I made some changes in a mod in cpan, P, and upgraded the test module as well.

During devel, and in the first 1.1.0 release I found 2 probs that I tried to check for at the beginning of the test. Problem 1 is if I have PERL5OPT set in my env with a -CSA.

First workaround was to try to unset it at the beginning of the test (ENV{PERL5OPT}=undef): No effect.

Next thing I tried was checking if it was defined and if so, printing an error to STDERR and dying, but in a compile in cpan just now, it didn't die on each test (which it should have if it checked for that value -- it only died on the one test that it affected:

#   Failed test 'test mixed digit string'
#   at t/P.t line 109.
# Looks like you failed 1 test of 27.
t/P.t .. 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/27 subtests

Compare that to what happens if I run make test:

I.e. most or all of the tests should fail.

2nd problem has to do with a needed pre-req, 'mem.pm'. While it is in my Makefile.PL, and ends up in the META files (my meta, yml, json..). Similar prob -- in that
1) it isn't pulling in the pre-req. So, in P.t (1.1.1), I
2) checked for it, tried to run cpan to install it if it was missing, and if it couldn't -- then die with fat error message like above -- same prob, it acts like it completely circumvents my check for the pre-req, but only sometimes! (somewhere along the line, a "use 5.12.0" got inserted in the test program (not sure how or why). So instead of this check code:

BEGIN{
  eval {require mem };
  if ($@ && $@ =~ /Can't locate mem/) {
    # attempt to install via cpan
    my $inst=`cpan -i mem`;
    $inst =~ /PASS/ || do {
    die "\n*****************************************\n".
         "*****************************************\n" .
         "*****************************************\n" .
         "*   Cannot install mem via cpan: BIGFAIL*\n".
         "*****************************************\n" .
         "*****************************************\n" .
         "*****************************************\n";
     };
  }
}

Say what? How can mem be missing and yet the PREREQ's claim it is loaded?

Not only did it not show the error, if it wasn't loaded, but it then claimed it WAS both "not found", yet loaded.

I dunno, but doesn't that violate causality or some quantum law or is that like the cat being both alive and not alive at the same time? ???

Very confused....
Linda, still diddling in perl...
