clawbot 06be075b70 Store events and create deliveries in the delivery engine (closes #544)
check / check (push) Waiting to run
Details 
The receiver, resubmit and replay handlers now read and check the
request and make one call. Engine.StoreEvent stores an event with a
pending delivery for each active target and the totals in one
transaction, then queues them; Engine.CreateReplay does the same for
one replay delivery. The handlers take *delivery.Engine, so the
Notifier interface and its bridge are gone, and the engine's notify is
no longer exported. Archives and CircuitBreakers stay because the
handler tests fake them. The tests that read a queued task moved to
the engine's tests; the handler tests use an engine that is never
started.

clawbot 8406c77949 Store a target's settings as columns (closes #543)
check / check (push) Waiting to run
Details 
A target's settings move from the per-type JSON string in
targets.config to columns: url, headers, timeout_seconds,
forward_query, archive_expiry and archive_rotation. A column a type
does not use stays empty. headers holds the header map as JSON text
through GORM's JSON serializer, and archive_expiry holds a
time.Duration, 0 meaning never. The forms check each setting once,
with the same refusals and messages, and the edit form is filled from
the columns, so the per-type config structs, their parsers and the
"could not be read" branches are gone. A delivery task carries the
six settings in place of the JSON string; tests check that each copy
into a task, and back out of one, keeps all six.

clawbot ded39aa158 Use one recovery routine at start and on every sweep tick (closes #542)
check / check (push) Waiting to run
Details 
Start-up recovery and the 60-second sweep were two parallel sets of
functions doing the same job. recoverDeliveries now does it, run once at
start and then on every tick from one goroutine. A retrying delivery is
scheduled after what is left of its backoff, now if nothing is left, so
backoffElapsed is gone. The run at start still takes every pending
delivery and opens a webhook database whose file is missing; a tick
still takes only pending deliveries untouched for 15 minutes, at most
500, and skips a missing file. A retrying delivery is taken before its
event is read. The README describes one routine.

clawbot 0cdda43e6c Move the archive files into their own package (closes #541)
check / check (push) Waiting to run
Details 
The SQLite archive files the database target writes are now managed by
internal/archive: file names, rotation, the writer of each target,
pruning, renames, the gzipped JSON export, the idle sweep, and the
rename lock, which was Handlers.renameMu. The database target stays in
internal/delivery and writes through archive.Writers; the engine still
closes the writers when it stops, so the stop order is unchanged. The
handlers take the rename lock from archive.Archives.RenameLock, and
rename and evict through archive.Archives.

Exported names drop their Archive prefix in the new package. The tests
moved with the code; the two that check a delivery's recorded attempt
stay in delivery.

clawbot f10440b7cc Store a webhook's retention as a plain day count, 0 meaning forever (closes #539)
check / check (push) Waiting to run
Details 
retention_days loses its column default of 30, and Webhook.RetentionDays
its default tag, so a 0 is stored as 0. The 365000-day stand-in
RetentionForeverDays and the BeforeSave hook that wrote it are gone. The
reaper and the "forever" label read 0 as forever, and the forms accept 0
or 1 to MaxFiniteRetentionDays; a blank field still gives 30 on the new
webhook form and keeps the stored value on the edit form. A negative
value, which the forms refuse, is still read as forever so it cannot put
the reaper's cutoff in the future.

clawbot 40e8ecaab4 Store a target's number of delivery attempts, at least one (closes #540)
check / check (push) Waiting to run
Details 
Target.MaxRetries (max_retries) becomes Target.MaxAttempts
(max_attempts), and the form field, parser and ceiling are renamed to
match. The column is NOT NULL and a check constraint refuses a value
below 1, so every target, whatever its type, is stored with at least
1. 1 is a single attempt with no circuit breaker; above 1 retries
behind the breaker up to that many attempts. Both target forms refuse
0 and less; a blank field on the add target form gives 1, and on the
edit form keeps the stored value. The target page shows the plain
number, and the README's two paragraphs on 0 against 1 become one
sentence.

clawbot 147d58dd96 Say the query logger drops bound values (closes #535)
check / check (push) Waiting to run
Details 
The comment on MaxAccessLogLineBytes said the GORM adapter logs each
statement with the client's parameter written into it. Its
ParamsFilter drops every bound value, so the statement is logged with
its placeholders. The comment now says so and keeps the parts that
still hold: the widest line spends two budgets and the adapter's test
checks it against this constant.

