The flags trx->active_commit_ordered and trx->active_prepare got cleared in trx_init() during the fast part of commit (ie. commit_ordered()). This is too early, then the values are lost when processing reaches trx_commit_complete_for_mysql(). This caused the MDEV-232 optimization to be omitted, adding an extra fsync() at the end of commit when using the legacy binlog and causing severe performance regression. The values of trx->active_commit_ordered and trx->active_prepare must persist to the end of commit procesing, same as trx->is_registered. This is done in this patch, active_commit_ordered and active_prepare are cleared in trx_deregister_from_2pc() together with trx->is_registered in trx_deregister_from_2pc(), and asserted to be cleared when trx->is_registered is set for a following transaction.

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/
