		const void *	save
	)

Reset all crash injection counters.

It's used by: SET GLOBAL innodb_ddl_log_crash_reset_debug = 1 (0).

Parameters

[in]	thd	thread handle
[in]	var	pointer to system variable
[in]	var_ptr	where the formal string goes
[in]	save	immediate result from check function

◆ operator<<()

std::ostream & operator<<	(	std::ostream &	o,
		const DDL_Record &	record
	)

Display a DDL record.

Parameters

[in,out]	o	output stream
[in]	record	DDL record to display

Returns: the output stream

◆ replace_and_insert()

static dberr_t replace_and_insert ( DDL_Record * record )
