-```text -lib-commons/ -├── commons/ # All library packages -│ ├── {package}/ # Feature package -│ │ ├── {package}.go # Main implementation -│ │ ├── {package}_test.go # Unit tests -│ │ └── doc.go # Package documentation (optional) -│ ├── context.go # Root-level utilities -│ ├── errors.go # Error definitions -│ └── utils.go # Utility functions -├── docs/ # Documentation -├── scripts/ # Build/test scripts -└── go.mod # Module definition -``` - -### Package Design Principles - -1. **Single Responsibility**: Each package should have one clear purpose -2. **Minimal Dependencies**: Packages should minimize external dependencies -3. **Interface-Driven**: Define interfaces for testability and flexibility -4. **Zero Business Logic**: This is a utility library - no domain/business logic - -### Naming Conventions - -| Type | Convention | Example | -|------|------------|---------| -| Package | lowercase, single word preferred | `postgres`, `redis`, `poolmanager` | -| Files | snake_case matching content | `pool_manager_pg.go` | -| Public Functions | PascalCase, descriptive | `NewPostgresConnection` | -| Private Functions | camelCase | `validateConfig` | -| Interfaces | -er suffix or descriptive | `Logger`, `ConnectionPool` | -| Constants | PascalCase or UPPER_SNAKE_CASE | `DefaultTimeout`, `MAX_RETRIES` | - ---- - -## Code Conventions - -### Go Version - -- **Minimum**: Go 1.24.0 -- Keep `go.mod` updated with latest stable Go version - -### Imports Organization - -```go -import ( - // Standard library - "context" - "fmt" - "time" - - // Third-party packages - "github.com/jackc/pgx/v5" - "go.uber.org/zap" - - // Internal packages - "github.com/LerianStudio/lib-commons/v2/commons/log" -) -``` - -### Function Design - -1. **Context First**: Functions that may block should accept `context.Context` as first parameter -2. **Options Pattern**: Use functional options for configurable constructors -3. **Error Last**: Return errors as the last return value -4. **Named Returns**: Avoid named returns except for documentation - -```go -// Good -func NewClient(ctx context.Context, opts ...Option) (*Client, error) - -// Avoid -func NewClient(opts ...Option) (client *Client, err error) -``` - -### Struct Design - -```go -type Config struct { - Host string `json:"host"` - Port int `json:"port"` - Timeout time.Duration `json:"timeout"` - MaxConns int `json:"max_conns"` -} - -func (c *Config) Validate() error { - if c.Host == "" { - return ErrEmptyHost - } - return nil -} -``` - -### Constants and Variables - -```go -const ( - DefaultTimeout = 30 * time.Second - DefaultMaxConns = 10 -) - -var ( - ErrNotFound = errors.New("not found") - ErrInvalidInput = errors.New("invalid input") -) -``` - ---- - -## Error Handling - -### Error Definition - -1. **Sentinel Errors**: Define package-level errors for expected conditions -2. **Error Wrapping**: Use `fmt.Errorf` with `%w` for context -3. **Custom Types**: Use custom error types when additional context is needed - -```go -var ( - ErrConnectionFailed = errors.New("connection failed") - ErrTenantNotFound = errors.New("tenant not found") -) - -// Wrapping -return fmt.Errorf("failed to connect to %s: %w", host, err) - -// Custom type -type ValidationError struct { - Field string - Message string -} - -func (e *ValidationError) Error() string { - return fmt.Sprintf("validation failed for %s: %s", e.Field, e.Message) -} -``` - -### Error Handling Rules - -1. **NEVER use panic()** - Always return errors -2. **NEVER ignore errors** - Handle or propagate all errors -3. **Log at boundaries** - Log errors at service boundaries, not in library code -4. **Provide context** - Wrap errors with meaningful context - -```go -// Good -if err != nil { - return fmt.Errorf("failed to execute query: %w", err) -} - -// Bad - panics -if err != nil { - panic(err) -} - -// Bad - ignores error -result, _ := doSomething() -``` - ---- - -## Testing Requirements - -### Coverage Requirements - -- **Minimum Coverage**: 80% for new packages -- **Critical Paths**: 100% coverage for error handling paths -- **Run Coverage**: `make cover` - -### Test File Naming - -| Type | Pattern | Example | -|------|---------|---------| -| Unit Tests | `{file}_test.go` | `config_test.go` | -| Integration | `{file}_integration_test.go` | `postgres_integration_test.go` | -| Benchmarks | In `_test.go` files | `BenchmarkXxx` | - -### Test Patterns - -```go -func TestConfig_Validate(t *testing.T) { - tests := []struct { - name string - config Config - wantErr bool - }{ - { - name: "valid config", - config: Config{Host: "localhost", Port: 5432}, - wantErr: false, - }, - { - name: "empty host", - config: Config{Host: "", Port: 5432}, - wantErr: true, - }, - } - - for _, tt := range tests { - t.Run(tt.name, func(t *testing.T) { - err := tt.config.Validate() - if (err != nil) != tt.wantErr { - t.Errorf("Validate() error = %v, wantErr %v", err, tt.wantErr) - } - }) - } -} -``` - -### Test Data - -- Use realistic but fake data (e.g., `"pass"`, `"secret"` for passwords in tests) -- Never use real credentials in tests -- Use test fixtures for complex data structures - -### Mocking - -- Use `go.uber.org/mock` for interface mocking -- Define interfaces at point of use for testability -- Prefer dependency injection over global state - ---- - -## Documentation Standards - -### Package Documentation - -Every package MUST have a `doc.go` file or package comment: - -```go -// Package postgres provides PostgreSQL connection management utilities. -// -// It supports connection pooling, migrations, and read-replica configurations -// for high-availability deployments. -package postgres -``` - -### Function Documentation - -Public functions MUST have documentation: - -```go -// Connect establishes a connection to the PostgreSQL database. -// It validates the configuration before attempting to connect. -// -// Returns an error if the configuration is invalid or connection fails. -func (c *Client) Connect(ctx context.Context) error { -``` - -### README Updates - -- Update `README.md` API Reference when adding public APIs -- Include usage examples for new packages - ---- - -## Dependencies - -### Allowed Dependencies - -| Category | Allowed Packages | -|----------|-----------------| -| Database | `pgx/v5`, `mongo-driver`, `go-redis/v9` | -| Messaging | `amqp091-go` | -| Logging | `zap`, internal `log` package | -| Testing | `testify`, `gomock`, `miniredis` | -| Observability | `opentelemetry/*` | -| Utilities | `google/uuid`, `shopspring/decimal` | - -### Forbidden Dependencies - -- `io/ioutil` - Deprecated, use `io` and `os` -- Direct database drivers without connection pooling -- Logging packages other than `zap` (use internal wrapper) - -### Adding Dependencies - -1. Check if functionality exists in standard library -2. Check if existing dependency provides the functionality -3. Evaluate package maintenance and security -4. Add to `go.mod` with specific version - ---- - -## Security - -### Credential Handling - -1. **Never hardcode credentials** - Use environment variables -2. **Never log credentials** - Use obfuscation for sensitive fields -3. **Mask in errors** - Never include credentials in error messages - -```go -// Good - mask DSN -func MaskDSN(dsn string) string { - return regexp.MustCompile(`password=[^\s]+`).ReplaceAllString(dsn, "password=***") -} - -// Bad - exposes password -log.Errorf("failed to connect: %s", dsn) -``` - -### Input Validation - -1. Validate all external inputs -2. Use parameterized queries - never string concatenation -3. Sanitize user-provided identifiers - -### Environment Variables - -- Use `SECURE_LOG_FIELDS` for field obfuscation -- Document required environment variables -- Provide sensible defaults where safe - ---- - -## DevOps - -### Linting - -- **Tool**: `golangci-lint` v2 -- **Config**: `.golangci.yml` -- **Run**: `make lint` - -### Formatting - -- **Tool**: `gofmt` -- **Run**: `make format` -- All code MUST be formatted before commit - -### Testing Commands - -```bash -make test # Run all tests -make cover # Generate coverage report -make lint # Run linters -make format # Format code -make sec # Security scan with gosec -make tidy # Clean up go.mod -``` - -### Git Hooks - -- Pre-commit hooks available in `.githooks/` -- Setup: `make setup-git-hooks` -- Verify: `make check-hooks` - -### CI/CD - -- All PRs must pass linting -- All PRs must pass tests -- Coverage must not decrease -- Security scan must pass - ---- - -## Checklist - -Before submitting code: - -- [ ] Code follows naming conventions -- [ ] All public APIs are documented -- [ ] Tests achieve 80%+ coverage -- [ ] No panics - all errors handled -- [ ] No hardcoded credentials -- [ ] `make lint` passes -- [ ] `make test`

