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
Roberto Ierusalimschy	3823fc6c81	Added "bulk operations" to arrays A few operations on arrays can be performed "in bulk", treating all tags of a cell as a simple (or a few) word(s).	8 months ago
Roberto Ierusalimschy	52aa2b5d24	Details - 'unsigned int' -> 'unsigned' - Some explicit casts to avoid warnings - Test avoids printing the value of 'fail' (which may not be nil)	8 months ago
Roberto Ierusalimschy	cc2b66c856	Removed type 'varint_t' size_t should be big enough to count the number of strings in a dump. (And, by definition, it is big enough to count the length of each string.)	8 months ago
Roberto Ierusalimschy	65b07dd53d	API asserts for illegal pops of to-be-closed variables	8 months ago
Roberto Ierusalimschy	7237eb3f1c	Fixed warnings from different compilers	9 months ago
Roberto Ierusalimschy	165389b27b	New interface to function 'luaL_openselectedlibs' Instead of preloading all non-loaded libraries, there is another mask to select which libraries to preload.	9 months ago
Roberto Ierusalimschy	c8121ce34b	Revising code for Varint encoding in dumps - Usign lua_Unsigned to count strings. - Varint uses a type large enough both for size_t and lua_Unsigned. - Most-Significant Bit 0 means last byte, to conform to common usage. - (unrelated) Change in macro 'getaddr' so that multiplication is by constants.	9 months ago
Roberto Ierusalimschy	7360f8d0fd	Removed deprecated function 'setcstacklimit'	9 months ago
Roberto Ierusalimschy	6063c47031	Field 'lastfree' changed (back) to 'Node *' Due to allignment, it is already using the space of a pointer, and a pointer generates slightly simpler code.	9 months ago
Roberto Ierusalimschy	0c9bec0d38	Better handling of size limit when resizing a table Avoid silent conversions from int to unsigned int when calling 'luaH_resize'; avoid silent conversions from lua_Integer to int in 'table.create'; MAXASIZE corrected for the new implementation of arrays; 'luaH_resize' checks explicitly whether new size respects MAXASIZE. (Even constructors were bypassing that check.)	9 months ago
Roberto Ierusalimschy	c31d6774ac	Details	9 months ago
Roberto Ierusalimschy	108e0bdc84	Merge branch 'master' into nextversion	10 months ago
Roberto Ierusalimschy	b34a97a4af	Small optimization in 'luaH_psetint' It is quite common to write to empty but existing cells in the array part of a table, so 'luaH_psetint' checks for the common case that the table doesn't have a newindex metamethod to complete the write.	10 months ago
Roberto Ierusalimschy	3e9dbe143d	New function 'table.create' Creates a table preallocating memory. (It just exports to Lua the API function 'lua_createtable'.)	10 months ago
Roberto Ierusalimschy	4a8e480864	New mechanism to query GC parameters	10 months ago
Roberto Ierusalimschy	17e0c29d9b	Clear interface between references and predefines The reference system has a defined way to add initial values to the table where it operates.	10 months ago
Roberto Ierusalimschy	8eb0abc9db	Removed uses of LUA_NUMTAGS That constant was already deprecated (see commit `6aabf4b15e`).	10 months ago
Roberto Ierusalimschy	d862da6d04	Optimizations for 'lua_rawgeti' and 'lua_rawseti' 'lua_rawgeti' now uses "fast track"; 'lua_rawseti' still calls 'luaH_setint', but the latter was recoded to avoid extra overhead when writing to the array part after 'alimit'.	10 months ago
Roberto Ierusalimschy	e288c5a918	Bug: Yielding in a hook stops in the wrong instruction Yielding in a hook must decrease the program counter, because it already counted an instruction that, in the end, was not executed. However, that decrement should be done only when about to restart the thread. Otherwise, inspecting the thread with the debug library shows it one instruction behind of where it really is.	10 months ago
Roberto Ierusalimschy	7827c40c49	A few more tweaks in the garbage collector	10 months ago
Roberto Ierusalimschy	e7af9cdf0b	Fixed buffers reuse absolute line information	11 months ago
Roberto Ierusalimschy	12b6f610b0	Several tweaks in the garbage collector - back with step size in collectgarbage("step") - adjustments in defaults for some GC parameters - adjustments in 'luaO_codeparam'	11 months ago
Roberto Ierusalimschy	e81f586001	Removed compatibility option LUA_COMPAT_GCPARAMS The meaning of different GC parameters changed, so there is point in supporting old values for them. The new code simply ignores the parameters when changing the GC mode, so the incompatibility is small.	11 months ago
Roberto Ierusalimschy	e2cc179454	New option "setparms" for 'collectgarbage' The generational mode also uses the parameters for the incremental mode in its major collections, so it should be easy to change those parameters without having to change the GC mode.	11 months ago
Roberto Ierusalimschy	5853c37a83	Bug: Buffer overflow in string concatenation Even if the string fits in size_t, the whole size of the TString object can overflow when we add the header.	11 months ago
Roberto Ierusalimschy	ad0ea7813b	GC parameters encoded as floating-point bytes This encoding brings more precision and a larger range for these parameters.	11 months ago
Roberto Ierusalimschy	666e95a66d	Option 0 for step multiplier makes GC non-incremental	11 months ago
Roberto Ierusalimschy	4eda1acafa	Cleaner protocol between 'lua_dump' and writer function 'lua_dump' signals to the writer function the end of a dump, so that is has more freedom when using the stack.	11 months ago
Roberto Ierusalimschy	ad73b33224	Check minor->major made at the end of a minor cycle It does not make sense to wait for another cycle to decide when much of the information about creation of old objects is already available.	11 months ago
