A user switching from a Windows PC to Linux had two half answers:
adopting the old device makes this machine back up as it, and restoring
its folders keeps them in the old device's tree. Neither puts the data
under this machine's own device.
Device roots are separate shares on the main volume, so each top-level
folder of the other device can move under this device's root in one
server-side move. Nothing is uploaded again, and the other device stays
registered, without those folders.
- core: `Request::MigrateDevice { uid }` and
`Db::sync_folder_set_share`
- fuse: `Core::migrate_device` moves every folder, suffixes a name
already taken here with the other device's name, keeps going past a
failed folder, and re-points sync folders that already tracked a
moved folder at the new share
- cli: `pdfs devices migrate UID [--yes]` confirms, moves, then runs
the ordinary restore picker
- gui: "Move to This Computer…" on another computer's row, followed by
the restore picker
- i18n: translate the new strings in every catalog
- docs: CLI.md, USER_GUIDE.md, RECOVERY.md, ARCHITECTURE.md, changelog
A two-password account signed in with its login password as the mailbox
password, so the key chain never unlocked and the daemon retried forever.
Login now asks for the mailbox password and checks it against the account
(proton-sdk 0.8 `unlock`), so a typo is a retry. The password is never
stored: the keyring blob keeps the per-key passphrases instead, and for a
two-password account only when the user opts in (`--remember`, or the
"Keep unlocked on this computer" switch). By default they live in the
kernel keyring for the login session and the account is locked after a
reboot until `pdfs unlock` or the app supplies them again.
- core: kernelkey module, Error::Locked / WrongMailboxPassword, unlock,
lock, key_state, ready; blobs written by 3.0.x are migrated on first
start; token refresh updates only the tokens in the stored blob
- cli: `pdfs unlock [--remember]`, `pdfs lock [--forget]`; status and
diagnose report the key state; the daemon waits while locked and is
marked non-dumpable
- gui: mailbox password dialog at sign-in and on open, locked tray state
- po: all catalogs translated
- bump to 3.1.0, depend on proton-sdk and proton-drive-rs 0.8.0
Refs #26.
The watchdog is armed when the process starts, but only the mount's supervisor
pinged it. A daemon waiting for a login or backing off after a failed mount
(#26: key unlock failing) was aborted after WatchdogSec and left a coredump
instead of its error. Sleep through idle_sleep in those stretches; the mounted
ping still has to pass the control-socket probe.
A refused change was only on the Sync page. A folder listing now carries
each node's issue (by local id, so a file not yet on Drive has it too),
and the browser's badge ranks it first, folders included, with the
issue's explanation as its tooltip. The event sampler publishes Files
when the set of issues changes, so the badge comes and goes with it.
A change Drive will not take could be exported or retried, never let go
of. The Sync page's Discard button (with a confirmation) and
`pdfs sync discard <id>` drop it: a node made here goes, as if deleted
before it was sent; a node Drive has goes back to what Drive has, under
the same inode, with every change queued on it, while what is queued
below it stays. A change on the wire or an open file is refused.
A stop joined every background thread for as long as each took. The sync
engine's mirror pass calls Drive with no deadline, and a stop that waited for
it was killed by systemd at TimeoutStopSec. The stop now waits up to 10 s for
the background threads and FUSE workers together, names any still running, and
the runtime shuts down within 2 s.
A change Drive refuses because the storage is full, access was taken away,
its folder is gone, a folder limit is reached or the change was rejected
used to look like any other failure until six attempts had passed. The
drain now sorts the refusal into an issue and stores it on the queued op
(schema 38), so it needs attention at once in the app, tray and CLI. The
change stays queued and is retried; nothing is deleted.
The queue listing carries the issue and whether the op has file content.
ExportPendingOp copies that content to a new file: the Sync page offers it
as an Export button next to each issue, and the CLI as
`pdfs sync export <id> <dest>`. `pdfs sync issues` lists what needs
attention, and `pdfs sync queue` shows the issue per change.
docs/MILESTONE-3.0.0-STATUS.md tracks what is left for 3.0.0.
