For + example, a DECIMAL(20,10) column has ten digits on either side of + the decimal separator. + + The characteristic that needs to be taken into account is that the + backing type for Item_decimal is a my_decimal that has a higher + precision (DECIMAL_MAX_POSSIBLE_PRECISION, see my_decimal.h) than + DECIMAL. + + Drawing a comparison between my_decimal and DECIMAL: + + * M has a range of 1 to 81. + * D has a range of 0 to 81. + + There can be a difference in range if the decimal contains a integer + part.

Since each + group is 9 (DIG_PER_DEC1) digits and there are 9 (DECIMAL_BUFF_LENGTH) + groups, the fractional part is limited to 72 digits if there is at + least one digit in the integral part. + + Although the backing type for a DECIMAL is also my_decimal, every + time a my_decimal is stored in a DECIMAL field, the precision and + scale are explicitly capped at 65 (DECIMAL_MAX_PRECISION) and 30 + (DECIMAL_MAX_SCALE) digits, following my_decimal truncation procedure + (FIX_INTG_FRAC_ERROR). +*/ + +Field_new_decimal * +Field_new_decimal::new_decimal_field(const Item *item) +{ + uint32 len;

It is a storage engine that +uses a client connection to a remote MySQL data source as its data +source instead of a local file on disk. + +Q. Why did you fork from Federated? + +A. To enhance the storage engine independently of the +MySQL Server release schedule. Many people have been +mentioning their dissatisfaction with the limitations +of Federated.

Many things need addressing: + +- Outstanding bugs +- How do deal with huge result sets +- Pushdown conditions (being able to pass things like LIMIT + to the remote connection to keep from returning huge + result sets). +- Better transactional support +- Other connection mechanisms (ODBC, JDBC, native drivers + of other RDBMSs) + +Q.

