Roberto Ierusalimschy	1de95e97ef	Bug: Lua stack still active when closing a state	3 years ago
Roberto Ierusalimschy	ad3942adba	Main 'mainposition' replaced by 'mainpositionTV' Handle values in table keys as the special cases they are, and not the other way around.	3 years ago
Roberto Ierusalimschy	48835c76c8	Wrong assert in 'collectvalidlines'	3 years ago
Roberto Ierusalimschy	6b3e116d44	Corrected bug in 'luaD_tryfuncTM' The pointer to the metamethod can be invalidated by a finalizer that can run during a GC in 'checkstackGCp'. (This commit also fixes a detail in the manual.) Bug introduced in commit `91673a8ec`.	3 years ago
Roberto Ierusalimschy	e8deac5a41	Avoid OP_VARARGPREP for active lines when building the table 'activelines' for a vararg function, this first instruction does not make the first line active.	3 years ago
Roberto Ierusalimschy	bfbff3703e	Bug: Wrong status in coroutine during reset When closing variables during 'coroutine.close' or 'lua_resetthread', the status of a coroutine must be set to LUA_OK; a coroutine should not run with any other status. (See assertion in 'lua_callk'.) After the reset, the status should be kept as normal, as any error was already reported.	3 years ago
Roberto Ierusalimschy	74d99057a5	Bug: C stack overflow with coroutines 'coroutine.resume' did not increment counter of C calls when continuing execution after a protected error (that is, while running 'precover').	3 years ago
Roberto Ierusalimschy	1fce5bea81	More uniform implementation for tail calls 'luaD_pretailcall' mimics 'luaD_precall', handling call metamethods and calling C functions directly. That makes the code in the interpreter loop simpler. This commit also goes back to emulating the tail call in 'luaD_precall' with a goto, as C compilers may not do proper tail calls and the C stack can overflow much sooner than the Lua stack (which grows as the metamethod is added to it).	3 years ago
Roberto Ierusalimschy	3699446aaf	Removed goto's in 'luaD_precall' (plus a detail in lauxlib.h.)	3 years ago
Roberto Ierusalimschy	0e5071b5fb	Avoid taking the address of a 'TValue' field That structure can be packed in the future.	3 years ago
Roberto Ierusalimschy	87a9573b2e	Documentation Better explanation about the guaranties of multiple assignment in the manual.	3 years ago
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
