clawbot debe588bba Seed the retention tests 50 rows per insert, not 500 (closes #198)
check / check (push) Waiting to run
Details 
Three retention tests made internal/database the slowest test package, mostly by seeding thousands of rows 500 per insert: the SQLite driver finds each parameter's value by scanning the statement's arguments from the first until it reaches that parameter's, so binding grows with the square of the parameter count. They now seed the same rows 50 per insert, about three times faster; no test case or assertion changes. The package drops from 13 to 22s to about 7s. What keeps make test above the 20s target is now mostly the cold -race compile of the tree, which moves with host load. The 90s per-package timeout stays; script/test's header records the new figures.

clawbot e8379272ae Load Alpine's CSP build so the UI's directives run (closes #371)
check / check (push) Waiting to run
Details 
Every page's Content-Security-Policy forbids eval, which the standard Alpine.js build needs, so no directive ran in a browser: both add forms on the webhook page showed open, and events in the event log could not be collapsed. The UI now loads Alpine's CSP build (@alpinejs/csp 3.14.9 in 3p/); the policy is unchanged. Each directive names a property or method of a component registered in static/js/app.js (collapsible, targetForm), and each card holds its own x-data. A browser test, built only with the browser tag, loads the webhook page and the event log under the real headers; make test-browser runs it in Docker. New test-only dependency chromedp, which raises golang.org/x/sys to 0.47.0.

clawbot 3e209bfe4e Drive the archive reopen debounce test from a clock (closes #190)
check / check (push) Waiting to run
Details 
The archive writer's reopen debounce test made two writes that had to land inside the real 2-second window, then slept 2.1 seconds to cross it, so a slow host could turn correct code red. The archive writer now reads the time for its reopen debounce from a clock field, time.Now in production, and the test moves that clock instead of sleeping: two writes at one instant open the file once, and a write one debounce later closes and reopens it once. Removing the debounce check fails the test. This was the last test whose result depended on real elapsed time.

clawbot 88b961c115 Keep each model's parent out of its JSON (closes #177)
check / check (push) Waiting to run
Details 
Every reference from a model to the record it belongs to (a target's or entrypoint's webhook, a webhook's or API key's user, an event's webhook and entrypoint, a delivery's event and target, a delivery result's delivery) is now tagged json:"-", so a preloaded model can be marshalled without the encoder recursing between parent and child. References to child records stay. Tests marshal each of the nine references set, preloaded where it matters, and check the parent's id is absent, so deleting or restoring any one tag fails a test; preloading still fills each reference.

clawbot dc9deda173 Write a form-error page's status only after it renders (closes #128)
check / check (push) Waiting to run
Details 
Six form-error paths (the login error and the webhook form's validation and name-taken branches) called WriteHeader before rendering, so if the form page's own template failed, the answer kept its 400 or 409 status with an error body instead of a 500. The new renderTemplateStatus renders into the buffer and writes the status only after the page has rendered; renderTemplate sends 200 through it, and those handlers pass their status to it. No handler calls WriteHeader before a render. Login-form tests show the 400 page still renders in full and a failing template answers 500.

clawbot c706199389 Name the CI build step after what the image runs (closes #175)
check / check (push) Waiting to run
Details 
The workflow's build step was named "Build Docker image (runs make check)", but the image has never run make check. It is now named for what the image runs: make fmt-check, golangci-lint, make test and make build. No other step name or comment in the workflow names something it does not run. In the README, the Prerequisites bullet now says Docker is needed for make lint and so for make check, and the sentence about what runs on the host is limited to the steps make check runs.

clawbot d52cac1ec6 Toggle only a target's active state, so it cannot undo an edit (closes #431)
check / check (push) Waiting to run
Details 
The target toggle loaded the target, flipped its active flag and saved the whole row, so an edit of the same target's name or settings saved in between was written back over and lost, although it reported success. The toggle now updates only the active column, so it can no longer undo an edit. A test saves an edit just after the toggle has read the target and shows the edit survives and the state flips. The entrypoint toggle is unchanged, since an entrypoint has no edit form.

