Because don't log close error, so not knowing the root cause, but can has some doubt when fields too much, seems like that the channel is closed.maybe due to msg size!solution：add logInfo when fail；make eventset number per vector configurable？但是用户也不清楚多大好，最好是...

bossGroup 线程组实际就是 Acceptor 线程池,负责处理客户端的 TCP 连接请求,如果系统只有一个服务端端口需要监听,则建议 bossGroup 线程组线程数设置为 1。workerGroup 是真正负责 I/O 读写操作的线程组,通过 ServerBootstrap 的 group 方法进行设置,用于后续的 Channel 绑定。

gRPC并不是fork safe的,如果在fork之前创建channel,可能会碰到deadlock或者报错,取决于你用的gRPC版本。。。我使用的1.36版本会检查fork,如果channel在fork之前创建且未close,会raise‘ValueError: Cannot invoke RPC: Channel closed due to fork’,之前用的忘记是啥版本的会deadlock。想要在client侧使用多进程,合理的...
我使用的1.36版本会检查fork,如果channel在fork之前创建且未close,会raise‘ValueError: Cannot invoke RPC: Channel closed due to fork’,之前用的忘记是啥版本的会deadlock。想要在client侧使用多进程,合理的方案是在fork之后,在每个子进程中创建channel,如果主进程有channel需要先close掉。multiprocessing/client给了...
channel 多路select 浅谈channel send操作 浅谈channel recv操作 channel 我们通过make创建一个缓冲区大小为5,元素类型为int的channel。ch是存在于函数栈帧上的一个指针,指向堆上的hchan数据结构。 type hchan struct { qcount uint // 数组长度,即已有元素个数 dataqsiz uint // 数组容量,即可容纳元素个数 buf...
