From e53615b443894fb96d5eb885b3812776c1b1033b Mon Sep 17 00:00:00 2001 From: Andrew Chow Date: Fri, 28 Jul 2017 17:00:49 -0700 Subject: [PATCH] Remove vchDefaultKey and have better first run detection Removes vchDefaultKey which was only used for first run detection. Improves wallet first run detection by checking to see if any keys were read from the database. This will now also check for a valid defaultkey for backwards compatibility reasons and to check for any corruption. Keys will stil be generated on the first one, but there won't be any shown in the address book as was previously done. --- src/wallet/crypter.h | 2 +- src/wallet/wallet.cpp | 26 ++++++++------------------ src/wallet/wallet.h | 4 ---- src/wallet/walletdb.cpp | 17 +++++++++-------- src/wallet/walletdb.h | 2 -- test/functional/keypool-topup.py | 2 +- test/functional/wallet-hd.py | 8 ++++---- 7 files changed, 23 insertions(+), 38 deletions(-) diff --git a/src/wallet/crypter.h b/src/wallet/crypter.h index 1dc44e424..f1e8a2565 100644 --- a/src/wallet/crypter.h +++ b/src/wallet/crypter.h @@ -113,7 +113,6 @@ public: class CCryptoKeyStore : public CBasicKeyStore { private: - CryptedKeyMap mapCryptedKeys; CKeyingMaterial vMasterKey; @@ -131,6 +130,7 @@ protected: bool EncryptKeys(CKeyingMaterial& vMasterKeyIn); bool Unlock(const CKeyingMaterial& vMasterKeyIn); + CryptedKeyMap mapCryptedKeys; public: CCryptoKeyStore() : fUseCrypto(false), fDecryptionThoroughlyChecked(false) diff --git a/src/wallet/wallet.cpp b/src/wallet/wallet.cpp index 599e74149..ea436b413 100644 --- a/src/wallet/wallet.cpp +++ b/src/wallet/wallet.cpp @@ -3114,9 +3114,11 @@ DBErrors CWallet::LoadWallet(bool& fFirstRunRet) } } + // This wallet is in its first run if all of these are empty + fFirstRunRet = mapKeys.empty() && mapCryptedKeys.empty() && mapWatchKeys.empty() && setWatchOnly.empty() && mapScripts.empty(); + if (nLoadWalletRet != DB_LOAD_OK) return nLoadWalletRet; - fFirstRunRet = !vchDefaultKey.IsValid(); uiInterface.LoadWallet(this); @@ -3126,7 +3128,6 @@ DBErrors CWallet::LoadWallet(bool& fFirstRunRet) DBErrors CWallet::ZapSelectTx(std::vector& vHashIn, std::vector& vHashOut) { AssertLockHeld(cs_wallet); // mapWallet - vchDefaultKey = CPubKey(); DBErrors nZapSelectTxRet = CWalletDB(*dbw,"cr+").ZapSelectTx(vHashIn, vHashOut); for (uint256 hash : vHashOut) mapWallet.erase(hash); @@ -3155,7 +3156,6 @@ DBErrors CWallet::ZapSelectTx(std::vector& vHashIn, std::vector& vWtx) { - vchDefaultKey = CPubKey(); DBErrors nZapWalletTxRet = CWalletDB(*dbw,"cr+").ZapWalletTx(vWtx); if (nZapWalletTxRet == DB_NEED_REWRITE) { @@ -3231,14 +3231,6 @@ const std::string& CWallet::GetAccountName(const CScript& scriptPubKey) const return DEFAULT_ACCOUNT_NAME; } -bool CWallet::SetDefaultKey(const CPubKey &vchPubKey) -{ - if (!CWalletDB(*dbw).WriteDefaultKey(vchPubKey)) - return false; - vchDefaultKey = vchPubKey; - return true; -} - /** * Mark old keypool keys as used, * and generate all new keys @@ -4014,13 +4006,11 @@ CWallet* CWallet::CreateWalletFromFile(const std::string walletFile) if (!walletInstance->SetHDMasterKey(masterPubKey)) throw std::runtime_error(std::string(__func__) + ": Storing master key failed"); } - CPubKey newDefaultKey; - if (walletInstance->GetKeyFromPool(newDefaultKey, false)) { - walletInstance->SetDefaultKey(newDefaultKey); - if (!walletInstance->SetAddressBook(walletInstance->vchDefaultKey.GetID(), "", "receive")) { - InitError(_("Cannot write default address") += "\n"); - return nullptr; - } + + // Top up the keypool + if (!walletInstance->TopUpKeyPool()) { + InitError(_("Unable to generate initial keys") += "\n"); + return NULL; } walletInstance->SetBestChain(chainActive.GetLocator()); diff --git a/src/wallet/wallet.h b/src/wallet/wallet.h index f97a99d82..d79edbb11 100644 --- a/src/wallet/wallet.h +++ b/src/wallet/wallet.h @@ -807,8 +807,6 @@ public: std::map mapAddressBook; - CPubKey vchDefaultKey; - std::set setLockedCoins; const CWalletTx* GetWalletTx(const uint256& hash) const; @@ -1040,8 +1038,6 @@ public: return setInternalKeyPool.size() + setExternalKeyPool.size(); } - bool SetDefaultKey(const CPubKey &vchPubKey); - //!
