We create a deep copy of the channel state as we want to later expose
the data structure to the rpc, which already has helper methods to
marshal this representation to the rpc representation.
The ListChannelsWithPoliciesForCachePaginated query was missing the
policy version column, causing extractChannelPolicies to hardcode
lnwire.GossipVersion1 for that row type. Add cp1.version and
cp2.version to the query and use the fetched values instead.
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.
Introduce gossipV1 and gossipV2 package-level aliases in sql_store.go
to reduce verbosity in version switch statements. Leave hard-coded
v1/v2 call sites untouched so remaining upgrades are obvious.
In other words, it is now easy to see where our remaining work in the
sql_store.go file is by just searching for instances of
`lnwire.GossipVersion1`.
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.
Add a channelCacheKey struct keyed by {GossipVersion, chanID}, matching
the pattern already used by rejectCache. This prevents v1 and v2
channel data from colliding in the shared cache.
All callers in KVStore (always GossipVersion1) and SQLStore (version
from context) are updated to pass the version parameter.
This will be needed for later on when we update methods that use this
cache to be versioned (like ChannelUpdatesInHorizon).
Replace curl with wget for downloading release manifests and
signatures in verify-install.sh. wget handles redirects, retries, and
error reporting more robustly by default, which avoids silent download
failures that caused misleading "Invalid signature!" errors.
Also add error checking to all download calls so failures are reported
immediately with the URL that failed, and log which signature file and
user failed gpg verification.
When gpg --verify fails, include the signature filename, username,
and full GPG output in the error message. Previously only a generic
"Invalid signature!" was printed, making it hard to identify which
signer's signature was invalid.
Add a workflow that triggers when a release is published. It runs
verify-install.sh inside the official Docker image to validate
signatures and binary hashes. If verification fails, the release
is automatically set back to draft.
Switch the claude-dedupe-issues workflow from the default (most
expensive) model to claude-haiku-4-5, which is significantly cheaper
and sufficient for issue duplicate detection.
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 the UpsertChannelPolicy query to apply different staleness
checks based on gossip version. For v1 policies, continue checking
last_update timestamps. For v2 policies, check block_height instead,
using >= comparison to handle policies from the same block.
The version-specific WHERE clause ensures that policy updates are only
applied when they contain newer information according to the versioning
scheme appropriate for that gossip version.
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.
Make the reject cache version-aware so v1 and v2 policy state can be
cached independently per channel ID. Add helpers to store v1 timestamps
or v2 block heights and thread the versioned cache key through KV/SQL
store cache accesses.
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.
Add ChanEdgePolicyFromWire to construct ChannelEdgePolicy from channel
update messages, centralizing v1/v2 field mapping.
Update call sites to use the helper:
- discovery/gossiper: handleChanUpdate
- graph/builder: ApplyChannelUpdate
- routing/router_test: ApplyChannelUpdate test helper
This consolidates update-to-policy conversion logic across versions.
Replace MessageFlags and ChannelFlags bitfields in CachedEdgePolicy
with explicit boolean fields to improve clarity and support both v1
and v2 channel updates:
- Replace MessageFlags with HasMaxHTLC boolean.
- Replace ChannelFlags with IsNode1 and IsDisabled booleans.
- Update NewCachedPolicy to extract these fields version-appropriately:
- For v1: derive from MessageFlags and ChannelFlags bits.
- For v2: derive from policy.SecondPeer and policy.DisableFlags.
Update all call sites that used method calls IsNode1() and IsDisabled()
to instead access the fields directly. This includes:
- graph_cache.go: policy direction and disable checks
- unified_edges.go: HasMaxHTLC and IsDisabled checks
- Tests: policy construction and assertions
This refactoring improves readability by making the cached policy's
state explicit rather than encoded in bitfields, and enables seamless
support for both gossip protocol versions.
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.
Extend channel policy queries and structs to support v2-specific fields:
- Add BlockHeight field to track the block height for v2 policy updates.
- Add DisableFlags field for v2 channel disable messages.
Both fields are nullable (sql.NullInt64/Int16) to maintain backwards
compatibility with v1 channels. The fields are initialized as null in
updateChanEdgePolicy and threaded through all policy-related queries
(GetChannelBySCIDWithPolicies, ListChannelsByNodeID, UpsertEdgePolicy,
etc.) and the extractChannelPolicies helper.
This commit includes both the hand-written SQL query updates and the
corresponding sqlc-generated Go code.
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 channel edge fetching version-aware by adding gossip version
parameter to FetchChannelEdgesByID and FetchChannelEdgesByOutpoint.
Add corresponding methods to VersionedGraph. V2 policy building is
marked as TODO.
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.
