Roberto Ierusalimschy c231a5e2b6 using unsigned int (instead of int) in 'table.sort' to avoid overflows 
(when computing the pivot and in original table size)
 2015-11-23 09:17:31 -02:00
Roberto Ierusalimschy dc9ac5b8c2 details (merging declarations with initialization) 2015-11-23 09:09:27 -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 04587b6256 macro with empty argument can be seen as macro with no argument; better 
to avoid that
 2015-11-12 16:08:58 -02:00
Roberto Ierusalimschy bde03eeb48 in 'table.sort': tighter checks for invalid order function + 
"random" pivot for larger intervals (to avoid attacks with
bad data)
 2015-11-12 16:07:25 -02:00
Roberto Ierusalimschy 330d426ffd avoid the use of deprecated functions 'luaL_checkunsigned'/ 
'lua_pushunsigned'
 2015-11-11 17:08:09 -02:00
Roberto Ierusalimschy 02340375be janitor work on 'table.sort': added comments, partition code moved 
to a separated function, code conventions updated, etc. No changes
at all in the logic/algorithm
 2015-11-06 14:07:14 -02:00
Roberto Ierusalimschy 5100bc8aa1 no need for a special case to get long strings (not that common) 2015-11-03 16:35:21 -02:00
Roberto Ierusalimschy ebb2afa54b allow 'set' macros to be used when 'L' is not available (as it was 
needed only for assertions)
 2015-11-03 16:33:10 -02:00
Roberto Ierusalimschy 7485512384 added comment and assert about dead keys 2015-11-03 16:10:44 -02:00
Roberto Ierusalimschy 46de77b219 bug: despite its name, 'luaH_getstr' did not work for strings in 
general, but only for short strings
 2015-11-03 13:47:30 -02:00
Roberto Ierusalimschy d356183402 new function 'luaS_hashlongstr' 2015-11-03 13:36:01 -02:00
Roberto Ierusalimschy e61ee8a036 in 'luaD_call', use two functions instead of one with fixed boolean 
argument + stack error handling in 'luaD_call' moved to a separated
function
 2015-11-02 16:48:49 -02:00
Roberto Ierusalimschy ff1289a361 in 'luaD_call', use two functions instead of one with fixed boolean 
argument
 2015-11-02 16:48:07 -02:00
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 8c1fb91802 macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used 
in critical time pathes, can save a few bytes without the macro)
 2015-11-02 14:09:30 -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 c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters 
only after moving them to final place (avoids checking the stack
again)
 2015-11-02 12:06:01 -02:00
Roberto Ierusalimschy 332a06bbd1 'luaO_pushvfstring' now uses 'incr_top' to increment top. 2015-11-02 12:02:35 -02:00
Roberto Ierusalimschy ffd0d1232d using more "conventional" loops in 'luaD_poscall' (probably a little 
more efficient?)
 2015-11-02 09:48:59 -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 c874abac98 with 'fast tracks', there is no need to do raw accesses in 'ipairs' 2015-10-29 13:21:04 -02:00
Roberto Ierusalimschy 789e423b32 corrected comparisons of signed (int) with unsigned (size_t) 2015-10-29 13:11:41 -02:00
Roberto Ierusalimschy 96ec8671b1 macro 'buff2num' replaced by its body (it caused more harm than good 
to readability)
 2015-10-28 16:51:47 -02:00
Roberto Ierusalimschy cc3a42b190 option 'c' in 'string.pack' accepts any string size (truncating 
if larger and padding if smaller)
 2015-10-28 15:56:51 -02:00
Roberto Ierusalimschy 6707ce6349 function prepares vararg only if it really uses them (chunks 
are always declared vararg but seldom uses them)
 2015-10-28 15:28:40 -02:00
Roberto Ierusalimschy 257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it 
is applied only to string keys
 2015-10-28 12:50:09 -02:00
Roberto Ierusalimschy ae515a346c comments for luaD_precall/luaD_poscall 2015-10-28 10:25:36 -02:00
Roberto Ierusalimschy 3cdf1d676b details (avoid 'case' inside block + avoid using one variable for 
two roles)
 2015-10-28 10:06:45 -02:00
Roberto Ierusalimschy 82129b9266 use macro 'hasjumps' to test whether expression has jumps... 2015-10-26 12:27:47 -02:00
Roberto Ierusalimschy 8004ab756f hook test in 'luaV_execute' reduced to minimum (rest done in 
'luaG_traceexec'; no difference in performance for the non-hook
case, but keeps 'luaV_execute' a little simpler) + 'base' updates
replaced by 'Protect' (which serves this rule)
 2015-10-22 12:40:47 -02:00
Roberto Ierusalimschy ee5ef0f295 hook test in 'luaV_execute' reduced to minimum (rest done in 
'luaG_traceexec'
 2015-10-22 12:40:47 -02:00
Roberto Ierusalimschy 5bdee4f810 small changes to allow 'precall' to spend time preserving 'func' 
only when needed (that is, when stack actually changes)
 2015-10-21 16:40:47 -02:00
Roberto Ierusalimschy 48098c42ff generic definitions for float types moved to before variable definitions 
(so that specific cases can redefine these generic definitions if
needed)
 2015-10-21 16:17:40 -02:00
Roberto Ierusalimschy 3ad55386c4 'condchangemem' also may need to run 'pre'/'pos' 2015-10-21 16:15:15 -02:00
Roberto Ierusalimschy caf8278710 added comments 2015-10-20 16:00:19 -02:00
Roberto Ierusalimschy f7670781cf cleaner definition for 'luaC_condGC', using 'pre'/'pos' parameters 2015-10-20 15:56:21 -02:00
Roberto Ierusalimschy df8b996bcc 'Protect' in table operations is not needed in the fast track 
+ removal of a few dead macros
 2015-10-20 15:41:35 -02:00
Roberto Ierusalimschy 75d5a8924c macro 'addbuff' was using external variable name, instead of using 
its parameter name inside the macro.
 2015-10-20 11:11:05 -02:00
Roberto Ierusalimschy 880f82d089 '*' as a number means stack size, so that "return *" returns 
all values in the stack.
 2015-10-12 13:38:19 -03:00
Roberto Ierusalimschy 1a741157cb avoid (undefined behavior) integer 'overflow' in left shift 2015-10-08 12:55:35 -03:00
Roberto Ierusalimschy 0c78de0d6d avoid calling write function with empty block 2015-10-08 12:53:49 -03:00