clawbot 0f9b68a0e8 Build the middleware test cookie stores with the production constructor (closes #154)
check / check (push) Waiting to run
Details 
The middleware tests built their cookie stores by setting store.Options by hand, which left the securecookie codecs at the library's 30-day default instead of the 7-day cap production sets, an invisible divergence that would outlive the next change to store construction. The test store constructor moves from internal/session/export_test.go into internal/session/testing.go so other packages can reach it, and the two middleware test helpers build their stores through it. No test in the repo builds a cookie store by hand any more, and no assertion changes.

clawbot 8cf5acaf1d Justify the handlers tests' start limit with a measurement (closes #225)
check / check (push) Waiting to run
Details 
The internal/handlers tests were load-fragile because every test app hashed the admin password at 64 MB; that went with the cheaper test hashing already on next, and measuring under the host's real load found nothing left to fix in how the tests run. The comment on newTestApp now says its start limit, fx's default, is there to catch a start that hangs, and that the slowest measured start is far inside it. The header of script/test gives current figures in place of ones from before that change. Neither limit changes, and no test changes.

clawbot 9ade217222 Show each webhook's activity in the webhook list (closes #394)
check / check (push) Waiting to run
Details 
Each entry in the webhook list at /hooks now shows when its last event arrived (or "No events yet"), how many of its deliveries failed in the last 24 hours, in red when not zero, and how many entrypoints and targets are inactive, as in "4 targets, 1 inactive". The figures come from the event totals row and the statistics pane's own query, so the list no longer counts every stored event and its event count matches the pane's. A webhook whose event database cannot be read says so in its entry; the rest of the list still shows. A failed read of entrypoints or targets from the main database now returns an error page instead of showing zero.

clawbot 5551f75251 Say at the receiver route where its 1 MB body cap lives (closes #173)
check / check (push) Waiting to run
Details 
The receiver route /h/{uuid} has no MaxBodySize middleware, unlike the page route groups; its 1 MB cap is enforced in the handler, which owns the response senders see. Nothing at the route said so, so a reader could take the receiver for uncapped or remove the only bound on the one unauthenticated endpoint. The route registration and the handler's body-reading function now say where the cap lives and why. A routing test sends a body of exactly 1 MB and one a byte over through the production router and pins that only the second is refused, with the handler's 413 and message.

clawbot fd036774f9 Name each database target's archive for its webhook and target (closes #376)
check / check (push) Waiting to run
Details 
Each database target now writes its own archive file, archive-WEBHOOKNAME-TARGETNAME-TARGETID.db, named by delivery.ArchiveFileName, in place of one archive per webhook keyed on its UUID. Renaming a webhook or a target renames its archive files (with any -wal and -shm) before the new name is saved, never over an existing file, and moves every one back if a rename or the save fails. The webhook edit, the target edit and target creation share one lock so no two interleave. Deleting a webhook or target leaves its files on disk. Nothing looks for the old archive-WEBHOOKID.db files. The README gives the naming and the recovery steps.

clawbot 21aafbf928 Remove the no-op MAINTENANCE_MODE setting (closes #317)
check / check (push) Waiting to run
Details 
MAINTENANCE_MODE did nothing but make the healthcheck JSON report maintenanceMode: true; no request was ever served differently, so an operator who set it expecting requests to be refused got nothing. It is removed from the configuration, the startup configuration log line, the healthcheck JSON, the README and the Settings page, together with the uncalled Server.MaintenanceMode method and the healthcheck's dependency on the configuration. A leftover value in an environment is ignored like any other unknown variable.

