clawbot 74a96b2226 Lint static/js/ with ESLint in Docker (closes #120)
check / check (push) Waiting to run
Details 
`REPO_POLICIES.md` binds the repo to a JavaScript styleguide, but nothing checked `static/js/`. ESLint, pinned by `package.json` and `yarn.lock`, now lints it with the styleguide's two checkable rules, `no-var` and `prefer-const`. It runs only in Docker on a digest-pinned node image: a `js-deps` stage installs ESLint and stays cached until the manifests change, and a `js-lint` stage runs it. `script/lint` builds `js-lint`, so `make lint` and `make check` fail on a violation, and the image build depends on it as on the repo's other checks. ESLint, node and yarn are not prerequisites, and `make lint` never uses a host copy.

clawbot 8b617efa63 Rotate a database target's archive monthly, daily or hourly (closes #379)
check / check (push) Waiting to run
Details 
A database target's rotation setting (none, monthly, daily or hourly) puts the UTC period of each event's receive time in its archive file name, so each file holds exactly its period's events. It is on the new webhook page and both target forms, and shown in the target list. Renames move every one of a target's files and move them all back if one fails. The sweep prunes one file at a time under the target's lock and deletes a rotated file it leaves empty. Download opens one file at a time, oldest period first, finding each again under the target's current name. The target list names the current file and totals all of them.

clawbot d8c60c9b67 Event log: show attempt and delivery times, label replays, zone event times (closes #386)
check / check (push) Waiting to run
Details 
In the event log and on an event's page, attempts and deliveries showed no time, event times had no zone, and a replay looked like the original it repeated. Each attempt now shows when its result was recorded and each delivery when it was created, as how long ago with the full UTC time on hover, and the event log's event times read the same way. A delivery created by Replay records it in a new `replay` column and is labelled a replay in the event's summary line and its delivery list; replays made before this change are not labelled. A delivery's row is now drawn by one template, `delivery_row`, that both pages share.

clawbot ea8384f4a2 Event log: only the newest event expanded, and only the 50 most recent (closes #349)
check / check (push) Waiting to run
Details 
The event log now loads only the 50 newest events, limited in its query, and only the newest starts expanded; the rest start collapsed. Paging is removed rather than capped, since 50 events never need a second page: the Previous and Next links, the `page` query parameter and the page number Replay and Resubmit carried back are gone, and a `?page=` left in an old link shows the 50 newest. A webhook with more than 50 events reads "50 most recent of N events" beside the heading. Comments and a README line that called `page` the only query parameter the service reads now name `next` and `notice`.

clawbot 17e6c85dd8 Name the item and what is lost in each delete prompt (closes #400)
check / check (push) Waiting to run
Details 
The three delete prompts on the webhook page were generic ("Delete this target?") and named nothing. Each now names the item and says what is lost: for a webhook, its stored events, with their number (the figure the statistics pane shows), and their deliveries, while any archive files it wrote are kept; for an entrypoint, that senders using its URL get an error from now on and the URL cannot be restored; for a target, that nothing more is delivered to it while its past deliveries stay in the event log. They stay the browser's own prompts, and a name's quotes, backslashes, newlines or a closing script tag reach the prompt escaped.

clawbot bcdd4791ec Say what a database or log target's attempt did, without a status (closes #388)
check / check (push) Waiting to run
Details 
In the event log and on an event's page, every attempt by a `database` or `log` target read "success  Status: — (no response)". Those targets make no HTTP request, so there is no response to have, and "no response" reads like a failed connection, which is what it means for an `http` target. A successful `database` attempt now reads "archived" and a successful `log` attempt "written to the log", with no status shown; a failed one keeps "failure" and its error line, also with no status. `http` and `slack` attempts are unchanged. The change is in the one shared attempt template.