A new folder, a new file, a rename or a delete through the mount no longer
waits for Drive: it is recorded locally, the call returns at once, and the
drain sends it as it does offline. `"local_first": false` in config.json
brings back the old path for this release.
Fixes found by the simulation runs on the way:
- B129: a file deleted while its first upload is on the wire is trashed once
the upload lands.
- B132, B140: files made in a new folder survive a restart; a landed folder
hands its queued children over in the stored node too.
- B138: a create waits for the rename or trash that frees its name.
- B139: a file closed while its first upload lands keeps its last write.
- B141: a rename a worker holds stays queued, and the newer one waits behind
it instead of racing it.
- B142: a rename of a file whose create lands meanwhile goes to the uid Drive
gave it instead of answering EBUSY.
- B143: a create whose read-back fails as the link drops is adopted before
the next op for it is sent, so its next write is not a conflict copy.
`pdfs ls | head` ended in a "Broken pipe" panic once `head` had its
lines, because std's `println!` panics on a failed write.
The CLI now shadows `println!` and `print!` with versions that exit 0 on
a closed pipe and report any other write error, such as a full disk,
with exit 1. Restoring the default SIGPIPE would also stop the panic,
but the same binary runs the daemon, which must not die when a socket's
peer goes away.
`pdfs rm ~/Downloads/x` answered "is not under the mountpoint" while
`pdfs move` took the same path: the Delete, Rename and CreateFolder
handlers still read paths against the primary mount only (B88).
They now go through `route_change`, the router ResolveConflict already
used, renamed from `route_conflict`. It answers the request in the
inode space of the mount that owns the path.
An on-demand folder's root has a parent on Drive, so `pdfs rm
~/Downloads` would have trashed the whole synced folder from under its
mount. rm and rename refuse a path that names a mount's root.
The FUSE acceptance suite now runs on the signed-in account by default and
cleans up after itself; its first live runs found three daemon bugs.
- B101: a pwrite past EOF now authors the hole it leaves, so truncated bytes
no longer come back from the base. A write attached to a create while that
create uploads becomes a revision of the real uid instead of being dropped.
- B102: removing a folder drops the queued revisions of files below it, found
through the node tree, with their blobs and in-flight uploads. `pdfs rm`
now drops queued ops too.
- B103: each server call of a trash refresh times out after 120 s, so one hung
call can no longer freeze the trash listing until restart.
Acceptance suite: account mode with a manifest, lock and reaper; cleanup by
uid; queued ops naming a test root count as leftovers; new edge-case,
throughput and B100/B101 cases; the wide-directory case is split from the
deep tree and gets a doubled budget. Adds `pdfs trash --json`.
- A mirror download first copies the file out of the content cache when the
same revision is cached whole or block by block, so moving a file out of an
on-demand folder into a mirror costs no traffic for what was already read.
- `pdfs move a b c DEST` moves every source, reports each failure and exits
non-zero if any failed.
- Mirror-to-mirror moves rename with RENAME_NOREPLACE, so a name that
appeared at the destination after the check is never overwritten.
- The local copy a move out of a mirror drops is checked again just before
it is deleted; anything written into it meanwhile keeps the copy and is
uploaded as new by the next pass.
A move request with two absolute paths is resolved against every
location (My files, on-demand and mirror synced folders) and made as a
server-side move_node. The local side is levelled afterwards: mounts
forget and re-list, a mirror folder renames its copy and baseline along
or drops the copy once Drive holds it.
Anything only this disk holds is refused up front: queued ops, open
writes, unsynced or ignored mirror files and symlinks. The GUI Move
dialog gains a top-level list of locations.
The list and grid view from My files moves into widgets/file_list.rs as
FileList, so Trash, Shared with me and Shared by me share its columns,
selection, context menus, keyboard handling and list/grid switch instead of
each drawing its own rows.
