Roberto Ierusalimschy	e15f1f2bb7	Details Typos in comments and details in the manual.	2 years ago
Roberto Ierusalimschy	7ca8105a2e	More orderliness in casts of enumerations	2 years ago
Roberto Ierusalimschy	413a393e62	Stack indices changed to union's That will allow to change pointers to offsets while reallocating the stack.	2 years ago
Roberto Ierusalimschy	42d40581dd	Save stack space while handling errors Because error handling (luaG_errormsg) uses slots from EXTRA_STACK, and some errors can recur (e.g., string overflow while creating an error message in 'luaG_runerror', or a C-stack overflow before calling the message handler), the code should use stack slots with parsimony. This commit fixes the bug "Lua-stack overflow when C stack overflows while handling an error".	3 years ago
Roberto Ierusalimschy	066e0f93c4	Fix debug information about finalizers The flag CIST_FIN does not mark a finalizer, but the function that was running when the finalizer was called. (So, the function did not call the finalizer, but it looks that way in the stack.)	3 years ago
Roberto Ierusalimschy	48835c76c8	Wrong assert in 'collectvalidlines'	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	87a9573b2e	Documentation Better explanation about the guaranties of multiple assignment in the manual.	3 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	f5df7f91f7	Wrong assertion in 'getbaseline' The assertion cannot compute 'f->abslineinfo[i]' when the initial estimate 'i' is -1.	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	e500892e18	Optimization/simplification of 'getbaseline' By producing absolute line information at regular intervals, a simple division can compute the correct entry for a given instruction.	4 years ago
Roberto Ierusalimschy	949187b049	Optimizations for line hook The function 'changedline' tries harder to avoid calling 'luaG_getfuncline' plus small changes in the use of 'L->oldpc'.	4 years ago
Roberto Ierusalimschy	4bd10b6fe8	Better error messages for calling non-callable objects When available, use the calling code to find a suitable name for what was being called; this is particularly useful for errors of non-callable metamethods. This commit also improved the debug information for order metamethods.	4 years ago
Roberto Ierusalimschy	ae5b5ba529	Fixed bug: line hooks in stripped functions Line-hook handling was accessing debug info. without checking whether it was present.	4 years ago
Roberto Ierusalimschy	a585eae6e7	Fixed bug: Negation overflow in getlocal/setlocal	4 years ago
Roberto Ierusalimschy	a2195644d8	Fixed bug: invalid 'oldpc' when returning to a function The field 'L->oldpc' is not always updated when control returns to a function; an invalid value can seg. fault when computing 'changedline'. (One example is an error in a finalizer; control can return to 'luaV_execute' without executing 'luaD_poscall'.) Instead of trying to fix all possible corner cases, it seems safer to be resilient to invalid values for 'oldpc'. Valid but wrong values at most cause an extra call to a line hook.	4 years ago
Roberto Ierusalimschy	17dbaa8639	Improvements in the handling of signals Added 'volatile' to 'l_signalT' variables plus some minor changes.	5 years ago
Roberto Ierusalimschy	6eb53b7526	Details Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.	5 years ago
Roberto Ierusalimschy	46c3587a6f	Clearer distinction between types and tags LUA_T* represents only types; tags (types + Variants) are represented by LUA_V* constants.	5 years ago
Roberto Ierusalimschy	5ff408d218	Changed internal representation of booleans Instead of an explicit value (field 'b'), true and false use different tag variants. This avoids reading an extra field and results in more direct code. (Most code that uses booleans needs to distinguish between true and false anyway.)	5 years ago
Roberto Ierusalimschy	4518e5df24	Added macro 'testMMMode' Macro 'testMMMode' checks whether opcode is an MM opcode.	5 years ago
Roberto Ierusalimschy	46b84580d6	Use of 'MMBIN' opcodes extended to shift operators Plus, this commit removes useless 'tm' parameters in 'op_*' macros.	5 years ago