clawbot f1da5e73dd Event log: an event's ID can be selected without toggling it (closes #348)
check / check (push) Waiting to run
Details 
An event's row in the event log was a button element, whose text a browser will not let be selected, so an event's ID could not be copied. The row now has the button role instead: focusable, toggled by Enter and Space, with `aria-expanded` giving its state. A click on its text toggles the event after 500 ms, the usual double-click interval; the second press of a double- or triple-click cancels that, so selecting the ID leaves the event as it was. A drag over text does not toggle, and a click on the caret toggles at once. The browser test clicks as a person does, so toggling on the first click fails it.

clawbot d2ecb83923 Offer no Replay for a delivery to a deleted target (closes #387)
check / check (push) Waiting to run
Details 
In the event log, a delivery to a deleted target still offered Replay, and pressing it answered "Recreate the target, then replay", advice that cannot work: a recreated target is a new one, and the old delivery still names the deleted one. Such a delivery now has no Replay button, and its row still names the target marked "(deleted)". The refusal, which a page loaded before the delete can still reach, now tells the operator to use Resubmit to send the event to the webhook's currently active targets.

clawbot 643077021d Show a target paused by its circuit breaker (closes #385)
check / check (push) Waiting to run
Details 
A target whose circuit breaker had tripped still showed as Active, and its deliveries sat at a bare "retrying" with no attempts. Its row on the webhook page now says deliveries are paused after repeated failures and until when the cooldown ends, adding that one waiting delivery is then sent to test the target; while half-open it says deliveries are held while one tests it, with no time. Waiting deliveries show "next try no earlier than" the later of the cooldown and their own backoff, with the date when not today. The engine gains one read of a breaker's state and remaining cooldown under one lock, and shares the backoff formula.

clawbot 22fa502638 Remove an http target's max_queue_size (closes #477)
check / check (push) Waiting to run
Details 
An http target's max_queue_size was stored and shown in the target list as "Max Queue Size", but nothing in the delivery engine read it, so an operator who set it expecting deliveries to be bounded got nothing. It is removed from the target, the target list and the README's target table; neither form had a field for it. Nothing checks for a leftover value. An existing database keeps its old column, which is no longer read.

check / check (push) Waiting to run
Details 
Every browser tab read "Webhooker": parsePageTemplate parsed each page before htmlheader.html, whose {{block "title"}} fallback then redefined the page's {{define "title"}}. The page file is now parsed last, so its title replaces the fallback (a later definition of a template name replaces an earlier one, and an empty one never does). A test renders every page template and checks its browser tab title.

clawbot 3489d6909a Offer archive expiry choices on the target forms, show plain units (closes #396)
check / check (push) Waiting to run
Details 
A database target's archive expiry was typed by hand as never or a raw duration such as 720h, and the target list showed it back raw. Adding or editing a database target now offers the new-webhook page's list of choices (never, 1h, 12h, 24h, 30d, 90d, 365d), defined once and shared by all three forms. The edit form starts on the stored expiry, or on the submitted one after a refused save; a stored value outside the choices is listed under its own value, so saving unchanged keeps it. The target list shows the expiry in plain units: "30 days", "12 hours", "never".

clawbot f282c6363d Keep what was typed when a target or webhook edit is refused (closes #381)
check / check (push) Waiting to run
Details 
A refused save on the target edit page answered with a bare text page, losing the form and everything typed, and the webhook edit page came back with the stored values instead of the submitted ones. A refused target edit now shows the edit form again with the reason above it and every value submitted, with the same status codes as before; a refused webhook edit keeps the submitted name, description and retention. Target edits use the same validation as new targets, with no second copy; an encoding or database failure stays a logged 500. The browser test covers a refused save on both pages, and its main function is now a plain list of checks.

clawbot 61371d388e Pin tailwindcss and check the committed stylesheet against it (closes #231)
check / check (push) Waiting to run
Details 
make css ran whatever tailwindcss binary was on the host's PATH, so the committed stylesheet depended on the machine that built it, and nothing noticed when a template used a class the stylesheet lacked. make css now runs the standalone tailwindcss v4.2.1, pinned by sha256, in a Dockerfile stage, and a check stage, run by make check and required by the image build, fails when the committed static/css/tailwind.css differs from what the templates need, showing the differing rules. input.css names its sources. The unused .btn-text is removed and the stylesheet regenerated, dropping only unused rules. The README has a Stylesheet section.

