There's no point in indexing the file if it hasn't been synced to
disk. Any attempts to index the file will fail if the file still has an
open data block.
If MaxScale is started without the appropriate permissions to the paths
pointed by default values, the debug assertion fails even though the
parameter is valid but not usable.
The random number generator can be initialized when MaxScale's other
systems are being initialized. This removes the need to initialized it
when the function is used for the first time.
SHOW VARIABLES LIKE 'SERVER_UUID' and SET @slave_uuid are meant only
for MySQL 5.6/7 master registration.
If MariaDB 10 compatibility is set then skip these useless requests.
Added a section to the release notes that tells the fact that the
readwritesplit, schemarouter and binlogrouter now also accept the values
of router_options as parameters.
NullFilter is a filter module that does nothing, except reports
capabilities as defined in the configuration file. It's purpose
is only to make it simple to benchmark the performance impact
various routing capabilities have.
Note that since getCapabilities() currently does *not* take an
instance pointer as parameter, all NullFilter instances will
report the same capabilities, the ones specified for the last
filter to have been loaded.
- Add note about filters having become available in 2.1.
- Add insertstream to release notes and change log.
- Add complete example to cache documentation.

Removed unused spinlocks from DCBs, sessions and the MySQL protocol
structs. They were used in a context where only one thread has access to
the structure.
Removed unused member variables from DCBs.

The use of monitors in services isn't complete but this was not in the
documentation. A more complete solution should be done at a later date and
the current documentation should be removed.
The debug assertion assumes that the table definition is always in the
binlogs. If a binlog row event without a table definition is read, debug
versions would crash even though the situation is acceptable and expected.
The authenticators should have a similar way to print diagnostic
information as filter and routers do. This allows the authenticators to
print the users in their own format.
In the future, all the diagnostic entry points should be changed so that
they return a structure that contains the information in a standard
form. This information can then be formatted in different ways by other
modules.
MariaDB and others match grants first by exact hostname/IP and then by
wildcard. If there are no exact matches, the wildcard grant should be
picked. This can be tested by having different passwords for localhost and
remote address.
The SQLite based authentication should first check for an exact match and
then only after that should it try to match the hostname to a wildcard
grant.
