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	26be27459b	Negation in constant folding of '>>' may overflow	2 years ago
Roberto Ierusalimschy	d61b0c6028	More checks and documentation for uses of EXTRA_STACK	2 years ago
Roberto Ierusalimschy	8dd2c912d2	Detail Warnings with clang when using long double for Lua floats.	3 years ago
Roberto Ierusalimschy	58216600eb	'luaL_newstate' should not allocate extra memory The allocation of a userdata for the state of the warn system can cause a panic if it fails; 'luaL_ref' also can fail. This commit re-implements the warn system so that it does not need an explicit state. Instead, the system uses different functions to represent the different states.	4 years ago
Roberto Ierusalimschy	0280407fc5	Details Comments in makefile and function 'l_str2d'.	4 years ago
Roberto Ierusalimschy	ae809e9fd1	'luaV_concat' can "concat" one single value Several of its callers needed that case and had to do the check themselves.	4 years ago
Roberto Ierusalimschy	e96385aded	Simplification and smaller buffers for 'lua_pushfstring' The function 'lua_pushfstring' is seldom called with large strings, there is no need to optimize too much for that cases.	4 years ago
Roberto Ierusalimschy	72a094bda7	Undo change in the handling of 'L->top' (commit `b80077b8f3`) With MMBIN instructions, there are fewer opcodes that need to update 'L->top', so that change does not seem to pay for the increased complexity.	5 years ago
Roberto Ierusalimschy	b80077b8f3	Change in the handling of 'L->top' when calling metamethods Instead of updating 'L->top' in every place that may call a metamethod, the metamethod functions themselves (luaT_trybinTM and luaT_callorderTM) correct the top. (When calling metamethods from the C API, however, the callers must preserve 'L->top'.)	5 years ago
Roberto Ierusalimschy	1fb4d53925	OP_NEWTABLE keeps exact size of arrays OP_NEWTABLE is followed by an OP_EXTRAARG, so that it can keep the exact size of the array part of the table to be created. (Functions 'luaO_int2fb'/'luaO_fb2int' were removed.)	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	b293ae0577	Details - new error message for "attempt to assign to const variable" - note in the manual about compatibility options - comments - small changes in 'read_line' and 'pushstr'	6 years ago
Roberto Ierusalimschy	7c5786479c	A few more improvements in 'luaO_pushvfstring' - 'L' added to the 'BuffFS' structure - '%c' does not handle control characters (it is not its business. This now is done by the lexer, who is the one in charge of that kind of errors.) - avoid the direct use of 'l_sprintf' in the Lua kernel	6 years ago
Roberto Ierusalimschy	b36e26f51b	Some more small improvements to 'luaO_pushvfstring' Details: - counter 'pushed' moved to the struct 'BuffFS' - new auxiliar function 'getbuff' to build strings directly on the buffer.	6 years ago
Roberto Ierusalimschy	3da34a5fa7	Revamp of 'lua_pushfstring' / 'luaO_pushvfstring' The function 'luaO_pushvfstring' now uses an internal buffer to concatenate small strings, instead of pushing all pieces on the stack. This avoids the creation of several small Lua strings for each piece of the result. (For instance, a format like "n: '%d'" used to create three intermediate strings: "n: '", the numeral, and "'". Now it creates none.)	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	1e0c73d5b6	Changes in the validation of UTF-8 All UTF-8 encoding functionality (including the escape sequence '\u') accepts all values from the original UTF-8 specification (with sequences of up to six bytes). By default, the decoding functions in the UTF-8 library do not accept invalid Unicode code points, such as surrogates. A new parameter 'nonstrict' makes them accept all code points up to (2^31)-1, as in the original UTF-8 specification.	6 years ago
Roberto Ierusalimschy	5e76a4fd31	New macros for arithmetic/bitwise operations in 'luaV_execute' The repetitive code of the arithmetic and bitwise operators in the main iterpreter loop was moved to appropriate macros. (As a detail, the function 'luaV_div' was renamed 'luaV_idiv', as it does an "integer division" (floor division).	6 years ago
Roberto Ierusalimschy	5382a22e0e	Corrections in the implementation of '%' for floats. The multiplication (m*b) used to test whether 'm' is non-zero and 'm' and 'b' have different signs can underflow for very small numbers, giving a wrong result. The use of explicit comparisons solves this problem. This commit also adds several new tests for '%' (both for floats and for integers) to exercise more corner cases, such as very large and very small values.	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	505fc91222	no more 'luaO_nilobject' to avoid comparison of global variable addresses (now uses static variables)	7 years ago

Roberto Ierusalimschy	10b0b09555	do not convert decimal constants with overflow to integers. (Therefore, they will be converted as floats)	9 years ago
Roberto Ierusalimschy	ed110f66c5	'luaO_str2num' (and, therefore, 'lua_stringtonumber', 'number', and coercions) accepts both the locale point and a dot as its radix character	9 years ago
Roberto Ierusalimschy	2d1d57bc18	comments	9 years ago
Roberto Ierusalimschy	8c1fb91802	macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used in critical time pathes, can save a few bytes without the macro)	9 years ago
