Remove Google sparsehash library.

GMenu2X now uses tr1::unordered_map instead, which results in a much smaller binary.
The Google library might have its uses when high performance is required, but for us a smaller binary is more important since that reduces startup time.

* sparsehash: initial release:
The sparsehash package contains several hash-map implementations,
similar in API to SGI's hash_map class, but with different
performance characteristics. sparse_hash_map uses very little
space overhead: 1-2 bits per entry. dense_hash_map is typically
faster than the default SGI STL implementation. This package
also includes hash-set analogues of these classes.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script). Here is a another example:
/bin/bash ./configure CONFIG_SHELL=/bin/bash
Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
configuration-related scripts to be executed by `/bin/bash'.
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

This directory contains several hash-map implementations, similar in
API to SGI's hash_map class, but with different performance
characteristics. sparse_hash_map uses very little space overhead, 1-2
bits per entry. dense_hash_map is very fast, particulary on lookup.
(sparse_hash_set and dense_hash_set are the set versions of these
routines.) On the other hand, these classes have requirements that
may not make them appropriate for all applications.
All these implementation use a hashtable with internal quadratic
probing. This method is space-efficient -- there is no pointer
overhead -- and time-efficient for good hash functions.
COMPILING
---------
To compile test applications with these classes, run ./configure
followed by make. To install these header files on your system, run

This code should work on any modern C++ system. It has been tested on
Linux (Ubuntu, Fedora, RedHat, Debian), Solaris 10 x86, FreeBSD 6.0,
OS X 10.3 and 10.4, and Windows under both VC++7 and VC++8.
USING
-----
See the html files in the doc directory for small example programs
that use these classes. It's enough to just include the header file:
#include <google/sparse_hash_map> // or sparse_hash_set, dense_hash_map, ...
google::sparse_hash_set<int, int> number_mapper;
and use the class the way you would other hash-map implementations.
(Though see "API" below for caveats.)
By default (you can change it via a flag to ./configure), these hash
implementations are defined in the google namespace.
API
---
The API for sparse_hash_map, dense_hash_map, sparse_hash_set, and
dense_hash_set, are a superset of the API of SGI's hash_map class.
See doc/sparse_hash_map.html, et al., for more information about the
API.
The usage of these classes differ from SGI's hash_map, and other
hashtable implementations, in the following major ways:
1) dense_hash_map requires you to set aside one key value as the
'empty bucket' value, set via the set_empty_key() method. This
*MUST* be called before you can use the dense_hash_map. It is
illegal to insert any elements into a dense_hash_map whose key is
equal to the empty-key.
2) For both dense_hash_map and sparse_hash_map, if you wish to delete
elements from the hashtable, you must set aside a key value as the
'deleted bucket' value, set via the set_deleted_key() method. If
your hash-map is insert-only, there is no need to call this
method. If you call set_deleted_key(), it is illegal to insert any
elements into a dense_hash_map or sparse_hash_map whose key is
equal to the deleted-key.
3) These hash-map implementation support I/O. See below.
There are also some smaller differences:
1) The constructor takes an optional argument that specifies the
number of elements you expect to insert into the hashtable. This
differs from SGI's hash_map implementation, which takes an optional
number of buckets.
2) erase() does not immediately reclaim memory. As a consequence,
erase() does not invalidate any iterators, making loops like this
correct:
for (it = ht.begin(); it != ht.end(); ++it)
if (...) ht.erase(it);
As another consequence, a series of erase() calls can leave your
hashtable using more memory than it needs to. The hashtable will
automatically compact() at the next call to insert(), but to
manually compact a hashtable, you can call
ht.resize(0)
3) While sparse_hash_map et al. accept an Allocator template argument,
they ignore it. They use malloc() and free() for all memory
allocations.
4) sparse_hash_map et al. do not use exceptions.
I/O
---
In addition to the normal hash-map operations, sparse_hash_map can
read and write hashtables to disk. (dense_hash_map also has the API,
but it has not yet been implemented, and writes will always fail.)
In the simplest case, writing a hashtable is as easy as calling two
methods on the hashtable:
ht.write_metadata(fp);
ht.write_nopointer_data(fp);
Reading in this data is equally simple:
google::sparse_hash_map<...> ht;
ht.read_metadata(fp);
ht.read_nopointer_data(fp);
The above is sufficient if the key and value do not contain any
pointers: they are basic C types or agglomorations of basic C types.
If the key and/or value do contain pointers, you can still store the
hashtable by replacing write_nopointer_data() with a custom writing
routine. See sparse_hash_map.html et al. for more information.
SPARSETABLE
-----------
In addition to the hash-map and hash-set classes, this package also
provides sparsetable.h, an array implementation that uses space
proportional to the number of elements in the array, rather than the
maximum element index. It uses very little space overhead: 1 bit per
entry. See doc/sparsetable.html for the API.
RESOURCE USAGE
--------------
* sparse_hash_map has memory overhead of about 2 bits per hash-map
entry.
* dense_hash_map has a factor of 2-3 memory overhead: if your
hashtable data takes X bytes, dense_hash_map will use 3X-4X memory
total.
Hashtables tend to double in size when resizing, creating an
additional 50% space overhead. dense_hash_map does in fact have a
significant "high water mark" memory use requirement.
sparse_hash_map, however, is written to need very little space
overhead when resizing: only a few bits per hashtable entry.
PERFORMANCE
-----------
You can compile and run the included file time_hash_map.cc to examine
the performance of sparse_hash_map, dense_hash_map, and your native
hash_map implementation on your system. One test against the
SGI hash_map implementation gave the following timing information for
a simple find() call:
SGI hash_map: 22 ns
dense_hash_map: 13 ns
sparse_hash_map: 117 ns
SGI map: 113 ns
See doc/performance.html for more detailed charts on resource usage
and performance data.

