2019-09-22st.c: Use rb_st_* prefix instead of st_* (#2479)Yusuke Endoh
The original st.c was public domain hash table implementation, but Ruby's st.c is highly modified, and its data structure is not compatiblie with the original one. Therefore, when creating an extension library to wrap C code that uses the original st.c, the symbols conflict, which leads to segfault. This changes the prefix `st_*` of st.c functions to `rb_st_*` for reflecting that they are specific to Ruby's, and avoid symbol conflicts. Notes: Merged-By: mame <mame@ruby-lang.org>
2019-08-27struct st_hash_type now free from ANYARGS卜部昌平
After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit adds function prototypes for struct st_hash_type. Honestly I don't understand why they were commented out at the first place.
2019-08-27st_foreach now free from ANYARGS卜部昌平
After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit deletes ANYARGS from st_foreach. I strongly believe that this commit should have had come with b0af0592fdd9e9d4e4b863fde006d67ccefeac21, which added extra parameter to st_foreach callbacks.

2018-10-30support theap for T_HASH. [Feature #14989]ko1
* hash.c, internal.h: support theap for small Hash. Introduce RHASH_ARRAY (li_table) besides st_table and small Hash (<=8 entries) are managed by an array data structure. This array data can be managed by theap. If st_table is needed, then converting array data to st_table data. For st_table using code, we prepare "stlike" APIs which accepts hash value and are very similar to st_ APIs. This work is based on the GSoC achievement by tacinight <tacingiht@gmail.com> and refined by ko1. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65454 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2016-12-21st.c: fix st_hash* functions [Bug #13019]nobu
Previous implementation had an issues: - macros murmur1 assumes murmur_step takes rotation value as a second argument - but murmur_step second argument is "next block" - this makes st_hash_uint and st_hash_end to not mix high bits of hash value into lower bits - this leads to pure hash behavior on doubles and mixing hashes using st_hash_uint. It didn't matter when bins amount were prime numbers, but it hurts when bins are powers of two. Mistake were created cause of attempt to co-exist Murmur1 and Murmur2 in a same code. Change it to single hash-function implementation. - block function is in a spirit of Murmur functions, but handles inter-block dependency a bit better (imho). - final block is read in bit more optimal way on CPU with unaligned word access, - final block is mixed in simple way, - finalizer is taken from MurmurHash3 (it makes most of magic :) ) (64bit finalizer is taken from http://zimbry.blogspot.ru/2011/09/better-bit-mixing-improving-on.html) Also remove ST_USE_FNV1: it lacks implementation of many functions, and looks to be abandoned Author: Sokolov Yura aka funny_falcon <funny.falcon@gmail.com> git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57134 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

[Feature #12142] See header of st.c for improvment details. You can see all of code history here: <https://github.com/vnmakarov/ruby/tree/hash_tables_with_open_addressing> This improvement is discussed at <https://bugs.ruby-lang.org/issues/12142> with many people, especially with Yura Sokolov. * st.c: improve st_table. * include/ruby/st.h: ditto. * internal.h, numeric.c, hash.c (rb_dbl_long_hash): extract a function. * ext/-test-/st/foreach/foreach.c: catch up this change. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56650 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
