+About HandlerSocket
+
+HandlerSocket is a NoSQL plugin for MySQL. It works as a daemon inside the
+mysqld process, accept tcp connections, and execute requests from clients.
+HandlerSocket does not support SQL queries. Instead, it supports simple CRUD
+operations on tables.
+
+Because of the following reasons, HandlerSocket is much faster than the
+mysqld/libmysql pair in some circumstances:
+
+  - HandlerSocket manipulates data without parsing SQL, which causes less
+    CPU usage.
+  - HandlerSocket reads many requests from clients and executes their
+    requests in bulk, which causes less CPU and disk usage.
+  - HandlerSocket client/server protocol is more compact than the 
+    mysql/libmysql pair, which causes less network usage.
+
+The current version of HandlerSocket only works with GNU/Linux. The source
+archive of HandlerSocket includes a C++ and a Perl client libraries.
+Here is a list of client libraries for other languages:
+
+  - PHP
+    http://openpear.org/package/Net_HandlerSocket
+    http://github.com/tz-lom/HSPHP
+    http://code.google.com/p/php-handlersocket/
+  - Java
+    http://code.google.com/p/hs4j/
+    http://code.google.com/p/handlersocketforjava/
+  - Python

+About HandlerSocket
+
+HandlerSocket is a NoSQL plugin for MySQL. It works as a daemon inside the
+mysqld process, accept tcp connections, and execute requests from clients.
+HandlerSocket does not support SQL queries. Instead, it supports simple CRUD
+operations on tables.
+
+Because of the following reasons, HandlerSocket is much faster than the
+mysqld/libmysql pair in some circumstances:
+
+  - HandlerSocket manipulates data without parsing SQL, which causes less
+    CPU usage.
+  - HandlerSocket reads many requests from clients and executes their
+    requests in bulk, which causes less CPU and disk usage.
+  - HandlerSocket client/server protocol is more compact than the 
+    mysql/libmysql pair, which causes less network usage.
+
+The current version of HandlerSocket only works with GNU/Linux. The source
+archive of HandlerSocket includes a C++ and a Perl client libraries.
+Here is a list of other language bindings:

+1. Building Handlersocket
+
+ Handlersocket mainly consists of libhsclient, handlersocket, and C++/Perl clients. libhsclient is a common library shared from both client and server(plugin). handlersocket is a MySQL daemon plugin.
+ To build Handlersocket, you need both MySQL source code and MySQL binary. It is not required to pre-build MySQL source code, but source itself is needed because Handlersocket depends on MySQL header files that only MySQL source distribution contains. MySQL binary is just a normal MySQL binary distribution. You can use official MySQL binaries provided by Oracle.
+ Since Handlersocket uses daemon plugin interface supported from MySQL 5.1,
+MySQL 5.1 or higher version is required.
+ Please make sure that you use identical MySQL version between MySQL source
+and MySQL binary. Otherwise you might encounter serious problems (i.e. server
+crash, etc). 
+ Here are steps to build Handlersocket.
+
+* Get MySQL source code
+
+* Get MySQL binary
+
+* Build Handlersocket
+  $ ./autogen.sh
+  $ ./configure --with-mysql-source=/work/mysql-5.1.50 --with-mysql-bindir=/work/mysql-5.1.50-linux-x86_64-glibc23/bin  --with-mysql-plugindir=/work/mysql-5.1.50-linux-x86_64-glibc23/lib/plugin
+
+ --with-mysql-source refers to the top of MySQL source directory (which
+contains the VERSION file or the configure.in file), --with-mysql-bindir
+refers to where MySQL binary executables (i.e. mysql_config) are located,
+and --with-mysql-plugindir refers to a plugin directory where plugin
+libraries (*.so) are installed. 
+
+  $ make
+  $ sudo make install
+
+ Both libhsclient and the handlersocket plugin will be installed.
+
+ 
+2. Using Handlersocket
+
+Append configuration options for handlersocket to my.cnf.
+
+  [mysqld]
+  loose_handlersocket_port = 9998
+    # the port number to bind to (for read requests)
+  loose_handlersocket_port_wr = 9999
+    # the port number to bind to (for write requests)
+  loose_handlersocket_threads = 16
+    # the number of worker threads (for read requests)
+  loose_handlersocket_threads_wr = 1
+    # the number of worker threads (for write requests)
+  open_files_limit = 65535
+    # to allow handlersocket accept many concurrent
+    # connections, make open_files_limit as large as
+    # possible.
+
+Log in to mysql as root, and execute the following query.
+
+  mysql> install plugin handlersocket soname 'handlersocket.so';
+
+If handlersocket.so is successfully installed, it starts
+accepting connections on port 9998 and 9999. Running
+'show processlist' should show handlersocket worker threads.
+
+-----------------------------------------------------------------
+On the client side, you need to install libhsclient for c++ apps
+and perl-Net-HandlerSocket for perl apps. They do not require
+MySQL to compile.
