Convert compareEdgePolicies into a test helper that accepts a
testing handle and performs assertions directly.
Update call sites to invoke the helper instead of threading errors
into immediate require.NoError checks.
Replace remaining fatal-style assertions in graph/db tests with direct
testify/require helpers. This simplifies control flow and reduces
indentation by using NoError, True/False, Equal, Len, Empty, and Nil
assertions directly.
Add a gossip version parameter to FetchChanInfos in the Store interface
and both KV/SQL implementations. Update the graph builder caller and
refactor related tests.
Add a gossip version parameter to HighestChanID in the Store interface
and both KV/SQL implementations. Update callers in the discovery
ChanSeries and server bootstrap code.
Add a gossip version parameter to DisabledChannelIDs in the Store
interface and both implementations. Add a new version-filtered SQL
query and update the builder caller.
Convert testEdgeInfoUpdates and testBatchedUpdateEdgePolicy to run
against both v1 and v2 gossip versions, exercising the versioned
Store methods added in prior commits.
Add a gossip version parameter to the ChannelID method (outpoint to
short channel ID lookup) in the Store interface and both KV/SQL
implementations. Update the VersionedGraph wrapper and tests.
Refactor the createChannelEdge test helper to be version-aware,
supporting both v1 and v2 channel and policy creation. This prepares
the test infrastructure for subsequent commits that version individual
Store methods.
Add a gossip version parameter to ForEachNodeDirectedChannel on the
Store interface and both DB implementations (KVStore, SQLStore). The
NodeTraverser and routing.Graph interfaces remain unversioned since
pathfinding operates on the merged cross-version cache view.
The cache population in populateCache is updated in the same commit
because it is logically atomic with the versioning changes: the graph
cache is the unversioned, merged view used by pathfinding, so it must
be populated with data from all gossip versions. Without this change,
only v1 data would be loaded into the cache, making v2 nodes and
channels invisible to pathfinding.
Add gossip version parameters to ForEachNodeCacheable and
ForEachChannelCacheable in the Store interface and both implementations.
Thread the version through SQL helpers and update call sites/tests
accordingly.
Make fillTestGraph version-aware and update its call sites to pass an
explicit gossip version (currently v1 at these call sites).
This is a test-helper refactor only; cacheable-iteration API versioning
is handled in the next commit.
Add a gossip version parameter to ForEachSourceNodeChannel in the Store
interface and both KV/SQL implementations. The VersionedGraph wrapper
delegates with its baked-in version. Convert the
testAddChannelEdgeShellNodes and testForEachSourceNodeChannel tests to
run against both v1 and v2 gossip versions.
Update ForEachNodeChannel to accept a gossip version parameter,
allowing callers to specify which gossip version's channels should be
iterated. This change mirrors the approach taken in ForEachChannel and
prepares the graph database for supporting multiple gossip versions
while maintaining backward compatibility.
The Store interface is updated to include the version parameter, and
both KVStore and SQLStore implementations are updated accordingly:
- KVStore validates that only GossipVersion1 is requested, returning
ErrVersionNotSupportedForKVDB for other versions.
- SQLStore passes the version through to the underlying node query,
enabling version-specific channel iteration.
The ChannelGraph wrapper is updated to accept and pass through the
version parameter. VersionedGraph gains a ForEachNodeChannel method
that automatically uses its configured gossip version, providing a
clean interface for version-specific operations.
Update all call sites to explicitly pass lnwire.GossipVersion1, except
for the local channel manager in server.go which now uses the v1Graph
directly (matching the pattern used in other parts of the codebase).
Convert testEdgePolicyCRUD to a versioned test that runs against both
v1 and v2 gossip versions. Update the test to use version-specific
edge creation helpers and to test version-specific fields and flag
behavior (ChannelFlags/MessageFlags for v1, DisableFlags/
ExtraSignedFields for v2).
Update ForEachChannel to accept a gossip version parameter, allowing
callers to specify which gossip version's channels should be iterated.
