[BUG]: Swaps history break

[tonymorony]

Describe the bug

I've used the app quite actively and performed over than 30 swaps as maker and taker, on some point my "Recent swaps" page cleared and new swaps not displaying here however DB is still there. I suspect that some swap file broke it, investigating.

App version: latest dev, OS: Windows

Log: history_adex.log

Noticed adex-api panic in log, maybe it's related:

10 07:08:23, common:438] panicked at '

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!   unwrap! called on Result::Err                                              !

mm2src\coins\lp_coins.rs:397,9 in coins

Err(Os { code: 87, kind: Other, message: "The parameter is set incorrectly." })

By bisection method I've found a file caused it (without this one tx history displaying fine):

6462abf3-bcb9-46dc-bd55-693361d147e4.zip

It's a swap with "StartFailed" event (btw mm2 panic unrelated to that problem)

[tonymorony]

that looks like exactly the same problem as in #234 so it's not fixed it seems

@tonymorony Do you see the panic repeatedly or it happened just once? It was caused by this code https://github.com/KomodoPlatform/atomicDEX-API/blob/08d013c6a5983ccb590b246a5600387f9918a805/mm2src/coins/lp_coins.rs#L397, history cache file failed to be renamed and panicked due to unwrap, we should handle this gracefully on MM2 side. Could you please open an issue in AtomicDEX-API repo for further investigation?

[tonymorony]

@artemii235 I can see it on every GUI startup, sure will open the issue now

I'm following this one, thanks for the issue @tonymorony

I'm following this one, thanks for the issue @tonymorony

great! yea, would be superb if GUI can handle "type": "StartFailed" swaps

[tonymorony]

fixed in #349
