Reorganized the main source file of readwritesplit. The internal functions
are first followed by the API entry points. The actual module definition
is the last declared object in the file.
The temporary table detection and handling now uses C++ containers to
store the set of temporary tables. The detection also uses the new query
classifier field info API to detect which tables and databases are
targeted.
Cleaned up the readwritesplit main header. The structs were named to their
typedef names so that no code changes are required. The structs should be
renamed if/when they are converted to proper C++ classes.
MXS-1266:
blr_slave_gtid_request() the file in slave registration request is
checked whether it exists or not and GTID file info could e set instead.
Also addded:
blr_handle_simple_select_stmt(): only mariadb10_gtid_domain is checked
for SELECT @@GLOBAL.gtid_domain_id slave request
blr_start_master_registration(): only router->mariadb10_compat is
checked before sending SELECT @@GLOBAL.gtid_domain_id to master
blr_file_create calls mxs_mkdir_all()
MASTER_USE_GTID=Slave_pos is now handled by CHANGE MASTER TO
If mariadb10_master_gtid is On
MASTER_LOG_FILE is no longer required, only MASTER_USE_GTID=Slave_pos
Slave_pos must be set before to empty value or request value:
set @@global.gtid_slave_pos = '0-10116-194';
The module commands can now produce JSON formatted output which is passed
to the caller. The output should conform to the JSON API as closely as
possible.
Currently, the REST API wraps all JSON produced by module commands inside
a meta-object of the following type:
{
"meta": <output of module command>
}
This allows the output to be JSON API conformant without modifying the
modules and allows incremental updates to code.
The addition of field types and lengths wasn't added to the avrorouter
ALTER TABLE handler. This caused crashes when an alter table was done and
new rows were inserted afterwards.
The `monitoruser` and `monitorpw` parameters were mislabeled as `monuser`
and `monpw`. To allow backwards compatibility, the `monuser` and `monpw`
still work as aliases for the correct commands.
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 module command self links now point to an endpoint that executes the
module command. Depending on the type of the module command, either a GET
or a POST request must be made.

Files are saved in GTID repo at creation time: this allows to show
files without transactions via SHOW [FULL] BINARY LOGS
The FULL keywords add domain_id and server id to the output as file
prefix: 0/10122/mysql-bin.000080
A set of the core MaxScale parameters can now be altered at runtime. This
set consists of the authentication timeouts and the admin interface
authentication. Other parameters either can't be modified due to internal
limitations or aren't sensible to modify at runtime.
Standalone events in transaction (no COMMIT event) are now handled:
the GTID is saved to gtid_maps storage.
Transaction detection assumes there is only one query_event after GTID
event with MARIADB_FL_STANDALONE flag set.
Saving GTID components into gtid_maps storage will allow to create a
hiearchical binlog cache dir.
Empty GTID for master registration can be specified with SET
@@global.gtid_slave_pos = ‘’
The schema generator program needs to add the real_type and length fields
if the data types define them.
Also fixed a bug where the real_type and length fields were checked for
generated fields.
The avro schema allows custom properties to be defined for the schema
fields. The avrorouter stored extra information about the table into the
schema for later use.
Currently, this information is only generated by the avrorouter
itself. Further improvements to the schema generator scripts need to be
done.
