A self link to the resource itself provides a convenient way for the
client to request a resource, modify it and call the self link to update
it. This removes some of the burden on the client to keep track of the
resource links by placing these in the resource itself.
The server can now be modified with a PUT request of a modified server
resource. The server resource was reorganized to have the parameters as a
separate entity from the other more general entities of the resource.
The PUT/POST functions return a more appropriate error message when no
request body is provided.
Moved some of the constant names used in server.cc into the config.h
header.
Now all relevant and working core configuration parameters have constants
for their names. This removes some of the risk that comes with the
repetition of the same parameter name in more than place.
The parameter names for monitors and servers now use a set of constant
names. This removes some of the errors caused by spelling mistakes when
the same parameter name is repeated in multiple places.
The service, filter and listener parameters should also be converted to
constants. This allows for a consistent user experience.
The admin interface now supports Basic Access authentication. This is not
a secure method of authentication and it should not be used without
unencrypted connections.
Made the admin interface port, authentication, username and password
configurable.
All whitespace in object names is now converted to a compacted format with
whitespace replaced with hyphens. If a conversion takes place, a warning
is logged.
Converted some of the tests into C++ as they directly include .cc files.
Adds a server-specific parameter, "use_proxy_protocol". If enabled,
a header string is sent to the backend when a routing session connection
changes state to MXS_AUTH_STATE_CONNECTED. The string contains the real
client IP and port.
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.
This number (defaults to 1) sets how many times mon_connect_to_db
will try to connect to a backend before returning an error. Every
connection attempt may take backend_connect_timeout seconds to
complete.
Also refactored code a bit. Renamed mon_connect_to_db to
mon_ping_or_connect_to_db, since it does not connect if the connection
is already alive.
