除了《静态分析C语言生成函数调用关系的利器——calltree》一文中介绍的calltree,我们还可以借助cflow辅助我们阅读理解代码。(转载请指明出于breaksoftware的csdn博客)
int listenfd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); struct sockaddr_in serv_addr; memset(&serv_addr, 0, sizeof(serv_addr)); serv_addr.sin_family = AF_INET; serv_addr.sin_addr.s_addr = htonl(INADDR_ANY); serv_addr.sin_port = htons(8080); bind(listenfd, (struct sockaddr...

基于C++的调试对于已经到Python虚拟机中存储起来的字节码命令是无法被观察到的,我们只能把它们解析成AST才能看懂字节码在解释器内存中的状态,所以这里我们借用Python解释器里的C_API来输出我们的对象:
followed by ports). RedisCluster gets cluster information from one of the seeds at random, so we don't need to pass it all the nodes, and don't need to worry if new nodes are added to cluster. Many methods of Credis_Cluster are compatible with Credis_Client, but there are some diff...
For me other people making money out of something I wrote is not something that I lost, it is something that I gained. Redis 使用 BSD [14] 。 Arts are one of the few things worth life's best efforts. Programming is art, if done in certain ways. ...
Redis从2.8开始正式提供了Sentinel(哨兵)架构来解决这个问题 哨兵模式能够后台监控主机是否故障,如果故障了根据投票数自动将从库转为主库。哨兵模式是一种特殊的模式,首先Redis提供了哨兵的命令,哨兵是一个独立的进程,作为进程它会独立运行。哨兵通过发送命令,等待Redis服务器响应,从而监控运行的多个Redis实例...
此外,该库还提供了常见应用的客户端通信库(如:HTTP、SMTP、ICMP、MQTT、Redis、Memcache、Beanstalk、Handler socket),常见流式编解码库:XML/JSON/MIME/BASE64/UUCODE/QPCODE/RFC2047 etc。1.1、库组成本工程主要包含 4 个库及大量示例。4 个库的说明如下:lib_acl: 该库是最基础的库,其它 3 个库均依赖于该...
