From 136f5664fec3a36456de8c7c05c747af3b90fd8a Mon Sep 17 00:00:00 2001 From: Sangbida Chaudhuri Date: Tue, 21 Apr 2026 07:38:06 +0930 Subject: [PATCH 01/17] wallet: add our_outputs + our_txs schema migrations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The next commits move wallet UTXO and tx tracking off chaintopology and onto bwatch. bwatch doesn't maintain a blocks table, but the legacy utxoset, transactions and channeltxs tables all have FOREIGN KEY references into blocks(height) (CASCADE / SET NULL), so we can't just retarget the existing tables. Instead, introduce parallel tables (our_outputs, our_txs) without the blocks(height) FK. The new bwatch-driven code writes only to these, the legacy tables stay populated by the existing code path during this release so downgrade still works, and a future release can drop them once we're past the downgrade window. Schema only here — wallet handlers that write into these tables and the backfill from outputs/transactions land in subsequent commits.

They arrive unwired so each handler commit stays small and the tree compiles at every step. The writers deliberately parallel got_utxo() / wallet_transaction_add() instead of replacing them: the legacy outputs/transactions tables must stay populated this release so downgrade works without a rescan.
