Problem: ========= - During truncation of a fulltext table, InnoDB does create the table and does insert the default config fts values in fulltext common config table using create table transaction. - Before committing the create table transaction, InnoDB does update the dictionary by loading the stopword into fts cache and write the stopword configuration into fulltext common config table by creating a separate transaction. This leads to lock wait timeout error and rollbacks the transaction. - But truncate table holds dict_sys.lock and rollback also tries to acquire dict_sys.lock. This leads to assertion during rollback. Solution: ========= ha_innobase::truncate(): Commit the create table transaction before updating the dictionary after create table.
