Field Documentation
| ulint trx_rseg_t::id |
rollback segment id == the index of its slot in the trx system file copy
| ibool trx_rseg_t::last_del_marks |
TRUE if the last not yet purged log needs purging
| ulint trx_rseg_t::last_offset |
Byte offset of the last not yet purged log header
| ulint trx_rseg_t::last_page_no |
Page number of the last not yet purged log header in the history list; FIL_NULL if all list purged
| trx_id_t trx_rseg_t::last_trx_no |
Transaction number of the last not yet purged log
| ib_mutex_t trx_rseg_t::mutex |
mutex protecting the fields in this struct except id, which is constant
| ulint trx_rseg_t::space |
space where the rollback segment is header is placed
