#define HANDLER_TABLES_HASH_SIZE 120 |
void mysql_ha_cleanup | ( | THD * | thd | ) |
Close all HANDLER's tables.
thd | Thread identifier. |
Close a HANDLER table.
thd | Thread identifier. |
tables | A list of tables with the first entry to close. |
Scan the handler tables hash for matching tables.
thd | Thread identifier. |
tables | The list of tables to remove. |
void mysql_ha_flush | ( | THD * | thd | ) |
Flush (close and mark for re-open) all tables that should be should be reopen.
thd | Thread identifier. |
void mysql_ha_flush_table | ( | THD * | thd, |
const char * | db_name, | ||
const char * | table_name | ||
) |
Close cursors on the table from the HANDLER's hash.
thd | Thread context. |
db_name | Database name for the table. |
table_name | Table name. |
Close cursors of matching tables from the HANDLER's hash table.
thd | Thread identifier. |
all_tables | The list of tables to flush. |
Auxiliary function which opens or re-opens table for HANDLER statements.
thd | Thread context.. |
hash_tables | Table list element for table to open. |
false | - Success. |
true | - Failure. |
Remove matching tables from the HANDLER's hash table.
thd | Thread identifier. |
tables | The list of tables to remove. |
void mysql_ha_rm_temporary_tables | ( | THD * | thd | ) |
Remove temporary tables from the HANDLER's hash table.
The reason for having a separate function, rather than calling mysql_ha_rm_tables() is that it is not always feasible (e.g. in close_temporary_tables) to obtain a Table_ref containing the temporary tables.
thd | Thread identifier. |
void mysql_ha_set_explicit_lock_duration | ( | THD * | thd | ) |
Set explicit duration for metadata locks corresponding to open HANDLERs to protect them from being released at the end of transaction.
thd | Thread identifier. |
