CityHash v1.1.1, June 17, 2013
* Fix CityHash32() so platforms that disagree about whether 'char' is signed
use the same mathematical function. For most people this changes nothing
as most popular platforms agree with x86 about whether 'char' is signed.
* No changes to any of the functions, unless you had been using CityHash32()
despite "make check" reporting a failure on your platform.
* Slightly modernize and improve configuration and portability.
CityHash v1.1, October 22, 2012
* Add CityHash32(), intended for 32-bit platforms.
* Change existing functions to improve their hash quality and/or speed. Most
of the changes were minor, but CityHashCrc* was substantially reworked
(and made perhaps 10% slower, unfortunately).
* Improve README.
CityHash v1.0.3, October 6, 2011
* Change all the functions to improve their hash quality. Most of the
changes were minor. Special thanks to Bob Jenkins for reporting some
issues that he'd found. The speed of the functions after these changes is
roughly unchanged, except that CityHash128() and CityHash128WithSeed() are
slower.
* To improve portability, replace the one use of ssize_t with signed long.
* Improve README.
CityHash v1.0.2, May 8, 2011
* Correct a problem in CityHashCrc256(); for inputs under 240 bytes the
scheme of padding to 240 bytes was causing the empty string and an input
of exactly 240 NULs to have the same hash code. That is now fixed.
Most strings less than 240 bytes long will have a different hash than
they did in v1.0.1.
* Other hash functions are unchanged.
* Minor corrections and improvements to README.
CityHash v1.0.1, April 28, 2011
* Added README, NEWS, and COPYING. The README contains installation and
usage instructions, information on "hash quality," and other goodies.
* Improved how CityHash128() and CityHash128WithSeed() handle very short
input strings.
* Added new functions that are faster on long strings on 64-bit CPUs with
a CRC32 instruction: CityHashCrc128(), CityHashCrc128WithSeed(), and
CityHashCrc256().
* Removed our assumption that "*(const uint64*)p" and such is safe. Now we
memcpy() instead. It has no speed penalty and makes our intent explicit
to the compiler.
* Changed #include "city.h" to #include <city.h>, suggested by Robert Escriva.
* Added build system, a modified version of one contributed by Robert Escriva.
* We now use __builtin_expect if the configure script can make it work, rather
than just on gcc.
* Added a test: use "make check" to run it. If you compile CityHash in a way
that causes it to return unexpected results, the test should fail.
* Added untested big-endian support. Please let us know if you try it!
* Other than CityHash128() and CityHash128WithSeed(), the hash functions in
the previous release are unchanged.
CityHash v1, April 11, 2011

