The mount only ever went from offline to online: nothing marked it
offline again, so after the Wi-Fi dropped every create, mkdir, delete and
rename called Drive, waited out the SDK's retries for up to two minutes
and answered EIO. Background loops kept polling the dead link.
Connectivity now lives in pdfs-fuse's new link module and goes both
ways. A call that gets no answer (a transport error or a request
timeout) marks the mount offline; a probe thread checks every 2 s,
backing off to 30 s, and on recovery re-lists folders served from the
database, retries failed operations and wakes the drain. Interactive
calls get a 20 s deadline, so a dead link costs one slow call instead of
many.
While offline:
- create, mkdir, unlink, rmdir and rename fall back to the offline
queue instead of answering EIO;
- folders list from the database even when not marked listed, and are
re-listed once the link returns;
- reads of uncached data wait up to 30 s for the link, then retry once
within the 120 s read deadline;
- statfs serves the last quota instead of fetching, and quota refreshes
are single-flight;
- the event and photo event loops wait for the link instead of polling.
A create whose request timed out may have landed anyway. When the drain
replays it and finds a same-named twin of the same kind, created within
the last two minutes and still empty, it adopts that node instead of
making a conflict copy. The drain also leaves alone a name still held
by a queued trash.
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.
- Standardize POSIX unlink (EISDIR) and rmdir (ENOTDIR/ENOTEMPTY) checks
- Defer local directory eviction in mode switch until FUSE mount verification succeeds
- Enforce fsync before atomic renames in ContentCache store operations
- Add directory ancestor loop check in rename (EINVAL)
- Implement punch_hole interval tracking in fallocate
- Purge un-created local node write revisions on unlink
- Fix control socket permission race with octal umask 0o77
- Add unit tests for state, DB, and FUSE POSIX logic (208/208 tests passing)
