`pdfs copy PATH... NEW_PARENT` sends a new control request, Copy, which
copies a file with its content or a folder with its subtree on Proton
Drive through proton-drive-rs's copy_node. Nothing is downloaded or
uploaded. A name already taken in the destination gets the next free
" (n)" suffix through get_available_name.
A copy cannot wait in the queue, because Drive copies what it holds.
So it is refused offline, and while the mount still owes Drive part of
the node: a local placeholder, a queued op, unsaved writes, or, for a
folder, any queued op at all. Local-first does not change this.
DriveApi gains copy_node and get_available_name, and the fake drive
copies subtrees, so a FUSE sim test covers the copy, the suffix, the
folder subtree and both refusals. The activity feed logs a new Copy
kind, translated in every catalog.
Needs the proton-drive-rs release that adds copy_node; until then, build
with a [patch.crates-io] pointing at proton-sdk-rs.
A simulated daemon could not add a synced folder, so nothing that moves
between a mount, an on-demand folder and a mirror folder could be tested
without a real account.
Listing and registering devices now go through DriveApi, and the fake
Drive keeps the account's computers, each with a root folder outside My
files. The simulated daemons also read their config.json from a scratch
XDG directory instead of the developer's own: an adopted device of the
real account made every sync folder fail to register against the fake
Drive.
ARCHITECTURE.md described the 2.x write path, where namespace changes
waited for Drive and every mount had its own inode space. Rewrite it
around the local tree (lid, inode = lid + 1, local~<lid> stand-ins), the
queue and its 16 drain workers, sync issues, and the remaining split
between the mount and the mirror engine. Drop the pins.json claim; pins
moved into the database at schema v5.
TESTING.md gains the simulation runs and loses the per-case narrative
that --list and BUGS.md already carry. ROADMAP.md takes over the
post-3.0.0 items from the milestone status file.
Remove MILESTONE-3.0.0-STATUS.md (a working log) and UI_UX_PLAN.md (the
2.x design audit). Code comments and CI that cited the untracked
docs/MILESTONE-3.0.0.md now point at TESTING.md, ARCHITECTURE.md and
ROADMAP.md. Threat-model links follow the section to §10.
An upload that landed let go of its blob before the tree had its node. A
write open in between took the base it sampled at its start, the revision
the upload replaced, found none of its bytes cached, and queued an
incomplete revision; the next write open failed with EIO.
The drain keeps the landing node aside until the tree has it, and a write
open with no queued revision takes its base from that node, or from the
tree as it is when the handle goes in. The fake Drive can hold the drain
in that window (`hold_next_landing`).
mount() becomes a thin wrapper over mount_with(), which takes the
DriveApi to reach Drive through and a Host. The daemon's Host is
unchanged: stopped by SIGTERM or SIGINT, installed at the same point as
before, and indexing the user's home. A simulated daemon is stopped over
a channel and skips the home index, so several can share one test
process without walking the developer's home.
The account quota moves onto DriveApi. It was the only call outside the
trait that marks the link lost, so a simulated daemon would have gone
offline on it; the FakeDrive now also models a full account
(InsufficientQuota).
sim::daemon starts one daemon on its own state directory with a real
FUSE mount, and a smoke test (ignored; needs /dev/fuse) checks a local
write lands, a remote write arrives, and a write made offline lands once
the link is back.
`Core` held a concrete `ProtonDriveClient`, so no test could make Drive
answer late, answer stale or not answer. This is the first step of
phase 0 in docs/MILESTONE-3.0.0.md.
`DriveApi` (`crates/pdfs-fuse/src/drive.rs`) covers the calls the sync
core makes: listings, events, creates, uploads, downloads, renames,
moves, trashes and restores. `ProtonDriveClient` implements it by
forwarding. `Core::drive` holds it, and every call of those methods now
goes through it. Sharing, Photos, devices, invitations and public links
stay on `Core::client`.
The trait takes readers and writers as trait objects, and
`impl dyn DriveApi` puts the client's generic signatures back, so call
sites read the same. Block reads go through `RevisionRead` instead of
the SDK's `RevisionReader`, which only the SDK can construct.
No behaviour change.
