The OneBusAway#1286 merge dropped the per-agency service date resolution from trips-for-route. Every entry went back to the route agency's service day, including interlined entries whose active trip belongs to an agency in another timezone, and entries on a different service day from their block's active trip. Look up each trip agency's timezone again and resolve the entry trip and the active trip separately, reusing serviceDateResolversByZone from trips-for-location. The entry's schedule uses its own agency's timezone. Restore the cross-agency interlined test assertions the merge relaxed. Its fixture already has UTC and America/Los_Angeles agencies, and both assertions fail without this change. The references subtest in the same test expected both of tfr-xb's stops. On its Los Angeles service day tfr-xb hasn't started yet, so its status only points at its first stop and the response references three stops.

@omlahore do you mind clarifying, in the crossAgencyInterlined block subtest for stops resolved from multiple agencies, which of tfr-xb's stop resolves in references, closestStop or nextStop? |

I think this still leaves a cross-timezone candidate-discovery gap. trips-for-route now resolves service dates per agency after trips have been discovered, but the initial block/layover/null-block discovery still appears to be driven by service IDs from only the queried route agency's current/previous local dates. If an interlined trip belongs to an agency whose local service date differs, that trip's service ID may never be searched, so the later per-agency resolver cannot recover it.
trips-for-location handles this kind of cross-timezone candidate discovery by querying service days for dates localized to each configured agency timezone. Could we refactor that service-day resolution into a shared helper and use it here as well?
For example, the helper could return one or more serviceDayWindows per distinct timezone:
type serviceDayWindow struct {
serviceIDs []string
midnight time.Time // local service-date midnight
sinceMidnightNs int64 // GTFS wall-clock offset for the request instant
}Then trips-for-route could iterate those windows and run its existing block/layover/null-block discovery with each window's serviceIDs and sinceMidnightNs, deduplicating the resulting blocks/trips. That should cover the reverse-timezone case where the queried route agency is still on the previous local date but an interlined agency is already on the next local date.
trips-for-location built its agency-to-location map inline. Move that loop into agencyLocationsByID so trips-for-route can load every agency's zone the same way.
Block, layover and null-block discovery and the active-trip lookup only used the route agency's service IDs and time of day. When an interlined trip's agency is a day ahead, its service ID was never searched, so a block whose running trip belongs to that agency returned no entry. Build a service date resolver for every agency's zone up front, as trips-for-location does, and run discovery over each zone's service days, the route agency's first. serviceDay now carries its midnight so the day a trip was found under is recorded as before. The same resolvers replace the per-trip agency zone lookup. The new test puts the route agency in Los Angeles and the active trip's agency in UTC. It returns no entries without this change.
|
I guess you're right about the gap. I added the reverse case as a test, with the route agency in LA and the active trip's agency a day ahead in UTC, and it came back empty before these commits. I reused serviceDateResolversByZone and ServiceDays() from trips-for-location and just gave serviceDay a midnight, so I hope that's close enough to the serviceDayWindow you had in mind. Discovery and the active-trip lookup go through every zone now, route agency first, and like trips-for-location it doesn't limit a trip to its own agency's zone. |

@JohnAkindipe sorry, missed this earlier. It's both, closestStop and nextStop come out as tfr-agency-b_tfr-stop1 because tfr-xb hasn't started yet on its LA service day. So tfr-agency-b_tfr-stop2 doesn't show up in references at all. |

