Truffle: Initial migration hangs forever (parity POA)

[dmitrysenkovich]

Issue

I'm trying to create a private chain using parity (PoA) and truffle but when I do truffle migrate it hangs forever with the following output:

   > [
   >   {
   >     "jsonrpc": "2.0",
   >     "id": 24,
   >     "method": "eth_getFilterChanges",
   >     "params": [
   >       "0x0"
   >     ]
   >   }
   > ]
 <   [
 <     {
 <       "jsonrpc": "2.0",
 <       "result": [],
 <       "id": 24
 <     }
 <   ]  

Steps to Reproduce

Create a chain with the following custom_chain.json:

{
    "name": "DemoPoA",
    "engine": {
        "authorityRound": {
            "params": {
                "stepDuration": "5",
                "validators" : {
                    "list": [
                    ]
                }
            }
        }
    },
    "params": {
        "gasLimitBoundDivisor": "0x400",
        "maximumExtraDataSize": "0x20",
        "minGasLimit": "0x1388",
        "networkID" : "0x2323"
    },
    "genesis": {
        "seal": {
            "authorityRound": {
                "step": "0x0",
                "signature": "0x0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
            }
        },
        "difficulty": "0x20000",
        "gasLimit": "0x5B8D80"
    },
    "accounts": {
        "0x0000000000000000000000000000000000000001": { "balance": "1", "builtin": { "name": "ecrecover", "pricing": { "linear": { "base": 3000, "word": 0 } } } },
        "0x0000000000000000000000000000000000000002": { "balance": "1", "builtin": { "name": "sha256", "pricing": { "linear": { "base": 60, "word": 12 } } } },
        "0x0000000000000000000000000000000000000003": { "balance": "1", "builtin": { "name": "ripemd160", "pricing": { "linear": { "base": 600, "word": 120 } } } },
        "0x0000000000000000000000000000000000000004": { "balance": "1", "builtin": { "name": "identity", "pricing": { "linear": { "base": 15, "word": 3 } } } }
    }
}

.. config file note0.toml:

[parity]
chain = "custom_chain.json"
base_path = "./"
[network]
port = 30300
[rpc]
port = 8540
apis = ["web3", "eth", "net", "personal", "parity", "parity_set", "traces", "rpc", "parity_accounts"]
[ui]
port = 8180
[websockets]
port = 8450

.. and command:

parity --config node0.toml

Then create two users:

curl --data '{"jsonrpc":"2.0","method":"parity_newAccountFromPhrase","params":["node0", "node0"],"id":0}' -H "Content-Typ e: application/json" -X POST localhost:8540

curl --data '{"jsonrpc":"2.0","method":"parity_newAccountFromPhrase","params":["user", "user"],"id":0}' -H "Content-Typ e: application/json" -X POST localhost:8540

.. and restart node with the following custom_chain.json:

{
    "name": "DemoPoA",
    "engine": {
        "authorityRound": {
            "params": {
                "stepDuration": "5",
                "validators" : {
                    "list": [
                        "0x00Bd138aBD70e2F00903268F3Db08f2D25677C9e"
                    ]
                }
            }
        }
    },
    "params": {
        "gasLimitBoundDivisor": "0x400",
        "maximumExtraDataSize": "0x20",
        "minGasLimit": "0x1388",
        "networkID" : "0x2323"
    },
    "genesis": {
        "seal": {
            "authorityRound": {
                "step": "0x0",
                "signature": "0x0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"
            }
        },
        "difficulty": "0x20000",
        "gasLimit": "0x5B8D80"
    },
    "accounts": {
        "0x0000000000000000000000000000000000000001": { "balance": "1", "builtin": { "name": "ecrecover", "pricing": { "linear": { "base": 3000, "word": 0 } } } },
        "0x0000000000000000000000000000000000000002": { "balance": "1", "builtin": { "name": "sha256", "pricing": { "linear": { "base": 60, "word": 12 } } } },
        "0x0000000000000000000000000000000000000003": { "balance": "1", "builtin": { "name": "ripemd160", "pricing": { "linear": { "base": 600, "word": 120 } } } },
        "0x0000000000000000000000000000000000000004": { "balance": "1", "builtin": { "name": "identity", "pricing": { "linear": { "base": 15, "word": 3 } } } },
        "0x004ec07d2329997267Ec62b4166639513386F32E": { "balance": "10000000000000000000000" }
    }
}

