不是可以 ctrl+v 粘贴吗？

@4679kun 我的场景是在公司内网搭建静态博客，没有搜索能力别人就不能检索内容了。

@4679kun 请问 hugo 的本地搜索有什么好的方案？

手机打字，纠正上面单词错误 ，volatile

@mind3x 确实，应该添加volarile 关键字，感谢。

hashMap要么是旧的Map要么是新的Map ，没啥问题，copyonwritehashmap就这么实现

@phx13ye memcache 的通信协议里没有对请求进行标识么，没了解协议细节😓

netty4不是特别确定，但是对于netty3来说，客户端（channel）写实际上是往底层一个缓冲队列里写消息，然后nettyio线程从队列依次取消息发送，所以是不是要保证a确实先写入到缓冲队列才行？

摘自jvm规范（2.6）
A frame is used to store data and partial results, as well as to perform dynamiclinking, return values for methods, and dispatch exceptions.A new frame is created each time a method is invoked. A frame is destroyed whenits method invocation completes, whether that completion is normal or abrupt (itthrows an uncaught exception). Frames are allocated from the Java Virtual Machinestack (§2.5.2) of the thread creating the frame. Each frame has its own array oflocal variables (§2.6.1), its own operand stack (§2.6.2), and a reference to the run-time constant pool (§2.5.5) of the class of the current method.
A frame may be extended with additional implementation-specific information, such asdebugging information.The sizes of the local variable array and the operand stack are determined atcompile-time and are supplied along with the code for the method associated withthe frame (§4.7.3). Thus the size of the frame data structure depends only on theimplementation of the Java Virtual Machine, and the memory for these structurescan be allocated simultaneously on method invocation
