            }
        }

try{

if(!isset($instances)){

$dbo->isDebug = $this->isDebug();

$tools = new StatTools($dbo);

$ip = new StatIpLocation(__DIR__ . '/QQWry.Dat');

$region = new StatArea();

$instances = new StatLog($tools, $ip, $region);

}

$this->isDebug()

&& $this->log(var_export($data, true));

$instances->add($data);

} catch(Exception $e){

$this->log($e->getMessage());

$this->logError($e->getMessage());

// 清理资源，在swoole下特别注意，经常unset()不需要的变量

unset($instances);

if(isset($dbLink)){

$dbLink->close();

unset($dbLink);

}

在发生Exception后，static类型的变量instances未被unset

我的2016

2016年12月29日 by admin·已关闭评论

这一年又这样过了，这几天一直在准备，感觉不知从何开始，与往常一样，就这样平淡的度过了一年

这一年比较好的是有很多时间专门写代码的时间，进来个产品帮我做了大部分不是技术开发做的事，少了很多无效率的会议，产品设计等工作，在技术上：

详细测试、阅读了大量php开源项目，如Symfony, yii2, cphalcon, laravel等, 公司框架也借鉴了他们的设计思路与代码, 阅读并测试的开源组件twig, fastRoute, mongolog, doctrine2, php-debug, pimple, runkit等
完成公司框架组件化，原有框架功能臃肿，在这一年花了近两个月的时候拆分为20多个组件项目，独立维护
搭建公司composer私有源管理与维护
搭建公司git项目远程服务管理与维护
在swoole扩展的支持编写了php在网络通信服务公用组件，Tcp, http, yar等协议的服务
在包装的tcp, http, yar组件的基础上，实现了一个通用的Api组件，实现高效服务端Api接口
编写与整理的php代码超过12w行(包括注解在内, 不包含开源项目), 编写代码量应该超过了前三年的总和
githup发由了第一个开源项目 syar, 得到了swoole官方帮忙推广(感谢)
学习了go的基础语法及协程
尝试Vue.js在实际项目的应用, 了解了Vue-route, vuex
尝试学习了nodeJs, es6语法及基础包管理, 并尝试使用了webpack打包工具及各种Loader
平均每月2+技术博文(未达到年初计划)
了解并简单测试了docker

在工作上：

了解调研VR产品
搭建了公司各类分站(奇台、府河)
平台引入IM, 工单系统
调研了解并搭建完善微商务系统
参与开发了招商宝、销售宝系统
着手开发公司自己的IM系统
致力于组件化、模块化、服务化方面的尝试及相关的准备工作
rap接口文档的尝试

学习了以下书籍(部分书籍粗浅的、片断阅读)：

技术管理之道
从0到1
黑客与画家
软件设计师
自控力
Linux系统编程
phpunit-book电子书
Symfony_components_3电子书
Symfony_best_practices_3.0电子书
Symfony_book_3.0电子书
Symfony_cookbook_3.0电子书
Symfony_best_practices_3电子书
phalcon-php-framework电子书
Yii 2.0 权威指南
JavaScript高级程序设计电子书
其它

在生活上：严重不及格，很多计划都未实现

syar 基于swoole实现的Yar服务

2016年12月1日 by admin·已关闭评论

为何用swoole来实现 Yar server

提升Yar服务端执行效率
学习swoole, yar(在此感谢laruence,rango及swoole开发团队)

Requirements

php5.4+
ext-swoole 1.8.8+
ext-msgpack 如果yar使用msgpack编码方式

Installation

composer require stcer/syar

1	composer require stcer/syar

简单性能测试

测试脚本 example/benchmark.php, 测试环境(虚拟机)

cpu: i5 – 4460
mem: 4G
os: centos6.5
php: php7(fpm: 20进程, swoole: 18进程(8 worker + 10 task)

