Línea de trabajo

Start by reproducing the minimal SQLite INSERT and inspect the bundled DBI compatibility layer that updates errstr after successful operations. Then run t/20-register_application.t, the t/30-Application tests, and t/35-get_application.t; done means successful operations leave errstr undefined and these failures pass under both backends.

Summary

IPC::Concurrency::DBI v1.2.0 fails under PerlOnJava even though its upstream suite passes under system Perl.

Evidence

  • CPAN run: 20260928-091741-26386
  • Distribution: IPC-Concurrency-DBI v1.2.0
  • System Perl: 22 test files, 103/103 tests passed.
  • PerlOnJava: 12/22 test programs failed and 13/78 subtests failed.
  • The failures occur in t/20-register_application.t, the t/30-Application/... tests, and t/35-get_application.t.
  • Both JVM and interpreter backends reproduce the issue.

The first successful SQLite INSERT returns one affected row, but PerlOnJava reports defined($dbh->errstr) == 1 with an empty string. System Perl reports defined($dbh->errstr) == 0 after the same successful operation. IPC::Concurrency::DBI checks whether errstr is defined and therefore turns successful SQL operations into Cannot execute SQL: failures.

Minimal behavior:

my $rows = $dbh->do(
  'INSERT INTO t(name,n) VALUES (?,0)', {}, 'x'
);
# PerlOnJava: rows=1, errstr defined, errstr=""
# System Perl: rows=1, errstr undef

This points to the bundled DBI compatibility layer clearing errstr to an empty defined scalar instead of undef after success.

Dependency note

PerlOnJava uses its bundled Perl/JDBC DBI + SQLite implementation, so this is an internal DBI compatibility issue rather than an unsupported native prerequisite. A targeted DBD::SQLite reverse-dependency lookup was attempted for classification but MetaCPAN was unavailable; no dependency count is inferred.
