From 7bbe47b9438a006ff744d1da5b0b4bbcace9fc60 Mon Sep 17 00:00:00 2001 From: clawbot Date: Sun, 1 Mar 2026 15:44:22 -0800 Subject: [PATCH 01/33] refactor: rename Processor to Webhook and Webhook to Entrypoint The top-level entity that groups entrypoints and targets is now called Webhook (was Processor). The inbound URL endpoint entity is now called Entrypoint (was Webhook).

Architecture changes: - New WebhookDBManager component manages per-webhook DB lifecycle (create, open, cache, delete) with lazy connection pooling via sync.Map - Main DB (DBURL) stores only config: Users, Webhooks, Entrypoints, Targets, APIKeys - Per-webhook DBs (DATA_DIR) store Events, Deliveries, DeliveryResults in files named events-{webhook_uuid}.db - New DATA_DIR env var (default: ./data dev, /data/events prod) Behavioral changes: - Webhook creation creates per-webhook DB file - Webhook deletion hard-deletes per-webhook DB file (config soft-deleted) - Event ingestion writes to per-webhook DB, not main DB - Delivery engine polls all per-webhook DBs for pending deliveries - Database target type marks delivery as immediately successful (events are already in the dedicated per-webhook DB) - Event log UI reads from per-webhook DBs with targets from main DB - Existing webhooks without DB files get them created lazily Removed: - ArchivedEvent model (was a half-measure, replaced by per-webhook DBs) - Event/Delivery/DeliveryResult removed from main DB migrations Added: - Comprehensive tests for WebhookDBManager (create, delete, lazy creation, delivery workflow, multiple webhooks, close all) - Dockerfile creates /data/events directory README updates: - Per-webhook event databases documented as implemented (was Phase 2) - DATA_DIR added to configuration table - Docker instructions updated with data volume mount - Data model diagram updated - TODO updated (database separation moved to completed) Closes #15 --- Dockerfile | 5 +- README.md | 113 ++++--- cmd/webhooker/main.go | 1 + internal/config/config.go | 12 + internal/database/model_archived_event.go | 19 -- internal/database/models.go | 9 +- internal/database/webhook_db_manager.go | 183 ++++++++++++ internal/database/webhook_db_manager_test.go | 294 +++++++++++++++++++ internal/delivery/engine.go | 199 ++++++++----- internal/handlers/handlers.go | 13 +- internal/handlers/handlers_test.go | 4 + internal/handlers/source_management.go | 125 +++++--- internal/handlers/webhook.go | 35 ++- 13 files changed, 814 insertions(+), 198 deletions(-) delete mode 100644 internal/database/model_archived_event.go create mode 100644 internal/database/webhook_db_manager.go create mode 100644 internal/database/webhook_db_manager_test.go diff --git a/Dockerfile b/Dockerfile index 9d2022d..a2ce1fe 100644 --- a/Dockerfile +++ b/Dockerfile @@ -57,7 +57,10 @@ WORKDIR /app # Copy binary from builder COPY --from=builder /build/bin/webhooker . -RUN chown -R webhooker:webhooker /app +# Create data directory for per-webhook event databases +RUN mkdir -p /data/events + +RUN chown -R webhooker:webhooker /app /data/events USER webhooker diff --git a/README.md b/README.md index 3ca00aa..235a19f 100644 --- a/README.md +++ b/README.md @@ -66,7 +66,8 @@ Configuration is resolved in this order (highest priority first): | ----------------------- | ----------------------------------- | -------- | | `WEBHOOKER_ENVIRONMENT` | `dev` or `prod` | `dev` | | `PORT` | HTTP listen port | `8080` | -| `DBURL` | SQLite database connection string | *(required)* | +| `DBURL` | SQLite connection string (main app DB) | *(required)* | +| `DATA_DIR` | Directory for per-webhook event DBs | `./data` (dev) / `/data/events` (prod) | | `SESSION_KEY` | Base64-encoded 32-byte session key | *(required in prod)* | | `DEBUG` | Enable debug logging | `false` | | `METRICS_USERNAME` | Basic auth username for `/metrics` | `""` | @@ -84,6 +85,7 @@ docker run -d \ -p 8080:8080 \ -v /path/to/data:/data \ -e DBURL="file:/data/webhooker.db?cache=shared&mode=rwc" \ + -e DATA_DIR="/data/events" \ -e SESSION_KEY="" \ -e WEBHOOKER_ENVIRONMENT=prod \ webhooker:latest @@ -91,7 +93,10 @@ docker run -d \ The container runs as a non-root user (`webhooker`, UID 1000), exposes port 8080, and includes a health check against -`/.well-known/healthcheck`. +`/.well-known/healthcheck`.

Channels serve as bounded queues (10,000 buffer). Workers are the only goroutines doing HTTP delivery. When retry channel overflows, timers are dropped instead of re-armed. The delivery stays in 'retrying' status in the DB and a periodic sweep (every 60s) recovers orphaned retries. The database is the durable fallback — same path used on startup recovery.

