"CKB v0.105.* have bugs. Please upgrade to the latest version."

Weird alert appears on testnet

Link: https://pudge.explorer.nervos.org/

Trying to find out which API throws it

[Keith-CY]

From API https://testnet-api.explorer.nervos.org/api/v1/statistics/blockchain_info

[iamyates]

this message comes from CKB node's RPC method: get_blockchain_info: ( then stored in backend's cache, then served in response , then shown at frontend )

# echo '{
    "id": 3,
    "jsonrpc": "2.0",
    "method": "get_blockchain_info",
    "params": []
}' \
| tr -d '\n' \
| curl -H 'content-type: application/json' -d @- \
http://localhost:8114

response:

{
    "jsonrpc":"2.0",
    "result":{
        "alerts":[
            {
                "id":"0x134af71",
                "message":"CKB v0.105.* have bugs. Please upgrade to the latest version.",
                "notice_until":"0x18785a51000",
                "priority":"0x14"
            }
        ],
        "chain":"ckb",
        "difficulty":"0x95fff367010ed96",
        "epoch":"0x59c0532001b0b",
        "is_initial_block_download":false,
        "median_time":"0x185bebd5475"
    },
    "id":3
}

And it seems both ckb node 0.105 and 0.106 receive this alert message ( not test on 0.104 or ther versions )

This message will be filtered out by the backend

The alert message is still returned in the API, it was fixed in the front-end temporarily

[iamyates]

the backend caches this alert message for 6 hours. so when deploy, we should clear the redis. sorry I forgot to figure this out.

[Keith-CY]

Confirmed that the alerts is empty