downside is that probes across groups might take longer since
groups are not contiguous in memory. Making groups the same size
as a cache-line, and ensuring they're loaded on cache-line

# This file is free software; the Free Software Foundation

# 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
# configured tree to be moved without reconfiguration.

# This was a mistake. There are at least two reasons why we must not
# use `-m 0755':
# - it causes special bits like SGID to be ignored,
# - it may be too restrictive (some setups expect 775 directories).
#
# Do not use -m 0755 and let people choose whatever they expect by
# setting umask.
#
# We cannot accept any implementation of `mkdir' that recognizes `-p'.
# Some implementations (such as Solaris 8's) are not thread-safe: if a
# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
# concurrently, both version can detect that a/ is missing, but only
# one can create it and the other will error out. Consequently we

<title>Implementation notes: sparse_hash, dense_hash, sparsetable</title>
</HEAD>
<BODY>
<h1>Implementation of sparse_hash_map, dense_hash_map, and
sparsetable</h1>
This document contains a few notes on how the data structures in this
package are implemented. This discussion refers at several points to
the classic text in this area: Knuth, <i>The Art of Computer
Programming</i>, Vol 3, Hashing.
<hr>
<h2><tt>sparsetable</tt></h2>
<p>For specificity, consider the declaration </p>
<pre>
sparsetable&lt;Foo&gt; t(100); // a sparse array with 100 elements
</pre>
<p>A sparsetable is a random container that implements a sparse array,
that is, an array that uses very little memory to store unassigned
indices (in this case, between 1-2 bits per unassigned index). For
instance, if you allocate an array of size 5 and assign a[2] = [big
struct], then a[2] will take up a lot of memory but a[0], a[1], a[3],
and a[4] will not. Array elements that have a value are called
"assigned". Array elements that have no value yet, or have had their
value cleared using erase() or clear(), are called "unassigned".
For assigned elements, lookups return the assigned value; for
unassigned elements, they return the default value, which for t is
Foo().</p>
<p>sparsetable is implemented as an array of "groups". Each group is
responsible for M array indices. The first group knows about
t[0]..t[M-1], the second about t[M]..t[2M-1], and so forth. (M is 48
by default.) At construct time, t creates an array of (99/M + 1)
groups. From this point on, all operations -- insert, delete, lookup
-- are passed to the appropriate group. In particular, any operation
on t[i] is actually performed on (t.group[i / M])[i % M].</p>
<p>Each group contains of a vector, which holds assigned values, and a
bitmap of size M, which indicates which indices are assigned. A
lookup works as follows: the group is asked to look up index i, where
i &lt; M. The group looks at bitmap[i]. If it's 0, the lookup fails.
If it's 1, then the group has to find the appropriate value in the
vector.</p>
<h3><tt>find()</tt></h3>
<p>Finding the appropriate vector element is the most expensive part of
the lookup. The code counts all bitmap entries &lt;= i that are set to
1. (There's at least 1 of them, since bitmap[i] is 1.) Suppose there
are 4 such entries. Then the right value to return is the 4th element
of the vector: vector[3]. This takes time O(M), which is a constant
since M is a constant.</p>
<h3><tt>insert()</tt></h3>
<p>Insert starts with a lookup. If the lookup succeeds, the code merely
replaces vector[3] with the new value. If the lookup fails, then the
code must insert a new entry into the middle of the vector. Again, to
insert at position i, the code must count all the bitmap entries &lt;= i
that are set to i. This indicates the position to insert into the
vector. All vector entries above that position must be moved to make
room for the new entry. This takes time, but still constant time
since the vector has size at most M.</p>
<p>(Inserts could be made faster by using a list instead of a vector to
hold group values, but this would use much more memory, since each
list element requires a full pointer of overhead.)</p>
<p>The only metadata that needs to be updated, after the actual value is
inserted, is to set bitmap[i] to 1. No other counts must be
maintained.</p>
<h3><tt>delete()</tt></h3>
<p>Deletes are similar to inserts. They start with a lookup. If it
fails, the delete is a noop. Otherwise, the appropriate entry is
removed from the vector, all the vector elements above it are moved
down one, and bitmap[i] is set to 0.</p>
<h3>iterators</h3>
<p>Sparsetable iterators pose a special burden. They must iterate over
unassigned array values, but the act of iterating should not cause an
assignment to happen -- otherwise, iterating over a sparsetable would
cause it to take up much more room. For const iterators, the matter
is simple: the iterator is merely programmed to return the default
value -- Foo() -- when dereferenced while pointing to an unassigned
entry.</p>
<p>For non-const iterators, such simple techniques fail. Instead,
dereferencing a sparsetable_iterator returns an opaque object that
acts like a Foo in almost all situations, but isn't actually a Foo.
(It does this by defining operator=(), operator value_type(), and,
most sneakily, operator&().) This works in almost all cases. If it
doesn't, an explicit cast to value_type will solve the problem:</p>
<pre>
printf("%d", static_cast&lt;Foo&gt;(*t.find(0)));
</pre>
<p>To avoid such problems, consider using get() and set() instead of an
iterator:</p>
<pre>
for (int i = 0; i &lt; t.size(); ++i)
if (t.get(i) == ...) t.set(i, ...);
</pre>
<p>Sparsetable also has a special class of iterator, besides normal and
const: nonempty_iterator. This only iterates over array values that
are assigned. This is particularly fast given the sparsetable
implementation, since it can ignore the bitmaps entirely and just
iterate over the various group vectors.</p>
<h3>Resource use</h3>
<p>The space overhead for an sparsetable of size N is N + 48N/M bits.
For the default value of M, this is exactly 2 bits per array entry.
(That's for 32-bit pointers; for machines with 64-bit pointers, it's N
+ 80N/M bits, or 2.67 bits per entry.)
A larger M would use less overhead -- approaching 1 bit per array
entry -- but take longer for inserts, deletes, and lookups. A smaller
M would use more overhead but make operations somewhat faster.</p>
<p>You can also look at some specific <A
HREF="performance.html">performance numbers</A>.</p>