The assertBounded doc no longer claims each line was cut, and the
postReceiver doc no longer explains itself by a log size test that is
gone.

clawbot c7c4ea3340 Send only the Referer's scheme and host to Sentry (closes #548)
check / check (push) Waiting to run
Details 
A Sentry event kept the Referer header verbatim, and a Referer can be
an entrypoint URL: a sender that follows the README's http:// to
https:// redirect sends the URL it was redirected from, and a browser
sends the 404 page's URL under /h/ when it fetches that page's
stylesheet. The Sentry hook now keeps only the Referer's scheme and
host. The access log's reduction moves, unchanged, into a new package,
internal/referer, as SchemeAndHost; the access log and the Sentry hook
both call it there. The comment above sentryKeepsHeader and the
README's Sentry passage say so, and the README's Package Layout lists
the new package.

clawbot 8c05ec4378 Build the binary without cgo (closes #545)
check / check (push) Waiting to run
Details 
make build now builds with CGO_ENABLED=0, and the image builds through
it. The binary's only cgo code was mattn/go-sqlite3, which
gorm.io/driver/sqlite imports and webhooker never opens: every SQLite
file is opened with modernc.org/sqlite and the connection handed to
gorm. Without cgo, mattn's package compiles to a stub nothing calls.

The Dockerfile builds the binary once. The static relink and its
netgo, osusergo and sqlite_omit_load_extension tags are gone, and with
them the Makefile's GO_LDFLAGS and GO_TAGS, which only the relink used.
The test phase keeps cgo for -race. No README or Dockerfile sentence
says the binary needs cgo any more.

clawbot 872e4eb4a1 Drop 'unsafe-inline' from the Content-Security-Policy (closes #530)
check / check (push) Waiting to run
Details 
The delete prompts on the webhook page were inline onsubmit handlers.
Each delete form now carries its question in a data-confirm attribute,
which one submit listener in static/js/app.js asks. The three style
attributes became Tailwind classes, with tailwind.css regenerated, and
the x-cloak rule moved to style.css. The policy now sends
script-src 'self' and style-src 'self'.

The browser test now answers a target's delete prompt no and then yes,
and also loads the sign-in page, the webhook list, the settings and
profile pages and the 404 error page under the policy. The README
states the policy as sent.

clawbot dfe8f3138f Bind 0.0.0.0 to IPv4 only (closes #528)
check / check (push) Waiting to run
Details 
Go listens on any unspecified address with one socket that answers
IPv4 and IPv6, so BIND_ADDRESS=0.0.0.0 also bound every IPv6 address,
which the README says it does not. The listener now uses tcp4 for an
IPv4 address, written plain or IPv4-mapped; :: still binds both. The
server's start hook suppresses contextcheck, as the other start hooks
do.

The image's health check asked for localhost, which wget reached over
::1 only. It now asks for the container's own address: its IPv4
address, or its IPv6 address on an IPv6-only network. A loopback bind
answers neither. The README says such a network needs ::, drops the
bindv6only condition from :: (Go sets that socket option itself) and
names an ss check.

clawbot 0d38aea12c Keep the entrypoint UUID out of webhooker's own logs (closes #531)
check / check (push) Waiting to run
Details 
On the receiver route the access log and the per-entrypoint 429 line
name the route pattern whatever the status. A request chi never routed,
such as a dev-mode CORS preflight to the receiver, logs (unmatched).
The access log keeps only the scheme and host of a Referer. The
received line names the entrypoint and webhook IDs, and the
unknown-entrypoint line logs no path. The pattern is
middleware.ReceiverRoute, which routes.go registers the receiver with.

The README says the proxy's access log holds the UUID and must be
protected like the URL, and that a log target writes the request's
headers as received. Its access-log, rate-limit, Sentry and log-size
passages now match the code.

clawbot c0f7cc29fd Leave a delivery cut off by a stop for the next start (closes #527)
check / check (push) Waiting to run
Details 
Stopping the engine cancels the context every http and slack request is
sent with. An attempt cut off that way was recorded as failed, which for
a target with no retries, or on a last retry, ended the delivery failed
and nothing sent it again.

