The grouping landed in the daemon; this is what it looks like. A tile whose shot
was stored as more than one file badges that in the corner — "RAW" when one of
the members is a raw file, since that is the word the person is looking for, and
a plain count otherwise (a live photo, a burst). The lightbox gains a control
that steps through the group's files, which is the only way to reach the RAW now
that the grid shows the shot once.
Deleting says what it will do: the daemon takes the whole group, so the
confirmation names the file count when a selection stands for more files than
tiles.
A camera that writes both puts two files on the volume, and the timeline showed
two tiles of the same photo. They are one shot to the person who took it.
Schema v30 records what ties them together: the server's own duplicate hash and
main-photo relation, plus a `group_key` every member of a shot carries. The key
is computed when the timeline is replaced, in three steps — the server relation
first, because it knows about live photos and bursts and we do not have to guess
at them; then same capture day, same file-name stem and one member raw while the
other is not, which is the pair a camera writes; otherwise the photo is its own
group. The member the grid shows is the non-raw one, since a JPEG decodes in
milliseconds and is what the person expects to see.
The gallery therefore pages by group and carries `group_size` and `has_raw` on
each entry, and the date scrubber counts what the page shows. The Raw tab is the
exception and still lists every raw file, because that tab exists to answer
"which raws do I have". Album pages are not grouped at all: an album is a list
someone made, and it shows exactly what they put in it.
`TimelineRow` is a struct now. It had grown to five positional fields and was
about to grow to seven, at which point nobody can read a call site.
The gallery could show photos and nothing else: a photo deleted on the phone
stayed on the page for minutes, and a photo you wanted gone had to be deleted
on another device. Both are now handled here.
Deleting needs a uid-addressed request, because `Request::Delete` takes a
mountpoint path and the photos volume is not in the FUSE mount. `TrashNodes`
trashes through the SDK and answers per-uid outcomes, so a partial failure is
reportable; the daemon then drops those rows with `Db::photos_delete`, album
membership included, rather than leaving the gallery to wait for the next
timeline refresh. The GUI removes the tiles immediately with an Undo toast and
puts back anything the server refused — the photos are in Proton's trash and
stay recoverable there either way. Selection is Ctrl/Shift+click, the Select
toggle or Delete in the lightbox.
Remote deletions arrive on their own now. The Drive volume and the photos
volume have separate event streams, so the photos volume gets its own poller
and its own cursor. Trash and delete events remove rows; anything else only
marks the timeline stale, because there is no inode space to converge on this
volume. With the timeline TTL down to 60 s and an explicit Refresh that waits
for the server instead of only clearing the freshness stamp, a photo deleted
elsewhere leaves the grid in about ten seconds.
The Photos grid laid every photo out as a centre-cropped square. That is
why portraits showed black bars and why a panorama was unrecognisable at
tile size: the tile's shape had nothing to do with the photo's.
Rows are now justified. Photos are taken in capture order until they no
longer fit the target height, and the row is then scaled to land exactly
on the right margin, so each tile is its own photo's shape and nothing is
cropped or letterboxed. The last row of a day stays at the target height
rather than being stretched — a day holding two photos should look like
a short day, not like a layout bug. Ratios come from the daemon where it
has one; where it has not, the tile is laid out square and the day
re-flows once a decoded thumbnail proves the real shape, on the existing
debounce so a screenful of decodes costs one re-flow. Extreme ratios are
clamped, so one strip of film cannot decide what a row looks like.
Ctrl+scroll and Ctrl+± now move the target row height, and the grid is
tighter to match: 2 px gaps, smaller heading margins, a 6 px radius and
no card behind each tile, so the page reads as photographs rather than
as a deck of cards.
Thumbnails also stopped disappearing on scroll. The texture cache was
evicting in insertion order — which is precisely what a scroll back up
asks for again — so it is now least-recently-used and holds 1500 rather
than 600, which at the new density is several screens instead of under
two. A batch tops itself up with the photos just past the rows on
screen, in the direction of travel, and once the queue is short the
near-miss tiles are fetched rather than dropped.
