During mariadb-backup --backup, a table could be renamed, created and dropped. We could have both oldname.ibd and oldname.new, and one of the files would be deleted before the InnoDB recovery starts. The desired end result would be that we will recover both oldname.ibd and newname.ibd. During normal crash recovery, at most one file operation (create, rename, delete) may require to be replayed from the write-ahead log before the DDL recovery starts. deferred_spaces.create(): In mariadb-backup --prepare, try to create the file in case it does not exist. fil_name_process(): Display a message about not found files not only if innodb_force_recovery is set, but also in mariadb-backup --prepare. If we are processing a FILE_RENAME for a tablespace whose recovery is deferred, suppress the message and adjust the file name in case fil_ibd_load() returns FIL_LOAD_NOT_FOUND or FIL_LOAD_DEFER. fil_ibd_load(): Remove a redundant file name comparison. The caller already compared that the file names are different. We used to wrongly return FIL_LOAD_OK instead of FIL_LOAD_ID_CHANGED if only the schema name differed, such as a/t1.ibd and b/t1.ibd.

MariaDB: The open source relational database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss, MariaDB's Zulip instance, https://mariadb.zulipchat.com/
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
Licensing
