sneak 1ac8102243 Let an entrypoint's description be edited in place (closes #392)
check / check (push) Waiting to run
Details 
Each entrypoint on the webhook page has an Edit button that shows its
description as a form, with Save and Cancel, in place. Edit hides while
the form is open, so the form always opens on the saved description.
Saving posts to /hook/{id}/entrypoints/{entrypointID}/edit, behind the
same login, CSRF and ownership checks as activate, deactivate and
delete, and writes only the description column, so the URL never
changes. An empty description shows as "Entrypoint". Activate and
deactivate now write only the active column, so they cannot write back
an older description over an edit.

clawbot 0945831442 Clamp the HTTP drain by the tail-hook reserve (closes #170)
check / check (push) Waiting to run
Details 
The HTTP drain at shutdown waited up to ShutdownTimeout regardless of how much of the stop budget earlier hooks had used, so a slow archive sweeper or retention reaper could eat the reserve the hooks after the server need, and the database close was skipped. The drain now waits at most the shorter of ShutdownTimeout and what is left of the budget less TailHookReserve, as the Sentry flush already does. The reserve is documented as derived from the two timeouts. Tests cover earlier hooks having spent part of the budget, on a clock that host speed cannot move, and pin that a drain on the full budget gets all of ShutdownTimeout.

clawbot f82b730c31 Pin the HTTP target's unpinned error checks (closes #285)
check / check (push) Waiting to run
Details 
Seven error checks in internal/delivery/target_http.go could be removed without any test noticing, among them withRetry's check on writing the delivery result, the branch that leaves a sent delivery retrying and recoverable when its bookkeeping write fails. Each now fails a test when removed. The "send succeeded" case starts from a tripped circuit breaker, so a probe whose send succeeds but whose result write fails must still close the breaker. The checks in remainingBackoff and backoffElapsed stay unpinned: removing them gives the same answer, and they state a rule a reader needs. Test change only.

clawbot 1a1fee0874 Name the reaper's hard delete in the event body comments (closes #455)
check / check (push) Waiting to run
Details 
The comments on eventBodyQuery and on TestHandleEventBodyDownload_ReapedEvent404s credited the soft-delete predicate for refusing a reaped event. The retention reaper deletes event rows outright and nothing soft-deletes an event, so a reaped event is simply gone. Both comments now say so; the test's "soft deleted" case is described as pinning the query's deleted_at predicate for a row no code produces today. Comments only.

clawbot 290925f184 Fix two resubmit comments and test the resubmit route's middleware (closes #252)
check / check (push) Waiting to run
Details 
Two comments named the wrong mechanism: loadResubmitSource credited soft-delete for refusing a reaped event, though the retention reaper deletes event rows outright, and createAndFanOut claimed to be the only path that creates deliveries, though per-delivery replay creates one without an event. Both now say what the code does. The resubmit route's middleware had no tests through the router; new tests drive the production router to pin the refusal without a valid CSRF token, the rate limit, signed-out requests never spending it, and another webhook's event refused by the event lookup while the user's own event is accepted. Each fails with its check removed.

clawbot 73353bc8e5 Harden the (*gorm.DB).Scan guard test (closes #232)
check / check (push) Waiting to run
Details 
The test that refuses production calls to (*gorm.DB).Scan, the one GORM path that bypasses the logger's value suppression, overstated what it checks and could pass while skipping a whole package. Its comments now say it matches receiver method names, not types, and name the evasion this leaves; GORM's Rows is dropped from the accepted names. Method values are stated as out of scope with the reason. The file-count floor is replaced by a check that every package the walk parses, static and templates included, was reached. The planted snippets are valid Go and cover each receiver form the guard claims to handle. Test change only.

clawbot 40f59ec4d2 Try every event database file on delete and say which was left (closes #275)
check / check (push) Waiting to run
Details 
DeleteDB returned on the first event database file it failed to remove, so with WAL sidecars present a failure could be reported as "the file was left behind" after the events themselves were already gone. It now tries the database file and both sidecars, and its error says which case happened and names each file left: the database file is still on disk, or it is gone (the events are lost) and only a -wal or -shm sidecar remains. The webhook delete handler logs a different message for each and never says the events survive when they do not. Tests cover a normal delete with both sidecars, and a failed removal of the database file or a sidecar, through DeleteDB and the handler.

clawbot 806c95e305 Make every clickable control look clickable, in two shared styles (closes #375)
check / check (push) Waiting to run
Details 
Many controls were plain coloured text with no sign they could be clicked: Edit, Activate, Deactivate, Delete, Replay, Resubmit, both Add controls and the copy control beside each entrypoint URL. Every clickable control is now a real button or link in one of two shared styles: the buttons in input.css, now with a pointer cursor, and btn-small, a small bordered secondary action in style.css, which the layout now loads. The site name, the footer links and each webhook list card show at rest that they open something, with focus states. The copy control shows "Copied" after a click. Rows on the webhook page and in the event log wrap at phone width. The browser test covers the copy control.

