Roberto Ierusalimschy	fd0e1f530d	Added option for direct correction of stack pointers The use of a pointer (not access, only for computations) after its deallocation is forbiden in ISO C, but seems to work fine in all platforms we are aware of. So, using that to correct stack pointers after a stack reallocation seems safe and is much simpler than the current implementation (first change all pointers to offsets and then changing the offsets back to pointers). Anyway, for now that option is disabled.	3 months ago
Roberto Ierusalimschy	75620b45ae	'lcode.c' can use 'checklimit', too	3 months ago
Roberto Ierusalimschy	3e88b72b8e	A return can have at most 254 values	3 months ago
Roberto Ierusalimschy	8b752ddf14	Bug: wrong code gen. for indices with comparisons In function 'luaK_exp2val', used to generate code for indices: Macro 'hasjumps' does not consider the case when the whole expression is a "jump" (a test). In all other of its uses, the surrounding code ensures that the expression cannot be VJMP.	3 months ago
Roberto Ierusalimschy	1bf4b80f1a	Floats formatted with "correct" precision Conversion float->string ensures that, for any float f, tonumber(tostring(f)) == f, but still avoiding noise like 1.1 converting to "1.1000000000000001".	3 months ago
Roberto Ierusalimschy	4c6afbcb01	Struct 'transferinfo' moved to "lua_State" That reduces the size of "CallInfo". Moreover, bit CIST_HOOKED from call status is not needed. When in a hook, 'transferinfo' is always valid, being zero when the hook is not call/return.	3 months ago
Roberto Ierusalimschy	f2206b2abe	'-Wconversion' extended to all options of Lua numbers	3 months ago
Roberto Ierusalimschy	0acd55898d	Added gcc option '-Wconversion' No warnings for standard numerical types. Still pending alternative numerical types.	3 months ago
Roberto Ierusalimschy	15231d4fb2	'nresults' moved into 'callstatus' That gives us more free bits in 'callstatus', for future use.	4 months ago
Roberto Ierusalimschy	f407b3c4a1	Using CIST_CLSRET instead of trick with 'nresults' The callstatus flag CIST_CLSRET is used in all tests for the presence of variables to be closed in C functions.	4 months ago
Roberto Ierusalimschy	a546138d15	Explicit limit for number of results in a call The parameter 'nresults' in 'lua_call' and similar functions has a limit of 250. It already had an undocumented (and unchecked) limit of SHRT_MAX, but it is seldom larger than 2.	4 months ago
Roberto Ierusalimschy	cd4de92762	Maximum stack size may not fit in unsigned short Therefore, fields ftransfer/ntransfer in lua_Debug must have type 'int'. (Maximum stack size must fit in an 'int'.) Also, this commit adds check that maximum stack size respects size_t for size in bytes.	4 months ago
Roberto Ierusalimschy	6b45ccf4ed	Removed compatibility with "= exp" in the REPL	4 months ago
Roberto Ierusalimschy	93fd6892f8	Fixed bug in 'multiline' 'incomplete' was popping error message that should be used in case there is no more lines to complete the input, that is, 'pushline' returns NULL, due to end of file.	4 months ago
Roberto Ierusalimschy	193bf7919e	'printstack' (from ltests.c) made public That function is useful for debugging the API.	4 months ago
Roberto Ierusalimschy	366c855648	lua.c loads 'readline' dynamically (See comments in luaconf.h.) This change allows easier compilation, as Lua compiles and works even if the package 'readline' is absent from the system. Moreover, non-interactive uses don't load the library, making the stand-alone slightly faster for small loads.	4 months ago
Roberto Ierusalimschy	781219dbe1	Small changes in casts from void* to functions Macro moved to llimits.h, and casts from void* to lua_CFunction first go through 'voidf' (a pointer to a function from void to void), a kind of void* for functions.	4 months ago
Roberto Ierusalimschy	d71fbc3175	Updated dependencies in the make file Mainly to include 'llimits.h' in the non-kernel files	4 months ago
Roberto Ierusalimschy	c403e456b6	New instruction format for SETLIST/NEWTABLE New instruction format 'ivABC' (a variant of iABC where parameter vC has 10 bits) allows constructors of up to 1024 elements to be coded without EXTRAARG.	4 months ago
Roberto Ierusalimschy	6ac7219da3	'isIT'/'isOT' turned from macros to functions	4 months ago
Roberto Ierusalimschy	9904c253da	Flexible limit for use of registers by constructors Instead of a fixed limit of 50 registers (which, in a bad worst case, can limit the nesting of constructors to 5 levels), the compiler computes an individual limit for each constructor based on how many registers are available when it runs. This limit then controls the frequency of SETLIST instructions.	4 months ago
