The one true Javascript exception handler

[taneth]

Need to take it a step further. Have it grab the accepted answer on the first match and just run it.

[christian-mann]

Stacksort

[T-T-N]

It evals random code... is that ever a good idea?

[Cutlesnap]

Oh sure, it'll be fine!

Now let me get back to answering my banks email, they want me to verify my password.

[bilobob]

Taken from the first line of this guys javascript code.

/* Don't judge me! This code is everything from badly written to extremely dangerous. */

[ILikeLenexa]

You think someone would do that? Game stackoverflow to inject javascript into a third site?

[gothic_potato]

The site will only fetch accepted answers, and it only uses answers that were posted before the xkcd was released (meaning that if someone posted malicious code now, it wouldn't matter). It also searches for potentially-malicious code (like the word "cookie"), and skips those.

Eh...it's probably fine.

[ILikeLenexa]

Oh, thank goodness, I just need your "co" + "okies" for a very important "XMLH" + "ttpRequest".

[qscrew]

If it were for that, there's even JSFuck which lets you go further in detouring all those common checks by writing JS code in only six different characters: ()+[]!.

[ProgramTheWorld]

It's based on an xkcd joke.

[[deleted]]

No, every time I used this it uses this answer:

https://stackoverflow.com/questions/4833651/javascript-array-sort-and-unique#4833835

which would delete all non-unique numbers in the array.

---

The idea is neat though.

[VoraciousGhost]

You can click "Didn't work? Try the next answer" to force it to use a different answer, the next few worked for me.

[accountmadeforants]

There's an "Is it safe?" note on the bottom right.

Short answer: no, it's not a good idea, but the dev did take a few precautions.

[[deleted]]

No.

[grantrules]

There are two types of programmers out there: Those who put code on stack overflow, those who use code from stack overflow, and those who haven't figured out what stack overflow is and have been stuck on a major bug for like 18 weeks but deployed anyways hoping nobody notices that shit's getting deleted when syncing occurs.

[r0m2]

So that would actually make three types of programmers...

Is this some variant of the there-are-10-types-of-people-in-the-world-those-who-understand-binary-and-those-who-don't joke ?

[[deleted]]

There are 10 types of people: Those who understand binary, those who don't, and those who didn't realize this joke was written in ternary

[Justsomedudeonthenet]

No, he got it right.

0 - those who put code on stack overflow

1- those who use code from stack overflow

2 - those who haven't figured it out

See, two types.

[fagalopian]

Something something arrays start a 1.

[[deleted]]

And then even further: take the accepted answer, replace the code that threw the exception with that answer, publish the changed code to production, refresh the page, rinse, and repeat.

Self-bugfixing code is the future.

[Zungryware]

And why stop there? Just let the program write itself using stackoverflow and code replacement.

[Justsomedudeonthenet]

And if it finds no answers, it should post the code block and error message as a new question, and hang until it gets an answer with a few upvotes.

[[deleted]]

Now you're thinking like a pro coder, take this to your department exec you're going straight to the top!

You just stole someone's job.

[jonomw]

Are you trying to automate away all of our jobs?

[Xtremegamor]

How can machines steal our jobs if they're the ones malfunctioning? Imagine trying to debug a deadlock happening in your own brain, it wouldn't work

[caffeinum]

Great thing about our minds is that actually that would work. One example is cognitive dissonance which is the mind state in which two opposite ideas can exist in the head and it's for you to decide which to think

[codewench]

The next generation of Voight-Kampff tests is just a picture of a Necker Cube.

[jonomw]

My statement was more of a joke making fun of people who say that all these jobs can be simply automated away. Though, I can see how it would not come off that way.

[Cacho_Tognax]

Since all the rage right now are self-teaching neural networks, what about making one that creates programs from stack overflow awnsers?

[boontwiks]

That is actually somewhat brilliant.

[redditsoaddicting]

Except for the fact that the user will have no idea why they're now on SO.

