Now that the query classifier can be given COM_STMT_PREPARE packets
in addition to COM_QUERY packets, binary prepared statements will
be subject to the same analyses as any other statement.
All modules now declare a name for the module. This is name is added as a
prefix to all messages logged by a module. The prefix should help
determine which part of the system logs a message.
The filter converts bulk inserts inside transactions into LOAD DATA LOCAL
INFILE statements. This allows multiple INSERT statements to be streamed
in a more efficient manner.
The module should be in the experimental package as it is still at an
experimental stage.
The module commands now support an optional flag for arguments that when
enabled checks that the argument module name matches the registered domain
name. This can be used to enforce argument type validity for arguments
that are given to modules that expect objects of a certain type.
For example, this is used by the cache and dbfwfilter to prevent valid
filters but of the wrong type being given as arguments.
Tee no longer uses the dummy_filterdef FILTER_DEF member, so
it can be removed. That means that filter_free() can be removed
from the public filter.h include.
The filters don't need to process relative paths as the core handles
that. All path parameters are interpreted as relative to the module
configuration directory, /etc/maxscale.modules.d/.
Only columns that are of string kind are now subject to masking.
With a textual resultset it would be possible to mask anything the
same way, but with a binary resultset it is not. Thus, so that the
result is not dependent upon whether the resultset happens to be
textual or not, only string fields are accessed. Documentation to be
updated in a separate change.
The utility classes have now also been rearranged somewhat.
The maskingfilter still does some processing due to the fact that it
accepts relative pathnames. This should ideally done by the core in a
controlled manner and for all path parameters.
The function is intended to be used with string parameters that are
optional and are copied when defined. This removes the need to copy the
string to a local variable to perform checks on the value.
Moved the qlafilter parameters to module options. This removes the need to
parse the options in the filter.
Split the options into separate parameters. This allows common options to
be combined as enumerations under common parameters.