+
+  $ ./autogen.sh
+  $ ./configure --disable-handlersocket-server
+  $ make
+  $ sudo make install
+  $ cd perl-Net-HandlerSocket
+  $ perl Makefile.PL
+  $ make
+  $ sudo make install
+
+-----------------------------------------------------------------
+Alternatively, you can use the rpm installation. If your OS
+supports rpms, you can use the following commands to build and
+install handlersocket rpm packages.
+
+(Server side, installs HandlerSocket plugin)
+  $ ./autogen.sh
+  $ ./configure --with-mysql-source=/work/mysql-5.1.50 --with-mysql-bindir=/work/mysql-5.1.50-linux-x86_64-glibc23/bin  --with-mysql-plugindir=/work/mysql-5.1.50-linux-x86_64-glibc23/lib/plugin
+  $ make rpm_cli
+  $ sudo rpm -U dist/RPMS/*/libhsclient*.rpm
+  $ make rpm_c
+  $ sudo rpm -U dist/RPMS/*/handlersocket*.rpm
+
+(Client side, installs client libraries)
+  $ ./autogen.sh
+  $ ./configure --disable-handlersocket-server
+  $ make rpm_cli
+  $ sudo rpm -U dist/RPMS/*/libhsclient*.rpm
+  $ make rpm_perl

+-----------------------------------------------------------------
+To open a connection to the handlersocket plugin, you need to
+create a Net::HandlerSocket object.
+
+  use Net::HandlerSocket;
+  my $args = { host => 'localhost', port => 9998 };
+  my $hs = new Net::HandlerSocket($args);
+
+-----------------------------------------------------------------
+Before executing table operations, you need to open an index to
+work with.
+
+  my $err = $hs->open_index(3, 'database1', 'table1', 'PRIMARY',
+    'f1,f2');
+  die $hs->get_error() if $res->[0] != 0;
+
+The first argument for open_index is an integer value which is
+used to identify an open table, which is only valid within the
+same Net::HandlerSocket object. The 4th argument is the name of
+index to open. If 'PRIMARY' is specified, the primary index is
+open. The 5th argument is a comma-separated list of column names.
+
+-----------------------------------------------------------------
+To read a record from a table using an index, call the
+execute_single method.
+
+  my $res = $hs->execute_single(3, '=', [ 'foo' ], 1, 0);
+  die $hs->get_error() if $res->[0] != 0;
+  shift(@$res);
+
+The first argument must be an integer which has specified as the
+first argument for open_index on the same Net::HandlerSocket
+object. The second argument specifies the search operation. The
+current version of handlersocket supports '=', '>=', '<=', '>',
+and '<'. The 3rd argument specifies the key to find, which must
+an arrayref whose length is equal to or smaller than the number
+of key columns of the index. The 4th and the 5th arguments
+specify the maximum number of records to be retrieved, and the
+number of records skipped before retrieving records. The columns
+to be retrieved are specified by the 5th argument for the
+corresponding open_index call.
+
+The execute_single method always returns an arrayref. The first
+element is the error code, which is 0 when no error is occurred.
+The remaining are the field values. If more than one record is
+returned, it is flatten to an 1-dimensional array. For example,
+when 5 records that have 3 columns are returned, you can retrieve
+values using the following code.
+
+  die $hs->get_error() if $res->[0] != 0;
+  shift(@$res);
+  for (my $row = 0; $row < 5; ++$row) {
+    for (my $col = 0; $col < 3; ++$col) {
+      my $value = $res->[$row * 5 + $col];
+      # ...
+    }
+  }
+
+-----------------------------------------------------------------
+To update or delete records, you need to specify more arguments
+for the execute_single method. Note that the Net::HandlerSocket
+object must be connected to a handlersocket worker for write
+operations, which is port 9999 by default.
+(For safety, the port 9998 only allows read operations, and the
+port 9999 allows write operations also. The port 9999 allows
+read operations too, but slower than 9998 because of record
+locking etc.. Port numbers can be changed using the
+'handlersocket_port' and the 'handlersocket_port_wr'
+configuration options of mysqld.)
+
+  my $args = { host => 'localhost', port => 9999 };
+  my $hs = new Net::HandlerSocket($args);
+
+  my $res = $hs->execute_single(3, '=', [ 'bar' ], 1, 0, 'U',
+    [ 'fubar', 'hoge' ]);
+  die $hs->get_error() if $res->[0] != 0;
+  my $num_updated_rows = $res->[1];
+
+  my $res = $hs->execute_single(3, '=', [ 'baz' ], 1, 0, 'D');
+  die $hs->get_error() if $res->[0] != 0;
+  my $num_deleted_rows = $res->[1];
+
+The 6th argument for execute_single specifies the modification
+operation. The current version supports 'U' and 'D'. For the 'U'
+operation, the 7th argument specifies the new value for the row.
+The columns to be modified are specified by the 5th argument for
+the corresponding open_index call. For the 'D' operation, the
+7th argument can be omitted.
