Walkthrough

Introduces a new policy operation "post-update" and replaces the policy helper function future() with before(). Updates language tooling (stdlib, validation, linking, document building), runtime policy evaluation and executor/transaction flow, error hierarchy, SDK schema generation, and extensive tests/schemas. Also bumps package versions to 3.0.0-beta.8.

Poem

A whisk of code, a hop of fate,
We swapped the future for “before” of late.
Post-update rules now guide our trail,
With carrots of tests that never fail.
I nose the schema, tap-tap—approve!
Version bumped—let’s bunny-groove. 🥕🐇

PR Review for v3.0.0-beta.8 Release

Reviewing this PR that merges dev → main for the v3.0.0-beta.8 release with 831 additions and 373 deletions across 59 files.

Todo List

Set up development environment and dependencies
Review major architectural changes in runtime policy handling
Analyze new post-update policy implementation
Check language validation improvements
Review test coverage and new test files
Evaluate security implications of policy changes
Check for potential performance issues
Provide comprehensive feedback summary

🔍 Comprehensive Review Summary

✅ Strengths & Well-Implemented Features

1. Post-Update Policies - Major New Feature

Robust implementation: The new post-update policy operation is well-designed with proper validation flow
Complex SQL generation: Smart handling of before/after state comparison using VALUES clauses and JOINs
Comprehensive validation: Prevents relation field access from before() calls (security-conscious)
Transaction safety: All mutations properly wrapped in RepeatableRead transactions

2. Code Quality & Architecture

Strong type safety: Extensive use of TypeScript discriminated unions and type guards
Error handling: Proper error propagation with meaningful error messages
Test coverage: 191 lines of comprehensive test cases for the new feature
Backward compatibility: Changes are additive and don't break existing functionality

3. Language & Validation Improvements

Parser enhancements: Updated ZModel grammar to support post-update in policy rules
Runtime validation: Proper validation that before() calls are only allowed in post-update contexts
Developer experience: Good error messages and validation feedback

⚠️ Areas of Concern & Recommendations

1. Performance Considerations

Before-state loading: The system loads entire "before" entity state for post-update policies, which could be expensive for large entities
```
// packages/runtime/src/plugins/policy/policy-handler.ts:226-243
private async loadBeforeUpdateEntities(...) {
  // Loads all fields referenced in before() calls
}
```
Recommendation: Consider optimization for cases where only specific fields are needed

Complex SQL generation: Post-update validation generates nested queries with VALUES clauses

// Lines 138-160: Complex table construction for before-state comparison
const beforeUpdateTable: SelectQueryNode | undefined = beforeUpdateInfo ? { /*complex query*/ } : undefined;

Recommendation: Monitor query performance on large datasets

2. Security Assessment ✅

Access control: Proper prevention of relation field access from before() calls
SQL injection: Uses parameterized queries and proper SQL construction through Kysely
Transaction isolation: RepeatableRead isolation level prevents concurrent modification issues
No security vulnerabilities identified

3. Minor Issues

Expression Transformer Safety

The expression transformer properly handles field access validation:

// packages/language/src/validators/attribute-application-validator.ts:185-189
accept('error', `relation fields cannot be accessed from \`before()\``, { node: beforeCall });

Version Bumps

All package versions consistently bumped to 3.0.0-beta.8 - good release hygiene.

🚀 Technical Excellence

1. Policy Engine Robustness

Smart field collection: Only loads fields actually referenced in before() calls
Efficient ID handling: Ensures ID fields are always included for proper joining
Proper SQL casting: Handles type casting for different field types in VALUES clauses

2. Error Handling

Meaningful errors: Clear error messages for policy violations
Proper context: Errors include model context and operation type
Graceful failures: Transactions properly rolled back on policy failures

📊 Test Coverage Quality

The new test file (post-update.test.ts) covers:

✅ Basic post-update validation
✅ Simple allow/deny rules
✅ Relation field access
✅ before() function usage
✅ Query builder API compatibility
✅ Proper error validation

🏆 Overall Assessment

This is a high-quality release that introduces a significant new feature (post-update policies) with:

Solid architecture and implementation
Comprehensive testing
Good security practices
Proper error handling
Backward compatibility

The implementation demonstrates deep understanding of database transactions, SQL generation, and policy evaluation. The code follows established patterns and maintains high code quality standards.

🎯 Recommendation: APPROVE

This PR successfully implements post-update policies as a major feature enhancement with proper testing, security considerations, and maintainable code. The minor performance considerations noted above are acceptable for a beta release and can be optimized in future iterations based on real-world usage patterns.

The v3.0.0-beta.8 release appears ready for deployment.

⚠️ Outside diff range comments (2)

packages/language/res/stdlib.zmodel (1)

669-711: Document the new post-update operation in the attribute docs.

'post-update' is now part of the completion hints, but the parameter docs above @@allow/@@deny still say the list is just “create/read/update/delete/all”. Please update the text so the documentation matches the accepted operations and avoids confusing users.

packages/sdk/src/prisma/prisma-schema-generator.ts (1)

262-273: Add test coverage for @default(auth()) invocations
No existing test schemas include a @default(auth(...)) attribute. Add both simple and nested auth() cases in packages/runtime/test/schemas (and packages/language/test) to ensure isDefaultWithAuthInvocation reliably detects them.

🧹 Nitpick comments (2)

TODO.md (1)

104-105: Fix Markdown list indentation

These new sub-items use four leading spaces, but our markdownlint config (MD007) expects a two-space indent for nested bullets. Please drop the indent to two spaces so the checklist passes lint.

packages/runtime/test/policy/migrated/petstore-sample.test.ts (1)

5-5: Consider adding test cases for post-update constraint validation.

The test suite has been re-enabled to work with the new before()/post-update semantics. However, the current test only validates basic CRUD operations and doesn't verify the post-update constraints defined in the schema (e.g., preventing updates to name/category fields, or preventing orderId from being changed once set).

Consider adding test cases such as:

Attempting to update name or category on an existing pet (should fail post-update validation)

Attempting to change orderId after it's been set (should fail post-update validation)

Verifying that orderId CAN be set from null (should succeed)

Would you like me to generate these additional test cases?
