At each mini-transaction commit, the log sequence number of the mini-transaction must be written to each modified page, so that it will be available in the FIL_PAGE_LSN field when the page is being read in crash recovery. InnoDB was unnecessarily allocating redundant storage for the field, in buf_page_t::newest_modification. Let us access FIL_PAGE_LSN directly. Furthermore, on ALTER TABLE...IMPORT TABLESPACE, let us write 0 to FIL_PAGE_LSN instead of using log_sys.lsn. buf_flush_init_for_writing(), buf_flush_update_zip_checksum(), fil_encrypt_buf_for_full_crc32(), fil_encrypt_buf(), fil_space_encrypt(): Remove the parameter lsn. buf_page_get_newest_modification(): Merge with the only caller. buf_tmp_reserve_compression_buf(), buf_tmp_page_encrypt(), buf_page_encrypt(): Define static in the same compilation unit with the only caller. PageConverter::m_current_lsn: Remove. Write 0 to FIL_PAGE_LSN on ALTER TABLE...IMPORT TABLESPACE. |
