Zlib compression broken

Zlib compression is broken. This means large payloads are never compressed on the network.

class Compression extends CouchbaseTestCommon {
function testCompression() {

if (!extension_loaded('zlib'))

{ $this->markTestSkipped("Need Zlib extension"); }

$h = make_handle();
$hnc = make_handle();

$curcomp = couchbase_get_option($h, COUCHBASE_OPT_COMPRESSION);
$this->assertEquals(COUCHBASE::COMPRESSION_NONE, $curcomp);

couchbase_set_option($h, COUCHBASE_OPT_COMPRESSION,
COUCHBASE::COMPRESSION_ZLIB);
$curcomp = couchbase_get_option($h, COUCHBASE_OPT_COMPRESSION);
$this->assertEquals(COUCHBASE_COMPRESSION_ZLIB, $curcomp);

couchbase_set_option($hnc, COUCHBASE_OPT_COMPRESSION,
COUCHBASE::COMPRESSION_NONE);

$inikey = "couchbase.compression_threshold";
$this->assertGreaterThan(0, ini_get($inikey));
$this->assertTrue((bool)ini_alter($inikey,"10"));
$this->assertEquals(10, ini_get($inikey));

1. Set a compressed value
   $v = str_repeat("long_value", 500);
   $ol = strlen($v);
   //$key = $this->mk_key();
   $key = "compressed_data";

$rv = couchbase_set($h, $key, $v);
$this->assertNotEmpty($rv);

$comp = couchbase_get_option($h, COUCHBASE_OPT_COMPRESSION);
print $comp . "\n";

1. Hack, append resets the flags, clearing the compression state.
   $rv = couchbase_append($hnc, $key, '_');
   $this->assertNotEmpty($rv);

$ret = couchbase_get($hnc, $key);
$this->assertNotNull($ret);
$this->assertLessThan($ol, strlen($ret));
}
}
