问题 I am new to Bokeh and trying to implement a Slider callback using CustomJS. I have my sales data grouped by years, months, days.

regex replace with callback in c++11?

由 不问归期 提交于 2020-04-12 07:34:08
问题 Is there a function of regex replacement that will send the matches to user function and then substitute the return value: I've tried this method, but it obviously doesn't work: cout << regex_replace("my values are 9, 19", regex("\d+"), my_callback); and function: std::string my_callback(std::string &m) { int int_m = atoi(m.c_str()); return std::to_string(int_m + 1); } and the result should be: my values are 10, 20 I mean similar mode of working like php's preg_replace_callback or python's re

is it necessary to gchandle.alloc() each callback in a class?

问题 I have a .NT class which has multiple delegates for callbacks from native code. Is it necessary to allocate all the delegates? I mean does GCHandle.Alloc() protects just the delegate or the entire class that owns the delegate from being collected? 回答1: A delegate has two relevant properties, Method and Target. The Target will be non-null if the delegate was created for an instance method. And that keeps the object alive, as long as the garbage collector can see the delegate instance. Native

Event Loop event loop 对象包含两个部分：event 和 loop。event 负责 I/O 事件通知而 loop 负责循环处理 I/O 通知并在就绪时调用回调。这里 event 的含义与 select 中的 event mask 类似。 BaseEventLoop 类实现了基本的 loop 部分，而类似于 BaseSelectorEventLoop 这样的类实现了基于 selector 的 event 部分。 event loop 内部维护着两个容器： _ready 和 _scheduled 。类型分别是 deque 和 list 。_ready 代表已经可以执行，_scheduled 代表计划执行。_scheduled 中的 handle 是可以 cancel 的。 一次 loop 的基本流程可以参见 _run_once() 方法，其说明文档如下： This calls all currently ready callbacks, polls for I/O, schedules the resulting callbacks, and finally schedules 'call_later' callbacks. 流程为： 将 _scheduled 中已 canceled 的 handle 去掉 检查 _ready 和 _scheduled

关于跨域攻击和网络信标【转】

由 好久不见. 提交于 2020-04-06 19:45:55
关于跨域攻击和网络信标 一、什么是跨域访问 凡是与主站地址的域名、端口、协议不一致的其他请求，都可以认为是跨域访问。例如某网站的主站地址是 https://www.abc.com,但网页又... （地址是 https://img.abc.com ），这就是一种跨域访问。 二、浏览器的同源策略 所谓的同源策略是浏览器所遵循的一种安全约定。其限制了来自不同源的document或者脚本对当前的document读取或设置某些属性。具体限制如下： 跨源网络访问：AJAX请求。 跨源 DOM 访问：DOM。 跨源脚本API访问： iframe.contentWindow, window.parent, window.open 和 window.opener 如果没有这些限制，那我们就可以肆无忌惮的破坏其他网站的网页了。 三、如何进行跨域访问 跨域访问不是跨域攻击，业务上我们的确有跨域访问的需要。 #### 1、通过标签的src或者href属性。 例如< script >、< img >、< iframe >、< link >，访问静态资源文件虽然是跨域，但不受同源策略限制，因为使用的是标签访问。src属性访问的地址是一次性的get访问，且是主站主动设置，相对安全。 2、form表单提交。 form表单提交到其他域也是被允许的。因为form提交意味着跳转到新的站点，是一个有去无回的页面跳转