The shared retry core now records nothing for a failed attempt when the
engine's context is cancelled: no result, no circuit breaker outcome, no
status change, no count in the attempt metrics. The delivery stays
pending or retrying and startup recovery sends it again. A target's own
timeout is still a failed attempt. The README says what happens to an
attempt in flight at a stop and no longer claims every attempt is
recorded.

clawbot f14fe02011 Store delivery and archive times without the monotonic reading (closes #529)
check / check (push) Waiting to run
Details 
finished_at, archived_at and the updated_at stamp a re-dispatch
writes came from a bare time.Now(). The SQLite driver stores a time
as time.Time.String(), which appends the monotonic clock reading
(" m=+…") to a time read from time.Now(). All three now come from
GORM's own clock, NowFunc(), which stamps created_at, so they are
stored in the same form. The tests for each write read the stored
text back.

clawbot 573f7f986a Build the image's static binary with netgo, osusergo and sqlite_omit_load_extension (closes #525)
check / check (push) Successful in 7m24s
Details 
The image's static relink linked glibc's getaddrinfo (from Go's cgo DNS
resolver) and dlopen (from SQLite extension loading). A static binary
still needs glibc's shared libraries at run time for both, and the
Alpine runtime has none. The relink now passes the standard build tags
netgo, osusergo and sqlite_omit_load_extension through a GO_TAGS
variable, which the Makefile's build target hands to go build as -tags
next to GO_LDFLAGS, so the version stamp is composed as before.

clawbot 373a2f828d Describe code in its own terms, not by an earlier build's data (closes #522)
check / check (push) Successful in 8m12s
Details 
Several comments justified code by what an earlier build would have
left in a database or on disk. Each now says what the code does:
reserveSQLiteFile sets the mode on every open whoever created the
file, and expired treats a session lacking a deadline's timestamp as
expired. The comments on retention, resubmitted events, archive
pruning, target headers, the redactor and the delivery result view
drop their mentions of older rows. parseMaxRetries loses its
paragraph on targets saved before the ceiling existed, and neither
BeforeSave nor retentionCutoff cites a migration. Comments only.

clawbot 267d5b12f2 Escape the database path in the SQLite connection string (closes #518)
check / check (push) Successful in 7m13s
Details 
SQLite reads a file: URI's path only up to the first ? or #, and
decodes %XX escapes in it. With a data directory such as
/srv/hooks#1, every database opened the one file /srv/hooks. The
connection string is now built with url.URL, which escapes the path,
and OmitHost keeps a relative path relative.

Tests open databases in a directory whose name holds #, ? and %, and
at a relative path, and check through PRAGMA database_list that each
opened the file asked for. A handlers test comment that blamed # in
the temporary directory's path is dropped, as that is no longer true.

Details 
The schema comes from 001_schema.sql, edited in place before 1.0, so the
README's upgrade procedure, downgrade note, BIND_ADDRESS upgrade note and
remarks about what older builds wrote are removed.

The description of the SQL schema files moves to a new Schema subsection
under Database Architecture, the health check command moves to Version
stamping, and the section is renamed Backup and Restore. The sentences on
session timestamps, file modes and the retention clamp now say only what
the code does.

clawbot c8efbd41d4 Drop Completed Steps from TODO.md; the tracker is the record (closes #112)
check / check (push) Canceled after 0s
Details 
Every issue branch added an entry to the same list, so each branch
conflicted with `next` as soon as another one landed. The tracker already
records what is done, in more detail than the list did.

The Workflow section now says the tracker is that record, in place of the
rule that issue branches leave this file alone. Status points to the 1.0.0
milestone for what is open, and Next Step says @sneak tags `v1.0.0` after
running webhooker in limited production. In Future Steps, each item that
overlaps with what webhooker already does now says what exists and what is
still missing, and the delivery status and retry UI item is gone because the
event log, replay and resubmit cover it.

clawbot 15377f792b Build every database's schema from embedded SQL files (closes #56)
check / check (push) Canceled after 0s
Details 
The main database, each webhook's event database and each archive file
get their schema from SQL files under internal/db/migrations/, one
directory per kind. Opening a file runs, in one transaction, each file
that schema_migrations does not list. GORM stays for queries.
AutoMigrate is gone, tests included.

An event database holds only its own tables now, so the sweep that
removed target rows copied into it is deleted. The association guard
stays: without it a delivery write fails on the missing targets table.