Use environment variables: - ```yaml - secrets: - api_key: $ENV:LOCAL_API_KEY - ``` - -2. Use local files: - ```yaml - secrets: - api_key: $FILE:~/.secrets/api-key.txt - ``` - -3. Create a `config.local.yaml` (gitignored) with literal values for testing - -## Cloud Provider Support - -### Google Secret Manager - -To use GSM resolution (`$GSM:` prefix): -1. Set `GCPProject` in your config -2. Ensure proper authentication (e.g., `GOOGLE_APPLICATION_CREDENTIALS` environment variable) -3. The module will automatically initialize the GSM client when needed - -### AWS Secrets Manager - -To use ASM resolution (`$ASM:` prefix): -1. Optionally set `AWSRegion` in your config (defaults to us-east-1) -2. Ensure proper authentication (e.g., AWS credentials in environment or IAM role) -3. The module will automatically initialize the ASM client when needed - -## Advanced Usage - -### Loading from a Specific File - -```go -// Load configuration from a specific file -if err := config.LoadFile("/path/to/config.yaml"); err != nil { - log.Fatal(err) -} -``` - -### Checking Configuration Values - -```go -// Get all configuration for current environment -allConfig := config.GetAllConfig() -for key, value := range allConfig { - fmt.Printf("%s: %v\n", key, value) -} - -// Get all secrets (be careful with logging!) -allSecrets := config.GetAllSecrets() -``` - -## Testing - -The module uses the [afero](https://github.com/spf13/afero) filesystem abstraction, making it easy to test without real files: - -```go -package myapp_test - -import ( - "testing" - "github.com/spf13/afero" - "git.eeqj.de/sneak/webhooker/pkg/config" -) - -func TestMyApp(t *testing.T) { - // Create an in-memory filesystem for testing - fs := afero.NewMemMapFs() - - // Write a test config file - testConfig := ` -environments: - test: - config: - apiURL: http://test.example.com - secrets: - apiKey: test-key-123 -` - afero.WriteFile(fs, "config.yaml", []byte(testConfig), 0644) - - // Use the test filesystem - config.SetFs(fs) - config.SetEnvironment("test") - - // Now your tests use the in-memory config - if url := config.GetString("apiURL"); url != "http://test.example.com" { - t.Errorf("Expected test URL, got %s", url) - } -} -``` - -### Unit Testing with Isolated Config - -For unit tests, you can create isolated configuration managers: - -```go -func TestMyComponent(t *testing.T) { - // Create a test-specific manager - manager := config.NewManager() - - // Use in-memory filesystem - fs := afero.NewMemMapFs() - afero.WriteFile(fs, "config.yaml", []byte(testConfig), 0644) - manager.SetFs(fs) - - // Test with isolated configuration - manager.SetEnvironment("test") - value := manager.Get("someKey", "default") -} -``` - -## Error Handling - -- If a config file is not found when using the default loader, an error is returned -- If a key is not found, the default value is returned -- If a special value cannot be resolved (e.g., env var not set, file not found), `nil` is returned -- Cloud provider errors are logged but return `nil` to allow graceful degradation - -## Thread Safety - -All operations are thread-safe. The module uses read-write mutexes to ensure safe concurrent access to configuration data. - -## Example Integration - -```go -package main - -import ( - "log" - "os" - "git.eeqj.de/sneak/webhooker/pkg/config" -) - -func main() { - // Read environment from your app-specific env var - environment := os.Getenv("APP_ENV") - if environment == "" { - environment = "dev" - } - - config.SetEnvironment(environment) - - // Now use configuration throughout your app - databaseURL := config.GetString("database_url") - apiKey := config.GetSecretString("api_key") - - log.Printf("Running in %s environment", environment) - log.Printf("Database URL: %s", databaseURL) -} -``` - -## Migration from Python Version - -The Go version maintains API compatibility with the Python version where possible: - -| Python | Go | -|--------|-----| -| `config.get('key')` | `config.Get("key")` or `config.GetString("key")` | -| `config.getSecret('key')` | `config.GetSecret("key")` or `config.GetSecretString("key")` | -| `config.set_environment('prod')` | `config.SetEnvironment("prod")` | -| `config.reload()` | `config.Reload()` | -| `config.get_all_config()` | `config.GetAllConfig()` | -| `config.get_all_secrets()` | `config.GetAllSecrets()` | - -## License - -This module is designed to be standalone and can be extracted into its own repository with your preferred license. \ No newline at end of file diff --git a/pkg/config/config.go b/pkg/config/config.go deleted file mode 100644 index 820c779..0000000 --- a/pkg/config/config.go +++ /dev/null @@ -1,180 +0,0 @@ -// Package config provides a simple, clean, and generic configuration management system -// that supports multiple environments and automatic value resolution. -// -// Features: -// - Simple API: Just config.Get() and config.GetSecret() -// - Environment Support: Separate configs for different environments (dev/prod/staging/etc) -// - Value Resolution: Automatic resolution of special values: -// - $ENV:VARIABLE - Read from environment variable -// - $GSM:secret-name - Read from Google Secret Manager -// - $ASM:secret-name - Read from AWS Secrets Manager -// - $FILE:/path/to/file - Read from file contents -// - Hierarchical Defaults: Environment-specific values override defaults -// - YAML-based: Easy to read and edit configuration files -// - Zero Dependencies: Only depends on yaml and cloud provider SDKs (optional) -// -// Usage: -// -// import "sneak.berlin/go/webhooker/pkg/config" -// -// // Set the environment explicitly -// config.SetEnvironment("prod") -// -// // Get configuration values -// baseURL := config.Get("baseURL") -// apiTimeout := config.GetInt("timeout", 30) -// -// // Get secret values -// apiKey := config.GetSecret("api_key") -// dbPassword := config.GetSecret("db_password", "default") -package config - -import ( - "sync" - - "github.com/spf13/afero" -) - -// Global configuration manager instance -var ( - globalManager *Manager - mu sync.Mutex // Protect global manager updates -) - -// getManager returns the global configuration manager, creating it if necessary -func getManager() *Manager { - mu.Lock() - defer mu.Unlock() - - if globalManager == nil { - globalManager = NewManager() - } - return globalManager -} - -// SetEnvironment sets the active environment. -func SetEnvironment(environment string) { - getManager().SetEnvironment(environment) -} - -// SetFs sets the filesystem to use for all file operations. -// This is primarily useful for testing with an in-memory filesystem. -func SetFs(fs afero.Fs) { - mu.Lock() - defer mu.Unlock() - - // Create a new manager with the specified filesystem - newManager := NewManager() - newManager.SetFs(fs) - - // Replace the global manager - globalManager = newManager -} - -// Get retrieves a configuration value. -// -// This looks for values in the following order: -// 1.

