Member Data Documentation

hash_table_t* recv_sys_t::addr_hash

hash table of file addresses of pages

Definition at line 431 of file log0recv.h.

ibool recv_sys_t::apply_batch_on

this is TRUE when a log rec application batch is running

Definition at line 386 of file log0recv.h.

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

Definition at line 381 of file log0recv.h.

byte* recv_sys_t::buf

buffer for parsing log records

Definition at line 398 of file log0recv.h.

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

Definition at line 420 of file log0recv.h.

mem_heap_t* recv_sys_t::heap

memory heap of log records and file addresses

Definition at line 429 of file log0recv.h.

byte* recv_sys_t::last_block

possible incomplete last recovered log block

Definition at line 393 of file log0recv.h.

byte* recv_sys_t::last_block_buf_start

the nonaligned start address of the preceding buffer

Definition at line 396 of file log0recv.h.

ulint recv_sys_t::last_log_buf_size

size of the log buffer when the database last time wrote to the log

Definition at line 390 of file log0recv.h.

ulint recv_sys_t::len

amount of data in buf

Definition at line 399 of file log0recv.h.

lsn_t recv_sys_t::limit_lsn

recovery should be made at most up to this lsn

Definition at line 417 of file log0recv.h.

lsn_t recv_sys_t::lsn

log sequence number

Definition at line 388 of file log0recv.h.

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

Definition at line 373 of file log0recv.h.

ulint recv_sys_t::n_addrs

number of not processed hashed file addresses in the hash table

Definition at line 432 of file log0recv.h.

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

Definition at line 401 of file log0recv.h.

lsn_t recv_sys_t::recovered_lsn

the log records have been parsed up to this lsn

Definition at line 415 of file log0recv.h.

ulint recv_sys_t::recovered_offset

start offset of non-parsed log records in buf

Definition at line 412 of file log0recv.h.

ulint recv_sys_t::scanned_checkpoint_no

the log data has been scanned up to this checkpoint number (lowest 4 bytes)

Definition at line 409 of file log0recv.h.

lsn_t recv_sys_t::scanned_lsn

the log data has been scanned up to this lsn

Definition at line 406 of file log0recv.h.

ib_mutex_t recv_sys_t::writer_mutex

mutex coordinating flushing between recv_writer_thread and the recovery thread.

Definition at line 376 of file log0recv.h.