<p>sparse_hash_set is a hashtable. For more information on hashtables,
see Knuth. Hashtables are basically arrays with complicated logic on
top of them. sparse_hash_set uses a sparsetable to implement the
underlying array.</p>
<p>In particular, sparse_hash_set stores its data in a sparsetable using
quadratic internal probing (see Knuth). Many hashtable
implementations use external probing, so each table element is
actually a pointer chain, holding many hashtable values.
sparse_hash_set, on the other hand, always stores at most one value in
each table location. If the hashtable wants to store a second value
at a given table location, it can't; it's forced to look somewhere
else.</p>
<h3><tt>insert()</tt></h3>
<p>As a specific example, suppose t is a new sparse_hash_set. It then
holds a sparsetable of size 32. The code for t.insert(foo) works as
follows:</p>
<p>
1) Call hash&lt;Foo&gt;(foo) to convert foo into an integer i. (hash&lt;Foo&gt; is
the default hash function; you can specify a different one in the
template arguments.)
</p><p>
2a) Look at t.sparsetable[i % 32]. If it's unassigned, assign it to
foo. foo is now in the hashtable.
</p><p>
2b) If t.sparsetable[i % 32] is assigned, and its value is foo, then
do nothing: foo was already in t and the insert is a noop.
</p><p>
2c) If t.sparsetable[i % 32] is assigned, but to a value other than
foo, look at t.sparsetable[(i+1) % 32]. If that also fails, try
t.sparsetable[(i+3) % 32], then t.sparsetable[(i+6) % 32]. In
general, keep trying the next triangular number.
</p><p>
3) If the table is now "too full" -- say, 25 of the 32 table entries
are now assigned -- grow the table by creating a new sparsetable
that's twice as big, and rehashing every single element from the
old table into the new one. This keeps the table from ever filling
up.
</p><p>
4) If the table is now "too empty" -- say, only 3 of the 32 table
entries are now assigned -- shrink the table by creating a new
sparsetable that's half as big, and rehashing every element as in
the growing case. This keeps the table overhead proportional to
the number of elements in the table.
</p>
<p>Instead of using triangular numbers as offsets, one could just use
regular integers: try i, then i+1, then i+2, then i+3. This has bad
'clumping' behavior, as explored in Knuth. Quadratic probing, using
the triangular numbers, avoids the clumping while keeping cache
coherency in the common case. As long as the table size is a power of
2, the quadratic-probing method described above will explore every
table element if necessary, to find a good place to insert.</p>
<p>(As a side note, using a table size that's a power of two has several
advantages, including the speed of calculating (i % table_size). On
the other hand, power-of-two tables are not very forgiving of a poor
hash function. Make sure your hash function is a good one! There are
plenty of dos and don'ts on the web (and in Knuth), for writing hash
functions.)</p>
<p>The "too full" value, also called the "maximum occupancy", determines
a time-space tradeoff: in general, the higher it is, the less space is
wasted but the more probes must be performed for each insert.
sparse_hash_set uses a high maximum occupancy, since space is more
important than speed for this data structure.</p>
<p>The "too empty" value is not necessary for performance but helps with
space use. It's rare for hashtable implementations to check this
value at insert() time -- after all, how will inserting cause a
hashtable to get too small? However, the sparse_hash_set
implementation never resizes on erase(); it's nice to have an erase()
that does not invalidate iterators. Thus, the first insert() after a
long string of erase()s could well trigger a hashtable shrink.</p>
<h3><tt>find()</tt></h3>
<p>find() works similarly to insert. The only difference is in step
(2a): if the value is unassigned, then the lookup fails immediately.</p>
<h3><tt>delete()</tt></h3>
<p>delete() is tricky in an internal-probing scheme. The obvious
implementation of just "unassigning" the relevant table entry doesn't
work. Consider the following scenario:</p>
<pre>
t.insert(foo1); // foo1 hashes to 4, is put in table[4]
t.insert(foo2); // foo2 hashes to 4, is put in table[5]
t.erase(foo1); // table[4] is now 'unassigned'
t.lookup(foo2); // fails since table[hash(foo2)] is unassigned
</pre>
<p>To avoid these failure situations, delete(foo1) is actually
implemented by replacing foo1 by a special 'delete' value in the
hashtable. This 'delete' value causes the table entry to be
considered unassigned for the purposes of insertion -- if foo3 hashes
to 4 as well, it can go into table[4] no problem -- but assigned for
the purposes of lookup.</p>
<p>What is this special 'delete' value? The delete value has to be an
