# New Ticket Created by James E Keenan # Please include the string: [perl #119351] # in the subject line of all future correspondence about this issue. # <URL: https://rt.perl.org:443/rt3/Ticket/Display.html?id=119351 > At some point between Perl 5.18.0 and 5.18.1, Devel::Cover began to fail most of its tests. Here are the CPAN Testers Perl/Platform version matrices for Devel::Cover 1.06 and those two versions of Perl: http://matrix.cpantesters.org/?dist=Devel-Cover%201.06;perl=5.18.0;reports=1 http://matrix.cpantesters.org/?dist=Devel-Cover%201.06;perl=5.18.1;reports=1 With one unusual exception, D::C 1.06 has built and tested successfully on Perl 5.18.0. In addition to the platforms listed there, yesterday I successfully built, tested and installed D::C 1.06 on Perl 5.18.0 on the same Darwin/PPC machine on which I have installed D::C for many years. (I had not yet upgraded to Perl 5.18.1 on that machine.) However, when we turn to the matrix for Perl 5.18.1, we see D::C failing across the board. I haven't inspected all the failure reports, but for those I have I observe: * They are the same failures I got yesterday when trying to install D::C 1.06 on top of a new Perl 5.18.1 on the same Linode (i686) on which I have installed both Perl and D::C for many years. * They are the same failures seen in the one, unusual failure report for 5.18.0 noted above (http://www.cpantesters.org/cpan/report/792ad9d4-04b5-11e3-b7c0-ec8abfc46414). When diagnosing this yesterday, I tried to install a slightly older version of D::C (1.02) on Perl 5.18.1 on the Linode. I know that this version worked with Perl 5.18.0 because I had installed it there earlier (but I had to remove the 5.18.0 for other reasons). D::C 1.02 failed on 5.18.1 just as D::C 1.06 does. So I inferred that the problem lies in changes to Perl rather than changes to Devel::Cover. This has been reported in D-C's bug queue: https://github.com/pjcj/Devel--Cover/issues/66 In that report, the poster notes what I also observed: On top of 5.18.1, none of the cover_db/ databases are being written to. This would explain why, in the individual failure reports, the "Got" (left-hand) side of the output chart shows blanks where the "Expected" (right-hand) side of the chart shows coverage percentages. Can someone with a big enough box try at a 'git bisect' on this? Thank you very much. Jim KeenanThread Next
