Four of the fixes already on this branch were wrong, and an adversarial read
of the diff is what turned them up.
The shared merge helper claimed to implement the server's
COALESCE(assignment_time, place_time) and did not: it pinned the embedded
times to whatever the assignment already showed, ignoring the override
column entirely. Sharing that with the WS applier traded one bug for
another - a collaborator moving a place from 08:00 to 10:00 stopped reaching
the day card for every assignment WITHOUT an override, which is most of them.
It merges the way the server projects now, and the test that was supposed to
pin this seeded a fixture the server could never produce (embedded times that
differ from the pool row with no override to explain the difference).
The per-iteration auth gate went into every loop in tripSyncManager except
the one that matters most: the mutation-queue replay, which writes server
responses straight into Dexie. After a logout that is the shared anonymous
database. The fire-and-forget tags/categories writes two lines below a gate
added in the same commit were ungated for the same reason - they resolve
later, and the check has to happen then.
safeHttpUrl is backed by placeWebsiteSchema: http(s) only, capped at 500
characters. A booking url is deliberately free-form - shared's own contract
says so in as many words, because people paste bare hosts and long provider
deep links - so guarding it with the stricter schema turned a link somebody
saved last year into dead text. safeExternalHref refuses the schemes that
execute in this origin and gives a scheme-less value https://, which is what
an address bar does with the same input.
And the memories timeout was 20s while the server's own budget for a Synology
call is 30s, doubled again when the session has expired and it re-authenticates:
a slow NAS that answered before this branch would have started reading as
disconnected. Those calls had no client timeout at all before; they have none
again, and the ones that need to give up early carry an AbortSignal.
The notes thumbnail also loses its NUL byte cache separator - it made git treat
the whole file as binary, so a security fix landed in it unreviewable - and
gains the same cache cap its chat sibling got.
logout() unregistered every sync trigger, and the only place that registers
them is App's mount effect - which never runs again, because logout navigates
through the router rather than reloading. Log out, log back in, go offline,
edit something: it queues and nothing ever flushes it. No online listener, no
visibilitychange, no 30s heartbeat, no WS reconnect hook. Register on auth
success instead; registerSyncTriggers is already idempotent.
The background sync loops only checked the auth gate on entry. Logout swaps
the Dexie handle to the shared anonymous database, so a trip loop or a blob
download still in flight afterwards wrote the logged-out account's itinerary
and documents into it - the database that survives logout and greets the next
person on a shared device. Check the gate per iteration.
And the remote place:updated applier replaced the whole embedded place, while
the local reducer right next to it preserves the assignment's own times. Same
event, two answers, and the remote one wipes a scheduled 09:00-10:30 off the
itinerary when someone else renames the place. One merge helper now, used by
both, so they cannot drift again. The test that should have caught it seeded
null times and asserted only the name.
Also: moving a day note deleted before it created, and restored the note only
locally when the create failed; t() interpolation was corrupted by a '$' in a
parameter value; a 429 upload was treated as permanently failed; and the
geolocation watch was started inside a state updater.
