In mariadb-backup --backup, we only have to invoke the undo_space_trunc and log_file_op callbacks as well as validate the mini-transaction checksums. There is absolutely no need to access recv_sys.pages or recv_spaces, or to allocate a decrypt_buf in case of innodb_encrypt_log=ON. This is what the new mode recv_sys_t::store::BACKUP will do. In the skip_the_rest: loop, the main thing is to process all FILE_ records until the end of the log is reached. Additionally, we must process INIT_PAGE and FREE_PAGE records in the same way as they would be during storing == YES. This was measured to reduce the CPU time between the messages "InnoDB: Multi-batch recovery needed at LSN" and "InnoDB: End of log at LSN" by some 20%. recv_sys_t::store: A ternary enumeration that specifies how records should be stored: NO, BACKUP, or YES. recv_sys_t::parse(), recv_sys_t::parse_mtr(), recv_sys_t::parse_pmem(): Replace template<bool store> with template<store storing>. store_freed_or_init_rec(): Simplify some logic. We can look up also the system tablespace. Reviewed by: Debarun Banerjee |

MariaDB: The innovative open source 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:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
https://mariadb.com/kb/en/new-and-old-releases/
Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
Help
More help is available from the Maria Discuss mailing list https://lists.mariadb.org/postorius/lists/discuss.lists.mariadb.org/ and MariaDB's Zulip instance, https://mariadb.zulipchat.com/
Licensing
MariaDB is specifically available only under version 2 of the GNU General Public License (GPLv2). (I.e. Without the "any later version" clause.) This is inherited from MySQL. Please see the README file in the MySQL distribution for more information.
