A --engine=<storage_engine>:<option> was not always properly parsed and in some cases crashed. Fixed by eliminating "set storage_engine = ..." and adding proper DDL generation. Initialized an unitialized buffer to prevent crashes and fixed to use proper pointer for in case of --engine=<storage_engine>:<option> being the last element in list of --engines. Also cleaned up code for better readability. Q: Should MySQL's replication actually replicate a "set storage_engine = ..." command or not? A: No it should not. It is documented here: http://dev.mysql.com/doc/refman/5.1/en/replication-features-variables.html ...

This is a very convenient way to\nget backups if you have a file system such as Veritas that can take\nsnapshots in time.)\n\nThe following discussion applies only to non-TEMPORARY tables. LOCK\nTABLES is allowed (but ignored) for a TEMPORARY table. The table can be\naccessed freely by the session within which it was created, regardless\nof what other locking may be in effect. No lock is necessary because no\nother session can see the table.\n\nThe following general rules apply to acquisition and release of locks\nby a given thread:\n\no Table locks are acquired with LOCK TABLES.\n\no If the LOCK TABLES statement must wait due to locks held by other\n threads on any of the tables, it blocks until all locks can be\n acquired.\n\no Table locks are released explicitly with UNLOCK TABLES.\n\no Table locks are released implicitly under these conditions:\n\n o LOCK TABLES releases any table locks currently held by the thread\n before acquiring new locks.\n\n o Beginning a transaction (for example, with START TRANSACTION)\n implicitly performs an UNLOCK TABLES. (Additional information about\n the interaction between table locking and transactions is given\n later in this section.)\n\n o If a client connection drops, the server releases table locks held\n by the client. If the client reconnects, the locks will no longer\n be in effect. In addition, if the client had an active transaction,\n the server rolls back the transaction upon disconnect, and if\n reconnect occurs, the new session begins with autocommit enabled.\n For this reason, clients may wish to disable auto-reconnect. With\n auto-reconnect in effect, the client is not notified if reconnect\n occurs but any table locks or current transaction will have been\n lost. With auto-reconnect disabled, if the connection drops, an\n error occurs for the next statement issued. The client can detect\n the error and take appropriate action such as reacquiring the locks\n or redoing the transaction. See\n http://dev.mysql.com/doc/refman/5.1/en/auto-reconnect.html.\n\n*Note*: If you use ALTER TABLE on a locked table, it may become\nunlocked. See\nhttp://dev.mysql.com/doc/refman/5.1/en/alter-table-problems.html.\n\nA table lock protects only against inappropriate reads or writes by\nother clients.

For\n more information, see\n http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html.\n\no A natural language search interprets the search string as a phrase in\n natural human language (a phrase in free text).

Full-text searches are natural language searches if the IN\n NATURAL LANGUAGE MODE modifier is given or if no modifier is given.\n\no A query expansion search is a modification of a natural language\n search. The search string is used to perform a natural language\n search. Then words from the most relevant rows returned by the search\n are added to the search string and the search is done again.

MASTER_SSL_VERIFY_SERVER_CERT was\nadded in MySQL 5.1.18. It is used as described for the\n--ssl-verify-server-cert option in\nhttp://dev.mysql.com/doc/refman/5.1/en/ssl-options.html.\n\nMASTER_CONN… specifies how many seconds to wait between connect\nretries. The default is 60. The number of reconnection attempts is\nlimited by the --master-retry-count server option; for more\ninformation, see\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-options.html.\n\nThe SSL options (MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH,\nMASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER), and\nMASTER_SSL_VERIFY_SERVER_CERT can be changed even on slaves that are\ncompiled without SSL support. They are saved to the master.info file,\nbut are ignored unless you use a server that has SSL support enabled.\n\nIf you don\'t specify a given parameter, it keeps its old value, except\nas indicated in the following discussion. For example, if the password\nto connect to your MySQL master has changed, you just need to issue\nthese statements to tell the slave about the new password:\n\nSTOP SLAVE; -- if replication was running\nCHANGE MASTER TO MASTER_PASSWORD=\'new3cret\';\nSTART SLAVE; -- if you want to restart replication\n\nThere is no need to specify the parameters that do not change (host,\nport, user, and so forth).\n\nMASTER_HOST and MASTER_PORT are the host name (or IP address) of the\nmaster host and its TCP/IP port.\n\nThe next two options are available only in MySQL Cluster NDB 6.3 and\n6.4; they are not supported in mainline MySQL 5.1:\n\no MASTER_BIND is for use on replication slaves having multiple network\n interfaces, and determines which of the slave\'s network interfaces is\n chosen for connecting to the master. It is also possible to determine\n which network interface is to be used in such cases by starting the\n slave mysqld process with the --master-bind option.\n\n The ability to bind a replication slave to specific network interface\n was added in MySQL Cluster NDB 6.3.4.\n\no MASTER_HEARTBEAT_PERIOD is used to set the interval in seconds\n between replication heartbeats. Whenever the master\'s binlog is\n updated with an event, the waiting period for the next heartbeat is\n reset. interval is a decimal value having the range 0 to 4294967\n seconds and a resolution to hundredths of a second; the smallest\n nonzero value is 0.001. Heartbeats are sent by the master only if\n there are no unsent events in the binlog file for a period longer\n than interval.\n\n Setting interval to 0 disables heartbeats altogether. The default\n value for interval is equal to the value of slave_net_timeout divided\n by 2.\n\n *Note*: Setting @@global.slave_net_timeout to a value less than that\n of the current heartbeat interval results in a warning being issued.\n\n Issuing RESET SLAVE resets the heartbeat interval to the default.\n\n MASTER_HEARTBEAT_PERIOD was added in MySQL Cluster NDB 6.3.4.\n\n*Note*: Replication cannot use Unix socket files. You must be able to\nconnect to the master MySQL server using TCP/IP.\n\nIf you specify MASTER_HOST or MASTER_PORT, the slave assumes that the\nmaster server is different from before (even if you specify a host or\nport value that is the same as the current value.) In this case, the\nold values for the master binary log name and position are considered\nno longer applicable, so if you do not specify MASTER_LOG_FILE and\nMASTER_LOG_POS in the statement, MASTER_LOG_FILE=\'\' and\nMASTER_LOG_POS=4 are silently appended to it.\n\nSetting MASTER_HOST=\'\' --- that is, setting its value explicitly to an\nempty string --- is not the same as not setting it at all. Setting this\noption to an empty string causes START SLAVE subsequently to fail. This\nissue is addressed in MySQL 6.0. (Bug#28796\n(http://bugs.mysql.com/28796))\n\nMASTER_LOG_FILE and MASTER_LOG_POS are the coordinates at which the\nslave I/O thread should begin reading from the master the next time the\nthread starts. If you specify either of them, you cannot specify\nRELAY_LOG_FILE or RELAY_LOG_POS. If neither of MASTER_LOG_FILE or\nMASTER_LOG_POS are specified, the slave uses the last coordinates of\nthe slave SQL thread before CHANGE MASTER TO was issued. This ensures\nthat there is no discontinuity in replication, even if the slave SQL\nthread was late compared to the slave I/O thread, when you merely want\nto change, say, the password to use.\n\nCHANGE MASTER TO deletes all relay log files and starts a new one,\nunless you specify RELAY_LOG_FILE or RELAY_LOG_POS. In that case, relay\nlogs are kept; the relay_log_purge global variable is set silently to\n0.\n\nCHANGE MASTER TO is useful for setting up a slave when you have the\nsnapshot of the master and have recorded the log and the offset\ncorresponding to it. After loading the snapshot into the slave, you can\nrun CHANGE MASTER TO MASTER_LOG_FILE=\'log_name_on_master\',\nMASTER_LOG_POS=log_offset_on_master on the slave.\n\nThe following example changes the master and master\'s binary log\ncoordinates. This is used when you want to set up the slave to\nreplicate the master:\n\nCHANGE MASTER TO\n MASTER_HOST=\'master2.mycompany.com\',\n MASTER_USER=\'replication\',\n MASTER_PASSWORD=\'bigs3cret\',\n MASTER_PORT=3306,\n MASTER_LOG_FILE=\'master2-bin.001\',\n MASTER_LOG_POS=4,\n MASTER_CONNECT_RETRY=10;\n\nThe next example shows an operation that is less frequently employed.\nIt is used when the slave has relay logs that you want it to execute\nagain for some reason. To do this, the master need not be reachable.\nYou need only use CHANGE MASTER TO and start the SQL thread (START\nSLAVE SQL_THREAD):\n\nCHANGE MASTER TO\n RELAY_LOG_FILE=\'slave-relay-bin.006\',\n RELAY_LOG_POS=4025;\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (184,37,'DROP DATABASE','Syntax:\nDROP {DATABASE | SCHEMA} [IF EXISTS] db_name\n\nDROP DATABASE drops all tables in the database and deletes the\ndatabase.

For rules covering the naming\nof tablespaces, see\nhttp://dev.mysql.com/doc/refman/5.1/en/identifiers.html.\n\n*Note*: All MySQL Cluster Disk Data objects share the same namespace.\nThis means that each Disk Data object must be uniquely named (and not\nmerely each Disk Data object of a given type). For example, you cannot\nhave a tablespace and a log file group with the same name, or a\ntablespace and a data file with the same name.\n\nPrior to MySQL Cluster NDB 6.2.17, 6.3.23, and 6.4.3, path and file\nnames for data files could not be longer than 128 characters.\n(Bug#31770 (http://bugs.mysql.com/31770))\n\nA log file group of one or more UNDO log files must be assigned to the\ntablespace to be created with the USE LOGFILE GROUP clause.\nlogfile_group must be an existing log file group created with CREATE\nLOGFILE GROUP (see\nhttp://dev.mysql.com/doc/refman/5.1/en/create-logfile-group.html).\nMu… tablespaces may use the same log file group for UNDO logging.\n\nThe EXTENT_SIZE sets the size, in bytes, of the extents used by any\nfiles belonging to the tablespace. The default value is 1M. The minimum\nsize is 32K, and theoretical maximum is 2G, although the practical\nmaximum size depends on a number of factors. In most cases, changing\nthe extent size does not have any measurable effect on performance, and\nthe default value is recommended for all but the most unusual\nsituations.\n\nAn extent is a unit of disk space allocation. One extent is filled with\nas much data as that extent can contain before another extent is used.\nIn theory, up to 65,535 (64K) extents may used per data file; however,\nthe recommended maximum is 32,768 (32K). The recommended maximum size\nfor a single data file is 32G --- that is, 32K extents x 1 MB per\nextent. In addition, once an extent is allocated to a given partition,\nit cannot be used to store data from a different partition; an extent\ncannot store data from more than one partition. This means, for example\nthat a tablespace having a single datafile whose INITIAL_SIZE is 256 MB\nand whose EXTENT_SIZE is 128M has just two extents, and so can be used\nto store data from at most two different disk data table partitions.\n\nYou can see how many extents remain free in a given data file by\nquerying the INFORMATION_SCHEMA.FILES table, and so derive an estimate\nfor how much space remains free in the file. For further discussion and\nexamples, see http://dev.mysql.com/doc/refman/5.1/en/files-table.html.\n\nThe INITIAL_SIZE parameter sets the data file\'s total size in bytes.\nOnce the file has been created, its size cannot be changed; however,\nyou can add more data files to the tablespace using ALTER TABLESPACE\n... ADD DATAFILE. See [HELP ALTER TABLESPACE].\n\nINITIAL_SIZE is optional; its default value is 128M.\n\nOn 32-bit systems, the maximum supported value for INITIAL_SIZE is 4G.\n(Bug#29186 (http://bugs.mysql.com/29186))\n\nWhen setting EXTENT_SIZE or INITIAL_SIZE (either or both), you may\noptionally follow the number with a one-letter abbreviation for an\norder of magnitude, similar to those used in my.cnf. Generally, this is\none of the letters M (for megabytes) or G (for gigabytes).\n\nAUTOEXTEND_SIZE, MAX_SIZE, NODEGROUP, WAIT, and COMMENT are parsed but\nignored, and so have no effect in MySQL 5.1. These options are intended\nfor future expansion.\n\nThe ENGINE parameter determines the storage engine which uses this\ntablespace, with engine_name being the name of the storage engine. In\nMySQL 5.1, engine_name must be one of the values NDB or NDBCLUSTER.\n\nWhen CREATE TABLESPACE is used with ENGINE = NDB, a tablespace and\nassociated data file are created on each Cluster data node. You can\nverify that the data files were created and obtain information about\nthem by querying the INFORMATION_SCHEMA.FILES table. For example:\n\nmysql> SELECT LOGFILE_GROUP_NAME, FILE_NAME, EXTRA \n -> FROM INFORMATION_SCHEMA.FILES\n -> WHERE TABLESPACE_NAME = \'newts\' AND FILE_TYPE = \'DATAFILE\';\n+--------------------+-------------+----------------+\n| LOGFILE_GROUP_NAME | FILE_NAME | EXTRA |\n+--------------------+-------------+----------------+\n| lg_3 | newdata.dat | CLUSTER_NODE=3 |\n| lg_3 | newdata.dat | CLUSTER_NODE=4 |\n+--------------------+-------------+----------------+\n2 rows in set (0.01 sec)\n\n(See http://dev.mysql.com/doc/refman/5.1/en/files-table.html.)\n\nCREATE TABLESPACE was added in MySQL 5.1.6.

By default, a routine is\nassociated with the default database. To associate the routine\nexplicitly with a given database, specify the name as db_name.sp_name\nwhen you create it.\n\nThe CREATE FUNCTION statement is also used in MySQL to support UDFs\n(user-defined functions). See\nhttp://dev.mysql.com/doc/refman/5.1/en/adding-functions.html. A UDF can\nbe regarded as an external stored function. However, do note that\nstored functions share their namespace with UDFs. See\nhttp://dev.mysql.com/doc/refman/5.1/en/function-resolution.html, for\nthe rules describing how the server interprets references to different\nkinds of functions.\n\nWhen the routine is invoked, an implicit USE db_name is performed (and\nundone when the routine terminates). The causes the routine to have the\ngiven default database while it executes. USE statements within stored\nroutines are disallowed.\n\nWhen a stored function has been created, you invoke it by referring to\nit in an expression. The function returns a value during expression\nevaluation. When a stored procedure has been created, you invoke it by\nusing the CALL statement (see [HELP CALL]).\n\nTo execute the CREATE PROCEDURE or CREATE FUNCTION statement, it is\nnecessary to have the CREATE ROUTINE privilege. By default, MySQL\nautomatically grants the ALTER ROUTINE and EXECUTE privileges to the\nroutine creator. See also\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.htm… binary logging is enabled, the CREATE FUNCTION statement might also\nrequire the SUPER privilege, as described in\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-logging.html.\n\… DEFINER and SQL SECURITY clauses specify the security context to be\nused when checking access privileges at routine execution time, as\ndescribed later.\n\nIf the routine name is the same as the name of a built-in SQL function,\nyou must use a space between the name and the following parenthesis\nwhen defining the routine, or a syntax error occurs. This is also true\nwhen you invoke the routine later. For this reason, we suggest that it\nis better to avoid re-using the names of existing SQL functions for\nyour own stored routines.\n\nThe IGNORE_SPACE SQL mode applies to built-in functions, not to stored\nroutines. It is always allowable to have spaces after a routine name,\nregardless of whether IGNORE_SPACE is enabled.\n\nThe parameter list enclosed within parentheses must always be present.\nIf there are no parameters, an empty parameter list of () should be\nused. Parameter names are not case sensitive.\n\nEach parameter can be declared to use any valid data type, except that\nthe COLLATE attribute cannot be used.\n\nEach parameter is an IN parameter by default. To specify otherwise for\na parameter, use the keyword OUT or INOUT before the parameter name.\n\n*Note*: Specifying a parameter as IN, OUT, or INOUT is valid only for a\nPROCEDURE. (FUNCTION parameters are always regarded as IN parameters.)\n\nAn IN parameter passes a value into a procedure. The procedure might\nmodify the value, but the modification is not visible to the caller\nwhen the procedure returns. An OUT parameter passes a value from the\nprocedure back to the caller. Its initial value is NULL within the\nprocedure, and its value is visible to the caller when the procedure\nreturns. An INOUT parameter is initialized by the caller, can be\nmodified by the procedure, and any change made by the procedure is\nvisible to the caller when the procedure returns.\n\nFor each OUT or INOUT parameter, pass a user-defined variable in the\nCALL statement that invokes the procedure so that you can obtain its\nvalue when the procedure returns. If you are calling the procedure from\nwithin another stored procedure or function, you can also pass a\nroutine parameter or local routine variable as an IN or INOUT\nparameter.\n\nThe RETURNS clause may be specified only for a FUNCTION, for which it\nis mandatory. It indicates the return type of the function, and the\nfunction body must contain a RETURN value statement. If the RETURN\nstatement returns a value of a different type, the value is coerced to\nthe proper type. For example, if a function specifies an ENUM or SET\nvalue in the RETURNS clause, but the RETURN statement returns an\ninteger, the value returned from the function is the string for the\ncorresponding ENUM member of set of SET members.\n\nThe routine_body consists of a valid SQL procedure statement. This can\nbe a simple statement such as SELECT or INSERT, or it can be a compound\nstatement written using BEGIN and END. Compound statements can contain\ndeclarations, loops, and other control structure statements. The syntax\nfor these statements is described in\nhttp://dev.mysql.com/doc/refman/5.1/en/sql-syntax-compound-statements.h… allows routines to contain DDL statements, such as CREATE and\nDROP. MySQL also allows stored procedures (but not stored functions) to\ncontain SQL transaction statements such as COMMIT. Stored functions may\nnot contain statements that perform explicit or implicit commit or\nrollback. Support for these statements is not required by the SQL\nstandard, which states that each DBMS vendor may decide whether to\nallow them.\n\nStatements that return a result set cannot be used within a stored\nfunction. This includes SELECT statements that do not have an INTO\nvar_list clause and other statements such as SHOW, EXPLAIN, and CHECK\nTABLE. For statements that can be determined at function definition\ntime to return a result set, a Not allowed to return a result set from\na function error occurs (ER_SP_NO_RETSET). For statements that can be\ndetermined only at runtime to return a result set, a PROCEDURE %s can\'t\nreturn a result set in the given context error occurs\n(ER_SP_BADSELECT).\n\nFor additional information about statements that are not allowed in\nstored routines, see\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-program-restrictions.htm… following example shows a simple stored procedure that uses an OUT\nparameter:\n\nmysql> delimiter //\n\nmysql> CREATE PROCEDURE simpleproc (OUT param1 INT)\n -> BEGIN\n -> SELECT COUNT(*) INTO param1 FROM t;\n -> END;\n -> //\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> delimiter ;\n\nmysql> CALL simpleproc(@a);\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT @a;\n+------+\n| @a |\n+------+\n| 3 |\n+------+\n1 row in set (0.00 sec)\n\nThe example uses the mysql client delimiter command to change the\nstatement delimiter from ; to // while the procedure is being defined.\nThis allows the ; delimiter used in the procedure body to be passed\nthrough to the server rather than being interpreted by mysql itself.\nSee\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-defini… information about invoking stored procedures from within programs\nwritten in a language that has a MySQL interface, see [HELP CALL].\n\nThe following example function takes a parameter, performs an operation\nusing an SQL function, and returns the result. In this case, it is\nunnecessary to use delimiter because the function definition contains\nno internal ; statement delimiters:\n\nmysql> CREATE FUNCTION hello (s CHAR(20))\nmysql> RETURNS CHAR(50) DETERMINISTIC\n -> RETURN CONCAT(\'Hello, \',s,\'!\');\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT hello(\'world\');\n+----------------+\n| hello(\'world\') |\n+----------------+\n| Hello, world! |\n+----------------+\n1 row in set (0.00 sec)\n\nMySQL stores the sql_mode system variable setting that is in effect at\nthe time a routine is created, and always executes the routine with\nthis setting in force, regardless of the server SQL mode in effect when\nthe routine is invoked.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (299,20,'VARBINARY','VARBINARY(M)\n\nThe VARBINARY type is similar to the VARCHAR type, but stores binary\nbyte strings rather than non-binary character strings.

Logically, this is\nequivalent to a DELETE statement that deletes all rows, but there are\npractical differences under some circumstances.\n\nFor an InnoDB table, InnoDB processes TRUNCATE TABLE by deleting rows\none by one if there are any FOREIGN KEY constraints that reference the\ntable. If there are no FOREIGN KEY constraints, InnoDB performs fast\ntruncation by dropping the original table and creating an empty one\nwith the same definition, which is much faster than deleting rows one\nby one. The AUTO_INCREMENT counter is reset by TRUNCATE TABLE,\nregardless of whether there is a FOREIGN KEY constraint.\n\nIn the case that FOREIGN KEY constraints reference the table, InnoDB\ndeletes rows one by one and processes the constraints on each one. If\nthe FOREIGN KEY constraint specifies DELETE CASCADE, rows from the\nchild (referenced) table are deleted, and the truncated table becomes\nempty. If the FOREIGN KEY constraint does not specify CASCADE, the\nTRUNCATE statement deletes rows one by one and stops if it encounters a\nparent row that is referenced by the child, returning this error:\n\nERROR 1451 (23000): Cannot delete or update a parent row: a foreign\nkey constraint fails (`test`.`child`, CONSTRAINT `child_ibfk_1`\nFOREIGN KEY (`parent_id`) REFERENCES `parent` (`id`))\n\nThis is the same as a DELETE statement with no WHERE clause.\n\nBeginning with MySQL 5.1.32, TRUNCATE is treated for purposes of binary\nlogging and replication as DROP TABLE followed by CREATE TABLE --- that\nis, as DDL rather than DML. This is due to the fact that, when using\nInnoDB and other transactional storage engines where the transaction\nisolation level does not allow for statement-based logging (READ\nCOMMITTED or READ UNCOMMITTED), the statement was not logged and\nreplicated when using STATEMENT or MIXED logging mode. (Bug#36763\n(http://bugs.mysql.com/36763)) However, it is still applied on\nreplication slaves using InnoDB in the manner described previously.\n\nThe count of rows affected by TRUNCATE TABLE is accurate only when it\nis mapped to a DELETE statement.\n\nFor other storage engines, TRUNCATE TABLE differs from DELETE in the\nfollowing ways in MySQL 5.1:\n\no Truncate operations drop and re-create the table, which is much\n faster than deleting rows one by one, particularly for large tables.\n\no Truncate operations are not transaction-safe; an error occurs when\n attempting one in the course of an active transaction or active table\n lock.\n\no Truncation operations do not return the number of deleted rows.\n\no As long as the table format file tbl_name.frm is valid, the table can\n be re-created as an empty table with TRUNCATE TABLE, even if the data\n or index files have become corrupted.\n\no The table handler does not remember the last used AUTO_INCREMENT\n value, but starts counting from the beginning. This is true even for\n MyISAM and InnoDB, which normally do not reuse sequence values.\n\no When used with partitioned tables, TRUNCATE TABLE preserves the\n partitioning; that is, the data and index files are dropped and\n re-created, while the partition definitions (.par) file is\n unaffected.\n\no Since truncation of a table does not make any use of DELETE, the\n TRUNCATE statement does not invoke ON DELETE triggers.\n\nTRUNCATE TABLE requires the DROP privilege as of MySQL 5.1.16.

(spin_rounds\n divided by spin_waits provides the average round count.)\n\n o os_waits indicates the number of operating system waits. This\n occurs when the spinlock did not work (the mutex was not locked\n during the spinlock and it was necessary to yield to the operating\n system and wait).\n\n o os_yields indicates the number of times a the thread trying to lock\n a mutex gave up its timeslice and yielded to the operating system\n (on the presumption that allowing other threads to run will free\n the mutex so that it can be locked).\n\n o os_wait_times indicates the amount of time (in ms) spent in\n operating system waits, if the timed_mutexes system variable is 1\n (ON). If timed_mutexes is 0 (OFF), timing is disabled, so\n os_wait_times is 0. timed_mutexes is off by default.\n\nFrom MySQL 5.1.15 on, the statement displays the following output\nfields:\n\no Type\n\n Always InnoDB.\n\no Name\n\n The source file where the mutex is implemented, and the line number\n in the file where the mutex is created. The line number may change\n depending on your version of MySQL.\n\no Status\n\n This field displays the same values as previously described (count,\n spin_waits, spin_rounds, os_waits, os_yields, os_wait_times), but\n only if UNIV_DEBUG was defined at MySQL compilation time (for\n example, in include/univ.h in the InnoDB part of the MySQL source\n tree). If UNIV_DEBUG was not defined, the statement displays only the\n os_waits value. In the latter case (without UNIV_DEBUG), the\n information on which the output is based is insufficient to\n distinguish regular mutexes and mutexes that protect rw-locks (which\n allow multiple readers or a single writer).

For maximal compatibility, plugin names should be\nlimited to ASCII letters, digits, and underscore, because they are used\nin C source files, shell command lines, M4 and Bourne shell scripts,\nand SQL environments.\n\nplugin_library is the name of the shared library that contains the\nplugin code. The name includes the file name extension (for example,\nlibmyplugin.so or libmyplugin.dylib).\n\nThe shared library must be located in the plugin directory (that is,\nthe directory named by the plugin_dir system variable). The library\nmust be in the plugin directory itself, not in a subdirectory. By\ndefault, plugin_dir is plugin directory under the directory named by\nthe pkglibdir configuration variable, but it can be changed by setting\nthe value of plugin_dir at server startup. For example, set its value\nin a my.cnf file:\n\n[mysqld]\nplugin_dir=/path/to/plugin/directory\n\nIf the value of plugin_dir is a relative path name, it is taken to be\nrelative to the MySQL base directory (the value of the basedir system\nvariable).\n\nINSTALL PLUGIN adds a line to the mysql.plugin table that describes the\nplugin. This table contains the plugin name and library file name.\n\nAs of MySQL 5.1.33, INSTALL PLUGIN causes the server to read option\n(my.cnf) files just as during server startup. This enables the plugin\nto pick up any relevant options from those files. It is possible to add\nplugin options to an option file even before loading a plugin (if the\nloose prefix is used). It is also possible to uninstall a plugin, edit\nmy.cnf, and install the plugin again. Restarting the plugin this way\nenables it to the new option values without a server restart.\n\nBefore MySQL 5.1.33, a plugin is started with each option set to its\ndefault value.\n\nINSTALL PLUGIN also loads and initializes the plugin code to make the\nplugin available for use. A plugin is initialized by executing its\ninitialization function, which handles any setup that the plugin must\nperform before it can be used.\n\nTo use INSTALL PLUGIN, you must have the INSERT privilege for the\nmysql.plugin table.\n\nAt server startup, the server loads and initializes any plugin that is\nlisted in the mysql.plugin table.

To write data from\na table to a file, use SELECT ... INTO OUTFILE. To read the file back\ninto a table, use LOAD DATA INFILE. The syntax of the FIELDS and LINES\nclauses is the same for both statements. Both clauses are optional, but\nFIELDS must precede LINES if both are specified.\n\nFor more information about the efficiency of INSERT versus LOAD DATA\nINFILE and speeding up LOAD DATA INFILE, see\nhttp://dev.mysql.com/doc/refman/5.1/en/insert-speed.html.\n\nThe character set indicated by the character_set_database system\nvariable is used to interpret the information in the file. SET NAMES\nand the setting of character_set_client do not affect interpretation of\ninput. If the contents of the input file use a character set that\ndiffers from the default, it is usually preferable to specify the\ncharacter set of the file by using the CHARACTER SET clause, which is\navailable as of MySQL 5.1.17.\n\nLOAD DATA INFILE interprets all fields in the file as having the same\ncharacter set, regardless of the data types of the columns into which\nfield values are loaded. For proper interpretation of file contents,\nyou must ensure that it was written with the correct character set. For\nexample, if you write a data file with mysqldump -T or by issuing a\nSELECT ... INTO OUTFILE statement in mysql, be sure to use a\n--default-character-set option with mysqldump or mysql so that output\nis written in the character set to be used when the file is loaded with\nLOAD DATA INFILE.\n\nNote that it is currently not possible to load data files that use the\nucs2, utf16, or utf32 character set.\n\nAs of MySQL 5.1.6, the character_set_filesystem system variable\ncontrols the interpretation of the file name.\n\nYou can also load data files by using the mysqlimport utility; it\noperates by sending a LOAD DATA INFILE statement to the server. The\n--local option causes mysqlimport to read data files from the client\nhost. You can specify the --compress option to get better performance\nover slow networks if the client and server support the compressed\nprotocol. See http://dev.mysql.com/doc/refman/5.1/en/mysqlimport.html.\n\nIf you use LOW_PRIORITY, execution of the LOAD DATA statement is\ndelayed until no other clients are reading from the table. This affects\nonly storage engines that use only table-level locking (MyISAM, MEMORY,\nMERGE).\n\nIf you specify CONCURRENT with a MyISAM table that satisfies the\ncondition for concurrent inserts (that is, it contains no free blocks\nin the middle), other threads can retrieve data from the table while\nLOAD DATA is executing. Using this option affects the performance of\nLOAD DATA a bit, even if no other thread is using the table at the same\ntime.\n\nCONCURRENT is not replicated when using statement-based replication;\nhowever, it is replicated when using row-based replication. See\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-features-load-data.…, for more information.\n\n*Note*: Prior to MySQL 5.1.23, LOAD DATA performed very poorly when\nimporting into partitioned tables. The statement now uses buffering to\nimprove performance; however, the buffer uses 130 KB memory per\npartition to achieve this. (Bug#26527 (http://bugs.mysql.com/26527))\n\nThe LOCAL keyword, if specified, is interpreted with respect to the\nclient end of the connection:\n\no If LOCAL is specified, the file is read by the client program on the\n client host and sent to the server. The file can be given as a full\n path name to specify its exact location. If given as a relative path\n name, the name is interpreted relative to the directory in which the\n client program was started.\n\no If LOCAL is not specified, the file must be located on the server\n host and is read directly by the server. The server uses the\n following rules to locate the file:\n\n o If the file name is an absolute path name, the server uses it as\n given.\n\n o If the file name is a relative path name with one or more leading\n components, the server searches for the file relative to the\n server\'s data directory.\n\n o If a file name with no leading components is given, the server\n looks for the file in the database directory of the default\n database.\n\nNote that, in the non-LOCAL case, these rules mean that a file named as\n./myfile.txt is read from the server\'s data directory, whereas the file\nnamed as myfile.txt is read from the database directory of the default\ndatabase.

For example, to set\nthe default isolation level to REPEATABLE READ, use these lines in the\n[mysqld] section of an option file:\n\n[mysqld]\ntransaction-isolation = REPEATABLE-READ\n\nTo determine the global and session transaction isolation levels at\nruntime, check the value of the tx_isolation system variable:\n\nSELECT @@GLOBAL.tx_isolation, @@tx_isolation;\n\nInnoDB supports each of the translation isolation levels described here\nusing different locking strategies. The default level is REPEATABLE\nREAD. For additional information about InnoDB record-level locks and\nhow it uses them to execute various types of statements, see\nhttp://dev.mysql.com/doc/refman/5.1/en/innodb-record-level-locks.html,… http://dev.mysql.com/doc/refman/5.1/en/innodb-locks-set.html.\n\nThe following list describes how MySQL supports the different\ntransaction levels:\n\no READ UNCOMMITTED\n\n SELECT statements are performed in a non-locking fashion, but a\n possible earlier version of a row might be used. Thus, using this\n isolation level, such reads are not consistent. This is also called a\n "dirty read." Otherwise, this isolation level works like READ\n COMMITTED.\n\no READ COMMITTED\n\n A somewhat Oracle-like isolation level with respect to consistent\n (non-locking) reads: Each consistent read, even within the same\n transaction, sets and reads its own fresh snapshot. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n InnoDB locks only index records, not the gaps before them, and thus\n allows the free insertion of new records next to locked records. For\n UPDATE and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition (such as\n WHERE id = 100), or a range-type search condition (such as WHERE id >\n 100). For a unique index with a unique search condition, InnoDB locks\n only the index record found, not the gap before it. For range-type\n searches, InnoDB locks the index range scanned, using gap locks or\n next-key (gap plus index-record) locks to block insertions by other\n sessions into the gaps covered by the range. This is necessary\n because "phantom rows" must be blocked for MySQL replication and\n recovery to work.\n\n *Note*: In MySQL 5.1, if the READ COMMITTED isolation level is used\n or the innodb_locks_unsafe_for_binlog system variable is enabled,\n there is no InnoDB gap locking except for foreign-key constraint\n checking and duplicate-key checking. Also, record locks for\n non-matching rows are released after MySQL has evaluated the WHERE\n condition. As of MySQL 5.1, if you use READ COMMITTED or enable\n innodb_locks_unsafe_for_binlog, you must use row-based binary\n logging.\n\no REPEATABLE READ\n\n This is the default isolation level for InnoDB. For consistent reads,\n there is an important difference from the READ COMMITTED isolation\n level: All consistent reads within the same transaction read the\n snapshot established by the first read. This convention means that if\n you issue several plain (non-locking) SELECT statements within the\n same transaction, these SELECT statements are consistent also with\n respect to each other. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n UPDATE, and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition, or a\n range-type search condition. For a unique index with a unique search\n condition, InnoDB locks only the index record found, not the gap\n before it. For other search conditions, InnoDB locks the index range\n scanned, using gap locks or next-key (gap plus index-record) locks to\n block insertions by other sessions into the gaps covered by the\n range.\n\no SERIALIZABLE\n\n This level is like REPEATABLE READ, but InnoDB implicitly converts\n all plain SELECT statements to SELECT ... LOCK IN SHARE MODE if\n autocommit is disabled. If autocommit is enabled, the SELECT is its\n own transaction. It therefore is known to be read only and can be\n serialized if performed as a consistent (non-locking) read and need\n not block for other transactions. (This means that to force a plain\n SELECT to block if other transactions have modified the selected\n rows, you should disable autocommit.)\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (445,4,'CEILING','Syntax:\nCEILING(X)\n\nReturns the smallest integer value not less than X.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT CEILING(1.23);\n -> 2\nmysql> SELECT CEILING(-1.23);\n -> -1\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (446,4,'SIN','Syntax:\nSIN(X)\n\nReturns the sine of X, where X is given in radians.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT SIN(PI());\n -> 1.2246063538224e-16\nmysql> SELECT ROUND(SIN(PI()));\n -> 0\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (447,30,'DAYOFWEEK','Syntax:\nDAYOFWEEK(date)\n\nReturns the weekday index for date (1 = Sunday, 2 = Monday, ..., 7 =\nSaturday).

