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

2a66b34f72 revamp of the GC pace control; more like 5.1: any X Kbytes allocated 
makes the GC handle f(X) Kbytes of objects

Roberto Ierusalimschy
0fac33da9e bug: incremental sweep was not cleaning old bits (as it stopped in the 
first old object) + bug: moving udata to 'udgc' list might put old
object in front a new one + some new macros + generational mode may
be in 'pause' state (it just skips 'markroot')
 2010-05-07 15:19:36 -03:00
Roberto Ierusalimschy
25951e0ea5 some cleaning in 'sweeplist' (threads do not need to be traversed 
if they are going to be collected + use of bit masks to unify
differences in generational and incremental modes)
 2010-05-06 15:18:07 -03:00
Roberto Ierusalimschy
d2ea5b00b7 new function 'luaC_changemode' + 
bug: objects entering the 'allgc' list must have their OLDBIT cleared
(upvalues being cleared) + bug: in 'checkSizes', KGC_EMERGENCY is
stored in 'gckind' field, not in 'gcstate' + current white changes when
entering sweep phase (so there are dead objects only in that phase)
 2010-05-05 15:58:36 -03:00

d25f7f9d78 items in 'tobefnz' are kept black (as before recent change) and changed

Roberto Ierusalimschy
4433dbb5f5 userdata with finalizers are kept in a separated list ('udgc'), instead 
of at the end of 'rootgc' (which was renamed to 'allgc', as it is not
"root" in the usual meaning for collectors)
