fil_space_t::freed_ranges: Store ranges of freed page numbers. fil_space_t::last_freed_lsn: Store the most recent LSN of freeing a page. fil_space_t::freed_mutex: Protects freed_ranges, last_freed_lsn. fil_space_create(): Initialize the freed_range mutex. fil_space_free_low(): Frees the freed_range mutex. range_set: Ranges of page numbers. buf_page_create(): Removes the page from freed_ranges when page is being reused. btr_free_root(): Remove the PAGE_INDEX_ID invalidation. Because btr_free_root() and dict_drop_index_tree() are executed in the same atomic mini-transaction, there is no need to invalidate the root page. buf_release_freed_page(): Split from buf_flush_freed_page(). Skip any I/O buf_flush_freed_pages(): Get the freed ranges from tablespace and Write punch-hole or zeroes of the freed ranges. buf_flush_try_neighbors(): Handles the flushing of freed ranges. mtr_t::freed_pages: Variable to store the list of freed pages. mtr_t::add_freed_pages(): To add freed pages. mtr_t::clear_freed_pages(): To clear the freed pages. mtr_t::m_freed_in_system_tablespace: Variable to indicate whether page has been freed in system tablespace. mtr_t::m_trim_pages: Variable to indicate whether the space has been trimmed. mtr_t::commit(): Add the freed page and update the last freed lsn in the tablespace and clear the tablespace freed range if space is trimmed. file_name_t::freed_pages: Store the freed pages during recovery. file_name_t::add_freed_page(), file_name_t::remove_freed_page(): To add and remove freed page during recovery. store_freed_or_init_rec(): Store or remove the freed pages while encountering FREE_PAGE or INIT_PAGE redo log record. recv_init_crash_recovery_spaces(): Add the freed page encountered during recovery to respective tablespace. |

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:
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/
Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss, MariaDB's Zulip instance, https://mariadb.zulipchat.com/ and the #maria IRC channel on Freenode.
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip and IRC. 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.
