From fcc3d59cbc823d64d6969171ff616425e3acb47d Mon Sep 17 00:00:00 2001 From: Calin Martinconi Date: Mon, 20 Jul 2026 22:46:44 +0300 Subject: [PATCH 01/14] feat(storer): converge divergent SOCs in the storage layer (SWIP-101) Two valid single owner chunks can share an address, batch and stamp while wrapping different content. The stamp signs the chunk address, so both carry an identical stamp and produce an identical stamp hash. The content-blind existence check at the top of reserve.Put therefore treated the second chunk as already stored and dropped it, leaving each node holding whichever chunk reached it first. Neighborhoods never converged, and the reserve sampler computed different commitments from the same address. Make the check content-aware via the pullsync sum, and settle the divergence here rather than in the protocol: the chunk wrapping the lower CAC address wins. The rule depends only on the two payloads, so every node reaches the same answer regardless of arrival order. On a win the chunk is replaced in place, reusing the stamp index and stamp entries, which are identical for both. The bin ID is bumped so peers that already synced past the old one are offered the replacement. The reserve size is unchanged: one chunk goes in, one comes out. Pullsync treats a lost tie-break as an expected outcome rather than a sync error, since the node already holds the chunk the neighborhood converges on. Divergent chunks under different batches are not covered: they occupy different stamp indices, so no tie-break fires. --- pkg/pullsync/metrics.go | 7 + pkg/pullsync/pullsync.go | 8 + pkg/storage/storage.go | 40 +++++ pkg/storage/storage_test.go | 86 ++++++++++ pkg/storer/internal/reserve/reserve.go | 130 +++++++++++++-- pkg/storer/internal/reserve/reserve_test.go | 165 ++++++++++++++++++++ 6 files changed, 427 insertions(+), 9 deletions(-) diff --git a/pkg/pullsync/metrics.go b/pkg/pullsync/metrics.go index 57e26916c93..d20453d65ff 100644 --- a/pkg/pullsync/metrics.go +++ b/pkg/pullsync/metrics.go @@ -15,6 +15,7 @@ type metrics struct { MissingChunks prometheus.Counter // number of reserve get errs ReceivedZeroAddress prometheus.Counter // number of delivered chunks with invalid address ReceivedInvalidChunk prometheus.Counter // number of delivered chunks with invalid address + DivergentRejected prometheus.Counter // number of delivered chunks that lost the divergence tie-break Delivered prometheus.Counter // number of chunk deliveries SentOffered prometheus.Counter // number of chunks offered SentWanted prometheus.Counter // number of chunks wanted @@ -57,6 +58,12 @@ func newMetrics() metrics { Name: "received_invalid_chunks", Help: "Total invalid chunks delivered.", }), + DivergentRejected: prometheus.NewCounter(prometheus.CounterOpts{ + Namespace: m.Namespace, + Subsystem: subsystem, + Name: "divergent_rejected", + Help: "Total delivered chunks discarded for losing the divergence tie-break.", + }), Delivered: prometheus.NewCounter(prometheus.CounterOpts{ Namespace: m.Namespace, Subsystem: subsystem, diff --git a/pkg/pullsync/pullsync.go b/pkg/pullsync/pullsync.go index 92886bfd896..8c15f295d21 100644 --- a/pkg/pullsync/pullsync.go +++ b/pkg/pullsync/pullsync.go @@ -391,6 +391,14 @@ func (s *Syncer) Sync(ctx context.Context, peer swarm.Address, bin uint8, start chunkErr = errors.Join(chunkErr, err) continue } + // the chunk diverged from the one already stored and lost the + // tie-break.

