db_clean_hostname and HOSTNAME

Anonymous — Tue, 10 Oct 2006 22:53:56 -0000

On both Freebsd 6.1 and Debian...

When db clustering is enabled, all hosts attempt to
perform DB cleaning even though a short hostname is set
in sqlgrey.conf and it doesn't match the actual
hostname of the host.

upon investigation, this section of code seems to be at
fault. On my Systems, it leaves the $HOSTNAME variable
undefined.

>>>>> start code snippet <<<<<<

my $HOSTNAME;
eval { require Sys::Hostname; };
if ($@) { $HOSTNAME = hostname();}

>>>>> end code snippet <<<<<<

Doesn't properly define $HOSTNAME and because of that,
the following section of code below always returns a
"0" Which leaves the cleaning enabled for that this host.

>>>>> start code snippet <<<<<<

if ((defined $HOSTNAME) && (defined
$dflt{db_cleanup_hostname})) {

if ($HOSTNAME eq
$dflt{db_cleanup_hostname}) {
$dflt{dont_db_clean} = 0;
} else {
$dflt{dont_db_clean} = 1;
}

} else {
$dflt{dont_db_clean} = 0;
}
}
>>>>> end code snippet <<<<<<

I used the following to make this feature work
properly. But you might be able to come up with
something more to your liking that will work... or list
the required version of Sys::Hostname.

my $HOSTNAME;
use Sys::Hostname;
$HOSTNAME = hostname();

and I used the FQDN hostname for db_cleanup_hostname
variable in sqlgrey.conf
