The bugzilla install is very old now (4.0.1) and although it would be best, upgrading is a real pain as I suck at Perl related stuff. It has worked with no issue for many years and stopped in December. On checking the serverhost changed to Perl 5.16.3. Originally it was 5.8.8 and even after 15.10 it worked fine.
The issue I get is very similar to this issue - Bugzilla: bugs are not showing up (show up in DB and everything seems to be fine) But it is not a template or character problem (the site ran fine with no changes) that I can see and happened the same week the host updated Perl , so I am 99% sure it is Perl related. I am assuming the issue is with either buglist.cgi itself or search pm. Any time I browse or search the Product, component, resolution etc shows "ARRAY and a number. e.g. Product: ARRAY(0x30090f0) Component: ARRAY(0x3993420) Resolution: ARRAY(0x3993378).
The bugzilla is only accessible internally (but hosted by a third-party, so no admin) it only allows user accounts access to search and browse so I cannot demo the issue. Is there a known depreciated Perl command?
Would love to fix but may have to install a new version and import DB, last time it took a few weeks to get running hence looking to avoid that for now.
I had the exact same issue. After digging a little figured this is an issue with the Perl version. In Search.pm,
$params->param("field$chart-$row-$col", shift(@$ref));this line is causing the issue. With 5.8.8 its returning Array object, whereas with 5.16.3 it is returning SCALAR.My option is to install 5.8.8 and re-install the compatible modules. Or, is there any quick workaround for this?
Update:
Going through the docs, figured that 4.0.10 version of bugzilla has added support for Perl 5.16. Copied the CGI.pm from that and tested.. bugzilla is working. This is a bad hack. But, at least now I know that upgrading to 4.0.10 is another viable solution instead of upgrading Perl.
