From 535203075e50eedef8f00852328f81f440233278 Mon Sep 17 00:00:00 2001 From: Russell Yanofsky Date: Wed, 31 Oct 2018 13:00:54 -0400 Subject: Avoid using numeric_limits for sequence numbers and lock times Switches to named constants, because numeric_limits calls can be harder to read and less portable. Change was suggested by James O'Beirne in https://github.com/bitcoin/bitcoin/pull/10973#discussion_r213473620 There are no changes in behavior except on some platforms we don't support (ILP64, IP16L32, I16LP32), where SignalsOptInRBF() and MutateTxAddInput() functions would now work correctly. --- src/rpc/rawtransaction.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'src/rpc/rawtransaction.cpp') diff --git a/src/rpc/rawtransaction.cpp b/src/rpc/rawtransaction.cpp index a2d990b51d..bcc4db963c 100644 --- a/src/rpc/rawtransaction.cpp +++ b/src/rpc/rawtransaction.cpp @@ -346,7 +346,7 @@ CMutableTransaction ConstructTransaction(const UniValue& inputs_in, const UniVal if (!locktime.isNull()) { int64_t nLockTime = locktime.get_int64(); - if (nLockTime < 0 || nLockTime > std::numeric_limits::max()) + if (nLockTime < 0 || nLockTime > LOCKTIME_MAX) throw JSONRPCError(RPC_INVALID_PARAMETER, "Invalid parameter, locktime out of range"); rawTx.nLockTime = nLockTime; } @@ -368,18 +368,18 @@ CMutableTransaction ConstructTransaction(const UniValue& inputs_in, const UniVal uint32_t nSequence; if (rbfOptIn) { - nSequence = MAX_BIP125_RBF_SEQUENCE; + nSequence = MAX_BIP125_RBF_SEQUENCE; /* CTxIn::SEQUENCE_FINAL - 2 */ } else if (rawTx.nLockTime) { - nSequence = std::numeric_limits::max() - 1; + nSequence = CTxIn::SEQUENCE_FINAL - 1; } else { - nSequence = std::numeric_limits::max(); + nSequence = CTxIn::SEQUENCE_FINAL; } // set the sequence number if passed in the parameters object const UniValue& sequenceObj = find_value(o, "sequence"); if (sequenceObj.isNum()) { int64_t seqNr64 = sequenceObj.get_int64(); - if (seqNr64 < 0 || seqNr64 > std::numeric_limits::max()) { + if (seqNr64 < 0 || seqNr64 > CTxIn::SEQUENCE_FINAL) { throw JSONRPCError(RPC_INVALID_PARAMETER, "Invalid parameter, sequence number is out of range"); } else { nSequence = (uint32_t)seqNr64; -- cgit v1.2.3
