From 7d8ffac18612fe9a5faea3f8fb41442f9e7a3c1d Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Sat, 6 Jun 2015 09:41:12 +0200 Subject: [PATCH] Changes necessary now that zero values accepted in AmountFromValue - Add an accept test for zero amounts, and a reject test for negative amounts - Remove ugly hack in `settxfee` that is no longer necessary - Do explicit zero checks in wallet RPC functions - Don't add a check for zero amounts in `createrawtransaction` - this could be seen as a feature --- src/test/rpc_tests.cpp | 3 +++ src/wallet/rpcwallet.cpp | 14 ++++++++++---- 2 files changed, 13 insertions(+), 4 deletions(-) diff --git a/src/test/rpc_tests.cpp b/src/test/rpc_tests.cpp index 0b33ddb08..08f988fdb 100644 --- a/src/test/rpc_tests.cpp +++ b/src/test/rpc_tests.cpp @@ -131,6 +131,9 @@ static UniValue ValueFromString(const std::string &str) BOOST_AUTO_TEST_CASE(rpc_parse_monetary_values) { + BOOST_CHECK_THROW(AmountFromValue(ValueFromString("-0.00000001")), UniValue); + BOOST_CHECK_EQUAL(AmountFromValue(ValueFromString("0")), 0LL); + BOOST_CHECK_EQUAL(AmountFromValue(ValueFromString("0.00000000")), 0LL); BOOST_CHECK_EQUAL(AmountFromValue(ValueFromString("0.00000001")), 1LL); BOOST_CHECK_EQUAL(AmountFromValue(ValueFromString("0.17622195")), 17622195LL); BOOST_CHECK_EQUAL(AmountFromValue(ValueFromString("0.5")), 50000000LL); diff --git a/src/wallet/rpcwallet.cpp b/src/wallet/rpcwallet.cpp index e44940993..d284fcf15 100644 --- a/src/wallet/rpcwallet.cpp +++ b/src/wallet/rpcwallet.cpp @@ -414,6 +414,8 @@ UniValue sendtoaddress(const UniValue& params, bool fHelp) // Amount CAmount nAmount = AmountFromValue(params[1]); + if (nAmount <= 0) + throw JSONRPCError(RPC_TYPE_ERROR, "Invalid amount for send"); // Wallet comments CWalletTx wtx; @@ -809,6 +811,8 @@ UniValue movecmd(const UniValue& params, bool fHelp) string strFrom = AccountFromValue(params[0]); string strTo = AccountFromValue(params[1]); CAmount nAmount = AmountFromValue(params[2]); + if (nAmount <= 0) + throw JSONRPCError(RPC_TYPE_ERROR, "Invalid amount for send"); if (params.size() > 3) // unused parameter, used to be nMinDepth, keep type-checking it though (void)params[3].get_int(); @@ -888,6 +892,8 @@ UniValue sendfrom(const UniValue& params, bool fHelp) if (!address.IsValid()) throw JSONRPCError(RPC_INVALID_ADDRESS_OR_KEY, "Invalid Bitcoin address"); CAmount nAmount = AmountFromValue(params[2]); + if (nAmount <= 0) + throw JSONRPCError(RPC_TYPE_ERROR, "Invalid amount for send"); int nMinDepth = 1; if (params.size() > 3) nMinDepth = params[3].get_int(); @@ -987,6 +993,8 @@ UniValue sendmany(const UniValue& params, bool fHelp) CScript scriptPubKey = GetScriptForDestination(address.Get()); CAmount nAmount = AmountFromValue(sendTo[name_]); + if (nAmount <= 0) + throw JSONRPCError(RPC_TYPE_ERROR, "Invalid amount for send"); totalAmount += nAmount; bool fSubtractFeeFromAmount = false; @@ -2168,9 +2176,7 @@ UniValue settxfee(const UniValue& params, bool fHelp) LOCK2(cs_main, pwalletMain->cs_wallet); // Amount - CAmount nAmount = 0; - if (params[0].get_real() != 0.0) - nAmount = AmountFromValue(params[0]); // rejects 0.0 amounts + CAmount nAmount = AmountFromValue(params[0]); payTxFee = CFeeRate(nAmount, 1000); return true; @@ -2352,4 +2358,4 @@ UniValue listunspent(const UniValue& params, bool fHelp) } return results; -} \ No newline at end of file +}
