Yaf 3.2 发布

经过俩周多的重构,终于一咬牙今天发布了Yaf 3.2.0 beta, 要不然一直在想各种可能的优化点,不停的写,没完了, 🙂

这次的重构的最初出发点是把原来的Yaf对象从PHP的原生对象,改成了自定义的对象:

结构重构

之前的Yaf版本,比如我们拿Yaf_Request为例,它原来是一个PHP的对象,它有属性,用起来也跟用户在PHP中定义的对象一样,比如在之前的版本的Yaf中,在扩展中如果要获取Request对象的uri属性,那么:

zend_read_property(yaf_request_ce, obj, “uri”, sizeof(“uri”)-1, 1, NULL);

去”读取“这个request对象的uri属性,一定程度上这个有一定的历史原因,毕竟这个Yaf是十年前写的:)

而在3.2.0以后,Yaf_Request对象成为了一个纯粹的C结构体:

typedef struct {
    zend_uchar  flags;
    zend_string *method;
    zend_string *module;
    zend_string *controller;
    zend_string *action;
    zend_string *base_uri;
    zend_string *uri;
    zend_string *language;
    zend_array  *params;
    zend_array  *properties;
    zend_object std;
} yaf_request_object;

这样的定义如果大家看过我之前的文章深入理解PHP7内核之Object应该不会陌生,当用户在PHP脚本端获取到Yaf_Request对象的时候,对应的就是yaf_request_object.std这个成员。

这样以来,如果要获取uri的话,只需要根据偏移量,从std获取到yaf_request_object的地址,然后(yaf_request_object)->uri,就可以了。这样性能就会有较为明显的提升。

所有的Yaf提供的类都被重写成这种形式,但这样以来就需要模拟PHP的对象行为,让用户在PHP脚本中也想获取Yaf_Request对象的uri属性的时候,也可以正常访问。

另外,就是对缓存友好的提升,除了尽量降低内存使用以外,举一个例子:比如原来的时候,对全局变量的使用较多, 主要是指YAF_G(),这样对于一些很热点的函数来说,如果使用了太多的全局变量,对缓存也不够友好,于是把很多flag类的字段,收敛到了对象本身,比如对于Yaf_Loader, 他需要关注是否启用了use_spl_autoload, name_suffix, name_separtor以及lowercase_path等多个flag, 原来都是需要访问Yaf_G(). 现在统一都收敛到了yaf_loader_object->flags中。(实际上是复用了std.properties_table[0].u2.var_flags字段作为flags,没有新增内存)

#define YAF_LOADER_FLAGS(loader)  YAF_VAR_FLAGS(loader->std.properties_table[0])
typedef struct {
    zend_object std;
    zend_string *library;
    zend_string *glibrary;
    zend_array  *properties;
} yaf_loader_object

PSR-4 Autoloading

另外这次对自动加载器新增了部分PSR-4的支持,用户现在可以申明一个namespace的加载路径:

Yaf_Loader::getInstance()->registerNamespace(“\Foo\Bar”, “/var/lib/foo”);

那么所有在\Foo\Bar命名空间下的类就会从/var/lib/foo目录下查找:

\Foo\Bar\Dummy  -> /var/lib/foo/Dummy.php

当然你也可以在配置文件中注册namespace path:

application.library.namespace./Foo/Bar=“/var/lib/foo”
不过为了兼容老的加载协议,下划线还是会被认为是目录分割符.

\Foo\Bar\Ver_Don -> /var/lib/foo/Ver/Don.php

性能提升

这次的重构本质上还是为了性能提升, 那实际效果如何呢?

为了能较为真实的反应测试,我采用了Yaf代码下的demo生成器tool/cg/yaf_cg来生成一个完整的Yaf应用框架,然后通过cachegrind来详细对比。

tools/cg/yaf_cg -d yaf

首先php-7.4 , yaf-3.1.4, 跑1000次 :

 valgrind --tool=cachegrind /path-to-php74/bin/php-cgi -T 1000 index.php

对比结果:

3.1.4 3.2.0 Detal
IR 232,666,798 171,236,262 -26%
I1 Misses 3,669,999 2,940,070 -20%
DR 102,960,876 75,584,870 -27%
D1 Misses 5,065,700 4,302,787 -15%
Branch 44,906,888 32,043,848 -29%
MisPred 4,112,611 3,033,847 -26%

我们可以看到,无论执行的指令数,访问的内存数,以及cache miss, branch mispred都有很明显的下降。
当然,我们也能看到D1 Misses想对于DR的下降不成比例,这部分的主要原因还在于用户脚本访问Yaf类对象的时候导致的新增差异,后续还要想想怎么提升这块。

总体来说,这次的重构获得了20%以上的性能提升,但这个只是针对框架本身,对实际使用Yaf的业务来说,那肯定没这么明显了,具体多少大家可以自行测试。

好了,就简单介绍这么多,具体详细变化可以参看Changelog, 欢迎下载测试Yaf-3.2 后续我来慢慢完善文档。

前面也说了,这次对版本代码量变更很大,几乎相当于重写了:

新增代码量就将近9000,鉴于此,3.2.0目前发布为beta,虽然我做了很多的测试,也做到了能想到的最大可能去保证行为不发生变化,但还是不能保证完全对以前的版本兼容,大家如果在使用的过程中有任何问题,欢迎即时在Github反馈。

    pecl有时候安装扩展真的好慢,甚至打不开,有没有那种国内的源,鸟哥

    问下大神,开发扩展,怎么避免内存泄露呢,用Valgrind好像逻辑走不到的地方检测不到泄露

    • Laruence
      Laruence April 22, 2020

      没啥好办法,一般来说,处理好引用计数就好了,用的时候+1,用完了-1,经验多了就好了

        PHP的扩展里面用emalloc,其实就算不释放,在请求结束后PHP也会释放掉所有申请的非持久型内存吧。

        • laruence
          laruence May 13, 2020

          理论上是,但是内存如果不及时释放,会导致峰值内存变大,间接还是会影响性能

            嗯,这个到是的,如果确实短时间内找不到问题所在,可以设置一下max_request,再配合php自动内存释放,可以临时应急用用。当然最好还是能开着debug mode做测试,把大部分路径都覆盖到,这样基本上问题不大了。