element of type Foo, since the table can't hold anything else. It
obviously must be an element the client would never want to insert on
its own, or else the code couldn't distinguish deleted entries from
'real' entries with the same value. There's no way to determine a
good value automatically. The client has to specify it explicitly.
This is what the set_deleted_key() method does.</p>
<p>Note that set_deleted_key() is only necessary if the client actually
wants to call t.erase(). For insert-only hash-sets, set_deleted_key()
is unnecessary.</p>
<p>When copying the hashtable, either to grow it or shrink it, the
special 'delete' values are <b>not</b> copied into the new table. The
copy-time rehash makes them unnecessary.</p>
<h3>Resource use</h3>
<p>The data is stored in a sparsetable, so space use is the same as
for sparsetable. However, by default the sparse_hash_set
implementation tries to keep about half the table buckets empty, to
keep lookup-chains short. Since sparsehashmap has about 2 bits
overhead per bucket (or 2.5 bits on 64-bit systems), sparse_hash_map
has about 4-5 bits overhead per hashtable item.</p>
<p>Time use is also determined in large part by the sparsetable
implementation. However, there is also an extra probing cost in
hashtables, which depends in large part on the "too full" value. It
should be rare to need more than 4-5 probes per lookup, and usually
significantly less will suffice.</p>
<p>A note on growing and shrinking the hashtable: all hashtable
implementations use the most memory when growing a hashtable, since
they must have room for both the old table and the new table at the
same time. sparse_hash_set is careful to delete entries from the old
hashtable as soon as they're copied into the new one, to minimize this
space overhead. (It does this efficiently by using its knowledge of
the sparsetable class and copying one sparsetable group at a time.)</p>
<p>You can also look at some specific <A
HREF="performance.html">performance numbers</A>.</p>
<hr>
<h2><tt>sparse_hash_map</tt></h2>
<p>sparse_hash_map is implemented identically to sparse_hash_set. The
only difference is instead of storing just Foo in each table entry,
the data structure stores pair&lt;Foo, Value&gt;.</p>
<hr>
<h2><tt>dense_hash_set</tt></h2>
<p>The hashtable aspects of dense_hash_set are identical to
sparse_hash_set: it uses quadratic internal probing, and resizes
hashtables in exactly the same way. The difference is in the
underlying array: instead of using a sparsetable, dense_hash_set uses
a C array. This means much more space is used, especially if Foo is
big. However, it makes all operations faster, since sparsetable has
memory management overhead that C arrays do not.</p>
<p>The use of C arrays instead of sparsetables points to one immediate
complication dense_hash_set has that sparse_hash_set does not: the
need to distinguish assigned from unassigned entries. In a
sparsetable, this is accomplished by a bitmap. dense_hash_set, on the
other hand, uses a dedicated value to specify unassigned entries.
Thus, dense_hash_set has two special values: one to indicate deleted
table entries, and one to indicated unassigned table entries. At
construct time, all table entries are initialized to 'unassigned'.</p>
<p>dense_hash_set provides the method set_empty_key() to indicate the
value that should be used for unassigned entries. Like
set_deleted_key(), set_empty_key() requires a value that will not be
used by the client for any legitimate purpose. Unlike
set_deleted_key(), set_empty_key() is always required, no matter what
hashtable operations the client wishes to perform.</p>
<h3>Resource use</h3>
<p>This implementation is fast because even though dense_hash_set may not
be space efficient, most lookups are localized: a single lookup may
need to access table[i], and maybe table[i+1] and table[i+3], but
nothing other than that. For all but the biggest data structures,
these will frequently be in a single cache line.</p>
<p>This implementation takes, for every unused bucket, space as big as
the key-type. Usually between half and two-thirds of the buckets are
empty.</p>
<p>The doubling method used by dense_hash_set tends to work poorly
with most memory allocators. This is because memory allocators tend
to have memory 'buckets' which are a power of two. Since each
doubling of a dense_hash_set doubles the memory use, a single
hashtable doubling will require a new memory 'bucket' from the memory
allocator, leaving the old bucket stranded as fragmented memory.
Hence, it's not recommended this data structure be used with many
inserts in memory-constrained situations.</p>
<p>You can also look at some specific <A
HREF="performance.html">performance numbers</A>.</p>