To create the view explicitly in a given database,\nspecify the name as db_name.view_name when you create it.\n\nmysql> CREATE VIEW test.v AS SELECT * FROM t;\n\nBase tables and views share the same namespace within a database, so a\ndatabase cannot contain a base table and a view that have the same\nname.\n\nViews must have unique column names with no duplicates, just like base\ntables. By default, the names of the columns retrieved by the SELECT\nstatement are used for the view column names. To define explicit names\nfor the view columns, the optional column_list clause can be given as a\nlist of comma-separated identifiers. The number of names in column_list\nmust be the same as the number of columns retrieved by the SELECT\nstatement.\n\n*Note*: Prior to MySQL 5.1.29, When you modify an existing view, the\ncurrent view definition is backed up and saved. It is stored in that\ntable\'s database directory, in a subdirectory named arc. The backup\nfile for a view v is named v.frm-00001. If you alter the view again,\nthe next backup is named v.frm-00002. The three latest view backup\ndefinitions are stored. Backed up view definitions are not preserved by\nmysqldump, or any other such programs, but you can retain them using a\nfile copy operation. However, they are not needed for anything but to\nprovide you with a backup of your previous view definition. It is safe\nto remove these backup definitions, but only while mysqld is not\nrunning. If you delete the arc subdirectory or its files while mysqld\nis running, you will receive an error the next time you try to alter\nthe view: mysql> ALTER VIEW v AS SELECT * FROM t; ERROR 6 (HY000):\nError on delete of \'.\\test\\arc/v.frm-0004\' (Errcode: 2)\n\nColumns retrieved by the SELECT statement can be simple references to\ntable columns. They can also be expressions that use functions,\nconstant values, operators, and so forth.\n\nUnqualified table or view names in the SELECT statement are interpreted\nwith respect to the default database. A view can refer to tables or\nviews in other databases by qualifying the table or view name with the\nproper database name.\n\nA view can be created from many kinds of SELECT statements. It can\nrefer to base tables or other views. It can use joins, UNION, and\nsubqueries. The SELECT need not even refer to any tables. The following\nexample defines a view that selects two columns from another table, as\nwell as an expression calculated from those columns:\n\nmysql> CREATE TABLE t (qty INT, price INT);\nmysql> INSERT INTO t VALUES(3, 50);\nmysql> CREATE VIEW v AS SELECT qty, price, qty*price AS value FROM t;\nmysql> SELECT * FROM v;\n+------+-------+-------+\n| qty | price | value |\n+------+-------+-------+\n| 3 | 50 | 150 |\n+------+-------+-------+\n\nA view definition is subject to the following restrictions:\n\no The SELECT statement cannot contain a subquery in the FROM clause.\n\no The SELECT statement cannot refer to system or user variables.\n\no Within a stored program, the definition cannot refer to program\n parameters or local variables.\n\no The SELECT statement cannot refer to prepared statement parameters.\n\no Any table or view referred to in the definition must exist. However,\n after a view has been created, it is possible to drop a table or view\n that the definition refers to. In this case, use of the view results\n in an error. To check a view definition for problems of this kind,\n use the CHECK TABLE statement.\n\no The definition cannot refer to a TEMPORARY table, and you cannot\n create a TEMPORARY view.\n\no Any tables named in the view definition must exist at definition\n time.\n\no You cannot associate a trigger with a view.\n\nORDER BY is allowed in a view definition, but it is ignored if you\nselect from a view using a statement that has its own ORDER BY.\n\nFor other options or clauses in the definition, they are added to the\noptions or clauses of the statement that references the view, but the\neffect is undefined. For example, if a view definition includes a LIMIT\nclause, and you select from the view using a statement that has its own\nLIMIT clause, it is undefined which limit applies. This same principle\napplies to options such as ALL, DISTINCT, or SQL_SMALL_RESULT that\nfollow the SELECT keyword, and to clauses such as INTO, FOR UPDATE,\nLOCK IN SHARE MODE, and PROCEDURE.\n\nIf you create a view and then change the query processing environment\nby changing system variables, that may affect the results that you get\nfrom the view:\n\nmysql> CREATE VIEW v (mycol) AS SELECT \'abc\';\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> SET sql_mode = \'\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| mycol | \n+-------+\n1 row in set (0.01 sec)\n\nmysql> SET sql_mode = \'ANSI_QUOTES\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| abc | \n+-------+\n1 row in set (0.00 sec)\n\nThe DEFINER and SQL SECURITY clauses determine which MySQL account to\nuse when checking access privileges for the view when a statement is\nexecuted that references the view. They were addded in MySQL 5.1.2. The\nlegal SQL SECURITY characteristic values are DEFINER and INVOKER. These\nindicate that the required privileges must be held by the user who\ndefined or invoked the view, respectively. The default SQL SECURITY\nvalue is DEFINER.\n\nIf a user value is given for the DEFINER clause, it should be a MySQL\naccount in \'user_name\'@\'host_name\' format (the same format used in the\nGRANT statement). The user_name and host_name values both are required.\nThe definer can also be given as CURRENT_USER or CURRENT_USER(). The\ndefault DEFINER value is the user who executes the CREATE VIEW\nstatement. This is the same as specifying DEFINER = CURRENT_USER\nexplicitly.\n\nIf you specify the DEFINER clause, these rules determine the legal\nDEFINER user values:\n\no If you do not have the SUPER privilege, the only legal user value is\n your own account, either specified literally or by using\n CURRENT_USER. You cannot set the definer to some other account.\n\no If you have the SUPER privilege, you can specify any syntactically\n legal account name. If the account does not actually exist, a warning\n is generated.\n\no If the SQL SECURITY value is DEFINER but the definer account does not\n exist when the view is referenced, an error occurs.\n\nWithin a view definition, CURRENT_USER returns the view\'s DEFINER value\nby default as of MySQL 5.1.12. For older versions, and for views\ndefined with the SQL SECURITY INVOKER characteristic, CURRENT_USER\nreturns the account for the view\'s invoker. For information about user\nauditing within views, see\nhttp://dev.mysql.com/doc/refman/5.1/en/account-activity-auditing.html.… a stored routine that is defined with the SQL SECURITY DEFINER\ncharacteristic, CURRENT_USER returns the routine\'s DEFINER value. This\nalso affects a view defined within such a program, if the view\ndefinition contains a DEFINER value of CURRENT_USER.\n\nAs of MySQL 5.1.2 (when the DEFINER and SQL SECURITY clauses were\nimplemented), view privileges are checked like this:\n\no At view definition time, the view creator must have the privileges\n needed to use the top-level objects accessed by the view. For\n example, if the view definition refers to table columns, the creator\n must have privileges for the columns, as described previously. If the\n definition refers to a stored function, only the privileges needed to\n invoke the function can be checked. The privileges required when the\n function runs can be checked only as it executes: For different\n invocations of the function, different execution paths within the\n function might be taken.\n\no When a view is referenced, privileges for objects accessed by the\n view are checked against the privileges held by the view creator or\n invoker, depending on whether the SQL SECURITY characteristic is\n DEFINER or INVOKER, respectively.\n\no If reference to a view causes execution of a stored function,\n privilege checking for statements executed within the function depend\n on whether the function is defined with a SQL SECURITY characteristic\n of DEFINER or INVOKER. If the security characteristic is DEFINER, the\n function runs with the privileges of its creator. If the\n characteristic is INVOKER, the function runs with the privileges\n determined by the view\'s SQL SECURITY characteristic.\n\nPrior to MySQL 5.1.2 (before the DEFINER and SQL SECURITY clauses were\nimplemented), privileges required for objects used in a view are\nchecked at view creation time.\n\nExample: A view might depend on a stored function, and that function\nmight invoke other stored routines. For example, the following view\ninvokes a stored function f():\n\nCREATE VIEW v AS SELECT * FROM t WHERE t.id = f(t.name);\n\nSuppose that f() contains a statement such as this:\n\nIF name IS NULL then\n CALL p1();\nELSE\n CALL p2();\nEND IF;\n\nThe privileges required for executing statements within f() need to be\nchecked when f() executes. This might mean that privileges are needed\nfor p1() or p2(), depending on the execution path within f(). Those\nprivileges must be checked at runtime, and the user who must possess\nthe privileges is determined by the SQL SECURITY values of the view v\nand the function f().\n\nThe DEFINER and SQL SECURITY clauses for views are extensions to\nstandard SQL. In standard SQL, views are handled using the rules for\nSQL SECURITY INVOKER.\n\nIf you invoke a view that was created before MySQL 5.1.2, it is treated\nas though it was created with a SQL SECURITY DEFINER clause and with a\nDEFINER value that is the same as your account. However, because the\nactual definer is unknown, MySQL issues a warning. To make the warning\ngo away, it is sufficient to re-create the view so that the view\ndefinition includes a DEFINER clause.\n\nThe optional ALGORITHM clause is a MySQL extension to standard SQL. It\naffects how MySQL processes the view. ALGORITHM takes three values:\nMERGE, TEMPTABLE, or UNDEFINED. The default algorithm is UNDEFINED if\nno ALGORITHM clause is present. For more information, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-algorithms.html.\n\nSome views are updatable. That is, you can use them in statements such\nas UPDATE, DELETE, or INSERT to update the contents of the underlying\ntable. For a view to be updatable, there must be a one-to-one\nrelationship between the rows in the view and the rows in the\nunderlying table. There are also certain other constructs that make a\nview non-updatable.\n\nThe WITH CHECK OPTION clause can be given for an updatable view to\nprevent inserts or updates to rows except those for which the WHERE\nclause in the select_statement is true.\n\nIn a WITH CHECK OPTION clause for an updatable view, the LOCAL and\nCASCADED keywords determine the scope of check testing when the view is\ndefined in terms of another view. The LOCAL keyword restricts the CHECK\nOPTION only to the view being defined. CASCADED causes the checks for\nunderlying views to be evaluated as well. When neither keyword is\ngiven, the default is CASCADED.\n\nFor more information about updatable views and the WITH CHECK OPTION\nclause, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-updatability.html.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-view.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-view.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (452,35,'TRIM','Syntax:\nTRIM([{BOTH | LEADING | TRAILING} [remstr] FROM] str), TRIM([remstr\nFROM] str)\n\nReturns the string str with all remstr prefixes or suffixes removed.

This is a common situation\nwhen you use MySQL for logging and you also periodically run SELECT and\nUPDATE statements that take a long time to complete.\n\nWhen a client uses INSERT DELAYED, it gets an okay from the server at\nonce, and the row is queued to be inserted when the table is not in use\nby any other thread.\n\nAnother major benefit of using INSERT DELAYED is that inserts from many\nclients are bundled together and written in one block. This is much\nfaster than performing many separate inserts.\n\nNote that INSERT DELAYED is slower than a normal INSERT if the table is\nnot otherwise in use. There is also the additional overhead for the\nserver to handle a separate thread for each table for which there are\ndelayed rows. This means that you should use INSERT DELAYED only when\nyou are really sure that you need it.\n\nThe queued rows are held only in memory until they are inserted into\nthe table.

This is used by ANALYSE() to check\n whether the optimal data type should be of type ENUM; if there are\n more than max_elements distinct values, then ENUM is not a suggested\n type.\n\no max_memory (default 8192) is the maximum amount of memory that\n ANALYSE() should allocate per column while trying to find all\n distinct values.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/procedure-analyse.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/procedure-analyse.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (184,25,'CHANGE MASTER TO','Syntax:\nCHANGE MASTER TO master_def [, master_def] ...\n\nmaster_def:\n MASTER_BIND = \'interface_name\'\n | MASTER_HOST = \'host_name\'\n | MASTER_USER = \'user_name\'\n | MASTER_PASSWORD = \'password\'\n | MASTER_PORT = port_num\n | MASTER_CONNECT_RETRY = interval\n | MASTER_HEARTBEAT_PERIOD = interval\n | MASTER_LOG_FILE = \'master_log_name\'\n | MASTER_LOG_POS = master_log_pos\n | RELAY_LOG_FILE = \'relay_log_name\'\n | RELAY_LOG_POS = relay_log_pos\n | MASTER_SSL = {0|1}\n | MASTER_SSL_CA = \'ca_file_name\'\n | MASTER_SSL_CAPATH = \'ca_directory_name\'\n | MASTER_SSL_CERT = \'cert_file_name\'\n | MASTER_SSL_KEY = \'key_file_name\'\n | MASTER_SSL_CIPHER = \'cipher_list\'\n | MASTER_SSL_VERIFY_SERVER_CERT = {0|1}\n\nCHANGE MASTER TO changes the parameters that the slave server uses for\nconnecting to and communicating with the master server. It also updates\nthe contents of the master.info and relay-log.info files.\n\nMASTER_USER, MASTER_PASSWORD, MASTER_SSL, MASTER_SSL_CA,\nMASTER_SSL_CAPATH, MASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER,\nand MASTER_SSL_VERIFY_SERVER_CERT provide information to the slave\nabout how to connect to its master. MASTER_SSL_VERIFY_SERVER_CERT was\nadded in MySQL 5.1.18. It is used as described for the\n--ssl-verify-server-cert option in\nhttp://dev.mysql.com/doc/refman/5.1/en/ssl-options.html.\n\nMASTER_CONN… specifies how many seconds to wait between connect\nretries. The default is 60. The number of reconnection attempts is\nlimited by the --master-retry-count server option; for more\ninformation, see\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-options.html.\n\nThe SSL options (MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH,\nMASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER), and\nMASTER_SSL_VERIFY_SERVER_CERT can be changed even on slaves that are\ncompiled without SSL support. They are saved to the master.info file,\nbut are ignored unless you use a server that has SSL support enabled.\n\nIf you don\'t specify a given parameter, it keeps its old value, except\nas indicated in the following discussion. For example, if the password\nto connect to your MySQL master has changed, you just need to issue\nthese statements to tell the slave about the new password:\n\nSTOP SLAVE; -- if replication was running\nCHANGE MASTER TO MASTER_PASSWORD=\'new3cret\';\nSTART SLAVE; -- if you want to restart replication\n\nThere is no need to specify the parameters that do not change (host,\nport, user, and so forth).\n\nMASTER_HOST and MASTER_PORT are the host name (or IP address) of the\nmaster host and its TCP/IP port.\n\nThe next two options are available only in MySQL Cluster NDB 6.3 and\n6.4; they are not supported in mainline MySQL 5.1:\n\no MASTER_BIND is for use on replication slaves having multiple network\n interfaces, and determines which of the slave\'s network interfaces is\n chosen for connecting to the master. It is also possible to determine\n which network interface is to be used in such cases by starting the\n slave mysqld process with the --master-bind option.\n\n The ability to bind a replication slave to specific network interface\n was added in MySQL Cluster NDB 6.3.4.\n\no MASTER_HEARTBEAT_PERIOD is used to set the interval in seconds\n between replication heartbeats. Whenever the master\'s binlog is\n updated with an event, the waiting period for the next heartbeat is\n reset. interval is a decimal value having the range 0 to 4294967\n seconds and a resolution to hundredths of a second; the smallest\n nonzero value is 0.001. Heartbeats are sent by the master only if\n there are no unsent events in the binlog file for a period longer\n than interval.\n\n Setting interval to 0 disables heartbeats altogether. The default\n value for interval is equal to the value of slave_net_timeout divided\n by 2.\n\n *Note*: Setting @@global.slave_net_timeout to a value less than that\n of the current heartbeat interval results in a warning being issued.\n\n Issuing RESET SLAVE resets the heartbeat interval to the default.\n\n MASTER_HEARTBEAT_PERIOD was added in MySQL Cluster NDB 6.3.4.\n\n*Note*: Replication cannot use Unix socket files. You must be able to\nconnect to the master MySQL server using TCP/IP.\n\nIf you specify MASTER_HOST or MASTER_PORT, the slave assumes that the\nmaster server is different from before (even if you specify a host or\nport value that is the same as the current value.) In this case, the\nold values for the master binary log name and position are considered\nno longer applicable, so if you do not specify MASTER_LOG_FILE and\nMASTER_LOG_POS in the statement, MASTER_LOG_FILE=\'\' and\nMASTER_LOG_POS=4 are silently appended to it.\n\nSetting MASTER_HOST=\'\' --- that is, setting its value explicitly to an\nempty string --- is not the same as not setting it at all. Setting this\noption to an empty string causes START SLAVE subsequently to fail. This\nissue is addressed in MySQL 6.0. (Bug#28796\n(http://bugs.mysql.com/28796))\n\nMASTER_LOG_FILE and MASTER_LOG_POS are the coordinates at which the\nslave I/O thread should begin reading from the master the next time the\nthread starts. If you specify either of them, you cannot specify\nRELAY_LOG_FILE or RELAY_LOG_POS. If neither of MASTER_LOG_FILE or\nMASTER_LOG_POS are specified, the slave uses the last coordinates of\nthe slave SQL thread before CHANGE MASTER TO was issued. This ensures\nthat there is no discontinuity in replication, even if the slave SQL\nthread was late compared to the slave I/O thread, when you merely want\nto change, say, the password to use.\n\nCHANGE MASTER TO deletes all relay log files and starts a new one,\nunless you specify RELAY_LOG_FILE or RELAY_LOG_POS. In that case, relay\nlogs are kept; the relay_log_purge global variable is set silently to\n0.\n\nCHANGE MASTER TO is useful for setting up a slave when you have the\nsnapshot of the master and have recorded the log and the offset\ncorresponding to it. After loading the snapshot into the slave, you can\nrun CHANGE MASTER TO MASTER_LOG_FILE=\'log_name_on_master\',\nMASTER_LOG_POS=log_offset_on_master on the slave.\n\nThe following example changes the master and master\'s binary log\ncoordinates. This is used when you want to set up the slave to\nreplicate the master:\n\nCHANGE MASTER TO\n MASTER_HOST=\'master2.mycompany.com\',\n MASTER_USER=\'replication\',\n MASTER_PASSWORD=\'bigs3cret\',\n MASTER_PORT=3306,\n MASTER_LOG_FILE=\'master2-bin.001\',\n MASTER_LOG_POS=4,\n MASTER_CONNECT_RETRY=10;\n\nThe next example shows an operation that is less frequently employed.\nIt is used when the slave has relay logs that you want it to execute\nagain for some reason. To do this, the master need not be reachable.\nYou need only use CHANGE MASTER TO and start the SQL thread (START\nSLAVE SQL_THREAD):\n\nCHANGE MASTER TO\n RELAY_LOG_FILE=\'slave-relay-bin.006\',\n RELAY_LOG_POS=4025;\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (185,37,'DROP DATABASE','Syntax:\nDROP {DATABASE | SCHEMA} [IF EXISTS] db_name\n\nDROP DATABASE drops all tables in the database and deletes the\ndatabase.

One data file is\ncreated and added to the tablespace using this statement. Additional\ndata files may be added to the tablespace by using the ALTER TABLESPACE\nstatement (see [HELP ALTER TABLESPACE]). For rules covering the naming\nof tablespaces, see\nhttp://dev.mysql.com/doc/refman/5.1/en/identifiers.html.\n\n*Note*: All MySQL Cluster Disk Data objects share the same namespace.\nThis means that each Disk Data object must be uniquely named (and not\nmerely each Disk Data object of a given type). For example, you cannot\nhave a tablespace and a log file group with the same name, or a\ntablespace and a data file with the same name.\n\nPrior to MySQL Cluster NDB 6.2.17, 6.3.23, and 6.4.3, path and file\nnames for data files could not be longer than 128 characters.\n(Bug#31770 (http://bugs.mysql.com/31770))\n\nA log file group of one or more UNDO log files must be assigned to the\ntablespace to be created with the USE LOGFILE GROUP clause.\nlogfile_group must be an existing log file group created with CREATE\nLOGFILE GROUP (see\nhttp://dev.mysql.com/doc/refman/5.1/en/create-logfile-group.html).\nMu… tablespaces may use the same log file group for UNDO logging.\n\nThe EXTENT_SIZE sets the size, in bytes, of the extents used by any\nfiles belonging to the tablespace. The default value is 1M. The minimum\nsize is 32K, and theoretical maximum is 2G, although the practical\nmaximum size depends on a number of factors. In most cases, changing\nthe extent size does not have any measurable effect on performance, and\nthe default value is recommended for all but the most unusual\nsituations.\n\nAn extent is a unit of disk space allocation. One extent is filled with\nas much data as that extent can contain before another extent is used.\nIn theory, up to 65,535 (64K) extents may used per data file; however,\nthe recommended maximum is 32,768 (32K). The recommended maximum size\nfor a single data file is 32G --- that is, 32K extents x 1 MB per\nextent. In addition, once an extent is allocated to a given partition,\nit cannot be used to store data from a different partition; an extent\ncannot store data from more than one partition. This means, for example\nthat a tablespace having a single datafile whose INITIAL_SIZE is 256 MB\nand whose EXTENT_SIZE is 128M has just two extents, and so can be used\nto store data from at most two different disk data table partitions.\n\nYou can see how many extents remain free in a given data file by\nquerying the INFORMATION_SCHEMA.FILES table, and so derive an estimate\nfor how much space remains free in the file. For further discussion and\nexamples, see http://dev.mysql.com/doc/refman/5.1/en/files-table.html.\n\nThe INITIAL_SIZE parameter sets the data file\'s total size in bytes.\nOnce the file has been created, its size cannot be changed; however,\nyou can add more data files to the tablespace using ALTER TABLESPACE\n... ADD DATAFILE. See [HELP ALTER TABLESPACE].\n\nINITIAL_SIZE is optional; its default value is 128M.\n\nOn 32-bit systems, the maximum supported value for INITIAL_SIZE is 4G.\n(Bug#29186 (http://bugs.mysql.com/29186))\n\nWhen setting EXTENT_SIZE or INITIAL_SIZE (either or both), you may\noptionally follow the number with a one-letter abbreviation for an\norder of magnitude, similar to those used in my.cnf. Generally, this is\none of the letters M (for megabytes) or G (for gigabytes).\n\nAUTOEXTEND_SIZE, MAX_SIZE, NODEGROUP, WAIT, and COMMENT are parsed but\nignored, and so have no effect in MySQL 5.1. These options are intended\nfor future expansion.\n\nThe ENGINE parameter determines the storage engine which uses this\ntablespace, with engine_name being the name of the storage engine. In\nMySQL 5.1, engine_name must be one of the values NDB or NDBCLUSTER.\n\nWhen CREATE TABLESPACE is used with ENGINE = NDB, a tablespace and\nassociated data file are created on each Cluster data node. You can\nverify that the data files were created and obtain information about\nthem by querying the INFORMATION_SCHEMA.FILES table. For example:\n\nmysql> SELECT LOGFILE_GROUP_NAME, FILE_NAME, EXTRA\n -> FROM INFORMATION_SCHEMA.FILES\n -> WHERE TABLESPACE_NAME = \'newts\' AND FILE_TYPE = \'DATAFILE\';\n+--------------------+-------------+----------------+\n| LOGFILE_GROUP_NAME | FILE_NAME | EXTRA |\n+--------------------+-------------+----------------+\n| lg_3 | newdata.dat | CLUSTER_NODE=3 |\n| lg_3 | newdata.dat | CLUSTER_NODE=4 |\n+--------------------+-------------+----------------+\n2 rows in set (0.01 sec)\n\n(See http://dev.mysql.com/doc/refman/5.1/en/files-table.html.)\n\nCREATE TABLESPACE was added in MySQL 5.1.6.

By default, a routine is\nassociated with the default database. To associate the routine\nexplicitly with a given database, specify the name as db_name.sp_name\nwhen you create it.\n\nThe CREATE FUNCTION statement is also used in MySQL to support UDFs\n(user-defined functions). See\nhttp://dev.mysql.com/doc/refman/5.1/en/adding-functions.html. A UDF can\nbe regarded as an external stored function. However, do note that\nstored functions share their namespace with UDFs. See\nhttp://dev.mysql.com/doc/refman/5.1/en/function-resolution.html, for\nthe rules describing how the server interprets references to different\nkinds of functions.\n\nTo invoke a stored procedure, use the CALL statement (see [HELP CALL]).\nTo invoke a stored function, refer to it in an expression. The function\nreturns a value during expression evaluation.\n\nTo execute the CREATE PROCEDURE or CREATE FUNCTION statement, it is\nnecessary to have the CREATE ROUTINE privilege. By default, MySQL\nautomatically grants the ALTER ROUTINE and EXECUTE privileges to the\nroutine creator. This behavior can be changed by disabling the\nautomatic_sp_privileges system variable. See\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.html… binary logging is enabled, the CREATE FUNCTION statement might also\nrequire the SUPER privilege, as described in\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-logging.html.\n\… DEFINER and SQL SECURITY clauses specify the security context to be\nused when checking access privileges at routine execution time, as\ndescribed later.\n\nIf the routine name is the same as the name of a built-in SQL function,\na syntax error occurs unless you use a space between the name and the\nfollowing parenthesis when defining the routine or invoking it later.\nFor this reason, avoid using the names of existing SQL functions for\nyour own stored routines.\n\nThe IGNORE_SPACE SQL mode applies to built-in functions, not to stored\nroutines. It is always allowable to have spaces after a stored routine\nname, regardless of whether IGNORE_SPACE is enabled.\n\nThe parameter list enclosed within parentheses must always be present.\nIf there are no parameters, an empty parameter list of () should be\nused. Parameter names are not case sensitive.\n\nEach parameter is an IN parameter by default. To specify otherwise for\na parameter, use the keyword OUT or INOUT before the parameter name.\n\n*Note*: Specifying a parameter as IN, OUT, or INOUT is valid only for a\nPROCEDURE. (FUNCTION parameters are always regarded as IN parameters.)\n\nAn IN parameter passes a value into a procedure. The procedure might\nmodify the value, but the modification is not visible to the caller\nwhen the procedure returns. An OUT parameter passes a value from the\nprocedure back to the caller. Its initial value is NULL within the\nprocedure, and its value is visible to the caller when the procedure\nreturns. An INOUT parameter is initialized by the caller, can be\nmodified by the procedure, and any change made by the procedure is\nvisible to the caller when the procedure returns.\n\nFor each OUT or INOUT parameter, pass a user-defined variable in the\nCALL statement that invokes the procedure so that you can obtain its\nvalue when the procedure returns. If you are calling the procedure from\nwithin another stored procedure or function, you can also pass a\nroutine parameter or local routine variable as an IN or INOUT\nparameter.\n\nThe following example shows a simple stored procedure that uses an OUT\nparameter:\n\nmysql> delimiter //\n\nmysql> CREATE PROCEDURE simpleproc (OUT param1 INT)\n -> BEGIN\n -> SELECT COUNT(*) INTO param1 FROM t;\n -> END//\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> delimiter ;\n\nmysql> CALL simpleproc(@a);\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT @a;\n+------+\n| @a |\n+------+\n| 3 |\n+------+\n1 row in set (0.00 sec)\n\nThe example uses the mysql client delimiter command to change the\nstatement delimiter from ; to // while the procedure is being defined.\nThis allows the ; delimiter used in the procedure body to be passed\nthrough to the server rather than being interpreted by mysql itself.\nSee\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-defini… RETURNS clause may be specified only for a FUNCTION, for which it\nis mandatory. It indicates the return type of the function, and the\nfunction body must contain a RETURN value statement. If the RETURN\nstatement returns a value of a different type, the value is coerced to\nthe proper type. For example, if a function specifies an ENUM or SET\nvalue in the RETURNS clause, but the RETURN statement returns an\ninteger, the value returned from the function is the string for the\ncorresponding ENUM member of set of SET members.\n\nThe following example function takes a parameter, performs an operation\nusing an SQL function, and returns the result. In this case, it is\nunnecessary to use delimiter because the function definition contains\nno internal ; statement delimiters:\n\nmysql> CREATE FUNCTION hello (s CHAR(20))\nmysql> RETURNS CHAR(50) DETERMINISTIC\n -> RETURN CONCAT(\'Hello, \',s,\'!\');\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT hello(\'world\');\n+----------------+\n| hello(\'world\') |\n+----------------+\n| Hello, world! |\n+----------------+\n1 row in set (0.00 sec)\n\nParameter types and function return types can be declared to use any\nvalid data type, except that the COLLATE attribute cannot be used.\n\nThe routine_body consists of a valid SQL procedure statement. This can\nbe a simple statement such as SELECT or INSERT, or it can be a compound\nstatement written using BEGIN and END. Compound statements can contain\ndeclarations, loops, and other control structure statements. The syntax\nfor these statements is described in\nhttp://dev.mysql.com/doc/refman/5.1/en/sql-syntax-compound-statements.h… allows routines to contain DDL statements, such as CREATE and\nDROP. MySQL also allows stored procedures (but not stored functions) to\ncontain SQL transaction statements such as COMMIT. Stored functions may\nnot contain statements that perform explicit or implicit commit or\nrollback. Support for these statements is not required by the SQL\nstandard, which states that each DBMS vendor may decide whether to\nallow them.\n\nStatements that return a result set can be used within a stored\nprocedcure but not within a stored function. This prohibition includes\nSELECT statements that do not have an INTO var_list clause and other\nstatements such as SHOW, EXPLAIN, and CHECK TABLE. For statements that\ncan be determined at function definition time to return a result set, a\nNot allowed to return a result set from a function error occurs\n(ER_SP_NO_RETSET). For statements that can be determined only at\nruntime to return a result set, a PROCEDURE %s can\'t return a result\nset in the given context error occurs (ER_SP_BADSELECT).\n\nUSE statements within stored routines are disallowed. When a routine is\ninvoked, an implicit USE db_name is performed (and undone when the\nroutine terminates). The causes the routine to have the given default\ndatabase while it executes. References to objects in databases other\nthan the routine default database should be qualified with the\nappropriate database name.\n\nFor additional information about statements that are not allowed in\nstored routines, see\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-program-restrictions.htm… information about invoking stored procedures from within programs\nwritten in a language that has a MySQL interface, see [HELP CALL].\n\nMySQL stores the sql_mode system variable setting that is in effect at\nthe time a routine is created, and always executes the routine with\nthis setting in force, regardless of the server SQL mode in effect when\nthe routine is invoked.\n\nThe switch from the SQL mode of the invoker to that of the routine\noccurs after evaluation of arguments and assignment of the resulting\nvalues to routine parameters. If you define a routine in strict SQL\nmode but invoke it in nonstrict mode, assignment of arguments to\nroutine parameters does not take place in strict mode. If you require\nthat expressions passed to a routine be assigned in strict SQL mode,\nyou should invoke the routine with strict mode in effect.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (300,20,'VARBINARY','VARBINARY(M)\n\nThe VARBINARY type is similar to the VARCHAR type, but stores binary\nbyte strings rather than nonbinary character strings.

(Bug#36763\n(http://bugs.mysql.com/36763)) However, it is still applied on\nreplication slaves using InnoDB in the manner described previously.\n\nThe count of rows affected by TRUNCATE TABLE is accurate only when it\nis mapped to a DELETE statement.\n\nFor other storage engines, TRUNCATE TABLE differs from DELETE in the\nfollowing ways in MySQL 5.1:\n\no Truncate operations drop and re-create the table, which is much\n faster than deleting rows one by one, particularly for large tables.\n\no Truncate operations cause an implicit commit.\n\no Truncation operations cannot be performed if the session holds an\n active table lock.\n\no Truncation operations do not return a meaningful value for the number\n of deleted rows. The usual result is "0 rows affected," which should\n be interpreted as "no information."\n\no As long as the table format file tbl_name.frm is valid, the table can\n be re-created as an empty table with TRUNCATE TABLE, even if the data\n or index files have become corrupted.\n\no The table handler does not remember the last used AUTO_INCREMENT\n value, but starts counting from the beginning. This is true even for\n MyISAM and InnoDB, which normally do not reuse sequence values.\n\no When used with partitioned tables, TRUNCATE TABLE preserves the\n partitioning; that is, the data and index files are dropped and\n re-created, while the partition definitions (.par) file is\n unaffected.\n\no Since truncation of a table does not make any use of DELETE, the\n TRUNCATE statement does not invoke ON DELETE triggers.\n\nTRUNCATE TABLE requires the DROP privilege as of MySQL 5.1.16.

The latter requires Perl and two Perl\nmodules (DBI and DBD:mysql) and works for MyISAM and ARCHIVE tables\nonly. With mysqldump, you can create SQL dumps on the master and pipe\n(or copy) these to a mysql client on the slave.

