The credit button sat in the middle of the round controls band, beside the
locate button. On the trip map it now has the bottom right corner to
itself, a gap above the dock (or above the stage bar on the road trip
tab), and the band floats one credit row higher, so the switcher, the
compass and the locate button stay on one line.
MMapArea marks its layer as a credit corner and defines the floor the map
ends at; mobile.css places both GL engines' compact control there, keeps
an opened GL credit's button in the corner, moves the Mapbox wordmark into
the same row instead of under the compass, and unfolds the Leaflet credit
to the left of its button. MapAttributionToggle reads the same two
variables with today's values as the fallback, so the other phone maps and
the desktop keep their placement.
Two faults behind one round button on the phone map.
The base layer switcher that both engines draw in the bottom left corner
sat on top of the GL compass, which started 8px to its left and ran on
under the frosted shell, so it read as a second button showing through.
The compass now stands beside the switcher, placed off the switcher's own
exported inset and size so the two cannot drift apart again.
Satellite never drew on GL because applySatellite gave up whenever
isStyleLoaded() was false and only retried on styledata. That flag is false
while any source has tiles or a setData in flight, which on a phone is the
usual state, and styledata does not fire when those finish. On the road
trip stage every tap met a busy style, because the settings write
re-rendered the shell and handed the map fresh stage arrays. The guard is
gone (the pass only runs after load, and addSource/addLayer only refuse a
style document that is not in yet), an existing layer just flips its
visibility, and a source left without its layer still gets the layer.
The stage data in MMapArea is memoised, so a store write no longer refits
the camera or sets the route, access and place sources again.
A road trip tab on the mobile trip screen: the stage as a chain, the same
map underneath it, the sheets a passenger needs, and a search along the
route.
The addon was desktop only because road trip MODE is a data switch rather
than a view switch. It rewrites `assignments` and `places` for the whole
planner hook, and every mobile sheet is permanently mounted and reads those
same two lists, so turning it on there brought back documented regressions.
The mode flag is therefore untouched. A second flag, `roadtripFeedActive`,
feeds only the routing round and does it off the STORED assignments, so the
phone gets the drive without what the mode drags along with it.
The map is one instance shared by the plan tab and the road trip tab,
hoisted into a single JSX expression so React keeps it in the same position
and the WebGL context is never torn down on a tab switch.
The corridor search is scoped to what a phone can afford: a window of the
day rather than all of it, a smaller tile ceiling, a capped retry pass and a
deadline. The standard search is three requests where the desk makes
fifteen. The categories are deliberately not narrowed, because they all ride
one query per box, so a second one costs nothing.
Two gaps found while wiring it up are closed here as well. The fuel search
drew its offers nowhere on the phone, so the button did nothing visible;
they are in the dry band now, with the detour, the spare range and an accept
button. And the map credit opened as a two line ribbon across a screen the
map fills: both GL engines now start it collapsed, and Leaflet, which has no
collapsed mode of its own, is given one.
iconSize is a PointExpression, which has no x on its tuple form, so the client typecheck refused the size assertion; it now compares against L.point. The test ids follow the FE-PAGE-SHARED-MAP scheme in the order they run, and the comments around the cluster group say in a line what they said in a paragraph.
The Atlas country check timed out. It asked Dawarich for a year of visited
cities in one request, and Dawarich computes that over every point in the
window with nothing cached, so a dense recorder never got under the 15 s the
server allows. The year is now asked for a month at a time, one request after
another, and folded back together. The windows sit a second apart because
Dawarich reads the bounds as inclusive.
The recorded route only appeared after a reload. Every Dawarich call from the
browser carried the shared 8 s timeout, so the browser gave up while the server
carried on and cached the answer for the next page load. Calls that make the
server talk to Dawarich now wait two minutes, the Atlas four. On the GL
renderers the draw also gave up whenever isStyleLoaded() was false, which it is
while any tile is still loading, and only retried on style.load. It now waits
for idle. The hazard overlay had the same guard and gets the same wait. The
pill shows a ring while the route loads, so a slow first fetch no longer looks
like "done, nothing there".
A collapsed day now takes its recorded route off the map, following the same
folds the planner already applies to places, the road trip sidebar's included.
