8f6b80aa1d GC bits SEPARATED and FINALIZEDBIT mixed in FINALIZEDBIT (with simpler 
control)
 2013-08-20 14:46:34 -03:00
Roberto Ierusalimschy
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')

78b941039d change to allow collector to stop when it goes to the atomic phase 
(just for debugging)
 2013-08-07 12:39:09 -03:00

623e388bb4 double-linked list of all upvalues elliminated and changed to a 
traversal of all non-marked threads

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

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.
 2012-09-11 09:53:08 -03:00

e4f609d0ee collector in generational mode must be in 'propagate' state when 
not running a collection

4fc15bbfb7 major collections in generational mode are triggered by comparison with 
the memory estimate from last major collection

c510d94549 includes counts from 'sweeptolive' in cost of atomic step 2012-05-31 18:28:59 -03:00
Roberto Ierusalimschy
ab2c3d5cde small bug in error handling of finalizers (cannot call lua_tostring 
inside the core) + small bug in luaC_checkfinalizer (when avoiding
remove object being sweeped from sweep list) + small changes in GC
pace control (for the atomic part)
 2012-05-31 17:26:14 -03:00

6fcdfc6d4f bug: object being moved to 'finobj' list might not be sweeped by 
the collector
 2012-05-30 13:01:10 -03:00

6efffb9acd only count in 'atomic' objects marked for the first time 2012-05-29 14:52:17 -03:00

086da10dac merge of fields 'lastmajormem' (used in gen. mode) and 'estimate' 
(used in inc. mode)

b36b4b521f try to avoid sweeping new objects created with new white (and 
therefore not collectable in the current cycle)
 2012-05-22 14:32:25 -03:00

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

2a66b34f72 revamp of the GC pace control; more like 5.1: any X Kbytes allocated 
makes the GC handle f(X) Kbytes of objects
 2012-05-20 17:36:44 -03:00

31829ad177 test for whether collector is running moved from function to 
macro 'luaC_condGC'.

3cadc37f47 no more 'Proto' objects on the stack. Protos are anchored on outer 
Protos or on a Closure, which must be created before the Proto.

fd22ccd6d0 object tag keeps variant bits too -> no need for 'isC' field in 
Closures + more strick typing for closure variants

bc90cf4b83 retraverse all gray lists together to avoid traversing some weak 
tables twice (as they may change lists when traversed)

87912786af dead objects are not collectable. 2011-09-24 18:12:01 -03:00

95ed6c1127 better(?) scheme for cleaning weak tables; all ressurected objects 
are removed from weak values before finalization
 2011-09-24 18:00:40 -03:00
Roberto Ierusalimschy
45c346645c avoid clearing ephemeron tables that have nothing to be cleaned 
(no white elements)
 2011-09-19 14:03:38 -03:00

74b0bb3a45 macro 'checkconsistency' moved to this file, as it is used only 
here

868ff40339 full collection does not restart collector + avoid changing GC 
state if an error happens in a step
 2010-12-29 16:00:23 -02:00
Roberto Ierusalimschy
551b076f1c change in the relationship between totalbytes and GCdebt - luaM_realloc_ 
is too critical to update two counters
 2010-12-20 17:40:07 -02:00
