Andy Kurth created VCL-865:
------------------------------
Summary: Remove all calls to defined(@array)
Key: VCL-865
URL: https://issues.apache.org/jira/browse/VCL-865
Project: VCL
Issue Type: Improvement
Components: vcld (backend)
Affects Versions: 2.4.2
Reporter: Andy Kurth
Priority: Minor
The backend code includes a few calls in the form:
{noformat}
if (defined(@array)) {
...
}
{noformat}
This causes a warning to be generated with newer versions of Perl:
{noformat}
defined(@array) is deprecated at
/usr/local/vcl/bin/../lib/VCL/Module/Provisioning/xCAT.pm line 694 (#1)
(D deprecated) defined() is not usually useful on arrays because it
checks for an undefined scalar value. If you want to see if the
array is empty, just use if (@array) { # not empty } for example.
{noformat}
All of these should be updated. I know there are calls in {{xCAT.pm}} and
{{vbox.pm}}.