@omlahore yeah, makes sense, thank you for clarifying 🙏🏽 |

Thanks, this addresses the original gap I was concerned about: the reverse-timezone test is now covered, and the handler is no longer limited to only the queried route agency's current/previous local dates when cross-agency service days are in play.
I do think CodeRabbit's new concern is valid, though. The latest version appears to use the flattened cross-timezone service-day list both for candidate discovery and for selecting the active trip inside each block. That means a trip can be selected as active using a service-day offset from another agency's timezone.
For example, at 2025-06-13T00:30Z:
- UTC query-day offset is
00:30 - UTC previous-day offset is
24:30 - Los Angeles query-day offset is
17:30
An LA-agency trip with GTFS times 24:00-25:00 has not started at that instant, because the LA local query time is only 17:30. But if the block active-trip lookup tests it with the UTC previous-day 24:30 offset, it appears active. The SQL query cannot detect this because it only sees service IDs and numeric offsets; it does not know which agency timezone produced those offsets.
I think the fix needs to keep two phases separate:
-
Route/block discovery
Find blocks relevant to the requested route using the queried route agency's service-day windows. This phase is anchored by trips on the requested route, whose agency is known from the URL route ID. -
Active-trip selection inside those blocks
Once a block is relevant, fetch candidate trips in that block across the timezone-complete service ID set, then validate each candidate trip using only that trip's owning agency timezone before accepting it as active.
A possible shape:
type serviceDaySearchWindow struct {
activeServiceIDs []string
serviceDayMidnight time.Time
queryOffsetFromServiceDayMidnightNs int64
activeSearchWindowStartOffsetNs int64
activeSearchWindowEndOffsetNs int64
}Build both:
windowsByZone map[string][]serviceDaySearchWindow
allServiceIDs []string // union from all windows, for candidate fetching onlyThen:
- Use
windowsByZone[currentLocation.String()]for route/block/null-block discovery, since those are based on the queried route's own trips. - For each discovered block, fetch possible block trips with the timezone-complete
allServiceIDs. - Load/derive each candidate trip's route agency.
- For each candidate trip, get
tripZone := agencyLocations[tripAgencyID].String(). - Validate the trip only against
windowsByZone[tripZone]:- service ID must be in that window's
activeServiceIDs trip.MinArrivalTime <= window.queryOffsetFromServiceDayMidnightNstrip.MaxDepartureTime >= window.queryOffsetFromServiceDayMidnightNs
- service ID must be in that window's
- Pick the matching active trip using the same ordering semantics as the current
GetActiveTripInBlockAtTimequery. - Record
tripServiceDay[trip.ID] = window.serviceDayMidnightfrom the window that actually matched.
That preserves the reverse-timezone fix by allowing cross-timezone candidate fetching, but avoids letting one agency's offset prove another agency's trip is active.
trips-for-route tested every block against the service days of every agency zone at once, so one agency's clock could make another agency's trip look active. At 00:30 UTC a Los Angeles trip timed 24:00-25:00 matched the UTC previous-day offset of 24:30, although it is only 17:30 in Los Angeles and the trip has not started. Find the route's blocks with the route agency's own service days, since discovery is anchored on the route's trips. Then fetch every block's trips across all zones in one query and test each trip only against its own agency's service days, query day first. The cross-agency interline fixture relied on the old match, so its Los Angeles trip now runs 17:00-18:00, when it is actually in service.
GetActiveTripInBlockAtTime and GetTripsInBlock had no other callers.

I think you're right, and I was wrong on the CodeRabbit thread. I split it the way you described, so blocks are found with the route agency's own service days and then every trip in them gets checked against its own agency's days, query day first. I had to move the LA trip in the interline fixture to 17:00-18:00 since it only looked active because of the old match, and your 24:00-25:00 case is a test now that fails before this. |

I merged main in after #1453 landed. I checked CodeRabbit's 3-stop comment too, it's going off the old 24:00-25:00 times, and with tfr-xb at 17:00-18:00 its status points at stop2 as well at 17:30 in LA, so the references test gets 4. |
OneBusAway#1452 moved trips-for-route to blocks scoped to the service day they were found on, with a scheduled-span fallback for blocks between trips. The per-agency zone checks now run once per route service day, so a block ID reused on both days resolves once for each day. A block with no trip running on its day goes through OneBusAway#1452's snapshot resolution on the route agency's clock. Its result is kept only when the active trip's own agency starts that service day at the same instant, so a trip in another zone can't be made active by the route's offset. GetBlocksForBlockTripIndexIDs now takes active and route service IDs separately, and both get the route day's IDs as on main. The service day index constants had no users left.

I merged main after #1452. The zone checks run per route service day now, so a reused block resolves once for each day, and a block between trips goes through #1452's snapshot path. I only keep that result when the active trip's agency starts the day at the same instant as the route's though, otherwise the 24:00-25:00 LA case came back. |

Fixes #1445.
The #1286 merge dropped the per-agency service dates from trips-for-route. Since then every entry takes the active trip's service date in the route agency's timezone. An interlined entry gets the active trip's day even when its own trip runs on the next one, and when the active trip's agency is in another zone the status date is off by the zone difference. The schedule always used the route agency's timezone too.
This looks up each trip agency's timezone again and resolves the entry trip and the active trip separately, like the handler did before the merge. It reuses serviceDateResolversByZone from trips-for-location. I didn't touch the DUPLICATED path because those trips are on the queried route, so I think they already get the right agency.
The cross-agency interlined test already had UTC and America/Los_Angeles agencies. The merge changed its assertions to June 12 UTC for both dates, which is why it kept passing. I put the original assertions back, and both fail on main: the entry serviceDate is June 12 instead of June 13, and the status serviceDate is UTC midnight instead of LA midnight. They pass here, and so do the #1286 past-midnight tests. make test and go vet with both tag sets pass.
newServiceDateResolverFor is still used by trips-for-location, so there's nothing to remove. One cost: serviceDateResolversByZone loads its own service IDs, so a single-zone feed does two more service-ID queries per request.
I rebased this after #1353 went in. Its new references subtest expected both of tfr-xb's stops, and I think that only worked because of the wrong date. On its LA service day tfr-xb hasn't started yet, so the status only points at its first stop. I changed the subtest to expect three stops. It fails on main with that change and passes here.
