Actually with more reading on this getting the uncompressed size reliably can be a real pain, and thus is not in the getHeaderInfo over certain size lmits.
This approach may work for you is the compressed data is actually in a scalar and not too large. And not too small. YMMV.
my $z = read_file "product.json.gz"; my $io = IO::Scalar->new( \$z ); $io->seek( -4, 2 ); $io->read( my $buf, 4); my $uncompressed_size = unpack( 'V', $buf );
