Four separate defects sat behind "offline mode is broken".
The app shell. On the first online launch after a version bump, App.tsx
deleted EVERY Cache Storage bucket and unregistered EVERY service worker,
then reloaded. That is exactly wrong for a Workbox autoUpdate build, which
swaps its precache atomically on install and never leaves an empty one.
Between the purge and the completion of a fresh 22 MB precache the origin
had no shell at all; anyone who closed the app or lost signal inside that
window could no longer start the PWA offline. It also threw away the map
tiles and documents the user had downloaded on purpose. It now asks the
worker to fetch the new build and reloads once it has taken over. The
version marker also moves inside the guarded path, because it was written
after the purge and outside its try: a throwing setItem left the caches
gone, the marker unwritten and the reload unreached, repeating on every
launch.
The reported version is validated before it reaches this device's storage and
before it is compared against the stored marker, so a value that is not a
release tag can neither be persisted nor start an update on every launch.
The session. loadUser's offline branch kept the persisted session but
never called onAuthSuccess, the only caller of setAuthed(true), and the
mutation queue's flush, syncAll and prepareForOffline are all gated on it.
A session that launched without network could therefore never sync again
for the rest of its life, even after the signal returned: the offline
settings buttons spun and returned instantly having done nothing, and
queued edits never uploaded. It also left reads pointed at the anonymous
database instead of the user's own.
The date rule. A trip is only cached when it has not ended, and one that
ended over a week ago is actively evicted. The per-trip switch was an
opt-out list, so ticking a finished trip changed nothing at all. For
anyone whose trips are all in the past, "Download for offline use" stored
none of them, reported success, and the cache stayed at zero. Switching a
trip on now pins it, which overrides both the skip and the eviction, and
the switch shows the honest position rather than promising storage that
never happens.
What the screen says. A sync that never started (already running, offline,
signed out) was indistinguishable from one that stored everything: the
progress bar painted full and a green "Ready for offline use" appeared over
a run of nothing. Both syncs now report why they stopped and the screen
says so. A rejected Dexie read no longer renders as "No trips cached yet",
and the clear button stays reachable when the database holds data that no
bookkeeping row points at. A run that rejects outright says so too: the trip
list it starts from is a plain fetch, so a network blip took the whole thing
down and left the last progress frame on screen looking like a finished
download. The 401-with-HTML branch in the API client now
confirms a reachable proxy before tearing the worker down, since several of
TREK's own routes answer 401 with a text/html body.
Both settings shells move onto one shared hook rather than growing the same
logic twice, and the tile prefetch caps its depth when the browser refused
persistent storage. Opaque tiles are billed at about 7 MB each, and an
origin that is not exempt from eviction loses its whole bucket, precached
shell included, which Workbox then never refills because sw.js has not
changed.
Closes#2228
* fix(security): mint idempotency keys properly, and resolve the extractor by path
Three findings out of a sweep of every open Sonar security issue. The other 49
turned out to be false positives and are documented in sonar-project.properties
rather than changed — each entry scoped to a file, never a whole rule, so a
future Math.random() on an auth path still fails.
The idempotency key is the one that can lose data. Both producers fell back to
Math.random when crypto.randomUUID was missing, and randomUUID needs a secure
context — TREK's own quickstart is http://localhost:3000 and LAN installs run on
http://192.168.x.x, so on the deployments the README documents the fallback is
what actually runs. The axios one was
`Math.random().toString(36).slice(2)`, which is not length-stable: 0.5 yields a
single character and 0 yields the empty string, which the interceptor reads as
"no key" and skips deduplication for entirely. Two writes sharing a key collapse
into one — the second gets the first one's cached response and the edit is gone
with no error anywhere. Both now come from utils/randomId, which has the
getRandomValues rung that works in insecure contexts too.
The extractor probe stored the bare binary name, so every extraction re-resolved
it through whatever PATH held at that moment. The official image sets
KITINERARY_EXTRACTOR_PATH and never reaches that branch, but a bare-metal install
without it ran an unqualified name from a PATH it does not control. It now walks
the search path itself and keeps the absolute path of the file it verified;
execFileSync also drops the /bin/sh hop the old probe needed. PATH comes through
app-config because process.env is walled off in src/.
* fix: four tests and sorts that were not doing what they claimed
Sonar reported 43 high-impact reliability issues. Reading all of them, four are
real; the rest are cosmetic or would be made worse by the suggested change.
budget.test.ts hand-built `paid: true`, but both emitters send `paid: body.paid
? 1 : 0` and the handler stores the value verbatim — the test asserted a payload
the server never sends. The line below it already used a number.
admin.controller.test.ts had a `.resolves` assertion with no await. The promise
was dropped, so that line could not fail the test.
The two to-do category lists sorted with a bare .sort(), which is byte order:
every accented name files behind the whole ASCII range, so in a German trip
"Übernachtung" lands after "Zelt". TREK ships 23 locales, so this is real data.
One side effect worth knowing: katColor picks a category's dot colour by its
index, so re-sorting can move which category shows which colour — it already
moves whenever a category is added, and the colour carries no meaning.
Deliberately not changed: the two `| 0` truncations (Math.trunc is not
equivalent — `| 0` wraps at 32 bits and these carry millisecond timestamps), the
two .map() callbacks whose second parameter is declared and used, and the sha1
in thumbnail.service (its own comment says a swap would orphan every existing
thumbnail).
* refactor: give every button a type, and prefer the Number statics
Two mechanical sweeps, no behaviour change intended in either.
A <button> with no type attribute is type="submit" per the HTML spec. Outside a
form that does nothing today, but it turns into a surprise the moment the markup
is wrapped in one, which is what Sonar's S9011 is warning about. 870 buttons get
an explicit type="button". Two things were left alone on purpose: buttons that
take a {...spread}, because the spread may carry a type and the merge order
decides which wins, and anything inside a <form> — there the answer is a
judgement call, and checking all eleven form files found every real submit button
already carrying type="submit".
The Number sweep covers only the three globals that are exactly equivalent to
their Number twin: parseInt, parseFloat and NaN. isNaN is NOT in it — the global
coerces its argument, so isNaN('abc') is true where Number.isNaN('abc') is false,
and renaming it would change what the code does. It reaches server and plugin-sdk
as well as the client; both copies of egress-policy.ts got the identical edit, so
the mirror the SDK's parity test guards stays intact.
214 items came out of writing the tests. Real defects are corrected, dead code
is removed rather than covered, and the tests that pinned the old behaviour
move with them.
Also drops two agent coverage scratch files that slipped into the coverage PR
and adds the ignore rule that keeps them out.