+
+-----------------------------------------------------------------
+The execute_single method can be used for inserting records also.
+
+  my $res = $hs->execute_single(3, '+', [ 'foo', 'bar', 'baz' ]);
+  die $hs->get_error() if $res->[0] != 0;
+
+The 3rd argument must be an arrayref whose elements correspond to
+the 5th argument for the corresponding open_index call. If there
+is a column which is not appeared in the 5th argument for the
+open_index, the default value for the column is set.
+
+-----------------------------------------------------------------
+Multiple operations can be executed in a single call. Executing
+multiple operations in a single call is much faster than
+executing them separatedly. 
+
+  my $rarr = $hs->execute_multi([
+    [ 0, '>=', [ 'foo' ], 5, 0 ],
+    [ 2, '=', [ 'bar' ], 1, 0 ],
+    [ 4, '<', [ 'baz' ], 10, 5 ],
+  ]);
+  for my $res (@$rarr) {
+    die $hs->get_error() if $res->[0] != 0;
+    shift(@$res);
+    # ...
+  }
+
+-----------------------------------------------------------------
+If handlersocket is configured to authenticate client connections
+(ie., handlersocket_plain_secret or handlersocket_plain_secret_wr
+is set), a client must call 'auth' method before any other
+methods.
+
+  my $res = $hs->auth('password');
+  die $hs->get_error() if $res->[0] != 0;
+
+-----------------------------------------------------------------
+When an error is occurred, the first element of the returned
+arrayref becomes a non-zero value. A negative value indicates
+that an I/O error is occurred and the Net::HandlerSocket object
+should be disposed. A positive value means that the connection is
+still active and the Net::HandlerSocket object can be reused
+later.

+----------------------------------------------------------------------------
+The HandlerSocket protocol
+
+----------------------------------------------------------------------------
+Basic syntax
+
+- The HandlerSocket protocol is line-based. Each line ends with LF(0x0a).
+- Each line consists a concatenation of tokens separated by HT(0x09).
+- A token is either NULL or an encoded string. Note that you need to
+  distinguish NULL from an empty string, as most DBMs does so.
+- NULL is expressed as a single NUL(0x00).
+- An encoded string is a string with the following encoding rules.
+  	- Characters in the range [0x10 - 0xff] are encoded as itselves.
+	- A character in the range [0x00 - 0x0f] is prefixed by 0x01 and
+	  shifted by 0x40. For example, 0x03 is encoded as 0x01 0x43.
+- Note that a string can be empty. A continuation of 0x09 0x09 means that
+  there is an empty string between them. A continuation of 0x09 0x0a means
+  that there is an empty string at the end of the line.
+
+----------------------------------------------------------------------------
+Request and Response
+
+- The HandlerSocket protocol is a simple request/response protocol. After a
+  connection is established, the client side sends a request, and then the
+  server side sends a response.
+- A request/response consists of a single line.
+- Requests can be pipelined; That is, you can send multiple requests (ie.
+  lines) at one time, and receive responses for them at one time.
+
+----------------------------------------------------------------------------
+Opening index
+
+The 'open_index' request has the following syntax.
+
+    P <indexid> <dbname> <tablename> <indexname> <columns> [<fcolumns>]
+
+- <indexid> is a number in decimal.
+- <dbname>, <tablename>, and <indexname> are strings. To open the primary
+  key, use PRIMARY as <indexname>.
+- <columns> is a comma-separated list of column names.
+- <fcolumns> is a comma-separated list of column names. This parameter is
+  optional.
+
+Once an 'open_index' request is issued, the HandlerSocket plugin opens the
+specified index and keep it open until the client connection is closed. Each
+open index is identified by <indexid>. If <indexid> is already open, the old
+open index is closed. You can open the same combination of <dbname>
+<tablename> <indexname> multiple times, possibly with different <columns>.
+For efficiency, keep <indexid> small as far as possible.
+
+----------------------------------------------------------------------------
+Getting data
+
+The 'find' request has the following syntax.
+ 
+    <indexid> <op> <vlen> <v1> ... <vn> [LIM] [IN] [FILTER ...]
+
+LIM is a sequence of the following parameters.
+
+    <limit> <offset>
+
+IN is a sequence of the following parameters.
+    
+    @ <icol> <ivlen> <iv1> ... <ivn>
+
+FILETER is a sequence of the following parameters.
+
+    <ftyp> <fop> <fcol> <fval>
+
+- <indexid> is a number. This number must be an <indexid> specified by a
+  'open_index' request executed previously on the same connection.
+- <op> specifies the comparison operation to use. The current version of
+  HandlerSocket supports '=', '>', '>=', '<', and '<='.
+- <vlen> indicates the length of the trailing parameters <v1> ... <vn>. This
+  must be smaller than or equal to the number of index columns specified by
+  the <indexname> parameter of the corresponding 'open_index' request.
+- <v1> ... <vn> specify the index column values to fetch.
