+	  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.

src/sparsehash-1.6/README

@@ -0,0 +1,149 @@
+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
+'make install'.  (On Windows, the instructions are different; see
+README.windows.)  See INSTALL for more details.
+
+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.

+<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>
+
+
+<hr>
+<h2><tt>sparse_hash_set</tt></h2>
+
+<p>For specificity, consider the declaration </p>
+
+<pre>
+   sparse_hash_set&lt;Foo&gt; t;
+</pre>
+
+<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>

+<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>

+  <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>

+<p>Here are some performance numbers from an example desktop machine,

+<p>Note there are lots of caveats on these numbers: they may differ from

+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>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>

+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,

+ * 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

+# We've rewritten the inconsistency check code (from avahi), to work

+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.
