An installation that scans can still let files through: too large for the
scanner, an archive it could not open, or an upload that arrived while the
scanner was down. Both policies default to letting those through, and the
count of them is on the settings screen and the dashboard.
Everyone could see that except the one person it matters to. The uploader
sees the state on their own file and staff see it in the library; whoever
follows a public link saw the page a file that passed gets, having neither
chosen the policy nor any way to see the setting. On the hosted free plan,
where every upload is published behind a link, that is the whole audience.
The share page and the public file page in all four themes now carry one
line: "This file was not checked for viruses." Said plainly and without
alarm — nothing is known to be wrong with the file; what is known is that
nothing looked.
Only where this installation scans, and only for the three reasons that
mean a scanner let something past. A file from before scanning was
switched on says nothing: on an installation that has only just switched
it on that is every file, and saying it about all of them says it about
none of them.
The button was disabled on a library that had already been scanned
once, which is most of the time and exactly when somebody would press
it — after updating definitions, say. It now re-checks everything
rather than only what was never looked at, which is what its name says.
A rescan keeps each file available until its new verdict arrives, so a
full pass takes nothing offline. The two states it skips are a file
already waiting for its first verdict and one whose bytes are gone.
It is disabled for two honest reasons now — scanning is off, or a scan
is already running — and says which.
Results are green, amber and red: checked and fine, checked and could
not be read, checked and something was found. The badge gained a
warning variant to say the middle one, matching the amber the warning
alert already uses; before this a missing file wore the same red as a
virus.
A file found missing is also stamped with the time it was checked, so
it appears in the Activity list. It is a verdict like any other, and
without the stamp it was decided somewhere nobody could see.
A row whose bytes are gone was recorded as "the scanner could not be
reached". Wrong on screen, and wrong underneath: that is the one reason
the hourly sweep re-queues, so every orphaned row would have been
rescanned hourly forever.
It is its own state now, `missing`, and withheld rather than offered:
a client who sees a file listed and gets an error on the download is
worse off than one who never saw it. Staff still see it, marked, which
is the point — somebody has to decide what to do about it. The refusal
says what it is ("no longer on the server") instead of sending somebody
looking for a permission that would let them through.
A daily `projectsend:check-missing-files` finds them, whether or not
this installation scans for viruses: it is not a virus question, and an
installation with no scanner has exactly the same problem. It compares
one disk listing against the rows rather than asking "does this exist?"
per file, which on object storage would be a request per file per day.
Files that come back — a remount, a restored backup — are picked up on
the next run and re-checked rather than left for dead.
They are listed beside the orphans, which is the same fault seen from
the other end: bytes with no row, rows with no bytes. The tab carries
the count, each row says where the file should be, and removing one
takes the record with it through the deletion that already exists.
The dashboard says how many there are, and so does
`projectsend:status`, because a fleet-wide jump in this is a storage
fault nothing else in that document would show.
Staff keep seeing every file they always saw — withholding is about
recipients, not about the library — so the library now carries the state
on the row: Checking, Quarantined, Released, or Not scanned with the
reason behind it. Nothing at all for a clean file, which is the common
case.
The API says the same in a `scan` object on every file, with an
`available` flag so a caller need not learn which of six states mean
"you can have it", and `scan_status` is a filter, so an integration can
wait for the file it just uploaded or collect what is in quarantine.
The download endpoint answers 423 for a file that is not available,
which it already did through the shared controller.

Client file sharing, rebuilt from the ground up: a private area per
client, resumable uploads, folders, groups and categories, sharing with
expiry dates and download limits, comments, file versions, an activity
log, a REST API, and sixteen languages.
