Roberto Ierusalimschy 0567221848 udata in 'tobefnz' list be have old bit on (it will be cleared 
when udata is moved to 'allgc' list)
 2010-05-10 15:24:36 -03:00
Roberto Ierusalimschy 1c1a98e872 corrected some places where an old object could end up in front 
of a new one + minimal documentation about this problem
 2010-05-10 15:23:45 -03:00
Roberto Ierusalimschy c006f085d9 new macro 'resetoldbit' 2010-05-10 13:46:49 -03:00
Roberto Ierusalimschy a48e330f37 macros 'lua_number2int' and 'lua_number2uint' for Visual Studio 
corrected and tested
 2010-05-10 13:38:58 -03:00
Roberto Ierusalimschy dcc070683c avoid reserving LUA_RIDX_LAST slots in any table used by reference 
system. Store free list in a field indexed by a unique name,
instead of using a numerical index.
 2010-05-10 12:25:02 -03:00
Roberto Ierusalimschy 2d81cfa4e1 corrected definition of 'lua_register' (there is no LUA_ENVIRONINDEX 
anymore)
 2010-05-10 10:50:20 -03:00
Roberto Ierusalimschy 0bccf03d7e slightly better definition for 'changenvalue' 2010-05-07 15:44:46 -03:00

Roberto Ierusalimschy 32c1764b5d slightly better definition for 'isgray' 2010-05-07 15:43:51 -03:00
Roberto Ierusalimschy de97177744 avoid 'else assert' (which may result in an empty else) 2010-05-07 15:43:24 -03:00
Roberto Ierusalimschy fa2ddb070a details (to avoid too long strings in assertions) 2010-05-07 15:23:17 -03:00
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 8e1bdda66a stupid bug when calling 'luaC_changemode' (in function lua_gc) 2010-05-07 15:10:01 -03:00
Roberto Ierusalimschy 9c1347e647 more tests in 'lua_checkmemory' + more information in function 
'gccolor'
 2010-05-07 15:09:23 -03:00
Roberto Ierusalimschy b373a40133 new macro 'isgenerational' + new macro 'isold' + better deffinition 
for 'isdead', compatible with the code used by 'sweeplist'
 2010-05-07 15:08:05 -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 a4f20e3c8b comments 2010-05-06 15:17:22 -03:00
Roberto Ierusalimschy 8c583c61a3 more tests in 'lua_checkmemory' 2010-05-06 15:16:57 -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
Roberto Ierusalimschy d77898597e new function 'luaC_changemode' 2010-05-05 15:53:41 -03:00

Roberto Ierusalimschy fde866e303 details (comments) 2010-05-04 14:25:19 -03:00
Roberto Ierusalimschy 2d7a81a204 missing parentheses in declaration 2010-05-04 14:21:08 -03:00
Roberto Ierusalimschy 658ea8752b no need to handle '\0' differently from other control chars in 
format '%q'
 2010-05-04 14:20:33 -03:00
Roberto Ierusalimschy aa73403ba4 no need of a KGC_FORCED collection kind; it has the same behavior of 
a normal collection
 2010-05-03 14:39:48 -03:00
Roberto Ierusalimschy 0c27de2e7b no more 'finalize' phase in GC; finalizers are called along the 
entire cycle
 2010-05-03 14:33:39 -03:00
Roberto Ierusalimschy d25f7f9d78 items in 'tobefnz' are kept black (as before recent change) and changed

invariant).
 2010-05-03 08:55:40 -03:00
Roberto Ierusalimschy 85555646e3 invariant must be kept in atomic 'phase' too 2010-05-03 08:24:30 -03:00

Roberto Ierusalimschy 9a9fe42deb wrong comment 2010-04-30 15:17:24 -03:00
Roberto Ierusalimschy 0062db1e06 default PAUSE should be 200 (differences may be corrected in 
internal multiplers)
+ check for unbilt stack equal the one used by lgc.c
 2010-04-30 11:22:23 -03:00
Roberto Ierusalimschy 23001d8607 nasty GC bug: upvalue must be turned white when not keeping invariant, 
but barrier was not being called when uv->v were already white.
 2010-04-29 18:43:36 -03:00
Roberto Ierusalimschy 5d79c6684b removed commented-out debugging code 2010-04-29 18:42:33 -03:00

Roberto Ierusalimschy 3eb1788bb4 new way to control GC speed (keeping a 'debt' counter) 2010-04-29 14:31:31 -03:00
Roberto Ierusalimschy 00114a95b2 lots of new comments + small changes in loop controls + other small 
"janitor work"
 2010-04-26 14:58:00 -03:00
Roberto Ierusalimschy 4aaf0ef75c "to-be-finalized" objects marked and sweeped like all other objects 2010-04-20 17:15:30 -03:00
Roberto Ierusalimschy ed720d09f3 upvalue barriers for Lua functions must act on the upvalue itself, 
not on its closure

Roberto Ierusalimschy 9d28e2b3e5 bug with io.read(op, "*n") 2010-04-19 15:04:58 -03:00
Roberto Ierusalimschy 49ca1f7083 allows thread switches (when/if there are thread switches) in the same 
places that finalizers can run (so they should be safe...)
 2010-04-19 14:58:46 -03:00
Roberto Ierusalimschy 4db6f20770 ensure that 'luai_userstatethread' is always called (even if 
'stack_init' throws a memory error)
