Both tag fields (post and edit) now suggest existing tags as you type,
matching the web upload/manage forms. Suggestions come from a new
GET /api/tags.json that serves the generated public/tags.json. It lives under
/api/ so nginx proxies it to the app, reaching non-browser clients even when a
front-door botwall gates the static site (the same approach as /api/thumb/).
/api/tags.json and /api/thumb/{slug} are both left unguarded: they serve the
same public data as the static site (/tags.json and /thumbs/), so there is
nothing to protect, and keeping them off the auth path means they can never
return 401 — otherwise an nginx auth-fail jail (fail2ban) would ban the app
over an autocomplete poll or a per-row thumbnail load.
A reusable TagField composable filters on the token after the last comma and
completes it on tap; fetchTags() returns an empty list on any failure, so the
field degrades to a plain tags input when the endpoint is absent.
Thumbnails were blank on the manage screen because the app fetched them from
the static /thumbs/ path, which a front-door botwall on `location /` blocks for
a non-browser client even though /api/ (proxied to the app) works. Add an authed
GET /api/thumb/{slug} that serves the thumbnail JPEG from public/thumbs/, and
have the app fetch from there. Also show the thumbnail in the edit dialog, not
just the list rows.
Construct the photo picker with an explicit maxItems so it reliably opens in
multi-select mode; the no-arg PickMultipleVisualMedia default has been seen to
present single-select on some devices.
Add GET /api/session, an unguarded probe that reports whether the request
carries valid credentials. It returns 200 with {"authenticated":bool} and never
sends WWW-Authenticate, so the static public pages can check login state without
triggering the browser's Basic-auth dialog. To keep it from being a
password-guessing oracle that bypasses the /upload limiter, a request with no
credentials is answered cheaply as false, while wrong credentials go through the
same failed-attempt limiter (429 once drained).
static/session.js, loaded by every page template, calls it and, only when
authenticated, builds a fixed toolbar: Upload / Manage links, an "Edit this"
link on photo pages (via <body data-slug>, deep-linking to /manage?edit=<slug>,
which scrolls to and focuses that row), a signed-in indicator, and a log-out
control. Logged-out visitors see nothing and get no dialog.
Log out is best-effort: HTTP Basic has no reliable sign-out (the browser caches
credentials until the window closes), so it overwrites the cached credential and
reloads, which works in some browsers but not all. A dependable logout would
need cookie sessions.
A new auth-gated web UI at /manage lists every post for inline editing of
caption, date and tags, with per-row and bulk delete and bulk tag add/remove.
It is backed by a small JSON API (all behind the same htpasswd Basic auth as
/upload, and unlinked from the public site):
GET /api/photos list posts (newest first)
POST /api/edit rewrite one sidecar (caption, date, tags)
POST /api/tags bulk add/remove tags across posts
POST /api/delete move posts to content/.trash/ (reversible)
GET /api/trash list trashed items
POST /api/restore move a trashed item back (409 on live-slug clash)
POST /api/trash/empty hard delete trashed items (id… or all=1)
Design notes:
- Editing only rewrites the .toml; the slug (and URL) never changes.
- Delete is reversible: image + sidecar move to content/.trash/ with a
timestamp suffix, excluded from the site (loadPhotos skips dirs). The only
hard delete is emptying the trash.
- Build now prunes: it drops the derived HTML trees (photo/ day/ album/ page/
grid/page/) and regenerates them, and pruneRenditions removes orphaned
images/thumbs/medium/og. Without this a deleted post would linger at its old
URL and on stale day/album pages; this also cleans up after a hand-removed
sidecar.
- Sidecars are written atomically (temp + rename) so a concurrent build never
observes a half-written file.
- Slugs and trash ids are validated as bare filenames, closing path traversal
and dotfile access.
- Every state-changing POST passes a sameOrigin (CSRF) check, since Basic-auth
credentials are replayed by the browser on every request to the host. It
honours Sec-Fetch-Site, falls back to Origin vs base-url/Host, and allows
header-less non-browser clients. Ported from the independent /manage on
plex/trunk-ng.
module.nix proxies /manage and /api/ to the app (nginx otherwise serves them
as missing static files). The apps are unchanged; the API is there for them to
adopt edit/delete later.
Add HTTP Basic auth on /upload, reading an Apache htpasswd file (bcrypt
only, `htpasswd -B`) via a new -htpasswd flag. This lets nginx drop to a
plain TLS-terminating reverse proxy with no auth of its own; the existing
bcrypt htpasswd file is reused unchanged.
auth.go:
- LoadHtpasswd parses user:hash lines, keeps bcrypt entries ($2a/$2b/$2y,
so Apache's $2y$ works), skips MD5/SHA/crypt with a warning.
- Unknown users still pay for one bcrypt comparison against a dummy hash,
so response timing can't enumerate valid usernames.
- Failed attempts draw from a token-bucket limiter (x/time/rate, ~1/s,
burst 10) returning 429 once drained; successful and bulk uploads never
touch it.
server.go guards both /upload routes (nil authenticator = passthrough for
local --serve). /health stays open. Empty -htpasswd disables auth and logs
a warning.
module.nix: new top-level services.photogallery.htpasswdFile, delivered to
the service via systemd LoadCredential (so a root-owned 0400 secret works).
Removed nginx.htpasswdFile and basic_auth from the vhost.
Both uploader apps already send Basic credentials, so no client change.
Deps: golang.org/x/crypto/bcrypt, golang.org/x/time/rate (vendorHash bump).
An album is a tag. Photos carry lowercase free-text tags in their .toml
sidecar (`tags = [...]`), parallel to the existing day grouping — no
database, all derived at build time.
- albums.go: parseTags (lowercase/trim/dedupe, slug via sanitiseSlug),
groupByTag mirroring groupByDay, and rendering for album pages, the
index, and the JSON API. Slug collisions between distinct names are
suffixed and logged.
- Routes: /album/<slug>/ (paginated square grid per tag), /albums/ (index
with counts), /tags.json (machine-readable tag list, served statically
like feed.xml).
- POST /upload gains a `tags` field written into the sidecar; the web
upload form gains a tags input.
- Tags shown on each photo page linking to their album; an Albums link in
the timeline/grid header.