(spin_rounds\n divided by spin_waits provides the average round count.)\n\n o os_waits indicates the number of operating system waits. This\n occurs when the spinlock did not work (the mutex was not locked\n during the spinlock and it was necessary to yield to the operating\n system and wait).\n\n o os_yields indicates the number of times a the thread trying to lock\n a mutex gave up its timeslice and yielded to the operating system\n (on the presumption that allowing other threads to run will free\n the mutex so that it can be locked).\n\n o os_wait_times indicates the amount of time (in ms) spent in\n operating system waits, if the timed_mutexes system variable is 1\n (ON).

The line number may change\n depending on your version of MySQL.\n\no Status\n\n This field displays the same values as previously described (count,\n spin_waits, spin_rounds, os_waits, os_yields, os_wait_times), but\n only if UNIV_DEBUG was defined at MySQL compilation time (for\n example, in include/univ.h in the InnoDB part of the MySQL source\n tree). If UNIV_DEBUG was not defined, the statement displays only the\n os_waits value. In the latter case (without UNIV_DEBUG), the\n information on which the output is based is insufficient to\n distinguish regular mutexes and mutexes that protect rw-locks (which\n allow multiple readers or a single writer).

Plugin names are\nnot case sensitive. For maximal compatibility, plugin names should be\nlimited to ASCII letters, digits, and underscore, because they are used\nin C source files, shell command lines, M4 and Bourne shell scripts,\nand SQL environments.\n\nplugin_library is the name of the shared library that contains the\nplugin code. The name includes the file name extension (for example,\nlibmyplugin.so or libmyplugin.dylib).\n\nThe shared library must be located in the plugin directory (that is,\nthe directory named by the plugin_dir system variable). The library\nmust be in the plugin directory itself, not in a subdirectory. By\ndefault, plugin_dir is plugin directory under the directory named by\nthe pkglibdir configuration variable, but it can be changed by setting\nthe value of plugin_dir at server startup. For example, set its value\nin a my.cnf file:\n\n[mysqld]\nplugin_dir=/path/to/plugin/directory\n\nIf the value of plugin_dir is a relative path name, it is taken to be\nrelative to the MySQL base directory (the value of the basedir system\nvariable).\n\nINSTALL PLUGIN adds a line to the mysql.plugin table that describes the\nplugin. This table contains the plugin name and library file name.\n\nAs of MySQL 5.1.33, INSTALL PLUGIN causes the server to read option\n(my.cnf) files just as during server startup. This enables the plugin\nto pick up any relevant options from those files. It is possible to add\nplugin options to an option file even before loading a plugin (if the\nloose prefix is used). It is also possible to uninstall a plugin, edit\nmy.cnf, and install the plugin again. Restarting the plugin this way\nenables it to the new option values without a server restart.\n\nBefore MySQL 5.1.33, a plugin is started with each option set to its\ndefault value.\n\nINSTALL PLUGIN also loads and initializes the plugin code to make the\nplugin available for use. A plugin is initialized by executing its\ninitialization function, which handles any setup that the plugin must\nperform before it can be used.\n\nTo use INSTALL PLUGIN, you must have the INSERT privilege for the\nmysql.plugin table.\n\nAt server startup, the server loads and initializes any plugin that is\nlisted in the mysql.plugin table. This means that a plugin is installed\nwith INSTALL PLUGIN only once, not every time the server starts. Plugin\nloading at startup does not occur if the server is started with the\n--skip-grant-tables option.\n\nWhen the server shuts down, it executes the deinitialization function\nfor each plugin that is loaded so that the plugin has a change to\nperform any final cleanup.\n\nFor options that control individual plugin loading at server startup,\nsee http://dev.mysql.com/doc/refman/5.1/en/server-plugin-options.html.\nIf you need to load plugins for a single server startup when the\n--skip-grant-tables option is given (which tells the server not to read\nsystem tables), use the --plugin-load option.

The file name must be given as a literal string.\n\nLOAD DATA INFILE is the complement of SELECT ... INTO OUTFILE. (See\nhttp://dev.mysql.com/doc/refman/5.1/en/select.html.) To write data from\na table to a file, use SELECT ... INTO OUTFILE. To read the file back\ninto a table, use LOAD DATA INFILE. The syntax of the FIELDS and LINES\nclauses is the same for both statements. Both clauses are optional, but\nFIELDS must precede LINES if both are specified.\n\nFor more information about the efficiency of INSERT versus LOAD DATA\nINFILE and speeding up LOAD DATA INFILE, see\nhttp://dev.mysql.com/doc/refman/5.1/en/insert-speed.html.\n\nThe character set indicated by the character_set_database system\nvariable is used to interpret the information in the file. SET NAMES\nand the setting of character_set_client do not affect interpretation of\ninput. If the contents of the input file use a character set that\ndiffers from the default, it is usually preferable to specify the\ncharacter set of the file by using the CHARACTER SET clause, which is\navailable as of MySQL 5.1.17. A character set of binary specifies "no\nconversion."\n\nLOAD DATA INFILE interprets all fields in the file as having the same\ncharacter set, regardless of the data types of the columns into which\nfield values are loaded. For proper interpretation of file contents,\nyou must ensure that it was written with the correct character set. For\nexample, if you write a data file with mysqldump -T or by issuing a\nSELECT ... INTO OUTFILE statement in mysql, be sure to use a\n--default-character-set option with mysqldump or mysql so that output\nis written in the character set to be used when the file is loaded with\nLOAD DATA INFILE.\n\nNote that it is currently not possible to load data files that use the\nucs2, utf16, or utf32 character set.\n\nAs of MySQL 5.1.6, the character_set_filesystem system variable\ncontrols the interpretation of the file name.\n\nYou can also load data files by using the mysqlimport utility; it\noperates by sending a LOAD DATA INFILE statement to the server. The\n--local option causes mysqlimport to read data files from the client\nhost. You can specify the --compress option to get better performance\nover slow networks if the client and server support the compressed\nprotocol. See http://dev.mysql.com/doc/refman/5.1/en/mysqlimport.html.\n\nIf you use LOW_PRIORITY, execution of the LOAD DATA statement is\ndelayed until no other clients are reading from the table. This affects\nonly storage engines that use only table-level locking (MyISAM, MEMORY,\nMERGE).\n\nIf you specify CONCURRENT with a MyISAM table that satisfies the\ncondition for concurrent inserts (that is, it contains no free blocks\nin the middle), other threads can retrieve data from the table while\nLOAD DATA is executing. Using this option affects the performance of\nLOAD DATA a bit, even if no other thread is using the table at the same\ntime.\n\nCONCURRENT is not replicated when using statement-based replication;\nhowever, it is replicated when using row-based replication. See\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-features-load-data.…, for more information.\n\n*Note*: Prior to MySQL 5.1.23, LOAD DATA performed very poorly when\nimporting into partitioned tables. The statement now uses buffering to\nimprove performance; however, the buffer uses 130 KB memory per\npartition to achieve this. (Bug#26527 (http://bugs.mysql.com/26527))\n\nThe LOCAL keyword, if specified, is interpreted with respect to the\nclient end of the connection:\n\no If LOCAL is specified, the file is read by the client program on the\n client host and sent to the server. The file can be given as a full\n path name to specify its exact location. If given as a relative path\n name, the name is interpreted relative to the directory in which the\n client program was started.\n\no If LOCAL is not specified, the file must be located on the server\n host and is read directly by the server. The server uses the\n following rules to locate the file:\n\n o If the file name is an absolute path name, the server uses it as\n given.\n\n o If the file name is a relative path name with one or more leading\n components, the server searches for the file relative to the\n server\'s data directory.\n\n o If a file name with no leading components is given, the server\n looks for the file in the database directory of the default\n database.\n\nNote that, in the non-LOCAL case, these rules mean that a file named as\n./myfile.txt is read from the server\'s data directory, whereas the file\nnamed as myfile.txt is read from the database directory of the default\ndatabase. For example, if db1 is the default database, the following\nLOAD DATA statement reads the file data.txt from the database directory\nfor db1, even though the statement explicitly loads the file into a\ntable in the db2 database:\n\nLOAD DATA INFILE \'data.txt\' INTO TABLE db2.my_table;\n\nWindows path names are specified using forward slashes rather than\nbackslashes.

The default level is REPEATABLE\nREAD. For additional information about InnoDB record-level locks and\nhow it uses them to execute various types of statements, see\nhttp://dev.mysql.com/doc/refman/5.1/en/innodb-record-level-locks.html,… http://dev.mysql.com/doc/refman/5.1/en/innodb-locks-set.html.\n\nThe following list describes how MySQL supports the different\ntransaction levels:\n\no READ UNCOMMITTED\n\n SELECT statements are performed in a nonlocking fashion, but a\n possible earlier version of a row might be used. Thus, using this\n isolation level, such reads are not consistent. This is also called a\n "dirty read." Otherwise, this isolation level works like READ\n COMMITTED.\n\no READ COMMITTED\n\n A somewhat Oracle-like isolation level with respect to consistent\n (nonlocking) reads: Each consistent read, even within the same\n transaction, sets and reads its own fresh snapshot. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n InnoDB locks only index records, not the gaps before them, and thus\n allows the free insertion of new records next to locked records. For\n UPDATE and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition (such as\n WHERE id = 100), or a range-type search condition (such as WHERE id >\n 100). For a unique index with a unique search condition, InnoDB locks\n only the index record found, not the gap before it. For range-type\n searches, InnoDB locks the index range scanned, using gap locks or\n next-key (gap plus index-record) locks to block insertions by other\n sessions into the gaps covered by the range. This is necessary\n because "phantom rows" must be blocked for MySQL replication and\n recovery to work.\n\n *Note*: In MySQL 5.1, if the READ COMMITTED isolation level is used\n or the innodb_locks_unsafe_for_binlog system variable is enabled,\n there is no InnoDB gap locking except for foreign-key constraint\n checking and duplicate-key checking. Also, record locks for\n nonmatching rows are released after MySQL has evaluated the WHERE\n condition. As of MySQL 5.1, if you use READ COMMITTED or enable\n innodb_locks_unsafe_for_binlog, you must use row-based binary\n logging.\n\no REPEATABLE READ\n\n This is the default isolation level for InnoDB. For consistent reads,\n there is an important difference from the READ COMMITTED isolation\n level: All consistent reads within the same transaction read the\n snapshot established by the first read. This convention means that if\n you issue several plain (nonlocking) SELECT statements within the\n same transaction, these SELECT statements are consistent also with\n respect to each other. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n UPDATE, and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition, or a\n range-type search condition. For a unique index with a unique search\n condition, InnoDB locks only the index record found, not the gap\n before it. For other search conditions, InnoDB locks the index range\n scanned, using gap locks or next-key (gap plus index-record) locks to\n block insertions by other sessions into the gaps covered by the\n range.\n\no SERIALIZABLE\n\n This level is like REPEATABLE READ, but InnoDB implicitly converts\n all plain SELECT statements to SELECT ... LOCK IN SHARE MODE if\n autocommit is disabled. If autocommit is enabled, the SELECT is its\n own transaction. It therefore is known to be read only and can be\n serialized if performed as a consistent (nonlocking) read and need\n not block for other transactions. (This means that to force a plain\n SELECT to block if other transactions have modified the selected\n rows, you should disable autocommit.)\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (446,4,'CEILING','Syntax:\nCEILING(X)\n\nReturns the smallest integer value not less than X.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT CEILING(1.23);\n -> 2\nmysql> SELECT CEILING(-1.23);\n -> -1\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (447,4,'SIN','Syntax:\nSIN(X)\n\nReturns the sine of X, where X is given in radians.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT SIN(PI());\n -> 1.2246063538224e-16\nmysql> SELECT ROUND(SIN(PI()));\n -> 0\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (448,30,'DAYOFWEEK','Syntax:\nDAYOFWEEK(date)\n\nReturns the weekday index for date (1 = Sunday, 2 = Monday, ..., 7 =\nSaturday).

By default, the names of the columns retrieved by the SELECT\nstatement are used for the view column names. To define explicit names\nfor the view columns, the optional column_list clause can be given as a\nlist of comma-separated identifiers. The number of names in column_list\nmust be the same as the number of columns retrieved by the SELECT\nstatement.\n\n*Note*: Prior to MySQL 5.1.29, when you modify an existing view, the\ncurrent view definition is backed up and saved. It is stored in that\ntable\'s database directory, in a subdirectory named arc. The backup\nfile for a view v is named v.frm-00001. If you alter the view again,\nthe next backup is named v.frm-00002. The three latest view backup\ndefinitions are stored. Backed up view definitions are not preserved by\nmysqldump, or any other such programs, but you can retain them using a\nfile copy operation. However, they are not needed for anything but to\nprovide you with a backup of your previous view definition. It is safe\nto remove these backup definitions, but only while mysqld is not\nrunning. If you delete the arc subdirectory or its files while mysqld\nis running, you will receive an error the next time you try to alter\nthe view: mysql> ALTER VIEW v AS SELECT * FROM t; ERROR 6 (HY000):\nError on delete of \'.\\test\\arc/v.frm-0004\' (Errcode: 2)\n\nColumns retrieved by the SELECT statement can be simple references to\ntable columns. They can also be expressions that use functions,\nconstant values, operators, and so forth.\n\nUnqualified table or view names in the SELECT statement are interpreted\nwith respect to the default database. A view can refer to tables or\nviews in other databases by qualifying the table or view name with the\nproper database name.\n\nA view can be created from many kinds of SELECT statements. It can\nrefer to base tables or other views. It can use joins, UNION, and\nsubqueries. The SELECT need not even refer to any tables. The following\nexample defines a view that selects two columns from another table, as\nwell as an expression calculated from those columns:\n\nmysql> CREATE TABLE t (qty INT, price INT);\nmysql> INSERT INTO t VALUES(3, 50);\nmysql> CREATE VIEW v AS SELECT qty, price, qty*price AS value FROM t;\nmysql> SELECT * FROM v;\n+------+-------+-------+\n| qty | price | value |\n+------+-------+-------+\n| 3 | 50 | 150 |\n+------+-------+-------+\n\nA view definition is subject to the following restrictions:\n\no The SELECT statement cannot contain a subquery in the FROM clause.\n\no The SELECT statement cannot refer to system or user variables.\n\no Within a stored program, the definition cannot refer to program\n parameters or local variables.\n\no The SELECT statement cannot refer to prepared statement parameters.\n\no Any table or view referred to in the definition must exist. However,\n after a view has been created, it is possible to drop a table or view\n that the definition refers to. In this case, use of the view results\n in an error. To check a view definition for problems of this kind,\n use the CHECK TABLE statement.\n\no The definition cannot refer to a TEMPORARY table, and you cannot\n create a TEMPORARY view.\n\no Any tables named in the view definition must exist at definition\n time.\n\no You cannot associate a trigger with a view.\n\no As of MySQL 5.1.23, aliases for column names in the SELECT statement\n are checked against the maximum column length of 64 characters (not\n the maximum alias length of 256 characters).\n\nORDER BY is allowed in a view definition, but it is ignored if you\nselect from a view using a statement that has its own ORDER BY.\n\nFor other options or clauses in the definition, they are added to the\noptions or clauses of the statement that references the view, but the\neffect is undefined. For example, if a view definition includes a LIMIT\nclause, and you select from the view using a statement that has its own\nLIMIT clause, it is undefined which limit applies. This same principle\napplies to options such as ALL, DISTINCT, or SQL_SMALL_RESULT that\nfollow the SELECT keyword, and to clauses such as INTO, FOR UPDATE,\nLOCK IN SHARE MODE, and PROCEDURE.\n\nIf you create a view and then change the query processing environment\nby changing system variables, that may affect the results that you get\nfrom the view:\n\nmysql> CREATE VIEW v (mycol) AS SELECT \'abc\';\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> SET sql_mode = \'\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| mycol |\n+-------+\n1 row in set (0.01 sec)\n\nmysql> SET sql_mode = \'ANSI_QUOTES\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| abc |\n+-------+\n1 row in set (0.00 sec)\n\nThe DEFINER and SQL SECURITY clauses determine which MySQL account to\nuse when checking access privileges for the view when a statement is\nexecuted that references the view. They were addded in MySQL 5.1.2. The\nlegal SQL SECURITY characteristic values are DEFINER and INVOKER. These\nindicate that the required privileges must be held by the user who\ndefined or invoked the view, respectively. The default SQL SECURITY\nvalue is DEFINER.\n\nIf a user value is given for the DEFINER clause, it should be a MySQL\naccount in \'user_name\'@\'host_name\' format (the same format used in the\nGRANT statement). The user_name and host_name values both are required.\nThe definer can also be given as CURRENT_USER or CURRENT_USER(). The\ndefault DEFINER value is the user who executes the CREATE VIEW\nstatement. This is the same as specifying DEFINER = CURRENT_USER\nexplicitly.\n\nIf you specify the DEFINER clause, these rules determine the legal\nDEFINER user values:\n\no If you do not have the SUPER privilege, the only legal user value is\n your own account, either specified literally or by using\n CURRENT_USER. You cannot set the definer to some other account.\n\no If you have the SUPER privilege, you can specify any syntactically\n legal account name. If the account does not actually exist, a warning\n is generated.\n\no If the SQL SECURITY value is DEFINER but the definer account does not\n exist when the view is referenced, an error occurs.\n\nWithin a view definition, CURRENT_USER returns the view\'s DEFINER value\nby default as of MySQL 5.1.12. For older versions, and for views\ndefined with the SQL SECURITY INVOKER characteristic, CURRENT_USER\nreturns the account for the view\'s invoker. For information about user\nauditing within views, see\nhttp://dev.mysql.com/doc/refman/5.1/en/account-activity-auditing.html.… a stored routine that is defined with the SQL SECURITY DEFINER\ncharacteristic, CURRENT_USER returns the routine\'s DEFINER value. This\nalso affects a view defined within such a program, if the view\ndefinition contains a DEFINER value of CURRENT_USER.\n\nAs of MySQL 5.1.2 (when the DEFINER and SQL SECURITY clauses were\nimplemented), view privileges are checked like this:\n\no At view definition time, the view creator must have the privileges\n needed to use the top-level objects accessed by the view. For\n example, if the view definition refers to table columns, the creator\n must have privileges for the columns, as described previously. If the\n definition refers to a stored function, only the privileges needed to\n invoke the function can be checked. The privileges required when the\n function runs can be checked only as it executes: For different\n invocations of the function, different execution paths within the\n function might be taken.\n\no When a view is referenced, privileges for objects accessed by the\n view are checked against the privileges held by the view creator or\n invoker, depending on whether the SQL SECURITY characteristic is\n DEFINER or INVOKER, respectively.\n\no If reference to a view causes execution of a stored function,\n privilege checking for statements executed within the function depend\n on whether the function is defined with a SQL SECURITY characteristic\n of DEFINER or INVOKER. If the security characteristic is DEFINER, the\n function runs with the privileges of its creator. If the\n characteristic is INVOKER, the function runs with the privileges\n determined by the view\'s SQL SECURITY characteristic.\n\nPrior to MySQL 5.1.2 (before the DEFINER and SQL SECURITY clauses were\nimplemented), privileges required for objects used in a view are\nchecked at view creation time.\n\nExample: A view might depend on a stored function, and that function\nmight invoke other stored routines. For example, the following view\ninvokes a stored function f():\n\nCREATE VIEW v AS SELECT * FROM t WHERE t.id = f(t.name);\n\nSuppose that f() contains a statement such as this:\n\nIF name IS NULL then\n CALL p1();\nELSE\n CALL p2();\nEND IF;\n\nThe privileges required for executing statements within f() need to be\nchecked when f() executes. This might mean that privileges are needed\nfor p1() or p2(), depending on the execution path within f(). Those\nprivileges must be checked at runtime, and the user who must possess\nthe privileges is determined by the SQL SECURITY values of the view v\nand the function f().\n\nThe DEFINER and SQL SECURITY clauses for views are extensions to\nstandard SQL. In standard SQL, views are handled using the rules for\nSQL SECURITY INVOKER.\n\nIf you invoke a view that was created before MySQL 5.1.2, it is treated\nas though it was created with a SQL SECURITY DEFINER clause and with a\nDEFINER value that is the same as your account. However, because the\nactual definer is unknown, MySQL issues a warning. To make the warning\ngo away, it is sufficient to re-create the view so that the view\ndefinition includes a DEFINER clause.\n\nThe optional ALGORITHM clause is a MySQL extension to standard SQL. It\naffects how MySQL processes the view. ALGORITHM takes three values:\nMERGE, TEMPTABLE, or UNDEFINED. The default algorithm is UNDEFINED if\nno ALGORITHM clause is present. For more information, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-algorithms.html.\n\nSome views are updatable. That is, you can use them in statements such\nas UPDATE, DELETE, or INSERT to update the contents of the underlying\ntable. For a view to be updatable, there must be a one-to-one\nrelationship between the rows in the view and the rows in the\nunderlying table. There are also certain other constructs that make a\nview nonupdatable.\n\nThe WITH CHECK OPTION clause can be given for an updatable view to\nprevent inserts or updates to rows except those for which the WHERE\nclause in the select_statement is true.\n\nIn a WITH CHECK OPTION clause for an updatable view, the LOCAL and\nCASCADED keywords determine the scope of check testing when the view is\ndefined in terms of another view. The LOCAL keyword restricts the CHECK\nOPTION only to the view being defined. CASCADED causes the checks for\nunderlying views to be evaluated as well. When neither keyword is\ngiven, the default is CASCADED.\n\nFor more information about updatable views and the WITH CHECK OPTION\nclause, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-updatability.html.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-view.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-view.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (453,35,'TRIM','Syntax:\nTRIM([{BOTH | LEADING | TRAILING} [remstr] FROM] str), TRIM([remstr\nFROM] str)\n\nReturns the string str with all remstr prefixes or suffixes removed.

This is a common situation\nwhen you use MySQL for logging and you also periodically run SELECT and\nUPDATE statements that take a long time to complete.\n\nWhen a client uses INSERT DELAYED, it gets an okay from the server at\nonce, and the row is queued to be inserted when the table is not in use\nby any other thread.\n\nAnother major benefit of using INSERT DELAYED is that inserts from many\nclients are bundled together and written in one block. This is much\nfaster than performing many separate inserts.\n\nNote that INSERT DELAYED is slower than a normal INSERT if the table is\nnot otherwise in use. There is also the additional overhead for the\nserver to handle a separate thread for each table for which there are\ndelayed rows. This means that you should use INSERT DELAYED only when\nyou are really sure that you need it.\n\nThe queued rows are held only in memory until they are inserted into\nthe table. This means that if you terminate mysqld forcibly (for\nexample, with kill -9) or if mysqld dies unexpectedly, any queued rows\nthat have not been written to disk are lost.\n\nThere are some constraints on the use of DELAYED:\n\no INSERT DELAYED works only with MyISAM, MEMORY, ARCHIVE, and (as of\n MySQL 5.1.19) BLACKHOLE tables. For engines that do not support\n DELAYED, an error occurs.\n\no An error occurs for INSERT DELAYED if used with a table that has been\n locked with LOCK TABLES because the insert must be handled by a\n separate thread, not by the session that holds the lock.\n\no For MyISAM tables, if there are no free blocks in the middle of the\n data file, concurrent SELECT and INSERT statements are supported.\n Under these circumstances, you very seldom need to use INSERT DELAYED\n with MyISAM.\n\no INSERT DELAYED should be used only for INSERT statements that specify\n value lists. The server ignores DELAYED for INSERT ... SELECT or\n INSERT ... ON DUPLICATE KEY UPDATE statements.\n\no Because the INSERT DELAYED statement returns immediately, before the\n rows are inserted, you cannot use LAST_INSERT_ID() to get the\n AUTO_INCREMENT value that the statement might generate.\n\no DELAYED rows are not visible to SELECT statements until they actually\n have been inserted.\n\no INSERT DELAYED is treated as a normal INSERT if the statement inserts\n multiple rows and binary logging is enabled and the global logging\n format is to use statement-based logging (binlog_format is set to\n STATEMENT). This restriction does not apply to row-based binary\n logging.\n\no DELAYED is ignored on slave replication servers, so that INSERT\n DELAYED is treated as a normal INSERT on slaves. This is because\n DELAYED could cause the slave to have different data than the master.\n\no Pending INSERT DELAYED statements are lost if a table is write locked\n and ALTER TABLE is used to modify the table structure.\n\no INSERT DELAYED is not supported for views.\n\no INSERT DELAYED is not supported for partitioned tables.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/insert-delayed.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/insert-delayed.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (483,25,'SHOW PROFILE','Syntax:\nSHOW PROFILES\n\nThe SHOW PROFILE statement display profiling information that indicates\nresource usage for statements executed during the course of the current\nsession.

This is a very convenient way to\nget backups if you have a file system such as Veritas that can take\nsnapshots in time.)\n\nThe following discussion applies only to non-TEMPORARY tables. LOCK\nTABLES is allowed (but ignored) for a TEMPORARY table. The table can be\naccessed freely by the session within which it was created, regardless\nof what other locking may be in effect. No lock is necessary because no\nother session can see the table.\n\nThe following general rules apply to acquisition and release of locks\nby a given thread:\n\no Table locks are acquired with LOCK TABLES.\n\no If the LOCK TABLES statement must wait due to locks held by other\n threads on any of the tables, it blocks until all locks can be\n acquired.\n\no Table locks are released explicitly with UNLOCK TABLES.\n\no Table locks are released implicitly under these conditions:\n\n o LOCK TABLES releases any table locks currently held by the thread\n before acquiring new locks.\n\n o Beginning a transaction (for example, with START TRANSACTION)\n implicitly performs an UNLOCK TABLES. (Additional information about\n the interaction between table locking and transactions is given\n later in this section.)\n\n o If a client connection drops, the server releases table locks held\n by the client. If the client reconnects, the locks will no longer\n be in effect. In addition, if the client had an active transaction,\n the server rolls back the transaction upon disconnect, and if\n reconnect occurs, the new session begins with autocommit enabled.\n For this reason, clients may wish to disable auto-reconnect. With\n auto-reconnect in effect, the client is not notified if reconnect\n occurs but any table locks or current transaction will have been\n lost. With auto-reconnect disabled, if the connection drops, an\n error occurs for the next statement issued. The client can detect\n the error and take appropriate action such as reacquiring the locks\n or redoing the transaction. See\n http://dev.mysql.com/doc/refman/5.1/en/auto-reconnect.html.\n\n*Note*: If you use ALTER TABLE on a locked table, it may become\nunlocked. See\nhttp://dev.mysql.com/doc/refman/5.1/en/alter-table-problems.html.\n\nA table lock protects only against inappropriate reads or writes by\nother clients.

For\n more information, see\n http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html.\n\no A natural language search interprets the search string as a phrase in\n natural human language (a phrase in free text).

Full-text searches are natural language searches if the IN\n NATURAL LANGUAGE MODE modifier is given or if no modifier is given.\n\no A query expansion search is a modification of a natural language\n search. The search string is used to perform a natural language\n search. Then words from the most relevant rows returned by the search\n are added to the search string and the search is done again.

MASTER_SSL_VERIFY_SERVER_CERT was\nadded in MySQL 5.1.18. It is used as described for the\n--ssl-verify-server-cert option in\nhttp://dev.mysql.com/doc/refman/5.1/en/ssl-options.html.\n\nMASTER_CONN… specifies how many seconds to wait between connect\nretries. The default is 60. The number of reconnection attempts is\nlimited by the --master-retry-count server option; for more\ninformation, see\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-options.html.\n\nThe SSL options (MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH,\nMASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER), and\nMASTER_SSL_VERIFY_SERVER_CERT can be changed even on slaves that are\ncompiled without SSL support. They are saved to the master.info file,\nbut are ignored unless you use a server that has SSL support enabled.\n\nIf you don\'t specify a given parameter, it keeps its old value, except\nas indicated in the following discussion. For example, if the password\nto connect to your MySQL master has changed, you just need to issue\nthese statements to tell the slave about the new password:\n\nSTOP SLAVE; -- if replication was running\nCHANGE MASTER TO MASTER_PASSWORD=\'new3cret\';\nSTART SLAVE; -- if you want to restart replication\n\nThere is no need to specify the parameters that do not change (host,\nport, user, and so forth).\n\nMASTER_HOST and MASTER_PORT are the host name (or IP address) of the\nmaster host and its TCP/IP port.\n\nThe next two options are available only in MySQL Cluster NDB 6.3 and\n6.4; they are not supported in mainline MySQL 5.1:\n\no MASTER_BIND is for use on replication slaves having multiple network\n interfaces, and determines which of the slave\'s network interfaces is\n chosen for connecting to the master. It is also possible to determine\n which network interface is to be used in such cases by starting the\n slave mysqld process with the --master-bind option.\n\n The ability to bind a replication slave to specific network interface\n was added in MySQL Cluster NDB 6.3.4.\n\no MASTER_HEARTBEAT_PERIOD is used to set the interval in seconds\n between replication heartbeats. Whenever the master\'s binlog is\n updated with an event, the waiting period for the next heartbeat is\n reset. interval is a decimal value having the range 0 to 4294967\n seconds and a resolution to hundredths of a second; the smallest\n nonzero value is 0.001. Heartbeats are sent by the master only if\n there are no unsent events in the binlog file for a period longer\n than interval.\n\n Setting interval to 0 disables heartbeats altogether. The default\n value for interval is equal to the value of slave_net_timeout divided\n by 2.\n\n *Note*: Setting @@global.slave_net_timeout to a value less than that\n of the current heartbeat interval results in a warning being issued.\n\n Issuing RESET SLAVE resets the heartbeat interval to the default.\n\n MASTER_HEARTBEAT_PERIOD was added in MySQL Cluster NDB 6.3.4.\n\n*Note*: Replication cannot use Unix socket files. You must be able to\nconnect to the master MySQL server using TCP/IP.\n\nIf you specify MASTER_HOST or MASTER_PORT, the slave assumes that the\nmaster server is different from before (even if you specify a host or\nport value that is the same as the current value.) In this case, the\nold values for the master binary log name and position are considered\nno longer applicable, so if you do not specify MASTER_LOG_FILE and\nMASTER_LOG_POS in the statement, MASTER_LOG_FILE=\'\' and\nMASTER_LOG_POS=4 are silently appended to it.\n\nSetting MASTER_HOST=\'\' --- that is, setting its value explicitly to an\nempty string --- is not the same as not setting it at all. Setting this\noption to an empty string causes START SLAVE subsequently to fail. This\nissue is addressed in MySQL 6.0. (Bug#28796\n(http://bugs.mysql.com/28796))\n\nMASTER_LOG_FILE and MASTER_LOG_POS are the coordinates at which the\nslave I/O thread should begin reading from the master the next time the\nthread starts. If you specify either of them, you cannot specify\nRELAY_LOG_FILE or RELAY_LOG_POS. If neither of MASTER_LOG_FILE or\nMASTER_LOG_POS are specified, the slave uses the last coordinates of\nthe slave SQL thread before CHANGE MASTER TO was issued. This ensures\nthat there is no discontinuity in replication, even if the slave SQL\nthread was late compared to the slave I/O thread, when you merely want\nto change, say, the password to use.\n\nCHANGE MASTER TO deletes all relay log files and starts a new one,\nunless you specify RELAY_LOG_FILE or RELAY_LOG_POS. In that case, relay\nlogs are kept; the relay_log_purge global variable is set silently to\n0.\n\nCHANGE MASTER TO is useful for setting up a slave when you have the\nsnapshot of the master and have recorded the log and the offset\ncorresponding to it. After loading the snapshot into the slave, you can\nrun CHANGE MASTER TO MASTER_LOG_FILE=\'log_name_on_master\',\nMASTER_LOG_POS=log_offset_on_master on the slave.\n\nThe following example changes the master and master\'s binary log\ncoordinates. This is used when you want to set up the slave to\nreplicate the master:\n\nCHANGE MASTER TO\n MASTER_HOST=\'master2.mycompany.com\',\n MASTER_USER=\'replication\',\n MASTER_PASSWORD=\'bigs3cret\',\n MASTER_PORT=3306,\n MASTER_LOG_FILE=\'master2-bin.001\',\n MASTER_LOG_POS=4,\n MASTER_CONNECT_RETRY=10;\n\nThe next example shows an operation that is less frequently employed.\nIt is used when the slave has relay logs that you want it to execute\nagain for some reason. To do this, the master need not be reachable.\nYou need only use CHANGE MASTER TO and start the SQL thread (START\nSLAVE SQL_THREAD):\n\nCHANGE MASTER TO\n RELAY_LOG_FILE=\'slave-relay-bin.006\',\n RELAY_LOG_POS=4025;\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (184,37,'DROP DATABASE','Syntax:\nDROP {DATABASE | SCHEMA} [IF EXISTS] db_name\n\nDROP DATABASE drops all tables in the database and deletes the\ndatabase.

