A mirror upload that Drive did not list yet when it was read back left a
baseline row with no revision id. The next walk reused the recorded size
whenever the modification time matched, and a row without an id never
counts as moved. So a revision another computer saved in the same second
looked unchanged and never arrived (B254). The B250 simulation hit this
about one run in five on CI.
A row without an id now reuses its size only while Drive gives no id
either. Otherwise the walk reads the size, and an unchanged file gets
Drive's revision id written into its row, so each row costs one extra
read. Rows from before schema 44 are read once after upgrading.
Add the window size and the narrow layout to the 3.5.0 changelog with
B253, document the `window` config field, and explain in the
troubleshooting guide why a two-password account asks for its mailbox
password after every reboot, and how to keep it unlocked.
The app read the session with `auth::load().ok()`, so a locked keyring, a
Secret Service that was not up yet or any D-Bus error showed the sign-in
form as if nobody were signed in. The session was still saved (B253).
Keyring errors are now kept apart from "not signed in". The login page
shows a banner saying the saved sign-in could not be read, with a Retry
button. The app tries again after 2, 5, 10 and 30 seconds and opens on
Files once the keyring answers. The login page's header also loses the
back button the collapsed split gave it.
Translated into every shipped language.
While signed in, the sidebar never collapsed. The window could not get
narrower than the sidebar plus the widest page, about 950 pixels, so on a
small or scaled screen the minimize, maximize and close buttons ended up
off-screen.
- The page stack is no longer homogeneous, so only the page on screen sets
the minimum width.
- The selection bars of My files and Photos scroll sideways instead of
holding the window at their full width, even while hidden.
- Below 760sp the sidebar and the page take turns, with a back button,
and the My files search entry narrows. Picking a sidebar row opens the
page.
Every page, in English and in German, now fits in a window 480 pixels
wide with its window buttons visible.
The app always opened at 980x680. It now keeps the unmaximized size and
whether the window was maximized in config.json under `window`, written
when the window closes and when the app quits with it still open. A
missing field, or a saved size below 480x400, opens at the old default.
Add B248 to B252 to the bug ledger, the shared-device feature and schema 44
to the 3.5.0 changelog, and describe the join flow, per-machine profiles,
conflict copy names and the mirror's multi-writer rules in the user guide,
recovery guide, CLI and configuration references and the architecture notes.
Two or more computers can now sync the same folders through one device in
Proton Drive. `pdfs devices join UID` and "Sync With This Computer…" on
another computer's row adopt that device as this machine's and then offer its
folders for syncing here, like a restore. Unlike "Continue This Backup Here",
the other computer goes on syncing, and the confirmation says that changes
and deletions on one reach the other.
Translated into every shipped language.
Every computer that synced into one device wrote the same profile.json, so
each save replaced the other computers' folders with its own (B252). Each
machine now writes profile-<machine id>.json, where the id is random, made on
first use and kept in machine-id next to config.json. No host identifier goes
to Drive.
Restore reads every profile in .proton-drive-linux, including the shared one
older clients wrote. A folder's proposed path and mode come from this
computer's own profile, otherwise from the newest one that has the folder.
The legacy file is left as it is, so a client before 3.5.0 still finds it.
A mirrored folder assumed it was the only client writing to its folder on
Drive. With a second computer syncing the same folder, edits could be lost:
- The first sync took a same-size file at the same path for the same file.
It now records the baseline only if the local file's SHA-1 matches Drive's
digest, and otherwise keeps a conflict copy (B248).
- An upload replaced a revision another client had committed since the pass
looked. The upload now checks Drive's active revision first, and an edit
that read back with someone else's digest is left for the next pass to keep
as a conflict copy (B249).
- A download recorded a revision committed while it ran as synced, so that
edit never arrived. The baseline now records the revision the pass planned
to download (B250).
- Conflict copies now carry the computer's hostname, so two computers do not
make the same name on Drive (B251).
The baseline gains the revision id it was synced at (schema 44), and a new
revision counts as a remote change even at the same mtime and size.
A Takeout photo with no sidecar and no date in its name was filed under
the day of the import, and the app dated uploads by modification time.
A new `exiftime` module reads DateTimeOriginal (then DateTimeDigitized)
with its offset. Takeout uses it for undated photos it copies out for a
thumbnail, and the daemon uses it for app uploads before falling back to
the modification time (B244).
Opening a file or a location stat'ed the mount on the GTK main thread, so
a hung mount hung the app. The browser now uses the launcher's bounded
worker check (`present_within`, 2 s), and opening a location runs on a
thread. Every child the GUI starts is also waited for on a thread, so it
no longer stays a zombie (B243).
