splitsec2 20848a8774 docs: small fixes from a check of the docs against the code (#1567)
These are the leftovers from the docs check, the fixes that did not
belong in the other three.

Claude did the comparison and wrote the changes here too, so I would
still like a human look before it merges. The one new piece of prose
worth a read is `troubleshooting.md`. It was a TODO page that two other
pages link to, so I filled it with only what I could confirm in the
code: where the logs go, `LOG_LEVEL`, the `DEBUG=true` bundle from the
bug report template, and reporting an issue. Happy to drop it back to a
stub if you would rather write that one yourself.

- `configuration.md`, `custom-scripts.md`, `users-and-requests.md`:
Booklore is Grimmory in the UI now. The stored mode value is still
`booklore`, and the custom script doc says so. The hardlink heading now
matches the "Hardlink Book Torrents" and "Hardlink Audiobook Torrents"
checkboxes.
- `custom-scripts.md`: the email output runs scripts too
(`phase=post_email`, `output.mode=email`, details under
`output.details.email`). It was missing from the phase list.
- `users-and-requests.md`: a delivery that fails with no retry available
goes back to pending on its own, and the admin reopen action is for
rejected requests. The page said an admin reopens a failed delivery.
Also noted that rules cannot use Request Book.
- `hardcover-sync.md`: added the missing
`AUTO_DOWNLOAD_AUDIOBOOK_MIN_SIZE_PERCENT` row and a sentence in the
ranking paragraph.
- `api-access.md`: an admin session also reads `/api/stats`, and what
the 403 says.
- `installation.md`: points at the Lite, Tor and WireGuard variants.

Docs only, no code touched.

splitsec2 755f28a6a4 feat(api): add a read-only API key and a /api/stats endpoint (#1419)
This is the read-only API key from #1410, where you said to go ahead.

I run Shelfmark behind Homepage and wanted more on the dashboard tile
than up or down, without putting an admin API key in the dashboard's
config. This adds a second key, `SHELFMARK_API_KEY_READONLY`, that can
read one new endpoint.

`GET /api/stats` returns counts only: books added over the last 7 and 30
days by format, the queue, requests by outcome, and download failures
over the last 7 days. No titles and no user names. The read-only key,
the admin key or an admin session can read it.

The read-only key gets a 403 on every other path and on any write,
including a POST to `/api/stats` itself, and it never gets a session or
a cookie. If a request carries both keys, the admin one wins, so a
proxy's own `Authorization` header can't downgrade a correct
`X-Api-Key`. Unset means off, like the existing key. The endpoint exists
either way, but without a key only an admin session can read it.

It also adds a `db_path` property on `UserDB`, so the stats module can
open the database read-only.

Tests cover the key scope, the 403s for the read-only key, both keys at
once, who can reach the endpoint, and the counters. The full suite
passes, and I broke each rule on purpose to check a test catches it. A
version of this has been running on my own install behind Homepage.

If you'd rather have the stats in a different shape or under a different
path, I'm happy to change it.

CaliBrain d978896142 fix(auth): rename the API_KEY env var to SHELFMARK_API_KEY (#1374) 2026-09-21 00:10:10 -04:00
Gavin McFallandClaude Fable 5.1 3b280009ae feat(auth): static API_KEY (env) accepted as Bearer or X-Api-Key, cookie or key (#1366)
Supersedes #1353, per the discussion in #1352: one `API_KEY` environment
variable; when set, a request carrying it is authenticated as the first
admin, and cookie sessions keep working exactly as before (cookie **or**
key). Nothing else changes. No table, no UI, no settings-tab switch, no
per-user keys.

## What

- `API_KEY` (env). Unset → the feature is off and none of the new code
runs.
- `Authorization: Bearer <key>` or `X-Api-Key: <key>` on any existing
`/api/*` route authenticates that request as the first admin in
`users.db` (`ORDER BY id`), or as a bare admin identity
(`user_id="api"`, `is_admin=True`, no local user row) if the install has
no admin yet. Per request only; nothing is persisted; the admin's role
is read live, so deleting or demoting that user takes effect on the next
request.
- Both headers are checked and either may match. That is what makes the
key usable behind a reverse proxy that injects its own `Authorization`
header (oauth2-proxy, Authelia, forwardAuth): send the key in
`X-Api-Key`.
- A credential that is **not** the key is ignored and the request
continues on the normal session path, so proxy-forwarded tokens are
unaffected. Without a valid session such a request gets the usual `401
{"error": "Unauthorized"}`, identical to a request with no credential,
so there is nothing to probe.

## How

- `shelfmark/config/env.py`: `API_KEY = os.getenv("API_KEY",
"").strip()`.
- `shelfmark/core/api_key.py`: `extract_api_key_candidates()` (Bearer
token if the scheme is Bearer, then `X-Api-Key`) and `matches_api_key()`
using `hmac.compare_digest` on bytes.
- `shelfmark/core/user_db.py`: `UserDB.get_first_admin()`.
- `shelfmark/main.py`: `api_key_auth_middleware` (`before_request`,
registered before `proxy_auth_middleware`, which early-returns for keyed
requests). Only `/api/` paths; `/api/health` and `/api/auth/*` exempt;
no-op when `API_KEY` is unset or the auth mode is `none`. On a match it
mirrors the proxy-auth pattern: `session.clear()` then populate
`user_id` / `is_admin` / `db_user_id` for this request, `permanent =
False`, `modified = False`, `g.api_key_auth = True`. An `after_request`
hook guarantees no `Set-Cookie` is written for a keyed request even if a
handler dirties the session.
- `docs/api-access.md` (new), the `API_KEY` entry in
`docs/environment-variables.md`, and a README link.

## Security

- Constant-time compare; the key is never logged or echoed.
- Keyed requests never mint or refresh a session cookie and ignore any
cookie sent with them (a non-admin cookie plus the key yields admin for
that request; the browser's own session is left untouched and usable).
- The mismatch path touches neither the session nor `g`, so a stray
bearer on a browser request can neither log the user out nor change how
their cookie is refreshed.
- Store errors during the admin lookup fail closed (`500 {"error":
"Authentication error"}`), never to anonymous.
- Verified against Flask's `save_session` / `should_set_cookie`
ordering, and under auth modes `none`, `builtin`, `proxy`.

## Tests

`tests/core/test_api_key_env.py` (36): extraction and matching;
first-admin lookup; middleware behaviour on a guarded route and an admin
route, with and without a user_db, `X-Api-Key`, both-headers
combinations, no `Set-Cookie` when a handler dirties the session,
incoming non-admin cookie ignored, browser cookie still usable after a
keyed request, security headers, store error → 500, mismatch → guard's
401 / cookie path / permanent cookie untouched, unset → off, exempt
paths and path probes, `none` and `proxy` modes, deleted and demoted
first admin, a keyed write passing the guard. Existing auth suites
unchanged. All CI gates green on the fork:
https://github.com/gavinmcfall/shelfmark/pull/2 (CI-only draft).

Also exercised against a running instance: 47 scripted checks including
150 concurrent requests, proxy-mode switching through the key, an
unset-key restart, and a log scan for the key.

## Naming

`API_KEY` as discussed. If you'd rather namespace it
(`SHELFMARK_API_KEY`) to avoid clashing with other tools' env vars in
shared compose files, it is a one-line change; say the word.