clawbot 19a6705c63 New-webhook page: optional HTTP target URL and archive with pruning (closes #373)
check / check (push) Waiting to run
Details 
The new-webhook page gains an optional HTTP target URL, which creates an http target named HTTP, and an archive checkbox whose pruning choice (never, 1h, 12h, 24h, 30d, 90d, 365d) creates a database target named Archive with that expiry. Both are validated by the add target form's own validation, and the webhook, its entrypoint and its targets are created in one transaction or not at all. A refused form comes back with the reason and every value entered, retention included. The targets can be renamed on the webhook page like any other.

clawbot 93911f28f9 Show a slack target's retry setting in the target list (closes #395)
check / check (push) Waiting to run
Details 
A slack target's edit page offers Max Retries and the delivery engine honours it, but the target list showed only its masked webhook URL, so setting retries changed nothing visible. The list now shows a slack target's Max Retries line exactly as an http target's, from the one function both use, so the label and the "0 (fire-and-forget)" wording cannot drift apart. The Max Queue Size line stays on http targets only. Tests cover a slack target with retries set, and one with a queue size stored that shows no queue-size line.

check / check (push) Waiting to run
Details 
The target list showed nothing about how a target's deliveries were going. Each target now shows Delivered and Failed, each in total and in the last 24 hours. The totals are the per-target running totals kept for the statistics pane, so retention does not reduce them; the 24-hour figures are one count over the deliveries' final-status index, for all of the webhook's targets at once. Pending and retrying deliveries count in neither. If the event database cannot be read, each row says so instead of showing zeros. The archive details and Download button on database targets are kept.

clawbot ff24638ba4 Show each entrypoint's last event and event count on the webhook page (closes #393)
check / check (push) Waiting to run
Details 
The entrypoint list showed no sign of whether anything uses an entrypoint, so an operator with several could not tell which senders are live before deactivating or deleting one. Each entrypoint now shows when its last event arrived, relative with the UTC time on hover, or "never", and how many events arrived through it within the webhook's retention. The last-event time comes from a new entrypoint_totals row written in the transaction that stores the event and left by retention, so a sender quieter than the retention period does not read "never". The count is one grouped query over a new index. Resubmitted copies count in neither. Pre-1.0: schema changed in place.

clawbot da75950e91 Targets section: one Add, then a target type and Next, then that type's fields (closes #370)
check / check (push) Waiting to run
Details 
The targets section of the webhook page showed its add form open with every field, a URL included for types that use none. It now lists only its targets until "+ Add" is clicked; "+ Add" shows a choice of target type with Next and Cancel on one row, and Next shows the name and only that type's fields. The database and log types show no URL field and the server stores none for them; the slack form gains its retry field. A refused target brings the page back with the form open on its type, the values entered and the reason, and Cancel empties it. An encoding failure stays a logged 500. Target validation returns its message, so the new-webhook page can reuse it.

check / check (push) Waiting to run
Details 
Each event now has its own page at /hook/ID/events/EVENTID, behind the login, showing its details, its whole body and every delivery; a resubmitted copy links to its original's page. The recent events on the webhook page link there and expand to show their bodies, only the newest expanded on load. One renderer and one template show a body the same way in the recent events, the event log and the event's page: whole up to 32 KiB, cut there in the two lists with links to the event's page and the download; JSON pretty-printed unless that would grow it past four times plus 1 KiB; over 200 lines in a scrolling box; a body holding NUL or control characters treated as binary and never dumped raw.

clawbot faf7ca1a5e Report or refuse each unusable file webhooker reads (closes #290)
check / check (push) Waiting to run
Details 
An audit of every file webhooker reads configuration or required state from found cases that carried on silently. A zero-length webhooker.db, and a missing or zero-length per-webhook database, now log the "created a new, empty database" warning naming the file; restart recovery opens every live webhook's database, checking under the manager's lock that it still exists, so a missing one is reported at start. The main database's open errors name webhooker.db, for the server and webhooker resetpw; resetpw refuses a zero-length webhooker.db. A directory in place of any database file or its -wal or -shm is refused naming it. The README says how each case is treated. Also closes #459.

