node.js – 在nodejs中使用longjohn时堆栈跟踪错误

我使用longjohn使用以下代码获得错误的堆栈跟踪.它显示从第一个函数调用setTimeout,但实际上程序在firstfunction执行之前崩溃.

我在这里创了一张票
https://github.com/mattinsler/longjohn/issues/16

var longjohn = require("longjohn");

setTimeout(function () {
    throw new Error();
}, 10);


setTimeout(function () {
    firstfunction();
}, 10000);


var firstfunction = function () {
    setTimeout(function () {
        console.log("First function");
    }, 10);
}

堆栈跟踪

/home/jeevan/node_js/node_modules/longjohn/dist/longjohn.js:181
        throw e;
              ^
Error
    at firstfunction (/home/jeevan/node_js/longjohn.js:11:11)
    at listOnTimeout (timers.js:110:15)
---------------------------------------------
    at Object.<anonymous> (/home/jeevan/node_js/longjohn.js:10:1)

我的问题是可能是什么问题,如何解决它.

它也没有longjohn.

我不知道为什么,但如果你给回调命名,它会更好：

setTimeout(function MyFirstTimeoutCallback() {
  throw new Error();
}, 10);
...

这会生成以下回溯：

/private/tmp/node_modules/longjohn/dist/longjohn.js:181
        throw e;
              ^
Error
    at MyFirstTimeoutCallback (/private/tmp/lj.js:4:9) <-- much better!
    at listOnTimeout (timers.js:110:15)
---------------------------------------------
    at Object.<anonymous> (/private/tmp/lj.js:3:1)
    at Module._compile (module.js:456:26)
    at Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Module._load (module.js:312:12)
    at Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:901:3

编辑：看起来这个错误是在节点0.10中引入的(某处).当我用0.8.23测试时,看起来没问题：

timers.js:103
            if (!process.listeners('uncaughtException').length) throw e;
                                                                      ^
Error
    at Object.<anonymous> (/private/tmp/lj.js:4:9) <-- correct
    at list.ontimeout (timers.js:101:19)
    ...

编辑#2：这是V8中确认的错误(请参阅链接的错误报告).
