13de7cd290 Allow retention_days of 0 to mean retain forever (closes #79)
All checks were successful
check / check (push) Successful in 2m43s
RetentionDays carried gorm:"default:30", so GORM substituted 30 for a
zero value while building the insert. A webhook could therefore never
be configured to keep its events indefinitely: the reaper's
retain-forever branch existed but was unreachable from the normal
create and edit flows.

Introduce database.RetentionForeverDays = 365 * 1000 as the sentinel
for "retain forever" and a Webhook.BeforeSave hook that rewrites any
non-positive RetentionDays to it. The rewrite has to live in the hook
rather than at the call sites: GORM applies the column default while
converting the model to insert values, which happens after BeforeSave,
so anything later loses that race. Putting it on the model also means
a future call site, such as the planned REST API, cannot bypass it.

The reaper now skips a webhook when Webhook.RetainsForever reports
true, which recognises the sentinel and keeps honouring the old <= 0
values for rows written before it existed. Without this the sentinel,
being positive, would have produced a cutoff a thousand years in the
past and a DELETE matching nothing on every sweep.

Bound the finite retention range, which was previously unbounded on
the server. The reaper computes its cutoff as a time.Duration, an
int64 nanosecond count, so a day count above 106751 overflows, wraps
the span negative, and moves the cutoff into the far future — where it
matches every row and the sweep deletes every event, delivery, and
delivery result the webhook has, including ones created seconds ago.
Nothing rejected such a value: parseRetention accepted any v > 0, and
max="365" was a client-side attribute a direct POST ignored, so the
wipe was already reachable on main and removing that attribute would
have made it reachable by ordinary use.

The bound is database.MaxFiniteRetentionDays, derived from the
arithmetic itself as math.MaxInt64 / time.Hour / hoursPerDay rather
than picked as a round number, and a finite value above it is now a
400 that names the ceiling. retentionCutoff additionally clamps the
day count it is given and reports whether any cutoff applies at all,
so a row written by an older version, a migration, or a future call
site cannot reach the overflow either. A value at or above the
retain-forever sentinel stays accepted, because that is what the edit
form pre-fills for a retain-forever webhook.

Form handling is shared by create and edit through parseRetentionDays
so the two cannot drift: an empty field keeps the previous behaviour
(default on create, unchanged on edit), 0 is honoured, and an
unparseable, negative, or out-of-range value is a 400 that re-renders
the form rather than a silently substituted default. The two rejection
reasons are distinct sentinel errors so the message can name the
ceiling, and the create form now carries the submitted name and
description back into the re-rendered inputs, which the edit form
already did.

The retention inputs drop max="365". That cap was not cosmetic: the
edit form pre-fills the stored value, so a retain-forever webhook
rendered 365000 into an input capped at 365 and browser validation
would have blocked saving any edit to it. min becomes 0 with a hint
explaining what 0 does, and the list and detail views render a
RetentionLabel of "forever" instead of a raw day count.

All three Webhook methods take pointer receivers, so there is no
receiver mix and no lint suppression: BeforeSave must take a pointer
to mutate the record, and the handlers hand templates a *Webhook
because html/template cannot call a pointer method on a value held in
a map.

The 30-day default is consolidated into database.DefaultRetentionDays,
referenced from the handler and from the create form's pre-filled
value, with a test asserting it agrees with the struct tag that cannot
reference it.

734606b7af Update golangci-lint to v2.12.2 with canonical config (#86)
All checks were successful
check / check (push) Successful in 3s
Bumps golangci-lint from v2.11.3 to v2.12.2 and adopts the canonical lint config.

## Version pins

- `Dockerfile`: `golangci/golangci-lint:v2.12.2` Debian image, pinned by digest, dated `2026-08-07`
- `script/bootstrap`: `GOLANGCI_LINT_VERSION=2.12.2` with updated sha256 pins for the `linux-amd64` and `linux-arm64` release archives

## Config

`.golangci.yml` replaced with the canonical config. The previous file kept `lll`/`funlen`/`cyclop`/`dupl` settings under the top-level `linters-settings` key, which the v2 schema ignores; the canonical config nests them under `linters.settings`, so those thresholds now actually apply. The unsupported `issues.exclude-use-default` key was dropped.

## Lint fixes (32 findings)

- `lll` (7): wrapped or shortened over-length lines (struct tag comments moved above fields, test logger construction split, `session.NewForTest` signature wrapped, shortened a `#nosec` comment)
- `goconst` (17): replaced repeated `"POST"`/`"PUT"` literals with `http.MethodPost`/`http.MethodPut`, added shared test constants for `webhooker-test`/`test`/`application/json`, and added `tmplKeyError`/`tmplKeyWebhook` constants for template data keys in `internal/handlers`
- `dupl` (8): merged `buildHTTPTargetConfig` and `buildSlackTargetConfig` into a parameterized `buildURLTargetConfig`; removed the duplicate `iWebhookDB` test helper in favor of `testWebhookDB`; extracted shared helpers in middleware and session tests

No `//nolint` directives were added and behavior is unchanged. `make check` (fmt-check, tests, lint) passes.