are stored in each table entry.</p>

<h1> <a name="Google_Sparsehash_Package"></a>Google Sparsehash Package </h1>
<br>
<p>The Google sparsehash package consists of two hashtable
implementations: <i>sparse</i>, which is designed to be very space
efficient, and <i>dense</i>, which is designed to be very time
efficient. For each one, the package provides both a hash-map and a
hash-set, to mirror the classes in the common STL implementation.</p>
<p>Documentation on how to use these classes:</p>
<ul>
<li> <A HREF="sparse_hash_map.html">sparse_hash_map</A>
<li> <A HREF="sparse_hash_set.html">sparse_hash_set</A>
<li> <A HREF="dense_hash_map.html">dense_hash_map</A>
<li> <A HREF="dense_hash_set.html">dense_hash_set</A>
</ul>
<p>In addition to the hash-map (and hash-set) classes, there's also a
lower-level class that implements a "sparse" array. This class can be
useful in its own right; consider using it when you'd normally use a
<code>sparse_hash_map</code>, but your keys are all small-ish
integers.</p>
<ul>
<li> <A HREF="sparsetable.html">sparsetable</A>
</ul>
<p>There is also a doc explaining the <A
HREF="implementation.html">implementation details</A> of these
classes, for those who are curious. And finally, you can see some
<A HREF="performance.html">performance comparisons</A>, both between
the various classes here, but also between these implementations and
other standard hashtable implementations.</p>

<H2>Performance Numbers</H2>
<p>Here are some performance numbers from an example desktop machine,
taken from a version of time_hash_map that was instrumented to also
report memory allocation information (this modification is not
included by default because it required a big hack to do, including
modifying the STL code to not try to do its own freelist management).</p>
<p>Note there are lots of caveats on these numbers: they may differ from
machine to machine and compiler to compiler, and they only test a very
particular usage pattern that may not match how you use hashtables --
for instance, they test hashtables with very small keys. However,
they're still useful for a baseline comparison of the various
hashtable implementations.</p>
<p>These figures are from a 2.80GHz Pentium 4 with 2G of memory. The
'standard' hash_map and map implementations are the SGI STL code
included with <tt>gcc2</tt>. Compiled with <tt>gcc2.95.3 -g
-O2</tt></p>

<p>For good performance, the Google hash routines depend on a good
hash function: one that distributes data evenly. Many hashtable
implementations come with sub-optimal hash functions that can degrade
performance. For instance, the hash function given in Knuth's _Art of
Computer Programming_, and the default string hash function in SGI's
STL implementation, both distribute certain data sets unevenly,
leading to poor performance.</p>
<p>As an example, in one test of the default SGI STL string hash
function against the Hsieh hash function (see below), for a particular
set of string keys, the Hsieh function resulted in hashtable lookups
that were 20 times as fast as the STLPort hash function. The string
keys were chosen to be "hard" to hash well, so these results may not
be typical, but they are suggestive.</p>
<p>There has been much research over the years into good hash
functions. Here are some hash functions of note.</p>