The viewer decoded each full-size photo, read its EXIF and stat'ed it on
the GTK main thread, freezing the app for a large photo. That now runs in
gio::spawn_blocking, and a result for a photo the user has left is
dropped (B242).
The viewer's handlers held strong references to the viewer and its
window, which own them, so every closed viewer stayed in memory with its
full-size photo. The share dialog's row handlers had the same cycle with
the dialog state. The handlers now hold weak references, and the viewer's
one strong handle is dropped on close with the photo (B241).
Only `pdfs daemon` marked itself non-dumpable, though `mount`, `login`,
`unlock` and `logout` hold the same passphrases or tokens. All five now
do. The file-manager script also passes each path after `--`, so a file
named like an option stays a path (B240).
`import-google-photos --wait` and `redate-photos --wait` exited 0 however
the run ended, and a run that failed as a whole left no summary, so the
CLI said no import had run and the app said it finished. Failed runs now
leave a summary with the reason, `--wait` exits 1 on failure, cancel or
failed photos, and the app shows the reason (B239).
The name checks the drain makes before each create, rename and trash,
and the wake of ops waiting for a name, read the whole queue, which made
a large offline batch quadratic to drain. Schema 43 adds an index on
pending_op(kind, name) (B238).
A reconnect made every failed op due at once, quota and access refusals
included, and ops that failed together retried in the same second. The
doubling also stopped at 128 s, short of the 300 s maximum. Reconnects
now move up only unrefused ops, and the backoff reaches its maximum with
a per-op spread of up to a fifth (B237).
Takeout imports, re-dates and the app's photo upload all sent an empty
thumbnail list, so the photos showed blank in Proton's apps. Re-dates and
app uploads now make thumbnails from their file. A Takeout photo that can
have one is copied out of the archive to the private staging folder,
thumbnailed and uploaded from the copy (B236).
Each photo was ranked against every sidecar in its folder, so a folder
of 10,000 photos took about 30 s to scan. The sidecars are now indexed
by stem and each photo is ranked only against the stems a few range
lookups return: 0.1 s for the same folder, with the same matches (B235).
Nothing stopped `/`, the home folder, the Proton Drive mount, the app's
own state or cache, or a folder nested in another root from becoming a
sync root, and a restore took a path from another machine's profile as
it was. One validator, `syncroot::problem`, now runs where roots are
added and restored, on paths resolved through symlinks with `..`
refused (B234).
Logout only deleted the keyring entry, so the session's tokens stayed
valid on Proton's side. It now ends the session first (DELETE auth/v4,
bounded to 10 s) and signs out locally either way. `pdfs logout` says
when Proton could not be reached (B233).
Rows, toasts and status page descriptions parse their text as markup by
default. Shared item names, inviter addresses, device names, link URLs,
paths, EXIF values and daemon errors went in unescaped, so a name with
`&` showed as an empty row and other names were drawn as markup. Those
rows and toasts now use plain text, and status page descriptions are
escaped (B232).
The upload deadline assumed at least 32 KiB/s. Under an upload cap shared
by every drain worker and sync task, a large file ran out of time on every
attempt, took the mount offline and restarted from byte 0. The deadline
now counts the upload's share of the cap as the slowest rate when that
share is lower (B231).
- A gap-filled revision blob is recorded as complete once filled, so a
retry after a lost upload answer recognises its own bytes on Drive
instead of forking a conflict copy (B228).
- Commits that accept a change into the queue run at synchronous=FULL,
so an op `close()` reported as done survives a power cut (B229).
- A queued create's adoption window starts at its first send, not when
it was queued, so a create queued offline no longer takes another
device's empty node of the same name. A send record that does not
parse is kept instead of overwritten (B230).
A read on a write handle was answered on the dispatch loop to keep its
order with the handle's writes, and when the bytes it asked for were
neither written nor cached it downloaded them there, holding every request
of the mount for up to the read deadline. The loop now answers from the
scratch file and the local caches only, and hands a read that needs a
download to a transfer worker with the handle as it was when the read came
in (B227).
No package ships a separate debug package, and the unstripped binaries were
43, 24 and 12 MB. LTO stays off, as the packaging comments already said the
release profile kept it, and unwinding stays on for the workers that catch
panics.
Thumbnails were decoded without the EXIF orientation, so a portrait photo
stored as landscape pixels plus a tag got a sideways tile, and the drain
uploaded that thumbnail to Drive for every client to show (B226).
