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.
The stacktrace now removes leading paths from object files and common
source code prefixes. It also skips the first five frames which are always
inside the stacktrace printing code and the signal handler.
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.
log.cc:this_unit.slogger depends upon logger.cc:this_unit.ident.
Depending on which one is destructed first, there will be a crash
or then not.
It seems that the destruction order when returning from main()
is not necessarily the same as that when calling exit() in main,
as this bug is triggered with compilers versions and not with other.
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.
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.
