Date row now shows All time | 7d | 30d | 6mo | 2026 | 2025 | ... derived
from actual activity data. Year pills use a bounded [Jan 1, Jan 1+1) range
via a new dateTo field on ActivityFilter; rolling-window presets keep an
open upper bound.
Adds a fourth tab visible only on Android API 29+ (full phone, not Karoo).
Filters by sport pill, date preset (7d/30d/6mo/year), and sort order
(newest/distance/elevation). Paginated FlatList with the same activity cards.
ActivityCard extracted to mobile/components/ActivityCard.tsx so both the
feed tab and the new search tab share the same component without duplication.
source_hash: BAS JSON import now computes SHA-256 via crypto.subtle.digest
instead of the '${id}-${length}' stub. No extra package — Hermes supports
Web Crypto API natively.
Feed pagination: useActivities(query, limit) accepts a LIMIT parameter.
The feed screen starts at 50, calls loadMore() via FlatList onEndReached
(threshold 0.3) to increment by 50 each time. useActivityCount(query)
drives the hasMore guard so loadMore is a no-op at the end of the list.
Feed search: compact TextInput below the header filters by title via
SQLite json_extract LIKE. Changing the query resets limit to PAGE_SIZE
so stale paginated results don't linger.
Docs: close the three resolved debt items; keep only the accepted
background-polling limitation as a known gap.
Settings → Sync → Upload format: "Original file" (default) / "Extracted JSON".
- raw (default): reads original_path as base64, POSTs to /api/upload/raw; after
success, overwrites local detail_json/timeseries_json/geojson/source_hash with
the server's DEM-corrected extraction (Option A). Falls back to bas if the file
is missing.
- bas: POSTs pre-extracted JSON to /api/upload/bas, faster, no DEM correction.
Switching modes is safe — the server deduplicates by activity id so a previous
raw upload will return status:"duplicate" on a subsequent bas attempt.
Three bugs fixed:
- /api/upload/bas and /api/upload/raw never updated user_dir/index.json, so
merge_all couldn't include uploaded activities in year shards — they existed
on disk but were invisible to the browser feed. Fixed by _upsert_index_summary()
called before merge_all().
- Silent catch {} in uploadLocalActivities swallowed all per-activity errors;
replaced with console.warn so failures are visible in Expo logs.
- After a server wipe, synced_at flags on the device caused "Nothing to upload"
forever. uploadFeed() now reconciles against GET /api/feed at the start of each
upload: local activities not found on the server get synced_at cleared.
Also: live upload progress ("Uploading N / M…"), failed count in result message,
onProgress callback on uploadFeed(), countPendingUploads() helper.
- Skip MapLibre on Android <29 (Karoo): SELinux denies kgsl-3d0 access
from untrusted_app context, crashing the GPU driver on any OpenGL
surface. Replace with SvgRouteView — equirectangular SVG route trace
using react-native-svg, no native GL surface needed.
- Add +/- zoom buttons to full-screen MapLibre map on modern devices
via Camera ref and onRegionDidChange.
- Skip PyodideWebView on Android <29: same GPU driver conflict; set
_engineUnavailable at module init via API level gate (< 29).
- Add engine_unavailable fast path in PyodideWebView: post message
immediately if WebAssembly.Global is absent (Chrome <69) instead of
attempting 30 MB Pyodide download.
- Add server-side extraction fallback (extractServer.ts): when engine
unavailable, POST raw file as base64 to /api/upload/raw; server runs
full Python pipeline and returns extracted data.
- Add /api/upload/raw endpoint in server.py.
- Add pre-flight auth check (checkServerAuth) before batch import so
an expired token errors immediately rather than after N files.
- Fix uploadLocalActivities in sync.ts: was reading original_path as
JSON (binary FIT file, always threw), silently skipping every upload.
Now reads detail_json from DB directly.
- Redesign Feed header: replace single Sync button with Upload /
Download / Refresh. Pull-to-refresh and Refresh button are local-only.
Auto-refresh on tab focus via useFocusEffect.
- Replace ActivityIndicator with plain Text everywhere (native animation
also crashes Karoo GPU driver).
- Raise macOS open-file limit in dev_test.py to prevent EMFILE errors
from Astro file watcher.
- Document all Karoo hardware constraints in docs/mobile-app.md.
Chrome 61 (Karoo WebView) cannot parse dynamic import() — a SyntaxError at
parse time prevents loadPyodide from ever being defined.
