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	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	789e7acdea	Major collections done incrementally Major collections do not need to "stop the world". Still pending: criteria for shifts minor-major, shifts generational-incremental.	11 months ago
Roberto Ierusalimschy	63d68bd657	Comments detailing the ages for generational GC Plus other comments and small details.	11 months ago
Roberto Ierusalimschy	25cd3d377e	Buffer in 'luai_makeseed' measured in bytes In the (rare) cases when sizeof(void*) or sizeof(time_t) are not multiples of sizeof(int), we still can use all their bytes in the seed.	12 months ago
Roberto Ierusalimschy	024f9064f1	External strings Strings can use external buffers to store their contents.	1 year ago
Roberto Ierusalimschy	43c8e5bded	Full abstraction for representation of array values	1 year ago
Roberto Ierusalimschy	14e416355f	Added suport for Fixed Buffers A fixed buffer keeps a binary chunk "forever", so that the program does not need to copy some of its parts when loading it.	1 year ago
Roberto Ierusalimschy	6443185167	"Emergency" new version 5.4.6 'lua_resetthread' is back to its original signature, to avoid incompatibilities in the ABI between releases of the same version. New function 'lua_closethread' added with the "correct" signature.	2 years ago
Roberto Ierusalimschy	5a04f1851e	New function 'luaL_makeseed' This function unifies code from 'lua_newstate', 'math.randomseed', and 'table.sort' that tries to create a value with a minimum level of randomness.	2 years ago
Roberto Ierusalimschy	40565b4a08	Revamp of GC parameters More uniformity when handling GC parameters + avoid divisions by 100 when applying them.	2 years ago
Roberto Ierusalimschy	d738c8d18b	New function 'luaL_openselectedlibs' Makes it easier to start Lua with only some standard libraries.	2 years ago
Roberto Ierusalimschy	d324a0ccf9	Simpler control for major collections	2 years ago
Roberto Ierusalimschy	ec61be9a7e	'l_mem' renamed to 'l_obj' to count objects	2 years ago
Roberto Ierusalimschy	f356d5acdd	First version of GC counting objects for control Still needs to review generational mode.	2 years ago
Roberto Ierusalimschy	8047b2d03e	Tables have a 'lastfree' information only when needed Only tables with some minimum number of entries in their hash part have a 'lastfree' field, kept in a header before the node vector.	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	1e64c1391f	Bug: stack overflow with nesting of coroutine.close	2 years ago
Roberto Ierusalimschy	14d2803e55	Details Some cast operations rewritten to use respective macros.	2 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	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
Roberto Ierusalimschy	4e47f81188	New implementation for to-be-closed variables To-be-closed variables are linked in their own list, embedded into the stack elements. (Due to alignment, this information does not change the size of the stack elements in most architectures.) This new list does not produce garbage and avoids memory errors when creating tbc variables.	4 years ago
Roberto Ierusalimschy	cc1692515e	New API function 'lua_closeslot' Closing a to-be-closed variable with 'lua_settop' is too restrictive, as it erases all slots above the variable. Moreover, it adds side effects to 'lua_settop', which should be a fairly basic function.	4 years ago
Roberto Ierusalimschy	748d6d4e7a	Review of asserts in 'ltests.c' The module 'ltests.c' must work correctly with asserts off, too.	4 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	9a89fb1c9d	Hash always use all characters in a long string Hashes for long strings are computed only when they are used as keys in a table, not a too common case. And, in that case, it is to easy to force collisions changing only the characters which are not part of the hash.	4 years ago
Roberto Ierusalimschy	5aa36e894f	No more field 'lua_State.stacksize' The stack size is derived from 'stack_last', when needed. Moreover, the handling of stack sizes is more consistent, always excluding the extra space except when allocating/deallocating the array.	4 years ago