For rules covering the naming\nof tablespaces, see\nhttp://dev.mysql.com/doc/refman/5.1/en/identifiers.html.\n\n*Note*: All MySQL Cluster Disk Data objects share the same namespace.\nThis means that each Disk Data object must be uniquely named (and not\nmerely each Disk Data object of a given type). For example, you cannot\nhave a tablespace and a log file group with the same name, or a\ntablespace and a data file with the same name.\n\nPrior to MySQL Cluster NDB 6.2.17, 6.3.23, and 6.4.3, path and file\nnames for data files could not be longer than 128 characters.\n(Bug#31770 (http://bugs.mysql.com/31770))\n\nA log file group of one or more UNDO log files must be assigned to the\ntablespace to be created with the USE LOGFILE GROUP clause.\nlogfile_group must be an existing log file group created with CREATE\nLOGFILE GROUP (see\nhttp://dev.mysql.com/doc/refman/5.1/en/create-logfile-group.html).\nMu… tablespaces may use the same log file group for UNDO logging.\n\nThe EXTENT_SIZE sets the size, in bytes, of the extents used by any\nfiles belonging to the tablespace. The default value is 1M. The minimum\nsize is 32K, and theoretical maximum is 2G, although the practical\nmaximum size depends on a number of factors. In most cases, changing\nthe extent size does not have any measurable effect on performance, and\nthe default value is recommended for all but the most unusual\nsituations.\n\nAn extent is a unit of disk space allocation. One extent is filled with\nas much data as that extent can contain before another extent is used.\nIn theory, up to 65,535 (64K) extents may used per data file; however,\nthe recommended maximum is 32,768 (32K). The recommended maximum size\nfor a single data file is 32G --- that is, 32K extents x 1 MB per\nextent. In addition, once an extent is allocated to a given partition,\nit cannot be used to store data from a different partition; an extent\ncannot store data from more than one partition. This means, for example\nthat a tablespace having a single datafile whose INITIAL_SIZE is 256 MB\nand whose EXTENT_SIZE is 128M has just two extents, and so can be used\nto store data from at most two different disk data table partitions.\n\nYou can see how many extents remain free in a given data file by\nquerying the INFORMATION_SCHEMA.FILES table, and so derive an estimate\nfor how much space remains free in the file. For further discussion and\nexamples, see http://dev.mysql.com/doc/refman/5.1/en/files-table.html.\n\nThe INITIAL_SIZE parameter sets the data file\'s total size in bytes.\nOnce the file has been created, its size cannot be changed; however,\nyou can add more data files to the tablespace using ALTER TABLESPACE\n... ADD DATAFILE. See [HELP ALTER TABLESPACE].\n\nINITIAL_SIZE is optional; its default value is 128M.\n\nOn 32-bit systems, the maximum supported value for INITIAL_SIZE is 4G.\n(Bug#29186 (http://bugs.mysql.com/29186))\n\nWhen setting EXTENT_SIZE or INITIAL_SIZE (either or both), you may\noptionally follow the number with a one-letter abbreviation for an\norder of magnitude, similar to those used in my.cnf. Generally, this is\none of the letters M (for megabytes) or G (for gigabytes).\n\nAUTOEXTEND_SIZE, MAX_SIZE, NODEGROUP, WAIT, and COMMENT are parsed but\nignored, and so have no effect in MySQL 5.1. These options are intended\nfor future expansion.\n\nThe ENGINE parameter determines the storage engine which uses this\ntablespace, with engine_name being the name of the storage engine. In\nMySQL 5.1, engine_name must be one of the values NDB or NDBCLUSTER.\n\nWhen CREATE TABLESPACE is used with ENGINE = NDB, a tablespace and\nassociated data file are created on each Cluster data node. You can\nverify that the data files were created and obtain information about\nthem by querying the INFORMATION_SCHEMA.FILES table. For example:\n\nmysql> SELECT LOGFILE_GROUP_NAME, FILE_NAME, EXTRA \n -> FROM INFORMATION_SCHEMA.FILES\n -> WHERE TABLESPACE_NAME = \'newts\' AND FILE_TYPE = \'DATAFILE\';\n+--------------------+-------------+----------------+\n| LOGFILE_GROUP_NAME | FILE_NAME | EXTRA |\n+--------------------+-------------+----------------+\n| lg_3 | newdata.dat | CLUSTER_NODE=3 |\n| lg_3 | newdata.dat | CLUSTER_NODE=4 |\n+--------------------+-------------+----------------+\n2 rows in set (0.01 sec)\n\n(See http://dev.mysql.com/doc/refman/5.1/en/files-table.html.)\n\nCREATE TABLESPACE was added in MySQL 5.1.6.

By default, a routine is\nassociated with the default database. To associate the routine\nexplicitly with a given database, specify the name as db_name.sp_name\nwhen you create it.\n\nThe CREATE FUNCTION statement is also used in MySQL to support UDFs\n(user-defined functions). See\nhttp://dev.mysql.com/doc/refman/5.1/en/adding-functions.html. A UDF can\nbe regarded as an external stored function. However, do note that\nstored functions share their namespace with UDFs. See\nhttp://dev.mysql.com/doc/refman/5.1/en/function-resolution.html, for\nthe rules describing how the server interprets references to different\nkinds of functions.\n\nWhen the routine is invoked, an implicit USE db_name is performed (and\nundone when the routine terminates). The causes the routine to have the\ngiven default database while it executes. USE statements within stored\nroutines are disallowed.\n\nWhen a stored function has been created, you invoke it by referring to\nit in an expression. The function returns a value during expression\nevaluation. When a stored procedure has been created, you invoke it by\nusing the CALL statement (see [HELP CALL]).\n\nTo execute the CREATE PROCEDURE or CREATE FUNCTION statement, it is\nnecessary to have the CREATE ROUTINE privilege. By default, MySQL\nautomatically grants the ALTER ROUTINE and EXECUTE privileges to the\nroutine creator. See also\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.htm… binary logging is enabled, the CREATE FUNCTION statement might also\nrequire the SUPER privilege, as described in\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-logging.html.\n\… DEFINER and SQL SECURITY clauses specify the security context to be\nused when checking access privileges at routine execution time, as\ndescribed later.\n\nIf the routine name is the same as the name of a built-in SQL function,\nyou must use a space between the name and the following parenthesis\nwhen defining the routine, or a syntax error occurs. This is also true\nwhen you invoke the routine later. For this reason, we suggest that it\nis better to avoid re-using the names of existing SQL functions for\nyour own stored routines.\n\nThe IGNORE_SPACE SQL mode applies to built-in functions, not to stored\nroutines. It is always allowable to have spaces after a routine name,\nregardless of whether IGNORE_SPACE is enabled.\n\nThe parameter list enclosed within parentheses must always be present.\nIf there are no parameters, an empty parameter list of () should be\nused. Parameter names are not case sensitive.\n\nEach parameter can be declared to use any valid data type, except that\nthe COLLATE attribute cannot be used.\n\nEach parameter is an IN parameter by default. To specify otherwise for\na parameter, use the keyword OUT or INOUT before the parameter name.\n\n*Note*: Specifying a parameter as IN, OUT, or INOUT is valid only for a\nPROCEDURE. (FUNCTION parameters are always regarded as IN parameters.)\n\nAn IN parameter passes a value into a procedure. The procedure might\nmodify the value, but the modification is not visible to the caller\nwhen the procedure returns. An OUT parameter passes a value from the\nprocedure back to the caller. Its initial value is NULL within the\nprocedure, and its value is visible to the caller when the procedure\nreturns. An INOUT parameter is initialized by the caller, can be\nmodified by the procedure, and any change made by the procedure is\nvisible to the caller when the procedure returns.\n\nFor each OUT or INOUT parameter, pass a user-defined variable in the\nCALL statement that invokes the procedure so that you can obtain its\nvalue when the procedure returns. If you are calling the procedure from\nwithin another stored procedure or function, you can also pass a\nroutine parameter or local routine variable as an IN or INOUT\nparameter.\n\nThe RETURNS clause may be specified only for a FUNCTION, for which it\nis mandatory. It indicates the return type of the function, and the\nfunction body must contain a RETURN value statement. If the RETURN\nstatement returns a value of a different type, the value is coerced to\nthe proper type. For example, if a function specifies an ENUM or SET\nvalue in the RETURNS clause, but the RETURN statement returns an\ninteger, the value returned from the function is the string for the\ncorresponding ENUM member of set of SET members.\n\nThe routine_body consists of a valid SQL procedure statement. This can\nbe a simple statement such as SELECT or INSERT, or it can be a compound\nstatement written using BEGIN and END. Compound statements can contain\ndeclarations, loops, and other control structure statements. The syntax\nfor these statements is described in\nhttp://dev.mysql.com/doc/refman/5.1/en/sql-syntax-compound-statements.h… allows routines to contain DDL statements, such as CREATE and\nDROP. MySQL also allows stored procedures (but not stored functions) to\ncontain SQL transaction statements such as COMMIT. Stored functions may\nnot contain statements that perform explicit or implicit commit or\nrollback. Support for these statements is not required by the SQL\nstandard, which states that each DBMS vendor may decide whether to\nallow them.\n\nStatements that return a result set cannot be used within a stored\nfunction. This includes SELECT statements that do not have an INTO\nvar_list clause and other statements such as SHOW, EXPLAIN, and CHECK\nTABLE. For statements that can be determined at function definition\ntime to return a result set, a Not allowed to return a result set from\na function error occurs (ER_SP_NO_RETSET). For statements that can be\ndetermined only at runtime to return a result set, a PROCEDURE %s can\'t\nreturn a result set in the given context error occurs\n(ER_SP_BADSELECT).\n\nFor additional information about statements that are not allowed in\nstored routines, see\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-program-restrictions.htm… following example shows a simple stored procedure that uses an OUT\nparameter:\n\nmysql> delimiter //\n\nmysql> CREATE PROCEDURE simpleproc (OUT param1 INT)\n -> BEGIN\n -> SELECT COUNT(*) INTO param1 FROM t;\n -> END;\n -> //\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> delimiter ;\n\nmysql> CALL simpleproc(@a);\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT @a;\n+------+\n| @a |\n+------+\n| 3 |\n+------+\n1 row in set (0.00 sec)\n\nThe example uses the mysql client delimiter command to change the\nstatement delimiter from ; to // while the procedure is being defined.\nThis allows the ; delimiter used in the procedure body to be passed\nthrough to the server rather than being interpreted by mysql itself.\nSee\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-defini… information about invoking stored procedures from within programs\nwritten in a language that has a MySQL interface, see [HELP CALL].\n\nThe following example function takes a parameter, performs an operation\nusing an SQL function, and returns the result. In this case, it is\nunnecessary to use delimiter because the function definition contains\nno internal ; statement delimiters:\n\nmysql> CREATE FUNCTION hello (s CHAR(20))\nmysql> RETURNS CHAR(50) DETERMINISTIC\n -> RETURN CONCAT(\'Hello, \',s,\'!\');\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT hello(\'world\');\n+----------------+\n| hello(\'world\') |\n+----------------+\n| Hello, world! |\n+----------------+\n1 row in set (0.00 sec)\n\nMySQL stores the sql_mode system variable setting that is in effect at\nthe time a routine is created, and always executes the routine with\nthis setting in force, regardless of the server SQL mode in effect when\nthe routine is invoked.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (299,20,'VARBINARY','VARBINARY(M)\n\nThe VARBINARY type is similar to the VARCHAR type, but stores binary\nbyte strings rather than non-binary character strings.

Logically, this is\nequivalent to a DELETE statement that deletes all rows, but there are\npractical differences under some circumstances.\n\nFor an InnoDB table, InnoDB processes TRUNCATE TABLE by deleting rows\none by one if there are any FOREIGN KEY constraints that reference the\ntable. If there are no FOREIGN KEY constraints, InnoDB performs fast\ntruncation by dropping the original table and creating an empty one\nwith the same definition, which is much faster than deleting rows one\nby one. The AUTO_INCREMENT counter is reset by TRUNCATE TABLE,\nregardless of whether there is a FOREIGN KEY constraint.\n\nIn the case that FOREIGN KEY constraints reference the table, InnoDB\ndeletes rows one by one and processes the constraints on each one. If\nthe FOREIGN KEY constraint specifies DELETE CASCADE, rows from the\nchild (referenced) table are deleted, and the truncated table becomes\nempty. If the FOREIGN KEY constraint does not specify CASCADE, the\nTRUNCATE statement deletes rows one by one and stops if it encounters a\nparent row that is referenced by the child, returning this error:\n\nERROR 1451 (23000): Cannot delete or update a parent row: a foreign\nkey constraint fails (`test`.`child`, CONSTRAINT `child_ibfk_1`\nFOREIGN KEY (`parent_id`) REFERENCES `parent` (`id`))\n\nThis is the same as a DELETE statement with no WHERE clause.\n\nBeginning with MySQL 5.1.32, TRUNCATE is treated for purposes of binary\nlogging and replication as DROP TABLE followed by CREATE TABLE --- that\nis, as DDL rather than DML. This is due to the fact that, when using\nInnoDB and other transactional storage engines where the transaction\nisolation level does not allow for statement-based logging (READ\nCOMMITTED or READ UNCOMMITTED), the statement was not logged and\nreplicated when using STATEMENT or MIXED logging mode. (Bug#36763\n(http://bugs.mysql.com/36763)) However, it is still applied on\nreplication slaves using InnoDB in the manner described previously.\n\nThe count of rows affected by TRUNCATE TABLE is accurate only when it\nis mapped to a DELETE statement.\n\nFor other storage engines, TRUNCATE TABLE differs from DELETE in the\nfollowing ways in MySQL 5.1:\n\no Truncate operations drop and re-create the table, which is much\n faster than deleting rows one by one, particularly for large tables.\n\no Truncate operations are not transaction-safe; an error occurs when\n attempting one in the course of an active transaction or active table\n lock.\n\no Truncation operations do not return the number of deleted rows.\n\no As long as the table format file tbl_name.frm is valid, the table can\n be re-created as an empty table with TRUNCATE TABLE, even if the data\n or index files have become corrupted.\n\no The table handler does not remember the last used AUTO_INCREMENT\n value, but starts counting from the beginning. This is true even for\n MyISAM and InnoDB, which normally do not reuse sequence values.\n\no When used with partitioned tables, TRUNCATE TABLE preserves the\n partitioning; that is, the data and index files are dropped and\n re-created, while the partition definitions (.par) file is\n unaffected.\n\no Since truncation of a table does not make any use of DELETE, the\n TRUNCATE statement does not invoke ON DELETE triggers.\n\nTRUNCATE TABLE requires the DROP privilege as of MySQL 5.1.16.

(spin_rounds\n divided by spin_waits provides the average round count.)\n\n o os_waits indicates the number of operating system waits. This\n occurs when the spinlock did not work (the mutex was not locked\n during the spinlock and it was necessary to yield to the operating\n system and wait).\n\n o os_yields indicates the number of times a the thread trying to lock\n a mutex gave up its timeslice and yielded to the operating system\n (on the presumption that allowing other threads to run will free\n the mutex so that it can be locked).\n\n o os_wait_times indicates the amount of time (in ms) spent in\n operating system waits, if the timed_mutexes system variable is 1\n (ON). If timed_mutexes is 0 (OFF), timing is disabled, so\n os_wait_times is 0. timed_mutexes is off by default.\n\nFrom MySQL 5.1.15 on, the statement displays the following output\nfields:\n\no Type\n\n Always InnoDB.\n\no Name\n\n The source file where the mutex is implemented, and the line number\n in the file where the mutex is created. The line number may change\n depending on your version of MySQL.\n\no Status\n\n This field displays the same values as previously described (count,\n spin_waits, spin_rounds, os_waits, os_yields, os_wait_times), but\n only if UNIV_DEBUG was defined at MySQL compilation time (for\n example, in include/univ.h in the InnoDB part of the MySQL source\n tree). If UNIV_DEBUG was not defined, the statement displays only the\n os_waits value. In the latter case (without UNIV_DEBUG), the\n information on which the output is based is insufficient to\n distinguish regular mutexes and mutexes that protect rw-locks (which\n allow multiple readers or a single writer).

For maximal compatibility, plugin names should be\nlimited to ASCII letters, digits, and underscore, because they are used\nin C source files, shell command lines, M4 and Bourne shell scripts,\nand SQL environments.\n\nplugin_library is the name of the shared library that contains the\nplugin code. The name includes the file name extension (for example,\nlibmyplugin.so or libmyplugin.dylib).\n\nThe shared library must be located in the plugin directory (that is,\nthe directory named by the plugin_dir system variable). The library\nmust be in the plugin directory itself, not in a subdirectory. By\ndefault, plugin_dir is plugin directory under the directory named by\nthe pkglibdir configuration variable, but it can be changed by setting\nthe value of plugin_dir at server startup. For example, set its value\nin a my.cnf file:\n\n[mysqld]\nplugin_dir=/path/to/plugin/directory\n\nIf the value of plugin_dir is a relative path name, it is taken to be\nrelative to the MySQL base directory (the value of the basedir system\nvariable).\n\nINSTALL PLUGIN adds a line to the mysql.plugin table that describes the\nplugin. This table contains the plugin name and library file name.\n\nAs of MySQL 5.1.33, INSTALL PLUGIN causes the server to read option\n(my.cnf) files just as during server startup. This enables the plugin\nto pick up any relevant options from those files. It is possible to add\nplugin options to an option file even before loading a plugin (if the\nloose prefix is used). It is also possible to uninstall a plugin, edit\nmy.cnf, and install the plugin again. Restarting the plugin this way\nenables it to the new option values without a server restart.\n\nBefore MySQL 5.1.33, a plugin is started with each option set to its\ndefault value.\n\nINSTALL PLUGIN also loads and initializes the plugin code to make the\nplugin available for use. A plugin is initialized by executing its\ninitialization function, which handles any setup that the plugin must\nperform before it can be used.\n\nTo use INSTALL PLUGIN, you must have the INSERT privilege for the\nmysql.plugin table.\n\nAt server startup, the server loads and initializes any plugin that is\nlisted in the mysql.plugin table.

To write data from\na table to a file, use SELECT ... INTO OUTFILE. To read the file back\ninto a table, use LOAD DATA INFILE. The syntax of the FIELDS and LINES\nclauses is the same for both statements. Both clauses are optional, but\nFIELDS must precede LINES if both are specified.\n\nFor more information about the efficiency of INSERT versus LOAD DATA\nINFILE and speeding up LOAD DATA INFILE, see\nhttp://dev.mysql.com/doc/refman/5.1/en/insert-speed.html.\n\nThe character set indicated by the character_set_database system\nvariable is used to interpret the information in the file. SET NAMES\nand the setting of character_set_client do not affect interpretation of\ninput. If the contents of the input file use a character set that\ndiffers from the default, it is usually preferable to specify the\ncharacter set of the file by using the CHARACTER SET clause, which is\navailable as of MySQL 5.1.17.\n\nLOAD DATA INFILE interprets all fields in the file as having the same\ncharacter set, regardless of the data types of the columns into which\nfield values are loaded. For proper interpretation of file contents,\nyou must ensure that it was written with the correct character set. For\nexample, if you write a data file with mysqldump -T or by issuing a\nSELECT ... INTO OUTFILE statement in mysql, be sure to use a\n--default-character-set option with mysqldump or mysql so that output\nis written in the character set to be used when the file is loaded with\nLOAD DATA INFILE.\n\nNote that it is currently not possible to load data files that use the\nucs2, utf16, or utf32 character set.\n\nAs of MySQL 5.1.6, the character_set_filesystem system variable\ncontrols the interpretation of the file name.\n\nYou can also load data files by using the mysqlimport utility; it\noperates by sending a LOAD DATA INFILE statement to the server. The\n--local option causes mysqlimport to read data files from the client\nhost. You can specify the --compress option to get better performance\nover slow networks if the client and server support the compressed\nprotocol. See http://dev.mysql.com/doc/refman/5.1/en/mysqlimport.html.\n\nIf you use LOW_PRIORITY, execution of the LOAD DATA statement is\ndelayed until no other clients are reading from the table. This affects\nonly storage engines that use only table-level locking (MyISAM, MEMORY,\nMERGE).\n\nIf you specify CONCURRENT with a MyISAM table that satisfies the\ncondition for concurrent inserts (that is, it contains no free blocks\nin the middle), other threads can retrieve data from the table while\nLOAD DATA is executing. Using this option affects the performance of\nLOAD DATA a bit, even if no other thread is using the table at the same\ntime.\n\nCONCURRENT is not replicated when using statement-based replication;\nhowever, it is replicated when using row-based replication. See\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-features-load-data.…, for more information.\n\n*Note*: Prior to MySQL 5.1.23, LOAD DATA performed very poorly when\nimporting into partitioned tables. The statement now uses buffering to\nimprove performance; however, the buffer uses 130 KB memory per\npartition to achieve this. (Bug#26527 (http://bugs.mysql.com/26527))\n\nThe LOCAL keyword, if specified, is interpreted with respect to the\nclient end of the connection:\n\no If LOCAL is specified, the file is read by the client program on the\n client host and sent to the server. The file can be given as a full\n path name to specify its exact location. If given as a relative path\n name, the name is interpreted relative to the directory in which the\n client program was started.\n\no If LOCAL is not specified, the file must be located on the server\n host and is read directly by the server. The server uses the\n following rules to locate the file:\n\n o If the file name is an absolute path name, the server uses it as\n given.\n\n o If the file name is a relative path name with one or more leading\n components, the server searches for the file relative to the\n server\'s data directory.\n\n o If a file name with no leading components is given, the server\n looks for the file in the database directory of the default\n database.\n\nNote that, in the non-LOCAL case, these rules mean that a file named as\n./myfile.txt is read from the server\'s data directory, whereas the file\nnamed as myfile.txt is read from the database directory of the default\ndatabase.

For example, to set\nthe default isolation level to REPEATABLE READ, use these lines in the\n[mysqld] section of an option file:\n\n[mysqld]\ntransaction-isolation = REPEATABLE-READ\n\nTo determine the global and session transaction isolation levels at\nruntime, check the value of the tx_isolation system variable:\n\nSELECT @@GLOBAL.tx_isolation, @@tx_isolation;\n\nInnoDB supports each of the translation isolation levels described here\nusing different locking strategies. The default level is REPEATABLE\nREAD. For additional information about InnoDB record-level locks and\nhow it uses them to execute various types of statements, see\nhttp://dev.mysql.com/doc/refman/5.1/en/innodb-record-level-locks.html,… http://dev.mysql.com/doc/refman/5.1/en/innodb-locks-set.html.\n\nThe following list describes how MySQL supports the different\ntransaction levels:\n\no READ UNCOMMITTED\n\n SELECT statements are performed in a non-locking fashion, but a\n possible earlier version of a row might be used. Thus, using this\n isolation level, such reads are not consistent. This is also called a\n "dirty read." Otherwise, this isolation level works like READ\n COMMITTED.\n\no READ COMMITTED\n\n A somewhat Oracle-like isolation level with respect to consistent\n (non-locking) reads: Each consistent read, even within the same\n transaction, sets and reads its own fresh snapshot. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n InnoDB locks only index records, not the gaps before them, and thus\n allows the free insertion of new records next to locked records. For\n UPDATE and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition (such as\n WHERE id = 100), or a range-type search condition (such as WHERE id >\n 100). For a unique index with a unique search condition, InnoDB locks\n only the index record found, not the gap before it. For range-type\n searches, InnoDB locks the index range scanned, using gap locks or\n next-key (gap plus index-record) locks to block insertions by other\n sessions into the gaps covered by the range. This is necessary\n because "phantom rows" must be blocked for MySQL replication and\n recovery to work.\n\n *Note*: In MySQL 5.1, if the READ COMMITTED isolation level is used\n or the innodb_locks_unsafe_for_binlog system variable is enabled,\n there is no InnoDB gap locking except for foreign-key constraint\n checking and duplicate-key checking. Also, record locks for\n non-matching rows are released after MySQL has evaluated the WHERE\n condition. As of MySQL 5.1, if you use READ COMMITTED or enable\n innodb_locks_unsafe_for_binlog, you must use row-based binary\n logging.\n\no REPEATABLE READ\n\n This is the default isolation level for InnoDB. For consistent reads,\n there is an important difference from the READ COMMITTED isolation\n level: All consistent reads within the same transaction read the\n snapshot established by the first read. This convention means that if\n you issue several plain (non-locking) SELECT statements within the\n same transaction, these SELECT statements are consistent also with\n respect to each other. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n UPDATE, and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition, or a\n range-type search condition. For a unique index with a unique search\n condition, InnoDB locks only the index record found, not the gap\n before it. For other search conditions, InnoDB locks the index range\n scanned, using gap locks or next-key (gap plus index-record) locks to\n block insertions by other sessions into the gaps covered by the\n range.\n\no SERIALIZABLE\n\n This level is like REPEATABLE READ, but InnoDB implicitly converts\n all plain SELECT statements to SELECT ... LOCK IN SHARE MODE if\n autocommit is disabled. If autocommit is enabled, the SELECT is its\n own transaction. It therefore is known to be read only and can be\n serialized if performed as a consistent (non-locking) read and need\n not block for other transactions. (This means that to force a plain\n SELECT to block if other transactions have modified the selected\n rows, you should disable autocommit.)\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (445,4,'CEILING','Syntax:\nCEILING(X)\n\nReturns the smallest integer value not less than X.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT CEILING(1.23);\n -> 2\nmysql> SELECT CEILING(-1.23);\n -> -1\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (446,4,'SIN','Syntax:\nSIN(X)\n\nReturns the sine of X, where X is given in radians.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT SIN(PI());\n -> 1.2246063538224e-16\nmysql> SELECT ROUND(SIN(PI()));\n -> 0\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (447,30,'DAYOFWEEK','Syntax:\nDAYOFWEEK(date)\n\nReturns the weekday index for date (1 = Sunday, 2 = Monday, ..., 7 =\nSaturday).

To create the view explicitly in a given database,\nspecify the name as db_name.view_name when you create it.\n\nmysql> CREATE VIEW test.v AS SELECT * FROM t;\n\nBase tables and views share the same namespace within a database, so a\ndatabase cannot contain a base table and a view that have the same\nname.\n\nViews must have unique column names with no duplicates, just like base\ntables. By default, the names of the columns retrieved by the SELECT\nstatement are used for the view column names. To define explicit names\nfor the view columns, the optional column_list clause can be given as a\nlist of comma-separated identifiers. The number of names in column_list\nmust be the same as the number of columns retrieved by the SELECT\nstatement.\n\n*Note*: Prior to MySQL 5.1.29, When you modify an existing view, the\ncurrent view definition is backed up and saved. It is stored in that\ntable\'s database directory, in a subdirectory named arc. The backup\nfile for a view v is named v.frm-00001. If you alter the view again,\nthe next backup is named v.frm-00002. The three latest view backup\ndefinitions are stored. Backed up view definitions are not preserved by\nmysqldump, or any other such programs, but you can retain them using a\nfile copy operation. However, they are not needed for anything but to\nprovide you with a backup of your previous view definition. It is safe\nto remove these backup definitions, but only while mysqld is not\nrunning. If you delete the arc subdirectory or its files while mysqld\nis running, you will receive an error the next time you try to alter\nthe view: mysql> ALTER VIEW v AS SELECT * FROM t; ERROR 6 (HY000):\nError on delete of \'.\\test\\arc/v.frm-0004\' (Errcode: 2)\n\nColumns retrieved by the SELECT statement can be simple references to\ntable columns. They can also be expressions that use functions,\nconstant values, operators, and so forth.\n\nUnqualified table or view names in the SELECT statement are interpreted\nwith respect to the default database. A view can refer to tables or\nviews in other databases by qualifying the table or view name with the\nproper database name.\n\nA view can be created from many kinds of SELECT statements. It can\nrefer to base tables or other views. It can use joins, UNION, and\nsubqueries. The SELECT need not even refer to any tables. The following\nexample defines a view that selects two columns from another table, as\nwell as an expression calculated from those columns:\n\nmysql> CREATE TABLE t (qty INT, price INT);\nmysql> INSERT INTO t VALUES(3, 50);\nmysql> CREATE VIEW v AS SELECT qty, price, qty*price AS value FROM t;\nmysql> SELECT * FROM v;\n+------+-------+-------+\n| qty | price | value |\n+------+-------+-------+\n| 3 | 50 | 150 |\n+------+-------+-------+\n\nA view definition is subject to the following restrictions:\n\no The SELECT statement cannot contain a subquery in the FROM clause.\n\no The SELECT statement cannot refer to system or user variables.\n\no Within a stored program, the definition cannot refer to program\n parameters or local variables.\n\no The SELECT statement cannot refer to prepared statement parameters.\n\no Any table or view referred to in the definition must exist. However,\n after a view has been created, it is possible to drop a table or view\n that the definition refers to. In this case, use of the view results\n in an error. To check a view definition for problems of this kind,\n use the CHECK TABLE statement.\n\no The definition cannot refer to a TEMPORARY table, and you cannot\n create a TEMPORARY view.\n\no Any tables named in the view definition must exist at definition\n time.\n\no You cannot associate a trigger with a view.\n\nORDER BY is allowed in a view definition, but it is ignored if you\nselect from a view using a statement that has its own ORDER BY.\n\nFor other options or clauses in the definition, they are added to the\noptions or clauses of the statement that references the view, but the\neffect is undefined. For example, if a view definition includes a LIMIT\nclause, and you select from the view using a statement that has its own\nLIMIT clause, it is undefined which limit applies. This same principle\napplies to options such as ALL, DISTINCT, or SQL_SMALL_RESULT that\nfollow the SELECT keyword, and to clauses such as INTO, FOR UPDATE,\nLOCK IN SHARE MODE, and PROCEDURE.\n\nIf you create a view and then change the query processing environment\nby changing system variables, that may affect the results that you get\nfrom the view:\n\nmysql> CREATE VIEW v (mycol) AS SELECT \'abc\';\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> SET sql_mode = \'\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| mycol | \n+-------+\n1 row in set (0.01 sec)\n\nmysql> SET sql_mode = \'ANSI_QUOTES\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| abc | \n+-------+\n1 row in set (0.00 sec)\n\nThe DEFINER and SQL SECURITY clauses determine which MySQL account to\nuse when checking access privileges for the view when a statement is\nexecuted that references the view. They were addded in MySQL 5.1.2. The\nlegal SQL SECURITY characteristic values are DEFINER and INVOKER. These\nindicate that the required privileges must be held by the user who\ndefined or invoked the view, respectively. The default SQL SECURITY\nvalue is DEFINER.\n\nIf a user value is given for the DEFINER clause, it should be a MySQL\naccount in \'user_name\'@\'host_name\' format (the same format used in the\nGRANT statement). The user_name and host_name values both are required.\nThe definer can also be given as CURRENT_USER or CURRENT_USER(). The\ndefault DEFINER value is the user who executes the CREATE VIEW\nstatement. This is the same as specifying DEFINER = CURRENT_USER\nexplicitly.\n\nIf you specify the DEFINER clause, these rules determine the legal\nDEFINER user values:\n\no If you do not have the SUPER privilege, the only legal user value is\n your own account, either specified literally or by using\n CURRENT_USER. You cannot set the definer to some other account.\n\no If you have the SUPER privilege, you can specify any syntactically\n legal account name. If the account does not actually exist, a warning\n is generated.\n\no If the SQL SECURITY value is DEFINER but the definer account does not\n exist when the view is referenced, an error occurs.\n\nWithin a view definition, CURRENT_USER returns the view\'s DEFINER value\nby default as of MySQL 5.1.12. For older versions, and for views\ndefined with the SQL SECURITY INVOKER characteristic, CURRENT_USER\nreturns the account for the view\'s invoker. For information about user\nauditing within views, see\nhttp://dev.mysql.com/doc/refman/5.1/en/account-activity-auditing.html.… a stored routine that is defined with the SQL SECURITY DEFINER\ncharacteristic, CURRENT_USER returns the routine\'s DEFINER value. This\nalso affects a view defined within such a program, if the view\ndefinition contains a DEFINER value of CURRENT_USER.\n\nAs of MySQL 5.1.2 (when the DEFINER and SQL SECURITY clauses were\nimplemented), view privileges are checked like this:\n\no At view definition time, the view creator must have the privileges\n needed to use the top-level objects accessed by the view. For\n example, if the view definition refers to table columns, the creator\n must have privileges for the columns, as described previously. If the\n definition refers to a stored function, only the privileges needed to\n invoke the function can be checked. The privileges required when the\n function runs can be checked only as it executes: For different\n invocations of the function, different execution paths within the\n function might be taken.\n\no When a view is referenced, privileges for objects accessed by the\n view are checked against the privileges held by the view creator or\n invoker, depending on whether the SQL SECURITY characteristic is\n DEFINER or INVOKER, respectively.\n\no If reference to a view causes execution of a stored function,\n privilege checking for statements executed within the function depend\n on whether the function is defined with a SQL SECURITY characteristic\n of DEFINER or INVOKER. If the security characteristic is DEFINER, the\n function runs with the privileges of its creator. If the\n characteristic is INVOKER, the function runs with the privileges\n determined by the view\'s SQL SECURITY characteristic.\n\nPrior to MySQL 5.1.2 (before the DEFINER and SQL SECURITY clauses were\nimplemented), privileges required for objects used in a view are\nchecked at view creation time.\n\nExample: A view might depend on a stored function, and that function\nmight invoke other stored routines. For example, the following view\ninvokes a stored function f():\n\nCREATE VIEW v AS SELECT * FROM t WHERE t.id = f(t.name);\n\nSuppose that f() contains a statement such as this:\n\nIF name IS NULL then\n CALL p1();\nELSE\n CALL p2();\nEND IF;\n\nThe privileges required for executing statements within f() need to be\nchecked when f() executes. This might mean that privileges are needed\nfor p1() or p2(), depending on the execution path within f(). Those\nprivileges must be checked at runtime, and the user who must possess\nthe privileges is determined by the SQL SECURITY values of the view v\nand the function f().\n\nThe DEFINER and SQL SECURITY clauses for views are extensions to\nstandard SQL. In standard SQL, views are handled using the rules for\nSQL SECURITY INVOKER.\n\nIf you invoke a view that was created before MySQL 5.1.2, it is treated\nas though it was created with a SQL SECURITY DEFINER clause and with a\nDEFINER value that is the same as your account. However, because the\nactual definer is unknown, MySQL issues a warning. To make the warning\ngo away, it is sufficient to re-create the view so that the view\ndefinition includes a DEFINER clause.\n\nThe optional ALGORITHM clause is a MySQL extension to standard SQL. It\naffects how MySQL processes the view. ALGORITHM takes three values:\nMERGE, TEMPTABLE, or UNDEFINED. The default algorithm is UNDEFINED if\nno ALGORITHM clause is present. For more information, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-algorithms.html.\n\nSome views are updatable. That is, you can use them in statements such\nas UPDATE, DELETE, or INSERT to update the contents of the underlying\ntable. For a view to be updatable, there must be a one-to-one\nrelationship between the rows in the view and the rows in the\nunderlying table. There are also certain other constructs that make a\nview non-updatable.\n\nThe WITH CHECK OPTION clause can be given for an updatable view to\nprevent inserts or updates to rows except those for which the WHERE\nclause in the select_statement is true.\n\nIn a WITH CHECK OPTION clause for an updatable view, the LOCAL and\nCASCADED keywords determine the scope of check testing when the view is\ndefined in terms of another view. The LOCAL keyword restricts the CHECK\nOPTION only to the view being defined. CASCADED causes the checks for\nunderlying views to be evaluated as well. When neither keyword is\ngiven, the default is CASCADED.\n\nFor more information about updatable views and the WITH CHECK OPTION\nclause, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-updatability.html.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-view.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-view.html'); -insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (452,35,'TRIM','Syntax:\nTRIM([{BOTH | LEADING | TRAILING} [remstr] FROM] str), TRIM([remstr\nFROM] str)\n\nReturns the string str with all remstr prefixes or suffixes removed.

