Worked on the MariaDB/server repository to address a user-experience issue by correcting the error message path for ALTER TABLE failures involving temporary table creation. Using C++ and SQL, introduced a dedicated, translatable error template to replace the misleading message, ensuring that errno 1005 and SQLSTATE HY000 were preserved for compatibility. The solution included updating and re-recording tests to validate the new messaging across various scenarios, such as InnoDB shadow-table creation and vector index sub-tables. This targeted fix improved clarity for developers and DBAs, streamlining troubleshooting and support during ALTER TABLE operations that use the COPY algorithm.

Apr 1, 2026April 2026: Delivered a critical user-experience improvement in MariaDB/server by correcting the error message path when ALTER TABLE fails due to temporary table creation. Introduced a dedicated translatable error template ER_CANT_CREATE_TMP_ALTER_TABLE, preserved errno 1005 / SQLSTATE HY000, and updated tests and re-recordings to reflect the new messaging. This work aligns with the 12.3 rebase and improves clarity for developers and DBAs when ALTER TABLE uses the COPY algorithm. Includes cross-path validation across InnoDB shadow-table creation and vector index sub-tables, with no changes to error codes beyond messaging. Reference: commit 69a8a1222be2b452163ddaeec0dff1d92046de8f detailing the fix for the misleading "Can't create table" error on ALTER TABLE."