+- LIM is optional. <limit> and <offset> are numbers. When omitted, it works
+  as if 1 and 0 are specified. These parameter works like LIMIT of SQL.
+  These values don't include the number of records skipped by a filter.
+- IN is optional. It works like WHERE ... IN syntax of SQL. <icol> must be
+  smaller than the number of index columns specified by the <indexname>
+  parameter of the corresponding 'open_index' request. If IN is specified in
+  a find request, the <icol>-th parameter value of <v1> ...  <vn> is ignored.
+- FILTERs are optional. A FILTER specifies a filter. <ftyp> is either 'F'
+  (filter) or 'W' (while). <fop> specifies the comparison operation to use.
+  <fcol> must be smaller than the number of columns specified by the
+  <fcolumns> parameter of the corresponding 'open_index' request. Multiple
+  filters can be specified, and work as the logical AND of them. The
+  difference of 'F' and 'W' is that, when a record does not meet the
+  specified condition, 'F' simply skips the record, and 'W' stops the loop.
+
+----------------------------------------------------------------------------
+Updating/Deleting data
+
+The 'find_modify' request has the following syntax.
+
+    <indexid> <op> <vlen> <v1> ... <vn> [LIM] [IN] [FILTER ...] MOD
+
+MOD is a sequence of the following parameters.
+
+    <mop> <m1> ... <mk>
+
+- <mop> is 'U' (update), '+' (increment), '-' (decrement), 'D' (delete),
+  'U?', '+?', '-?', or 'D?'. If the '?' suffix is specified, it returns
+  the contents of the records before modification (as if it's a 'find'
+  request), instead of the number of modified records.
+- <m1> ... <mk> specifies the column values to set. The length of <m1> ...
+  <mk> must be smaller than or equal to the length of <columns> specified by
+  the corresponding 'open_index' request. If <mop> is 'D', these parameters
+  are ignored. If <mop> is '+' or '-', values must be numeric. If <mop> is
+  '-' and it attempts to change a column value from negative to positive or
+  positive to negative, the column value is not modified.
+
+----------------------------------------------------------------------------
+Inserting data
+
+The 'insert' request has the following syntax.
+
+    <indexid> + <vlen> <v1> ... <vn>
+
+- <vlen> indicates the length of the trailing parameters <v1> ... <vn>. This
+  must be smaller than or equal to the length of <columns> specified by the
+  corresponding 'open_index' request.
+- <v1> ... <vn> specify the column values to set. For columns not in
+  <columns>, the default values for each column are set.
+
+----------------------------------------------------------------------------
+Authentication
+
+The 'auth' request has the following syntax.
+
+    A <atyp> <akey>
+
+- <atyp> must be '1'
+- An 'auth' request succeeds iff <akey> is the correct secret specified by
+  the 'handlersocket_plain_secret' or 'handlersocket_plain_secret_rw'.
+- If an authentication is enabled for a listener, any other requests on a
+  connection fail before an 'auth' request succeeded on the connection.
+
+----------------------------------------------------------------------------
+Response syntax
+
+HandlerSocket returns a response of the following syntax for each request.
+
+    <errorcode> <numcolumns> <r1> ... <rn>
+
+- <errorcode> indicates whether the request has successfully executed or not.
+  '0' means success. Non-zero means an error.
+- <numcolumns> indicates the number of columns of the result set.
+- <r1> ... <rn> is the result set. The length of <r1> ... <rn> is always a
+  multiple of <numcolumns>. It is possible that <r1> ... <rn> is empty.
+
+If <errorcode> is non-zero, <numcolumns> is always 1 and <r1> indicates a
+human-readable error message, though sometimes <r1> is not provided.
+
+----------------------------------------------------------------------------
+Response for 'open_index'
+
+If 'open_index' is succeeded, HandlerSocket returns a line of the following
+syntax.
+
+    0 1
+
+----------------------------------------------------------------------------
+Response for 'find'
+
+If 'find' is succeeded, HandlerSocket returns a line of the following
+syntax.
+
+   0 <numcolumns> <r1> ... <rn>
+
+- <numcolumns> always equals to the length of <columns> of the corresponding
+  'open_index' request.
+- <r1> ... <rn> is the result set. If N rows are found, the length of <r1>
+  ... <rn> becomes ( <numcolumns> * N ).
+
+----------------------------------------------------------------------------
+Response for 'find_modify'
+
+If 'find_modify' is succeeded, HandlerSocket returns a line of the following
+syntax.
+
+   0 1 <nummod>
+
+- <nummod> is the number of modified rows.
+- As an exception, if the '?' suffix is specified in <mop>, a response has
+  the syntax of a response for 'find' instead.
+
+----------------------------------------------------------------------------
+Response for 'insert'
+
+If 'insert' is succeeded, HanderSocket returns a line of the following
+syntax.
+
+   0 1
+
+----------------------------------------------------------------------------
+Response for 'auth'
+
+If 'auth' is succeeded, HanderSocket returns a line of the following syntax.
