You can find data from a test run of the "CPAN-river-top-1000" against perl-5.27.11 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 2017. What is essentially the same data is presented in a slightly different format here: http://thenceforward.net/perl/misc/xformat-cpan-river-1000-perl-CPAN-river-1000: failures as of perl-5.27.105.27-master.psv.gz The attachment, 'changes-5.27.10-to-5.27.11.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 5.27.10 and 5.27.11; or (b) received a grade other than 'PASS' in 5.27.11. A large number of the distributions listed in changes-5.27.10-to-5.27.11.csv have an 'x' in the final column, meaning that when I ran my test-against-dev program earlier this morning, 'cpanm' bailed out before being able to test that distribution. That generally happens when an upstream prerequisite has a build or test failure, fails to install, and causes 'cpanm' to bail when it comes to the prerequisite's reverse dependency. (If I were using 'cpan' rather than 'cpanm', this would be logged as a DISCARD in the .cpanreporter/reports-sent.db file; thanks to Slaven for calling my attention to that.) This month, many of those 'x' distributions were affected by problems with File-Copy-Recursive. Version 0.41 of that distribution was released two days ago, but failed to specify one dependency. The author has subsequently corrected that omission and has issued version 0.42 -- but that didn't take place until after my test-against-dev program had run. Many distributions in the CPAN river top 1000 are dependent on File-Copy-Recursive, so they were not reached when test-against-dev ran. Now that FCR 0.42 has been released, I'm going to retry the distributions that were graded 'x'. Some of the distributions in changes-5.27.10-to-5.27.11.csv are previously known failures. Dave Mitchell surveyed these on this list last month: https://www.nntp.perl.org/group/perl.perl5.porters/2018/03/msg250135.html Anyone who wishes to follow up on this data or help me further develop analyses like this should contact me. This will be the final report of this data in the 5.27.* development cycle. I hope to begin anew, covering a larger subset of the CPAN river, once 5.29.0 is released. Thank you very much.
