From 9c89f1eee9cc50dcac68d5f846b05e6ed54fe904 Mon Sep 17 00:00:00 2001 From: 7layermagik <7layermagik@users.noreply.github.com> Date: Tue, 27 Jan 2026 13:23:46 -0600 Subject: [PATCH 01/12] feat: remove runtime manifest dependency for replay Replay now reads all seed data from state file instead of manifest at runtime. This eliminates the need for the manifest file after AccountsDB is built. Changes: - Add manifest_* fields to MithrilState schema (v2) - Create PopulateManifestSeed() to copy manifest data at build time - Update configureInitialBlock/FromResume to use state file - Update newReplayCtx to prefer state file over manifest - Update buildInitialEpochStakesCache to use ManifestEpochStakes - Clear ManifestEpochStakes after first replayed slot past snapshot - Backwards compat: fall back to manifest for old state files Co-Authored-By: Claude Opus 4.5 --- cmd/mithril/node/node.go | 16 ++- pkg/replay/block.go | 238 ++++++++++++++++++++++------------ pkg/replay/epoch.go | 29 ++++- pkg/snapshot/manifest_seed.go | 117 +++++++++++++++++ pkg/state/state.go | 64 ++++++++- 5 files changed, 374 insertions(+), 90 deletions(-) create mode 100644 pkg/snapshot/manifest_seed.go diff --git a/cmd/mithril/node/node.go b/cmd/mithril/node/node.go index edb7af08..b18603fe 100644 --- a/cmd/mithril/node/node.go +++ b/cmd/mithril/node/node.go @@ -809,6 +809,8 @@ func runVerifyRange(c *cobra.Command, args []string) { snapshotEpoch = sealevel.SysvarCache.EpochSchedule.Sysvar.GetEpoch(manifest.Bank.Slot) } mithrilState = state.NewReadyState(manifest.Bank.Slot, snapshotEpoch, "", "", 0, 0) + // Populate manifest seed data so replay doesn't need manifest at runtime + snapshot.PopulateManifestSeed(mithrilState, manifest) if err := mithrilState.Save(accountsDbDir);

Old state files will error with "delete AccountsDB and rebuild from snapshot".

<7layermagik@users.noreply.github.com> Date: Tue, 27 Jan 2026 20:53:41 -0600 Subject: [PATCH 07/12] fix: robust per-partition spool files for streaming rewards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses issues identified in ChatGPT review of ce71c54: 1. Per-partition spool files (O(N) → O(1) reads per partition) - Write to reward_spool__p.bin during calculation - Sequential read per partition during distribution (no indexing) - Eliminates O(N × partitions) file scanning 2. Channel-based single writer for error capture - All spool writes routed through one goroutine - Write errors captured in atomic.Value and propagated - Cleanup on failure 3. Silent account error tracking - Track failed account reads/unmarshals with atomic counters - Log warning with count and first error when failures occur 4. stakePointsCache elimination (already in ce71c54) - Two-pass streaming: Pass 1 for total points, Pass 2 recomputes + writes - Trades ~2x CPU for 0 extra RAM (~140MB saved) Co-Authored-By: Claude Opus 4.5 --- pkg/replay/rewards.go | 20 ++-- pkg/rewards/rewards.go | 168 +++++++++++++++++--------- pkg/rewards/spool.go | 265 ++++++++++++++++++++++++++++++++++------- 3 files changed, 346 insertions(+), 107 deletions(-) diff --git a/pkg/replay/rewards.go b/pkg/replay/rewards.go index e69abe62..dbfb0538 100644 --- a/pkg/replay/rewards.go +++ b/pkg/replay/rewards.go @@ -177,8 +177,9 @@ func beginPartitionedEpochRewardsDistribution(acctsDb *accountsdb.AccountsDb, sl panic(fmt.Sprintf("streaming rewards calculation failed: %s", err)) } -

strict errors, flat RAM, no nils - Clean PartitionedRewardDistributionInfo: remove unused Credits, RewardPartitions, StakingRewards, WorkerPool fields - Remove dead code: rewardDistributionTask, rewardDistributionWorker, InitWorkerPool, ReleaseWorkerPool, DistributeStakingRewardsForPartition - DistributeStakingRewardsFromSpool now streams with reader.Next() loop instead of ReadAll() for flat RAM during distribution - Use dynamic slices with append (no pre-allocated arrays with nils) - Implement strict error policy: any account read/unmarshal/marshal failure returns error immediately for consensus correctness - Add buffered I/O (1MB) to PartitionReader and partitionWriter - Remove all legacy single-file spool types from spool.go Net reduction: ~294 lines removed Co-Authored-By: Claude Opus 4.5 --- pkg/rewards/rewards.go | 239 ++++++++++++----------------------------- pkg/rewards/spool.go | 231 ++++----------------------------------- 2 files changed, 88 insertions(+), 382 deletions(-) diff --git a/pkg/rewards/rewards.go b/pkg/rewards/rewards.go index 481547d0..55baea59 100644 --- a/pkg/rewards/rewards.go +++ b/pkg/rewards/rewards.go @@ -2,6 +2,7 @@ package rewards import ( "fmt" + "io" "math" "path/filepath" "runtime" @@ -34,94 +35,10 @@ type PartitionedRewardDistributionInfo struct { TotalStakingRewards uint64 FirstStakingRewardSlot uint64 NumRewardPartitionsRemaining uint64 -