Roberto Ierusalimschy	f13dc59416	Better tests for gray lists Test uses an extra bit in 'marked' to mark all elements in gray lists and then check against elements colored gray.	4 years ago
Roberto Ierusalimschy	b9b554e0f6	Clearer handling of gray lists when entering generational mode When entering generational mode, all objects are old. So, the only objects that need to be in a gray list are threads, which can be assigned without barriers. Changes in anything else (e.g., weak tables) will trigger barriers that, if needed, will add the object to a gray list.	4 years ago
Roberto Ierusalimschy	b4c353434f	Details The fields 'old' and 'finobjold' were renamed 'old1' and 'finobjold1', respectively, to make clearer the main ages of their elements.	4 years ago
Roberto Ierusalimschy	8c7c9ea065	Function 'printobj' in 'ltests.c' made public It helps to have this function available for debugging.	4 years ago
Roberto Ierusalimschy	d39ea8b3ce	Make sure that main thread is non yieldable Main thread must be non yieldable even at "level 0" (bare API), outside the 'pcall' from 'lua.c'.	4 years ago
Roberto Ierusalimschy	bfcf06d91a	Avoid memory allocation in some functions from 'ltests.c' To allow their use in memory tests, some functions in 'ltests.c' should never allocate memory. To avoid this allocation, the library registers the strings used for status codes, and keeps the variable '_WARN' always defined (with false instead of nil).	4 years ago
Roberto Ierusalimschy	993c58fde3	In 'lua_checkmemory', userdata can be gray, too Since commit `ca6fe7449a`, userdata with uservalues can be gray and can belong to gray lists ('gclist').	4 years ago
Roberto Ierusalimschy	364e569945	Avoid calling 'fprintf' with NULL Avoid undefined behavior in calls like «fprintf("%s", NULL)». ('lua_writestringerror' is implemented as 'fprintf', and 'lua_tostring' can return NULL if object is not a string.)	4 years ago
Roberto Ierusalimschy	513559cc47	Fixed bug in 'string.format("%p")' The string "(null)" used for non-collectable values must be printed as a string, not as a pointer. (Bug introduced in commit `e0cbaa50fa`).	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	bd1b87c579	Comments (mosty typos)	5 years ago
Roberto Ierusalimschy	e592f94a64	Details (mostly comments)	5 years ago
Roberto Ierusalimschy	be78aeae4c	Default for warnings changed to "off" Warnings are mostly a tool to help developers (e.g., by showing hidden error messages); regular users usually don't need to see them.	5 years ago
Roberto Ierusalimschy	9405472565	Improvement in warn-mode '@store' (for testing) When using warn-mode '@store', from the test library, the tests ensure not only that the expected warnings were issued, but also that there was no extra warnings.	5 years ago
Roberto Ierusalimschy	ca13be9af7	Supressed errors in '__close' generate warnings	5 years ago
Roberto Ierusalimschy	a1d8eb2743	Added control messages to warnings Added the concept of control messages to the warning system, plus the implementation of the controls "@on"/"@off" to turn warnings on/off. Moreover, the warning system in the test library adds some other controls to ease the test of warnings.	5 years ago
Roberto Ierusalimschy	f645d31573	To-be-closed variables must be closed on initialization When initializing a to-be-closed variable, check whether it has a '__close' metamethod (or is a false value) and raise an error if if it hasn't. This produces more accurate error messages. (The check before closing still need to be done: in the C API, the value is not constant; and the object may lose its '__close' metamethod during the block.)	5 years ago
Roberto Ierusalimschy	dc07719b0d	Tag LUA_TUPVALTBC replaced by a flag It is simpler to signal a to-be-closed upvalue with a boolean flag, instead of using a different tag.	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	4487c28ced	A few more tests for table access in the API Added tests where the table being accessed is also the index or value in the operation.	5 years ago
Roberto Ierusalimschy	0b63d79b36	Details - 'luaL_setfuncs' avoids creating closures for placeholders. - Fixed some warnings about unused values in comma expressions. - Comments.	6 years ago
