Summary

  • fix compiler/runtime semantics exposed by eight CPAN installation suites:
    subroutine rvalues, interpreter context, source UTF-8 octets, nested glob
    dereferences, inherited AutoSplit stubs, and byte-string AUTOLOAD names
  • complete IPv6 and UDP behavior across Socket, Socket6, Java NIO socket
    handling, and the Net-ext compatibility bridge
  • support generated jperl shebang commands in piped opens
  • add focused compatibility modules for XS-only dependencies
  • add regression coverage and an unreleased changelog section without changing
    the released v5.44 notes

Compiler/runtime fixes are used wherever possible. The only upstream test
patches are narrowly scoped skips for three fork-dependent
IO::Socket::INET6 tests and one obsolete Class::Trait warning assertion
that also fails under standard Perl.

Verification

  • make
  • make test-bundled-modules
  • ./jcpan -t HTML::Diff
  • ./jcpan -t Graph::PetriNet
  • ./jcpan -t MIME::Lite
  • ./jcpan -t File::Path::Tiny
  • ./jcpan -t Net::UDP
  • ./jcpan -t IO::Socket::INET6
  • ./jcpan -t Email::Sender
  • ./jcpan -t JSONP
  • focused new tests validated with standard Perl before PerlOnJava

All commands above pass locally. The IPv6 installation suite was run with
local socket access because its bind/listen coverage cannot run in the
restricted execution sandbox.

Fix compiler and runtime semantics exposed by HTML::Diff, Graph::PetriNet,
MIME::Lite, File::Path::Tiny, Net::UDP, IO::Socket::INET6, Email::Sender,
and JSONP. Add focused compatibility shims where XS or unsupported process
features require them, plus regression coverage and documentation.