.. node0.toml:

[parity]
chain = "custom_chain.json"
base_path = "./"
[network]
port = 30300
[rpc]
port = 8540
apis = ["web3", "eth", "net", "personal", "parity", "parity_set", "traces", "rpc", "parity_accounts"]
[ui]
port = 8180
[websockets]
port = 8450
[account]
password = ["node.pwds"]
[mining]
engine_signer = "0x00Bd138aBD70e2F00903268F3Db08f2D25677C9e"
reseal_on_txs = "none"

.. node.pwds:

node0

.. and command:

parity --config node0.toml

Then unlock user account:

curl --data '{"method":"personal_unlockAccount","params":["0x004ec07d2329997267Ec62b4166639513386F32E","user",null],"id": 1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST localhost:8540

And try to connect with truffle compile && truffle migrate with the following truffle.js file:

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8540,
      network_id: "0x2323",
      from: "0x004ec07d2329997267Ec62b4166639513386F32E"
    }
  }
};

Expected Behavior

truffle does the initial migration

Actual Results

Hangs forever.

Environment

• Operating System: Windows 10
• Ethereum client: parity1.9.4
• Truffle version (truffle version): 4.3.1
• node version (node --version): 8.1.3
• npm version (npm --version): 4.1.1

P.S. I had similar problem with geth but there I attached to IPC socket and called miner.start() - it helped. Here there is no miner object as there is no PoW (I'm trying to use and need PoA for my dapp).

[cgewecke]

@dmitrysenkovich Does anything in this thread at Parity seem helpful? Towards the end they suggest there is a flag setting for the client that might unstick things:

--reseal-min-period 0

(Also thanks for such a complete description of your setup - really useful for anyone reproducing this.)

[dmitrysenkovich]

@cgewecke thanks for the suggestion but it doesn't help:c

[peara]

@dmitrysenkovich

[mining]
engine_signer = "0x00Bd138aBD70e2F00903268F3Db08f2D25677C9e"
reseal_on_txs = "none"
force_sealing = true

Add the third line to node0.toml. I think it could help.

[cgewecke]

@dmitrysenkovich Did @peara's config suggestion fix this?

[dmitrysenkovich]

@peara, @cgewecke no, that doesn't work too:c now it stucks on {

"jsonrpc": "2.0",
"id": 4,
"method": "eth_sendTransaction",
"params": [
{
"from": "0x004ec07d2329997267Ec62b4166639513386F32E",
"gas": "0x6691b7",
"gasPrice": "0x174876e800",

I'm trying Hyperledger Fabric now, their tutorials seem to be working

[cgewecke]

Ok fair enough @dmitrysenkovich :)

I'm going to close this because it seems like it's specific to parity POA configuration rather than something Truffle related.

As a side note, there's a nice model of parity/truffle integration at colonyNetwork for anyone finding this issue in the course of setting up their project.

[gustin]

I was having the same issue with Parity on a dev chain, after going through a lot of different party configuration, setting the gas and gasPrice explicitly in the truffle.js to a high gas and low gasPrice worked for me.

I'd like to bump this - to this day, we're not able to use Truffle with Parity in POA mode - it hangs forever at the migration step. (/cc @cgewecke)

@hickscorp Is there any way that we can deploy the contract to Parity in POA mode?

[hickscorp]

I don't know, we dropped Parity completely and we are using Geth on our
private network.

@hickscorp Thanks. I will also try Truffle with Geth in POA mode to set up a private network for my dapp.

[a10000005588]

@hickscorp Sorry to bother you again. May I ask you what version of geth, web3 and truffle when you use your Geth in POA mode? Because I ran into an issue: "Uncaught (in promise) Error: Returned values aren't valid, did it run Out of Gas?" After I reviewed the stack overflow, they said it might be the web3.js issue... thanks.
