Error with GTFS-RT feed: schedule_relationship: NO_DATA at a stop

[Nicolas Derive]

Using a GTFS-RT feed with OBA (version doesn't matter), I got this error:

But, I think that when schedule_relationship is NO_DATA for a stop, it means that you have no data, so no delay, departure or arrival time to provide, don't you think? Is this really an error regarding GTFS-RT spec?

Thanks for your help.

Nicolas,

This looks like a bug in how OBA handles NO_DATA in GTFS-realtime.

GTFS-realtime v2.0 docs for StopTimeUpdate (https://developers.google.com/transit/gtfs-realtime/reference/#message_stoptimeupdate) say:

 If schedule_relationship is NO_DATA, arrival and departure must be empty.

Could you please open a Github issue for this?

If you can provide a snippet of the GTFS-realtime data that triggered this it would be great too.

Thanks,

Sean

Sean,

I just reported it here: https://github.com/OneBusAway/onebusaway-application-modules/issues/219

Thanks for looking for a fix.

Best regards,

Nicolas

Dear all,

Is there still a http://nexus.onebusaway.org equivalent somewhere to download latest dev builds?

The more recent dev build I found on it is from January... and that was especially useful to grab latest onebusaway-quickstart-assembly to perform tests...

Best regards,

Nicolas

[Sheldon A. Brown]

Yes,

are you having issues with it?

Here is a link to the latest quickstart assembly:

http://nexus.onebusaway.org/nexus/content/groups/public/org/onebusaway/onebusaway-quickstart-assembly/2.0.0-SNAPSHOT/

Sheldon

[Nicolas Derive]

Yep, I got an error (sorry for not being more specific, I'm not at home with my setup) when loading the database generated with it using a given GTFS file (http://ratp.spiralo.net/stif_gtfs_enhanced_rer_latest.zip) when it was properly working using stable 1.1.18 one.

Is there some more recent prebuilt OBA version, even if it's API only? Maybe I encounter a bug that has been fixed since January, 6th (latest quickstart 2.0.0 snapshot on Nexus)

Nicolas

[Sheldon A. Brown]

Sorry, there is the 1.1.18 release, or the 2.0.0 snapshot. Those are
your best bets.

But do post the error you received on the 2.0.0 snapshot, and I'll take a look.

Sheldon

[Nicolas Derive]

Ok, so let's deal with this. Here is the message I have:

nicolas@caius-bonux:~/transports/oba/dev$ java -Xmx9G -server -Duser.timezone=Europe/Paris -jar ./onebusaway-quickstart-assembly-2.0.0-20180106.065216-46-api-webapp.war -webapp -port=5003 ./

Extracting the bootstrap classpath.  This may take a few moments...

So OBA starts, but it loads nothing, whereas database generation seemed to happen normally (similar debug/info messages
