Analysis: Problem is that both encrypted tables and compressed tables use FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION to store required metadata. Furhermore, for only compressed tables currently code skips compression. Fixes: - Only encrypted pages store key_version to FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION, no need to fix - Only compressed pages store compression algorithm to FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION, no need to fix as they have different page type FIL_PAGE_PAGE_COMPRESSED - Compressed and encrypted pages now use a new page type FIL_PAGE_PAGE_COMPRESSED_ENCRYPTED and key_version is stored on FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION and compression method is stored after FIL header similar way as compressed size, so that first FIL_PAGE_COMPRESSED_SIZE is stored followed by FIL_PAGE_COMPRESSION_METHOD - Fix buf_page_encrypt_before_write function to really compress pages if compression is enabled - Fix buf_page_decrypt_after_read function to really decompress pages if compression is used - Small style fixes |
