Panic Crash from libcore/result.rs on Ubuntu 16.04.5 #190

jthompsonic · 2019-02-12T14:56:15Z

The grin-miner ran for several days producing grin in the grinmint.com mining pool. And then last night it had a panic and it stopped getting jobs to mine but the mining software did not crash altogether.

Here is the info when it starts:

Jan 31 12:06:49.625 INFO This is Grin-Miner version 1.0.2 (git v1.0.2), built for x86_64-unknown-linux-gnu by rustc 1.31.1 (b6c32da9b 2018-12-18).
Jan 31 12:06:49.625 DEBG Built with profile "release", features "CURSIVE, DEFAULT, OCL_CUCKAROO, OCL_CUCKATOO, OPENCL, TUI" on Thu, 17 Jan 2019 09:43:20 GMT.

and Here is where it crashed:

I'm seeing nearly the same thing about once every 2 days on only one machine. The final error is slightly different than above, but the rest of the stack backtrace is the same:

Thread 'client_controller' panicked with message:
"called Result::unwrap() on an Err value: Error("invalid type: integer 0, expected a string", line: 1, column: 558)"
See grin.log for further details.

For me, it happens as soon as we find an accepted share from grinmint. It seems to be the thread that is getting work from the pool. The miner will continue to hash, but will not receive or send jobs.

Single panic would kill controller_thread, as result no shares will be send to a pool while all solvers work fine. This pr reduces number of unwraps. Underlying reason for errors seems to be incorrect read impl, I'll address it in the next pr. Partially address mimblewimble#190 and mimblewimble#193

hashmap · 2019-02-15T13:37:52Z

I think #192 also fixes part of the problem. I tested those 2 prs, no panics.

However there may be still an issue with low-level socket read, but chances to see it are pretty low

quentinlesceller · 2019-02-15T14:59:29Z

Oh I somehow missed that issue. The issue was that Grinmint was sending a new line (\n) after the submit (share accepted) message. Which makes grin-miner crashs. So I think we can close this since it is a pool side issue.

sloppycoffee · 2019-02-15T15:13:03Z

Does grinmint know to fix it?

We already fixed it pool side. However grin-miner should not crash on this anyway. Leaving this issue open then.

vanities · 2019-02-15T17:30:20Z

@quentinlesceller Thank you!! I can confirm that we're back to mining with grinmint after accepted shares!

lukaszmatczak · 2019-02-18T13:55:28Z

@quentinlesceller Are you sure it's fixed properly? I'm still getting mentioned error.

quentinlesceller · 2019-02-18T14:21:30Z

@lukaszmatczak In which region (EU or US)?

jthompsonic · 2019-02-18T14:29:29Z

I am in the US and the problem appears to be fixed. I have been running several days now without incident. Thanks so much! 😁☕🌟

@lukaszmatczak I think one of our server in Europe is not updated yet. Try reconnecting again and you'll end up on a good one.

After this it simply never identifies another accepted solution. Is this related or is it something new?
