There was a problem hiding this comment.
ACK faf37c2
This change adds a "desc" field that was missing from the "witness_utxo" decodepsbt inputs help and IIUC removes undocumented "desc" descriptor fields from the decodepsbt inputs and outputs "redeem_script" and "witness_script" result objects.
Code review:
ScriptPubKeyToUniv() is declared with include_address = true by default
src/core_io.h:56:void ScriptPubKeyToUniv(const CScript& scriptPubKey, UniValue& out, bool include_hex, bool include_address = true);and is invoked once in decodepsbt in the witness inputs code
// inputs
CAmount total_in = 0;
bool have_all_utxos = true;
UniValue inputs(UniValue::VARR);
for (unsigned int i = 0; i < psbtx.inputs.size(); ++i) {
const PSBTInput& input = psbtx.inputs[i];
UniValue in(UniValue::VOBJ);
// UTXOs
bool have_a_utxo = false;
CTxOut txout;
if (!input.witness_utxo.IsNull()) {
txout = input.witness_utxo;
UniValue o(UniValue::VOBJ);
ScriptPubKeyToUniv(txout.scriptPubKey, o, /* include_hex */ true);
UniValue out(UniValue::VOBJ);
out.pushKV("amount", ValueFromAmount(txout.nValue));
out.pushKV("scriptPubKey", o);
in.pushKV("witness_utxo", out);
have_a_utxo = true;
}relevant updated decodepsbt help
"inputs" : [ (json array)
{ (json object)
"non_witness_utxo" : { (json object, optional) Decoded network transaction for non-witness UTXOs
...
},
"witness_utxo" : { (json object, optional) Transaction output for witness UTXOs
"amount" : n, (numeric) The value in BTC
"scriptPubKey" : { (json object)
"asm" : "str", (string) The asm
"desc" : "str", (string) Inferred descriptor for the output
"hex" : "hex", (string) The hex
"type" : "str", (string) The type, eg 'pubkeyhash'
"address" : "str" (string, optional) The Bitcoin address (only if a well-defined address exists)
}
OTOH ScriptToUniv() is the only caller to invoke ScriptPubKeyToUniv() with include_address = false, and outside of a fuzz test is only called in decodepsbt inputs and outputs "redeem_script" and "witness_script" result code and so with this pull the descriptor will be excluded
void ScriptToUniv(const CScript& script, UniValue& out)
{
ScriptPubKeyToUniv(script, out, /* include_hex */ true, /* include_address */ false);
}

Fix this by excluding them when it doesn't make sense. This should only affect the `decodepsbt` RPC.