+
+   0 1
+

+handlersocket pluginについて
+
+mysqlサーバに常駐し、innodb等のストレージエンジンへの直接のアクセ
+スを提供するプラグインです。handlersocketプラグインは自前のリス
+ナーを持ち、専用のクライアントライブラリ(libhsclient)を使ってそれ
+にアクセスします。
+
+mysqlの標準クライアントライブラリ(libmysql)を使ったアクセスと比べ
+て、以下のような利点があります。
+・接続あたりに消費するリソースが少ないため、同時接続数が事実上無
+  制限。したがって接続数を気にせず持続接続を使えます。
+・高速(単純な参照クエリで3倍〜10倍程度)。
+・通信プロトコルがコンパクト。libmysqlを使うとデータ転送時にレ
+  コード名などが付随するために通信内容が冗長ですが、libhsclientで
+  はデータのみが転送されるため、帯域消費が少なくなります。場合に
+  よっては10倍以上libmysqlのほうが冗長になります。
+
+現在のバージョンでは以下のような処理をサポートしています。
+・指定された索引について、指定された値と完全一致するようなレコー
+  ドを取得。(SELECT ??? FROM tbl WHERE k1 = v1 AND k2 = v2...)。
+  索引を使わない検索はサポートしていません。
+・指定された索引について、指定された値の位置の前後のレコードを取
+  得。(SELECT ??? FROM tbl WHERE k1 >= v1 LIMIT 100)
+・前述のような手段で取得したレコードに対するUPDATEとDELETE
+・レコードのINSERT
+
+以下のような言語をサポートします。
+・C++。libhsclientをリンクします。
+・Perl。Net::HandlerSocketをuseします。
+
+現在のバージョンではGNU/Linuxでのみ動作します。
+
+-----------------------------------------------------------------
+既知の問題
+
+・killでhandlersocketスレッドを殺すと、スレッド数が減ったまま回復
+  しません。

+  my $res = $hs->execute_single(3, '+', [ 'foo', 'bar', 'baz' ]);
+  die $hs->get_error() if $res->[0] != 0;
+
+第3引数は、対応するopen_index呼び出しの第5引数の列リストと同じだ
+けの長さの配列への参照でなければなりません。open_index呼び出しの
+第5引数に指定されていない列については、その列の既定値がセットされ
+ます。
+
+-----------------------------------------------------------------
+execute_multiメソッドを使えば、複数のリクエストを一つの呼び出しで
+実行することができます。これはリクエストを個別に実行するより高速
+です。
+
+  my $rarr = $hs->execute_multi([
+    [ 0, '>=', [ 'foo' ], 5, 0 ],
+    [ 2, '=', [ 'bar' ], 1, 0 ],
+    [ 4, '<', [ 'baz' ], 10, 5 ],
+  ]);
+  for my $res (@$rarr) {
+    die $hs->get_error() if $res->[0] != 0;
+    shift(@$res);
+    # ...
+  }
+
+-----------------------------------------------------------------
+もしhandlersocketが接続を認証するように設定されている
+(handlersocket_plain_secret又はhandlersocket_plain_secret_wrがセッ
+トされている)ならば、クライアントは他のメソッド呼び出しの前にauth
+メソッドを呼び出す必要があります。
+
+  my $res = $hs->auth('password');
+  die $hs->get_error() if $res->[0] != 0;
+
+-----------------------------------------------------------------
+エラーが起こると返値の配列参照の最初の要素が0以外になります。負の
+数の場合はI/Oエラーが起こったことを示し、その場合はその
+Net::HandlerSocketオブジェクトは破棄するべきです。正の値の場合は
+接続は維持されているため、そのオブジェクトはそれ以後も再利用でき
+ます。

+handlersocketの通信プロトコル
+
+----------------------------------------------------------------------------
+基本的な構文
+
+・HandlerSocketのプロトコルは行ベース。各行は改行文字(0x0a)で終わる。
+・各行は複数のトークンからなり、トークン間はTAB文字(0x09)で区切られる。
+・トークンはNULLトークンか、文字列トークンのいずれか。
+・NULLトークンは単一のNUL文字(0x00)であらわされる。
+・文字列トークンは、0バイト以上の文字列であらわされる。ただし0x10未満の文字
+  については0x01を前置し、0x40を加えたコードであらわされる。それ以外の文字は
+  その文字自身のコードであらわされる。
+
+----------------------------------------------------------------------------
+リクエストとレスポンス
+
+・HandlerSocketのプロトコルは単純なリクエスト・レスポンスプロトコルになって
+  いる。接続が確立した後は、まずクライアントがリクエストを送る。
+・サーバは、クライアントが送ったリクエストと丁度同じ数の行(レスポンス)を返
+  す。
+・リクエストはパイプライン化してよい。つまりクライアントは前に送ったリクエス
+  トに対する返事(レスポンス)を待たずに次のリクエストを送ってもよい。
+
+----------------------------------------------------------------------------
+インデックスを開く
+
+open_index命令は次のような構文を持つ。
+
+    P <indexid> <dbname> <tablename> <indexname> <columns> [<fcolumns>]
+
+- <indexid>は数字で、同一接続上で後に実行する命令の、対象索引を指定するため
+  に使われる。
+- <dbname>, <tablename>, <indexname>は文字列で、それぞれDB名、テーブル名、
+  索引の名前を指定する。<indexname>として「PRIMARY」を指定するとプライマリ
+  キーが開かれる。
+- <columns>はカンマ区切りの列名のリスト。
+- <fcolumns>はカンマ区切りの列名のリスト。これは省略することができる。
+
+このopen_index命令が実行されると、HandlerSocketプラグインは指定されたDB、
+テーブル、索引を開く。開かれた索引は接続が閉じられるまで開かれたままになる。
+開かれた索引は<indexid>の数字で識別される。もし既に<indexid>に指定された番号
+の索引が既に開かれている場合は古いほうが閉じられる。この<indexid>はなるべく
+小さな数字を使ったほうが効率が良い。
+
+----------------------------------------------------------------------------
+データ取得
+
+find命令は次のような構文を持つ。
+
+    <indexid> <op> <vlen> <v1> ... <vn> [LIM] [IN] [FILTER ...]
