Summary

The ROADMAP (Phase 1.4) specifies an in-memory cache with 30-second TTL using sync.RWMutex and cache invalidation on write operations. The cache logic in internal/gitea/client.go has no dedicated tests — a TTL regression or invalidation bug would cause stale data to be served after label assignments or review submissions.

What to Do

  1. Add tests in internal/gitea/client_test.go for:
    • Cache hit: call a read function twice with the same key, verify only one HTTP call is made to the mock server
    • Cache miss after TTL: manipulate the cache entry timestamp to simulate expiry, verify the next read triggers a fresh HTTP call
    • Cache invalidation: call InvalidateAll() or a write operation (e.g., ApplyLabel()), verify the next read fetches fresh data
  2. Use a mock HTTP server to count real API calls

Acceptance Criteria

  • go test ./internal/gitea/... passes with the new tests
  • TTL expiry is tested (can use a very short TTL or manipulate the internal timestamp)
  • Write operations correctly invalidate cache entries
  • No real Gitea API calls in tests

Roadmap Reference

Phase 1.4 — Gitea Aggregation Layer: in-memory cache with 30s TTL


Closing: TestCache, TestCacheExpiry, and TestInvalidateAll in internal/gitea/client_test.go already cover all acceptance criteria: cache hit/miss, TTL expiry (with configurable cacheTTL), and full cache invalidation via InvalidateAll(). No further work needed.

## Summary The ROADMAP (Phase 1.4) specifies an in-memory cache with 30-second TTL using `sync.RWMutex` and cache invalidation on write operations. The cache logic in `internal/gitea/client.go` has no dedicated tests — a TTL regression or invalidation bug would cause stale data to be served after label assignments or review submissions. ## What to Do 1. Add tests in `internal/gitea/client_test.go` for: - Cache hit: call a read function twice with the same key, verify only one HTTP call is made to the mock server - Cache miss after TTL: manipulate the cache entry timestamp to simulate expiry, verify the next read triggers a fresh HTTP call - Cache invalidation: call `InvalidateAll()` or a write operation (e.g., `ApplyLabel()`), verify the next read fetches fresh data 2. Use a mock HTTP server to count real API calls ## Acceptance Criteria - `go test ./internal/gitea/...` passes with the new tests - TTL expiry is tested (can use a very short TTL or manipulate the internal timestamp) - Write operations correctly invalidate cache entries - No real Gitea API calls in tests ## Roadmap Reference Phase 1.4 — Gitea Aggregation Layer: in-memory cache with 30s TTL --- **Closing:** `TestCache`, `TestCacheExpiry`, and `TestInvalidateAll` in `internal/gitea/client_test.go` already cover all acceptance criteria: cache hit/miss, TTL expiry (with configurable `cacheTTL`), and full cache invalidation via `InvalidateAll()`.
