- The test starts with the usual setup of 1 master and 3 slaves.
- Then the master is taken down and it is checked that the failover
mechanism promotes some slave to master.
- This is continued until there is a single master left (no
slaves).
The test now again blocks the nodes instead of stopping them. This should
fix the Galera cluster "corruption" which appears to happen when there are
only two nodes in the cluster which are both started and stopped.
Combined functions into one which only used different default
values. Removed unused functions. Used std::string where possible to make
their usage easier. Hid code that isn't used externally.
The same test now has two versions. In the automatic version failover
begins automatically. In the manual version failover is started with
maxadmin. The tests are otherwise identical.
Current failover code better detects weird situations and refuses to work in one.
The test server slaves have events far ahead of the master in their binlogs,
causing the failover to stop. To fix this, slave binlogs are now deleted when
a test begins.
This is a partial cherry-pick of 9f11fdd2c122c9b30548c7ab55df8dda643ec659.
Use larger BLOB type for mxs812_1, the inserted value exceeds the normal
BLOB size.
Add a baseline check into bulk_insert to verify that direct connections
work (at the moment they don't, needs an investigation).
Modified avro_alter to prevent data type conversion errors.

Updated parameter names in failover_mysqlmon_mrm.

When backend authentication failed due to errors other than wrong
credentials, the users were unconditionally reloaded. This caused a spike
of activity whenever authentication failed for other reasons.
Also fixed the test that checks for this to look for the correct error
message.
Added some code to detect server states in a consistent manner and created
the test. The multi-source replication appeared to cause problems for the
test system which needs to be resolved.
Added --force flags to most direct `mysql` calls to prevent errors from
stopping the processing of remaining commands.
The test expected the wrong error message to be in the log. To better cope
with changes in the text, the test now uses a regular expression to do the
matching.
The test is composed of a few parts.
1: Test that failover happens on master failure.
2: Test that a server with slave sql thread stopped is not promoted.
3: Test that a server with log_slave_updates=1 is promoted before others.
The CDC connector was moved to its own repository and some changes to its
interface were made. Updated build scripts, deleted old connector and
fixed code to use new interfaces.
The test suite now compiles Jansson instead of letting the CDC connector
do it. This way the connector can be used as a very simple static library
with a dependency on the Jansson library.
The CDC connector now uses a non-blocking socket for the reads. This
allows the possibility of adding read timeouts.
Added some utility functions for dealing with GTIDs and delayed the
reading of the first row.
The cdc-connector did not build on Ubuntu Trusty due to the wrong order of
linker flags. Moving the crypt and crypto linkage to be after
cdc-connector appears to fix it.
