Roberto Ierusalimschy	0acd55898d	Added gcc option '-Wconversion' No warnings for standard numerical types. Still pending alternative numerical types.	3 months ago
Roberto Ierusalimschy	94b503d95e	Encoding of table indices (hres) must use C indices As the encoding of array indices is (~index), 0 is encoded as -1 and INT_MAX is encoded as INT_MIN.	5 months ago
Roberto Ierusalimschy	5edacafcfa	Yet another representation for arrays This "linear" representation (see ltable.h for details) has worse locality than cells, but the simpler access code seems to compensate that.	7 months ago
Roberto Ierusalimschy	9fa63a6268	Some 'unsigned int' changed to 'unsigned' 'unsigned int' is too long sometimes. (We already write 'long' instead of 'long int'...)	8 months ago
Roberto Ierusalimschy	0593256707	'luaH_get' functions return tag of the result Undoing previous commit. Returning TValue increases code size without any visible gains. Returning the tag is a little simpler than returning a special code (HOK/HNOTFOUND) and the tag is useful by itself in some cases.	8 months ago
Roberto Ierusalimschy	ce6f5502c9	'luaH_get' functions return 'TValue' Instead of receiving a parameter telling them where to put the result of the query, these functions return the TValue directly. (That is, they return a structure.)	8 months ago
Roberto Ierusalimschy	ba71060381	Removed "bulk operations" Negligible performance gains don't justify extra complexity.	8 months ago
Roberto Ierusalimschy	3823fc6c81	Added "bulk operations" to arrays A few operations on arrays can be performed "in bulk", treating all tags of a cell as a simple (or a few) word(s).	8 months ago
Roberto Ierusalimschy	d862da6d04	Optimizations for 'lua_rawgeti' and 'lua_rawseti' 'lua_rawgeti' now uses "fast track"; 'lua_rawseti' still calls 'luaH_setint', but the latter was recoded to avoid extra overhead when writing to the array part after 'alimit'.	10 months ago
Roberto Ierusalimschy	52b899d60d	Simpler coding for new representation for arrays With the tags comming first in a cell, we can define the whole cell as a C type and let C do part of the address computations.	12 months ago
Roberto Ierusalimschy	b8a9d14032	Details Comments and parameter name in header file.	1 year ago
Roberto Ierusalimschy	08a077d673	Full implementation of new representation for arrays	1 year ago
Roberto Ierusalimschy	43c8e5bded	Full abstraction for representation of array values	1 year ago
Roberto Ierusalimschy	819bd51d87	Some cleaning in the new table API	2 years ago
Roberto Ierusalimschy	f8d30826dd	New table API for 'set' functions	2 years ago
Roberto Ierusalimschy	351ccd7332	Towards a new implementation of arrays The array part of a table wastes too much space, due to padding. To avoid that, we need to store values in the array as something different from a TValue. Therefore, the API for table access should not assume that any value in a table lives in a TValue. This commit is the first step to remove that assumption: functions luaH_get, instead of returning a TValue where the value lives, receive a TValue where to put the value being accessed. (We still have to change the luaH_set* functions.)	2 years ago
Roberto Ierusalimschy	934e77a286	Details - Better comments about short strings in opcodes. - luaH_newkey made static.	2 years ago
Roberto Ierusalimschy	8047b2d03e	Tables have a 'lastfree' information only when needed Only tables with some minimum number of entries in their hash part have a 'lastfree' field, kept in a header before the node vector.	2 years ago
Roberto Ierusalimschy	b85816b9a8	Removed test function 'luaH_isdummy' It was not being used anywhere.	2 years ago
Roberto Ierusalimschy	23051e830a	Changes in the API of 'luaH_set' and related functions Functions to set values in a table (luaH_set, luaH_newkey, etc.) receive the new value, instead of returning a slot where to put the value.	4 years ago
Roberto Ierusalimschy	7c3cb71fa4	Free bit 7 of GC 'marked' field Tables were using this bit to indicate their array sizes were real ('isrealasize'), but this bit can be useful for tests. Instead, they can use bit 7 of their 'flag' field for that purpose. (There are only six fast-access metamethods.) This 'flag' field only exists in tables, so this use does not affect other types.	4 years ago
Roberto Ierusalimschy	0ddc0f47bd	Several details about 5.4.0 rc1 Corrected several small details: added 'const', adjusts in tabs x spaces, removed unused #includes and #defines, misspellings, etc.	5 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	6e600695f8	field 'sizearray' in struct 'Table' changed to 'alimit', which can be used as a hint for '#t'	6 years ago
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)	7 years ago
Roberto Ierusalimschy	9243c414d9	first version of empty entries in tables (so that, in the future, tables can contain regular nil entries)	7 years ago
Roberto Ierusalimschy	b6f87491af	in hash nodes, keys are stored in separate pieces to avoid wasting space with alignments	8 years ago
Roberto Ierusalimschy	e39ee2cc58	'luaH_getn' must return 'lua_Unsigned' (or 'lua_Integer'), to allow the boundary-search algorithm to use 'maxinteger' when it cannot find a good upper bound.	8 years ago
Roberto Ierusalimschy	2a235312f0	detail (removing spaces at end of lines)	8 years ago
Roberto Ierusalimschy	7b1fba69b7	using 'lastfree == NULL' to signal that table is using the dummy node for its hash part + new macro 'allocsizenode'	8 years ago
Roberto Ierusalimschy	46de77b219	bug: despite its name, 'luaH_getstr' did not work for strings in general, but only for short strings	9 years ago
Roberto Ierusalimschy	3a15c7ce43	size for array part of a table ('sizearray') changed from 'int' to 'unsigned int', which allows twice as many elements in the array part	10 years ago
Roberto Ierusalimschy	07c7fdb9df	simpler definition for 'setobj' (trust the compiler for the assignment)	10 years ago
Roberto Ierusalimschy	8ef9e8460e	bug (GC can collect long identifier during parser) + change (using a single constant table for all functions in a chunk)	11 years ago
Roberto Ierusalimschy	d4e6b75098	"integer" keys in tables are now lua_Integer, not 'int'.	12 years ago
Roberto Ierusalimschy	89b59eee73	bug: __newindex metamethod may not work if metatable is its own metatable + luaV_settable does not create entry when there is a metamethod (and therefore entry is useless)	13 years ago
Roberto Ierusalimschy	92afcf2823	no more 'luaH_setstr (used only once) + 'luaH_setint' receives value to be set.	13 years ago
Roberto Ierusalimschy	d9ea6eca7c	macro 'key2tal' replaced by 'gkey' (as both were equal)	15 years ago
Roberto Ierusalimschy	fbf866a1a5	macro 'gkey' returns a "real" TValue*	15 years ago
Roberto Ierusalimschy	3135a6bbab	luaH_[gs]etnum renamed to luaH_[gs]etint (as they only accept integers, not generic numbers)	15 years ago
