Cannot start multiple rservers on multi-user system #33

Closed ryanlovett closed 5 years ago

ryanlovett commented 6 years ago

The change to rserver causes this extension to fail on multi-user systems. When rserver starts, it create /tmp/rstudio-server/secure-cookie-key. If a second user attempts to write there, rserver will fail. This is not configurable within rstudio.

I'm thinking of introducing a traitlet that lets administrators choose between rsession and rserver. Thoughts?

I think this is related to #44 as well?

yuvipanda commented 5 years ago

Once we switch to simpervisor in nbserverproxy, maybe we can revert to using rsession? I don't think this should be configurable if we can find a proper automatic solution

If I simply switch I am getting:
