The statistic.hh header defines a set of functions that complement the
standard library numeric functions. They differ from the standard library
functions in that they take a container reference and a pointer-to-member
as parameters and calculate the statistic based on the pointed-to member.
The 'reset_replication' module command deletes all slave connections and binlogs,
sets gtid to sequence 0 and restarts replication from the given master. Should be
only used if gtid:s are incompatible but the actual data is known to be in sync.
Event handling is now enabled by default. If the monitor cannot query the EVENTS-
table (most likely because of missing credentials), print an error suggesting to
turn the feature off.
When disabling events on a rejoining standalone server (likely a former master),
disable binlog event recording for the session. This prevents the ALTER EVENT
queries from generating binlog events.
Also added documentation and combined similar parts in the code.
This only deactivates some of the more heavy-handed features. All files have
been formatted with the new settings, which seems to have only affected lines
which were not formatted before.
The test fails since slaves are constantly going out-of-sync and cannot rejoin
the cluster. After three failovers, the cluster has three standalone server and
the monitor gets confused which server is the master. For now, limit the test to
two failovers.
The test expects the monitor to respond within 5 seconds. This is not
guaranteed to happen so waiting for a monitor interval instead of a
hard-coded duration provides for a more stable test.
Instead of using the correct version in in-source builds, a dummy file is
copied in place. This removes the need to explicitly include the
VERSION.cmake file.
If a test program needs other than the default Galera config
(e.g. log_slave_updates enabled), then it should be able to
programmatically cause galera to be restarted as part of the
TestConnections construction.
Add explicit path to the root source directory and allow invocation from
other directories. Also included qc_sqlite sources but excluded the SQLite
sources. Explicitly define the configuration in the MaxScale sources as
the one that will be used.
Changed from N invocations of uncrustify to one invocation with all files
as the program arguments. This should give a slight speedup when
formatting all sources.
When the setting up of filters for a session fails, the DCB is closed and
the client DCB's session pointer is set to NULL. This needs to be checked
in the schemarouter before the `m_client->session` pointer is used.
The act of setting the session pointer to NULL should not be necessary as
the session is freed once the reference count drops down to zero. Due to
the fact that changing this would require moderate changes in session code
means that it should not be done in a patch release as the risks are too
high.
This is somewhat questionable, as the slaves won't be able to really
replicate from the new master. However, not doing this causes the wrong
master to be selected after failover unless the new master has a majority
of slaves under it.
Added support for composite roles for 10.2 and newer versions. As
recursive CTEs are required to extract the role mappings, composite roles
aren't supported on 10.1.