This is a common situation\nwhen you use MySQL for logging and you also periodically run SELECT and\nUPDATE statements that take a long time to complete.\n\nWhen a client uses INSERT DELAYED, it gets an okay from the server at\nonce, and the row is queued to be inserted when the table is not in use\nby any other thread.\n\nAnother major benefit of using INSERT DELAYED is that inserts from many\nclients are bundled together and written in one block. This is much\nfaster than performing many separate inserts.\n\nNote that INSERT DELAYED is slower than a normal INSERT if the table is\nnot otherwise in use. There is also the additional overhead for the\nserver to handle a separate thread for each table for which there are\ndelayed rows. This means that you should use INSERT DELAYED only when\nyou are really sure that you need it.\n\nThe queued rows are held only in memory until they are inserted into\nthe table.

This is used by ANALYSE() to check\n whether the optimal data type should be of type ENUM; if there are\n more than max_elements distinct values, then ENUM is not a suggested\n type.\n\no max_memory (default 8192) is the maximum amount of memory that\n ANALYSE() should allocate per column while trying to find all\n distinct values.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/procedure-analyse.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/procedure-analyse.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (184,25,'CHANGE MASTER TO','Syntax:\nCHANGE MASTER TO master_def [, master_def] ...\n\nmaster_def:\n MASTER_BIND = \'interface_name\'\n | MASTER_HOST = \'host_name\'\n | MASTER_USER = \'user_name\'\n | MASTER_PASSWORD = \'password\'\n | MASTER_PORT = port_num\n | MASTER_CONNECT_RETRY = interval\n | MASTER_HEARTBEAT_PERIOD = interval\n | MASTER_LOG_FILE = \'master_log_name\'\n | MASTER_LOG_POS = master_log_pos\n | RELAY_LOG_FILE = \'relay_log_name\'\n | RELAY_LOG_POS = relay_log_pos\n | MASTER_SSL = {0|1}\n | MASTER_SSL_CA = \'ca_file_name\'\n | MASTER_SSL_CAPATH = \'ca_directory_name\'\n | MASTER_SSL_CERT = \'cert_file_name\'\n | MASTER_SSL_KEY = \'key_file_name\'\n | MASTER_SSL_CIPHER = \'cipher_list\'\n | MASTER_SSL_VERIFY_SERVER_CERT = {0|1}\n\nCHANGE MASTER TO changes the parameters that the slave server uses for\nconnecting to and communicating with the master server. It also updates\nthe contents of the master.info and relay-log.info files.\n\nMASTER_USER, MASTER_PASSWORD, MASTER_SSL, MASTER_SSL_CA,\nMASTER_SSL_CAPATH, MASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER,\nand MASTER_SSL_VERIFY_SERVER_CERT provide information to the slave\nabout how to connect to its master. MASTER_SSL_VERIFY_SERVER_CERT was\nadded in MySQL 5.1.18. It is used as described for the\n--ssl-verify-server-cert option in\nhttp://dev.mysql.com/doc/refman/5.1/en/ssl-options.html.\n\nMASTER_CONN… specifies how many seconds to wait between connect\nretries. The default is 60. The number of reconnection attempts is\nlimited by the --master-retry-count server option; for more\ninformation, see\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-options.html.\n\nThe SSL options (MASTER_SSL, MASTER_SSL_CA, MASTER_SSL_CAPATH,\nMASTER_SSL_CERT, MASTER_SSL_KEY, MASTER_SSL_CIPHER), and\nMASTER_SSL_VERIFY_SERVER_CERT can be changed even on slaves that are\ncompiled without SSL support. They are saved to the master.info file,\nbut are ignored unless you use a server that has SSL support enabled.\n\nIf you don\'t specify a given parameter, it keeps its old value, except\nas indicated in the following discussion. For example, if the password\nto connect to your MySQL master has changed, you just need to issue\nthese statements to tell the slave about the new password:\n\nSTOP SLAVE; -- if replication was running\nCHANGE MASTER TO MASTER_PASSWORD=\'new3cret\';\nSTART SLAVE; -- if you want to restart replication\n\nThere is no need to specify the parameters that do not change (host,\nport, user, and so forth).\n\nMASTER_HOST and MASTER_PORT are the host name (or IP address) of the\nmaster host and its TCP/IP port.\n\nThe next two options are available only in MySQL Cluster NDB 6.3 and\n6.4; they are not supported in mainline MySQL 5.1:\n\no MASTER_BIND is for use on replication slaves having multiple network\n interfaces, and determines which of the slave\'s network interfaces is\n chosen for connecting to the master. It is also possible to determine\n which network interface is to be used in such cases by starting the\n slave mysqld process with the --master-bind option.\n\n The ability to bind a replication slave to specific network interface\n was added in MySQL Cluster NDB 6.3.4.\n\no MASTER_HEARTBEAT_PERIOD is used to set the interval in seconds\n between replication heartbeats. Whenever the master\'s binlog is\n updated with an event, the waiting period for the next heartbeat is\n reset. interval is a decimal value having the range 0 to 4294967\n seconds and a resolution to hundredths of a second; the smallest\n nonzero value is 0.001. Heartbeats are sent by the master only if\n there are no unsent events in the binlog file for a period longer\n than interval.\n\n Setting interval to 0 disables heartbeats altogether. The default\n value for interval is equal to the value of slave_net_timeout divided\n by 2.\n\n *Note*: Setting @@global.slave_net_timeout to a value less than that\n of the current heartbeat interval results in a warning being issued.\n\n Issuing RESET SLAVE resets the heartbeat interval to the default.\n\n MASTER_HEARTBEAT_PERIOD was added in MySQL Cluster NDB 6.3.4.\n\n*Note*: Replication cannot use Unix socket files. You must be able to\nconnect to the master MySQL server using TCP/IP.\n\nIf you specify MASTER_HOST or MASTER_PORT, the slave assumes that the\nmaster server is different from before (even if you specify a host or\nport value that is the same as the current value.) In this case, the\nold values for the master binary log name and position are considered\nno longer applicable, so if you do not specify MASTER_LOG_FILE and\nMASTER_LOG_POS in the statement, MASTER_LOG_FILE=\'\' and\nMASTER_LOG_POS=4 are silently appended to it.\n\nSetting MASTER_HOST=\'\' --- that is, setting its value explicitly to an\nempty string --- is not the same as not setting it at all. Setting this\noption to an empty string causes START SLAVE subsequently to fail. This\nissue is addressed in MySQL 6.0. (Bug#28796\n(http://bugs.mysql.com/28796))\n\nMASTER_LOG_FILE and MASTER_LOG_POS are the coordinates at which the\nslave I/O thread should begin reading from the master the next time the\nthread starts. If you specify either of them, you cannot specify\nRELAY_LOG_FILE or RELAY_LOG_POS. If neither of MASTER_LOG_FILE or\nMASTER_LOG_POS are specified, the slave uses the last coordinates of\nthe slave SQL thread before CHANGE MASTER TO was issued. This ensures\nthat there is no discontinuity in replication, even if the slave SQL\nthread was late compared to the slave I/O thread, when you merely want\nto change, say, the password to use.\n\nCHANGE MASTER TO deletes all relay log files and starts a new one,\nunless you specify RELAY_LOG_FILE or RELAY_LOG_POS. In that case, relay\nlogs are kept; the relay_log_purge global variable is set silently to\n0.\n\nCHANGE MASTER TO is useful for setting up a slave when you have the\nsnapshot of the master and have recorded the log and the offset\ncorresponding to it. After loading the snapshot into the slave, you can\nrun CHANGE MASTER TO MASTER_LOG_FILE=\'log_name_on_master\',\nMASTER_LOG_POS=log_offset_on_master on the slave.\n\nThe following example changes the master and master\'s binary log\ncoordinates. This is used when you want to set up the slave to\nreplicate the master:\n\nCHANGE MASTER TO\n MASTER_HOST=\'master2.mycompany.com\',\n MASTER_USER=\'replication\',\n MASTER_PASSWORD=\'bigs3cret\',\n MASTER_PORT=3306,\n MASTER_LOG_FILE=\'master2-bin.001\',\n MASTER_LOG_POS=4,\n MASTER_CONNECT_RETRY=10;\n\nThe next example shows an operation that is less frequently employed.\nIt is used when the slave has relay logs that you want it to execute\nagain for some reason. To do this, the master need not be reachable.\nYou need only use CHANGE MASTER TO and start the SQL thread (START\nSLAVE SQL_THREAD):\n\nCHANGE MASTER TO\n RELAY_LOG_FILE=\'slave-relay-bin.006\',\n RELAY_LOG_POS=4025;\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/change-master-to.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (185,37,'DROP DATABASE','Syntax:\nDROP {DATABASE | SCHEMA} [IF EXISTS] db_name\n\nDROP DATABASE drops all tables in the database and deletes the\ndatabase.

One data file is\ncreated and added to the tablespace using this statement. Additional\ndata files may be added to the tablespace by using the ALTER TABLESPACE\nstatement (see [HELP ALTER TABLESPACE]). For rules covering the naming\nof tablespaces, see\nhttp://dev.mysql.com/doc/refman/5.1/en/identifiers.html.\n\n*Note*: All MySQL Cluster Disk Data objects share the same namespace.\nThis means that each Disk Data object must be uniquely named (and not\nmerely each Disk Data object of a given type). For example, you cannot\nhave a tablespace and a log file group with the same name, or a\ntablespace and a data file with the same name.\n\nPrior to MySQL Cluster NDB 6.2.17, 6.3.23, and 6.4.3, path and file\nnames for data files could not be longer than 128 characters.\n(Bug#31770 (http://bugs.mysql.com/31770))\n\nA log file group of one or more UNDO log files must be assigned to the\ntablespace to be created with the USE LOGFILE GROUP clause.\nlogfile_group must be an existing log file group created with CREATE\nLOGFILE GROUP (see\nhttp://dev.mysql.com/doc/refman/5.1/en/create-logfile-group.html).\nMu… tablespaces may use the same log file group for UNDO logging.\n\nThe EXTENT_SIZE sets the size, in bytes, of the extents used by any\nfiles belonging to the tablespace. The default value is 1M. The minimum\nsize is 32K, and theoretical maximum is 2G, although the practical\nmaximum size depends on a number of factors. In most cases, changing\nthe extent size does not have any measurable effect on performance, and\nthe default value is recommended for all but the most unusual\nsituations.\n\nAn extent is a unit of disk space allocation. One extent is filled with\nas much data as that extent can contain before another extent is used.\nIn theory, up to 65,535 (64K) extents may used per data file; however,\nthe recommended maximum is 32,768 (32K). The recommended maximum size\nfor a single data file is 32G --- that is, 32K extents x 1 MB per\nextent. In addition, once an extent is allocated to a given partition,\nit cannot be used to store data from a different partition; an extent\ncannot store data from more than one partition. This means, for example\nthat a tablespace having a single datafile whose INITIAL_SIZE is 256 MB\nand whose EXTENT_SIZE is 128M has just two extents, and so can be used\nto store data from at most two different disk data table partitions.\n\nYou can see how many extents remain free in a given data file by\nquerying the INFORMATION_SCHEMA.FILES table, and so derive an estimate\nfor how much space remains free in the file. For further discussion and\nexamples, see http://dev.mysql.com/doc/refman/5.1/en/files-table.html.\n\nThe INITIAL_SIZE parameter sets the data file\'s total size in bytes.\nOnce the file has been created, its size cannot be changed; however,\nyou can add more data files to the tablespace using ALTER TABLESPACE\n... ADD DATAFILE. See [HELP ALTER TABLESPACE].\n\nINITIAL_SIZE is optional; its default value is 128M.\n\nOn 32-bit systems, the maximum supported value for INITIAL_SIZE is 4G.\n(Bug#29186 (http://bugs.mysql.com/29186))\n\nWhen setting EXTENT_SIZE or INITIAL_SIZE (either or both), you may\noptionally follow the number with a one-letter abbreviation for an\norder of magnitude, similar to those used in my.cnf. Generally, this is\none of the letters M (for megabytes) or G (for gigabytes).\n\nAUTOEXTEND_SIZE, MAX_SIZE, NODEGROUP, WAIT, and COMMENT are parsed but\nignored, and so have no effect in MySQL 5.1. These options are intended\nfor future expansion.\n\nThe ENGINE parameter determines the storage engine which uses this\ntablespace, with engine_name being the name of the storage engine. In\nMySQL 5.1, engine_name must be one of the values NDB or NDBCLUSTER.\n\nWhen CREATE TABLESPACE is used with ENGINE = NDB, a tablespace and\nassociated data file are created on each Cluster data node. You can\nverify that the data files were created and obtain information about\nthem by querying the INFORMATION_SCHEMA.FILES table. For example:\n\nmysql> SELECT LOGFILE_GROUP_NAME, FILE_NAME, EXTRA\n -> FROM INFORMATION_SCHEMA.FILES\n -> WHERE TABLESPACE_NAME = \'newts\' AND FILE_TYPE = \'DATAFILE\';\n+--------------------+-------------+----------------+\n| LOGFILE_GROUP_NAME | FILE_NAME | EXTRA |\n+--------------------+-------------+----------------+\n| lg_3 | newdata.dat | CLUSTER_NODE=3 |\n| lg_3 | newdata.dat | CLUSTER_NODE=4 |\n+--------------------+-------------+----------------+\n2 rows in set (0.01 sec)\n\n(See http://dev.mysql.com/doc/refman/5.1/en/files-table.html.)\n\nCREATE TABLESPACE was added in MySQL 5.1.6.

By default, a routine is\nassociated with the default database. To associate the routine\nexplicitly with a given database, specify the name as db_name.sp_name\nwhen you create it.\n\nThe CREATE FUNCTION statement is also used in MySQL to support UDFs\n(user-defined functions). See\nhttp://dev.mysql.com/doc/refman/5.1/en/adding-functions.html. A UDF can\nbe regarded as an external stored function. However, do note that\nstored functions share their namespace with UDFs. See\nhttp://dev.mysql.com/doc/refman/5.1/en/function-resolution.html, for\nthe rules describing how the server interprets references to different\nkinds of functions.\n\nTo invoke a stored procedure, use the CALL statement (see [HELP CALL]).\nTo invoke a stored function, refer to it in an expression. The function\nreturns a value during expression evaluation.\n\nTo execute the CREATE PROCEDURE or CREATE FUNCTION statement, it is\nnecessary to have the CREATE ROUTINE privilege. By default, MySQL\nautomatically grants the ALTER ROUTINE and EXECUTE privileges to the\nroutine creator. This behavior can be changed by disabling the\nautomatic_sp_privileges system variable. See\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-routines-privileges.html… binary logging is enabled, the CREATE FUNCTION statement might also\nrequire the SUPER privilege, as described in\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-logging.html.\n\… DEFINER and SQL SECURITY clauses specify the security context to be\nused when checking access privileges at routine execution time, as\ndescribed later.\n\nIf the routine name is the same as the name of a built-in SQL function,\na syntax error occurs unless you use a space between the name and the\nfollowing parenthesis when defining the routine or invoking it later.\nFor this reason, avoid using the names of existing SQL functions for\nyour own stored routines.\n\nThe IGNORE_SPACE SQL mode applies to built-in functions, not to stored\nroutines. It is always allowable to have spaces after a stored routine\nname, regardless of whether IGNORE_SPACE is enabled.\n\nThe parameter list enclosed within parentheses must always be present.\nIf there are no parameters, an empty parameter list of () should be\nused. Parameter names are not case sensitive.\n\nEach parameter is an IN parameter by default. To specify otherwise for\na parameter, use the keyword OUT or INOUT before the parameter name.\n\n*Note*: Specifying a parameter as IN, OUT, or INOUT is valid only for a\nPROCEDURE. (FUNCTION parameters are always regarded as IN parameters.)\n\nAn IN parameter passes a value into a procedure. The procedure might\nmodify the value, but the modification is not visible to the caller\nwhen the procedure returns. An OUT parameter passes a value from the\nprocedure back to the caller. Its initial value is NULL within the\nprocedure, and its value is visible to the caller when the procedure\nreturns. An INOUT parameter is initialized by the caller, can be\nmodified by the procedure, and any change made by the procedure is\nvisible to the caller when the procedure returns.\n\nFor each OUT or INOUT parameter, pass a user-defined variable in the\nCALL statement that invokes the procedure so that you can obtain its\nvalue when the procedure returns. If you are calling the procedure from\nwithin another stored procedure or function, you can also pass a\nroutine parameter or local routine variable as an IN or INOUT\nparameter.\n\nThe following example shows a simple stored procedure that uses an OUT\nparameter:\n\nmysql> delimiter //\n\nmysql> CREATE PROCEDURE simpleproc (OUT param1 INT)\n -> BEGIN\n -> SELECT COUNT(*) INTO param1 FROM t;\n -> END//\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> delimiter ;\n\nmysql> CALL simpleproc(@a);\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT @a;\n+------+\n| @a |\n+------+\n| 3 |\n+------+\n1 row in set (0.00 sec)\n\nThe example uses the mysql client delimiter command to change the\nstatement delimiter from ; to // while the procedure is being defined.\nThis allows the ; delimiter used in the procedure body to be passed\nthrough to the server rather than being interpreted by mysql itself.\nSee\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-programs-defini… RETURNS clause may be specified only for a FUNCTION, for which it\nis mandatory. It indicates the return type of the function, and the\nfunction body must contain a RETURN value statement. If the RETURN\nstatement returns a value of a different type, the value is coerced to\nthe proper type. For example, if a function specifies an ENUM or SET\nvalue in the RETURNS clause, but the RETURN statement returns an\ninteger, the value returned from the function is the string for the\ncorresponding ENUM member of set of SET members.\n\nThe following example function takes a parameter, performs an operation\nusing an SQL function, and returns the result. In this case, it is\nunnecessary to use delimiter because the function definition contains\nno internal ; statement delimiters:\n\nmysql> CREATE FUNCTION hello (s CHAR(20))\nmysql> RETURNS CHAR(50) DETERMINISTIC\n -> RETURN CONCAT(\'Hello, \',s,\'!\');\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT hello(\'world\');\n+----------------+\n| hello(\'world\') |\n+----------------+\n| Hello, world! |\n+----------------+\n1 row in set (0.00 sec)\n\nParameter types and function return types can be declared to use any\nvalid data type, except that the COLLATE attribute cannot be used.\n\nThe routine_body consists of a valid SQL procedure statement. This can\nbe a simple statement such as SELECT or INSERT, or it can be a compound\nstatement written using BEGIN and END. Compound statements can contain\ndeclarations, loops, and other control structure statements. The syntax\nfor these statements is described in\nhttp://dev.mysql.com/doc/refman/5.1/en/sql-syntax-compound-statements.h… allows routines to contain DDL statements, such as CREATE and\nDROP. MySQL also allows stored procedures (but not stored functions) to\ncontain SQL transaction statements such as COMMIT. Stored functions may\nnot contain statements that perform explicit or implicit commit or\nrollback. Support for these statements is not required by the SQL\nstandard, which states that each DBMS vendor may decide whether to\nallow them.\n\nStatements that return a result set can be used within a stored\nprocedcure but not within a stored function. This prohibition includes\nSELECT statements that do not have an INTO var_list clause and other\nstatements such as SHOW, EXPLAIN, and CHECK TABLE. For statements that\ncan be determined at function definition time to return a result set, a\nNot allowed to return a result set from a function error occurs\n(ER_SP_NO_RETSET). For statements that can be determined only at\nruntime to return a result set, a PROCEDURE %s can\'t return a result\nset in the given context error occurs (ER_SP_BADSELECT).\n\nUSE statements within stored routines are disallowed. When a routine is\ninvoked, an implicit USE db_name is performed (and undone when the\nroutine terminates). The causes the routine to have the given default\ndatabase while it executes. References to objects in databases other\nthan the routine default database should be qualified with the\nappropriate database name.\n\nFor additional information about statements that are not allowed in\nstored routines, see\nhttp://dev.mysql.com/doc/refman/5.1/en/stored-program-restrictions.htm… information about invoking stored procedures from within programs\nwritten in a language that has a MySQL interface, see [HELP CALL].\n\nMySQL stores the sql_mode system variable setting that is in effect at\nthe time a routine is created, and always executes the routine with\nthis setting in force, regardless of the server SQL mode in effect when\nthe routine is invoked.\n\nThe switch from the SQL mode of the invoker to that of the routine\noccurs after evaluation of arguments and assignment of the resulting\nvalues to routine parameters. If you define a routine in strict SQL\nmode but invoke it in nonstrict mode, assignment of arguments to\nroutine parameters does not take place in strict mode. If you require\nthat expressions passed to a routine be assigned in strict SQL mode,\nyou should invoke the routine with strict mode in effect.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-procedure.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (300,20,'VARBINARY','VARBINARY(M)\n\nThe VARBINARY type is similar to the VARCHAR type, but stores binary\nbyte strings rather than nonbinary character strings.

(Bug#36763\n(http://bugs.mysql.com/36763)) However, it is still applied on\nreplication slaves using InnoDB in the manner described previously.\n\nThe count of rows affected by TRUNCATE TABLE is accurate only when it\nis mapped to a DELETE statement.\n\nFor other storage engines, TRUNCATE TABLE differs from DELETE in the\nfollowing ways in MySQL 5.1:\n\no Truncate operations drop and re-create the table, which is much\n faster than deleting rows one by one, particularly for large tables.\n\no Truncate operations cause an implicit commit.\n\no Truncation operations cannot be performed if the session holds an\n active table lock.\n\no Truncation operations do not return a meaningful value for the number\n of deleted rows. The usual result is "0 rows affected," which should\n be interpreted as "no information."\n\no As long as the table format file tbl_name.frm is valid, the table can\n be re-created as an empty table with TRUNCATE TABLE, even if the data\n or index files have become corrupted.\n\no The table handler does not remember the last used AUTO_INCREMENT\n value, but starts counting from the beginning. This is true even for\n MyISAM and InnoDB, which normally do not reuse sequence values.\n\no When used with partitioned tables, TRUNCATE TABLE preserves the\n partitioning; that is, the data and index files are dropped and\n re-created, while the partition definitions (.par) file is\n unaffected.\n\no Since truncation of a table does not make any use of DELETE, the\n TRUNCATE statement does not invoke ON DELETE triggers.\n\nTRUNCATE TABLE requires the DROP privilege as of MySQL 5.1.16.

The latter requires Perl and two Perl\nmodules (DBI and DBD:mysql) and works for MyISAM and ARCHIVE tables\nonly. With mysqldump, you can create SQL dumps on the master and pipe\n(or copy) these to a mysql client on the slave.

(spin_rounds\n divided by spin_waits provides the average round count.)\n\n o os_waits indicates the number of operating system waits. This\n occurs when the spinlock did not work (the mutex was not locked\n during the spinlock and it was necessary to yield to the operating\n system and wait).\n\n o os_yields indicates the number of times a the thread trying to lock\n a mutex gave up its timeslice and yielded to the operating system\n (on the presumption that allowing other threads to run will free\n the mutex so that it can be locked).\n\n o os_wait_times indicates the amount of time (in ms) spent in\n operating system waits, if the timed_mutexes system variable is 1\n (ON).

The line number may change\n depending on your version of MySQL.\n\no Status\n\n This field displays the same values as previously described (count,\n spin_waits, spin_rounds, os_waits, os_yields, os_wait_times), but\n only if UNIV_DEBUG was defined at MySQL compilation time (for\n example, in include/univ.h in the InnoDB part of the MySQL source\n tree). If UNIV_DEBUG was not defined, the statement displays only the\n os_waits value. In the latter case (without UNIV_DEBUG), the\n information on which the output is based is insufficient to\n distinguish regular mutexes and mutexes that protect rw-locks (which\n allow multiple readers or a single writer).

Plugin names are\nnot case sensitive. For maximal compatibility, plugin names should be\nlimited to ASCII letters, digits, and underscore, because they are used\nin C source files, shell command lines, M4 and Bourne shell scripts,\nand SQL environments.\n\nplugin_library is the name of the shared library that contains the\nplugin code. The name includes the file name extension (for example,\nlibmyplugin.so or libmyplugin.dylib).\n\nThe shared library must be located in the plugin directory (that is,\nthe directory named by the plugin_dir system variable). The library\nmust be in the plugin directory itself, not in a subdirectory. By\ndefault, plugin_dir is plugin directory under the directory named by\nthe pkglibdir configuration variable, but it can be changed by setting\nthe value of plugin_dir at server startup. For example, set its value\nin a my.cnf file:\n\n[mysqld]\nplugin_dir=/path/to/plugin/directory\n\nIf the value of plugin_dir is a relative path name, it is taken to be\nrelative to the MySQL base directory (the value of the basedir system\nvariable).\n\nINSTALL PLUGIN adds a line to the mysql.plugin table that describes the\nplugin. This table contains the plugin name and library file name.\n\nAs of MySQL 5.1.33, INSTALL PLUGIN causes the server to read option\n(my.cnf) files just as during server startup. This enables the plugin\nto pick up any relevant options from those files. It is possible to add\nplugin options to an option file even before loading a plugin (if the\nloose prefix is used). It is also possible to uninstall a plugin, edit\nmy.cnf, and install the plugin again. Restarting the plugin this way\nenables it to the new option values without a server restart.\n\nBefore MySQL 5.1.33, a plugin is started with each option set to its\ndefault value.\n\nINSTALL PLUGIN also loads and initializes the plugin code to make the\nplugin available for use. A plugin is initialized by executing its\ninitialization function, which handles any setup that the plugin must\nperform before it can be used.\n\nTo use INSTALL PLUGIN, you must have the INSERT privilege for the\nmysql.plugin table.\n\nAt server startup, the server loads and initializes any plugin that is\nlisted in the mysql.plugin table. This means that a plugin is installed\nwith INSTALL PLUGIN only once, not every time the server starts. Plugin\nloading at startup does not occur if the server is started with the\n--skip-grant-tables option.\n\nWhen the server shuts down, it executes the deinitialization function\nfor each plugin that is loaded so that the plugin has a change to\nperform any final cleanup.\n\nFor options that control individual plugin loading at server startup,\nsee http://dev.mysql.com/doc/refman/5.1/en/server-plugin-options.html.\nIf you need to load plugins for a single server startup when the\n--skip-grant-tables option is given (which tells the server not to read\nsystem tables), use the --plugin-load option.

The file name must be given as a literal string.\n\nLOAD DATA INFILE is the complement of SELECT ... INTO OUTFILE. (See\nhttp://dev.mysql.com/doc/refman/5.1/en/select.html.) To write data from\na table to a file, use SELECT ... INTO OUTFILE. To read the file back\ninto a table, use LOAD DATA INFILE. The syntax of the FIELDS and LINES\nclauses is the same for both statements. Both clauses are optional, but\nFIELDS must precede LINES if both are specified.\n\nFor more information about the efficiency of INSERT versus LOAD DATA\nINFILE and speeding up LOAD DATA INFILE, see\nhttp://dev.mysql.com/doc/refman/5.1/en/insert-speed.html.\n\nThe character set indicated by the character_set_database system\nvariable is used to interpret the information in the file. SET NAMES\nand the setting of character_set_client do not affect interpretation of\ninput. If the contents of the input file use a character set that\ndiffers from the default, it is usually preferable to specify the\ncharacter set of the file by using the CHARACTER SET clause, which is\navailable as of MySQL 5.1.17. A character set of binary specifies "no\nconversion."\n\nLOAD DATA INFILE interprets all fields in the file as having the same\ncharacter set, regardless of the data types of the columns into which\nfield values are loaded. For proper interpretation of file contents,\nyou must ensure that it was written with the correct character set. For\nexample, if you write a data file with mysqldump -T or by issuing a\nSELECT ... INTO OUTFILE statement in mysql, be sure to use a\n--default-character-set option with mysqldump or mysql so that output\nis written in the character set to be used when the file is loaded with\nLOAD DATA INFILE.\n\nNote that it is currently not possible to load data files that use the\nucs2, utf16, or utf32 character set.\n\nAs of MySQL 5.1.6, the character_set_filesystem system variable\ncontrols the interpretation of the file name.\n\nYou can also load data files by using the mysqlimport utility; it\noperates by sending a LOAD DATA INFILE statement to the server. The\n--local option causes mysqlimport to read data files from the client\nhost. You can specify the --compress option to get better performance\nover slow networks if the client and server support the compressed\nprotocol. See http://dev.mysql.com/doc/refman/5.1/en/mysqlimport.html.\n\nIf you use LOW_PRIORITY, execution of the LOAD DATA statement is\ndelayed until no other clients are reading from the table. This affects\nonly storage engines that use only table-level locking (MyISAM, MEMORY,\nMERGE).\n\nIf you specify CONCURRENT with a MyISAM table that satisfies the\ncondition for concurrent inserts (that is, it contains no free blocks\nin the middle), other threads can retrieve data from the table while\nLOAD DATA is executing. Using this option affects the performance of\nLOAD DATA a bit, even if no other thread is using the table at the same\ntime.\n\nCONCURRENT is not replicated when using statement-based replication;\nhowever, it is replicated when using row-based replication. See\nhttp://dev.mysql.com/doc/refman/5.1/en/replication-features-load-data.…, for more information.\n\n*Note*: Prior to MySQL 5.1.23, LOAD DATA performed very poorly when\nimporting into partitioned tables. The statement now uses buffering to\nimprove performance; however, the buffer uses 130 KB memory per\npartition to achieve this. (Bug#26527 (http://bugs.mysql.com/26527))\n\nThe LOCAL keyword, if specified, is interpreted with respect to the\nclient end of the connection:\n\no If LOCAL is specified, the file is read by the client program on the\n client host and sent to the server. The file can be given as a full\n path name to specify its exact location. If given as a relative path\n name, the name is interpreted relative to the directory in which the\n client program was started.\n\no If LOCAL is not specified, the file must be located on the server\n host and is read directly by the server. The server uses the\n following rules to locate the file:\n\n o If the file name is an absolute path name, the server uses it as\n given.\n\n o If the file name is a relative path name with one or more leading\n components, the server searches for the file relative to the\n server\'s data directory.\n\n o If a file name with no leading components is given, the server\n looks for the file in the database directory of the default\n database.\n\nNote that, in the non-LOCAL case, these rules mean that a file named as\n./myfile.txt is read from the server\'s data directory, whereas the file\nnamed as myfile.txt is read from the database directory of the default\ndatabase. For example, if db1 is the default database, the following\nLOAD DATA statement reads the file data.txt from the database directory\nfor db1, even though the statement explicitly loads the file into a\ntable in the db2 database:\n\nLOAD DATA INFILE \'data.txt\' INTO TABLE db2.my_table;\n\nWindows path names are specified using forward slashes rather than\nbackslashes.

