fil_crypt_rotate_page(): Skip the key rotation for pages that carry 0 in FIL_PAGE_TYPE. This avoids not only unnecessary writes, but also failures of the recently added debug assertion in buf_flush_init_for_writing() that the FIL_PAGE_TYPE should be nonzero. Note: the debug assertion can fail if the file was originally created before MySQL 5.5. In old InnoDB versions, FIL_PAGE_TYPE was only initialized for B-tree pages, to FIL_PAGE_INDEX. For any other pages, the field could be garbage, including FIL_PAGE_INDEX. In MariaDB 10.2 and later, buf_flush_init_for_writing() would initialize the FIL_PAGE_TYPE on such old pages, but only after passing the debug assertion that insists that pages have a nonzero FIL_PAGE_TYPE. Thus, the debug assertion at the start of buf_flush_init_for_writing() can fail when upgrading from very old debug files. This assertion is only present in debug builds, not release builds. |
