We now return an error when blinded and non blinded attempts are
combined. This was theoretically possible to register a legacy
attempt in combination with a blinded payment. This would have
been prevented by other checks in the code because legacy payments
are not split into shards.
Since the gossip protocols are completely disjoint, we need to treat
messages on the two protocols completely separately and should not let
rejections on one protocol affect how we treat messages on the other.
Define a GossipVersion enum along with a GossipMessage interface to be
satisfied by all gossip related messages. This will be useful later on
when we want to make decisions based on the protocol version that a
message is part of.
The config file format changed. The tool golangci-lint migrate
was used to migrate the old config. However old comments and also
the structure of the disabled linters was preserved.
Moreover the new v2 version introduced new linters, we disable
3 of them because they are very noise and we do not really want
to check for them: funcorder, noinlineerr, embeddedstructfieldcheck.
Add comprehensive test coverage to verify that state handler errors cause
the channelGraphSyncer goroutine to exit cleanly without entering endless
retry loops. These tests use mutation testing principles to ensure they
would fail if the fixes were removed.
TestGossipSyncerStateHandlerErrors is a table-driven test covering four
scenarios: context cancellation and peer disconnect during syncingChans
state, and context cancellation and network errors during queryNewChannels
state. Each test case verifies both attempt count (no endless loop) and
clean shutdown (no deadlock).
TestGossipSyncerProcessChanRangeReplyError verifies that errors from
processChanRangeReply in the waitingQueryRangeReply state cause clean
exit. This test sends multiple malformed messages and checks that only
the first is processed before the goroutine exits, using channel queue
depth to detect if the goroutine is still running.
All tests are race-detector clean and use mutation testing validation:
removing any of the error return statements causes the corresponding
tests to fail, confirming the tests properly verify the fixes.
This commit fixes a critical bug where the channelGraphSyncer goroutine
would enter an endless loop when context cancellation or peer disconnect
errors occurred during the syncingChans or queryNewChannels states.
The root cause was that state handler functions (handleSyncingChans and
synchronizeChanIDs) did not return errors to the main goroutine loop.
When these functions encountered fatal errors like context cancellation,
they would log the error and return early without changing the syncer's
state. This caused the main loop to immediately re-enter the same state
handler, encounter the same error, and loop indefinitely while spamming
error logs.
The fix makes error handling explicit by having state handlers return
errors. The main channelGraphSyncer loop now checks these errors and
exits cleanly when fatal errors occur. We return any error (not just
context cancellation) because fatal errors can manifest in multiple
forms: context.Canceled, ErrGossipSyncerExiting from the rate limiter,
lnpeer.ErrPeerExiting from Brontide, or network errors like connection
closed. This approach matches the error handling pattern already used in
other goroutines like replyHandler.
This commit addresses a regression where Neutrino rescanning starts
from an outdated height (~100k blocks behind) instead of using the
current synced height.
Root Cause:
In commit 16a8b623b, the initialization order was changed so that
Chain Notifier starts before wallet syncing completes. This means
the rescan begins using the stale height from BuildChainControl
rather than the fully synced height.
Old behavior (commit 1dfb5a0c2):
1. RPC server starts
2. Headers sync as part of daemon server
3. Chain Notifier starts after sync completes
4. Rescan begins from current (synced) height
Current behavior (regression):
1. Chain Notifier starts in newServer (before RPC)
2. Wallet sync happens after RPC server starts
3. Rescan uses outdated height from BuildChainControl
Solution:
- Ensure headers are fully synced before starting the chain notifier,
and after starting the RPC server.
- Move chain notifier startup to its correct location after headers are
fully synced.
- Make sure the starting beat is lazily called after chain notifier
started and before that starting beat result is used.
