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.
*/
asmlinkage void schedule(void)
(…)
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…
