Event-driven network library for multi-threaded Linux server in C++11
今天发现产生了coredump，用gdb查看了一下，信息如下： (gdb) bt #0 0x0000003af34690e6 in setbuffer () from /lib64/libc.so.6 #1 0x00000000004f6110 in muduo::LogFile::rollFile() () at /home/suyl/project/muduo-1.0.9/muduo/base/LogFile.cc:101 #2 0x00000000004f541c in muduo::AsyncLogging::threadFunc() () at /home/suyl/project/muduo-1.0.9/muduo/base/AsyncLogging.cc:101 #3 0x00000000004faf6a in muduo::detail::startThread(void*) () at...
移植了一个ios，但在增加ipv6支持后出现一个问题： return ::connect(sockfd, addr, static_cast(sizeof(struct sockaddr_in6))); 回返回errno 22: Invalid argument errno 以上代码改成：return ::connect(sockfd, addr, static_cast(sizeof(*addr))); 后就正常了
Although I cannot find error examples at present. But I think which keep consistent in err_ and errno is a better way with considering it have no need of additional...
在服务端RpcChannel和TcpConnection绑定，当TcpConnection断开的时候，RpcChannel被销毁，在这之后触发Callback会访问非法内存。
hiredis 模块又一个小问题，redis启动，正常链接时候没什么问题，如果redis没有启动，会出现一直pollhup日志，这个问题我觉得主要在hiredis封装设置channel时没有设置closecallback导致，句柄一直没有删掉， 我尝试给hiredis模块增加一个handclose函数，如下 void Hiredis::handleClose() { ::redisAsyncHandleRead(_context); } setchannel时做下如下操作 _channel->setCloseCallback(std::bind(&Hiredis::handleClose, this)); 这样问解决了

AsyncLoggin单条日志的大小受到muduo::detail::kLargeBuffer的限制，超过此大小的日志写不进去
消除`void TcpConnection::send(Buffer* buf)`中buf的**copy** `retrieveAllAsString`函数会生成一个临时的**string**，造成内存**copy**，使用`std::move`消除内存拷贝