The default level is REPEATABLE\nREAD. For additional information about InnoDB record-level locks and\nhow it uses them to execute various types of statements, see\nhttp://dev.mysql.com/doc/refman/5.1/en/innodb-record-level-locks.html,… http://dev.mysql.com/doc/refman/5.1/en/innodb-locks-set.html.\n\nThe following list describes how MySQL supports the different\ntransaction levels:\n\no READ UNCOMMITTED\n\n SELECT statements are performed in a nonlocking fashion, but a\n possible earlier version of a row might be used. Thus, using this\n isolation level, such reads are not consistent. This is also called a\n "dirty read." Otherwise, this isolation level works like READ\n COMMITTED.\n\no READ COMMITTED\n\n A somewhat Oracle-like isolation level with respect to consistent\n (nonlocking) reads: Each consistent read, even within the same\n transaction, sets and reads its own fresh snapshot. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n InnoDB locks only index records, not the gaps before them, and thus\n allows the free insertion of new records next to locked records. For\n UPDATE and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition (such as\n WHERE id = 100), or a range-type search condition (such as WHERE id >\n 100). For a unique index with a unique search condition, InnoDB locks\n only the index record found, not the gap before it. For range-type\n searches, InnoDB locks the index range scanned, using gap locks or\n next-key (gap plus index-record) locks to block insertions by other\n sessions into the gaps covered by the range. This is necessary\n because "phantom rows" must be blocked for MySQL replication and\n recovery to work.\n\n *Note*: In MySQL 5.1, if the READ COMMITTED isolation level is used\n or the innodb_locks_unsafe_for_binlog system variable is enabled,\n there is no InnoDB gap locking except for foreign-key constraint\n checking and duplicate-key checking. Also, record locks for\n nonmatching rows are released after MySQL has evaluated the WHERE\n condition. As of MySQL 5.1, if you use READ COMMITTED or enable\n innodb_locks_unsafe_for_binlog, you must use row-based binary\n logging.\n\no REPEATABLE READ\n\n This is the default isolation level for InnoDB. For consistent reads,\n there is an important difference from the READ COMMITTED isolation\n level: All consistent reads within the same transaction read the\n snapshot established by the first read. This convention means that if\n you issue several plain (nonlocking) SELECT statements within the\n same transaction, these SELECT statements are consistent also with\n respect to each other. See\n http://dev.mysql.com/doc/refman/5.1/en/innodb-consistent-read.html.\n\n For locking reads (SELECT with FOR UPDATE or LOCK IN SHARE MODE),\n UPDATE, and DELETE statements, locking depends on whether the\n statement uses a unique index with a unique search condition, or a\n range-type search condition. For a unique index with a unique search\n condition, InnoDB locks only the index record found, not the gap\n before it. For other search conditions, InnoDB locks the index range\n scanned, using gap locks or next-key (gap plus index-record) locks to\n block insertions by other sessions into the gaps covered by the\n range.\n\no SERIALIZABLE\n\n This level is like REPEATABLE READ, but InnoDB implicitly converts\n all plain SELECT statements to SELECT ... LOCK IN SHARE MODE if\n autocommit is disabled. If autocommit is enabled, the SELECT is its\n own transaction. It therefore is known to be read only and can be\n serialized if performed as a consistent (nonlocking) read and need\n not block for other transactions. (This means that to force a plain\n SELECT to block if other transactions have modified the selected\n rows, you should disable autocommit.)\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (446,4,'CEILING','Syntax:\nCEILING(X)\n\nReturns the smallest integer value not less than X.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT CEILING(1.23);\n -> 2\nmysql> SELECT CEILING(-1.23);\n -> -1\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (447,4,'SIN','Syntax:\nSIN(X)\n\nReturns the sine of X, where X is given in radians.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html\n\n','mysql> SELECT SIN(PI());\n -> 1.2246063538224e-16\nmysql> SELECT ROUND(SIN(PI()));\n -> 0\n','http://dev.mysql.com/doc/refman/5.1/en/mathematical-functions.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (448,30,'DAYOFWEEK','Syntax:\nDAYOFWEEK(date)\n\nReturns the weekday index for date (1 = Sunday, 2 = Monday, ..., 7 =\nSaturday).

By default, the names of the columns retrieved by the SELECT\nstatement are used for the view column names. To define explicit names\nfor the view columns, the optional column_list clause can be given as a\nlist of comma-separated identifiers. The number of names in column_list\nmust be the same as the number of columns retrieved by the SELECT\nstatement.\n\n*Note*: Prior to MySQL 5.1.29, when you modify an existing view, the\ncurrent view definition is backed up and saved. It is stored in that\ntable\'s database directory, in a subdirectory named arc. The backup\nfile for a view v is named v.frm-00001. If you alter the view again,\nthe next backup is named v.frm-00002. The three latest view backup\ndefinitions are stored. Backed up view definitions are not preserved by\nmysqldump, or any other such programs, but you can retain them using a\nfile copy operation. However, they are not needed for anything but to\nprovide you with a backup of your previous view definition. It is safe\nto remove these backup definitions, but only while mysqld is not\nrunning. If you delete the arc subdirectory or its files while mysqld\nis running, you will receive an error the next time you try to alter\nthe view: mysql> ALTER VIEW v AS SELECT * FROM t; ERROR 6 (HY000):\nError on delete of \'.\\test\\arc/v.frm-0004\' (Errcode: 2)\n\nColumns retrieved by the SELECT statement can be simple references to\ntable columns. They can also be expressions that use functions,\nconstant values, operators, and so forth.\n\nUnqualified table or view names in the SELECT statement are interpreted\nwith respect to the default database. A view can refer to tables or\nviews in other databases by qualifying the table or view name with the\nproper database name.\n\nA view can be created from many kinds of SELECT statements. It can\nrefer to base tables or other views. It can use joins, UNION, and\nsubqueries. The SELECT need not even refer to any tables. The following\nexample defines a view that selects two columns from another table, as\nwell as an expression calculated from those columns:\n\nmysql> CREATE TABLE t (qty INT, price INT);\nmysql> INSERT INTO t VALUES(3, 50);\nmysql> CREATE VIEW v AS SELECT qty, price, qty*price AS value FROM t;\nmysql> SELECT * FROM v;\n+------+-------+-------+\n| qty | price | value |\n+------+-------+-------+\n| 3 | 50 | 150 |\n+------+-------+-------+\n\nA view definition is subject to the following restrictions:\n\no The SELECT statement cannot contain a subquery in the FROM clause.\n\no The SELECT statement cannot refer to system or user variables.\n\no Within a stored program, the definition cannot refer to program\n parameters or local variables.\n\no The SELECT statement cannot refer to prepared statement parameters.\n\no Any table or view referred to in the definition must exist. However,\n after a view has been created, it is possible to drop a table or view\n that the definition refers to. In this case, use of the view results\n in an error. To check a view definition for problems of this kind,\n use the CHECK TABLE statement.\n\no The definition cannot refer to a TEMPORARY table, and you cannot\n create a TEMPORARY view.\n\no Any tables named in the view definition must exist at definition\n time.\n\no You cannot associate a trigger with a view.\n\no As of MySQL 5.1.23, aliases for column names in the SELECT statement\n are checked against the maximum column length of 64 characters (not\n the maximum alias length of 256 characters).\n\nORDER BY is allowed in a view definition, but it is ignored if you\nselect from a view using a statement that has its own ORDER BY.\n\nFor other options or clauses in the definition, they are added to the\noptions or clauses of the statement that references the view, but the\neffect is undefined. For example, if a view definition includes a LIMIT\nclause, and you select from the view using a statement that has its own\nLIMIT clause, it is undefined which limit applies. This same principle\napplies to options such as ALL, DISTINCT, or SQL_SMALL_RESULT that\nfollow the SELECT keyword, and to clauses such as INTO, FOR UPDATE,\nLOCK IN SHARE MODE, and PROCEDURE.\n\nIf you create a view and then change the query processing environment\nby changing system variables, that may affect the results that you get\nfrom the view:\n\nmysql> CREATE VIEW v (mycol) AS SELECT \'abc\';\nQuery OK, 0 rows affected (0.01 sec)\n\nmysql> SET sql_mode = \'\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| mycol |\n+-------+\n1 row in set (0.01 sec)\n\nmysql> SET sql_mode = \'ANSI_QUOTES\';\nQuery OK, 0 rows affected (0.00 sec)\n\nmysql> SELECT "mycol" FROM v;\n+-------+\n| mycol |\n+-------+\n| abc |\n+-------+\n1 row in set (0.00 sec)\n\nThe DEFINER and SQL SECURITY clauses determine which MySQL account to\nuse when checking access privileges for the view when a statement is\nexecuted that references the view. They were addded in MySQL 5.1.2. The\nlegal SQL SECURITY characteristic values are DEFINER and INVOKER. These\nindicate that the required privileges must be held by the user who\ndefined or invoked the view, respectively. The default SQL SECURITY\nvalue is DEFINER.\n\nIf a user value is given for the DEFINER clause, it should be a MySQL\naccount in \'user_name\'@\'host_name\' format (the same format used in the\nGRANT statement). The user_name and host_name values both are required.\nThe definer can also be given as CURRENT_USER or CURRENT_USER(). The\ndefault DEFINER value is the user who executes the CREATE VIEW\nstatement. This is the same as specifying DEFINER = CURRENT_USER\nexplicitly.\n\nIf you specify the DEFINER clause, these rules determine the legal\nDEFINER user values:\n\no If you do not have the SUPER privilege, the only legal user value is\n your own account, either specified literally or by using\n CURRENT_USER. You cannot set the definer to some other account.\n\no If you have the SUPER privilege, you can specify any syntactically\n legal account name. If the account does not actually exist, a warning\n is generated.\n\no If the SQL SECURITY value is DEFINER but the definer account does not\n exist when the view is referenced, an error occurs.\n\nWithin a view definition, CURRENT_USER returns the view\'s DEFINER value\nby default as of MySQL 5.1.12. For older versions, and for views\ndefined with the SQL SECURITY INVOKER characteristic, CURRENT_USER\nreturns the account for the view\'s invoker. For information about user\nauditing within views, see\nhttp://dev.mysql.com/doc/refman/5.1/en/account-activity-auditing.html.… a stored routine that is defined with the SQL SECURITY DEFINER\ncharacteristic, CURRENT_USER returns the routine\'s DEFINER value. This\nalso affects a view defined within such a program, if the view\ndefinition contains a DEFINER value of CURRENT_USER.\n\nAs of MySQL 5.1.2 (when the DEFINER and SQL SECURITY clauses were\nimplemented), view privileges are checked like this:\n\no At view definition time, the view creator must have the privileges\n needed to use the top-level objects accessed by the view. For\n example, if the view definition refers to table columns, the creator\n must have privileges for the columns, as described previously. If the\n definition refers to a stored function, only the privileges needed to\n invoke the function can be checked. The privileges required when the\n function runs can be checked only as it executes: For different\n invocations of the function, different execution paths within the\n function might be taken.\n\no When a view is referenced, privileges for objects accessed by the\n view are checked against the privileges held by the view creator or\n invoker, depending on whether the SQL SECURITY characteristic is\n DEFINER or INVOKER, respectively.\n\no If reference to a view causes execution of a stored function,\n privilege checking for statements executed within the function depend\n on whether the function is defined with a SQL SECURITY characteristic\n of DEFINER or INVOKER. If the security characteristic is DEFINER, the\n function runs with the privileges of its creator. If the\n characteristic is INVOKER, the function runs with the privileges\n determined by the view\'s SQL SECURITY characteristic.\n\nPrior to MySQL 5.1.2 (before the DEFINER and SQL SECURITY clauses were\nimplemented), privileges required for objects used in a view are\nchecked at view creation time.\n\nExample: A view might depend on a stored function, and that function\nmight invoke other stored routines. For example, the following view\ninvokes a stored function f():\n\nCREATE VIEW v AS SELECT * FROM t WHERE t.id = f(t.name);\n\nSuppose that f() contains a statement such as this:\n\nIF name IS NULL then\n CALL p1();\nELSE\n CALL p2();\nEND IF;\n\nThe privileges required for executing statements within f() need to be\nchecked when f() executes. This might mean that privileges are needed\nfor p1() or p2(), depending on the execution path within f(). Those\nprivileges must be checked at runtime, and the user who must possess\nthe privileges is determined by the SQL SECURITY values of the view v\nand the function f().\n\nThe DEFINER and SQL SECURITY clauses for views are extensions to\nstandard SQL. In standard SQL, views are handled using the rules for\nSQL SECURITY INVOKER.\n\nIf you invoke a view that was created before MySQL 5.1.2, it is treated\nas though it was created with a SQL SECURITY DEFINER clause and with a\nDEFINER value that is the same as your account. However, because the\nactual definer is unknown, MySQL issues a warning. To make the warning\ngo away, it is sufficient to re-create the view so that the view\ndefinition includes a DEFINER clause.\n\nThe optional ALGORITHM clause is a MySQL extension to standard SQL. It\naffects how MySQL processes the view. ALGORITHM takes three values:\nMERGE, TEMPTABLE, or UNDEFINED. The default algorithm is UNDEFINED if\nno ALGORITHM clause is present. For more information, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-algorithms.html.\n\nSome views are updatable. That is, you can use them in statements such\nas UPDATE, DELETE, or INSERT to update the contents of the underlying\ntable. For a view to be updatable, there must be a one-to-one\nrelationship between the rows in the view and the rows in the\nunderlying table. There are also certain other constructs that make a\nview nonupdatable.\n\nThe WITH CHECK OPTION clause can be given for an updatable view to\nprevent inserts or updates to rows except those for which the WHERE\nclause in the select_statement is true.\n\nIn a WITH CHECK OPTION clause for an updatable view, the LOCAL and\nCASCADED keywords determine the scope of check testing when the view is\ndefined in terms of another view. The LOCAL keyword restricts the CHECK\nOPTION only to the view being defined. CASCADED causes the checks for\nunderlying views to be evaluated as well. When neither keyword is\ngiven, the default is CASCADED.\n\nFor more information about updatable views and the WITH CHECK OPTION\nclause, see\nhttp://dev.mysql.com/doc/refman/5.1/en/view-updatability.html.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/create-view.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/create-view.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (453,35,'TRIM','Syntax:\nTRIM([{BOTH | LEADING | TRAILING} [remstr] FROM] str), TRIM([remstr\nFROM] str)\n\nReturns the string str with all remstr prefixes or suffixes removed.

This is a common situation\nwhen you use MySQL for logging and you also periodically run SELECT and\nUPDATE statements that take a long time to complete.\n\nWhen a client uses INSERT DELAYED, it gets an okay from the server at\nonce, and the row is queued to be inserted when the table is not in use\nby any other thread.\n\nAnother major benefit of using INSERT DELAYED is that inserts from many\nclients are bundled together and written in one block. This is much\nfaster than performing many separate inserts.\n\nNote that INSERT DELAYED is slower than a normal INSERT if the table is\nnot otherwise in use. There is also the additional overhead for the\nserver to handle a separate thread for each table for which there are\ndelayed rows. This means that you should use INSERT DELAYED only when\nyou are really sure that you need it.\n\nThe queued rows are held only in memory until they are inserted into\nthe table. This means that if you terminate mysqld forcibly (for\nexample, with kill -9) or if mysqld dies unexpectedly, any queued rows\nthat have not been written to disk are lost.\n\nThere are some constraints on the use of DELAYED:\n\no INSERT DELAYED works only with MyISAM, MEMORY, ARCHIVE, and (as of\n MySQL 5.1.19) BLACKHOLE tables. For engines that do not support\n DELAYED, an error occurs.\n\no An error occurs for INSERT DELAYED if used with a table that has been\n locked with LOCK TABLES because the insert must be handled by a\n separate thread, not by the session that holds the lock.\n\no For MyISAM tables, if there are no free blocks in the middle of the\n data file, concurrent SELECT and INSERT statements are supported.\n Under these circumstances, you very seldom need to use INSERT DELAYED\n with MyISAM.\n\no INSERT DELAYED should be used only for INSERT statements that specify\n value lists. The server ignores DELAYED for INSERT ... SELECT or\n INSERT ... ON DUPLICATE KEY UPDATE statements.\n\no Because the INSERT DELAYED statement returns immediately, before the\n rows are inserted, you cannot use LAST_INSERT_ID() to get the\n AUTO_INCREMENT value that the statement might generate.\n\no DELAYED rows are not visible to SELECT statements until they actually\n have been inserted.\n\no INSERT DELAYED is treated as a normal INSERT if the statement inserts\n multiple rows and binary logging is enabled and the global logging\n format is to use statement-based logging (binlog_format is set to\n STATEMENT). This restriction does not apply to row-based binary\n logging.\n\no DELAYED is ignored on slave replication servers, so that INSERT\n DELAYED is treated as a normal INSERT on slaves. This is because\n DELAYED could cause the slave to have different data than the master.\n\no Pending INSERT DELAYED statements are lost if a table is write locked\n and ALTER TABLE is used to modify the table structure.\n\no INSERT DELAYED is not supported for views.\n\no INSERT DELAYED is not supported for partitioned tables.\n\nURL: http://dev.mysql.com/doc/refman/5.1/en/insert-delayed.html\n\n','','http://dev.mysql.com/doc/refman/5.1/en/insert-delayed.html'); +insert into help_topic (help_topic_id,help_category_id,name,description,example,url) values (483,25,'SHOW PROFILE','Syntax:\nSHOW PROFILES\n\nThe SHOW PROFILE statement display profiling information that indicates\nresource usage for statements executed during the course of the current\nsession.

A --engine=<storage_engine>:<option> was not always properly parsed and in some cases crashed. Fixed by eliminating "set storage_engine = ..." and adding proper DDL generation. Initialized an unitialized buffer to prevent crashes and fixed to use proper pointer for in case of --engine=<storage_engine>:<option> being the last element in list of --engines. Also cleaned up code for better readability. Q: Should MySQL's replication actually replicate a "set storage_engine = ..." command or not? A: No it should not. It is documented here: http://dev.mysql.com/doc/refman/5.1/en/replication-features-variables.html ...

If one is using statement-based replication, he can achieve this by grepping out "USE dbname" statements out of the output of mysqlbinlog(*). With row-based replication this is no longer possible, as database name is encoded within the the BINLOG '....' statement. This task is about adding an option to mysqlbinlog that would allow to change the names of used databases in both RBR and SBR events. (*) this implies that all statements refer to tables in the current database, doesn't catch updates made inside stored functions and so forth, but still works for a practially-important subset of cases. HIGH-LEVEL SPECIFICATION: Context ------- (See http://askmonty.org/wiki/index.php/Scratch/ReplicationOptions for global overview) At the moment, the server has a replication slave option --replicate-rewrite-db="from->to" the option affects - Table_map_log_event (all RBR events) - Load_log_event (LOAD DATA) - Query_log_event (SBR-based updates, with the usual assumption that the statement refers to tables in current database, so that changing the current database will make the statement to work on a table in a different database). See also MySQL BUG#42941. Note this bug is fixed in MySQL 5.1.37, which is not merged into MariaDB at the time of writing, but planned to be merged before release. What we could do ---------------- Option1: make mysqlbinlog accept --replicate-rewrite-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Make mysqlbinlog accept --replicate-rewrite-db options and process them to the same extent as replication slave would process --replicate-rewrite-db option. Option2: Add database-agnostic RBR events and --strip-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Right now RBR events require a databasename. It is not possible to have RBR event stream that won't mention which database the events are for. When I tried to use debugger and specify empty database name, attempt to apply the binlog resulted in this error: 090809 17:38:44 [ERROR] Slave SQL: Error 'Table '.tablename' doesn't exist' on opening tables, We could do as follows: - Make the server interpret empty database name in RBR event (i.e. in a Table_map_log_event) as "use current database". Binlog slave thread probably should not allow such events as it doesn't have a natural current database. - Add a mysqlbinlog --strip-db option that would = not produce any "USE dbname" statements = change databasename for all RBR events to be empty That way, mysqlbinlog output will be database-agnostic and apply to the current database. (this will have the usual limitations that we assume that all statements in the binlog refer to the current database). Option3: Enhance database rewrite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If there is a need to support database change for statements that use dbname.tablename notation and are replicated as statements (i.e. are DDL statements and/or DML statements that are binlogged as statements), then that could be supported as follows: - Make the server's parser recognize special form of comments /* !database-alias(oldname,newname) */ and save the mapping somewhere - Put the hooks in table open and name resolution code to use the saved mapping. Once we've done the above, it will be easy to perform a complete, no-compromise or restrictions database name change in binary log. It will be possible to do the rewrites either on the slave ( --replicate-rewrite-db will work for all kinds of statements), or in mysqlbinlog (adding a comment is easy and doesn't require mysqlbinlog to parse the statement). LOW-LEVEL DESIGN: Content ------- 1. Adding rewrite-db option 2. Supporting rewrite-db option for RBR events 3. Supporting rewrite-db option for SBR events (Limited to affecting only USE statements) 4. Current status 1. Adding rewrite-db option --------------------------- 1.1. Syntax: --rewrite-db='db_from->db_to' 1.2. Add 'OPT_REWRITE_DB' to 'options_client' (in client_priv.h). 1.3. In mysqlbinlog.cc: - Add { "rewrite-db", OPT_REWRITE_DB, ...} record to my_long_options: - Add Rpl_filter object to mysqlbinlog.cc Rpl_filter* binlog_filter; - Add corresponding switch case to get_one_option(): case OPT_REWRITE_DB: <extract db-from and db-to strings> binlog_filter->add_db_rewrite(db_from, db_to); break; . Note. To make Rpl_filter usable in a MYSQL_CLIENT context, few small additional changes are required: - In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) uses sql_alloc() which is THD dependent. These are to be modified as follows: #ifdef MYSQL_CLIENT extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc #endif class Sql_alloc { ... static void *operator new(size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } static void *operator new[](size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } ... } - In rpl_filter.cc: Rpl_filter::Rpl_filter() : ... { #ifdef MYSQL_CLIENT init_alloc_root(&sql_list_client_mem_root, ...); #endif ... } Rpl_filter::~Rpl_filter() { ... #ifdef MYSQL_CLIENT free_root(&sql_list_client_mem_root, ...); #endif } 2. Supporting rewrite-db for RBR events --------------------------------------- In binlog, each row operation event is preceded by Table map event(s) which maps table id(s) to database and table names. So, it's enough to support rewriting database name in a Table map. 2.1. Add rewrite_db() member to Table_map_log_event: int Table_map_log_event::rewrite_db( const char* new_db, size_t new_db_len, const Format_description_log_event* desc) { /* 1. In temp_buf member (possibly reallocating it) rewrite event length, db length, and db parts 2. Change m_dblen and m_dbnam members */ } Comment. This function assumes that temp_buf member contains Table map binlog representaion (temp_buf is used for creating corresponding BINLOG statement). 2.2. In mysqlbinlog modify corresponding switch case in the process_event() function: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { ... case TABLE_MAP_EVENT: { Table_map_log_event *map= ((Table_map_log_event *)ev); if (shall_skip_database(map->get_db_name())) { ... } // WL36 size_t new_len= 0; const char* new_db= binlog_filter->get_rewrite_db( map->get_db_name(), &new_len); if (new_len && map->rewrite_db(new_db, new_len, glob_description_event)) { error("Could not rewrite database name"); goto err; } } case WRITE_ROWS_EVENT: case DELETE_ROWS_EVENT: case UPDATE_ROWS_EVENT: ... } ... } Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains a (db_from, db_to) pair, this function returns pointer to db_to and sets len = db_to length; otherwise, it returns db_from and does not change len value. 3. Supporting rewrite-db for SBR events --------------------------------------- Limited to emiting USE <db_to> instead of USE <db_from>. USE statements can be emited by mysqlbinlog as a result of processing the following events (see process_event() function): - Query_log_event - Load_log_event - Execute_load_query_log_event [ :public Query_log_event ] - Create_file_log_event [ :public Load_log_event ] TODO. Needed to check this list carefully (not sure for Create_file_log_event) Notes. - In replication, only Query_log_event and Load_log_event uses rpl_filter->get_rewrite_db(); - In mysqlbinlog (process_event), Execute_load_query_log_event and Create_file_log_event are processed in separate switch cases. And Load_log_event is processed in the default switch case. Conditions for emiting use-statement: - LOG_EVENT_SUPPRESS_USE_F is OFF for the event (e.g. it is ON for 'create database' statement) - event's db name differs from db_name in PRINT_EVENT_INFO (PRINT_EVENT_INFO keeps db name of the last issued USE statement; initially, this db name is empty). 3.1. In mysqlbinlog.cc - Add the following function: void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) { if (event->flags & LOG_EVENT_SUPPRESS_USE_F) return; /* - For events listed above get db_from = event->db; - If db_from is the same as pinfo->db then return; - If there is rewrite-db rule db_from->db_to, set db = db_to. Else set db = db_from; - Print "use <db>" to mysqlbinlog output - Set pinfo->db = db_from (this suppresses emiting use-statements by corresponding log_event's print-function) */ } - In process_event() function add switch case for Load_log_event and add print_use_stmt() invocations where needed (according to the events list above), e.g.: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { case QUERY_EVENT: if (shall_skip_database(((Query_log_event*)ev)->db)) goto end; if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) { // Possibly in case of rewite-db rule for ev->db // a warning should be emited here (see note below) ... write_event_header_and_base64(ev, ...) ... } else { print_use_stmt((Query_log_event*)ev, print_event_info); ev->print(result_file, print_event_info); } break; ... case LOAD_EVENT: print_use_stmt((Load_log_event*)ev, print_event_info); break; default: ... } ... } Note. write_event_header_and_base64() does not print use-statement. It produces BINLOG statement using ev->temp_buf content (i.e. the binary log representation of the event). We don't rewrite temp_buf here with db_to name (as we do it for Table map event) - this implies the limitation 3 mentioned above. Question: Is supporting of rewite_db + --base64-output really needed currently? 4. Current status ----------------- The outlined design (implemented for mysql-5.1.37) is tested for simple test-cases. TODO. 1. Check list of events which can emit use-statement. 2. Supporting of rewite_db + --base64-output ? ESTIMATED WORK TIME ESTIMATED COMPLETION DATE ----------------------------------------------------------------------- WorkLog (v3.5.9)

A --engine=<storage_engine>:<option> was not always properly parsed and in some cases crashed. Fixed by eliminating "set storage_engine = ..." and adding proper DDL generation. Initialized an unitialized buffer to prevent crashes and fixed to use proper pointer for in case of --engine=<storage_engine>:<option> being the last element in list of --engines. Also cleaned up code for better readability. Q: Should MySQL's replication actually replicate a "set storage_engine = ..." command or not? A: No it should not.

A --engine=<storage_engine>:<option> was not always properly parsed and in some cases crashed. Fixed by eliminating "set storage_engine = ..." and adding proper DDL generation. Initialized an unitialized buffer to prevent crashes and fixed to use proper pointer for in case of --engine=<storage_engine>:<option> being the last element in list of --engines. Also cleaned up code for better readability. Q: Should MySQL's replication actually replicate a "set storage_engine = ..." command or not? A: No it should not. It is documented here: http://dev.mysql.com/doc/refman/5.1/en/replication-features-variables.html ... "The storage_engine system variable is not replicated, which is a good thing for replication between different storage engines." ...

If one is using statement-based replication, he can achieve this by grepping out "USE dbname" statements out of the output of mysqlbinlog(*). With row-based replication this is no longer possible, as database name is encoded within the the BINLOG '....' statement. This task is about adding an option to mysqlbinlog that would allow to change the names of used databases in both RBR and SBR events. (*) this implies that all statements refer to tables in the current database, doesn't catch updates made inside stored functions and so forth, but still works for a practially-important subset of cases. HIGH-LEVEL SPECIFICATION: Context ------- (See http://askmonty.org/wiki/index.php/Scratch/ReplicationOptions for global overview) At the moment, the server has a replication slave option --replicate-rewrite-db="from->to" the option affects - Table_map_log_event (all RBR events) - Load_log_event (LOAD DATA) - Query_log_event (SBR-based updates, with the usual assumption that the statement refers to tables in current database, so that changing the current database will make the statement to work on a table in a different database). See also MySQL BUG#42941. Note this bug is fixed in MySQL 5.1.37, which is not merged into MariaDB at the time of writing, but planned to be merged before release. What we could do ---------------- Option1: make mysqlbinlog accept --replicate-rewrite-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Make mysqlbinlog accept --replicate-rewrite-db options and process them to the same extent as replication slave would process --replicate-rewrite-db option. Option2: Add database-agnostic RBR events and --strip-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Right now RBR events require a databasename. It is not possible to have RBR event stream that won't mention which database the events are for. When I tried to use debugger and specify empty database name, attempt to apply the binlog resulted in this error: 090809 17:38:44 [ERROR] Slave SQL: Error 'Table '.tablename' doesn't exist' on opening tables, We could do as follows: - Make the server interpret empty database name in RBR event (i.e. in a Table_map_log_event) as "use current database". Binlog slave thread probably should not allow such events as it doesn't have a natural current database. - Add a mysqlbinlog --strip-db option that would = not produce any "USE dbname" statements = change databasename for all RBR events to be empty That way, mysqlbinlog output will be database-agnostic and apply to the current database. (this will have the usual limitations that we assume that all statements in the binlog refer to the current database). Option3: Enhance database rewrite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If there is a need to support database change for statements that use dbname.tablename notation and are replicated as statements (i.e. are DDL statements and/or DML statements that are binlogged as statements), then that could be supported as follows: - Make the server's parser recognize special form of comments /* !database-alias(oldname,newname) */ and save the mapping somewhere - Put the hooks in table open and name resolution code to use the saved mapping. Once we've done the above, it will be easy to perform a complete, no-compromise or restrictions database name change in binary log. It will be possible to do the rewrites either on the slave ( --replicate-rewrite-db will work for all kinds of statements), or in mysqlbinlog (adding a comment is easy and doesn't require mysqlbinlog to parse the statement). LOW-LEVEL DESIGN: Content ------- 1. Adding rewrite-db option 2. Supporting rewrite-db option for RBR events 3. Supporting rewrite-db option for SBR events (Limited to affecting only USE statements) 4. Current status 1. Adding rewrite-db option --------------------------- 1.1. Syntax: --rewrite-db='db_from->db_to' 1.2. Add 'OPT_REWRITE_DB' to 'options_client' (in client_priv.h). 1.3. In mysqlbinlog.cc: - Add { "rewrite-db", OPT_REWRITE_DB, ...} record to my_long_options: - Add Rpl_filter object to mysqlbinlog.cc Rpl_filter* binlog_filter; - Add corresponding switch case to get_one_option(): case OPT_REWRITE_DB: <extract db-from and db-to strings> binlog_filter->add_db_rewrite(db_from, db_to); break; . Note. To make Rpl_filter usable in a MYSQL_CLIENT context, few small additional changes are required: - In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) uses sql_alloc() which is THD dependent. These are to be modified as follows: #ifdef MYSQL_CLIENT extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc #endif class Sql_alloc { ... static void *operator new(size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } static void *operator new[](size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } ... } - In rpl_filter.cc: Rpl_filter::Rpl_filter() : ... { #ifdef MYSQL_CLIENT init_alloc_root(&sql_list_client_mem_root, ...); #endif ... } Rpl_filter::~Rpl_filter() { ... #ifdef MYSQL_CLIENT free_root(&sql_list_client_mem_root, ...); #endif } 2. Supporting rewrite-db for RBR events --------------------------------------- In binlog, each row operation event is preceded by Table map event(s) which maps table id(s) to database and table names. So, it's enough to support rewriting database name in a Table map. 2.1. Add rewrite_db() member to Table_map_log_event: int Table_map_log_event::rewrite_db( const char* new_db, size_t new_db_len, const Format_description_log_event* desc) { /* 1. In temp_buf member (possibly reallocating it) rewrite event length, db length, and db parts 2. Change m_dblen and m_dbnam members */ } Comment. This function assumes that temp_buf member contains Table map binlog representaion (temp_buf is used for creating corresponding BINLOG statement). 2.2. In mysqlbinlog modify corresponding switch case in the process_event() function: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { ... case TABLE_MAP_EVENT: { Table_map_log_event *map= ((Table_map_log_event *)ev); if (shall_skip_database(map->get_db_name())) { ... } // WL36 size_t new_len= 0; const char* new_db= binlog_filter->get_rewrite_db( map->get_db_name(), &new_len); if (new_len && map->rewrite_db(new_db, new_len, glob_description_event)) { error("Could not rewrite database name"); goto err; } } case WRITE_ROWS_EVENT: case DELETE_ROWS_EVENT: case UPDATE_ROWS_EVENT: ... } ... } Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains a (db_from, db_to) pair, this function returns pointer to db_to and sets len = db_to length; otherwise, it returns db_from and does not change len value. 3. Supporting rewrite-db for SBR events --------------------------------------- Limited to emiting USE <db_to> instead of USE <db_from>. USE statements can be emited by mysqlbinlog as a result of processing the following events (see process_event() function): - Query_log_event - Load_log_event - Execute_load_query_log_event [ :public Query_log_event ] - Create_file_log_event [ :public Load_log_event ] TODO. Needed to check this list carefully (not sure for Create_file_log_event) Notes. - In replication, only Query_log_event and Load_log_event uses rpl_filter->get_rewrite_db(); - In mysqlbinlog (process_event), Execute_load_query_log_event and Create_file_log_event are processed in separate switch cases. And Load_log_event is processed in the default switch case. Conditions for emiting use-statement: - LOG_EVENT_SUPPRESS_USE_F is OFF for the event (e.g. it is ON for 'create database' statement) - event's db name differs from db_name in PRINT_EVENT_INFO (PRINT_EVENT_INFO keeps db name of the last issued USE statement; initially, this db name is empty). 3.1. In mysqlbinlog.cc - Add the following function: void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) { if (event->flags & LOG_EVENT_SUPPRESS_USE_F) return; /* - For events listed above get db_from = event->db; - If db_from is the same as pinfo->db then return; - If there is rewrite-db rule db_from->db_to, set db = db_to. Else set db = db_from; - Print "use <db>" to mysqlbinlog output - Set pinfo->db = db_from (this suppresses emiting use-statements by corresponding log_event's print-function) */ } - In process_event() function add switch case for Load_log_event and add print_use_stmt() invocations where needed (according to the events lis above), e.g.: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { case QUERY_EVENT: if (shall_skip_database(((Query_log_event*)ev)->db)) goto end; if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) { // Possibly in case of rewite-db rule for ev->db // a warning should be emited here (see note below) ... write_event_header_and_base64(ev, ...) ... } else { print_use_stmt((Query_log_event*)ev, print_event_info); ev->print(result_file, print_event_info); } break; ... case LOAD_EVENT: print_use_stmt((Load_log_event*)ev, print_event_info); break; default: ... } ... } Note. write_event_header_and_base64() does not print use-statement. It produces BINLOG statement using ev->temp_buf content (i.e. the binary log representation of the event). We don't rewrite temp_buf here with db_to name (as we do it for Table map event) - this implies the limitation 3 mentioned above. Question: Is supporting of rewite_db + --base64-output really needed currently? 4. Current status ----------------- The outlined design (implemented for mysql-5.1.37) is tested for simple test-cases. TODO. 1. Check list of events which can emit use-statement. 2. Supporting of rewite_db + --base64-output ? ESTIMATED WORK TIME ESTIMATED COMPLETION DATE ----------------------------------------------------------------------- WorkLog (v3.5.9)

[Maria-developers] Diff for stuff from MySQL 5.1.38 not yet included in the merge
by Kristian Nielsen 15 Sep '09

15 Sep '09

Hi Sergey, Here is the diff of the commits that are not yet merged from MySQL 5.1.38 (they are missing from our merge since they were not yet pushed to Launchpad by the MySQL build team when the merge was done by Jani and Monty). There is a Windows build one-liner, but don't know if it will help you. I will merge this into maria-5.1-merge as soon as you have pushed your merge with latest lp:maria. - Kristian. === modified file '.bzrignore' --- .bzrignore 2009-02-27 11:20:53 +0000 +++ .bzrignore 2009-08-12 20:06:44 +0000 @@ -3063,3 +3063,4 @@ sql/share/slovak sql/share/spanish sql/share/swedish sql/share/ukrainian +libmysqld/examples/mysqltest.cc === modified file 'CMakeLists.txt' --- CMakeLists.txt 2009-08-11 15:47:33 +0000 +++ CMakeLists.txt 2009-08-14 15:18:52 +0000 @@ -137,6 +137,7 @@ ENDIF(MSVC) IF(WIN32) ADD_DEFINITIONS("-D_WINDOWS -D__WIN__ -D_CRT_SECURE_NO_DEPRECATE") + ADD_DEFINITIONS("-D_WIN32_WINNT=0x0501") ENDIF(WIN32) # default to x86 platform.

