Break event_base_dispatch from another thread

由 孤人 提交于 2020-01-30 05:58:37
问题 Can I call event_base_loopbreak to int event_base_dispatch(struct event_base *base) that run in another thread? 回答1: Calling event_base_loopbreak from outside of the event loop doesn't actually have an effect and inside the loop, event_base_loopbreak does not break from the loop. So, calling event_base_loopbreak to int event_base_dispatch(struct event_base *base) that run in another thread, should not have any effect. 回答2: I'm also meet the same issue, no matter calling event_base_loopbreak()

安装 libevent 出错: event.c error: ‘CLOCK_MONOTONIC’ undeclared checking build system type… configure: error: cannot guess build type; you must specify one –build=arm-linux 在编译 libevent-1.2 源码时, make 出错: event.c:157:20: error: ‘CLOCK_MONOTONIC’ undeclared (first use in this function) if (clock_gettime(CLOCK_MONOTONIC, &ts) == -1) ^ 出错原因是: 在 event.c 文件中 CLOCK_MONOTONIC 没有定义. 解决办法 : 在网上搜了下, 是缺少头文件了, CLOCK_MONOTONIC 定义在 time.h 头文件中. 所以可以直接修改源码: 在 event.c 中引用头文件: #include <time.h> : 来源： CSDN 作者： weixin_46202143 链接： https://blog.csdn.net/weixin_46202143/article/details/104011090

Libevent使用范例及代码说明

利用libevent实现有数据来时，执行ReadBuffer函数，支持多线程。 static EventApiParameter parameter; memset((void *)&parameter, 0, sizeof(parameter)); parameter.agent_socket.port = port; //parameter.write_function_point = WriteBuffer; parameter.read_function_point = ReadBuffer; parameter.timer=0; //event和event_base是libevent的两个基础结构体 struct event ev; struct event_base *base; //申请一个新的event_base base = event_base_new(); //设置ev,将fd回调函数OnAccept以及回调函数参数arg赋值到ev结构中 //event_set->event_assign event_set(&ev, fd, EV_READ|EV_PERSIST, OnAccept, (void *)parameter); //将base赋值到ev结构中，ev->ev_base = base event_base_set(base, &ev); /

Django个人博客搭建教程---使用memcached缓存页面

1、安装memcached sudo apt-get install memcached 由于memcached依赖于libevent；因此，还需要安装libevent,命令如下： sudo apt-get install libevent-dev 2、安装python3-memcached pip3 install python3-memcached 3、配置Django settings.py CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': [ '127.0.0.1:11211', ] } } 4、启动memcached sudo service memcached start 5、为页面函数添加缓存装饰器 @cache_page(60 * 15) def index(request): pass 来源： CSDN 作者： 请叫我算术嘉 链接： https://blog.csdn.net/ssjdoudou/article/details/104032599

Linux上Memcached的安装

由 让人想犯罪 __ 提交于 2020-01-18 08:28:00
首先去官方下载最新的版本,现在最新的是memcached-1.4.1 ,然后就编译安装了. 另外,Memcache用到了libevent这个库用于Socket的处理,所以还需要安装libevent，libevent的最新稳定版本是libevent-1.4.12 . 1.先进这个两个文件下载回来,放到临时目录下 cd /usr/local/src wget http://memcached.googlecode.com/files/memcached-1.4.1.tar.gz wget http://www.monkey.org/~provos/libevent-1.4.12-stable.tar.gz 2.将文件解压至 usr/local,此时将产生两个文件夹libevent-1.4.12-stable及memcached-1.4.1 3.切换至root用户 4.先安装libevent： tar zxvf libevent-1.4.12-stable.tar.gz cd libevent-1.4.12-stable ./configure –prefix=/usr/local/libevent make make install 5.安装memcached，安装时还要指定libevent的安装位置： tar zxvf memcached-1.4.1.tar.gz cd

libevent: http://libevent.org/ 服务器端：https://code.google.com/archive/p/memcached/downloads 客户端： http://pecl.php.net/package/memcache 和 http://pecl.php.net/package/memcached 二选一 http://chenzhou123520.iteye.com/blog/1933489 https://blog.linuxeye.com/345.html http://chenzhou123520.iteye.com/blog/1925209 http://www.cnblogs.com/scotoma/archive/2011/02/15/1955573.html 最近在公司服务器上安装memcached安了很多次，每次都得上网来查一下步骤，今天干脆写个详细点的步骤记录一下，留作备忘。 一、检查libevent 首先检查系统中是否安装了libevent Shell代码 rpm -qa|grep libevent 如果安装了则查看libevent的安装路径，后续安装时需要用到 Shell代码 rpm -ql libevent 如果没有安装，则先安装libevent 安装libevent： 1.首先下载libevent安装包

How to break out libevent's dispatch loop

由 风流意气都作罢 提交于 2020-01-15 09:10:34
问题 I've implemented a tiny webserver in a separate thread using the nice libevent library. The webserver runs event_base_dispatch() to process all events. What I need is a way to break out this dispatch loop from the main thread. It boils down to the following C++ code: #include <stdlib.h> #include <signal.h> #include <thread> #include <evhttp.h> struct event_base *eb; std::thread t; static volatile sig_atomic_t bailout = false; void my_signal_handler(int) { bailout = true; } void onRequest
