From d6117cd5887801142867a0cd87f9e1260ff02a8e Mon Sep 17 00:00:00 2001 From: Djuri Baars Date: Mon, 8 Jun 2026 16:28:51 +0200 Subject: [PATCH 01/13] Implement bitcoind JSON-RPC blockchain query methods. getblock (verbosity 1/2), getblockcount, getblockhash, getblockheader, getblockchaininfo, getblockfilter, gettxout and getnetworkinfo, reusing the libbitcoin-system bitcoind json serializers with a protocol-level context injector (height, confirmations, mediantime, prev/next hash). Aggregate-heavy methods (getchainwork, getchaintxstats, getblockstats, gettxoutsetinfo, scantxoutset, verifychain, verifytxoutset, pruneblockchain, savemempool) remain explicit not_implemented. --- .../bitcoind/protocol_bitcoind_rpc.cpp | 308 ++++++++++++++++-- 1 file changed, 283 insertions(+), 25 deletions(-) diff --git a/src/protocols/bitcoind/protocol_bitcoind_rpc.cpp b/src/protocols/bitcoind/protocol_bitcoind_rpc.cpp index 2961185f..79e8f522 100644 --- a/src/protocols/bitcoind/protocol_bitcoind_rpc.cpp +++ b/src/protocols/bitcoind/protocol_bitcoind_rpc.cpp @@ -18,8 +18,11 @@ */ #include +#include +#include #include #include +#include namespace libbitcoin { namespace server { @@ -160,6 +163,93 @@ std::string to_hex(const Object& object, size_t size, Args&&... args) NOEXCEPT return out;

Extend the REST interface beyond block: block_hash (blockhashbyheight), block_txs (notxdetails), block_headers, block_part, block_spent_tx_outputs, block_filter, block_filter_headers and chain_information, with their Core REST url patterns parsed in bitcoind_target. Remaining endpoints (get_utxos[_confirmed], mempool[_information], fork_information) need mempool enumeration / deployment status / utxo semantics not yet exposed, so are left unimplemented. --- .../protocols/protocol_bitcoind_rest.hpp | 19 + src/parsers/bitcoind_target.cpp | 166 ++++++- .../bitcoind/protocol_bitcoind_rest.cpp | 456 ++++++++++++++++++ 3 files changed, 634 insertions(+), 7 deletions(-) diff --git a/include/bitcoin/server/protocols/protocol_bitcoind_rest.hpp b/include/bitcoin/server/protocols/protocol_bitcoind_rest.hpp index 00eef7e6..e859bc11 100644 --- a/include/bitcoin/server/protocols/protocol_bitcoind_rest.hpp +++ b/include/bitcoin/server/protocols/protocol_bitcoind_rest.hpp @@ -58,6 +58,25 @@ class BCS_API protocol_bitcoind_rest /// REST interface handlers. bool handle_get_block(const code& ec, rest_interface::block, uint8_t media, system::hash_cptr hash) NOEXCEPT; + bool handle_get_block_hash(const code& ec, rest_interface::block_hash, + uint8_t media, uint32_t height) NOEXCEPT; + bool handle_get_block_txs(const code& ec, rest_interface::block_txs, + uint8_t media, system::hash_cptr hash) NOEXCEPT; + bool handle_get_block_headers(const code& ec, rest_interface::block_headers, + uint8_t media, system::hash_cptr hash, uint32_t count) NOEXCEPT; + bool handle_get_block_part(const code& ec, rest_interface::block_part, + uint8_t media, system::hash_cptr hash, uint32_t offset, + uint32_t size) NOEXCEPT; + bool handle_get_block_spent_tx_outputs(const code& ec, + rest_interface::block_spent_tx_outputs, uint8_t media, + system::hash_cptr hash) NOEXCEPT; + bool handle_get_block_filter(const code& ec, rest_interface::block_filter, + uint8_t media, system::hash_cptr hash, uint8_t type) NOEXCEPT; + bool handle_get_block_filter_headers(const code& ec, + rest_interface::block_filter_headers, uint8_t media, + system::hash_cptr hash, uint8_t type) NOEXCEPT; + bool handle_get_chain_information(const code& ec, + rest_interface::chain_information) NOEXCEPT; /// REST raw-http response senders (not json-rpc enveloped). void send_data(system::data_chunk&& bytes) NOEXCEPT; diff --git a/src/parsers/bitcoind_target.cpp b/src/parsers/bitcoind_target.cpp index 31575ef6..3384921d 100644 --- a/src/parsers/bitcoind_target.cpp +++ b/src/parsers/bitcoind_target.cpp @@ -62,9 +62,29 @@ static bool to_media(uint8_t& out, const std::string_view& extension) NOEXCEPT return false; } +template +static bool to_number(Number& out, const std::string_view& token) NOEXCEPT +{ + return !token.empty() && is_ascii_numeric(token) && (is_one(token.size()) || + token.front() != '0') && deserialize(out, token); +} + +// Split a "." leaf into its name and a media value. +static bool split_leaf(std::string& name, uint8_t& media, + const std::string_view& leaf) NOEXCEPT +{ + const auto parts = split(leaf, ".", false, true); + if (parts.size() != two) + return false; + + name = parts.front(); + return to_media(media, parts.back()); +} + // Parse a Bitcoin Core REST path into a json-rpc request model. // github.com/bitcoin/bitcoin/blob/master/doc/REST-interface.md -// Currently supports: /rest/block/. +// Supports: block, block/notxdetails, blockhashbyheight, headers, blockpart, +// chaininfo (remaining endpoints return invalid_target until implemented). code bitcoind_target(request_t& out, const std::string_view& path) NOEXCEPT { const auto clean = split(path, "?", false, false).front(); @@ -98,27 +118,159 @@ code bitcoind_target(request_t& out, const std::string_view& path) NOEXCEPT return error::missing_target; const auto target = segments[segment++]; + + // /rest/chaininfo.json + if (target == "chaininfo" || target == "chaininfo.json") + { + method = "chain_information"; + return error::success; + } + + // /rest/block/., /rest/block/notxdetails/. and + // /rest/block/spent/.

