Problem: ======== When creating tables with vector indexes, if the secondary table creation fails after the main table is successfully created, the server was not properly cleaning up the main table's .ibd file. Stale file exists because create_table_impl() always called ddl_log_complete() on any error, which disables DDL log entries instead of executing them for cleanup. The main table would be left behind even though the overall CREATE TABLE operation failed. Solution: ========= Add ha_create_status enum to distinguish between different table creation failure scenarios in ha_create_table(): - HA_CREATE_SUCCESS: Table created successfully - HA_CREATE_FAILED_EARLY: Failure before storage engine file creation - HA_CREATE_FAILED_SECONDARY: Failure during secondary table creation This enum is being used in create_table_impl(): When HA_CREATE_FAILED_SECONDARY is returned, it indicates that the main table files were successfully created but secondary table creation failed. In this case, create_table_impl() calls ddl_log_revert() to execute DDL log entries and clean up the partially created main table files. When HA_CREATE_FAILED_EARLY is returned, it indicates failure before any files were created. In this case, create_table_impl() calls ddl_log_complete() to disable the DDL log entries since there's nothing to clean up. |

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
