdel'.	3 years ago
Roberto Ierusalimschy	6a0dace25a	Bug: 'local function' can assign to '<const>' variables	3 years ago
Roberto Ierusalimschy	04e19712a5	C functions can be tail called, too A tail call to a C function can have the behavior of a "real" tail call, reusing the stack frame of the caller.	3 years ago
Roberto Ierusalimschy	901d760093	Simpler implementation for tail calls Tail calls handled by 'luaD_precall', like regular calls, to avoid code duplication.	3 years ago
Roberto Ierusalimschy	c0ed74c1e1	Avoid the term "undefined behavior" in the manual	3 years ago
Roberto Ierusalimschy	fc6c74f100	'index2value' more robust 'index2value' accepts pseudo-indices also when called from a Lua function, through a hook.	4 years ago
Roberto Ierusalimschy	1e6918d553	Details - Removed unused (and trivial) definition LUA_UNSIGNEDBITS - Alignment structure in pack/unpack moved to a narrower scope	4 years ago
Roberto Ierusalimschy	681297187e	Bug: yielding in '__close' mess up number of returns Yielding in a __close metamethod called when returning vararg results changes the top and so messes up the number of returned values.	4 years ago
Roberto Ierusalimschy	5148954eed	Align error messages for calling non-callable values 'pcall(foo)' message was "attempt to call a table value", while 'pcall(function () foo() end) message was "global 'foo' is not callable".	4 years ago
Roberto Ierusalimschy	d205f3a484	Bug: Lua source should not use C99 comments ("//")	4 years ago
Roberto Ierusalimschy	47cffdc723	Bug: tbc variables in "for" loops don't avoid tail calls	4 years ago
Roberto Ierusalimschy	36de01d988	Changes in cache for function constants In 'lcode.c', when adding constants to the list of constants of a function, integers represent themselves in the cache and floats with integral values get a small delta to avoid collision with integers. (This change avoids creating artificial addresses; the old implementation converted integers to pointers to index the cache.)	4 years ago
Roberto Ierusalimschy	7fbe215808	New hash function for integer keys When integer keys do not form a sequence, it is better to use all their bits to compute their hashes. (The previous implementation was quite bad for integer keys with common lower bits, and disastrous for integer keys changing only in their upper 32 bits.)	4 years ago
Roberto Ierusalimschy	bf10593a3a	Allow yields inside '__pairs'	4 years ago
Roberto Ierusalimschy	bef250eb8d	Details Comments and small improvements in the manual.	4 years ago
Roberto Ierusalimschy	ba81adaad9	Next release number (5.4.4)	4 years ago
Roberto Ierusalimschy	eadd8c7178	Added option LUA_NOBUILTIN This option allows external code to avoid the use of gcc builtin macro '__builtin_expect' in the Lua API.	4 years ago
Roberto Ierusalimschy	014daf43cb	Details Comments and order of hashing macros in 'ltable.c'.	4 years ago
Roberto Ierusalimschy	05b13651f9	File 'tracegc.lua' added to 'packtests'	4 years ago
Roberto Ierusalimschy	81c6021fb4	New implementation for 'tbclist' - Fixes a bug, by removing dummy nodes together with the node itself. (The previous implementation could leave dummy nodes in frames which otherwise had no tbc variables, and therefore would not close variables; that could leave 'tbclist' pointing higher than 'top', which could dangle if the stack shrank.) - Computes MAXDELTA based on the type of delta, to ease changing its type if needed. - Instead of 'isdummy', uses 'delta==0' to signal dummy nodes. (Dummy nodes always have MAXDELTA for their real delta.)	4 years ago
Roberto Ierusalimschy	a7b8b27dd3	Uses of "likely" in macros active to all users The use of 'l_likely' in auxlib macros 'luaL_argcheck' and 'luaL_argexpected' should not be restricted to Lua's own code. For that, 'l_likely' was renamed to 'luai_likely' to be exported to external code.	4 years ago
