Roberto Ierusalimschy 063d4e4543 Lua 5.3.5 ported to git 
This is the first commit for the branch Lua 5.3. All source files
were copied from the official distribution of 5.3.5 in the Lua site.
The test files are the same of 5.3.4. The manual came from the
previous RCS repository, revision 1.167.1.2.

 2014-02-18 10:46:26 -03:00
Roberto Ierusalimschy 1cce3e6842 change in the way 'collectgarbage("step", size)' interprets 'size'

Kbytes)

Roberto Ierusalimschy 4eeb1831be new names and better order for GC states (sweep first lists that 
can have dead objects)
 2013-09-11 11:47:08 -03:00
Roberto Ierusalimschy dd373a8f66 threads are kept in a separated GC list, linked after the main thread 2013-09-11 11:09:55 -03:00
Roberto Ierusalimschy d8aa8dd97e objects in list 'tobefnz' have a GC life-cycle like all others 
(specifically they are cleaned during sweep phase)
 2013-09-11 09:47:48 -03:00
Roberto Ierusalimschy 1150873447 'luaC_newobj' does not handle special cases; only special case 
now is threads, which do not use 'luaC_newobj' anymore.
 2013-09-11 09:26:14 -03:00
Roberto Ierusalimschy aeff4f79fa local collection now calls finalizers 2013-09-03 12:37:10 -03:00

Roberto Ierusalimschy 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

list
 2013-08-27 17:04:00 -03:00
Roberto Ierusalimschy af35c7f398 upvalues collected by reference count 2013-08-27 15:53:35 -03:00
Roberto Ierusalimschy 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
Roberto Ierusalimschy 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

Roberto Ierusalimschy 3679d33b02 barrier conditions rewritten to test first 'isblack' and then 'iswhite'

often than 'iswhite')
 2013-08-13 14:36:44 -03:00
Roberto Ierusalimschy 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.

 2012-05-21 10:18:10 -03:00
Roberto Ierusalimschy 31829ad177 test for whether collector is running moved from function to

state if an error happens in a step
 2010-12-29 16:00:23 -02:00
