Add direct mode to Worker::execute()
...
Sometimes that's what you want, but primarily for completeness'
sake and it makes AUTO more sensical as it essentially chooses
beteen DIRECT and QUEUED mode.

Store error status into QueryResult object
...
The QueryResult-object remembers if a conversion failed. This makes checking
for errors more convenient, as just one check per row is required. The conversion
functions always return a valid value.

MXS-2208 Implement synchronous GET in terms of asynch
2018-12-18 15:16:45 +02:00
847f53b21b
MXS-2208 Introduce asynchronous GET
...
A multi HTTP GET can now be performed so that the caller
drives the polling of results.
This can now be used so that inside a monitor worker, the delays
are handled using delayed calls. Consequently, the monitor worker
event loop can remain responsive even though the Clustrix nodes
are being polled.

MXS-2196: Don't force epoll flags
...
The epoll event flags are now fully controlled by the caller of the
Worker::add_fd function. This makes the mechanism more generic and allows
both edge triggered and level triggered behavior.

MXS-2160 Use CLOCK_MONOTONIC_COARSE

We measure time in milliseconds and as CLOCK_MONOTONIC_COARSE
provides 1ms granularity we should use that since it is cheaper.

MXS-2057 Do not require systemd libraries
...
Exclude systemd usage if the library is not installed.
Only excluding what is necessary. This keeps the object size the
same and still compiles most of the code.

MXS-2057 systemd watchdog
...
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.

MXS-2137 Remove meaningsless statistics
...
The removed statistics variables have no meaning anymore and
were not updated.
Decided to simply drop the variable from the JSON output. It
gets far too rigid if fields of objects cannot be changed without
bumping the REST-API version.
