You may find data from a test run of the "CPAN-river-top-1000" against perl-5.27.8 here: http://thenceforward.net/perl/misc/cpan-river-1000-perl-5.27-master.psv.gz The file above presents the data in the same format which I used for 5.27.6 and 5.27.7 in November and December. What is essentially the same data is presented in a slightly different format here: http://thenceforward.net/perl/misc/xformat-cpan-river-1000-perl-5.27-master.psv.gz Reviewing the data from 5.27.0 through 5.27.8, I came to realize that certain CPAN distributions could fail to be reported on under certain conditions. See attachment 'moosex-getopt.psv', which extracts data for MooseX-Getopt from the first link above. Note that this distribution lacks data for the most recent release, 5.27.8. Why is that? Hold that question for a moment. Let's look at the second attachment, 'xformat-moosex-getopt.psv'. Here, rather than have the last four columns empty strings, we instead print a lower-case 'x' to those fields to improve readability. The reason why MooseX-Getopt lacks data for the most recent release is that one of its prerequisites, Getopt-Long-Descriptive, began to experience test failures against blead in the 5.27.7-to-5.27.8 development cycle. Once it failed to install, none of its reverse dependencies, including MooseX-Getopt could be attempted by 'cpanm', the installer used in gathering this data, or by App::cpanminus::reporter, the test reporting library in use. The third and fourth attachments, 'getopt-long-descriptive.psv' and 'xformat-getopt-long-descriptive.psv', add data for that distribution. The fifth attachment, 'changes-5.27.7-to-5.27.8.csv', presents another subset of the data set found at the second link above. It presents results from just the last two monthly releases for those distributions which either (a) had a change of grade between 5.27.7 and 5.27.8; or (b) received a grade other than 'PASS' in 5.27.8. Anyone who wishes to follow up on this data or help me further develop analyses like this should contact me. Thank you very much. Jim Keenan
