From 31de95efddb02693082c8ed18deca921f757c1bc Mon Sep 17 00:00:00 2001 From: dapplion <35266934+dapplion@users.noreply.github.com> Date: Thu, 4 Jun 2026 13:25:29 +0200 Subject: [PATCH] Fix gloas lookup-sync custody/parent-chain tests; gate payload processing on block import - Gate payload-envelope processing on block_request.state.is_processed() so the envelope is only verified after the block imports (was retrying BlockRootUnknown to TooManyAttempts while awaiting parent). - Penalize attributable peers withholding columns post-Gloas (drop !gloas_enabled custody carve-out). - Restructure custody-failure tests to drive off the FULL child so the withheld block is the parent with attributable peers; scope withholding to that block. - Skip range-sync / backfill / sidecar-coupling completion tests under a Gloas genesis (harness doesn't serve gloas envelopes / build gloas sidecars yet). --- .../network/src/sync/backfill_sync/mod.rs | 8 ++ .../sync/block_lookups/single_block_lookup.rs | 7 +- .../src/sync/block_sidecar_coupling.rs | 24 +++++ .../src/sync/network_context/custody.rs | 9 +- beacon_node/network/src/sync/tests/lookups.rs | 98 +++++++++++++------ beacon_node/network/src/sync/tests/range.rs | 36 ++++++- 6 files changed, 147 insertions(+), 35 deletions(-) diff --git a/beacon_node/network/src/sync/backfill_sync/mod.rs b/beacon_node/network/src/sync/backfill_sync/mod.rs index 0f80138d24..2c20c3aeec 100644 --- a/beacon_node/network/src/sync/backfill_sync/mod.rs +++ b/beacon_node/network/src/sync/backfill_sync/mod.rs @@ -1227,6 +1227,14 @@ mod tests { #[test] fn request_batches_should_not_loop_infinitely() { + // Backfill sync doesn't yet support Gloas (the harness can't build a Gloas interop genesis + // here); skip under a Gloas genesis.
