lua/ltable.c, branch v5.4.9 A mirror of https://github.com/lua/lua https://git.lua4.win/lua/atom?h=v5.4.9 2023-10-26T19:12:25+00:00 Simpler test in 'luaH_getint' 2023-10-26T19:12:25+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2023-10-26T19:12:25+00:00 urn:sha1:81e4fce5303fdb274bc5572fb168dd766fb8208e The test whether key is inside the array part of a table uses a bit trick to avoid computing the real size of the array part.

Removed test function 'luaH_isdummy' 2022-10-21T12:18:13+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2022-10-21T12:18:13+00:00 urn:sha1:b85816b9a884cbe4cfd139a8e11ffc28ecead576 It was not being used anywhere.

Avoid taking the address of a 'TValue' field 2021-10-11T16:52:26+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2021-10-11T16:52:26+00:00 urn:sha1:0e5071b5fbcc244d9f8c4bae82e327ad59bccc3f That structure can be packed in the future. New hash function for integer keys 2021-03-29T18:47:18+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2021-03-29T18:47:18+00:00 urn:sha1:7fbe2158089898f09d741e991737f282e514ffaa When integer keys do not form a sequence, it is better to use all their bits to compute their hashes. (The previous implementation was quite bad for integer keys with common lower bits, and disastrous for integer keys changing only in their upper 32 bits.)
