name_lookup() now returns all results given by getnameinfo(). When searching
for a server, finding one matching address in the lookup-results is enough for
a match.
Also, added a test for name_lookup(). The test is minimal on its own, as hardcoded
test cases are not generally valid.
When matching hostnames between MaxScale server configuration and the
SHOW SLAVE STATUS-output, use DNS-resolution if a simple string comparison
doesn't find an answer. Results of the resolution are saved to avoid
repeating the operation for the same address.
By having a separate FINISHED state and a STOPPED state, it is possible to
know at which point in the worker's lifetime an event is done. Posting of
messages before a worker is started is allowed but posting them after the
worker has stopped is not.
This fixes avrorouter related failures and all other failures that stem
from worker messages being ignored at startup.
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.
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 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.
