Requests timing out

[ltsstar]

I am currently (just) using a script that calculates hundredthousands of routes using OSRM.
What I recently encountered is, that the OSRM backend fails on some routes, even though they appear completely legit.

I reproduced some routes on the demo server and encountered the same problem:
For instance, see this:http://map.project-osrm.org/?z=13&center=50.940204%2C6.460218&loc=50.908256%2C6.407245&loc=50.965147%2C6.460674&hl=en&alt=0

with the corresponding request:https://router.project-osrm.org/route/v1/driving/6.407245,50.908256;6.460674,50.965147?overview=false&alternatives=true&steps=true&hints=;

@ltsstar can you compile in Debug mode and see if an assertion triggers? We currently have a number of errors on the demo server triggered by requests that trigger faulty assertions.

[ltsstar]

compiling in Debug mode and running osrm-contracts results in an assertion error in coordinate_extractor.cpp: https://github.com/Project-OSRM/osrm-backend/blob/master/src/extractor/guidance/coordinate_extractor.cpp#L429

I'm not completely sure if the problem is the same, but i am facing a problem in all the requests that i make, doesn't matter what i am requesting.

The examples from the documentation are throwing internal server error :
(Table)
http://router.project-osrm.org/table/v1/driving/13.388860,52.517037;13.397634,52.529407;13.428555,52.523219

&
(Route)
http://router.project-osrm.org/route/v1/driving/13.388860,52.517037;13.397634,52.529407;13.428555,52.523219?overview=false

Also, the demo http://map.project-osrm.org/?z=13&center=38.927633%2C-77.046604&loc=38.949397%2C-77.062912&loc=38.917082%2C-77.063427&hl=en&alt=0 throws :

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://map.project-osrm.org' is therefore not allowed access. The response had HTTP status code 500.

@ltsstar the whole area is separated from the road network by nodes like http://www.openstreetmap.org/node/278734454. It is also not a small component, so it is not ignored for snapping the start point and is routable internally

http://localhost:5000/route/v1/driving/6.407245,50.908256;6.417625,50.907769.json

{ "code": "Ok", "routes": [ { "distance": 1072.3, "duration": 81, "geometry": "_avuH{ibf@Fh@ILiCqJKu@Fm@`Saa@\\sAwFyJ@k@[?eB_D", "legs": [ { "distance": 1072.3, "duration": 81, "steps": [], "summary": "" } ] } ], "waypoints": [ { "hint": "-wQAgP0EAIAAAAAAAAAAAAwAAAAAAAAAGQAAANsDAACQAgAACwAAgMnCYQA8zQgDTcRhAGDMCAMAAAEBjUCmSQ==", "location": [ 6.406857, 50.908476 ], "name": "" }, { "hint": "IQIAgNYCAIAAAAAAMQAAAAMAAAAHAAAAAAAAAAACAAACAgAACwAAgC3tYQBFyggD2exhAHnKCAMBAAEBjUCmSQ==", "location": [ 6.417709, 50.907717 ], "name": "" } ] }

Profile modification is needed to unconditionally allow routing via private gates.

@danpat This is a use case for https://github.com/Project-OSRM/osrm-backend/tree/opening_hours with access tag where penalties should be set to "infinite" value if condition is false to separate the area from the road network.

Closing here. The original comment was about not routing over a private node:
http://www.openstreetmap.org/node/278734454#map=16/50.9095/6.4325

@oxidase is currently building an opening hour grammar parser for these conditional restrictions:

• Added opening_hours grammar #3415
• Support for conditional restriction and/or speed limits #3414

If you unconditionally route over those check profiles/car.lua and adapt the access tags appropriately.
