If normal authentication fails and a PAM service is defined, PAM authentication
is attempted. Separate services can be set for read-only users and admin-level
users.
Increasing counter sizes from int to long for averages.
Rename random functions to end with _co instead of _exclusive to
indicate range [close, open[, and to allow future suffixes oc, cc and oo.
Previously, runtime monitor modifications could directly alter monitor fields,
which could leave the text-form parameters and reality out-of-sync. Also,
the configure-function was not called for the entire monitor-object, only the
module-implementation.
Now, all modifications go through the overridden configure-function, which calls the
base-class function. As most configuration changes are given in text-form, this
removes the need for specific setters. The only exceptions are the server add/remove
operations, which must modify the text-form serverlist.
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.
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.
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.
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.
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.
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.
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.
Created the <maxbase/format.hh> header that contains various helper
functions for formatting values into human readable forms. Currently only
binary to human readable size conversion is implemented.
Clean up, comments and enhancements. StopWatch lap() didn't mean lap-time, but elapsed time. Changed meaning to lap-time and added split() for split-time.