The ways of driving one leg come from OSRM, except the toll-free or
motorway-free offer beside them: the shipped OSRM hosts are built without
excludable road classes and answer exclude= with HTTP 400, so that one is
asked of the avoidance router instead.
Their figures were then read against each other. The quickest was elected
across both, which is what decides the road drawn as the one being driven,
and every other road was labelled with how far behind that election it sat.
The two engines agree on the road to a tenth of a percent and not at all on
how fast it may be driven: over twelve European legs the per-leg time ran
from 14.7 % under OSRM's to 13.2 % over, with the sign following the region.
On a Spanish motorway leg that gap alone is enough to crown a toll-free
detour and call the motorway somebody is on the slow way round.
An offer now carries the engine that timed it. It takes no part in electing
the quickest, no difference is printed across the two, and the bar says where
the figure came from. Each route still reports its own time; only the
subtraction is refused. An instance running its own OSRM through the MLD
pipeline answers exclude itself, so there both figures are one engine's and
the comparison works exactly as before.
Dawarich landed on dev untested, which is why release PR #2273 reads 79.0% on
SonarCloud's 80% new-code gate: 1352 of the release's 4610 uncovered units are
Dawarich's own. 946 cases across 30 files take the surface to 100% in shared,
99.7 in server and 99.6 in client, and the gate to roughly 85%.
What stays uncovered is thirteen type-narrowing guards and defensive fallbacks
the only caller cannot reach, each argued in the file beside it rather than
forced with a cast. No source, config or coverage threshold is touched.
A map keeps the datum it was built with, and Leaflet cannot change one
afterwards. The basemap could still turn into Amap's after the fact: a first
settings request that fails leaves the store on defaults for the session and is
healed later, and the raster layer then drew GCJ-02 tiles under a map still
projecting WGS-84, putting every marker, route and cluster a few hundred metres
off the street beneath it until the planner was left and reopened. The datum is
part of the element's identity now, so a flip rebuilds the map. Only the datum:
keying on the whole tile URL would throw the view away on every template edit.
Index POIs were labelled by an exact lookup of a term the index matches as a
substring, so any leaf that is not literally a term missed and took the first
category of the request instead. In a corridor search that is whichever pill
was tapped first, and the panel groups and colours on that field: a trattoria
came back as a petrol station, or a petrol station as tonight's hotel. The
label now comes from the term that actually matched, longest first.
Two outbound reads were missing what the house rule asks for. The brand-logo
fetch had no deadline at all next to a Wikidata hop that allows six seconds, so
a stalled CDN held a request context and a socket for undici's five-minute
default, and its size cap only applied after the bytes were in memory. The
Wikimedia photo proxy beside it had the same shape. And the Amap provider
buffered every answer uncapped and trusted a cast for its arrays, so a `pois`
object rather than a list threw a TypeError that surfaced as a 500 instead of
the OpenStreetMap answer.
Asked for in the feedback: a wall of round photos, and no way to tell which is
which. "Name and displaying any custom rating would be very beneficial to quickly
seeing what is around you that is of interest."
The collections map had hover switched off. The trip map has told you what a
marker is all along, so it is the same card, now shared instead of written a
third time — it already existed twice, once per renderer, and the two had drifted
in how they resolved the category icon.
The card gains a rating, and so does the marker itself: an amber disc on the
corner where a trip's day numbers sit. The two never collide, because a numbered
stop is one already planned into a day and this answers the question asked before
that. Nothing is drawn for an unrated place, which is most of them.
Also from this round: the place panel's labels move up beside the name, where a
label belongs — read three rows down they looked like a property of the rating
above them — and the rating gets a ground of its own so a line of stars stops
reading as another row of text.
Opening a place sent it from the bottom left of the map to the top, which reads
as the control moving house rather than as room being made. Nothing was in its
way: the inspector is a card centred between the sidebars and at most 800 wide,
so the corner it was clearing is one the card never reaches.
Both renderers, since the switch is not supposed to move when an instance changes
its map.
The trip planner and the journal get a "From Dawarich" list: the stays
recorded for those dates, each one a row that can be dismissed or turned
into a place or an entry after a review step that shows time, name, note
and day. A place that came from a recording carries the Dawarich mark
next to its name so its origin stays visible afterwards.
The recorded route lies over the trip and journal maps as an overlay,
coloured per day and cut along the reader's own timezone rather than
UTC. It is fetched for the window on screen and never stored.
