Re: [OSRM-talk] hsgr error after many requests

[Steven M. Ottens]

Hi Daniel,

I was using the development branch of osrm-backend and the standard (eg 
npm install osrm) version of node-osrm. Since I couldn't figure out how 
to get the correct version of node-osrm installed on the remote machine 
I redid the entire process with the master branch.


It works now, thanks for the help,

Steven

When you say

could it be that you ran osrm-extract / osrm-prepare (in develop 
branch now named osrm-contract) on .pbf files while on osrm-backend 
version N.
And now you updated osrm-backend to version N+x but you're still 
feeding it the old .osrm files? This is so far the only way I can see 
this happening.


Can you try reproducing the issue by running the toolchain on your 
.pbf extract.

That is put away the .osrm files for a moment and generate fresh ones.
Then run osrm-routed / node-osrm.

Cheers,

Hi all,

I'm busy trying to build a program that, given a road network, a
series of villages and a series of POIs will calculate the time to
the nearest POI for each village. There are 215000 villages and
85000 POIs, so I split the region in smaller squares to speed up
the process, I end up with 500 squares and for each square I get
the villages within the square and the POIs within a buffer around
the square. I run these two through osrm.table to get the time to
the nearest POI.

This works fine and my server slowly chugs along until at some
point (after 15 minutes and a hundred+ squares) I get this error:

TypeError: hsgr input file misses magic number. Check or reprocess
the file

I find this weird since I have done the entire set before (with a
less elegant approach, but with the same *.osrm* files) and why
does this error only show up after a while.

If anyone has any insights I'd be much obliged,

Steven

[OSRM-talk] Demo server switchover to OSRM 5.0 and new HTTP API

[Johan Uhle]

Hi All,

some of you are using the demo server at https://router.project-osrm.org in
your own projects. This message is to notify you of upcoming changes there.

For a while we've been working on OSRM 5.0.0, which will bring big changes
to the osrm-routed HTTP API. You can see the new HTTP API here
https://github.com/Project-OSRM/osrm-backend/wiki/New-Server-api. We will
soon switch over the demoserver to this new API, likely beginning of April.
Below are the details:

- We will announce the exact date and time of the switchover 7 days in
advance in this issue and on this osrm-talk mailing list
- We will release a _release candidate_ before doing the switchover
- We will not release the final version of OSRM 5.0 before doing the
switchover
- If you want to test the new API now already, set it up yourself from this
branch https://github.com/Project-OSRM/osrm-backend/pull/1935
- We will not provide the old and new API at the same time, but do a hard
switchover of the demo server
- To be notified specifically when the change will happen, you can drop a
comment on this Github issue
https://github.com/Project-OSRM/osrm-backend/issues/2126

Comments are appreciated, either here or on the Github ticket
https://github.com/Project-OSRM/osrm-backend/issues/2126

Best,
Johan
