Roberto Ierusalimschy	f874d37fa2	Small change in barrier macros Reuse macros for objects when defining the macros for values.	2 years ago
Roberto Ierusalimschy	5d8b5b9290	Changed signal of GC debt Positive debts seems more natural then negative ones.	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	d324a0ccf9	Simpler control for major collections	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	9ede317c70	Threads are created like other objects Using a version of 'luaC_newobj' that allows offsets (extra space before the object itself).	2 years ago
Roberto Ierusalimschy	597a53bbc6	Bug: finalizer calling exit can corrupt finalization order 'os.exit' can call lua_close again, separating new finalizers created after all previous finalizers were already separated.	3 years ago
Roberto Ierusalimschy	0bfc572e51	Bug: GC is not reentrant As the GC is not reentrant, finalizers should not be able to invoke it.	3 years ago
Roberto Ierusalimschy	f849885a4b	Small changes in macros that change GC colors - Macro 'gray2black' was renamed 'nw2black' (Non-White to black), as it was already being used on objects that could be already black. - Macros 'white2gray' and 'black2gray' were unified in 'set2gray'; no reason to have two macros when one will do and, again, 'black2gray' was already being used on objects that could be already gray. Moreover, macros 'maskcolors' and 'maskgcbits' were negated to have ones in the described bits, instead of zeros. (This naming seems more intuitive.)	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	7c3cb71fa4	Free bit 7 of GC 'marked' field Tables were using this bit to indicate their array sizes were real ('isrealasize'), but this bit can be useful for tests. Instead, they can use bit 7 of their 'flag' field for that purpose. (There are only six fast-access metamethods.) This 'flag' field only exists in tables, so this use does not affect other types.	4 years ago
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	992b6d2712	no more 'TESTGRAYBIT' (to free this bit for real uses)	7 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	a3d36fe283	Upvalues collected like everything else (with mark-sweep) instead of reference count (simpler and better for generational mode)	8 years ago
