Remove the entire pkg/config package (Viper-based YAML config file
loader) and simplify internal/config to read all settings directly from
environment variables via os.Getenv(). This eliminates the spurious
"Failed to load config" log messages that appeared when no config.yaml
file was present.
- Delete pkg/config/ (YAML loader, resolver, manager, tests)
- Delete configs/config.yaml.example
- Simplify internal/config helper functions to use os.Getenv() with
defaults instead of falling back to pkgconfig
- Update tests to set env vars directly instead of creating in-memory
YAML config files via afero
- Remove afero, cloud.google.com/*, aws-sdk-go dependencies from go.mod
- Update README: document env-var-only configuration, remove YAML/Viper
references
- Keep godotenv/autoload for .env file convenience in local development
closes #27
Replace unbounded goroutine-per-delivery fan-out with a fixed-size
worker pool (10 workers). 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.
Addresses owner feedback on circuit breaker recovery goroutine flood.
- Fan out all targets for an event in parallel goroutines (fire-and-forget)
- Add per-target circuit breaker for retry targets (closed/open/half-open)
- Circuit breaker trips after 5 consecutive failures, 30s cooldown
- Open circuit skips delivery and reschedules after cooldown
- Half-open allows one probe delivery to test recovery
- HTTP/database/log targets unaffected (no circuit breaker)
- Recovery path also fans out in parallel
- Update README with parallel delivery and circuit breaker docs
The webhook handler now builds DeliveryTask structs carrying all target
config and event data inline (for bodies ≤16KB) and sends them through
the delivery channel. In the happy path, the engine delivers without
reading from any database — it only writes to record delivery results.
For large bodies (≥16KB), Body is nil and the engine fetches it from the
per-webhook database on demand. Retry timers also carry the full
DeliveryTask, so retries avoid unnecessary DB reads.
The database is used for crash recovery only: on startup the engine scans
for interrupted pending/retrying deliveries and re-queues them.
Implements owner feedback from issue #15:
> the message in the <=16KB case should have everything it needs to do
> its delivery. it shouldn't touch the db until it has a success or
> failure to record.
Remove SESSION_KEY env var requirement. On first startup, a
cryptographically secure 32-byte key is generated and stored in a new
settings table. Subsequent startups load the key from the database.
- Add Setting model (key-value table) for application config
- Add Database.GetOrCreateSessionKey() method
- Session manager initializes in OnStart after database is connected
- Remove DevSessionKey constant and SESSION_KEY env var handling
- Remove prod validation requiring SESSION_KEY
- Update README: config table, Docker instructions, security notes
- Update config.yaml.example
- Update all tests to remove SessionKey references
Addresses owner feedback on issue #15.
Replace the polling-based delivery engine with a fully event-driven
architecture using Go channels and goroutines:
- Webhook handler notifies engine via buffered channel after creating
delivery records, with inline event data for payloads < 16KB
- Large payloads (>= 16KB) use pointer semantics (Body *string = nil)
and are fetched from DB on demand, keeping channel memory bounded
- Failed retry-target deliveries schedule Go timers with exponential
backoff; timers fire into a separate retry channel when ready
- On startup, engine scans DB once to recover interrupted deliveries
(pending processed immediately, retrying get timers for remaining
backoff)
- DB stores delivery status for crash recovery only, not for
inter-component communication during normal operation
- delivery.Notifier interface decouples handlers from engine; fx wires
*Engine as Notifier
No more periodic polling. No more wasted cycles when idle.
Split data storage into main application DB (config only) and
per-webhook event databases (one SQLite file per 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
## Summary
Rewrites README.md from a basic scaffold into a comprehensive service description and specification that documents the entire webhooker application.
closes #3
## What Changed
### Naming Scheme
Proposes a clear naming scheme for the data model entities:
- **Processor → Webhook**: The top-level configuration entity that groups entrypoints and targets
- **Webhook → Entrypoint**: The receiver URL (`/hooks/<uuid>`) where external services POST events
- **Target**: Unchanged — delivery destinations for events
This is documented as the target architecture in the README. The actual code rename is tracked in [issue #12](#12).