+
+LIMは次のようなパラメータの並び
+
+    <limit> <offset>
+
+INは次のようなパラメータの並び
+
+    @ <icol> <ivlen> <iv1> ... <ivn>
+
+FILTERは次のようなパラメータの並び
+
+    <ftyp> <fop> <fcol> <fval>
+
+- <indexid>は数字で、これは同じ接続上で過去に実行したopen_index命令に指定さ
+  れた数字でなければならない。
+- <op>は比較演算子で、現在のバージョンでは '=', '>', '>=', '<', '<=' をサ
+  ポートしている。
+- <vlen>は後に続くパラメータ<v1> ... <vn>の長さ。この値は対応するopen_index
+  命令の<indexname>パラメータで指定された索引のキー列の数と同じか小さいもの
+  でなければならない。
+- <v1> ... <vn>は取得するべきキーの値を指定するパラメータ。
+- LIMは省略できる。<limit>と<offset>は数字で、これはSQLのLIMITと同じように
+  はたらく。省略した場合は1と0を指定した場合と同じ動作をする。FILTERによっ
+  て読み飛ばされたレコードは<limit>と<offset>にカウントされない。
+- INは省略できる。指定されると、これはSQLの WHERE ... IN のように動作する。
+  <icol>は対応するopen_index命令の<indexname>パラメータで指定された索引の
+  キー列の数より小さいものでなければならない。INが指定されたときは、find命
+  令の<v1> ... <vn>のうち<icol>番目の値は無視される。
+- FILTERは省略できる。これは行取得の際のフィルタを指定する。<ftyp>は
+  'F'(filter)か'W'(while)のいずれかでなければならない。<fop>は比較演算子。
+  <fcol>は数字で、これは対応するopen_index命令の<fcolumns>で指定された列の
+  数より小さいものでなければならない。複数のフィルタを指定することもでき、
+  その場合は各フィルタのANDと解釈される。'F'と'W'の違いは、条件にあてはま
+  らない行があったときに'F'は単にそれをスキップするが、'W'はその時点でルー
+  プを抜けるという点。
+
+----------------------------------------------------------------------------
+更新と削除
+
+find_modify命令は次のような構文を持つ。
+
+    <indexid> <op> <vlen> <v1> ... <vn> [LIM] [IN] [FILTER ...] MOD
+
+MODは次のようなパラメータの並び
+
+    <mop> <m1> ... <mk>
+
+- <mop>は'U', '+', '-', 'D', 'U?', '+?', '-?', 'D?'のいずれか。'?'が付いた
+  ものは付いていないものとほぼ同じ動作をするが、付いていないものがレスポン
+  スとして更新された行の数を返すのに対し、付いているものは更新される前の行
+  の内容を返す点のみが異なる。'U'は更新、'D'は削除、'+'はインクリメント、
+  '-'はデクリメントを実行する。
+- <m1> ... <mk>はセットされる各列の値。<m1> ... <mk>の長さは対応する
+  open_index命令の<columns>の長さと等しいか小さくなければならない。<mop>が
+  'D'のときはこれらのパラメータは無視される。<mop>が'+'か'-'のときは、これら
+  の値は数値でなければならない。<mop>が'-'で、それが負数から正数、または正数
+  から負数へ列の値を変更するようなものであった場合は、値は変更されない。
+
+----------------------------------------------------------------------------
+行の挿入
+
+insert命令は次のような構文を持つ。
+
+    <indexid> + <vlen> <v1> ... <vn>
+
+- <vlen>は後に続くパラメータ<v1> ... <vn>の長さ。これは対応するopen_indexの
+  <columns>の長さに等しいか小さくなければならない。
+- <v1> ... <vn>はセットされる各列の値。指定されないかった列についてはその列
+  のデフォルト値がセットされる。
+
+----------------------------------------------------------------------------
+認証
+
+auth命令は次のような構文を持つ。
+
+    A <atyp> <akey>
+
+- <atyp>は現在のバージョンでは'1'のみが有効。
+- 指定された<akey>が、サーバの設定の'handlersocket_plain_secret'や
+  'handlersocket_plain_secret_wr'に指定された文字列と一致した場合にのみ認証
+  は成功する。
+- HandlerSocketの認証が有効になっているときは、この'auth'が成功しない限りそ
+  れ以外の命令は全て失敗する。
+
+----------------------------------------------------------------------------
+open_indexに対するレスポンス
+
+open_index命令が成功したとき、レスポンスは次の構文を持つ。
+
+    0 1
+
+----------------------------------------------------------------------------
+findに対するレスポンス
+
+find命令が成功したとき、レスポンスは次の構文を持つ。
+
+    0 <numcolumns> <r1> ... <rn>
+
+- <numcolumns>はfind命令の対応するopen_index命令に指定した<columns>の長さに
+  一致する。
+- <r1> ... <rn>は結果セット。もしN行がfind命令で見つかったなら、<r1> ...
