Systemd wathdog notification at a little more than 2/3 of the
systemd configured time. In the service config (maxscale.service)
add e.g. WatchdogSec=30s to set and enable the watchdog.
For building: install libsystemd-dev.
The next commit will modify cmake configuration and code to
conditionally compile the new code based on existence of libsystemd-dev.
This will simply cause a task to be posted to each worker.
If the workers are running normally, the task will reach the
workers and the associated semaphore posted, and the REST-API
call will return. If any worker is not running normally, the
task will not be processed and the REST-API call will hang.
The read-write distribution in readwritesplit is now stored in a map
partitioned by the servers that the router has used. Currently, the
statistics for removed servers aren't dropped so some filtering still
needs to be added.
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
By removing the constness of the type for the actual stored value, the
return values of the access operators are defined by the type itself. This
allows both const and non-const types to be stored in a rworker_local
object.
Given that worker.hh was public, it made sense to make routingworker.hh
public as well. This removes the need to include private headers in
modules and allows C++ constructs to be used in C++ code when previously
only the C API was available.
