Local Packages

  • New package perl-PPIx-Utils (0.003)

  • Updated perl-Perl-MinimumVersion to 1.40:

    • Features enabled via the 'experimental' pragma are now recognized (GH#5)

    • Depend on PPIx::Utils instead of Perl::Critic::Utils (GH#6)

    • Recognize several new features and their minimum required Perl versions (GH#10, GH#20): 'say', 'smartmatch', 'postderef', 'postderef_qq', 'signatures', 'refaliasing', 'bitwise', 'declared_refs', 'isa', 'indirect'

  • Updated schily to 2021.04.21; I added this work-around for SIGSTKSZ not being a compile-time constant from glibc 2.34 onwards: 

  •    1 In glibc 2.34, SIGSTKSZ is not a compile-time constant

   3 A 64 KB signal stack should be ample on all platforms.
