Aerospike php8 client return null if data inserted through old client

[piyush-bansal1989]

Hi Team

I'm encountering a data discrepancy with a new client. Data saved through the old client isn't being retrieved correctly by the new client. Specifically, the new client returns a null value for the key (Primary Key), where the old client successfully stores a value.

I also found some data save format discrepancy in old have found format like below. In new client data saving as json string.

Hi, could you clarify what you mean by the "old client"? An older release of the current PHP 8 compatible version (that we have recently released), or the older C-based version of the client?

The C-based version which supports till php7

Could you please share a code snippet that reproduces the issue (in both the new and old client code)?

Regarding the key value, are you setting the WritePolicy.SendKey to true when writing the key to the database?

Below are the code snippets for both clients
Old php7 client sample code
`<?php
//use Aerospike;
class Testing{
public $a;
public $b;
public $c;
}

$t = new Testing();
$t->a = 4;
$t->b = 5;

$config = [];

$config['hosts'][0] =[
'addr' => "%SERVER_ADDRESS%",
'port' => (int) 3000
];

$options = [
Aerospike::OPT_POLICY_KEY => Aerospike::POLICY_KEY_SEND,
Aerospike::OPT_CONNECT_TIMEOUT => 5000,
Aerospike::OPT_READ_TIMEOUT => 5000,
Aerospike::OPT_WRITE_TIMEOUT => 5000,
Aerospike::OPT_MAX_RETRIES => 3,
Aerospike::OPT_SLEEP_BETWEEN_RETRIES => 2000
];
$aerospike = new Aerospike($config, true,$options);
$key = $aerospike->initKey("namespace", "test", "testing");
$content = array(
"testing" => $t
);
$bins = [
'content' => $content
];
$response = $aerospike->put($key, $bins, 0, []);
if ($response == Aerospike::OK){
echo "data saved in aerospike \n";
}
$record = [];
$getResponse = $aerospike->get($key, $record, null, []);
if ($getResponse == Aerospike::OK){
echo "Get response from Aerospike \n";
print_r($record);
}`

New Client php8 sample code
`<?php

namespace Aerospike;

$socket = "/var/www/html/asld_grpc.sock";
$client = Client::connect($socket);
$key = initKey("namespace", "test", "testing");
$rp = new ReadPolicy();
$rp->setMaxRetries(3);
$rp->setSocketTimeout(5000);
$record = $client->get($rp, $key);

print_r($record);

function initKey($ns, $set, $key){
return new Key($ns, $set, $key);
}
`

Regarding the key value, are you setting the WritePolicy.SendKey to true when writing the key to the database?

No. I'll try and let you know

@khaf / @vmsachin : can you please provide some update ?

@piyush-bansal1989 Sorry for the late reply. Using the latest PHP client, I cannot reproduce the key issue. The original key value is stored and returned by the client. There is a bug in converting long values in the connection manager that we will address in the release next week.
Regarding the object retrieval, the old PHP client would automatically serialize and unserialize PHP objects into blobs. The new client does not do that, so you should do it manually yourself.
The byte array you have pasted is incomplete (missing a few bytes at the end), but if it was complete and you passed it to the unserialize function, you would get your object back.

@piyush-bansal1989 Here is the code I used to do it:

$bytes = [0x4F, 0x3A, 0x32, 0x39, 0x3A, 0x22, 0x43, 0x6F, 0x6D, 0x70, 0x6F, 0x6E, 0x65, 0x6E, 0x74, 0x73, 0x5C, 0x54, 0x69, 0x6F, 0x5C, 0x54, 0x65, 0x73, 0x74, 0x44, 0x65, 0x74, 0x61, 0x69, 0x6C, 0x73, 0x54, 0x69, 0x6F, 0x22, 0x3A, 0x35, 0x30, 0x3A, 0x7B, 0x73, 0x3A, 0x37, 0x3A, 0x22, 0x61, 0x6D, 0x63, 0x61, 0x74, 0x49, 0x64, 0x22, 0x3B, 0x73, 0x3A, 0x31, 0x34, 0x3A, 0x22, 0x31, 0x31, 0x32, 0x36, 0x30, 0x30, 0x30, 0x35, 0x32, 0x35, 0x33, 0x36, 0x30, 0x35, 0x22, 0x3B, 0x73, 0x3A, 0x36, 0x3A, 0x22, 0x74, 0x65, 0x73];

$s = pack('C*', ...$bytes);
$object = unserialize($s);

You can of course use serialize to convert the object to a string and then later to a byte array:

$s = serialize($object);
