The name of the object (i.e. the section name from the configuration
file), is now stored in the configuration object for that object.
That way, more contextual and hence morfe user friendly errors and
warnings can be generated.
Rename config::Configuration::configure() to
config::Configuration::post_configure(). Latter name makes it
unambiguously clear at what point the function is called.
Due to listener changes we cannot just keep on creating new
listeners with the same port over and over again.
Easiest to simply use a different port each time.
Trying to get the type mask of the QWBUF caused debug assertion in the query
classifier when using some commands. Now type mask is checked only when the
buffer contains MXS_COM_QUERY command.
The Listener::create method now takes a set of configuration parameters
from which it constructs a listener. This removes the duplicated code and
makes the behavior of listener creation similar to other objects in
MaxScale. It also allows the configuration parameters to be stored in the
listener object itself.
Necessary if the firewall should be able to block columns when
'ANSI_QUOTES' as enabled and " instead of backticks are used.
Without this, the following
> set @@sql_mode='ANSI_QUOTES';
> select "ssn" from person;
will not be blocked if the database firewall has been configured
to block the column ssn.
The masking filter will now consider all string arguments to
functions to be fields. This in order to prevent bypassing of
the masking with
> set @@sql_mode='ANSI_QUOTES';
> select concat("ssn") from masking;
This may lead to false positives, but no can do.
Now the desired type must be specified when getting a duration.
The type also dictates how durations without suffixes should be
interpreted.
That removes the need for remembering that to convert a returned
millisecond duration to a second duration.
Internally durations are stored in milliseconds but runtime changes
using SQL are made in seconds. Consequently, the provided value must
be multiplied by 1000 before being stored.
If set to true and if any of the other blocking related parameters
is true, then a statement that cannot be fully parsed will be blocked.
Default is true.
Storing all the runtime errors makes it possible to return all of them
them via the REST API. MaxAdmin will still only show the latest error but
MaxCtrl will now show all errors if more than one error occurs.
- Check textual prepared statements for use of columns to be masked
in conjunction with functions.
- Check binary prepared statements for use of columns to be masked
in conjunction with functions.
- Prevent creation of textual prepared statement from variable.
As the masking filter must reject statements that use columns to be
masked as arguments to functions, a statement that cannot be fully
parsed must be rejected. Unless a statement can be fully parsed we
cannot know whether such usage occurs.
