Take down a node other than the one we are connected to, which
will cause a group change error, and test that MaxScale catches
that and replay the transaction.
The purpose of this class is to make it easy from a test program
to access the output of the REST-API. Currently it provides only
the equivalent of "maxctrl list servers", but it can be extended
if and when additional needs arise.
Right now it's implemented so that curl is executed on the 0th
MaxScale instance, using the ssh mechanism of the test framework.
The monitor queries for logged in users with super-privileges and kicks them out to
prevent writes to master. Normal users can stay since their writes are prevented by
read_only. Also, the master-status is removed from the master manually to signal to
routers that no more writes should go to master.
If the avro block is smaller than the size of the stored data, the file
was created with a block size that was too small. Even the reference Avro
implementation can't read the file in this case.
Changes to SSL configurations is expected to be rare which allows them to
be made into immutable objects once created. This is an acceptable
compromise between performance and usability.
The message would be logged multiple times if multiple authentication
attemps failed at the same time.
Also renamed the RateLimit class method to the same as the Listener one.
The header depended on ssl.hh to include the OpenSSL headers even though
it used OpenSSL types. By fixing these dependencies the ssl.h header can
now freely include the rworker_local type which removes the need for the
hidden implementation of SSLProvider.
The class is intended to be inherited by objects that need an SSL context
and a configuration. In practice this will be servers and listeners.
The SSLContext is stored in a rworker_local shared_ptr that makes it
possible to update safely. As the copying is always done behind a lock the
cached local value always holds a valid SSLContext instance for the
duration of all function calls.
Using the pImpl idiom, the routingworker.hh header is not exposed in the
ssl.hh header. This allows the SSLProvider class to be inherited more
easily.
As server relationships are unordered, sorting them guarantees a certain
order. This fixes the MaxCtrl cluster diff test failure.
Also formatted monitor.cc sources: the indentation seems to be off.
