3c6d0aaa7d 'iswhite' and related macros now can work directly on any object
(no need to convert to 'GCObject')

e43612aaf6 put the restriction that 'luaC_barrierback' works only on tables

3f78de256e no need to keep threads in a different GC list, now that there is the
'twups' list
2014-02-18 10:46:26 -03:00

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

ba3586cc90 keep a single list of objects to be finalized (with local and non-local
objects), to ensure finalization order

4eeb1831be new names and better order for GC states (sweep first lists that

dd373a8f66 threads are kept in a separated GC list, linked after the main thread 2013-09-11 11:09:55 -03:00

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.

26629d0af1 details (a few casts moved from macro invocation to macro definition) 2013-08-29 10:49:57 -03:00
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

af35c7f398 upvalues collected by reference count 2013-08-27 15:53:35 -03:00

50955e27f5 C functions and strings now go to the local list; first version
of the local collector
2013-08-23 10:34:54 -03:00

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
Roberto Ierusalimschy
ae800656c9 change in string table: string table is now independent of GC lists; all
strings live in 'normal' GC lists
2013-08-21 16:21:16 -03:00

8f6b80aa1d GC bits SEPARATED and FINALIZEDBIT mixed in FINALIZEDBIT (with simpler
control)

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
Roberto Ierusalimschy
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')

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

e4f609d0ee collector in generational mode must be in 'propagate' state when

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

868ff40339 full collection does not restart collector + avoid changing GC
state if an error happens in a step
