本来就要在写入的时候把要发送的字节数copy到rewriter以备之后重发, 不如就在写入的线程里, 只把要写的字节数刷到rewriter里, 然后通知负责flush的线程有数据要发送. flush线程负责从上次刷成功的index开始, 写入剩余未写入的部分. 这样子修改的好处是
- 合并多个小write
- 写线程单线程
- 逻辑简单, 写线程只负责把rewriter里的未发送成功的数据发出去, 重连成功和正常情况是一样的代码. 断线重连就真的只需要断开旧连接, 发起新连接的时候重置上次发送成功的index就可以.
需要额外处理发送得很慢的情况, 逻辑线程要写数据时, 未发送的数据数量超过了rewriter的大小. 可以考虑
- 超过了就直接断线, 有64k(根据配置)的数据没有发成功, 本来就表示这连接有问题
- 也可以临时增加rewriter的大小, 让逻辑线程可以把数据刷进去先返回. rewriter大小达到另一个配置的未发送消息的上限后, 断线
