Function Documentation

int handlemap_db_count

(

const char *

dir

)

count the number of database instances in a given directory (this is used for checking that the number of db matches the number of threads)

Definition at line 609 of file handle_mapping_db.c.

int handlemap_db_delete

(

nfs23_map_handle_t *

p_in_nfs23_digest

)

Submit a db 'delete' request. The request is inserted in the appropriate db queue. (always asynchronous)

Definition at line 848 of file handle_mapping_db.c.

int handlemap_db_flush

(

)

Wait for all queues to be empty and all current DB request to be done.

Definition at line 885 of file handle_mapping_db.c.

int handlemap_db_init	(	const char *	db_dir,
		const char *	tmp_dir,
		unsigned int	db_count,
		unsigned int	nb_dbop_prealloc,
		int	synchronous_insert
	)

Initialize databases access (init DB queues, start threads, establish DB connections, and create db schema if it was empty).

Initialize databases access

• init DB queues
• start threads
• establish DB connections
• create db schema if it was empty

int handlemap_db_insert	(	nfs23_map_handle_t *	p_in_nfs23_digest,
		fsal_handle_t *	p_in_handle
	)

Submit a db 'insert' request. The request is inserted in the appropriate db queue.

Definition at line 804 of file handle_mapping_db.c.

int handlemap_db_reaload_all

(

hash_table_t *

target_hash

)

Gives the order to each DB thread to reload the content of its database and insert it to the hash table. The function blocks until all threads have loaded their data.
