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

that phases with small lists return 0 at the first call to 'sweepstep'

d8aa8dd97e objects in list 'tobefnz' have a GC life-cycle like all others
(specifically they are cleaned during sweep phase)

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

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'

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
GC behavior (link is cleared to preserve invariant)
2013-08-19 11:18:43 -03:00

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

c37b7b3cca bug: garbage collector can trigger too many times in recursive loops,
because it was not computing the size of CallInfo structures in threads

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

pace control (for the atomic part)

b36b4b521f try to avoid sweeping new objects created with new white (and
therefore not collectable in the current cycle)