[Maria-developers] diff of extra stuff included in out merge.
by Kristian Nielsen 15 Sep '09

15 Sep '09

Hi Sergey, Here is the diff of the extra stuff that Jani and Monty merged, but which is not included in MySQL-5.1.38. As can be seen, none of it really matters (except the version number; I'll fix that to be 5.1.38-maria-beta1). I suggest we just leave it in place to simplify future merges. Still, hopefully the next time we merge, we will make sure we merge some well-defined release of MySQL ;-) - Kristian. === modified file '.bzrignore' --- .bzrignore 2009-02-27 11:20:53 +0000 +++ .bzrignore 2009-08-12 19:45:01 +0000 @@ -3063,3 +3063,4 @@ sql/share/slovak sql/share/spanish sql/share/swedish sql/share/ukrainian +libmysqld/examples/mysqltest.cc === modified file 'configure.in' --- configure.in 2009-07-13 20:43:31 +0000 +++ configure.in 2009-08-13 20:33:00 +0000 @@ -10,7 +10,7 @@ AC_CANONICAL_SYSTEM # # When changing major version number please also check switch statement # in mysqlbinlog::check_master_version(). -AM_INIT_AUTOMAKE(mysql, 5.1.38) +AM_INIT_AUTOMAKE(mysql, 5.1.39) AM_CONFIG_HEADER([include/config.h:config.h.in]) PROTOCOL_VERSION=10 === modified file 'man/Makefile.am' --- man/Makefile.am 2008-08-27 14:03:39 +0000 +++ man/Makefile.am 2009-08-20 19:41:12 +0000 @@ -23,7 +23,7 @@ EXTRA_DIST = $(man1_MANS) $(man8_MANS) # "make_win_*" are not needed in Unix binary packages, install-data-hook: - rm -f $(DESTDIR)$(manlibdir)/man1/make_win_* + rm -f $(DESTDIR)$(mandir)/man1/make_win_* # Don't update the files from bitkeeper %::SCCS/s.% === modified file 'mysql-test/collections/default.daily' --- mysql-test/collections/default.daily 2009-02-24 11:53:34 +0000 +++ mysql-test/collections/default.daily 2009-08-12 15:10:15 +0000 @@ -1 +1 @@ -perl mysql-test-run.pl --timer --force --comment=rpl_ndb_row --suite=rpl_ndb,ndb --mysqld=--binlog-format=row --experimental=collections/default.experimental +perl mysql-test-run.pl --timer --force --comment=rpl_ndb_row --vardir=var-rpl_ndb_row --suite=rpl_ndb,ndb --mysqld=--binlog-format=row --experimental=collections/default.experimental === modified file 'mysql-test/collections/default.push' --- mysql-test/collections/default.push 2009-06-03 10:46:04 +0000 +++ mysql-test/collections/default.push 2009-08-12 15:10:15 +0000 @@ -1,5 +1,5 @@ -perl mysql-test-run.pl --timer --force --parallel=auto --comment=n_mix --mysqld=--binlog-format=mixed --experimental=collections/default.experimental -perl mysql-test-run.pl --timer --force --parallel=auto --comment=ps_row --ps-protocol --mysqld=--binlog-format=row --experimental=collections/default.experimental -perl mysql-test-run.pl --timer --force --parallel=auto --comment=embedded --embedded --experimental=collections/default.experimental -perl mysql-test-run.pl --timer --force --parallel=auto --comment=rpl_binlog_row --suite=rpl,binlog --mysqld=--binlog-format=row --experimental=collections/default.experimental -perl mysql-test-run.pl --timer --force --parallel=auto --comment=funcs_1 --suite=funcs_1 --experimental=collections/default.experimental +perl mysql-test-run.pl --timer --force --parallel=auto --comment=n_mix --vardir=var-n_mix --mysqld=--binlog-format=mixed --experimental=collections/default.experimental +perl mysql-test-run.pl --timer --force --parallel=auto --comment=ps_row --vardir=var-ps_row --ps-protocol --mysqld=--binlog-format=row --experimental=collections/default.experimental +perl mysql-test-run.pl --timer --force --parallel=auto --comment=embedded --vardir=var-emebbed --embedded --experimental=collections/default.experimental +perl mysql-test-run.pl --timer --force --parallel=auto --comment=rpl_binlog_row --vardir=var-rpl_binlog_row --suite=rpl,binlog --mysqld=--binlog-format=row --experimental=collections/default.experimental +perl mysql-test-run.pl --timer --force --parallel=auto --comment=funcs_1 --vardir=var-funcs_1 --suite=funcs_1 --experimental=collections/default.experimental === modified file 'mysql-test/lib/mtr_cases.pm' --- mysql-test/lib/mtr_cases.pm 2009-07-30 12:42:56 +0000 +++ mysql-test/lib/mtr_cases.pm 2009-08-12 12:46:12 +0000 @@ -494,6 +494,7 @@ sub collect_one_suite($) next if ($test->{'skip'} || !$test->{'innodb_test'});

To make Rpl_filter usable in a MYSQL_CLIENT context, few small +additional changes are required: + +- In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) + uses sql_alloc() which is THD dependent. These are to be modified + as follows: + + #ifdef MYSQL_CLIENT + extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc + #endif + + class Sql_alloc + { ... + static void *operator new(size_t size) throw () + { + #ifndef MYSQL_CLIENT + return sql_alloc(size); + #else + return alloc_root(&sql_list_client_mem_root, size); + #endif + } + static void *operator new[](size_t size) throw () + { + #ifndef MYSQL_CLIENT + return sql_alloc(size); + #else + return alloc_root(&sql_list_client_mem_root, size); + #endif + } + ... + } + +- In rpl_filter.cc: + + Rpl_filter::Rpl_filter() : + ... + { + #ifdef MYSQL_CLIENT + init_alloc_root(&sql_list_client_mem_root, ...); + #endif + ... + } + + Rpl_filter::~Rpl_filter() + { ... + #ifdef MYSQL_CLIENT + free_root(&sql_list_client_mem_root, ...); + #endif + } + +2. Supporting rewrite-db for RBR events +--------------------------------------- + +In binlog, each row operation event is preceded by Table map event(s) which maps +table id(s) to database and table names. So, it's enough to support rewriting +database name in a Table map. + +2.1. Add rewrite_db() member to Table_map_log_event: + + int Table_map_log_event::rewrite_db( + const char* new_db, + size_t new_db_len, + const Format_description_log_event* desc) + { + /* 1. In temp_buf member (possibly reallocating it) rewrite + event length, db length, and db parts + 2. Change m_dblen and m_dbnam members + */ + } + +Comment. This function assumes that temp_buf member contains Table map +binlog representaion (temp_buf is used for creating corresponding +BINLOG statement). + +2.2. In mysqlbinlog modify corresponding switch case in the +process_event() function: + + Exit_status process_event( + PRINT_EVENT_INFO *print_event_info, + Log_event *ev, ...) + { + ... + switch (ev_type) { + ... + case TABLE_MAP_EVENT: + { + Table_map_log_event *map= ((Table_map_log_event *)ev); + if (shall_skip_database(map->get_db_name())) + { ... + } + // WL36 + size_t new_len= 0; + const char* new_db= binlog_filter->get_rewrite_db( + map->get_db_name(), &new_len); + if (new_len && map->rewrite_db(new_db, new_len, + glob_description_event)) + { error("Could not rewrite database name"); + goto err; + } + } + case WRITE_ROWS_EVENT: + case DELETE_ROWS_EVENT: + case UPDATE_ROWS_EVENT: + ... + } + ... + } + +Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains +a (db_from, db_to) pair, this function returns pointer to db_to and +sets len = db_to length; otherwise, it returns db_from and does not +change len value. + +3. Supporting rewrite-db for SBR events +--------------------------------------- + +USE statements can be emited by mysqlbinlog as a result of processing the +following events (see process_event() function): + +- Query_log_event +- Execute_load_query_log_event +- Create_file_log_event + +TODO. Needed to check this list requires carefully !!! + +Conditions for emiting use-statement: +- LOG_EVENT_SUPPRESS_USE_F is OFF for the event + (e.g. it is ON for 'create database' statement) +- event's db name differs from db_name in PRINT_EVENT_INFO + (PRINT_EVENT_INFO keeps db name of the last issued USE statement; + initially, this db name is empty). + +3.1. In mysqlbinlog.cc + +- Add the following function: + + void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) + { + if (event->flags & LOG_EVENT_SUPPRESS_USE_F) + return; + /* + - For events listed above get db_from = event->db; + - If db_from is the same as pinfo->db then return; + - If there is rewrite-db rule db_from->db_to, + set db = db_to. Else set db = db_from; + - Print "use <db>" to mysqlbinlog output + - Set pinfo->db = db_from + (this suppresses emiting use-statements by corresponding + log_event's print-function) + */ + } + +- In process_event() function add print_use_stmt() invocations where + needed (according to the events lis above), e.g.: + + Exit_status process_event( + PRINT_EVENT_INFO *print_event_info, + Log_event *ev, ...) + { + ... + switch (ev_type) { + case QUERY_EVENT: + if (shall_skip_database(((Query_log_event*)ev)->db)) + goto end; + if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) + { + // Possibly in case of rewite-db rule for ev->db + // a warning should be emited here (see note below) + ... write_event_header_and_base64(ev, ...) ... + } + else + { + print_use_stmt((Query_log_event*)ev, print_event_info); + ev->print(result_file, print_event_info); + } + break; + ... + } + ... + } + +Note. write_event_header_and_base64() does not print use-statement. It +produces BINLOG statement using ev->temp_buf content (i.e. the binary +log representation of the event). We don't rewrite temp_buf here with +db_to name (as we do it for Table map event) - this implies the +limitation 3 mentioned above. +Question: Is supporting of rewite_db + --base64-output really needed +currently? + +4.

If one is using statement-based replication, he can achieve this by grepping out "USE dbname" statements out of the output of mysqlbinlog(*). With row-based replication this is no longer possible, as database name is encoded within the the BINLOG '....' statement. This task is about adding an option to mysqlbinlog that would allow to change the names of used databases in both RBR and SBR events. (*) this implies that all statements refer to tables in the current database, doesn't catch updates made inside stored functions and so forth, but still works for a practially-important subset of cases. HIGH-LEVEL SPECIFICATION: Context ------- (See http://askmonty.org/wiki/index.php/Scratch/ReplicationOptions for global overview) At the moment, the server has a replication slave option --replicate-rewrite-db="from->to" the option affects - Table_map_log_event (all RBR events) - Load_log_event (LOAD DATA) - Query_log_event (SBR-based updates, with the usual assumption that the statement refers to tables in current database, so that changing the current database will make the statement to work on a table in a different database). See also MySQL BUG#42941. Note this bug is fixed in MySQL 5.1.37, which is not merged into MariaDB at the time of writing, but planned to be merged before release. What we could do ---------------- Option1: make mysqlbinlog accept --replicate-rewrite-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Make mysqlbinlog accept --replicate-rewrite-db options and process them to the same extent as replication slave would process --replicate-rewrite-db option. Option2: Add database-agnostic RBR events and --strip-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Right now RBR events require a databasename. It is not possible to have RBR event stream that won't mention which database the events are for. When I tried to use debugger and specify empty database name, attempt to apply the binlog resulted in this error: 090809 17:38:44 [ERROR] Slave SQL: Error 'Table '.tablename' doesn't exist' on opening tables, We could do as follows: - Make the server interpret empty database name in RBR event (i.e. in a Table_map_log_event) as "use current database". Binlog slave thread probably should not allow such events as it doesn't have a natural current database. - Add a mysqlbinlog --strip-db option that would = not produce any "USE dbname" statements = change databasename for all RBR events to be empty That way, mysqlbinlog output will be database-agnostic and apply to the current database. (this will have the usual limitations that we assume that all statements in the binlog refer to the current database). Option3: Enhance database rewrite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If there is a need to support database change for statements that use dbname.tablename notation and are replicated as statements (i.e. are DDL statements and/or DML statements that are binlogged as statements), then that could be supported as follows: - Make the server's parser recognize special form of comments /* !database-alias(oldname,newname) */ and save the mapping somewhere - Put the hooks in table open and name resolution code to use the saved mapping. Once we've done the above, it will be easy to perform a complete, no-compromise or restrictions database name change in binary log. It will be possible to do the rewrites either on the slave ( --replicate-rewrite-db will work for all kinds of statements), or in mysqlbinlog (adding a comment is easy and doesn't require mysqlbinlog to parse the statement). LOW-LEVEL DESIGN: Content ------- 1. Adding rewrite-db option 2. Supporting rewrite-db option for RBR events 3. Supporting rewrite-db option for SBR events (Limited to affecting only USE statements) 4. Current status 1. Adding rewrite-db option --------------------------- 1.1. Syntax: --rewrite-db='db_from->db_to' 1.2. Add 'OPT_REWRITE_DB' to 'options_client' (in client_priv.h). 1.3. In mysqlbinlog.cc: - Add { "rewrite-db", OPT_REWRITE_DB, ...} record to my_long_options: - Add Rpl_filter object to mysqlbinlog.cc Rpl_filter* binlog_filter; - Add corresponding switch case to get_one_option(): case OPT_REWRITE_DB: <extract db-from and db-to strings> binlog_filter->add_db_rewrite(db_from, db_to); break; . Note. To make Rpl_filter usable in a MYSQL_CLIENT context, few small additional changes are required: - In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) uses sql_alloc() which is THD dependent. These are to be modified as follows: #ifdef MYSQL_CLIENT extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc #endif class Sql_alloc { ... static void *operator new(size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } static void *operator new[](size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } ... } - In rpl_filter.cc: Rpl_filter::Rpl_filter() : ... { #ifdef MYSQL_CLIENT init_alloc_root(&sql_list_client_mem_root, ...); #endif ... } Rpl_filter::~Rpl_filter() { ... #ifdef MYSQL_CLIENT free_root(&sql_list_client_mem_root, ...); #endif } 2. Supporting rewrite-db for RBR events --------------------------------------- In binlog, each row operation event is preceded by Table map event(s) which maps table id(s) to database and table names. So, it's enough to support rewriting database name in a Table map. 2.1. Add rewrite_db() member to Table_map_log_event: int Table_map_log_event::rewrite_db( const char* new_db, size_t new_db_len, const Format_description_log_event* desc) { /* 1. In temp_buf member (possibly reallocating it) rewrite event length, db length, and db parts 2. Change m_dblen and m_dbnam members */ } Comment. This function assumes that temp_buf member contains Table map binlog representaion (temp_buf is used for creating corresponding BINLOG statement). 2.2. In mysqlbinlog modify corresponding switch case in the process_event() function: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { ... case TABLE_MAP_EVENT: { Table_map_log_event *map= ((Table_map_log_event *)ev); if (shall_skip_database(map->get_db_name())) { ... } // WL36 size_t new_len= 0; const char* new_db= binlog_filter->get_rewrite_db( map->get_db_name(), &new_len); if (new_len && map->rewrite_db(new_db, new_len, glob_description_event)) { error("Could not rewrite database name"); goto err; } } case WRITE_ROWS_EVENT: case DELETE_ROWS_EVENT: case UPDATE_ROWS_EVENT: ... } ... } Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains a (db_from, db_to) pair, this function returns pointer to db_to and sets len = db_to length; otherwise, it returns db_from and does not change len value. 3. Supporting rewrite-db for SBR events --------------------------------------- Limited to emiting USE <db_to> instead of USE <db_from>. USE statements can be emited by mysqlbinlog as a result of processing the following events (see process_event() function): - Query_log_event - Execute_load_query_log_event - Create_file_log_event TODO. Needed to check this list requires carefully !!! Conditions for emiting use-statement: - LOG_EVENT_SUPPRESS_USE_F is OFF for the event (e.g. it is ON for 'create database' statement) - event's db name differs from db_name in PRINT_EVENT_INFO (PRINT_EVENT_INFO keeps db name of the last issued USE statement; initially, this db name is empty). 3.1. In mysqlbinlog.cc - Add the following function: void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) { if (event->flags & LOG_EVENT_SUPPRESS_USE_F) return; /* - For events listed above get db_from = event->db; - If db_from is the same as pinfo->db then return; - If there is rewrite-db rule db_from->db_to, set db = db_to. Else set db = db_from; - Print "use <db>" to mysqlbinlog output - Set pinfo->db = db_from (this suppresses emiting use-statements by corresponding log_event's print-function) */ } - In process_event() function add print_use_stmt() invocations where needed (according to the events lis above), e.g.: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { case QUERY_EVENT: if (shall_skip_database(((Query_log_event*)ev)->db)) goto end; if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) { // Possibly in case of rewite-db rule for ev->db // a warning should be emited here (see note below) ... write_event_header_and_base64(ev, ...) ... } else { print_use_stmt((Query_log_event*)ev, print_event_info); ev->print(result_file, print_event_info); } break; ... } ... } Note. write_event_header_and_base64() does not print use-statement. It produces BINLOG statement using ev->temp_buf content (i.e. the binary log representation of the event). We don't rewrite temp_buf here with db_to name (as we do it for Table map event) - this implies the limitation 3 mentioned above. Question: Is supporting of rewite_db + --base64-output really needed currently? 4. Current status ----------------- The outlined design (implemented for mysql-5.1.37) is tested for simple test-cases. TODO. 1. Check list of events which can emit use-statement. 2. Supporting of rewite_db + --base64-output ?

If one is using statement-based replication, he can achieve this by grepping out "USE dbname" statements out of the output of mysqlbinlog(*). With row-based replication this is no longer possible, as database name is encoded within the the BINLOG '....' statement. This task is about adding an option to mysqlbinlog that would allow to change the names of used databases in both RBR and SBR events. (*) this implies that all statements refer to tables in the current database, doesn't catch updates made inside stored functions and so forth, but still works for a practially-important subset of cases. HIGH-LEVEL SPECIFICATION: Context ------- (See http://askmonty.org/wiki/index.php/Scratch/ReplicationOptions for global overview) At the moment, the server has a replication slave option --replicate-rewrite-db="from->to" the option affects - Table_map_log_event (all RBR events) - Load_log_event (LOAD DATA) - Query_log_event (SBR-based updates, with the usual assumption that the statement refers to tables in current database, so that changing the current database will make the statement to work on a table in a different database). See also MySQL BUG#42941. Note this bug is fixed in MySQL 5.1.37, which is not merged into MariaDB at the time of writing, but planned to be merged before release. What we could do ---------------- Option1: make mysqlbinlog accept --replicate-rewrite-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Make mysqlbinlog accept --replicate-rewrite-db options and process them to the same extent as replication slave would process --replicate-rewrite-db option. Option2: Add database-agnostic RBR events and --strip-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Right now RBR events require a databasename. It is not possible to have RBR event stream that won't mention which database the events are for. When I tried to use debugger and specify empty database name, attempt to apply the binlog resulted in this error: 090809 17:38:44 [ERROR] Slave SQL: Error 'Table '.tablename' doesn't exist' on opening tables, We could do as follows: - Make the server interpret empty database name in RBR event (i.e. in a Table_map_log_event) as "use current database". Binlog slave thread probably should not allow such events as it doesn't have a natural current database. - Add a mysqlbinlog --strip-db option that would = not produce any "USE dbname" statements = change databasename for all RBR events to be empty That way, mysqlbinlog output will be database-agnostic and apply to the current database. (this will have the usual limitations that we assume that all statements in the binlog refer to the current database). Option3: Enhance database rewrite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If there is a need to support database change for statements that use dbname.tablename notation and are replicated as statements (i.e. are DDL statements and/or DML statements that are binlogged as statements), then that could be supported as follows: - Make the server's parser recognize special form of comments /* !database-alias(oldname,newname) */ and save the mapping somewhere - Put the hooks in table open and name resolution code to use the saved mapping. Once we've done the above, it will be easy to perform a complete, no-compromise or restrictions database name change in binary log. It will be possible to do the rewrites either on the slave ( --replicate-rewrite-db will work for all kinds of statements), or in mysqlbinlog (adding a comment is easy and doesn't require mysqlbinlog to parse the statement). LOW-LEVEL DESIGN: Content ------- 1. Adding rewrite-db option 2. Supporting rewrite-db option for RBR events 3. Supporting rewrite-db option for SBR events (Limited to affecting only USE statements) 4. Current status 1. Adding rewrite-db option --------------------------- 1.1. Syntax: --rewrite-db='db_from->db_to' 1.2. Add 'OPT_REWRITE_DB' to 'options_client' (in client_priv.h). 1.3. In mysqlbinlog.cc: - Add { "rewrite-db", OPT_REWRITE_DB, ...} record to my_long_options: - Add Rpl_filter object to mysqlbinlog.cc Rpl_filter* binlog_filter; - Add corresponding switch case to get_one_option(): case OPT_REWRITE_DB: <extract db-from and db-to strings> binlog_filter->add_db_rewrite(db_from, db_to); break; . Note. To make Rpl_filter usable in a MYSQL_CLIENT context, few small additional changes are required: - In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) uses sql_alloc() which is THD dependent. These are to be modified as follows: #ifdef MYSQL_CLIENT extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc #endif class Sql_alloc { ... static void *operator new(size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } static void *operator new[](size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } ... } - In rpl_filter.cc: Rpl_filter::Rpl_filter() : ... { #ifdef MYSQL_CLIENT init_alloc_root(&sql_list_client_mem_root, ...); #endif ... } Rpl_filter::~Rpl_filter() { ... #ifdef MYSQL_CLIENT free_root(&sql_list_client_mem_root, ...); #endif } 2. Supporting rewrite-db for RBR events --------------------------------------- In binlog, each row operation event is preceded by Table map event(s) which maps table id(s) to database and table names. So, it's enough to support rewriting database name in a Table map. 2.1. Add rewrite_db() member to Table_map_log_event: int Table_map_log_event::rewrite_db( const char* new_db, size_t new_db_len, const Format_description_log_event* desc) { /* 1. In temp_buf member (possibly reallocating it) rewrite event length, db length, and db parts 2. Change m_dblen and m_dbnam members */ } Comment. This function assumes that temp_buf member contains Table map binlog representaion (temp_buf is used for creating corresponding BINLOG statement). 2.2. In mysqlbinlog modify corresponding switch case in the process_event() function: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { ... case TABLE_MAP_EVENT: { Table_map_log_event *map= ((Table_map_log_event *)ev); if (shall_skip_database(map->get_db_name())) { ... } // WL36 size_t new_len= 0; const char* new_db= binlog_filter->get_rewrite_db( map->get_db_name(), &new_len); if (new_len && map->rewrite_db(new_db, new_len, glob_description_event)) { error("Could not rewrite database name"); goto err; } } case WRITE_ROWS_EVENT: case DELETE_ROWS_EVENT: case UPDATE_ROWS_EVENT: ... } ... } Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains a (db_from, db_to) pair, this function returns pointer to db_to and sets len = db_to length; otherwise, it returns db_from and does not change len value. 3. Supporting rewrite-db for SBR events --------------------------------------- Limited to emiting USE <db_to> instead of USE <db_from>. USE statements can be emited by mysqlbinlog as a result of processing the following events (see process_event() function): - Query_log_event - Execute_load_query_log_event - Create_file_log_event TODO. Needed to check this list requires carefully !!! Conditions for emiting use-statement: - LOG_EVENT_SUPPRESS_USE_F is OFF for the event (e.g. it is ON for 'create database' statement) - event's db name differs from db_name in PRINT_EVENT_INFO (PRINT_EVENT_INFO keeps db name of the last issued USE statement; initially, this db name is empty). 3.1. In mysqlbinlog.cc - Add the following function: void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) { if (event->flags & LOG_EVENT_SUPPRESS_USE_F) return; /* - For events listed above get db_from = event->db; - If db_from is the same as pinfo->db then return; - If there is rewrite-db rule db_from->db_to, set db = db_to. Else set db = db_from; - Print "use <db>" to mysqlbinlog output - Set pinfo->db = db_from (this suppresses emiting use-statements by corresponding log_event's print-function) */ } - In process_event() function add print_use_stmt() invocations where needed (according to the events lis above), e.g.: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { case QUERY_EVENT: if (shall_skip_database(((Query_log_event*)ev)->db)) goto end; if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) { // Possibly in case of rewite-db rule for ev->db // a warning should be emited here (see note below) ... write_event_header_and_base64(ev, ...) ... } else { print_use_stmt((Query_log_event*)ev, print_event_info); ev->print(result_file, print_event_info); } break; ... } ... } Note. write_event_header_and_base64() does not print use-statement. It produces BINLOG statement using ev->temp_buf content (i.e. the binary log representation of the event). We don't rewrite temp_buf here with db_to name (as we do it for Table map event) - this implies the limitation 3 mentioned above. Question: Is supporting of rewite_db + --base64-output really needed currently? 4. Current status ----------------- The outlined design (implemented for mysql-5.1.37) is tested for simple test-cases. TODO. 1. Check list of events which can emit use-statement. 2. Supporting of rewite_db + --base64-output ?

If one is using statement-based replication, he can achieve this by grepping out "USE dbname" statements out of the output of mysqlbinlog(*). With row-based replication this is no longer possible, as database name is encoded within the the BINLOG '....' statement. This task is about adding an option to mysqlbinlog that would allow to change the names of used databases in both RBR and SBR events. (*) this implies that all statements refer to tables in the current database, doesn't catch updates made inside stored functions and so forth, but still works for a practially-important subset of cases. HIGH-LEVEL SPECIFICATION: Context ------- (See http://askmonty.org/wiki/index.php/Scratch/ReplicationOptions for global overview) At the moment, the server has a replication slave option --replicate-rewrite-db="from->to" the option affects - Table_map_log_event (all RBR events) - Load_log_event (LOAD DATA) - Query_log_event (SBR-based updates, with the usual assumption that the statement refers to tables in current database, so that changing the current database will make the statement to work on a table in a different database). See also MySQL BUG#42941. Note this bug is fixed in MySQL 5.1.37, which is not merged into MariaDB at the time of writing, but planned to be merged before release. What we could do ---------------- Option1: make mysqlbinlog accept --replicate-rewrite-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Make mysqlbinlog accept --replicate-rewrite-db options and process them to the same extent as replication slave would process --replicate-rewrite-db option. Option2: Add database-agnostic RBR events and --strip-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Right now RBR events require a databasename. It is not possible to have RBR event stream that won't mention which database the events are for. When I tried to use debugger and specify empty database name, attempt to apply the binlog resulted in this error: 090809 17:38:44 [ERROR] Slave SQL: Error 'Table '.tablename' doesn't exist' on opening tables, We could do as follows: - Make the server interpret empty database name in RBR event (i.e. in a Table_map_log_event) as "use current database". Binlog slave thread probably should not allow such events as it doesn't have a natural current database. - Add a mysqlbinlog --strip-db option that would = not produce any "USE dbname" statements = change databasename for all RBR events to be empty That way, mysqlbinlog output will be database-agnostic and apply to the current database. (this will have the usual limitations that we assume that all statements in the binlog refer to the current database). Option3: Enhance database rewrite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If there is a need to support database change for statements that use dbname.tablename notation and are replicated as statements (i.e. are DDL statements and/or DML statements that are binlogged as statements), then that could be supported as follows: - Make the server's parser recognize special form of comments /* !database-alias(oldname,newname) */ and save the mapping somewhere - Put the hooks in table open and name resolution code to use the saved mapping. Once we've done the above, it will be easy to perform a complete, no-compromise or restrictions database name change in binary log. It will be possible to do the rewrites either on the slave ( --replicate-rewrite-db will work for all kinds of statements), or in mysqlbinlog (adding a comment is easy and doesn't require mysqlbinlog to parse the statement). LOW-LEVEL DESIGN: Content ------- 1. Adding rewrite-db option 2. Supporting rewrite-db option for RBR events 3. Supporting rewrite-db option for SBR events (Limited to affecting only USE statements) 4. Current status 1. Adding rewrite-db option --------------------------- 1.1. Syntax: --rewrite-db='db_from->db_to' 1.2. Add 'OPT_REWRITE_DB' to 'options_client' (in client_priv.h). 1.3. In mysqlbinlog.cc: - Add { "rewrite-db", OPT_REWRITE_DB, ...} record to my_long_options: - Add Rpl_filter object to mysqlbinlog.cc Rpl_filter* binlog_filter; - Add corresponding switch case to get_one_option(): case OPT_REWRITE_DB: <extract db-from and db-to strings> binlog_filter->add_db_rewrite(db_from, db_to); break; . Note. To make Rpl_filter usable in a MYSQL_CLIENT context, few small additional changes are required: - In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) uses sql_alloc() which is THD dependent. These are to be modified as follows: #ifdef MYSQL_CLIENT extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc #endif class Sql_alloc { ... static void *operator new(size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } static void *operator new[](size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } ... } - In rpl_filter.cc: Rpl_filter::Rpl_filter() : ... { #ifdef MYSQL_CLIENT init_alloc_root(&sql_list_client_mem_root, ...); #endif ... } Rpl_filter::~Rpl_filter() { ... #ifdef MYSQL_CLIENT free_root(&sql_list_client_mem_root, ...); #endif } 2. Supporting rewrite-db for RBR events --------------------------------------- In binlog, each row operation event is preceded by Table map event(s) which maps table id(s) to database and table names. So, it's enough to support rewriting database name in a Table map. 2.1. Add rewrite_db() member to Table_map_log_event: int Table_map_log_event::rewrite_db( const char* new_db, size_t new_db_len, const Format_description_log_event* desc) { /* 1. In temp_buf member (possibly reallocating it) rewrite event length, db length, and db parts 2. Change m_dblen and m_dbnam members */ } Comment. This function assumes that temp_buf member contains Table map binlog representaion (temp_buf is used for creating corresponding BINLOG statement). 2.2. In mysqlbinlog modify corresponding switch case in the process_event() function: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { ... case TABLE_MAP_EVENT: { Table_map_log_event *map= ((Table_map_log_event *)ev); if (shall_skip_database(map->get_db_name())) { ... } // WL36 size_t new_len= 0; const char* new_db= binlog_filter->get_rewrite_db( map->get_db_name(), &new_len); if (new_len && map->rewrite_db(new_db, new_len, glob_description_event)) { error("Could not rewrite database name"); goto err; } } case WRITE_ROWS_EVENT: case DELETE_ROWS_EVENT: case UPDATE_ROWS_EVENT: ... } ... } Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains a (db_from, db_to) pair, this function returns pointer to db_to and sets len = db_to length; otherwise, it returns db_from and does not change len value. 3. Supporting rewrite-db for SBR events --------------------------------------- USE statements can be emited by mysqlbinlog as a result of processing the following events (see process_event() function): - Query_log_event - Execute_load_query_log_event - Create_file_log_event TODO. Needed to check this list requires carefully !!! Conditions for emiting use-statement: - LOG_EVENT_SUPPRESS_USE_F is OFF for the event (e.g. it is ON for 'create database' statement) - event's db name differs from db_name in PRINT_EVENT_INFO (PRINT_EVENT_INFO keeps db name of the last issued USE statement; initially, this db name is empty). 3.1. In mysqlbinlog.cc - Add the following function: void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) { if (event->flags & LOG_EVENT_SUPPRESS_USE_F) return; /* - For events listed above get db_from = event->db; - If db_from is the same as pinfo->db then return; - If there is rewrite-db rule db_from->db_to, set db = db_to. Else set db = db_from; - Print "use <db>" to mysqlbinlog output - Set pinfo->db = db_from (this suppresses emiting use-statements by corresponding log_event's print-function) */ } - In process_event() function add print_use_stmt() invocations where needed (according to the events lis above), e.g.: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { case QUERY_EVENT: if (shall_skip_database(((Query_log_event*)ev)->db)) goto end; if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) { // Possibly in case of rewite-db rule for ev->db // a warning should be emited here (see note below) ... write_event_header_and_base64(ev, ...) ... } else { print_use_stmt((Query_log_event*)ev, print_event_info); ev->print(result_file, print_event_info); } break; ... } ... } Note. write_event_header_and_base64() does not print use-statement. It produces BINLOG statement using ev->temp_buf content (i.e. the binary log representation of the event). We don't rewrite temp_buf here with db_to name (as we do it for Table map event) - this implies the limitation 3 mentioned above. Question: Is supporting of rewite_db + --base64-output really needed currently? 4. Current status ----------------- The outlined design (implemented for mysql-5.1.37) is tested for simple test-cases. TODO. 1. Check list of events which can emit use-statement. 2. Supporting of rewite_db + --base64-output ?

