From 18f9d824154ead8a70ec86a6fe1fe0c6af649873 Mon Sep 17 00:00:00 2001 From: jedarden Date: Wed, 20 May 2026 07:46:12 -0400 Subject: [PATCH] P2.9: Expand reserved field write rejection tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement write-path rejection of reserved `_miroir_*` field names per plan §5 "Reserved fields": - `_miroir_shard`: Always rejected (unconditional) - `_miroir_updated_at`: Rejected when anti_entropy.enabled: true - `_miroir_expires_at`: Never rejected for writes (clients SET it) Changes: - Expand unit tests in documents.rs to cover all matrix cells - Add helper function for building reserved field errors - Add test for orchestrator shard injection flow - Add test for validation order (_miroir_shard before PK check) - Fix ttl_enabled parameter passing in search.rs and multi_search.rs All tests pass: 12 unit tests + 6 integration tests Co-Authored-By: Claude Opus 4.7 --- crates/miroir-proxy/src/routes/documents.rs | 160 +++++++++++++++--- .../miroir-proxy/src/routes/multi_search.rs | 2 + crates/miroir-proxy/src/routes/search.rs | 2 + 3 files changed, 142 insertions(+), 22 deletions(-) diff --git a/crates/miroir-proxy/src/routes/documents.rs b/crates/miroir-proxy/src/routes/documents.rs index 30b9715..abe9ec8 100644 --- a/crates/miroir-proxy/src/routes/documents.rs +++ b/crates/miroir-proxy/src/routes/documents.rs @@ -723,16 +723,36 @@ mod tests { } // Reserved field validation tests (P2.9) + // + // Tests the reserved field matrix per plan §5: + // - `_miroir_shard`: Always reserved (unconditional) + // - `_miroir_updated_at`: Reserved only when `anti_entropy.enabled: true` + // - `_miroir_expires_at`: Reserved only when `ttl.enabled: true` (read path only - writes always accept it) + + /// Helper to build the expected reserved field error. + fn reserved_field_error(field: &str) -> MeilisearchError { + MeilisearchError::new( + MiroirCode::ReservedField, + format!("document contains reserved field `{}`", field), + ) + } #[test] fn test_reserved_field_miroir_shard_always_rejected() { // _miroir_shard is ALWAYS reserved regardless of config - let doc_with_shard = serde_json::json!({"id": "test", "_miroir_shard": 5});
