Serve an event's full stored body over HTTP (closes #157)
check / check (push) Successful in 3m1s
Capping the event log page at 8 KB of body per event left no
in-app way to see a larger one: storage keeps it, but no route
served it, so a payload over the cap was reachable only by an
operator with filesystem access. GitHub pull_request and
multi-commit push payloads, expanded Stripe events and Shopify
orders all routinely clear 8 KB, which is exactly when the tool
is supposed to be useful.
GET /source/{sourceID}/logs/{eventID}/body now serves one whole
body, and the truncation marker links to it when — and only
when — a body was actually cut.
The response is deliberately inert. Its bytes are chosen by
whoever can reach the public receiver and it hands them back
inside the operator's own authenticated origin, so it goes out
as application/octet-stream with Content-Disposition: attachment
and nosniff, and the filename is built from a parsed uuid rather
than from anything in the request. The application CSP is no
help on this path: script-src allows 'unsafe-inline' from
'self', so a document served from this origin could run its own
script.
The body is read in one query and held whole while it is
written. There is no cheaper bound to take. database/sql
exposes no incremental handle on a SQLite blob, and reading
byte ranges with substr does not avoid the cost either: SQLite
materialises the entire column value to evaluate each substr
call, so range reads pay for the whole body once per range
rather than once per download. Measured over a 1 MiB body,
64 KiB ranges cost 11-15x a single read to move the same bytes.
The route is owner-authenticated and ingest is capped at 1 MB,
so the cost is bounded — but at roughly two body-sized
allocations per concurrent download, not one. The driver's
column buffer and the copy database/sql makes in convertAssign
when a []byte column is scanned into a *[]byte are live at the
same time; measured allocation is ~2x the body plus ~45 KB,
about 2 MB at the ingest cap. SQLite's own materialisation of
the column value sits in the driver's allocator outside the Go
heap and is not in that number, so process peak is higher
again: 2x is a floor, not a ceiling. Nothing goes through
renderTemplate, which buffers a whole response before writing
it.
Reading the body before the first header is written also means
an event reaped mid-request cannot produce a torn response: it
is either served whole or 404s cleanly, and both are tested.
The ownership check the log page applies is extracted as
ownedWebhook and shared with the download, so the two cannot
drift apart. A webhook owned by someone else and one that does
not exist are the same 404.
The route registration and the link the template emits are
covered end to end through the production router, so a typo in
either fails the suite rather than leaving the feature dead
behind green handler tests.

chore: consolidate DBURL into DATA_DIR, codebase audit for 1.0.0
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)

refactor: self-contained delivery tasks — engine delivers without DB reads in happy path
check / check (push) Successful in 58s
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. |

feat: implement per-webhook event databases
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
