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.
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 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 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.
When log messages are written with both address and port information, IPv6
addresses can cause confusion if the normal address:port formatting is
used. The RFC 3986 suggests that all IPv6 addresses are expressed as a
bracket enclosed address optionally followed by the port that is separate
from the address by a colon.
In practice, the "all interfaces" address and port number 3306 can be
written in IPv4 numbers-and-dots notation as 0.0.0.0:3306 and in IPv6
notation as [::]:3306. Using the latter format in log messages keeps the
output consistent with all types of addresses.
The details of the standard can be found at the following addresses:

The static module capabilities are now used to query the capabilities of
filters and routers. The new RCAP_TYPE_NOAUTH capability is also taken
into use. These changes removes the need for the `is_internal_service`
function.
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.
Both the listeners and servers now support IPv6 addresses.
The namedserverfilter does not yet use the new structures and needs to be
fixed in a following commit.
Maxavro now supports reading records with the zlib deflate
algorithm.
With this change, each data block is read into memory in one IO
operation. This allows the library to decompress the data block if
necessary.
The avrorouter does not yet use compression when writing the records.
There's no point in indexing the file if it hasn't been synced to
disk. Any attempts to index the file will fail if the file still has an
open data block.
The debug assertion assumes that the table definition is always in the
binlogs. If a binlog row event without a table definition is read, debug
versions would crash even though the situation is acceptable and expected.