17 00:00:00 2001 From: Jefferson Rodrigues Date: Fri, 23 Jan 2026 00:48:21 -0300 Subject: [PATCH 002/118] feat(tenant-manager): refactor MongoPool to reuse MongoConnection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Refactor MongoPool to use MongoConnection from commons/mongo instead of duplicating connection logic - Add WithMongoLogger option to pass logger to MongoConnection - Add AuthSource and DirectConnection fields to MongoDBConfig for MongoDB authentication and replica set support - Add MaxPoolSize field to MongoDBConfig for connection pool sizing - Update buildMongoURI to support authSource and directConnection params 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 ---

Use separate replica connection when available, falling back to primary. Remove SchemaNameFromTenantID and setSearchPath methods as schema is now provided directly by Pool Manager.

006/118] refactor(tenant-manager): rename pool terminology to manager Rename all Pool/pool identifiers to Manager/manager across the tenant-manager package for clarity. File renames: pool.go to postgres.go, pool_test.go to postgres_test.go, rabbitmq_pool.go to rabbitmq.go. Type renames: Pool to PostgresManager, MongoPool to MongoManager, RabbitMQPool to RabbitMQManager, ErrPoolClosed to ErrManagerClosed.

Key changes: - Add knownTenants map to track discovered tenants without connecting - Implement ensureConsumerStarted() for on-demand consumer spawning - Add exponential backoff for connection retries (5s, 10s, 20s, 40s) - Add per-tenant retry state and degraded tenant tracking - Enhance Stats() API with ConnectionMode, KnownTenants, PendingTenants, DegradedTenants - Add tenant ID validation with regex whitelist - Add URL encoding for tenant IDs and service names in HTTP client - Add response body size limits (10MB) for DoS prevention - Add 100% OpenTelemetry instrumentation with per-iteration spans - Add comprehensive test suite (133 test cases, 95% coverage) Breaking changes: - Startup behavior: Run() no longer blocks on tenant connections - First message per tenant incurs connection establishment latency (~200-500ms) See MIGRATION_GUIDE.md for upgrade instructions.

Guide: Multi-Tenant Consumer v2 to v3 + +This guide covers the breaking changes introduced in lib-commons v3.0.0 for the multi-tenant consumer. + +## Summary of Changes + +The `MultiTenantConsumer` now operates in **lazy mode** by default. This means: + +- `Run()` discovers tenants but does NOT start consumers (startup time < 1 second) +- Consumers are spawned **on-demand** via `EnsureConsumerStarted()` +- Connection failures use **exponential backoff** (5s, 10s, 20s, 40s max) +- Tenants are marked as **degraded** after 3 consecutive failures +- `Stats()` returns enhanced metadata (ConnectionMode, KnownTenants, PendingTenants, DegradedTenants) + +## Breaking Changes + +### 1. MultiTenantConsumerStats has new fields + +**Before (v2):** + +```go +type MultiTenantConsumerStats struct { + ActiveTenants int `json:"activeTenants"` + TenantIDs []string `json:"tenantIds"` + RegisteredQueues []string `json:"registeredQueues"` + Closed bool `json:"closed"` +} +``` + +**After (v3):** + +```go +type MultiTenantConsumerStats struct { + ActiveTenants int `json:"activeTenants"` + TenantIDs []string `json:"tenantIds"` + RegisteredQueues []string `json:"registeredQueues"` + Closed bool `json:"closed"` + ConnectionMode string `json:"connectionMode"` + KnownTenants int `json:"knownTenants"` + KnownTenantIDs []string `json:"knownTenantIds"` + PendingTenants int `json:"pendingTenants"` + PendingTenantIDs []string `json:"pendingTenantIds"` + DegradedTenants []string `json:"degradedTenants"` +} +``` + +**Action required:** If your code structurally compares or unmarshals `MultiTenantConsumerStats`, update it to handle the new fields. + +### 2. Run() no longer starts consumers + +**Before (v2):** `Run()` discovered tenants and immediately started consumer goroutines for each. + +**After (v3):** `Run()` discovers tenants (populates `knownTenants`) but does NOT start consumers. You must call `EnsureConsumerStarted()` to spawn consumers on-demand. + +**Action required:** Add `EnsureConsumerStarted()` calls at the point where your service needs to start consuming for a tenant. Common integration points: + +```go +// Example: In a message router that receives tenant-specific triggers +func (r *Router) HandleTenantMessage(ctx context.Context, tenantID string) { + // Ensure the consumer is running for this tenant + r.consumer.EnsureConsumerStarted(ctx, tenantID) +} +``` + +### 3. Connection retry behavior changed + +**Before (v2):** Fixed 5-second retry delay on all connection failures. + +**After (v3):** Exponential backoff per tenant: 5s, 10s, 20s, 40s (capped). Tenants are marked degraded after 3 consecutive failures. + +**Action required:** No code changes needed. The new behavior is backward-compatible in terms of API. Monitor the `IsDegraded()` method or `Stats().DegradedTenants` for tenant health visibility. + +## New Features + +### On-Demand Consumer Spawning + +```go +// Thread-safe, exactly-once guarantee +consumer.EnsureConsumerStarted(ctx, "tenant-123") +``` + +### Degraded Tenant Detection + +```go +if consumer.IsDegraded("tenant-123") { + // Handle degraded tenant (e.g., alert, skip, retry later) +} +``` + +### Enhanced Stats + +```go +stats := consumer.Stats() +// stats.ConnectionMode = "lazy" +// stats.KnownTenants = 50 (discovered but not necessarily consuming) +// stats.ActiveTenants = 10 (actually consuming) +// stats.PendingTenants = 40 (known but not yet consuming) +// stats.DegradedTenants = ["tenant-x"] (connection failures >= 3) +``` + +### Metric Constants + +```go +// Use these constants when instrumenting with Prometheus +tenantmanager.MetricTenantConnectionsTotal // "tenant_connections_total" +tenantmanager.MetricTenantConnectionErrors // "tenant_connection_errors_total" +tenantmanager.MetricTenantConsumersActive // "tenant_consumers_active" +tenantmanager.MetricTenantMessageProcessed // "tenant_messages_processed_total" +``` + +## Recommended Migration Steps + +1. Update `go.mod` to use lib-commons v3.0.0 +2. Review any code that directly inspects `MultiTenantConsumerStats` fields +3. Add `EnsureConsumerStarted()` calls at your service's message entry points +4. (Optional) Add monitoring for `IsDegraded()` or `Stats().DegradedTenants` +5.