Trash shows where each item came from and when it was deleted. Proton does
not expose the trash time through the SDK yet, so the daemon records when it
first sees a node in the trash (migration V35, trash_seen) and reports that;
the date becomes exact once proton-sdk-rs exposes Node::trash_time. Restoring
offers a Show action, and opening a trashed item explains that it needs to be
restored first.
Shared with me splits files and saved links into two views. Files show who
shared them, with a warning pill for unverified senders, the access they give
and when they were shared. Pending invitations sit in a banner that opens a
dialog to accept or decline each one. Several items can be left at once.
Saved links get their own list with open, copy and remove actions.
Shared by me gains a filter (all, links, people, expired links) and columns
for location, people and link state, with a copy button for live links.
Several items can stop being shared at once, the page refreshes after the
share dialog closes, and a reload rebinds only the rows that changed so the
selection survives.
All catalogs are updated and complete.
A new pill next to the favorites filter narrows the timeline to the photos
no album of ours holds yet, so what is left to file is easy to find. A
RAW+JPEG pair counts as filed when any of its files is in an album.
PhotosTimeline gains an optional not_in_album flag; older front-ends omit it
and get the whole timeline. Album contents are fetched lazily, so the first
filtered page fetches the contents of any album not yet listed. Photos added
to an album while the filter is on leave the timeline at once.
ListDeviceRestorableFolders and RestoreDeviceFolders read another
registered device's folders and attach them with that device's share,
without changing this machine's cached device. The Computers page moves
restore into each computer's menu, and pdfs sync restore takes --device.
StopSharing / StopSharingByUid remove the public link, external
invitations, invitations and members, trying every step and reporting
what is still shared. Shared by Me gets a Stop Sharing… item and
pdfs unshare <path> works without an id.
The Share dialog validates addresses inline, shows spinners on buttons
while requests run, offers a link expiry and shows an existing link's
expiry.
New requests CreateAlbum, RenameAlbum, DeleteAlbum, AddToAlbum and
RemoveFromAlbum, backed by proton-drive-rs 0.6.6. The Albums view gains a
New Album button and a card menu with Rename and Delete; photos gain Add
to Album (menu and selection bar) and Remove from Album inside an album.
CLI: pdfs new-album, rename-album, delete-album, add-to-album,
remove-from-album.
Also fixes the album view state: the timeline filters are hidden on the
album grid, the header counts albums, Back keeps the grid and its scroll
position, and the timeline is only reloaded when an album replaced it.
Request::Search takes an optional folder scope (serde default, so older
front-ends keep searching everywhere). The GUI offers a This folder toggle
beside the search box and shows a Location column for hits; the CLI gains
pdfs search --in. Pins report whether a pinned file is cached, so pin-derived
search hits badge correctly.
User-visible strings, doc comments and docs now say "Favorite" and
"color", matching the `pdfs favorite` command; UI_UX_PLAN.md §8 records
the choice. The changelog's 1.11.x and Unreleased entries said schema 30,
but V31 (`photos.resolved_at`) shipped in 1.11.0. Adds the missing
release links for 1.10.0 to 1.11.1.
Every transfer charges the bytes it moves to its direction's rate limit,
a virtual clock shared by all transfers with a one-second burst, and sleeps
off any overshoot. On runtime workers the sleep goes through block_in_place
so FUSE reads keep their threads.
The caps are set live with SetBandwidthLimits, persisted to config and
applied at mount start. Preferences gains a Network group with debounced
MiB/s editors, and the CLI gains `pdfs sync limit --up/--down`.
Conflict copies under My Files are paired with their original and listed
over the control socket. The Sync page shows them with a resolve dialog
(keep original, keep copy, keep both under a new name), and the CLI gains
`pdfs conflicts` and `pdfs conflicts resolve`. Every resolution goes
through the Proton trash, and files that are open, being written or still
owed an upload are refused.
