From 066e2a1403fe306787a2ce0c8571aa9de57386cf Mon Sep 17 00:00:00 2001 From: Cory Fields Date: Wed, 24 Sep 2014 22:24:46 -0400 Subject: script: move CScriptID to standard.h and add a ctor for creating them from CScripts This allows for a reversal of the current behavior. This: CScript foo; CScriptID bar(foo.GetID()); Becomes: CScript foo; CScriptID bar(foo); This way, CScript is no longer dependent on CScriptID or Hash(); --- src/crypter.cpp | 1 + src/key.h | 8 -------- src/keystore.cpp | 3 ++- src/keystore.h | 1 + src/rpcmisc.cpp | 2 +- src/rpcrawtransaction.cpp | 2 +- src/rpcwallet.cpp | 2 +- src/script/compressor.cpp | 1 + src/script/compressor.h | 2 ++ src/script/script.h | 6 ------ src/script/standard.cpp | 2 ++ src/script/standard.h | 9 +++++++++ src/test/miner_tests.cpp | 2 +- src/test/script_P2SH_tests.cpp | 20 ++++++++++---------- src/test/script_tests.cpp | 4 ++-- src/test/sigopcount_tests.cpp | 4 ++-- src/wallet.cpp | 2 +- 17 files changed, 37 insertions(+), 34 deletions(-) diff --git a/src/crypter.cpp b/src/crypter.cpp index a872df7024..756538836d 100644 --- a/src/crypter.cpp +++ b/src/crypter.cpp @@ -5,6 +5,7 @@ #include "crypter.h" #include "script/script.h" +#include "script/standard.h" #include "util.h" #include diff --git a/src/key.h b/src/key.h index f6f6d35d34..48b1652536 100644 --- a/src/key.h +++ b/src/key.h @@ -30,14 +30,6 @@ public: CKeyID(const uint160& in) : uint160(in) {} }; -/** A reference to a CScript: the Hash160 of its serialization (see script.h) */ -class CScriptID : public uint160 -{ -public: - CScriptID() : uint160(0) {} - CScriptID(const uint160& in) : uint160(in) {} -}; - /** An encapsulated public key. */ class CPubKey { diff --git a/src/keystore.cpp b/src/keystore.cpp index 755defa26d..039c690625 100644 --- a/src/keystore.cpp +++ b/src/keystore.cpp @@ -8,6 +8,7 @@ #include "crypter.h" #include "key.h" #include "script/script.h" +#include "script/standard.h" #include "util.h" #include @@ -38,7 +39,7 @@ bool CBasicKeyStore::AddCScript(const CScript& redeemScript) return error("CBasicKeyStore::AddCScript() : redeemScripts > %i bytes are invalid", MAX_SCRIPT_ELEMENT_SIZE); LOCK(cs_KeyStore); - mapScripts[redeemScript.GetID()] = redeemScript; + mapScripts[CScriptID(redeemScript)] = redeemScript; return true; } diff --git a/src/keystore.h b/src/keystore.h index d3478f7672..4f8189c8f5 100644 --- a/src/keystore.h +++ b/src/keystore.h @@ -13,6 +13,7 @@ #include class CScript; +class CScriptID; /** A virtual base class for key stores */ class CKeyStore diff --git a/src/rpcmisc.cpp b/src/rpcmisc.cpp index 8be14b567c..92ed1c3e2b 100644 --- a/src/rpcmisc.cpp +++ b/src/rpcmisc.cpp @@ -292,7 +292,7 @@ Value createmultisig(const Array& params, bool fHelp) // Construct using pay-to-script-hash: CScript inner = _createmultisig_redeemScript(params); - CScriptID innerID = inner.GetID(); + CScriptID innerID(inner); CBitcoinAddress address(innerID); Object result; diff --git a/src/rpcrawtransaction.cpp b/src/rpcrawtransaction.cpp index 78372da685..fdfcb59eeb 100644 --- a/src/rpcrawtransaction.cpp +++ b/src/rpcrawtransaction.cpp @@ -480,7 +480,7 @@ Value decodescript(const Array& params, bool fHelp) } ScriptPubKeyToJSON(script, r, false); - r.push_back(Pair("p2sh", CBitcoinAddress(script.GetID()).ToString())); + r.push_back(Pair("p2sh", CBitcoinAddress(CScriptID(script)).ToString())); return r; } diff --git a/src/rpcwallet.cpp b/src/rpcwallet.cpp index d11455e389..68bb4068b8 100644 --- a/src/rpcwallet.cpp +++ b/src/rpcwallet.cpp @@ -918,7 +918,7 @@ Value addmultisigaddress(const Array& params, bool fHelp) // Construct using pay-to-script-hash: CScript inner = _createmultisig_redeemScript(params); - CScriptID innerID = inner.GetID(); + CScriptID innerID(inner); pwalletMain->AddCScript(inner); pwalletMain->SetAddressBook(innerID, strAccount, "send"); diff --git a/src/script/compressor.cpp b/src/script/compressor.cpp index 51a3cf6025..dbb4df8b7c 100644 --- a/src/script/compressor.cpp +++ b/src/script/compressor.cpp @@ -4,6 +4,7 @@ // file COPYING or http://www.opensource.org/licenses/mit-license.php. #include "compressor.h" +#include "script/standard.h" bool CScriptCompressor::IsToKeyID(CKeyID &hash) const { diff --git a/src/script/compressor.h b/src/script/compressor.h index 53c6bf3ecc..f48ecf5001 100644 --- a/src/script/compressor.h +++ b/src/script/compressor.h @@ -8,6 +8,8 @@ #include "script/script.h" +class CScriptID; + /** Compact serializer for scripts. * * It detects common cases and encodes them much more efficiently. diff --git a/src/script/script.h b/src/script/script.h index caf176476f..4d685f5596 100644 --- a/src/script/script.h +++ b/src/script/script.h @@ -610,12 +610,6 @@ public: } return str; } - - CScriptID GetID() const - { - return CScriptID(Hash160(*this)); - } - void clear() { // The default std::vector::clear() does not release memory. diff --git a/src/script/standard.cpp b/src/script/standard.cpp index 53ae254d59..adbec01f2e 100644 --- a/src/script/standard.cpp +++ b/src/script/standard.cpp @@ -14,6 +14,8 @@ using namespace std; typedef vector valtype; +CScriptID::CScriptID(const CScript& in) : uint160(in.size() ?
