blockparser's Issues

failed to locate upstream transaction. advanced dev help needed.

I was start to adapt https://github.com/znort987/blockparser project to use with KMD (possible any ZCash Fork) blockchain. My expirience with internal blocks and transaction data structures is not big, but i'm already successfully modified original sources to walk through all blocks and sync it via it's hashes. Main problem was in different block header size in BTC and KMD blockchain. Also KMD block header have a variable size, during including equihash solution in block header. Now, main problems with block walking seems solved and i was able to succefull dump all addresses balances for a specially created assetchain DTT. But with main KMD blockchain here was a problem. For example, i can get all KMD balances at block 72233 executing ./parser_d allBalances -a 72233 -l 25 and first 25 TOP KMD addresses will be listed:

Perfect to create snapshot or for other purpose of use, isn't it? But if i try do same on a full blockchain (mean at max. current height) i will receive an error failed to locate upstream transaction. I was described this situation here - 7b6b520 . Seems we have something special with tx https://kmd.explorer.supernet.org/tx/f6fe725162c6dfed9651af5a115477c1607702dd4757d677c81d3cad6fc82358 . Or have more global problem with gTXOMap.

Unfortunatelly i don't clearly understand low-level tx structure, especially with regard to z-transaction and "Unparsed addresses". So, it's hard for me to determine what the problem we have here. Maybe somebody can help with this? Or will try to investigate why it can find upstream transaction in gTXOMap.

Thx in advance.
