+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ 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 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.
+
+ Running `configure' might take a while. 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=c99 CFLAGS=-g 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 can use 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 `..'.
+
+ With a non-GNU `make', it is safer 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).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/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.

+Hi!
+
+This is an skeleton engine, it does not do much. Its been put together for
+documentation reasons and as a way to get someone started quickly.
+
+To install, grab a copy of the mysql source code and run this:
+./configure --with-mysql=/home/brian/mysql-5.1/ --libdir=/usr/local/lib/mysql/
+make install
+
+And then inside of MySQL:
+
+mysql> INSTALL PLUGIN skeleton SONAME 'libskeleton_engine.so';
+
+mysql> CREATE TABLE `d` (`a` varchar(125), b text, primary key(a)) ENGINE=skeleton DEFAULT
+CHARSET=latin1;
+Query OK, 0 rows affected (0.01 sec)
+
+You will probably need to edit the Makefile.am in the src/ tree if you want
+to build on anything other then Linux (and the Makefile assumes that the
+server was not compiled for debug).
+
+For Solaris you can enable DTrace probes by adding to configure
+--enable-dtrace
+
+Have fun!
+
+Cheers,
+ -Brian

+# 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

+ -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
+ -dlpreopen FILE link in FILE and add its symbols to lt_preloaded_symbols
+ -export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+ -export-symbols SYMFILE
+ try to export only the symbols listed in SYMFILE
+ -export-symbols-regex REGEX
+ try to export only the symbols matching REGEX
+ -LLIBDIR search LIBDIR for required installed libraries
+ -lNAME OUTPUT-FILE requires the installed library libNAME
+ -module build a library that can dlopened
+ -no-fast-install disable the fast-install mode
+ -no-install link a not-installable executable
+ -no-undefined declare that a library does not refer to external symbols
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -objectlist FILE Use a list of object files found in FILE to specify objects
+ -precious-files-regex REGEX
+ don't remove output files matching REGEX
+ -release RELEASE specify package release information
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR
+ -R[ ]LIBDIR add LIBDIR to the runtime path of programs and libraries
+ -static do not do any dynamic linking of uninstalled libtool libraries
+ -static-libtool-libs
+ do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]
+ specify library version info [each variable defaults to 0]
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename. Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created,
+only library objects (\`.lo' files) may be specified, and \`-rpath' is
+required, except when creating a convenience library.
+
+If OUTPUT-FILE ends in \`.a' or \`.lib', then a standard library is created

+/* TODO: add caching - pre-read several index entries at once */
+
+/*
+ Added optimization for full-text queries with plus-words. It was
+ implemented by sharing maximal document id (max_docid) variable
+ inside plus subtree. max_docid could be used by any word in plus
+ subtree, but it could be updated by plus-word only.
+
+ Fulltext "smarter index merge" optimization assumes that rows
+ it gets are ordered by doc_id. That is not the case when we
+ search for a word with truncation operator. It may return
+ rows in random order. Thus we may not use "smarter index merge"
+ optimization with "trunc-words".
+
+ The idea is: there is no need to search for docid smaller than
+ biggest docid inside current plus subtree or any upper plus subtree.
+
+ Examples:
+ +word1 word2
+ share same max_docid
+ max_docid updated by word1
+ +word1 +(word2 word3)
+ share same max_docid
+ max_docid updated by word1
+ +(word1 -word2) +(+word3 word4)
+ share same max_docid
+ max_docid updated by word3
+ +word1 word2 (+word3 word4 (+word5 word6))
+ three subexpressions (including the top-level one),
+ every one has its own max_docid, updated by its plus word.
+ but for the search word6 uses
+ max(word1.max_docid, word3.max_docid, word5.max_docid),
+ while word4 uses, accordingly,
+ max(word1.max_docid, word3.max_docid).

