It was observed that, when doing multiple DELETE on tables:
-> if there was duplicate data to delete, then no ddls were dumped to the trace.
-> However, when tested with no data being deleted from the tables,
then ddls of the tables were getting dumped to the trace.
The problem is that store_tables_context_in_trace() is not getting
invoked, from mysql_execute_command() in all the situations.
The reason is that multi-table DELETE returned error when it had deleted duplicate rows.
Multi-table DELETE actually finds record combinations to delete,
and when it has found let's say {t1.rowX, t2.rowY, t3.rowZ}, it will attempt to
save t1.rowX in the temptable for t1, t2.rowY in the temptable for t2 and so forth.
When saving the row to be deleted, in the temp table, it can encounter error
121 (HA_ERR_FOUND_DUPP_KEY), and it is propagated to the caller.
As a fix, I have marked that there is no error when HA_ERR_FOUND_DUPP_KEY error_code is
noticed in the multi_delete::send_data()

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/

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/
