From 365df2f3bea547b731c6f5e763f03439d33e3c00 Mon Sep 17 00:00:00 2001 From: Sangbida Chaudhuri Date: Sat, 11 Jul 2026 16:36:14 +0930 Subject: [PATCH 01/18] 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. Losing the FK also changes what NULL means. In the legacy tables a NULL blockheight was never written by hand: the ON DELETE SET NULL trigger produced it when a reorg deleted the block row. These tables have no such trigger, so unconfirmed is stored as blockheight 0 (NOT NULL) instead, for three reasons: - everything feeding these tables already speaks u32-with-0: watchman notifications carry blockheight as a required JSON number, and wallet_transaction_height() has always returned 0 for unconfirmed, so values bind straight through without a NULL/non-NULL branch at every read and write site; - integer comparisons keep working: the unconfirmed->confirmed promotion is a single "WHERE blockheight < ?" (0 sorts below any real height) and reorg rollback is "SET blockheight = 0 WHERE blockheight >= ?", where a NULL row would match neither; - it removes the footgun the legacy code warned about ("Note: blockheight=NULL is not the same as is NULL!"), where lookups had to branch between "= ?" and "IS NULL". The same logic gives txindex 0 = unconfirmed/unknown (a *confirmed* txindex of 0 means coinbase, which blockheight disambiguates) and reserved_til 0 = not reserved. NULL survives only where 0 is a real value or genuinely ambiguous: spendheight (NULL = unspent), channel_dbid, commitment_point. Schema only here — wallet handlers that write into these tables and the backfill from outputs/transactions land in subsequent commits.

They validate the matching output, notify invoice accounting, record confirmed deposits, and install watches for later spends. The watch_revert handler demotes the rows back to unconfirmed (the 0 sentinel) rather than deleting them: a row also carries state a rediscovery cannot restore (reserved_til, onchaind close metadata), and the still-armed watches re-promote it if the tx confirms again. This matches the legacy tables, whose blocks(height) foreign keys demote rows to NULL when the block row is removed. Unlike got_utxo(), this path does not write transaction_annotations: nothing reads per-transaction annotations anymore, so only the legacy scanner keeps populating them (for downgrade, like the other legacy tables). The watchman dispatch entry is wired in the following commit. Keep this path alongside got_utxo() and wallet_transaction_add(): the legacy scanner must continue populating outputs and transactions for one release so downgrades do not require a rescan.

This adds the receiving end of that watch: the dispatch entry plus the found/revert handlers. On watch_found (a tx consumed the outpoint): mark the output spent in our_outputs, store the spending tx in our_txs, and emit a withdrawal coin movement. On watch_revert (a reorg removed that tx): clear spendheight so the UTXO is spendable again.

Demote, never delete: a row also carries state the chain cannot re-deliver (reserved_til, onchaind close metadata), and this path runs not just on real reorgs but on every startup, when chaintopology invalidates its rescan window. Rediscovery re-promotes the row via wallet_add_our_output / wallet_transaction_add; a tx that never re-confirms just stays unconfirmed and unspendable.

Mirror every our_outputs write (insert, spend, unspend-on-spend-revert, reservation) into `outputs` so a downgrade for one release needs no copy-back or rescan. Reorg demotion needs no mirror: the legacy rows are demoted by their blocks(height) foreign keys when chaintopology removes the block. The mirroring stops in the release that removes chaintopology, freezing all the legacy tables at the same height. The spend mirror guards its spend_height the same way the insert guards confirmation_height: outputs.spend_height has a foreign key on blocks(height), which only chaintopology populates, and bwatch can deliver the spend before chaintopology has processed that block. Record NULL in that case (status already marks the row spent) and let chaintopology's own spend pass fill in the height. The wallet still reads from `outputs`; switching reads over to our_outputs comes next.

Since our_txs.blockheight is NOT NULL with 0 = unconfirmed, the legacy NULL handling disappears: wallet_transactions_by_height no longer needs its "IS NULL vs = ?" query split, and wallet_transaction_height reads the column unconditionally. wallet_transaction_add keeps dual-writing the legacy transactions table: the close path still inserts into channeltxs, whose transaction_id foreign key points at transactions(id), and wallet_get_funding_spend joins it. That legacy write can only go away with channeltxs itself.