If one is using statement-based replication, he can achieve this by grepping out "USE dbname" statements out of the output of mysqlbinlog(*). With row-based replication this is no longer possible, as database name is encoded within the the BINLOG '....' statement. This task is about adding an option to mysqlbinlog that would allow to change the names of used databases in both RBR and SBR events. (*) this implies that all statements refer to tables in the current database, doesn't catch updates made inside stored functions and so forth, but still works for a practially-important subset of cases. HIGH-LEVEL SPECIFICATION: Context ------- (See http://askmonty.org/wiki/index.php/Scratch/ReplicationOptions for global overview) At the moment, the server has a replication slave option --replicate-rewrite-db="from->to" the option affects - Table_map_log_event (all RBR events) - Load_log_event (LOAD DATA) - Query_log_event (SBR-based updates, with the usual assumption that the statement refers to tables in current database, so that changing the current database will make the statement to work on a table in a different database). See also MySQL BUG#42941. Note this bug is fixed in MySQL 5.1.37, which is not merged into MariaDB at the time of writing, but planned to be merged before release. What we could do ---------------- Option1: make mysqlbinlog accept --replicate-rewrite-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Make mysqlbinlog accept --replicate-rewrite-db options and process them to the same extent as replication slave would process --replicate-rewrite-db option. Option2: Add database-agnostic RBR events and --strip-db option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Right now RBR events require a databasename. It is not possible to have RBR event stream that won't mention which database the events are for. When I tried to use debugger and specify empty database name, attempt to apply the binlog resulted in this error: 090809 17:38:44 [ERROR] Slave SQL: Error 'Table '.tablename' doesn't exist' on opening tables, We could do as follows: - Make the server interpret empty database name in RBR event (i.e. in a Table_map_log_event) as "use current database". Binlog slave thread probably should not allow such events as it doesn't have a natural current database. - Add a mysqlbinlog --strip-db option that would = not produce any "USE dbname" statements = change databasename for all RBR events to be empty That way, mysqlbinlog output will be database-agnostic and apply to the current database. (this will have the usual limitations that we assume that all statements in the binlog refer to the current database). Option3: Enhance database rewrite ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If there is a need to support database change for statements that use dbname.tablename notation and are replicated as statements (i.e. are DDL statements and/or DML statements that are binlogged as statements), then that could be supported as follows: - Make the server's parser recognize special form of comments /* !database-alias(oldname,newname) */ and save the mapping somewhere - Put the hooks in table open and name resolution code to use the saved mapping. Once we've done the above, it will be easy to perform a complete, no-compromise or restrictions database name change in binary log. It will be possible to do the rewrites either on the slave ( --replicate-rewrite-db will work for all kinds of statements), or in mysqlbinlog (adding a comment is easy and doesn't require mysqlbinlog to parse the statement). LOW-LEVEL DESIGN: Content ------- 1. Adding rewrite-db option 2. Supporting rewrite-db option for RBR events 3. Supporting rewrite-db option for SBR events (Limited to affecting only USE statements) 4. Current status 1. Adding rewrite-db option --------------------------- 1.1. Syntax: --rewrite-db='db_from->db_to' 1.2. Add 'OPT_REWRITE_DB' to 'options_client' (in client_priv.h). 1.3. In mysqlbinlog.cc: - Add { "rewrite-db", OPT_REWRITE_DB, ...} record to my_long_options: - Add Rpl_filter object to mysqlbinlog.cc Rpl_filter* binlog_filter; - Add corresponding switch case to get_one_option(): case OPT_REWRITE_DB: <extract db-from and db-to strings> binlog_filter->add_db_rewrite(db_from, db_to); break; . Note. To make Rpl_filter usable in a MYSQL_CLIENT context, few small additional changes are required: - In sql_list.cc/h, Sql_alloc::new(size_t) and Sql_alloc::new[](size_t) uses sql_alloc() which is THD dependent. These are to be modified as follows: #ifdef MYSQL_CLIENT extern MEM_ROOT sql_list_client_mem_root; // defined in sql_list.cc #endif class Sql_alloc { ... static void *operator new(size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } static void *operator new[](size_t size) throw () { #ifndef MYSQL_CLIENT return sql_alloc(size); #else return alloc_root(&sql_list_client_mem_root, size); #endif } ... } - In rpl_filter.cc: Rpl_filter::Rpl_filter() : ... { #ifdef MYSQL_CLIENT init_alloc_root(&sql_list_client_mem_root, ...); #endif ... } Rpl_filter::~Rpl_filter() { ... #ifdef MYSQL_CLIENT free_root(&sql_list_client_mem_root, ...); #endif } 2. Supporting rewrite-db for RBR events --------------------------------------- In binlog, each row operation event is preceded by Table map event(s) which maps table id(s) to database and table names. So, it's enough to support rewriting database name in a Table map. 2.1. Add rewrite_db() member to Table_map_log_event: int Table_map_log_event::rewrite_db( const char* new_db, size_t new_db_len, const Format_description_log_event* desc) { /* 1. In temp_buf member (possibly reallocating it) rewrite event length, db length, and db parts 2. Change m_dblen and m_dbnam members */ } Comment. This function assumes that temp_buf member contains Table map binlog representaion (temp_buf is used for creating corresponding BINLOG statement). 2.2. In mysqlbinlog modify corresponding switch case in the process_event() function: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { ... case TABLE_MAP_EVENT: { Table_map_log_event *map= ((Table_map_log_event *)ev); if (shall_skip_database(map->get_db_name())) { ... } // WL36 size_t new_len= 0; const char* new_db= binlog_filter->get_rewrite_db( map->get_db_name(), &new_len); if (new_len && map->rewrite_db(new_db, new_len, glob_description_event)) { error("Could not rewrite database name"); goto err; } } case WRITE_ROWS_EVENT: case DELETE_ROWS_EVENT: case UPDATE_ROWS_EVENT: ... } ... } Comment. Rpl_filter::get_rewrite_db(db_from, &len): if filter contains a (db_from, db_to) pair, this function returns pointer to db_to and sets len = db_to length; otherwise, it returns db_from and does not change len value. 3. Supporting rewrite-db for SBR events --------------------------------------- USE statements can be emited by mysqlbinlog as a result of processing the following events (see process_event() function): - Query_log_event - Execute_load_query_log_event - Create_file_log_event TODO. Needed to check this list requires carefully !!! Conditions for emiting use-statement: - LOG_EVENT_SUPPRESS_USE_F is OFF for the event (e.g. it is ON for 'create database' statement) - event's db name differs from db_name in PRINT_EVENT_INFO (PRINT_EVENT_INFO keeps db name of the last issued USE statement; initially, this db name is empty). 3.1. In mysqlbinlog.cc - Add the following function: void print_use_stmt(Log_event* event, PRINT_EVENT_INFO* pinfo) { if (event->flags & LOG_EVENT_SUPPRESS_USE_F) return; /* - For events listed above get db_from = event->db; - If db_from is the same as pinfo->db then return; - If there is rewrite-db rule db_from->db_to, set db = db_to. Else set db = db_from; - Print "use <db>" to mysqlbinlog output - Set pinfo->db = db_from (this suppresses emiting use-statements by corresponding log_event's print-function) */ } - In process_event() function add print_use_stmt() invocations where needed (according to the events lis above), e.g.: Exit_status process_event( PRINT_EVENT_INFO *print_event_info, Log_event *ev, ...) { ... switch (ev_type) { case QUERY_EVENT: if (shall_skip_database(((Query_log_event*)ev)->db)) goto end; if (opt_base64_output_mode == BASE64_OUTPUT_ALWAYS) { // Possibly in case of rewite-db rule for ev->db // a warning should be emited here (see note below) ... write_event_header_and_base64(ev, ...) ... } else { print_use_stmt((Query_log_event*)ev, print_event_info); ev->print(result_file, print_event_info); } break; ... } ... } Note. write_event_header_and_base64() does not print use-statement. It produces BINLOG statement using ev->temp_buf content (i.e. the binary log representation of the event). We don't rewrite temp_buf here with db_to name (as we do it for Table map event) - this implies the limitation 3 mentioned above. Question: Is supporting of rewite_db + --base64-output really needed currently? 4. Current status ----------------- The outlined design (implemented for mysql-5.1.37) is tested for simple test-cases. TODO. 1. Check list of events which can emit use-statement. 2. Supporting of rewite_db + --base64-output ? ESTIMATED WORK TIME ESTIMATED COMPLETION DATE ----------------------------------------------------------------------- WorkLog (v3.5.9)

A --engine=<storage_engine>:<option> was not always properly parsed and in some cases crashed. Fixed by eliminating "set storage_engine = ..." and adding proper DDL generation. Initialized an unitialized buffer to prevent crashes and fixed to use proper pointer for in case of --engine=<storage_engine>:<option> being the last element in list of --engines. Also cleaned up code for better readability. Q: Should MySQL's replication actually replicate a "set storage_engine = ..." command or not? A: No it should not. It is documented here: http://dev.mysql.com/doc/refman/5.1/en/replication-features-variables.html ... "The storage_engine system variable is not replicated, which is a good thing for replication between different storage engines." ...

[Maria-developers] Log_of_MariaDB_Contributions
by Henrik Ingo 14 Sep '09

14 Sep '09

Hi all Maria Developers I promised to do this some weeks ago: http://askmonty.org/wiki/index.php/Log_of_MariaDB_Contributions We need to include in our routines that any time a Maria Captain pushes something to the main trunk that was not 100% developed by Monty Program employees (and hopefully this will happen often :-), a log entry to that page is inserted. This is important so that we have a documented trail on how rights have been assigned for all code going into the trunk. The Linux kernel seems to have incorporated this into their git processes by adding signed-off headers to their git changeset metadata (noting that Linux of course is GPL only). If there is a way to do something similar with bzr I'm open to suggestions. If we did it with bzr, my next question would be, how can a stupid manager like me easily get a report of the signed-off trail? Similarly, feel free to modify the above wiki page if some other format works better. (For instance, we may agree with some contributor that anything available in a dedicated lp tree is contributed to MariaDB.) Sanja: it seems that the first thing that should be added to the page is the virtual columns patch you are working on. Having come from Drizzle there is a chance it is under BSD? henrik -- email: henrik.ingo(a)avoinelama.fi tel: +358-40-5697354 www: www.avoinelama.fi/~hingo book: www.openlife.cc

[Maria-developers] Inventory of 3rd party GPL code in MariaDB (other than Sun)
by Henrik Ingo 13 Sep '09

13 Sep '09

Hi Related to the work I'm doing with the EU, it seems wise to conduct a review of what 3rd party code is used in MySQL/MariaDB and under what license. In other words I need to know: Things in MySQL not owned by Sun. I so far come to think of 2 modules: Readline library used in MySQL client.

#At lp:maria 2728 knielsen(a)knielsen-hq.org 2009-09-11 After-merge fix for MySQL 5.1.38 merge into MariaDB. Due to a bugfix for enum options in MariaDB, my_getopt parses enums into an ulong. However, some new code from MySQL was written to assume enums take an uint. Fix by using the correct type. (The new MySQL code in addition had an implicit assumption that my_bool and uint were compatible; remove this assumption). modified: mysys/my_getopt.c sql/sql_plugin.cc === modified file 'mysys/my_getopt.c' --- a/mysys/my_getopt.c 2009-09-07 20:50:10 +0000 +++ b/mysys/my_getopt.c 2009-09-11 13:20:03 +0000 @@ -414,11 +414,17 @@ invalid value '%s'", (optp->var_type & GET_TYPE_MASK) == GET_ENUM)) { if (optend == disabled_my_option) - *((my_bool*) value)= (my_bool) 0; + if ((optp->var_type & GET_TYPE_MASK) == GET_BOOL) + *((my_bool*) value)= (my_bool) 0; + else + *((ulong*) value)= (ulong) 0; else { if (!optend) /* No argument -> enable option */ - *((my_bool*) value)= (my_bool) 1; + if ((optp->var_type & GET_TYPE_MASK) == GET_BOOL) + *((my_bool*) value)= (my_bool) 1; + else + *((ulong*) value)= (ulong) 1; else argument= optend; } === modified file 'sql/sql_plugin.cc' --- a/sql/sql_plugin.cc 2009-09-07 20:50:10 +0000 +++ b/sql/sql_plugin.cc 2009-09-11 13:20:03 +0000 @@ -2980,12 +2980,12 @@ static int construct_options(MEM_ROOT *m Allocate temporary space for the value of the tristate.

DESCRIPTION: According to complaints in BUG#46640: 1. mysqlbinlog will emit a 5.0-incompatible "format description binlog statement" even when reading a binary log that was produced by 5.0. This will cause an error when one tires to apply mysqlbinlog output to a 5.0.x server. 2.

This can cause problems like infinite recursive application in a circular replication topology. This WL is to fix these issues. HIGH-LEVEL SPECIFICATION: First item ---------- AFAIU what needs to be done is: 1. record a source server version (it is in the first binlog event). 2. don't emit a BINLOG statement if the recorded version number is 5.0.x or below. and we'll get a 5.0-applicable binlog. Second item ----------- One question that one needs to sort out before disabling server_id change is why it was put there in the first place? Should it be always removed? First, the problem is not the format description log event. In fact all log events have their own value of server_id, and every event in the BINLOG statement is executed with its own id as server_id. It seems it was introduced deliberately in the patch for Bug#32407. This patch makes sql thread and BINLOG statement share code path for executing the binary event, even though the bug is really about something different (outputting format description event to allow proper execution of other BINLOG statements). Nevertheless, I think using the server_id in the events of a BINLOG statement is wrong: 1. It is different behaviour from executing normal statement-based events not written using BINLOG. 2. It causes the possibility for infinite cycle of replication in a cyclic replication setup, if the server ids in BINLOG are different from all other server ids in the cycle. 3. The functionality of applying events with original server id from the event is still available by pointing the slave thread to the binlog. The functionality of applying row-based binlog events with server id of the server executing the BINLOG statements is not otherwise available. In fact most of the code from the slave thread that is now also run when executing BINLOG statements is redundant, or does the wrong thing (like updating binlog position). Maybe there is a confusion on the purpose of the BINLOG statement. Is it to be able to apply row-based events manually to a server (mysqlbinlog|mysql)? Or is it to be able to simulate the effect of the slave sql thread? I think the former is the most important one. LOW-LEVEL DESIGN: I think the fix for point 2 is to replace the call to apply_event_and_update_pos() in mysql_client_binlog_statement() with a direct call to ev->apply_event(). However, I need to check two things to be sure this is correct: 1. The existing code does if (!ev->when) ev->when= my_time(0) Need to understand if this is needed/correct or not. 2. The existing code does ev->update_pos(). I think this is redundant for BINLOG statement (as it uses a fake rli structure), but I need to check to make sure. Once this is done, point 1 may no longer be needed. The user can use --base64-output=never when applying the output to a 5.0 server, and omit that option when applying the output to a 5.1 server. There should be no need to omit the format description event in the output when other BINLOG statements for row events are present, as it no longer changes the server id. In fact the format description event is required to be able to execute other BINLOG statements, as its purpose is to define the binary format of the events contained in these statements. Alternatively, we could implement that if the format description event of the source binlog has server version < 5.1, and --base64-output=auto (default), then the format description event is omitted (and should any BINLOG statement be needed, unlikely as it is from a 5.0 server, we will need to throw an error). The binlog format version for 5.0 and 5.1 is actually the same, hence the need to look at server version to guess if the format description event can be omitted.

This can cause problems like infinite recursive application in a circular replication topology. This WL is to fix these issues. HIGH-LEVEL SPECIFICATION: First item ---------- AFAIU what needs to be done is: 1. record a source server version (it is in the first binlog event). 2. don't emit a BINLOG statement if the recorded version number is 5.0.x or below. and we'll get a 5.0-applicable binlog. Second item ----------- One question that one needs to sort out before disabling server_id change is why it was put there in the first place? Should it be always removed? First, the problem is not the format description log event. In fact all log events have their own value of server_id, and every event in the BINLOG statement is executed with its own id as server_id. It seems it was introduced deliberately in the patch for Bug#32407. This patch makes sql thread and BINLOG statement share code path for executing the binary event, even though the bug is really about something different (outputting format description event to allow proper execution of other BINLOG statements). Nevertheless, I think using the server_id in the events of a BINLOG statement is wrong: 1. It is different behaviour from executing normal statement-based events not written using BINLOG. 2. It causes the possibility for infinite cycle of replication in a cyclic replication setup, if the server ids in BINLOG are different from all other server ids in the cycle. 3. The functionality of applying events with original server id from the event is still available by pointing the slave thread to the binlog. The functionality of applying row-based binlog events with server id of the server executing the BINLOG statements is not otherwise available. In fact most of the code from the slave thread that is now also run when executing BINLOG statements is redundant, or does the wrong thing (like updating binlog position). Maybe there is a confusion on the purpose of the BINLOG statement. Is it to be able to apply row-based events manually to a server (mysqlbinlog|mysql)? Or is it to be able to simulate the effect of the slave sql thread? I think the former is the most important one. LOW-LEVEL DESIGN: I think the fix for point 2 is to replace the call to apply_event_and_update_pos() in mysql_client_binlog_statement() with a direct call to ev->apply_event(). However, I need to check two things to be sure this is correct: 1. The existing code does if (!ev->when) ev->when= my_time(0) Need to understand if this is needed/correct or not. 2. The existing code does ev->update_pos(). I think this is redundant for BINLOG statement (as it uses a fake rli structure), but I need to check to make sure. Once this is done, point 1 may no longer be needed. The user can use --base64-output=never when applying the output to a 5.0 server, and omit that option when applying the output to a 5.1 server. There should be no need to omit the format description event in the output when other BINLOG statements for row events are present, as it no longer changes the server id. In fact the format description event is required to be able to execute other BINLOG statements, as its purpose is to define the binary format of the events contained in these statements. Alternatively, we could implement that if the format description event of the source binlog has server version < 5.1, and --base64-output=auto (default), then the format description event is omitted (and should any BINLOG statement be needed, unlikely as it is from a 5.0 server, we will need to throw an error). The binlog format version for 5.0 and 5.1 is actually the same, hence the need to look at server version to guess if the format description event can be omitted.

#At lp:maria 2731 knielsen(a)knielsen-hq.org 2009-09-09 Bug#46640: output from mysqlbinlog command in 5.1 breaks replication The BINLOG statement was sharing too much code with the slave SQL thread, introduced with the patch for Bug#32407. This caused statements to be logged with the wrong server_id, the id stored inside the events of the BINLOG statement rather than the id of the running server. Fix by rearranging code a bit so that only relevant parts of the code are executed by the BINLOG statement. modified: mysql-test/extra/binlog_tests/binlog.test mysql-test/suite/binlog/r/binlog_row_binlog.result mysql-test/suite/binlog/r/binlog_stm_binlog.result sql/log_event.cc sql/slave.cc sql/slave.h sql/sql_binlog.cc per-file messages: mysql-test/extra/binlog_tests/binlog.test Add test case. mysql-test/suite/binlog/r/binlog_row_binlog.result Add test case. mysql-test/suite/binlog/r/binlog_stm_binlog.result Add test case. sql/log_event.cc Move rows_event_stmt_clean() call from update_pos() to apply_event(). This in any case makes more sense, and is needed as update_pos() is no longer called when executing BINLOG statements. sql/slave.cc The skip flag is no longer needed, as the code path for BINLOG statement has been cleaned up. sql/slave.h The skip flag is no longer needed, as the code path for BINLOG statement has been cleaned up. sql/sql_binlog.cc Don't invoke the update_pos() code path for the BINLOG statement, as it contains code that is redundant and/or harmful (especially setting thd->server_id). === modified file 'mysql-test/extra/binlog_tests/binlog.test' --- a/mysql-test/extra/binlog_tests/binlog.test 2009-03-25 19:41:16 +0000 +++ b/mysql-test/extra/binlog_tests/binlog.test 2009-09-09 15:27:23 +0000 @@ -258,3 +258,39 @@ dec $it; } show master status /* must show new binlog index after rotating */; drop table t3; + + +# +# Bug#46640: output from mysqlbinlog command in 5.1 breaks replication +# + +connect (fresh,localhost,root,,test); +connection fresh; + +RESET MASTER; +CREATE TABLE t1 (a INT PRIMARY KEY); + +# Format description event, with server_id = 10; +BINLOG ' +3u9kSA8KAAAAZgAAAGoAAAABAAQANS4xLjM1LW1hcmlhLWJldGExLWRlYnVnLWxvZwAAAAAAAAAA +AAAAAAAAAAAAAAAAAADe72RIEzgNAAgAEgAEBAQEEgAAUwAEGggAAAAICAgC +'; + +# What server_id is logged for a statement?

This will cause an error when one tires to apply mysqlbinlog output to a 5.0.x server. 2. When one executes a BINLOG statement (containing "format description binlog statement" or other events), this will cause subsequent statements run in the same session to be binlogged with the server id of the last event executed, not with the real server id. This can cause problems like infinite recursive application in a circular replication topology. This WL is to fix these issues. HIGH-LEVEL SPECIFICATION: First item ---------- AFAIU what needs to be done is: 1. record a source server version (it is in the first binlog event). 2. don't emit a BINLOG statement if the recorded version number is 5.0.x or below. and we'll get a 5.0-applicable binlog. Second item ----------- One question that one needs to sort out before disabling server_id change is why it was put there in the first place? Should it be always removed? First, the problem is not the format description log event. In fact all log events have their own value of server_id, and every event in the BINLOG statement is executed with its own id as server_id. It seems it was introduced deliberately in the patch for Bug#32407. This patch makes sql thread and BINLOG statement share code path for executing the binary event, even though the bug is really about something different (outputting format description event to allow proper execution of other BINLOG statements). Nevertheless, I think using the server_id in the events of a BINLOG statement is wrong: 1. It is different behaviour from executing normal statement-based events not written using BINLOG. 2. It causes the possibility for infinite cycle of replication in a cyclic replication setup, if the server ids in BINLOG are different from all other server ids in the cycle. 3. The functionality of applying events with original server id from the event is still available by pointing the slave thread to the binlog. The functionality of applying row-based binlog events with server id of the server executing the BINLOG statements is not otherwise available. In fact most of the code from the slave thread that is now also run when executing BINLOG statements is redundant, or does the wrong thing (like updating binlog position). Maybe there is a confusion on the purpose of the BINLOG statement. Is it to be able to apply row-based events manually to a server (mysqlbinlog|mysql)? Or is it to be able to simulate the effect of the slave sql thread? I think the former is the most important one. LOW-LEVEL DESIGN: I think the fix for point 2 is to replace the call to apply_event_and_update_pos() in mysql_client_binlog_statement() with a direct call to ev->apply_event(). However, I need to check two things to be sure this is correct: 1. The existing code does if (!ev->when) ev->when= my_time(0) Need to understand if this is needed/correct or not. 2. The existing code does ev->update_pos(). I think this is redundant for BINLOG statement (as it uses a fake rli structure), but I need to check to make sure. Once this is done, point 1 may no longer be needed. The user can use --base64-output=never when applying the output to a 5.0 server, and omit that option when applying the output to a 5.1 server. There should be no need to omit the format description event in the output when other BINLOG statements for row events are present, as it no longer changes the server id. In fact the format description event is required to be able to execute other BINLOG statements, as its purpose is to define the binary format of the events contained in these statements. Alternatively, we could implement that if the format description event of the source binlog has server version < 5.1, and --base64-output=auto (default), then the format description event is omitted (and should any BINLOG statement be needed, unlikely as it is from a 5.0 server, we will need to throw an error). The binlog format version for 5.0 and 5.1 is actually the same, hence the need to look at server version to guess if the format description event can be omitted.

Hakan Kuecuekyilmaz <hakan(a)askmonty.org> writes: > Where do you need some help for our release? Looking at http://askmonty.org/wiki/index.php/MariaDB_5.1_TODO, seems it is currently mostly the mysql-5.1.38 merge. One thing that would be useful is to try some additional testing on top of what is already in Buildbot, as there is quite a lot missing... some of this might be better done after the merge is pushed though, but you could start preparing. Maybe you could check what additional test suites/tools are already available that could be used? Stuff like unit tests, mysql-test-run --ps-protocol, additional test suites... One thing in particular is to prepare to test the actual release. Releases are built in a two-step process, first build a source tarball, and then build the binaries from those sources. Buildbot builds directly from a bzr checkout. And Binaries are run from the installed location, while Buildbot runs the tests from the build directory. It would be really embarrassing if some major part of our binaries were released completely broken due to some file or something not being included and no testing at all done :-(. So we could use some tools to test stuff like this. Eventually we want this in Buildbot of course. Concrete suggestion: 1. Testing on installed mysqld. Run `BUILD/compile-dist && make dist`. Unpack those sources and run `./configure <options> && make && make install`. Run `make clean` (to catch bad references into build dir). Then run the testsuite on the installed mysqld. 2. What we used to call "smoke test" at MySQL: Build a binary package, then install it on some machine and see that it can start and stop. Basically testing the package stuff (directory structure, mysqld_safe, ...) which is not covered by the test suite. See http://askmonty.org/wiki/index.php/MariaDB::PackageBuild for how packages are built currently. > My idea to work on and look into it: Currently we have around 10 test > failures on Mac/PPC. If you want, I can start looking into those > failures. Where should we report failing tests? I would like to open > a bug for each test failure. Currently we seem to be using Launchpad for bugs. However, it does not sound all that useful to blindly report one bug per failure. Probably some of them are related with same root cause. If you can identify those root causes, then one bug each makes sense (maybe this is what you meant). Otherwise a single bug probably, just noting that someone needs to look into it when time is available. - Kristian.

Isn't this dead code? Just above, the code does this: if (!query) { is_command= TRUE; query= command_name[thd->command].str; query_length= command_name[thd->command].length; } So the above part of the patch will only run when query!=0 && query_length==0. Can this ever happen? If not, the code should probably be removed. If so, maybe add a comment explaining when this happens (and change it to be in an else {} clause of the if statement just before it). - Kristian.

[Maria-developers] No more compiler warnings in lp:maria!
by Kristian Nielsen 07 Sep '09

07 Sep '09

While the subject of this mail is not quite true yet, I'm happy to announce progress on this project that Monty and I have been discussing for some time. Basically, compiler warnings are very useful to catch a number of bugs in our sources. This has been proven time and time again. However, to do this effectively, we need to keep a state where there are no compiler warnings in the main tree, so that we can detect any new warnings introduced by patches and fix any problems accordingly. With my latest push this morning, the Buildbot compiles on builders hardy-amd64-valgrind and work-amd64-valgrind are now completely free of warnings. This means any new patches must be also clean from warnings on these hosts. Any newly introduced warnings should be fixed ASAP. There are still some compiler warnings left on the other hosts, which would be really good to also eliminate. Any help in this direction would be greatly appreciated. There are a few compiler warnings that could not be fixed meaningfully in the source for various reasons. These warnings are instead suppressed from Buildbot using the file support-files/compiler_warnings.supp. Over time we should strive to remove things from this file. However, we should not make stupid changes to the code just to make a silly compiler happy. I also added to the tree this script: support-files/ccfilter This can be used locally by developers to apply support-files/compiler_warnings.supp to the output of a local build, just like Buildbot suppresses compiler warnings from this file. This is useful to check that new patches are warning-free before pushing. There are some comments at the start of the script describing usage. But basically, run ./configure with CC="ccfilter gcc" CXX="ccfilter gcc" Then the suppressed compiler warnings will be removed from the compiler output. And setting the FAILONWARNING environment variable can be used to cause a build failure on non-suppressed warning (similar to -Wall, but heeding support-files/compiler_warnings.supp). - Kristian.

[Maria-developers] Documentation for new features in MariaDB
by Kristian Nielsen 07 Sep '09

07 Sep '09

We are starting to add new features to MariaDB (that are not in MySQL), including user-visible features. I think we need to decide now how we will handle keeping documentation for these new features. There is an open issue about the MySQL documentation being non-free, and whether we can do anything about it. But until this is resolved, on way or the other, we still need somewhere to write documentation. I think it is mainly about setting up a repository somewhere and start adding text. The important thing now is to get the content there, the presentation can be enhanced later. So we would have a manual "differences between MariaDB and MySQL" or something. If we have the content we can use it later in whatever form we need, if we omit adding the content now it is going to be really hard to figure out everything that's missing in a year or two. Daniel, any suggestions for what format to use? Can we use the same format as the MySQL documentation (is it docbook or something, can't remember)? Also, until we get procedures like at MySQL/Sun for a documentation team that ensures all features and bug fixes get documented, I think it is the responsibility of each developer that documentation gets added in the right place. I would really like to see us keeping the up the standard that everything in MySQL (now MariaDB) is documented. - Kristian.

We discussed this again in MariaDB, and would like to get things working better for now. What Monty suggested was that it would work for Sun if we submit specific patches under a BSD-new license. I realise that the http://tinyurl.com/q2ulgt patch request is now so old that it may be of no interest to you any longer. But if you have a request for this or other patches, please send them. All developers at Monty Program have the ability to submit their work to Sun at their own discretion, so we should be able to make this work on a low-overhead technician-to-technician level. - Kristian.

[Maria-developers] Issues with static linking
by Kristian Nielsen 02 Sep '09

02 Sep '09

The issue of static vs. dynamic linking keeps coming up in relation to building of MariaDB (and MySQL). I thought I would share some thoughts on this. There is a tradition for linking statically in MySQL for performance and other reasons. However, these days there are a number of problems with static linking, to the extent that I think static linking of system libraries is really impractical. Now, in a *fully* static binary that does not load any shared libraries at run-time, static linking works ok. However, in most real-life situations, there is always some amount of dynamic linking: - Nowadays glibc uses dynamic loading at runtime to handle NSS. And while this can be disabled, it is strongly discouraged: http://gnu.gds.tuwien.ac.at/software/libc/FAQ.html#s-2.22 - Support for dynamic loading of pluggable storage engines requires dynamic loading at runtime. - Even just installing a single UDF (user-defined function) into the server requires dynamic loading of a shared library. - Client libraries (libmysql, libmysqld) may be used in dynamic shared objects built by users (like the Amarok plugin using libmysqld). So a binary built for general distribution really has no choice but to support some dynamic linking (users building on their own can do differently, of course). The problem now is the following: Consider a binary B that loads a dynamic shared object S. Assume that both B and S use the same library L. Now if B links L statically, part of L, but not necessarily all of it, will be included inside B. These parts of L will be of some version v1 of L determined when B was built, and they will be visible to S. But S may use other parts of L not included in B, and these may be of a different version v2 of L, as determined by how S was linked and loaded. The result is that S will be using a mix of two different versions of L. This very rarely work. Typically, L will be eg. libc, and B will contain parts of libc from the build machine, while S will use the libc installed on the machine on which B is run. This is the basic problem. Because of the way linking works in Linux and similar systems, libraries used by dynamically loaded objects must themselves be linked dynamically to avoid this problem with mixed versions. This applies to things like libc and libz. On the other hand objects that are internally part of MariaDB (libmystrings, libmyisam, etc.) are no problem to link statically. There are also a number of bugs on MySQL relating to this. So it is not just an academic problem. The conclusion as far as I can see is that for MariaDB binaries, we should link system libraries dynamically, or things will just not work correctly for our users. Unless someone knows a way to avoid these problems. ----------------------------------------------------------------------- Just to recap, the main benefits of static linking are, to my knowledge: 1. Performance. On i386, position-independent code (as needed in shared objects) needs code like this in the prologue of every function that accesses global names (like calling other functions): call label label: pop %ebx This consumes cycles, and reduces available registers on an already register-starved architecture. 2. System independence. Upgrading system libraries on the host does not affect the application, eg. less change of breakage due to incompatibility (though this can be also a disadvantage in case of eg. security fixes). As far as I know, nowadays, these advantages are much smaller: 1. On x86_64, the CPU architecture has been fixed to support position-independent code with little or no extra overhead (like pc-relative addressing modes). 2. Glibc has become much better at preserving binary compatibility across versions. ----------------------------------------------------------------------- Hope this helps, - Kristian.
