They are not particularly useful, they surely are not used
and impose a small cost for every event extracted from the
poll sets.
This commit only removes the maxadmin commands, subsequent
commits will remove the actual code.
Thread-safe version of strerror; thread local buffer used for storing
the message. The performance penalty of a thread local buffer is not
likely to be significant, since this is only called in an error
situation that anyway is likely to interrupt the normal processing.
The SQLite database is now always created on disk. This will remove the
need to dump the database users from the in-memory database to the
persisted on-disk database.
This change will also make the authentication compatible with older SQLite
implementations which lack the URI-based database strings found in newer
versions.
The DECIMAL type was not correctly converted to positive integers. The
0x80 bit was set only for negative numbers when it needed to be XOR-ed for
all values.
The DECIMAL value type is now properly handled in Avrorouter. It is
processed into an Avro double value when before it was ignored and
replaced with a zero integer.
Backported to the 2.0 branch.
An error was logged when the end of file was reached. The error should
only be logged when a partial sync marker is read and the end of file has
not been reached.
The allocation of the thread_data that is populated by the polling
mechanism must now succeed, or the process will exit. It's very
unlikely it would ever fail and it is unlikely MaxScale could would
function if it it did fail. Consequently, checks for its validity,
which anyway weren't done correctly everywhere, could be removed.
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.
