Roberto Ierusalimschy 93fd67b793 no more 'CallInfo' structure 2017-11-04 10:57:02 -02:00
Roberto Ierusalimschy 472c560705 no more useful fields in CallInfo 2017-11-03 15:22:54 -02:00
Roberto Ierusalimschy 54eb35a8aa more fields moved out of 'CallInfo' 2017-11-03 10:12:30 -02:00
Roberto Ierusalimschy ba36180fd7 new API for 'lua_resume' + cleaning the uses of the 'extra' field in 
'CallInfo'
 2017-11-02 09:28:56 -02:00
Roberto Ierusalimschy c5482468fd baby steps to remove 'CallInfo': keeping 'L->func' correct 2017-10-31 15:54:35 -02:00
Roberto Ierusalimschy 6d998055c8 no more reference 'memerrmsg' + new reference to "n" 
(both can be retrieved by 'luaS_newliteral' without creating anything,
because they are fixed, but "n" deserves fast access while 'memerrmsg'
does not)
 2017-07-27 10:50:16 -03:00
Roberto Ierusalimschy 73ec04fcf3 no more 'DEADKEY'. Table traversals do not need to consider dead keys; 
if the key is dead, it cannot be given to 'next'. Instead, we now
use a 'table' tag without the collectable bit, which makes it
a unique tag good enough to reserve space.
 2017-06-12 11:21:44 -03:00
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 6d95de83c6 no more field 'base' in CallInfo (base is always equal to 'func + 1', 
with old/new vararg implementation)
 2017-05-13 10:54:47 -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 69371c4b84 'KGC_NORMAL' -> 'KGC_INC' + emergency GC signalled by flag (instead 
of mode)
 2017-04-24 13:59:26 -03:00
Roberto Ierusalimschy c7bdc0e0e8 first version of control for the generational collector 2017-04-19 14:02:50 -03:00
Roberto Ierusalimschy a3d36fe283 Upvalues collected like everything else (with mark-sweep) instead 
of reference count (simpler and better for generational mode)
 2017-04-11 15:41:09 -03:00
Roberto Ierusalimschy e4287da3a6 generational collector (still not complete) 2017-04-05 13:50:51 -03:00
Roberto Ierusalimschy f5f3df3bd1 generational collection: new attempt (still incomplete) 2017-02-23 18:07:34 -03:00
Roberto Ierusalimschy e6c1e6005a comments about gray lists 2017-02-15 16:52:13 -02:00
Roberto Ierusalimschy 2a235312f0 detail (removing spaces at end of lines) 2016-12-22 11:08:50 -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 644799537f allow more bits in 'callstatus' (use no extra space due to alignments) 2016-06-16 10:36:09 -03:00
Roberto Ierusalimschy c4e01c568a make 'hook' volatile (as it may be changed in signal handling) 2015-12-16 14:39:38 -02:00
Roberto Ierusalimschy 656b3cea1b using 'sig_atomic_t' for 'hookmask' (as it can be changed inside 
a signal)
 2015-12-14 09:54:49 -02:00
Roberto Ierusalimschy 89e3a84344 removed field 'n' from 'CallInfo' (not being used right now) 2015-11-13 10:16:51 -02:00
Roberto Ierusalimschy 33b366ec32 added counters for total and individual CallInfo entries (to allow 
better syncronization between CallInfo size and stack size)
 2015-11-02 14:01:41 -02:00
Roberto Ierusalimschy 07a2dcacbf flag CIST_REENTRY changed to CIST_FRESH (its negation); fresh invocations 
seem to be less frequent than reentries. (So, avoid setting flag on
the frequent case.)
 2015-11-02 09:43:17 -02:00
Roberto Ierusalimschy 9fae7b6d3f code for string cache generalized for "associative sets" (compiler 
will optimize away or inline the extra loops)
 2015-09-22 11:18:24 -03:00
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)
 2015-09-08 12:41:05 -03:00
Roberto Ierusalimschy bde17a419d because of debt, 'totalbytes' can be negative (and therefore its 
type must be signed)
 2015-07-04 13:33:17 -03:00
Roberto Ierusalimschy 6645bb2df4 'strcache' elements as arrays of 1 element hints that cache can 
be n-way (instead of direct mapped)
 2015-06-01 13:34:37 -03:00
Roberto Ierusalimschy ae76c39712 Bug: suspended '__le' metamethod can give wrong result 2015-04-10 14:56:25 -03:00

Roberto Ierusalimschy 3670db99b6 comments 2014-10-06 18:34:34 -03:00
Roberto Ierusalimschy 2be88d5084 'lua_Ctx' -> 'lua_Kcontext' 2014-08-01 14:33:08 -03:00
Roberto Ierusalimschy 753f2c1da4 better(?) alignment for some structures (pointers first) 2014-07-23 14:15:43 -03:00
Roberto Ierusalimschy bb12903120 type 'Udata' refers directly to structure inside the union (union 
used only for aligning purposes now)
 2014-07-18 11:46:47 -03:00
Roberto Ierusalimschy ca41b43f53 type 'TString' refers directly to the structure inside the union 
(union used only for size purposes)
 2014-07-18 10:36:14 -03:00
Roberto Ierusalimschy 56137d58ff added check for conversion 'obj2gco' (and corrections for small 
problems detected by this check)
 2014-07-18 09:17:54 -03:00
Roberto Ierusalimschy 9aec500a26 no need for field 'gch' anymore 2014-07-17 14:27:49 -03:00
Roberto Ierusalimschy 5a9cc57a5e change in GCObject: instead of being a union, it is now a structure 
with the common header of all collectable objects; union is used
only for conversions. (Goal is to be able to check that the cast
'obj2gco' can have a check to ensure that object being converted
is really a collectable object.). This is the first step in the
change.
 2014-07-17 14:09:50 -03:00
Roberto Ierusalimschy 1aa4f69b51 new type 'lua_Ctx' for continuation-function contexts (to allow type

Roberto Ierusalimschy 542b6cfc02 no need for field 'status' in structure 'CallInfo' (after removal 
of 'lua_getctx') + field 'old_allowhook' can be packed into a single
bit
 2014-06-10 15:51:21 -03:00

 2014-02-18 10:46:26 -03:00
Roberto Ierusalimschy d764cc5522 new list 'twups' to allow traversal of upvalues from dead threads

 2013-08-21 17:09:51 -03:00
Roberto Ierusalimschy ae800656c9 change in string table: string table is now independent of GC lists; all

therefore not collectable in the current cycle)
 2012-05-22 14:32:25 -03:00
