Roberto Ierusalimschy 2c107e13a8 warning (comparison between signed and unsigned integers) 2018-06-15 11:18:40 -03:00
Roberto Ierusalimschy 6e600695f8 field 'sizearray' in struct 'Table' changed to 'alimit', which can 
be used as a hint for '#t'
 2018-06-15 11:14:20 -03:00
Roberto Ierusalimschy fb8fa66136 no more 'luaH_emptyobject' and comparisons of addresses of global variables 
(instead, use a different kind of nil to signal the fake entry returned
when a key is not found in a table)
 2018-06-01 13:51:34 -03:00
Roberto Ierusalimschy 34aa0c5bd7 new macros 'likely'/'unlikely' with hints for jump predictions 
(used only in errors for now)
 2018-05-30 11:25:52 -03:00
Roberto Ierusalimschy 950fbcb971 detail ('l_castU2S' should only be used over lua_Unsigned values) 2018-05-29 15:01:50 -03:00
Roberto Ierusalimschy ef8263f81f better names for macros for tags and types. 
rttype -> rawtt; ttyperaw -> withvariant; ttype -> ttypetag;
tnov -> ttype
 2018-02-26 11:16:05 -03:00
Roberto Ierusalimschy 9243c414d9 first version of empty entries in tables 
(so that, in the future, tables can contain regular nil entries)
 2018-02-23 10:16:18 -03:00
Roberto Ierusalimschy 465b474899 small reorganization of 'luaV_flttointeger'/'luaV_tointeger' 2018-02-21 09:54:26 -03:00
Roberto Ierusalimschy 1afd5a152d more generic way to handle 'gclist' 2018-02-19 17:06:56 -03:00
Roberto Ierusalimschy e2b15aa21d janitor work on casts 2018-01-28 13:13:26 -02:00
Roberto Ierusalimschy 68af7cc81a another try with table resize. 
(Old version was leaving some elements unanchored while allocating
new memory)
 2017-12-29 13:58:23 -02:00
Roberto Ierusalimschy e663a24ab0 more freedom in handling memory-allocation errors (not all allocations 
automatically raise an error), which allows fixing a bug when resizing
a table.
 2017-12-08 15:28:25 -02:00
Roberto Ierusalimschy 7622373033 using explicit tests for allocation overflow whenever possible 2017-12-07 16:59:52 -02:00
Roberto Ierusalimschy 599f1742c6 detail (typo in comments) 2017-11-23 17:29:04 -02:00
Roberto Ierusalimschy 26679ea35b new function 'luaV_flttointeger' to convert floats to integers (without 
string coercions) + string operands to bitwise operations handled
by string metamethods
 2017-11-08 12:50:23 -02:00
Roberto Ierusalimschy f96497397a new type 'StackValue' for stack elements 
(we may want to put extra info there in the future)
 2017-06-29 12:06:44 -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 b6f87491af in hash nodes, keys are stored in separate pieces to avoid wasting 
space with alignments
 2017-06-09 13:48:44 -03:00
Roberto Ierusalimschy e3d52da144 BUG: in 'computesizes', 'twotoi' overflows when a sequence has 
more than 2^30 elements.
 2017-05-19 09:57:10 -03:00
Roberto Ierusalimschy 84910e04e2 better implementation for 'hash_search', without using 'size_t' 
(simpler to implement and to explain)
 2017-05-19 09:47:00 -03:00
Roberto Ierusalimschy 3d879fbc5d reimplementation of 'luaH_getn', trying to handle numeric limits 
properly.
 2017-05-16 16:07:08 -03:00
Roberto Ierusalimschy b1b7790f7c detail ('1' -> '1u' in unsigned operation) 2017-05-09 11:39:46 -03:00
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 d103312661 details (typos in comments) 2015-11-19 17:16:22 -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 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 8950e0c049 avoid possibility of subtle arith. overflow 2015-07-04 13:32:34 -03:00

Roberto Ierusalimschy a71c0ab861 detail (removed useless '#include') 2015-05-20 13:22:30 -03:00
Roberto Ierusalimschy 65ac789565 detail (comment) 2015-04-02 18:09:51 -03:00
Roberto Ierusalimschy 63720a4290 janitor work (comments, variable names, some other details) 2015-03-30 16:51:00 -03:00
Roberto Ierusalimschy 3a91274547 details (avoid 'lint' warnings) 2015-03-30 12:42:59 -03:00
Roberto Ierusalimschy a00013c8d0 'point2int' -> 'point2uint' (to reflect its actual result type) 2015-03-03 16:53:13 -03:00
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 397ce11996 make 'hashfloat' configurable 2015-02-20 12:05:01 -02:00
Roberto Ierusalimschy 419e2cb01d detail (file does not need 'string.h') 2015-02-16 11:15:00 -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 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 3c55790ebe 'setkey' -> 'setnodekey' (to avoid conflicts with POSIX) 2015-01-05 11:52:37 -02:00
Roberto Ierusalimschy 28fdbcf393 added include for 'lprefix.h', for stuff that must be added before 
any other header file

Roberto Ierusalimschy 3a15c7ce43 size for array part of a table ('sizearray') changed from 'int' to

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