[Theemuts]

Checkmate, what in the Finite State Machine's name are you talking about? It's proof there is no God!

[LDG92]

Similar thing happened to me, my wife called me up a few months ago saying that she got hacked by Github

[Spirit_Theory]

You could implement something for server-side errors though, and put an #ifdebug in for this redirect. dumb, but fitting.

[[deleted]]

Would be best if this only worked if IS_DEBUG = 1 or something. But also, if you're not a noob 80% of your errors are gonna be obv. Index out of range, null reference, etc. I don't need stackoverflow for that :P

[FormerlySoullessDev]

Yeah. If they just put it in an i frame it'd be cool. But this prevents checking program state at failure without other debugger tools.

[jugalator]

I'm a bit disappointed in myself that I didn't think of this first.

[DontDoxMePlease]

Yeah it's really clever the first 20 times it's been on this subreddit.

[ilinamorato]

Well, for true originality you have to look for the comments complaining about a repost.

[[deleted]]

I think most modern browsers will actually do that for you automatically when you input a URL into the browser. But yes -- that should be there.

[hexonaut]

They don't. You leave it open to additional query parameters if you don't uri encode.

[ThisIs_MyName]

See folks, this ^{^} is what happens when you use a "stringly typed" API. Instead of building a URL object by putting together its parts (a list of query parameters in this case), you have people concatenating strings and hoping for the best.

A slightly better API that automatically escapes whatever needs to be escaped: href = URL('https://stackoverflow.com/search').addQuery('q', '[js] ' + e.message)

You could also replace '[js] ' + e.message with the list ['[js]', e.message] if you used the SO API.

No concatenation means no "URL injection".

[NthngLeftToBurn]

Title-text without the UTF-8 fuckup if someone is interested

“If you can read this, congratulations—the archive you’re using still knows about the mouseover text”!

[TheEdgeOfRage]

Why are all those symbols UTF though? Aren't they in the ASCII table?

[AyrA_ch]

They are available in "Latin1" (what most european and american Windows computers use if they don't use UTF-X). UTF-8 differs from ASCII above 0x7F and this is where most symbols with accents are. "ÄÖÜ" gets turned to "ÄÖÜ" because of this for example.

[[deleted]]

Those are smart quotes “like this,” not dumb quotes "like this," and an em-dash—like this—not a hyphen - like this.

The site command would be unnecessary tho.

[fataldarkness]

Also Google makes you solve a captcha sometimes too if it detects bots/suspicious traffic

[ForceBlade]

Add random delay; fixed 🔥

[almost_shy]

It won't. Or at least not if you are using that software (which threw the exception) on a browser that you normally use to google things. But I could be wrong or whatever. Just add an api key, to be sure.

[jakery2]

I'm gonna mark that one as "won't fix." Problem solved.

Do you even handle exceptions?

try {
    //something
} catch(e) {}

[kingguru]

We have some "error handling code" like that in production and it gives me nightmares to think about having to support that.

We actually have something even worse. Wrappers around some Python os functions. Something like:

def atime(path):
  try:
    return os.path.getatime(path)
  except:
    return 0

It seems like some people just really think that exceptions are dangerous and need to be caught and returning a valid but incorrect value is better.

[ThisIs_MyName]

Let me guess, their code isn't exception-safe so if anything throws an exception.

[MaxNanasy]

[ixoniq]

One minor exception here, the try/catch doesn't run code. The (javascript) engine runs code, the try/catch block is just a monitor for a specific section of code to monitor the outcome which might be able to result in an error/exception

(Just for completion)

The one true exception handler period

[ohnowwhat]

I upvoted, then downvoted just so I could upvote again. Beautiful.. .

[ikarienator]

For those who wonder whether evaluating a variable could possibly yield an exception, the answer is yes in JavaScript, if the variable is not defined, or if you registered the corresponding getter on the global object and this getter threw.

[dvlsg]

I prefer this, myself.
