# 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
|
|
|

--echo # This test case needs the innodb_file_per_table option to be disabled.