Note: golangci-lint v2.12 deprecates the `gomodguard` linter in favor of `gomodguard_v2`; the canonical config change for that is left for a future coordinated update.

afe88c601a refactor: use pinned golangci-lint Docker image for linting (#55)
All checks were successful
check / check (push) Successful in 5s
Closes [issue #50](#50)

## Summary

Refactors the Dockerfile to use a separate lint stage with a pinned golangci-lint Docker image, following the pattern used by [sneak/pixa](https://git.eeqj.de/sneak/pixa). This replaces the previous approach of installing golangci-lint via curl in the builder stage.

## Changes

### Dockerfile
- **New `lint` stage** using `golangci/golangci-lint:v2.11.3` (Debian-based, pinned by sha256 digest) as a separate build stage
- **Builder stage** depends on lint via `COPY --from=lint /src/go.sum /dev/null` — build won't proceed unless linting passes
- **Go bumped** from 1.24 to 1.26.1 (`golang:1.26.1-bookworm`, pinned by sha256)
- **golangci-lint bumped** from v1.64.8 to v2.11.3
- All three Docker images (golangci-lint, golang, alpine) pinned by sha256 digest
- Debian-based golangci-lint image used (not Alpine) because mattn/go-sqlite3 CGO does not compile on musl (off64_t)

### Linter Config (.golangci.yml)
- Migrated from v1 to v2 format (`version: "2"` added)
- Removed linters no longer available in v2: `gofmt` (handled by `make fmt-check`), `gosimple` (merged into `staticcheck`), `typecheck` (always-on in v2)
- Same set of linters enabled — no rules weakened

### Code Fixes (all lint issues from v2 upgrade)
- Added package comments to all packages
- Added doc comments to all exported types, functions, and methods
- Fixed unchecked errors flagged by `errcheck` (sqlDB.Close, os.Setenv in tests, resp.Body.Close, fmt.Fprint)
- Fixed unused parameters flagged by `revive` (renamed to `_`)
- Fixed `gosec` G120 warnings: added `http.MaxBytesReader` before `r.ParseForm()` calls
- Fixed `staticcheck` QF1012: replaced `WriteString(fmt.Sprintf(...))` with `fmt.Fprintf`
- Fixed `staticcheck` QF1003: converted if/else chain to tagged switch
- Renamed `DeliveryTask` → `Task` to avoid package stutter (`delivery.Task` instead of `delivery.DeliveryTask`)
- Renamed shadowed builtin `max` parameter to `upperBound` in `cryptoRandInt`
- Used `t.Setenv` instead of `os.Setenv` in tests (auto-restores)

### README.md
- Updated version requirements: Go 1.26+, golangci-lint v2.11+
- Updated Dockerfile description in project structure

## Verification

`docker build .` passes cleanly — formatting check, linting, all tests, and build all succeed.

33e2140a5a feat: redirect root path based on auth state (#52)
All checks were successful
check / check (push) Successful in 1m54s
Closes #51

The root path `/` now checks for an authenticated session and redirects accordingly:

- **Authenticated users** → `303 See Other` redirect to `/sources` (the webhook dashboard)
- **Unauthenticated users** → `303 See Other` redirect to `/pages/login`

### Changes

- **`internal/handlers/index.go`** — Replaced the template-rendering `HandleIndex()` with a session-checking redirect handler. Removed `formatUptime` helper (dead code after this change).
- **`internal/handlers/handlers.go`** — Removed `index.html` from the template map (no longer rendered).
- **`internal/handlers/handlers_test.go`** — Replaced the old "handler is not nil" test with two proper redirect tests:
  - `unauthenticated redirects to login` — verifies 303 to `/pages/login`
  - `authenticated redirects to sources` — sets up an authenticated session cookie, verifies 303 to `/sources`
  - Removed `TestFormatUptime` (tested dead code).
- **`README.md`** — Updated the API endpoints table to describe the new redirect behavior.

### How it works

The handler calls `session.Get(r)` and `session.IsAuthenticated(sess)` — the same pattern used by the `RequireAuth` middleware and `HandleLoginPage`. No new dependencies or session logic introduced.

The login flow is unaffected: `HandleLoginSubmit` redirects to `/` after successful login, which now forwards to `/sources` (one extra redirect hop, but correct and clean).

