Trac requires that both default_storage_engine and default_tmp_storage_engine are InnoDB. MySQLConnector.to_sql() respecting the option for storage engine sounds good but we're directly using "CREATE TEMPORARY TABLE ..." in trac/upgrades/*.py without the to_sql() method. The "CREATE TEMPORARY TABLE ..." uses storage engine configured in the default_tmp_storage_engine. -- Jun Omae (大前 潤) -- You received this message because you are subscribed to the Google Groups "Trac Users" group.

However, rather than requiring the MySQL instance default storage engine to be set (in the system-wide my.cnf configuration), we could possibly have a trac.ini configuration option to specify the storage engine and explicitly set the default for the session before creating the tables, or use the ENGINE option when creating tables: https://dev.mysql.com/doc/refman/8.0/en/storage-engine-setting.html I'm not sure of the best solution, but we do need better documentation in: https://trac.edgewall.org/wiki/MySqlDb I will wait to see what Jun has to say before opening a new ticket. default-storage-engine=INNODB > > Unfortunately, configuration changes must be made to the database > instance, not the database. > - Ryan -- You received this message because you are subscribed to the Google Groups "Trac Users" group.

I changed the default engine of the entire database instance to InnoDB. I think you should not check the engine of the entire instance, but one of the specific database engines. This is an optimization. local. default-storage-engine=INNODB Unfortunately, configuration changes must be made to the database instance, not the database. -- You received this message because you are subscribed to the Google Groups "Trac Users" group.
