Files for PAGE_COMPRESSED tables that were created with innodb_checksum_algorithm=full_crc32 store the value of innodb_compression_algorithm at the time of the file creation. The server-wide setting of innodb_compression_algorithm may be changed after file creation. We must ignore any mismatch when opening a data file, and for writes, we must use the choice of algorithm that is stored in the file. fil_space_t::is_flags_full_crc32_equal(): Ignore the innodb_compression_algorithm but do compare innodb_page_size. fil_space_t::is_flags_non_full_crc32_equal(): Ignore the innodb_compression_algorithm.
