From 4e5015a22c2f93166e00e4e8ebfe7250ff9286de Mon Sep 17 00:00:00 2001 From: Fred Amaral Date: Thu, 26 Mar 2026 19:35:36 -0300 Subject: [PATCH] refactor: harden core infrastructure, tenant-manager, and runtime packages Applies comprehensive code review findings across all non-systemplane packages. Tenant-manager: - TenantAwareLogger.With/WithGroup now preserve tenant_id injection chain - ShouldSchedule adds hasClient guard and uses deterministic time source - Cert path traversal prevention via ValidateCertPath in core/security.go - TLS/SSL runtime warnings for insecure configurations - Postgres Close() harmonized to snapshot-then-cleanup pattern - SetAuthVerified helper and migration guide for upstream auth assertion - Tenant ID removed from 404 responses to prevent enumeration - HandleFetchError logs close errors instead of swallowing them - New unit tests for configfetch and revalidation packages - Dead logcompat methods removed Core infrastructure: - Panic recovery consolidated to single logPanicWithStack path - Dead logPanic wrapper removed - CORS helper renamed for clarity (isUnrestrictedCORSOrigin) - requestScopedLogger nil guard added - Circuitbreaker nil guard symmetry restored - snapshotConnectState precondition documented - Various test improvements (serial execution docs, edge cases) Build/docs: - REVIEW.md removed (superseded by review process) - MIGRATION_MAP.md updated X-Lerian-Ref: 0x1 --- .golangci.yml | 8 + MIGRATION_MAP.md | 1003 ++--------------- Makefile | 22 +- REVIEW.md | 388 ------- commons/circuitbreaker/healthchecker.go | 65 +- commons/circuitbreaker/manager.go | 135 +-- commons/mongo/mongo.go | 72 +- commons/mongo/mongo_test.go | 394 ++++--- commons/net/http/error.go | 14 +- commons/net/http/handler.go | 17 +- commons/net/http/handler_helpers.go | 19 + commons/net/http/matcher_response.go | 25 +- commons/net/http/response.go | 20 +- commons/net/http/withBasicAuth.go | 47 +- commons/net/http/withCORS.go | 123 +- commons/net/http/withLogging_middleware.go | 25 +- commons/net/http/withTelemetry.go | 27 +- commons/net/http/withTelemetry_helpers.go | 38 + commons/opentelemetry/metrics/builders.go | 101 +- commons/opentelemetry/metrics/metrics.go | 8 +- commons/opentelemetry/otel.go | 85 +- commons/outbox/config.go | 2 +- commons/outbox/dispatcher.go | 6 +- commons/outbox/postgres/db.go | 34 +- commons/outbox/postgres/db_test.go | 166 ++- commons/postgres/postgres.go | 127 ++- commons/postgres/postgres_test.go | 53 +- commons/rabbitmq/rabbitmq.go | 191 ++-- commons/redis/redis.go | 54 +- commons/redis/redis_test.go | 62 +- commons/runtime/goroutine.go | 19 +- commons/runtime/recover.go | 45 +- commons/runtime/recover_helpers.go | 49 + commons/runtime/recover_test.go | 6 +- commons/server/shutdown.go | 168 +-- commons/tenant-manager/core/security.go | 84 ++ .../internal/configfetch/configfetch.go | 43 + .../internal/configfetch/configfetch_test.go | 26 + .../internal/logcompat/logger.go | 123 +- .../internal/revalidation/revalidation.go | 64 ++ .../revalidation/revalidation_test.go | 189 ++++ commons/tenant-manager/log/tenant_logger.go | 17 +- .../tenant-manager/log/tenant_logger_test.go | 12 +- commons/tenant-manager/middleware/tenant.go | 29 +- .../middleware/tenant_errors.go | 4 +- .../tenant-manager/middleware/tenant_test.go | 131 +++ commons/tenant-manager/mongo/manager.go | 345 +++--- commons/tenant-manager/mongo/manager_test.go | 16 +- commons/tenant-manager/postgres/manager.go | 78 +- commons/tenant-manager/rabbitmq/manager.go | 274 +++-- .../tenant-manager/rabbitmq/manager_test.go | 8 +- 51 files changed, 