From a191d190bf8105025c2fc4ae3795f8e51d0710c6 Mon Sep 17 00:00:00 2001 From: azzerty23 Date: Fri, 1 May 2026 14:10:00 +0200 Subject: [PATCH 01/21] feat(policy): add optional error code to @@allow/@@deny attributes Adds an optional third `errorCode` string argument to @@allow, @@deny, @allow, and @deny policy attributes. When a create or post-update operation is rejected, the matching rule's code is surfaced on ORMError.policyCode so callers can handle specific policy violations without parsing error messages.

charset=UTF-8 Content-Transfer-Encoding: 8bit Rename and tighten the zero-rows diagnostic helper for update/delete: - Skip the diagnostic query entirely when no policies carry an error code, removing an unnecessary round-trip for the common case. - Fix BigInt comparison: use `> 0` negation instead of `=== 0` so numAffectedRows is handled correctly across drivers. - Reorder delete/update branches so the more specific guard (delete has no `using` restriction) runs first. - Inline the fetchPolicyCodes guard into a single early-exit path. Tests: add "does not throw for nonexistent row" cases for update and delete, and a focused test asserting the opt-in behaviour — rules without an errorCode keep the existing NotFound error, rules with an errorCode surface RejectedByPolicy instead.

charset=UTF-8 Content-Transfer-Encoding: 8bit Extend policy error code surfacing to `findFirst`/`findUnique` (and their `OrThrow` variants): when the query returns 0 rows, a diagnostic query now checks whether the row exists but was filtered by a deny/allow rule that carries an `errorCode`. If so, the handler throws `REJECTED_BY_POLICY` with the relevant codes instead of silently returning `null`. `findMany` is unaffected — it continues to use filter-based enforcement and returns an empty array for denied rows. This holds even for `findMany({ take: 1 })`, which generates LIMIT 1 SQL but remains a multi-row ORM operation by name.

charset=UTF-8 Content-Transfer-Encoding: 8bit On dialects lacking RETURNING support (e.g. MySQL), the ORM pre-loads entity ID fields before an UPDATE to identify the row for re-reading. This pre-load ran through onKyselyQuery plugin hooks, causing a read-policy denial to surface as "Record not found" before the UPDATE executed — masking the correct error code. Introduce internalQueryContextStorage (AsyncLocalStorage) to mark these internal pre-load queries; ZenStackQueryExecutor now skips all onKyselyQuery hooks when the flag is set.

This removes the node:async_hooks dependency from the policy plugin (and the orm package browser stub that worked around it), letting the Next.js sample drop serverExternalPackages overrides.