+  <rn>の長さは ( <numcolumns> * N )になる。
+
+----------------------------------------------------------------------------
+find_modifyに対するレスポンス
+
+find_modify命令が成功したとき、レスポンスは次の構文を持つ。
+
+    0 1 <nummod>
+
+- <nummod>は変更された行の数。
+- 例外として、<mop>が'?'の付いたものであった場合には、find命令に対するレスポ
+  ンスと同じ構文のレスポンスを返す。
+
+----------------------------------------------------------------------------
+insertに対するレスポンス
+
+insert命令が成功したとき、レスポンスは次の構文を持つ。
+
+    0 1
+
+----------------------------------------------------------------------------
+authに対するレスポンス
+
+auth命令が成功したとき、レスポンスは次の構文を持つ。
+
+    0 1

+HandlerSocket version 0.01
+==========================
+
+The README is used to introduce the module and provide instructions on
+how to install the module, any machine dependencies it may have (for
+example C compilers and installed libraries) and any other information
+that should be provided before the module is installed.
+
+A README file is required for CPAN modules since CPAN extracts the
+README file from a module distribution so that people browsing the
+archive can use it get an idea of the modules uses. It is usually a
+good idea to provide version information here so that people can
+decide whether fixes for the module are worth downloading.
+
+INSTALLATION
+
+To install this module type the following:
+
+   perl Makefile.PL
+   make
+   make test
+   make install

+=head1 COMPATIBILITY
+
+This version of F<ppport.h> is designed to support operation with Perl
+installations back to 5.003, and has been tested up to 5.10.0.
+
+=head1 OPTIONS
+
+=head2 --help
+
+Display a brief usage summary.
+
+=head2 --version
+
+Display the version of F<ppport.h>.
+
+=head2 --patch=I<file>
+
+If this option is given, a single patch file will be created if
+any changes are suggested. This requires a working diff program
+to be installed on your system.
+
+=head2 --copy=I<suffix>
+
+If this option is given, a copy of each file will be saved with
+the given suffix that contains the suggested changes. This does
+not require any external programs. Note that this does not
+automagially add a dot between the original filename and the
+suffix. If you want the dot, you have to include it in the option
+argument.
+
+If neither C<--patch> or C<--copy> are given, the default is to
+simply print the diffs for each file. This requires either
+C<Text::Diff> or a C<diff> program to be installed.
+
+=head2 --diff=I<program>
+
+Manually set the diff program and options to use. The default
+is to use C<Text::Diff>, when installed, and output unified
+context diffs.
+
+=head2 --compat-version=I<version>
+
+Tell F<ppport.h> to check for compatibility with the given
+Perl version. The default is to check for compatibility with Perl
+version 5.003. You can use this option to reduce the output
+of F<ppport.h> if you intend to be backward compatible only
+down to a certain Perl version.
+
+=head2 --cplusplus
+
+Usually, F<ppport.h> will detect C++ style comments and
+replace them with C style comments for portability reasons.
+Using this option instructs F<ppport.h> to leave C++
+comments untouched.
+
+=head2 --quiet
+
+Be quiet. Don't print anything except fatal errors.
+
+=head2 --nodiag
+
+Don't output any diagnostic messages. Only portability
+alerts will be printed.
+
+=head2 --nohints
+
+Don't output any hints. Hints often contain useful portability
+notes. Warnings will still be displayed.
+
+=head2 --nochanges
+
+Don't suggest any changes. Only give diagnostic output and hints
+unless these are also deactivated.
+
+=head2 --nofilter
+
+Don't filter the list of input files. By default, files not looking
+like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped.
+
+=head2 --strip
+
+Strip all script and documentation functionality from F<ppport.h>.