脚本一共完成44次接口调用：

简单接口调用 2次
数据库查询接口调用2次
并发简单接口调用 20次
并发数据库查询接口调用 20次

function test($type, $times = 5, $limit = 5){
    $timer = new Timer();
    $benchmark = new Benchmark($type);
    $rs[] = $benchmark-&gt;simpleTest(); // 2
    $rs[] = $benchmark-&gt;dbTest($limit); // 2
    $rs[] = $benchmark-&gt;batchTest($times, $limit); // 20
    $rs[] = $benchmark-&gt;concurrentTest($times, $limit); // 20
    $stop = $timer-&gt;stop();

    // 44 calls, 22 db, 22 normal
    foreach($rs as $v){
        var_dump($v);
    }

    return $stop;
}

// start test
$times['syar'] = test('syar');
$times['fpm'] = test('fpm');
var_dump($times);

---------------------------
output: 

array(2) {
  ["syar"]=&gt;
  float(0.01271)
  ["fpm"]=&gt;
  float(0.08602)
}

function test($type, $times = 5, $limit = 5){

$timer = new Timer();

$benchmark = new Benchmark($type);

$rs[] = $benchmark->simpleTest(); // 2

$rs[] = $benchmark->dbTest($limit); // 2

$rs[] = $benchmark->batchTest($times, $limit); // 20

$rs[] = $benchmark->concurrentTest($times, $limit); // 20

$stop = $timer->stop();

// 44 calls, 22 db, 22 normal

foreach($rs as $v){

var_dump($v);

}

return $stop;

}

// start test

$times['syar'] = test('syar');

$times['fpm'] = test('fpm');

var_dump($times);

---------------------------

output:

array(2) {

["syar"]=>

float(0.01271)

["fpm"]=>

float(0.08602)

}

在当前测试环境下，fpm环境下的执行时间大概是syar下的4 — 6倍左右，稍后做更详细的压力测试，服务器、客户端资源占用情况测试

composer从私有资源库安装

2016年9月20日 by admin·已关闭评论

了解

资源 https://getcomposer.org/doc/05-repositories.md#loading-a-package-from-a-vcs-repository
包定义 http://docs.phpcomposer.com/04-schema.html

可安装的资源分类

composer 主要的资源库定义一个 packages.json, 定义各类包及版本，一个版本可以理解为一个包，必须包括name, version, dist or source, 在dist or source定义路径(type and url), type的取值包括：git, svn, fossil, hg, perforce, zip, rar, tar, gzip, xz , phar, file, path
vcs, git仓储/svn, 可以是github、私有git库、svn
pear, 不解释
package，没有使用psr规范的普通库

建立自己私有资源库

使用packagist or satis创建composer类型的资源库,
参考github.com/composer/packagist， github.com/composer/satis
Path 定义包路径
Artifact 归档类型 (zips, tar..)

定义包资源库地址示例

    "require": {
        "stcer/demo" : "*",
        "stcer/j" : "0.1.0"
    },

    "repositories": [
        {
            "type": "path",
            "url":  "../stcer-demo",
            "options": {
                "symlink": false
            }
        },
        {
          "type": "vcs",
           "url":  "git@192.168.0.252:repos/j.git"
        }
    ],

"require": {

"stcer/demo" : "*",

"stcer/j" : "0.1.0"

"repositories": [

swoole task中的数据返回

2016年6月8日 by admin·已关闭评论

task中能返回的数据通过php的Serialization函数返回到worker进程，因此像Closure等不能被序列化的对象不能返回，包括$exception中可能包括Closure

    function onTask($serv, $task_id, $from_id, $data){
        if(!is_array($data) || !$data['id']){
            return new Exception("Invalid task data");
        }

        $id = $data['id'];
        if(!isset($this->callbacks[$id])){
            return new Exception("Invalid task id");
        }

        try{
            $callback = $this->callbacks[$id][0];
            $rs = call_user_func_array($callback, $data['data']);
            return $rs;
        } catch(Exception $e){
            return $e; // 可能出错，使work进程不能正常运行
        }
    }

function onTask($serv, $task_id, $from_id, $data){

return new Exception("Invalid task data");

}

$id = $data['id'];

$rs = call_user_func_array($callback, $data['data']);
