The Rust port creates index_messages_on_room_id_and_created_at on boot,
under the same name and on the same columns, with CREATE INDEX IF NOT
EXISTS. On a database the port opened before this migration ran,
db:prepare stopped with "index ... already exists" and the app didn't
start. With if_not_exists the migration skips an index that is already
there and creates it everywhere else.
Databases that already ran the migration don't run it again, and the
dumped schema is the same, so db/schema.rb doesn't change.

Showing an image's preview when its variant had already been made tied the cached message to state
that changes without touching it: a variant made after the message was cached would never show. It also
cost a query per embedded image, since Action Text loads the embeds without their variant records.
Nothing in the app makes those variants, so the partial no longer looks at them.

Files are posted as a message's own attachment, and the composer puts none in the rich text: it permits
only mentions and link embeds. The server still keeps any attachment whose signed id resolves, a blob
included, and Action Text's blob partial links to a representation URL that makes the preview on the
first request, without the limits the POST has, and on every request while it fails.
The app's own partial shows an image's preview only if it was already made, and otherwise the file's
name and size, as it does for a file that isn't an image. The cached presentation's version goes up,
since Action Text renders the partial by name and the template digest doesn't see it.

ActiveStorage::Preview#processed? is true as soon as ffmpeg's frame is attached, but the poster is a
variant of that frame and can fail on its own: the POST rescues a Vips::Error and leaves the frame
attached. The view then emitted the poster's URL, and every view retried the resize. It now checks the
variant too, from the variant records with_attached_attachment already preloads.

A video's preview and a picture's thumbnail are made inside the request that posts the message, and
nothing bounded how long either could take.
- The video preview filter also selects any frame from 5 seconds on. Rails' filter takes the second
frame it selects, which a video with a single keyframe and no scene change only gives at its end, so
ffmpeg decoded all of it.
- TimeLimitedVideoPreviewer gives ffmpeg 10 seconds of wall-clock time, kills it past that, and reports
a failed preview, so the message is posted without one.
- Pictures and videos above 250 megapixels, or whose size couldn't be read, get no preview: decoding
costs in proportion to the pixels, however small the file.
- The view shows a preview only if it was made when the message was posted. Its URL used to make it on
view, so a preview that failed or was skipped would be attempted again on every view. The cached
presentation's version goes up, so cached messages pick this up.
- A video's poster is made, when the message is posted, at the size the view shows it. The full-size WebP
made until now wasn't shown anywhere, and encoding it costs in proportion to the frame's pixels.

The deadline in Opengraph::Fetch started after the lookup of the pasted
host, and an unfurl looks up more hosts outside any fetch: the canonical
URL's, and the image's, once to check its content type and again to
validate it. Each of those waits as long as the resolver takes to give
up. Move the deadline up to UnfurlLinksController, around everything the
link leads to; Opengraph::Fetch keeps its per-operation timeouts and
makes no retries.

Opengraph::Fetch runs inside POST /unfurl_link, against a host the member
picked, with Net::HTTP's defaults: 60 s to connect, 60 s for each read, and
one retry of the GET. A per-read timeout doesn't bound a host that sends a
byte at a time, in its headers or its body, so nothing limited how long a
fetch could hold the request thread.
Give each operation 7 s, as Webhook does, turn off the retry, and put the
whole fetch, redirects included, under one 10 s deadline.

Rails 8.2 compiles HTML templates through Herb in strict mode, so a
template that doesn't compile fails to render. herb:check boots the app,
which loads ruby-vips, hence libvips.

Rails main (e3d5c569) moves Campfire's pin forward ten months. Because
Campfire loads the 8.2 framework defaults, the ones added since then take
effect too, among them header-only forgery protection, Herb as the HTML
template engine, strict Accept headers and immediate blob analysis.
Changes it needed:
- Minitest 6 has no minitest/unit; the test helper no longer requires it.
- Rack::Sendfile is no longer in the middleware stack; DebugLocks goes
before ActionDispatch::Executor, as the Rails guide now says.
- Time::DATE_FORMATS is deprecated; :epoch is registered through
ActiveSupport::TimeFormats.
- Channel test subscriptions expose stream_names; streams is private.
- sentry-rails declares its Action Cable handle_open and handle_close
wrappers private, which Rails 8.2 calls from outside the connection, so
no /cable connection succeeded. An initializer makes them public until
getsentry/sentry-ruby#2972 ships (issue #2975).
- Lexxy renders editor content through Rails' editor adapter when Rails
has one, which asks a mention for its editor partial. It is the same
users/mention partial the mention prompt already inserts.
- redis-client moves to 0.30.1: Rails main's Redis cache store, which
production uses, requires 0.28.0 or later, and assets:precompile
(the Docker build) aborted on 0.25.2.

(cherry picked from commit b4d3880a3d88059dd5b0b884f1f5f1a6f82aa95c)
Rails main compiles HTML templates through Herb under the 8.2 framework
defaults, which Campfire loads. Herb rejects `case` and its first `when`
in a single ERB tag, so the three pwa/ partials failed to compile, and
`herb:check` rejects ERB output in attribute names, which the account
settings' switch used for `checked`. Give `case` its own tag and build
the switch with tag.input; both render the same under Erubi.

An attachment message is indexed by its file name, and the update
action still accepts a new attachment. Active Storage clears
attachment_changes in its own after_commit, which runs before this one,
so the replacement is noted in before_update.

Pages of messages load them with_presentation, which preloads each
message's boosts with their boosters and avatars, but the boosts partial
asked for message.boosts.ordered: a new query for every message, and the
preloaded boosts went unused. Sort the preloaded boosts in Ruby. The
boosts frame, whose message comes without them, still queries them in
order with their boosters.

Boosting and unboosting touch the message, so after_update_commit
rewrote its row in the full-text index with the same text, loading the
rich text again to rebuild it, on every boost. The index only needs a
new row when the rich text body was saved.

Each push notification carries the subscriber's unread room count as its
badge. The pool built it per subscription, loading the user and counting
their unread memberships: two queries for every subscriber, all in the job
before the deliveries reach the threads. With 1,000 subscribed members the
job spent ~180 ms and 2,000 queries there; with 5,000, a second.
The pool now counts the unread rooms of a whole batch with one grouped query
and hands each subscription its badge; nothing else in the notification needs
the user. The queries still run before the work is posted to the threads,
which run outside the Rails executor. Push::Subscription#notification still
counts by itself when no badge is given, as for the test notification.

Every boost had its own fragment, nested inside the message fragment that
already holds it. With a cold cache, a read and a write per boost plus a
read_multi and a write_multi per message: a room page of 40 messages with
120 boosts takes ~410 ms instead of ~290 ms. Redis runs without persistence
(config/redis.conf), so every page is cold after a restart.
A boost touches its message, so adding or removing one rewrites the message
fragment anyway. The inner fragments only paid off when a message with many
boosts was drawn again, and there they hid a lookup per booster. The boosters
are now loaded with the boosts, one query per message.

The job picks the room's members once and then publishes to them one at a
time, as the request did before it. A member who opens the room during that
loop gets the read event in their other tabs and then the older notice,
which marked the room unread again. Both events now carry the server time,
and the sidebar ignores a notice dated before the room's latest read. The
notice still moves a direct room to the top.