This is a C version of sparsehash (and also, maybe, densehash) that I
wrote way back when, and served as the inspiration for the C++
version. The API for the C version is much uglier than the C++,
because of the lack of template support. I believe the class works,
but I'm not convinced it's really flexible or easy enough to use.
It would be nice to rework this C class to follow the C++ API as
closely as possible (eg have a set_deleted_key() instead of using a
#define like this code does now). I believe the code compiles and
runs, if anybody is interested in using it now, but it's subject to
major change in the future, as people work on it.

* Author: Craig Silverstein
*
* This library is intended to be used for in-memory hash tables,
* though it provides rudimentary permanent-storage capabilities.
* It attempts to be fast, portable, and small. The best algorithm
* to fulfill these goals is an internal probing hashing algorithm,
* as in Knuth, _Art of Computer Programming_, vol III. Unlike
* chained (open) hashing, it doesn't require a pointer for every
* item, yet it is still constant time lookup in practice.
*
* Also to save space, we let the contents (both data and key) that
* you insert be a union: if the key/data is small, we store it
* directly in the hashtable, otherwise we store a pointer to it.
* To keep you from having to figure out which, use KEY_PTR and
* PTR_KEY to convert between the arguments to these functions and
* a pointer to the real data. For instance:
* char key[] = "ab", *key2;
* HTItem *bck; HashTable *ht;
* HashInsert(ht, PTR_KEY(ht, key), 0);
* bck = HashFind(ht, PTR_KEY(ht, "ab"));
* key2 = KEY_PTR(ht, bck->key);
*
* There are a rich set of operations supported:
* AllocateHashTable() -- Allocates a hashtable structure and
* returns it.
* cchKey: if it's a positive number, then each key is a
* fixed-length record of that length. If it's 0,
* the key is assumed to be a \0-terminated string.
* fSaveKey: normally, you are responsible for allocating
* space for the key. If this is 1, we make a
* copy of the key for you.
* ClearHashTable() -- Removes everything from a hashtable
* FreeHashTable() -- Frees memory used by a hashtable
*
* HashFind() -- takes a key (use PTR_KEY) and returns the
* HTItem containing that key, or NULL if the
* key is not in the hashtable.
* HashFindLast() -- returns the item found by last HashFind()
* HashFindOrInsert() -- inserts the key/data pair if the key
* is not already in the hashtable, or
* returns the appropraite HTItem if it is.
* HashFindOrInsertItem() -- takes key/data as an HTItem.
* HashInsert() -- adds a key/data pair to the hashtable. What
* it does if the key is already in the table
* depends on the value of SAMEKEY_OVERWRITE.
* HashInsertItem() -- takes key/data as an HTItem.
* HashDelete() -- removes a key/data pair from the hashtable,
* if it's there. RETURNS 1 if it was there,
* 0 else.
* If you use sparse tables and never delete, the full data
* space is available. Otherwise we steal -2 (maybe -3),
* so you can't have data fields with those values.
* HashDeleteLast() -- deletes the item returned by the last Find().
*
* HashFirstBucket() -- used to iterate over the buckets in a
* hashtable. DON'T INSERT OR DELETE WHILE
* ITERATING! You can't nest iterations.
* HashNextBucket() -- RETURNS NULL at the end of iterating.
*
* HashSetDeltaGoalSize() -- if you're going to insert 1000 items
* at once, call this fn with arg 1000.
* It grows the table more intelligently.
*
* HashSave() -- saves the hashtable to a file. It saves keys ok,
* but it doesn't know how to interpret the data field,
* so if the data field is a pointer to some complex
* structure, you must send a function that takes a
* file pointer and a pointer to the structure, and
* write whatever you want to write. It should return
* the number of bytes written. If the file is NULL,
* it should just return the number of bytes it would
* write, without writing anything.
* If your data field is just an integer, not a
* pointer, just send NULL for the function.
* HashLoad() -- loads a hashtable. It needs a function that takes
* a file and the size of the structure, and expects
* you to read in the structure and return a pointer
* to it. You must do memory allocation, etc. If
* the data is just a number, send NULL.
* HashLoadKeys() -- unlike HashLoad(), doesn't load the data off disk
* until needed. This saves memory, but if you look
* up the same key a lot, it does a disk access each
* time.
* You can't do Insert() or Delete() on hashtables that were loaded
* from disk.