Closed state allows deliveries - Failure counting below threshold - Open transition after threshold failures - Cooldown blocks during cooldown period - Half-open transition after cooldown expires - Probe success closes circuit - Probe failure reopens circuit - Success resets failure counter - Concurrent access safety (race-safe) - CooldownRemaining for all states - CircuitState String() output Engine tests (engine_test.go): - Non-blocking Notify when channel is full - HTTP target success and failure delivery - Database target immediate success - Log target immediate success - Retry target success with circuit breaker - Max retries exhausted marks delivery failed - Retry scheduling on failure - Exponential backoff duration verification - Backoff cap at shift 30 - Body pointer semantics (inline <16KB, nil >=16KB) - Worker pool bounded concurrency - Circuit breaker blocks delivery attempts - Circuit breaker per-target creation - HTTP config parsing (valid, empty, missing URL) - scheduleRetry sends to retry channel - scheduleRetry drops when channel full - Header forwarding (forwardable vs hop-by-hop) - processDelivery routing to correct handler - Truncate helper function All tests use real SQLite databases and httptest servers. All tests pass with -race flag. --- internal/delivery/circuit_breaker_test.go | 243 ++++++ internal/delivery/engine_test.go | 895 ++++++++++++++++++++++ 2 files changed, 1138 insertions(+) create mode 100644 internal/delivery/circuit_breaker_test.go create mode 100644 internal/delivery/engine_test.go diff --git a/internal/delivery/circuit_breaker_test.go b/internal/delivery/circuit_breaker_test.go new file mode 100644 index 0000000..4ea68da --- /dev/null +++ b/internal/delivery/circuit_breaker_test.go @@ -0,0 +1,243 @@ +package delivery + +import ( + "sync" + "testing" + "time" + + "github.com/stretchr/testify/assert" + "github.com/stretchr/testify/require" +) + +func TestCircuitBreaker_ClosedState_AllowsDeliveries(t *testing.T) { + t.Parallel() + cb := NewCircuitBreaker() + + assert.Equal(t, CircuitClosed, cb.State()) + assert.True(t, cb.Allow(), "closed circuit should allow deliveries") + // Multiple calls should all succeed + for i := 0;

2026 23:33:20 -0800 Subject: [PATCH 30/33] chore: consolidate DBURL into DATA_DIR, codebase audit for 1.0.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DBURL → DATA_DIR consolidation: - Remove DBURL env var entirely; main DB now lives at {DATA_DIR}/webhooker.db - database.go constructs DB path from config.DataDir, ensures dir exists - Update DATA_DIR prod default from /data/events to /data - Update all tests to use DataDir instead of DBURL - Update Dockerfile: /data (not /data/events) for all SQLite databases - Update README configuration table, Docker examples, architecture docs Dead code removal: - Remove unused IndexResponse struct (handlers/index.go) - Remove unused TemplateData struct (handlers/handlers.go) Stale comment cleanup: - Remove TODO in server.go (DB cleanup handled by fx lifecycle) - Fix nolint:golint → nolint:revive on ServerParams for consistency - Clean up verbose middleware/routing comments in routes.go - Fix TODO fan-out description (worker pool, not goroutine-per-target) .gitignore fixes: - Add data/ directory to gitignore - Remove stale config.yaml entry (env-only config since rework) --- .gitignore | 4 +--