This means: - -- `Run()` discovers tenants but does NOT start consumers (startup time < 1 second) -- Consumers are spawned **on-demand** via `EnsureConsumerStarted()` -- Connection failures use **exponential backoff** (5s, 10s, 20s, 40s max) -- Tenants are marked as **degraded** after 3 consecutive failures -- `Stats()` returns enhanced metadata (ConnectionMode, KnownTenants, PendingTenants, DegradedTenants) - -## Breaking Changes - -### 1. MultiTenantConsumerStats has new fields - -**Before (v2):** - -```go -type MultiTenantConsumerStats struct { - ActiveTenants int `json:"activeTenants"` - TenantIDs []string `json:"tenantIds"` - RegisteredQueues []string `json:"registeredQueues"` - Closed bool `json:"closed"` -} -``` - -**After (v3):** - -```go -type MultiTenantConsumerStats struct { - ActiveTenants int `json:"activeTenants"` - TenantIDs []string `json:"tenantIds"` - RegisteredQueues []string `json:"registeredQueues"` - Closed bool `json:"closed"` - ConnectionMode string `json:"connectionMode"` - KnownTenants int `json:"knownTenants"` - KnownTenantIDs []string `json:"knownTenantIds"` - PendingTenants int `json:"pendingTenants"` - PendingTenantIDs []string `json:"pendingTenantIds"` - DegradedTenants []string `json:"degradedTenants"` -} -``` - -**Action required:** If your code structurally compares or unmarshals `MultiTenantConsumerStats`, update it to handle the new fields. - -### 2. Run() no longer starts consumers - -**Before (v2):** `Run()` discovered tenants and immediately started consumer goroutines for each. - -**After (v3):** `Run()` discovers tenants (populates `knownTenants`) but does NOT start consumers. You must call `EnsureConsumerStarted()` to spawn consumers on-demand. - -**Action required:** Add `EnsureConsumerStarted()` calls at the point where your service needs to start consuming for a tenant. Common integration points: - -```go -// Example: In a message router that receives tenant-specific triggers -func (r *Router) HandleTenantMessage(ctx context.Context, tenantID string) { - // Ensure the consumer is running for this tenant - r.consumer.EnsureConsumerStarted(ctx, tenantID) -} -``` - -### 3. Connection retry behavior changed - -**Before (v2):** Fixed 5-second retry delay on all connection failures. - -**After (v3):** Exponential backoff per tenant: 5s, 10s, 20s, 40s (capped). Tenants are marked degraded after 3 consecutive failures. - -**Action required:** No code changes needed. The new behavior is backward-compatible in terms of API. Monitor the `IsDegraded()` method or `Stats().DegradedTenants` for tenant health visibility. - -## New Features - -### On-Demand Consumer Spawning - -```go -// Thread-safe, exactly-once guarantee -consumer.EnsureConsumerStarted(ctx, "tenant-123") -``` - -### Degraded Tenant Detection - -```go -if consumer.IsDegraded("tenant-123") { - // Handle degraded tenant (e.g., alert, skip, retry later) -} -``` - -### Enhanced Stats - -```go -stats := consumer.Stats() -// stats.ConnectionMode = "lazy" -// stats.KnownTenants = 50 (discovered but not necessarily consuming) -// stats.ActiveTenants = 10 (actually consuming) -// stats.PendingTenants = 40 (known but not yet consuming) -// stats.DegradedTenants = ["tenant-x"] (connection failures >= 3) -``` - -### Metric Constants - -```go -// Use these constants when instrumenting with Prometheus -tenantmanager.MetricTenantConnectionsTotal // "tenant_connections_total" -tenantmanager.MetricTenantConnectionErrors // "tenant_connection_errors_total" -tenantmanager.MetricTenantConsumersActive // "tenant_consumers_active" -tenantmanager.MetricTenantMessageProcessed // "tenant_messages_processed_total" -``` - -## Recommended Migration Steps - -1. Update `go.mod` to use lib-commons v3.0.0 -2. Review any code that directly inspects `MultiTenantConsumerStats` fields -3. Add `EnsureConsumerStarted()` calls at your service's message entry points -4. (Optional) Add monitoring for `IsDegraded()` or `Stats().DegradedTenants` -5.

019/118] fix(tenant-manager): improve connection safety, avoid Fatal calls, and add absent-sync threshold Replace Logger.Fatal with Logger.Error in postgres to prevent process crashes. Fix mutex lock contention in MongoManager.createClient by releasing lock before error returns. Add absentSyncsBeforeRemoval to prevent premature tenant removal from a single sync miss.

This ensures that when operators change pool settings via the tenant-manager, the changes propagate to all consuming services within ~30 seconds without requiring a container restart. Previously, pool settings were only applied at connection creation time. Services using PostgresManager directly (without MultiTenantConsumer) would never pick up settings changes. Key changes: - Add lastSettingsCheck per-tenant tracking in PostgresManager - Add async revalidateSettings goroutine (fire-and-forget, does not block GetConnection) - Add WithSettingsCheckInterval functional option (default: 30s) - Add logging to ApplyConnectionSettings for observability - Clean up lastSettingsCheck on CloseConnection/Close - Add 8 new tests covering revalidation, interval enforcement, failure resilience, and cleanup Go's sql.DB.SetMaxOpenConns/SetMaxIdleConns are thread-safe and take effect immediately for new connections without disrupting active ones. --- commons/tenant-manager/postgres.go | 93 ++++++- commons/tenant-manager/postgres_test.go | 307 ++++++++++++++++++++++++ 2 files changed, 392 insertions(+), 8 deletions(-) diff --git a/commons/tenant-manager/postgres.go b/commons/tenant-manager/postgres.go index 7996ae83..264731f2 100644 --- a/commons/tenant-manager/postgres.go +++ b/commons/tenant-manager/postgres.go @@ -21,6 +21,16 @@ import ( // Kept short to avoid blocking requests when a cached connection is stale. const pingTimeout = 3 * time.Second +// defaultSettingsCheckInterval is the default interval between periodic +// connection pool settings revalidation checks.

052/118] fix(secretsmanager): use typed AWS errors and validate credential fields Replace brittle strings.Contains error classification with errors.As using smtypes.ResourceNotFoundException and smithy.APIError for type-safe AWS error handling. Add post-unmarshal validation that rejects incomplete credentials (empty ClientID, ClientSecret, or TokenURL) with ErrM2MInvalidCredentials. Migrate all test assertions from assert.Contains to require.ErrorIs with sentinel errors, and update mock to return real AWS SDK typed errors.

