The auxiliary status bits for the server were treated as if they changed
the real state of the server. The stale status bits don't affect the real
state of the server so they should be ignored when monitors check for
state changes in servers.
This function will return the preparable statement of a PREPARE
statement as a COM_QUERY GWBUF. That is, once obtained, the normal
query classifier functions can be used for obtaining information
about the preparable statement itself.
- Only types of fixed size used in API interface
- The actual function return value specifies whether the parsing
process succeeded, while "logical" return values are returned
as out arguments.
The wrapper function currently ignores the function return value.
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.
The header is divided into two parts, an external and an internal one. The
actual splitting is done in a later commit and this commit only prepares
the header for the split.
The module commands now support an optional flag for arguments that when
enabled checks that the argument module name matches the registered domain
name. This can be used to enforce argument type validity for arguments
that are given to modules that expect objects of a certain type.
For example, this is used by the cache and dbfwfilter to prevent valid
filters but of the wrong type being given as arguments.
This directory is intended to be the default working directory for
relative pathname resolution. The actual implementation for
MXS_MODULE_PARAM_PATH is done at a later step.
This removes parts of the nearly identical code from all monitors.
The removal of monitor type specific event checking is done based on the
assumption that only the monitor that is monitoring the server can be the
cause for a state change. This removes the need to actually check that the
state change is relevant for each monitor and allows the event handling to
be moved into the core.
The configuration checks for module parameters are now fully in use. By
removing the hard-coded values from the list of accepted values, the
modules take control of what parameters are accepted.
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.
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.
When a monitor is created at runtime, it also needs to have the default
parameters. Ideally, this would be done when the monitor is allocated but
because of the way the configuration is processed, we need to do it after
user defined parameters are added.
- All (but the printing/debug functions) are now in snake_case.
- Functions made const correct.
- All function prototypes now have named arguments.
Documentation still to be moved, and file possibly split into
include/mascale/server.h and server/core/maxscale/server.h
The setting up and the initialization of the query classifier has
now been separated. The gateway explicitly sets up the query
classifier (i.e. chooses which one to use and what arguments to
provide), but the actual initialization is performed as part of
the general module initialization.