Fix: fetch pyodide.js as text, replace every import( with a __loadScript(
shim that uses <script> tag injection, then inject via Blob URL. The Blob
script is never pre-scanned for module syntax so the patch is invisible to
the parser.
Also: expose waitForEngine() from extractActivity so callers can await
engine readiness before batching files — manual scan now shows "Preparing
extraction engine…" instead of flooding with N individual failures.
Settings: watch directory field is hidden behind a warning if no instance
URL is saved yet, making the dependency explicit before the user sets a
path.
Import: runAutoScan silently skips (no errors) when instance URL is
missing; manualScan shows a single clear message instead of one failure
per file.
The Save button is anchored to the Instance section near the top. Moving
the auto_import_path write to onBlur on the field itself means the value
is persisted as soon as the user leaves the input — no need to scroll up
and hit Save.
- useFocusEffect re-reads auto_import_path from DB every time the Import
tab is focused, so the scan button appears immediately after saving in
Settings (was broken by conditional hook call which violated Rules of
Hooks and never re-fired on setting changes)
- Nested inner try/catch isolates DocumentPicker.getDocumentAsync so
ActivityNotFoundException (Karoo has no DocumentsUI) shows a friendly
message instead of crashing the tab
- Settings watch-directory placeholder updated to /sdcard/FitFiles
Import screen:
- Add "Scan for new rides" button (green) when auto_import_path is set;
shows the configured path, lets user trigger manually in addition to
the automatic scan on app open.
- Detect ActivityNotFoundException from DocumentPicker (Karoo and other
stripped Android devices have no DocumentsUI app) and show a friendly
message directing users to set a Watch directory instead.
- "No new rides found" feedback when manual scan finds nothing.
Docs (docs/mobile-app.md):
- Phase 1 marked complete with implementation notes (wheel delivery,
timeseries workaround, source_path dedup).
- Phase 2 updated to reflect what is actually implemented (on-open scan,
not background task) vs what remains (true background polling).
- Batch import moved from Phase 5 todo to done.
- Data model updated with source_path column.
- Known gaps section revised to remove fixed stubs.
- New Karoo sideloading section with debuggableVariants and armeabi-v7a
troubleshooting notes.
- Import tab now accepts multiple files at once (DocumentPicker multiple:true),
processes them sequentially through Pyodide, and shows a summary with per-file
errors on completion.
- DB migration v2 adds source_path column (original filesystem path before copy)
and an index on it, enabling O(1) deduplication for watch-folder imports.
- On Android, if auto_import_path is set, the Import tab scans the directory on
mount and on AppState 'active' (app foreground), then automatically imports any
FIT files not yet in the DB. Designed for Karoo: finish a ride, open the app,
new files import without any manual steps.
- insertActivity now accepts optional source_path; both importBasJson and
importNativeFile pass it through (null for files picked via DocumentPicker,
real path for watch-folder files).
Diagnosed via on-device debug: build_timeseries produces 3271 points
correctly, but the installed wheel's write_activity has a silent
exception path that skips writing the timeseries file. The workaround
calls build_timeseries directly and writes the file if missing.
Also moves useTheme import to @/ThemeContext across all tab screens.
Replace useSetting()-based useTheme() with a React context (ThemeProvider
+ useTheme/usePaletteControl). The context holds palette key in state so
pressing a palette button in Settings re-renders all screens instantly.
Persists to SQLite and reloads the stored value on mount.
- theme.ts: useTheme() hook with race calendar (May–Sep windows),
auto-detects Giro/Tour/Vuelta by date; stores override in SQLite
- All screens (feed, import, activity, tab bar) now use accent/dim
from useTheme() instead of hardcoded #60a5fa
- Settings: Palette section with Auto/Default/Giro/Tour/Vuelta buttons
to override the auto-detected palette for testing
- Detail screen: Delete button (top-right, red) with confirmation alert;
deletes SQLite row and original file via expo-file-system
- Feed screen: long-press card to enter select mode; checkbox + blue
border on selected cards; bottom action bar with bulk Delete N button;
header switches to show count + Cancel
- db/queries: deleteActivity (returns original_path) and deleteActivities
(bulk, returns all original paths)
micropip requires the full PEP 427 wheel filename (name-version-py-abi-plat.whl)
— writing the file as bincio.whl caused InvalidWheelFilename. The wheel URL from
/api/wheel/version now provides the basename; it flows through fetchWheelBase64 →
extractFile → WebView where the file is written with the correct name and
_wheel_path is set as a Pyodide global before PY_INSTALL_WHEEL runs.