The Atlas gets its own panel beside the map for the countries and cities
the recordings prove, and the wish list is ticked off there, on the day
of the visit, undoably. The phone has its own take on all of it, in the
mobile shell's colours and with native sheets.
Three small things noticed while working nearby, none of them Dawarich:
The map's layer switcher showed the browser's own tooltip while every
control beside it showed TREK's, so hovering along the row produced two
different boxes in two different styles.
The journey entry editor mixed TREK's date picker with a native time
input, and the date, which is the longer of the two, had the narrower
column: "12. Sept. 2026" wrapped while the clock sat half empty. The row
is split in the date's favour now and the picker is disabled together
with the rest of the form instead of staying live behind it.
On the phone's journey, the dock's "+" now turns into an upload button
while the Gallery tab is open, which is what that tab's one big action
actually is.
The share page drew every stop as its own pin while the planner drew the same
trip as a handful of clusters, so a shared link opened on three dozen
overlapping markers. On a 300px-tall map that covers a whole city, the pins
underneath can be neither read nor tapped (#2343).
The option block and the icon factory move to components/Map/markerCluster.ts,
which both maps import, so the two cannot drift apart again. The planner's
options are unchanged.
leaflet.markercluster's two stylesheets were imported by MapView.tsx alone.
The share page never mounts MapView, so it imports them itself: without them
the bubbles keep the library's default styling and spiderfy's legs are
invisible.
A short transport hop is hidden once its two ends sit closer than a few
dozen pixels, so a booking that would draw as a dot does not clutter the
map. That check compared the endpoints, which was the whole line while
every hop was straight. A car booking is routed along the road now, and a
road that leaves a town, rounds a lake and comes back to the next town along
can run across half the screen while its ends project sixty pixels apart.
The whole drive vanished until the map was zoomed far enough in for the
ends to separate, which is the gap in the route the report shows.
The decision now walks the line that will actually be drawn, road route or
arcs, and keeps the hop as soon as that reaches the floor. A straight
two-point hop measures exactly what it measured before, so every existing
threshold holds for the case it was written for. One helper serves both
renderers, which also folds the two hand-copied floor tables into it.
A day that runs past midnight used to keep every one of its stops on its own
card, so day one ended at 03:12 with three places nobody reaches on day one and
day two began with a drive that had already happened. The rail now lays the
stops out by the date they are actually reached: when the clock goes backwards
between two arrivals the ones after it move to the following day, into a block
that says where they came from, and the night drive and its kilometres go with
them. It is an arrangement, not a write — the day planner beside it is
untouched, nothing reaches the database, and a shorter stay the evening before
puts everything back on its own.
The map follows the same arrangement, because a boundary drawn in the rail and
not on the map is two answers to one question. Day one now ends where its last
reachable stop is and the line, the legs and the totals are cut to match.
Two switches in the driving settings, off by default. "Connect the days" routes
the gap between one day's last stop and the next day's first, which is real
driving the rail has never drawn, and counts it. "A colour per day" then puts
the days back into a line that has become continuous, and tints each day header
to match.
Collapsing a day from its header takes its route and its places off the map as
well as out of the rail, and the categories in the corridor panel fold the same
way. The refuel band is one full-width red band with the pump as its button,
the results are chips, and the driving dialog is two columns of panels with the
figures on one right edge.
Also fixes a via that would not adjust the route once dragged. Five separate
causes, all measured rather than guessed: leg threading used the card index
instead of the owning day's, the anchor lookup returned chain indices, it
filtered by the card rather than by the anchor's owner, seams were routed
without their vias, and a seam once routed was never re-fetched.
Four things that only showed up once it was on screen.
The range budget treated a petrol station and a charger as the same thing, so an electric
car pausing for coffee at a filling station had its battery refilled on paper: the
warnings went quiet for the rest of the day and the driver was told nothing. A vehicle can
now be named, and then only what actually refills it counts — and the search asks for that
kind alone instead of offering pumps to a car that cannot use them. Not saying keeps the
old behaviour, which is what everybody who never opens the dialog is on.
The band was its own shape in a rail made of drive bands. It is one now: the same rail,
the same height, the same type size, a warning tint instead of a ring, and the figures
where a drive band keeps them. The buttons are icons of the same 18px square the shuffle
mark uses, so the band stays one line beside its neighbours.
