From: Kirill Yukhin <kyukhin@tarantool.org> To: tarantool-patches@freelists.org Cc: Kirill Yukhin <kyukhin@tarantool.org> Subject: [tarantool-patches] [PATCH 2/2] sql: block trigger creation inside a transaction Date: Thu, 15 Mar 2018 21:21:40 +0300 [thread overview] Message-ID: <789969f10fb2bc6c25bdf97aa69bcb8b5432b0a0.1521137308.git.kyukhin@tarantool.org> (raw) In-Reply-To: <cover.1521137308.git.kyukhin@tarantool.org> In-Reply-To: <cover.1521137308.git.kyukhin@tarantool.org> Since DDL is prohibited inside a transaction, this patch prohibits trigger creation and drop inside a transaction. This was done by adding dummy trigger on replace into _trigger space. This trigger only check if this not multistatement transaction. Also, make assert that schema cokie wasn't changed during transaction rollback if any. Testsuite updated as well.
