ed80680da9 MXS-2304 Add ctor/dtor and other functions to parameter class
The manipulation functions are currently static so that the container can be initialized
if required. This will be fixed later.

The new functions are taken into use in monitor management.

934be45b68 MXS-2304 Remove config_get_string() and config_get_value_string()
Some functions accessing internal pointers still remain.
2019-02-06 12:58:59 +02:00
4b2c0b3edd MXS-2304 Cleanup server_alloc()
Avoids using config_get_string().
2019-02-06 12:36:23 +02:00
78d9ef2910 MXS-2304 Remove remaining uses of config_get_string() from module code
The function returns a pointer to an internal string and should not be
used.
2019-02-06 12:36:23 +02:00
5ab7734e9d MXS-2304 Add contains() to test if a parameter exists
Replaces uses of config_get_param() in modules either with contains()
or get_string(). The config_get_param() is moved to internal headers,
as it allows seeing inside a config setting.

cf4724d128 MXS-2265: Fix formatting of the zero timestamp
The UNIX timestamp 0 should be treated as a special value and must be
interpreted as 0-00-00 00:00:00 instead of 1970-01-01 00:00:00.
2019-02-06 12:11:06 +02:00

08dd55a26a Use -ftls-model=initial-exec with maxscale-common
Resolving the relocations right at startup reduces the cost of using
thread-local variables.

f2d2202ea3 MXS-2304 Use get_enum() instead of config_get_enum() 2019-02-01 10:29:24 +02:00

63b5eab89e MXS-2304 Convert configuration management structs to classes
The fields of MXS_CONFIG_PARAMETER remain unchanged so that parameter
processing can be changed gradually.

03411e825d MXS-2271 Move journal_max_age inside settings container 2019-01-31 17:05:35 +02:00
ce9b49d8d5 MXS-2271 Move script-related settings to the settings-container
Also moves related functions to class methods.
2019-01-31 17:05:34 +02:00
0903648542 MXS-2271 Move connection settings inside settings struct
Since the settings are now protected fields, all related functions were
moved inside the monitor class. mon_ping_or_connect_to_db() is now a method
of MXS_MONITORED_SERVER. The connection settings class is defined inside the
server since that is the class actually using the settings.

3f4c72d4f2 MXS-2303: Fix missing parameter error
The detection of missing parameters that define which module to load must
be done before the module is loaded.

24c9b62a2f Add verbose logging for session command failures
If the routing of a session command fails due to problems with the backend
connections, a more verbose error message is logged. The added status
information in the Backend class makes tracking the original cause of the
problem a lot easier due to knowing where, when and why the connection was
closed.

2019-01-30 12:16:57 +02:00
bc4a52acb0 MXS-2273 Set SERVER_BEING_DRAINED properly

mechanism.
2019-01-30 12:16:57 +02:00
e3d74bd18d MXS-2273 Generalise names
The maintenance flag and being-drain flags will be turned on using
the same variable, so the variable and constant names needs to be
generalized.
2019-01-30 12:16:57 +02:00
159d9ccba9 MXS-2273 Move constants to more appropriate locations
Constants now used in the context of MXS_MONITORED_SERVER or
Monitor are now moved from SERVER to MXS_MONITORED_SERVER or
Monitor, respectively.
2019-01-30 12:16:57 +02:00
57a94b417d MXS-2273 Move maint_request from SERVER to MXS_MONITORED_SERVER
The _request_ for setting the status of a server relates to the
monitor and its MXS_MONITORED_SERVER, not to the SERVER itself.
2019-01-30 12:16:57 +02:00
727d3feb3b MXS-2273 Move code for setting maintenance bit to monitor.cc
Applies to being-drained as well.

Better that this special handling is handled by Monitor that needs it.
2019-01-30 12:16:57 +02:00
a205c70374 MXS-2273 Allow the setting and clearing of BEING_DRAINED bit
Currently the bit is set so that is may be overwritten by the monitor
if the setting of the bit takes place while the monitor is performing
its monitor loop.

16fc920d33 MXS-2299: Hints always take precedence
Hints should override all statement level routing decisions that would
otherwise be done based on the query type.

cef4e836bc MXS-2271 Store monitored servers in a vector
The array is still a public member because it's used in several non-member functions.

9083ea2d02 MXS-2290 Reject use of whitespace in section names
Whitespace in section names was deprecated in 2.2 and in 2.4 it
will be rejected.

0fe5b0bec9 MXS-2276 Expose lower level mon_ping_or_connect_to_db
The functionality is useful also when you do not have a
MXS_MONITORED_SERVER instance.

7d92717b66 MXS-2274 Prevent dynamic creation of object with invalid name
Unfortunately there is not a single place where the name could be
validated, but it has to be done separately for each object type.
2019-01-24 17:42:29 +02:00
5afceb1185 MXS-2274 Reserve names starting with @@ for use by MaxScale
Names starting with '@@' can now longer be used in configuration files.
Subsequent commits will prevent such names from being used when objects
are created dynamically.

3321a591ef MXS-2271 Move some monitor management functions to an internal class
The class MonitorManager contains monitor-related functions that should not
be called from modules. MonitorManager can access private fields and methods
of the monitor.

iterator was always returned.

7f978f275f MXS-2223 Log a message when a slave is discriminated due to replication lag
Both the replication lag and the message printing state are saved in SERVER,
although the values are mostly used by readwritesplit. A log message is printed
both when a server goes over the limit and when it comes back below.
Because of concurrency issues, a message may be printed multiple times before
different threads detect the new message state.

Documentation updated to explain the change.
