这是初步的改动。看起来对吗？我还有更多要改的，这不全。稍后提交到 SVN。
Here's the preliminary change. Look right? I have more changes to make, this isn't all of it. Will SVN shortly.
bool CheckTransaction() const
{
// Basic checks that don't depend on any context
if (vin.empty() || vout.empty())
return error("CTransaction::CheckTransaction() : vin or vout empty");
// Check for negative and overflow values
int64 nTotal = 0;
foreach(const CTxOut& txout, vout)
{
if (txout.nValue < 0)
return error("CTransaction::CheckTransaction() : txout.nValue negative");
if (txout.nValue > 21000000 * COIN)
return error("CTransaction::CheckTransaction() : txout.nValue too high");
nTotal += txout.nValue;
if (nTotal > 21000000 * COIN)
return error("CTransaction::CheckTransaction() : txout total too high");
}
if (IsCoinBase())
{
if (vin[0].scriptSig.size() < 2 || vin[0].scriptSig.size() > 100)
return error("CTransaction::CheckTransaction() : coinbase script size");
}
else

if (txin.prevout.IsNull())
return error("CTransaction::CheckTransaction() : prevout is null");
}
return true;