Backend (docs/UI_UX_PLAN.md B-1, B-2):
- Request::SetSyncPaused { paused, until } pauses the drain worker and the
mirror reconcile. FUSE reads, write staging, the watcher and the poll keep
running. The pause is persisted in the `state` table (`sync_paused_until`),
so it survives a restart; a timed pause ends by itself through a timer
thread, re-armed on mount. Resuming wakes the drain and runs a full
reconcile. Response::Status gains `paused` and `paused_until`.
- Request::ListPendingOps lists the queue with paths, attempts, last error,
next attempt and parked/failing flags. Request::RetryPendingOp { id } makes
one backed-off op (or every failed one) due now. Parked ops are never
un-parked and nothing is dropped from the queue.
Front ends:
- Sync page: a status card with Pause/Resume (split button with 1 h, 8 h and
24 h pauses) and a "Waiting to Upload" list with Retry now and Retry All.
- The sidebar strip and the tray show the paused state; the tray gains Pause
Sync / Resume Sync and names failing changes.
- CLI: `pdfs sync pause [--for 30m|1h|2d]`, `pdfs sync resume`,
`pdfs sync queue`, `pdfs sync retry [id]`; `pdfs status` reports a pause.
Not in this phase: merging Activity into the Sync page, discarding a queued
op (needs a recovery copy first), and per-folder pause.
A timeline refresh resolved every photo's node to learn its name, media
type, favourite tag, content hash and photo relation — 63 round-trips for
a 12,445-photo library, minutes of work, repeated every time the timeline
went stale sixty seconds later. None of that metadata changes on its own,
and when it does change the event feed names the node it changed.
`photos.resolved_at` (schema v31) records that a photo's node was read.
The refresh resolves the photos without that mark: the ones it has never
read, and the ones a remote event marked stale. An existing timeline is
backfilled as resolved, so upgrading does not re-read the library once.
Remote changes now name what they changed instead of asking for
everything. `classify_photo_events` turns a `NodeUpdated` into
`photos_mark_unresolved(uid)`, so a favourite toggled on a phone costs one
node read rather than the whole library; a local toggle is claimed as our
own echo, because the feed replays it and a `NodeUpdated` carries nothing
that says what changed. A continuity loss and `refresh photos --full` drop
every mark, which is the way back to a whole-library read.
Along the way: `photos_replace` never kept a photo's name, so a photo the
SDK could not decrypt was renamed to nothing on every refresh — and the
tab split and the RAW+JPEG grouping are both derived from the name. It is
kept now, and a row that *was* resolved is authoritative instead, so a
photo unlinked from its main elsewhere finally loses its `main_uid`.
`TIMELINE_ENRICH_CHUNK` is 150, matching the SDK's own `MAX_BATCH_COUNT`:
a chunk of 200 was split there into a full request and a 50-uid tail.
Three things the 12,445-photo library showed that the tests did not.
A Pixel raw capture is two files named after the role each plays —
`PXL_….RAW-01.COVER.jpg` and `PXL_….RAW-02.ORIGINAL.dng` — so their stems differ
and the pairing rule never saw one shot. The marker is now cut off before names
are compared, narrowly: digits, then one role word, so an ordinary name that
happens to contain `.raw-` keeps its stem. Fed the real library's first 40 rows
through the grouping, they collapse to 21 tiles.
A raw that has a JPEG beside it is now painted with that JPEG's thumbnail, which
the server usually already holds. The Raw tab costs no raw download and no raw
decode for those tiles. Raws are found in one batched read, so an ordinary page
pays nothing for the lookup.
Photos could not be moved to Trash at all: they live on the photo volume, which
the mount never holds, so no `nodes` row exists, every authority answered
`Unknown`, and the write check refused the whole library with "trash access: not
allowed". Membership of our own timeline is the authority that does exist for a
photo, and it now answers. An album photo on someone else's volume still fails
closed.
Refreshing the gallery then reported `io: Resource temporarily unavailable (os
error 11)` (B92). The daemon held the control reply until the whole timeline had
been re-read — 63 batches of 200 nodes for this library, minutes of work against
a 120 s read bound. The daemon now answers as soon as the refresh is running,
`PhotosRefreshStatus` reports when it is done, and both front ends follow it: the
gallery reloads the page when it clears, and `pdfs refresh photos` blocks so the
command still means what it says. Each refresh logs its photo count, batch count
and duration.