AutoMigrate also had GORM parse every model before a handle was shared.
That is now done on its own: GORM races when two goroutines first use
models that refer to each other.

clawbot f86ab6321d Name Sentry transactions after the route they matched (closes #185)
check / check (push) Successful in 8m52s
Details 
sentryhttp names each transaction after the concrete path, which the
BeforeSendTransaction hook has to withhold, so with tracing on the
transactions would fall into one Sentry group per method, such as
POST /(redacted). A middleware installed beside every sentryhttp
handler now renames the transaction to the method and chi route
pattern once the request is routed, and sets its source to route. The
hook keeps a route-sourced name and withholds every other name as
before. A path that matches nothing at the top level keeps the
withheld name; one that matches no route inside a route group, or
that the group's middleware turns away, is named after the group's
pattern, such as GET /pages/*. Tracing stays off.

clawbot 957de7f99f Make the HSTS max-age configurable with HSTS_MAX_AGE (closes #271)
check / check (push) Failing after 3h11m13s
Details 
HSTS_MAX_AGE, a Go duration, sets the max-age of the
Strict-Transport-Security header. Unset, it is ten years (87600h);
0 sends no header at all. A negative value, or one that is not a
whole number of seconds, stops startup like an unparseable one.
includeSubDomains and preload stay in the header. The value is shown
on /settings and in the startup log, and the README's HSTS section
now says what each part of the header commits the operator to.

- 2026-08-24 Bind the plaintext HTTP listener deliberately, via `BIND_ADDRESS`
defaulting to `127.0.0.1`, and document the reverse-proxy deployment. A
hostname, an empty value or a value carrying a port is a startup error, and
the `Dockerfile` sets `0.0.0.0` because a loopback bind inside a container is
unreachable (https://git.eeqj.de/sneak/webhooker/issues/268). The same commit
removed the shutdown race: `httpServer` is built in the constructor rather
than assigned from the serving goroutine, which orders the write before every
fx hook and rules out the nil dereference a SIGTERM arriving first would have
caused, and `sentryEnabled` is an `atomic.Bool`
(https://git.eeqj.de/sneak/webhooker/issues/226)
- 2026-08-24 Remove inbound request signature verification. The entrypoint UUID
is the authentication secret, so the per-entrypoint shared secret, the
`internal/signature` package, the receiver check, the model fields and the
forms are all gone. This reverses the feature that landed earlier in the same

