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 help messages are now more descriptive and have usage information in
them. This should help users use the commands without relying on the
online documentation.
The authenticators should have a similar way to print diagnostic
information as filter and routers do. This allows the authenticators to
print the users in their own format.
In the future, all the diagnostic entry points should be changed so that
they return a structure that contains the information in a standard
form. This information can then be formatted in different ways by other
modules.
They are not particularly useful, they surely are not used
and impose a small cost for every event extracted from the
poll sets.
This commit only removes the maxadmin commands, subsequent
commits will remove the actual code.
This header defines some general functions and maxscale main() return
values. Most of it is still public, but there were some functions
which were moved to a core header.
The external config.h header defined functions and structures that are
intended to be used by modules. The internal header contains functions
that are used only by the MaxScale core.
To test the configuration validation and default value generation, the
functions needed to be refactored to allow parameters to be passed
directly to the function.
Some uses of monitorStart didn't pass the monitor parameters to the
function call. This caused runtime configuration of monitors to not have
any parameters as they never got their parameters.
Using the unique ID for the session is easier to use than an address. This
also allows the removal of all pointer values from the maxadmin output
which is never useful to the end user.
After upgrades, it is usually useful to see which version of MaxScale is
running. By adding a command, we can see the actual version of the running
daemon process instead of the version of the current binary.
The detailed output of the new help command was a bit too densely packed
for some commands.
Added missing values for the `alter server` command help output.
Adding a server to multiple monitors is forbidden. This should be detected
and reported to the end user.
The information provided by the config_runtime system to the client isn't
as detailed as it could be. Some sort of an error message stack should be
added so that client facing interfaces could properly report the reason
for the failure. Currently the only way to detect the reason of the
failure is to parse the log files.
The errors were detected but the code proceeded to call various functions
with bad pointers. This led to a crash if a bad server name was given to
'show server'.
The module commands operations are now listed as `commands` instead of
`functions`. The output was also formatted and an optional filtering was
added to the `list commands` call.
Maxadmin can now create and destroy monitors. The created monitors are not
started as they would be useless without added servers and configuration
parameters.
The code prevented scaling by imposing global spinlocks for the DCBs and
SESSIONs. Removing this list means that a thread-local list must be taken
into use to replace it.
The listeners aren't really destroyed and are only stopped. Further
changes are required so that they won't be started again once they have
been destroyed.
Maxadmin now supports the runtime creation of listeners. The new 'default'
value can be used to signal values that don't need to be configured and
the default value should be used.
The config_runtime.h header contains functions that can be used to
manipulate the running configuration. Currently the header contains the
function to create, add, remove and destroy servers.
The maxadmin interface to add servers to objects now allows a maximum of
11 objects to be listed. This will make it simpler to add a server to both
a monitor and a service in one command.
