From 819717569ddd91d9600ef64677cd5e09212b7df7 Mon Sep 17 00:00:00 2001 From: PastaClaw Date: Sat, 28 Feb 2026 13:57:19 -0600 Subject: [PATCH 1/5] fix(drive): consolidate historical contract proof verification retry logic When contract_known_keeps_history is None, any result other than Ok((hash, Some(contract))) now triggers exactly one retry with history enabled. Previously, retry logic was scattered across multiple match arms and several failure paths bypassed it entirely. Refactored verify_contract_v0 and verify_contract_return_serialization_v0 to extract _given_history helpers containing the pure verification logic, with retry decisions made solely in the outer functions.

charset=UTF-8 Content-Transfer-Encoding: 8bit The previous commit incorrectly restricted retry to Err(_) only, but Ok(None) from the non-historical path is a legitimate trigger for historical retry — it means the contract exists in the historical path, not that it's absent. Restoring the _ catch-all preserves the original fix from a7fec8bf3. Test assertions now require contracts to be returned (not accept None) for cases where the contract definitely exists, eliminating tautological acceptance paths. --- .../src/verify/contract/verify_contract/v0/mod.rs | 5 +---- .../verify_contract_return_serialization/v0/mod.rs | 5 +---- packages/rs-drive/tests/query_tests.rs | 13 +++++++------ 3 files changed, 9 insertions(+), 14 deletions(-) diff --git a/packages/rs-drive/src/verify/contract/verify_contract/v0/mod.rs b/packages/rs-drive/src/verify/contract/verify_contract/v0/mod.rs index bf07f80dfd7..69db47c079f 100644 --- a/packages/rs-drive/src/verify/contract/verify_contract/v0/mod.rs +++ b/packages/rs-drive/src/verify/contract/verify_contract/v0/mod.rs @@ -56,10 +56,7 @@ impl Drive { if contract_known_keeps_history.is_none() { match &result { Ok((_, Some(_))) => result, - // Ok(None) is a valid absence proof — contract genuinely doesn't exist. - // Don't retry; the server builds a non-historical query for missing contracts. - Ok((_, None)) => result, - Err(_) => { + _ => { tracing::debug!( ?contract_id, "retrying contract verification with history enabled" diff --git a/packages/rs-drive/src/verify/contract/verify_contract_return_serialization/v0/mod.rs b/packages/rs-drive/src/verify/contract/verify_contract_return_serialization/v0/mod.rs index 02e4033ea6a..1eb7beb1ba9 100644 --- a/packages/rs-drive/src/verify/contract/verify_contract_return_serialization/v0/mod.rs +++ b/packages/rs-drive/src/verify/contract/verify_contract_return_serialization/v0/mod.rs @@ -58,10 +58,7 @@ impl Drive { if contract_known_keeps_history.is_none() { match &result { Ok((_, Some(_))) => result, - // Ok(None) is a valid absence proof — contract genuinely doesn't exist. - // Don't retry; the server builds a non-historical query for missing contracts. - Ok((_, None)) => result, - Err(_) => { + _ => { tracing::debug!( ?contract_id, "retrying contract verification with history enabled" diff --git a/packages/rs-drive/tests/query_tests.rs b/packages/rs-drive/tests/query_tests.rs index 0f11ebf9e4d..333a2a8d4d9 100644 --- a/packages/rs-drive/tests/query_tests.rs +++ b/packages/rs-drive/tests/query_tests.rs @@ -4744,9 +4744,10 @@ mod tests { ) .expect("verification with None should succeed"); assert_eq!(root_hash, proof_root_hash); - if let Some(contract) = proof_contract { - assert_eq!(latest_contract, contract); - } + assert_eq!( + latest_contract, + proof_contract.expect("contract exists and was updated — None retry must return it") + ); // Test 2: Some(true) - direct historical, must succeed since proof was generated // for a historical contract @@ -4806,9 +4807,9 @@ mod tests { ) .expect("return_serialization with None should succeed for historical contract"); assert_eq!(root_hash, proof_root_hash_4); - if let Some((deserialized, _bytes)) = proof_contract_4 { - assert_eq!(latest_contract, deserialized); - } + let (deserialized, _bytes) = + proof_contract_4.expect("contract exists — return_serialization must return it"); + assert_eq!(latest_contract, deserialized); } #[cfg(feature = "server")]
