Jorker

Run jobs with multi process. | 脚本多进程执行

Features

• Execute script with multi process. 脚本多进程执行
• Continue last job that last time stopped. 支持中断续运行
• Memory overload protection. 内存过载保护
• Timing report progress. 定时报告进度
• Highly configurable. 高度可配置

Fixme

• 已知问题：主进程中有数据库连接时，在子进程退出时会将连接析构，导致主进程中连接失效。

Setup

composer require jorker/jorker

Usage

<?php
  require_once(dirname(__DIR__) . '/vendor/autoload.php');

  $manager = new \Jorker\JobForker(3);
  $manager->allot(function() {
  
      // RETURN OR YIELD JOBS IN MASTER PROCESS...
      for($i = 0; $i < 100; $i++) {
          yield ['i' => $i];
      }
      
  })->run(function($job, \Jorker\Slave\Slave $slave) {
  
      // DO SOMETHING IN SUB PROCESS...
      $slave->logger()->info("use this way if you want print log {$job['i']}.");
      
  });

  @param int $limit | Sub process limit. 使用多少个子进程
  @param array $options | configs. 配置项
    [

      "slaveMaxMemory" => 256*1024*1024,      // Sub process max memory, if over this value, master will stop this sub process and fork a new one. 子进程最大内存，超出该内存终止子进程，终止后父进程会重新fork一个新的子进程
      "reportInterval" => 600,                // Execute report handler every {reportInterval} seconds. 运行指定秒数后，对运行时统计进行报告

      "stampFilePath" => "/tmp/stamp.dat",    // File path that save last job when user CTRL+C stopped script. 用于记录上一次中断时，即将执行数据的保存路径
