Detailed Description

A handler for a PERFORMANCE_SCHEMA table.

Definition at line 35 of file ha_perfschema.h.

Constructor & Destructor Documentation

ha_perfschema::ha_perfschema	(	handlerton *	hton,
		TABLE_SHARE *	share
	)

Create a new performance schema table handle on a table.

Parameters

hton	storage engine handler singleton
share	table share

Definition at line 197 of file ha_perfschema.cc.

Member Function Documentation

const char ** ha_perfschema::bas_ext ( void  ) const

virtual

If frm_error() is called then we will use this to find out what file extentions exist for the storage engine. This is also used by the default rename_table and delete_table method in handler.cc.

For engines that have two file name extentions (separate meta/index file and data file), the order of elements is relevant. First element of engine file name extentions array should be meta/index file extention. Second element - data file extention. This order is assumed by prepare_for_repair() when REPAIR TABLE ... USE_FRM is issued.

Implements handler.

Definition at line 208 of file ha_perfschema.cc.

int ha_perfschema::close ( void  )

virtual

Close a table handle.

See Also

open.

Implements handler.

Definition at line 228 of file ha_perfschema.cc.

int ha_perfschema::delete_all_rows ( void  )

virtual

This is called to delete all rows in a table If the handler don't support this, then this function will return HA_ERR_WRONG_COMMAND and MySQL will delete the rows one by one.

Reimplemented from handler.

Definition at line 370 of file ha_perfschema.cc.

Here is the caller graph for this function:

int ha_perfschema::delete_row

(

const uchar *

buf

)

Delete a row.

Parameters

buf	the row to delete

Returns

0 on success

Definition at line 275 of file ha_perfschema.cc.

Here is the call graph for this function:

int ha_perfschema::delete_table ( const char *  name )

virtual

Delete a table in the engine. Called for base as well as temporary tables.

Delete all files with extension from bas_ext().

Parameters

name	Base name of table

Note

We assume that the handler may return more extensions than was actually used for the file.

Return values

0	If we successfully deleted at least one file from base_ext and didn't get any other errors than ENOENT
!0	Error

Reimplemented from handler.

Definition at line 404 of file ha_perfschema.cc.

ha_rows ha_perfschema::estimate_rows_upper_bound ( void  )

inlinevirtual

Return upper bound of current number of records in the table (max. of how many records one will retrieve when doing a full table scan) If upper bound is not known, HA_POS_ERROR should be returned as a max possible upper bound.

Reimplemented from handler.

Definition at line 99 of file ha_perfschema.h.

ulong ha_perfschema::index_flags ( uint  , uint  , bool    ) const

inlinevirtual

Operations supported by indexes. None, there are no indexes.

Implements handler.

Definition at line 84 of file ha_perfschema.h.

int ha_perfschema::open ( const char *  name, int  mode, uint  test_if_locked  )

virtual

Open a performance schema table.

Parameters

name	the table to open
mode	unused
test_if_locked	unused

Returns

0 on success

Implements handler.

Definition at line 213 of file ha_perfschema.cc.

void ha_perfschema::position ( const uchar *  record )

virtual

Read the row current position.

Parameters

record

the current row

Implements handler.

Definition at line 336 of file ha_perfschema.cc.

Here is the call graph for this function:

void ha_perfschema::print_error ( int  error, myf  errflag  )

virtual

Print error that we got from handler function.

Note

In case of delete table it's only safe to use the following parts of the 'table' structure:

• table->s->path
• table->alias

Reimplemented from handler.

Definition at line 440 of file ha_perfschema.cc.

virtual my_bool ha_perfschema::register_query_cache_table ( THD *  thd, char *  table_key, uint  key_length, qc_engine_callback *  engine_callback, ulonglong *  engine_data  )

inlinevirtual

Register a named table with a call back function to the query cache.

Parameters

	thd	The thread handle
	table_key	A pointer to the table name in the table cache
	key_length	The length of the table name
[out]	engine_callback	The pointer to the storage engine call back function
[out]	engine_data	Storage engine specific data which could be anything

This method offers the storage engine, the possibility to store a reference to a table name which is going to be used with query cache. The method is called each time a statement is written to the cache and can be used to verify if a specific statement is cachable. It also offers the possibility to register a generic (but static) call back function which is called each time a statement is matched against the query cache.

