Revert "tests: drop obsolete x-prefix in compacter-slow.sh"

This commit re-adds an old-style 'x' prefix to a string comparison in a test helper script. It is a test-only change with no effect on the actual Core Lightning node software, user funds, network behavior, or security. The change simply re…

Revert "doc: require Homebrew GNU make and gpatch on macOS"

This commit is a simple documentation revert. It undoes a previous change that told macOS users to install GNU make and GNU patch from Homebrew and to put those tools first in their command path. The reverted instructions now omit gpatch a…

doc: require Homebrew GNU make and gpatch on macOS

This commit only updates macOS installation instructions in the documentation. It tells macOS users to install newer GNU versions of 'make' and 'patch' from Homebrew because Apple's built-in tools are too old for building and running sourc…

tests: drop obsolete x-prefix in compacter-slow.sh

This commit is a trivial shell script cleanup. It removes an old-fashioned 'x' prefix from a string comparison in a test helper script so that a newer version of the Shellcheck linter stops warning about it. The change does not alter progr…

wallet: handle reorgs for our_outputs/our_txs by hand

This commit fixes how Core Lightning's wallet records handle blockchain reorganizations (reorgs) for two newer database tables, our_outputs and our_txs. Previously, these tables were not properly updated when blocks were removed or rolled …

lightningd: only run watchman under --experimental-bwatch

This commit gates a new experimental chain-watching subsystem called 'bwatch' behind an explicit --experimental-bwatch flag. Previously, the watchman helper was always created, which could have caused both the old chain watcher and the new…

Race condition between legacy chain watcher and new bwatch watcher prevented by gating watchman creation behind an opt-in flagwatchman_* entry points made NULL-safe so disabled code paths are explicit no-opsJSON RPC command now returns a controlled error instead of dereferencing a NULL watchman

wallet: route transaction reads/writes through our_txs

This commit changes how Core Lightning stores and reads wallet-related transactions. It moves most reads to a new table called our_txs while still keeping the old transactions table updated for compatibility. The main concern is that the c…

wallet: dual-write chaintopology UTXO changes into our_outputs

This is a database refactoring commit in Core Lightning. It makes the wallet write UTXO (unspent transaction output) state to a new table called our_outputs in addition to the legacy outputs table, while reads still use the old table. The …

wallet: handle bwatch wallet/utxo spend notifications

This commit adds the missing bookkeeping that runs when Core Lightning's own on-chain wallet spends a UTXO. It makes the node mark the UTXO as spent, record the spending transaction, and log a withdrawal coin movement. It also handles bloc…

This change makes Core Lightning register long-lasting 'watches' for all wallet deposit addresses when the node starts up, so the new bwatch plugin can spot incoming payments from the first block it scans. It also removes a now-redundant p…

wallet: add migrate_backfill_bwatch_tables

This commit adds a database migration that copies existing wallet data into new tables used by an upcoming 'bwatch' wallet component. It is a data backfill, not a code fix for an active vulnerability. The main risk is that if the migration…

wallet: add our_outputs + our_txs schema migrations

This commit only adds two new empty database tables (our_outputs and our_txs) to Core Lightning's wallet. It is a preparatory schema change for a future feature; no code reads from or writes to these tables yet, and no existing behavior is…

tests: query our_outputs in test_connection.py

This commit only updates test code to query a renamed database table (`our_outputs` instead of `outputs`) and adjusts column names/conditions. It does not change production wallet logic or fix a security bug. There is no security relevance.

This commit only updates internal test code to query a new database table (our_outputs) instead of an old one (outputs). It does not change the actual wallet or node software that users run, so it cannot directly affect security.
