MAC OSX 上, client.crypt 库会导致 LUA 的标准输入IO卡住。

[Gowa2017]

复现代码：

package.cpath = "luaclib/?.so"

local socket = require "client.socket"
local crypt = require "client.crypt"
local input = io.read()
print(input)

if _VERSION ~= "Lua 5.4" then
	error "Use lua 5.4"
end

链接和执行脚本时，使用的 LUA 都是 3rd/lua 下面编译的LUA版本。

OSX 版本：13.3.1

编译指令：

make luaclib/client.so
cc -g -O2 -Wall -I3rd/lua  -fPIC --shared lualib-src/lua-clientsocket.c lualib-src/lua-crypt.c lualib-src/lsha1.c -o luaclib/client.so -lpthread

编译器：

cc -v
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: x86_64-apple-darwin22.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

请问是我环境问题或是 CRYPT有一些操作会屏蔽输入？

补充，使用LLDB来看，似乎是开了两个线程，LUa-clientsocket 也在读标准输入：

使用 socket 来读取输入就行了。解决。
