Braiins pool not working with v2.0.5

[skot]

from twitter; https://x.com/der_hodler/status/1744807662947045797?s=20

i found a small bug in new firmware. you can no longer mine on http://eu.stratum.braiins.com. As soon as I enter another pool address like public pool it works. but brains no more. Worked before the update. Have tested it. i have 2 bitaxe. one public pool, one braiins.

I tried this myself and it also crashes. relevant log;

this is how it looks with public-pool

here is Braiins pool with v2.0.4

I (2353) stratum_task: Connecting to: stratum+tcp://stratum.braiins.com:3333 (159.223.18.138)

I (2793) stratum_api: Received result {"id":1,"result":[[["mining.set_difficulty","1"],["mining.notify","1"]],"00",6],"error":null}
I (2793) stratum_api: tx: {"id": 2, "method": "mining.configure", "params": [["version-rolling"], {"version-rolling.mask": "ffffffff"}]}

it seems that the issue is sending mining.configure before mining.subscribe

[benjamin-wilson]

I (2468) stratum_api: tx: {"id": 2, "method": "mining.configure", "params": [["version-rolling"], {"version-rolling.mask": "ffffffff"}]}
I (2528) stratum_api: Received result {"id":2,"result":null,"error":[21,"ConfigurationOutOfOrder",null]}

So the STRATUM_V1_configure_version_rolling function doesn't work (the parsing isn't correct) but if the order is reversed this function is skipped

[skot]

this seems related to #50

oh, I see what you mean.. Braiins is even complaining about it here; ConfigurationOutOfOrder

I (2391) stratum_api: tx: {"id": 1, "method": "mining.subscribe", "params": ["bitaxe BM1366"]}
I (2451) stratum_api: Received result {"id":1,"result":[[["mining.set_difficulty","1"],["mining.notify","1"]],"00",6],"error":null}

I (2571) stratum_task: rx: {"id":3,"result":true,"error":null}

Did some more work on this,

When the order is correct mining.subscribe does not immediately receive the correct response.

Example response: {“result”:[[[“mining.set_difficulty”,“731ec5e0649606ff”],[“mining.notify”,“731ec5e0649606ff”]],“e9695791”,4],“id”:1,“error”:null}

Actual response:

 I (3828) stratum_api: tx: {"id": 2, "method": "mining.subscribe", "params": ["bitaxe/BM1366"]}
I (3838) stratum_api: STRATUM_V1_subscribe Received result {"id":null,"method":"mining.set_version_mask","params":["1fffe000"]}

So instead of a response we're getting a mining.set_version_mask which was already done in the configure. At this point it seems to be an issue with braiins

I am using braiins with 2.1.7 and it's working. I already have received some sats from 1 week of mining through lightning...
