# Needs to be reworked. It's not possible anymore to do a non-fast alter table
# on a table that is being used by a pending transaction (transaction holds a
# metadata lock on the table).

# bug#7798
# create table t1(a int primary key, b int not null, c int, index(b));
# insert into t1 values (1,1,1), (2,2,2);
# connect (con1,localhost,root,,test);
# connect (con2,localhost,root,,test);
# connection con1;
# set autocommit=0;
# begin;
# select count(*) from t1;
# connection con2;
# ALTER TABLE t1 ADD COLUMN c int
# connection con1;
# select a from t1 where b = 2;
