MariaDB server is a community developed fork of MySQL server. Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry.

Oleg Smirnov be9052f80c MDEV-27027 Atomic DDL: Assertion failed upon unsuccessful multi-RENAME TABLE
When executing an atomic sequence of RENAME operations, such as:
    RENAME TABLE t1 TO t2, t3 TO t4, ...
any failure in the sequence triggers a rollback of previously completed
renames to preserve atomicity.

However, when an error occurs, `my_error()` is invoked immediately, which
sets the `thd->is_error()` flag. This premature flag setting causes
the rollback logic to misinterpret the thread state, leading to incorrect
reversion behavior and assertion failures.

To address this, the errors are now not emitted immediately but captured
and postponed. A new class `Postponed_error_handler` is introduced for
this purpose. Only after all operations are completed (including
possible DDL reversion), the captured errors are emitted.

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.

Help
