调研方向
Start by running t/storable.t from MLDBM-2.05 on both PerlOnJava backends and compare the three failures with standard Perl. Then trace the PerlOnJava Storable freeze/thaw entry points used by MLDBM's portable serializer. Done means the upstream suite passes and focused regression coverage verifies scalar, shared, and circular references without changing standard freeze/thaw behavior.

描述
Summary
MLDBM-2.05 fails under PerlOnJava because the bundled Storable implementation loses values when MLDBM switches to portable serialization.
Reproduction
The upstream test t/storable.t uses:
use MLDBM qw(SDBM_File Storable);
...
$obj->DumpMeth('portable');
...
my $d = [17];
$o{g} = $d;
$d = '';
is($o{g}->[0], 17);
PerlOnJava returns undef instead of 17 for the final assertion. The same test also fails the circular/reference comparison assertions at lines 28 and 54.
Evidence
- Distribution:
MLDBM-2.05 - CPAN random tester run:
20260921-102914-97159 - Failing test:
t/storable.t - Standard Perl: PASS, 5 test programs and 19 tests
- PerlOnJava JVM backend: FAIL, 3 of 9 tests in
t/storable.t - PerlOnJava interpreter backend: FAIL, identically, 3 of 9 tests
- The target distribution is pure Perl; this is not an XS/native dependency failure.
Expected behavior
PerlOnJava's Storable::freeze/thaw implementation should preserve circular references, shared references, and scalar values when used as MLDBM's portable serializer.
Acceptance criteria
MLDBM-2.05passes the complete upstream suite on both PerlOnJava backends.t/storable.tpasses the circular/shared-reference comparisons and the final scalar retrieval assertion.- Add focused project-owned regression coverage for portable Storable serialization through MLDBM, including a value whose source reference is subsequently changed.
