Shared memory isn't working with node-osrm

[clintharris]

I'm using OSRM-develop (ce784e0491) and doing this to load the shared memory:

$ osrm-datastore /absolute/path/to/data.osrm

I can see the shared memory with ipcs -m. osrm-routed is able to access this shared memory.

Then I'm using node-osrm like this, where data.ini contains same absolute paths to data:

var opts = new osrm.Options("./data.ini", true /*used shared memory*/);
var engine = new osrm.Engine(opts);

node-osrm works, but it's not using the shared memory. I can manually free the shared memory segment with ipcrm -m {shmid} and my node app still does routing, for example.

Any ideas? Is it because I'm not using the latest version of OSRM, perhaps?

Nice catch @clintharris - looks like the option is parsed properly but then overwritten by GenerateServerProgramOptions. So, you need to set sharedmemory=true in your .ini for this option to stick. Overall fix is #29.

Awesome--thanks @springmeyer!
