All resoures now use the `state` member to describe their internal
state. This includes servers, services and monitors. This means that the
`status` keyword can be reserved for something else and it can be removed
until it is needed again.
Changed the module maturity field to `maturity` to better describe its
purpose.
The feedback system wasn't used and was starting to cause problems on
Debian 9 where the libcurl required different version of OpenSSL than what
MaxScale was linked against.
The schemarouter can now resolve database mapping conflicts in a
deterministic manner. This will fix the problem of central databases which
are replicated shards being assigned in a non-deterministic manner.
A function type rule matches a query if the query uses a function defined
in the rule. This is the desired behavior for blacklist mode operation
with `action=block`.
When in whitelist mode, all queries must match a rule to be allowed
through. For function type rules, this fact is problematic as queries that
don't use functions are blocked. The desired behavior is to allow the use
of certain functions while preventing the use of others.
The allowed set of functions should always contain the "empty set" (no
functions are used) when the filter is in whitelist mode.
The initial setting of sql_mode affects how MaxScale initially
behaves with respect to autocommit.
When 'set sql_mode=[default|oracle];" is encountered, the query
classifier and autocommit modes are adjusted accordingly.
The tee filter was missing the match/exclude functionality that was in the
previous implementation. The filter was upgraded to use PCRE2 regular
expressions instead of POSIX regular expressions.
Documented that the match/exclude patterns should use PCRE2 syntax.
The CREATE USER statement in the example document now also has a
password. This should make it more obvious that the same credentials must
work from all hosts.
MXS-1067. The CCRFilter will now look at the hints in a write-type
query. The parameter-value combinations "ccr=match" and "ccr=ignore"
are recognized and will override any regex match and ignore settings.
For the hints to work, the HintFilter needs to be present in the filter
chain before the CCRFilter.
Also ran astyle and updated documentation.
The admin interface now uses HTTP BA authentication by default. This will
prevent unrestricted access to the REST API but the authentication is by
no means secure and the HTTPS mode for the REST API should be enabled for
all production systems.
The PATCH method should now be used instead the PUT method to update
resources. As PUT request bodies should represent complete resources, the
use of PUT to update resources is no longer supported.
Altered tests to use PATCH instead of PUT for updating resources.
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 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.
Moved distribution specific commands to a new quickstart section, added a
copy-and-paste section for the generic commands. This should make it easier
to do a generic installation of MaxScale on a supported system.
