Error parsing bitcoin testnet transaction #365

Closed bit0t closed 10 months ago

bit0t commented 10 months ago

the library (v. 0.6.12) throws the following error while parsing the following raw transaction:

Traceback (most recent call last): File "XXXX", line 577, in _fetch_tx_coro parsed_resp = Transaction.parse_hex(resp, network=self.network, strict=False) File "/venv/lib/python3.10/site-packages/bitcoinlib/transactions.py", line 1545, in parse_hex return cls.parse_bytesio(BytesIO(bytes.fromhex(rawtx)), strict, network) File "/venv/lib/python3.10/site-packages/bitcoinlib/transactions.py", line 1501, in parse_bytesio if script.script_types[0][:13] == 'p2sh_multisig' or script.script_types[0] =='signature_multisig': IndexError: list index out of range

The last input of the transaction contains an witness script with an incorrect size. However this shouldn't lead to errors when using strict=False. Fixed in commit https://github.com/1200wd/bitcoinlib/commit/1454d578765bfa684491a7d90b42448706c29895