clawbot 45bd7e9b94 Pin the close before the reopen in the archive sweep (closes #103)
check / check (push) Waiting to run
Details 
The archive sweep closes a target's archive connection before it reopens the file, and no test noticed if that close was removed, which would leak one SQLite connection per target per sweep. A test now keeps the connection from before a sweep that reopens the archive and requires it closed afterwards. The sweeper's query for database targets takes the sweep's context; a sweep whose context is done returns without an error line, so stopping is not logged as a failure, and a test pins that. The comment on the sweeper's cancel function gives the true reason it needs no lock: fx calls the stop hook only after the start hook has returned.

clawbot bf3df0312b Clear the environment in the cmd/webhooker tests that build a Config (closes #452)
check / check (push) Waiting to run
Details 
The two cmd/webhooker tests that build the app graph, TestNewApp_StopTimeout and TestNewApp_SendsFxEventsToTheLogger, built a Config without clearing the environment, so a variable exported in the developer's shell changed their result: a METRICS_USERNAME without METRICS_PASSWORD failed the second. Both now call config.ClearEnvForTest before setting their own variables, as the config tests and the first-boot test already do. No other test outside internal/config builds a Config through config.New. Test change only.

clawbot 503c57efd9 Assert the body a retry delivers, not only its status (closes #294)
check / check (push) Waiting to run
Details 
TestProcessRetryTask_LargeBody_FetchFromDB and TestProcessRetryTask_SuccessfulRetry checked only that the delivery ended delivered, so deleting the event-body fetch on the retry path, the behaviour the first is named for, left both green while a retry could deliver an empty or truncated body. Both now compare the body the target received with the stored event body byte for byte, and both fail when that fetch is deleted. The other retry-path tests are not about the body and are unchanged. Test change only.

clawbot d084f4f912 Pin the body cap's order in every page route group (closes #93)
check / check (push) Waiting to run
Details 
Follow-ups from an August review of the body cap, each checked against the current tree. One route test now requires an oversized POST, with no session and no CSRF token, to be refused with 413 before CSRF runs, in every page route group with a POST route and in /settings/, so moving a group's body cap after CSRF fails it. The three test router helpers build the server through New with a lifecycle that is never started, so no field is set by hand. The middleware test comment names runMaxBodySize, and the MaxBodySize doc comment says methods other than POST, PUT and PATCH pass uncapped on purpose. The README item was already settled.

clawbot e67fffb05d Check the log charge against every code point (closes #172)
check / check (push) Waiting to run
Details 
The access log's 2,560-byte line ceiling holds only if logfield.EncodedBytes charges each code point at least what the log handlers write for it, and the test checked that on a sample. TestEncodedBytes_ChargesAtLeastWhatTheHandlersEmit now covers every code point, surrogates aside, for both handlers. Below U+1000, where the handlers' escaping varies, each code point is measured alone, both in a bare value and in a quoted one, so undercharging any of them, DEL included, fails and names it. From U+1000 up it compares batch sums, which the doc comment says can hide one JSON-only overcharge. Reverting the astral charge to 6 fails the test. It adds under 2 seconds under -race.

clawbot 4958a6f2e4 Isolate config tests from the shell; any out-of-range PORT is ErrInvalidPort (closes #94)
check / check (push) Waiting to run
Details 
The config tests unset variables without restoring them and read whatever the developer's shell exported, so results could differ from one machine to the next. config.ClearEnvForTest, in internal/config/testing.go, unsets every variable in the process environment and, when the test ends, leaves it exactly as it found it; every config test and the first-boot test call it before setting their own. TestEnvPositiveInt and TestEnvPort share one table runner, and the port errors name the bad value. A PORT of zero, below zero, or too large to parse now matches ErrInvalidPort, as one above 65535 already did. The README and the Settings page say an unparseable or non-positive RETENTION_SWEEP_INTERVAL stops startup.

clawbot 385fbc1a6a Send fx's own events through the service's logger (closes #183)
check / check (push) Waiting to run
Details 
fx printed its dependency graph and lifecycle hooks through its own console logger on standard error, so an operator shipping the JSON log to a collector got a second shape on a second stream for every start. The production app now passes fx.WithLogger with a small FxLogger in internal/logger that writes fx's events through the service's logger: graph events at debug, lifecycle at info, failures at error. Its constructor takes the configuration, so DEBUG=true applies before fx replays the events it held back. go.uber.org/fx moves from v1.20.1 to v1.24.0. Tests keep fx.NopLogger. The README says a failure before the logger exists, and the Go runtime's own output, still go to standard error as plain text.

clawbot c22ca6218e Pin the rate-limit key for an empty RemoteAddr (closes #168)
check / check (push) Waiting to run
Details 
A request whose RemoteAddr is empty has no peer identity, so the rate limiters' key falls back to the raw empty string and every such request shares one bucket: it fails closed rather than giving each its own. net/http always fills RemoteAddr for a TCP listener, so normal serving never reaches this. The behaviour is unchanged and now deliberate: a test pins the shared key, and a one-sentence comment at the fallback tells the empty case apart from a Unix-socket listener, where every peer legitimately carries the same address.