This change prepares the graph database for supporting multiple gossip
versions while maintaining backward compatibility.
The KVStore implementation validates that only GossipVersion1 is
requested, returning ErrVersionNotSupportedForKVDB for other versions.
The SQLStore implementation validates known versions and passes the
version through to the underlying paginated query.
Update VersionedGraph to include a ForEachChannel method that
automatically uses its configured gossip version, and update the
DescribeGraph RPC handler to use the v1Graph instead of the global
graphDB.
Add a new HasChannelEdge method that takes a gossip version parameter
and returns only existence and zombie status, without timestamp data.
This supports both v1 and v2 gossip protocols.
The original HasChannelEdge method is renamed to HasV1ChannelEdge to
preserve v1-specific functionality for callers that need timestamp
information. All call sites are updated accordingly.
The SQL store implementation now handles both gossip versions, using
timestamps for v1 and block heights for v2 policies, with proper
reject cache support for both versions.
Update buildChanPolicy and related functions in both KV and SQL stores
to properly construct ChannelEdgePolicy with version-specific fields:
KVStore changes:
- Reject non-v1 policies in updateEdgePolicy and serializeChanEdgePolicy
since KV store only supports v1 gossip protocol.
- Set Version to GossipVersion1 when deserializing policies from KV.
SQLStore changes:
- Add isNode1 parameter to buildChanPolicy functions to properly set
SecondPeer field (v2 uses SecondPeer instead of ChannelFlags direction).
- Extract Version from database and populate version-specific fields:
- For v1: MessageFlags, ChannelFlags, LastUpdate, ExtraOpaqueData
- For v2: DisableFlags, LastBlockHeight, ExtraSignedFields
- Thread isNode1 through buildChanPolicyWithBatchData and
buildCachedChanPolicies call sites.
This enables the SQL store to read and reconstruct both v1 and v2
channel policies from the database with proper field mapping.
Extend ChannelEdgePolicy to support v2 channel updates by adding:
- Version field to track gossip protocol version (v1 or v2).
- LastBlockHeight for v2's block-height-based timestamps.
- SecondPeer flag to indicate which peer announced the policy in v2.
- DisableFlags for v2-specific channel disable signaling.
- ExtraSignedFields map for v2 extra signed TLV data.
Add version-aware methods:
- IsNode1() determines if the policy was announced by node_1, handling
both v1 (via ChannelFlags direction bit) and v2 (via SecondPeer).
- IsDisabled() checks disable status using ChannelFlags for v1 and
DisableFlags for v2.
- String() provides version-appropriate string representations.
The new fields use zero values for v1 compatibility (Version defaults
to GossipVersion1, LastBlockHeight to 0, SecondPeer to false). This
lays the groundwork for v2 policy support; a subsequent commit will
handle reading and writing these fields from/to the database.
This commit improves handling of missing channel signatures in the
database:
- Return nil from auth proof accessors instead of empty slices so that
missing signatures are stored as NULL in SQL.
- Update public channel checks to require signature length > 0, which
properly handles existing empty bytea values in the database.
- Add regression test covering empty v1 and v2 channel signatures to
prevent future issues.
Make IsZombieEdge version-aware and add corresponding method to
VersionedGraph. Convert TestEdgeInsertionDeletion to versioned test
using the createEdge helper for both v1 and v2 channel testing.
Make IsPublicNode version-aware by routing to the appropriate SQL
query based on gossip version. V1 and v2 have different criteria for
determining node publicity (v1 requires four signatures, v2 requires
one). Convert TestNodeIsPublic to versioned test for both protocols.
Add version-aware DeleteChannelEdges method to VersionedGraph and
update call sites in graph builder, rpcserver, and server to use
versioned graphs. This ensures channel deletion operations are
properly scoped to the correct gossip version.
Convert TestPartialNode to a versioned test that runs for both v1 and
v2 gossip versions, ensuring shell node creation works correctly for
both channel types.
