Detailed Description
Recovery system data structure
Field Documentation
| hash_table_t* recv_sys_t::addr_hash |
hash table of file addresses of pages
| ibool recv_sys_t::apply_batch_on |
this is TRUE when a log rec application batch is running
| ibool recv_sys_t::apply_log_recs |
this is TRUE when log rec application to pages is allowed; this flag tells the i/o-handler if it should do log record application
| byte* recv_sys_t::buf |
buffer for parsing log records
| ibool recv_sys_t::found_corrupt_log |
this is set to TRUE if we during log scan find a corrupt log block, or a corrupt log record, or there is a log parsing buffer overflow
| mem_heap_t* recv_sys_t::heap |
memory heap of log records and file addresses
| byte* recv_sys_t::last_block |
possible incomplete last recovered log block
| byte* recv_sys_t::last_block_buf_start |
the nonaligned start address of the preceding buffer
| ulint recv_sys_t::last_log_buf_size |
size of the log buffer when the database last time wrote to the log
| ulint recv_sys_t::len |
amount of data in buf
| lsn_t recv_sys_t::limit_lsn |
recovery should be made at most up to this lsn
| lsn_t recv_sys_t::lsn |
log sequence number
| ib_mutex_t recv_sys_t::mutex |
mutex protecting the fields apply_log_recs, n_addrs, and the state field in each recv_addr struct
| ulint recv_sys_t::n_addrs |
number of not processed hashed file addresses in the hash table
| lsn_t recv_sys_t::parse_start_lsn |
this is the lsn from which we were able to start parsing log records and adding them to the hash table; zero if a suitable start point not found yet
| lsn_t recv_sys_t::recovered_lsn |
the log records have been parsed up to this lsn
| ulint recv_sys_t::recovered_offset |
start offset of non-parsed log records in buf
| ulint recv_sys_t::scanned_checkpoint_no |
the log data has been scanned up to this checkpoint number (lowest 4 bytes)
| lsn_t recv_sys_t::scanned_lsn |
the log data has been scanned up to this lsn
| ib_mutex_t recv_sys_t::writer_mutex |
mutex coordinating flushing between recv_writer_thread and the recovery thread.