Update all direct and transitive dependencies. * chore: modernize build system, linting, and release configuration Replace legacy Makefile/mk includes with unified build targets supporting gotestsum, coverage, integration tests, and LOW_RESOURCE mode. Add 30+ linters across safety, quality, and zero-issue tiers to golangci-yml. Convert goreleaser to library-only mode (skip binary builds). Remove legacy githooks and license-header script in favor of CI-driven checks. * docs: update license, changelog, and project documentation for v4 Switch to Apache-2.0 license. Reset CHANGELOG for the v4 generation. Rewrite README with current package inventory and API surface. Add AGENTS.md for coding-agent guidance, MIGRATION_MAP.md for v2-to-v4 symbol mapping, and REVIEW.md for audit notes. * refactor(constants): expand shared constants with OTEL attributes and sanitization Add SanitizeMetricLabel for OTEL label safety, ErrorResponse constants, expanded header constants (X-Idempotency-Replayed, X-Request-ID), and structured OTEL attribute keys. Remove license headers, add doc.go. * refactor(log): rewrite Logger interface with structured fields and nil-safe adapters Replace printf-style logging with 5-method Logger interface (Log, With, WithGroup, Enabled, Sync) and typed Field constructors. Add GoLogger stdlib adapter with CWE-117 log-injection prevention and sanitizer (SafeError, SanitizeExternalResponse). Rewrite zap adapter to implement new interface with OTEL bridge support and atomic level control. * refactor: modernize core helpers with explicit error returns and nil safety Rewrite root helpers (app, context, errors, os, time, string, utils) to use v4 Logger interface with explicit error returns. Add context cloning and example tests. Harden crypto with credential-safe String/GoString redaction and nil-receiver guards. Expand security sensitive-field detection with map-based lookup. Add doc.go across packages. * feat: add resilience and safety packages Introduce assert (production-safe assertions with telemetry), backoff (exponential with jitter), runtime (panic recovery, safe goroutines, panic metrics), safe (panic-free math/regex/slice), errgroup (goroutine coordination with panic recovery), cron (expression parsing), and jwt (HMAC signing/verification with time-claim validation). Add internal test helpers. * refactor(opentelemetry): rewrite telemetry with Redactor and metrics factory Replace FieldObfuscator with Redactor/RedactionRule pattern for span attribute redaction. Add RedactingAttrBagSpanProcessor for automatic sensitive data masking. Introduce MetricsFactory with fluent builders (Counter, Gauge, Histogram) and NopFactory for tests. Add system metrics (goroutines, memory, GC). Remove legacy queue trace tests, add v2 compatibility tests and examples. Convenience recorders no longer take positional org/ledger args. * refactor(data): modernize Postgres, Mongo, Redis, and RabbitMQ connectors Postgres: add backoff-based lazy-connect, dbresolver with read replicas, migration support via NewMigrator, and Resolver(ctx) replacing GetDB(). Mongo: add functional options, URI builder, EnsureIndexes, and OTEL spans. Redis: add topology-based Config (standalone/sentinel/cluster), GCP IAM auth, distributed locking via Redsync with LockManager interface, and backoff-based reconnect. RabbitMQ: add context-aware lifecycle methods, DLQ support, and publisher helpers. Remove legacy postgres pagination. Add integration tests and examples across all connectors. * refactor(http): consolidate HTTP helpers with validation, pagination, and SSRF proxy Add ParseAndVerifyTenantScopedID/ResourceScopedID for ownership verification. Add ParseBodyAndValidate, ValidateStruct, and query param validators. Introduce offset/cursor/timestamp/sort pagination APIs with error-returning encode functions. Add ServeReverseProxy with ReverseProxyPolicy for SSRF protection. Add FiberErrorHandler with OTEL span management. Add Redis-backed rate limit storage. Replace individual status helpers with unified ErrorResponse (Code int, Title, Message). Comprehensive test coverage and examples. * refactor(server): implement ServerManager lifecycle with license integration Replace GracefulShutdown with ServerManager supporting chainable config (WithHTTPServer, WithGRPCServer, WithShutdownChannel, WithShutdownTimeout, WithShutdownHook). Add StartWithGracefulShutdownWithError for error returns and ServersStarted channel for test coordination. Rewrite license manager with functional options (WithLogger). Remove legacy grpc_test. Add integration tests and examples. * refactor(circuitbreaker): add preset configs, metrics, and validated Manager Introduce Manager interface with NewManager constructor using functional options. GetOrCreate now returns (CircuitBreaker, error) with config validation. Add preset configs: DefaultConfig, AggressiveConfig, ConservativeConfig, HTTPServiceConfig, DatabaseConfig. Add WithMetricsFactory option for circuit breaker metrics. NewHealthCheckerWithValidation replaces direct construction. Add comprehensive tests, metrics tests, and examples. * refactor(transaction): implement intent-based planning and balance validation Replace monolithic OperateBalances with BuildIntentPlan, ValidateBalanceEligibility, and ApplyPosting three-phase flow. Add typed IntentPlan, Posting, and LedgerTarget. Add ResolveOperation for pending transaction status transitions. Remove positional org/ledger args from all functions. Add comprehensive validation tests and examples. * refactor(tenant-manager): update multi-tenant subsystem for v4 interfaces Migrate all tenant-manager sub-packages to v4 Logger interface. Restructure context package with validation helpers and reduced context_test surface. Add eviction and logcompat internal packages. Update consumer with lazy-mode lifecycle and exponential backoff. Rename resolution functions to generic Resolve interface. Add goroutine leak tests and valkey key tests. * feat(outbox): add transactional outbox pattern and update secrets manager Introduce outbox package for reliable event publishing with transactional guarantees. Update secrets manager M2M credentials to use typed AWS errors and field validation, removing tokenUrl from M2MCredentials. * chore(deps): bump OTEL to 1.42.0, gRPC to 1.79.2, and patch dependencies Notable upgrades: - go.opentelemetry.io/otel 1.40.0 -> 1.42.0 (+ all SDK/contrib modules) - google.golang.org/grpc 1.79.1 -> 1.79.2 - github.com/golang-jwt/jwt/v5 5.3.0 -> 5.3.1 - golang.org/x/net 0.50.0 -> 0.51.0 * ci: bump golangci-lint from v2.4.0 to v2.11.2 for modernize linter support * chore: restore Elastic License 2.0 * docs: create CLAUDE.md as a symlink to AGENTS.md The file was previously ignored but is now tracked to serve as an alias for the AGENTS.md documentation file. This provides an alternative, more specific, entrypoint for the agent-related documentation, improving discoverability. * fix(build): add -p flag for low-resource test mode and support subdirectory git hooks - Introduce LOW_RES_P_FLAG (-p 1) to limit parallel package compilation under LOW_RESOURCE=1, complementing the existing -parallel and -race flags - Rewrite setup-git-hooks to iterate subdirectories under .githooks/, supporting organized hook layouts instead of flat file copies - Update goreleaser comment to reflect lib-commons/v4 module identity * fix(assert): improve test robustness, fix doc example, and remove panic in test helper - Replace panic() in newTestMetricsFactory with require.NoError and accept *testing.T, following the "no panic in tests" convention - Remove duplicate "go.opentelemetry.io/otel/sdk/trace" import; use only the tracesdk alias consistently - Fix flaky TestDateNotInFuture by replacing exact "now" with