这段代码(位于ngx_event.c的ngx_process_events_and_timers函数中)可以清晰看到两种定时器机制。使用了timer_resolution指令,此处的timer将会被设置-1,否则就是调用ngx_event_find_timer()函数在定时器红黑树中找出最小定时时间。这个timer值最后将作为epoll_wait的超时时间(timeout)。此处需要注意timer_resolution指令...

3). 通过设置 timer_resolution指定更新的时间粒度 当配置了timer_resolution以后,nginx在启动时,会通过setitimer告诉内核,每隔多长事件发送一次SIGALRM信号,同时设置捕获信号的回调处理函数,在这个函数中设置标志位告诉事件处理模块需要进行事件的更新。需要注意的是,即便是在没有设置定时器的情况下,虽然通过ngx_process_...

Timer Interrupt Process When interrupts are used in assembly language programs, it is easier to predict the effect, as the programmer has more direct control over the exact sequence of the ISR. A C program is generated automatically by the compiler, so the precise timing that results from an ...