https://git.eeqj.de/sneak/webhooker/issues/279)
- 2026-08-24 Stamp the build version into the binary and render it in the UI
footer. `script/version` is the single source — `$VERSION`, else
`git describe --tags --always --dirty`, else `unknown` — so a `make build`
binary and a `make docker` image from one checkout report the same thing, and
nothing in it varies between two builds of the same commit, which the release
gate's byte-identical assertion would catch
(https://git.eeqj.de/sneak/webhooker/issues/253)
- 2026-08-24 Derive cookie `Secure` and CSRF strictness from the request
transport rather than from `WEBHOOKER_ENVIRONMENT`. Behind a real TLS proxy
with the environment left at its `dev` default, the session cookie silently
lost `Secure` while the CSRF cookie on the same response kept it.
`X-Forwarded-Proto` is now matched case-insensitively on its first
comma-separated element, so `HTTPS` and `https, http` no longer fall to the
relaxed CSRF path (https://git.eeqj.de/sneak/webhooker/issues/269)
- 2026-08-24 Roll back a failed webhook deletion instead of committing it. A
failing delete committed whatever had already succeeded, hard-deleted the
per-webhook event database anyway, and redirected as though it had worked —
orphaned config plus permanently destroyed history, reported as success. All
three delete positions now roll back with the event database intact
(https://git.eeqj.de/sneak/webhooker/issues/262)
- 2026-08-24 Name a deleted target on its historical deliveries, marked
`(deleted)`, rather than leaving the event log unable to say where a delivery
went. A deleted target's credentials stay masked exactly as a live one's, and
it cannot become deliverable again through the receiver, resubmit, replay, the
edit form or the toggle (https://git.eeqj.de/sneak/webhooker/issues/211)
- 2026-08-24 Bound both request-controlled `/metrics` label dimensions, so the
unauthenticated receiver is no longer a memory-exhaustion vector: `handler`
carries the chi route pattern, and `method` folds anything chi cannot route
onto a single `(unmatched)` sentinel. Both were reproduced before the fix —
300 random method tokens took the series count from 106 to 7,631, and path
flooding reached 62,532 — and a label audit across a live scrape found no
third unbounded dimension (https://git.eeqj.de/sneak/webhooker/issues/254,
https://git.eeqj.de/sneak/webhooker/issues/261)
- 2026-08-24 Validate `max_retries` on both target forms. `abc`, `2.7` and `-5`
silently became 0 — fire-and-forget — including on the edit path, where it
destroyed a working value, and `999999999` stored verbatim. The ceiling of 20
is the `max` both templates already declared
(https://git.eeqj.de/sneak/webhooker/issues/221)
- 2026-08-24 Resubmit a stored event as a new undelivered event, so a backend
under development can be tested against real captured traffic. Per-delivery
replay cannot serve that: it re-sends one finished delivery to its own
original target, and a target created for a dev backend has no prior delivery
to replay. Resubmit re-injects the stored event at the top of the receiver
path and fans it out to whatever targets are active now
(https://git.eeqj.de/sneak/webhooker/issues/250)
- 2026-08-20 Take an exclusive lock on `DATA_DIR` at startup, so two instances
on one directory cannot both deliver
(https://git.eeqj.de/sneak/webhooker/issues/201)
- 2026-08-20 Shut down the app when the HTTP listener fails. The `OnStart` hook
returned as soon as the serving goroutine was spawned, so a failed listen left
fx reporting RUNNING and a live process with nothing bound — invisible to
systemd and Docker restart policies
(https://git.eeqj.de/sneak/webhooker/issues/200)
- 2026-08-20 Stop target credentials leaking into the per-webhook event
databases (https://git.eeqj.de/sneak/webhooker/issues/206), log SQL with
placeholders rather than bound values
(https://git.eeqj.de/sneak/webhooker/issues/207), and fail loudly on half-set
metrics auth credentials (https://git.eeqj.de/sneak/webhooker/issues/205)
- 2026-08-20 Read queue depths with `Find`, not `Scan`. `Scan` swaps GORM's own
trace recorder in for the logging adapter, and that recorder does not
implement `gorm.ParamsFilter`, so those statements logged their bound values
interpolated and bypassed the suppression above. The two units gated green
against a `next` that lacked the other, and `next` went red when both landed
(https://git.eeqj.de/sneak/webhooker/issues/234)
- 2026-08-20 Render per-attempt delivery detail in the event log
(https://git.eeqj.de/sneak/webhooker/issues/202) and add replay of a
terminally failed delivery (https://git.eeqj.de/sneak/webhooker/issues/203)
- 2026-08-20 Expose delivery metrics on `/metrics`
(https://git.eeqj.de/sneak/webhooker/issues/209) and document the backup,
restore and upgrade procedures
(https://git.eeqj.de/sneak/webhooker/issues/210)
- 2026-08-20 Add a `webhooker resetpw` subcommand and a bootstrap banner. The
admin bootstrap password was printed once among roughly 45 fx lines, and under
`docker run -d` went to container logs subject to rotation; there was no reset
path at all, so recovery meant hand-deleting the users row, documented
nowhere. The password is read from stdin or generated, never from argv where
`/proc` would publish it (https://git.eeqj.de/sneak/webhooker/issues/208)
- 2026-08-20 Add `ALLOWED_EGRESS_CIDRS`, an allowlist-only escape hatch for the
SSRF guard, so a self-hosted proxy can forward into the operator's own
network. The guard's always-blocked set cannot be reopened by configuration
(https://git.eeqj.de/sneak/webhooker/issues/204)
- 2026-08-20 Harden operator-set target headers, which were carried unsafely
across a redirect (https://git.eeqj.de/sneak/webhooker/issues/233)
- 2026-08-20 Add a target edit form with headers and timeout fields
(https://git.eeqj.de/sneak/webhooker/issues/127)
- 2026-08-18 Raise `script/test`'s per-package timeout from 30s to 90s, matching
the org-wide backstop. `go test` applies `-timeout` per package, and
`internal/handlers` had grown past the old budget: a cache-defeated build
failed outright at `GOMAXPROCS=4`, and every run under deliberate host load
breached 30s. The measurement table lives in the script (#194)
- 2026-08-18 Re-sync `REPO_POLICIES.md` from `prompts`. The local copy was stale
and still mandated a 20s test target with a 30s timeout, which the org
replaced with a 60s cap and a 90s backstop. A synced copy is not a source;
reading it as one nearly produced a PR against `prompts` proposing a change
already merged there (#196)
- 2026-08-18 Report handler panics through the logger and answer 500. chi
v1.5.5's `Recoverer` scans for a `panic(0x` frame the runtime no longer emits,
then indexes `pkg[-1:]`, so it panicked inside its own stack printer before
writing a byte: the recovery never ran, the client got a dropped connection
instead of a 500, and the original panic was lost. A local middleware replaces
it, bounded by `MaxPanicLogLineBytes` (#187)
- 2026-08-18 Route GORM's logger through `slog` and bound it. Every `gorm.Open`
left `logger.Default` in place at `Warn` with `IgnoreRecordNotFoundError`
false, so **every record-not-found printed the fully interpolated SQL to
stdout** — including the client-chosen path on `/webhook/{uuid}` and the
submitted username on the login form, at no level the operator set and outside
`internal/logger` entirely. Three call sites, not the two the issue named
(#178)
- 2026-08-18 Bound every `slog` line against client-chosen text. Eight sites
reachable unauthenticated, found by reading every `slog` call in the tree
rather than only the one reported; the budget moved to a shared
`internal/logfield` so no second truncation exists. `DEBUG` being off by
default is not a bound and is not treated as one (#176)
- 2026-08-18 Stop a slow host turning a login-guard test into a segfault. A
non-fatal `assert` on an acquire result was dereferenced on the next line, so
one timing miss killed the whole `internal/middleware` binary and reddened CI
for unrelated PRs. The fix also removed a real production race — `acquire`
could shed a request with a slot standing free, because Go picks uniformly
among ready `select` cases (#186)
- 2026-08-18 Send the chi route pattern to Sentry rather than the concrete path.
The receiver's path carries the entrypoint capability token, so every Sentry
event from `/webhook/{uuid}` shipped a live credential to a third party.
Request `Data`, `QueryString`, `Cookies` and `Env` are dropped and headers
reduced to an allowlist (#179)
- 2026-08-18 Read form fields from the POST body only. `r.FormValue` merges the
query string, so a login could be driven by URL parameters — putting the
password somewhere that lands in access logs, proxy logs and browser history
(#160)
- 2026-08-18 Verify login credentials before spending rate-limit budget, so a
flood of wrong passwords cannot lock out the account it is guessing at. The
manager took this decision rather than stall the queue; it is flagged on the
issue for reversal (#150)
- 2026-08-18 Run all linting in Docker via `Dockerfile.lint`. Host lint was
wrong in both directions from version skew and shared caches. `script/lint`
asserts the summary line, because `--no-cache-filter` silently ignores a stage
name it does not match — the flag that makes the gate meaningful fails open
(#109)
- 2026-08-18 Serve an event's full stored body over HTTP. The list query
truncates for rendering, and that truncated value was the only way to read a
body, so the full payload was unreachable (#157)
- 2026-08-18 Bound the access log line against client-chosen text.
`internal/logfield` budgets by _encoded_ bytes, not runes, so a handler's JSON
escaping cannot multiply a field past its allowance (#146)
- 2026-08-18 Mark superseded CI commits `failure` rather than `skipped`. A
skipped run rolls up green, so a commit that was never tested reported success
(#152)
- 2026-08-18 Set `fx.StopTimeout` inside the container stop grace, so shutdown
hooks are bounded by a deadline the orchestrator will actually honour rather
than being killed mid-flush (#134)
- 2026-08-17 Bucket IPv6 rate-limit keys by `/64`. A single allocation hands out
2^64 addresses, so per-address keying let one client mint unlimited buckets.
Manager decision, recorded on the issue (#125)
- 2026-08-17 Correct release-blocking README and startup-warning inaccuracies,
including claims about behaviour the code does not have (#151)
- 2026-08-17 Fetch and verify Alpine.js at build time against
`static/vendor.sha256` instead of committing the minified blob, so the
dependency is pinned by hash rather than by trust (#145)
- 2026-08-17 Bound the event log's rendered bodies in the query itself, so a
large stored payload cannot be read into memory just to be truncated for
display (#135)
- 2026-08-17 Mask the `http` target's destination URL in the UI: it can carry a
bearer credential in its path or query, and was rendered verbatim. Manager
decision to mask unconditionally (#115)
- 2026-08-14 Bound shutdown hooks by their stop context, so a hook that hangs
cannot hold the process past its grace period (#102)
- 2026-08-14 Render templates via a buffer rather than the `ResponseWriter`, so
a template error part-way through cannot commit a 200 and then fail — the
response is written only once it is whole (#123)
- 2026-08-14 Align the session codec's max-age with the 7-day absolute cap. The
codec accepted cookies the session layer considered expired, so the cap was
enforced in one place and not the other (#108)
- 2026-08-12 Warn when `TRUSTED_PROXIES` is empty in production, where the safe
default silently discards forwarded headers and every client rate-limits as
the proxy's address (#149)
- 2026-08-12 Bound the receiver rate limit per client IP across the whole
`/webhook/*` route. The existing limiter keyed on the request path and
`/webhook/{uuid}` matches any single segment, so a client that invented a
fresh path per request minted a fresh bucket per request: the limit on the
only unauthenticated endpoint bounded nothing in aggregate, and every request
still cost an entrypoint lookup before it 404ed. An outer limiter keyed on the
client address alone now bounds that, chained in front of the unchanged
per-entrypoint limiter (#139)
- 2026-08-12 Correct release-blocking documentation inaccuracies: the README
promised manual redelivery in the present tense in three places when nothing
implements it (the same false claim also sat in the doc comment that was its
source text), the env table omitted `RETENTION_SWEEP_INTERVAL`, and `TODO.md`
itself omitted five landed units (#141)
- 2026-08-12 Make the CI gate execute the checks it reports on. The workflow now
writes a build-context fingerprint before calling `script/cibuild`, so a code
commit invalidates the `COPY` layer of the lint and builder stages while a
docs-only commit still replays from cache; a superseding run also rewrites the
`failure` status Gitea leaves on commits it cancelled and never tested.
Verified by pushing a deliberately broken test and watching CI go red (#119)
- 2026-08-12 Require a positive `RETENTION_SWEEP_INTERVAL`: a non-positive value