deterministic now.Add(-time.Second), eliminating timing-dependent assertion - Add negative releaseAmount edge case to TestBalanceSufficientForRelease - Correct doc.go example: file.Read() (nonexistent) -> file.Read(buf) with proper error handling comment * fix(backoff): check context error for zero-duration waits WaitContext previously returned nil for zero or negative durations even when the context was already cancelled. This masked cancellation signals in retry loops where the caller expected a cancelled context to propagate immediately. Now returns ctx.Err() for zero/negative durations, ensuring a cancelled context is never silently ignored. Adds dedicated test case and relaxes CI timing thresholds (10ms -> 200ms, 100ms -> 500ms) to reduce flakiness on resource-constrained runners. * fix(circuitbreaker,crypto): handle all nilable interface kinds in nil checks - Extend isNilListener to handle ptr, slice, map, chan, func, and interface kinds via reflect, preventing panics when a typed-nil value of any nilable kind is passed as a StateChangeListener - Switch crypto logger() to use isNilInterface for typed-nil detection, e.g. (*MyLogger)(nil) now correctly falls back to NopLogger - Migrate crypto tests from ErrorContains string matching to ErrorIs sentinel comparisons for stronger error identity assertions * fix(errgroup): protect logger field with mutex for concurrency safety SetLogger and Go could race when SetLogger was called concurrently with goroutine launches reading the logger. Adds sync.RWMutex around the logger field with a getLogger() accessor used from the recovery path. Also fixes TestWithContext_MultipleErrors_ReturnsFirst: replaces time.Sleep(50ms) ordering hack with explicit channel synchronization, making the test deterministic regardless of scheduler timing. * fix(jwt): preserve numeric fidelity in claims with json.Number decoding json.Unmarshal decodes JSON numbers as float64, which silently loses precision for large Unix timestamps (>2^53). Switch parseClaims to json.Decoder with UseNumber() so numeric claims (iat, exp, nbf) arrive as json.Number, preserving their exact string representation. ValidateTimeClaims already handles json.Number via its toUnixTime helper, so this change is backward-compatible for all downstream consumers that use the typed accessors. * fix(mongo): harden IPv6 detection, sanitize driver errors, and fix TLS defaults IPv6 detection: require 2+ colons in buildHost before bracketing, preventing false positives for simple "host:port" strings that contain exactly one colon. Error sanitization: wrap driver errors through sanitizeDriverError in Ping and Close paths to strip credentials from error messages before they reach logs or telemetry spans. TLS defaults: normalizeTLSDefaults now only sets MinVersion to TLS 1.2 when unspecified (zero value). Explicit versions -- even insecure ones like TLS 1.0 -- are preserved so buildTLSConfig can reject them with a clear validation error rather than silently overwriting the intent. Integration test: handle both bson.M and bson.D index key types returned by different driver versions in EnsureIndexes verification. * fix(constants): make SanitizeMetricLabel rune-aware for UTF-8 safety The byte-length truncation could split multibyte UTF-8 codepoints, producing invalid strings in metric labels. Now converts to []rune only when the byte length exceeds MaxMetricLabelLength (fast path preserved for ASCII-only labels) and truncates by rune count. Adds tests for emoji (4-byte) and CJK (3-byte) multibyte sequences to verify truncation never produces invalid UTF-8. * docs(assert,errgroup,circuitbreaker): align doc comments with implementation - assert/doc.go: fix predicate param names (minVal/maxVal, amount) to match actual signatures; add missing PositiveInt and InRangeInt int variants; fix InitAssertionMetrics param name from metricsFactory to factory - errgroup: fix Go() doc — method is a no-op on nil *Group, not an error return (signature has no return value) * fix(circuitbreaker): detect typed-nil Logger in NewManager and fix IsHealthy docs - Add isNilLogger() reflection helper mirroring the existing isNilListener pattern — catches (*SomeLogger)(nil) values that would panic on first Log call - NewManager now rejects typed-nil loggers with ErrNilLogger - Fix IsHealthy docstring: both StateOpen and StateUnknown are unhealthy (comment previously said only StateOpen) * fix(mongo): harden config normalization, TLS detection, and error classification - normalizeConfig: trim whitespace from URI, Database, and TLS.CACertBase64 so stored values match what validate() checks - buildTLSConfig: malformed CA cert now returns ErrInvalidConfig via configError() instead of a raw decode error wrapped as ErrConnect - Connect: TLS config failures surface as ErrInvalidConfig, not ErrConnect - isTLSImplied: use net/url.Parse to inspect only tls/ssl query params case-insensitively — prevents false positives from substring matching (e.g. credentials or unrelated params containing 'tls=true') * test(assert,crypto,mongo): add typed-nil and timeout coverage - assert: add TestIsNil_TypedNilPointer — verifies isNil detects typed-nil pointers stored in interface{} - crypto: add typed-nil logger test exercising the isNilInterface path - mongo integration: bound all contexts with timeouts (60s setup, 30s per test/cleanup) to prevent CI hangs if Docker or Mongo wedges - mongo unit: add normalizeConfig whitespace trimming tests, isTLSImplied false-positive and case-insensitivity tests, ErrInvalidConfig assertion for invalid base64 CA cert * chore: rename Makefile help banner from Lib-Uncommons to Lib-Commons * fix(mongo): preserve error chain in SanitizedError with Unwrap Add cause field and Unwrap() method to SanitizedError so callers can still use errors.Is/As to match context.Canceled, context.DeadlineExceeded, or driver sentinels through the credential-sanitization layer. X-Lerian-Ref: 0x1 * fix(circuitbreaker): consolidate duplicate state change logging Remove the generic WARN log and fold the from-state into each specific state-case log entry. Each transition now produces a single structured log instead of two. X-Lerian-Ref: 0x1 * docs(assert): correct UUID doc example and add parallelism annotations Fix misleading NotNil on uuid.UUID value type (use NotEmpty on String()) in doc.go. Add 'Not parallel' comments to four shouldIncludeStack tests that use t.Setenv. X-Lerian-Ref: 0x1 * fix(build): harden Makefile for portability and correctness Five fixes from CodeRabbit review: - clean target: use $(TEST_REPORTS_DIR) instead of hardcoded ./reports - test-integration/coverage-integration: replace xargs dirname with find -exec (set -e safety) - setup-git-hooks/check-hooks: resolve hooks dir via git rev-parse (worktree/submodule compat) - check-envs: exclude .example/.sample/.template files and tighten secret regex to skip comments X-Lerian-Ref: 0x1 * feat(mongo): Allow using system TLS CAs when no custom CA is given The TLS configuration is updated to allow connections without specifying a custom CA certificate. If CACertBase64 is empty, the client now defaults to using the host system's root CA pool. This simplifies connecting to standard cloud providers like MongoDB Atlas, which use widely trusted CAs, removing the need to manually manage and provide the CA certificate in the configuration. Additionally, the client is made non-reusable after being closed. Calling Close() now marks the client as terminally closed, causing subsequent calls to Connect() or ResolveClient() to fail immediately with ErrClientClosed. This ensures a more predictable and robust client lifecycle. --- .githooks/commit-msg/commit-msg | 52 - .githooks/pre-commit/pre-commit | 56 - .githooks/pre-push/pre-push | 17 -

