From 6919c823cbce92248647880fb1d912828449ae57 Mon Sep 17 00:00:00 2001 From: Russell Yanofsky Date: Tue, 31 Aug 2021 09:59:12 -0400 Subject: [PATCH] MOVEONLY: Expose BanMapToJson / BanMapFromJson CSubNet serialization code that was removed in fa4e6afdae7b82df638b60edf37ac36d57a8cb4f was needed by multiprocess code to share ban map between gui and node processes. Rather than adding it back, use suggestion from MarcoFalke https://github.com/bitcoin/bitcoin/pull/10102#discussion_r690922929 to use JSON serialization. This requires making BanMapToJson / BanMapFromJson functions public. --- src/Makefile.am | 1 + src/addrdb.cpp | 57 ----------------------------------------- src/addrdb.h | 27 -------------------- src/net_types.cpp | 65 +++++++++++++++++++++++++++++++++++++++++++++++ src/net_types.h | 47 +++++++++++++++++++++++++++++++++- 5 files changed, 112 insertions(+), 85 deletions(-) create mode 100644 src/net_types.cpp diff --git a/src/Makefile.am b/src/Makefile.am index a8d6591e98b..6f8245de8a0 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -548,6 +548,7 @@ libbitcoin_common_a_SOURCES = \ key.cpp \ key_io.cpp \ merkleblock.cpp \ + net_types.cpp \ netaddress.cpp \ netbase.cpp \ net_permissions.cpp \ diff --git a/src/addrdb.cpp b/src/addrdb.cpp index a5383be7cf7..345dbdfb164 100644 --- a/src/addrdb.cpp +++ b/src/addrdb.cpp @@ -19,64 +19,7 @@ #include #include -CBanEntry::CBanEntry(const UniValue& json) - : nVersion(json["version"].get_int()), nCreateTime(json["ban_created"].get_int64()), - nBanUntil(json["banned_until"].get_int64()) -{ -} - -UniValue CBanEntry::ToJson() const -{ - UniValue json(UniValue::VOBJ); - json.pushKV("version", nVersion); - json.pushKV("ban_created", nCreateTime); - json.pushKV("banned_until", nBanUntil); - return json; -} - namespace { - -static const char* BANMAN_JSON_ADDR_KEY = "address"; - -/** - * Convert a `banmap_t` object to a JSON array. - * @param[in] bans Bans list to convert. - * @return a JSON array, similar to the one returned by the `listbanned` RPC.