Roberto Ierusalimschy	511d53a826	lua_settop/lua_pop closes to-be-closed variables The existence of 'lua_closeslot' is no reason for lua_pop not to close to-be-closed variables too. It is too error-prone for lua_pop not to close tbc variables being popped from the stack.	4 years ago
Roberto Ierusalimschy	f5df7f91f7	Wrong assertion in 'getbaseline' The assertion cannot compute 'f->abslineinfo[i]' when the initial estimate 'i' is -1.	4 years ago
Roberto Ierusalimschy	e7803f7dbc	New release number (5.4.3)	4 years ago
Roberto Ierusalimschy	b7eb21c1ef	Normalization of metamethod typography in the manual	4 years ago
Roberto Ierusalimschy	cf23a93d82	Added assertions for proper use of string buffers	4 years ago
Roberto Ierusalimschy	9a2de786de	Stack check in warning function for tests The warning function using for tests need to check the stack before pushing anything. (Warning functions are not expected to access a Lua state, therefore they have no preallocated stack space.)	4 years ago
Roberto Ierusalimschy	5276973224	New test module 'tracegc' New module easies the inclusion of GC tracing in individual test files.	4 years ago
Roberto Ierusalimschy	f9d857a81b	Stack reallocation done in two phases $he stack reallocation is done in two steps (allocation + free) because the correction of the pointers pointing into the stack must be done while both addresses (the old stack and the new one) are valid. In ISO C, any pointer use after the pointer has been deallocated is undefined behavior. The compiler option '-fsanitize=pointer-subtract' (plus what it needs to work) complained about the old implementation.	4 years ago
Roberto Ierusalimschy	1537d6680b	New control for reentrancy of emergency collections Instead of assuming that shrinking a block may be an emergency collection, use an explicit field ('gcstopem') to stop emergency collections while GC is working.	4 years ago
Roberto Ierusalimschy	e0260eb2d4	Bug (kind of) in 'isinstack' The function 'isinstack' tried to work around the undefined behavior of subtracting two pointers that do not point to the same object, but the compiler killed to trick. (It optimizes out the safety check, because in a correct execution it will be always true.)	4 years ago
Roberto Ierusalimschy	5205f073c5	Don't use tointegerns when luaV_tointegerns will do Some places don't need the "fast path" macro tointegerns, either because speed is not essential (lcode.c) or because the value is not supposed to be an integer already (luaV_equalobj and luaG_tointerror). Moreover, luaV_equalobj should always use F2Ieq, even if Lua is compiled to "round to floor".	4 years ago
Roberto Ierusalimschy	31925e4cc2	Details Added documentation and asserts that constants for arithmetic opcodes must be numbers.	4 years ago
Roberto Ierusalimschy	59c88f846d	Broadening the use of branch hints More uses of macros 'likely'/'unlikely' (renamed to 'l_likely'/'l_unlikely'), both in range (extended to the libraries) and in scope (extended to hooks, stack growth).	4 years ago
Roberto Ierusalimschy	c03c527fd2	Bug: 'string.concat' error message uses wrong format	4 years ago
Roberto Ierusalimschy	38cc7d40a4	Bug: cannot allow the call 'debug.getinfo(0, ">")' A 'what' argument starting with '>' indicates that there is a function in the C stack, which won't be there if the first argument is not a function.	4 years ago
Roberto Ierusalimschy	bc970005ce	'__close' methods can yield in the return of a C function When, inside a coroutine, a C function with to-be-closed slots return, the corresponding metamethods can yield. ('__close' metamethods called through 'lua_closeslot' still cannot yield, as there is no continuation to go when resuming.)	4 years ago
Roberto Ierusalimschy	f79ccdca9b	Eases the use of clang in the makefile New definition in the makefile for warnings that are valid for gcc but not for clang (CWARNGCC).	4 years ago
