Roberto Ierusalimschy a00013c8d0 'point2int' -> 'point2uint' (to reflect its actual result type) 2015-03-03 16:53:13 -03:00
Roberto Ierusalimschy b9a1f27250 do not attempt emergency collection while building state (it is 
useless, and state can be inconsistent)
 2015-03-03 15:18:29 -03:00
Roberto Ierusalimschy 29aed28802 detail (use 'luaS_newliteral' when possible) 2015-03-03 15:17:04 -03:00
Roberto Ierusalimschy 951b562cf8 configuration for numerical types through only one #define for 
each type
 2015-03-02 13:59:01 -03:00
Roberto Ierusalimschy 6408bc0b7f new macros 'chgfltvalue'/'chgivalue' (numerical for loop does 
not need to set the type of its internal variable at each iteration)
 2015-03-02 13:04:52 -03:00
Roberto Ierusalimschy 91efb4b895 LUA_COMPAT_5_1 needs some options deprecated from 5.2 to 5.3 2015-02-28 16:22:31 -03:00

 2015-02-20 16:21:29 -02:00
Roberto Ierusalimschy 81245b1ad5 'numisinteger' (for table keys) replaced by 'luaV_tointeger' (old 
'tointeger_aux'), which can do the same job.
 2015-02-20 12:27:53 -02:00

Roberto Ierusalimschy 97f2aa5a44 bug: when manipulating other threads, there is no garanties about 
their stack space
 2015-02-19 15:06:21 -02:00
Roberto Ierusalimschy 419e2cb01d detail (file does not need 'string.h') 2015-02-16 11:15:00 -02:00
Roberto Ierusalimschy 374f6c4612 detail ('fopen' needs 'stdio.h') 2015-02-16 11:14:33 -02:00
Roberto Ierusalimschy 4bdf9962bf bug: suspended function can have its 'func' field not pointing to

 2015-02-13 14:01:17 -02:00
Roberto Ierusalimschy e0306e386f some changes in 'hashfloat' to avoid undefined (in ISO C) numerical 
conversions
 2015-02-13 11:05:34 -02:00
Roberto Ierusalimschy 2e6e53c7cc added API checks to some unprotected 'top' increments 2015-02-11 16:47:22 -02:00
Roberto Ierusalimschy 2a57d2346e detail 2015-02-09 16:05:46 -02:00
Roberto Ierusalimschy 7e425be975 bug (in 5.2): Chunk with too many lines can seg. fault 2015-02-09 15:57:45 -02:00
Roberto Ierusalimschy 0705e7b39f detail (no need to write 'double' in source) 2015-02-09 15:41:54 -02:00
Roberto Ierusalimschy 4ccc4578b3 detail (use 'l_floor' instead of 'l_mathop(floor)') 2015-02-09 13:41:56 -02:00
Roberto Ierusalimschy 5e8c162b6c detail 2015-02-05 15:50:24 -02:00
Roberto Ierusalimschy c8d6cb0136 macros 'luai_num*' (for float arithmetic operations) moved to 
llimits.h.
 2015-02-05 15:15:33 -02:00
Roberto Ierusalimschy 0edcdf49c0 added comments documenting LUA_NOCVTN2S/LUA_NOCVTS2N 2015-02-05 14:53:34 -02:00
Roberto Ierusalimschy b7dfd18612 make buffer for format specification a little larger (length modifier