# more broadly. In particular, it no longer assumes ld accepts -zdefs.

# changed a little.
dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
dnl
dnl @summary figure out how to build C programs using POSIX threads
dnl
dnl This macro figures out how to build C programs using POSIX threads.
dnl It sets the PTHREAD_LIBS output variable to the threads library and
dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
dnl C compiler flags that are needed. (The user can also force certain
dnl compiler flags/libs to be tested by setting these environment
dnl variables.)
dnl
dnl Also sets PTHREAD_CC to any special C compiler that is needed for
dnl multi-threaded programs (defaults to the value of CC otherwise).
dnl (This is necessary on AIX to use the special cc_r compiler alias.)
dnl
dnl NOTE: You are assumed to not only compile your program with these
dnl flags, but also link it with them as well. e.g. you should link
dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
dnl $LIBS
dnl
dnl If you are only building threads programs, you may wish to use
dnl these variables in your default LIBS, CFLAGS, and CC:
dnl
dnl LIBS="$PTHREAD_LIBS $LIBS"
dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
dnl CC="$PTHREAD_CC"
dnl
dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
dnl default action will define HAVE_PTHREAD.
dnl
dnl Please let the authors know if this macro fails on any platform, or
dnl if you have any other suggestions or comments. This macro was based
dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
dnl We are also grateful for the helpful feedback of numerous users.

# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it

characteristics. sparse_hash_map uses very little space overhead: 1-2
bits per entry. dense_hash_map is typically faster than the default
SGI STL implementation. This package also includes hash-set analogues
of these classes.

// Author: Craig Silverstein
//
// This is just a very thin wrapper over densehashtable.h, just
// like sgi stl's stl_hash_map is a very thin wrapper over
// stl_hashtable. The major thing we define is operator[], because
// we have a concept of a data_type which stl_hashtable doesn't
// (it only has a key and a value).
//
// NOTE: this is exactly like sparse_hash_map.h, with the word
// "sparse" replaced by "dense", except for the addition of
// set_empty_key().
//
// YOU MUST CALL SET_EMPTY_KEY() IMMEDIATELY AFTER CONSTRUCTION.
//
// Otherwise your program will die in mysterious ways.
//
// In other respects, we adhere mostly to the STL semantics for
// hash-map. One important exception is that insert() may invalidate
// iterators entirely -- STL semantics are that insert() may reorder
// iterators, but they all still refer to something valid in the
// hashtable. Not so for us. Likewise, insert() may invalidate
// pointers into the hashtable. (Whether insert invalidates iterators
// and pointers depends on whether it results in a hashtable resize).
// On the plus side, delete() doesn't invalidate iterators or pointers
// at all, or even change the ordering of elements.
//
// Here are a few "power user" tips:
//
// 1) set_deleted_key():
// If you want to use erase() you *must* call set_deleted_key(),
// in addition to set_empty_key(), after construction.
// The deleted and empty keys must differ.
//
// 2) resize(0):
// When an item is deleted, its memory isn't freed right
// away. This allows you to iterate over a hashtable,
// and call erase(), without invalidating the iterator.
// To force the memory to be freed, call resize(0).
// For tr1 compatibility, this can also be called as rehash(0).
//
// 3) min_load_factor(0.0)
// Setting the minimum load factor to 0.0 guarantees that
// the hash table will never shrink.
//
// Roughly speaking:
// (1) dense_hash_map: fastest, uses the most memory unless entries are small
// (2) sparse_hash_map: slowest, uses the least memory
// (3) hash_map / unordered_map (STL): in the middle
//
// Typically I use sparse_hash_map when I care about space and/or when
// I need to save the hashtable on disk. I use hash_map otherwise. I
// don't personally use dense_hash_set ever; some people use it for
// small sets with lots of lookups.
//
// - dense_hash_map has, typically, about 78% memory overhead (if your
// data takes up X bytes, the hash_map uses .78X more bytes in overhead).
// - sparse_hash_map has about 4 bits overhead per entry.
// - sparse_hash_map can be 3-7 times slower than the others for lookup and,
// especially, inserts. See time_hash_map.cc for details.
//
// See /usr/(local/)?doc/sparsehash-*/dense_hash_map.html
// for information about how to use this class.

