The MDL_SHARED lock was introduced for an object in 5.4, but the 'TABLE_LIST'
object was not initialized with the MDL_SHARED lock when applying event with
LOAD DATA INFILE into table. So the failure is caused when checking the
MDL_SHARED lock for the object.
To fix the problem, the 'TABLE_LIST' object was initialized with the MDL_SHARED
lock when applying event with LOAD DATA INFILE into table.
mysql-test/suite/rpl/t/disabled.def:
Got rid of the line for enabling 'rpl_cross_version' test.
Fixing pb failures caused by mtr invokes the test with --tmpdir to which
there are sensitive operations in the test
and setup_fake_relay_log.inc also needed --secure-file-priv for its own separate
directory.
Fixed with removing SELECT INTO OUTFILE and deploying --exec echo instead in the marco.
The test's opt file should contain --secure-file-priv=$MYSQL_TEST_DIR as the test
operations deal with files located in $MYSQL_TEST_DIR.
mysql-test/include/setup_fake_relay_log.inc:
Refining setup_fake_relay_log.inc to not use --secure-file-priv sensitive feature.
The latter should remain available for the test.
Overriding a default value of --secure-file-priv on pb.mtr to be $MYSQLTEST_VARDIR which
makes pb's mtr happy to execute the regression test for the bug.
mysql-test/suite/rpl/t/rpl_cross_version-master.opt:
satisfying pb's mtr that uses --vardir to shm.
Overriding a default value of --secure-file-priv on pb.mtr with a value allowable
the test to pass on pb.
mysql-test/suite/rpl/t/rpl_cross_version-master.opt:
Overriding a default value of --secure-file-priv with a value allowable the test to pass on pb.
It's a regression issue.
The reason of the bug appeared to be an error introduced into 5.1 source code.
A piece of code in Create_file_log_event::do_apply_event() did not have test
coverage which made make test and pb unaware.
Fixed with inverting the old value of the return value from
Create_file_log_event::do_apply_event().
The rpl test suite is extended with `rpl_cross_version' the file to hold
regression cases similar to the current.
mysql-test/suite/rpl/r/rpl_cross_version.result:
new results file
mysql-test/suite/rpl/t/rpl_cross_version-master.opt:
options to the server to be able to start replication to itself
mysql-test/suite/rpl/t/rpl_cross_version.test:
regression test for bug#31240.
sql/log_event.cc:
Correcting the return value from Create_file_log_event::do_apply_event()
