This seems to dramatically improve the speed for simple keys. Thank Zilong Tan for the suggestion. Reference: - https://github.com/stefanocasazza/ULib - https://nothings.org/computer/judy/ * Allow to optionally use linear probing which usually has better performance for random input. Double hashing is still the default as it is more robust to certain non-random input. * Added Wang's integer hash function (not used by default). This hash function is more robust to certain non-random input. 2011-02-14 (0.2.5): * Allow to declare global functions. 2009-09-26 (0.2.4): * Improve portability 2008-09-19 (0.2.3): * Corrected the example * Improved interfaces 2008-09-11 (0.2.2): * Improved speed a little in kh_put() 2008-09-10 (0.2.1): * Added kh_clear() * Fixed a compiling error 2008-09-02 (0.2.0): * Changed to token concatenation which increases flexibility. 2008-08-31 (0.1.2): * Fixed a bug in kh_get(), which has not been tested previously. 2008-08-31 (0.1.1): * Added destructor */ #ifndef __AC_KHASH_H #define __AC_KHASH_H /*! @header Generic hash table library. */ #define AC_VERSION_KHASH_H "0.2.6" #include #include #include #include "../inline_helper.h" // hooks for memory allocator, C-runtime allocator used per default #ifndef KHASH_MALLOC #define KHASH_MALLOC malloc #endif #ifndef KHASH_REALLOC #define KHASH_REALLOC realloc #endif #ifndef KHASH_CALLOC #define KHASH_CALLOC calloc #endif #ifndef KHASH_FREE #define KHASH_FREE free #endif #if UINT_MAX == 0xffffffffu typedef unsigned int khuint32_t; typedef signed int khint32_t; #elif ULONG_MAX == 0xffffffffu typedef unsigned long khuint32_t; typedef signed long khint32_t; #endif #if ULONG_MAX == ULLONG_MAX typedef unsigned long khuint64_t; typedef signed long khint64_t; #else typedef unsigned long long khuint64_t; typedef signed long long khint64_t; #endif #if UINT_MAX == 0xffffu typedef unsigned int khuint16_t; typedef signed int khint16_t; #elif USHRT_MAX == 0xffffu typedef unsigned short khuint16_t; typedef signed short khint16_t; #endif #if UCHAR_MAX == 0xffu typedef unsigned char khuint8_t; typedef signed char khint8_t; #endif typedef double khfloat64_t; typedef float khfloat32_t; typedef khuint32_t khuint_t; typedef khuint_t khiter_t; #define __ac_isempty(flag, i) ((flag[i>>5]>>(i&0x1fU))&1) #define __ac_isdel(flag, i) (0) #define __ac_iseither(flag, i) __ac_isempty(flag, i) #define __ac_set_isdel_false(flag, i) (0) #define __ac_set_isempty_false(flag, i) (flag[i>>5]&=~(1ul<<(i&0x1fU))) #define __ac_set_isempty_true(flag, i) (flag[i>>5]|=(1ul<<(i&0x1fU))) #define __ac_set_isboth_false(flag, i) __ac_set_isempty_false(flag, i) #define __ac_set_isdel_true(flag, i) ((void)0) // specializations of https://github.com/aappleby/smhasher/blob/master/src/MurmurHash2.cpp khuint32_t PANDAS_INLINE murmur2_32to32(khuint32_t k){ const khuint32_t SEED = 0xc70f6907UL; // 'm' and 'r' are mixing constants generated offline. // They're not really 'magic', they just happen to work well. const khuint32_t M_32 = 0x5bd1e995; const int R_32 = 24; // Initialize the hash to a 'random' value khuint32_t h = SEED ^ 4; //handle 4 bytes: k *= M_32; k ^= k >> R_32; k *= M_32; h *= M_32; h ^= k; // Do a few final mixes of the hash to ensure the "last few // bytes" are well-incorporated.