Cross-checked all declared bitcoind signatures against Core's RPCMethod definitions (bitcoin/bitcoin src/rpc). Two fixes: - getblockstats: hash_or_height was declared string_t, but Core accepts a height number OR a block hash (RPCArg::Type::NUM with skip_type_check). A numeric height threw 'unexpected type' at dispatch. Declare as value_t (the dispatcher passes it through untyped), matching Core; verified both a numeric height and a hash now reach the handler. - getrawtransaction: param named 'verbose'; Core's canonical name is 'verbosity' (with 'verbose' as an alias), and getblock already uses 'verbosity'.

Boost.Test, in-build, no external dependencies, per the libbitcoin test taxonomy (unit = lowest-level function, component = aggregate over a class). Unit (test/parsers/bitcoind_target.cpp, replacing the stub): cover the pure bitcoind_target() REST path parser across every route and error path (media mapping, missing/invalid target/hash/number, leading-zero, non-basic filter); error and media cases are data-driven. Unit + component (test/protocols/bitcoind/bitcoind_json.cpp, new): pure header_to_bitcoind field mapping, plus chain_name, median_time_past (BIP113), inject_block_context (genesis/middle/tip) and inject_tx_context (confirmed/unknown) against the ten-block mock store via a minimal store+query fixture (no server/socket).

Relocate the bitcoind json context helpers out of the inline header (bitcoind_json.hpp) into protocol_bitcoind_rpc as protected static methods, implemented in protocol_bitcoind_rpc_json.cpp and inherited by the rest protocol. Removes them from the broad server namespace and keeps the implementation out of headers. chain_name now derives each network's genesis from system::settings (per the chain::selection enumeration) rather than hardcoded hashes; signet remains a documented stub pending its selection. Source idiom: pass hash_cptr by const& in the rest handlers (native/electrum convention), use to_shared(std::move()) and std::from_chars() in the target parser. Tests: bitcoind_target gains real coverage, bitcoind_json exercises the helpers via a test seam; rest_text() strips line terminators, display hashes are computed once at file scope, header bytes are hashed directly, and the verbose comments are dropped.
