I do recall reading somewhere that there is perhaps a bug that prevents this particular tx (i.e. in block 0) from being seen via "getrawtransaction" - perhaps Pieter would know more about this.
At the same time I would be curious to know if "-blocknotify=cmd" would work (is that how blockexplorer got its information?).
In any case that 50 BTC *cannot* be spent (so no need to worry about this tx as being an UTXO).
can't find raw tx:
1.
pblocktree->ReadTxIndex(hash, postx) read failure, tx is NOT in pblocktree.
2.
view.GetCoins(hash, coins) get failure too, this tx's coin is not in CCoinsViewCache.
because this tx is in block 0, so I modify source code as below:
--- a/src/main.cpp
+++ b/src/main.cpp
@@ -1002,7 +1002,7 @@ bool GetTransaction(const uint256 &hash, CTransaction &txOut, uint256 &hashBlock
if (view.GetCoins(hash, coins))
nHeight = coins.nHeight;
}
- if (nHeight > 0)
+ if (nHeight >= 0)
pindexSlow = FindBlockByHeight(nHeight);
}
}
rebuild it and run, still not work.
Write tx index code is in function
CBlock::ConnectBlock:
bool CBlock::ConnectBlock(CValidationState &state, CBlockIndex* pindex, CCoinsViewCache &view, bool fJustCheck) {
...
if (fTxIndex)
if (!pblocktree->WriteTxIndex(vPos))
return state.Abort(_("Failed to write transaction index"));
...
}
maybe forget to ConnectBlock 'GenesisBlock', so I try
bitcoind -loadblock="~/Library/Application\ Support/Bitcoin/blocks/blk00000.dat", and it works:
