Consider way_function, the way object passed in has attributes.
Typically, those are OSM tags, but it does not have to be OSM tag.
For example, you can preprocess non-OSM data into PBF to make it look
& feel like OSM in order to let OSRM digest it.
You can assign your nodes and ways with `ref` identifiers of your own
scheme, it does not have to be OSM identifiers.
Moreover, whatever properties are attached to way objects, you can
access them inside lua profiles
local way_i = way:get_value_by_key('this_is_my_custom_way_id)
local way_n = way:get_value_by_key('this_is_my_custom_way_name)
result.name = way_n
result.ref = way_i
result...
> Can I use property notation like way.id or similar
result.ref
but the value can be based on a custom scheme, it does not have to be
OSM identifiers.

Hi, TL;TR: Is the auto cancellation [1] configured in the Travis CI settings for OSRM? I've been git push -f updating one PR I submitted lately and I suspect the auto cancellation is not configured because arrival of new commit does not cancel the PR build job and the CI resources are unnecessarily kept busy.

[OSRM-talk] error: undefined reference to 'boost::re_detail::cpp_regex_traits_implementation::transform
Hi, I'm building the current master on Ubuntu 16.04 (inside Bash on Windows), using GCC 7.2 and 6.3 and Boost 1.58 - all installed from Xenial packages. I'm experiencing the linker failure for libosrm_extract.a around libboost_regex. It has been a while (~6 weeks) since I built OSRM master last time, but the OSRM used to build fine in that environment. I'm puzzled, because I see the Travis CI builds are perfectly green. I wonder if anyone experienced similar issue. Below, I paste the g++ command with link error.

Re: [OSRM-talk] Example of restricted access flags for way_function and turn_function
Daniel, Thanks for the pointers. I'll check them in details. So, I understand purpose of turn_function is to tweak penalty based on restrictions. I'm wondering about slightly different use case and I'm trying to understand which tool, way_function or turn_function or neither, is the right way to use. Shortly, in my use case a restriction is related to allowed/disallowed turn from one link to another. Let's consider simple network. C | B---A | D Let's assume, all links are bidirectional ways. Node B includes information about turn restriction like so: - turning from AB link to BD link is disallowed - turning from AB link to CB link is allowed AFAIU, object in turn_function has no context related to B node and adjecent links to, eg. calculate artificial high penalty to effectively block AB to BD turn I'm also not sure there is way to include necessary context details in object passed to way_function. But, perhaps I'm missing some advanced profile tricks here. So, does processing of such restrictions fit purpose of turn_function at all? One of feasible alternative approaches is to pre-process such network splitting the B node to B and B-prim A - B - C C - B' - D This would effectively disable travelling along A - B - D I'll appreciate any comments.

[OSRM-talk] [API] Role of profile
Hi,
I'm familiar with role of profile in the OSRM processing flow
as well as descriptions regarding profile and {profile} parameter
in the HTTP API docs.
Still. I'm not entirely clear about the profile role in the HTTP API URLs.
My current understanding is this:
1. profile is actively used during extraction phase of data processing
2. user can feed extraction with any custom profile as long as it is
valid for OSRM
3. generated .osrm package corresponds to single profile used during processign
3. once data extracted and contracted, and complete multi-file .osrm package
is ready, profile is not used
4. osrm-routed serves routing per single .osrm package, so single profile too.
When requesting osrm-route, I noticed
* custom profile is not referenced anywhere
* actually, profile seems not used
For example, I have simplistic .osrm package sample
extracted using custom xxx profile and osrm-routed at
http://localhost:5000, and both requests
return the same response valid for the sample data
route/v1/car/30,20;30,15
route/v1/xxx/30,20;30,15
in fact, any {profile} parameter works
/route/v1/nosuchprofile/30,20;30,15
Now, if I use libosrm API, neither engine config nor any of *Parameters
require specification of profile.
These observations as well as the fact that osrm-routed
serves single .osrm package, so no profile ambiguity is actually
possible, make me think the {profile} parameter in URLs is unused and redundant.
Is that correct?
Best regards

Do you mean, "snap to the same component", either small (SCC) or the global one? > If both coordinates snap to the same small component, then by definition, > you will get a route (this is what an SCC is). Clearly, since every small component is SCC.

[OSRM-talk] Oneway sample: No route found vs Impossible route
Hi,
I'm playing with one way restrictions and I noticed
curious result I'm getting in response to my routing queries
which I can't explain (I haven't dug into the implementation details).
I'm trying OSM file generated for one of the OSRM test scenarios,
namely "Scenario: Car - Two consecutive oneways" [1].
Here is content of the file (w/ timestamp attributes stripped):
I run the OSRM processing and service:
osrm-extract.exe -p C:\apps\osrm-5.5.0\profiles\car.lua
89_car_two_consecutive_oneways.osm
osrm-contract.exe 89_car_two_consecutive_oneways.osrm
osrm-routed.exe 89_car_two_consecutive_oneways.osrm
The following queries return routes, as expected:
1. ab: http://127.0.0.1:5000/route/v1/driving/1.0,1.0;1.0008990679362704,1.0
HTTP 200
2. bc:
http://127.0.0.1:5000/route/v1/driving/1.0008990679362704,1.0;1.0026972038088113,1.0
HTTP 200
Now, I try backward routes:
3. ba: http://127.0.0.1:5000/route/v1/driving/1.0008990679362704,1.0;1.0,1.0
-> HTTP 400: {'message': 'Impossible route between points', 'code': 'NoRoute'}
4. cb:
http://127.0.0.1:5000/route/v1/driving/1.0026972038088113,1.0;1.0008990679362704,1.0?steps=true&geometries=geojson
-> HTTP 400: {'message': 'No route found between points', 'code': 'NoRoute'}
Why the 4th query is responded with 'No route found between points'
instead of 'Impossible route between points'?
I suspect, the way `cb` is treated differently than `ba` during processing.
If it is, what makes the difference?

[OSRM-talk] Is profile_debugger.lua out of sync?
Hi, I'm just starting to learn about OSRM, please forgive me rookie errors. I'm working with profiles and debugging Lua scripts, with help of debug_example.lua, profile_debugger.lua and the provided profiles. I noticed that the scripting environment replicated by the profile_debugger.lua might be out of sync. For instance, profiles like car.lua has got this bit: if highway == "river" then local temp_speed = speed_forw result.forward_mode = mode.river_down result.backward_mode = mode.river_up ... and, while debugging, properties like river_down and river_up are missing. Looking at extractor/scripting_environment_lua.cpp, it seems to me the profile_debugger.lua is out of date. Is my conclusion correct or am I missing any OSRM scripting magic?
