wallet: Cache the max_index for bip32 and bip86 address indices

This commit is a straightforward performance optimization. It caches two address-index values in memory instead of reading them from the database twice for every transaction output in every scanned block. The change fixes a slowdown during…

wallet: Update the max_index cache when issuing new addresses

This commit fixes a bug where Core Lightning's in-memory record of the highest address index could fall out of step with the database. When a user generated a new on-chain address, the code updated the database directly but left the cached…

wallet: Read the max_index for addresses from the in-memory cache

This small change makes the wallet's address-listing command read a cached value from memory instead of querying the database each time. It appears to be a performance or consistency cleanup rather than a security fix. There is no direct e…

renepay: skip channels disabled in gossmap

This fix corrects a routing bug in Core Lightning's 'renepay' payment plugin. Previously, renepay could try to send payments through Lightning channels that the wider network had already marked as disabled, causing payment attempts to fail…

test: Add a test for the UDS opentelemetry trace sink

This commit adds a new automated test that checks whether Core Lightning can send tracing data over a Unix domain socket. It is purely a test file change and does not modify any production code, configuration defaults, or network behavior.…

trace: add UDS datagram socket backend, decouple from USDT

This commit adds a new diagnostic feature: it lets Core Lightning send internal tracing data (timing and span information) over a local Unix Domain Socket, and it makes the tracing code always compile even when USDT probes are not availabl…

chore: Ensure the logging library does not get upset when output capture is disabled.

This commit only changes how the project's automated testing and build scripts set an environment variable (TEST_LOG_IGNORE_ERRORS=1). It tells the test logging library not to treat certain log-related issues as fatal during test runs. The…
