The function now returns the compiled code or null or error. Also,
instead of capcount, it writes the ovector size. The ovector pointer
can be null. Removed the other config_get_compiled_regex()-function
and replaced it with the refactored function since they are almost
identical.
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 module commands can now produce JSON formatted output which is passed
to the caller. The output should conform to the JSON API as closely as
possible.
Currently, the REST API wraps all JSON produced by module commands inside
a meta-object of the following type:
{
"meta": <output of module command>
}
This allows the output to be JSON API conformant without modifying the
modules and allows incremental updates to code.
This is for backwards compatibility to allow current modules to use
the automatically compiled regex parameters. The enforcement should
be restored in a later version. A warning is output for every non-
enclosed regex.
Similar changes are also applied for QUOTED_STRING.
The MySQL monitor replication_heartbeat table now uses the default storage
engine of the database when creating the table. Most of the time the
default is InnoDB which makes the table crash-safe.
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 `monitoruser` and `monitorpw` parameters were mislabeled as `monuser`
and `monpw`. To allow backwards compatibility, the `monuser` and `monpw`
still work as aliases for the correct commands.
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 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.
A quoted string is a string enclosed in '"':s. This makes it clear
where the string begins and ends, avoiding ambiguity with whitespace.
After the config file has been loaded, the '"':s at the beginning
and at the end of the string are erased. Querying the config value
with config_get_string() will return this de-quoted value.
For example, if the config file reads 'my_string="test""', the actual
string will be 'test"'.
Files are saved in GTID repo at creation time: this allows to show
files without transactions via SHOW [FULL] BINARY LOGS
The FULL keywords add domain_id and server id to the output as file
prefix: 0/10122/mysql-bin.000080
The /maxscale/ resource now supports PUT requests which modify core
parameters. As not all parameters can be changed at runtime, only
modifications to parameters that support runtime configuration are
allowed.
A set of the core MaxScale parameters can now be altered at runtime. This
set consists of the authentication timeouts and the admin interface
authentication. Other parameters either can't be modified due to internal
limitations or aren't sensible to modify at runtime.
