Fil_init mainly refers to the initialization file opening pointer hash table. All opened files are recorded in fil_system, And the buf_pool_init memory buffer pool Initialization is constructed for the hash table searched by name, corresponding to the buf_pool_ptr array, the memory log_init of adaptive hash index is also initialized to initialize the log buffer. The default size is 512*16 k, the size of each log page is # define OS _FILE_LOG_BLOCK_SIZE 512. During the creation of the log file, the system lock is initialized without the system cache www.2cto.com lock_sys_create. A HASH table is created, lock_sys recv_recovery_from_checkpoint_start starts to execute "Recover dict_boot" to initialize the table structure cache. dict_sys creates two hash tables, which can be searched based on the table name and table ID. When the system table is initialized, four SYS_TABLES SYS_COLUMNS; initialize the insert buffer. Each tablespace corresponds to one. Read the content in the above four system tables into the trx_sys_init_at_db_start preliminary transaction structure trx_sys; creates the global purge system control structure and inits the history dict_create_or_check_foreign_constraint_tables create the other two system tables SYS_FOREIGN SYS_FOREIGN_COLS www.2cto.com startup threads.
