while reading `update_server_addr_port` I found out some things which
can be seen as incoherency. I hope I did not overlooked anything:
- one comment is stating check's address should be updated if it uses
the server one; however the condition checks if `SRV_F_CHECKADDR` is
set; this flag is set when a check address is set; result is that we
override the check address where I was not expecting it. In fact we
don't need to update anything here as server addr is used when check
addr is not set.
- same goes for check agent addr
- for port, it is a bit different, we update the check port if it is
unset. This is harmless because we also use server port if check port
is unset. However it creates some incoherency before/after using this
command, as check port should stay unset througout the life of the
process unless it is is set by `set server check-port` command.
quite hard to locate the origin of this this issue but the function was
introduced in commit d458adcc52b74608e2fe6a2a95f09ce5e94932b7 ("MINOR:
new update_server_addr_port() function to change both server's ADDR and
service PORT"). I was however not able to determine whether this is due
to a change of behavior along the years. So this patch can potentially
be backported up to v1.8 but we must be careful while doing so, as the
code has changed a lot. That being said, the bug being not very
impacting I would be fine keeping it for 2.4 only.