Roberto Ierusalimschy	df13f25948	First version of OP_MMBIN opcodes In arithmetic/bitwise operators, the call to metamethods is made in a separate opcode following the main one. (The main opcode skips this next one when the operation succeeds.) This change reduces slightly the size of the binary and the complexity of the arithmetic/bitwise opcodes. It also simplfies the treatment of errors and yeld/resume in these operations, as there are much fewer cases to consider. (Only OP_MMBIN/OP_MMBINI/OP_MMBINK, instead of all variants of all arithmetic/bitwise operators.)	5 years ago
Roberto Ierusalimschy	fe040633a1	Tracebacks recognize metamethods '__close'	5 years ago
Roberto Ierusalimschy	2c68e66570	Details Several small changes from feedback on 5.4 alhpa rc1 (warnings, typos in the manual, and the like)	6 years ago
Roberto Ierusalimschy	5ca1075b71	Added field 'srclen' to structure 'lua_Debug' This new field gets the length of 'source' in the same structure. Unlike the other strings in that structure, 'source' can be relatively large, and Lua already has its length readily available.	6 years ago
Roberto Ierusalimschy	6d04537ea6	A to-be-closed variable must have a closable value (or be nil) It is an error for a to-be-closed variable to have a non-closable non-nil value when it is being closed. This situation does not seem to be useful and often hints to an error. (Particularly in the C API, it is easy to change a to-be-closed index by mistake.)	6 years ago
Roberto Ierusalimschy	84e32ad2eb	Added opcodes for arithmetic with K operands Added opcodes for all seven arithmetic operators with K operands (that is, operands that are numbers in the array of constants of the function). They cover the cases of constant float operands (e.g., 'x + .0.0', 'x^0.5') and large integer operands (e.g., 'x % 10000').	6 years ago
Roberto Ierusalimschy	e073cbc2e5	Better error messages for invalid operands in numeric 'for' "Better" and similar to error messages for invalid function arguments. old message: 'for' limit must be a number new message: bad 'for' limit (number expected, got table)	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	6f2b8e21c4	added 'const' to 'Proto*' when possible	7 years ago
Roberto Ierusalimschy	e64e20ac81	minimizing the code ran by 'vmfetch' + no more 'vra' (the code is simpler without 'vra' and conversion is a no-op)	7 years ago
Roberto Ierusalimschy	4907444db9	'fTransfer' -> 'ftransfer' / 'nTransfer' -> 'ntransfer' (keep the standard of names in lower case)	7 years ago
Roberto Ierusalimschy	422318f677	two new fields 'fTransfer'/'nTransfer' in 'lua_Debug' structure (for information about values being given and returned in function calls)	7 years ago
Roberto Ierusalimschy	b1379936cf	vararg back to '...' (but with another implementation) new implementation should have zero overhead for non-vararg functions	7 years ago
Roberto Ierusalimschy	51280ef2ad	call hooks for Lua functions called by 'luaV_execute'	7 years ago
Roberto Ierusalimschy	728ff94595	error handler in protected calls must be a function	7 years ago
Roberto Ierusalimschy	cf7eff45f3	keep control of stack top in Lua functions concentrated in 'luaV_execute'	7 years ago
Roberto Ierusalimschy	1d5b885437	when running Lua code, there is no need to keep 'L->top' "correct"; set it only when needed.	7 years ago
Roberto Ierusalimschy	b3f924bc69	'Proto->numparams' does not include vararg parameter (one less subtraction when calling functions...)	7 years ago
Roberto Ierusalimschy	86431a2f1c	new opcodes BANDK/BORK/BXORK. (They do not use immediate operands because, too often, masks in bitwise operations are integers larger than one byte.)	7 years ago
Roberto Ierusalimschy	9fa1baf6de	opcodes for order and shift can use several metamethods, so it is better to use a generic description + metamethod names in some error messages shown without '__' prefix	7 years ago
Roberto Ierusalimschy	599f1742c6	detail (typo in comments)	7 years ago
Roberto Ierusalimschy	196c87c9ce	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)	7 years ago
Roberto Ierusalimschy	5440b42f43	using 'trap' to stop 'luaV_execute' when necessary (tracing and to update its copy of 'base' when the stack is reallocated)	7 years ago
Roberto Ierusalimschy	62f3b7c472	detail	7 years ago
Roberto Ierusalimschy	26679ea35b	new function 'luaV_flttointeger' to convert floats to integers (without string coercions) + string operands to bitwise operations handled by string metamethods	7 years ago
Roberto Ierusalimschy	c3e5946fb2	new format for JUMP instructions (to allow larger offsets)	7 years ago
