runtime.SetCPUProfileRate 最终调用到了 setThreadCPUProfiler 函数,该函数使用 time_create 开启了一个定时器,并设置定时器间隔时间是1s/100=10ms;该定时器会每 10ms 向所在线程定时发送 SIGPROF 信号,代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // runtime

微服务框架也是可以用于开发单体架构(monolith architecture)的应用。并且,单体应用也是最小的、最原始的、最初的项目状态,经过渐进式的开发演进,单体应用能够逐步的演变成微服务架构,并且不断的细分服务粒度。微服务框架开发的单体架构应用,既然是一个最小化的实施,

If you want to add new BASIC keywords this is easy, and the samples mentioned above do that. The following obvious primitives work as you'd expect: DIM Create an array. Note that only one and two-dimensional arrays are supported.