reached `time.NewTicker` in both the retention reaper and the archive sweeper,
panicking two goroutines with no recover after startup had already reported
success (#140)
- 2026-08-12 Bound the `X-Forwarded-For` scan's allocation to the hop cap: the
reverse walk cuts entries with `strings.LastIndexByte` instead of joining and
splitting, so a 1 MB header allocates 16 bytes rather than 1.6 MB per request
on the unauthenticated receiver. Semantics proven unchanged by differential
testing against the previous implementation (#133)
- 2026-08-12 Cap the `X-Forwarded-For` hop walk at 64 entries, so an
attacker-supplied chain cannot burn unbounded CPU in the rate-limit key
function; running off the end falls back to the peer address (#124)
- 2026-08-12 Gate forwarded-header trust behind a `TRUSTED_PROXIES` CIDR list:
all three rate limiters key on the connection's own address unless the direct
peer is a configured proxy, in which case `X-Forwarded-For` is walked right to
left for the first non-proxy hop. Default trusts nothing, and a
set-but-unparseable value aborts startup. Before this, any client could mint a
fresh bucket or drain another's by rotating a spoofed header (#88)
- 2026-08-11 Web UI cleanup: nav terminology unified on Webhooks, the Profile
settings placeholder removed, a progressive-enhancement copy button for the
entrypoint URL, and retention form copy that states the actual policy
(deletion by the reaper, 0 retains forever) (#57)
- 2026-08-11 Mask the webhook credential in delivery errors and logs: Go embeds
the request URL in `*url.Error`, so every transport failure persisted the full
Slack webhook URL into the per-webhook event database via
`DeliveryResult.Error`, a field a future REST API would have served.
`maskURLError` drops path, query and userinfo while preserving the wrapped
cause, so `errors.Is`/`As` and `Timeout()` still work and DNS, TLS and timeout
failures still read differently (#118)
- 2026-08-11 Rate-limit the public webhook receiver endpoint
(`RECEIVER_RATE_LIMIT`, default 120/min), keyed on client IP plus entrypoint
path so one entrypoint cannot exhaust another's budget; over-limit requests
get 429 with `Retry-After`. It was the one unauthenticated, internet-facing
endpoint with no limit at all (#64)
- 2026-08-11 Enforce the body size limit before CSRF parses the form:
`MaxBodySize` is now first in all four form-parsing route groups, so an
oversized request is rejected with 413 instead of being read in full by the
CSRF middleware before any cap applied (#90)
- 2026-08-11 Mask target config on the source detail page, which rendered the
stored blob verbatim and so exposed the Slack incoming-webhook URL — a bearer
credential that cannot be revoked per-holder. Config reaches the template only
as a `TargetView` of labelled fields, and header values are rendered as a
count (#113)
- 2026-08-11 Allow `retention_days` of 0 to mean retain forever, via a sentinel
written in `BeforeSave` so the GORM column default cannot win the race. Also
bounds the reaper's cutoff arithmetic: day counts above 106751 overflowed
`time.Duration` and wrapped the cutoff into the future, where every row
matched and the sweep deleted everything (#79)
- 2026-08-09 Inactivity-based session timeout: sliding idle expiry
(`SESSION_IDLE_TIMEOUT`, default `24h`) refreshed on authenticated requests,
with the 7-day absolute cap kept as an independent backstop that activity
never extends (#66)
- 2026-08-09 Restart recovery and the 60s retry sweep terminally fail an
orphaned `retrying` delivery whose target type no longer supports retries,
recording a `DeliveryResult` with the reason instead of leaving the delivery
stuck forever (#82)
- 2026-08-09 Root the delivery engine's worker pool and the retention reaper's
sweep loop at `context.Background()` rather than the fx `OnStart` hook context
(#97), which carries fx's 15s start timeout and killed both roughly fifteen
seconds after boot: the proxy silently stopped delivering webhooks entirely,
and the reaper never ran a single sweep under its default one-hour interval
- 2026-08-09 Archive writer lifecycle (#89): deleting a webhook (or its last
`database` target) evicts the cached archive writer and closes its handle
while deliberately leaving `archive-{webhookID}.db` on disk, and a new
`ArchiveSweeper` prunes idle archives on the existing
`RETENTION_SWEEP_INTERVAL` without ever creating an archive file
- 2026-08-09 Configuration parsing fails loudly on set-but-unparseable
environment values: `envInt` removed in favour of `envPositiveInt` plus a
`PORT` range check, `envBool` now parses with `strconv.ParseBool`, and
defaults apply only to unset variables (#80)
- 2026-08-07 Automatic event retention cleanup based on `retention_days`,
deleting expired events, deliveries, and delivery results from each
per-webhook event database (#63)
- 2026-08-07 Update golangci-lint to v2.12.2 (Docker image digest in
`Dockerfile`, release-archive sha256 pins in `script/bootstrap`), adopt the
canonical `.golangci.yml` (v2 `linters.settings` layout so
`lll`/`funlen`/`cyclop`/`dupl` thresholds actually apply), and fix all newly
surfaced lint findings
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints, Makefile
shims, README Entrypoints section
- 2026-03-25 pin golangci-lint Docker image for linting (#55)
- 2026-03-18 CSRF middleware detects TLS per-request, fixing login over plain
HTTP and behind reverse proxies (#54)
- 2026-03-17 root path redirects based on auth state (#52)
- 2026-03-17 CSRF protection, SSRF prevention for HTTP delivery targets with DNS
rebinding defense, and per-IP login rate limiting (#42)
- 2026-03-17 Slack target type for incoming webhook notifications (#47)
- 2026-03-17 Dockerfile absolute paths and static linking (#49); absolute dev
DATA_DIR default and clarified env docs (#46)
- 2026-03-05 security headers middleware, session regeneration on login, request
body size limits (#41)
- 2026-03-04 tests for delivery, middleware, and session packages (#32); removed
the build-architecture global (#31)
- 2026-03-04 1.0 MVP merge: Webhook/Entrypoint/Target rename, core delivery
engine with bounded worker pool and circuit breaker, parallel fan-out,
per-webhook event databases, management UI (#16)
- 2026-03-01 repo brought to REPO_POLICIES standards; TODO.md folded into README
(#6)
@sneak runs webhooker in limited production, then tags `v1.0.0`. Merging `next`
into `main` is a separate act from tagging and waits on neither of those: `next`
is kept mergeable at all times, which is the point of the branch.

