Summary | 0000792: pfsetvlan warning at line 999 | |||||||
Description | The error:Use of uninitialized value in string ne at /usr/local/pf/sbin/pfsetvlan line 999 (0000001) (W uninitialized) An undefined value was used as if it were already defined. It was interpreted as a "" or a 0, but maybe it was a mistake. To suppress this warning assign a defined value to your variables. To help you figure out what was undefined, perl tells you what operation you used the undefined value in. Note, however, that perl optimizes your program and the operation displayed in the warning may not necessarily appear literally in your program. For example, "that $foo" is usually optimized into "that " . $foo, and the warning will refer to the concatenation (.) operator, even though there is no . in your program. the code: if ( (@locationlog) && ( scalar(@locationlog) > 0 ) && ( $locationlog[0]->{'mac'} ne '' ) ) { if ($switch->isMacInAddressTableAtIfIndex( $mac, $switch_port ) ) { When locationlog has a NULL mac, the two first conditions are true but the mac field of $locationlog[0] is undef. The warning is about comparing undef with other stuff. Why does locationlog contains a NULL mac? Is it useful? I noticed that if $mac is undef in locationlog_insert_start then it will insert a NULL value for the mac. So its kind of supported.. I need to talk with Regis about that bug. Could this be the crasher we are looking for in some of our clients? | |||||||

I confirmed that it is not a crasher but it scares the users so I'll try to fix it. We need another condition in there that says defined($locationlog[0]->{'mac'}) |