clawbot c87b469dcd Let a handler flush or set a write deadline through the access log and metrics (closes #191)
check / check (push) Waiting to run
Details 
The access log's response writer and the metrics middleware's writer hid the writer beneath them, so a handler's flush, hijack or write deadline set through http.ResponseController failed with "not supported" behind them. The access log's writer now has Unwrap. The metrics middleware calls the library's public Measure with a writer of our own that has Unwrap, in place of std.Handler's writer, so the middleware order and what metrics record are unchanged. A test over a real connection sets a write deadline and flushes, metrics on and off, on a global route and in an admin page group, and fails without either Unwrap.

clawbot b14b27b78b Serve the delivery duration histogram from boot (closes #267)
check / check (push) Waiting to run
Details 
The delivery duration histogram was registered only when a delivery first ran, so until then /metrics had no series for it and a dashboard or alert on it saw nothing at all rather than zero. Each of the four target types now has its series registered at boot with zero counts, so the histogram is served from the first scrape. Tests pin that all four series are present before any delivery, on the metrics registry and through the production router.

clawbot 287e47df7f Add a read-only Settings page for the loaded configuration (closes #402)
check / check (push) Waiting to run
Details 
A new page at /settings, linked from the navigation bar and behind the login, lists every configuration field the server loaded at startup: its environment variable, the README table's description, and the value in effect. METRICS_PASSWORD and SENTRY_DSN show only as set or not set; their values are replaced before rendering and never reach the template. The route is GET only and its group is built like the other admin page groups. Tests set the credentials one at a time so each value shown is checked against its own field and a set secret never appears in the page.

clawbot 8b5541734e Run script/test quietly with coverage, rerun failed tests verbosely (closes #315)
check / check (push) Waiting to run
Details 
script/test now runs the suite once with -race -cover and no -v. On a failure it reruns only the failed top-level tests, with -v, in the packages that failed, then exits non-zero whatever the rerun shows. A green run stays quiet, and a red one ends with the failing tests' verbose output, which the Docker build's 2 MiB log limit can hold; a verbose rerun of every package would pass that limit again. A failure that names no test (a build error, a timeout) skips the rerun, since the quiet run already prints that package's output. The timeout and parallelism are unchanged.

clawbot c513816a55 Refuse [::], 0.0.0.0, IPv6 multicast and documentation space (closes #341)
check / check (push) Waiting to run
Details 
On the build host a connection to [::] reaches a listener on ::1, and one to 0.0.0.0 reaches 127.0.0.1, so a delivery target at either reached this host's loopback past the guard. 0.0.0.0/32 and ::/128 are now in alwaysBlockedNetworks, which no allowlist opens; an allowlist reaches loopback only through an entry covering a loopback address. IPv6 multicast (ff00::/8) and documentation space (2001:db8::/32) are refused by default and reopen when listed.

Every default blocklist entry has a one-line comment, each list is pinned on its own, and tests refuse each address at target creation and at delivery. The README and the rules above each list match.

clawbot 2bb4683512 Discard fx's own log in tests that build an fx app (closes #230)
check / check (push) Waiting to run
Details 
Every test that builds an fx app with fxtest.New (handlers, server, resetpw, gormlog, config) now passes fx.NopLogger, so fx's own log no longer goes to t.Logf. A hook still running after a start or stop timeout can then no longer write to a test that has already returned, which the race detector reported as a data race. What the tests assert is unchanged, and nothing about the race detector is suppressed.

check / check (push) Waiting to run
Details 
Saving, deleting, activating or deactivating a webhook, entrypoint or target, and signing out, now land on their page with a one-line notice such as "Webhook deleted." or "Signed out.". The redirect carries a fixed code that maps to fixed text; an unknown code shows nothing, so nothing from the URL is ever echoed. One partial in the page layout shows the notice on every page, and replay and resubmit now use the same codes and partial. Error pages show no notice.

clawbot b78abdc9da Drop TODO.md's stale docs-only cache caveat (closes #421)
check / check (push) Waiting to run
Details 
Since the build context carries .git and the CI fingerprint is the hash of the commit being checked, every commit's check runs the build, docs-only commits included. TODO.md's caveat that a docs-only commit replays from the layer cache was no longer true, and the README's "CI gate honesty" section already says how a check runs, so the paragraph is removed.

clawbot c23ffbac65 Widen the webhook page by half so an entrypoint URL fits on one line (closes #350)
check / check (push) Waiting to run
Details 
The webhook page's maximum width goes from 72rem (1152 px) to 108rem (1728 px), half again as wide, so an entrypoint URL stays on one line in 1920- and 1440-pixel windows; the statistics pane and both columns widen with it. The title row now wraps, so a phone-width window no longer scrolls sideways.