 2015-02-04 10:54:31 -02:00
Roberto Ierusalimschy 8efcd411fe own implementation for 'string.format("%a")' for C89 platforms 2015-02-04 10:52:57 -02:00
Roberto Ierusalimschy 90d016980f detail ('luaL_getmetatable' does not return a boolean, but a tag) 2015-02-03 15:38:24 -02:00
Roberto Ierusalimschy b3996c55f6 LUAL_BUFFERSIZE affects the API, so it is better not to change it 
between releases of the same version. (The long double case seems
to be too rare, so that should not be a problem; moreover, that
case is related to a bug)
 2015-01-16 15:26:56 -02:00
Roberto Ierusalimschy 438a9fcc78 LUAI_MAXSHORTLEN moved from 'luaconf.h' to 'llimits.h' (does not 
affect the API and is seldom modified)
 2015-01-16 15:15:52 -02:00
Roberto Ierusalimschy 7e2015a46d size of short strings stored in a single byte, to reduce the size 
of struct 'TString'
 2015-01-16 14:54:37 -02:00
Roberto Ierusalimschy 5b01cb39b5 larger MINSTRTABSIZE (standard Lua starts with ~230 strings, after 
oppening the standard libraries)
 2015-01-16 13:41:03 -02:00
Roberto Ierusalimschy a0503305bd comments 2015-01-16 11:26:55 -02:00
Roberto Ierusalimschy 965f74525b removed macro LUAI_FIRSTPSEUDOIDX (that stuff does not need 
to be configurable)
 2015-01-13 17:50:30 -02:00
Roberto Ierusalimschy 3f2e21f0ea Long double needs a larger LUAL_BUFFERSIZE (because 
'string.format("%.99f", 1e4900)' can generate quite long strings),
but otherwise buffer can be 1~2K
 2015-01-13 15:24:22 -02:00
Roberto Ierusalimschy 3509914916 BUG (when compiled with long double): buffer overflow when formatting 
string.format("%.99f", 1e4930)
 2015-01-13 15:18:25 -02:00
Roberto Ierusalimschy ae27be40c9 better check for overflows in 'table.move' (removes restriction that 
initial position should be positive)
 2015-01-13 14:27:29 -02:00
Roberto Ierusalimschy cdd26700e8 definition for 'MAXUPVAL' moved for a more "private" place and its 
value and comment corrected to reflect current implementation
 2015-01-13 13:49:11 -02:00
Roberto Ierusalimschy a9a4bf68b0 typo in comment 2015-01-13 11:18:04 -02:00
Roberto Ierusalimschy f31cc8e342 typo in error message 2015-01-12 17:32:32 -02:00
Roberto Ierusalimschy 3c55790ebe 'setkey' -> 'setnodekey' (to avoid conflicts with POSIX) 2015-01-05 11:52:37 -02:00
Roberto Ierusalimschy 0adfa773b9 new macro 'cast_func' adds '__extension__' (in gnu compilers) when 
converting void* to function, to avoid warnings
 2015-01-05 11:51:39 -02:00
Roberto Ierusalimschy 3317f5c6d9 includes 'stddef.h' (as it uses NULL) 2015-01-05 11:48:33 -02:00
Roberto Ierusalimschy dbf911c516 detail (added -Wconversion as a comment, to be used ocasionally) 2015-01-02 11:03:52 -02:00
Roberto Ierusalimschy 3a29087cb7 'lua_setlocal' should not pop value when failing (to be consistent 
with the manual and with 'lua_setupvalue')
 2015-01-02 10:52:22 -02:00
Roberto Ierusalimschy 234fb7f695 clearer(?) code (also avoids a warning about 'c' being used 
without initialization)
 2015-01-02 10:50:28 -02:00
Roberto Ierusalimschy c077d47465 does not define _XOPEN_SOURCE when LUA_USE_C89 is defined + defining 
_XOPEN_SOURCE==0 undefines that macro
 2014-12-29 14:54:13 -02:00
Roberto Ierusalimschy 8e5290d81e all "divisions" (div,idiv,mod) by zero are not folded, to avoid 
problems during compilation + does not fold zero results, as they
can collapse with -0.0 and the ANSI test to distinguish both needs
a division by zero (which we are trying to avoid) + removed macro
'luai_numinvalidop' (as its main use case were divisions by zero)
 2014-12-29 14:49:25 -02:00
Roberto Ierusalimschy a1c37f834a detail (macro 'luai_numidiv' uses 'luai_numdiv' to compute the division) 2014-12-29 11:27:55 -02:00
Roberto Ierusalimschy 1a7868c1d5 bug: 'random' limit is 2^31-1, not RAND_MAX 2014-12-27 18:32:26 -02:00
Roberto Ierusalimschy de3933480e details 2014-12-27 18:31:43 -02:00
Roberto Ierusalimschy 50e2eb8954 change in macro 'vmcase', avoding code inside it. (Code inside the 
macro harms tools such as debuggers.)