Note

If engine_data supplied with this function is different from engine_data supplied with the callback function, and the callback returns FALSE, a table invalidation on the current table will occur.

Returns

Upon success the engine_callback will point to the storage engine call back function, if any, and engine_data will point to any storage engine data used in the specific implementation.

Return values

TRUE	Success
FALSE	The specified table or current statement should not be cached

Reimplemented from handler.

Definition at line 193 of file ha_perfschema.h.

int ha_perfschema::rename_table ( const char *  from, const char *  to  )

virtual

Default rename_table() and delete_table() rename/delete files with a given name and extensions from bas_ext().

These methods can be overridden, but their default implementation provide useful functionality.

Reimplemented from handler.

Definition at line 410 of file ha_perfschema.cc.

int ha_perfschema::rnd_end ( void  )

virtual

Scan end.

See Also

rnd_init.

Reimplemented from handler.

Definition at line 308 of file ha_perfschema.cc.

int ha_perfschema::rnd_init ( bool  scan )

virtual

rnd_init() can be called two times without rnd_end() in between (it only makes sense if scan=1). then the second call should prepare for the new table scan (e.g if rnd_init allocates the cursor, second call should position it to the start of the table, no need to deallocate and allocate it again

Implements handler.

Definition at line 287 of file ha_perfschema.cc.

Here is the call graph for this function:

int ha_perfschema::rnd_next ( uchar *  buf )

virtual

Iterator, fetch the next row.

Parameters

[out]

buf

the row fetched.

Returns

0 on success

Implements handler.

Definition at line 317 of file ha_perfschema.cc.

Here is the call graph for this function:

int ha_perfschema::rnd_pos ( uchar *  buf, uchar *  pos  )

virtual

Iterator, fetch the row at a given position.

Parameters

[out]	buf	the row fetched.
	pos	the row position

Returns

0 on success

Implements handler.

Definition at line 345 of file ha_perfschema.cc.

Here is the call graph for this function:

THR_LOCK_DATA ** ha_perfschema::store_lock ( THD *  thd, THR_LOCK_DATA **  to, enum thr_lock_type  lock_type  )

virtual

Is not invoked for non-transactional temporary tables.

Note

store_lock() can return more than one lock if the table is MERGE or partitioned.

that one can NOT rely on table->in_use in store_lock(). It may refer to a different thread if called from mysql_lock_abort_for_thread().

If the table is MERGE, store_lock() can return less locks than lock_count() claimed. This can happen when the MERGE children are not attached when this is called from another thread.

Implements handler.

Definition at line 393 of file ha_perfschema.cc.

virtual uint8 ha_perfschema::table_cache_type ( void  )

inlinevirtual

Type of table for caching query

Reimplemented from handler.

Definition at line 189 of file ha_perfschema.h.

ulonglong ha_perfschema::table_flags ( void  ) const

inlinevirtual

Capabilities of the performance schema tables.

Implements handler.

Definition at line 54 of file ha_perfschema.h.

const char* ha_perfschema::table_type ( void  ) const

inlinevirtual

The following can be called without an open handler

Implements handler.

Definition at line 47 of file ha_perfschema.h.

int ha_perfschema::truncate ( )

virtual

Quickly remove all rows from a table.

Remarks

This method is responsible for implementing MySQL's TRUNCATE TABLE statement, which is a DDL operation. As such, a engine can bypass certain integrity checks and in some cases avoid fine-grained locking (e.g. row locks) which would normally be required for a DELETE statement.

Typically, truncate is not used if it can result in integrity violation. For example, truncate is not used when a foreign key references the table, but it might be used if foreign key checks are disabled.

Engine is responsible for resetting the auto-increment counter.

The table is locked in exclusive mode.

Reimplemented from handler.

Definition at line 388 of file ha_perfschema.cc.

Here is the call graph for this function:

int ha_perfschema::update_row	(	const uchar *	old_data,
		uchar *	new_data
	)

Update a row.

Parameters

old_data	the row old values
new_data	the row new values

Returns

0 on success

Definition at line 263 of file ha_perfschema.cc.

Here is the call graph for this function:

void ha_perfschema::use_hidden_primary_key ( void  )

virtual

use_hidden_primary_key() is called in case of an update/delete when (table_flags() and HA_PRIMARY_KEY_REQUIRED_FOR_DELETE) is defined but we don't have a primary key

Reimplemented from handler.

Definition at line 252 of file ha_perfschema.cc.
