The code in avrorouter that returned the current transaction was not very
useful and it can be acquired via the REST API in a more convenient
format.
The number of created sessions is tracked on the service level so there is
no need to track it in the avrorouter.
Removed declarations for functions that do not exist and moved code around
to reduce the scope.
The code that handles the Avro files is now fully abstracted behind the
AvroConverter class that implements the RowEventHandler interface.
The code still has some avro specific behavior in a few places (parsing of
JSON files into TableCreate objects). This can be replaced, if needed, by
querying the master server for the CREATE TABLE statements.
The various file operation related binlog events are now processed on the
upper level. This makes the actual data event processing simpler and
easier to comprehend.
Reorganized and cleaned up the binlog event processing code. Moved some of
the sanity checks into subfunctions and placed file related checks into a
separate section.
The RBR event handling related objects are now all in the rpl_events.hh
header. The intention is to combine all replication processing related
events used in the binlogrouter and avrorouter into this header to make
them reusable.
Also fixed the TableCreateEvent constructor to use an rvalue instead of
stealing an lvalue.
The value was unconditionally dereferenced even if the data type did not
have metadata. In this case the pointer would point to unallocated memory
which can lead to a crash.
The final part of the row event processing is now done by an
implementation of the EventConverter class. This makes the implementation
of different storage types easier as only the actual storage operation
needs to be implemented.
Changed TABLE_MAP to use STL containers and types. The initialization is
now done in the constructor. Removed unnecessary linkage between TABLE_MAP
and TABLE_CREATE.
When a listener is created at runtime or SSL is being enabled for an
already created listener, the ssl_verify_peer_certificate parameter can
now be defined.
If a server responds when no response was expected, dump stored
statements. This should help deduce root causes of problems relating to
unexpected responses.
The tests can now wait for a number of monitor intervals. This removes the
need to have hard-coded sleeps in the code and makes monitor tests more
robust under heavier load.
MonitorInstanceSimple is intended for simple monitors that
probe servers in a straightforward fashion. More complex monitors
can be derived directly from MonitorInstance.
