Description
In MDEV-17938 a second bool parameter was added to the function row_rename_table_for_mysql(), which is part of RENAME TABLE and also other DDL operations that rebuild tables. An earlier parameter bool commit had been removed in MDEV-25506.
In a MDEV-25292 branch bb-main-midenok-MDEV-25292, a parameter bool cmd_alter was added to row_rename_table_for_mysql(). It would have been better to replace the existing bool use_fk parameter with an enum:
enum rename_fk { |
/** ignore FOREIGN KEY constraints */ |
RENAME_IGNORE_FK= 0,
|
/** parse and enforce FOREIGN KEY constaints */ |
RENAME_FK,
|
/** Rename a table as part of a native table-rebuilding DDL operation */ |
RENAME_REBUILD,
|
/** Rename as part of ALTER TABLE...ALGORITHM=COPY */ |
RENAME_ALTER_COPY
|
};
|
Part of this change could simplify some logic around FOREIGN KEY constraints in table-rebuilding operations, such as TRUNCATE TABLE.
Another change that seems to be needed both for MDEV-25506 and MDEV-19191 is simplifying the function dict_get_referenced_table().
