The regex strings are compiled automatically. During file parsing,
the string is compiled once using default settings to check that
the pattern is valid. Once a module asks for the compiled pcre2_code,
the pattern is compiled again with module given settings.
The regex string in the config file should be enclosed within '/ ... /'
The tests should no longer expect client session creation to fail if the
branch session creation is not successful.
The main session is kept alive so that a failure in the branch session
does not cause a failure of the main session. The main session can be
considered more important as it is what the client will use. If the branch
session fails, the failure will be logged so no information is lost.
Also added a missing configuration file and removed some extra-verbose
output in a test script.
The tee filter iterates over the available ports and finds the first
available network listener and tries to connect. This allows the use of
UNIX domain sockets with services that are targeted by the tee filter.
The tee filter now uses the local client class to clone the queries. This
imposes some restrictions on how the filter can be used but also makes
MaxScale as a whole more robust.
The local client class handles a network connection to a local service. It
is meant to be used with the tee filter so that the internal cloning of
DCBs can be removed.
The local client class connects to a port on the local host. This requires
that the user connecting to the tee filter has adequate grants to connect
locally to a MaxScale service.
After authentication for the local client is complete, the client will
pipe all queries to the service while ignoring any responses it
generates. This could be expanded so that a special handler would be given
as an argument. The handler would then handle the responses to the
queries.
Refactored the backend authentication functions so that they can be
exposed to the tee filter. This allows the tee filter to use the same
functions as the protocol modules use without having to reimplement them
inside the tee filter.
Allowing requests to be converted to raw HTTP requests allows them to be
propagated to other instances of MaxScale. This should allow multiple
MaxScales to perform the same action in a coherent manner.
A simple clustering mechanism needs to be added to make MaxScale aware of
other instances.
The module command self links now point to an endpoint that executes the
module command. Depending on the type of the module command, either a GET
or a POST request must be made.
The type and name parsing functions could move outside of allocated memory
as they didn't check for the terminating null character. Also fixed the
printf format string used when the list of used tables is being created.
Fixed CDC testing connector to abort on error and added some extra output
to the cdc_datatypes test.
The slave part of the binlogrouter replication can be ignored for
avrorouter tests. This will speed up the testing by skipping the
unnecessary restarting and configuration of slave servers.
Similar to commit c798961f211cd4435087bd4e005e9b89f3ec325d.
The CMP0026 policy causes the build to fail on CMake 2.8.12 and it isn't critical
to the functionality of the library.
Some additions to config.cc will require a recent version of PCRE2.
The system libraries may not be up to date. The pcre2 source is
bundled with MaxScale anyway, so using it is a simple way of controlling
the library version.
Explicitly specify the library location for the configure script. This
should prevent problems with different library paths that the configure
script can generate.
Fixed the expected script output for the script test.
The SSL load balancing test would fail due to a problem introduced in
connector-c 3.0 which is yet to be resolved. Due to this, the test is
disabled until an alternative way to test it is conceived.
The dbfwfilter duplicate rule detection is fixed in 2.1.
The only difference in the galera template is now in the monitor
definition and in the server address values. This fixes the unexpected
responses that some of the galera mysqltest cases suffer from.
Some tests used galera options that aren't in 2.0 which caused the tests
to fail.
Also added an upper limit to some tests to reduce excessive execution
times.
