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 small shared widget (static/tagcomplete.js) completes the tag after the last
comma from the existing tag list, keeping earlier tags intact. It is wired to
every comma-separated tag input: the upload form, and the manage page's per-row
edit field and bulk add/remove fields.
Suggestions come from /tags.json, which the generator already writes on every
build and nginx serves statically, so no server change is needed; the list is
fetched once, cached, and invalidated after an edit that may add a tag. Keyboard
navigation (up/down, enter/tab, escape) and click selection are supported.
The /manage page posts with FormData, i.e. multipart/form-data, but the edit,
delete, tags, restore and empty-trash handlers parsed with r.ParseForm, which
only reads urlencoded bodies. So every field came back empty: delete returned
200 with deleted:0 and moved nothing, edits saved nothing — while curl -d
(urlencoded) worked, which is why tests and manual checks missed it.
Parse with ParseMultipartForm (tolerating ErrNotMultipart so urlencoded still
works), via a shared parseForm helper used by all manage handlers. handleUpload
already did this. Also stop the UI reporting deleted:0 / updated:0 as success,
and add a multipart regression test.
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.