Roberto Ierusalimschy	fb7e5b76c9	Clearer code for controlling maximum registers Plus, added a test to check that limit.	4 months ago
Roberto Ierusalimschy	c1dc08e8e8	Length of external strings must fit in Lua integer (As the length of any string in Lua.)	5 months ago
Roberto Ierusalimschy	0f7025dcae	Details in the manual	5 months ago
Roberto Ierusalimschy	ef28e5f789	Removed 'int' size limit for string.rep	5 months ago
Roberto Ierusalimschy	ec65ab878e	Removed 'int' size limit for pack/unpack	5 months ago
Roberto Ierusalimschy	e24ce8c2b3	lua_writestring & co. moved to llimits.h They don't need to be visible by clients of Lua.	5 months ago
Roberto Ierusalimschy	a08d82eb13	llimits.h being used by all Lua code The definitions in llimits.h are useful not only for the core. That header only defines types and '#define's, so libs and core still do not share any real code/data.	5 months ago
Roberto Ierusalimschy	55ac40f859	Cleaning of llimits.h Several definitions that don't need to be "global" (that is, that concerns only specific parts of the code) moved out of llimits.h, to more appropriate places.	5 months ago
Roberto Ierusalimschy	97ef8e7bd4	GC test was not restarting collector after pause	5 months ago
Roberto Ierusalimschy	aaf3533653	Tricky _PROMPT may trigger undefined behavior in lua.c	5 months ago
Roberto Ierusalimschy	b529aefc53	Bug: luaL_traceback may need more than 5 stack slots	5 months ago
Roberto Ierusalimschy	d51022bf9e	Bug: overlapping assignments ISO C forbids assignment of a union field to another field of the same union.	5 months ago
Roberto Ierusalimschy	bb7bb5944c	More disciplined use of 'errno' Set errno to zero before calling any function where we may use its errno, and check errno for zero before using it (as functions may not set it even in error). The code assumes that no function will put garbage on errno (although ISO C allows that): If any function during an operation set errno, and the operation result in an error, assume that errno has something to say.	5 months ago
Roberto Ierusalimschy	94b503d95e	Encoding of table indices (hres) must use C indices As the encoding of array indices is (~index), 0 is encoded as -1 and INT_MAX is encoded as INT_MIN.	5 months ago
Roberto Ierusalimschy	bdc85357aa	Bug: Active-lines for stripped vararg functions Lua seg. faults when asked to create the 'activelines' table for a vararg function with no debug information.	5 months ago
Roberto Ierusalimschy	b291008cc2	Manual for 'string.format' lists what it accepts Instead of listing what it does not accept, which is always relative.	5 months ago
Roberto Ierusalimschy	814213b65f	utf8.offset returns also final position of character 'utf8.offset' returns two values: the initial and the final position of the given character.	5 months ago
Roberto Ierusalimschy	cbdf4969ec	Manual: errors in lua_toclose are not memory errors	6 months ago
Roberto Ierusalimschy	262dc5729a	Details Corrections in comments and manual. Added note in the manual about local variables in the REPL.	6 months ago
Roberto Ierusalimschy	9d985db7bb	New year (2024)	6 months ago
Roberto Ierusalimschy	0897c0a428	'getmode' renamed to 'getMode' The name 'getmode' conficts with a function from BSD, defined in <unistd.h>. Although 'lbaselib.c' cannot include that header, 'onelua.c' can.	7 months ago
Roberto Ierusalimschy	5edacafcfa	Yet another representation for arrays This "linear" representation (see ltable.h for details) has worse locality than cells, but the simpler access code seems to compensate that.	7 months ago
Roberto Ierusalimschy	3507c3380f	Small simplification in 'findloader' Instead of allways adding a prefix for the next message, and then removing it if there is no message, add the prefix after each message.	7 months ago
Roberto Ierusalimschy	88a50ffa71	Fixed dangling 'StkId' in 'luaV_finishget' Bug introduced in `05932567`.	7 months ago
Roberto Ierusalimschy	86a8e74824	Details	7 months ago
Roberto Ierusalimschy	9fa63a6268	Some 'unsigned int' changed to 'unsigned' 'unsigned int' is too long sometimes. (We already write 'long' instead of 'long int'...)	8 months ago
Roberto Ierusalimschy	0593256707	'luaH_get' functions return tag of the result Undoing previous commit. Returning TValue increases code size without any visible gains. Returning the tag is a little simpler than returning a special code (HOK/HNOTFOUND) and the tag is useful by itself in some cases.	8 months ago
Roberto Ierusalimschy	ce6f5502c9	'luaH_get' functions return 'TValue' Instead of receiving a parameter telling them where to put the result of the query, these functions return the TValue directly. (That is, they return a structure.)	8 months ago
Roberto Ierusalimschy	ba71060381	Removed "bulk operations" Negligible performance gains don't justify extra complexity.	8 months ago