The old range warning stood down where the band shows. Both at once said the same thing
twice in the wrong order — the answer above the problem — because the warning marks the
stop somebody finds out at while the band sits on the leg the fuel ends on.
Two measured corrections to the search itself. The server turns a box into a circle of
half its diagonal and silently narrows anything past 20 km, so a box of ±25 asked for 35
and came back flagged as narrowed EVERY time, which read on screen as "we could not
check"; ±14 asks for 19.8 and is answered in full. And the circle is centred 12 km before
the dry point rather than on it, because only road already driven is any use — centred on
the point, half the circle was spent on road nobody can reach.
An answer that finds nothing now leaves the button rather than only a close. The place
search is a shared public service that does time out, and "it did not answer" with no way
to ask again reads as broken rather than as busy.
Extract the day route builder out of useRouteCalculation into a pure module and
aggregate it over the whole trip: one map with every day's route, each day in its
own colour, the mode per stage and the trip's total distance. Straight lines first,
roads as they answer; a refused leg keeps its line and adds no distance.
Give the floating map controls one shared drop shadow while adding the toggle, so
the new pill and the base-layer switcher stand off the tiles the way the locate
button always has. Document the control in wiki/Map-Features.md.
Addresses #1736
The switch a road tripper keeps asking for has never worked. OSRM's `exclude` is the only
avoidance TREK has, and the two public hosts it ships with answer it HTTP 400 on every
leg: their car profile is built without excludable classes, and their own Lua says why
("no memory for classes on demo server"). So "drive this without the tolls" produced
nothing at all on a default install, and the fallback inside the alternatives bar quietly
gave up after one refusal per host.
FOSSGIS runs a public Valhalla on the whole planet next to that OSRM, keyless, and there
avoidance is a runtime weighting rather than a profile that has to be rebuilt. This adds
it as a second engine asked only the questions the first cannot answer, and puts three
switches under the road trip settings that change the road itself rather than offering an
alternative beside it. Paris to Lyon measured 465.8 km / 297 min with tolls against
492.0 km / 454 min without; Hamburg to Copenhagen comes back ferry-free at 469.8 km,
which OSRM cannot produce at all — where a ferry IS the crossing it answers NoRoute
rather than driving round.
Four things the docs would have got wrong, all measured against the live instance:
- `format=osrm` does not carry `has_toll`. That flag is the entire reason for doing this,
and it exists only in the native answer — which is also 5.7x smaller, because the OSRM
shape drags every intersection along. So the adapter translates instead of borrowing a
familiar envelope.
- Without a `radius` Valhalla refuses a point it cannot bind to a road, where OSRM still
snaps one. Vienna's Stephansdom, in a pedestrian zone, answers error 442 until a search
radius is allowed. TREK is full of such places, so every location carries one.
- Ten locations is a hard cap and a road trip day is bundled into one request. A day over
it is split into runs overlapping by one point, which is exact rather than approximate:
a measured six-stop day came back within two metres and under a second of the same day
asked whole.
- Its drive times run 5.4 % above OSRM's over ten European legs and 36 % above on one, and
those times feed the arrival clocks of a day. So a day is answered by one engine or by
neither, never by both, and a piece that will not answer loses the whole day rather than
half of it — the schedule chains leg times blindly and would otherwise print a complete,
plausible, silently wrong timetable.
Because the weighting can fail, the honest surface is the answer rather than the request.
`use_tolls: 0` still returns a tolled road where there is no untolled crossing, so what
the road actually turned out to be is read back per leg, and a day that could not avoid
what it was asked to avoid says so on its own header instead of wearing a label the road
disproves. The switches disable themselves, with a reason, on an instance pointed at its
own OSRM: that operator chose against public hosts, and a second one they never asked for
would undo the choice.
Two things that would have broken quietly and did not:
- The route cache keys on `profile:unit:coords` and is shared with the day planner, the
studio and the booking geometry. Without the avoidance in the key, flipping a switch
returns the old road out of cache in under a millisecond — and worse, an avoiding answer
stored under the plain key hands those other callers a road nobody drives.