A handler reads, inserts, + deletes, updates data in this file. The data is stored in particular format, + so to read, that data has to be parsed into fields, to write, fields have to + be stored in this format to write to this data file. + + With FederatedX storage engine, there will be no local files + for each table's data (such as .MYD). A foreign database will store + the data that would normally be in this file. This will necessitate + the use of MySQL client API to read, delete, update, insert this + data. The data will have to be retrieve via an SQL call "SELECT * + FROM users". Then, to read this data, it will have to be retrieved + via mysql_fetch_row one row at a time, then converted from the + column in this select into the format that the handler expects. + + The create table will simply create the .frm file, and within the + "CREATE TABLE" SQL, there SHALL be any of the following : + + connection=scheme://username:password@hostname:port/database/tablename + connection=scheme://username@hostname/database/tablename + connection=scheme://username:password@hostname/database/tablename + connection=scheme://username:password@hostname/database/tablename + + - OR - + + As of 5.1 federatedx now allows you to use a non-url + format, taking advantage of mysql.servers: + + connection="connection_one" + connection="connection_one/table_foo" + + An example would be: + + connection=mysql://username:password@hostname:port/database/tablename + + or, if we had: + + create server 'server_one' foreign data wrapper 'mysql' options + (HOST '127.0.0.1', + DATABASE 'db1', + USER 'root', + PASSWORD '', + PORT 3306, + SOCKET '', + OWNER 'root'); + + CREATE TABLE federatedx.t1 ( + `id` int(20) NOT NULL, + `name` varchar(64) NOT NULL default '' + ) + ENGINE="FEDERATEDX" DEFAULT CHARSET=latin1 + CONNECTION='server_one'; + + So, this will have been the equivalent of + + CONNECTION="mysql://root@127.0.0.1:3306/db1/t1" + + Then, we can also change the server to point to a new schema: + + ALTER SERVER 'server_one' options(DATABASE 'db2'); + + All subsequent calls will now be against db2.t1! Guess what? You don't + have to perform an alter table! + + This connecton="connection string" is necessary for the handler to be + able to connect to the foreign server, either by URL, or by server + name. + + + The basic flow is this: + + SQL calls issues locally -> + mysql handler API (data in handler format) -> + mysql client API (data converted to SQL calls) -> + foreign database -> mysql client API -> + convert result sets (if any) to handler format -> + handler API -> results or rows affected to local + + What this handler does and doesn't support + ------------------------------------------ + * Tables MUST be created on the foreign server prior to any action on those + tables via the handler, first version. IMPORTANT: IF you MUST use the + federatedx storage engine type on the REMOTE end, MAKE SURE [ :) ] That + the table you connect to IS NOT a table pointing BACK to your ORIGNAL + table! You know and have heard the screaching of audio feedback? You + know putting two mirror in front of each other how the reflection + continues for eternity? Well, need I say more?! + * There will not be support for transactions. + * There is no way for the handler to know if the foreign database or table + has changed. The reason for this is that this database has to work like a + data file that would never be written to by anything other than the + database. The integrity of the data in the local table could be breached + if there was any change to the foreign database. + * Support for SELECT, INSERT, UPDATE , DELETE, indexes. + * No ALTER TABLE, DROP TABLE or any other Data Definition Language calls. + * Prepared statements will not be used in the first implementation, it + remains to to be seen whether the limited subset of the client API for the + server supports this. + * This uses SELECT, INSERT, UPDATE, DELETE and not HANDLER for its + implementation. + * This will not work with the query cache. + + Method calls + + A two column table, with one record: + + (SELECT) + + "SELECT * FROM foo" + ha_federatedx::info + ha_federatedx::scan_time: + ha_federatedx::rnd_init: share->select_query SELECT * FROM foo + ha_federatedx::extra + + <for every row of data retrieved> + ha_federatedx::rnd_next + ha_federatedx::convert_row_to_internal_format + ha_federatedx::rnd_next + </for every row of data retrieved> + + ha_federatedx::rnd_end + ha_federatedx::extra + ha_federatedx::reset + + (INSERT) + + "INSERT INTO foo (id, ts) VALUES (2, now());" + + ha_federatedx::write_row + + ha_federatedx::reset + + (UPDATE) + + "UPDATE foo SET ts = now() WHERE id = 1;" + + ha_federatedx::index_init + ha_federatedx::index_read + ha_federatedx::index_read_idx + ha_federatedx::rnd_next + ha_federatedx::convert_row_to_internal_format + ha_federatedx::update_row + + ha_federatedx::extra + ha_federatedx::extra + ha_federatedx::extra + ha_federatedx::external_lock + ha_federatedx::reset + + + How do I use this handler? + -------------------------- + + <insert text about plugin storage engine> + + Next, to use this handler, it's very simple. You must + have two databases running, either both on the same host, or + on different hosts. + + One the server that will be connecting to the foreign + host (client), you create your table as such: + + CREATE TABLE test_table ( + id int(20) NOT NULL auto_increment, + name varchar(32) NOT NULL default '', + other int(20) NOT NULL default '0', + PRIMARY KEY (id), + KEY name (name), + KEY other_key (other)) + ENGINE="FEDERATEDX" + DEFAULT CHARSET=latin1 + CONNECTION='mysql://root@127.0.0.1:9306/federatedx/test_federatedx'; + + Notice the "COMMENT" and "ENGINE" field? This is where you + respectively set the engine type, "FEDERATEDX" and foreign + host information, this being the database your 'client' database + will connect to and use as the "data file". Obviously, the foreign + database is running on port 9306, so you want to start up your other + database so that it is indeed on port 9306, and your federatedx + database on a port other than that. In my setup, I use port 5554 + for federatedx, and port 5555 for the foreign database. + + Then, on the foreign database: + + CREATE TABLE test_table ( + id int(20) NOT NULL auto_increment, + name varchar(32) NOT NULL default '', + other int(20) NOT NULL default '0', + PRIMARY KEY (id), + KEY name (name), + KEY other_key (other)) + ENGINE="<NAME>" <-- whatever you want, or not specify + DEFAULT CHARSET=latin1 ; + + This table is exactly the same (and must be exactly the same), + except that it is not using the federatedx handler and does + not need the URL. + + + How to see the handler in action + -------------------------------- + + When developing this handler, I compiled the federatedx database with + debugging: + + ./configure --with-federatedx-storage-engine + --prefix=/home/mysql/mysql-build/federatedx/ --with-debug + + Once compiled, I did a 'make install' (not for the purpose of installing + the binary, but to install all the files the binary expects to see in the + diretory I specified in the build with --prefix, + "/home/mysql/mysql-build/federatedx". + + Then, I started the foreign server: + + /usr/local/mysql/bin/mysqld_safe + --user=mysql --log=/tmp/mysqld.5555.log -P 5555 + + Then, I went back to the directory containing the newly compiled mysqld, + <builddir>/sql/, started up gdb: + + gdb ./mysqld + + Then, withn the (gdb) prompt: + (gdb) run --gdb --port=5554 --socket=/tmp/mysqld.5554 --skip-innodb --debug + + Next, I open several windows for each: + + 1. Tail the debug trace: tail -f /tmp/mysqld.trace|grep ha_fed + 2. Tail the SQL calls to the foreign database: tail -f /tmp/mysqld.5555.log + 3. A window with a client open to the federatedx server on port 5554 + 4. A window with a client open to the federatedx server on port 5555 + + I would create a table on the client to the foreign server on port + 5555, and then to the federatedx server on port 5554. At this point, + I would run whatever queries I wanted to on the federatedx server, + just always remembering that whatever changes I wanted to make on + the table, or if I created new tables, that I would have to do that + on the foreign server. + + Another thing to look for is 'show variables' to show you that you have + support for federatedx handler support: + + show variables like '%federat%' + + and: + + show storage engines; + + Both should display the federatedx storage handler. + + + Testing + ------- + + Testing for FederatedX as a pluggable storage engine for + now is a manual process that I intend to build a test + suite that works for all pluggable storage engines. + + How to test + + 1. cp fed.dat /tmp + (make sure you have access to "test". Use a user that has + super privileges for now) + 2. mysql -f -u root test < federated.test > federated.myresult 2>&1 + 3. diff federated.result federated.myresult (there _should_ be no differences) + + +*/ + + +#define MYSQL_SERVER 1q +#include "mysql_priv.h" +#include <mysql/plugin.h> + +#ifdef USE_PRAGMA_IMPLEMENTATION +#pragma implementation // gcc: Class implementation +#endif + +#include "ha_federatedx.h" + +#include "m_string.h" + +#include <mysql/plugin.h> + +/* Variables for federatedx share methods */ +static HASH federatedx_open_tables;
