From 4c5e24414e71bcf303a92733d710e8d251083e87 Mon Sep 17 00:00:00 2001 From: +Sharon <+wanjiku.kahira@gmail.com> Date: Fri, 11 Jul 2025 12:01:47 +0300 Subject: [PATCH 1/2] Add `DecodeScriptSegwit` struct and support in `DecodeScript` conversion - Add `DecodeScriptSegwit` struct to model the `segwit` field returned by the `decodescript` RPC. - Update `DecodeScript` to include an optional `segwit` field. - Add `raw_transactions`folder to v19. Add DecodeScriptSegwit struct, conversions, and model support - Add `DecodeScriptSegwit` struct to both versioned and model representations. - Implement `into_model()` for `DecodeScriptSegwit` and update `DecodeScript` accordingly. - Use `ScriptBuf` instead of `String` for `hex` to strongly type the field. - Replace `String` with `Address` for `p2sh_segwit` and other fields. - Normalize and correct field comments to match Core `decodescript` RPC output. - Clean up formatting errors Add DecodeScriptSegwit into_model to v17 and refactor error handling - Add `into_model` implementation for `DecodeScriptSegwit` in v17. - Return `segwit` in v17, as it is present in RPC output despite not being documented until v19. - Add `DecodeScriptSegwitError` enum in v17, as `address` is sometimes `None` and error handling is needed. - Remove duplicate `DecodeScriptSegwitError` from v23 and reuse the one from v22 via import. - Move `descriptor` field in `DecodeScriptSegwit` model struct to match the field order in Bitcoin Core's `decodescript` RPC response. Add model test for decode_script with P2WPKH SegWit output Add model test for decode_script_segwit inyo model --- integration_test/tests/raw_transactions.rs | 170 +++++++++++++++++++-- types/src/model/mod.rs | 9 +- types/src/model/raw_transactions.rs | 25 ++- types/src/v17/raw_transactions/error.rs | 46 +++++- types/src/v17/raw_transactions/into.rs | 42 ++++- types/src/v17/raw_transactions/mod.rs | 20 ++- types/src/v19/mod.rs | 7 +- types/src/v19/raw_transactions/error.rs | 83 ++++++++++ types/src/v19/raw_transactions/into.rs | 73 +++++++++ types/src/v19/raw_transactions/mod.rs | 66 ++++++++ types/src/v22/mod.rs | 5 +- types/src/v22/raw_transactions/error.rs | 25 +-- types/src/v22/raw_transactions/into.rs | 41 ++++- types/src/v22/raw_transactions/mod.rs | 25 ++- types/src/v23/mod.rs | 4 +- types/src/v23/raw_transactions/error.rs | 24 +-- types/src/v23/raw_transactions/into.rs | 39 ++++- types/src/v23/raw_transactions/mod.rs | 31 ++-- 18 files changed, 633 insertions(+), 102 deletions(-) create mode 100644 types/src/v19/raw_transactions/error.rs create mode 100644 types/src/v19/raw_transactions/into.rs create mode 100644 types/src/v19/raw_transactions/mod.rs diff --git a/integration_test/tests/raw_transactions.rs b/integration_test/tests/raw_transactions.rs index 90c286e1..134e1090 100644 --- a/integration_test/tests/raw_transactions.rs +++ b/integration_test/tests/raw_transactions.rs @@ -4,16 +4,21 @@ #![allow(non_snake_case)] // Test names intentionally use double underscore. #![allow(unused_imports)] // Because of feature gated tests. - +use bitcoin::address::NetworkUnchecked; use bitcoin::consensus::encode; +use bitcoin::hashes::{hash160, sha256, Hash}; use bitcoin::hex::FromHex as _; +use bitcoin::key::{Secp256k1, XOnlyPublicKey}; use bitcoin::opcodes::all::*; +use bitcoin::script::Builder; use bitcoin::{ - absolute, consensus, hex, psbt, script, transaction, Amount, ScriptBuf, Transaction, TxOut, + absolute, consensus, hex, psbt, script, secp256k1, transaction, Address, Amount, Network, + PublicKey, ScriptBuf, Transaction, TxOut, WPubkeyHash, WScriptHash, }; use integration_test::{Node, NodeExt as _, Wallet}; use node::vtype::*; use node::{mtype, Input, Output}; // All the version specific types. +use rand::Rng; #[test] #[cfg(not(feature = "v17"))] // analyzepsbt was added in v0.18. @@ -196,24 +201,72 @@ fn raw_transactions__decode_raw_transaction__modelled() { } #[test] -// FIXME: Seems the returned fields are different depending on the script.

Add DecodeScriptSegwit struct, conversions, and model support - Add `DecodeScriptSegwit` struct to both versioned and model representations. - Implement `into_model()` for `DecodeScriptSegwit` and update `DecodeScript` accordingly. - Use `ScriptBuf` instead of `String` for `hex` to strongly type the field. - Replace `String` with `Address` for `p2sh_segwit` and other fields. - Normalize and correct field comments to match Core `decodescript` RPC output. - Clean up formatting errors Add DecodeScriptSegwit into_model to v17 and refactor error handling - Add `into_model` implementation for `DecodeScriptSegwit` in v17. - Return `segwit` in v17, as it is present in RPC output despite not being documented until v19. - Add `DecodeScriptSegwitError` enum in v17, as `address` is sometimes `None` and error handling is needed. - Remove duplicate `DecodeScriptSegwitError` from v23 and reuse the one from v22 via import. - Move `descriptor` field in `DecodeScriptSegwit` model struct to match the field order in Bitcoin Core's `decodescript` RPC response.
