Re-designed a way by that Item_trigger_field objects are arranged in memory. Item_trigger_field objects created on parsing a trigger's statement is now stored in a per statement list. All lists of Item_trigger_field objects created on parsing the whole trigger's body are organized in the structure "list of lists". So, use binary cycle to iterate every Item_trigger_field object created on parsing a trigger body. To organize the data structure 'list of lists' the new data member Item_trigger_field::next_trig_field_list is introduced that links lists in this hierarchy structure. This re-design is performed in order to avoid refences to already deleted items on re-compilation of failed trigger's statememt. Referencing to already deleted items could take place on re-parsing a trigger's statement since every Item created for a statement being re-parsed is deleted before the statement be re-parsed, but deleted items are still referenced from sp_head. So, to avoid access to dangling references a per statement list of Item_trigger_field objects are cleared right after the current SP statement be cleaned up and before re-parsing be started. |

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.
