I've been unsuccessful in trying to use the queue table type with the
Sleepycat:b interface and I cannot figure out why.

===
use Sleepycat:b;

my $db = new Db();
$db->open(undef, "test.db", undef, Db:B_QUEUE, Db:B_CREATE);

my($k, $v) = ('', 'test value');

$db->put($k, $v, Db:B_APPEND);
===
results in:
Db::_put() -- txnid is not an object reference at (eval 2) line 13,
<DATA> line 345.

(transactions aren't configured, obviously)

No luck _with_ transactions either:
===
use Sleepycat:b;

eval {
my $env = new DbEnv;
$env->open('testenv',
Db:B_CREATE|Db:B_INIT_MPOOL|Db:B_INIT_TXN|Db :B_INIT_LOCK,
0666);

my $db = new Db($env);
$db->open(undef, "test.db", undef, Db:B_QUEUE,
Db:B_CREATE|Db:B_AUTO_COMMIT);

my($k, $v) = ('', 'test value');

my $txn = $env->txn_begin;
$db->put($txn, $k, $v, Db:B_APPEND);
$txn->commit;
};
if($@) {
print $@->what, "\n";
}
===
Db:ut: Invalid argument in test_queue_txn, line 18

I've tried a number of other ways with much the same result. Does
anyone know if queues are just not supported by Sleepycat:b?