- `snapped` is OSRM-only and carries the dashed kerb-to-door spur from #2273. Valhalla
echoes the coordinates it was given and never says where it bound them, but the ends of
a leg's line are exactly those points: measured against Füssen, its first vertex matches
OSRM's snapped location to the digit.
The alternatives bar gets the same engine, which finally makes its "no motorway" and "no
tolls" offers appear on a default install, plus a ferry-free one. `sameRoad` now compares
geometry rather than numbers there, because two engines' distances for the same road sit
kilometres apart and the old 200 m tolerance called that a discovery.
Desktop only, like the whole road trip mode: nothing under client/src/mobile renders it.
The imagery toggle has been there for a while and only ever worked on Leaflet, so
anyone on MapLibre or Mapbox — which is the default since the vector basemap landed —
had a switch they could not see and a view they could not reach.
Leaflet swaps its whole tile layer for the imagery. A GL map cannot: its basemap is a
style with dozens of layers in it. So the same tokenless ESRI source goes on as a
raster layer of its own, inserted before the first layer TREK draws, which leaves the
route, the pins and the tracks on top and legible. Switching back hides it rather than
tearing it down, so going to and fro does not re-fetch a tile.
Built on demand rather than once at load, because a basemap change rebuilds the style
from scratch and takes every source with it; the styledata event is subscribed for the
same reason. The switch reads the setting the Leaflet map already stores, so the choice
survives an instance changing renderer, and it sits in the same corner with the same
offsets.
Every route is calculated in the browser against the public FOSSGIS hosts, so the
server never sees a routing request and nobody has a number: not how many a real trip
costs, not how big they are, not how much already goes to a self-hosted engine.
Deciding whether TREK could run its own router without that number is guessing at the
bill, and the counters have to be collecting before the question comes up.
Counters, not a log. A row is a day, a profile, a request kind and an engine kind with
totals on it: how many requests, how many waypoints, roughly how far, how many were
refused. No query, no coordinate, no route, no user, no trip. Nothing leaves the
instance: its own database holds them and its own admin reads them at
GET /api/route-usage/summary.
The client tallies in memory and flushes in batches — on a timer, past a threshold and
when the page is hidden — because a counter that cost a request of its own would
measure the load by adding to it. Routing all funnels through one fetch in
RouteCalculator, so that is the only place instrumented.
On by default and switchable off with route_usage_enabled, unlike the shadow log next
door: that one stores what people typed, this one stores four integers about a day.
The category pill was switched off whenever road trip mode was on, which left the
corridor search as the only way to find anything. The two answer different questions
though — 'what is along this drive' against 'what is in view right now' — and looking
for a hotel at tonight's stop is exactly the second one. Furkot shows accommodation
at a stop for the same reason (disc #1797 thread).
Both searches now draw together. A place found by both appears once, as the corridor
knows it, because only that copy carries how far along the drive it sits, and the
merged list keeps its reference while nothing changes so the map does not rebuild
every pin on each render.
The satellite toggle sat on an offset that included --day-panel-h, so it hopped
every time the day panel was collapsed or expanded. On the desktop map that
panel is a centred card between the sidebars and never reaches the pill at the
left edge, so the lift only applies on a phone now.
In the places rail the two add buttons split the width evenly once a day is
open, and every button drops to its icon when the rail is dragged narrow. The
filter tabs span the rail and keep their own text widths. The count is a badge
across the rail; the search field got the outline the controls around it use.
An empty day offers a button that opens the place form pointed at that day
instead of only stating that nothing is planned. The day is cleared again when
the form is opened to edit, which it was not before.
The trip tab bar no longer carries a native title repeating its own label; the
full name moved to aria-label for the tabs whose label is abbreviated.
Three maps tests drove the index switch through app_settings, which no longer
holds it, and now move TREK_PLACES_ENABLED instead.
The default basemap has been a vector style since 4.1.0, and maplibre-gl builds
its WebGL context inside the Map constructor. A browser that refuses one throws
from there, and VectorBasemap attaches the layer inside an async effect, so the
throw became an unhandled rejection no boundary could see.
What actually took the page down was the teardown. Leaflet registers a layer
before onAdd runs, so the half-built one stayed on the map, and the bridge's
onRemove calls this._glMap.remove() without asking whether there is one. That
TypeError lands in a React cleanup, which is why the error appears on the way
out of a map rather than on the way in, and why it reads as "Something went
wrong" when a tab changes and "TREK could not start" when the route does.