60786c5019 feat: add CSRF protection, SSRF prevention, and login rate limiting (#42)
All checks were successful
check / check (push) Successful in 4s
## Security Hardening

This PR implements three security hardening issues:

### CSRF Protection (closes #35)

- Session-based CSRF tokens with cryptographically random 256-bit generation
- Constant-time token comparison to prevent timing attacks
- CSRF middleware applied to `/pages`, `/sources`, `/source`, and `/user` routes
- Hidden `csrf_token` field added to all 12+ POST forms in templates
- Excluded from `/webhook` (inbound webhook POSTs) and `/api` (stateless API)

### SSRF Prevention (closes #36)

- `ValidateTargetURL()` blocks private/reserved IP ranges at target creation time
- Blocked ranges: `127.0.0.0/8`, `10.0.0.0/8`, `172.16.0.0/12`, `192.168.0.0/16`, `169.254.0.0/16`, `::1`, `fc00::/7`, `fe80::/10`, plus multicast, reserved, test-net, and CGN ranges
- SSRF-safe HTTP transport with custom `DialContext` in the delivery engine for defense-in-depth (prevents DNS rebinding attacks)
- Only `http` and `https` schemes allowed

### Login Rate Limiting (closes #37)

- Per-IP rate limiter using `golang.org/x/time/rate`
- 5 attempts per minute per IP on `POST /pages/login`
- GET requests (form rendering) pass through unaffected
- Automatic cleanup of stale per-IP limiter entries every 5 minutes
- `X-Forwarded-For` and `X-Real-IP` header support for reverse proxies

### Files Changed

**New files:**
- `internal/middleware/csrf.go` + tests — CSRF middleware
- `internal/middleware/ratelimit.go` + tests — Login rate limiter
- `internal/delivery/ssrf.go` + tests — SSRF validation + safe transport

**Modified files:**
- `internal/server/routes.go` — Wire CSRF and rate limit middleware
- `internal/handlers/handlers.go` — Inject CSRF token into template data
- `internal/handlers/source_management.go` — SSRF validation on target creation
- `internal/delivery/engine.go` — SSRF-safe HTTP transport for production
- All form templates — Added hidden `csrf_token` fields
- `README.md` — Updated Security section and TODO checklist

`docker build .` passes (lint + tests + build).

4dd4dfa5eb chore: consolidate DBURL into DATA_DIR, codebase audit for 1.0.0
All checks were successful
check / check (push) Successful in 56s
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)

5e683af2a4 refactor: event-driven delivery engine with channel notifications and timer-based retries
All checks were successful
check / check (push) Successful in 58s
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.

43c22a9e9a feat: implement per-webhook event databases
All checks were successful
check / check (push) Successful in 1m50s
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

d65480c5ec fix: template rendering returns empty pages (closes #18)
Reorder template.ParseFS arguments so the page template file is listed
first. Go's template package names the template set after the first file
parsed. When htmlheader.html was first, its content (entirely a
{{define}} block) became the root template, which is empty. By putting
the page file first, its {{template "base" .}} invocation becomes the
root action and the page renders correctly.

7f8469a0f2 feat: implement core webhook engine, delivery system, and management UI (Phase 2)
All checks were successful
check / check (push) Successful in 1m49s
- Webhook reception handler: look up entrypoint by UUID, verify active,
  capture full HTTP request (method, headers, body, content-type), create
  Event record, queue Delivery records for each active Target, return 200 OK.
  Handles edge cases: unknown UUID → 404, inactive → 410, oversized → 413.

- Delivery engine (internal/delivery): fx-managed background goroutine that
  polls for pending/retrying deliveries and dispatches to target type handlers.
  Graceful shutdown via context cancellation.

- Target type implementations:
  - HTTP: fire-and-forget POST with original headers forwarding
  - Retry: exponential backoff (1s, 2s, 4s...) up to max_retries
  - Database: immediate success (event already stored)
  - Log: slog output with event details

- Webhook management pages with Tailwind CSS + Alpine.js:
  - List (/sources): webhooks with entrypoint/target/event counts
  - Create (/sources/new): form with auto-created default entrypoint
  - Detail (/source/{id}): config, entrypoints, targets, recent events
  - Edit (/source/{id}/edit): name, description, retention_days
  - Delete (/source/{id}/delete): soft-delete with child records
  - Add Entrypoint (/source/{id}/entrypoints): inline form
  - Add Target (/source/{id}/targets): type-aware form
  - Event Log (/source/{id}/logs): paginated with delivery status

- Updated README: marked completed items, updated naming conventions
  table, added delivery engine to package layout and DI docs, updated
  column names to reflect entity rename.

- Rebuilt Tailwind CSS for new template classes.

f9a9569015 feat: bring repo up to REPO_POLICIES standards (#6)
All checks were successful
check / check (push) Successful in 8s
## 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