CityHash, a family of hash functions for strings.
Introduction
============
CityHash provides hash functions for strings. The functions mix the
input bits thoroughly but are not suitable for cryptography. See
"Hash Quality," below, for details on how CityHash was tested and so on.
We provide reference implementations in C++, with a friendly MIT license.
CityHash32() returns a 32-bit hash.
CityHash64() and similar return a 64-bit hash.
CityHash128() and similar return a 128-bit hash and are tuned for
strings of at least a few hundred bytes. Depending on your compiler
and hardware, it's likely faster than CityHash64() on sufficiently long
strings. It's slower than necessary on shorter strings, but we expect
that case to be relatively unimportant.
CityHashCrc128() and similar are variants of CityHash128() that depend
on _mm_crc32_u64(), an intrinsic that compiles to a CRC32 instruction
on some CPUs. However, none of the functions we provide are CRCs.
CityHashCrc256() is a variant of CityHashCrc128() that also depends
on _mm_crc32_u64(). It returns a 256-bit hash.
All members of the CityHash family were designed with heavy reliance
on previous work by Austin Appleby, Bob Jenkins, and others.
For example, CityHash32 has many similarities with Murmur3a.
Performance on long strings: 64-bit CPUs
========================================
We are most excited by the performance of CityHash64() and its variants on
short strings, but long strings are interesting as well.
CityHash is intended to be fast, under the constraint that it hash very
well. For CPUs with the CRC32 instruction, CRC is speedy, but CRC wasn't
designed as a hash function and shouldn't be used as one. CityHashCrc128()
is not a CRC, but it uses the CRC32 machinery.
On a single core of a 2.67GHz Intel Xeon X5550, CityHashCrc256 peaks at about
5 to 5.5 bytes/cycle. The other CityHashCrc functions are wrappers around
CityHashCrc256 and should have similar performance on long strings.
(CityHashCrc256 in v1.0.3 was even faster, but we decided it wasn't as thorough
as it should be.) CityHash128 peaks at about 4.3 bytes/cycle. The fastest
Murmur variant on that hardware, Murmur3F, peaks at about 2.4 bytes/cycle.
We expect the peak speed of CityHash128 to dominate CityHash64, which is
aimed more toward short strings or use in hash tables.
For long strings, a new function by Bob Jenkins, SpookyHash, is just
slightly slower than CityHash128 on Intel x86-64 CPUs, but noticeably
faster on AMD x86-64 CPUs. For hashing long strings on AMD CPUs
and/or CPUs without the CRC instruction, SpookyHash may be just as
good or better than any of the CityHash variants.
Performance on short strings: 64-bit CPUs
=========================================
For short strings, e.g., most hash table keys, CityHash64 is faster than
CityHash128, and probably faster than all the aforementioned functions,
depending on the mix of string lengths. Here are a few results from that
same hardware, where we (unrealistically) tested a single string length over
and over again:
Hash Results
------------------------------------------------------------------------------
CityHash64 v1.0.3 7ns for 1 byte, or 6ns for 8 bytes, or 9ns for 64 bytes
Murmur2 (64-bit) 6ns for 1 byte, or 6ns for 8 bytes, or 15ns for 64 bytes
Murmur3F 14ns for 1 byte, or 15ns for 8 bytes, or 23ns for 64 bytes
We don't have CityHash64 benchmarks results for v1.1, but we expect the
numbers to be similar.
Performance: 32-bit CPUs
========================
CityHash32 is the newest variant of CityHash. It is intended for
32-bit hardware in general but has been mostly tested on x86. Our benchmarks
suggest that Murmur3 is the nearest competitor to CityHash32 on x86.
We don't know of anything faster that has comparable quality. The speed rankings
in our testing: CityHash32 > Murmur3f > Murmur3a (for long strings), and
CityHash32 > Murmur3a > Murmur3f (for short strings).
Installation
============
We provide reference implementations of several CityHash functions, written
in C++. The build system is based on autoconf. It defaults the C++
compiler flags to "-g -O2", which is probably slower than -O3 if you are
using gcc. YMMV.
On systems with gcc, we generally recommend:
./configure
make all check CXXFLAGS="-g -O3"
sudo make install
Or, if your system has the CRC32 instruction, and you want to build everything:
./configure --enable-sse4.2
make all check CXXFLAGS="-g -O3 -msse4.2"
sudo make install
Note that our build system doesn't try to determine the appropriate compiler
flag for enabling SSE4.2. For gcc it is "-msse4.2". The --enable-sse4.2
flag to the configure script controls whether citycrc.h is installed when
you "make install." In general, picking the right compiler flags can be
tricky, and may depend on your compiler, your hardware, and even how you
plan to use the library.
For generic information about how to configure this software, please try:
./configure --help
Failing that, please work from city.cc and city*.h, as they contain all the
necessary code.
Usage
=====
The above installation instructions will produce a single library. It will
contain CityHash32(), CityHash64(), and CityHash128(), and their variants,
and possibly CityHashCrc128(), CityHashCrc128WithSeed(), and
CityHashCrc256(). The functions with Crc in the name are declared in
citycrc.h; the rest are declared in city.h.
Limitations
===========
1) CityHash32 is intended for little-endian 32-bit code, and everything else in
the current version of CityHash is intended for little-endian 64-bit CPUs.
All functions that don't use the CRC32 instruction should work in
little-endian 32-bit or 64-bit code. CityHash should work on big-endian CPUs
as well, but we haven't tested that very thoroughly yet.
2) CityHash is fairly complex. As a result of its complexity, it may not
perform as expected on some compilers. For example, preliminary reports
suggest that some Microsoft compilers compile CityHash to assembly that's
10-20% slower than it could be.
Hash Quality
============
We like to test hash functions with SMHasher, among other things.
SMHasher isn't perfect, but it seems to find almost any significant flaw.
SMHasher is available at http://code.google.com/p/smhasher/
SMHasher is designed to pass a 32-bit seed to the hash functions it tests.
No CityHash function is designed to work that way, so we adapt as follows:
For our functions that accept a seed, we use the given seed directly (padded
with zeroes); for our functions that don't accept a seed, we hash the
concatenation of the given seed and the input string.
The CityHash functions have the following flaws according to SMHasher:
(1) CityHash64: none
(2) CityHash64WithSeed: none
(3) CityHash64WithSeeds: did not test
(4) CityHash128: none
(5) CityHash128WithSeed: none
(6) CityHashCrc128: none
(7) CityHashCrc128WithSeed: none
(8) CityHashCrc256: none
(9) CityHash32: none
Some minor flaws in 32-bit and 64-bit functions are harmless, as we
expect the primary use of these functions will be in hash tables. We
may have gone slightly overboard in trying to please SMHasher and other
similar tests, but we don't want anyone to choose a different hash function
because of some minor issue reported by a quality test.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a

## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file

## dummy dependencies for each header file. Too bad gcc doesn't do

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

//
// This file provides a few functions for hashing strings. All of them are
// high-quality functions in the sense that they pass standard tests such
// as Austin Appleby's SMHasher. They are also fast.
//
// For 64-bit x86 code, on short strings, we don't know of anything faster than
// CityHash64 that is of comparable quality. We believe our nearest competitor
// is Murmur3. For 64-bit x86 code, CityHash64 is an excellent choice for hash
// tables and most other hashing (excluding cryptography).
//
// For 64-bit x86 code, on long strings, the picture is more complicated.
// On many recent Intel CPUs, such as Nehalem, Westmere, Sandy Bridge, etc.,
// CityHashCrc128 appears to be faster than all competitors of comparable
// quality. CityHash128 is also good but not quite as fast. We believe our
// nearest competitor is Bob Jenkins' Spooky. We don't have great data for
// other 64-bit CPUs, but for long strings we know that Spooky is slightly
// faster than CityHash on some relatively recent AMD x86-64 CPUs, for example.
// Note that CityHashCrc128 is declared in citycrc.h.
//
// For 32-bit x86 code, we don't know of anything faster than CityHash32 that
// is of comparable quality. We believe our nearest competitor is Murmur3A.
// (On 64-bit CPUs, it is typically faster to use the other CityHash variants.)
//
// Functions in the CityHash family are not suitable for cryptography.
//
// Please see CityHash's README file for more details on our performance
// measurements and so on.
//
// WARNING: This code has been only lightly tested on big-endian platforms!
// It is known to work well on little-endian platforms that have a small penalty
// for unaligned reads, such as current Intel and AMD moderate-to-high-end CPUs.
// It should work on all 32-bit and 64-bit platforms that allow unaligned reads;
// bug reports are welcome.
//
// By the way, for some hash functions, given strings a and b, the hash
// of a+b is easily derived from the hashes of a and b. This property
// doesn't hold for any hash functions in this file.