The browser is now asked first, once per page load, with a one-pixel probe that
hands the context straight back. Without WebGL the basemap is OSM raster tiles
instead of an empty map, and the maplibre chunk, about a megabyte, is never
fetched. The teardown path is safe either way: a half-built GL layer gets a
no-op stand-in so the bridge can finish its own cleanup, and detaching never
throws, because unmounting a map must not fail just because its basemap did.
Reproduced against demo.liketrek.com with WebGL switched off, and verified with
the fix: 14 raster tiles drawn, no GL canvas, no error screen.
Closes#2288
Five things, all of them a click or a drag doing something the traveller did not
ask for.
The GL via handle committed a move on every pointerup. Any button started the
drag and there was no movement threshold, so a plain click wrote the via to
wherever inside the 17px handle the pointer happened to be — at a low zoom that
is kilometres, and the write re-routes the whole trip. A right-click ran the
drag AND the delete, so one gesture sent two writes; on the platforms where
contextmenu comes first, the move landed on an id that no longer existed and
reported a failure for a deletion that had worked. Leaflet gets this right for
free from `dragend`, which is why the two renderers behaved differently for the
same gesture. Primary button only now, with a threshold, and pointercancel puts
the pin back instead of committing — the browser fires it when the captured
element is torn out of the DOM, which is exactly what a delete does.
With the alternatives picker open, one click on the route fired both handlers.
Layer registrations are independent in MapLibre, and every alternative starts
and ends at the same two stops — when the leg already carries vias the current
road is itself one of the offers, so the overlap is the whole leg. The click
dropped a via AND chose a different road: two writes and two trip reloads for a
gesture made once.
The corridor search could be started before the day had routed. The corridor is
then built from the straight line between the stops rather than the roads
driven, and the routing answer landing a second later changes the line, which
clears the search mid-flight and drops every result — no error, no partial
result, just the idle empty state again. Routing runs one day at a time about a
second apart, so the window is wide open on a long trip.
Leaving road trip mode left the alternatives drawn on the map. The switch is in
the sidebar and reachable while the bar is open, and the overlay depends only on
the picker, so pale blue routes with drive-time pills stayed on an ordinary
planner map with no road trip UI left to dismiss them from.
Clearing a leg's vias swallowed its failure and closed the picker anyway. Every
neighbouring write in that hook reports one. The leg still carried its via and
still routed the old way, so the traveller believed they had undone the detour.
Walking and cycling legs were counted as driving. A day may legitimately mix
modes — splitIntoRuns exists for that — and a two hour hike was reported as
"over the longest drive allowed", its minutes went into the day's driving time
and its kilometres onto the tank, where a ferry crossing could trip a range
warning outright. A leg with no mode still counts, because every leg was a drive
before the field existed.
The road-trip domain also says out loud that it is online-only, which the repo
asks for rather than leaving it to be discovered. A via anchors by POSITION, so a
queued write replayed after somebody else moved a stop would re-pin the drive
onto a leg nobody chose, silently and hours later; the offline story needs the
anchor to be an assignment id first. Until then the surfaces disable the gesture
instead of accepting one and dropping it.
Six theme-lint markers move onto the line they exempt. The linter suppresses per
line, so a marker in the comment block above suppressed nothing and the six
road-signage colours the authors documented as intentional were counted anyway.
Placing one triggers a re-route, the re-route lands about a second later, and
the render it causes rebuilt every via handle — which is exactly when somebody
reaches for the dot they just made. On the GL renderer that rebuild replaces
the DOM element outright, and a pointerdown belongs to the element it happened
on, so the drag went to an element that no longer existed. The second attempt
worked because by then nothing was pending, and an older via never showed it
because nothing was re-routing.
Two causes, both identity: the vias arrive as a fresh object on every reload
even when the rows came back identical, and `onMoveVia` is a fresh closure on
every render of the planner. Both were in the effect's dependencies.
The list is now keyed by what a handle is built from — id and position — so it
only changes when a via does, and the callbacks are read through a ref. A via
that genuinely moved still gets a new list, which is what redraws it where it
now is; the test pins both halves, because holding the element still must not
mean holding it in the wrong place.