The prefix rule for sidecars whose names Google cut at 51 characters also
matched names that were never cut, so IMG_1.jpg's sidecar gave its title
and date to an IMG_12.jpg that had none. It now applies only to a sidecar
name at the cap. Edited copies, which have no sidecar of their own, take
their original's date by a rule of their own and keep their own name
(B225).
load_config gives defaults for a file it cannot read, and every setter
loads, changes one field and saves. The first settings change after the file
was damaged therefore wrote defaults over the mountpoint, the adopted device
and the ignore rules. save_config now refuses while the file on disk does
not parse, and the first-run default is written atomically with mode 0600
(B223).
flush answered ok at once and release synced the scratch file, but close(2)
only returns what flush answers, so a full disk at close was reported to
nobody. flush now syncs a handle with writes on a worker and returns ENOSPC,
EDQUOT or EIO; release then finds the pages on disk instead of writing a
whole file back on the dispatch loop. fsync on a descriptor opened for
reading no longer fails with EBADF (B222).
fallocate passed any mode through and tracked only a punched hole or
growth: a zeroed range came back from the remote base at commit, and a
collapse or insert corrupted the file. Unsupported modes now get EOPNOTSUPP,
zeroed ranges count as written, the real errno is returned, and the state
lock is not held across the syscall (B224).
A cold listing allocated the local id of every new child in a write
transaction while it held the global state lock, then marked the folder
listed, still under it. Every inline handler of every mount waited on that
transaction, and the transaction on the write connection the drain shares.
The ids are now allocated before the lock is taken, and the folder is marked
listed through the outbox after its children's rows, so a crash in between
no longer leaves it recorded as complete and empty (B221).
A shared folder's listing is fetched again once it is a minute old, and that
fetch ran on the dispatch loop whenever the old listing was still resident,
so every request on the mount waited for Drive (B219).
Thumbnail downloads, size upgrades and the Shared with me listing had no
deadline of their own. On a stalled link each held a mount thread for the
SDK's retry budget, and a folder of photos filled the three metadata workers
that every cold lookup and rename needs. Offline, an uncached thumbnail is
now answered as absent, and these calls give up after 20 or 60 seconds
(B220).
PRAGMA integrity_check and the row counts behind pdfs cache inspect read
the whole file, 34 s on a 567 MiB database, and they held the write
connection while they did. Every write in the daemon waited behind them.
They now read a WAL snapshot on a pooled read connection (B218).
FTS5 keeps deleted entries until their segments are merged, which with
these indexes is close to never. On one machine local_fts held 317 MiB for
40,000 paths, against 20 MiB rebuilt, and search ran four times slower. The
indexes are now compacted once a day after a local scan. A scan that hit the
entry cap or lost a batch no longer prunes the paths it never reached, which
the next scan used to add back (B217).
A database SQLite reported as corrupt at open was moved aside and replaced
by an empty one, on the grounds that everything in it is fetched again. The
queue of writes Drive has not received, the mirror baselines and the pins
are not, so they were lost. They are now copied out of the damaged file,
read only and table by table, into the new one (B216).
Five ways a mirror pass could lose files:
- A folder deleted on Drive was removed here with everything in it, including
new files and edits whose uploads had just failed for want of a parent, and
ignored content such as .git. Such a folder now stays and is created on
Drive again (B211).
- A node the SDK could not decrypt was missing from the remote walk and so
read as deleted on Drive. A short listing or an unreadable size now leaves
the affected paths out of the pass, and a pass in which no synced path is
left on Drive is refused (B212).
- A file Drive deleted was removed here even when it had been edited since
the scan. It is now checked again first, and kept (B213).
- A folder deleted here was trashed on Drive although another device had just
put new files in it. It now stays on Drive (B214).
- A decrypted name holding / or .. became a path outside the sync folder, and
failed the whole listing in the mount. Such names are left out (B215).
Issue #40: after a password reset the daemon failed every mount with
"failed to decrypt: missing key", and the app waited on "Connecting…"
because control.sock was never created. proton-drive-rs 0.9.1 now
creates a new My Files volume when no active regular volume is left,
as the web client does.

Proton answers a sign-in it blocks for abuse or rate limits with code
2028 and the text "This version of the app is no longer supported". The
SDK read 2028 as Unknown, so the app passed that text through and told
users to update a current release (issues #28, #39).
- deps: proton-sdk and proton-drive-rs 0.8.3, which name 2028 Blocked
- core: error::sign_in_blocked detects it
- gui: the login page says Proton is refusing sign-in for now and that
waiting helps, translated in every catalog
- cli: pdfs login adds the same hint to the error
- cli: pdfs diagnose warns instead of failing when cache.db does not
exist yet; the daemon creates it after the first sign-in
