No connection with local bitcoin node

[yoprogramo]

Hello,

I have installed a full bitcoin node (testnet) in a machine inside my local network, I have configurard inside providers.json as:

  "bitcoind.testnet": {
    "provider": "bitcoind",
    "network": "testnet",
    "client_class": "BitcoindClient",
    "url": "http://user:pass@172.18.0.48:18332",
    "api_key": "",
    "priority": 11,
    "denominator": 100000000
  }

When I execute the example, it works fine and I' able to see the rpc calls in the debug log of the node

>>> from bitcoinlib.services.bitcoind import BitcoindClient
>>> base_url = 'http://user:pass@172.18.0.48:18332'
>>> bdc = BitcoindClient(base_url=base_url)
>>> txid='5be96332d5dcaeae72e3f81e69230ccc50cf1eb172850dbf1fcaa55f1f6b9c99'
>>> rt = bdc.getrawtransaction(txid)
>>> print("Raw: %s" % rt)
Raw: 02000000000101dfc42faee33ddada2543639df664972878376605e386905a0d8d201389fb21140000000000fdffffff02fb7977f701000000160014e6addae37027ce8d2825ec7e959f2f246ed275e82ab0180000000000160014382f5ef14a13eb00e9cd7b496543f09464616e870247304402207147aab1d21994702a4258f5cba6529ab1e8afbf47ccb88eff3846f6c49f67f50220145f58c6ce7e828dd834de68988c42998929fed1ab673e69fe24034f542f26640121036dd1be65e183f9b0e84bc5fa324cd90894773909118028494b5c9338bed2c928d6c32600

debug.log:

2023-11-27T07:27:53Z [rpc] ThreadRPCServer method=getrawtransaction user=user

BUT when I use wallets and update the utxo's (for example) there are not rpc log... How can I force the use of this node?

You can specify which providers to use by setting the providers attribute of the Wallet object.

w = wallet_create_or_open('testwallet)
w.providers = ['bitcoind']

Thanks a lot, it seems to be the correct answer, but I have some problem when I try. Using the same configuration as the initial message:

>>> from bitcoinlib.wallets import Wallet
>>> wallet = Wallet('wallet-1701164965.069888')
>>> wallet.providers = ['bitcoind']
>>> wallet.utxos_update()
Traceback (most recent call last):

  File "/home/espinosa/.local/share/virtualenvs/btc-service-4yQJ9tbx/lib/python3.10/site-packages/bitcoinlib/services/services.py", line 224, in _provider_execute
    raise ServiceError("No successful response from any serviceprovider: %s" % list(self.providers.keys()))
bitcoinlib.services.services.ServiceError: No successful response from any serviceprovider: ['bitcoind.testnet']

There is some other configuration to take into account regarding full nodes?

[mccwdev]

The error from bitcoind itself is not visible here. Maybe you can find more info in bitcoinlib.log? You might need to lower the loglevel to DEBUG in .bitcoinlib/config.ini

As far as I can see, your configuration looks correct to me.

[yoprogramo]

I modified the config.ini for debug and the firs error message was:

2023/11/29 22:02:33 DEBUG _provider_execute(207) Error 'provider_coin_id' on provider bitcoind.testnet

I fill provider_coin_id with "", then I received this:

2023/11/29 22:20:50 DEBUG _provider_execute(207) Error 'network_overrides' on provider bitcoind.testnet

I fill this field with null (as the others in providers.json) an then

2023/11/29 22:21:49 DEBUG _provider_execute(207) Error BitcoindClient.__init__() takes from 1 to 4 positional arguments but 10 were given on provider bitcoind.testnet

I'll make more tests ...

[yoprogramo]

Comparing the BitcoindClient with other providers I see that this uses kwargs

  def __init__(self, network='bitcoin', base_url='', denominator=100000000, **kwargs):

That expect named parameters and others use args (positional ones)

BcoinClient, BitGoClient:

def __init__(self, network, base_url, denominator, *args):

Can this be the problem?

I suggest a solution in the pull request #352
