| Subject: | Change in Perl default @INC breaks tests |
***WARNING***
A recent security patch to Perl itself removed '.', the current working
directory, from @INC, the default search path for 'use', 'do', and
'require'. This fix for CVE-2016-1238 will be part of Perl 5.26.0, due
to be released this April, 2017. CPAN.pm will *temporarily* provide
backwards compatibility during the module build/test/install process
by setting the environment variable PERL_USE_UNSAFE_INC=1 during build,
test, and install. HOWEVER:
1) This environment variable is a temporary fix only for compatibility,
due to be removed for Perl 5.30.0.
2) This may mask errors in your module itself, by testing your module
under different conditions than those that it will actually be run
under.