Released as 1.11.0.
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.
- 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.
Refs #21
B69 — spurious `(sync-conflict)` copies came from `(mtime, size)` being used as a
revision identity. The server re-stamps a sealed revision with its own commit
time, so the drain diverted a write into a conflict copy of its own base; and
`plan_file` classified a no-baseline (local, remote) pair as `Conflict`, forking
every pre-existing file on first reconcile.
- `Baseline` carries `revision_id` (from the SDK's new `active_revision_id`),
captured at write-open and preserved across supersede/rebaseline.
`revision_changed` trusts the id and only falls back to `(mtime, size)` for
old sidecars.
- Planner gains `FilePlan::AdoptBaseline`: equal-size no-baseline pairs are
recorded, not conflicted. Divergent sizes stay a real conflict.
- New `sweep.rs` (`pdfs-conflict-sweep`, 5-min cadence) removes conflict copies
proven identical by size + `content_sha1` and surfaces divergent ones once as
an `ActivityKind::Conflict` entry. Never removes what it cannot prove.
B70 — browsers downloading into an on-demand mount had their in-flight temps
sealed as canonical revisions, exiling the finished file to a conflict copy.
`syncignore::is_transient_name` now recognises download/scratch temps, and the
on-demand `release`/`rename` paths hold them (`set_create_hold`) instead of
sealing until the name is finalized.
Workspace deps bumped to proton-sdk/proton-drive-rs 0.2.2 (registry, no patch).
Live validation against a real account still pending for both.

Scripts and health checks had to scrape formatted text, which changes whenever
the display does.
--json is global and applies to status, ls, pins, sync list, devices list,
transfers, activity, and cache inspect. Action commands keep their human
output; a script that needs to know whether one worked has the exit code.
Two decisions worth recording:
The daemon's own reply is serialized rather than a hand-built parallel
structure, so new fields reach the JSON without anyone remembering to add them
-- but the variant tag is stripped first. Serializing CtlResponse directly
yields {"SyncFolders": {"items": [...]}}, which would make every caller write
jq '.SyncFolders.items[]' and couple it to the name of an internal enum
variant. Callers get {"items": [...]}.
A daemon-side error prints its payload and then fails the command. The first
cut exited 0 after printing the error body, which was caught by running
`pdfs --json ls NoSuchFolder`: a script would have read a failed lookup as
success. The body is still emitted so `kind` is available, but the exit code
is what `set -e` and `if pdfs ...` actually test.
status composes its object by hand instead, being the one query that merges
the local keyring with the daemon -- including the logged-in-but-no-daemon
case, which has no daemon reply to pass through at all.

A corrupt database or an oversized cache previously left the user with no
answer but "delete the state directory and re-sync", which for a large
account means re-downloading everything to fix a problem that may have been
a few stale rows.
pdfs diagnose reports on paths, keyring, daemon, and mountpoint, and exits
non-zero if any check fails so it works in a health check. Every check is
written to run with no daemon, because that is the situation it gets run in:
a stopped daemon is reported as a finding rather than aborting the report.
Writability is tested by writing, since permission bits say nothing about a
full disk or a read-only remount.
pdfs cache inspect reports database size, reclaimable space, per-table row
counts, and cache usage; --deep adds SQLite's integrity check, opt-in because
it reads every page. The report distinguishes "checked and clean" from "not
checked" rather than letting an empty problem list imply a clean bill of
health it never gave.
pdfs cache vacuum checkpoints the WAL and compacts the database.
Deliberately no orphaned-cache-row pruning: ContentCache::reconcile already
rebuilds the index from what is on disk at every open, so a second pass here
would duplicate it against a worse view of the truth. The WAL is likewise
left to journal_size_limit, which already caps it -- a periodic checkpoint
would paper over a problem that no longer exists.