Leaflet's markers had the same churn without the same symptom: a fresh
`position` array called `setLatLng` on every marker on every render, and a
fresh `eventHandlers` object unbound and rebound every listener. Same fix.
The vias already made the day follow the road; nothing said which road. After a
reload the badge could only say "shaped by hand", and re-fitting after the stops
changed meant finding the track again by eye.
One row per day, written in the same transaction as the chain it describes: a
day claiming to follow a road whose vias never landed would be worse than a day
claiming nothing. Three states rather than two, which is why the field is an
object and not an id — absent leaves whatever the day followed alone, null says
it follows nothing, an object records the road it now takes. A bare nullable id
could not tell "do not touch this" apart from "forget it", and a hand-dragged
via on the same day must not wipe the label.
The foreign key is the point: delete the imported track and the label cascades
with it, so no day is left claiming to follow a line nobody can see. The vias
stay, because they are the drive.
Both write paths check that the place is a track of this trip before it becomes
a label — permission alone would let another trip's place id, or an ordinary
place, become a name that can never be drawn.
Also clears three reliability findings the scanner raised on this branch: two
default sorts given an explicit comparator, and a trailing-slash regex the
scanner is right to call backtracking, walked instead.
The corridor query has always ended in `out center tags`, and the projection
has always kept six keys out of the whole tag set. Everything an electric car
needs to know was in the answer and went in the bin: which plug families the
station has, how many of each, at what power, how many vehicles fit, and whether
it charges. Reading them costs no extra request, no key and no second query.
The filters treat "not stated" as its own answer, which is the only honest way
to build them: OSM states a socket type on roughly a third of charging stations
and a power on fewer still, so a power filter keeps every station that says
nothing rather than reading silence as too slow. The plug dropdown offers only
the families this search actually turned up, because CHAdeMO in a list for a
corridor with three Type 2 posts on it is a filter that can only return nothing.
Socket names stay as they are printed on the plug. "Type 2" is not a string
anyone translates, and the lowercase tag key is not what is written on the
charger.
The tool description follows, as parity requires, including the coverage caveat
— a model that reads a missing power as "no fast charging here" would be wrong
about most of the map.
Reported from a real trip: Hamburg, A1, HEM, Berlin. HEM to Berlin is 244.7 km,
and the badge on Berlin said 121 — which is the length of the NEXT leg, Berlin
to Sanssouci. The finding was anchored to the stop the leg departs from while
its wording ("since the last fill-up") is a running total, so the number never
matched what anyone adds up off the drive bands above it.
Both findings are true on arrival, so that is where they belong. The same trip
now reads 125 at HEM (21.5 + 103.4) and 245 at Berlin, which is exactly what you
get counting the bands.
A service stop carries them too. A charging halt is a stop like any other as far
as the tank is concerned, and HEM was the very stop whose figure went missing.
The corridor's empty state gets the mascot the rest of TREK uses: searching,
idle, and a confused look when a filter left nothing standing, so the picture
says which of the three it is before the sentence is read.
A router snaps every waypoint to the nearest road before it starts, and OSRM
does it with no distance limit at all. A viewpoint above a valley, a farmhouse
down a track, a marina at the end of a pier: the drive to it really begins
somewhere else, and the line said nothing about that. It either stopped short
for no visible reason or appeared to cut across open ground.
OSRM reports the snap position and its distance in every single answer, and
this client has thrown both away since the first route was drawn. Reading them
costs no request and no key.
The gap is drawn as a dashed spur in the route's own blue, over the route
rather than under it, because it is the one piece of the line that is not
driving. Thirty metres is the floor, which is about a dual carriageway and its
verge, so a place pinned off an aerial photo does not earn a dash. From a
quarter of a kilometre the rail prints the distance too, because that is where
"the car park is over there" turns into luggage, a gate, or a track a hire car
should not be on.
Vias are deliberately left out: a via is a shape handle, not a destination, and
a dash hanging off one reads as a fault.
Both public hosts TREK ships with reject the parameter with HTTP 400: their car
profile is built without excludable classes, and only a self-hosted OSRM built
through the MLD pipeline has them. Every long leg was therefore paying two extra
requests, against a host that allows one per second, to be refused twice.
The first real attempt is the probe. Only a 400 is remembered, because only a
400 is about the host: a 429 is a rate limit, an abort is the user moving on,
and a NoRoute means this leg has no way round the motorway while the next one
might. Kept per base URL, so pointing the instance at an own router that does
support it starts asking again without a reload.