2327 insertions(+), 2734 deletions(-) delete mode 100644 REVIEW.md create mode 100644 commons/net/http/handler_helpers.go create mode 100644 commons/runtime/recover_helpers.go create mode 100644 commons/tenant-manager/core/security.go create mode 100644 commons/tenant-manager/internal/configfetch/configfetch.go create mode 100644 commons/tenant-manager/internal/configfetch/configfetch_test.go create mode 100644 commons/tenant-manager/internal/revalidation/revalidation.go create mode 100644 commons/tenant-manager/internal/revalidation/revalidation_test.go diff --git a/.golangci.yml b/.golangci.yml index fe97dce5..7906fa8a 100644 --- a/.golangci.yml +++ b/.golangci.yml @@ -1,6 +1,10 @@ version: "2" run: tests: false + skip-dirs: + - docs/codereview + skip-files: + - docs/codereview/.*\.go linters: enable: # --- Existing linters --- @@ -156,6 +160,8 @@ linters: - path: (.+)\.go$ text: parameter .* always receives paths: + - docs/codereview$ + - docs/codereview/ - third_party$ - builtin$ - examples$ @@ -166,6 +172,8 @@ formatters: exclusions: generated: lax paths: + - docs/codereview$ + - docs/codereview/ - third_party$ - builtin$ - examples$ diff --git a/MIGRATION_MAP.md b/MIGRATION_MAP.md index 1fc97af0..1442317b 100644 --- a/MIGRATION_MAP.md +++ b/MIGRATION_MAP.md @@ -1,964 +1,87 @@ -# lib-commons Migration Map (v3 -> v4) +# MIGRATION_MAP -This document maps notable `lib-commons/v3` APIs to the unified `lib-commons/v4` APIs.

Any downstream consumer that unmarshals error responses with `Code` as a string type will break. Callers must update their response parsing structs to use `int` (or a numeric JSON type) for the `code` field. - -### Proxy - -| v3 | v4 | -|----|----| -| `ServeReverseProxy(target, res, req)` | `ServeReverseProxy(target, policy, res, req) error` | - -New: `DefaultReverseProxyPolicy()`, `ReverseProxyPolicy` struct with SSRF protection. - -### Pagination (v4 refinement) - -| v4 (previous) | v4 (current) | -|---|---| -| `EncodeTimestampCursor(time, uuid) string` | `EncodeTimestampCursor(time, uuid) (string, error)` | -| `EncodeSortCursor(col, val, id, next) string` | `EncodeSortCursor(col, val, id, next) (string, error)` | -| `CalculateSortCursorPagination(...)

In v4, negative offsets are silently coerced to `DefaultOffset=0` instead of returning an error. This tradeoff avoids breaking callers that relied on the previous behavior and preserves backward compatibility. However, callers should validate offsets before calling pagination functions (e.g., reject negative offsets at the handler level) since the pagination codepaths that previously returned `ErrOffsetMustBePositive` will now silently accept any negative value. - -**Migration note (cursor/sort):** The cursor encode functions now return errors. The `Order` type is removed; use the `SortDirASC`/`SortDirDESC` constants directly. Note the **case change** from lowercase `"asc"`/`"desc"` to uppercase `"ASC"`/`"DESC"` — any consumer that stores or compares these values must be updated. - -New pagination defaults in `constants/pagination.go`: `DefaultLimit=20`, `DefaultOffset=0`, `MaxLimit=200`. - -### Handler - -| v4 (previous) | v4 (current) | -|---|---| -| `Ping` handler returns `"healthy"` | `Ping` handler returns `"pong"` | - -**Migration note:** Any health check monitor that string-matches the response body for `"healthy"` must be updated.

Previously, whitespace was silently accepted. In v4, whitespace is trimmed but non-UUID values are rejected with an error (`"invalid tenant id format"` from `ApplyTenant`, `ErrDefaultTenantIDInvalid` from `NewSchemaResolver`).

