UNIV_INTERN ulint innobase_get_table_cache_size ( void )

Get the current setting of the table_def_size global parameter. We do a dirty read because for one there is no synchronization object and secondly there is little harm in doing so even if we get a torn read.

Here is the caller graph for this function:

UNIV_INTERN ulonglong innobase_next_autoinc	(	ulonglong	current,
		ulonglong	need,
		ulonglong	step,
		ulonglong	offset,
		ulonglong	max_value
	)

Compute the next autoinc value.

For MySQL replication the autoincrement values can be partitioned among the nodes. The offset is the start or origin of the autoincrement value for a particular node. For n nodes the increment will be n and the offset will be in the interval [1, n]. The formula tries to allocate the next value for a particular node.

Note: This function is also called with increment set to the number of values we want to reserve for multi-value inserts e.g.,

    INSERT INTO T VALUES(), (), ();

innobase_next_autoinc() will be called with increment set to 3 where autoinc_lock_mode != TRADITIONAL because we want to reserve 3 values for the multi-value INSERT above.

Returns: the next value

Parameters

current	in: Current value
need	in: count of values needed
step	in: AUTOINC increment step
offset	in: AUTOINC offset
max_value	in: max value for type

UNIV_INTERN ulint innobase_raw_format	(	const char *	data,
		ulint	data_len,
		ulint	charset_coll,
		char *	buf,
		ulint	buf_size
	)

Formats the raw data in "data" (in InnoDB on-disk format) that is of type DATA_(CHAR|VARCHAR|MYSQL|VARMYSQL) using "charset_coll" and writes the result to "buf". The result is converted to "system_charset_info". Not more than "buf_size" bytes are written to "buf". The result is always NUL-terminated (provided buf_size > 0) and the number of bytes that were written to "buf" is returned (including the terminating NUL).

Returns: number of bytes that were written

Parameters

data	in: raw data
data_len	in: raw data length in bytes
charset_coll	in: charset collation
buf	out: output buffer
buf_size	in: output buffer size in bytes