//
// This is just a very thin wrapper over densehashtable.h, just
// like sgi stl's stl_hash_set is a very thin wrapper over
// stl_hashtable. The major thing we define is operator[], because
// we have a concept of a data_type which stl_hashtable doesn't
// (it only has a key and a value).
//
// This is more different from dense_hash_map than you might think,
// because all iterators for sets are const (you obviously can't
// change the key, and for sets there is no value).
//
// NOTE: this is exactly like sparse_hash_set.h, with the word
// "sparse" replaced by "dense", except for the addition of
// set_empty_key().
//
// YOU MUST CALL SET_EMPTY_KEY() IMMEDIATELY AFTER CONSTRUCTION.
//
// Otherwise your program will die in mysterious ways.
//
// In other respects, we adhere mostly to the STL semantics for
// hash-map. One important exception is that insert() may invalidate
// iterators entirely -- STL semantics are that insert() may reorder
// iterators, but they all still refer to something valid in the
// hashtable. Not so for us. Likewise, insert() may invalidate
// pointers into the hashtable. (Whether insert invalidates iterators
// and pointers depends on whether it results in a hashtable resize).
// On the plus side, delete() doesn't invalidate iterators or pointers
// at all, or even change the ordering of elements.
//
// Here are a few "power user" tips:
//
// 1) set_deleted_key():
// If you want to use erase() you must call set_deleted_key(),
// in addition to set_empty_key(), after construction.
// The deleted and empty keys must differ.
//
// 2) resize(0):
// When an item is deleted, its memory isn't freed right
// away. This allows you to iterate over a hashtable,
// and call erase(), without invalidating the iterator.
// To force the memory to be freed, call resize(0).
// For tr1 compatibility, this can also be called as rehash(0).
//
// 3) min_load_factor(0.0)
// Setting the minimum load factor to 0.0 guarantees that
// the hash table will never shrink.
//
// Roughly speaking:
// (1) dense_hash_set: fastest, uses the most memory unless entries are small
// (2) sparse_hash_set: slowest, uses the least memory
// (3) hash_set / unordered_set (STL): in the middle
//
// Typically I use sparse_hash_set when I care about space and/or when
// I need to save the hashtable on disk. I use hash_set otherwise. I
// don't personally use dense_hash_set ever; some people use it for
// small sets with lots of lookups.
//
// - dense_hash_set has, typically, about 78% memory overhead (if your
// data takes up X bytes, the hash_set uses .78X more bytes in overhead).
// - sparse_hash_set has about 4 bits overhead per entry.
// - sparse_hash_set can be 3-7 times slower than the others for lookup and,
// especially, inserts. See time_hash_map.cc for details.
//
// See /usr/(local/)?doc/sparsehash-*/dense_hash_set.html
// for information about how to use this class.

//
// This is just a very thin wrapper over sparsehashtable.h, just
// like sgi stl's stl_hash_set is a very thin wrapper over
// stl_hashtable. The major thing we define is operator[], because
// we have a concept of a data_type which stl_hashtable doesn't
// (it only has a key and a value).
//
// This is more different from sparse_hash_map than you might think,
// because all iterators for sets are const (you obviously can't
// change the key, and for sets there is no value).
//
// We adhere mostly to the STL semantics for hash-map. One important
// exception is that insert() may invalidate iterators entirely -- STL
// semantics are that insert() may reorder iterators, but they all
// still refer to something valid in the hashtable. Not so for us.
// Likewise, insert() may invalidate pointers into the hashtable.
// (Whether insert invalidates iterators and pointers depends on
// whether it results in a hashtable resize). On the plus side,
// delete() doesn't invalidate iterators or pointers at all, or even
// change the ordering of elements.
//
// Here are a few "power user" tips:
//
// 1) set_deleted_key():
// Unlike STL's hash_map, if you want to use erase() you
// *must* call set_deleted_key() after construction.
//
// 2) resize(0):
// When an item is deleted, its memory isn't freed right
// away. This allows you to iterate over a hashtable,
// and call erase(), without invalidating the iterator.
// To force the memory to be freed, call resize(0).
// For tr1 compatibility, this can also be called as rehash(0).
//
// 3) min_load_factor(0.0)
// Setting the minimum load factor to 0.0 guarantees that
// the hash table will never shrink.
//
// Roughly speaking:
// (1) dense_hash_set: fastest, uses the most memory unless entries are small
// (2) sparse_hash_set: slowest, uses the least memory
// (3) hash_set / unordered_set (STL): in the middle
//
// Typically I use sparse_hash_set when I care about space and/or when
// I need to save the hashtable on disk. I use hash_set otherwise. I
// don't personally use dense_hash_set ever; some people use it for
// small sets with lots of lookups.
//
// - dense_hash_set has, typically, about 78% memory overhead (if your
// data takes up X bytes, the hash_set uses .78X more bytes in overhead).
// - sparse_hash_set has about 4 bits overhead per entry.
// - sparse_hash_set can be 3-7 times slower than the others for lookup and,
// especially, inserts. See time_hash_map.cc for details.
//
// See /usr/(local/)?doc/sparsehash-*/sparse_hash_set.html
// for information about how to use this class.