clawbot 0f5f6ba6bf Let an entrypoint's description be edited in place (closes #392)
check / check (push) Waiting to run
Details 
An entrypoint's description was set when it was added and could never change, so renaming one meant deleting it and adding a new one with a new URL every sender had to be given again. Each entrypoint on the webhook page now has an Edit button, in the shared secondary style, that opens its description in place with Save and Cancel and keeps its URL. The save goes through the same login, CSRF and ownership checks as the other entrypoint actions; an empty description shows as "Entrypoint". Activate and deactivate now write only the active column, so they cannot undo an edit. Tests cover each, through the router and the browser.

clawbot 820d9391ff Index the event log's resubmit count with deleted_at (closes #325)
check / check (push) Waiting to run
Details 
The event log's resubmit count, run on every page load over up to 25 event ids, read every live event in the webhook's database: GORM adds deleted_at IS NULL, and SQLite, keeping no statistics there, chose the deleted_at index over the resubmitted_from_id one. deleted_at is now the second column of idx_events_resubmitted_from_id, so the count is answered from that index for a whole page of events. A test checks SQLite's plan for the statement as GORM builds it, with a full page of ids. The README's event-tier indexes table lists the index. Pre-1.0: the index changes in the schema in place, with nothing for older databases.

check / check (push) Waiting to run
Details 
For a database target, the target list showed only its expiry, so the archive file the README's backup and move-away advice depend on could only be found from a shell on the host. Each database target now shows its archive file's name, its size on disk (the file and its -wal together) and when it was last written, relative with the full UTC time on hover, all from the files' metadata without opening the archive. Before the first write, and after the file has been moved away, it shows the name and "not created yet". Tests cover all three states.

clawbot 35d2f28c67 Name each embedded static file so a missing Alpine.js fails the build (closes #166)
check / check (push) Waiting to run
Details 
static/static.go embedded the css and js directories, so a build without the extracted Alpine.js file compiled and produced a binary whose admin pages silently had no Alpine. It now names the four files the pages load, so such a build fails naming js/alpine.min.js; make build extracts the file first, so the failure shows when that step is skipped. Both lint stages extract Alpine.js before linting, since the static package no longer compiles without it, and the README's lint stage says so. static/css/input.css, the Tailwind source no page loads, is no longer embedded or served.

clawbot 9526e961b5 Add a Download button that exports a database target's archive as gzipped JSON (closes #374)
check / check (push) Waiting to run
Details 
Each database target on the webhook page has a Download button that streams its archive as gzipped JSON, archive-WEBHOOKNAME-TARGETNAME-TIME.json.gz, with names made safe by delivery.ArchiveFileName's function. The export reads one consistent snapshot through one cursor in a read-only transaction, so archive writes carry on, and holds the rename lock only while it reads the stored names and opens the file. It extends its write deadline as it writes, so a large archive downloads for as long as the client reads; a failure after the response has started aborts the connection so the browser marks the download failed. The request limit is now the service's own middleware, which no longer writes a 504 over a response already started.

Details 
Six test-only gorm.Open calls in internal/delivery passed a bare gorm.Config, leaving the unfiltered idiom in the tree to be copied into production code, where every gorm.Open goes through gormlog.New. They now pass gormlog.New over a logger that discards, so no gorm.Open in the tree uses a bare gorm.Config. The stale sentence saying the tree has one test-only (*gorm.DB).Scan caller is corrected in the README and in the ParamsFilter comment: only tests call Scan, and what a test binds is fixture data.

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.

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.

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.

check / check (push) Successful in 3m18s
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.

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.

check / check (push) Successful in 3m20s
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.

