你遇到过的源代码中最好的注释是什么?


当前回答

几年前我在。h文件里看到的。

// It may be a hack, but it works.

其他回答

在一个生成HTML的旧perl脚本中找到:

# I would be _very_ brain farting if I said this code didn't need reviewing.
# It will make babies cry, and hair grow on your back, so please don't use it

这是我自己代码中的一个,但它仍然非常有趣,我认为最好还是把它放在网上,因为它是在公共SVN中。

// These were orginally up and down. When it was clear the names were
// inapplicable, they were renamed to retain the joke.
// Sorry if you were hoping for useful variable names.
quantum strange, charm;

注意上面代码中的bug;我只是证明了它是正确的,并没有尝试过。

这是唐纳德·克努斯写的。

在linux 1.0内核调度器(schedule .c)中:

Dijkstra可能讨厌我。

/*
 *  'schedule()' is the scheduler function. It's a very simple and nice
 * scheduler: it's not perfect, but certainly works for most things.
 * The one thing you might take a look at is the signal-handler code here.
 *
 *   NOTE!!  Task 0 is the 'idle' task, which gets called when no other
 * tasks can run. It can not be killed, and it cannot sleep. The 'state'
 * information in task[0] is never used.
 *
 * The "confuse_gcc" goto is used only to get better assembly code..
 * Dijkstra probably hates me.

try {
  dataSource.close();
}
catch (SQLException ex) {
  // Do nothing, since we're going to trash this anyway
}

当然,这类事情实际上是JDBC(或者至少是Oracle的JDBC驱动程序)中的wtf,因为它可以在关闭连接时抛出SQLExceptions…