+ Check for underlying table conformance
+
+ SYNOPSIS
+ check_definition()
+ t1_keyinfo in First table key definition
+ t1_recinfo in First table record definition
+ t1_keys in Number of keys in first table
+ t1_recs in Number of records in first table
+ t2_keyinfo in Second table key definition
+ t2_recinfo in Second table record definition
+ t2_keys in Number of keys in second table
+ t2_recs in Number of records in second table
+ strict in Strict check switch
+
+ DESCRIPTION
+ This function compares two MyISAM definitions. By intention it was done
+ to compare merge table definition against underlying table definition.
+ It may also be used to compare dot-frm and MYI definitions of MyISAM
+ table as well to compare different MyISAM table definitions.
+
+ For merge table it is not required that number of keys in merge table
+ must exactly match number of keys in underlying table. When calling this
+ function for underlying table conformance check, 'strict' flag must be
+ set to false, and converted merge definition must be passed as t1_*.
+
+ Otherwise 'strict' flag must be set to 1 and it is not required to pass
+ converted dot-frm definition as t1_*.
+
+ RETURN VALUE
+ 0 - Equal definitions.
+ 1 - Different definitions.
+
+ TODO
+ - compare FULLTEXT keys;
+ - compare SPATIAL keys;
+ - compare FIELD_SKIP_ZERO which is converted to FIELD_NORMAL correctly
+ (should be corretly detected in table2myisam).

+/* Describe, check and repair of MyISAM tables */
+
+/*
+ About checksum calculation.
+
+ There are two types of checksums. Table checksum and row checksum.
+
+ Row checksum is an additional byte at the end of dynamic length
+ records. It must be calculated if the table is configured for them.
+ Otherwise they must not be used. The variable
+ MYISAM_SHARE::calc_checksum determines if row checksums are used.
+ MI_INFO::checksum is used as temporary storage during row handling.
+ For parallel repair we must assure that only one thread can use this
+ variable. There is no problem on the write side as this is done by one
+ thread only. But when checking a record after read this could go
+ wrong. But since all threads read through a common read buffer, it is
+ sufficient if only one thread checks it.
+
+ Table checksum is an eight byte value in the header of the index file.
+ It can be calculated even if row checksums are not used. The variable
+ MI_CHECK::glob_crc is calculated over all records.
+ MI_SORT_PARAM::calc_checksum determines if this should be done. This
+ variable is not part of MI_CHECK because it must be set per thread for
+ parallel repair. The global glob_crc must be changed by one thread
+ only. And it is sufficient to calculate the checksum once only.

+ Threaded repair of table using sorting
+
+ SYNOPSIS
+ mi_repair_parallel()
+ param Repair parameters
+ info MyISAM handler to repair
+ name Name of table (for warnings)
+ rep_quick set to <> 0 if we should not change data file
+
+ DESCRIPTION
+ Same as mi_repair_by_sort but do it multithreaded
+ Each key is handled by a separate thread.
+ TODO: make a number of threads a parameter
+
+ In parallel repair we use one thread per index. There are two modes:
+
+ Quick
+
+ Only the indexes are rebuilt. All threads share a read buffer.
+ Every thread that needs fresh data in the buffer enters the shared
+ cache lock. The last thread joining the lock reads the buffer from
+ the data file and wakes all other threads.
+
+ Non-quick
+
+ The data file is rebuilt and all indexes are rebuilt to point to
+ the new record positions. One thread is the master thread. It
+ reads from the old data file and writes to the new data file. It
+ also creates one of the indexes. The other threads read from a
+ buffer which is filled by the master. If they need fresh data,
+ they enter the shared cache lock. If the masters write buffer is
+ full, it flushes it to the new data file and enters the shared
+ cache lock too. When all threads joined in the lock, the master
+ copies its write buffer to the read buffer for the other threads
+ and wakes them.
+
+ RESULT
+ 0 ok
+ <>0 Error

+
+ NOTE
+
+ Dynamic Records With Non-Quick Parallel Repair
+
+ For non-quick parallel repair we use a synchronized read/write
+ cache. This means that one thread is the master who fixes the data
+ file by reading each record from the old data file and writing it
+ to the new data file. By doing this the records in the new data
+ file are written contiguously. Whenever the write buffer is full,
+ it is copied to the read buffer. The slaves read from the read
+ buffer, which is not associated with a file. Thus read_cache.file
+ is -1. When using _mi_read_cache(), the slaves must always set
+ flag to READING_NEXT so that the function never tries to read from
+ file. This is safe because the records are contiguous. There is no
+ need to read outside the cache. This condition is evaluated in the
+ variable 'parallel_flag' for quick reference. read_cache.file must
+ be >= 0 in every other case.
+
+ RETURN
+ -1 end of file
+ 0 ok
+ > 0 error