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) Successful in 3m16s
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.

check / check (push) Successful in 3m24s
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) Successful in 3m18s
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) Successful in 3m24s
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) Successful in 3m17s
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) Successful in 3m14s
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) Successful in 3m25s
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.

check / check (push) Successful in 3m17s
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) Successful in 3m34s
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) Successful in 3m18s
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.

created (and lazily on first access for webhooks that predate this
feature). They are managed by the `WebhookDBManager` component, which

A per-webhook database that is missing or zero-length later means its
webhook's events and pending deliveries are gone. The next time it is
opened, an empty one is created in its place, so the webhook keeps
receiving, and `created a new, empty database` is logged at `WARN` with

starts, so this appears at the latest at the first start after the

Renaming the webhook or the target renames the file, under the same
lock the archive writes and the archive sweeper take. Webhook edits,
target edits and target creation run one at a time, so no edit can
rename the file between another's rename and save, and the name on disk
matches the UI. A rename never replaces a file: if one already has
the new name, the edit is refused with an error naming that file, and
the stored name stays. If the archive is not there (the operator moved
it away), the rename is not an error, and the next write creates the
file under the new name.
An optional `rotation` in the target's config JSON (e.g.
`{"rotation":"daily"}`) is `none`, the default, which keeps the one
file, or `monthly`, `daily` or `hourly`. A target that rotates writes
each event to a file named for the period of the event's receive time,
in UTC, put before the `.db`:
`archive-orders-eu-long-term-archive-{target_uuid}-2026-10.db` monthly,

exactly its period's events, and the first event of a new period starts
the next file, so a finished period's file can be moved away like any
archive. A changed rotation applies from the next event: the files
already written keep their names and stay, pruned, shown and downloaded
with the rest, since every file named for the target is its archive,

the move-the-file-away workflow keeps working. Archives with no expiry,
or the expiry `never`, are not touched by the sweep at all.
For a target with several files, the write path prunes only the file it
writes to, and the sweep prunes every one of them, taking the target's
lock for one file at a time, so a write to the target waits for at most
one file's prune. A file that is gone by the time the sweep reaches it
is skipped. A file named for a period that the sweep leaves empty is
deleted, with any `-wal` and `-shm` beside it; the file without a period
is kept even when empty, as it always has been.
Because each `database` target has its own archive file, a target's
`expiry` governs only its own archive. Two `database` targets on one
webhook with different expiries keep two archives, each pruned on its
own schedule.
The webhook page shows, for each `database` target, the name of the
archive file an event received now would go to, the size on disk of all
the target's archive files together, how many there are when there is
more than one, and when the latest of them was last written. The size
counts each `.db` and its `-wal` together, and the last write is the
latest of their modification times, since a write lands in the `-wal`
first. All are read from the files' metadata; the archive is never
opened. While the named file does not exist — before the first write,
before the first event of a new period, and after the file has been
moved away — the page shows `not created yet` beside the name.
Each `database` target on the webhook page has a **Download** button,
which returns its archive as one gzipped JSON file,
`archive-{webhook_name}-{target_name}-{YYYYMMDDTHHMMSSZ}.json.gz`, the
names made safe as above and the time in UTC. The file holds one
object: `webhook` and `target`, each an `id` and a `name`;
`exported_at`; and `archived_events`, one object per archived row with
every column, keyed by column name. The rows come from every one of the
target's files: the file without a period first, then the others in
the order of their periods, oldest first, and each row from a file named
for a period has that `period` beside its columns. A body that is not
valid UTF-8 is written in base64, with `"body_encoding": "base64"`
beside it. An archive that does not exist yet, or was moved away,
downloads with an empty `archived_events`; the download never creates a
file.
The download streams: each row is read and written out compressed
before the next is read, so neither the archive nor the JSON is held in
memory. When it starts it lists the target's files by the stored names,
under the lock that webhook edits, target edits and target creation
hold, and lets go. It then opens one file at a time, only when its rows
are about to be written out, and closes it before it opens the next, so
it never has more than one of the target's files open. To open each, it
takes the lock again just long enough to find the file by its period
under the names stored then, so a rename during the download loses no
file; a file that is gone by then, emptied by the sweep or moved away,
