- tomscott.com - / tomscott - In the news today: a link which, when moused over or clicked on, crashes Google Chrome. It's a heck of a bug: but how does it work, and what does it have to do with "null-terminated strings"?
TECH DETAILS: code.google.com/p/chromium/is...
Jokes on you, Chrome on my computer don't need this link to crash.

I love all these old "Tom Scott explains some viral coding bug" videos. They're super succinct while still giving a totally satisfying explanation of the phenomenon.
Its amazing how similar code reading and mRNA duplication are. They both have a start string and a "null" string to finish. Amazing
In the end, its all bound to mathematics
@Juju Tze No, biologically mRNA synthesis starts and stops based on a specific DNA sequence, not because humans use coding to read mRNA.
It's start at methionine and ends at the stop codon
@@TD-yx8yo but mRNA is a sort of coding though
@@TD-yx8yo be it DNA or be it RNA, they're all codes that program our bodies. If I remember right, when I was in highschool learning about basics of coding, the code that we wrote in C++ is somekind of raw code, we must let computers translate that code into another code before running it. It's similar to DNA being the raw code and mRNA being the translated code, it's rules of this world anyway, like how math exists in every form on earth. the earth codings is much more complicated than human's codings tho.

replay a part if you want to get a heart attack
Tom has not changed. I thought this was uploaded recently, and tried the link on three different browsers to see if it would work.
So basically, Chrome gets terribly confused, panics, and runs away.
Crashing is a good thing, if there wasn't a crashing safeguard the data file will get corrupted and have an irreparable damage for both your computer and the server.
Sousuke Aizen Well, damn!
would you rather it blow up xD
Not really. Not handling exceptions can't cause data corruption unless it's a low level function (for example memory managment in C). And even if it bugs out at any low level the only data you lose is in RAM (or any *single* file your process has opened), which isn't that bad since most new programs (MS Office, some Chrome extensions) save multiple copies of the file (two in temporary dir, and one at real location) and auto-save every few minutes.
And don't get me even started on that "_both you computer *and the server*_" nonsense. Nothing would happen to the server.
SpiritWolf - where would it run to???
"If you're watching this in the future, it's probably fixed"
Me, genuinely upset that I won't be able to crash chrome today: 😔

You never know If you dont try
You can actually crash it by downgrading your chrome browser(do this on a computer that you don't need chrome on) to the update before the bug was fixed and it will work

Me: *sees this video* "Can't wait to try this out"
Also me: *sees that it was posted 7 years ago*
This is absolutely fantastic. Not only does it explain a rather subtle bug very well, it also does an incredible job at introducing pointers, memory representation and string termination. While these concepts seem simple once accustomed to them, they are rather tricky to explain to someone with no prior experience. Seriously, thanks a lot for this video! I will probably refer to it quite often in the future, taking 5 minutes to have someone watch it whenever I have to explain this stuff!

I feel sorry for the Chrome programmers. This would be incredibly frustrating to fix.
+hhaxden I've put a link in the description to the actual bug report on Google Code. To quote one of the developers: "this is a mess."
+Tom Scott To be fair, the mess you keep referring to from comment 14 isn't a mess because it is hard to fix, but because every possible fix seems to break standards compliance and violate expected behavior in some way. The mess isn't the effort in fixing but the effort in deciding which fix is appropriate.
Luckily comment 36 clarified exactly how the standards say it should be handled and sadly it was determined in subsequent comments that making chrome standards compliant in that respect would untenable due to some assumptions in the design of "the extra validation we do on receiving URLs over IPC" so they were back to deciding which way of breaking URL handling is preferable to fix the crash.
Honestly the code wasn't too bad, there was a one day turn around between deciding on what to change and merging the change into beta.
Great time to learn about it! 6 years, later..
Now it just says "This site can’t be reached, a’s server IP address could not be found."

Theres a video i picked this up on while attempting to build my own OS, its more or less the structure of the bios(sectorStartAddress, SectorLength), works the same for strings(StringAddress, StringLength), this essentially writes a new StringAddress and StringLength to the sector making the drive look for data that doesnt exist and is essentially null, windows force closes chrome/chromium to prevent further damage to data

Hey Tom, as the guy who fixed this bug in Chromium -- I'm not really sure why you spent so much time (or, really, any time at all) on null-terminated strings. It implies that the crash has something to do with misinterpreting an embedded null, which, as you said near the end of the video, isn't true. The crash has nothing to do with null-terminated strings.
Really the problem is simply that canonicalization wasn't idempotent when it was supposed to be. This could cause problems regardless of what value is ultimately encoded by the doubly-escaped string and there are a variety of places in which different bugs appeared as a result. It was too bad that right as you got to the point where I thought you'd explain one of these in more detail, the video ended :(