+ Update statistics for each part of an index
+
+ SYNOPSIS
+ update_key_parts()
+ keyinfo IN Index information (only key->keysegs used)
+ rec_per_key_part OUT Store statistics here
+ unique IN Array of (#distinct tuples)
+ notnull_tuples IN Array of (#tuples), or NULL
+ records Number of records in the table
+
+ DESCRIPTION
+ This function is called produce index statistics values from unique and
+ notnull_tuples arrays after these arrays were produced with sequential
+ index scan (the scan is done in two places: chk_index() and
+ sort_key_write()).
+
+ This function handles all 3 index statistics collection methods.
+
+ Unique is an array:
+ unique[0]= (#different values of {keypart1}) - 1
+ unique[1]= (#different values of {keypart1,keypart2} tuple)-unique[0]-1
+ ...
+
+ For MI_STATS_METHOD_IGNORE_NULLS method, notnull_tuples is an array too:
+ notnull_tuples[0]= (#of {keypart1} tuples such that keypart1 is not NULL)
+ notnull_tuples[1]= (#of {keypart1,keypart2} tuples such that all
+ keypart{i} are not NULL)
+ ...
+ For all other statistics collection methods notnull_tuples==NULL.
+
+ Output is an array:
+ rec_per_key_part[k] =
+ = E(#records in the table such that keypart_1=c_1 AND ... AND
+ keypart_k=c_k for arbitrary constants c_1 ... c_k)
+
+ = {assuming that values have uniform distribution and index contains all
+ tuples from the domain (or that {c_1, ..., c_k} tuple is choosen from
+ index tuples}
+
+ = #tuples-in-the-index / #distinct-tuples-in-the-index.
+
+ The #tuples-in-the-index and #distinct-tuples-in-the-index have different
+ meaning depending on which statistics collection method is used:
+
+ MI_STATS_METHOD_* how are nulls compared? which tuples are counted?
+ NULLS_EQUAL NULL == NULL all tuples in table
+ NULLS_NOT_EQUAL NULL != NULL all tuples in table
+ IGNORE_NULLS n/a tuples that don't have NULLs

+ SYNOPSIS
+ _mi_read_dynamic_record()
+ info MI_INFO pointer to table.
+ filepos From where to read the record.
+ buf Destination for record.
+
+ NOTE
+
+ If a write buffer is active, it needs to be flushed if its contents
+ intersects with the record to read. We always check if the position
+ of the first byte of the write buffer is lower than the position
+ past the last byte to read. In theory this is also true if the write
+ buffer is completely below the read segment. That is, if there is no
+ intersection. But this case is unusual. We flush anyway. Only if the
+ first byte in the write buffer is above the last byte to read, we do
+ not flush.
+
+ A dynamic record may need several reads. So this check must be done
+ before every read. Reading a dynamic record starts with reading the
+ block header. If the record does not fit into the free space of the
+ header, the block may be longer than the header. In this case a
+ second read is necessary. These one or two reads repeat for every
+ part of the record.

+
+ The quick table is an array of 16-bit values. There exists one value

+ In most cases table_bits is 9. So there are 512 16-bit values.
+
+ If the high-order bit (16) is set (IS_CHAR) then the array slot for
+ this value is a valid Huffman code for a resulting byte value.
+
+ The low-order 8 bits (1..8) are the resulting byte value.
+
+ Bits 9..14 are the length of the Huffman code for this byte value.
+ This means so many bits from the input stream were needed to
+ represent this byte value. The remaining bits belong to later
+ Huffman codes. This also means that for every Huffman code shorter
+ than table_bits there are multiple entires in the array, which
+ differ just in the unused bits.
+
+ If the high-order bit (16) is clear (0) then the remaining bits are
+ the position of the remaining Huffman decode tree segment behind the

+ the tree until two byte values (and no branch) are found. Add one to
+ each level when returning back from each recursion stage.
+
+ 'end' is used for error checking only. A clean tree terminates
+ before reaching 'end'. Hence the exact value of 'end' is not too
+ important. However having it higher than necessary could lead to
+ misbehaviour should 'next' jump into the dirty area.
+
+ RETURN
+ length Length of longest Huffman code in bits.
+ >= OFFSET_TABLE_SIZE Error, broken tree. It does not end before 'end'.