Removed `NewMultiTenantConsumer`** + +| v3 | v4 | +|---|---| +| `consumer.NewMultiTenantConsumer(cfg, logger) *MultiTenantConsumer` | removed; use `consumer.NewMultiTenantConsumerWithError(cfg, logger) (*MultiTenantConsumer, error)` | + +The deprecated panicking constructor has been removed. `NewMultiTenantConsumerWithError` returns an error on invalid configuration instead of calling `panic()`. + +**2. 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;

-The following common sensitive field names are automatically obfuscated (case-insensitive): - -### Authentication & Security -- `password` -- `token` -- `secret` -- `key` -- `authorization` -- `auth` -- `credential` -- `credentials` -- `apikey` -- `api_key` -- `access_token` -- `refresh_token` -- `private_key` -- `privatekey` - -> **Note**: This list is shared with HTTP logging middleware and other components via `security.DefaultSensitiveFields` to ensure consistent behavior across the entire commons library. - -## API Reference - -### Core Functions - -#### `SetSpanAttributesFromStruct(span *trace.Span, key string, valueStruct any) error` -Original function for backward compatibility. Adds struct data to span without obfuscation. - -#### `SetSpanAttributesFromStructWithObfuscation(span *trace.Span, key string, valueStruct any, obfuscator FieldObfuscator) error` -Enhanced function that applies obfuscation before adding struct data to span. If `obfuscator` is `nil`, behaves like the original function. +If you still want global providers, call it explicitly: -#### `ObfuscateStruct(valueStruct any, obfuscator FieldObfuscator) (any, error)` -Standalone utility function that obfuscates a struct and returns the result. Can be used independently of OpenTelemetry spans. - -### Obfuscator Constructors - -#### `NewDefaultObfuscator() *DefaultObfuscator` -Creates an obfuscator with predefined common sensitive field names. - -#### `NewCustomObfuscator(sensitiveFields []string) *CustomObfuscator` -Creates an obfuscator with custom sensitive field names. Field matching is case-insensitive and uses exact matching (not word-boundary matching like `DefaultObfuscator`). - -### Interface - -#### `FieldObfuscator` ```go -type FieldObfuscator interface { - // ShouldObfuscate returns true if the given field name should be obfuscated - ShouldObfuscate(fieldName string) bool - // GetObfuscatedValue returns the value to use for obfuscated fields - GetObfuscatedValue() string -} +tl.ApplyGlobals() ``` -### Constants - -#### `ObfuscatedValue = "***"` -Default value used to replace sensitive fields. Can be referenced for consistency. - -## Advanced Features +## Span attributes from objects -### Recursive Obfuscation -The obfuscation system works recursively on: -- **Nested structs**: Processes all nested object fields -- **Arrays and slices**: Processes each element in collections -- **Maps**: Processes all key-value pairs - -### Case-Insensitive Matching -Field name matching is case-insensitive for flexibility: ```go -// All these variations will be obfuscated if "password" is in the sensitive list -"password", "Password", "PASSWORD", "PaSsWoRd" +err := opentelemetry.SetSpanAttributesFromValue(span, "request", payload, opentelemetry.NewDefaultRedactor()) ``` -### Performance Considerations -- **Efficient processing**: Uses pre-allocated maps for field lookups -- **Memory conscious**: Minimal allocations during recursive processing -- **JSON conversion**: Leverages Go's efficient JSON marshaling/unmarshaling - -## Best Practices +This flattens nested values into typed attributes (`request.user.id`, `request.amount`, etc.). -### Security -- **Always use obfuscation** for production telemetry data -- **Review sensitive field lists** regularly to ensure comprehensive coverage -- **Implement custom obfuscators** for business-specific sensitive data -- **Test obfuscation rules** to verify sensitive data is properly hidden - -### Performance -- **Reuse obfuscator instances** instead of creating new ones for each call -- **Use appropriate obfuscation level** - don't over-obfuscate if not needed -- **Consider caching** obfuscated results for frequently used structs - -### Maintainability -- **Use `NewDefaultObfuscator()`** for most common use cases -- **Document custom obfuscation rules** in your business logic -- **Centralize obfuscation policies** for consistency across services -- **Test obfuscation behavior** in your unit tests - -### Migration -- **Backward compatibility**: Existing code using `SetSpanAttributesFromStruct()` continues to work -- **Gradual adoption**: Add obfuscation incrementally to existing telemetry code -- **Monitoring**: Verify obfuscated telemetry data meets security requirements - -## Error Handling - -The obfuscation functions return errors in these cases: -- **Invalid JSON**: When the input struct cannot be marshaled to JSON -- **Malformed data**: When JSON unmarshaling fails during processing +## Redaction ```go -err := opentelemetry.SetSpanAttributesFromStructWithObfuscation( - &span, "data", invalidStruct, obfuscator) -if err != nil { - log.Printf("Obfuscation failed: %v", err) - // Handle error appropriately -} +redactor, err := opentelemetry.NewRedactor([]opentelemetry.RedactionRule{ + {FieldPattern: `(?i)^password$`, Action: opentelemetry.RedactionMask}, + {FieldPattern: `(?i)^document$`, Action: opentelemetry.RedactionHash}, + {PathPattern: `(?i)^session\.token$`, FieldPattern: `(?i)^token$`, Action: opentelemetry.RedactionDrop}, +}, "***") ``` -## Testing +Available actions: -The package includes comprehensive tests covering: -- **Default obfuscator behavior** -- **Custom obfuscator functionality** -- **Recursive obfuscation of nested structures** -- **Error handling for invalid data** -- **Integration with OpenTelemetry spans** -- **Custom obfuscator interface implementations** - -Run tests with: -```bash -go test ./commons/opentelemetry -v -``` +- `RedactionMask` +- `RedactionHash` +- `RedactionDrop` -## Examples +## Propagation -For complete working examples, see: -- `obfuscation_test.go` - Comprehensive test cases -- `examples/opentelemetry_obfuscation_example.go` - Runnable example application +Use carrier-first APIs: -## Contributing +- `InjectTraceContext(ctx, carrier)` +- `ExtractTraceContext(ctx, carrier)` -When adding new features: -1. **Follow the interface pattern** for extensibility -2. **Add comprehensive tests** for new functionality -3. **Update documentation** with examples -4. **Maintain backward compatibility** with existing APIs -5. **Follow Go best practices** and the project's coding standards +Transport adapters remain available for HTTP/gRPC/queue integration. diff --git a/commons/opentelemetry/doc.go b/commons/opentelemetry/doc.go new file mode 100644 index 00000000..63ebcb6c --- /dev/null +++ b/commons/opentelemetry/doc.go @@ -0,0 +1,8 @@ +// Package opentelemetry provides tracing, metrics, propagation, and redaction helpers. +// +// NewTelemetry builds providers/exporters and can run in disabled mode for local/dev +// environments while preserving API compatibility. +// +// The package also includes carrier utilities for HTTP, gRPC, and queue headers, plus +// redaction-aware attribute extraction for safe span enrichment. +package opentelemetry diff --git a/commons/opentelemetry/extract_queue_test.go b/commons/opentelemetry/extract_queue_test.go deleted file mode 100644 index 13f9dd1e..00000000 --- a/commons/opentelemetry/extract_queue_test.go +++ /dev/null @@ -1,147 +0,0 @@ -// Copyright (c) 2026 Lerian Studio.

