# Bug 11766634 59783: InnoDB data grows unexpectedly when inserting,
# truncating, inserting the same set of rows.
#
# Scenario:
# create table t1. Insert $recs records. check size of ibdata1.
# drop table t1. create table t1. Insert the same set of $recs
# records. The size of ibdata1 must not increase.
#
#Want to skip this test from daily Valgrind execution.
--source include/no_valgrind_without_big.inc
# Adding big test option for this test.
--source include/big_test.inc
-- source include/not_embedded.inc
-- source include/have_innodb.inc
--echo # This test case needs the innodb_file_per_table option to be disabled.
