Due to there being no distinction between a temporarily stopped worker and
a permanently stopped one, we must allow posting of messages to stopped
workers.
By stopping the REST API before the workers and moving the shutdown to the
same worker that handles REST API requests, we prevent the hang on
shutdown. This also makes the signal handler signal-safe.
If a worker has been stopped, tasks must not be executed on it. To prevent
this, the calling code should check whether the worker has been
stopped. This does not prevent the case where a message is successfully
posted to a worker but the worker is stopped before it processes it.
By iterating over the servers and sending the master's charset we are
guaranteed a "known good" charset. This also solves the problem where a
deactivated server reference would be used as the charset and server
version source.
Older clients assume the plugin used for authentication is
mysql_native_password. If the client doesn't request plugin
authentication, don't treat it as an error.
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.
'build' and 'run_test' copies public ssh keys to all created VMs
Legacy code takes keys from different locations, e.g. ~/build-scripts/team_keys which
causes errors due to lack of such files.
Now public keys goes from file defined on or if not defined
from .ssh/id_rsa.pub of current host machine
mdbci call can heppen before maxsales object creation and segfault hapens
To avoid it call of ssh for 'maxscale --version-full' is moved to the end
of Testconnections constructor
Previously Maxscale version check was in the 'check_backend', but this was
removed from the tests execution process. Now 'maxscale --version-full'
is added to nodes creation function - to call_mdbci()
All RPATH setting have to be set before generation of any binary.
Defining of CMAKE_INSTALL_RPATH is moved to separate file which is called from main CMakeLists.txt in the beginning, just after install_layout.cmake
If case of MDBCI_VM_PATH variable does not have trailing slash full names of _network_config
and _lables files are defined in the wrong way: MDBCI_VM_PATH is interpreted as a part of file name
instead of direcoty name
In case when nodes/servers/replication/etc in backend are broken test can not
get proper version information and exits without doing anything.
To avoid it, test first checks backend, call fix_replication() if needed
and only after that tris to check if backend version is ok for this test
maxscale-system-test changed in order to control test environment by itself.
Every test checks which machines are running, compare with list of needed machines
and start new VMs is they are missing in the running machines list.
Tests are executiong MDBCI commands, MDBCI executable should be in the PATH
Some SQL clients may default to a different authentication plugin than
"mysql_native_password". Since this is the only one supported by MySQL-
authenticator, the client is instructed to swap its plugin.
Because runtime changes are performed one at a time, adding replication credentials
to a mariadbmon which didn't have any would cause an error to be printed, and
the monitor would not start.
This is now fixed by allowing replication_user without replication_password. This
is not an ideal solution as a configuration file with only replication_user would be
accepted. Also, when adding the credentials to a monitor, replication_user must be
given first to avoid the error.
If a routing of a queued query caused it to be put back on the query
queue, the order in which the queue was reorganized was wrong. The first
query would get appended as the last query which caused the order to be
reversed.
