Gearman出现分割错误的工人

Question

运行我的工作者时出现错误：

Segmentation fault (core dumped)

尝试通过命令行为Gearman Client运行worker时出现分段错误。

此消息工作者在获得一些正确的响应后得到。

我的工作人员代码：

<?php
require __DIR__ . '/vendor/autoload.php';

use ClickHouseDB\Client;
use ClickHouseDB\Quote\FormatLine;

$config = [
    'host' => '',
    'port' => 0,
    'username' => '',
    'password' => ''
];
$db = new Client($config);
$db->database('mydb');  

$worker= new GearmanWorker();
$worker->addServer('127.0.0.1', '4730');
$worker->addFunction("send_to_clickhouse", "processing", $db);


while (1)
{
  $worker->work();
  if ($worker->returnCode() != GEARMAN_SUCCESS){
      echo "return_code: " . $gmworker->returnCode() . "\n";
      break;
  }
}

function processing($job, $db)
{
    $message =  $job->workload();
    $data = json_decode($message, true);
    $statement = $db->insert($data['table_name'], [array_values($data['columns'])], array_keys($data['columns']));
    $statement->error();
    echo $data['table_name']."\n";
}
?>

运行工人：

php worker.php

工作者输出：

table1
table2
Segmentation fault (core dumped)

我正在使用smi2/phpclickhouse扩展名将数据发送到数据库

命令dmesg返回：

如果我删除代码statement = $db->insert(...，似乎一切正常。

任何想法需要解决的问题吗？

Answer 1

我在运行PHP 7.2.24的Ubuntu 18.04 LTS中也遇到了这个问题。我发现这是gearman-php扩展中的错误（已为fixed）。

要解决这个问题，您需要下载，编译和安装gearman pecl模块

cd /tmp/
sudo wget https://github.com/wcgallego/pecl-gearman/archive/gearman-2.0.6.zip
unzip gearman-2.0.6.zip
cd pecl-gearman-gearman-2.0.6
sudo phpize
./configure
sudo make
sudo make install

要在Ubuntu上完整安装Gearman for PHP7，请参考此guide
