Python script to convert mysqldump output to JSON file. Most of the code was borrowed from github.com/jamesmishra/mysqldump-to-csv
You'll want to update the 'parse_row' function to map each item in a row to a dictionary.

// 其实这题可以写的很简单,它的关键根本不是CAS操作。 | |
// 使用一个标志(flag也好,status判断也罢)来避免Start和Dispose重入是很容易 | |
// 想到的手段,很多同学也这么做了。大部分同学遇到的问题是:假如StartCore已经 | |
// 启动,那么如何让Dispose方法等待其完成。有些同学用while (true),有些同学用 | |
// 锁,但都避免不了让Dispose线程等待Start线程。 | |
// 这里“避免等待”的关键在于要跳出思维界限:谁说DisposeCore方法一定要在Dispose | |
// 方法里执行的?我们就不能在Start里销毁对象吗? |