clawbot 0ccb01cada Close the retention follow-ups from the August review (closes #99)
check / check (push) Waiting to run
Details 
Follow-ups from an August review of the retention bounds, each checked against the current tree. A test now pins that a retention value above the keep-forever sentinel is stored as the sentinel. The form's retention parser returns its message directly, so the two error values that were never compared, and the function that mapped them to messages, are gone. The sweep's own keep-forever skip, which duplicated the check in retentionCutoff, is removed; the cutoff is now asked before the webhook's database is opened. The create-form refill test uses HTML-special characters and checks they come back escaped. The README item was already settled; handling for rows made by hand is declined.

clawbot 1f22b30de3 Log the client address next to the peer address (closes #270)
check / check (push) Waiting to run
Details 
Behind a trusted proxy every log line named only the proxy, so abuse could not be traced from webhooker's own logs although the rate limiters already knew the client. The access log, the rate-limit rejection lines, the CSRF warning and the receiver's request line now carry clientIP next to remoteIP. remoteIP still means the connecting peer; clientIP is the address the rate limiters key on, the forwarded client when the peer is inside TRUSTED_PROXIES, worked out once per request by the same code. The README says the field is only as trustworthy as TRUSTED_PROXIES. The access log's 2,560-byte line ceiling holds with the field charged, and a size case with an oversized X-Forwarded-For pins it.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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) Successful in 3m20s
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.

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.

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.

check / check (push) Successful in 3m11s
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.

check / check (push) Successful in 3m16s
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.

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.

check / check (push) Successful in 3m25s
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) Successful in 3m23s
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.

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.

clawbot 7d360babed Logging in returns to the page that was asked for (closes #384)
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.

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.

clawbot 1c721ede41 Run the test suite without -v so a failure shows in the build log (next side of #414)
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)

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.

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.

A provider's other public addresses, such as 161.26.0.0/16 and 166.8.0.0/14, are not refused. Docs and a comment only; the lists are unchanged.

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.

Details 
The build no longer downloads Alpine.js. Its npm package tarball is committed as 3p/alpinejs-3.14.9.tgz, byte for byte the file script/fetch-assets downloaded, with the sha256 that script pinned. script/assets (make assets) extracts package/dist/cdn.min.js to the ignored static/js/alpine.min.js; script/test runs it, so make test, make check, the pre-commit hook and the Dockerfile get the file with no network access, and make build, run and dev run it too.

Usernames are limited to 1024 bytes, so no account can exist that is unable to log in. The username rides in the session cookie, which browsers and securecookie refuse past about 4 KB, leaving room for roughly 2000 bytes of username; the limit is about half that.

User.BeforeSave returns ErrUsernameTooLong when a whole User is created or saved. A byte-counting check constraint on users.username catches every other write, including a column update. The limit appears in the constant and in the struct tag; a test fails if they disagree.

clawbot b79e4649a1 Container sets its data directory's owner and mode itself (#353)
check / check (push) Canceled after 0s
Details 
Closes #340.

The image no longer sets `USER`. Its new `ENTRYPOINT`, `deploy/docker-entrypoint.sh`, starts as root, creates `DATA_DIR` if missing, gives the directory and anything in it owned by another user to `webhooker` (UID 1000), sets the directory to `0750`, and runs the command as `webhooker` through `su-exec`. An empty root-owned bind mount, or data left by another UID, now works as mounted; the app never runs as root and is still PID 1. `CMD` is still `/app/webhooker`, so the `resetpw` commands are unchanged. Started with `--user`, the script only runs the command. It is in `/usr/local/bin`, not `/app`, which belongs to `webhooker`.

README: the UID 1000 ownership block, the upaas pre-deploy commands and the restore ownership step are gone; the upaas volume bullet names only the path.

- Judgement call: `su-exec` over `setpriv`: Alpine's small tool for this, needing only musl; busybox's `setpriv` cannot change user, and util-linux's adds `libcap-ng`.
- Deviation: `su-exec` is pinned by version (`0.2-r3`), not by hash; `ca-certificates` beside it is unpinned.
- Judgement call: each start reads every entry's owner but changes only entries owned by someone else.
- `docker exec` and the health check now run as root, since the image sets no `USER`.
- No automated test covers the script: the suite runs inside `docker build`, which cannot start a container.
- A missing host directory under upaas is sneak/upaas#235.

clawbot 1428154bbd Let a browser with cookies from an earlier database log in (closes #359)
check / check (push) Canceled after 0s
Details 
A new database brings a new session key. A browser still holding the
old session cookie got a 500 on a correct login: Session.Get returned
the cookie's decode error and the login handler answered it with a
500. Get now treats a cookie that does not decode as absent, and
logging in replaces it. gorilla/csrf already did the same for the
CSRF cookie.

A start that creates webhooker.db now logs "created a new, empty
database" at WARN with its path, shortly before the first-boot banner,
so an unexpectedly empty DATA_DIR is noticed.

The codec tests now decode through the store, since Get no longer
reports the codec's reason.

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