+
+ SEARCH_FIND is used for an exact key search. The combination
+ SEARCH_FIND | SEARCH_UPDATE is used in write/update/delete

+ counts in key comparison and hence, emtpy strings ('', string length
+ zero, but not NULL) compare less that strings starting with control
+ characters and these in turn compare less than strings starting with
+ blanks.
+
+ When estimating the number of records in a key range, we request an
+ exact search for the minimum key. This translates into a plain
+ SEARCH_FIND flag. Using this alone would lead to a 'skip_end_space'
+ compare. Empty strings would be expected above control characters.
+ Their keys would not be found because they are located below control
+ characters.
+
+ This is the reason that we add the SEARCH_UPDATE flag here. It makes
+ the key estimation compare in the same way like key write operations
+ do. Olny so we will find the keys where they have been inserted.
+
+ Adding the flag unconditionally does not hurt as it is used in the
+ above mentioned condition only. So it can safely be used together
+ with other flags.

+
+ SYNOPSIS
+ _mi_seq_search()
+ info Open table information.
+ keyinfo Key definition information.
+ page Key page (beginning).
+ key Search key.
+ key_len Length to use from search key or USE_WHOLE_KEY
+ comp_flag Search flags like SEARCH_SAME etc.
+ ret_pos RETURN Position in key page behind this key.
+ buff RETURN Copy of previous or identical unpacked key.
+ last_key RETURN If key is last in page.
+
+ DESCRIPTION
+ Used instead of _mi_bin_search() when key is packed.
+ Puts smaller or identical key in buff.
+ Key is searched sequentially.
+
+ RETURN
+ > 0 Key in 'buff' is smaller than search key.
+ 0 Key in 'buff' is identical to search key.
+ < 0 Not found.

+ else 2 bytes. Each value is 'field_length' bytes big. If there
+ are more distinct column values than fit into the buffer, we
+ give up with this tree. BLOBs and VARCHARs do not have a
+ tree_buff as it can only be used with fixed length columns.
+ For the special case of field length == 1, we handle only the
+ case that there is only one distinct value in the table(s).
+ Otherwise, we can have a maximum of 256 distinct values. This
+ is then handled by the normal Huffman tree build.
+
+ Another limit for collecting distinct column values is the
+ number of values itself. Since we would need to build a
+ Huffman tree for the values, we are limited by the 'IS_OFFSET'
+ constant. This constant expresses a bit which is used to
+ determine if a tree element holds a final value or an offset
+ to a child element. Hence, all values and offsets need to be
+ smaller than 'IS_OFFSET'. A tree element is implemented with
+ two integer values, one for the left branch and one for the
+ right branch. For the extreme case that the first element
+ points to the last element, the number of integers in the tree
+ must be less or equal to IS_OFFSET. So the number of elements
+ must be less or equal to IS_OFFSET / 2.
+
+ WARNING: At first, we insert a pointer into the record buffer
+ as the key for the tree. If we got a new distinct value, which
+ is really inserted into the tree, instead of being counted
+ only, we will copy the column value from the record buffer to
+ 'tree_buff' and adjust the key pointer of the tree accordingly.

+ Fake the counts to get big Huffman codes.
+
+ SYNOPSIS
+ fakebigcodes()
+ huff_counts A pointer to the counts array.
+ end_count A pointer past the counts array.
+
+ DESCRIPTION
+
+ Huffman coding works by removing the two least frequent values from
+ the list of values and add a new value with the sum of their
+ incidences in a loop until only one value is left. Every time a
+ value is reused for a new value, it gets one more bit for its
+ encoding. Hence, the least frequent values get the longest codes.
+
+ To get a maximum code length for a value, two of the values must
+ have an incidence of 1. As their sum is 2, the next infrequent value
+ must have at least an incidence of 2, then 4, 8, 16 and so on. This
+ means that one needs 2**n bytes (values) for a code length of n
+ bits. However, using more distinct values forces the use of longer
+ codes, or reaching the code length with less total bytes (values).
+
+ To get 64(32)-bit codes, I sort the counts by decreasing incidence.
+ I assign counts of 1 to the two most frequent values, a count of 2
+ for the next one, then 4, 8, and so on until 2**64-1(2**30-1). All
+ the remaining values get 1. That way every possible byte has an
+ assigned code, though not all codes are used if not all byte values
+ are present in the column.
+
+ This strategy would work with distinct column values too, but
+ requires that at least 64(32) values are present. To make things
+ easier here, I cancel all distinct column values and force byte
+ compression for all columns.
