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

a3d36fe283 Upvalues collected like everything else (with mark-sweep) instead
of reference count (simpler and better for generational mode)

1cce3e6842 change in the way 'collectgarbage("step", size)' interprets 'size'
(mimicking the way the GC itself behaves when Lua allocates 'size'
Kbytes)

1150873447 'luaC_newobj' does not handle special cases; only special case
now is threads, which do not use 'luaC_newobj' anymore.

90972ff136 LOCALBLACK changed to LOCALMARK and used also to control whether object
is in 'localgc' list + luaC_newobj by default puts object in 'localgc'

of the local collector

0df6635711 "fixed" objects kept in a separated list (instead of being kept in
'allgc' list with a bit marking them)
2013-08-21 17:09:51 -03:00

ae800656c9 change in string table: string table is now independent of GC lists; all
strings live in 'normal' GC lists

9eff921f8f "barrier" for link prototype->cache changed to be consistent with

439d74e29f added 'local' bit (true => object is only refered by local variables) 2013-08-16 15:55:49 -03:00

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')

677d90165f no more generational collection !!! 2013-08-05 13:58:28 -03:00

ae1d318822 small bug: generational mode is always in 'propagate' mode only
outside the collector: during collection of course it must go to
other modes.

398811a313 simpler macro 'luaC_condGC' + better 'step' in 'lua_gc' +
micro bug in 'luaC_checkfinalizer' (current sweep object could be
removed from 'allgc' list)
2012-05-21 10:18:10 -03:00

31829ad177 test for whether collector is running moved from function to
