The replication_manager is only designed for systems that have yum
installed which means it will always fail on non-RHEL/CentOS systems.
The query threads in mxs1323_stress were not checking whether the test had
ended while they were executing the queries. This caused test timeouts as
the queries can take a relatively long time.
The tests should not drop the test database and then recreate it. This
adds an unnecessary burden on replication which will cause false positives
when replication is not fast enough.
This is commit `2410c23e6664bef7e449dfd5a767121f309559fe` from develop
cherry-picked to 2.1.
When a backend is waiting for a response but no statement is stored for
the session, the buffer where the stored statement is copied is not
modified. This means that it needs to be initialized to a NULL value.
Added a test that checks that the behavior works as expected even with
persistent connections. A second test reproduces the crash by executing
parallel SET commands while slaves are blocked.
There is still a behavioral problem in readwritesplit. If a session
command is being executed and it fails on a slave, an error is sent to the
client. In this case it would not be necessary to close the session if the
master is still alive.
As the test does a lot of large inserts, the timeouts can be triggered at
times when the test is not actually stuck but just waiting for the insert
to complete. Increasing the timeout from 10 to 30 seconds should give it
enough time to finish processing.
When an internal connection is created, the SQL_MODE of the connection
should be set to a known default. The empty SQL_MODE allows consistent
functionality for all backend server versions.
The avrorouter failed to detect ALTER TABLE statements which caused a
regression. Extended the alter table tests to parse the JSON for more
strict validation of test results.
The test dropped the 'test' database which is heavily used both for
checking functionality and running tests. A better alternative is to use a
custom database that is only used by this test.
The masking filter now has a default fill value, so that if a
provided value does not match, then "X" is used.
The tests were modified to use "Y" as an explicitly provided
fill value (to distinguish from the default "X") and the results
were the default fill value would kick in were modified accordingly.
The timeout is hit very often if the cluster fixing takes some time. This
causes false positives so the timeout should be stopped before attempting
to fix the cluster.
The test seems to fail when executed outside of a debugger. A delay
between creating the connections and checking the connection count appears
to fix the problem.
Refactored the test to use stack allocated objects and favored assertion
style functions over conditional clauses with failing assertions inside
them.
The type and name parsing functions could move outside of allocated memory
as they didn't check for the terminating null character. Also fixed the
printf format string used when the list of used tables is being created.
Fixed CDC testing connector to abort on error and added some extra output
to the cdc_datatypes test.
The slave part of the binlogrouter replication can be ignored for
avrorouter tests. This will speed up the testing by skipping the
unnecessary restarting and configuration of slave servers.
Fixed the expected script output for the script test.
The SSL load balancing test would fail due to a problem introduced in
connector-c 3.0 which is yet to be resolved. Due to this, the test is
disabled until an alternative way to test it is conceived.
The dbfwfilter duplicate rule detection is fixed in 2.1.
The only difference in the galera template is now in the monitor
definition and in the server address values. This fixes the unexpected
responses that some of the galera mysqltest cases suffer from.
Some tests used galera options that aren't in 2.0 which caused the tests
to fail.
Also added an upper limit to some tests to reduce excessive execution
times.
