The configuration checks for module parameters are now fully in use. By
removing the hard-coded values from the list of accepted values, the
modules take control of what parameters are accepted.
The type represents byte sizes used for configuring buffers and file
sizes. The supported suffixes for binary units are k, m, g and t in both
upper and lower case.
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.
To test the configuration validation and default value generation, the
functions needed to be refactored to allow parameters to be passed
directly to the function.
When a monitor is created at runtime, it also needs to have the default
parameters. Ideally, this would be done when the monitor is allocated but
because of the way the configuration is processed, we need to do it after
user defined parameters are added.
Some uses of monitorStart didn't pass the monitor parameters to the
function call. This caused runtime configuration of monitors to not have
any parameters as they never got their parameters.
- All (but the printing/debug functions) are now in snake_case.
- Functions made const correct.
- All function prototypes now have named arguments.
Documentation still to be moved, and file possibly split into
include/mascale/server.h and server/core/maxscale/server.h
Previously, these were discarded. This patch adds a function to
"merge" the mask to the ip so that it's in the form which
normalize_hostname expects (using % as wildcard). Only simple masks
with 255:s and 0:s are accepted. Any other combinations may leave
the hostname in a garbled state which will cause it to be discarded
later.
This change now ties the pieces together and implements tha
functionality required of the masking filter. Note thought that
this is still work in progress and changes will follow.
- LEncInt : Class for dealing with length encoded integers
- LEncString : Class for dealing with length encoded strings
- ComPacket : Base-class for all packet classes.
- ComRequest : Base-class for all requests.
- ComResponse : Base-class for all responses.
- ComQueryResponse
- ComQueryResponse::ColumnDef
- ComQueryResponse::Row
Common to these all is that they are very thin, and basically only
make it easier to what anyway needs to be done, if the equivalent
is used by directly accessing the packet buffer.
Now these are private for the masking filter, but may be moved under
masxcale/include if/when the general usefulness has been established.
Closer is a template using which C-style resources can be managed
in a C++ context where exceptions can occur. By placing a C resource
in a Closer instance, it is certain the resource will be freed when
the closing scope is exited irrespective of whether that occurs due
to the normal control flow, due to a return statement or an exception
having been thrown.
To be used with Closer, the CloserTraits template must be specialized
for the type in question. With this change specializations are provided
for FILE*, json_t*, pcre_code* and pcre2_match_data*.

Now both qc_mysqlembedded and qc_sqlite return the same stuff
for the same statement, and both include also operators in
addition to pure functions. Whether that is the right approach,
is still subject to debate.
However, if we want to make it possible to disable e.g. the
use of concat as in "select concat(a) from t", where a is a string,
to prevent the bypassing of the masking filter, then conceptually
it should be possible to prevent "select a+0 from t", where a is an
int, as well.
The setting up and the initialization of the query classifier has
now been separated. The gateway explicitly sets up the query
classifier (i.e. chooses which one to use and what arguments to
provide), but the actual initialization is performed as part of
the general module initialization.
