- Store the deferred tablespace name while loading the tablespace
for backup process.
- Mariabackup stores the list of space ids which has page0 INIT_PAGE
records. backup_first_page_op() and first_page_init() was introduced
to track the page0 INIT_PAGE records.
- backup_file_op() and log_file_op() was changed to handle
FILE_MODIFY redo log records. It is used to identify the
deferred tablespace space id.
- Whenever file operation redo log was processed by backup,
backup_file_op() should check whether the space name exist
in deferred tablespace. If it is then it needs to store the
space id, name when FILE_MODIFY, FILE_RENAME redo log processed
and it should delete the tablespace name from defer list in other
cases.
- backup_fix_ddl() should check whether deferred tablespace has
any page0 init records. If it is then consider the tablespace
as newly created tablespace. If not then backup should try
to reload the tablespace with SRV_BACKUP_NO_DEFER mode to
avoid the deferring of tablespace.