Teardown flagged the FUSE worker pool closed but never joined it, so the
process could drop the tokio runtime while a worker was still inside a
job — which is where 2026-09-18's "A Tokio 1.x context was found, but it
is being shutdown" panic came from. `Workers::stop_and_join` now waits
for the jobs in flight, bounded at 10 s so a worker wedged on the network
cannot hold the stop the user asked for; what is still stuck is named in
the log and shutdown continues around it.
The queues stay unbounded — the only caller that could feel backpressure
is fuser's dispatch loop, and blocking that is the stall the pool exists
to avoid — but a lane now logs its depth every 256 jobs, so a queue that
keeps climbing is visible before it is reported as a slow mount.
Documents the hang as B91, with the journal evidence, what made it
undiagnosable, and the candidates the evidence does not yet separate.
A supervisor thread ticks every 15 s and does three things: it WARNs
about a worker that has held one job for two minutes, a control request
that never returned, or a lane that has not completed anything while its
queue is non-empty; it samples resident size and the pending-op count
into the log every five minutes; and it answers the systemd watchdog.
The watchdog ping is deliberately not a heartbeat from a thread that
does nothing else — that would keep the unit "healthy" through exactly
the hang it is meant to catch. It goes out only after a real round trip
over the control socket, so it means "a client can still talk to this
daemon", which is the property that failed on 2026-09-18.
`sd_notify` is spoken directly rather than through libsystemd (READY,
WATCHDOG, STOPPING), including the abstract-namespace address; off
systemd every call is a no-op.
The unit gains `NotifyAccess=all` (rather than `Type=notify`, which
would fail the unit on the start timeout when no login is stored yet),
`WatchdogSec=120`, `Restart=always` — a hang is not a failing exit code
— and `MemoryHigh`/`MemoryMax` as a backstop against the 5.2 G growth
the hung run showed.
On 2026-09-18 the daemon hung: 43 minutes of CPU over 20 hours, 5.2 GiB
resident, silent from 17:10 until a manual restart the next day, and no
panic. Nothing in the journal said what it had been waiting on, and
nothing in the daemon could be asked.
- The worker pool publishes per-thread state: whether the thread is busy,
how long it has been in that state, and the label of the job in hand.
Every FUSE handler that hands work to the pool now names its job
(`read`, `lookup`, `rename`), so a stuck worker is named rather than
merely counted. Queue depths and per-lane completion counts are
mirrored outside the queue lock.
- `Request::Diagnostics` / `pdfs diagnostics` reports those, plus
resident size, the control handler count against its limit, the
in-flight control requests with their ages, and the pending-op count.
- Built to answer while the daemon is wedged: atomics and `try_lock`
only, and the one field that needs the database reads it on a throwaway
thread with a 500 ms deadline.
The trash is a flat list of uids, but a delete has a shape: a folder, and
often items inside it that were trashed separately beforehand. Restoring
one of those in isolation is not what it means — a folder came back
without the contents deleted with it, and a file came back inside a
folder that is still trashed, which is to say nowhere the user can see.
- Schema 29: `trash.parent_uid`, filled by the trash refresh from the
node's parent, plus an index for the walk.
- `expand_restore` takes the connected piece of the trashed tree around
what was asked for (every trashed descendant, every trashed ancestor)
and orders it into waves, shallowest first: the server cannot put a
node back under a parent that is still trashed. A uid the listing does
not know about is restored on its own, because the listing is
materialised in chunks and can be stale.
- `Core::restore` restores wave by wave, still streaming per-node
outcomes, so one node the server refuses leaves the rest restored.
The SDK bump brings the 6cbf2f44 port: permanent API errors are no
longer retried on block transfers, expired block URLs are re-minted on
the whole-file and public-link download paths, and a server-supplied
Retry-After is capped at 120 s.
The "This computer" indexer walks $HOME, and `default_excludes` only kept it
out of the Drive mountpoint and our own state/cache dirs. A home directory
that also holds third-party FUSE mounts (sshfs, rclone) got walked into.