The width is an inline style: static/css/style.css is linked by no page, and the committed Tailwind stylesheet has no class that wide. The webhook list, the event log, the navbar and the footer stay at 72rem.

check / check (push) Waiting to run
Details 
The http and slack targets sent the constant User-Agent webhooker/1.0. They now send webhooker/ followed by the version the build stamped, the same value the footer shows, built in one place on the delivery engine. User-Agent stays a reserved header and is still set after the target's configured headers, so a configured one cannot override it. Tests check the header each target sends against a known version, and that a configured User-Agent is replaced.

clawbot eb4c4cc849 Serve /metrics from a registry of its own (closes #227)
check / check (push) Waiting to run
Details 
A second metrics-enabled router in one process panicked on a duplicate collector registration, because every collector registered on Prometheus's global default registry. metrics.NewRegistry now builds one registry with the Go runtime and process collectors; fx provides it and the delivery metric set built on it. The middleware builds its HTTP recorder once on that registry (NewForTest on a fresh one), the engine and handlers take the metric set from fx, and nothing registers on the global default any more.

/metrics is served from the new registry with the same series names, labels and auth. A test builds two metrics-enabled routers in one process.

clawbot cb7bafab17 Derive the image's version from the .git in the build context (closes #366)
check / check (push) Waiting to run
Details 
upaas uploads its clone as a tar context, which .dockerignore does not filter, so its builds already carried .git; the unknown default of the VERSION build arg is what stamped them. The image now derives its version itself: ARG VERSION has no default, so make build falls back to script/version, which runs git describe on the copied .git; a VERSION build arg still wins.

.dockerignore sends .git without its config in a directory context and no longer leaves out tracked files, which would mark the tree -dirty. The builder installs git, trusts /build as a safe.directory, and fails when .git is present but the version comes out unknown. A shallow single-branch clone stamps its short commit.

check / check (push) Waiting to run
Details 
Every 400, 403, 404 and 500 on an admin page now answers with an error page in the normal layout: the status, one fixed line explaining it, and a link back to the webhook list, or to sign-in when nobody is signed in. Unknown paths reach it through the router's not-found handler, a refused form token through the CSRF middleware, and a panic through a recoverer each admin page route group installs first. Status codes are unchanged, and the page always sends Cache-Control: no-store.

If the error page fails to render, the answer is the same status in plain text; if it panics, the answer is a 500. The receiver, the healthcheck and /metrics keep their plain answers.

clawbot 38157d8936 Say how to allow a refused private target address (closes #398)
check / check (push) Successful in 3m16s
Details 
Refusing an http or slack target whose address is private or reserved, on add or edit, now adds one sentence: such addresses are refused by default, and the server's ALLOWED_EGRESS_CIDRS setting allows named networks, with a pointer to the README section. It suggests no value, so it never points at allowing everything.

Metadata refusals get no such sentence. To tell them apart, the default blocklist's public addresses now have their own list, blockedPublicNetworks, still checked after the allowlist; a test pins which addresses each list refuses and how listing opens them, unchanged from before.

check / check (push) Successful in 3m44s
Details 
A logged-out GET of an admin page now redirects to /pages/login with its path and query in a next parameter, when they fit in 2048 bytes. The login form carries next as a hidden field; a successful login redirects there, and a failed one shows the page again with the same next. A POST still redirects to plain /pages/login.

