Roberto Ierusalimschy	b14609032c	Avoid the creation of too many strings in 'package' Both when setting a path and searching for a file ('searchpath'), this commit reduces the number of intermediate strings created in Lua. (For setting a path the change is not relevant, because this is done only twice when loading the module. Anyway, it is a nice example of how to use auxlib buffers to manipulate strings in the C API.)	6 years ago
Roberto Ierusalimschy	2c32bff609	After a "bad collections", avoid switching back back to generational After a major bad collection (one that collects too few objects), next collection will be major again. In that case, avoid switching back to generational mode (as it will have to switch again to incremental to do next major collection).	6 years ago
Roberto Ierusalimschy	e8c779736f	Removed internal cache for closures The mechanism of "caching the last closure created for a prototype to try to reuse it the next time a closure for that prototype is created" was removed. There are several reasons: - It is hard to find a natural example where this cache has a measurable impact on performance. - Programmers already perceive closure creation as something slow, so they tend to avoid it inside hot paths. (Any case where the cache could reuse a closure can be rewritten predefining the closure in some variable and using that variable.) - The implementation was somewhat complex, due to a bad interaction with the generational collector. (Typically, new closures are new, while prototypes are old. So, the cache breaks the invariant that old objects should not point to new ones.)	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	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	a3d36fe283	Upvalues collected like everything else (with mark-sweep) instead of reference count (simpler and better for generational mode)	8 years ago

Roberto Ierusalimschy	d8aa8dd97e	objects in list 'tobefnz' have a GC life-cycle like all others (specifically they are cleaned during sweep phase)	11 years ago
Roberto Ierusalimschy	1150873447	'luaC_newobj' does not handle special cases; only special case now is threads, which do not use 'luaC_newobj' anymore.	11 years ago
Roberto Ierusalimschy	aeff4f79fa	local collection now calls finalizers	11 years ago
Roberto Ierusalimschy	1bf4faec64	new GC state to sweep 'localgc' list + small changes in sweep control	11 years ago
Roberto Ierusalimschy	26629d0af1	details (a few casts moved from macro invocation to macro definition)	11 years ago
Roberto Ierusalimschy	90972ff136	LOCALBLACK changed to LOCALMARK and used also to control whether object is in 'localgc' list + luaC_newobj by default puts object in 'localgc' list	11 years ago
Roberto Ierusalimschy	af35c7f398	upvalues collected by reference count	11 years ago

Roberto Ierusalimschy	439d74e29f	added 'local' bit (true => object is only refered by local variables)	11 years ago
Roberto Ierusalimschy	3679d33b02	barrier conditions rewritten to test first 'isblack' and then 'iswhite' (during a pause all objects are white, so 'isblack' fails much more often than 'iswhite')	11 years ago
Roberto Ierusalimschy	677d90165f	no more generational collection !!!	11 years ago
Roberto Ierusalimschy	ae1d318822	small bug: generational mode is always in 'propagate' mode only outside the collector: during collection of course it must go to other modes.	12 years ago
