The change N7 in MDEV-15340 (see the commit message) introduced a regression in how CAST(AS TIME), HOUR(), TIME_TO_SEC() treat datetimes '0000-00-DD mm:hh:ss' (i.e. with zero YYYYMM part and a non-zero day). These functions historically do not mix days to hours on datetime-to-time conversion. Implementations of the underlying methods used get_arg0_time() to fetch MYSQL_TIME. After MDEV-15340, get_arg0_time() went through the Time() constructor, which always adds '0000-00-DD' to hours automatically (as in all other places in the code we do mix days to hours). Changes: 1. Extending Time() to make it possible to choose a desired way of treating '0000-00-DD' (ignore or mix to hours) on datetime-to-time conversion. Adding a helper class Time::Options for this, which now describes two aspects of Time() creation: 1. Flags for get_date() 2. Days/hours mixing behavior. 2. Removing Item_func::get_arg0_time(). Using Time() directly in all affected classes. Forcing Time() to ignore (rather than mix) '0000-00-DD' in these affected classes by passing a suitable Options value. 3. Adding Time::to_seconds(), to reuse the code between Item_func_time_to_sec::decimal_op() and Item_func_time_to_sec::int_op(). 4. Item_func::get_arg0_date() now returns only a datetime value, with automatic time-to-datetime conversion if needed. An assert was added to catch attempts to pass TIME_TIME_ONLY to get_arg0_date(). All callers were checked not to pass TIME_TIME_ONLY, this revealed a bug MDEV-15363. 5. Changing Item_func_last_day::get_date() to remove the TIME_TIME_ONLY flag before calling get_arg0_date(). This fixes MDEV-15363. |

MariaDB: drop-in replacement for MySQL
MariaDB is 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. 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 Foundation and the MariaDB Corporation, 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.org/ https://mariadb.com/kb/en/ https://mariadb.com/kb/en/mariadb-vs-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-features/ https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