The value is client-chosen, so every read of it goes through one check: after percent-decoding it must start with exactly one / and contain no backslash or control character; anything else becomes /. gosec's open-redirect rule is suppressed on the two redirects that follow it. The login page's navigation bar no longer links to itself.

Details 
The webhook page opens with a statistics pane: entrypoints and targets, deliveries in progress, the last arrival, the retention period; events, deliveries and failures, lifetime and within retention; and events, failures and failure percentage over 10 minutes and 24 hours.

Running totals, one row per target plus one for events, sit in each webhook's event database and are written in the same transaction as the rows they count; retention prunes in paused, stoppable batches and subtracts what it removes. Window figures are index-range counts on a new finished_at column. An existing event database must be recreated.

Details 
The webhook page and everything under it move from /source/ID to /hook/ID; the list and new-webhook form from /sources to /hooks and /hooks/new; the event log from .../logs to /hook/ID/events; entrypoint URLs, the ones senders post to, from /webhook/UUID to /h/UUID. The old paths are simply gone, per the owner's ruling. Every link, redirect, form action, test, comment and README mention follows; every link to the event log, and its title and heading, read "Full Event Log".

Keeping the UUID out of logs, metrics labels and error reports, and the receiver rate limits, key on the route itself, so they cover /h/ unchanged. Routed tests follow every link and form the pages render to a moved page.

check / check (push) Successful in 3m23s
Details 
script/test now runs go test without -v. The Docker build cuts each step's log at 2 MiB, and the verbose output of the whole suite passed that limit before any failure was printed, so a red script/cibuild showed only passing packages. Without -v, go test prints one result line per package and, for a package that fails, everything its tests wrote, the application's log lines included. -race, -p 4 -parallel 8 and the 90-second per-package timeout are unchanged.

The cause of the red builds was fixed by the cheaper test hashing already on next; the same two changes go to main separately.

clawbot bfdbc937c6 Keep make test under 2 GB of memory (closes #344)
check / check (push) Successful in 3m41s
Details 
Every test that starts a database seeds the admin account, hashing its password with Argon2id at 64 MB, about 150 MB under -race, and internal/handlers and internal/database ran dozens of those at once. That was the memory, and most of internal/handlers' run time; the product code does not leak.

HashPassword now hashes at a 1 MB cost only when testing.Testing() reports a test binary, so every test package gets it with nothing to add and a binary built by go build always hashes at the shipped parameters. TestHashPassword_ShippedParameters still hashes and verifies through HashPassword at the shipped cost. script/test adds -p 4 -parallel 8.

check / check (push) Successful in 4m43s
Details 
Unset or empty, TRUSTED_PROXIES now defaults to 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16, so a reverse proxy reaching webhooker from one of those ranges gets per-client rate-limit buckets with nothing set. A set value replaces the default entirely; an unparseable one still fails startup. The startup warning for an empty list is gone.

The README gives the default, one rule (if any client can reach webhooker, or the proxy in front of it, from an RFC 1918 source address, set the list to the proxy's address alone), and where to find that address: the remoteIP field of the http request log line. Loopback is not in the default.

That is the same material as the rule above alwaysBlockedNetworks, so a future candidate can be accepted or refused against one rule.

clawbot 1ac4fe0be4 Show 50 recent events with size, processing time and status (closes #347)
check / check (push) Successful in 4m32s
Details 
The webhook page's list, now headed "50 Most Recent Events", shows the 50 newest events, limited in the query. Each row adds the time received (relative, UTC on hover), the body size, the processing time (slowest delivery, queued to final outcome, retries included, "in progress" while pending), and, when the webhook has exactly one HTTP target, that target's latest HTTP status, coloured by class.

Each event now records its body size in a new body_bytes column when it is stored, so the list never reads bodies; the list loads only the delivery and attempt columns it shows, and a failed load is an error, not an empty list.

An existing event database must be recreated: the column is added in place, with no migration.

One caveat on reading a green check: a docs-only commit deliberately
replays from the layer cache

such a commit evidences a replay rather than an executed run. A code
