What was wrong: With --force-read, Log_event::read_log_event() returned a synthetic "Encrypted event" (Unknown_log_event) for every read error. A truncated event is such an error, so mariadb-binlog printed a fake event instead of stopping, and on most truncated binlogs it then never stopped at all. How it is fixed: The synthetic event is meant for encrypted events that mariadb-binlog cannot decrypt (MDEV-11319). It is now returned only for a decryption failure. Other read errors, like a truncated event or an out of memory error, are critical: continuing after them cannot produce meaningful output, so they are reported and mariadb-binlog stops as it does without --force-read. How it is tested: main.mysqlbinlog_force_read_truncated reads two truncated binlogs from std_data, one with a truncated event header and one with a truncated event body. The test loops forever without the 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:

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.
