open_component_table()

static bool open_component_table ( THD *  thd, enum thr_lock_type  lock_type, TABLE **  table, ulong  acl_to_check  )

static

Open mysql.component table for read or write.

Note that if the table can't be locked successfully this operation will close it. Therefore it provides guarantee that it either opens and locks table or fails without leaving any tables open.

Parameters

	thd	Thread context
	lock_type	How to lock the table
[out]	table	Pointer to table structure to store the open table into.
	acl_to_check	acl type to check

Returns

Status of performed operation

Return values

true	open and lock failed - an error message is pushed into the stack.
false	success

persistent_dynamic_loader_deinit()

void persistent_dynamic_loader_deinit

(

)

persistent_dynamic_loader_init()

bool persistent_dynamic_loader_init

(

void *

thd

)

Initializes persistence store, loads all groups of components registered in component table.

Parameters

thd	Current thread execution context

Returns

Status of performed operation

Return values

false	success
true	failure