The stamp signs the chunk address, so both carry an identical stamp and produce an identical stamp hash. The content-blind existence check at the top of reserve.Put therefore treated the second chunk as already stored and dropped it, leaving each node holding whichever chunk reached it first. Neighborhoods never converged, and the reserve sampler computed different commitments from the same address. Make the check content-aware via the pullsync sum, and settle the divergence here rather than in the protocol: the chunk wrapping the lower CAC address wins. The rule depends only on the two payloads, so every node reaches the same answer regardless of arrival order. On a win the chunk is replaced in place, reusing the stamp index and stamp entries, which are identical for both. The bin ID is bumped so peers that already synced past the old one are offered the replacement. The reserve size is unchanged: one chunk goes in, one comes out. Pullsync treats a lost tie-break as an expected outcome rather than a sync error, since the node already holds the chunk the neighborhood converges on. Divergent chunks under different batches are not covered: they occupy different stamp indices, so no tie-break fires. --- pkg/pullsync/metrics.go | 7 + pkg/pullsync/pullsync.go | 8 + pkg/storage/storage.go | 40 +++++ pkg/storage/storage_test.go | 86 ++++++++++ pkg/storer/internal/reserve/reserve.go | 136 ++++++++++++++-- pkg/storer/internal/reserve/reserve_test.go | 165 ++++++++++++++++++++ 6 files changed, 433 insertions(+), 9 deletions(-) diff --git a/pkg/pullsync/metrics.go b/pkg/pullsync/metrics.go index 57e26916c93..d20453d65ff 100644 --- a/pkg/pullsync/metrics.go +++ b/pkg/pullsync/metrics.go @@ -15,6 +15,7 @@ type metrics struct { MissingChunks prometheus.Counter // number of reserve get errs ReceivedZeroAddress prometheus.Counter // number of delivered chunks with invalid address ReceivedInvalidChunk prometheus.Counter // number of delivered chunks with invalid address + DivergentRejected prometheus.Counter // number of delivered chunks that lost the divergence tie-break Delivered prometheus.Counter // number of chunk deliveries SentOffered prometheus.Counter // number of chunks offered SentWanted prometheus.Counter // number of chunks wanted @@ -57,6 +58,12 @@ func newMetrics() metrics { Name: "received_invalid_chunks", Help: "Total invalid chunks delivered.", }), + DivergentRejected: prometheus.NewCounter(prometheus.CounterOpts{ + Namespace: m.Namespace, + Subsystem: subsystem, + Name: "divergent_rejected", + Help: "Total delivered chunks discarded for losing the divergence tie-break.", + }), Delivered: prometheus.NewCounter(prometheus.CounterOpts{ Namespace: m.Namespace, Subsystem: subsystem, diff --git a/pkg/pullsync/pullsync.go b/pkg/pullsync/pullsync.go index 53ac6d7628a..32a6dba4705 100644 --- a/pkg/pullsync/pullsync.go +++ b/pkg/pullsync/pullsync.go @@ -394,6 +394,14 @@ func (s *Syncer) Sync(ctx context.Context, peer swarm.Address, bin uint8, start chunkErr = errors.Join(chunkErr, err) continue } + // the chunk diverged from the one already stored and lost the + // tie-break.

an order-dependent outcome means neighborhoods that can never agree. The harness drives conflict sets through every permutation against a fresh reserve and compares canonical state fingerprints (bin IDs excluded: they are order-dependent by design), asserting the sum index invariants on every run as a side effect. Converging on this branch: the equal-timestamp CAC tie-break, the identical-stamp divergent SOC resolution and timestamp ordering. Five constellations are order-dependent, all falling through the same gap: at equal stamp timestamps the tie-break fires only for a content addressed incoming chunk with a different address, and every other case drops into an unconditional replace. These are marked unresolved in the case table: they log the divergence without failing the suite, and setting RESERVE_STRICT_CONVERGENCE=1 turns them into failures, which gives the reserve.Put refactor a concrete target. A case marked unresolved that starts converging fails loudly so the marker is removed and the table stays honest. Testing methodology and findings are documented alongside the refactor notes for reuse. --- .../internal/reserve/convergence_test.go | 363 ++++++++++++++++++ 1 file changed, 363 insertions(+) create mode 100644 pkg/storer/internal/reserve/convergence_test.go diff --git a/pkg/storer/internal/reserve/convergence_test.go b/pkg/storer/internal/reserve/convergence_test.go new file mode 100644 index 00000000000..94cfe0cdfc7 --- /dev/null +++ b/pkg/storer/internal/reserve/convergence_test.go @@ -0,0 +1,363 @@ +// Copyright 2026 The Swarm Authors.
