Roberto Ierusalimschy 72d82a296c revamping the incremental collector
Some simplifications (not counting bytes, couting only slots visited;
no more 'gcfinnum'); more GC parameters; using vararg in 'lua_gc' to
set parameters in different GC modes
2017-05-26 16:14:29 -03:00
Roberto Ierusalimschy 2376eb6347 barrier for prototype's cache (with new gray list 'protogray' to keep
prototypes to have their caches visited again) + constant 'MAXMISS'
2017-05-04 10:32:01 -03:00
Roberto Ierusalimschy 8634b2a011 added 'cachemiss' field to prototype to avoid wasting time checking
hits that fail too often

Roberto Ierusalimschy f399e6705f ensures that "collectgarbage'step'" in generational mode does a
minor collection

Roberto Ierusalimschy 69371c4b84 'KGC_NORMAL' -> 'KGC_INC' + emergency GC signalled by flag (instead
of mode)

Roberto Ierusalimschy 0c8a7e071b 'mainthread' lives in 'allgc' list, like everybody else 2017-04-11 16:00:27 -03:00
Roberto Ierusalimschy a3d36fe283 Upvalues collected like everything else (with mark-sweep) instead
of reference count (simpler and better for generational mode)

Roberto Ierusalimschy 7b1fba69b7 using 'lastfree == NULL' to signal that table is using the dummy
node for its hash part + new macro 'allocsizenode'
2016-11-07 10:38:35 -02:00
Roberto Ierusalimschy 138d00176c new flag in 'CallInfo.callstatus' to tell whether function is running
as a finalizer
2016-10-19 10:31:42 -02:00
Roberto Ierusalimschy 8d4feb504f do not try to ensure that 'sweepgc' points to a live object
when entering sweep phase ('entersweep'); that may be too
expensive to be done still inside the atomic step. Walking
one single object more often than not will work.

Roberto Ierusalimschy 03412af06e detail (removed fixed argument to function 'callallpendingfinalizers') 2015-12-10 16:12:30 -02:00

argument

Roberto Ierusalimschy cd73f3ccc5 now that we have a counter for CallInfos, use it for a more
accurate value for the memory used by a thread
2015-11-02 14:19:29 -02:00
Roberto Ierusalimschy 41964648ee long strings are created directly in final position when possible
(instead of using an auxiliar buffer to first create the string
and then allocate the final string and copy result there)

Roberto Ierusalimschy 2b61360d82 avoid overflows (detected with 'clang -ftrapv') 2015-07-13 10:30:03 -03:00
Roberto Ierusalimschy b436ed58a3 'clearapihash' -> 'luaS_clearcache' and moved to 'lstring.c' (which
keeps all code related to this cache)

Roberto Ierusalimschy 3a15c7ce43 size for array part of a table ('sizearray') changed from 'int' to
'unsigned int', which allows twice as many elements in the array part

Roberto Ierusalimschy 3c6d0aaa7d 'iswhite' and related macros now can work directly on any object
(no need to convert to 'GCObject')
2014-07-19 12:14:46 -03:00
Roberto Ierusalimschy e43612aaf6 put the restriction that 'luaC_barrierback' works only on tables
in its prototype
2014-07-19 12:09:37 -03:00
Roberto Ierusalimschy 2898e2fd12 removed useless assertion (gcstate != GCSpause already implied by
other assertions) and wrong assertion (setmetatable uses this barrier
for tables too)
2014-07-19 11:44:19 -03:00
Roberto Ierusalimschy bb12903120 type 'Udata' refers directly to structure inside the union (union

2014-07-18 11:46:47 -03:00
Roberto Ierusalimschy ca41b43f53 type 'TString' refers directly to the structure inside the union