`scan` does ask for `same_file_system(true)`, which looks sufficient and is
not: `ignore` implements it as `is_same_file_system` -> `device_num(path)` ->
`path.metadata()`, run after the directory is queued. Learning that a mount is
foreign requires stat'ing it first, and against a mount whose server is gone
that stat never returns.
The consequence is worse than a stalled scan. The blocked thread sits in
uninterruptible FUSE wait, so it ignores SIGKILL: the daemon can never exit,
systemd's stop times out, and the unreapable process keeps the cache.db lock
the next start needs, turning one dead mount into a permanent restart loop.
No userspace recovery exists once a thread is in that state, so the fix has to
be to never enter it.
Exclude every mountpoint strictly below the scan root, read by path from
/proc/self/mounts (octal-unescaped, so a path with a space still matches).
`filter_entry` runs before the device stat, so the walker never touches them.
Re-read per scan rather than cached at startup: a mount that appeared since
the daemon started is the likeliest to be half-alive.
This does not change what is indexed — a nested mount is a different device,
so it was already going to be skipped. Only the stat in front of that decision
goes away.

- keyring 3 -> keyring-core 1 + dbus-secret-service-keyring-store 1
(crypto-rust). Same libdbus Secret Service backend; with no target the
store matches items keyring 3 wrote, so stored sessions survive.
- ksni 0.2 -> 0.3 via the blocking API, with assume_sni_available so a
tray that starts before the SNI watcher waits instead of failing. Drops
the clap 2 / atty chain (Dependabot atty advisory).
- gtk4 0.11, libadwaita 0.9, webkit6 0.6, rusqlite 0.40, fuser 0.18,
directories 6, sha1/sha2 0.11, base64 0.23.
- A queued rename that also changes folder now lands as one `move-multiple`
request carrying the target name instead of rename-then-move, so there is
no half-applied state and no second call for stale name requirements to
hit (B46 follow-up). A destination name collision moves under a conflict
name in one step; same-folder renames still use the rename endpoint.
- Shared with me shows the inviter and invite date (GUI subtitle, `pdfs
shared-with-me`), with a warning when the invitation signature does not
verify against the claimed inviter's keys. `DirEntry` gains `shared_by`,
`shared_at` and `shared_by_unverified`, all serde-defaulted.
- Bump `proton-sdk` / `proton-drive-rs` to 0.6.3 (anonymous-node moves,
`TrashTime` trashed detection).
The login backoff had no wake-up path. A unit started at boot sits in
wait_for_session and reaches the ceiling within ~90s; the user then signs
in and `enable --now` is a no-op on an already-active unit, so the daemon
kept sleeping and the mount appeared up to a full interval late.
- service::enable_start now runs `enable` + `restart` instead of
`enable --now`, so the GUI login and the tray's Connect interrupt the
sleep immediately and still start a unit that is down.
- `pdfs login` restarts the unit when it is already active. It stays out
of `enable` on purpose, so a headless setup driving `pdfs daemon` by
hand is left alone.
- Lower the backoff ceiling from 60s to 15s. It is still an 80% cut in
keyring/D-Bus wakeups (28,800/day -> 5,760/day) and it bounds the
worst-case latency for paths that never touch systemd.
Also corrects the flat-3s-poll figure in the doc comment: 86400/3 is
28,800 checks a day, not 48,000.
The daemon's wait-for-login loop slept a flat 3 seconds between checks and
never gave up, so an enabled service with no saved session polled the keyring
28,800 times a day. Each check is more than a sleep: auth::load() builds a
fresh keyring::Entry, so every iteration opens a new D-Bus connection to the
Secret Service and negotiates a session on it.
Back off from 3s to a 60s ceiling and say "not logged in" once at INFO rather
than on every iteration, which also stops the journal filling with tens of
thousands of identical lines.
The wait is extracted into wait_for_session() taking the load and sleep calls
as parameters, so the schedule is testable without a keyring and without real
time passing.
