The password values are now masked with asterisks. This tells whether a
password is set or not but it does not expose any information about the
password itself.
It's now possible to specify in the config parameter declaration
that the smallest allowed unit is seconds. For parameters whose
granularity is seconds, allowing to specify a duration in
milliseconds would open up a possibility for hard to detect errors.
Added a new module parameter type to be used for parameters
that specify a duration. With the suffixes 'h', 'm', 's' and
'ms' the duration can be specified in hours, minutes, seconds
or milliseconds, respectively.
Irrespective of how the duration is specified, it is always
returned as milliseconds.
For backward compatibility, when a duration value is read it must
be specifed how a value *not* defined using a suffix should be
interpreted; as seconds or milliseconds.
value = param->get_duration(name, mxs::config::INTERPRET_AS_SECONDS);
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
Parameter deprecation on the module level means that the parameter should
no longer be used but using it will not cause an error. If a deprecated
parameter is used, it will be removed from the configuration.
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 '/ ... /'
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"'.
The modules, their types and default values are exposed via the
/maxscale/modules resource. Currently, only a list of resources can be
exposed as the externally exposed module object (MXS_MODULE) does not have
the name and type information in it.
A module can now declare a path parameter for a directory that does not
yet exist. If the directory does not exist, MaxScale will create the
directory with the requested permissions.
The static capabilities declared in getCapabilities allows certain
capabilities to be queried before instances are created. The intended use
of this capability is to remove the need for the `is_internal_service`
function.
This is a list of servers, separated by commas. When queried as a
config setting, returns a null-terminated array of SERVER*:s. The
commit includes a serverlist parsing function, which should probably
be used anywhere a similarly formed string is parsed.
The type represents byte sizes used for configuring buffers and file
sizes. The supported suffixes for binary units are k, m, g and t in both
upper and lower case.
If the enums are converted to the acutual enum values before they are
returned, this removes the need for the modules to process the enum
strings to enum values. This allows modules to use enumerations with
minimal effort.