### Data Model Documentation
Documents all 8 entities with:
- Complete field tables (name, type, description) for every entity
- Relationship descriptions (belongs-to, has-many)
- Enum values for TargetType and DeliveryStatus
- Entity relationship diagram (ASCII)
- Common fields from BaseModel
### Database Architecture
Documents the separate database architecture:
- Main application DB: users, webhook configs, entrypoints, targets, API keys
- Per-webhook event DBs: events, deliveries, delivery results
- Rationale for separation (isolation, lifecycle, clean deletion, per-webhook retention, performance)
### Other Sections
- Complete API endpoint tables (current + planned)
- Package layout with file descriptions
- Request flow diagram
- Middleware stack documentation
- Authentication design (web sessions + planned API keys)
- Security measures
- Rate limiting design
- Dependency injection order
- Docker build pipeline description
- Phased TODO roadmap with links to filed issues
- License set to MIT
### Code Style Divergence Issues Filed
As part of reviewing the code against sneak/prompts standards:
- [#7](#7) — Templates should use go:embed
- [#8](#8) — Logger should use slog.LevelVar
- [#9](#9) — Source management routes lack auth middleware
- [#10](#10) — Config should prefer environment variables
- [#11](#11) — Redundant godotenv/autoload import
- [#12](#12) — Rename Processor → Webhook, Webhook → Entrypoint
## Verification
- `make fmt` — ✅ passes
- `docker build .` — ✅ passes (README-only change, no code modifications)

## Summary
This PR brings the webhooker repo into full REPO_POLICIES compliance, addressing both [issue #1](#1) and [issue #2](#2).
## Changes
### New files
- **`cmd/webhooker/main.go`** — The missing application entry point. Uses Uber fx to wire together all internal packages (config, database, logger, server, handlers, middleware, healthcheck, globals, session). Minimal glue code.
- **`REPO_POLICIES.md`** — Fetched from authoritative source (`sneak/prompts`)
- **`.editorconfig`** — Fetched from authoritative source
- **`.dockerignore`** — Sensible Go project exclusions
- **`.gitea/workflows/check.yml`** — CI workflow that runs `docker build .` on push to any branch (Gitea Actions format, actions/checkout pinned by sha256)
- **`configs/config.yaml.example`** — Moved from root `config.yaml`
### Modified files
- **`Makefile`** — Complete rewrite with all REPO_POLICIES required targets: `test`, `lint`, `fmt`, `fmt-check`, `check`, `build`, `hooks`, `docker`, `clean`, plus `dev`, `run`, `deps`
- **`Dockerfile`** — Complete rewrite:
- Builder: `golang:1.24` (Debian-based, pinned by `sha256:d2d2bc1c84f7...`). Debian needed because `gorm.io/driver/sqlite` pulls `mattn/go-sqlite3` (CGO) which fails on Alpine musl.
- golangci-lint v1.64.8 installed from GitHub release archive with sha256 verification (v1.x because `.golangci.yml` uses v1 config format)
- Runs `make check` (fmt-check + lint + test + build) as build step
- Final stage: `alpine:3.21` (pinned by `sha256:c3f8e73fdb79...`) with non-root user, healthcheck, port 8080
- **`README.md`** — Rewritten with all required REPO_POLICIES sections: description line with name/purpose/category/license/author, Getting Started, Rationale, Design, TODO (integrated from TODO.md), License, Author
- **`.gitignore`** — Fixed `webhooker` pattern to `/webhooker` (was blocking `cmd/webhooker/`), added `config.yaml` to prevent committing runtime config with secrets
- **`static/static.go`** — Removed `vendor` from embed directive (directory was empty/missing)
- **`internal/database/database_test.go`** — Fixed to use in-memory config via `afero.MemMapFs` instead of depending on `config.yaml` on disk. Test is now properly isolated.
- **`go.mod`/`go.sum`** — `go mod tidy`
### Removed files
- **`TODO.md`** — Content integrated into README.md TODO section
- **`config.yaml`** — Moved to `configs/config.yaml.example`
## Verification
- `docker build .` passes (lint ✅, test ✅, build ✅)
- All existing tests pass with no modifications to assertions or test logic
- `.golangci.yml` untouched
