Stock fish isn’t working on iOS. Seems to not make it past e4

i am on an iPad trying to analyze my games, and stockfosh is going completely dead. The loading icon is spinning, but the timer is frozen. Maybe it’s a bug?

Do you mean the analysis on Chess.com or the engine on your device?

The in browser analyzer. I.e. go to the learn tab, click on stockfish, and paste pdf

It isn't stockfish, you must blame another.

Well I have been using stockfish to analyze my games and I developed a solid opening using it. It did this yeasterday and I though that it was just my internet, but my internet is fine. It didn’t work today either, so idk if it is the platform I am on or if it’s stockfish.

Are you using Safari? Have you tried a different browser?

I am using safari but chrome won’t work either.

Not working for me either after updating ios. Might be related to the Spectre/Meltdown "fixes" they put in, thats my guess.

Did u also get a bunch of web pages crashing and reloading due to a problem? Before updating?

Analysis doesn't run on the chess.com server but client-side with Javascript. So, if it is related to those patches, they are due to your local system patches.

I will say that earlier today, based on another forum topic, the Analysis board wasn't working for me. I tested again with self-analysis on a game, and it wouldn't work. My browser had an update and it now is working. (I use Firefox Developer's version).

I hope Apple does another update soon. Thanks for everyone’s insight in the issue. This is my only device and I’m not not sure about the chess.com app or the stockfish app. I can go without stockfish for a while .

Update coming soon to address this. 

Funny. It's usually the other way round with me.

Where is the correct place to report these issue, and get a ticket number, etc?  I use Help and then Report a bug”. I never get any acknowledgement it’s been received.  I submitted on this same issue.  Thanks.

Exactly, thats why I said after the iOS update. The patches for these flaws are going to be on the firmware/kernel level as well as the software level (eg the web browsers). So the fact that it stopped working right after my update makes me think its related. Totally possible its not, but my guess is that it is.

Stockfish.js wasnt written by chess.com and I dont think they have the know-how to do anything about it unfortunately :/ they might have scripters that can modify the script to get it working but most likely we will be waiting for someone else to update the script or even more likely an update to the web browers, OS, or device.

Nothing to do but wait   

If I have time today Ill throw up an analysis website on one of my servers and have my servers run it locally and feed thw results back to the browser for everyone. I have some serious server power but it will still be slower than what your used to, especially if lots of ppl use it, but at least itd be something. Il update the thread if I get to it today or tomorrow (might be going skiing so we'll see)

This should be fixed late Monday or Tuesday after next deploy. 

Thanks for the update. Can you tell us what exactly your doing to fix it? Is it a change to the script to make it single threaded (im using the definition of multi threaded loosely here for simplicity sake) and wondering if  there is a particular public repo you work with?

Im just curious  

Adding .js backup for browsers that don't support WASM.
