Currently execution of commit in one phase proceeds to commit by engines when binlog_commit() does not succeed. There are two issues with that: 1. absence of binlog_rollback() or lower-level `binlog_cache_data::reset()` along the following execution of the failing statement eventually will raise an assert on non-empty binlog cache, find in the MDEV description # --error assert(sql/log.cc:1712(binlog_close_connection)) # --disconnect default 2. engines, including ones that are rollback capable, commit in this particular error situation. Both effects can be observed with a new mtr test that would fail when run on a BASE of this commit. The BASE has to include MDEV-35207 et all fixes because the test is written with CREATE-TABLE-SELECTs. A new test file verifies the new behaviour to rollback including cases with a side effect of modified non-transactional engine which expose another MDEV-36027 (TODO: fix). |

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/
