iMega / spawn.lua

Created December 22, 2017 09:38 — forked from neomantra/spawn.lua

Using LuaJIT FFI, spawn a Linux command in the background.

	-- Spawn a command in the background, optionally redirecting stderr and stdout
	--
	-- requiring this file returns a function(cmd_line, stdout_redirect, stderr_redirect)
	--
	-- `cmd_line` is the command with possible arguments
	-- optional `stdout_redirect` is io.stdout, io.stderr, or a filename. default/nil is io.stdout
	-- optional `stderr_redirect` is io.stdout, io.stderr, or a filename. default/nil is io.stderr
	--
	-- Example:
	-- luajit -e 'require("spawn")("cat /etc/network/interfaces", "foo1", io.stdout)'

Как отслеживать все поведение распределенной транзакции?

	## 系统执行一条SQL，到底慢在哪里？

	如何跟踪一个分布式事务的所有行为？使用 [opentracing](http://opentracing.io/)！ opentracing 是一个标准的分布式 tracing 的协议。支持 Go, JavaScript, Java, Python, Ruby, PHP, Objective-C, C++, C# 等等许多的语言（暂时没看到 rust 的库）。

	[一些基本的概念](https://github.com/opentracing/specification/blob/master/specification.md#the-opentracing-data-model)：一个 Trace 是由许多 Span 构成的一个有向无环图。Span 之间的边的关系叫做 Reference。

	Span 里面的信息包括：操作的名字，开始时间和结束时间，可以附带多个 key:value 构成的 Tags(key必须是string，value可以是 string, bool 或者数字)，还可以附带 Logs 信息(不一定所有的实现都支持)，也是 key:value形式。

	下面例子是一个 Trace，里面有8个 Span：
