South migrate error, InnoDB: ROW_FORMAT=DYNAMIC requires innodb_file_format > Antelope

Question

I migrate data occur error.
I tried to run raw sql below:
ALTER TABLE wxwall_participation ADD COLUMN event INT DEFAULT 0
ALTER TABLE wxwall_scene ADD COLUMN welcome_msg VARCHAR(400) NULL
They work very well, which make me comfuse.How can I solve this problem?

error detail:

 - Migrating forwards to 0002_auto__add_field_participation_event__add_field_scene_welcome_msg.
 > wxwall:0002_auto__add_field_participation_event__add_field_scene_welcome_msg
 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running
 ! schema-altering statements in transactions, we have had
 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   - no dry run output for delete_foreign_key() due to dynamic DDL, sorry
   = ALTER TABLE `wxwall_participation` DROP COLUMN `event` CASCADE; []
   - no dry run output for delete_foreign_key() due to dynamic DDL, sorry
   = ALTER TABLE `wxwall_scene` DROP COLUMN `welcome_msg` CASCADE; []

 ! The South developers regret this has happened, and would
 ! like to gently persuade you to consider a slightly
 ! easier-to-deal-with DBMS (one that supports DDL transactions)
 ! NOTE: The error which caused the migration to fail is further up.

_mysql_exceptions.Warning: InnoDB: ROW_FORMAT=DYNAMIC requires innodb_file_format > Antelope.

Answer 1

I find the problem.The key is innodb_file_format
I restore data from a production database backup.Production's mysql config innodb_file_format=Barracuda, but my local is default value Antelope.

I think a more proper error message would be ROW_FORMAT=DYNAMIC requires innodb_file_format =Barracuda.
What should I do is just set innodb_file_format = Barracuda in my.ini, then everything would be fine.