handler enforcement; global limits must not apply to receiver endpoints)
- API key authentication for programmatic access (APIKey model exists; Bearer
token middleware does not)
- Per-webhook rate limits, set in the web UI and enforced in the receiver
handler, on top of the receiver's existing limits, which `RECEIVER_RATE_LIMIT`
sets for the whole server (see Rate Limiting in the README)
- API key authentication for programmatic access (the `APIKey` model exists, but
nothing creates a key and no middleware checks one)
- REST API v1
- CRUD for webhooks, entrypoints, targets
- event viewing and filtering endpoints
- event redelivery endpoint
- OpenAPI specification
- Analytics dashboard: success rates, response times, volume
- A remember-me option at login
- Analytics in the web UI: response times summarised per webhook or per target,
and figures for all webhooks together. The webhook page already shows event,
delivery and failure counts and failure percentages, the target list counts
each target's deliveries, the event log and each event's page show every
attempt's duration, and `/metrics` carries server-wide counts and delivery
durations
- A remember-me option at login. Every session already survives a browser
restart: it lasts up to 7 days, and ends sooner after `SESSION_IDLE_TIMEOUT`
(default 24 hours) without activity
- Password reset flow for a forgotten password over the web. The authenticated
password _change_ flow already landed, and a lost password is recoverable from
the console with `webhooker resetpw`
