Problem: we may create a deadlock committing changes in the mysql_alter_table() when LOCK_open is set. Moreover, "in some variants of the ALTER TABLE commit happens earlier, outside of LOCK_open, in other later - inside. It's no good, a storage engine code that is called in between could expect a consistency - either there is a transaction or there is not". Fix: move the commit to happen earlier and outside of the LOCK_open. mysql-test/r/innodb_mysql.result: Fix for bug #28652: MySQL (with-debug=full) asserts when alter table operations - test result. mysql-test/t/innodb_mysql.test: Fix for bug #28652: MySQL (with-debug=full) asserts when alter table operations - test case. sql/sql_table.cc: Fix for bug #28652: MySQL (with-debug=full) asserts when alter table operations - commit moved to happen earlier in the mysql_alter_table(), now we commit changes at the same time as in case when a temporary table is used. |
