Any ETA on merging this obviously necessary fix? |
Bitcoin's consensus rules allows for indexes larger than u16, which would result in an overflow prior to this fix. This recently happened with a transaction on testnet: https://blockstream.info/testnet/tx/ca3b75556430e1adf9e9790bce9c73a3d9afdb42305588e64c65b258c06c05c9 Based on @junderw's mempool/electrs#75. Thanks! This change requires a full database reindex and bumps the DB_VERSION.
and not the main TxEdge structs, which were updated for the V3 schema.