+This reduces the size of F<ppport.h> dramatically and may be useful
+if you want to include F<ppport.h> in smaller modules without
+increasing their distribution size too much.
+
+The stripped F<ppport.h> will have a C<--unstrip> option that allows
+you to undo the stripping, but only if an appropriate C<Devel::PPPort>
+module is installed.
+
+=head2 --list-provided
+
+Lists the API elements for which compatibility is provided by
+F<ppport.h>. Also lists if it must be explicitly requested,
+if it has dependencies, and if there are hints or warnings for it.
+
+=head2 --list-unsupported
+
+Lists the API elements that are known not to be supported by
+F<ppport.h> and below which version of Perl they probably
+won't be available or work.
+
+=head2 --api-info=I<name>
+
+Show portability information for API elements matching I<name>.
+If I<name> is surrounded by slashes, it is interpreted as a regular
+expression.
+
+=head1 DESCRIPTION
+
+In order for a Perl extension (XS) module to be as portable as possible
+across differing versions of Perl itself, certain steps need to be taken.
+
+=over 4
+
+=item *
+
+Including this header is the first major one. This alone will give you
+access to a large part of the Perl API that hasn't been available in
+earlier Perl releases. Use
+
+    perl ppport.h --list-provided
+
+to see which API elements are provided by ppport.h.
+
+=item *
+
+You should avoid using deprecated parts of the API. For example, using
+global Perl variables without the C<PL_> prefix is deprecated. Also,
+some API functions used to have a C<perl_> prefix. Using this form is
+also deprecated. You can safely use the supported API, as F<ppport.h>
+will provide wrappers for older Perl versions.
+
+=item *
+
+If you use one of a few functions or variables that were not present in
+earlier versions of Perl, and that can't be provided using a macro, you
+have to explicitly request support for these functions by adding one or
+more C<#define>s in your source code before the inclusion of F<ppport.h>.
+
+These functions or variables will be marked C<explicit> in the list shown
+by C<--list-provided>.
+
+Depending on whether you module has a single or multiple files that
+use such functions or variables, you want either C<static> or global
+variants.
+
+For a C<static> function or variable (used only in a single source
+file), use:
+
+    #define NEED_function
+    #define NEED_variable
+
+For a global function or variable (used in multiple source files),
+use:
+
+    #define NEED_function_GLOBAL
+    #define NEED_variable_GLOBAL
+
+Note that you mustn't have more than one global request for the
+same function or variable in your project.
+
+    Function / Variable       Static Request               Global Request

+
+To avoid namespace conflicts, you can change the namespace of the
+explicitly exported functions / variables using the C<DPPP_NAMESPACE>
+macro. Just C<#define> the macro before including C<ppport.h>:
+
+    #define DPPP_NAMESPACE MyOwnNamespace_
+    #include "ppport.h"
+
+The default namespace is C<DPPP_>.
+
+=back
+
+The good thing is that most of the above can be checked by running
+F<ppport.h> on your source code. See the next section for
+details.
+
+=head1 EXAMPLES
+
+To verify whether F<ppport.h> is needed for your module, whether you
+should make any changes to your code, and whether any special defines
+should be used, F<ppport.h> can be run as a Perl script to check your
+source code. Simply say:
+
+    perl ppport.h
+
+The result will usually be a list of patches suggesting changes
+that should at least be acceptable, if not necessarily the most
+efficient solution, or a fix for all possible problems.
+
+If you know that your XS module uses features only available in
+newer Perl releases, if you're aware that it uses C++ comments,
+and if you want all suggestions as a single patch file, you could
+use something like this:
+
+    perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff
+
+If you only want your code to be scanned without any suggestions
+for changes, use:
+
+    perl ppport.h --nochanges
+
+You can specify a different C<diff> program or options, using
+the C<--diff> option:
+
+    perl ppport.h --diff='diff -C 10'
+
+This would output context diffs with 10 lines of context.
+
+If you want to create patched copies of your files instead, use:
+
+    perl ppport.h --copy=.new
+
+To display portability information for the C<newSVpvn> function,
+use:
+
+    perl ppport.h --api-info=newSVpvn
+
+Since the argument to C<--api-info> can be a regular expression,
+you can use
+
+    perl ppport.h --api-info=/_nomg$/
+
+to display portability information for all C<_nomg> functions or
+
+    perl ppport.h --api-info=/./
+
+to display information for all known API elements.
+
+=head1 BUGS
+
+If this version of F<ppport.h> is causing failure during
+the compilation of this module, please check if newer versions
+of either this module or C<Devel::PPPort> are available on CPAN
+before sending a bug report.
+
+If F<ppport.h> was generated using the latest version of
+C<Devel::PPPort> and is causing failure of this module, please
+file a bug report using the CPAN Request Tracker at L<http://rt.cpan.org/>.
+
+Please include the following information:
+
+=over 4
+
+=item 1.
+
+The complete output from running "perl -V"
