[tarantool-patches] [PATCH v3 1/5] refactoring: remove exceptions from triggers except alter.cc
Ilya Kosarev
i.kosarev at tarantool.org
Wed Sep 11 16:05:15 MSK 2019
Triggers' signatures are updated so that they will be able
to return error codes instead of throwing exceptions.
In files except alter.cc triggers don't throw exceptions any more.
