----------------------------------------------------------------
I explain some of them:
2). Hung when work throw thrift framed transport
In PHPOutputTransport destructor you make flush(), but in
PHP_FUNCTION(thrift_protocol_write_binary) you make flash too at the end:
transport.flush(), in framed transport this call hung
3). Memleak in protocol_writeMessageBegin
In this function you allocate 3 function agrs (MAKE_STD_ZVAL), but doesn't free
them with zval_ptr_dtor. On very long executed scripts this results as
Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate
30084 bytes)
How fast you got this error, depends on your memory_limit config param in php
4). Hung when server close connection, and when php code try reuse same
connection
To reproduce:
{code}
<?php
define("LIBPATH", "lib/");
require_once("thrift/Thrift.php");
require_once("thrift/transport/TSocket.php");
require_once("thrift/transport/TFramedTransport.php");
require_once("thrift/protocol/TBinaryProtocol.php");
require_once('Log.php');
require_once('Log/file.php');
require_once(LIBPATH."cassandra/Cassandra.php");
require_once(LIBPATH."cassandra/cassandra_types.php");
$transport = new TFramedTransport(new TSocket("localhost", 9160));
$protocol = new TBinaryProtocolAccelerated($transport);
$client = new CassandraClient($protocol);
$transport->open();
$client->set_keyspace("test");
$l_supercolumn = new cassandra_SuperColumn(array("name" => '12', "columns" =>
NULL));
$l_c_or_sc = new cassandra_ColumnOrSuperColumn(array("super_column" =>
$l_supercolumn));
$l_mutation = new cassandra_Mutation(array("column_or_supercolumn" =>
$l_c_or_sc));
for($i=0; $i < 10; $i++)
{
try
{
$client->batch_mutate(array('1' => array('test' =>
array($l_mutation))), cassandra_ConsistencyLevel::QUORUM);
}
catch(Exception $e)
{
print $e;
print "\n\n";
};
};
sleep(30);
?>
{code}
This code when fist time got to batch_mutate, will throw TApplication
exception, second attempt will hung in TSocket::readAll, because fread will
always return empty data
5). Impossible pass really long values on 32 bit platforms
Try to pass something like this: 4294967296 on 32 bit platform and look what
you get on server. Result will surprise you
