when reticulate restarts, reticulate initializes Python from within an RPC method call (from ark) which in turn does not allow us to call into `getIpykernelPath` (which happens when registering ark methods) The solution here, is to store the ipykernel path when starting positron, so we don't need to later call into the UI comm to get it.

Thanks Daniel! Do you know if we have a positron:reticulate test that will fail if the return value of |

Yes, I assume this will fail https://github.com/posit-dev/positron/blob/77f51685f2bb19b2493e03bbe5e5eb9aa89a22dc/test/e2e/tests/reticulate/reticulate-variables.test.ts#L15 if this changes. Unfortunately, most reticulate tests are disabled on Positron CI due to an issue with reticulate on linux. |