have one clear purpose +2. **Minimal Dependencies**: Packages should minimize external dependencies +3. **Interface-Driven**: Define interfaces for testability and flexibility +4. **Zero Business Logic**: This is a utility library - no domain/business logic +5. **Nil-Safe and Concurrency-Safe**: Keep behavior safe by default +6. **Explicit Error Returns**: Prefer error returns over panic paths + +### Naming Conventions + +| Type | Convention | Example | +|------|------------|---------| +| Package | lowercase, single word preferred | `postgres`, `redis`, `circuitbreaker` | +| Files | snake_case or camelCase matching content | `pool_manager_pg.go`, `stringUtils.go` | +| Public Functions | PascalCase, descriptive | `NewClient`, `ServeReverseProxy` | +| Private Functions | camelCase | `validateConfig` | +| Interfaces | -er suffix or descriptive | `Logger`, `Manager`, `LockManager` | +| Constants | PascalCase | `DefaultTimeout`, `LevelInfo` | + +--- + +## Code Conventions + +### Go Version + +- **Minimum**: Go 1.25.7 +- Keep `go.mod` updated with latest stable Go version +- Module path: `github.com/LerianStudio/lib-commons/v4` + +### Build Tags + +- Unit test files **MUST** have `//go:build unit` as the first line +- Integration test files **MUST** have `//go:build integration` as the first line + +```go +//go:build unit + +package mypackage + +import "testing" + +func TestMyFunc(t *testing.T) { ... } +``` + +### Imports Organization + +```go +import ( + // Standard library + "context" + "fmt" + "time" + + // Third-party packages + "github.com/jackc/pgx/v5" + "go.uber.org/zap" + + // Internal packages + "github.com/LerianStudio/lib-commons/v4/commons/log" +) +``` + +### Function Design + +1. **Context First**: Functions that may block should accept `context.Context` as first parameter +2. **Options Pattern**: Use functional options for configurable constructors +3. **Error Last**: Return errors as the last return value +4. **Named Returns**: Avoid named returns except for documentation + +```go +// Good +func NewClient(ctx context.Context, opts ...Option) (*Client, error) + +// Avoid +func NewClient(opts ...Option) (client *Client, err error) +``` + +### Struct Design + +```go +type Config struct { + Host string `json:"host"` + Port int `json:"port"` + Timeout time.Duration `json:"timeout"` + MaxConns int `json:"max_conns"` +} + +func (c *Config) Validate() error { + if c.Host == "" { + return ErrEmptyHost + } + return nil +} +``` + +### Constants and Variables + +```go +const ( + DefaultTimeout = 30 * time.Second + DefaultMaxConns = 10 +) + +var ( + ErrNotFound = errors.New("not found") + ErrInvalidInput = errors.New("invalid input") +) +``` + +--- + +## Error Handling + +### Error Definition + +1. **Sentinel Errors**: Define package-level errors for expected conditions +2. **Error Wrapping**: Use `fmt.Errorf` with `%w` for context +3. **Custom Types**: Use custom error types when additional context is needed + +```go +var ( + ErrConnectionFailed = errors.New("connection failed") + ErrTenantNotFound = errors.New("tenant not found") +) + +// Wrapping +return fmt.Errorf("failed to connect to %s: %w", host, err) + +// Custom type +type ValidationError struct { + Field string + Message string +} + +func (e *ValidationError) Error() string { + return fmt.Sprintf("validation failed for %s: %s", e.Field, e.Message) +} +``` + +### Error Handling Rules + +1. **NEVER use panic()** - Always return errors +2. **NEVER ignore errors** - Handle or propagate all errors +3. **Log at boundaries** - Log errors at service boundaries, not in library code +4. **Provide context** - Wrap errors with meaningful context + +```go +// Good +if err != nil { + return fmt.Errorf("failed to execute query: %w", err) +} + +// Bad - panics +if err != nil { + panic(err) +} + +// Bad - ignores error +result, _ := doSomething() +``` + +--- + +## Testing Requirements + +### Coverage Requirements + +- **Minimum Coverage**: 80% for new packages +- **Critical Paths**: 100% coverage for error handling paths +- **Run Coverage**: `make coverage-unit` or `make coverage-integration` +- **Coverage Exclusions**: Defined in `.ignorecoverunit` (e.g., `*_mock.go`) + +### Build Tags + +All test files **MUST** include the appropriate build tag as the first line: + +| Type | Build Tag | Example | +|------|-----------|---------| +| Unit Tests | `//go:build unit` | All `_test.go` files | +| Integration Tests | `//go:build integration` | All `_integration_test.go` files | + +### Test File Naming + +| Type | Pattern | Example | +|------|---------|---------| +| Unit Tests | `{file}_test.go` | `config_test.go` | +| Integration | `{file}_integration_test.go` | `postgres_integration_test.go` | +| Examples | `{feature}_example_test.go` | `cursor_example_test.go` | +| Benchmarks | In `_test.go` or `benchmark_test.go` | `BenchmarkXxx` | + +### Integration Test Conventions + +- Test function names **MUST** start with `TestIntegration_` (e.g., `TestIntegration_MyFeature_Works`) +- Integration tests use `testcontainers-go` to spin up ephemeral containers +- Docker is required to run integration tests +- Integration tests run sequentially (`-p=1`) to avoid Docker container conflicts + +### Test Patterns + +```go +func TestConfig_Validate(t *testing.T) { + tests := []struct { + name string + config Config + wantErr bool + }{ + { + name: "valid config", + config: Config{Host: "localhost", Port: 5432}, + wantErr: false, + }, + { + name: "empty host", + config: Config{Host: "", Port: 5432}, + wantErr: true, + }, + } + + for _, tt := range tests { + t.Run(tt.name, func(t *testing.T) { + err := tt.config.Validate() + if (err != nil) != tt.wantErr { + t.Errorf("Validate() error = %v, wantErr %v", err, tt.wantErr) + } + }) + } +} +``` + +### Test Data + +- Use realistic but fake data (e.g., `"pass"`, `"secret"` for passwords in tests) +- Never use real credentials in tests +- Use test fixtures for complex data structures + +### Mocking + +- Use `go.uber.org/mock` for interface mocking +- Define interfaces at point of use for testability +- Prefer dependency injection over global state +- Mock files follow the `{type}_mock.go` pattern + +--- + +## Documentation Standards + +### Package Documentation + +Every package MUST have a `doc.go` file or package comment: + +```go +// Package postgres provides PostgreSQL connection management utilities. +// +// It supports connection pooling, migrations, and read-replica configurations +// for high-availability deployments. +package postgres +``` + +### Function Documentation + +Public functions MUST have documentation: + +```go +// Connect establishes a connection to the PostgreSQL database. +// It validates the configuration before attempting to connect. +// +// Returns an error if the configuration is invalid or connection fails. +func (c *Client) Connect(ctx context.Context) error { +``` + +### README Updates + +- Update `README.md` API Reference when adding public APIs +- Include usage examples for new packages + +### Migration Awareness + +- If a task touches renamed/removed v1 symbols, update `MIGRATION_MAP.md` +- If a task changes package-level behavior or API expectations, update `README.md` + +--- + +## Dependencies + +### Allowed Dependencies + +| Category | Allowed Packages | +|----------|-----------------| +| Database | `pgx/v5`, `mongo-driver`, `go-redis/v9`, `dbresolver/v2`, `golang-migrate/v4` | +| Messaging | `amqp091-go` | +| HTTP | `gofiber/fiber/v2` | +| Logging |

(use internal `log` wrapper) + +### Adding Dependencies + +1. Check if functionality exists in standard library +2. Check if existing dependency provides the functionality +3. Evaluate package maintenance and security +4. Add to `go.mod` with specific version + +--- + +## Security + +### Credential Handling + +1. **Never hardcode credentials** - Use environment variables +2. **Never log credentials** - Use the `Redactor` for sensitive fields +3. **Mask in errors** - Never include credentials in error messages + +```go +// Use the built-in Redactor for sensitive data +redactor := opentelemetry.NewDefaultRedactor() +safeValue := redactor.Redact(sensitiveField) +``` + +### Sensitive Field Detection + +- Use `commons/security` for sensitive field detection and handling +- Use `commons/opentelemetry.Redactor` with `RedactionRule` patterns +- Constructors: `NewDefaultRedactor()` and `NewRedactor(rules, mask)` + +### Input Validation + +1. Validate all external inputs +2. Use parameterized queries - never string concatenation +3. Sanitize user-provided identifiers +4. Use `go-playground/validator/v10` for struct validation + +### Log Injection Prevention + +- Use `commons/log/sanitizer.go` for log-injection prevention +- Never interpolate untrusted input into log messages without sanitization + +### Environment Variables + +- Use `SECURE_LOG_FIELDS` for field obfuscation +- Document required environment variables +- Provide sensible defaults where safe + +---

It relies on an external call to EnsureConsumerStarted() that no consumer service (e.g., reporter-worker) makes. Result: tenants are discovered but zero consumers are spawned, and no messages are consumed. Fix: Add EagerStart config option (default: true). When enabled, Run() bootstraps consumers for all discovered tenants at startup, and syncTenants() auto-starts consumers for newly discovered tenants during the sync loop. Lazy mode (EagerStart=false) is preserved for backward compatibility. Problem 2: Run() receives a context that may not have a logger attached (e.g., context.Background()). NewTrackingFromContext returns a noop logger, silencing all internal logs from discovery, sync, and consumer management.

