Author	SHA1	Message	Date
Roberto Ierusalimschy	ccae0f5aad	Comments about OLD0/OLD1 ages Improved the comments in file 'lgc.c' explaining the roles of "ages" OLD0 and OLD1 in the generacional collector.	6 years ago
Roberto Ierusalimschy	2e297d6ab3	Fixed bug in generational collection of userdata During generational collection, a userdatum must become gray and go to a gray list after being traversed (like tables), so that 'correctgraylist' can handle it to its next stage. This commit also added minimum tests for the generational collector, including one that would detect this bug.	6 years ago
Roberto Ierusalimschy	626cf0581b	Generational mode may wait longer after a major collection When Lua is building large long-duration structures, frequent small minor collections just waste time. Trying to avoid this, the collector will do a larger pause after a major collection when it does not collect enough garbage (which is a hint that memory is being used for long-lasting objects).	6 years ago
Roberto Ierusalimschy	6e600695f8	field 'sizearray' in struct 'Table' changed to 'alimit', which can be used as a hint for '#t'	6 years ago
Roberto Ierusalimschy	0c7738240e	FALLTHROUGH comment must be last "statement" (so it does not work when inside a block)	7 years ago
Roberto Ierusalimschy	2952bc5fc9	special compact representation for userdata with no user values (a common case)	7 years ago
Roberto Ierusalimschy	4a7fe61806	in 'clearbykeys', clear keys of just-removed entries too	7 years ago
Roberto Ierusalimschy	9243c414d9	first version of empty entries in tables (so that, in the future, tables can contain regular nil entries)	7 years ago
Roberto Ierusalimschy	477ca2fe8c	some reorganization in 'lobject.h' (just moving stuff around)	7 years ago
Roberto Ierusalimschy	ca6fe7449a	userdata can have multiple user values	7 years ago
Roberto Ierusalimschy	1afd5a152d	more generic way to handle 'gclist'	7 years ago
Roberto Ierusalimschy	daff7c3b4d	small corrections in generational mode (cannot call finalizers in emergency collections + should set everything before calling finalizers)	7 years ago
Roberto Ierusalimschy	e2b15aa21d	janitor work on casts	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	e663a24ab0	more freedom in handling memory-allocation errors (not all allocations automatically raise an error), which allows fixing a bug when resizing a table.	7 years ago
Roberto Ierusalimschy	421e459684	'luaS_resize' can raise memory errors	7 years ago
Roberto Ierusalimschy	ac78b914b6	warnings from Visual Studio /W3	7 years ago
Roberto Ierusalimschy	599f1742c6	detail (typo in comments)	7 years ago
Roberto Ierusalimschy	ad0704e40c	back to 'CallInfo' (no gains with its removal)	7 years ago
Roberto Ierusalimschy	54eb35a8aa	more fields moved out of 'CallInfo'	7 years ago
Roberto Ierusalimschy	de9128d09d	do not mess up the debt when the collector is not running	7 years ago
Roberto Ierusalimschy	1d8920dd7f	some cleaning in GC parameters	7 years ago
Roberto Ierusalimschy	029d269f4d	bug: dead keys with nil values can stay in weak tables	7 years ago
Roberto Ierusalimschy	f96497397a	new type 'StackValue' for stack elements (we may want to put extra info there in the future)	7 years ago
Roberto Ierusalimschy	73ec04fcf3	no more 'DEADKEY'. Table traversals do not need to consider dead keys; if the key is dead, it cannot be given to 'next'. Instead, we now use a 'table' tag without the collectable bit, which makes it a unique tag good enough to reserve space.	8 years ago
Roberto Ierusalimschy	b6f87491af	in hash nodes, keys are stored in separate pieces to avoid wasting space with alignments	8 years ago
Roberto Ierusalimschy	4bc33d64de	avoid overflows in computation of step size	8 years ago
Roberto Ierusalimschy	72d82a296c	revamping the incremental collector Some simplifications (not counting bytes, couting only slots visited; no more 'gcfinnum'); more GC parameters; using vararg in 'lua_gc' to set parameters in different GC modes	8 years ago
Roberto Ierusalimschy	2376eb6347	barrier for prototype's cache (with new gray list 'protogray' to keep prototypes to have their caches visited again) + constant 'MAXMISS'	8 years ago
Roberto Ierusalimschy	8634b2a011	added 'cachemiss' field to prototype to avoid wasting time checking hits that fail too often	8 years ago
Roberto Ierusalimschy	f399e6705f	ensures that "collectgarbage'step'" in generational mode does a minor collection	8 years ago
Roberto Ierusalimschy	69371c4b84	'KGC_NORMAL' -> 'KGC_INC' + emergency GC signalled by flag (instead of mode)	8 years ago
Roberto Ierusalimschy	c354211744	small bug in generational control	8 years ago
Roberto Ierusalimschy	c7bdc0e0e8	first version of control for the generational collector	8 years ago
Roberto Ierusalimschy	16001acb15	small corrections + removal of debugging functions 'count' and 'printgray'.	8 years ago
Roberto Ierusalimschy	0c8a7e071b	'mainthread' lives in 'allgc' list, like everybody else	8 years ago
Roberto Ierusalimschy	a3d36fe283	Upvalues collected like everything else (with mark-sweep) instead of reference count (simpler and better for generational mode)	8 years ago
Roberto Ierusalimschy	9569ad6b0d	Comments for generational collector	8 years ago
Roberto Ierusalimschy	2331e1beec	small changes in 'luaC_upvalbarrier'	8 years ago
Roberto Ierusalimschy	e4287da3a6	generational collector (still not complete)	8 years ago
Roberto Ierusalimschy	f5f3df3bd1	generational collection: new attempt (still incomplete)	8 years ago
Roberto Ierusalimschy	2a235312f0	detail (removing spaces at end of lines)	8 years ago
Roberto Ierusalimschy	7b1fba69b7	using 'lastfree == NULL' to signal that table is using the dummy node for its hash part + new macro 'allocsizenode'	8 years ago
Roberto Ierusalimschy	138d00176c	new flag in 'CallInfo.callstatus' to tell whether function is running as a finalizer	8 years ago
Roberto Ierusalimschy	8d4feb504f	do not try to ensure that 'sweepgc' points to a live object when entering sweep phase ('entersweep'); that may be too expensive to be done still inside the atomic step. Walking one single object more often than not will work.	9 years ago
Roberto Ierusalimschy	03412af06e	detail (removed fixed argument to function 'callallpendingfinalizers')	9 years ago
Roberto Ierusalimschy	7485512384	added comment and assert about dead keys	9 years ago
Roberto Ierusalimschy	ff1289a361	in 'luaD_call', use two functions instead of one with fixed boolean argument	9 years ago
Roberto Ierusalimschy	cd73f3ccc5	now that we have a counter for CallInfos, use it for a more accurate value for the memory used by a thread	9 years ago
