Function Documentation

ib_handle_errors()

bool ib_handle_errors	(	dberr_t *	new_err,
		trx_t *	trx,
		que_thr_t *	thr,
		trx_savept_t *	savept,
		bool	is_sdi
	)

Handles user errors and lock waits detected by the database engine.

Parameters

[out]	new_err	possible new error encountered in lock wait, or if no new error, the value of trx->error_state at the entry of this function
[in]	trx	transaction
[in]	thr	query thread
[in]	savept	savepoint or NULL
[in]	is_sdi	true if table is SDI

Returns

true if it was a lock wait and we should continue running the query thread.

ib_trx_lock_table_with_retry()

dberr_t ib_trx_lock_table_with_retry	(	trx_t *	trx,
		dict_table_t *	table,
		enum lock_mode	mode
	)

in: lock mode

in: lock mode

Returns

error code or DB_SUCCESS

Parameters

trx	in/out: transaction
table	in: table to lock
mode	in: LOCK_X or LOCK_S
