Direzione di ricerca

Start with the existing PadWalker regression coverage for peek_our(0) inside a subroutine and trace how the JVM backend handles that lookup; the issue does not name the relevant files. Add project-owned top-level coverage for both JVM and interpreter backends, checking the expected variable names and references against system Perl. Run the regression tests and the Test::Expander upstream suite; done means the exports load and the suite proceeds.

Descrizione

area:backend bug

Summary

After adding the bundled Scalar::Readonly support for #1664, jcpan -t Test::Expander 2.7.1 gets past the missing XS implementation but all 26 test programs fail while loading Test::Expander::Constants. The module populates @EXPORT_OK from PadWalker::peek_our(0) at file scope; on the JVM that lookup does not return its package variables, so imports such as $COMMENT, %OPTION_PARSER, and %REST_CONSTANTS_TO_EXPORT are reported as not exported.

Reproduction

use PadWalker qw(peek_our);
our $probe = 17;
my $vars = peek_our(0);
print join(',', sort keys %$vars), "\n";

System Perl reports $probe; PerlOnJava's JVM reports an empty key list. The existing PadWalker regression covers peek_our(0) inside a subroutine, but not at file scope.

The affected upstream run used nice -n 19 timeout 1800 ./jcpan -t Test::Expander. It failed 26/26 programs before their tests could run, with “is not exported by Test::Expander::Constants” errors. This is a follow-up to #1664: the missing Scalar::Readonly XS support is now available, and this issue tracks the separate PadWalker::peek_our behavior needed by this consumer.

Expected behavior

PadWalker::peek_our(0) should expose package our variables at file scope with Perl-compatible names and references, so Test::Expander::Constants can build its export list and the upstream suite can proceed.

Regression coverage

Add project-owned coverage for top-level peek_our(0) on both JVM and interpreter backends, validate the oracle with system Perl, then rerun the Test::Expander upstream suite.