Layout fix: WebView as a sibling in the root layout breaks flex geometry even
with position:absolute. Moving it inside the Import tab screen (which Expo Router
keeps mounted after first visit) eliminates the issue entirely and restores the
original simple root layout.
micropip fix: blob: URLs are not a recognised scheme in micropip — they are parsed
as package requirement strings, producing InvalidRequirement. Write the wheel bytes
to Pyodide's Emscripten FS (/tmp/bincio.whl) and install via emfs:/// instead.
WKWebView blocks HTTP requests (ATS) even when NSAllowsLocalNetworking is set for
the app's own networking — so fetch(http://192.168.x.x/api/wheel/download) inside
the WebView always fails with 'Load failed' on iOS.
- extractActivity.ts: rename wheelUrl param to wheelBase64; WebView now receives
the wheel as pre-fetched base64 bytes rather than a URL to fetch itself
- PyodideWebView.tsx: decode wheelBase64 → Uint8Array → Blob → blob URL for
micropip.install; fix baseUrl '' → 'https://localhost' (null origin blocks fetch
on iOS)
- import.tsx: add fetchWheelBase64() that resolves the wheel URL via
/api/wheel/version then fetches with native networking (HTTP works); caches
result in memory so repeated imports in one session don't re-download
- extraction/PyodideWebView.tsx: hidden WebView (1×1 px, off-screen) that
bootstraps Pyodide v0.26.4 from jsDelivr CDN on app startup; loads lxml,
pyyaml, micropip, fitdecode, gpxpy automatically; installs the bincio wheel
lazily on the first extraction call via a blob URL (avoids startup delay)
- extraction/extractActivity.ts: typed bridge — extractFile(filename, base64,
wheelUrl, onStatus) injects JS into the WebView, tracks pending promises by
request ID, resolves with { id, detail, timeseries, geojson, sourceHash }
- app/_layout.tsx: mounts <PyodideWebView> outside SQLiteProvider at root so
the runtime warms up as soon as the app opens
- app/(tabs)/import.tsx: replaces the placeholder alert with real extraction;
reads files as base64, calls extractFile with a progress callback, stores
detail_json + timeseries_json + geojson + real SHA-256 source_hash; resolves
wheel URL via GET /api/wheel/version with fallback to /api/wheel/download;
falls back to bincio.org if no instance is configured
- Server: POST /api/upload/bas accepts pre-extracted BAS JSON (activity + optional timeseries/geojson), writes files and triggers merge_all
- sync.ts: uploadLocalActivities reads unsynced local activities by original_path, POSTs to /api/upload/bas, marks synced_at on success
- Settings: Upload toggle (Off / Upload local activities) in Sync section with subLabel dividers for Download / Upload groups
- Feed: sync message includes uploaded count when activities are pushed
_merged/index.json is a shard manifest with activities:[] when the user
has >FEED_PAGE_SIZE activities. The endpoint now collects from all
index-{year}.json shard files before returning.
SyncResult gains a `total` field (activities received from server) so the
feed screen can distinguish "server returned nothing" from "all already
stored locally". Messages: "No activities on instance" / "Up to date (N)"
/ "X of N activities synced".
Server (bincio/serve/server.py):
- Add _require_auth: accepts session cookie OR Authorization: Bearer token
- POST /api/auth/token: same as /api/auth/login but returns token in body
(password used once, not stored; mobile stores only the session token)
- GET /api/feed: auth-gated; reads _merged/index.json for the user and
returns the activities array as JSON
Mobile:
- db/sync.ts: syncFeed(db) fetches /api/feed, upserts each summary into
local SQLite as origin='remote'; skips locally-imported activities
- db/queries.ts: add upsertRemoteActivity (INSERT ... ON CONFLICT DO UPDATE
WHERE origin='remote' — never overwrites local imports); fix feed sort
order to started_at DESC instead of insertion order
- settings.tsx: Connect section — password field (not persisted) + Connect
button calls POST /api/auth/token and stores token; Disconnect clears it
- index.tsx: ↓ Sync button + pull-to-refresh both trigger syncFeed; cloud
badge on remote activities; empty state updated
