If a relationship isn't defined, it should not be removed. Only if a
relationship is change to a null relationship, should it be removed.
Also fixed the maxctrl test suite to verify that both it and the REST API
tests pass.
The data of the relationship should be set to null to delete the
relationship. Conceptually it is different from setting it to an empty
relationship but in practice both lead to the same end result.
Updated tests to use correct relationships and added test cases for
detection of invalid relationships.
The service now uses a std::vector<SFilterDef> to store the filters it
uses. Most internal parts deal with the SFilterDef but debugcmd.cc still
moves raw pointers around (needs to be changed).
Replaced the previous RESULTSET with the new implementation. As the new
ResultSet doesn't have a JSON streaming capability, the MaxInfo JSON
interface has been removed. This should not be a big problem as the REST
API offers the same information in a more secure and structured way.
The filter implementation is now fully hidden. Also converted it to a C++
struct allocated with new and stored the filters in a global list instead
of embedding the list in the object itself.
Changed the filter_alloc function to fully initialize the filter. This
means that if filter_alloc returns a non-NULL pointer, the filter was
successfully loaded and an instance was successfully created.
-Wunused-result warning in test_logthrottling.cc was causing error when
trying to build MaxScale from source. This warning can be silenced with by
putting the function triggering the warning in if-clause.
The test cases allocated servers in a way that doesn't comfortably suit
the way the servers are now allocated. Adding a helper C++ class to load
module defaults makes it easier to do explicit server initialization in
tests.
The binlogrouter was also fixed in this commit as it uses servers much
like a test would use.
The common monitor parameters are now stored as module-style
parameters. This makes the error reporting as well as the type checks for
the parameters consistent with parameters declared by the modules.
The same mechanism that is used for modules can be used for the
configuration of the core objects. This removes the need for the redundant
code that validates various values that is already present in the code
that modules use.
Now takes a structure that, if present, enables the query
classification caching and specifies the properties of the
cache.
For the time being no actual properties are yet available.
The id has now been moved from mxs::Worker to mxs::RoutingWorker
and the implications are felt in many places.
The primary need for the id was to be able to access worker specfic
data, maintained outside of a routing worker, when given a worker
(the id is used to index into an array). Slightly related to that
was the need to be able to iterate over all workers. That obviously
implies some kind of collection.
That causes all sorts of issues if there is a need for being able
to create and destroy a worker at runtime. With the id removed from
mxs::Worker all those issues are gone, and its perfectly ok to create
and destory mxs::Workers as needed.
Further, while there is a need to broadcast a particular message to
all _routing_ workers, it hardly makes sense to broadcast a particular
message too _all_ workers. Consequently, only routing workers are kept
in a collection and all static member functions dealing with all
workers (e.g. broadcast) have now been moved to mxs::RoutingWorker.
Now, instead of passing the id around we instead deal directly
with the worker pointer. Later the data in all those external arrays
will be moved into mxs::[Worker|RoutingWorker] so that worker related
data is maintained in exactly one place.
Look for the expected message several times, with short sleeps in
between. That way we will not sleep more than necessary, yet will
not immediately give up either.
MaxScale now defines events for which the syslog
facility and level can explicitly be defined by the
administrator. Currently there is only one such
event, namelt AUTHENTICATION_FAILURE.
In a subsequent commit, config.cc will be modified so
that event-related configuration parameters are passed
to event::configure() and in another subsequent commit
the authenticators will be modifed to use this mechanism.
In practice a line like:
MXS_WARNING("%s: login attempt for user '%s'@[%s]:%s, "
"authentication failed.",
dcb->service->name, client_data->user,
dcb->remote, dcb->path);
will be changed to
MXS_LOG_EVENT(event::AUTHENTICATION_FAILURE,
"%s: login attempt for user '%s'@[%s]:%s, "
"authentication failed.",
dcb->service->name, client_data->user,
dcb->remote, dcb->path);
-Wunused-result warning in test_logthrottling.cc was causing error when
trying to build MaxScale from source. This warning can be silenced with by
putting the function triggering the warning in if-clause.
Single spot where an existing hint ptr was overwritten. Removed gwbuf_add_hint()
because it was adding hints at the opposite end compared to functions in hint.h.
Added hint_splice() to replace.