90b01349d357717b67ab8dd60fb34487c223a247 Mon Sep 17 00:00:00 2001 From: Fred Amaral Date: Sat, 14 Mar 2026 09:07:53 -0300 Subject: [PATCH 076/118] refactor(http/proxy): extract SSRF transport and validation into dedicated files Move SSRF-safe transport dial logic to proxy_transport.go and target validation helpers to proxy_validation.go. Add nil-safe header init and nilcheck.Interface guards. Relocate tests to focused files covering defensive, forwarding, SSRF, and transport scenarios.

17 00:00:00 2001 From: Fred Amaral Date: Sat, 14 Mar 2026 09:07:58 -0300 Subject: [PATCH 077/118] refactor(http/withLogging): extract middleware, obfuscation, and sanitization into dedicated files Move HTTP/gRPC logging middleware to withLogging_middleware.go, body obfuscation helpers to withLogging_obfuscation.go, and referer/log-value sanitization (CWE-117 hardening) to withLogging_sanitize.go. Add gRPC-specific test coverage.

strings.Cut for URL sanitization Replaces the usage of `strings.IndexByte` with the more idiomatic Go function `strings.Cut`. This function is specifically designed to split a string into two parts based on a separator, making the code for redacting URL query parameters clearer and more expressive. fix(test): remove parallel execution to fix flaky telemetry tests The telemetry tests in `withTelemetry_test.go` modify shared global state related to the metrics collector. Running them with `t.Parallel()` created a race condition, leading to intermittent test failures. Removing `t.Parallel()` forces these tests to run sequentially, eliminating the race condition and stabilizing the test suite. A short sleep was also added to the reset function to ensure the collector has sufficient time to shut down before the next test starts. style(test): align struct field values in multi tenant test Adjusts code formatting in `multi_tenant_test.go` for better readability by aligning the values in a struct literal. This is a purely cosmetic change with no functional impact. --- commons/net/http/withTelemetry_helpers.go | 4 ++-- commons/net/http/withTelemetry_test.go | 4 +--- commons/tenant-manager/consumer/multi_tenant_test.go | 4 ++-- 3 files changed, 5 insertions(+), 7 deletions(-) diff --git a/commons/net/http/withTelemetry_helpers.go b/commons/net/http/withTelemetry_helpers.go index 6113e3c8..d7751f6c 100644 --- a/commons/net/http/withTelemetry_helpers.go +++ b/commons/net/http/withTelemetry_helpers.go @@ -58,8 +58,8 @@ func sanitizeURL(rawURL string) string { func sanitizeMalformedURL(rawURL string) string { sanitized := sanitizeLogValue(rawURL) - if idx := strings.IndexByte(sanitized, '?'); idx >= 0 { - return sanitized[:idx] + "?redacted" + if before, _, ok := strings.Cut(sanitized, "?"); ok { + return before + "?redacted" } return sanitized diff --git a/commons/net/http/withTelemetry_test.go b/commons/net/http/withTelemetry_test.go index daebceb5..b3b31b40 100644 --- a/commons/net/http/withTelemetry_test.go +++ b/commons/net/http/withTelemetry_test.go @@ -550,6 +550,7 @@ func resetMetricsCollectorState() { if metricsCollectorStarted && metricsCollectorShutdown != nil { close(metricsCollectorShutdown) + time.Sleep(50 * time.Millisecond) } metricsCollectorShutdown = nil @@ -559,7 +560,6 @@ func resetMetricsCollectorState() { } func TestEnsureMetricsCollector_ReturnsErrorWhenMetricsFactoryNil(t *testing.T) { - t.Parallel() resetMetricsCollectorState() t.Cleanup(resetMetricsCollectorState) @@ -575,7 +575,6 @@ func TestEnsureMetricsCollector_ReturnsErrorWhenMetricsFactoryNil(t *testing.T) } func TestEnsureMetricsCollector_NoMeterProviderReturnsNil(t *testing.T) { - t.Parallel() resetMetricsCollectorState() t.Cleanup(resetMetricsCollectorState) @@ -585,7 +584,6 @@ func TestEnsureMetricsCollector_NoMeterProviderReturnsNil(t *testing.T) { } func TestStopMetricsCollector_AllowsRestart(t *testing.T) { - t.Parallel() resetMetricsCollectorState() t.Cleanup(resetMetricsCollectorState) diff --git a/commons/tenant-manager/consumer/multi_tenant_test.go b/commons/tenant-manager/consumer/multi_tenant_test.go index dba21ea0..7968eff0 100644 --- a/commons/tenant-manager/consumer/multi_tenant_test.go +++ b/commons/tenant-manager/consumer/multi_tenant_test.go @@ -889,8 +889,8 @@ func TestMultiTenantConsumer_NewWithZeroConfig(t *testing.T) { { name: "creates_pmClient_when_URL_configured", config: MultiTenantConfig{ - MultiTenantURL: "https://tenant-manager:4003", - ServiceAPIKey: "test-key", + MultiTenantURL: "https://tenant-manager:4003", + ServiceAPIKey: "test-key", }, expectedSync: 30 * time.Second, expectedWorkers: 0, // WorkersPerQueue is deprecated, default is 0 From 27ee9f31faa0ee482631defd658a782b5a155934 Mon Sep 17 00:00:00 2001 From: Gandalf Date: Tue, 17 Mar 2026 01:59:47 -0300 Subject: [PATCH 085/118] refactor(client): rename /settings endpoint to /connections MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Align lib-commons tenant-manager client with tenant-manager API rename (LerianStudio/tenant-manager#109).

Add AllowInsecureHTTP bool field to MultiTenantConfig. When true, the constructor passes client.WithAllowInsecureHTTP() to client.NewClient. Default false preserves backward compatibility.

Previously, devs had to pass tenant_id manually on every log call. This adds TenantAwareLogger, a thin wrapper that extracts tenant_id from context and injects it automatically. Integrated in logcompat.New() so consumer, MongoDB, and RabbitMQ managers get it for free. Zero behavior change when tenant_id is not in context.

IdentityFromHeader and IdentityFromIPAndHeader now URL-encode each component and prefix with type tags (hdr:/ip:) so header values that look like IPs, IPv6 colons, and '#' characters cannot produce colliding Redis keys. Format: IdentityFromHeader → hdr: or ip: IdentityFromIPAndHeader → ip::hdr: or ip: 2. WithRateLimit and WithDynamicRateLimit now reject tiers whose Window <= 0 or whose Window.Milliseconds() == 0 (sub-millisecond). Such windows cause PEXPIRE 0, silently expiring every key and bypassing the rate limit entirely. The handlers return 503 misconfigured_rate_limiter instead of calling check. 3. RATE_LIMIT_REDIS_TIMEOUT_MS env var is clamped to fallbackRedisTimeoutMS when non-positive, preventing an immediately-expired context.WithTimeout that would make every Redis call fail at startup. 4. TestNew_RateLimitEnabledEnv now always calls t.Setenv regardless of whether tt.envVal is empty, making the empty-string case deterministic under any inherited environment.
