研究方向
Start with PerlOnJava’s bundled Hash::Util and its Hash::Util::FieldHash implementation; the issue identifies these APIs as the affected code. Run the reproducer on the JVM and interpreter backends, then check the project’s fieldhash tests and the Hash-ExtendedKeys 1.01 suite. Done means export succeeds, scalar keys work alongside reference keys, and the requested suites pass on both backends and system Perl.

描述
Summary
PerlOnJava's bundled Hash::Util omits the core fieldhash export, so CPAN module Hash::ExtendedKeys cannot load. After restoring the export, its tests also expose that the bundled fieldhash tie rejects ordinary scalar keys; core Perl treats those as regular hash entries.
Reproducer
use Hash::Util qw(fieldhash);
fieldhash my %fields;
$fields{plain_key} = 'value';
Expected: the import succeeds; ordinary scalar keys behave like normal hash entries, and reference keys retain identity-based fieldhash behavior.
PerlOnJava JVM and interpreter: before the export fix, compilation stops with "fieldhash" is not exported by the Hash::Util module. With the export restored but before scalar-key support, Hash-ExtendedKeys tests fail with Hash::Util::FieldHash keys must be references.
CPAN evidence
- Distribution:
Hash-ExtendedKeys1.01 - CPAN random tester run:
20261027-085020-3852 - Original failing test:
t/00-load.t; import aborts before the suite proceeds - System Perl 5.42.2: complete unchanged upstream suite passes (7 files, 24 tests)
- PerlOnJava Perl 5.044001: import failure reproduced on both JVM and interpreter backends; additional fieldhash behavior gap exposed on JVM
The failure was observed on macOS 26. The affected APIs are implemented by PerlOnJava's bundled modules. This is distinct from #1379, which fixed Hash::Util::FieldHash's :all export tag.
Acceptance
- Export
fieldhashfromHash::Utilwith behavior compatible with core Perl'sHash::Util::FieldHash. - Preserve ordinary scalar-key operations alongside reference-key fieldhash behavior.
- Add project-owned coverage validated on system Perl and both PerlOnJava backends.
- Confirm
Hash-ExtendedKeys1.01 loads and its unchanged suite passes.