The comment above the fallback said none of this and read as a working feature,
which is why "only one sensible way to drive this" keeps appearing on legs that
plainly have another road.
The kinds were written out in nine places: the enum in @trek/shared, the
service list and the colours in the model, the corridor's category keys, the
map's road-trip categories, the popup's own table, two lookups in the rail, one
in the map markers and one in the corridor panel. Each carried a comment asking
the next person to keep the others in step, and it came apart anyway.
A rest area was a parking sign in the popup, on the map pill and in the panel,
and a coffee cup on the rail disc and the map marker, for the same stop. The
parking sign wins: the colour has been documented since it was written as "the
blue every parking sign in Europe is printed in".
stopKinds.ts holds one row per kind and everything else reads from it. It sits
beside the model rather than inside it because an icon is a React component and
roadtripModel.ts is deliberately React-free so the arithmetic can be tested on
its own; the colours and the service list stay there and are read from here.
Two flags rather than one, because they are not the same question: a hotel is
something the corridor can find, but sleeping somewhere ends the day rather
than interrupting the drive.
Seven tests pin the table against the two lists that cannot import it, so the
next kind added in one place and forgotten in another fails a test instead of
quietly counting as a destination.
The road-trip addon's second half: the parts that let a planned drive be
argued with rather than only read.
Reshaping. A via records which stop it follows by position, and that position
is resolved fresh every time the day is routed — so inserting, reordering or
removing a stop moved the ground under every via after it, and the drive
silently snapped back to the road it had been steered away from while the
handle still sat on the map where it was left. The correction is computed
against the day as it stands and written with the same change, in one
transaction: a half-applied re-anchoring mixes two numbering schemes in one
day. The one judgement that needs geometry — which half of a split leg a via
belongs to when a stop lands in the middle of it — is measured on the road
actually driven, so a fuel stop added to a bent leg keeps the bend on the side
it belongs to.
Alternatives. OSRM answers most long legs with exactly one route, which read as
"there is no other way" when a perfectly good slower road existed. When it
offers nothing, the same drive is asked for again without the motorway, and
failing that without the tolls — one question at a time, stopping as soon as
one lands. The offer says what it is rather than how much slower.
Stops along the way. Everything the corridor search can find is a pause, not a
destination: fuel, charging, rest areas, campsites, food and sights all sit
inside the leg they were found on, carry their own colour and icon, and are
left out of every stop count. That colour is defined once and read by the rail,
the corridor list, the map pin and the picker — and it replaced the chains'
logos, which turned a corridor full of petrol stations into a row of
advertisements and left the brands with no logo on file looking like something
else entirely.
How long a stop takes was readable in the rail and writable nowhere; new places
were given an invented hour that nobody had entered. It is now set from the
rail, cleared as a zero because the update statement folds a null into "leave
it alone", and new places start with nothing.
Both columns are rebuilt on one type scale, anchored to the day plan's own
sizes so switching tabs does not change the size of the text beside it. The
rail reads as trip totals, day cards and a chain of stops with the drives
between them; the corridor column as what to look for, how the search is
getting on, and what it found. Six category pills over three lines became one
dropdown, which is the space the results wanted.
Also: the offered routes are framed on the map when the picker opens (`fitKey`
carries no coordinates and each renderer reads it as "the selected day"), road
trip mode does not cluster at all so the whole drive stays readable zoomed out,
and the drive-time labels finally render in the app's own typeface instead of
Leaflet's Helvetica. All of it in both renderers.
The road trip corridor asks for fuel, charging, rest areas and campsites over a
dozen boxes, and asking per category was four times the requests for the same
answer — slow, and four times the chance a shared Overpass mirror times out and
reports the stretch as unsearched.
`category` now takes a comma-separated list. Each OSM selector belongs to exactly
one category, so a hit is still labelled with the kind it answered, and the
result cap is shared out per category so one dense kind can't crowd the rest.
The MCP tool takes an array for the same reason.
Also puts the POI, plugin and route via-point pins on the map's render clock,
the same fix the planned-place pins already had: a library marker repositions on
every pointer sample while the canvas draws once a frame, so the suggestions
swam during a drag and snapped back on release.
