A delivery target URL is itself a credential: a Slack incoming
webhook URL is a bearer token. Three paths still reproduced it
in full.
Transport failures were the worst of them. net/http embeds the
request URL in every *url.Error it returns, so any DNS, TLS,
timeout or dial failure wrote the whole webhook URL into
DeliveryResult.Error — on disk, in the per-webhook database,
behind a json tag that a REST API would serialize.
maskURL moves to url_mask.go and is exported as MaskURL, and
maskURLError joins it: it rebuilds the *url.Error with the URL
masked, keeping the operation and the wrapped cause, so a
refused connection still reads differently from a DNS failure
or a timeout and errors.Is/As/Timeout still work. It is applied
where the errors are raised — executeHTTPRequest, shared by the
Slack and HTTP targets, and the request-construction paths — so
downstream wrapping is safe by construction. url.Parse embeds
the URL too, so ValidateTargetURL's parse branch gets the same
treatment; its error is logged and shown.
The SSRF rejection log now records only the masked URL, and
loadTargetMap hands the event log page TargetViews and a
delivery projection instead of raw target rows, so the stored
config blob has no path to that template either.
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)
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.
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
