Marko Mäkelä 4beace3316 MDEV-21171 InnoDB is unnecessarily resetting FIL_PAGE_TYPE for full_crc32 files ... Before commit c0f47a4a58 (MDEV-12026) introduced the innodb_checksum_algorithm=full_crc32 format, it was impossible to tell if InnoDB data files contained garbage in the FIL_PAGE_TYPE header field (and possibly other fields). This is because before commit 3926673ce7 in MySQL 5.1.48, InnoDB would write uninitialized data to some fields, and because there was no way to tell with which InnoDB version a data file was created. If fil_space_t::full_crc32() holds, the data file cannot contain uninitialized garbage or invalid FIL_PAGE_TYPE, and thus fil_block_check_type() should not be invoked to correct anything.		2019-11-28 16:22:53 +02:00
