clawbot ff0018cf43 Add a statistics pane to the webhook page (closes #368)
check / check (push) Failing after 2m53s
Details 
Each webhook's event database keeps running totals: one row for its
events, and one row per target for that target's deliveries, delivered
and failed, each with what retention removed. Every write to them
shares the transaction of the rows it counts. Deliveries get a
finished_at column; it and target_id end the status index, so each
target's deliveries finished in a window come from one index-range
query grouped by target. Retention deletes 1000 expired events per
transaction. The pane is its own template, its figures in tables.

The schema changes in place with nothing back-filled, so an existing
database must be recreated.

proxy, and to nothing wider. A set but unparseable value aborts

If any client can reach webhooker, or the proxy in front of it, from an
RFC 1918 source address (directly, or through anything that can
rewrite source addresses, such as NAT or a published container port),
set `TRUSTED_PROXIES` to the proxy's address alone, or every rate
limit, the webhook receiver's included, can be bypassed by those
clients. The address to set is the `remoteIP` field of the
`http request` log line for a request that came through the proxy.
Behind a proxy the list does not cover, every request keys on the
proxy's own address and all clients share a single bucket per limit.
The receiver limits become service-wide ceilings, and the login
endpoint's failure counting collapses onto one key, so a stranger's
wrong passwords throttle every other client's wrong passwords. Set
`TRUSTED_PROXIES` to that proxy's address to restore per-client
buckets.
That default is safe against forged headers, but leaving it unset in
production has a cost you must know about. Production runs behind a
TLS-terminating reverse proxy, so with `TRUSTED_PROXIES` unset every
request keys on the proxy's own address and all clients share a single
bucket per limit. The receiver limits become service-wide ceilings,
and the login endpoint's failure counting collapses onto one key, so a
stranger's wrong passwords throttle every other client's wrong
passwords.
What it cannot do is lock the operator out. The login endpoint
verifies credentials **before** it consults any limit and charges only
failures, so a correct password is never throttled no matter how full
the bucket is. See [Rate Limiting](#rate-limiting).
The remedy is to set `TRUSTED_PROXIES` to your reverse proxy's
address, which restores per-client buckets. webhooker logs a warning
at startup whenever `TRUSTED_PROXIES` is empty, in every environment,
because behind a proxy every client shares one bucket in `dev` and
`prod` alike. The warning is informational when nothing proxies to the
process: with no proxy in front, the peer address is the client's own
and the buckets are already per-client. See

long-term archiving, separate from the per-webhook event database (which
may prune events under its own retention). Delivering to a database
target writes the full event — body, headers, method, content type, and
webhook/entrypoint/event identifiers — as a row into the target's own
archive database, `archive-{webhook_name}-{target_name}-{target_uuid}.db`,
stored under the data directory beside the event database. Each
`database` target has its own archive file, even when one webhook has
several.
Both names are made safe for a file name the same way: lowercased, ASCII
letters and digits kept, every other run of characters turned into a
single `-`, no `-` at either end, cut to 40 characters, and `unnamed`
when nothing is left. The target UUID keeps the file name unique. A
webhook named `Orders (EU)` with a target named `Long-term archive`
archives into `archive-orders-eu-long-term-archive-{target_uuid}.db`.
Renaming the webhook or the target renames the file, under the same
lock the archive writes and the archive sweeper take, so 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.
The file is moved just before the new name is saved. If the process
stops between the two, the archive is left under the new name while the
UI still shows the old one, and the next delivery starts a second
archive under the name shown. To bring them back together, stop the
service before moving anything, and move each archive as its `.db`
together with any `-wal` and `-shm` beside it, since the `-wal` can hold
rows that are not yet in the `.db`. If no file has the name shown, move
the archive under the new name back to it. If a second archive already
has the name shown, move the archive under the new name out of the data
directory instead and keep it as you would any archive moved away. Then

webhook with different expiries keep two archives, each pruned on its

Note that a webhook has one archive file but may carry more than one
`database` target, each with its own `expiry`. The shortest expiry
configured on any of them therefore governs the whole archive, and the
sweep applies it whether or not the webhook is still receiving events.
Configure a single `database` target per webhook unless you intend that.

proxy, the aggregate limit becomes a service-wide ceiling of 1200
requests per minute across all senders and all entrypoints, where the

and all entrypoints, where the per-entrypoint limit's capacity still
grows with the number of entrypoints. Any deployment with more than a
handful of busy entrypoints must set `TRUSTED_PROXIES`.