Tenant client caching remains available through exported cache APIs** - -| v3 | v4 | -|---|---| -| cache package exposed at `tenant-manager/cache` | still available at `tenant-manager/cache` | -| `client.WithCache(...)` / `client.WithCacheTTL(...)` | still supported | -| per-call cache bypass | `client.WithSkipCache()` | -| cache eviction | `(*Client).InvalidateConfig(ctx, tenantID, service) error` | - -**3. S3 function signature changes** - -Three S3 functions now return `(string, error)` instead of `string` to support delimiter validation: - -| v3 | v4 | -|---|---| -| `s3.GetObjectStorageKey(tenantID, key) string` | `s3.GetObjectStorageKey(tenantID, key) (string, error)` | -| `s3.GetObjectStorageKeyForTenant(ctx, key) string` | `s3.GetObjectStorageKeyForTenant(ctx, key) (string, error)` | -| `s3.StripObjectStoragePrefix(tenantID, prefixedKey) string` | `s3.StripObjectStoragePrefix(tenantID, prefixedKey) (string, error)` | - -**4. Valkey function signature changes** - -Five Valkey functions now return `(string, error)` instead of `string` to support delimiter validation: - -| v3 | v4 | -|---|---| -| `valkey.GetKey(tenantID, key) string` | `valkey.GetKey(tenantID, key) (string, error)` | -| `valkey.GetKeyFromContext(ctx, key) string` | `valkey.GetKeyFromContext(ctx, key) (string, error)` | -| `valkey.GetPattern(tenantID, pattern) string` | `valkey.GetPattern(tenantID, pattern) (string, error)` | -| `valkey.GetPatternFromContext(ctx, pattern) string` | `valkey.GetPatternFromContext(ctx, pattern) (string, error)` | -| `valkey.StripTenantPrefix(tenantID, prefixedKey) string` | `valkey.StripTenantPrefix(tenantID, prefixedKey) (string, error)` | - -**5. `hasUpstreamAuthAssertion` behavioral change** - -| Behavior | v4 | -|----------|-----| -| Auth assertion via HTTP header | The middleware no longer checks the `X-User-ID` HTTP header for auth assertion (headers are client-spoofable). Only `c.Locals("user_id")` set by upstream lib-auth middleware is checked. | - -**Migration note:** Applications relying on the `X-User-ID` header for auth assertion must ensure upstream auth middleware sets the Fiber local `user_id` value instead. The header path was removed because HTTP headers are client-spoofable and cannot be trusted for authorization decisions. - -**6. `isPublicPath` boundary-aware matching** - -| Behavior | v3 | v4 | -|----------|---|---| -| `isPublicPath` matching | `strings.HasPrefix(path, prefix)` | `path == prefix \|\| strings.HasPrefix(path, prefix+"/")` | - -**Before:** `/healthy` matched public path `/health` because `strings.HasPrefix("/healthy", "/health")` is true. - -**After:** `/healthy` does **not** match public path `/health`. Only exact matches (`/health`) or sub-paths (`/health/live`) match. - -**Migration note:** Services using `WithPublicPaths()` that relied on the previous prefix-only matching behavior may need to adjust their configured paths. For example, if a service had `WithPublicPaths("/health")` and expected `/healthz` to be treated as public, it must now explicitly add `/healthz` to the public paths list. This change prevents unintended route matching where a public path prefix accidentally exempted unrelated endpoints from tenant resolution. - -**7. PostgreSQL SSL default changed** - -| Behavior | v3 | v4 | -|----------|---|---| -| `buildConnectionString` SSL mode | `sslmode=disable` | `sslmode=prefer` | - -Connections will now attempt TLS when available with graceful fallback to plaintext. Set `SSLMode: "disable"` explicitly in `PostgreSQLConfig` to restore the previous behavior. - -**8. Tenant ID format validation** - -| Behavior | v4 | -|----------|-----| -| Tenant ID format | Middleware and consumer now validate tenant IDs against `^[a-zA-Z0-9][a-zA-Z0-9_-]*$` with a 256-character limit. | - -Tenant IDs containing dots, spaces, or special characters will be rejected. This applies to both `TenantMiddleware` and `MultiTenantConsumer` tenant lifecycle management. - -**9. `WorkersPerQueue` default changed** - -| Config field | v3 | v4 | -|---|---|---| -| `DefaultMultiTenantConfig().WorkersPerQueue` | `1` | `0` | - -The field is reserved for future use and currently a no-op. - -**10. Client error message format** - -| Behavior | v4 | -|----------|-----| -| Error messages from tenant manager HTTP client | No longer include raw response body content. Response bodies are now logged separately via `truncateBody` for security. | - -**Migration note:** Any error-message parsing that relied on response body content embedded in the error string will no longer match. Use structured logging output to inspect response bodies. - -#### Behavioral changes in outbox/tenant.go - -- `ContextWithTenantID` now writes to both the new `core.tenantIDKey` context key AND the legacy `TenantIDContextKey` for backward compatibility. -- `TenantIDFromContext` reads the new `core.tenantIDKey` first, then falls back to the legacy key. -- Tenant IDs with leading/trailing whitespace are now **rejected** (v3 behavior was to silently trim). Callers must pre-trim tenant IDs. - ---- - -## Deleted files in v4 - -The following files were removed during v4 consolidation: - -| File | Reason | -|------|--------| -| `mk/tests.mk` | test targets inlined into main Makefile | -| `commons/logging/sanitizer.go` + `sanitizer_test.go` | package removed;
