例如，你可以实现一个无状态的「重置密码」功能而无须在数据库中存储 token

这个例子简直就是坑人吧……

#108 楼 @leaz python 版本不一样吧。

mysql 能编译么……

#63 楼 @xdite wordpress 的 xml 导入失败。。

#19 楼 @luikore 多谢了 QAQ

#17 楼 @luikore 不是……因为程序上的原因，包装 C++ 类的东西把它当做没有 mark 吃掉了。。 然后另一边又把它当做有 mark 的…… 所以造成了 mark 被调用的假象，那个 mark 的调用不是吃 Ruby 来的。。

#15 楼 @luikore 卧槽……不对，mark 根本没被调用。。

多谢……解决了……

因为各种坑爹的原因，mark 没被调用&#%#￥%#￥%#%

#13 楼 @luikore

["RgeDx.rb:32:in `compressLLPos'", "RgeDx.rb:60:in `block in <main>'", "RgeDx.rb:59:in `each'", "RgeDx.rb:59:in `<main>'", "RgeCore:in `eval'"]

---------------------------
确定   
---------------------------

我什么都看不懂了……看起来是在 compressLLPos 的时候分配内存然后被回收了……这不科学啊！！

#11 楼 @luikore gc_mark 的析构是包装的时候手动调用的……问题就是为什么_rb_free 被调用了…… ps 大概 sprite 没机会挂掉……

@sprite.vss.update
while @dx.update
  for j in 0...120
    pos = compressLLPos(rand(800),rand(600),@texture.width,@texture.height)
    for i in 0...6
      @sprite.vss[j*6+i].x = 1#pos[i][0][0]
     # @sprite.vss[j*6+i].y = pos[i][0][1]
     # @sprite.vss[j*6+i].u = pos[i][1][0]
    #  @sprite.vss[j*6+i].v = pos[i][1][1]
    end
  end
  @sprite.vss.update
end
@sprite.dispose
@dx.dispose

#9 楼 @luikore 知道…… 之所以肯定 GC 有问题的另一个原因就是’‘GC.disable’‘之后世界安静了……

#3 楼 @luikore vectorSetting 是用 ruby_xmalloc+rb_data_object_alloc……大概不是这个问题吧，因为 vectorSetting 确实是被 Ruby 的 GC 回收掉了，而不是 C++ 调用的析构函数。这个从断点的栈视图可以看出来。。 cmark 和 cfree 肯定没反……也包装过了。。应该不是后两个的问题。。

#1 楼 @luikore

void CSprite::Mark(){
    if (disposed) return ;
    if (vectorShader) RB->GcMark(vectorShader->GetValue());
    if (vectorSetting) 
        RB->GcMark(vectorSetting->GetValue()); // 断点1
/*
        virtual void                    GcMark(VALUE obj)                                                               { rb_gc_mark(obj); }

*/
    if (m_texture) RB->GcMark(m_texture->GetValue());
    if (pixelShader) RB->GcMark(pixelShader->GetValue());
    if (pixelSetting) RB->GcMark(pixelSetting->GetValue());
};
    class  SolidVectorShaderSetting : public VectorShaderSetting{
    public:
        void Setup(IDirectX * idx_);
        virtual void DxSetup();
        void update();
        void Resize(int target); // target > 0
        virtual int GetSize();
        SolidVectorShaderSingleSetting * GetVector(int x);
        virtual bool NeedDraw();
        virtual void Mark();
        static bool HaveMarkProc() { return true; }
    protected:
        ID3D11Buffer* vertexBuffer_;
        int size;
        SolidVectorShaderSingleSetting * settings;
        IDirectX * idx;
        bool CanDraw;
    public:
        SolidVectorShaderSetting(){vertexBuffer_ = NULL;CanDraw = false;size = 0;settings = NULL;}
        virtual~SolidVectorShaderSetting(){
            SAFE_DELETE_ARRAY(settings);  // 断点2
            SAFE_RELEASE(vertexBuffer_);
            CanDraw = false;size = 0;
        };
    };

我设置了这两个断点……然后断点 1 和断点 2 分别被断到……这怎么解决。

排序之后 O(N)。
